Description

Portable construction line traction reinforcement device

technical field

The invention relates to the technical field of construction engineering, and more specifically relates to a portable construction line traction reinforcement device.

Background technique

In building construction, threading operations are often required, that is, various lines or steel bars (ie, construction lines) used in construction are threaded in pipelines, and external equipment such as winches and beam threading machines are often used in construction. One end of various wires or steel bars to be threaded needs to be clamped so that the various wires or steel bars are firmly connected with external equipment, so as to maintain sufficient external force for traction during the entire threading process. Once a large number of construction lines or steel bars are threaded at one time, there will be relative sliding between each construction line or steel bars. The simple fastening structure can easily lead to poor connection and inconvenience to threading, such as broken lines. , Slipping, power inconvenience and other problems.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a portable construction line traction reinforcement device, which aims to conveniently and quickly bundle the construction lines, and can be conveniently connected and penetrated.

Technical purpose of the present invention is achieved through the following technical solutions:

A portable construction line traction reinforcement device, including a pull ring, a cylinder body and a tightening part, wherein:

One end of the cylinder body is closed and a pull ring is fixed at the central position, the other end of the cylinder body is open and a central clamping column is fixed coaxially in the center, and a second thread is provided outside the cylinder wall; one end of the cylinder body is closed A tightening part is arranged on the outer side of the barrel wall, and a first thread is arranged on the inner side of the tightening part, and the first thread and the second thread are matched;

From the closed end of the cylinder to the open end of the cylinder, the inner surface of the cylinder wall forms a cylindrical inner cavity with equal diameter, and the thickness of the cylinder wall gradually increases, and on the cylinder wall at the open end of the cylinder, along the circumferential direction of the cylinder wall Make notches evenly.

In the above technical solution, the number of the notches is 3 or 4.

In the above technical solution, the apex angle of the notch is 10-15 degrees.

In the above technical solution, the tightening part is a hexagonal nut.

Compared with the prior art, the technical solution of the present invention adopts the outside clamping method of the sleeve, uses the tightening parts to tighten along the cylinder wall, and gradually reduces the space between the cylinder wall and the central clamping column, so as to realize the inner clamping of the sleeve. The fixing of the construction line means that by tightening the tightening parts, the extruded cylinder wall shrinks inwardly. Since the cylinder wall at the opening end of the cylinder is provided with a gap, the extruded cylinder wall will shrink radially inward, clamping Tighten the construction line set between the barrel wall and the central clamping column to secure the connection. In actual use, the connection can be realized conveniently and reliably only by tightening the tightening parts, which improves the construction efficiency and facilitates threading.

detailed description

The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

The three drawings as shown in accompanying drawings 1-3 are the cross-sectional view, side view and front view of the present invention respectively. The portable construction line traction reinforcement device of the present invention includes a pull ring, a cylinder and a tightening part, wherein:

One end of the cylinder body is closed and a pull ring is fixed at the central position, the other end of the cylinder body is open and a central clamping column is fixed coaxially in the center, and a second thread is provided outside the cylinder wall; one end of the cylinder body is closed A tightening part is arranged on the outer side of the barrel wall, and a first thread is arranged on the inner side of the tightening part, and the first thread and the second thread are matched;

From the closed end of the cylinder to the open end of the cylinder, the inner surface of the cylinder wall forms a cylindrical inner cavity with equal diameter, and the thickness of the cylinder wall gradually increases, and on the cylinder wall at the open end of the cylinder, along the circumferential direction of the cylinder wall Make notches evenly.

In the above technical solution, the number of the notches is 3 or 4, and four are shown in the figure.

In the above technical solution, the apex angle of the notch is 10-15 degrees.

In the above technical solution, the tightening part is a hexagonal nut.

Compared with the prior art, the technical solution of the present invention adopts the outside clamping method of the sleeve, uses the tightening parts to tighten along the cylinder wall, and gradually reduces the space between the cylinder wall and the central clamping column, so as to realize the inner clamping of the sleeve. The fixing of the construction line means that by tightening the tightening parts, the extruded cylinder wall shrinks inwardly. Since the cylinder wall at the opening end of the cylinder is provided with a gap, the extruded cylinder wall will shrink radially inward, clamping Tighten the construction line set between the barrel wall and the central clamping column to secure the connection. In actual use, the connection can be realized conveniently and reliably only by tightening the tightening parts, which improves the construction efficiency and facilitates threading.

The present invention has been described as an example above, and it should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacements that can be made by those skilled in the art without creative labor all fall within the scope of this invention. protection scope of the invention.
