DETAILED DESCRIPTION

[0024] The utility model is described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1~Figure 5As shown, a prefabricated wall including an insulation layer includes a main wall 15, an insulation layer 16 and a finishing layer 17 which are sequentially connected to the main wall through insulation wall connectors. The main wall 15 is a reinforced concrete wall. The insulation layer 16 is a foamed polystyrene board or a phenolic foam board. The finishing layer is concrete.

[0026] The insulation wall connector includes a fixed seat, a positioning rod 1 inserted on the fixed seat, and a tightening seat 2 arranged at the tail end of the positioning rod 1; the fixed seat includes a fixed disk 3 and a nail-piercing tube 4 vertically arranged at the center of the fixed disk 3, and the nail-piercing tube 4 has a truncated cone-shaped tail end 5, which is easy to insert into the insulation board. The side wall of the truncated cone-shaped tail end 5 is provided with a telescopic long groove 6 along the generatrix, and the positioning rod 1 passes through the nail-piercing tube 4 and passes out from the truncated cone-shaped tail end 5. When the positioning rod passes through the truncated cone-shaped tail end, the pore of the telescopic long groove becomes larger, and the tail end of the nail-piercing tube can strengthen the connection strength with the insulation board 15 after expansion; the outer wall of the truncated cone-shaped tail end 5 is circumferentially provided with a strip pattern 9, and when the tail end of the nail-piercing tube expands, the strip pattern further increases the friction between the nail-piercing tube and the insulation board. The positioning rod 1 is threaded steel, and the fixed seat and the tightening seat 2 are both made of polyvinyl chloride.

[0027] The fixing plate 3 and the tightening seat 2 are respectively arranged on both sides of the insulation layer 16, and the staples are inserted into the insulation layer 16. The tail end of the positioning rod 1 is fixedly connected to the steel bar 18 in the main wall 15, and the head end of the positioning rod 1 is fixedly connected to the hanging net 19, and the hanging net 19 is located in the finishing layer 17.

[0028] The head end of the positioning rod 1 is provided with an annular groove 7, which is used to clamp the hanging net outside the insulation layer. The top of the annular groove 7 of the positioning rod 1 is provided with a tangential groove 10. The annular groove and the tangential groove can fix the hanging net from two directions perpendicular to each other, and are suitable for fixing the cross-fixing points of the horizontal wires and the longitudinal wires of the hanging net.

[0029] The fixing plate 3 is provided with a staple parallel to the nail barrel 4. The staple comprises a cylindrical nail column 11, a barb 12 provided on the side wall of the nail column 11, and a conical tip 13 provided at the tail end of the nail column 11. The staple is inserted into the insulation layer together with the nail barrel, and the barb on the staple is stuck in the insulation board, so that the fixing plate cannot be removed.

[0030] The positioning rod 1 is provided with an external thread 8, and the tightening seat 2 is inserted into the positioning rod 1 and matched with the external thread 8. The fixing plate and the tightening seat clamp the insulation board from both sides of the insulation board, and the connecting piece is completely fixed on the insulation board.

[0031] The fixing plate 3 is provided with a pouring hole 14. During pouring, the pouring hole can increase the contact area with the concrete and improve the overall strength.

[0032] When the prefabricated wall is manufactured, the fixing seat fixes the connector on the insulation board, the fixing plate is on the outside of the insulation board, the conical tail end of the nail tube and the nail are inserted into the insulation board, the positioning rod passes through the nail tube and penetrates the insulation board, and the tightening seat tightens the insulation board from the tail end of the positioning rod to complete the installation of the connector and the insulation board. Several connectors are evenly distributed and installed on the insulation board, and the top of the positioning rod is clamped with a hanging net to form a combination of the insulation board and the wire mesh. The combination is placed on the outside of the steel bars 18 of the main wall, the tail end of the positioning rod is fixed to the steel bars of the main wall, the positions of the various components of the insulation wall are fixed, and templates are added at both ends and concrete 17 is poured to complete the construction of the entire prefabricated wall.
