The steel structure prefabricated houses is a kind of light steel structure as the frame, color steel composite color steel sandwich panel as the raw material of the bent structure, and the standard displacement index product series for the interior space design and composition, and the prefabricated components are connected by bolts , The composite wall panel adopts drill tail nails, a newly defined ecological environment protection cost-effective mobile home. It can be assembled and disassembled in a cost-effective manner, completing the practicability and standardization of temporary buildings, creating a core value of engineering construction that is green, environmentally friendly, convenient, fast and efficient, and making temporary houses enter an integrated design and development, integrated production and processing , supporting supply, available supply and fixed product fields that can be used for multiple turnover funds.
Generally, it is not easy for prefabricated houses to have the problem of ventilation, but with the extension of use time, prefabricated houses will also have this or that situation. Movable plank houses have been more and more recognized in the contemporary era, and the applied rooms have also greatly increased the scope and frequency of use.
Solution for air and water leakage of prefabricated houses:
1. The exposed part of the bolts at the top of the prefabricated houses should be first applied with a waterproof rubber brush for many times.
2. The movable roof connector shall be filled with suture sealant first, and then the joints on both sides shall be painted with waterproof glue, and then the non-woven fabric or glass fiber yarn shall be stuck to the waterproof glue above, and finally the waterproof glue shall be brushed on the cloth for 3 or 4 times.
3. Repair method for the thin seam of the prefabricated houses: paint the interface of the movable room with special color moisture-proof plastic for steel frame structure, non-woven fabric paste, and then apply glue on the non-woven fabric brush.
4. A big repair method for the joints of the activity room: fill the joints to facilitate the application of high polymer rigid waterproof architectural coating, and then apply waterproof glue. The glue needs to be thick and sticky, and non-woven fabrics are also needed. At the same time, waterproof paint is repeatedly applied on the edges.
The key is that according to the location difference of air and water leakage of each prefabricated houses, each location has a different solution.
