DETAILED DESCRIPTION

[0032] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In the description of the present utility model, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0034] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0035] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0036] like Figure 1-5 As shown, this embodiment proposes an external high-precision non-disassembly external template fixing connector, which mainly includes the following structure:

[0037] The fixing plate 1 and the anchor rod 2 are fixedly connected to the bottom of the fixing plate 1. The cross-sections of the fixing plate 1 and the anchor rod 2 are both circular, and the fixing plate 1 and the anchor rod 2 are coaxial. The bottom of the anchor rod 2 is connected to an anchor tip 3, and the anchor tip 3 is an overall pointed cone structure.

[0038] The anchor 2 also includes an insertion hole 61 provided at the axial center of the fixing plate 1, the insertion hole 61 extending downward to the upper end of the anchor rod 2, and at least two sets of symmetrical positioning holes 62 are provided at the upper end of the anchor rod 2, the positioning holes 62 are connected with the insertion hole 61; the anchor cover 5 is also included, and the bottom of the cap is provided with two symmetrical plug posts 63. In this embodiment, the plug posts 63 are rectangular columns, and there is a gap between the two plug posts 63. The bottom ends of the plug posts 63 are provided with outwardly extending protrusions 64, and the maximum distance between the two protrusions 64 is slightly larger than the diameter of the insertion hole 61. Because there is a gap between the two plug posts 63, when the two protrusions 64 are first inserted into the inside of the insertion hole 61, the two protrusions 64 will shrink toward the gap, so that the protrusion 64 can be squeezed into the insertion hole 61 as a whole. When the two plug posts 63 and the protrusions 64 are inserted to the bottom of the insertion hole 61, the two protrusions 64 pop up outward and are fixed at the positioning holes 62. In this embodiment, the protrusion 64 is a right-angled trapezoidal structure, wherein the tip portion faces downward and the top is a horizontal plane. When the protrusion 64 is stuck in the positioning hole 62, most of the horizontal plane is outside the positioning hole 62, further preventing the anchor cover 5 from being pulled up.

[0039] A rib plate 65 is fixedly connected between the two plug posts 63, and the rib plate 65 is located above the protrusion 64. The rib plate 65 can reduce the space for the two plug posts 63 to shrink inward to a certain extent, so that the two plug posts 63 need a certain amount of force to shrink inward, and avoid the problem of the plug posts 63 being pulled out of the insertion holes 61 due to accidental touch after the protrusion 64 is inserted into the positioning hole 62. Through this design, the steel wire mesh 10 is fastened to the fixing plate 1, and the fixing method is quick and convenient.

[0040] Furthermore, the top surface of the fixed disk 1 is connected with a raised strip 7 connected end to end. In this embodiment, the raised strip 7 is in the shape of a ring and also includes reinforcing ribs between adjacent insertion holes 61. The bottom surface of the reinforcing ribs is connected to the fixed disk 1, and the side wall of the reinforcing ribs is connected to the raised strip 7. The raised strip 7 is used in conjunction with the reinforcing ribs to further enhance the strength of the fixed disk 1 and prevent it from bending due to external forces. The fixed disk 1 is provided with a plurality of holes 4 in a circumferential array. The holes 4 are fan-shaped in this embodiment. The holes 4 are used to reduce the overall weight. A through hole 12 is provided on the anchor cover 5. When applying the slurry, the slurry passes through the through hole 12 to better contact the steel mesh 10.

[0041] Furthermore, the anchor rod 2 is divided into an upper rod portion 21, a middle rod portion 22 and a bottom rod portion 23 from top to bottom; wherein the upper portion is a smooth cylindrical surface, and the middle portion and the bottom portion are fixedly connected with a plurality of annular barbs 9 evenly distributed up and down; the cross section of the annular barbs 9 is triangular. The annular barbs 9 increase the resistance between the anchor rod 2 and the poured concrete wall 11, so that the anchor rod 2 is more firmly fixed to the concrete wall 11.

[0042] Furthermore, the upper portion 21 of the rod is fixedly connected with an upper wing 21a, the middle portion 22 of the rod is fixedly connected with a middle wing 22a, and the bottom portion 23 of the rod is fixedly connected with a lower wing 23a; wherein the angles between the upper wing 21a, the middle wing 22a, and the lower wing 23a and the anchor rod 2 are all less than 90 degrees, so that the above-mentioned wings all extend toward the fixing plate 1. The above-mentioned wings increase the bite force between the anchor rod 2 and the insulation board 13 and the concrete wall 11 after the anchor rod 2 is fully driven in, thereby preventing the anchor rod 2 from being pulled out.

[0043] Furthermore, the angle between the upper wing 21a and the anchor rod 2 is greater than the angle between the middle wing 22a and the lower wing 23a and the anchor rod 2; in the process of driving the anchor rod 2 into the insulation board 13, the angle between the wing of the middle part 22 of the rod and the bottom 23 of the rod is smaller, so it is easy to drive the anchor rod 2 into the insulation board 13 first, and the angle of the wing of the upper part 21 of the rod is relatively large, which can increase the bite force between the anchor rod 2 and the insulation board 13 after it is fully driven in, and prevent the anchor from being pulled out. Among them, the tightness of the lower wing 23a is greater than that of the upper wing 21a, and the tightness of the upper wing 21a is greater than that of the middle wing 22a; arranging the wings in this way increases the stability of the anchor rod 2 in the insulation board 13, and at the same time increases the stability after being fixed to the concrete wall 11.

[0044] It also includes a supporting rib 23b, one end of which is fixedly connected to the lower wing 23a, and the other end of which is fixedly connected to the bottom of the rod 23; the strength of the lower wing 23a is enhanced by reinforcing ribs 8 to prevent the lower wing 23a from being deformed or broken by the tension, and to prevent the anchor rod 2 from being deformed when passing through the insulation board 13, so that the lower wing 23a maintains a certain angle with the anchor rod 2, further enhancing the tension between the first barb and the concrete wall 11.

[0045] It is worth noting that the fixing plate 1, the anchor rod 2 and the anchor tip 3 are all one-piece molded structures, and their materials include but are not limited to nylon, PP, PC or PE; the material of the anchor cover 5 includes but is not limited to nylon, PP, PC or PE.

[0046] As shown in the figure, the specific operating principle of the device is as follows:

[0047] The anchor rods 2 in several fixed connecting parts are pre-pierced through the insulation board 13. Since several groups of fins with different angles and densities are provided on the anchor rods 2, it is difficult to remove the anchor rods 2 from the insulation board 13 after penetration. After the insulation board 13 and the fixed connecting parts fixed as one are transported to the construction site, a template for pouring the concrete wall 11 is formed in conjunction with the steel template, and then the concrete is poured. After the concrete is formed, the insulation board 13 is tightly combined with the front part of the concrete under the action of the anchor rods 2.

[0048] Subsequently, the grid in the wire mesh 10 is aligned with the fixed plate 1, and the wire mesh 10 is clamped between the anchor cover 5 and the fixed plate 1 through the anchor cover 5; during the process of clamping the anchor rod 2 and the fixed plate 1, the two plug posts 63 are inserted into the insertion hole 61 of the fixed plate 1 until the protrusion 64 reaches the position of the positioning port 62. Since the maximum distance between the two protrusions 64 is greater than the diameter of the insertion hole 61, the protrusion 64 squeezed into the insertion hole 61 reaches the position of the positioning port 62 and then bounces outward, so that the protrusion 64 is fixed at the position of the positioning hole, thereby achieving the clamping of the wire mesh 10 between the anchor cover 5 and the fixed plate 1.

[0049] Repeat the above steps to align several grids in the wire mesh 10 with several fixed disks 1 on the insulation board 13, and then fix the wire mesh 10 on the fixed disk 1 through the anchor cover 5; at this time, the wire mesh 10 is clamped as a whole between the anchor cover 5 and the fixed disk 1, and fixed on the outer side of the insulation board 13, which is convenient for subsequent construction.

[0050] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate 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 claims and their equivalents.
