Description

TECHNICAL FIELD

[0001] The application relates to the technical field of building construction auxiliary equipment, and in particular to a reinforcing mesh fixing support. BACKGROUND

[0002] In the field of building construction, reinforcing mesh is widely used, which plays an important role in reinforcing the structural strength and stability of a concrete structure, however, fixing and positioning of the reinforcing mesh has been a problem to be solved in the construction process of the reinforcing mesh.

[0003] In view of the above related technologies, the inventor believes that the reinforcing mesh fixing method in the prior art usually uses a simple support structure or a temporary fixing method through binding, and these methods have many disadvantages, on the one hand, the simple support structure cannot accurately adjust the height and position of the reinforcing mesh, and has poor adaptability to reinforcing meshes of different specifications, and cannot meet the requirements of different construction scenes, on the other hand, the binding method is not only complicated and inefficient, but also prone to loosening during the construction process, and cannot guarantee the stability of the reinforcing mesh, which may cause the reinforcing mesh to be displaced or deformed in the subsequent concrete pouring process, thereby affecting the quality and safety of the entire concrete structure, therefore, in order to solve the above problems, the application provides a reinforcing mesh fixing support. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the problems in the background art, the application provides a reinforcing mesh fixing support.

[0005] The reinforcing mesh fixing support provided by the application comprises a U-shaped base and a lifting platform, a bidirectional screw rod is rotatably connected between two flanges of the U-shaped base, two sliding blocks are symmetrically connected to the outside of the bidirectional screw rod, a transmission plate is hingedly connected to the top of each of the two sliding blocks, and the ends of the two transmission plates away from the sliding blocks are hingedly connected to the bottom of the lifting platform; a plurality of fixing seats are fixedly connected to the surface of the lifting platform at equal intervals, a circular groove is formed in the inside of each fixing seat, a screw rod is threadedly connected to the upper surface of each fixing seat, and an arc-shaped clamping plate is rotatably connected to the bottom end of the screw rod extending into the circular groove.

[0006] Preferably, protrusions are fixedly installed on the two sides of the arc-shaped clamping plate, a first limiting rod is slidably connected to the inside of each protrusion, and the two ends of the first limiting rod are fixedly connected to the inner wall of the circular groove.

[0007] Preferably, connecting ears are installed on the two sides of the lifting platform, a second limiting rod is fixedly connected to the inside of each connecting ear, and the bottom ends of the two second limiting rods are fixedly connected to the flange ends of the U-shaped base.

[0008] Preferably, one end of the bidirectional screw rod extends to the outside of the U-shaped base and is fixedly connected with a rotating handle.

[0009] Preferably, two corners of the bottom of the base are provided with foot brake universal wheels, and the two corners of the bottom of the U-shaped base away from the foot brake universal wheels are provided with directional wheels.

[0010] In summary, the present application has the following beneficial technical effects:

[0011] 1. In the present application, the lifting function of the lifting platform is realized through the structural design of the bidirectional screw rod, the sliding block threadedly connected with the bidirectional screw rod, and the transmission plate. Rotating the bidirectional screw rod can make the symmetrical sliding blocks move towards or away from each other, thereby driving the transmission plate to move, and finally making the lifting platform lift stably. This design can conveniently adjust the height of the steel mesh, so that it can adapt to the fixing needs of different construction scenes and steel meshes of different thicknesses, and ensure the accuracy of construction.

[0012] 2. The cooperation of the circular groove, the screw rod, and the arc-shaped clamping plate on the fixing seat provides a reliable way for the fixation of the steel bars. By placing the steel bars in the circular groove and rotating the screw rod, the arc-shaped clamping plate can be driven to clamp the steel bars, thereby firmly fixing the steel bars in the fixing seat, improving the firmness of the steel mesh fixation, effectively preventing the displacement and deformation of the steel mesh during construction, and ensuring the stability of the structure during subsequent concrete pouring.
