Splicing-type heat-preservation waterproof roofing slate, splicing-type heat-preservation waterproof roofing slate composite structure and construction method thereof

Abstract

The invention provides a splicing-type heat-preservation waterproof roofing slate and a composite structure thereof and a construction method. The problem that sealing at combination of adjacent slate bodies of a waterproof heat-preservation composite board and a composite structure thereof is untight is solved, and the traditional construction method is simplified. A roofing slate body is provided with a supporting side end and a lap joint end, a transverse lap-joint eave is provided with a front end extending in an aslant-downward mode, and a boss is arranged at the lower portion of a back end face of a heat-preservation layer; a groove opening formed in the portion, located at the upper portion of the boss at the back end face of the heat-preservation layer of the roofing slate, of the front portion of the composite structure is filled with polyurethane polyfoam. The construction method includes the steps of transverse laying and longitudinal laying; foam filling grooves in the supporting side ends of the slate bodies are filled with polyurethane polyfoam, and the transverse lap-joint eaves at lap-joint side ends of transverse adjacent roofing slates are buckled on waveform fiber tiles at the supporting side ends of the adjacent slate bodies; the traditional construction method is simplified, the waterproof performance is reliable and lasting, the water draining function is powerful, the heat preservation performance and the heat insulating performance are good, the fireproof performance is excellent, damage resistance is high, and the waterproof and heat-preservation effects are obvious.

Description

technical field [0001] The invention relates to a building roof thermal insulation and waterproof structure, in particular to a spliced ​​thermal insulation and waterproof tile board, a spliced ​​thermal insulation and waterproof tile composite structure and a construction method thereof, which are suitable for tiled roofs of sloping houses. Background technique [0002] At present, in the tile roof structure of sloping house buildings, the structure of the hanging tile roof must have the functions of waterproof, heat preservation and fire prevention. The utility model patent of the applicant's patent announcement number 204282652U discloses a corrugated waterproof and heat preservation composite board , its structure includes: the outer surface of the insulation layer body is a corrugated surface formed by a plurality of longitudinal arc-shaped protrusions, the corrugated fiber cement waterproof board is bonded to the corrugated surface, and the crests of the outer surface o...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a spliced ​​thermal insulation and waterproof tile board, a spliced ​​thermal insulation and waterproof tile composite structure and its construction method, which fundamentally solve the problem of the waterproof and thermal insulation composite board and its composite structure on the roof of the existing sloping house building. There are splicing gaps at the junction of adjacent boards, especially the technical problems of frost heaving and poor sealing of the tile roof in the cold northern region. At the same time, it also solves the complicated construction process of laying the thermal insulation and waterproof layer of the existing tile roof, and the joints of the boards are not easy to keep warm The problem of sealing connection further improves the thermal insulation and waterproof effect of the combined structure of the tile roof waterproof and thermal insulation composite board, simplifies the traditional construction method, improves the overall installation and construction efficiency of the roof, and ensures the construction quality
