A flat roof modular structure

Abstract

The invention discloses a flat roof modular structure, which comprises a structural layer, a leveling layer and parapets arranged around the structural layer, the structural layer is provided with a roof surface layer; the roof surface layer is provided with a waterproof system; the waterproof The system is equipped with a number of protective plates that are compatible with it; the roof surface layer is composed of a leveling layer, and several rows of parallel steel seats are arranged on the leveling layer perpendicular to the direction along the water, and are set between the two steel seats and connected to the steel seats. The insulation layer is formed by occlusal joints. The waterproof system consists of a number of waterproof membrane clamps arranged along the water direction, a wooden board clamped between the two waterproof membrane clamps, a waterproof membrane layer above the wooden board, and buckles. The waterproof membrane clamp and the waterproof membrane layer are composed of a waterproof gland and a detailed node waterproof layer. There are several air outlets on the inner side of the parapet along the water direction; and communicated with the groove on the outside. The other end of the direction is provided with several upper and lower water outlets; the parapet is a reinforced concrete structure.

Description

technical field [0001] The invention relates to a building roof construction technology, in particular to a building flat roof modular structure, which belongs to the building field. Background technique [0002] Roof refers to the surface of the roof of a building, mainly including structural layers, leveling layers, thermal insulation layers, waterproof layers, protective layers, decorative layers, drainage and exhaust systems, and detailed nodes. The parapet refers to the low wall around the roof of the building. In addition to maintaining safety, it will also be closed with waterproof bricks at the lower part to prevent water seepage from the waterproof layer or rainwater from overflowing on the roof. The split joint refers to reducing the total shrinkage value and temperature stress of the large-area rigid waterproof layer, and avoiding the cracking and leakage of the waterproof layer caused by the displacement of the structural layer and the change of temperature and h...

AI Technical Summary

Problems solved by technology

However, although the above method can solve the problem of exhausting the insulation layer or the slope, it will cause the roof to protrude and form many nodes, which is not conducive to the waterproofing of the roof. At the same time, the vent holes are easy to be blocked and damaged.

According to the waterproof type, the roof mainly includes rigid roof and flexible roof. The rigid roof is integrally poured. It is heavy and has low tensile strength. It is easily deformed by external influences, and then cracks will affect the waterproof effect. Finding the leak point will cause inconvenience to maintenance; flexible waterproofing overcomes the shortcomings of rigid waterproofing to a certain extent, but some materials are prone to aging after being exposed to sunlight and ultraviolet rays for a long time, resulting in poor durability and short service life.

In addition, traditional thermal insulation materials and waterproof membranes are difficult to combine, and traditional laying methods require an additional bonding layer, which increases construction costs and processes
