Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a quick connection component for prestressed steel strands. Background Technology

[0002] In the construction industry, prestressed steel strands, with their high strength and high toughness, have become a key material for the construction of bridges, large buildings, and other projects. The quality of their connection directly affects the safety and stability of the engineering structure. The connection of prestressed steel strands is a critical process.

[0003] Existing quick-connect assemblies for prestressed steel strands require that when connecting two steel strands, one strand must be threaded, positioned, and tightened before the other strand can be connected. This process is cumbersome and repetitive, resulting in low overall construction efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing quick-connect components for prestressed steel strands require the threading, positioning, and fastening of one steel strand before connecting the other, resulting in cumbersome and repetitive procedures and low overall construction efficiency. Therefore, this invention proposes a quick-connect component specifically for prestressed steel strands.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-connect assembly for prestressed steel strands, comprising a quick-connect assembly, an adjustment assembly inside the quick-connect assembly, a compression assembly on the quick-connect assembly, a connecting sleeve, fixed anchor rings threaded to both ends of the connecting sleeve, the adjustment assembly comprising a fixed limiting seat and a movable limiting seat, a connecting frame mounted on the top of the movable limiting seat, and an adjustment bolt threaded to the inside of the connecting frame.

[0006] Preferably, the compression assembly includes a spring, one end of which is connected to a spring sheet, and the spring and spring sheet are distributed on the fixed anchor ring.

[0007] Preferably, a rotating seat is installed on the top of the connecting sleeve, and the adjusting bolt is movably connected to the rotating seat.

[0008] Preferably, a steel strand body is movably installed inside the fixed anchor ring, and the steel strand body is movably disposed inside the fixed limit seat and the movable limit seat.

[0009] Preferably, a rotating handle is mounted on the top of the adjusting bolt.

[0010] Preferably, the fixed limiting seat and the movable limiting seat have through grooves inside.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by manually rotating the adjusting bolt, the rotating seat is lowered, causing the movable limiting seat and the fixed limiting seat to clamp the two steel strand bodies simultaneously. This facilitates the connection of the steel strand bodies without the need to install and fix the two steel strand bodies separately, shortening the installation and connection time, achieving rapid connection, and thus improving construction efficiency.

[0013] 2. In this utility model, a spring is installed inside the fixed anchor ring. The elasticity of the spring helps to push the spring piece to press against the outside of the fixed limit seat and the movable limit seat, thereby promoting the fixed limit seat and the movable limit seat to be further stably limited, ensuring improved stability while connecting quickly.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a quick connection assembly for prestressed steel strands, including a quick connection assembly 1, an adjustment assembly 2 inside the quick connection assembly 1, and a compression assembly 3 on the quick connection assembly 1. The quick connection assembly 1 includes a connecting sleeve 101, with fixed anchor rings 102 threaded to both ends of the connecting sleeve 101. The adjustment assembly 2 includes a fixed limiting seat 201 and a movable limiting seat 202. A connecting frame 203 is installed on the top of the movable limiting seat 202, and an adjusting bolt 205 is threaded to the inside of the connecting frame 203. A rotating seat 204 is installed on the top of the connecting sleeve 101, and the adjusting bolt 205 is movably connected to the rotating seat 204. A rotating handle is installed on the top of the adjusting bolt 205.

[0022] In this embodiment, by passing two steel strand bodies 103 through the interiors of two fixed anchor rings 102, and simultaneously causing the steel strand bodies 103 to pass through the interiors of the fixed limiting seat 201 and the movable limiting seat 202, the adjusting bolt 205 is manually rotated to drive the rotating seat 204 to descend, causing the movable limiting seat 202 and the fixed limiting seat 201 to clamp the two steel strand bodies 103 simultaneously. This facilitates the connection of the steel strand bodies 103 without the need to install and fix the two steel strand bodies 103 separately, shortening the installation and connection time, achieving rapid connection, and thus improving construction efficiency. By connecting the outer side of the fixed anchor ring 102 to the internal thread of the connecting sleeve 101, it is beneficial to limit the movement of the fixed limiting seat 201 and the movable limiting seat 202.

[0023] Example 2: As Figures 1-4 As shown, the extrusion assembly 3 includes a spring 301, one end of which is connected to a spring piece 302. The spring 301 and the spring piece 302 are distributed on the fixed anchor ring 102. A steel strand body 103 is movably installed inside the fixed anchor ring 102. The steel strand body 103 is movably disposed inside the fixed limit seat 201 and the movable limit seat 202. Through slots are opened inside the fixed limit seat 201 and the movable limit seat 202.

[0024] In this embodiment, a spring 301 is installed inside the fixed anchor ring 102. The elasticity of the spring 301 helps to push the spring piece 302 to press against the outside of the fixed limit seat 201 and the movable limit seat 202, thereby causing the fixed limit seat 201 and the movable limit seat 202 to be further stably limited, ensuring improved stability while connecting quickly.

[0025] The working principle of this embodiment is as follows: In use, firstly, the two steel strand bodies 103 are respectively inserted into the interiors of the two fixed anchor rings 102, and simultaneously, the steel strand bodies 103 are inserted into the interiors of the fixed limiting seat 201 and the movable limiting seat 202. Then, the adjusting bolt 205 is manually rotated, which causes the rotating seat 204 to descend, causing the movable limiting seat 202 and the fixed limiting seat 201 to clamp the two steel strand bodies 103 simultaneously. This facilitates the connection of the steel strand bodies 103 without the need to install and fix the two steel strand bodies 103 separately, shortening the installation and connection time and achieving rapid connection. Then, the outer side of the fixed anchor ring 102 is connected to the internal thread of the connecting sleeve 101. A spring 301 is installed inside the fixed anchor ring 102. The elasticity of the spring 301 helps to push the spring piece 302 to press against the outer side of the fixed limiting seat 201 and the movable limiting seat 202, thereby further stabilizing the fixed limiting seat 201 and the movable limiting seat 202.
