[0030] like Figure 1 As shown, the wallboard connecting fastener provided in this embodiment includes an inner anchor 5 and an outer anchor 6. The inner anchor 5 is L-shaped and consists of a lower horizontal plate 53 and an upper vertical plate 51. The two opposite sides of the lower horizontal plate 53 are bent downward to form a facing card 54 for matching with the back of the facing panel. A horizontal strip opening 52 is provided at the upper end of the upper vertical plate 51. The outer anchor 6 is plate-shaped or column-shaped, and both upper and lower ends are horizontally bent to the same side to form an upper connecting portion 62 and a lower connecting portion 61. The upper connecting portion 62 is used to buckle with a steel frame or steel cage in the wallboard structural layer, and the lower connecting portion 63 passes through the strip opening 52 of the inner anchor 5 and connects with the inner anchor 5. The lower end of the inner anchor 5 is connected to the facing layer 4 of the wallboard through the facing card 54, and the upper end is connected to the outer anchor through the horizontally bent lower connecting portion and the strip opening. The installation method is simple and convenient, and the overall structure is simple.

[0031] In specific implementation, the outer anchor 6 can also be horizontally bent to the left and right sides at the upper and lower ends, and the bent parts at the upper and lower ends form the upper connecting part and the lower connecting part respectively. Of course, in specific implementation, the upper connecting part 62 and the lower connecting part 61 can also be arranged in the middle and fixed by welding.

[0032] In addition, the external anchor 6 can also be designed to be in a T-shape, consisting of an upper connecting portion, a lower connecting portion, and a vertical plate located between the upper connecting portion and the lower connecting portion.

[0033] Specifically, the width of the strip opening 52 is greater than the width of the outer anchor 6. This arrangement allows the lower connecting portion at the lower end of the outer anchor to be inserted into the strip opening and move laterally in the strip opening to adjust the position when the outer anchor is connected to the inner anchor, even if there is a certain position offset between the two components, and the connection is more flexible.

[0034] In addition, in order to ensure the overall strength of the fastener, the inner anchor 5 and the outer anchor 6 are made of metal or plastic. In the specific production, if plastic is used, it is necessary to ensure that the strength and hardness of the plastic are high enough. When metal is used, in addition to welding, it can also be cast.

[0035] When the facing card plate 54 is clamped and fixed with the facing layer, in order to prevent the inner anchor from loosening after fixing and ensure the fixing effect of the inner anchor 5, the two facing card plates 54 of the inner anchor in this embodiment are bent obliquely toward the middle to form an inverted "eight" shape. In this way, when the facing card plate is clamped and fixed with the facing layer, the whole is inward buckled and will not loosen. Of course, in the specific implementation, the two facing card plates 54 can also be bent outward to form an outward "eight" shape.

[0036] The inner anchor 5 in this embodiment is formed by bending a whole plate multiple times, has high strength and low manufacturing cost. Specifically, the lower horizontal plate 53 and the upper vertical plate 51 have the same width and can be bent from a single plate, or can be welded or cast.

[0037] like Figure 2-Figure 4 As shown, the present embodiment further provides a prefabricated wall panel integrated with structural insulation and decoration, comprising a concrete structure layer 1, an insulation layer 3 and a hard facing layer 4 arranged in sequence from the inside to the outside, wherein the hard facing layer 4 comprises a plurality of decorative panels arranged at intervals; a plurality of inner anchors 5 are embedded on the back of each decorative panel and near the outer edge of the decorative panel, and the inner anchors 5 of two adjacent decorative panels are arranged one by one, and a top end connected to the concrete structure is connected to each inner anchor 5 and every two corresponding inner anchors 5. The outer anchor 6 is interlocked with the steel mesh or steel cage 2 in the structural layer; the inner anchor 5 is L-shaped, including a lower horizontal plate 53 and an upper vertical plate 51, the two opposite sides of the lower horizontal plate 53 are bent downward to form a facing card 54, and the facing card 54 is embedded in the back of the facing panel, the upper end of the upper vertical plate 51 penetrates the insulation layer 3 and then extends out of the insulation layer 3 and is placed in the concrete structure layer 1, and a strip opening 52 that matches the outer anchor 6 and is arranged horizontally is provided at the position where the upper vertical plate 51 extends out of the insulation layer. In this way, the upper end of the inner anchor 5 is extended out of the insulation layer, and before pouring the concrete structure layer, when the outer anchor 6 is set, since the strip opening 52 is located above the insulation layer 3, the outer anchor can be directly inserted above the insulation layer, and when inserting, the position of the strip opening 52 can be directly observed, which is more convenient for installation. At the same time, since the upper end of the outer anchor 6 is interlocked with the tied steel mesh, the load of the decorative panel can be directly transferred to the concrete structure layer after pouring the concrete, effectively ensuring the stability of the decorative layer on the wall panel. The inner anchor and the decorative panel are connected by embedding the decorative card plate, and the connection method is simple and the connection structure is stable. The inner anchors between two adjacent decorative panels are set one by one, so that only one outer anchor needs to be set between the two corresponding inner anchors to connect with the two inner anchors, which reduces the number of external anchors, effectively improves the efficiency of wall panel production, and saves production costs.

[0038] Specifically, the outer anchor 6 in this embodiment is in the shape of a plate, and both the upper and lower ends are horizontally bent to the same side to form an upper connection part 62 and a lower connection part 61. The lower connection part 61 is sleeved in the strip openings 52 of the two corresponding inner anchors 5, and the upper connection part 62 is buckled in the steel mesh in the concrete structure layer 1. In this way, the outer anchor is in the shape of a plate, and will not tilt after matching with the strip openings 52, which is conducive to construction. The upper and lower ends of the outer anchor are bent on the same side, and after installation, it is not easy to fall off and is more stable. The bent upper connection part can be buckled with the steel mesh in the concrete structure layer, and the lower connection part can match with the strip opening.

[0039] Of course, in a specific implementation, the outer anchor 6 can also be in a columnar shape. The upper and lower ends of the outer anchor 6 can also be horizontally bent to the left and right sides to form the upper connecting part and the lower connecting part.

[0040] The height of the upper plate 51 extending out of the insulation layer is 10 mm-25 mm, and is located below the lower steel bars of the steel cage 2 (or steel mesh), so as not to affect the hoisting of the steel cage 2 .

[0041] In order to match with the facing pallet, two dovetail grooves matching with the facing pallet are provided on the back of each facing panel and at the corresponding position of each internal anchor.

[0042] Specifically, the manufacturing process of the prefabricated wall panel integrated with structural insulation and decoration in this embodiment is as follows:

[0043] Step 1: prefabricate the insulation decorative panel. During prefabrication, assemble the inner anchor on the facing layer in advance and ensure that the upper end extends out of the insulation layer 3 and is 10mm-15mm higher than the upper surface of the insulation layer;

[0044] Step 2, laying a plurality of prefabricated insulation decorative panels on a mold platform according to the design, and closing the mold after processing the gaps between the insulation decorative panels;

[0045] Step 3, hoisting the steel cage (or tying the steel cage);

[0046] Step 4, pass the lower end of the outer anchor through the strip hole on the inner anchor to connect with the inner anchor, and connect the upper end with the steel cage;

[0047] Step 5, pouring concrete;

[0048] Step 6: Maintenance, removal of formwork;

[0049] Step 7: Clean the decorative layer and process the connection gaps.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
