Steel structure is a structure composed of steel

Steel structure is a structural composed of steel materials, which is one of the main building structure types. Steel structure warehouses installation quickly , the structure is mainly composed of steel beams, steel columns, steel trusses and other components made of shaped steel and steel plate, etc., and usually welded, bolted or riveted joints are used between each member or component , because of its light weight and simple construction, is widely used in large factory buildings, venues, super high-rise and other fields.

1. Before the steel structure is installed, all kinds of records and reports should be checked, such as quality certificate of components, material test report, non-destructive inspection report of welding seam, etc., and the appearance of components should be checked to see if they conform to the design requirements, and the problems should be corrected immediately.

2. The installation flow chart of the steel structure is drawn and installed according to the flow chart. The precision of all anchor bolts should be checked before installation, and the spatial position and design drawing should be corrected timely to ensure the accuracy of anchor bolts.

3. The mounting sequence of the components should be carefully designed to form a rigid body as soon as possible so that the installation can be continued in a stable state, and also to eliminate errors in the installation of the steel structure.

4. Component assembly should undertake the necessary checking calculation. The lateral stiffness of small component measures should be taken to avoid the distortion and damage.

5. In the process of columns or steel structure installation, beam and steel support should be installed in a timely manner, temporary fixed cable wind rope should be added when necessary.

6. It should pay attention to controlling the influence of temperature difference on the perpendicularity of components for the installation of steel column, adjust the lateral quantity to the perpendicularity of the first determined standard column, and check other columns.

7. When the column is installed, the positioning axis of each column must be directly drawn from the control axis on the ground, and the top axis of the column of the next column shall not be used as the positioning axis of the upper column.

8. Steel structure installation spot welding environment, welding position, high altitude, air temperature and humidity adverse effects for susceptible to weld defect, therefore, must take appropriate measures to overcome the impact of these unfavorable factors. The unqualified weld rework repair is not allowed to exceed twice.

9. High strength bolts using torque wrench must be correction calibration before use, should check after use, once found that the torque error exceed the permitted range, the twist of the wrench bolt were all unqualified.

The high-strength bolts should be tested after final screw, and the nuts can be tested one by one by means of small hammering. Torque should also be sampled check.

10. After the Steel structure installation is completed, and correct after correction, it should do the second grouting in time for the space between the column bottom and top of the base to make sure the surface contact base plate and foundation top tight.

11. After completion of the whole steel structure installation, it should be according to “the steel structure engineering construction quality acceptance standard “(GB 50205-2001) requirements for acceptance.

The simplification of modern architectural design is ideal for prefabricated houses

Building a China prefabricated homes typically involves attaching pipes and wires to the parts and sealing the parts together. The house made can be single, double or triple, describing its width. Many manufactured home companies make a variety of different designs, and many floor plans are available online. The house can be built on a permanent basis, and if properly designed, it is difficult to distinguish it from a strong house to an untrained eye.

A prefabricated homes China, once assembled, will undergo a “relocation” period in which the house will be located. During this time, some drywall cracks may occur and any equipment, wires or pipes that are not properly installed should be repaired and are expected to be under warranty. If it is not covered by the warranty, the cost will be borne by the consumer. Therefore, it is important that consumers ensure that reputable and honest contractors are used for initial setup. If the initial installer does not complete any repairs, the manufacturer will dispatch a service person to repair any repairs covered by the warranty. A secondary maintenance team must be arranged and most repairs may not be available immediately. Just because the assembled home does not mean that it can live immediately; the proper ventilation, heating, piping and electrical systems must be installed by the installer, otherwise the buyer must wait for the manufacturer's maintenance team or complete it on their own.

The first prefabricated houses and movable buildings were invented by Akbar in India in the 16th century.

Prefabricated homes are becoming more popular in Europe, Canada and the United States because prefabricated homes are relatively cheap compared to many existing homes on the market. However, the 2007 financial crisis has devalued housing costs in North America and Europe, so not all prefabricated homes should be considered cheaper than existing homes.

Modern architects are experimenting with prefabricated means of providing modern homes that are well designed and mass produced. Modern architecture gives up the reference decoration, but has clean lines and an open floor plan. Due to the simplification of design provided by modern buildings (plus the cost savings from simplified design), many manufacturing residential sectors generally believe that modern architectural design is prefabricated homes China.

In fact, the potential market space for steel structures is very large

Judging from the actual situation in our country, the construction industry does not pay enough attention to steel structure. At present, the proportion of prefab steel house in China is only 6% ~ 8%, while the proportion of railway, highway and municipal steel bridges is less than 1%. However, the proportion of construction in steel structure housing in Japan, the United States, Britain and other countries has reached 30% ~ 60%, the proportion of steel bridges in about 600,000 bridges in the United States has reached 33%, and the proportion of steel bridges in about 130,000 bridges in Japan has reached 41%.

In the field of civil construction, especially in the field of steel structure residence, the owners have not paid enough attention to the use of steel structure. " Most developers don't make steel-structure houses, and the design and construction departments are accustomed to traditional building methods. Only by guiding developers to try to use steel structures and giving them a " sweet taste" in the process can this situation be changed.

It is hoped that the government can introduce some incentive policies in promoting the development of steel structures. For example, when approving the construction projects of investors and real estate developers, a certain proportion will be reserved for steel structures.

In fact, the potential market space of steel structure is very large, and the technical threshold is not high. Once there is a policy incentive, the usage of steel structure will increase rapidly.

PTH has over 20 years of experience in this industry, and can provide full services to customers’ requirements covering design, manufacturing, logistic, installation, and after sales service.

With the fast growing of manufacturing industry, large steel structure is very much in demand. The unique advantages are high strength, capable of large span, environmental, seismic resistance etc. Its common applications are factory, warehouses, public buildings and other special application.

prefabricated homes are about 30% faster than traditional construction methods

China prefabricated homes are an industrialized production method for building a house. It is a house that is partially prefabricated in the factory and then transported to the construction site to assemble the components through reliable connection. It is built in Europe, America and Japan. It is called industrialized residential or industrialized residential. The difference in the “assembly room” is that some parts are prefabricated, and the construction site is also poured like a traditional building. It is not an imaginary “building block”.

According to current production scales, prefabricated homes are about 30% faster than traditional construction methods. The safety of prefabricated homes China are completely okay, because prefabricated stairs, façades, etc. are transported to the construction site, and reinforced concrete is also required to be lapped, not simply connected. Each floor has a steel bar running through it, and the structure of the house is very strong. Prefabricated homes have higher component accuracy than traditionally constructed homes. It can maximize the quality of the wall cracking, leakage and other common problems, and improve the overall safety level, fire resistance and durability of the house.

Prefabricated homes are more energy-efficient and environmentally friendly during the use of the house, such as the new insulation layer for better insulation. If household metering is implemented, the temperature in the prefabricated homes is higher at the same temperature, and the head of the household can consider lowering the heating temperature, saving heating costs, and reducing energy use.

Prefabricated homes China are good for energy saving and environmental protection. Through factory production and on-site assembly construction, construction waste and construction sewage can be greatly reduced, construction noise can be reduced, harmful gases and dust emissions can be reduced, and on-site construction and management personnel can be reduced.

If you need a temporary home, then prefabricated homes China are definitely a great choice. It is built fast, easy to use, and most importantly it can be moved.

The building materials and design of prefabricated buildings need fire prevention and earthquake resistance

In a standing-room-only presentation at the Malibu Library Sunday, local residents and fire victims flocked to hear presentations from three LA-area prefabricated homes manufacturers. Prefabricated homes are built in sections in large warehouse-like facilities, eliminating weather damage or delays, then moved to the site and assembled. They’ve come a long way from the “manufactured homes” of yesteryear and the industry has evolved to the point where their homes look the same as homes built on-site.

The “prefab” or “modular” option is apparently being looked at seriously by a number of Malibu’s fire burnouts, not only as primary residences, but as temporary residences and accessory dwelling units, or “granny flats,” as they’re sometimes called. Some of the biggest reasons for their appeal are that prefabs cost less and are faster to build than an on-site construction, but have comparable quality.

The industry reps say that one of the first steps someone should take when considering a prefab is to request a site survey to make sure the property and the road leading up to it will facilitate the structure. The modules built by some companies are 16 feet wide and would need a road at least that wide to be transported to the property. Other companies make housing modules only eight feet wide. All of the companies make units small enough to fit City of Malibu rules for the size of a temporary residence and/or ADU.

The prefab companies all maintain that their building materials and designs are as fireproof as possible. “We use steel frames and bolts, metal siding, roof sprinklers and a continuous membrane across the roof,” one said, “as well as roof designs without eves or overhangs that could let embers in.” “Any new homes, including ours, are going to be a thousand times more fire resistant than anything built in the 1940s or 50s,” one added, “just because of all the new regulations.”

In addition, they say their homes have to meet California seismic standards for earthquakes, and that “being quake-proof also means they’re wind-proof.”

In response to questions about cost, some give a ballpark price of about $250/square foot, and costs are quoted up front. Most companies will allow buyers to tour their factories and see their homes being built. Some are willing to competitively bid the pre-delivery site work.

Four Green Warehousing Features of Prefabricated Warehouses

China's Green Warehousing and Distribution Conference was successfully held in Chongqing today. As an enterprise that actively acts for green warehousing, Putian Integrated Housing has many years of practical experience in the construction of green warehousing space, and its Prefab Warehouses solution also has its own characteristics in terms of green environmental protection:

1. Land conservation. Prefabricated warehouse solution can flexibly utilize idle land in the park and idle land that cannot build fixed buildings for the construction of movable storage space. Through the innovative fixing method with the ground, the foundation can be repeatedly installed and disassembled without any treatment. And its internal space has no redundant upright post, which is 100% space utilization; When in use, free land can be fully utilized for installation; when not needed, the device can be quickly disassembled without damaging the ground; and after disassembly, the device can be transported to a new site for re - installation. All of these have greatly improved the utilization rate of idle land and in essence saved land.

2. Save materials. The prefabricated warehouse solution uses a modular combined structure of units and uses very little material. Under the condition of the same size and area, the material consumption is only 40% - 50% of that of traditional steel structures. At the same time, the scheme has the characteristics of high salvage value recycling, and the main frame structure material can be 100% recycled for reuse.

3. Energy conservation. Prefabricated warehouse solutions make full use of renewable energy to reduce energy consumption. Its roof and four-sided wall have three design schemes of full light transmission, semi-light transmission and partial light transmission, all of which can be designed as required.

4. No pollution. The prefabricated warehouse mainly uses aluminum alloy profiles and PVC membrane materials, which are environmentally friendly and recyclable materials. In the production of prefabricated parts, no waste gas, waste water and waste are generated, and the cut materials are all recycled by recycling factories. In addition, in the project installation and construction site, directly connecting and installing prefabricated components will not cause dust, waste and other pollution.

As a powerful supplement to the traditional warehouse, the fabricated warehouse has the above unique green environmental protection advantages. What is more valuable is that these green advantages not increase the input cost of the enterprise, but can bring good economic benefits to the enterprise.

China's Steel Structure Residence Must Develop Vigorously

Prefabricated houses, i.e. houses built in prefab housing, use industrialized production methods. Some or all components of houses are prefabricated in factories and then transported to the construction site. Houses built by assembling components through reliable connection methods are called Residential industrialization or industrialized houses in Europe, America and Japan. Prefabricated houses are mainly divided into three development modes: prefabricated reinforced concrete structure, prefabricated lightweight steel structure and prefabricated Container house.

Today, let's talk about prefabricated steel structure housing.

Steel structures in advanced foreign countries have exceeded 50%, Japan has reached 70%, while in China less than 10%, more than 90% are still RC structures. China's steel structure residential buildings must be vigorously developed. Chinese real estate developers should be able to see business opportunities from it. The key lies in how to organize industrial production.

Industrialized production will surely promote new growth points in China's economic development. If the development of RC structure makes the construction from manual to mechanized, then the application of steel structure will certainly modernize the residential construction.

Light gauge steel house has the characteristics of light weight, large span, good wind and earthquake resistance, excellent thermal insulation, sound insulation and other indicators. It is a green building system with high efficiency, energy saving, environmental protection and in line with the policy of sustainable development.

It is suitable for villas, multi-storey houses, holiday villages, clubs and other civil buildings as well as building floors, flat roofs, light internal partitions and so on. Can be pre-assembled, the wall includes pre-installed exterior wall enclosure, insulation and windows. The roof truss system can also be provided to developers in the form of pre-assembly, which greatly shortens the construction period compared with traditional construction methods.

Prefabrication is constantly improving for buildings

Prefabrication is not a new concept for architecture, but its use can be said to be continuously improving. The use of prefabricated materials can reduce costs while being more sustainable and efficient. However, in order to achieve this, there must be a clear construction process, respecting the architectural intent and combining the whole structure with the architectural facilities. In this way, the work can be completed in the shortest time, and labor and maintenance costs and waste of materials are reduced.

The following five selected projects use prefabricated materials and demonstrate their benefits to creative design strategies. Read on to learn how architects describe their prefabricated projects.

1.Nova Casa Triângulo / Metro Arquitetos Associados

"Designers chose more efficient building materials in the detail deepening stage because prefabricated building materials do not need to be over-processed in the construction process. PC boards and cement boards applied in building facades and main exhibition areas, as well as steel frames covering ceilings, are examples of prefabricated materials. "

2.#48 Zero Energia / Skilpod + UAU Collective

"After building a large number of prototype buildings (steel structure, wood structure, battery building, steel wood, etc.), they began to use CLT: cross composite wood. CLT is not cheap, but it is a good construction method for our application: high strength, good thermal performance, fast production, almost no thermal bridge, convenient transportation, stable construction (such as crane lifting), and it has been used in very beautiful interior decoration (so it does not need to use mortar that is easy to crack). "

3.Refúgio em Finca Aguy / MAPA

"Prefabricated houses are produced in a controlled environment and are elaborately made. They produce in factories and are taken to their final destination. "

4.Casa de Madeira / Estudio Borrachia

"This house not only provides a timely and specific response to the design and construction problems, but also studies the verification of a series of studies on low cost and rapid implementation of system prefabrication over the years."

5.Estúdio Madalena / Apiacás Arquitetos

"A limited budget is a prerequisite for this project. To this end, we followed the construction method of the office recently working in the same community: "the world bar is constructed of metal structure and precast concrete panels, which speeds up the execution time. Our office developed this prefabricated system in order to subvert the use of materials widely used in Brazil. Concrete, which is usually used for concrete slabs, is used here for building sealing. A pair of slabs can form a variable height cavity wall 25cm wide. "
