Technical Field

[0001] This utility model belongs to the field of basic construction technology, and in particular relates to a rebar laying, binding and positioning device. Background Technology

[0002] Wind turbine foundations are massive, with diameters reaching tens of meters. Rebar tying is a crucial step in wind turbine foundation construction, especially the arc-shaped arrangement of rebar tying. Currently, in wind turbine foundation construction, the arc-shaped arrangement of rebar tying requires continuous manual measurement of the rebar positions to ensure that the spacing between the rebars meets construction requirements. However, due to the large construction area and the large errors in manual positioning, if the rebar arrangement is too dense or too sparse when tying the outermost ring of rebars, it is necessary to readjust and tying the rebars in the overly dense or sparse areas, which is time-consuming, labor-intensive, and reduces construction efficiency.

Detailed Implementation

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

[0018] Example 1 A typical embodiment of this utility model is as follows: Figure 1 As shown, a rebar laying, binding and positioning device includes a base frame 1 and several rebar clamps 2. The several rebar clamps 2 are fixed side by side at the bottom of the base frame 1 along the length direction of the base frame 1. There is a set distance between two adjacent rebar clamps 2. A fixing groove 3 is opened on the bottom surface of the rebar clamp 2 for fixing the rebar.

[0019] Specifically, such as Figure 2 and Figure 3 As shown, the base frame 1 is a plate-shaped structure. The length of the base frame 1 is set according to the construction requirements. Several slots 4 are opened at the bottom of the base frame 1. The slots 4 are evenly arranged along the length of the base frame 1, and there is a set distance between two adjacent slots 4. A rebar holder 2 is inserted into the slot 4. Both the slot 4 and the rebar holder 2 are trapezoidal. The thickness of the rebar holder 2 is greater than the thickness of the slot 4. Limiting plates 5 are symmetrically arranged on both sides of the side wall of the rebar holder 2. The two limiting plates 5 are parallel to each other, and the distance between the two limiting plates 5 is equal to the thickness of the base frame 1. When the rebar holder 2 is inserted into the slot 4, the two limiting plates 5 are located on both sides of the base frame 1 and are in contact with the side walls of the base frame 1. Thus, the limiting plates 5 limit the rebar holder 2 and prevent the rebar holder 2 from shaking.

[0020] The bottom of the rebar holder 2 is provided with a fixing groove 3. The top of the fixing groove 3 is arc-shaped, which is adapted to the outer surface of the rebar and can fix the rebar. The bottom of the fixing groove 3 is trapezoidal and extends to both sides, thereby increasing the entrance width of the fixing groove 3 and making it easier for the rebar to enter the fixing groove 3.

[0021] Furthermore, the dimensions of the slot 4, the rebar holder 2, and the fixing slot 3 on them can be set according to the diameter of the rebar. Different base frames 1 and rebar holders 2 can be selected according to different rebar diameters to meet construction requirements.

[0022] The top surface of the rebar holder 2 is provided with a threaded hole 6, and the base frame 1 at the top of the slot 4 is provided with a through hole 7. The threaded hole 6 and the through hole 7 are set in correspondence. When the rebar holder 2 is inserted into the slot 4, the threaded hole 6 and the through hole 7 are connected. The bolt 8 is used to pass through the through hole 7 and be threadedly connected to the threaded hole 6 to realize the fixed connection between the rebar holder 2 and the base frame 1.

[0023] Furthermore, the rebar holder 2 is made of strong magnetic material, which can be attracted to the rebar during use to prevent it from falling into the rebar frame.

[0024] When using, such as Figure 4As shown, firstly, select the base frame 1 and the rebar clamp 2 according to the construction requirements. Fix the rebar clamp 2 in the groove 4 at the bottom of the base frame 1. Starting from the first ring of rebar at the center of the rebar laying, use it to clamp the adjacent ring of arc-shaped rebar radiating outward in sequence. Then, tie the positioned arc-shaped rebar. Compared with the traditional laying method of manually using pry bars and simple measurement, it can save the later adjustment work of the arc-shaped rebar, realize the one-time accurate positioning of rebar tying, and improve the laying and tying efficiency of arc-shaped rebar.

[0025] Example 2 Another embodiment of this utility model, such as Figure 5 As shown, a rebar laying, binding and positioning device includes a base frame 1 and several rebar clamps 2. The several rebar clamps 2 are fixed side by side at the bottom of the base frame 1 along the length direction of the base frame 1. A fixing groove 3 is opened on the bottom surface of the rebar clamp 2 for fixing the rebar.

[0026] Specifically, such as Figure 6 and Figure 7 As shown, the base frame 1 is a plate-shaped structure, and its length is set according to the construction requirements. A sliding groove 9 is provided on the base frame 1, which runs through the top and bottom surfaces of the base frame 1 and is opened along the length direction of the base frame 1. A slider 10 is provided on the top of the rebar holder 2. The height of the slider 10 is less than the height of the sliding groove 9, and the width of the slider 10 is the same as the width of the sliding groove 9, so that the slider 10 can be placed in the sliding groove 9 and can slide along the sliding groove 9. Multiple threaded holes 6 are provided on the top surface of the slider 10. When the slider 10 is placed in the sliding groove 9, the threaded holes 6 are connected to bolts 8, and the rebar holder 2 is fixed to the base frame 1 by the bolts 8.

[0027] Furthermore, a washer can be placed on the outside of the bolt 8. The washer is located between the bolt 8 nut and the upper surface of the base frame 1, thereby increasing the stress area on the upper surface of the base frame 1 and ensuring the firmness of the steel bar holder 2.

[0028] The bottom of the rebar holder 2 is provided with a fixing groove 3. The top of the fixing groove 3 is arc-shaped, which is adapted to the outer surface of the rebar and can fix the rebar. The bottom of the fixing groove 3 is trapezoidal and extends to both sides, thereby increasing the entrance width of the fixing groove 3 and making it easier for the rebar to enter the fixing groove 3.

[0029] In use, multiple steel bar holders 2 are placed on the base frame 1. Before fixing, the distance between two adjacent steel bar holders 2 is adjusted by using the slider 10 and the groove 9, so as to facilitate the adjustment of the spacing between the curved steel bars and meet different construction requirements.

[0030] By fixing multiple rebar holders on the base frame, with fixing grooves at the bottom of the rebar holders for fixing the rebars, in use, the first ring of rebars at the center of the rebar laying is used as a base, and the adjacent rings of arc-shaped rebars radiating outwards are clamped in sequence. Then the positioned arc-shaped rebars are tied. There is no need to make repeated adjustments when tying the arc-shaped rebars, which can achieve one-time accurate positioning of the rebars and improve the efficiency of laying and tying arc-shaped rebars.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
