[0001] The present invention relates to the field of prefabricated building material processing, and particularly to a quick-installation connection structure for prefabricated slabs. Background Art

[0002] Currently, prefabricated building projects are a type of building project with fast installation, simple and efficient construction. Among them, the coordinated construction of prefabricated exterior wall panels and prefabricated walls is extremely widespread in the application of wall construction. In actual construction, operators first fixedly install the prefabricated wall at the designated construction site, and then attach and fix the prefabricated exterior wall panel to the outer side wall of the prefabricated wall to complete the installation.

[0003] In the prior art, such as a connection structure and connection method for a prefabricated exterior wall panel and a prefabricated wall proposed in Application No. CN202110401108.1, adopting this technical solution, operators can efficiently and quickly fix the prefabricated panel to the outer side wall of the positioning wall, and can effectively ensure the connection strength of the prefabricated panel fixed to the outer side wall of the positioning wall and the position stability after long-term use. However, in this solution, the structure is relatively complex and the number of components is large, resulting in higher costs and self-weights. Summary of the Invention

[0004] In order to provide a quick-installation solution for prefabricated slabs with low cost and low self-weight, the present invention proposes a quick-installation connection structure for prefabricated slabs, and its structure includes: an installation frame, an insertion mechanism, and a locking mechanism; a cross beam is provided on the diagonal of the installation frame, and a number of installation holes are provided on the outer periphery. An insertion mechanism is provided at the intersection of the cross beams. The rear side of the insertion mechanism is divided into several petals by a number of evenly distributed radial through slots. The front side of the inner wall of the insertion mechanism is a cylindrical surface, and there are several axially stacked frustum-shaped hollowings at the rear side; the insertion mechanism includes: an insertion block, the front part of the insertion block is a cylinder, the rear part is several axially stacked frustums, a skeleton is fixed at the front end of the insertion block, and an axial screw hole is opened at the center of the rear end. The locking mechanism includes a limiting plate and a screw rod at its center. During installation, the insertion block is inserted into the insertion mechanism, and the screw rod is screwed into the screw hole at the rear end of the insertion block until the limiting plate abuts against the rear end of the insertion mechanism to complete the installation; the insertion mechanism is made of an elastic material or an elastic material layer is provided on the inner wall of the insertion mechanism.

[0005] Preferably, the insertion mechanism is cylindrical.

[0006] Preferably, the entire through slot is located behind the cross beam.

[0007] Preferably, the skeleton is in the shape of a "king" character or a "day" character.

[0008] Preferably, there are four frustum-shaped hollowings on the inner side of the insertion mechanism, and there are also four frustums on the insertion block, and they match the shape and size of the hollowings.

[0009] Preferably, the diameter of the front end surface of the cone is larger than the diameter of the rear end surface, and the difference is between 1 mm and 10 mm.

[0010] Preferably, the insertion mechanism is integrally formed.

[0011] Preferably, a plurality of notches are evenly distributed on the periphery of the limiting plate to facilitate gripping.

[0012] The quick-install connection structure designed in the present invention can be installed in a building with a steel structure or a concrete structure in a single or multiple combinations. After the frame is installed, it is only necessary to insert the insertion mechanism into the plug-in mechanism at the center of the installation frame. The round table of the insertion mechanism will be stuck in the hollow of the plug-in mechanism and cannot be pulled out. After it is fully inserted, the locking mechanism is screwed in and abuts against the rear end of the plug-in mechanism to complete the installation. The present invention has low cost, light weight, and is quick and easy to install. BRIEF DESCRIPTION OF THE DRAWINGS

Some or all of the units may be selected according to actual needs to achieve the purpose of the solution of this embodiment.

[0025] In addition, each functional unit in each embodiment of the present invention may be integrated into one processing unit, or each unit may exist physically separately, or two or more units may be integrated into one unit. Example 1

[0026] like Figure 1-Figure 5 As shown, the front and rear positions in this embodiment are described as follows Figure 3Taking the top view as an example, with the front at the bottom and the back at the top, the quick-installation connection structure of the precast slab of the present invention includes: an installation frame 101, an insertion mechanism, and a locking mechanism 109; a cross beam 107 is provided diagonally on the installation frame 101, and a number of installation holes 103 are provided on the outer periphery. The installation holes 103 are used for connecting between installation frames or connecting the installation frame to the main structure. An insertion mechanism 102 is provided at the intersection of the cross beam 107. The rear side of the insertion mechanism 102 is divided into four petals by four evenly distributed radial through grooves 108. The front side of the inner wall of the insertion mechanism 102 is a cylindrical surface, and there are several axially stacked frustum-shaped hollowings 110 at the rear side; the insertion mechanism includes: an insertion block. The front part of the insertion block is a cylinder 104, and the rear part is several axially stacked frustums 105. A skeleton 106 is also fixed at the front end of the insertion block. The skeleton 106 is used to support the precast slab. An axial screw hole 111 is opened at the center of the rear end. The locking mechanism 109 includes a limiting plate and a screw at its center. During installation, the insertion block is inserted into the insertion mechanism 102, and the screw is screwed into the screw hole 111 at the rear end of the insertion block until the limiting plate abuts against the rear end of the insertion mechanism 102, then the installation is completed; a 5-mm-thick elastic material layer made of rubber is provided on the inner wall of the insertion mechanism 102. When the insertion mechanism is inserted into the insertion mechanism 102, through the elastic deformation of the elastic material layer and the rear side of the insertion mechanism 102 divided into four petals that can be briefly pushed open radially and reset, the frustum 105 of the insertion mechanism is inserted into each hollowing 110 and then limited and prevented from returning. Its structure design is similar to that of a cable tie which is easy to insert but difficult to take out. In this example, the insertion mechanism 102 is made of steel material or aluminum alloy material, and the wall thickness of the insertion mechanism 102 is less than 10 mm. Due to its relatively thin wall thickness, the rear side divided into four petals can be briefly pushed open and reset by the frustum 105 of the insertion mechanism, and then fixed by the locking mechanism 109 to further prevent the insertion mechanism from coming out; in actual production and processing, the length of the cylinder 104 is 10-20 mm larger than the thickness of the installation frame 101 for the installation of the skeleton 106.

[0027] More specifically, the insertion mechanism 102 is cylindrical.

[0028] More specifically, the whole body of the through groove 108 is behind the cross beam 107.

[0029] More specifically, the skeleton 106 is in the shape of a "king".

[0030] More specifically, there are four frustum-shaped hollowings 110 on the inner side of the insertion mechanism 102, and there are also four frustums 105 of the insertion block, and they match the shape and size of the hollowings 110.

[0031] More specifically, the diameter of the front end face of the frustum 105 is larger than that of the rear end face, and the difference is between 1 mm and 10 mm.

[0032] More specifically, the insertion mechanism is integrally formed, and specifically can be formed by investment casting of metal or alloy materials. If it is used in temporary buildings with general strength requirements, such as temporary board houses, the insertion mechanism can also be formed by injection molding of engineering plastics.

[0033] More specifically, a plurality of notches are evenly distributed on the periphery of the limiting plate to facilitate gripping.

[0034] The quick-install connection structure designed in the present invention can be installed in a building with a steel structure or a concrete structure in a single or multiple combinations. After the frame structure is installed, the insertion mechanism only needs to be inserted into the plug-in mechanism at the center of the installation frame. The round table of the insertion mechanism will be stuck in the hollow of the plug-in mechanism and cannot be pulled out. After it is fully inserted, the locking mechanism is screwed in and abuts against the rear end of the plug-in mechanism to complete the installation. The present invention has low cost, light weight, and is quick and easy to install.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
