Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on 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.

[0028] The purpose of this invention is to provide a universal template and construction method for precast concrete components. The universal template for precast concrete components is versatile and can meet the precast requirements of flanges with different slopes.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] like Figures 1 to 3 As shown, this embodiment provides a universal template for precast concrete components, used to form a T-beam 100. It includes two universal template components, each of which includes at least one universal template structure. The universal template structures are arranged sequentially along the length direction. Each universal template structure includes a flange template structure, a partition template structure, and a support frame 16. A casting space is formed between the partition template structures of the two universal template structures. One end of the flange template structure is used to connect with one end of the partition template structure. The support frame 16 is provided with a first adjustment structure 6 and a second adjustment structure 7. The first adjustment structure 6 is used to adjust the slope of the flange template structure, and the second adjustment structure 7 is used to adjust the angle of the partition template structure.

[0032] Specifically, in this embodiment, the support frame 16 includes a support frame body and a first support beam 17 and a second support beam 18 disposed on the support frame body.

[0033] In this embodiment, the flange plate template structure includes a flange plate template body 1 and a flange plate template support 2. The flange plate template body 1 is mounted on the flange plate template support 2 and is used to contact the concrete. The material of the flange plate template body 1 allows it to bend when the first adjusting structure 6 adjusts the slope of the flange plate template structure and the angle of the partition plate template structure. The flange plate template support 2 is used to connect with the first adjusting structure 6. The partition plate template structure includes a partition plate template body 3 and a partition plate template support 4. The partition plate template body 3 is mounted on the partition plate template support 4 and is used to contact the concrete. The partition plate template support 4 is used to connect with the second adjusting structure 7. One end of the flange plate template body 1 extends into the groove 5 between the partition plate template body 3 and the partition plate template support 4 and can slide in the groove 5. One end of the flange plate template body 1 overlaps with one end of the partition plate template body 3, and the overlapping parts are in contact.

[0034] In this embodiment, the first adjustment structure 6 includes a first screw 8, a first nut 9, and a second nut 10. The first screw 8 is vertically arranged, and one end of the first screw 8 is hinged to the flange plate template bracket 2 through a hinge seat 11. The first screw 8 passes through the first support beam 17 on the support frame 16. The first nut 9 and the second nut 10 are respectively threaded to the first screw 8. The first nut 9 and the second nut 10 are respectively located on both sides of the first support beam 17, and a gasket 12 is provided between the first nut 9 and the first support beam 17, and between the second nut 10 and the first support beam 17. When the flange plate template structure needs to be adjusted upward, loosen the second nut 10 so that the second nut 10 moves downward along the axis of the first screw 8, and tighten the first nut 9 so that the upper end of the first screw 8 lifts the flange plate template structure upward; when the flange plate template structure needs to be adjusted downward, loosen the first nut 9 so that the first nut 9 moves upward along the axis of the first screw 8, and tighten the second nut 10 so that the upper end of the first screw 8 pulls the flange plate template structure downward.

[0035] In this embodiment, the second adjustment structure 7 includes a second screw 13, a third nut 14, and a fourth nut 15. The second screw 13 is horizontally arranged, and one end of the second screw 13 is hinged to the partition template bracket 4 through a hinge seat 11. The second screw 13 passes through the second support beam 18 on the support frame 16. The third nut 14 and the fourth nut 15 are threadedly connected to the second screw 13, respectively. The third nut 14 and the fourth nut 15 are located on both sides of the second support beam 18, and a gasket 12 is provided between the third nut 14 and the second support beam 18, and between the fourth nut 15 and the second support beam 18. When the partition template structure needs to be adjusted outward, loosen the fourth nut 15, causing it to move outward along the axis of the second screw 13, and tighten the third nut 14, causing the inner end of the second screw 13 to pull the flange template structure outward. When the partition template structure needs to be adjusted inward, loosen the third nut 14, causing it to move inward along the axis of the second screw 13, and tighten the fourth nut 15, causing the inner end of the second screw 13 to push the flange template structure inward. In this embodiment, "inward" refers to approaching the pouring space, and "outward" refers to moving away from the pouring space.

[0036] In this embodiment, the slope of the flange template structure can be adjusted by the first adjustment structure 6, so that the template can meet the requirements of different flange slopes. The angle of the partition template structure can be adjusted by the second adjustment structure 7, so that the template can meet the requirements of different partition template structure angles. This embodiment is universal.

[0037] Example 2

[0038] The difference between this embodiment and Embodiment 1 is that in this embodiment, the first adjustment structure 6 is a first telescopic structure. One end of the first telescopic structure is used to connect with the flange template structure, and the other end of the first telescopic structure is used to connect with the support frame 16. The slope of the flange template structure can be adjusted by telescopically extending and retracting the first telescopic structure.

[0039] In this embodiment, the second adjustment structure 7 is a second telescopic structure. One end of the second telescopic structure is used to connect with the partition template structure, and the other end of the second telescopic structure is used to connect with the support frame 16. The angle of the partition template structure can be adjusted by the extension and retraction of the second telescopic structure.

[0040] In this embodiment, the first telescopic structure and the second telescopic structure can be driven structures such as cylinders or hydraulic cylinders that can achieve telescopic extension in a linear direction.

[0041] Example 3

[0042] like Figure 4 As shown, this embodiment provides a construction method for a universal formwork for precast concrete components according to Embodiment 1, including the following steps:

[0043] Step 1: Determine the predetermined requirements for the slope of the flange plate formwork structure and the angle of the diaphragm formwork structure;

[0044] Step two: Adjust the first adjustment structure 6 and the second adjustment structure 7;

[0045] Specifically, the slope adjustment of the flange plate template structure includes: when the flange plate template structure needs to be adjusted upward, the second nut 10 is loosened, causing the second nut 10 to move downward along the axis of the first screw 8, so that the upper end of the first screw 8 lifts the flange plate template structure upward; when the flange plate template structure needs to be adjusted downward, the first nut 9 is loosened, causing the first nut 9 to move upward along the axis of the first screw 8, so that the upper end of the first screw 8 pulls the flange plate template structure downward.

[0046] The angle adjustment of the partition template structure includes: when the partition template structure needs to be adjusted outward, loosening the fourth nut 15, causing the fourth nut 15 to move outward along the axis of the second screw 13, causing the inner end of the second screw 13 to pull the flange template structure outward; when the partition template structure needs to be adjusted inward, loosening the third nut 14, causing the third nut 14 to move inward along the axis of the second screw 13, causing the inner end of the second screw 13 to push the flange template structure inward.

[0047] Step 3: Check whether the slope of the flange plate template structure and the angle of the partition plate template structure meet the predetermined requirements. If they do not meet the requirements, repeat Step 2 until the slope of the flange plate template structure and the angle of the partition plate template structure meet the predetermined requirements.

[0048] Step four: Lock the first nut 9 or the second nut 10 of the first adjusting structure 6 and the third nut 14 or the fourth nut 15 of the second adjusting structure 7.

[0049] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
