Problems solved by technology

[0003] The roof panel is a structure exposed to harsh environments, and its requirements are different from those of the floor slab. Due to the use of the roof, the load may change greatly, so the roof structure is required to have a large bearing capacity reserve. The exposure of the roof requires it to have It has good heat preservation and heat insulation performance, and the most basic function of the roof is waterproof. The traditional roof structure is a cast-in-place concrete beam-slab structure, and its bearing capacity has no reserve, and a large overload will cause safety hazards. It is easy to crack and fail under environmental and overload conditions, while flexible waterproofing is easily damaged in the harsh environment of the roof, and its durability is also affected. However, the durability of roof waterproofing or roof waterproofing is a problem in the world

Abstract

The invention discloses a waterproof top cover and a construction method thereof. The waterproof top cover comprises a water stopping edge frame and a waterproof web, wherein the water stopping edge frame is of an annular sealed shape; the waterproof web is arranged at the upper part of the water stopping edge frame. The waterproof web and the water stopping edge frame are made of different waterproof materials. According to the waterproof top cover, a flexible waterproof layer of a concrete hollow web is transferred to a bottom surface of a top plate of a hollow web from the top surface of a foundation, so that a buoyant force is reduced; a core mold which is filled into the web plate is connected with the foundation and extends into the foundation, so that a gripping force of the core mold and lateral resistance of the foundation can be used for resisting the buoyant force, and furthermore, the construction price of a basement bottom plate and a heat-preservation and waterproof concrete web roof panel is reduced and an anti-floating bearing force of a basement is improved; the web of the waterproof top cover and the bottom plate are embedded and connected, so that the web of the waterproof top cover and the bottom plate have a common effect, a bearing capability of a concrete structure is enhanced and an anti-cracking performance of the bottom plate can be greatly improved, and furthermore, a self-waterproof performance of the structure is improved and a waterproof effect is good.

Description

technical field [0001] The invention relates to a waterproof top cover, in particular to a waterproof top cover for a concrete hollow board and a construction method thereof, belonging to the technical field of building waterproofing. Background technique [0002] The basement floor has anti-floating and waterproof requirements, especially the once-in-a-century buoyancy load and waterproof requirements make the basement floor expensive. Existing technical specifications require the use of rigid concrete structure self-waterproofing and flexible membrane waterproofing for double waterproofing. The use of concrete hollow slab structure can greatly save concrete and reduce steel consumption by increasing the height of the section. However, the traditional waterproofing method is to lay waterproof membranes on the base. The disadvantage is that there are too many joints to leave hidden dangers. The construction of the base form and the binding of steel bars are easy to cause da...
