Prefabricated houses can be seen in many commercial areas because of their movable and disassembled features, so what is the difference between a container and a
Prefabricated House? Come with us to find out!
The Difference Between Containers and Prefabricated Houses
1. Production and construction
The container
Mobile Home has standard specifications. It combines steel and new plates. All parts are produced in the factory and transported to the site for direct hoisting. The installation is simple and fast, the stability is strong, and it is convenient to disassemble and can be used many times. However, traditional prefabricated houses are welded and assembled after transporting materials to the site according to the needs of consumers, which takes a long time and has low stability. It needs to be mixed with concrete to achieve standard strength, and cannot be used after disassembly.
Second, the living performance
Since the materials of the container mobile home are all environmentally friendly and pollution-free, and have the effect of fire prevention, heat preservation and heat insulation, the design is high in the middle and low around, so there will be no rain leakage. Due to its variety of standard independent specifications and styles, the scope of use is no longer limited to construction sites. Many commercial buildings and temporary residences have begun to use container mobile homes. However, due to the limitation of materials used, the traditional prefabricated houses have poor fireproof performance and poor thermal insulation, and the experience of living in summer is even worse. After disassembly, they cannot be reused, and the waste is serious.
What is the standard size of the prefabricated house?
The standard sizes of prefabricated houses on the construction site are: 2.7m*6m, 2.7m*7.2m, 3.6m*6m, 3.6m*7.2m, 3.6m*8.4m. Specifically, the size of the mobile room is formulated according to the actual situation such as the site and the number of construction personnel.
What materials are used for the movable board room?
1. Cement movable room
It is suitable for various construction sites as office migrant worker dormitories. It can also be used for flat roof and storey, various warehouses, etc. The wall is made of double-layer steel wire mesh, lightweight thermal insulation material and high-grade cement prefabricated composite board, thermal insulation, heat insulation, light weight, high strength, machine-made cement tiles for the top surface, colored water brushed surface for the external wall surface, and High-grade plastic pattern wallpaper decoration interior adopts aluminum alloy keel gypsum board ceiling, beautiful and novel, convenient and fast for transportation and installation, steel windows, steel doors, glass, locks, and complete supporting facilities.
2. Phosphorous magnesium soil activity room
Phospho-magnesia prefabricated house is the cheapest, lightest and easiest-to-build simple light-weight prefabricated house in the prefabricated house market. It has the unique effects of waterproof, fireproof, shockproof and anti-corrosion. The board is made of polystyrene core, which can fully achieve the effect of heat preservation and heat insulation. The standard width is 5 meters, the length is 12 meters, and the weight is more than two tons. * Special-shaped rooms can be designed and built according to user requirements. It is suitable for temporary housing of construction units.
3. Prefabricated house with color steel plate
The wall of the prefabricated house with color steel plate adopts the specification and size of the color steel plate cladding polyethylene foam sandwich composite panel products, and the space interval can be determined according to the needs. The service life of Lida prefabricated houses is as long as 10 to 20 years, with thermal insulation, beautiful appearance, and can be used as decorative ceiling treatment indoors.
Mobile room installation steps
step 1
The prefabricated house is similar to building a building. It is best to use reinforced concrete to level the foundation of the surrounding walls and partition walls, or you can use 24-wall bricks to build them. It is relatively strong; Wall panels and door and window frames; then install floor purlins, install stairs, lay floors, and then install a layer up, and then install roof trusses and roof panels; finally install doors and windows, etc., and pull vertical supports. There are sanitary ware, hardware and the like.
step 2
In fact, this is a light steel structure, which is very similar to a heavy steel structure factory building. The hidden project of the prefabricated house refers to the part that will be covered by the next process after the previous process is completed during the construction process. If it is not done well, no matter how beautiful the surface decoration is, it is in vain
step 3
"Concealed works" can be divided into water installation, electrical installation and moisture-proof, waterproof and other projects. Each of these items cannot be ignored. If any link goes wrong, it may cause serious economic losses and even harm personal safety. The construction process and material identification of waterproofing works to avoid unnecessary economic losses and injuries.
Seven technical points of mobile room installation
1. The enclosure panels (roof panels and wall panels) of the prefabricated house should have no obvious deformation or damage; the fixing bolts, waterproof gaskets, metal gaskets, nylon sleeves, etc. are complete, and the connection is reliable; the sealant is complete and effective.
2. The panel of the movable panel house should be installed stably, the cornice should be straight, and the overlapping direction of the panel should be correct and consistent.
3. The installation of the attached wall panels should be correctly arranged and the surface should be flat; the installation of the embedded wall panels should be flat, the upper and lower lap joints should be grooved, the outer panels should be lapped downwards, and the lap length should not be less than 15mm.
4. The electrical wiring in the movable board room should be laid out with PVC pipes (troughs), and the wiring is neat and beautiful; the electrical configuration meets the design requirements; the wiring is not insulated for aging and used for long connections.
5. Fire resistance: The fire distance should meet the design and specification requirements, and the fire exit should be unobstructed; the configuration of fire hydrants and fire extinguishers should meet the design requirements, and the layout should be reasonable; the fire prevention and heat insulation measures for fire places such as kitchens should be effective; If it is lower than 32, combustible materials such as wooden floors should be treated with fire protection.
6. Lightning protection: The lightning protection grounding setting meets the design and specification requirements; the grounding resistance should pass the test.
7. Anti-corrosion: Steel components should be well painted, free of rust, and exposed bolts should be properly protected; anti-corrosion measures in strong corrosive environments meet the design requirements; the surrounding area of the activity room should be well-drained, without water, and no sundries are allowed.
Precautions for installation of activity room
1. Before installing the wall panels, check that the double-check columns and wall beams are installed correctly, firmly and flatly
2. The vertical joints of metal
Sandwich Panel wall panels should be spliced with grooved joints or I-shaped aluminum, and sealant should be installed at the joints.
3. The connection between the metal surface sandwich panel and the ground beam, wall beam or floor truss should be connected by bolts. The horizontal spacing of connecting bolts should not be greater than 500mm (no less than two bolts should be set in the width direction of each plate).
4. The installation of embedded wall panels should be inserted into the grooves on both sides of the column in time when the cold-formed thin-walled steel structure is installed. The connection length should not be less than 15mm.
