Problems solved by technology

However, pasting the sealant strips makes the overlap gap between the boards larger, and it is difficult to apply the sealant in place at many junctions. There are always some gaps left, which cannot solve the problem fundamentally, and it is difficult to meet the steam insulation requirements.
Moreover, the construction efficiency of pasting the sealing strip and applying the sealing paste is low, which affects the construction effect

Abstract

The invention discloses an in-situ composite type heat-insulating steam-insulating building structure for light steel maintenance systems, as well as a relevant construction method. The invention is to solve such problems as high cost and complex construction method and etc in prior arts. The invention of the in-situ composite type heat-insulating steam-insulating building for light steel maintenance systems and the relevant construction method are as follows: 1) Install a lower (internal) board; 2) Perform spray painting foaming polyurethane on lapped butts on a lower (internal) board top face; 3) Lay a polystyrene sheet; 4) Coat spray painted polyurethane on lapped butts between polystyrene sheets and blocks; 5) Lay an upper (internal) board of the light steel maintenance system on the polystyrene sheet. The invention of the in-situ composite type heat-insulating steam-insulating building for light steel maintenance systems and the relevant construction method and structure, can both take heat-insulating effects for light steel maintenance systems (house roofs and wall panels), and more important, prevent steam from spreading to form condensed water to enter the light steel maintenance systems.

Description

technical field [0001] The invention relates to an on-site composite light steel maintenance system thermal insulation and steam insulation building structure and construction method. Background technique [0002] On-site composite light steel maintenance system buildings mainly refer to buildings that use on-site composite profiled steel plates, metal gussets, curtain wall panels, etc. as maintenance facilities such as roofs and walls. [0003] Buildings with on-site composite light-steel maintenance systems in cold regions and indoors with humid and watery environments include buildings such as swimming pools, public bathing buildings, water treatment workshops with insulation, liquid cleaning workshops, and water plants. Under the joint effect of outdoor environment and warm indoor environment, condensed water is likely to be generated due to insufficient heat preservation and steam insulation and immerse into the maintenance system, resulting in moisture and water immers...
