Description

Technical Field

[0001] This utility model relates to a building engineering technology, and in particular to a flue installation connector and a flue. Background Technology

[0002] Existing building flue installations primarily employ two methods: One method involves manually sealing the junction between the floor slab and the flue with mortar after fixing the flue without any auxiliary components. This is slow, and the lack of working space near the wall makes sealing incomplete. Furthermore, the mortar itself is prone to cracking, leading to smoke leakage at the joint. The other method uses metal connectors for flue connections. These connectors consist of two steel bars that penetrate the metal connector, with their ends protruding from the connector. Installation requires drilling holes in the concrete wall to insert the steel bars, which then support the weight of the flue. This method is inconvenient. Gaps exist between the steel bars and the through-holes in the connector, and after installation, the through-holes cannot be properly sealed by the filler material, resulting in smoke leakage. Additionally, the steel bars on both sides of the connector significantly reduce the depth to which the flue extends into the groove, potentially leading to poor sealing between the flue and the connector, further contributing to smoke leakage. Summary of the Invention

[0003] The purpose of this utility model is to provide a flue installation connector and a flue, and the technical problem to be solved is to facilitate construction and improve the sealing effect.

[0004] To solve the above problems, the present invention adopts the following technical solution: a flue installation connector, including a connector body, the connector body is annular, the frame cross-section of the connector body is H-shaped, and annular first connecting groove and second connecting groove are formed at opposite ends of the connector body, and connecting ears are connected on the outer wall of the connector body.

[0005] Furthermore, the first connecting groove and the second connecting groove are the same size.

[0006] Furthermore, the connecting ears are disposed on the opposite outer walls of the connector body.

[0007] Furthermore, the connector body has a rectangular ring structure.

[0008] Furthermore, the four corners of the first and second connecting grooves located on the side of the inner hole of the connector body are flat angles.

[0009] Furthermore, the wall thickness of the connector body is 3mm.

[0010] Furthermore, the height of the connector body is 100mm.

[0011] Furthermore, two connecting ears are provided on the opposite outer walls of the connector body.

[0012] This utility model also discloses a flue, including a flue pipe body and the aforementioned flue installation connector, wherein the flue pipe body is respectively inserted into a first connecting groove and a second connecting groove to realize the connection between the flue pipe bodies.

[0013] Furthermore, polymer mortar is filled between the first connecting groove, the second connecting groove and the flue pipe body to achieve sealing and fixation between the flue pipe body and the first connecting groove and the second connecting groove.

[0014] Compared with the prior art, this utility model sets the cross-sectional shape of the connector body frame to H-shape, forming annular first and second connecting grooves respectively. An integrally connected connecting ear is provided on the outer wall of the connector body. The connecting ear is set on the outer wall of the connector body, so that there is no occupied space in the first and second connecting grooves, allowing the flue to be fully inserted into the first and second connecting grooves. This makes the connection between the flue and the connector body tighter, improves the sealing effect between the flue and the connector body, and prevents smoke leakage. By setting the connecting ear on the outer wall of the connector body, it is possible to directly fix the connecting ear to the edge of the floor opening during installation without drilling holes in the wall, which is convenient for construction.

[0018] Figure 4 This is a schematic diagram of the pipe connection of this utility model. Figure 2 . Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 and Figure 2As shown, this utility model discloses a flue installation connector, including a connector body 1. The connector body 1 can be made of stainless steel, aluminum alloy or galvanized steel plate. The connector body 1 has a rectangular ring structure. The frame cross-section of the connector body 1 is H-shaped, so that a first connecting groove 2 and a second connecting groove 3 are formed at opposite ends of the connector body 1. The first connecting groove 2 and the second connecting groove 3 have the same depth. A connecting ear 4 is welded on the outer wall of the connector body 1. The connecting ear 4 is made of the same material as the connector body 1.

[0021] like Figure 1 As shown, in one embodiment of this utility model, the connecting ears 4 are provided on the outer walls of opposite sides of the connector body 1, with two connecting ears 4 on each side.

[0022] like Figure 1 As shown, the four corners of the first connecting groove 2 and the second connecting groove 3 located on one side of the inner hole of the connector body 1 are flat angles 7, so as to increase the area of ​​the corner position and thereby further improve the sealing effect at the four corners.

[0023] In this utility model, the wall thickness of the connector body 1 is 3mm; the height of the connector body 1 is 100mm; the depth of the first connecting groove 2 and the second connecting groove 3 is greater than 30mm; the other dimensions can be set according to actual needs; it is necessary to ensure that the width of the first connecting groove 2 and the second connecting groove 3 is greater than the wall thickness of the flue pipe body 5.

[0024] like Figure 3 and Figure 4 As shown, this utility model also discloses a flue, including a flue pipe body 6 and the aforementioned flue installation connector. The flue pipe body 5 is respectively inserted into the first connecting groove 2 and the second connecting groove 3 to achieve the connection between the flue pipe bodies 5. In order to ensure the sealing effect, polymer mortar 6 is filled between the first connecting groove 2, the second connecting groove 3 and the flue pipe body 5 to achieve the sealing and fixing between the flue pipe body 5 and the first connecting groove 2 and the second connecting groove 3.

[0025] In this invention, the ratio of polymer mortar to water is 3:2.

[0026] During installation, after the lower flue pipe 5 is installed, verify the position of the flue pipe to ensure accurate positioning. The upper opening of the flue pipe should be within 20mm below the floor slab surface. Fill the second connecting groove 3 with polymer mortar, with a mortar-to-water ratio of 3:2. Insert the lower end of the connector body into the upper opening of the flue pipe 5, clean up the squeezed-out polymer mortar 6, and verify the position of the connector body. Fill the first connecting groove 2 with polymer mortar, insert the upper flue pipe 5 into the first connecting groove 2 and press it firmly. Use a laser pointer to mark the lines to ensure accurate installation position. Compact and smooth the polymer mortar squeezed out of the first connecting groove 2. Finally, install the formwork, and simultaneously pour the concrete for the hanging hole and the curb.

[0027] This invention can improve the sealing effect between the flue pipe and the connector body, completely solving the common quality problems of flue smoke leakage and backflow, greatly improving the living experience of customers. Since it does not use steel bars for fixing, it avoids drilling operations in the wall and other places, making construction easier.
