Description

Technical Field

[0001] The utility model relates to an anti-leakage structure at the root of a kitchen flue in a high-rise residential building, belonging to the technical field of smoke exhaust equipment. Background Art

[0002] High-rise residential buildings are a manifestation of the concentration of land resources, which are allocated to different floors by different families. It has one or more vertical chimneys reserved inside, and a flue connected to the chimney is preset in each family. Since the prefabricated concrete flue is directly exposed to oil smoke and water vapor, the inner wall of the flue is obviously aged and corroded, especially the root of the flue, which often needs to be treated with anti-leakage.

[0003] Chinese patent CN108035513A discloses a structure and method for preventing leakage at the root of a finished exhaust duct. The root of the finished exhaust duct is sleeved on the outside of an iron ring, and an anti-corrosion and anti-rust layer is provided at the root of the finished exhaust duct, which has a better effect on treating the common problem of root leakage. However, the iron ring itself has poor elasticity and is directly facing the flue gas. They are subjected to more frequent hot and cold changes than the wall, and are prone to gaps with the root of the flue due to thermal expansion and contraction, resulting in a weak self-compensation ability of the anti-leakage structure at the root of the flue. For this reason, we propose an anti-leakage structure for the root of the kitchen flue in a high-rise residential building. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model provides a high-rise residential kitchen smoke duct root anti-leakage structure, which has automatic compensation capability and can seal the rupture position when a gap is generated.

[0005] The technical solution of the utility model is as follows:

[0006] A high-rise residential kitchen flue root anti-leakage structure comprises an alloy square tube, which is installed inside the flue, the end of the alloy square tube extends out of the root of the flue, an elastic layer is sleeved on the outer side of the alloy square tube extending out of the root of the flue, the flue is fixed outside the alloy square tube and the elastic layer is squeezed, and the gap between the root of the flue and the alloy square tube is filled by the elastic layer, the elastic layer comprises a polyurethane ring and a rubber ring which are arranged in sequence from the inside to the outside, the polyurethane ring and the rubber ring are fixed to the root of the flue, two cavities are spaced apart inside the polyurethane ring, and a first glue liquid and a second glue liquid are respectively arranged inside the two cavities.

[0007] Wherein, the upper edge and the lower edge of the rubber ring are both fixed with a limiting ring connected to the alloy square tube.

[0008] The limiting ring located at the upper edge of the rubber ring is fixedly connected to the alloy square tube, and a plurality of elastic ropes are fixed between the sides of the two limiting rings that are close to each other.

[0009] Wherein, a plastic ring is fixed on the outside of at least one limiting ring, and the plastic ring is fixedly connected to the rubber ring.

[0010] Among them, a number of steel wire rings are inserted inside the polyurethane ring, and the steel wire rings are all sleeved on the outside of the alloy square tube to form an annular skeleton.

[0011] Among them, a plurality of supporting angle plates are fixed at intervals at the position of the limiting ring below the rubber ring, and the supporting angle plates and the alloy square tube are fixedly connected.

[0012] The first adhesive is liquid epoxy adhesive, and the second adhesive is liquid acrylate adhesive.

[0013] The utility model has the following beneficial effects:

[0014] The utility model can form a leakage-proof structure with self-compensation capability at the root of the kitchen flue of a high-rise residential building, wherein each time the elastic layer only flows out the AB glue from the aging and ruptured position, and the AB glue is oxidized and hardened in contact with the air, and the ruptured position is sealed, so that most of the AB glue remains in the elastic layer and can flow out in multiple times, having several self-compensation capabilities.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] See also Figures 1 to 4 , the utility model provides a technical solution:

[0023] A high-rise residential kitchen flue root anti-leakage structure comprises an alloy square tube 1, the outer side of the alloy square tube 1 is sequentially sleeved with a polyurethane ring 2 and a rubber ring 3 from the inside to the outside, the rubber ring 3 is a "]" shape, the polyurethane ring 2 is wrapped inside the rubber ring 3, the polyurethane ring 2 is separated into two cavities 4, the two cavities 4 are respectively provided with a first glue 5 and a second glue 6, the first glue 5 can be selected from liquid epoxy glue, the second glue 6 can be selected from liquid acrylic glue, so that the two can form an AB glue reaction for bonding after contact, the two edges of the rubber ring 3 are respectively rolled along the outside of the rubber ring 3 toward the alloy square tube 1, during the construction of the high-rise residential building, The alloy square tube 1 is fixed to the steel keel by welding, and a part of it is exposed. The polyurethane ring 2 and the rubber ring 3 are sleeved on the outside of the alloy square tube 1 until they are aligned with the root of the flue and then fixed. In this way, the polyurethane ring 2, the rubber ring 3, the first glue 5 and the second glue 6 form an elastic layer. After the flue is fixed on the outside of the alloy square tube 1, the elastic layer is squeezed to fill the gap between the root of the flue and the alloy square tube 1. After the elastic layer is ruptured due to aging due to thermal expansion and contraction, the first glue 5 and the second glue 6 overflow and are distributed in the gap, and contact each other to cause AB glue reaction and hardening, and the AB glue flows out to bond the gap to form a self-compensating anti-leakage structure.

[0024] Each time, only the AB glue flows out from the aging and cracked position of the elastic layer. At this time, the AB glue oxidizes and hardens in contact with the air, and will seal the cracked position, so that most of the AB glue remains in the elastic layer and can flow out in multiple times, with several self-compensation capabilities.

[0025] like Figure 2 and Figure 3 As shown, both edges of the rubber ring 3 are fixed with limiting rings 7 connected to the alloy square tube 1. Specifically, the limiting ring 7 is L-shaped, covering the two edges of the "]"-shaped rubber ring 3, limiting the rubber ring 3 from the top and bottom respectively, providing stable support and preventing the elastic layer from detaching from the root of the flue.

[0026] like Figure 1 and Figure 4 As shown, a limiting ring 7 is fixedly connected to the alloy square tube 1 and a plurality of elastic ropes 8 are fixed between the side close to the other limiting ring 7. The elastic ropes 8 can be purchased from high-temperature resistant rubber bands on the market. The two limiting rings 7 are pulled toward the middle by the elastic ropes 8 to squeeze the elastic layer and deform the elastic layer toward both sides to horizontally fill the gap between the root of the flue and the alloy square tube 1.

[0027] like Figure 1 and Figure 4 As shown, a plastic ring 10 is fixed to the outside of at least one limiting ring 7, and the plastic ring 10 is fixedly connected to the rubber ring 3, thereby increasing the connection area between the limiting ring 7 and the rubber ring 3 as a fulcrum and improving the stability of the two limiting rings 7 supporting the elastic layer.

[0028] like Figure 1 and Figure 4 As shown, a plurality of steel wire rings 9 are inserted inside the polyurethane ring 2, and the steel wire rings 9 are all sleeved outside the alloy square tube 1 to form an annular skeleton, which supports the inside of the polyurethane ring 2 to reduce the upward or downward deformation of the elastic layer.

[0029] like Figure 3 and Figure 4 As shown, a plurality of supporting angle plates 11 are fixed at intervals at the position of the limit ring 7 below the rubber ring 3. The supporting angle plates 11 and the alloy square tube 1 are fixedly connected to support the limit ring 7 at multiple points upward, so that the two limit rings 7 and the elastic layer can be stably suspended outside the alloy square tube 1.

[0030] The working principle of the anti-leakage structure at the root of the kitchen flue of the high-rise residential building is as follows:

[0031] During the construction of high-rise residential buildings, the alloy square tube 1 can be fixed to the steel keel, such as by welding, and a part of it is exposed. The polyurethane ring 2 and the rubber ring 3 are sleeved on the outside of the alloy square tube 1 until they are aligned with the root of the flue and then fixed. In this way, the polyurethane ring 2, the rubber ring 3, the first glue 5 and the second glue 6 form an elastic layer. After the flue is fixed on the outside of the alloy square tube 1, the elastic layer is squeezed, and the gap between the root of the flue and the alloy square tube 1 is filled with the elastic layer. After the elastic layer is aging and ruptured due to thermal expansion and contraction, the first glue 5 and the second glue 6 overflow and can be distributed in the gap, and contact each other to cause AB glue reaction and hardening, and the AB glue flows out to bond the gap, forming a self-compensating anti-leakage structure.

[0032] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
