Description

Technical Field

[0001] The utility model relates to the technical field of roof waterproofing of construction projects, in particular to a composite structure of a roof waterproofing project. Background Art

[0002] In construction projects, the roof is the uppermost covering and load-bearing structure of a house. One of its most important functions is to shelter from wind and rain. In most buildings, pipes often need to extend out of the roof, and cracks are prone to occur between the pipes and the roof, leading to problems such as water seepage. Therefore, waterproofing of the pipe area is particularly important. During the existing roof waterproofing construction, the waterproof membrane is wrapped and pasted on the surface of the pipe. Since it is exposed to the outdoors and is affected by temperature changes, rain, sunlight and other environmental factors for a long time, gaps are easily generated between them, causing rainwater to leak from the gap between the pipe and the waterproof membrane into the house, polluting the environment and causing the waterproof function to fail.

[0003] For example, a prior art Chinese utility model patent (CN208220027U) discloses a pipe-through-roof waterproofing structure, comprising a roof, a sleeve disposed on the roof top, a fixing flange extending from the outer circumference of the sleeve, the fixing flange abutting the roof, a leveling layer laid on the roof, the fixing flange located within the leveling layer, an insulation layer and a roll waterproofing layer sequentially laid on the side of the leveling layer facing away from the roof and on the outer wall of the sleeve, an anti-cracking layer, a reinforcement layer, and a topcoat layer sequentially disposed above the roll waterproofing layer located on the roof; a pipe passing through the sleeve, and a curved metal cover plate fixed to the pipe. This utility model solves the problem of leakage at the pipe-through-roof location, thereby improving the waterproofing performance of the roofing system.

[0004] However, the existing technology has the following defects: under the influence of long-term rain, sunlight and other environmental factors, the curved metal cover fixed on the pipeline will age and the sealing effect will decrease, and rainwater leakage may still occur at the joints.

[0005] Based on this, a roof waterproofing engineering composite structure is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

[0009] On the basis of the above technical solutions, the present invention also provides the following optional technical solutions:

[0010] In an optional solution: the waterproof mechanism includes a connecting pipe, the inner side of which is provided with a downward-opening slot, the upper port of the pipe is fixedly connected to the slot, and the lower end of the connecting pipe is provided with a shield, which is located on the periphery of the water-stop sleeve.

[0011] In an optional solution, a fixing hole is provided on the inner side of the connecting pipe, and a connecting screw is rotated in the fixing hole.

[0012] In an optional solution, a sealant is provided on one end of the thermal insulation layer and the waterproof roll layer located on the outer surface of the water-stop casing.

[0013] In an optional solution, a circular arc platform is provided at the inner corner where the sleeve intersects with the leveling layer.

[0014] In an optional solution, an additional waterproof layer is provided between the thermal insulation layer and the leveling layer and on the outer wall of the casing.

[0015] In an optional solution, the inner upper surface of the connecting pipe has the same diameter as the inner surface of the pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The utility model fixes the connecting pipe at the upper port of the pipeline through a slot, and a shield is provided at the lower end of the connecting pipe to protect the joints of the water-stop sleeve, the thermal insulation layer and the waterproofing layer in the middle. The integrated design does not worry about the generation of gaps and water leakage, thereby better achieving the waterproofing of the roof; the inner upper surface of the connecting pipe has the same diameter as the inner surface of the pipeline, which does not affect the subsequent use of the pipeline.
