Description

Technical Field

[0001] This utility model relates to the field of prefabricated tube sealing equipment technology, specifically to an assembled prefabricated tube sealing template. Background Technology

[0002] In existing technologies, the structural design of precast pipe seal molds has some defects. For example, in our company's prior patent application No. 2024203400537, the first frame edge strip of the multi-segment precast template is fixedly connected to the mold body. This design is not flexible enough during demolding and easily leads to the precast pipe seal sticking to the mold, increasing the difficulty and time cost of demolding. That is, after the concrete has solidified, the adhesive force between the precast pipe seal and the first frame edge strip is large, and the fixed connection between the first frame edge strip and the mold body makes the demolding process require more manpower and time, making it difficult to achieve rapid demolding.

[0003] Specifically: When the pre-formed tube seal adheres to the mold body, forcibly demolding it may cause damage to the edges of the pre-formed tube seal, or even affect the integrity of its internal structure, thereby affecting its performance and reliability in practical applications. Summary of the Invention

[0004] This utility model proposes an assembled prefabricated pipe seal template, which solves the problem of inconvenient and rapid demolding of prefabricated pipe seals due to mold design defects in the existing technology.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A prefabricated pipe sealing template includes at least two base plates, which are hinged and flipped together by multiple hinges. Movable guide components are provided on both sides of the bottom of the base plates, and the movable guide components are provided with baffles that are flush with and abut against the sides of the base plates.

[0007] The movable guide assembly includes a support plate fixed to the bottom of the base plate. A top shaft with one end fixed to a retaining edge slides through the support plate. A guide tube is provided on the side of the support plate near the retaining edge and sleeved outside the top shaft. A spring is sleeved on the side of the top shaft away from the retaining edge. The two ends of the spring are fixed to the end of the top shaft and the side of the support plate, respectively. The end of the top shaft away from the retaining edge is pushed by an external force and slides along the guide tube, pushing the retaining edge away from the contact with the side of the base plate.

[0008] Furthermore, the retaining edge is a flat strip structure, which is either straight or multi-segment curved / wavy.

[0009] Furthermore, movable baffles are provided on opposite sides of the top of the two base plates, and the two ends of the baffles are flush with the side edges of the base plates and abut against the baffle edges.

[0010] Furthermore, the adjacent side of the two retaining ribs is inclined, or both sides of the retaining ribs are inclined.

[0011] Furthermore, the retaining rib has a through hole for positioning the embedded part of the pipe seal, and the through hole is parallel to the bottom plate.

[0012] Furthermore, a reinforcing rib is fixed to the bottom of the base plate.

[0013] Furthermore, the support plate has a sliding hole corresponding to the guide tube, and the top shaft passes through the sliding hole and slides along it.

[0014] The beneficial effects of the technical solution provided in this application are as follows:

[0015] 1. This prefabricated pipe seal template, by employing at least two base plates and hinged hinges for flipping, makes demolding more flexible and convenient, preventing the prefabricated pipe seal from sticking to the mold body, thus greatly reducing the difficulty and time cost of demolding. For example, after the concrete has solidified, operators can easily flip the base plates using the hinges to smoothly detach the prefabricated pipe seal from the mold.

[0016] 2. In this prefabricated pipe seal template, the top shaft in the movable guide assembly cooperates with the external push rod structure. Through linear drive, the top shaft moves straight along the guide tube, pushing the retaining edge away from the side of the base plate, thus separating the retaining edge from the prefabricated pipe seal. The spring design facilitates the top shaft's reset, ensuring a quick return to its initial state for the next use. For example, during demolding, the external push rod structure drives the top shaft, allowing the retaining edge to smoothly detach from the prefabricated pipe seal, avoiding damage to the prefabricated pipe seal edges caused by forced prying.

[0021] In the diagram: 10 base plate, 20 movable guide assembly, 21 support plate, 22 guide tube, 23 top shaft, 24 spring, 25 sliding hole; 30 edge retainer, 40 retaining rib, 50 reinforcing rib, 60 hinge. Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and 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 protection scope of this utility model.

[0023] Reference Figure 1-3 A prefabricated pipe seal template includes at least two base plates 10. The two base plates 10 are hinged and flipped together by multiple hinges 60. Movable guide components 20 are provided on both sides of the bottom of the base plates 10. The movable guide components 20 are provided with baffles 30 that are flush with and abut against the sides of the base plates 10. The hinges 60 can be bent into the required specifications according to the angle requirements of the pipe seal. In addition, the use of hinges 60 makes demolding easier. The formed pipe seal will not deform due to the angle change of the two base plates 10. When the two base plates 10 are flipped outward, the prefabricated pipe seal can be quickly separated from the whole.

[0024] The movable guide assembly 20 includes a support plate 21 fixed to the bottom of the base plate 10. A top shaft 23, one end of which is fixed to a retaining edge 30, slides through the support plate 21. A guide tube 22 is provided on the side of the support plate 21 near the retaining edge 30 and sleeved on the outside of the top shaft 23. A spring 24 is fitted on the side of the top shaft 23 away from the retaining edge 30. The two ends of the spring 24 are fixed to the end of the top shaft 23 and the side of the support plate 21, respectively. The end of the top shaft 23 away from the retaining edge 30 is pushed by an external force and slides along the guide tube 22, pushing the retaining edge 30 away from the contact with the side of the base plate 10. This assembly can ensure reliable contact between the retaining edge 30 and the side of the base plate 10, and can achieve smooth disengagement of the retaining edge by external force when needed. The support plate 21 is fixed to the bottom of the base plate 10, providing a stable sliding track for the top shaft 23. At the same time, the guide tube 22 ensures that the top shaft 23 slides in a straight line, and the spring 24 provides elastic force for the top shaft 23 to reset. The coordinated work of these components improves the efficiency of the demolding process and the quality of the pre-made tube seal.

[0025] After the prefabricated tube seal has been formed and cured, when demolding is required, an external force is used to push the top shaft 23 away from the end of the retaining edge 30, causing the top shaft 23 to slide along the guide tube 22. The sliding of the top shaft 23 drives the retaining edge 30 to move, thereby gradually disengaging the retaining edge 30 from the abutment state with the side of the base plate 10. When the retaining edge 30 is completely disengaged, the prefabricated tube seal can be removed from the base plate 10. After demolding is completed, the external force is removed, and the action of the spring 24 causes the top shaft 23 to return to its initial position, and the retaining edge 30 is reset, ready for the next demolding operation.

[0026] In some embodiments, the retaining edge 30 is a flat strip structure, which can be straight or multi-segment curved / wavy. This design aims to provide better stability during the assembly of multiple prefabricated pipe seals. The shape of the retaining edge allows it to fit tightly against the edge of the prefabricated pipe seal. Whether straight or multi-segment curved / wavy, it ensures tightness and consistency in the connection between the prefabricated pipe seals during assembly, thereby enhancing the stability and strength of the overall structure. After the prefabricated pipe seals are manufactured, the shape of the retaining edge 30 allows it to form a good fit with adjacent prefabricated pipe seals during assembly. For a straight retaining edge, it can be directly aligned with the ceiling or floor to form a stable connection. For a multi-segment curved / wavy retaining edge, its design can adapt to the curve changes of the prefabricated pipe seal edge, and the interlocking of the wavy sections enhances the stability of the joint.

[0027] In some embodiments, movable baffles 40 are provided on opposite sides of the top of the two base plates 10, with both ends of the baffles 40 flush with the sides of the base plates 10 and abutting against the retaining edges 30. The baffles 40 play a crucial role in the assembled precast pipe seal template. The retaining edges 30 are used to position the short sides of the precast pipe seal, while the baffles 40 are used to position the long sides. This design ensures the correct position of the precast pipe seal in the mold, thereby guaranteeing the dimensional accuracy and shape consistency of the precast pipe seal. Through the synergistic effect of the retaining edges and baffles, displacement or deformation of the precast pipe seal during the molding process can be effectively prevented.

[0028] By providing movable retaining ribs 40 on both sides of the pipe seal 10, the position of the retaining ribs 40 can be flexibly adjusted according to different size requirements, thereby meeting the specific requirements of different projects. In the prefabricated assembled pipe seal, the design of the movable retaining ribs 40 allows for relative displacement on the base plate 10 to adapt to different pipe seal size requirements. Adjustment can be achieved by using fasteners such as screws, with screw holes provided at different positions on the base plate 10 to meet screw adjustment needs. This design allows the pipe seal to better match the wall or other structures, improving installation accuracy and stability, while also facilitating later maintenance and adjustments.

[0029] In some embodiments, adjacent sides of the two retaining ribs 40 are sloped, or both sides of the retaining ribs 40 are sloped. During the molding stage of the precast pipe seal, the sloped design of the retaining ribs 40 matches the sloped sides of the precast pipe seal. When the precast pipe seal is removed from the mold and used in building construction, its sloped sides allow for easier filling with cement mortar. The sloped structure reduces the resistance that cement mortar may encounter during filling, making the plastering process smoother. In addition, the sloped surface can also promote the bonding between cement mortar and the precast pipe seal, improving the connection strength between the precast pipe seal and the wall or other structures.

[0030] In some embodiments, the retaining rib 40 has a through hole 41 for positioning the embedded part of the pipe seal, and the through hole 41 is parallel to the base plate 10. This design allows the embedded part to be accurately placed in a predetermined position during the casting of the precast pipe seal, thereby ensuring that the precast pipe seal can be firmly connected to the wall during subsequent installation. The embedded part can be a metal or non-metal embedded part. By connecting the expansion bolts on the wall to the embedded part, the connection stability between the precast pipe seal and the wall can be enhanced. During the fabrication of the precast pipe seal, the through hole 41 serves as a positioning mark to guide the embedded part to be correctly placed in the predetermined position. When concrete or other materials are poured into the mold and cured around the embedded part, the embedded part is fixed inside the precast pipe seal, and its position is aligned with the through hole 41. After curing, the precast pipe seal can be tightly connected to the wall through the expansion bolts on the embedded part during installation.

[0031] In some embodiments, a reinforcing rib 50 is fixed to the underside of the base plate 10. During the production of the precast pipe seal, the reinforcing rib 50 serves as a supporting structure for the base plate 10, bearing the pressure and weight generated during concrete curing. The reinforcing rib 50, through its fixed connection with the base plate 10, increases the rigidity of the base plate, enabling it to more effectively resist external forces and maintain its shape and positional stability. Thus, even under significant pressure during concrete pouring and curing, the base plate 10 remains stable, ensuring the quality and production efficiency of the precast pipe seal.

[0032] In some embodiments, the support plate 21 has a sliding hole 25 corresponding to the guide tube 22, through which the top shaft 23 passes and slides. The function of this design is to ensure that the top shaft 23 can slide smoothly and accurately on the support plate 21. The sliding hole 25 provides a dedicated channel for the top shaft 23, allowing it to move linearly along a predetermined path when subjected to external force, thereby effectively pushing the retaining edge 30 away from the side of the base plate 10.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
