Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a device and construction method for intercepting concrete between a hanging plate and a column. Background Technology

[0002] In building construction, the connection between the underlayment and the column is a crucial node, and its construction quality directly affects the structural safety and service life of the entire building.

[0003] In traditional construction methods, the complex shape of the connection between the lower hanging plate and the column makes interception difficult and inconvenient during the interception process. This is especially true when the size of the lower hanging plate is increased, making reinforcement with the interception net even more difficult. This can easily lead to grout leakage and runoff during concrete pouring, resulting in insufficient concrete density at the joint and affecting the structural strength. Therefore, a special device is needed to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a device and construction method for intercepting concrete between a lower hanging plate and a column, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a concrete interception device for a lower hanging plate and column, comprising multiple interception mesh frames, which are assembled end to end and installed in a lower hanging plate. The lower hanging plate is fixed to one side of the structural column. The interception mesh frame includes two connecting frames and a wire mesh fixed between the two connecting frames. A connecting pipe is inserted and fixed at one end of the connecting frame, and an insertion port is opened at the other end of the connecting frame. Inserts are inserted into the top and bottom surfaces of the connecting pipe. One end of the insert is connected to an installation component via a spring, and the installation component is fixed to one end of the connecting pipe. After the two sets of connecting frames are assembled end to end, the connecting pipe at the end of one set of connecting frames is inserted into the end of the other set of connecting frames, and the plug is inserted into the corresponding socket.

[0006] Preferably, the length of the wire mesh is equal to the length of the connecting frame, and half of the connecting pipe is inserted into the connecting frame.

[0007] Preferably, the mounting assembly includes a sealing plate and a partition plate fixed to the surface of the sealing plate. The partition plate and the sealing plate are perpendicular. The top and bottom plates of the connecting pipe are provided with through holes. The insert block is inserted into the through holes, and the spring is fixed between the insert block and the partition plate.

[0008] Preferably, the end of the insert protruding from the through hole is provided with an inclined surface, which faces away from the connecting frame. When the two sets of connecting frames are connected end to end and pushed forward, the insert at the end of one set of connecting frames is squeezed into the connecting tube along the inclined surface. At this time, the spring is compressed and undergoes elastic deformation. As the connecting tube continues to advance, when the insert and the socket correspond, the spring rebounds and pushes the insert into the through hole.

[0009] Preferably, the top and bottom surfaces of the connecting frame are fixed with rubber sealing plates, which seal the insertion ports.

[0010] Preferably, two rubber support plates are fixed between the insert block and the partition plate, and the two rubber support plates are symmetrically distributed about the insert block.

[0011] A method for constructing a concrete interception system between a lower slab and a column, the method comprising the following steps: Multiple sets of interception mesh frames are pre-welded, and after being spliced ​​together end to end, they are fixed in the lower hanging plate to form an interception device in the lower hanging plate, which effectively intercepts the concrete between the lower hanging plate and the column.

[0012] Compared with the prior art, the beneficial effects of the present invention are: The present invention proposes a concrete interception device and construction method for the lower hanging plate and column. By installing an interception mesh frame in the lower hanging plate, this device can effectively prevent grout leakage and runoff at the connection between the structural column and the lower hanging plate during concrete pouring. The interception mesh frame plays a role in interception and sealing, ensuring that concrete does not leak from the connection during the pouring process, thus guaranteeing the quality of concrete pouring, reducing concrete waste, and lowering construction costs.

[0013] Ensuring concrete density and structural strength: Ensuring the density of the concrete at the joints allows it to fully fill the connection between the structural columns and the lower slab, improving the structural strength of the joint. This helps enhance the stability and safety of the entire building structure, extends its service life, and reduces repair and maintenance costs caused by structural problems later on.

[0014] Easy assembly and disassembly: The connecting frame of the interceptor mesh structure is ingeniously designed. Through the cooperation of components such as connecting pipes, inserts, springs, and rubber support plates, the two sets of connecting frames can be easily assembled and disassembled. During assembly, simply insert the connecting pipe at the end of one set of connecting frames into the end slot of the other set. During the pushing process, the insert will automatically be pushed in and reset to achieve a locking and fixing position. During disassembly, press the rubber sealing plate to push the insert to detach it from the insertion slot, and then pull out the connecting frame to complete the disassembly. This design greatly improves construction efficiency, facilitates the installation and disassembly of the device, and allows for repeated use in different construction scenarios.

[0015] Good structural stability: Two rubber support plates, symmetrically distributed about the insert block and fixed between the insert block and the partition plate, work together with the spring to provide a more stable rebound thrust when the insert block is inserted into the socket, which enhances the anti-disengagement and locking effect after the two sets of connecting frames are spliced, making the entire interception net frame structure more stable and reliable, and able to better withstand the pressure and impact of concrete pouring.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1, please refer to Figures 1 to 8 This invention provides a technical solution: a concrete interception device for a lower hanging plate and column, comprising multiple interception mesh frames 3. The multiple interception mesh frames 3 are assembled end to end and installed in a lower hanging plate 2. The lower hanging plate 2 is fixed to one side of a structural column 1. The interception mesh frame 3 includes two connecting frames 302 and a wire mesh 301 fixed between the two connecting frames 302. A connecting pipe 4 is inserted and fixed at one end of the connecting frame 302, and an insertion port 303 is opened at the other end of the connecting frame 302. Insert blocks 404 are inserted into the top and bottom surfaces of the connecting pipe 4. One end of the insertion block 404 is connected to an installation component through a spring 405. The installation component is fixed to one end of the connecting pipe 4. After the two sets of connecting frames 302 are assembled end to end, the connecting pipe 4 at the end of one set of connecting frames 302 is inserted into the end of the other set of connecting frames 302, and the insertion block 404 is inserted into the corresponding insertion port 303.

[0020] To prevent grout leakage and runoff at the connection between structural column 1 and lower hanging plate 2, an intercepting mesh frame 3 was installed in the lower hanging plate 2, which effectively solved this problem and ensured the sealing of the concrete during pouring; it also ensured the density of the concrete and the structural strength at the joint.

[0021] To ensure the insertion of the insert 404 into the connecting pipe 4 and to satisfy the connection limit after the two sets of connecting frames 302 are assembled end to end, the following is proposed: The mounting assembly includes a sealing plate 401 and a partition plate 402 fixed to the surface of the sealing plate 401. The partition plate 402 is perpendicular to the sealing plate 401. Both the top and bottom plates of the connecting pipe 4 have through holes 403. Insert blocks 404 are inserted into the through holes 403, and springs 405 are fixed between the insert blocks 404 and the partition plate 402. One end of the insert block 404 extending out of the through hole 403 has a bevel, facing away from the connecting frame 302. When the two sets of connecting frames 302 are connected end-to-end and pushed forward, the insert block 404 at the end of one set of connecting frames 302... 4 is squeezed into the connecting tube 4 along the inclined surface. At this time, the spring 405 is compressed and undergoes elastic deformation. As the connecting tube 4 continues to advance, when the insert 404 and the socket 303 correspond, the spring 405 rebounds and pushes the insert 404 into the through hole 403. The top and bottom surfaces of the connecting frame 302 are both fixed with rubber sealing plates 304, which cover the socket 303. Two rubber support plates 406 are fixed between the insert 404 and the partition 402. The two rubber support plates 406 are symmetrically distributed about the insert 404.

[0022] Select the required number of interception net frames 3 according to the needs, align the ends of multiple interception net frames 3 and splice and fix them together. The specific operation is as follows: insert the connecting tube 4 at the end of one set of connecting frames 302 into the end slot of another set of connecting frames 302. During the pushing process of one set of connecting frames 302, the other set of connecting frames 302 squeezes the insert block 404 at the end of one set of connecting frames 302 into the through hole 403. At this time, the spring 405 and the rubber support plate 406 are both squeezed by the insert block 404 and undergo elastic deformation. When the part of the connecting tube 4 extending out of the connecting frame 302 is completely inserted into the other set of connecting frames 302... Then, the insert 404 corresponds to the socket 303. The spring 405 and the rubber support plate 406 rebound and push the insert 404 back to its original position. After being reset, the insert 404 is inserted into the corresponding through hole 403. In this way, the insert 404 forms an anti-disengagement locking position between the two sets of connecting frames 302. When it is necessary to separate the two sets of connecting frames 302, press the rubber sealing plate 304 with your finger and push the insert 404 into the corresponding through hole 403 through the rubber sealing plate 304. That is, after the insert 404 is separated from the socket 303, pull the connecting frame 302 to remove the connecting tube 4 from the other set of connecting frames 302.

[0023] The usage method of the lower hanging plate and column concrete interception device is as follows: Interception frame 3 splicing: Select the required number of interception frames 3 according to actual needs.

[0024] End-to-end alignment and splicing: Align the ends of multiple intercepting net frames 3 in preparation for splicing and fixing. Specifically, insert the connecting pipe 4 at the end of one set of connecting frames 302 into the end slot of another set of connecting frames 302.

[0025] Pushing and splicing: Pushing one set of connecting frames 302, during the pushing process, another set of connecting frames 302 pushes the insert 404 at the end of the first set of connecting frames 302 into the through hole 403 of the connecting tube 4 along its inclined surface. At this time, the spring 405 and the rubber support plate 406 are both squeezed by the insert 404 and undergo elastic deformation.

[0026] Complete splicing: When the part of the connecting tube 4 extending out of the connecting frame 302 is fully inserted into another set of connecting frames 302, the insert block 404 and the socket 303 correspond. The spring 405 and the rubber support plate 406 rebound and push the insert block 404 back to its original position. After the insertion block 404 is reset, it is inserted into the corresponding socket 303. In this way, the insert block 404 forms an anti-disengagement locking position between the two sets of connecting frames 302, thus completing the splicing and fixing of multiple interception net frames 3.

[0027] Install the intercepting mesh frame 3: Install the assembled intercepting mesh frame 3 as a whole in the lower hanging plate 2, which is fixed to one side of the structural column 1. By installing the intercepting mesh frame 3 in the lower hanging plate 2, leakage and runoff of grout at the connection between the structural column 1 and the lower hanging plate 2 can be avoided, ensuring the sealing of the concrete during pouring and guaranteeing the density and structural strength of the concrete at the joint.

[0028] Disassembling the interception frame 3: When it is necessary to disassemble the two sets of connecting frames 302, press the rubber sealing plate 304 with your finger, and push the insert 404 through the rubber sealing plate 304, so that the insert 404 retracts into the corresponding through hole 403, that is, the insert 404 disengages from the socket 303. Then, pull the connecting frame 302 to remove the connecting pipe 4 from the other set of connecting frames 302, completing the disassembly of the two sets of connecting frames 302.

[0029] Example 2, based on Example 1, proposes a construction method for concrete interception between the lower hanging plate and the column, the method including the following steps: Multiple sets of interception net frames 3 are pre-welded, and after the multiple interception net frames 3 are spliced ​​end to end, they are fixed in the lower hanging plate 2 to form an interception device in the lower hanging plate 2, which effectively intercepts the concrete between the lower hanging plate and the column.
