[0002] There are many ditch covers in double-track tunnels, and the cover steel bars need to be tied. When tying the cover steel bars, due to the large workload and the uneven operating levels of the workers, some workers have different tying spacings, which affects the construction quality and progress. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a tunnel cover plate steel bar binding fixing mold, which accelerates the steel bar binding speed by fixing the cover plate steel bar grid size.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a tunnel cover steel bar binding and fixing mold, which consists of a steel bar limiting template frame, an adjustable limiting side plate, a steel bar limiting clamp, and a limiting baffle. The steel bar limiting template frame is U-shaped, including a long module arranged in parallel front and back and a short template vertically connected to the same side ends of the two long modules. The two long modules are arranged with multiple groups of limiting grooves at intervals along the length direction. The adjustable limiting side plate can dynamically adjust the installation position according to the limiting grooves reserved on the steel bar limiting template frame. The steel bar limiting template frame and the upper end surface of the adjustable limiting side plate are coplanar, and steel bar limiting clamps are evenly arranged according to the spacing of the cover plate steel bars. The limiting baffle is fixed on the adjacent two side modules of the steel bar limiting template frame. The limiting baffle is higher than the steel bars in the steel bar limiting clamp, and is used to limit and fix the position of the cover plate steel bars.

[0005] Furthermore, the limiting groove is vertically arranged on the inner side wall of the long module.

[0006] Furthermore, the steel bar limiting template frame and the adjustable limiting side panels are made of wooden materials.

[0007] Furthermore, the material of the steel bar limiting clamps is iron nails, and the spacing of the steel bar limiting clamps can be dynamically adjusted according to the model of the prefabricated cover plate steel bars.

[0008] Furthermore, the limiting baffle is made of wood material and is fixed on the back side of the steel bar limiting template frame.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The tunnel cover steel bar binding fixing mold of the utility model has a simple structure and is easy to operate. By arranging limiting grooves on both sides of the steel bar limiting template frame, the binding of cover steel bars of different sizes can be realized. The bound steel bars are limited by the steel bar limiting clamps to ensure the gap between the steel bar binding. Furthermore, one end of the steel bar is limited by the limiting baffle to ensure the horizontal and vertical positions of the steel bars to be bound, thereby improving the quality of steel bar binding construction and accelerating the construction progress.

[0013] In order to better understand the purpose, structure and function of the utility model, a tunnel cover steel bar binding and fixing mold of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0014] like Figure 1 As shown, a tunnel cover steel bar binding and fixing mold includes a steel bar limiting template frame 1 and an adjustable limiting side plate 2. The steel bar limiting template frame 1 is U-shaped, including a long module arranged in parallel in front and back and a short template vertically connected to the same side ends of the two long modules. The two long modules are provided with multiple groups of limiting grooves 4 at intervals along the length direction. Specifically, the limiting grooves 4 are vertically arranged on the inner side walls of the long modules. The steel bar limiting template frame 1 and the adjustable limiting side plate 2 are combined and connected by the limiting grooves 4. The position of the adjustable limiting side plate 2 can be dynamically adjusted by the limiting grooves 4 on the steel bar limiting template frame 1, which is suitable for the steel bar binding of prefabricated cover plates of different sizes.

[0015] The upper end surfaces of the steel bar limiting template frame 1 and the adjustable limiting side plate 2 are coplanar, and steel bar limiting fixtures 3 are evenly arranged according to the spacing of the cover plate steel bars, which are used to fix the spacing of the prefabricated cover plate steel bars. The limiting baffle 5 is fixed on the back of the adjacent modules on both sides of the steel bar limiting template frame 1. The limiting baffle 5 is higher than the steel bars in the steel bar limiting fixture 3, and is used to limit one end of the steel bar to ensure the horizontal and vertical positions of the tied steel bars.

[0016] In this embodiment, the steel bar limiting template frame 1 and the adjustable limiting side plate 2 are made of wooden materials, and the steel bar limiting clamps 3 are made of iron nails. The spacing of the steel bar limiting clamps 3 can be dynamically adjusted according to the prefabricated cover plate steel bar model. The limiting baffle 5 is also made of wooden material and is fixed on the back of the steel bar limiting template frame 1.

[0017] The utility model provides a tunnel cover steel bar binding fixing mold. The clamps around the mold are used to limit the binding steel bars, thereby ensuring the gap of the steel bar binding, overcoming the problem of large mesh size error of the cover steel bar, slow manual binding speed and low efficiency; in addition, two baffles are added to limit one end of the steel bar, thereby ensuring the position of the steel bar to be tied, which is conducive to improving the work efficiency. The device has a simple structure, low production cost and convenient operation, and is suitable for the steel bar binding construction of prefabricated tunnel ditch cover.
