[0031] Among them, at least one positioning member 5 can be detachably installed on the guide rod 2. During installation, one end of the guide rod 2 needs to penetrate through the thermal insulation board 1, so that one positioning member 5 can be optionally fixed on the guide rod 2, and the other positioning member 5 can be detachably installed on the guide rod 2; or both positioning members 5 can be detachably installed on the guide rod 2. Among them, the positioning member 5 comprises a stop disc 51, the outer side of the stop disc 51 is fixedly connected with a positioning disc 52 at intervals, and the positioning disc 52 is provided with two first clamping grooves 53 arranged in a vertical manner; and a pressing disc 54 is detachably separated from the outer side of the positioning disc 52, the inner side of the pressing disc 54 is provided with two second clamping grooves 55 arranged in a vertical manner, the first clamping grooves 53 and the second clamping grooves 55 are oppositely arranged, a clamping space is formed between the first clamping grooves 53 and the second clamping grooves 55, and the steel mesh 3 is placed in the clamping space. Further, a first grout opening is formed on the positioning disc 52 and the pressing disc 54, which facilitates the flow of grout when filling the concrete 4 to cover the positioning member 5.

[0032] In the design, the first clamping grooves 53 and the second clamping grooves 55 position a certain area of the steel mesh 3 to avoid movement in the subsequent pouring process. In the construction industry, there is no detailed provision for the density of the steel mesh 3 in the thermal insulation wall, and designers will choose the appropriate density of the steel mesh 3 according to the specific project requirements and local building specifications. To solve the above problem, the connecting member is designed, and the first clamping grooves 53 and the second clamping grooves 55 are arranged in a vertical manner, only clamping a corner of the steel mesh 3, and simultaneously realizing horizontal and vertical positioning, which can also meet the clamping of steel meshes 3 of different densities, and has a wide range of applications.

Further, the overall width of the two clamping grooves is less than the chord length of the recessed part in the first clamping grooves 53, and the length between the two endpoints of the arc-shaped recessed part is the chord length. Referring to Figure 6 ​, through the design can be achieved for different thickness of steel mesh 3 clamping, if the steel mesh 3 is too thick, through the first slot 53 for limiting, the second slot 55 is used to resist the steel mesh 3 in the first slot 53, if the steel mesh 3 is too thin, can be through the second slot 55 for limiting, the first slot 53 is used to resist the steel mesh 3 in the second slot 55. Through the design of two vertical first slot 53, can be positioned for different density, different thickness of steel mesh 3, wide applicability.

The ends of the reinforcing ribs are fixedly connected with the abutting disc 51 and the positioning disc 52 respectively. The abutting disc 51 and the positioning disc 52 are connected to form a whole through the sleeve 56, so that one or both positioning members 5 can be quickly installed on the guide rod 2. The reinforcing ribs are designed to strengthen the strength between the positioning disc 52 and the abutting disc 51, so that the positioning member 5 has better compression resistance. Further, a plurality of second slurry holes are formed in the reinforcing ribs 57, so that the slurry can flow and cover the positioning member 5 when the concrete 4 is poured.

In this design, the pressing disc 54 is positioned by the bolt 512. When the first slot 53 and the second slot 55 clamp the steel mesh 3, the bolt 512 is inserted through the through hole 511 and cooperates with the threaded hole 510. After the bolt 512 is screwed tightly, the pressing disc 54 is fixed to the current position, so that the pressing disc 54 can be quickly installed. At this time, a part of the guide rod 2 extends to the outside of the pressing disc 54, which is used to control the distance between the pressing disc 54 and the outer formwork, so as to further control the pouring thickness between the insulation board 1 and the outer formwork.

After the first clamping groove 53 clamps the steel mesh 3, the threaded column 515 is screwed with the threaded positioning hole 513 by rotating the rotating head 514, so as to realize the quick installation of the mounting plate. After installation, there is a certain distance between the rotating head 514 and the pressing plate 54, which is used to control the distance between the pressing plate 54 and the outer formwork, so as to further control the pouring thickness between the insulation board 1 and the outer formwork.

[0038] The construction steps of the insulation wall are as follows:

[0039] The guide rod 2 with a positioning member 5 is inserted into the insulation board 1 until the abutting disc 51 is attached to one side of the insulation board 1, and the other positioning member 5 is installed on the other side of the guide rod 2; the steel mesh 3 is aligned and placed in the two first clamping grooves 53, the horizontal and vertical steel bars in the steel mesh 3 are clamped into the two first clamping grooves 53, and then the positioning disc 52 is installed on one side of the positioning disc 52, so as to realize the positioning of the steel mesh 3 through the first clamping groove 53 and the second clamping groove 55; the outer formwork is erected on both sides of the insulation board 1, and the concrete 4 is poured in the outer formwork, and the insulation wall is formed after the concrete 4 is cured and shaped.

[0040] Although the specific embodiments of the application are described above with reference to the drawings, the description is not a limitation on the protection scope of the application, and various modifications or changes made by those skilled in the art on the basis of the technical solutions of the application without creative labor are still within the protection scope of the application.
