Waterproof connecting structure of deformation joint of building roof

Abstract

The invention discloses a waterproof connecting structure of a deformation joint of a building roof. The waterproof connecting structure comprises a waterproof roll layer, a fireproof rock wool layer,a waterproof elastic material connecting band, an elastic rubber band, the deformation joint and a waterproof aluminum plate. The deformation joint is arranged between a first concrete wall body anda second concrete wall body. The fireproof rock wool layer, the waterproof roll layer and the waterproof aluminum plate are sequentially laid on the top of the deformation joint from bottom to top. Prefabricated grooves are formed in the first concrete wall body and the second concrete wall body on the two sides of the deformation joint, pre-embedded anchor cables are arranged in the first concrete wall body and the second concrete wall body, locking heads are fixed into the pre-embedded anchor cables and connected with locking plates, the locking plates are arranged in the prefabricated grooves, bolt holes are formed in the locking plates, connecting bolts penetrate into the bolt holes, and the connecting bolts sequentially penetrate through clamping arms, the bolt holes of the locking plates, cushion plates and U-shaped glands from top to bottom to be connected with nuts. Assembly and disassembly are convenient, mounting and replacing of the fireproof elastic material connecting bandor the elastic rubber band are convenient, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a waterproof connection structure for building roof deformation joints. Background technique [0002] Today's construction projects are getting bigger and bigger, and their shapes are becoming more and more complex and changeable. This trend makes construction projects need to set up various deformation joints, and the width of the joints is also increasing. The treatment of the waterproof layer at the deformation joint should naturally meet the requirements of expansion and deformation, so as to avoid cracking and damage. [0003] In the past, the waterproofing treatment of building deformation joints was complicated in construction, with many procedures, complicated measures for fixing water-stopping and waterproof materials, and many vertical and horizontal joints of various materials, making it difficult to control the construction quality. Even if the designe...

Problems solved by technology

[0003] In the past, the waterproofing treatment method at the deformation joints of the building was complicated in construction, with many processes, the fixing measures of water-stopping and waterproofing materials were complicated, and there were many joints of various materials in the vertical and horizontal directions, and the construction quality was difficult to control

Even if the designed waterproof structure is perfect, but the construction level is uneven, facing the complex structure and the construction level limit of workers, the waterproof structure of the deformation joints cannot meet the design requirements and cause water leakage; when the joint width is 50mm, only Water belts, waterproof membranes or caulking ointment can still meet the waterproof requirements, but when the seam width is large, even reaching ≥100mm, these traditional waterproof construction methods for building deformation joints are difficult to effectively meet the waterproof requirements of building deformation joints

The deformation seam is easy to tear and its fixation is inconvenient, and its firmness is poor. Secondly, the waterproof membrane is inconvenient to replace and difficult to disassemble.
