Description

Technical Field

[0001] This utility model belongs to the field of building engineering, and specifically relates to a residential flue sealing device. Background Technology

[0002] In residential building construction, sealing the junction of the flue and the floor slab is a crucial step in preventing leakage. However, traditional methods commonly use temporary wooden supports or on-site welded formwork, which suffers from unstable support. Because the flue is located in a confined corner space, the working area is limited, and traditional support methods make it difficult to precisely adjust the height and angle of the formwork. This results in a loose fit between the formwork and the flue / floor slab, easily forming gaps that can lead to grout leakage and water seepage during concrete pouring. Furthermore, the lack of rigid connection in wooden or temporarily welded support systems makes them prone to overturning under the lateral pressure of concrete, posing a safety hazard. In addition, construction relies heavily on manual experience, leading to inconsistent workmanship and quality issues such as formwork misalignment and unevenness. Existing adjustable formwork devices are complex in structure, have poor adaptability, are difficult to use with flues of different sizes, and have low reusability, increasing construction costs.

[0016] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0017] like Figures 1-3 As shown, a residential flue sealing device includes a wall 1, a flue 2, a floor slab 3, and a template support device 4 for sealing; the flue 2 is installed at the corner between the wall 1 and the floor slab 3; the template support device 4 for sealing is provided between the flue 2 and the floor slab 3; the template support device 4 includes an L-shaped metal template 401, an adjustable support component 402, a wooden template 403, and an adjustable support component 404;

[0018] like Figures 1-4 As shown, an adjustable support component 402 is fixedly connected to the bottom of the midpoint where the two right-angled sides of the L-shaped metal template 401 meet. Each of the two right-angled sides of the L-shaped metal template 401 is provided with a support platform 5 for supporting the wooden template 403. The support platform 5 is formed by extending horizontally outward from the edges of the two right-angled sides of the L-shaped metal template 401. The wooden template 403 is erected on the support platform 5. After the wooden template 403 is erected, its outer surface is flush with the outer surface of the L-shaped metal template 401. Adjustable support components 404 are provided at the bottom of the wooden template 403 to support the wooden template.

[0019] like Figure 3 As shown, the adjustable support assembly 402 includes a first screw 4021, a first adjusting nut 4022, and a first steel pipe 4023. The first screw 4021 is fixedly connected to the bottom of the midpoint of the connection between the two right-angled sides of the L-shaped metal template 401. The first steel pipe 4023 has a thread matching the first screw 4021, and the first screw 4021 is threadedly connected to the first steel pipe 4023. The first adjusting nut 4022 is threadedly connected to the first screw 4021. Rotating the first screw 4021 adjusts the height of the support assembly, and rotating the first adjusting nut 4022 fixes the height of the first screw 4021.

[0020] like Figure 3 As shown, the adjustable support assembly 404 includes a top support 4041 for supporting the wooden formwork, a second screw 4042, a second adjusting nut 4043, and a second steel pipe 4044; the top support 4041 is fixedly connected to the top of the second screw 4042; the second screw 4042 is threadedly connected to the second steel pipe 4044; the second adjusting nut 4043 is threadedly connected to the second screw 4042, rotating the second screw 4042 adjusts the height of the support assembly, and rotating the second adjusting nut 4043 fixes the height of the second screw 4042.

[0021] like Figures 1-4As shown, specifically, the first screw 4021 of the adjustable support component 402 is vertically welded to the bottom of the midpoint of the connection between the two right-angled sides of the L-shaped metal template 401; select a wooden template 403 of appropriate size, and place the wooden template 403 on the support platform 5 of the two right-angled sides of the L-shaped metal template 401 respectively, ensuring that the outer side of the wooden template 403 is in close contact with the inner wall of the edge of the support platform 5, and that the wooden template 403 is in contact with the anti-slip textured surface. The welded L-shaped metal template 401 is then pressed tightly against the bottom surface of the floor slab 3 and the side of the flue 2, and initially placed in the area to be sealed. The height of the support component is adjusted by rotating the first screw 4021, and the height of the first screw 4021 is fixed by rotating the first adjusting nut 4022, thus roughly adjusting the overall height of the L-shaped metal template 401 to initially fit against the surface of the flue 2 and the floor slab 3. Adjust the height of the support assembly by rotating the second screw 4042. This rotation drives the top support 4041 to rise until its upper surface is fully in contact with the bottom surface of the wooden formwork 403. Continue rotating the second screw 4042 to apply a tightening force to the wooden formwork 403, eliminating gaps between the wooden formwork 403 and the flue 2 and floor slab 3. Tighten the first and second adjusting nuts of the adjustable support assembly 402 and the adjustable support assembly 404 to ensure the first and second screws are securely fastened within the first and second steel pipes. Finally, pour concrete and remove the formwork.
