Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mold closing devices, and particularly relates to a multi-number sleeve mold closing assembly. Background Art
[0002] In modern construction projects, sleeves are usually used for pre-burying pipelines or reserving holes for subsequent installation of pipelines or other facilities. The correct installation of sleeves is crucial for ensuring the functionality and safety of the entire building. However, when multiple sleeves are arranged at the same position, if the gaps between them are not properly handled, a series of problems will occur during concrete pouring.
[0003] Currently, for the mold closing work in this situation, the common practice is to fill with foam plastic boards and then close the mold, or use wire meshes to close the mold. Although these two methods can meet the construction requirements to a certain extent, they also have significant defects. First, due to the physical property limitations of foam plastic boards and wire meshes, it is difficult to completely avoid the phenomena of mold explosion (i.e., the template breaks due to excessive internal pressure) or slurry leakage (concrete slurry overflows from the template gap) during concrete pouring. These problems will not only lead to waste of concrete materials, resulting in the actual amount of concrete used exceeding the expected value, namely the so-called "over-square", but also seriously affect the quality and progress of the project. Content of the Utility Model
[0004] Aiming at the above problems in the prior art, the utility model provides a multi-number sleeve mold closing assembly, which solves the problems of mold explosion or slurry leakage existing in the prior art when using foam plastic boards or wire meshes to close the molds of multiple sleeves.
[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0006] Provide a multi-number sleeve mold closing assembly, including at least two opposing and parallelly arranged mold closing plates. Each mold closing plate is evenly provided with a plurality of first through holes and second through holes for sleeves to pass through; the middle part of each mold closing plate includes a plurality of first modules and a plurality of second modules that are detachably spliced with each other. The four corners of each mold closing plate are four third modules, and the four third modules are respectively detachably connected to the first modules; each first through hole is formed by splicing two first modules, two second modules and one third module. The four second through holes are respectively located at the four corners of the mold closing plate, and each second through hole is formed by splicing two first modules and two second modules.
[0007] The working principle of this solution is as follows: Before construction, clean the debris on the surfaces of multiple sleeves; during construction, splice multiple first modules, second modules, and third modules on the multiple sleeves to form a formwork. Since the first through-hole and the second through-hole for the sleeve to pass through are both spliced, they can undergo a certain deformation due to the mutual fixing force, resulting in a more seamless fit with the sleeve, improving the density. Compared with using foam plastic boards or wire meshes for formwork sealing, the formwork installation is simpler, and the corresponding modules fit better with the sleeves, avoiding slurry leakage. Moreover, the strength of the formwork is higher than that of foam plastic boards, reducing the risk of formwork explosion. Additionally, due to the modular design, it can be reused repeatedly.
[0008] Furthermore, each second module is a square plate structure, and first rounded openings are provided at the four corners of each second module; the top and bottom of each second module are respectively detachably connected to two first modules. Each first module is an isosceles trapezoidal plate structure, and second rounded openings are respectively provided at both ends of the first module; each first through-hole is spliced by two adjacent first rounded openings and two adjacent second rounded openings. The second module and the first module are a square plate structure and an isosceles trapezoidal plate structure respectively, with simple structures, facilitating the splicing by workers and reducing the construction difficulty.
[0009] Furthermore, the four third modules are all isosceles right-angled triangle plates, and the hypotenuse of each third module is a third rounded opening; each second through-hole is spliced by one first rounded opening, two second rounded openings, and one third rounded opening. The setting of the third module as an isosceles right-angled triangle plate is suitable for the four-corner areas of the formwork.
[0010] Furthermore, the central angles of the first rounded opening, the second rounded opening, and the third rounded opening are all 90°.
[0011] Furthermore, the height of the first module is the same as the radius of the second rounded opening.
[0012] Furthermore, the length of the short side of the first module is equal to the length of the straight side of the second module, and the length of the long side of the first module is equal to the sum of the length of the straight side of the second module and the diameter of the first rounded opening.
[0013] Furthermore, the length of the straight side of the third module is equal to the radius of the third rounded opening.
[0014] Furthermore, multiple threaded sleeves for cooperating with bolts are provided at the splicing joints on the surfaces of each first module, each second module, and each third module. Each threaded sleeve is used for bolt connection between the first module, the second module, and the third module. Using bolts to pass through adjacent two threaded sleeves for fixed connection between the first module, the second module, or the third module is not only convenient for installation and fixation, but also the bolt connection can ensure the airtightness of the formwork after splicing.
[0015] Further, the diameter of each bolt is 10 mm.
[0016] The utility model discloses a multi - quantity sleeve sealing die assembly, and its beneficial effects are as follows:
[0017] In the utility model, a plurality of first modules, second modules and third modules are spliced into a sealing template on multiple sleeves. Since the first through - hole and the second through - hole for the sleeve to pass through are both spliced, they can undergo a certain deformation by using the fixing force between them, so as to fit more tightly with the sleeve, improve the compactness, avoid the situation of slurry leakage, reduce the risk of mold explosion, and due to the modular design, it can be reused.

For those ordinary skilled in the art of this technology, as long as various changes are within the spirit and scope of the utility model defined and determined by the appended claims, these changes are obvious, and all utility models created using the concept of the utility model are within the scope of protection.
[0026] Refer to Figure 1 and Figure 2 , this embodiment provides a multi - quantity sleeve sealing die assembly, including two opposing and parallel - arranged sealing templates 1.
[0027] Each sealing template 1 is evenly provided with a plurality of first through holes 11 and second through holes 12 for the sleeve 7 to pass through. The diameters of the first through hole 11 and the second through hole 12 are both the same as the diameter of the sleeve 7.
[0028] Reference Figure 1 , the middle part of each sealing template 1 includes a plurality of first modules 3 and a plurality of second modules 2 that are detachably spliced with each other. The four corners of each sealing template 1 are four third modules 4, and the four third modules 4 are respectively detachably connected to the first module 3. Each first through hole 11 is formed by splicing two first modules 3, two second modules 2 and one third module 4. The four second through holes 12 are respectively located at the four corners of the sealing template 1, and each second through hole 12 is formed by splicing two first modules 3 and two second modules 2.
[0029] Specifically, referring to Figure 3 and Figure 4 , as the specific structures of the first module 3 and the second module 2, each first module 3 is an isosceles trapezoidal plate structure, and second rounded openings are respectively provided at both ends of the first module 3.
[0030] Each second module 2 is a square plate structure, and first rounded openings are respectively provided at the four corners of each second module 2.
[0031] The length of the short side of the first module 3 is equal to the length of the straight side of the second module 2. The length of the long side of the first module 3 is equal to the sum of the length of the straight side of the second module 2 and the diameter of the first rounded opening. The height of the first module 3 is the same as the radius of the second rounded opening.
[0032] The top and bottom of each second module 2 are respectively detachably connected to two first modules 3. Each first through hole 11 is respectively formed by splicing two adjacent first rounded openings and two adjacent second rounded openings. The second module 2 and the first module 3 are respectively a square plate structure and an isosceles trapezoidal plate structure, with simple structures, which are convenient for workers to splice and reduce the construction difficulty.
[0033] Specifically, referring to Figure 5 , as the specific structure of the third module 4, the four third modules 4 are all isosceles right triangle plates, and the hypotenuse of each third module 4 is a third rounded opening. The length of the straight side of the third module 4 is equal to the radius of the third rounded opening.
[0034] Each second through hole 12 is respectively formed by splicing one first rounded opening, two second rounded openings and one third rounded opening. The setting that the third module 4 is an isosceles right triangle plate is applicable to the four-corner area of the sealing template 1.
[0035] In this embodiment, the central angles of the first rounded opening, the second rounded opening and the third rounded opening are all 90°.
[0036] Specifically, as a specific detachable connection method between the first module 3, the second module 2, and the third module 4, refer to Figure 6 . Multiple threaded sleeves 5 that cooperate with bolts 6 are provided at the splicing joints on the surfaces of each first module 3, each second module 2, and each third module 4. Each threaded sleeve 5 is used for bolt 6 connection between the first module 3, the second module 2, and the third module 4, and the diameter of the bolt 6 is 10 mm. Using bolts 6 to pass through adjacent two threaded sleeves 5 for fixed connection between the first module 3, the second module 2, or the third module 4 is not only convenient for installation and fixation, but also the bolt 6 connection can ensure the airtightness of the formwork 1 after splicing.
[0037] In summary, the working principle of this solution is as follows:
[0038] Before construction, clean the debris on the surfaces of multiple sleeves 7.
[0039] During construction, splice multiple first modules 3, second modules 2, and third modules 4 on multiple sleeves 7 to form the formwork 1.
[0040] Since the first through-hole 11 and the second through-hole 12 for the sleeve 7 to pass through are both spliced, they can undergo a certain deformation using the force of mutual fixation, so as to fit more tightly with the sleeve 7, improving the density. Compared with using a foam plastic board or a wire mesh for formwork sealing, the installation of the formwork 1 is simpler, and the corresponding module fits better with the sleeve 7, avoiding the occurrence of slurry leakage. Moreover, the formwork 1 is a metal plate. The strength of the formwork 1 is higher than that of the foam plastic board, reducing the risk of formwork explosion, and due to the modular design, it can be reused.
