[0002] Concrete refers to the general term for engineering composite materials in which aggregate is cemented into a whole by cementitious materials. Usually, the term concrete refers to cement concrete, also known as ordinary concrete, which is made of cement as the cementitious material, sand and stone as the aggregate, and water (which may contain additives and admixtures) in a certain proportion and is obtained by mixing. It is widely used in civil engineering.

[0003] In the process of implementing the present application, the inventor found that there are at least the following problems in this technology: Since concrete is prone to cracking itself, it is necessary to moisturize its concrete walls during the construction process. In the prior art, although there are devices to replace manual water spraying for moisturizing, when spraying, the spray nozzles generally face the wall directly, and the water flow impacts the wall, which is likely to cause water splash and waste of water resources. The contact time between the water flow and the wall is short, and the moisturizing effect on the concrete wall is not good. Content of the Utility Model

[0004] The purpose of the utility model is to provide a concrete crack control component for straight thread connection of high-strength steel bars to solve the problems raised in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A concrete crack control component for straight thread connection of high-strength steel bars includes two symmetrically arranged moving supports.

[0009] Preferably, the thread paths at both ends of the threaded rod member respectively penetrate through the two L-shaped moving plates, such that the top surfaces of the two L-shaped moving plates are in sliding friction contact with the bottom surface of the adjustable slide plate member.

[0010] Preferably, a servo motor is installed on the outer wall of one of the vertical plates, and the output shaft of the servo motor is connected to the threaded rod member.

[0011] Preferably, a water tank is installed on the top surface of one of the moving supports, a hose is connected to the top surface of the water tank through a water pump, and the output end of the hose is hermetically connected to two spray pipes through a shunt pipe.

Specific implementation mode

[0021] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0022] Unless otherwise defined, the up, down, left, right, front, back, inner and outer directions involved in this article are based on the up, down, left, right, front, back, inner and outer directions in the figures shown in the present utility model, and are hereby explained together.

[0023] This embodiment discloses a concrete crack control member for high-strength steel bar straight thread connection as Figures 1 to 3 shown, which includes two symmetrically arranged movable supports 1. Universal wheels 2 are symmetrically installed on the bottom surfaces of the two movable supports 1. Under the action of the universal wheels 2 and the movable supports 1, the device can be moved to the required position. A water tank 4 is installed on the top surface of one of the movable supports 1. The top surface of the water tank 4 is connected to a hose 6 through a water pump 5. The output end of the hose 6 is hermetically connected to two spray pipes 11 through a shunt pipe 7.

[0024] Two inverted U-shaped support members 3 are symmetrically installed on the top surfaces of the two movable supports 1. Two auxiliary support plates 9 are symmetrically welded between the tops of the two U-shaped support members 3. The two auxiliary support plates 9 can assist in supporting the two U-shaped support members 3, thereby playing a role in support and protection.

[0025] A slidable adjustable slide member 8 is connected between the upper parts of two U-shaped support members 3. One auxiliary support plate 9 is connected to the adjustable slide member 8 through an electric push-pull rod 10. Rectangular through grooves 18 are formed in the inner walls of the upper parts of the two U-shaped support members 3. The two ends of the adjustable slide member 8 are respectively inserted into the two rectangular through grooves 18. When the electric push-pull rod 10 pushes or pulls the adjustable slide member 8, the adjustable slide member 8 slides and rubs in the two rectangular through grooves 18.

[0026] The electric push-pull rod 10 can push the adjustable slide member 8 to slide in the two rectangular through grooves 18, so as to adjust the position of the adjustable slide member 8. At the same time, it can adjust the positions of the L-shaped moving plate 13 and the spray pipe 11, so as to meet the use at different positions, thereby reducing the number of times of moving the equipment and improving the use efficiency.

[0027] On the bottom surface of the adjustable slide member 8, two L-shaped moving plates 13 arranged in opposite directions slide relative to each other. Spray pipes 11 are arranged at the free ends of the two L-shaped moving plates 13. A plurality of spray nozzles 12 are arranged obliquely downward on the opposite sides of the two spray pipes 11. One of the spray pipes 11 is close to the wall. The water output from the spray nozzles 12 flows down the wall along the trend. The flowing water can wet the wall when flowing down the wall, and at the same time can prevent the water from splashing directly, reducing the waste of water resources and improving the moisturizing effect of the wall.

[0028] On the bottom surface of the adjustable slide member 8 located between the two U-shaped support members 3, vertical plates 14 are symmetrically welded. A threaded rod member 15 with thread paths in opposite directions is rotatably installed between the two vertical plates 14. The thread paths at both ends of the threaded rod member 15 respectively penetrate through the two L-shaped moving plates 13, so that the top surfaces of the two L-shaped moving plates 13 are in sliding friction contact with the bottom surface of the adjustable slide member 8. A servo motor 17 is installed on the outer wall of one of the vertical plates 14. The output shaft of the servo motor 17 is connected to the threaded rod member 15. Limiting disks 16 are welded on the circumferential side of the threaded rod member 15 between the two thread paths.

[0029] The servo motor 17 drives the threaded rod member 15 to rotate. Under the action of the two thread paths, the two L-shaped moving plates 13 can be driven to move towards or away from each other, so as to synchronously adjust the positions of the two spray pipes 11, so that the spray pipe 11 in any direction can be close to the wall to be wetted, so as to meet the wetting use of walls in different positions and improve the use efficiency.

[0030] On the outer wall of the lower part of the U-shaped support member 3 beside the water tank 4, there is a PLC for controlling the opening and closing of the servo motor 17, the water pump 5 and the electric push-pull rod 10. The PLC model can be selected according to actual needs. In the present utility model, the PLC model is S7-200, which has the advantages of high reliability, strong anti-interference ability and convenient maintenance.

[0031] Working principle

[0032] For the concrete crack control component with straight thread connection of high-strength steel bars, the electric push-pull rod 10 can push the adjustable sliding plate 8 to slide in the two rectangular through grooves 18, so as to adjust the position of the adjustable sliding plate 8. At the same time, the positions of the L-shaped movable shelf plate 13 and the spray pipe 11 can be adjusted. The servo motor 17 drives the threaded rod member 15 to rotate. Under the action of the two thread paths, the two L-shaped movable shelf plates 13 can move towards or away from the center, so as to synchronously adjust the positions of the two spray pipes 11, so that the spray pipe 11 in any direction can closely adhere to the wall to be wetted.
