Description

A high-adhesion wall airtight L-shaped cement flue frame Technical Field

[0001] This utility model relates to the field of flue technology, and in particular to a high-adhesion wall airtight L-shaped cement flue frame. Background Technology

[0002] A flue is a channel or pipe system used to exhaust flue gas produced by the combustion of equipment such as stoves and boilers, or exhaust gases such as oil fumes produced during kitchen cooking.

[0003] Currently, in the construction of kitchen flues, traditional flues are limited by production, transportation and installation conditions, and are usually installed by splicing sections. This spliced ​​flue results in poor sealing at the joints between the flue and the wall, making gaps easy to appear at the joints, leading to problems such as smoke leakage and odor mixing during later use. At the same time, spliced ​​flues will cause excessive costs in terms of transportation and other aspects.

[0004] Therefore, we provide a high-adhesion, airtight L-shaped cement flue frame. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a high-adhesion wall-sealed L-shaped cement flue frame, achieving the effect of an integrated cement flue with good sealing effect at the joints.

[0006] In view of this, the present invention provides a high-adhesion wall airtight L-shaped cement flue frame, including a shear wall, wherein an L-shaped cement flue is connected to the inner surface of the shear wall, and the L-shaped cement flue adopts a cast-in-place integrated structure;

[0007] The L-shaped cement flue is composed of national standard hot-dip galvanized wire mesh and a transverse unloading system;

[0008] The L-shaped cement flue is formed by fixing and filling with a retractable aluminum inner mold and a right-angled outer template;

[0009] A pre-reserved check valve opening is provided on one side of the L-shaped cement flue.

[0010] Preferably, the inner and outer surfaces of the L-shaped cement flue are both made of high-precision molding, and the connection between the L-shaped cement flue and the shear wall and the upper and lower floors is designed to be seamless.

[0011] Preferably, the national standard hot-dip galvanized wire mesh is arranged in an L-shape, and several transverse unloading devices are connected to both ends of the national standard hot-dip galvanized wire mesh. The several transverse unloading devices located at the same end are vertically distributed, and the national standard hot-dip galvanized wire mesh is connected to both the upper and lower ends of the transverse unloading devices.

[0012] Preferably, the transverse unloading specification is 6# threaded steel bar, and the ends of several transverse unloading bars located at opposite ends of the national standard hot-dip galvanized mesh are connected to the inner side of the shear wall rebar, and the transverse unloading bars located at the upper and lower ends of the national standard hot-dip galvanized mesh are connected to the upper and lower floor rebar.

[0013] Preferably, the national standard hot-dip galvanized wire mesh is provided with a shrinkable aluminum inner mold and a right-angle outer template, both of which are L-shaped.

[0014] Preferably, the retractable aluminum inner mold and the right-angled outer template are simultaneously attached to the inner surface of the shear wall at both ends, the upper and lower ends of the retractable aluminum inner mold and the right-angled outer template are attached to the inner surfaces of the upper and lower floors, the inner side of the retractable aluminum inner mold is connected with an inner mold retraction rod, the right-angled outer template is fixed with fixing nails, and a filling port is provided through the outer surface of the right-angled outer template.

[0015] Preferably, the national standard hot-dip galvanized wire mesh, the retractable aluminum inner mold, and the right-angle outer template all have a reserved check valve opening through one side. A protective cap is inserted into the reserved check valve opening, and the outer surface of the protective cap is tightly fitted to the inner wall of the reserved check valve opening on the retractable aluminum inner mold and the right-angle outer template.

[0016] Compared with the prior art, this utility model provides a high-adhesion wall airtight L-shaped cement flue frame, which has the following beneficial effects:

[0017] This utility model adopts a cast-in-place, one-piece L-shaped cement flue. Compared with the segmented splicing design of traditional flues, it completely eliminates the traditional segmented splicing design, avoiding the problem of gaps caused by loose connections between the L-shaped cement flue and the wall. It structurally eliminates the risk of smoke leakage at the joints. Furthermore, the seamless connection of the L-shaped cement flue further improves the overall airtightness of the flue, greatly reducing the risk of smoke leakage caused by poor joints and the risk of cracking at the joints. This improves the overall stability of the L-shaped cement flue and reduces the transportation costs required for splicing the flue.

[0018] This invention, with its high-precision forming surface on the inner and outer surfaces of an L-shaped cement flue, effectively avoids secondary plastering, allowing it to be delivered directly as a finished product and reducing plastering costs.

[0019] This invention, under the lateral unloading action of multiple No. 6 threaded bars, enables the L-shaped cement flue to be tightly connected with the shear wall and the upper and lower floors, further improving the connection strength between the L-shaped cement flue and the wall, and preventing the L-shaped cement flue from shifting or loosening during use.

[0020] This invention, by pre-reserving a check valve opening, avoids damage to the L-shaped cement flue caused by hammering and drilling when opening the valve opening later, saves drilling costs, and facilitates maintenance and replacement.

[0029] Example: A high-adhesion wall airtight L-shaped cement flue frame, as shown in Figures 1-4, includes a shear wall 1, characterized in that an L-shaped cement flue 2 is connected to the inner surface of the shear wall 1, and the L-shaped cement flue 2 adopts a cast-in-place integrated structure.

[0030] The L-shaped cement flue 2 is composed of national standard hot-dip galvanized wire mesh 201 and transverse unloading 202;

[0031] The L-shaped cement flue 2 is formed by fixing and filling with a retractable aluminum inner mold 203 and a right-angle outer mold 204.

[0032] The inner and outer surfaces of the L-shaped cement flue 2 are both made with high-precision molding, and the connection between the L-shaped cement flue 2 and the shear wall 1 as well as the upper and lower floors is designed to be seamless.

[0033] The national standard hot-dip galvanized wire mesh 201 is L-shaped. Several horizontal unloading points 202 are connected to both ends of the national standard hot-dip galvanized wire mesh 201. Several horizontal unloading points 202 located at the same end are vertically distributed. Horizontal unloading points 202 are connected to both the upper and lower ends of the national standard hot-dip galvanized wire mesh 201.

[0034] The transverse unloading 202 is a 6# threaded steel bar, and several transverse unloading 202 located at opposite ends are connected to the inner side of the shear wall 1 with the end away from the national standard hot-dip galvanized mesh 201. The transverse unloading 202 located at the upper and lower ends of the national standard hot-dip galvanized mesh 201 are connected to the upper and lower floor rebars.

[0035] The national standard hot-dip galvanized wire mesh 201 is equipped with a retractable aluminum inner mold 203 and a right-angle outer template 204. Both the retractable aluminum inner mold 203 and the right-angle outer template 204 are L-shaped.

[0036] The retractable aluminum inner mold 203 and the right-angle outer mold 204 are simultaneously attached to the inner surface of the shear wall 1 at both ends. The upper and lower ends of the retractable aluminum inner mold 203 and the right-angle outer mold 204 are attached to the inner surfaces of the upper and lower floors. The inner side of the retractable aluminum inner mold 203 is connected to an inner mold retraction rod 205. The right-angle outer mold 204 is fixed with fixing nails. A filling port 206 is opened through the outer surface of the right-angle outer mold 204.

[0037] When installing the L-shaped cement flue 2, first install the shrinkable aluminum inner mold 203, then attach the outer surface of the shrinkable aluminum inner mold 203 to the inner surface of the shear wall 1 and the surfaces of the upper and lower floors. Next, install the national standard hot-dip galvanized wire mesh 201 according to the protective layer thickness of the L-shaped cement flue 2. Simultaneously, connect the transverse unloading 202 to the shear wall 1 and the upper and lower floors with reinforcing bars. After the national standard hot-dip galvanized wire mesh 201 and the transverse unloading 202 are installed, install the right-angle outer formwork 204 according to the protective layer thickness, and then... The retractable aluminum inner mold 203 and the right-angle outer mold 204 are secured by the inner mold retraction rod 205 and fixing nails, respectively. Finally, mortar is conveyed from the filling port 206 on the right-angle outer mold 204 to the space between the retractable aluminum inner mold 203 and the right-angle outer mold 204. After the mortar has solidified, the inner mold retraction rod 205 is rotated and the fixing nails are removed to complete the demolding of the retractable aluminum inner mold 203 and the right-angle outer mold 204. The L-shaped cement chimney installation is now complete, using a cast-in-place integrated molding method. The L-shaped cement flue 2, compared to the segmented splicing design of traditional flues, completely eliminates the traditional segmented splicing design, avoiding the problem of gaps caused by loose connections between the L-shaped cement flue 2 and the wall. Structurally, it eliminates the risk of smoke leakage at the joints. Furthermore, the seamless connection of the L-shaped cement flue 2 further improves the overall airtightness of the flue, greatly reducing the risk of smoke leakage caused by poor joint connections and also reducing the risk of cracking at the joints. This improves the overall stability of the L-shaped cement flue 2, further reducing the use of splicing sleeves and lowering costs. At the same time, it reduces the transportation costs required for spliced ​​flues. The high-precision forming surface of the inner and outer surfaces of the L-shaped cement flue 2 effectively avoids secondary plastering, allowing it to be delivered directly as a finished product, reducing plastering costs. Under the action of the lateral unloading 202 of multiple 6# threaded ribs, the L-shaped cement flue 2 can be tightly connected to the shear wall 1 and the upper and lower floors, further improving the connection strength between the L-shaped cement flue 2 and the wall 1, preventing displacement or loosening of the L-shaped cement flue 2 during use.

[0038] As shown in Figures 1-4, a reserved check valve opening 4 is provided through one side of the national standard hot-dip galvanized wire mesh 201, the retractable aluminum inner mold 203, and the right-angle outer template 204. A protective cap 3 is inserted into the reserved check valve opening 4, and the outer surface of the protective cap 3 is tightly fitted to the inner wall of the reserved check valve opening 4 on the retractable aluminum inner mold 203 and the right-angle outer template 204.

[0039] Before pouring the L-shaped cement flue 2, insert the protective cap 3 into the reserved check valve opening 4. Under the function of the protective cap 3, firstly, the integrity of the reserved check valve opening 4 can be guaranteed, avoiding the problem of ash burying the opening. Secondly, the protective cap 3 can prevent debris from entering the interior of the L-shaped cement flue 2 through the reserved check valve opening 4 after the L-shaped cement flue 2 is made, ensuring that the interior of the L-shaped cement flue 2 is clean and tidy. Under the reserved check valve opening 4, damage to the L-shaped cement flue 2 caused by hammering and drilling when opening the valve opening can be avoided, saving drilling costs and facilitating maintenance and replacement.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
