Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a three-dimensional sealing device for flue hole. Background Technology

[0002] Traditional flue installation involves pre-drilling a hole in the floor slab that is larger than the flue's outer cross-sectional dimensions. Sealing the hole is done by using wires to suspend and support a formwork or other support structure above the opening during the main construction. Concrete is then poured to seal the gap between the flue and the opening. This construction process is cumbersome due to the limited operating space, the lack of tight contact between the formwork and the flue / ventilation duct, which easily leads to construction joints, and the tendency for grout leakage during concrete pouring. This results in poor sealing quality at the opening and common quality problems such as water seepage at the connection between the flue / ventilation duct and the floor slab.

[0003] In existing technologies, common sealing methods typically involve using wire to lift wooden formwork, fixing the formwork to the bottom of the floor slab, and securing the formwork around the flue. Concrete is then poured over the formwork to seal the gaps around the flue. However, this method is prone to deformation due to the self-weight of the poured concrete, hindering subsequent demolding and slowing down the overall demolding process. Therefore, inventing a three-dimensional sealing device for flue openings to address these issues has become a pressing problem for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a three-dimensional sealing device for flue holes, which aims to solve the problem that common sealing methods are prone to deformation due to the self-weight pressure generated after concrete pouring, making subsequent demolding inconvenient and thus reducing the overall demolding speed.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a three-dimensional sealing device for flue hole, including a pre-embedded frame and a first fixing block and a second fixing block set on the pre-embedded frame, wherein the side wall of the pre-embedded frame is provided with a pressure strip;

A shaft groove is provided on one side of the first fixing block. An installation groove is provided on the inner wall of the shaft groove. A rotating shaft is installed on the inner wall of the shaft groove. A torsion spring is sleeved on the outside of the rotating shaft. A positioning rod is installed at one end of the rotating shaft. A positioning frame is installed at one end of the positioning rod. An anti-slip pad is installed on the inner wall of the positioning frame.

[0008] The second fixing block is fixedly connected to the inner wall of the pre-embedded frame on the side away from the first fixing block, and a second positioning groove is provided at one end of the second fixing block.

[0009] Preferably, the two embedded frames are combined into an embedded box, one side of the pressure strip is fixedly connected to the outer wall of the embedded frame, and the first fixing block and the second fixing block provided on the inner wall of the two embedded frames are in opposite positions, and the first fixing block and the second fixing block fit together when the two embedded frames are combined.

[0010] Preferably, the outer wall of the rotating shaft and the inner wall of the shaft groove are rotatably connected, the side wall of the positioning rod is fixedly connected to one end of the rotating shaft, and the two side walls of the torsion spring are respectively fixedly connected to the mounting groove and one end of the positioning rod.

[0011] Preferably, a knob is fixedly connected to one side of the outer wall of the positioning rod, one end of the positioning rod is fixedly connected to one side of the outer wall of the positioning frame, and the side wall of the positioning frame is slidably connected to the first positioning groove and the second positioning groove.

[0012] Preferably, an adjustment groove is provided on one side of the first fixing block, a sliding groove is provided on the inner wall of the bottom end of the adjustment groove, and a pressing groove is provided on the inner wall of one side of the adjustment groove.

[0013] Preferably, an adjusting block is slidably connected to the inner wall of the adjusting groove, and an inclined surface is provided on one side of the adjusting block to slide against the side wall of the positioning rod. An adjusting rod is fixedly connected to one end of the adjusting block and slidably connected to the inner wall of the pressing groove, and a pressing block is fixedly connected to one end of the adjusting rod.

[0014] Preferably, the adjusting rod is fixedly connected to a slide rod that is slidably connected to the inner wall of the slide groove on the side wall near the lower part of the adjusting block.

[0015] The beneficial effects of this utility model are:

[0016] Two interlocking embedded frames are combined to form a whole embedded box. When a single embedded frame is demolded, the contact area with the concrete is reduced, and the friction is correspondingly reduced, rather than the overall large friction, thereby improving the demolding efficiency. At the same time, after being divided into two parts, the force is distributed, allowing for more even and controllable demolding, reducing the risk of damage to the embedded frame and concrete structure. In addition, the positioning components set between the embedded boxes can ensure the strength of the embedded frame after assembly, while facilitating subsequent disassembly and improving the overall disassembly and assembly efficiency.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example, refer to Figures 1-10 A three-dimensional sealing device for flue hole includes a pre-embedded frame 1 and a first fixing block 2 and a second fixing block 3 set on the pre-embedded frame 1. The side wall of the pre-embedded frame 1 is provided with a pressure strip 11.

[0031] The first fixing block 2 is fixedly connected to the inner wall of one side of the pre-embedded frame 1. A first positioning groove 21 is provided at one end of the first fixing block 2. A shaft groove 22 is provided on one side of the first fixing block 2. An installation groove 221 is provided on the inner wall of the shaft groove 22. A rotating shaft 4 is installed on the inner wall of the shaft groove 22. A torsion spring 44 is sleeved on the outside of the rotating shaft 4. A positioning rod 42 is installed at one end of the rotating shaft 4. A positioning frame 43 is installed at one end of the positioning rod 42. An anti-slip pad 45 is installed on the inner wall of the positioning frame 43.

[0032] The second fixing block 3 is fixedly connected to the inner wall of the pre-embedded frame 1 on the side away from the first fixing block 2, and a second positioning groove 31 is provided at one end of the second fixing block 3.

[0033] Furthermore, the two embedded frames 1 are combined into an embedded box. One side of the pressure strip 11 is fixedly connected to the outer wall of the embedded frame 1. The first fixing block 2 and the second fixing block 3 set on the inner wall of the two embedded frames 1 are in opposite positions. The first fixing block 2 and the second fixing block 3 fit together when the two embedded frames 1 are combined. The outer wall of the rotating shaft 4 is rotatably connected to the inner wall of the shaft groove 22. The side wall of the positioning rod 42 is fixedly connected to one end of the rotating shaft 4. The two side walls of the torsion spring 44 are fixedly connected to the mounting groove 221 and one end of the positioning rod 42, respectively. A knob 41 is fixedly connected to one side of the outer wall of the positioning rod 42. One end of the positioning rod 42 is fixedly connected to one side of the outer wall of the positioning frame 43. The side wall of the positioning frame 43 is slidably connected to the first positioning groove 21 and the second positioning groove 31.

[0034] It should be noted that: before use, the two embedded frames 1 are spliced ​​and assembled into a whole embedded box. The embedded frame 1 is made of aluminum alloy. The whole embedded box is flared from one end of the pressure strip 11 to the other end. When using, insert the end away from the pressure strip 11 into the flue hole until one side of the pressure strip 11 is flush with the wall and supported and fixed with the wall template. Then, pour concrete from the other end into the space between the embedded frame 1 and the hole to ensure accurate hole forming and smooth edges, forming a standardized flue hole for easy subsequent flue installation. During subsequent demolding, rotate the first fixing blocks 2 on the upper and lower sides. The knob 41 on one side causes the positioning rod 42 to drive the positioning frame 43 to rotate and disengage from the first positioning groove 21 and the second positioning groove 31. At the same time, the anti-slip pad 45 on the inner side of the positioning frame 43 disengages from the contact with the second fixing block 3, thereby engaging the limiting of the first fixing block 2 and the second fixing block 3. This allows the two embedded frames 1 to be disassembled and separated. When a single embedded frame 1 is demolded, the contact area with the concrete is reduced, and the friction is correspondingly reduced, rather than the overall large friction, thereby improving the demolding efficiency. At the same time, after being divided into two parts, the force is distributed, allowing for more even and controllable demolding, reducing the risk of damage to the embedded frame 1 and the concrete structure.

[0035] Furthermore, an adjustment groove 23 is provided on one side of the first fixing block 2, a sliding groove 231 is provided on the inner wall of the bottom end of the adjustment groove 23, a pressing groove 24 is provided on one side of the inner wall of the adjustment groove 23, an adjustment block 5 is slidably connected to the inner wall of the adjustment groove 23, an inclined surface is provided on one side of the adjustment block 5 that abuts and slides against the side wall of the positioning rod 42, an adjustment rod 51 is fixedly connected to one end of the adjustment block 5 and slidably connected to the inner wall of the pressing groove 24, a pressing block 511 is fixedly connected to one end of the adjustment rod 51, a sliding rod 52 is fixedly connected to the side wall of the adjustment rod 51 near the lower part of the adjustment block 5 and slidably connected to the inner wall of the sliding groove 231, a spring 53 is sleeved on the outer wall of the sliding rod 52, and the two side walls of the spring 53 are fixedly connected to the inner wall of the adjustment groove 23 and the outer wall of one side of the adjustment rod 51, respectively.

[0036] It should be noted that when separating the two pre-embedded frames 1, the positioning rod 42 rotates against the elastic force of the torsion spring 44. Simultaneously, the side wall of the positioning rod 42 moves against the inclined surface of the adjusting block 5, causing the adjusting block 5 to slide into the adjusting groove 23 by pressing the lower end of the spring 53. This continues until the positioning rod 42 passes through the adjusting block 5. The spring 53 then rebounds, causing the adjusting block 5 to move upwards until it returns to its initial position. At this point, releasing the knob 41 causes the positioning rod 42 to return to its original position under the action of the torsion spring 44, ensuring one side of the positioning rod 42 is firmly pressed against the other side, thus fixing the positioning frame 43. At this point, the positioning frame 43 is disengaged from the two positioning grooves, allowing for the separation of the two pre-embedded frames. The pre-embedded frame 1 can be quickly disassembled without the need for manual fixing of the positioning rod 42. During subsequent assembly of the pre-embedded frames 1, simply align the two frames, then press the pressing block 511 to cause the adjusting rod 51 to slide the adjusting block 5 into the adjusting groove 23 until the adjusting block 5 is fully inserted. At this point, the positioning rod 42 on one side of the adjusting block 5 rebounds under the action of the torsion spring 44, causing the positioning frame 43 at one end to quickly insert between the two positioning grooves, thus quickly completing the assembly of the two pre-embedded frames 1. The positioning components ensure the strength of the assembled pre-embedded frames 1 while facilitating subsequent disassembly, improving overall assembly and disassembly efficiency.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
