Steps and precautions for installation of movable board room
Nov 13 , 2021
Prefabricated house is a kind of temporary building, which is often used in construction site workers' temporary dormitory offices, factory buildings, field work sites, exhibitions, warehouses, and outposts. It can also be applied to offices, headquarters, dormitories, warehouses, shops, toilets, equipment rooms and various temporary and mobile houses in construction, railway, highway, water conservancy, petroleum, tourism, and military industries.
Mobile room installation steps
1. Digging grooves; 2. Foundations, including brick foundations and concrete foundations; 3. C-shaped steel frame installation; 4. Installation of stairs and walkways; 5. If it is multi-layered, install prefabricated floor slabs; 6. Color steel plate Installation; 7. First floor floor; 8. Door and window installation; 9. Interior decoration.
step 1
The movable board house is similar to building a building. The surroundings and the foundation of the partition wall should be leveled. It is best to use reinforced concrete. You can also use 24-wall bricks to build it. Wall panels and door and window frames; then install floor purlins, install stairs, pave the floor, and then install one floor up, then roof trusses and roof panels; finally install doors and windows, etc., and pull vertical supports. There are sanitary ware, small 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 concealed construction of the mobile house refers to the part that will be covered by the next process after the previous process is completed during the construction process, and all the parts that cannot be inspected after the completion of the construction, the "concealed construction" is the key, if the "concealed construction" If it is not done well, no matter how beautiful the surface is, it is futile.
Step 3
"Hidden engineering" can be divided into water installation, electrical installation, and moisture-proof and waterproof projects. Each of these items cannot be ignored. If any link goes wrong, it may cause serious economic losses and even harm to personal safety. The construction technology and material identification of the waterproof project can avoid unnecessary economic losses and injuries.
Seven technical points for installation of movable room
1. There should be no obvious deformation or damage to the enclosure panels (roofing and wall panels) of the prefabricated house; the fixing bolts, waterproof washers, metal washers, nylon sleeves, etc. are complete, and the connection is reliable; the sealant is complete and effective.
2. Movable board house panels should be installed stably, the cornices should be straight, and the overlapping directions of the panels should be correct and consistent.
3. Attached wall panels should be installed correctly and the surface should be smooth; embedded wall panels should be installed flat, top and bottom lap joints should be tongue-and-groove seams, 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 covered with PVC pipes (slots), and the wiring should be neat and beautiful; the electrical configuration meets the design requirements; the wiring has no insulation aging and extended use.
5. Fire resistance: The fire separation distance should meet the design and specification requirements, and the fire passage should be unobstructed; the configuration of fire hydrants and fire extinguishers should meet the design requirements, and the layout should be reasonable; fire prevention and heat insulation measures should be effective in fire places such as kitchens; the oxygen index of the metal surface sandwich panel should not be Below 32, combustible materials such as wood floors should be fireproofed.
6. Lightning protection: The lightning protection grounding setting meets the design and specification requirements; the grounding resistance should be qualified.
7. Anti-corrosion: steel components should be well painted, no rust, and exposed bolts properly protected; anti-corrosion measures in strong corrosive environments meet design requirements; the surrounding area of the mobile room should be drained without water, and no debris is allowed.
Precautions for installation of movable room
1. Before installing the wall panels, check that the columns and wall beams are installed correctly, firmly and flatly.
2. The vertical splicing of the metal sandwich panel wallboard should adopt tongue-and-groove seams or I-shaped aluminum splicing, and sealant should be installed at the splicing joints.
3. The connection between the metal surface sandwich panel and the ground beam, wall beam or floor sub-truss shall be connected by bolts. The horizontal spacing of the connecting bolts should not be greater than 500mm (no less than two bolts are provided in the width direction of each plate).
4. The embedded wall panel should be installed in the slot on both sides of the column in time when the cold-formed thin-walled steel structure is installed. The upper and lower lap joints of the embedded wall panel should be grooved, and the outer panel should be overlapped downwards. The connecting length should not be less than 15mm.
