Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a positioning clamp for reinforcing bars and casting formwork. Background Technology

[0002] Currently, in reinforced concrete engineering, it is necessary to tie the reinforcing bars and pour concrete. During the pouring process, pouring formwork is needed to enclose the pouring area. Because the reinforcing bars are prone to displacement during tying and pouring, workers need to make positioning clamps on-site using discarded reinforcing bars to position them.

[0003] However, the precision of the positioning clamps made on-site is difficult to control, and the dimensional deviation is large, which affects the positioning accuracy of the steel bars and increases the burden on the staff. The positioning clamps cannot be reused, resulting in a waste of resources, which needs to be improved. Utility Model Content

The fastening screw at the corresponding end of each first clamping plate can be threaded to any of the fastening grooves on the corresponding second clamping plate, so that the distance between the two first clamping plates can be adjusted.

[0008] Optionally, each of the first and second plates is provided with a limiting plate vertically, and the four limiting plates abut against each other and can form an abutment limiting with the outer side of the casting template.

[0009] Optionally, the limiting plate is integrally formed and connected with the corresponding first or second clamping plate.

[0010] Optionally, each of the limiting plates is provided with multiple bolt holes so that the casting template can be connected to the limiting plate by fastening bolts.

[0011] Optionally, the surfaces of the first card plate, the second card plate, and the limiting plate are respectively provided with an anti-rust layer.

[0012] In summary, this utility model has at least the following beneficial effects:

[0013] This positioning clamp improves the positioning accuracy of reinforcing bars and eliminates the need for on-site fabrication, reducing the workload for workers.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figure 1 , Figure 2 , Figure 3 A positioning clamp for reinforcing bars and casting formwork includes two horizontally and parallelly arranged first clamping plates 1. The positioning clamp also includes two horizontally and parallelly arranged second clamping plates 2, and the two first clamping plates 1 and the two second clamping plates 2 are arranged perpendicularly.

[0020] Reference Figure 1 , Figure 2 , Figure 3The two ends of the two first clamping plates 1 overlap the corresponding second clamping plates 2, and the two ends of each first clamping plate 1 are connected to the corresponding second clamping plate 2 by fastening screws 3, so that the two first clamping plates 1 and the two second clamping plates 2 form a rectangular frame structure. Each first clamping plate 1 and the second clamping plate 2 is provided with a positioning notch 4 for inserting the reinforcing bar, so as to realize the positioning of the reinforcing bar.

[0021] Reference Figure 1 , Figure 2 , Figure 3 Each of the first clamping plate 1 and the second clamping plate 2 is fixedly connected with a bolt lug 5 through which the fastening bolt passes. That is, the bolt lug 5 can be connected to the external building through the fastening bolt, thereby realizing the fixation of the first clamping plate 1 and the second clamping plate 2 to the external building, thus improving the positioning effect of the reinforcing bar.

[0022] The bolt lugs 5 on the two second clamping plates 2 are respectively fixed to the external building with fastening bolts, ensuring that the reinforcing bars are inserted into the positioning notches 4 on the second clamping plates 2. Then, the two ends of the two first clamping plates 1 are respectively fixed to the corresponding second clamping plates 2 with fastening screws 3, ensuring that the reinforcing bars are inserted into the positioning notches 4 on the first clamping plates 1.

[0023] Subsequently, the bolt lugs 5 on the two first clamping plates 1 are fixed to the external building structure with fastening bolts. At this point, the reinforcing bars are positioned, and then the reinforcing bars can be tied. Next, the bottom of the pouring formwork is placed against the first clamping plate 1 and the second clamping plate 2, and then the pouring formwork is fixed, and then the pouring operation can be carried out. After the workers disassemble the pouring formwork, the first clamping plate 1 and the second clamping plate 2 can be disassembled so that the positioning clamps can be reused.

[0024] Compared to on-site positioning devices made by workers, the positioning clamp in this embodiment is more accurate and reliable, thereby improving the positioning accuracy of the rebar. This positioning clamp eliminates the need for on-site fabrication, reducing the workload of workers. Furthermore, the positioning clamp is reusable, improving resource utilization efficiency.

[0025] Reference Figure 1 , Figure 2 , Figure 3 The fastening screws 3 are threaded to the corresponding ends of the two first clamping plates 1, meaning that each end of the first clamping plate 1 is threaded with a fastening screw 3. Each of the two second clamping plates 2 has a row of fastening grooves 6, and the two rows of fastening grooves 6 are equally spaced along the length of the second clamping plate 2. Simultaneously, the fastening screws 3 at the corresponding ends of each first clamping plate 1 can be threaded into any fastening groove 6 on the corresponding second clamping plate 2, allowing the distance between the two first clamping plates 1 to be adjusted. This enables the positioning clamp to adapt to buildings of different lengths, improving its usability.

[0026] Reference Figure 1 , Figure 2 , Figure 3 Each first card plate 1 and second card plate 2 is vertically provided with a limiting plate 7. The four limiting plates 7 abut against each other and form a rectangular frame structure. At the same time, the outer side of the casting template abuts against the first card plate 1 and the second card plate 2 to limit the casting template, thereby reducing the risk of casting template displacement and ensuring casting quality.

[0027] Reference Figure 1 , Figure 2 , Figure 3 The limiting plate 7 is integrally formed and connected with the corresponding first clamping plate 1 or second clamping plate 2 to improve the structural stability between the limiting plate 7 and the first clamping plate 1 or second clamping plate 2, thereby enhancing the limiting effect on the casting template. Simultaneously, each limiting plate 7 is provided with multiple bolt holes 8, allowing the casting template to be connected to the limiting plate 7 via fastening bolts, thus improving the connection stability between the casting template and the limiting plate 7.

[0028] Reference Figure 1 , Figure 2 , Figure 3 The surfaces of the first clamping plate 1, the second clamping plate 2, and the limiting plate 7 are respectively provided with anti-rust layers (not shown in the figure) to improve the anti-rust ability of the first clamping plate 1, the second clamping plate 2, and the limiting plate 7, thereby improving the service life of the positioning fixture.
