Description

TECHNICAL FIELD

[0001] The utility model relates to a reinforcing steel bar bending moment device belongs to construction auxiliary tool technical field. BACKGROUND

[0002] After the prefabricated laminated slab hoisting is completed, the beam body needs to be placed under the beam body position between the laminated slab. In order to avoid the mustache muscle of the laminated slab to hinder the beam body, the mustache muscle needs to be bent to the vertical state through the tool, and after the beam body is placed, the mustache muscle is bent to the horizontal state through the tool.

[0003] In the prior art construction (Chinese patent publication No. CN110499857B), two small steel blocks are fixed on the elbow of the steel bar to clamp and bend the mustache muscle, but the steel block can only clamp the straight line segment of the mustache muscle, and the straight line segment of the mustache muscle clamped by the steel block will concentrate stress when the mustache muscle is bent to the horizontal state, which is prone to secondary bending problem. UTILITY MODEL CONTENTS

[0004] In order to solve the above technical problems, the utility model provides a reinforcing steel bar bending moment device.

[0005] The utility model is realized through the following technical schemes.

[0006] The utility model provides a reinforcing steel bar bending moment device, which comprises a cylinder body, a vertical accommodating groove is arranged in the cylinder body, and the vertical accommodating groove can completely accommodate the straight line segment of the mustache muscle.

[0007] It also includes a handle fixed on the upper cylinder body for stress.

[0008] The handle is welded at the middle part of the outer side of the cylinder body, and the cylinder body is symmetrical to the handle; the handle is perpendicular to the cylinder body.

[0009] The handle is made of threaded steel bar; the cylinder body is made of steel pipe.

[0010] The cylinder body at the back of the vertical accommodating groove is provided with a clamping groove, and the clamping groove is distributed at the upper and lower positions of the cylinder body with the handle as the symmetrical point. The clamping groove is connected with the end face space of the cylinder body.

[0011] The utility model has the advantages that the straight line segment of the mustache muscle is completely accommodated in the accommodating groove of the cylinder body for bending; the situation that only the straight line segment of the mustache muscle is clamped and the bending concentrates stress is avoided; and the problem of easy secondary bending is solved.

[0016] The technical scheme of the utility model is described further below, but the scope of protection is not limited to the description.

[0017] As Figs. 1 to 3 described.

[0018] The steel bar bending moment device of the application comprises:

[0019] The cylinder 1 has a vertical accommodating groove 11 inside, and the cylinder 1 is made of a steel pipe. The vertical accommodating groove 11 can completely accommodate the straight section 31 of the mustache muscle 3 in the bent state, and the mustache muscle 3 is in a horizontal state on the laminated board 4 in the normal state, and can also be bent to a vertical state by the steel bar bending moment device of the application.

[0020] The cylinder 1 is fixed with a grip handle 2 for bearing stress, the grip handle 2 is welded at the middle part of the outer side of the cylinder 1, the cylinder 1 is symmetrical to the grip handle 2, and the grip handle 2 is perpendicular to the cylinder 1. The grip handle 2 is made of a threaded steel bar.

[0021] The cylinder 1 is provided with a clamping groove 12 at the back of the vertical accommodating groove 11, and the clamping groove 12 is distributed at the upper and lower positions of the cylinder 1 with the grip handle 2 as the symmetrical point. The clamping groove 12 is connected to the end face space of the cylinder 1, so that the clamping groove 12 can clamp the local bent part of the mustache muscle 3 for pulling.

[0022] In use, the accommodating groove 11 of the cylinder 1 completely accommodates the straight section 31 of the mustache muscle 3, a torque is generated by using the grip handle 2 as a force arm to bend the mustache muscle 3 to the horizontal state, and the bent section 32 of the mustache muscle 3 is not completely bent, so that the clamping groove 12 clamps the local bent part of the mustache muscle 3 for secondary pulling correction.

[0023] Since the straight section 31 of the mustache muscle 3 is completely accommodated in the accommodating groove 11 of the cylinder 1 for bending, the situation that only the straight section of the mustache muscle is clamped and the bending force is concentrated is avoided, and the problem of easy secondary bending is solved.
