Description

Technical Field

[0001] The present application relates to the technical field of construction equipment, and more specifically, to a construction steel bar positioning mechanism. Background Art

[0002] Construction engineering refers to the various technical works and completed engineering entities such as planning, surveying, design, construction, and completion for the construction, renovation, or expansion of buildings and ancillary structures and facilities, as well as the installation of supporting lines, pipelines, and equipment. It also refers to the construction of various houses and buildings, also known as construction workload. This part of the investment must start construction and materials, and can only be realized through construction activities. Steel bars are the most widely used material in the construction industry. The casting of load-bearing beams or load-bearing columns is usually used in conjunction with steel frames. Steel frames are mostly composed of multiple groups of steel bars, and the walls of the multiple groups of steel bars are bundled and folded into rectangular thin steel bars. Workers mostly prepare the steel frames on the ground at the construction site. Some steel bars and thin steel bars are in contact with the ground, making it extremely inconvenient to manually insert the wire, which indirectly reduces the efficiency of steel frame production.

[0003] The document with prior art publication number CN 218522280 U provides a steel bar positioning mechanism for construction. The device can adjust the distance between the parts through two sets of movable arms, and is suitable for making steel bar racks of various sizes. At the same time, the force-bearing bars support the steel bars so that they are in a suspended state, which is conducive to manual insertion and winding of steel wire, and can efficiently bundle the steel bar racks. When the steel bar racks are bundled, the force-bearing bars automatically retract while being lifted vertically upward to prevent the steel bar racks from being restricted when being lifted.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the device can only position the square steel frame, and cannot be used to position the cylindrical steel cage, which leads to the problem of low practicality.

[0005] In view of this, we propose a construction steel bar positioning mechanism. Utility Model Content

[0006] 1. Technical problems to be solved

Second, after the binding is completed, the two sets of support frames can be slid apart to facilitate the separation of the steel cage and the support frame. The auxiliary support mechanism can be raised and lowered to provide auxiliary support for steel cages with different outer diameters to improve the overall support stability. Finally, the steel cage can be annularly welded by rotating the mounting frame.

[0011] As an optional solution to the technical solution of this application document, the support frame includes a slide and a double-threaded screw rotatably connected to the base, the base is provided with a sliding groove adapted to the slide, the double-threaded screw is threadedly connected to the slide, and the mounting frame also includes a shaft fixed coaxially with the ring and rotatably connected to the upper end of the slide.

A hand-cranked wheel is fixedly installed at one end of the double-threaded screw to facilitate the rotation of the double-threaded screw, and when the double-threaded screw rotates clockwise, the two slides slide relative to each other, and when it rotates counterclockwise, the two slides slide away from each other, and the rotation of the shaft is connected to the upper end of the slide.

[0013] As an optional solution to the technical solution of this application document, the fixing part includes a U-shaped clamp adapted to the circular ring and a sleeve fixed to the U-shaped clamp and coaxially arranged with the shaft rod, a second locking screw is threadedly connected to the sleeve, and the U-shaped clamp is threadedly connected to a first locking screw that is against the circular ring.

[0014] By adopting the above technical solution, the U-shaped clamp is clamped and fixed with the corresponding circular ring, and the steel cage with different outer diameters is adjusted. The U-shaped clamp can be fixed on the circular ring by the first locking screw being against the circular ring. Then the steel bar is inserted into the casing, and the steel bar can be fixed in the casing by the second locking screw being against the steel bar.

[0015] As an optional solution to the technical solution of this application document, a mounting hole is provided on the side of the U-shaped clamp away from the sleeve, an L-plate is slidably inserted into the mounting hole, and the L-plate is rotatably connected to the first locking screw.

[0016] By adopting the above technical solution, the horizontal plate of the L-plate is rotatably connected to the first locking screw through a bearing. Therefore, when the first locking screw moves downward, the L-plate moves downward along the mounting hole and is stuck on one side of the ring to improve the fixing strength between the U-shaped clamp and the ring.

[0032] Reference Figure 1-Figure 7 In this embodiment, three groups of circular rings 301 are provided, and after being sequentially sleeved, they are fixedly connected to each other through fixing rods. Multiple fixing parts 4 can be disassembled and assembled on circular rings 301 of different outer diameters to facilitate the positioning and use of steel cages with different outer diameters. At the same time, the two groups of support frames 2 are adjusted relative to or apart from each other. First, it is convenient to adjust the use of steel cages of different lengths. Second, after the binding is completed, the two groups of support frames 2 are slid apart to facilitate the separation of the steel cage and the support frame 2. The lifting of the auxiliary support mechanism 5 can provide auxiliary support for steel cages of different outer diameters to improve the overall support stability. Finally, the steel cage can be annularly welded by rotating the mounting frame 3.

[0033] The support frame 2 includes a slide 201 and a double-threaded screw 202 rotatably connected to the base 1. The base 1 is provided with a slide groove 101 adapted to the slide 201.

The mounting frame 3 also includes a shaft 302 fixed coaxially with the ring 301 and rotatably connected to the upper end of the slide 201.

[0034] Reference Figure 2 and Figure 3 and Figure 5The slide 201 is adapted to slide in the slide groove 101, and the two ends of the double-threaded screw rod 202 are rotatably connected to the base 1 through bearings, and the double-threaded screw rod 202 is a screw rod with two sections of threads in opposite directions. One end of the double-threaded screw rod 202 is fixedly installed with a hand-cranked wheel to facilitate the rotation of the double-threaded screw rod 202, and when the double-threaded screw rod 202 rotates clockwise, the two slides 201 slide relative to each other, and when it rotates counterclockwise, the two slides 201 slide away from each other, and the rotation of the shaft rod 302 is connected to the upper end of the slide 201.

[0035] The fixing member 4 includes a U-shaped clamp 401 adapted to the ring 301 and a sleeve 402 fixed to the U-shaped clamp 401 and coaxially arranged with the shaft 302.

[0038] Reference Figure 6 and Figure 7 The horizontal plate of the L-plate 403 is rotatably connected to the first locking screw 4011 through a bearing. Therefore, when the first locking screw 4011 moves downward, the L-plate 403 moves downward along the mounting hole 4012 and is stuck on one side of the ring 301 to improve the fixing strength of the U-shaped clip 401 and the ring 301.
