Description

Technical Field

[0001] This utility model belongs to the field of steel reinforcement application technology, specifically relating to a device for manufacturing steel mesh for tunnels. Background Technology

[0002] Highway tunnel construction typically employs composite lining structures. In the initial construction phase, a large area of ​​steel mesh needs to be installed on the support layer, necessitating the use of steel mesh fabrication equipment.

[0003] Currently, application number 202021713590X discloses a steel mesh fabrication device suitable for any size, including a rectangular frame. Each side of the rectangular frame is provided with a number of steel bar placement and positioning devices, wherein the number and position of the steel bar placement and positioning devices on each side correspond to each other. The steel bar placement and positioning devices are detachably connected to the side of the rectangular frame, or are slidably connected along the side of the rectangular frame.

[0004] Although existing fabrication equipment can produce steel mesh, in practice, the need to clamp the steel bars into the slots results in slow placement and removal of the steel bars. Furthermore, different slots are required for different steel bar diameters, which reduces flexibility. Utility Model Content

[0005] The purpose of this invention is to provide a device for making steel mesh for tunnels that is suitable for steel bars of different diameters and can quickly install and disassemble steel bars.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for fabricating steel mesh for tunnels, comprising:

[0008] The connecting frame is perpendicular to the horizontal plane;

[0009] Crossbeams are spaced apart on the connecting frame, with their direction aligned with the vertical direction of the connecting frame, and the axis of the crossbeams is parallel to the horizontal direction of the connecting frame.

[0010] Fixed rails are provided on at least two sets of the crossbeams, perpendicular to the crossbeams, for fixing the vertical reinforcing bars;

[0011] Reinforcing bar support rods are provided perpendicular to the beams on at least two sets of the aforementioned beams to support the transverse reinforcing bars;

[0012] Support legs are used to support the connecting frame.

[0013] Furthermore, an L-shaped steel plate is provided at the top of the support leg for leveling the vertical and horizontal reinforcing bars.

[0014] Furthermore, the support leg includes: a support rod, a connecting rod, and an inclined support rod. The support rods are in two sets, with two rods in each set respectively located at the bottom of the steel plate. The support rods in each set are connected to each other by a connecting rod. The inclined support rod is connected to the connecting frame.

[0015] Furthermore, a second reinforcing rib is provided on the diagonal line of the side of the steel plate away from the connecting frame.

[0016] Furthermore, the connecting frame is a rectangular frame, with a first reinforcing rib provided on the diagonal of the rectangular frame.

[0017] Furthermore, a round steel support is fixed to the outer wall of the fixed track.

[0018] Furthermore, one end of the reinforcing angle steel is connected to the outer wall of the steel bar support rod, and the other end of the reinforcing angle steel is connected to the crossbeam.

[0019] Furthermore, the steel plates are fixed to the support legs and connecting frame respectively by welding.

[0020] Furthermore, the first and second reinforcing ribs are fixed to the connecting frame and the steel plate respectively by welding.

[0021] Furthermore, the support rod is rotatably mounted at the bottom of the steel plate, the inclined support rod and the connecting frame are rotatably connected, and the connecting rod is a telescopic rod.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This invention manufactures a steel mesh by setting crossbeams on a connecting frame and fixing rails and steel support rods vertically mounted on the crossbeams. Specifically, firstly, crossbeams are spaced along the vertical direction of the connecting frame. Then, fixing rails and steel support rods are vertically mounted on the crossbeams. Finally, the entire assembly is supported by support legs. When manufacturing, vertical steel bars are first placed in each fixing rail, and then horizontal steel bars are placed on the steel support rods, forming a mesh-like cross structure. The above operation is repeated until the required engineering conditions are met. Finally, the mesh is welded together. This structure solves the problem of slow steel bar placement and removal caused by the previous slot method. Furthermore, because this structure does not require consideration of the steel bar diameter, it improves the flexibility and applicability of the device. Attached Figure Description

[0029] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0030] like Figures 1-4 In this embodiment, it includes: a connecting frame 10, a crossbeam 3, a fixed track 1, a steel support rod 2, and a support leg 7;

[0031] Among them, the connecting frame 10 is a square frame, which is arranged perpendicular to the horizontal plane and is set on the top of the supporting leg 7;

[0032] Along the vertical direction of the connecting frame 10, the crossbeams 3 are arranged at intervals on the connecting frame 10, and the axis of the crossbeams 3 is parallel to the horizontal direction of the connecting frame 10.

[0033] It should be noted that there are 6 crossbeams 3. Among them, the crossbeams 3 near the two ends of the connecting frame 10 are vertically equipped with fixed rails 1, and the fixed rails 1 between each group of crossbeams 3 are in corresponding positions. The remaining 4 crossbeams 3 are vertically equipped with steel support rods 2, and the steel support rods 2 between each group of crossbeams 3 are in corresponding positions. At the same time, the fixed rails 1 and steel support rods 2 are arranged in a cross pattern.

[0034] Specifically, the vertical reinforcing bars are placed on the fixed track 1, at which point the vertical reinforcing bars are parallel to each other. Then, the horizontal reinforcing bars are placed on the reinforcing bar support rod 2, at which point the horizontal and vertical reinforcing bars form a mesh structure. The above operation is repeated until the requirements of the project are met.

[0035] In this embodiment, an L-shaped steel plate 6 is provided on the top of the support leg 7;

[0036] It should be noted that the frame 10 is fixedly connected along one side of the L-shaped steel plate 6, and the L-shaped steel plate 6 is fixedly connected to the horizontal plane and the support leg 7.

[0037] Specifically, the steel plate 6, which is parallel to the horizontal plane, is responsible for bearing the vertical reinforcing bars and keeping the ends of each vertical reinforcing bar at the same height when they contact the steel plate 6. The steel plate 6, which is perpendicular to the horizontal plane, is responsible for keeping the ends of each horizontal reinforcing bar at the same level when they contact the steel plate 6.

[0038] In this embodiment, the support leg 7 includes: support rod 700, connecting rod 710 and inclined support rod 720. The support rod 700 is in two groups, with two rods in each group and rotatably disposed on the bottom edge of the steel plate 6. Each group is connected to the other through the connecting rod 710.

[0039] It should be noted that the rotating support rod 700 can be rotated to adjust the overall tilt angle and height, and the connecting rod 710 is a telescopic rod;

[0040] Specifically, when the two sets of support rods 700 tilt outward, the overall height decreases. At this time, it is necessary to adjust the length of the connecting rod 710 to make it longer and to reinforce the support rods 700.

[0041] It should be noted that the inclined support rod 720 and the connecting frame 10 are rotatably connected;

[0042] Specifically, after adjusting the support rod 700, in order to keep the whole structure stable, the diagonal support rod 720 needs to be adjusted accordingly to stabilize the whole structure.

[0043] In summary, by designing the support leg 7 as an adjustable structure, it can be flexibly adjusted according to the welder's own welding habits, greatly improving the comfort of the welder.

[0044] In this embodiment, a second reinforcing rib 9 is provided on the diagonal line of the side of the steel plate 6 away from the connecting frame 10.

[0045] In this embodiment, the connecting frame 10 is a rectangular frame, and a first reinforcing rib 8 is provided on the diagonal of the rectangular frame.

[0046] In this embodiment, a round steel support 4 is fixed on the outer wall of the fixed track 1 to enhance the support capacity of the fixed track 1.

[0047] In this embodiment, the outer wall of the steel bar support rod 2 is connected to one end of the reinforcing angle steel 5, and the other end of the reinforcing angle steel 5 is connected to the crossbeam 3;

[0048] It should be noted that there are two reinforcing angle steels 5, each set on the symmetrical sides of the reinforcing bar support rod 2, and each reinforcing angle steel 5 and the crossbeam 3 form a triangle with the reinforcing bar support rod 2.

[0049] In this embodiment, the steel plate 6 is fixed to the support leg 7 and the connecting frame 10 by welding.

[0050] In this embodiment, the first reinforcing rib 8 and the second reinforcing rib 9 are fixed to the connecting frame 10 and the steel plate 6 respectively by welding.

[0051] Working principle:

[0052] First, adjust the angle and height of the support leg 7 according to personal habits, control the entire device and make it stationary, then start to place the first layer of vertical steel bars along the fixed track 1. Next, place the first layer of horizontal steel bars on the steel bar support rod 2, and then repeat the process of placing the vertical and horizontal steel bars. When the specified construction requirements are met, perform welding operations on the whole device. After the welding is completed and the acceptance standards are met, remove the whole device from the device. The steel mesh is now complete.
