[0001] The utility model relates to the technical field of steel bar welded mesh, in particular to a steel bar welded mesh sheet with high compressive strength and crack resistance. Background Technique

[0002] A steel bar welded mesh is a mesh-shaped steel bar product welded and formed in a factory, consisting of longitudinal steel bars and transverse steel bars arranged at a certain interval and at right angles, and all intersection points are welded together. The steel bar welded mesh is widely used in various building structures. For example, in the construction process of railway box girders, the steel bar welded mesh is widely used. The use of the steel bar welded mesh significantly improves the quality of the bridge deck pavement, improves the flatness of the bridge deck, and can effectively increase the crack resistance of the bridge deck.

[0003] In some building constructions, higher strength requirements are imposed on the steel bar welded mesh. Currently, cold-rolled ribbed steel bars are mainly used to make the steel bar welded mesh. However, the strength of the cold-rolled ribbed steel bars is only improved compared with ordinary steel bars. At the joints of the steel bar welded mesh made of cold-rolled ribbed steel bars, connection is usually achieved by welding, so that during long-term use of the steel bar mesh sheet, the joints are prone to cracking.

[0004] In view of this, it is necessary to provide a steel bar welded mesh sheet with high compressive strength and crack resistance. Content of the Utility Model

[0005] The purpose of the utility model is to provide a steel bar welded mesh sheet with high compressive strength and crack resistance, so as to solve the problem of insufficient strength of the steel bar welded mesh.

[0024] According to Figures 1-6, this embodiment provides a steel bar welded mesh with high compressive strength and crack resistance, including a first fixing plate 1, a second fixing plate 2, longitudinal steel bars 5, and transverse steel bars 6. The longitudinal steel bars 5 are fixedly connected to the transverse steel bars 6. A first through groove 10 is provided on the lower end surface of the first fixing plate 1, and a second through groove 20 is provided on the upper end surface of the second fixing plate 2. The first through groove 10 and the second through groove 20 are arranged perpendicular to each other. The first fixing plate 1 and the second fixing plate 2 are installed at the connection of the longitudinal steel bars 5 and the transverse steel bars 6. The connection of the longitudinal steel bars 5 and the transverse steel bars 6 is usually connected by welding. By installing the first fixing plate 1 and the second fixing plate 2 at the connection, the compressive strength and crack resistance of the connection are enhanced. A plurality of grooves 12 are provided on the sides of the first fixing plate 1 and the second fixing plate 2. A plurality of clamping components 3 are provided on the first fixing plate 1 and the second fixing plate 2. The clamping component 3 includes an extension rod 31, and the extension rod 31 is slidably connected to the groove 12. Two groups of clamping components 4 are provided on both the first fixing plate 1 and the second fixing plate 2. The clamping component 4 includes two symmetrically arranged clamping structures 41. The clamping structure 41 includes a sleeve 411, a first threaded rod 410 is threadedly connected to the sleeve 411, a sleeve shaft 412 is rotatably connected to the first threaded rod 410, the sleeve shaft 412 is slidably connected to the sleeve 411, and a clamping arc plate 413 is fixedly installed on the sleeve shaft 412. Through the two groups of symmetric clamping structures 41 provided on the first fixing plate 1, by moving the clamping structure 41 to a suitable position, the first threaded rod 410 threadedly connected to the sleeve 411 is used to move the sleeve shaft 412, thereby driving the movement of the clamping arc plate 413 to fixedly connect the longitudinal steel bar 5 below the first fixing plate 1. The two groups of symmetric clamping structures 41 provided on the second fixing plate 2 fixedly connect the transverse steel bar 6 above the second fixing plate 2. By the way of mutual fixation up and down, the stability of the connection of the steel bars is improved.

[0025] A plurality of clamping members 11 are fixedly installed on the lower end surface of the first fixing plate 1, and a plurality of clamping grooves 21 are fixedly installed on the upper end surface of the second fixing plate 2. The clamping members 11 and the clamping grooves 21 are correspondingly arranged. By clamping and connecting the first fixing plate 1 and the second fixing plate 2, the connection of the longitudinal steel bars 5 and the transverse steel bars 6 is protected between the first fixing plate 1 and the second fixing plate 2, thereby enhancing the compressive strength of the steel bar mesh.

[0026] The clamping component 3 further includes a ratchet rack 32, a second spring 33, a slider 34, and a rib plate 35. The ratchet rack 32 is fixedly installed in the groove 12. The other end of the extension rod 31 is fixedly connected to one end of the second spring 33. The other end of the second spring 33 is fixedly connected to the slider 34. The slider 34 is slidably connected to the extension rod 31. The slider 34 is fixedly connected to the rib plate 35. The rib plate 35 is clamped and connected to the ratchet rack 32. Through the clamping connection between the rib plate 35 and the ratchet rack 32, it is used to move and clamp the arc plate 413, so that after the clamping arc plate 413 clamps the steel bar, it will always maintain the clamping state of the steel bar.

[0027] A second threaded hole 4121 is provided on the lower end surface of the sleeve shaft 412. A second threaded rod 4131 is fixedly installed on the outer arc surface of the clamping arc plate 413. The clamping arc plate 413 is threadedly connected to the sleeve shaft 412. If the clamping arc plate 413 does not match the diameter of the steel bar to be clamped, the clamping arc plate 413 can be replaced to achieve the effect of matching the diameter of the steel bar.

[0028] A first threaded hole 4111 is provided on the sleeve 411. The first threaded rod 410 passes through the sleeve 411 and is threadedly connected to the sleeve 411. By rotating the first threaded rod 410, the sleeve shaft 412 drives the clamping arc plate 413 to move.

[0029] Two symmetrically arranged first limit blocks 22 and a second limit block 23 are fixedly installed in the card slot 21. The second limit block 23 is cooperatively arranged with the two first limit blocks 22. The card member 11 is limited by the two first limit blocks 22 and the second limit block 23 to prevent the card member 11 from shaking in the card slot 21, thereby ensuring stable connection.

[0030] The specific operation is as follows: Place the first fixing plate 1 and the second fixing plate 2 at the welded joint of the longitudinal steel bar 5 and the transverse steel bar 6. Pass the cross-welded transverse steel bar 6 and longitudinal steel bar 5 through the first through groove 10 and the second through groove 20 respectively. Squeeze the first fixing plate 1 and the second fixing plate 2 so that the card member 11 is stuck in the card slot 21. Move the sleeve 411 on the clamping structure 41 to a suitable position by pushing the first extension rod 31. Rotate the first threaded rod 410, and then push the sleeve shaft 412 to bring the clamping arc plate 413 into clamping contact with the steel bar. Check whether the clamping arc plate 413 fits the steel bar to be clamped. If it fits, operate other clamping structures 41 synchronously. If it does not fit, rotate the first threaded rod 410 in the reverse direction to drive the clamping arc plate 413 away from the steel bar. Rotate the clamping arc plate 413 to replace the clamping arc plate 413, and at the same time replace the clamping arc plates 413 on other clamping structures 41 to reinforce the steel bar mesh with insufficient welding strength.
