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

[0032] 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

[0033] like Figure 7-Figure 11 As shown, the front and rear positions in this embodiment are described as follows Fig. 9Taking the top view as an example, with the front at the bottom and the rear at the top, the connection structure 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 slots 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 axially arranged screw hole 111 is opened at the axis 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 to complete the installation; a layer of elastic material layer made of rubber with a thickness of 5 mm 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 that can be briefly pushed open radially and reset and divided into four petals, 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 enter but difficult to exit. 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 below 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.

[0034] More specifically, the insertion mechanism 102 is cylindrical.

[0035] More specifically, the whole body of the through slot 108 is behind the cross beam 107.

[0036] More specifically, the skeleton 106 is in the shape of a "king".

[0037] 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.

[0038] More specifically, the diameter of the front end face of the frustum 105 is larger than the diameter of the rear end face, and the difference is between 1 mm - 10 mm.

[0039] 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.

[0040] More specifically, a plurality of notches are evenly distributed on the periphery of the limiting plate to facilitate gripping. Example 2

[0041] The front and rear positions in this embodiment are described as follows: Figure 6 Taking the side view as an example, with the left side being the front and the right side being the rear, the quick-install prefabricated panel 1 of the present invention comprises: a prefabricated panel 112, a connecting structure, and a functional panel 113; the prefabricated panel 112 is formed by pouring concrete and wraps the skeleton 106 described in Example 1 inside; an X-shaped groove 114 is provided on the front end face of the functional panel 113, a through hole 115 is provided at the intersection of the X-shaped groove 114, and a sleeve 116 extending rearward is provided on the rear side of the through hole 115; during installation, the sleeve 116 is sleeved on the outside of the plug-in mechanism, the cross beam is embedded in the X-shaped groove 114, the plug-in block is inserted into the plug-in mechanism, and the screw is screwed into the screw hole at the rear end of the plug-in block, until the limiting plate abuts against the plug-in mechanism and the rear end of the sleeve 116 to complete the installation. In order to achieve that the limiting plate abuts against the plug-in mechanism and the rear end of the sleeve 116 at the same time, it is obvious that the lengths of the front and rear end faces of the functional panel 113 (including the sleeve 116) are equal to the lengths of the front and rear end faces of the mounting frame (including the plug-in mechanism).

[0042] More specifically, the front portion of the functional plate 113 is made of a sound-absorbing material, and the rear portion and the sleeve 116 are integrally cast from an alloy material. Example 3

[0043] After assembling the quick-install prefabricated panels 2*2 described in Example 2, they are fixed in the wall frame structure 2 using the mounting holes. The wall frame structure 2 can be a steel structure or a concrete structure.

[0044] The quick-install prefabricated panels designed in the present invention can be installed in a building with a steel structure or a concrete structure individually or in combination. After the frame is installed, it is only necessary to insert the insertion mechanism and the prefabricated panels thereon into the insertion mechanism at the center of the installation frame from the front side, and insert the functional panel from the rear side of the insertion mechanism. The frustum of the insertion mechanism will be stuck in the hollow of the insertion mechanism and cannot be pulled out. After the insertion mechanism is fully inserted, the locking mechanism is screwed in and abuts against the rear ends of the insertion mechanism and the functional panel to complete the installation. The present invention has low cost, light weight, and is quick and easy to install.

[0045] 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.
