Description

Technical Field

[0001] This utility model belongs to the technical field of template support rods, specifically relating to a telescopic support rod for supporting templates on H-shaped steel beams. Background Technology

[0002] In the construction of steel-concrete structures, support rods are typically used to fix the steel beams to the H-beams, and then wooden planks are placed on the support rods. This allows for the binding of reinforcing bars and the pouring of concrete.

[0003] Since most existing support rods are installed on H-beams by cutting timber, the installation of the support rods is cumbersome and wasteful of timber, which is not economical or convenient. It is also not easy to dismantle them quickly after the concrete is poured, which is not conducive to rapid turnover.

[0004] Therefore, a telescopic support rod for supporting formwork on H-beams is proposed. Summary of the Invention

[0005] This utility model provides a telescopic support rod for supporting templates on H-shaped steel beams, the purpose of which is to solve the problems mentioned above.

[0006] This utility model embodiment provides a retractable support rod for supporting templates on H-shaped steel beams, including a square tube one and a square tube two, one end of which is embedded inside the square tube one; a square tube telescopic assembly disposed at the top of the square tube one and the square tube two; the square tube telescopic assembly includes: a toothed plate fixed to the top of the square tube two by screws; a toothed seat fixed to the top of the square tube one by screws; a toothed groove formed at the top of the toothed plate; a handle rotating on the inner side wall of the toothed seat; an arcuate platform fixed to one side of the bottom of the handle; a gear tooth disposed on one side of the outer wall of the arcuate platform; a buckle post disposed on the outer side of the arcuate platform adjacent to the gear tooth; a groove formed on one side of the inner wall of the toothed seat; a safety buckle rotating on the inner side wall of the groove, with a torsion spring disposed between the outer side wall of the safety buckle and the inner side wall of the groove; and support leg telescopic assemblies disposed at the top one side of the square tube one and the square tube two, the square tube telescopic assembly and the support leg telescopic assembly having the same structure.

[0007] Furthermore, a through groove is provided at the bottom of the first square tube, and an equal-height pad is welded to the bottom of the second square tube near the inner side of the through groove. Rubber pads are provided on one side of the bottom of the equal-height pad and one side of the bottom of the first square tube.

[0008] Furthermore, the toothed plate passes through the tooth holder, and the tooth groove and the gear teeth are meshed together;

[0009] By adopting the above technical solution, the meshing connection can ensure that the handle is locked in place with the toothed plate, preventing the toothed plate from loosening, thereby realizing the adjustment of the length of the combined square tube one and square tube two, and thus adjusting the length of the support rod.

[0010] Furthermore, a protrusion is provided on one outer wall of the safety buckle, and the safety buckle and the buckle post are engaged and connected.

[0011] By adopting the above technical solution, the protrusion facilitates the rotation of the safety buckle, thereby facilitating the separation of the safety buckle and the buckle post.

[0012] Furthermore, the bottom of the equal-height pad and the bottom of the square tube are on the same plane;

[0013] By adopting the above technical solution, it is ensured that square tube 2 and square tube 1 can be stably supported.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model uses a support leg telescopic assembly and a square tube telescopic assembly to fix the support rod to the H-shaped steel beam. By adjusting its length, the length of the combined square tube one and square tube two can be adjusted through the square tube telescopic assembly. This allows the support rod to be adaptively adjusted according to the spacing between adjacent H-shaped steel beams, ensuring the stability and firmness of the adjusted length. It is easy to disassemble after the concrete is poured and can be applied to the next construction site, achieving rapid and convenient turnover.

[0024] To make the objectives, technical solutions, and advantages 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. The same reference numerals in the drawings represent the same components. It should be noted that 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 described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1-5This utility model embodiment proposes a telescopic support rod for supporting templates on H-shaped steel beams, including a square tube 1 and a square tube 2. One end of the square tube 2 is embedded inside the square tube 1. The top of the square tube 2 is fixedly connected to a toothed plate 31 in a square tube telescopic assembly 3 by screws. The top of the square tube 1 is fixedly connected to a toothed seat 32 by screws. The top of the toothed plate 31 has a toothed groove 33, which passes through the toothed seat 32. The toothed groove 33 and the toothed tooth 36 are meshed together. The meshing connection ensures that the handle 34 engages and locks with the toothed plate 31, preventing the toothed plate 31 from loosening. This allows for adjustment of the length of the combined square tube 1 and square tube 2, thereby adjusting the length of the support rod. The handle 34 is rotatably connected to the inner wall of the toothed seat 32. An arcuate platform 35 is provided at one end of the bottom of the handle 34. A gear tooth 36 is provided on one outer wall of the arcuate platform 35, and a latch 37 is provided on the outer wall of the arcuate platform 35 adjacent to the gear tooth 36. The inner side of the toothed seat 32... A groove 38 is provided on the wall near the lower part of the buckle post 37. A safety buckle 39 is rotatably connected to the inner side wall of the groove 38. A protrusion is provided on one outer wall of the safety buckle 39, and the safety buckle 39 and the buckle post 37 are engaged. The protrusion facilitates the rotation of the safety buckle 39, thereby facilitating the separation of the safety buckle 39 and the buckle post 37. A torsion spring is provided between one outer wall of the safety buckle 39 and one inner wall of the groove 38. Both square tube 1 and square tube 2 have a top end on one side. The support leg telescopic assembly 4 has the same structure as the structure composed of square tube 1, square tube 2 and square tube telescopic assembly 3. The bottom of square tube 1 is provided with a through groove 6. The bottom of square tube 2 is welded with a leveling plate 7 near the inner side of the through groove 6. Rubber pads 5 are provided on one side of the bottom of leveling plate 7 and one side of the bottom of square tube 1. The bottom of leveling plate 7 and the bottom of square tube 1 are on the same plane, ensuring that square tube 2 and square tube 1 can be stably supported.

[0026] The specific implementation method is as follows: When installing square tube 1 and square tube 2, adjust the combined length of square tube 1 and square tube 2 according to the spacing between adjacent H-shaped steel beams. Push the safety buckle 39 to rotate. After the safety buckle 39 separates from the buckle post 37, rotate the handle 34 180 degrees. The arc platform 35 and the gear tooth 36 make a circular motion with the rotation of the handle 34. The gear tooth 36 separates from the tooth groove 33. After the tooth plate 31 loses its limit, pull the square tube 2 to adjust the combined length of square tube 1 and square tube 2, so that one end of square tube 1 and square tube 2 respectively contacts the adjacent H-shaped steel beam. At this time, rotate the handle 34 180 degrees in the opposite direction. The gear tooth 36 inserts into the tooth groove 33. The safety buckle 39 is then released by the rebound force of the torsion spring. Under the action of the buckle 37, the safety buckle 39 limits the rotation of the handle 34, thereby realizing the length adjustment of square tube 1 and square tube 2, thus ensuring that the support rod is telescopic. Similarly, the height of the support rod is adjusted by using the support leg telescopic component 4. First, the bottom end of the support leg telescopic component 4 is placed on the lower flange of the H-shaped steel beam. The height of the support leg telescopic component 4 is adjusted by the above method, so that the rubber pad 5 on the square tube 1 and the equal height plate 7 fully presses against the upper flange of the H-shaped steel beam, so that one end of the square tube 1 and square tube 2 is fixed on the H-shaped steel beam. Then, the support template is placed on the square tube 1 and square tube 2, so that the steel reinforcement can be tied and the concrete poured.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
