Roofing rigid waterproof layer structure and construction method thereof

Abstract

The present invention relates to a roofing rigid waterproof layer structure and a construction method thereof. A rigid waterproof layer is obtained through processes of surveying and setting out, arranging a dividing strip layer, pouring a bottom layer waterproof layer, laying a waterstop belt layer and pouring an upper layer waterproof layer and the like, and a plurality of dividing joint structures are staggered in the rigid waterproof layer. The roofing rigid waterproof layer structure has the beneficial effects that a dividing joint is separated from external environment by a waterstop belt, and the top of the waterstop belt is provided with the dividing joint and a waterproof coating protective layer; construction progress is accelerated, cost is saved to a certain degree, concrete moulding effect is good, and the surface is flat without ponding cold ponds; and after joint material and waterproof coating are aged and not waterproof, due to the fact that the waterstop belt is disposed and the surface layer dividing joint is relatively shallow, moisture is not easy to leak and can be rapidly evaporated, temperature telescoping deformation of the concrete rigid waterproof layer is satisfied, waterproof performance of the dividing joint is largely enhanced, and service life period of roofing waterproof is prolonged.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a roof rigid waterproof layer structure and a construction method thereof. Background technique [0002] With the development of society, concrete roofs are more and more widely used, and the requirements for roof waterproofing are getting higher and higher. Relevant construction engineering design specifications are generally to prevent damage to the membrane waterproof layer, set up a rigid waterproof layer, and at the same time set up grid joints to adapt to the expansion and deformation of the roof temperature. The traditional method is to clean up the grid lines after pouring the rigid waterproof layer of fine stone concrete, fill in the caulking material, and paste additional waterproof membranes on the surface. The additional waterproof membrane and caulking materials are prone to aging and lose their waterproof effect, resulting in the long-term moistu...

AI Technical Summary

Problems solved by technology

The additional waterproof membrane and caulking materials are prone to aging and lose their waterproof effect, resulting in the waterproof layer (insulation layer) containing water for a long time and unable to discharge

And the additional waterproof membrane is higher than the concrete surface, which is easy to form dust and water on the floor, resulting in poor drainage
