Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a quick-assembly and disassembly formwork structure for buildings. Background Technology

[0002] Concrete pouring is a crucial construction process in which well-mixed concrete is poured into a formwork through transportation, placement, vibration, and curing to form a predetermined structural shape. It directly affects the strength, durability, and appearance quality of concrete components. Concrete pouring is a systematic process that requires strict control over multiple aspects, including materials, equipment, processes, and curing, to ensure structural safety and reliability.

[0003] For example, application number CN202323647095.X describes a casting formwork for bridge construction, comprising: a right template; the right template has a left template fastened to its left side, and both the right and left templates have a limiting plate at their upper ends, the upper ends of which are inclined surfaces; the lower ends of the inner walls of both the right and left templates have limiting grooves, the upper ends of which are inclined surfaces; the vertical cut angle of the front side of the right template is 45°, and the vertical cut angle of the rear side of the left template is 135°; the formwork also includes fixing ears, which are evenly distributed on the front and rear sides of the left and right templates.

[0004] In the above cases, because there are no supporting components, the mold will easily tilt, and the connection between the templates will loosen due to uneven stress, resulting in gaps. Concrete has fluidity and a large weight when poured, and the template needs to withstand lateral pressure (especially when pouring walls and columns) and vertical loads. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments. Example

[0018] Reference Figure 1-5 This is the first embodiment of the present utility model, which discloses a quick-assembly and disassembly template structure for construction, including: a base 1 and an arc-shaped template 2. The arc-shaped template 2 is provided on the upper surface of the base 1. Several support structures 3 are arranged in an array on the arc surface of the arc-shaped template 2. The support structure 3 includes: an arc-shaped mounting block 4. An arc-shaped docking plate is fixedly connected to the upper surface of the arc-shaped mounting block 4. A U-shaped rotating sleeve 5 is fixedly installed on the arc surface of the arc-shaped mounting block 4. A round rod is rotatably connected to the vertical surface of the U-shaped rotating sleeve 5. A rectangular storage sleeve 6 is provided through the rod body of the round rod in the inner ring of the U-shaped rotating sleeve 5. An extension rod 7 is slidably connected to the inner ring of the rectangular storage sleeve 6. An annular rod is fixedly provided at the end of the extension rod 7 away from the rectangular storage sleeve 6. An L-shaped docking block 8 is fitted on the rod body of the annular rod.

[0019] L-shaped connecting block 8 is inserted into rectangular base plate 9. Rectangular groove 10 is provided on the upper surface of rectangular base plate 9. A pair of T-shaped moving blocks 11 are provided through the vertical surface of rectangular base plate 9. Connecting rods 12 are fixedly connected to the vertical surface of each T-shaped moving block 11. Guide strips are also provided on the vertical surface of the outer side of rectangular base plate 9. A pair of connecting pipes 13 are fixedly provided on the vertical surface of the pair of T-shaped moving blocks 11 away from the connecting rods 12. The arc surface of the connecting rods 12 is elastic and resilient, which is a known existing feature.

[0020] A rectangular plate is fixedly connected to the end of a pair of connecting pipes 13 away from the T-shaped moving block 11. A rectangular loading plate 14 is fixedly installed on the vertical surface of the rectangular plate away from the T-shaped moving block 11. A lead screw 15 is rotatably connected to the bottom surface inside the rectangular groove 10. A lifting ring 16 is fitted on the rod of the lead screw 15. A pair of symmetrical rectangular notches are opened on the arc surface of the lifting ring 16. Rotating rods are rotatably connected to the vertical surfaces opposite the rectangular notches. A rectangular bar 17 is connected to the rod of the rotating rod.

[0021] The end of the rectangular bar 17 away from the lead screw 15 is also rotatably connected to a rotating rod, which is also fixedly connected to an arc sleeve 18. The arc sleeve 18 is fixedly connected to a rectangular loading plate 14. A movable groove is also provided on the bottom surface inside the rectangular groove 10. A pair of T-blocks 19 are slidably connected on the movable groove. An L-shaped rod is also fixedly connected to the upper surface of the T-blocks 19. A rectangular baffle is provided on the bottom surface inside the movable groove, and a pair of memory springs are installed on the vertical surface of the rectangular baffle.

[0022] When in use, since the upper surface of the arc-shaped mounting block 4 is fixedly connected to the arc-shaped docking plate, the arc-shaped mounting block 4 is directly installed on the arc-shaped mold 2. Then, the rectangular base plate 9 is taken out, and the tip of the L-shaped docking block 8 is aligned with the rectangular sleeve set on the rectangular base plate 9. Because the arc surface of the docking rod 12 is elastic and resilient, when the docking rod 12 contacts the rectangular groove 10, the arc-shaped part of the docking rod 12 will contract due to the pressure applied by the thrust, thus entering the interior of the rectangular groove 10. Because the end of the rectangular groove 10 away from the L-shaped docking block 8 has a greater opening height than the height when it just enters the rectangular groove 10, the docking rod 12 will rebound due to the change in space after fully entering the rectangular groove 10, thus locking the rectangular base plate 9.

[0023] At this point, pull the extension rod 7. After stretching to the desired length, it can be temporarily fixed with screws. Then, take out the fixing nail 22 for installation.

[0024] When disassembling, simply twist the torsion bar. Since the torsion bar is connected to the lead screw 15, and the lead screw 15 is fitted with a lifting ring 16, when the lead screw 15 rotates, the lifting ring 16 will begin to descend. As the lifting ring 16 descends, the rectangular bar 17 will gradually become horizontal, thereby changing the distance between the pair of T-blocks 19. Because the rectangular sleeve has a notch (the entire surface is exposed), it can be removed directly after rotation. Example

[0025] Reference Figure 2 and 3 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a pair of symmetrical grooves 20 are provided on the upper surface of the rectangular base plate 9, and a T-shaped loading block 21 is slidably connected inside the grooves 20. A circular ring is provided through the upper surface of the T-shaped loading block 21, and a positioning pin 22 is slidably connected to the inner ring of the circular ring.

[0026] When using it, first follow the above process. First, determine the soil condition at the inner ring of the groove. When suitable soil is found, move the T-shaped loading block 21 and then install it with screws to achieve temporary fixation. Then take out the hammer and insert it for installation.

[0027] The remaining structure is the same as that in Example 1.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
