Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to an adjustable soft cable connector for prefabricated floor slabs. Background Technology

[0002] With the advancement of industrialized construction, precast floor slabs have been widely used in building engineering due to their advantages such as high construction efficiency and controllable quality. In the installation and connection of precast floor slabs, flexible cable connectors are key components for hoisting and force transfer. However, existing flexible cable connectors for precast floor slabs have the following shortcomings: Insufficient adjustability: Most soft cable connectors are either not adjustable in length or have complicated adjustment operations, making it difficult to adapt to the installation height and spacing requirements of different precast floor slabs, resulting in poor construction flexibility.

[0003] Poor stability: The load-dispersing ability of the connection structure is weak, and the force is mostly applied at a single point or a few points, which can easily lead to local stress concentration and affect the reliability of the precast floor slab connection.

[0004] Installation and positioning difficulties: The upper and lower connecting parts lack a precise positioning structure, making alignment difficult during installation, time-consuming and labor-intensive, and reducing construction efficiency.

[0005] Inconvenient to disassemble and assemble: Some connectors are one-piece or have complex connection methods, making the disassembly and assembly process cumbersome and not conducive to on-site construction and later maintenance.

[0006] The aforementioned problems result in low construction efficiency and unreliable connections for precast floor slabs, hindering the further promotion of precast building technology. Therefore, there is an urgent need to develop an adjustable, stable, and easy-to-install flexible cable connector to meet the requirements for efficient and reliable connections of precast floor slabs. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an adjustable soft cable connector for precast floor slabs, which solves the technical problems of poor length adjustability, insufficient connection stability, difficult installation and positioning, and inconvenient assembly and disassembly of existing soft cable connectors for precast floor slabs.

[0008] To achieve the above objectives, this utility model provides the following technical solution: An adjustable flexible cable connector for precast floor slabs includes a flexible cable, a cross-shaped support arm, an upper connecting seat, and a lower connecting seat; The support arm is detachably connected to the upper connecting seat; The flexible cable passes through the center of the upper connecting seat; The upper connecting seat has a connecting hole at the bottom, the lower connecting seat has an opening at the top that mates with the connecting hole, and the lower connecting seat has a positioning post at the top and the upper connecting seat has a positioning hole at the bottom that mates with the positioning post. The lower connector is also provided with a central hole at the top, through which the soft cable passes.

[0009] Preferably, the upper connecting seat has a mounting hole at its top, and the support arm is connected to the mounting hole by a connecting pin, the connecting pin including a pin rod.

[0010] Preferably, the support arm is a cross-shaped four-arm structure, with the four arms evenly distributed around the circumference of the upper connecting seat, and the opening of the lower connecting seat is a rectangular groove structure that is adapted to the connecting part at the bottom of the upper connecting seat.

[0011] Preferably, there are at least three positioning posts, which are evenly distributed around the central hole, and the number of positioning holes is consistent with the number of positioning posts and corresponds one-to-one.

[0012] Preferably, the upper connecting seat has multiple connecting holes distributed circumferentially along the bottom of the upper connecting seat, which are used to connect with the opening structure of the lower connecting seat through fasteners.

[0013] Preferably, the flexible cable is provided with a threaded adjustment section for adjusting the length of the flexible cable, and the connecting pin has three pins, which are adapted to the number and position of the mounting holes.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The length is flexibly adjustable: the soft cable is equipped with a threaded adjustment section, which can quickly adjust the length according to the installation height and spacing requirements of the precast floor slabs, making it highly adaptable and greatly improving construction flexibility.

[0015] Significantly improved connection stability: The cross-shaped support arms are used, with four arms evenly distributed around the upper connector. This allows for connection to multiple stress points on the precast floor slab, effectively dispersing the load, avoiding local stress concentration, and ensuring the long-term stability of the connection structure.

[0016] Precise and efficient installation and positioning: The positioning holes of the upper connector and the positioning posts of the lower connector are precisely matched, and the bottom of the upper connector and the opening of the lower connector are adapted to each other, realizing quick alignment during installation and significantly improving construction efficiency.

[0017] Easy to assemble and disassemble: The components are connected by detachable means (such as connecting pins and fasteners), making the installation and disassembly process simple and quick, reducing construction difficulty, and facilitating on-site operation and later maintenance.

[0018] High structural reliability: Through the positioning and matching of the positioning column and the positioning hole, the fastener connection of the connecting hole, and the load distribution effect of the cross-shaped support arm, the structural strength and connection reliability of the entire connector are effectively guaranteed, ensuring the safety of the precast floor slab connection.
