Method for maintaining profiled steel sheet roofing

Abstract

The invention discloses a method for maintaining the profiled steel sheet roofing, comprising the following steps of: (1) closing and repairing seepage parts; (2) fixing a special bracket support seat and arranging a support seat at the position above a wave trough purline of the traditional profiled steel sheet; (3) sticking a temperature-insulating material and attaching the temperature-insulating material to the upper surface of the temperature-insulating material according to the wave shape of the temperature-insulating material to form a heat-insulating layer; (4) fixing the special bracket and brackets among sheets; and (5) overlapping and fixing novel profiled steel sheets with the same sheet type; covering the novel profiled steel sheets with the same sheet type as the traditional profiled steel sheet above the special bracket and brackets among the sheets; and after finishing the fixation, closing all fixed nodes by using a sealing material. The invention improves the heat resistance of the traditional profiled steel sheet, improves the condensation phenomenon at the bottom of the traditional profiled steel sheet and reduces the continuous corrosion of the traditional profiled steel sheet; meanwhile, by overlapping a novel layer and an old layer to construct the stress, the strength of the roofing of the respiring area can be improved, thereby the aim of repairing and reinforcing the roofing in a state without stopping production can be achieved.

Description

technical field [0001] The invention relates to a roof maintenance method, which is particularly suitable for the profiled steel roof maintenance method of a large heavy industrial factory building where condensation occurs. Background technique [0002] At present, profiled steel plate roofs are widely used because of their advantages of convenient construction and low cost, especially for industrial factory roofs. The normal service life of the profiled steel plate itself is about 10 to 15 years, but the single-layer roof without thermal insulation measures will produce condensation when it is used under the condition of steam or high humidity. According to engineering practice, this single-layer profiled steel plate If the roof is used for about 8 years, there will be large-scale regional corrosion and local perforation. The protection function of the roof will fail due to perforation. [0003] For the profiled steel plate roof under the above conditions, there are three...

Problems solved by technology

The main problems in the actual use of these methods are: the first method will cause the adsorption of water vapor or rainwater between the two layers of the board, resulting in accelerated corrosion, and the actual effect is not good; the disadvantage of the second method is that the waterproof material is prone to aging. , roof cleaning maintenance or engineering defects and damage, resulting in rainwater adsorption and leakage

The first and second methods above did not solve the problem of condensation on the roof, nor did they solve the safety problem after the roof was corroded.

The third method can solve the corrosion problem very well. If the composite thermal insulation roof construction method in the current public standard atlas is used when updating the roof, the condensation problem can be solved, but it is necessary to replace new panels or install steel wire mesh during construction to stop production. In essence, it is a new roof, which does not belong to the maintenance category of the existing roof

These patents are only applicable to new construction or large-scale roof replacement and renovation projects, and cannot solve the problems of condensation adsorption, corrosion, perforation and strength weakening of existing roofs, and cannot utilize existing structures and materials based on the principle of resource conservation. It is also difficult to construct existing buildings under non-stop production conditions, and these are the problems to be solved by the present invention
