At the same time, the steel mesh is also required to be flat and vertical. However, it is difficult for the support structure of the prior art to adjust the state of the steel mesh, and thus it is difficult to ensure the quality of the steel mesh. Utility Model Content

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Example:

[0021] like Figure 1-Figure 3As shown, the utility model provides a side wall reinforcement spacing and verticality control device, including a support rod 1 and a connecting rod 2. The support rod 1 is connected to the enclosure structure 8 that has been completed. The connecting rod 2 is connected to the support rod 1 and can move relative to the support rod 1. There are many ways to connect the support rod 1 and the connecting rod 2. For example, the end of the support rod 1 is tubular and has an internal thread. The connecting rod 2 is provided with an external thread so that the connecting rod 2 can be threadedly connected to the inside of the support rod 1. The connecting rod 2 can be moved relative to the support rod 1 by twisting the connecting rod 2. The connecting rod 2 is also provided with a groove 3 for fixing the steel bar 9. The groove 3 can be composed of two short steel bars 9 welded to the connecting rod 2. The gap between the two welded short steel bars 9 is the groove 3, which can limit and control the steel bar 9.

[0022] When the side wall reinforcement spacing and verticality control device of the utility model is used, the support rod 1 is fixed to the constructed enclosure structure 8. Then, the reinforcement 9 to be adjusted is clamped inside the groove 3 and the connecting rod 2 is moved relative to the support rod 1, so that the reinforcement 9 is pulled to adjust the position. When the reinforcement 9 is adjusted to a suitable position, the connection rod 2 is stopped to fix the position of the reinforcement 9. Then, concrete pouring is performed to ensure the stability of the position of the reinforcement 9, thereby ensuring the quality of pouring. By adjusting the position of the reinforcement 9, the reinforcement can be adjusted to a suitable position, thereby ensuring the spacing and verticality of the side wall reinforcement 9.

[0023] The connecting rod 2 may be provided with a plurality of grooves 3, so that each groove 3 corresponds to a steel bar 9. Figure 1 As shown, the width between the two grooves 3 is fixed, and the distance between the two grooves 3 just corresponds to the spacing requirement of the two steel bars 9 .

[0024] In this embodiment, the support rod 1 and the connecting rod 2 are connected by a connecting piece. Threads are provided at both ends of the connecting piece, and the thread directions at both ends are opposite. The support rod 1 and the connecting rod 2 are each provided with threads at one end that cooperates with the connecting piece. Specifically, the connecting piece can be a section of steel pipe, and the internal threads at both ends of the steel pipe are in opposite directions. When the connecting piece is rotated, the connecting rod 2 moves relative to the support rod 1, while the support rod 1 and the connecting rod 2 may not rotate. As a result, the connecting rod 2 does not need to be rotated during the position adjustment of the steel bar 9, so that the steel bar 9 is always stuck in the groove 3 to ensure stability.

[0025] In this embodiment, the connecting member includes two screw tubes 4 and two connecting rods 5. The two screw tubes 4 are respectively connected to the support rod 1 and the connecting rod 2. The two screw tubes 4 are connected by two connecting rods 5 and the two connecting rods 5 are distributed on both sides of the screw tubes 4. Figure 1As shown, there is a gap between the two connecting rods 5. When rotating the connecting piece, a steel bar 9 is inserted between the two connecting rods 5 and the steel bar 9 is rotated to rotate the connecting piece. In other words, no special tool is required, and the connecting piece can be rotated and adjusted by any rod-shaped tool. This makes the operation more convenient.

[0026] In this embodiment, an expansion bolt is provided at the end of the support rod 1. When the support rod 1 is connected to the enclosure structure 8, a hole is first drilled on the enclosure structure 8. Then, the expansion bolt at the end of the support rod 1 is inserted into the hole and tightened. This makes the connection between the support rod 1 and the enclosure structure 8 easier.

[0027] In this embodiment, two grooves 3 are provided. The end of the connecting rod 2 is also connected to a positioning rod 6, and the connecting rod 2 and the positioning rod 6 are combined to form a U shape. The two grooves 3 are provided at both ends of the positioning rod 6. The spacing between the two grooves 3 is determined by the length of the positioning rod 6.

[0028] In this embodiment, the opening direction of the groove 3 is arranged away from the connecting member. Figure 2 As shown, the openings of the two grooves 3 are both downward. When in use, the connecting rod 2 can simultaneously clamp the two steel bars 9 downward. At the same time, this arrangement makes it difficult for the steel bars 9 to be clamped in when they enter the grooves 3 without being blocked by the connecting rod 2.

[0029] In this embodiment, the support rod 1 is externally threadedly connected with a movable sleeve 7. The movable sleeve 7 is also provided with a groove 3 on its exterior. The position of the movable sleeve 7 can be adjusted by rotating it. When in use, a steel bar 9 is inserted into each of the groove 3 of the connecting rod 2 and the groove 3 of the movable sleeve 7. Since the movable sleeve 7 and the connecting rod 2 are provided separately, the positions of the two relative to the support rod 1 can be adjusted separately, thereby making it more convenient to insert the steel bar 9 and adjust the position of each steel bar 9.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
