Self-waterproof roof drain device

Abstract

According to the self-waterproof roof drain device provided by the utility model, through the structural design of the self-waterproof roof drain device, the hard spring is additionally arranged between the water stop steel sleeve and the drainage vertical pipe, and the dynamic load of rainwater on the drainage vertical pipe is absorbed and buffered by utilizing the characteristics of the hard spring; therefore, the possibility that cracks are generated between the new and old concrete joint surface, the drainage stand pipe and the concrete and between the sealant and the concrete is reduced, and the waterproof capacity and durability of the roof drain are improved. In addition, when the self-waterproof roof drain device is constructed, the leakage risk of later secondary pouring is reduced through direct integrated pre-burying, and therefore the construction quality of the roof roof drain can be effectively improved.

Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a self-waterproof rainwater bucket device. Background Art

[0002] The construction method of the existing roof siphon rainwater bucket is as follows:

[0003] 1) After measuring and laying out, pre-embed the casing (the diameter of the casing is larger than the diameter of the drainage riser) where the rainwater holes need to be reserved, and complete the roof concrete pouring.

[0004] 2) Roughen the inner wall of the reserved hole and the concrete below the projected area of ​​the rain gutter base, and clean the inner wall and surrounding area of ​​the reserved hole.

[0005] 3) After roughening and cleaning the reserved hole, install the siphon drainage main pipe and drainage riser and connect them to the rain gutter base.

[0006] 4) The gap between the drainage riser and the embedded casing is sealed with a hanging formwork, and the sealing material is fine stone concrete or high-strength grouting material.

[0007] 5) Construction of waterproof layer and its additional layer (the waterproof membrane penetrates into the downpipe at the base of the rain gutter).

[0008] 6) Construction of insulation layer.

[0009] 7) Construction of rigid roof layer.

[0010] 8) Install the rigid layer around the downspout and drain outlet.

[0011] The existing practice is to install the siphon drainage pipe and the downspout base, use fine stone concrete or high-strength grouting material to seal the gap between the drainage riser and the embedded casing, fix the horizontal pipe with a bracket, and rigidly connect the drainage riser to the concrete roof. This practice has the following disadvantages:

[0012] 1) Under the long-term dynamic load of rainwater, cracks are likely to occur on the interface between new and old concrete, and between the drainage riser and concrete; 2) Most roof waterproofing membranes are hot-melt connected, and the drainage pipes are rubber tubes. The high temperature at the downspouts can easily cause deformation of the downspouts and cracks at the connection positions, leading to the risk of water seepage and leakage, affecting the construction quality.

[0013] Therefore, for those skilled in the art, how to improve the construction quality of roof rain gutter installation has become a technical problem to be solved urgently in this field. Utility Model Content
