Anti-leakage structure of kitchen flue hanging hole

Abstract

The utility model relates to an anti-leakage structure of a kitchen flue hanging hole. The anti-leakage structure is arranged at the position of the kitchen flue hanging hole. The anti-leakage structure is a pouring layer arranged between the lifting hole opening and the flue. The pouring layer is thicker than the hanging hole and forms a reverse ridge; the pouring layer is made of C30 micro-expansion fine aggregate concrete; a waterproof coating is arranged at the joint of the reverse ridges. Potential quality hazards such as cracking and leakage of the flue hanging hole are effectively avoided. And the used materials are common in a construction site, and are economical and practical.

Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to an anti-leakage structure for a kitchen flue hanging hole. Background Art

[0002] During building construction, the pre-installed hole for the kitchen flue is typically 50-100mm larger than the flue itself, creating a gap between the two. To seal this gap after the finished flue is installed, a hanging hole-casting method is typically required. Since the kitchen is a water-facing room, water pipes are often placed on the roof during daily use, which poses a risk of leakage after long-term use. Therefore, using conventional hanging hole methods to seal the gap between the finished flue and the pre-installed hole can easily lead to cracking and leakage, a potential quality risk. Utility Model Content

[0003] The utility model aims to overcome the defects of the prior art and provide an anti-leakage structure for a kitchen flue hanging hole, thereby solving the quality risks such as cracking and leakage of the flue hanging hole.

[0004] In order to solve the above technical problems, the utility model is achieved as follows:

[0005] A leakage-proof structure for a kitchen flue hanging hole is characterized in that the leakage-proof structure is arranged at the kitchen flue hanging hole.

[0006] The anti-leakage structure of the kitchen flue hanging hole is characterized in that the anti-leakage structure is a casting layer arranged between the hanging hole and the flue.

[0007] The anti-leakage structure of the kitchen flue hanging hole is characterized in that the thickness of the casting layer is higher than the hanging hole and forms an anti-ridge.

[0008] The anti-leakage structure of the kitchen flue hanging hole is characterized in that the casting layer is C30 slightly expanded fine stone concrete.

[0009] The anti-leakage structure of the kitchen flue hanging hole is characterized in that a waterproof coating is provided at the anti-ridge joint.

[0010] The beneficial effect of the present invention is: it can be seen from the above technical scheme that the present application provides a leakage-proof structure for a kitchen flue hanging hole. The leakage-proof structure of the flue hanging hole in the present application mainly consists of three parts: pouring concrete for the first-floor hanging hole, integral pouring of the slab top and the concrete counter-ridge, and brushing of waterproof coating on the joints.

[0011] The hanging hole is poured in two layers. The first pouring is two-thirds of the slab thickness to avoid pouring too thick at one time and causing cracks due to shrinkage during the hardening and solidification of the concrete.

[0012] The second hanging hole features an integral counter-slope structure, with the counter-slope rising 5cm above the finished building surface. The counter-slope and slab top concrete were poured simultaneously, resulting in fewer joints, improved integrity, and resistance to cracking. Furthermore, the counter-slope, which is 5cm above the finished building surface, effectively blocks groundwater infiltration.

[0013] Apply waterproof paint within 150mm of the joints between the countersill and the structural floor, and between the countersill and the flue to prevent water from accumulating at the joints and causing leakage.

[0014] Therefore, the adoption of this structure can effectively avoid quality risks such as cracking and leakage of the flue hanging hole. Moreover, the materials used are common on the construction site and are economical and practical. BRIEF DESCRIPTION OF THE DRAWINGS
