In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0026] Please also read Figures 1 to 5The anchor provided by the utility model is now described. The anchor comprises a support rod 10, a fixing plate 20 and two support members 30; a fixing plate 11 is provided at one end of the support rod 10; the fixing plate 20 is sleeved on the other end of the support rod 10 and is screwed with the support rod 10; the two support members 30 are sleeved on the support rod 10 back to back and are located between the fixing plate 11 and the fixing plate 20, and the ends of the two support members 30 that are away from each other are provided with a clamping groove 321, and the clamping groove 321 is used to clamp the wire mesh 40; wherein the area of ​​the fixing plate 11 and the fixing plate 20 are both larger than the mesh of the wire mesh 40, so that the two can respectively cooperate with one of the support members 30 to clamp the wire mesh 40.

[0027] It should be noted that both the support rod 10 and the fixed plate 20 are provided with threads, and the two are connected by threaded cooperation; the support rod 10 with threads can improve the gripping force with the concrete, and safely and reliably tie the concrete on both sides of the insulation layer; the area of ​​the fixed plate 20 and the fixed plate 11 is larger than the mesh of the wire mesh 40, which limits the movement of the wire mesh 40 and prevents the wire mesh 40 from passing through the fixed plate 20 and the fixed plate 11; after the wire mesh 40 is engaged with the slot 321, the support member 30 abuts against the fixed plate 20 and the fixed plate 11, and cooperates to clamp the wire mesh 40 on both sides of the insulation layer. The wire mesh 40 is limited by the fixed plate 20 and the fixed plate 11, which can prevent the wire mesh 40 from falling due to vibration, which is beneficial to ensure the strength of the concrete wall panel.

[0028] The beneficial effect of the anchor provided by the utility model is that: compared with the prior art, the utility model adopts two support members 30 located between the fixed plate 11 and the fixed disk 20 and sleeved on the support rod 10, and the clamping groove 321 on the support member 30 cooperates with the fixed plate 11 and the fixed member to clamp the steel mesh 40 on both sides of the insulation layer at the same time, so that one anchor can fix the steel mesh 40 on both sides of the insulation layer, thereby improving the anchoring capacity of the anchor member, reducing the occupied volume in the internal space of the casting template 50, and improving the structural strength of the concrete insulation wall panel; the area of ​​the fixed plate 11 and the fixed disk 20 is larger than the mesh of the steel mesh 40, so that the fixed plate 11 and the fixed disk 20 can fix the steel mesh 40 between the support member 30 and the fixed plate 11, and the support member 30 and the fixed disk 20 after the clamping groove 321 clamps the steel mesh 40, thereby preventing the steel mesh 40 from falling off due to vibration, and improving the structural strength of the concrete insulation wall panel.

[0029] In one possible implementation, see Figure 1 and Figure 2 The support member 30 includes a first plate 31 and a second plate 32. The first plate 31 is sleeved on the support rod 10. The second plate 32 is fixedly connected to the first plate 31 and is located on the side of the support rod 10. A slot 321 is provided at the end of the second plate 32 away from the first plate 31.

[0030] It should be noted that the two support members 30 are clamped to the steel mesh sheets 40 on both sides through the clamping grooves 321 on the second plate 32, which can reduce the concrete pouring space occupied by the anchors compared with conventional anchors, so that the concrete insulation wallboard has higher strength.

[0031] In one possible implementation, see Figure 2 and Figure 3 The support member 30 includes two second plates 32 , which are respectively located on both sides of the support rod 10 , and the clamping grooves 321 on the two second plates 32 are respectively used to clamp two longitudinally adjacent steel wires of the steel wire mesh 40 .

[0032] It should be noted that the two second plates 32 can be triangular in shape, and the slots 321 are provided at the top ends of the two second plates 32. The spacing of the slots 321 on the second plates 32 is the spacing between two adjacent steel wires of the wire mesh 40. It can cooperate with the fixed plate 20 and the fixed plate 11 to clamp the two adjacent steel wires of the wire mesh 40, and can constrain the longitudinal movement of the wire mesh 40, so that the wire mesh 40 can be stably and quickly fixed and assembled.

[0033] In one possible implementation, see Figure 2 and Figure 3 The two second plates 32 are parallel to each other and are vertically arranged on the first plate 31. The two second plates 32 extend into the same mesh of the steel wire mesh 40 and respectively abut against two steel wires that are adjacent to each other in the horizontal direction of the steel wire mesh 40.

[0034] It should be noted that the two second plates 32 are relatively far apart on both sides and can constrain the lateral movement of the wire mesh 40. Together with the slots 321 that constrain the longitudinal movement of the wire mesh 40, the wire mesh 40 can be fixed on both sides of the insulation layer to prevent the wire mesh 40 from falling off due to vibration, thereby ensuring the strength of the concrete insulation wall panels. The two second plates 32 are parallel to each other and arranged in an obliquely symmetrical manner. The arrangement direction of the second plates 32 is parallel to the direction of pouring concrete, thereby avoiding obstruction of the flow of concrete and improving the density of concrete.

[0035] In one possible implementation, see Figure 2 , reinforcing ribs 322 are connected to both sides of the second plate 32 , and the reinforcing ribs 322 are fixedly connected to the first plate 31 .

[0036] It should be noted that each second plate 32 may be provided with two reinforcing ribs 322 , and the material of the reinforcing ribs 322 may be polypropylene, polyethylene, ABS, etc., which are injection molded integrally and are used to strengthen and fix the second plate 32 to prevent the second plate 32 from bending during transportation and production.

[0037] In one possible implementation, see Figure 2A through hole 33 is provided at the center of the first plate 31 , and the through hole 33 is used to align the mesh center of the steel wire mesh 40 .

[0038] It should be noted that the through hole 33 is located at the center of the mesh hole on the wire mesh 40, which helps to align and fix the support members 30 on both sides of the insulation layer.

[0039] In one possible implementation, see Figure 4 A connecting piece 21 is provided on the fixing plate 20 , and the connecting piece 21 is threadedly engaged with the supporting rod 10 .

[0040] It should be noted that the connecting piece 21 can be a nut made of high mechanical strength materials such as metal, fiberglass, ABS and nylon; the connecting piece 21 is provided with a thread inside, and the connecting piece 21 and the support rod 10 thread cooperate, so that the fixed plate 20 cooperates with the card slot 321 to clamp the wire mesh 40, so that the fixed plate 20 presses the steel wires on the four sides of a mesh hole of the wire mesh 40 to prevent the wire mesh 40 from falling off, thereby improving the casting strength of the concrete insulation wall panel.

[0041] In one possible implementation, see Figure 5 The two ends of the support rod 10 pass through the fixing plate 11 and the fixing plate 20 respectively and are used to abut and support on the casting template 50 respectively, so that a grouting gap is formed between the steel wire mesh 40 and the casting template 50.

[0042] It should be noted that the support rod 10 is passed through the interior of the insulation layer and both ends thereof pass through the fixed plate 11 and the fixed disk 20. The length of the support rod 10 is greater than the thickness of the insulation layer. The thickness of the poured concrete is affected by the length of the support rod 10. The longer the support rod 10, the greater the thickness of the poured concrete. There are two casting templates 50, and both ends of the support rod 10 are respectively abutted against the two casting templates 50. The fixed plate 11 and the fixed disk 20 restrict the wire mesh 40 between the casting template 50 and the insulation layer, so that a certain distance is maintained between the wire mesh 40 and the casting template 50, so that two grouting gaps are formed between the wire mesh 40 and the casting template 50, thereby avoiding the contact between the wire mesh 40 and the casting template 50, causing adverse effects such as exposed reinforcement after casting.

[0043] In one possible implementation, see Figure 5 , the support rod 10 is a glass fiber rod or a stainless steel rod.

[0044] It should be noted that the support rod 10 can be made of high-strength glass fiber reinforcement or stainless steel. It can be used in passive ultra-low energy consumption buildings to effectively reduce the point thermal bridge caused by the anchors and safely and reliably tie the concrete on both sides of the insulation layer; the two ends of the support rod 10 support the casting formwork 50, so that there is a certain internal space between the casting formwork 50 on both sides of the insulation layer and the insulation layer, ensuring that there are concrete cavities on both sides of the insulation layer, so that the concrete can be smoothly poured into the casting formwork 50 to complete the casting of the insulation wall panel.

[0045] The utility model embodiment also provides a thermal insulation wall panel, including a tie piece.

[0046] It should be noted that the thermal insulation wall panel also includes thermal insulation material, concrete structural layer and steel wire mesh 40; the actual assembly method of the thermal insulation wall panel is: by pre-arranging the panels and setting the tie pieces at the distribution positions of the steel wire mesh 40, the support members 30 are fixed to the steel wire mesh 40 according to the set positions; the steel wire mesh 40 with the fixed support members 30 is laid flat on the surface of the thermal insulation material; the support rod 10 is passed through the steel wire mesh 40, the support member 30 and the thermal insulation material in sequence; the thermal insulation material is placed on its side and The support member 30 with the wire mesh 40 fixed thereon is installed on the support rod 10 passing through the other side of the material, and the support rod 10 passes through each through hole 33 in turn; the fixing plate 20 is fixed to the support rod 10, and the fixing plate 20 presses the four side wires of one mesh of the wire mesh 40; after the thermal insulation material is placed on its side, a casting template 50 is set at both ends of the support rod 10, and a grouting cavity for pouring concrete is formed between the casting template 50 and the thermal insulation material. After the grouting is completed, the casting template 50 is removed for maintenance.

[0047] The beneficial effect of the thermal insulation wall panel provided by the utility model is that compared with the prior art, the utility model adopts tie pieces to fix the steel mesh 40 on both sides of the thermal insulation material in the concrete structural layer. Compared with the prior art in which the tie pieces can only fix the steel mesh 40 on one side, the utility model can reduce the occupied volume in the concrete structural layer and improve the structural strength of the thermal insulation wall panel.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
