[0002] With the rapid development of urban construction, high-quality land has gradually become a scarce resource. Designers continue to explore the potential of underground space, and large and deep basements such as underground garages, underground shopping malls, underground stations and other underground structures have appeared in large numbers. Nowadays, there are many buildings in housing construction projects, and the area occupied is very large. The area of ​​a single basement can reach tens of thousands of square meters or even hundreds of thousands of square meters. At present, the practice of the basement is to leave a post-cast strip to eliminate the harmful cracks that may be caused by the uneven shrinkage or settlement of the reinforced concrete structure. It has not changed its essence. The anti-cracking problem of the structure has become increasingly prominent, and cracking of the bottom plate and water leakage are common. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a pre-buried connector that enhances the connection performance of the expansion reinforcement belt, so as to improve the connection strength of the concrete on both sides of the expansion reinforcement belt.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an embedded connector with enhanced connection performance of expansion reinforcement belt, comprising dense mesh arranged in pairs, a plurality of support components are arranged between the pairs of dense mesh, the support components include a sleeve, and clamping parts installed in pairs on both sides of the sleeve, the clamping parts on both sides are driven by the sleeve to move in directions away from each other, and the ends of the clamping parts are provided with bayonet sockets that abut against the dense mesh.

[0005] As a further improvement of the present invention, threaded holes are respectively provided at both ends of the sleeve corresponding to the mounting clips, the rotation directions of the threaded holes on both sides are arranged in opposite directions, and the clips mounted on both sides of the sleeve are respectively connected and cooperated with the corresponding threaded holes.

[0006] As a further improvement of the present invention, the end of the bayonet for abutting against the dense-hole steel wire is provided with at least one inclined guide surface.

[0014] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0015] Reference Figure 1-3 As shown, a pre-embedded connector for enhancing the connection performance of the expansion reinforcement belt comprises a dense mesh 1 arranged in pairs, and a plurality of groups of support components are arranged between the dense mesh 1 in pairs. The support components are arranged between the dense mesh 1 and support the steel wires on both sides in the horizontal direction. The number of support components can be adjusted according to the actual expansion coefficient of concrete to improve the overall support strength and reduce the deformation phenomenon. The support components comprise a sleeve 2 and clamping members 3 installed in pairs on both sides of the sleeve 2. The clamping members 3 on both sides are driven by the sleeve 2 to move in directions away from each other. The ends of the clamping members 3 are provided with bayonet ports 4 abutting against the dense mesh 1. The bayonet ports 4 abut against the dense mesh 1 and are locked on the steel wire by adjusting the sleeve 2. The sleeve 2 is provided with threaded holes at both ends corresponding to the installation of the clamping members 3. The rotation directions of the threaded holes on both sides are arranged in opposite directions. The clamping parts 3 are respectively threadedly connected with the corresponding threaded holes. When in use, the clamping parts 3 are abutted against the steel wire by the clamping mouth 4 of the clamping part 3, and the clamping parts 3 on both sides are driven to apply pre-tightening force by rotating the sleeve 2 to improve the overall compressive strength. The clamping mouth 4 is used to abut against the end of the dense-pore steel wire and at least one inclined guide surface 5 is provided. In this embodiment, a pair of guide surfaces 5 are provided, and the guide surfaces 5 can further help the support assembly to be centered, and help construction personnel to quickly install the support assembly. The outer surface of the clamping part 3 is provided with a plurality of recesses 6 and protrusions 7. This arrangement can further improve the connection strength of concrete on both sides. Both sides of the dense-pore steel wire mesh 1 are provided with anchor rods 8 for winding support thereof. The anchor rods 8 are provided with hooks 9 for clamping the dense-pore steel wire mesh 1. The dense-pore steel wire mesh 1 is wound on the anchor rods 8 to facilitate tightening the dense-pore steel wire mesh 1. The hooks 9 provided on the anchor rods 8 further tension the dense-pore steel wire mesh 1 to prevent it from loosening.
