Therefore, a large number of reserved holes for pipelines to pass through the floor slabs need to be set in high-rise buildings, and the workload of secondary plugging of these reserved holes is relatively large. And areas such as caissons and bathrooms have relatively high requirements for the tightness of secondary plugging.

However, in actual applications, this type of connection method using bolts will result in cumbersome operations and increased construction time. Summary of the Invention

The fitting units are provided with through holes, the docking plate is provided with docking holes, and the through holes are aligned with the docking holes and are inserted and connected with a pin unit. In this application, by respectively arranging fitting units and a docking plate on the fitting formwork and the docking formwork, and snap-connecting the docking plate to the fitting grooves, the preliminary connection between the docking formwork and the fitting formwork is completed. Further, fitting grooves are arranged on the fitting units, and docking holes are arranged on the docking plate, so that the pin unit can pass through the through holes and the docking holes to connect the two, and further, the fitting formwork and the docking formwork can be limited and constrained. In this application, due to the use of the connection method of inserting the pin unit into the through holes and the docking holes, the use of bolts for connection is avoided, thereby improving the installation and disassembly efficiency. Further, due to the use of the pin unit, the material of the pin unit is the same as that of the fitting formwork and the docking formwork, avoiding the use of metal materials, reducing the material processing cost, and at the same time reducing the overall weight, which is convenient for transportation and installation.

[0007] Preferably, the pin unit includes a pin body connecting the through hole and the docking hole. A disassembly head is arranged at the end of the pin body, and a disassembly hole is arranged on the disassembly head.

[0011] Preferably, a plurality of prying grooves are provided on the bolt body along the disassembly direction. Since a plurality of prying grooves are provided, the weight can be further reduced. At the same time, since the prying grooves adopt a groove-shaped structure, the structural strength of the bolt unit can be ensured, and holes are avoided from being generated at this position, thereby forming compressive deformation.

[0029] Embodiment 1:

[0030] As Figure 1 , 3 shown, a plug-in backfill template includes a fitting template 1 and a docking template 2. The fitting template 1 is provided with fitting units 11, and the fitting units 11 are provided with fitting grooves 12. The docking template 2 includes a docking plate 21, and the docking plate 21 is snap-connected to the fitting groove 12. The fitting unit 11 is provided with perforations 13, and the docking plate 21 is provided with docking holes 22. The perforations 13 and the docking holes 22 are aligned and inserted with a plug unit 3. In this application, by respectively providing fitting units 11 and docking plates 21 on the fitting template 1 and the docking template 2, and snap-connecting the docking plate 21 to the fitting groove 12, the preliminary connection of the docking template 2 and the fitting template 1 is completed. Further, a fitting groove 12 is provided on the fitting unit 11, and a docking hole 22 is provided on the docking plate 21, so that the plug unit 3 can pass through the perforation 13 and the docking hole 22 to connect the two, and thus the fitting template 1 and the docking template 2 can be limited and constrained. In this application, since the connection method of inserting the plug unit 3 into the perforation 13 and the docking hole 22 is adopted, the use of bolts for connection is avoided, thereby improving the installation and disassembly efficiency. Further, since the plug unit 3 is adopted, the material of the plug unit 3 is the same as that of the fitting template 1 and the docking template 2, avoiding the use of metal materials, reducing the material processing cost, and at the same time reducing the overall weight, which is convenient for transportation and installation.

[0031] As shown Figure 4 in the figure, the bolt unit 3 includes a bolt body 31 connecting the through hole 13 and the docking hole 22. A disassembly head 32 is provided at the end of the bolt body 31, and a disassembly hole 321 is provided on the disassembly head 32. The disassembly head 32 is provided on the bolt body 31, and the disassembly hole 321 is provided on the disassembly head 32. Therefore, during the disassembly process, a long rod tool can be used to hook the disassembly hole 321, and then the bolt unit 3 can be removed from the through hole 13 and the docking hole 22 at a distance. Further, holes can also be provided on the fitting template 1 and the docking template 2, so that the fitting template 1 and the docking template 2 can also be removed at a distance.

[0032] As shown Figure 4 in the figure, the bolt unit 3 includes a connecting head 33, and a guiding inclined surface 331 is provided on the connecting head 33. The guiding inclined surface 331 is provided on the connecting head 33, so as to improve the smoothness of the bolt unit 3 penetrating into the through hole 13 and the docking hole 22.

[0033] As shown Figure 4 in the figure, the bolt unit 3 has a conical-like structure. The bolt unit 3 is set to have a conical-like structure, so that the bolt unit 3 can increase the connection tightness with the through hole 13 and the docking hole 22 as it moves continuously, and it is convenient for remote disassembly. As long as force is applied, the bolt unit 3 can be taken out without additional disassembly skills, and the operation requirements are low.

[0034] As shown Figure 4 in the figure, the bolt unit 3 includes a bolt body 31 connecting the through hole 13 and the docking hole 22, and a pry slot 311 is provided on the bolt body 31. A plurality of pry slots 311 are provided on the bolt body 31 along the disassembly direction. A weight-reducing slot 312 is provided on the bolt unit 3.

[0035] The pry slot 311 is provided on the bolt body 31. Through the pry slot 311, tools such as a screwdriver can be directly inserted into the pry slot 311, and the bolt body 31 can be directly pried up through the fitting unit 11, so as to facilitate the operation of the bolt unit 3 by the staff during close-range work, avoiding the problem that it is not easy to exert force when connecting the disassembly hole 321 with a hook during close-range work. Since a plurality of pry slots 311 are provided, the weight can be further reduced. At the same time, since the pry slot 311 adopts a groove-shaped structure, the structural strength of the bolt unit 3 can be ensured, and holes are avoided at this place, thereby forming compressive deformation. The weight can be reduced by the weight-reducing slot.

[0036] As shown Figure 2As shown, both the perforation 13 and the docking hole 22 are kidney-shaped holes, and the pin unit 3 is a flat plate-like structure. By setting the perforation 13 and the docking hole 22 as kidney-shaped holes and setting the pin unit 3 as a flat plate-like structure whose shape adapts to the kidney-shaped holes, the lateral compressive resistance can be improved. At the same time, the flat plate-like structure is convenient for machining on the flat surface and can limit and constrain the circumferential direction of the pin unit 3 itself, thereby ensuring the accuracy of the relative position and facilitating subsequent long-distance disassembly operations.

[0037] As Figure 3 shown, the fitting groove 12 includes a guiding and expanding opening 121, and the docking plate 21 is provided with a narrowing end 211. By providing the guiding and expanding opening 121 and the narrowing end 211, the smoothness of the connection can be ensured, and it has a certain guiding effect during the connection process.

[0038] As Figure 2 shown, the fitting template 1 is provided with fitting reinforcing ribs 14, and the fitting reinforcing ribs 14 are connected to the fitting unit 11; and / or the docking template 2 is provided with docking reinforcing ribs 23, and the docking reinforcing ribs 23 are connected to the docking plate 21. By providing the fitting reinforcing ribs 14 on the fitting template 1, the docking reinforcing ribs 23 on the docking template 2, and connecting the fitting reinforcing ribs 14 and the docking reinforcing ribs 23 to the fitting unit 11 and the docking plate 21 respectively, not only can the structural strength of the fitting template 1 and the docking template 2 itself be improved, but also a supporting effect can be provided for the fitting unit 11 and the docking plate 21, avoiding deformation of the fitting unit 11 and the docking plate 21 during the installation and disassembly of the pin unit 3.

[0039] In this embodiment, the assembly and working process of the plug-in backfill formwork are as follows: In this embodiment, the designer has a fitting formwork 1 and a docking formwork 2, and the fitting formwork 1 and the docking formwork 2 clamp the pipeline between them. Further, a fitting unit 11 is provided on the fitting formwork 1. The fitting unit 11 includes two plate-like structures, and a fitting groove 12 is formed between the two plate-like structures. A docking plate 21 is provided on the docking formwork 2, and the docking plate 21 can be snap-connected into the fitting groove 12. In this embodiment, fitting units 11 are provided on both sides of the fitting formwork 1, and docking plates 21 are also provided on both sides of the docking formwork 2. Therefore, during the connection process, when the fitting formwork 1 is connected to the docking formwork 2, the two docking plates 21 are correspondingly connected to the two fitting grooves 12. A perforation 13 is provided on the fitting unit 11, and the perforations 13 are respectively provided on the upper and lower sides of the fitting groove 12. A docking hole 22 is also provided on the docking plate 21. When the docking plate 21 is connected to the fitting groove 12, the docking hole 22 is aligned with the perforation 13. Therefore, after the docking hole 22 and the perforation 13 are aligned, a pin unit 3 can be connected. In this embodiment, the pin unit 3 is a conical-like structure, showing a structure that is wider at the top and narrower at the bottom in the figure. When the pin unit 3 is inserted into the perforation 13 and the docking hole 22, the fitting formwork 1 and the docking formwork 2 are limited and constrained, and thus it can be ensured that the fitting formwork 1 and the docking formwork 2 clamp the pipeline in the middle area and fix it.

[0040] Further, in this embodiment, the overall structure of the plug unit 3 is a flat plate-like structure. The extending direction of the flat structure of the plug unit 3 is the same as the separating direction of the fitting module and the docking module. At the same time, both the through hole 13 and the docking hole 22 are set as waist-shaped holes to adapt to the flat plate-like structure of the plug unit 3. By setting it as a flat structure, the plug unit 3 can better resist the tendency of the fitting template 1 and the docking template 2 to separate, improving the stability of the limit. At the same time, the shape of the plug unit 3 along the plugging direction is a conical structure, showing a structure that is wider at the top and narrower at the bottom in the figure. Thus, as the plug unit 3 gradually moves downward, the connection limit effect on the fitting groove 12 and the docking plate 21 is stronger. At the lower end of the plug unit 3, that is, at the end with a smaller cross-sectional size of the plug unit 3, a guiding inclined surface 331 is provided. In this embodiment, the guiding inclined surface 331 is a chamfer structure arranged in a circle at the end of the plug unit 3, facilitating the insertion of the plug unit 3 into the through hole 13 and the docking hole 22 during the installation process. At the end of the plug unit 3 away from the guiding inclined surface 331, a disassembly head 32 is provided. The size of the disassembly head 32 is the largest area of the entire plug unit 3. A disassembly hole 321 is provided on the disassembly head 32. During the disassembly process, the plug unit 3 can be hooked out by passing a hook through the disassembly hole 321, facilitating the staff to exert force during the disassembly process. Further, in this embodiment, the plug unit 3 includes a plug body 31 connecting the through hole 13 and the docking hole 22. A plurality of prying grooves 311 are provided on the plug body 31. The prying grooves 311 are arranged from top to bottom, and the side of the prying groove 311 close to the disassembly head 32 is a plane. Therefore, during the disassembly process, a screwdriver can be inserted into the prying groove 311 and the plug unit 3 can be pried upward with the fitting unit 11 as a fulcrum. When the staff approaches the device of the present application and it is not easy to exert force through the disassembly hole 321, it is convenient for disassembly. At the same time, when the connection between the plug unit 3 and the through hole 13 and the docking hole 22 is too tight, the prying groove 311 can be used to facilitate loosening, ensuring the disassembly efficiency. During the production process, setting the prying grooves 311 can reduce the overall weight and save material costs. Further, a weight-reducing groove 312 is also provided on the plug unit 3, and the overall weight can be further reduced through the weight-reducing groove 312.

[0041] Further, in this embodiment, semi-circular grooves for docking with the pipeline are provided on the fitting template 1 and the docking template 2. The opening size of the semi-circular grooves is slightly smaller than the diameter of the pipeline. Therefore, when the fitting template 1 and the docking template 2 are placed on the pipeline, the ports of the fitting template 1 and the docking template 2 can clamp the pipeline, thereby realizing the pre-connection of the fitting template 1 and the docking template 2 on the pipeline, facilitating the subsequent connection of the plug unit 3 to the fitting template 1 and the docking template 2.

[0042] In the actual installation and disassembly process, first pre-connect the fitting template 1 and the docking template 2 to the pipeline. The pipeline is clamped by the port of the fitting template 1 that is slightly smaller than the docking template 2. When placing the fitting template 1 and the docking template 2, it is necessary to align the fitting groove 12 on the fitting template 1 with the docking plate 21 on the docking template 2. After the fitting template 1 and the docking template 2 are pre-connected to the pipeline, the docking plate 21 is engaged with the fitting groove 12. The docking plate 21 is provided with a narrowed end 211, and the fitting groove 12 is provided with a guiding and expanding opening 121. During the docking process, the smoothness of the docking can be ensured through the guiding docking of the narrowed end and the guiding and expanding opening 121. After the two are docked, confirm that the perforation 13 and the docking hole 22 are aligned, and then insert the pin unit 3 into the perforation 13 and the docking hole 22 for pre-connection. The fitting groove 12 and the docking plate 21 at the other end are fixed by hand. After the pre-connection at this end is completed, place the pin unit 3 in the perforation 13 and the docking hole 22 on the other side for pre-connection, and then use a hammering tool such as a hammer to tighten the pin units 3 on both sides to maintain the tightness of the connection.

[0043] During the disassembly process, either close-range operation or long-range operation can be selected. During close-range operation, the staff can pry open the prying groove 311 on the pin unit 3 with a screwdriver, then remove the pin unit 3 from the perforation 13 and the docking hole 22, and separate the fitting template 1 and the docking template 2. During long-range operation, the staff can pass a long rod hook through the disassembly hole 321 on the disassembly head 32 and forcefully remove the pin unit 3 from the perforation 13 and the docking hole 22, and then use the hook to separate the fitting template 1 and the docking template 2 from the pipeline. There are holes on the fitting template 1 and the docking template 2 that can connect the hook, which facilitates disassembly. The device in this embodiment can reduce the construction steps by setting the pin unit 3 to be inserted into the fitting template 1 and the docking template 2, thereby accelerating the construction efficiency, reducing the production process of parts, and lowering the production and processing costs; it can improve the flexibility of disassembly and installation, and two methods of close-range disassembly and long-range disassembly can be selected; it can ensure the smoothness of the installation and disassembly process and improve the work efficiency.
