[0002] Pile foundation construction in construction projects is often one of the most important parts of building structure construction. The processing quality of cast-in-place pile steel cage is related to the construction quality of bored cast-in-place piles and the safety of the foundation structure of the entire project. Cast-in-place pile steel cage mainly includes longitudinal reinforcement and reinforcing stirrups. The clustered reinforcements are equally spaced around the reinforcing stirrups to form a cylindrical shape. At present, the traditional longitudinal reinforcement spacing control of steel cages generally adopts the method of marking the design dimensions on each reinforcing hoop with a brush. The above method often leads to uneven positioning spacing of the main reinforcement during construction, affecting the welding quality and construction period, and is time-consuming and labor-intensive. The workers' work efficiency is low and there is a waste of labor. Utility Model Content

[0009] The beneficial effects of the technical solution provided by the embodiment of the utility model are as follows: first, according to the longitudinal reinforcement spacing on the design drawing, the actual spacing between two adjacent longitudinal reinforcements is obtained, and then the second positioning member 5 and the protective tube are rotated to the predetermined position, and then the gasket and the first limiting member are rotated until the second positioning member is pressed against the second positioning member. The rotation of the first limiting member can be completed by using the rotating shaft. After adjusting the spacing, the U-shaped mouth of the first positioning member is clamped on the previous longitudinal reinforcement, and then the next longitudinal reinforcement is placed on the second positioning member to achieve the positioning of the longitudinal reinforcement. By setting the first positioning member and the second positioning member, the precise positioning of the longitudinal reinforcement can be achieved, which solves the problem of uneven and inaccurate positioning of the traditional method. The first limiting member adopts a nut with a rotating shaft, and the nut can tighten the second positioning member, and the rotating shaft can tighten the nut without a wrench or other tightening tools, which solves the problem of workers forgetting to bring tightening tools.

[0017] Example 1

[0018] See also Figure 1 to Figure 2 The utility model provides a tool for controlling the spacing of longitudinal bars of a steel cage, comprising a screw rod 1, one end of which is fixedly connected to a first positioning member 2, the other end of which is fixedly connected to a handle 3, the screw rod 1 being threadedly connected to a second positioning member 5, a first limiting member 4, a gasket 8, a protective tube 6, and a second limiting member 7, the protective tube 6 being fixedly connected to one side of the second positioning member 5, one side of the gasket 8 being against the other side of the second positioning member 5, and the first limiting member 4 being against the other side of the gasket 8. The first limiting member is tightened toward the gasket, and the gasket plays a role in protecting the second positioning member.

[0019] Specifically, the first positioning member 2 is in a U-shaped structure, and the three sides of the first positioning member 2 are fixedly connected by plates, and an anti-skid pad 9 is provided on the inner side of the first positioning member 2. The first positioning member is in a U-shaped structure, and the three sides are fixedly connected by plates. The plates in the longitudinal direction of the longitudinal reinforcement are wider, which can prevent the tool from sliding when the longitudinal reinforcement is stuck, and increase the force range, which can not only bear the force but also protect the tool and the longitudinal reinforcement well. The anti-skid pad can be a rubber pad, a plastic pad or other flexible material, and the anti-skid pad can play a good anti-skid role when the tool is used.

[0020] Specifically, the second positioning member 5 has a square structure, and a circular arc is provided at the connection between the second positioning member 5 and the protective tube. The protective tube is a threaded tube. When the second positioning member clamps the longitudinal rib, the protective tube can well protect the thread on the screw rod, so that it is protected from wear by the longitudinal rib during use.

[0021] Specifically, the first limit member 4 is composed of a nut and multiple rotating shafts 401. The rotating shaft 401 is fixedly connected to the side of the nut. The nut can be a common regular hexagonal nut, and the rotating shaft can be a cylinder. Three of them are provided. Their main function is to tighten the second positioning member after tightening to play a role of locking. Moreover, workers usually forget to take a wrench when using it. By providing a rotating shaft, there is no need for fastening tools such as a wrench, which is more convenient and practical, and has a better fastening effect.

[0022] Specifically, the second limiting member 7 is in a square structure, and the second limiting member is provided mainly to prevent the second positioning member from being over-adjusted and causing unnecessary damage.

[0023] Specifically, the handle 3 is a cylindrical rod and is coaxial with the screw rod 1 .

[0024] When the utility model is used, firstly, the actual spacing between two adjacent longitudinal bars is obtained according to the longitudinal bar spacing on the design drawing, then the second positioning member 5 and the protective tube 6 are rotated to the predetermined position, and then the gasket 8 and the first limiting member 4 are rotated until the second positioning member is tightly pressed. The rotation of the first limiting member can be completed by using the rotating shaft 401, and there is no need for tightening tools such as wrenches, which greatly facilitates the use. After adjusting the spacing, the U-shaped opening of the first positioning member is clamped on the previous longitudinal bar, and then the next longitudinal bar is placed on the second positioning member to achieve the positioning of the longitudinal bar.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
