[0002] Steel mesh is also called welded steel mesh, steel welded mesh, steel welded mesh, steel welded mesh, steel mesh, etc. It is a mesh in which the longitudinal steel bars and transverse steel bars are arranged at a certain interval and at right angles to each other, and all intersections are welded together. This new type of reinforcement is particularly suitable for large-scale concrete projects and can improve the overall construction speed and efficiency.

[0003] The existing double-layer steel mesh needs to be provided with tie bars, and the suspension of the tie bars should ensure that the tie bars are tightly connected to the upper and lower rows of main bars. Generally, hooks are provided on both sides of the tie bars. However, when the lower steel mesh is close to the ground, the tie bars cannot be normally suspended on the lower row of main bars due to the lack of sufficient moving space. Therefore, in the prior art, the bottom end of the tie bars is usually set at a right angle (such as Figure 1 Although the existing tie-reinforcement form can solve the installation problem of tie-reinforcement, when the tie-reinforcement is subjected to lateral force, the tie-reinforcement is prone to tilt and even detach from the lower row of main reinforcements, affecting the rigidity of the steel mesh.

[0021] In order to more clearly illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the present invention. For those of ordinary skill in the art, without creative efforts, other embodiments obtained based on this drawing and embodiment all fall within the protection scope of the present invention.

[0022] According to Figures 1-6 As shown, a bending device for the tie bars of a double-layer steel bar mesh includes a base 1. A top plate 2 is fixedly installed above the base 1. A slide table 3 is movably installed on the top plate 2. A lifting frame 5 is liftably installed on the slide table 3. A jacking assembly 4 is fixedly installed on the slide table 3. The jacking assembly 4 is used to drive the lifting frame 5 to move on the slide table 3. The jacking assembly 4 can be a hydraulic jack, a hydraulic rod, a cylinder, and an electric telescopic rod. Preferably, the jacking assembly 4 uses a hydraulic jack. The bottom end of the lifting frame 5 can move to the lower part of the base 1. A tie rod 7 is fixedly installed at the bottom end of the lifting frame 5.

[0023] In this embodiment, columns 8 are fixedly installed at the four end points of the base 1. The top plate 2 is fixedly installed at the top ends of the columns 8. Relief grooves 9 are provided at the centers of the base 1 and the top plate 2. The lifting frame 5 is located inside the relief grooves 9. Slide blocks 10 are fixedly installed at the left and right ends of the bottom of the slide table 3. The slide blocks 10 are slidably installed on a guide rail 11. The guide rail 11 is fixedly installed on the top plate 2. A screw rod 12 is rotatably installed at the bottom of the top plate 2 through a bearing seat. A screw nut 13 is in threaded cooperation with the screw rod 12. The screw nut 13 is fixedly installed at the bottom of the slide table 3. A handwheel 14 is fixedly installed at the front end of the screw rod 12. The construction worker rotates the screw rod 12 through the handwheel 14. Under the cooperation of the screw rod 12 and the screw nut 13, the slide table 3 slides along the guide rail 11, thereby adjusting the front and rear positions of the lifting frame 5.

[0024] In this embodiment, a limit rod 15 is fixedly installed at the bottom rear end of the lifting frame 5. The length of the limit rod 15 is the same as the width of the lifting frame 5. When the lifting frame 5 moves towards the tie bar, the limit rod 15 will abut against the tie bar. At this time, the tie rod 7 is aligned with the right-angle section of the tie bar, thus facilitating the construction worker to quickly and accurately adjust the position of the tie rod 7.

[0025] In this embodiment, the lifting frame 5 is integrally of a C-shaped structure. A reinforcing rib 6 is welded at the bent portion of the lifting frame 5. Two sets of connecting seats 19 matching the lifting frame 5 are provided on the top plate 2. The lifting frame 5 is slidably installed on the connecting seats 19. A locking bolt 20 is installed on the side wall of the lifting frame 5 through threaded fit. The locking bolt 20 penetrates through the side wall of the lifting frame 5. By tightening the locking bolt 20, the locking bolt 20 abuts against the end face of the side rod of the lifting frame 5, so as to limit the movement of the lifting frame 5 on the sliding table 3 through the locking bolt 20.

[0026] In this embodiment, a first through groove 16 is formed at one end of the base 1 close to the limiting rod 15. A limiting plate 17 is inserted into the first through groove 16. When positioning the lifting frame 5, the limiting plate 17 is inserted into the first through groove 16, and the limiting plate 17 abuts against the side part of the tension bar, preventing the tension bar from moving on the upper row of main reinforcement bars under the action of the limiting rod 15. A second through groove 18 is formed on the top plate 2, and the size of the second through groove 18 is the same as that of the first through groove 16. During the handling process, the limiting plate 17 is taken out of the first through groove 16 and placed in the second through groove 18.

[0027] When the present utility model is in use, the construction worker places the base 1 on the upper layer of the steel bar mesh and moves the base 1 above the tension bar. Then, the lifting frame 5 is moved downward until the bottom end of the lifting frame 5 contacts the ground. Then, the limiting plate 17 is inserted into the first through groove 16 on the base 1, and the limiting plate 17 abuts against the side part of the tension bar. Then, the construction worker rotates the screw rod 12 through the hand wheel 14. Under the cooperation of the screw rod 12 and the screw nut 13, the sliding table 3 drives the lifting frame 5 to approach the tension bar. When the limiting rod 15 abuts against the tension bar, the pull rod 7 moves below the right-angle section of the tension bar. At this time, the construction worker jacks up the lifting frame 5 through the jacking assembly 4, and the right-angle section of the tension bar is bent upward under the action of the pull rod 7, so that the bottom end of the tension bar hooks on the lower row of main reinforcement bars, preventing the tension bar from detaching from the lower row of main reinforcement bars, and thus improving the stiffness of the steel bar mesh.

[0028] The above embodiments are only exemplary embodiments of the present utility model and are not used to limit the present utility model. The protection scope of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present utility model within the essence and protection scope of the present utility model, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present utility model.
