Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a building steel bar bending device to solve the existing one. When bending the roof steel bar, the traditional way of bending the steel bar is that the worker bends it with his feet. This method is not only inefficient, but also for For workers with poor health, it consumes more physical strength, which is not conducive to improving construction efficiency; on the other hand, most of the existing devices can only be used on the ground and cannot bend the steel bars bound and fixed on the roof, and the use environment is affected. limit problem

Embodiment 1

[0037] as attached figure 1 to attach Figure 8 Shown:

[0038] The invention provides a building steel bar bending device, which includes a clamping base 1; seven rollers 2 are evenly spaced and rotated on the clamping base 1; refer to figure 1 , the clamping base 1 includes a rectangular groove A101 and a rectangular notch 102, a rectangular groove A101 is opened at the left end of the clamping base 1, and seven rotating connecting seats are welded in the rectangular groove A101, and each rotating connecting seat is rotatably connected with A roller 2; refer to eg Figure 6 , two backing plates 3 are slidably connected to the bottom surface of the clamping base 1, and the backing plates 3 are not limited to two pieces, so during use, the backing plates 3 can be appropriately added according to the bending position required for use; the roller 2 There are two guide limit rods 5 that are rotatably connected to the rotating shaft, and a clamping block 4 is slidably connected...

Embodiment 2

[0041] On the basis of embodiment 1, refer to as Figure 7 , also includes that the clamping base 1 and the clamping block 4 are both trapezoidal columnar structures, so it is convenient to insert steel bars between the clamping base 1 and the clamping block 4 during use, which improves the convenience of use to a certain extent ; referenced as Figure 8 , there are two limit rods 11 threaded on the clamping block 4, so during use, the limit of the bending angle can be realized by adjusting the limit rods 11 through the thread, so as to realize fast bending at a fixed angle; refer to figure 1 , Two fixing clips 12 are welded on the top surface of the clamping block 4, so the handle 10 can be disassembled and fixed with the fixing clips 12 after use, which can reduce the space occupied by the device when placed.

Abstract

The invention provides a building steel bar bending device, relates to the field of building construction instruments, and solves the problems that the bending efficiency is low due to the fact that currently bending is carried out through adopting a method of bending with feet and the use limitation is high due to the fact that existing bending equipment is inconvenient to use on a roof. The building steel bar bending device comprises a clamping base, wherein the clamping base is rotatably connected with seven rolling shafts, two guide limiting rods are rotationally connected to the rolling shafts, and four elastic telescopic rods are further rotatably connected to the rolling shafts. According to the building steel bar bending device, through cooperative arrangement of the clamping base,a clamping block, the guide limiting rods, a cylindrical shaft and a cam, a steel bar is clamped by pressing and driving the clamping block through the cam and at the same time a handle is continuously pressed, so that the guide limiting rods and the elastic telescopic rods are rotatably connected with the rolling shafts, the handle is pressed to realize in linkage that the clamping block, with the rolling shaft rotating shaft as the axis, rotates to realize the bending motion, and therefore the linkage effect of clamping and bending is achieved, and the structure of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of building construction equipment, and more specifically relates to a building steel bar bending device. Background technique [0002] In construction projects, it is necessary to pour cement on the roof. In this step, steel bars need to be laid to assist the tensile strength of the concrete slab and reduce plastic deformation. However, in order to ensure that the steel bars can be fully laid, too long is often reserved. For steel bars, before the final cement pouring, it is necessary to bend this part of the excess steel bars before cement pouring. [0003] For example, the application number: CN201611252424.2, the invention discloses a steel bar bending machine, comprising: a material seat, which is installed on the frame, and a groove is formed on the material seat; it is arranged in the groove for The conveying wheel unit for transporting steel bars; the fixed block arranged in the groove and located o...
