Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a prestressed concrete pipe pile forming mold. Background Technology

[0002] Prestressed concrete is a building material that improves the load-bearing capacity and durability of concrete structures by applying pressure in advance. Materials such as steel bars or wires are tensioned before the concrete is poured and then fixed so that the concrete is compressed during the hardening process. When the concrete bears the actual load, it is in a state of compression, thereby reducing the generation and propagation of cracks and enhancing the overall performance of the structure.

[0003] The announcement CN221249307U describes a prestressed concrete pipe pile forming mold, comprising a lower outer mold, an outer mold, an inner mold, a lower inner mold, and a base plate. The upper part of the lower outer mold is fitted with the base plate, which is fixedly connected to the lower inner mold via hexagonal screws. A support column is fixed to the upper part of the base plate. A second limiting hole is provided at a corresponding position between the lower inner mold and the lower outer mold, and a first limiting rod is placed inside the second limiting hole. An outer mold is placed at the upper part of the lower outer mold, and an inner mold is fitted inside the outer mold. A first limiting hole is provided at a corresponding position between the outer mold and the inner mold, and a second limiting rod is placed inside the first limiting hole. A pouring device is fixed to the upper part of the outer mold via screws. This invention allows for the pouring of prestressed concrete pipe piles of different specifications by replacing the inner mold, lower inner mold, and support column with different specifications.

[0004] When prestressed concrete is poured using pipe pile molds, multiple screws are usually used to fix the molds together. This makes it difficult to assemble or disassemble the molds, which may increase the preparation time for each pour and thus affect the overall construction time. At the same time, the pressure or temperature changes brought about by the pouring may cause damage due to external pressure and internal stress. Since the molds are of a specific length, they are not easy to extend and require operators to spend a long time adjusting them. Utility Model Content

[0005] The purpose of this utility model is to provide a prestressed concrete pipe pile forming mold to solve the problems mentioned in the background art, which currently uses screws to splice the molds together, making it difficult to splice or disassemble, resulting in increased preparation time for each pour.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a prestressed concrete pipe pile forming mold, including: a lower mold 1, an upper mold 2, a first mating lug 3, a second mating lug 4, a guide hole 5, a guide rod 6, a limiting rod 7, a spring 8, a mounting bracket 9, a threaded rod 10, a fixing plate 11, a first reinforcing hoop 12, a second reinforcing hoop 13, and a bolt 14.

[0029] First, as attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 6 As shown, when prestressed concrete is poured into pipe piles through lower mold 1 and upper mold 2, the length between lower mold 1 and upper mold 2 is first extended according to the required pouring length. Since the front end of lower mold 1 has guide holes 5, and three sets of guide holes 5 are arranged in a circular array about the center point of lower mold 1, and the front end of upper mold 2 also has guide holes 5, guide rods 6 are fixedly installed at the rear end of lower mold 1, and three sets of guide rods 6 are arranged in a circular array about the center point of lower mold 1. Guide rods 6 are also fixedly installed at the rear end of upper mold 2. Then, with the guide holes 5 and guide rods 6 corresponding to each other, one set of guide rods 6 at the rear end of lower mold 1 and upper mold 2 is inserted into the interior of the front guide holes 5 of another set of lower mold 1 and upper mold 2. Since a limiting rod 7 is slidably connected to the outside of lower mold 1, and the limiting rod 7 is about the center point of lower mold 1... The upper mold 2 has three sets of central dots arranged in a circular array. The outer side of the upper mold 2 is also slidably connected to the limiting rod 7. The limiting rod 7 extends through the outer side of the lower mold 1 and the upper mold 2 into the interior of the lower mold 1 and the upper mold 2. The outer side of the limiting rod 7 with respect to the inner cavity of the lower mold 1 and the upper mold 2 is sleeved with a spring 8. When the guide rod 6 is inserted into the guide hole 5, the limiting rod 7 can be pulled, thereby causing the limiting rod 7 to drive the spring 8 to compress. Since the length of the guide rod 6 is consistent with the depth of the guide hole 5, the guide rod 6 is completely placed inside the guide hole 5. At the same time, the elastic force of the spring 8 drives the limiting rod 7 to reset and engage with the guide rod 6. This splices one set of lower mold 1 and upper mold 2 with another set of lower mold 1 and upper mold 2 together, extending its length. The length can be adjusted according to the needs, which also reduces the adjustment time of the operator.

[0030] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5As shown in the figure, when the pouring lengths of the lower die 1 and the upper die 2 are extended, the lower die 1 is then placed at the designated position, and the upper die 2 is placed above the lower die 1. Then, the first docking ears 3 at the left and right ends of the lower die 1 and the second docking ears 4 at the left and right ends of the upper die 2 are arranged in a corresponding state. At the same time, an installation groove is formed on the plate body of the second docking ear 4, and the first docking ear 3 is arranged in a "convex" shape structure. When the upper die 2 is placed above the lower die 1, the first docking ear 3 is placed in the installation groove of the second docking ear 4, and the first docking ear 3 is engaged with the second docking ear 4. Then, an installation frame 9 is rotatably connected inside the first docking ear 3, and the installation frames 9 are arranged in an array state with respect to the horizontal line of the first docking ear 3. At the same time, a threaded rod 10 is rotatably connected to the frame body of the installation frame 9, and a fixing plate 11 is slidably connected to the rod body of the threaded rod 10. Thus, the threaded rod 10 and the fixing plate 11 are initially placed inside the first docking ear 3. Then, by rotating the installation frame 9, the fixing plate 11 can be flipped by the threaded rod 10. Furthermore, the threaded rod 10 is rotated to extend above the second docking ear 4. At the same time, the inner side wall of the fixing plate 11 is threadedly connected to the threaded rod 10. Since through holes are formed at the left and right ends of the bottom of the fixing plate 11, and convex blocks are arranged at the left and right ends of the plate body of the second docking ear 4, the fixing plate 11 is held by hand and the threaded rod 10 is rotated, so that the threaded rod 10 drives the installation frame 9 to rotate inside the first docking ear 3, and then the fixing plate 11 descends to be engaged with the convex blocks on the plate body of the second docking ear 4, so that the lower die 1 and the upper die 2 are spliced together. At the same time, by reversing the threaded rod 10, the splicing between the lower die 1 and the upper die 2 can be conveniently released, so that the replacement and adjustment time of the lower die 1 and the upper die 2 can be significantly shortened through a simple and convenient splicing and disassembly process;

[0031] As shown in the attached Figure 3 and attached Figure 4 As shown in the figure, when the lower die 1 and the upper die 2 are spliced together, the first reinforcing hoop 12 can be sleeved on the left end of the outer sides of the lower die 1 and the upper die 2, and the second reinforcing hoop 13 is also placed on the right end of the outer sides of the lower die 1 and the upper die 2. Then, the first reinforcing hoop 12 and the second reinforcing hoop 13 are fixed together by bolts 14. The splicing between the first reinforcing hoop 12 and the second reinforcing hoop 13 can reinforce the lower die 1 and the upper die 2, provide additional support force, effectively prevent deformation under high pressure and high temperature conditions, and ensure that the lower die 1 and the upper die 2 maintain their original shapes.
