Waterproof heat preservation structure of roof opening node

Abstract

A waterproof heat preservation structure of a roof opening node comprises a roof purline, an opening base, a roof board and a sliding connection piece, wherein the opening base is arranged on the roof purline, the cross section of a base fame is C-shaped, a C-shaped opening is flush with a web plate of a reinforcing purline of the roof opening, one end of the skirt of the base fame is connected to the side, deviating from the C-shaped opening, of the bottom of the base frame, and the other end of the skirt extends in the direction away from the center of the base frame for a certain distance. The roof board is laid on the skirt. The fixing board of the sliding connection piece is connected to the web plate of the reinforcing purline of the roof opening, the top end extends out of the embedding portion located at the bottom of the C-shaped opening, and a hook portion is connected with the top end of the fixing board, bent towards the side close to the skirt for a distance and then is adhered to one side, close to the skirt, of the embedding portion. By means of the structure, the problem that water leakage, cold bridge and poor mutual overall linkage easily occur at the connecting position between a conventional opening base and the roof board is solved.

Description

technical field [0001] The invention relates to the field of building waterproof and thermal insulation, in particular to a waterproof thermal insulation structure of a roof opening node. Background technique [0002] The waterproof and thermal insulation project of the building is an important part of the whole construction project, especially the waterproof and thermal insulation project of the roof, because the roof is directly exposed to the external environment and has to withstand wind, sun and rain, and the waterproof and thermal insulation materials are prone to aging and cracking. Affect the waterproof and thermal insulation performance of the structure. Some buildings with special requirements also need to open holes on the roof, such as fan holes for placing fans, etc. The position of the holes often has hidden dangers of water leakage, and the phenomenon of cold bridges (or thermal bridges) is very likely to occur. [0003] Under normal circumstances, the roof o...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a waterproof and heat-preservation structure of the roof hole joint, through the sliding connection mode of the hole base and the roof purlin, the way of setting the insulation board in the hole base, and the setting of the butt joint between the hole base and the roof panel. The method of base tape solves the problems of water leakage, cold bridge phenomenon and poor overall linkage between the joint between the opening base and the roof panel of the waterproof and thermal insulation structure of the roof opening node.
