Description

Technical Field

[0001] This utility model relates to the field of bottom reinforcement binding technology for heavy beams, specifically a reinforcement binding auxiliary support. Background Technology

[0002] In the construction of bottom reinforcement binding for super-heavy beams, the existing technology mainly has the following problems:

[0003] 1. Limited operating space: When tying reinforcing bars, it is necessary to manually enter the narrow interior of the heavy beam mold, resulting in limited construction space, low tying efficiency and inconvenience in operation;

[0004] 2. Difficulty in positioning reinforcing bars: Traditional methods lack effective positioning tools, and the spacing of reinforcing bars is prone to deviation, affecting the accuracy of the structure;

[0005] 3. Risk of exposed rebar: After being tied, the rebar is in direct contact with the inner wall of the mold. When the formwork is removed after pouring concrete, the rebar is easily exposed, which not only increases the risk of corrosion, but also reduces the thickness of the concrete cover, affecting the structural durability and load-bearing capacity.

[0006] Therefore, we propose an auxiliary support for rebar tying. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an auxiliary support for rebar tying, which has the following beneficial effects:

[0018] 1. This type of rebar tying auxiliary support allows for precise positioning and tying of rebars outside the mold via rebar positioning holes on the support frame. This avoids workers entering the narrow interior of the mold to operate, significantly improving construction efficiency and reducing labor intensity.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] This embodiment is an auxiliary support for rebar tying.

[0030] like Figure 1-6 As shown, the support frame includes a support frame 1. A steel bar positioning hole 2 is provided on the upper part of the outer surface of one side of the support frame 1. A second slot 11 is provided on the lower outer surface of the support frame 1. A second threaded hole 9 is provided on the lower part of the outer surface of one side of the support frame 1. One end of the second threaded hole 9 is connected to the second slot 11. A snap-fit ​​hole 4 is provided in the middle of the left and right ends of the outer surface of the front end of the support frame 1. A first slot 3 is provided in the middle of the outer surface of the left end of the support frame 1. A snap-fit ​​assembly 6 is fixedly installed in the middle of the outer surface of the right end of the support frame 1. The snap-fit ​​hole 4 is connected to the first slot 3. The snap-fit ​​assembly 6 includes a plug block 12, a mounting cavity 13, a compression spring 14, a through hole 15, a limiting block 16, and a snap-fit ​​post 17. A concrete pad 5 is provided at the lower end of the support frame 1. A plug block 7 is fixedly installed in the middle of the outer surface of the upper end of the concrete pad block 5. A first threaded hole 8 is provided on the upper part of the outer surface of one side of the plug block 7. A fixing bolt 10 is provided between the plug block 7 and the support frame 1.

[0031] The outer wall of the insert block 7 is inserted into the second slot 11; the fixing bolt 10 is threaded between the second threaded hole 9 and the first threaded hole 8; the insert block 12 is fixedly installed in the middle of the outer surface of the right end of the support frame 1, the through hole 15 is opened in the middle of the outer surface of the front end of the insert block 12, the snap-fit ​​post 17 passes through the through hole 15, the mounting cavity 13 is opened inside the insert block 12, the compression spring 14 and the limiting block 16 are both located in the mounting cavity 13, the compression spring 14 is fixed between the end of the mounting cavity 13 away from the through hole 15 and the outer surface of the limiting block 16 on one side; the snap-fit ​​post 17 is fixedly installed. At the middle of the outer surface of the other side of the limiting block 16, the outer wall of the limiting block 16 is slidably connected to the mounting cavity 13. One side of the outer surface of the limiting block 16 is elastically connected to one end of the mounting cavity 13 through the compression spring 14. The outer wall of the snap-fit ​​post 17 is slidably connected to the through hole 15. The outer wall of the plug-in block 12 is connected to the first slot 3 of the adjacent support frame 1 through plug-in cooperation to realize the lateral connection of multiple sets of support frames 1. Under the elastic force of the compression spring 14, the snap-fit ​​post 17 is snapped into the snap-fit ​​hole 4 of the adjacent support frame 1, thereby completing the rapid assembly and fixation between multiple sets of support frames 1.

[0032] It should be noted that this utility model is a rebar tying auxiliary support. The support frame 1 is provided, and when splicing support frames 1, a snap-fit ​​component 6 is provided. By pressing the snap-fit ​​post 17 in the snap-fit ​​component 6, the snap-fit ​​post 17 slides along the through hole 15. The snap-fit ​​post 17 drives the limiting block 16 to press the compression spring 14 in the mounting cavity 13, causing one end of the snap-fit ​​post 17 to enter the through hole 15. Then, the insertion block 12 in one end of the snap-fit ​​component 6 of one set of support frames 1 is inserted into the first slot 3 of another set of support frames 1. When the snap-fit ​​post 17 reaches one end of the snap-fit ​​hole 4, the reaction force of the compression spring 14 causes one end of the snap-fit ​​post 17 to snap into the snap-fit ​​hole 4, realizing the splicing of the two sets of support frames 1. After installation, the reinforcing bars are passed through the reinforcing bar positioning holes 2 in the support frame 1 (the position of the reinforcing bar positioning holes 2 in the support frame 1 is customized according to the spacing between the reinforcing bars on the design drawings). After the reinforcing bars pass through the reinforcing bar positioning holes 2 in the support frame 1, they serve as positioning tools. Then, the reinforcing bars perpendicular to the reinforcing bar positioning holes 2 are placed on the reinforcing bars passing through the reinforcing bar positioning holes 2 and then tied. This allows the reinforcing bars to be tied outside the mold. After that, the tied reinforcing bars are placed into the mold. Concrete spacers 5 are set and installed on the lower outer surface of the support frame 1. When pouring concrete, the concrete spacers 5 provide support and separate the reinforcing bars from the mold, preventing the reinforcing bars from being exposed on the outside after pouring concrete and improving the quality of the heavy beam.
