[0034] As shown in Figures 1 to 7 The present embodiment proposes a building thermal insulation connecting piece, which comprises a main rod 4, two ends of the main rod 4 are detachably connected with clamping discs 5, and a clamping space 6 for clamping a thermal insulation board 1 is formed between the two clamping discs 5; further comprising a positioning unit 7 for positioning a steel mesh, at least one set of the positioning unit 7 is detachably connected to one end of the main rod 4; wherein the positioning unit 7 comprises a positioning disc 71, the positioning disc 71 is detachably connected with the end of the main rod 4, and two sets of outwardly expanding screw rods 72 are arranged on the side away from the main rod 4, which are symmetrically distributed in the shape of "eight" character; the opposite sides of the two screw rods 72 are respectively provided with semicircular grooves 73, and the two semicircular grooves 73 are matched to form a positioning space 74 for clamping a vertical rib 21 of the steel mesh; the positioning unit 7 further comprises a limiting cover 75, an internal thread section 76 is arranged on the inner wall of the limiting cover 75, the internal thread section 76 is matched with the external threads of the two screw rods 72, so that the limiting cover 75 can be sleeved on the screw rod 72 and axially moved along the screw rod 72, when the limiting cover 75 is sleeved on the screw rod 72, the limiting cover 75 is screwed, so as to drive the two screw rods 72 to close to clamp and fix the vertical rib 21.

[0035] The utility model discloses a building thermal insulation connecting piece whole adopts the design of modularization detachable, and the detachable connection between main rod 4 and two chuck plates 5 can realize the quick clamping of thermal insulation board 1 and the self -adaptation adjustment of thickness, and the detachable connection between positioning unit 7 and main rod 4 cooperates with the screw rod 72 and the limiting cover 75 of symmetrical distribution to form the clamping mechanism of screw thread linkage, and through the screwing limiting cover 75 drives two screw rods 72 to close inwards, can complete the annular hoop clamping of vertical muscle 21 in steel wire mesh frame 2, and clamping action is efficient and clamping is uniform and stable. This operation mode is simple and direct, need not complex tool and tedious step, greatly shortens the installation time, and improves construction efficiency.

[0036] Further, the building thermal insulation connecting piece adopts main rod 4, chuck plate 5, positioning disc 71, screw rod 72 and limiting cover 75, and the components can be manufactured through common processing technology, and the standardization design between the components makes the production process easy to control, does not need complex processing procedure, effectively reduces production cost, improves production efficiency, and is suitable for mass industrial production. If individual components are damaged during use, the whole connecting piece does not need to be replaced, and the damaged components can be quickly removed and replaced through the detachable connection between the components. The design can further reduce the maintenance cost of the building thermal insulation connecting piece and reduce the maintenance time.

[0037] In different construction environments, positioning unit 7 can be selectively installed at one end or both ends of main rod 4 to realize flexible switching of single-sided or double-sided steel wire mesh frame 2, and meet diversified construction requirements such as single-sided thermal insulation or double-sided reinforcement.

[0038] In some embodiments, internal threads are formed at both ends of main rod 4, a bolt 8 is fixedly connected to the side opposite to main rod 4, and the bolt 8 is threadedly connected with the above-mentioned internal thread hole 41. In the building thermal insulation system, the connecting piece needs to bear certain tension, pressure and vibration, and this stable connection mode can ensure the safety and reliability of the whole structure. The distance between steel wire mesh frame 2 and thermal insulation board 1 will affect the heat transfer performance of the thermal insulation system, and the threaded connection can enable the staff to flexibly respond according to the actual situation, allowing the distance between thermal insulation board 1 and steel wire mesh frame 2 to be adjusted within a certain range. If it is found that the components in positioning unit 7 are damaged or defective during construction, the positioning unit 7 can be quickly disassembled and repaired or replaced through the threaded connection.

[0039] In some embodiments, the threaded rods 72 are in a cylindrical configuration when closed, and are in a semi-cylindrical configuration when separated. In the initial state, the threaded rods 72 are in a semi-cylindrical configuration and are spread outwards, so that the vertical reinforcement bars 21 of the reinforcement mesh can be easily placed between the two threaded rods 72, greatly simplifying the installation steps of the reinforcement mesh, and the operator does not need to spend too much effort to adjust the position of the vertical reinforcement bars 21, and can quickly complete the preliminary installation of the vertical reinforcement bars 21; then the limiting cover 75 is screwed in, and the inner threaded segment 76 of the limiting cover 75 cooperates with the outer thread of the threaded rod 72 to drive the two threaded rods 72 to gradually close to form a cylindrical configuration, which can uniformly apply clamping force around the vertical reinforcement bars 21, so that the vertical reinforcement bars 21 are stably constrained in the circumferential direction, ensuring the stability of the connection between the reinforcement mesh 2 and the main rod 4.

[0040] In some embodiments, the outer surface of the positioning disc 71 is provided with a plurality of groups of positioning grooves 77 for clamping the horizontal reinforcement bars 22 of the reinforcement mesh 2. Specifically, the opening of the positioning groove 77 can be a circular arc groove with a radius smaller than that of the standard horizontal reinforcement bar 22, and the positioning disc 71 is made of plastic material. The design of the positioning groove 77 can further position the horizontal reinforcement bar 22. During the process of moving the vertical reinforcement bar 21 transversely into the positioning space 74, the construction personnel can press the horizontal reinforcement bar 22 into the positioning groove 77; the positioning groove 77 forms a certain binding force on the horizontal reinforcement bar 22, and with the subsequent screwing of the limiting cover 75, the vertical reinforcement bar 21 is clamped and pressed against the vertical reinforcement bar 21, which can clamp the horizontal reinforcement bar 22 between the positioning disc 71 and the limiting cover 75, further positioning the horizontal reinforcement bar 22 inside the positioning groove 77, so that the reinforcement mesh is firmly connected with the main rod 4 and the positioning unit 7.

[0041] In some embodiments, the limiting cover 75 is internally provided with a circular truncated cone-shaped recess 78 that is inwardly tapered, and the recess 78 is in communication with the area of the inner threaded segment 76. The design of the recess 78 is mainly for its guiding effect. Since the threaded rod 72 is in an outwardly expanded state in the initial state, it will be difficult to guide it into the limiting cover 75 and cooperate with the inner threaded segment 76 without a suitable guide. With this recess 78, the threaded rod 72 can quickly enter the limiting cover 75 without needing to spend more effort to adjust the angle and position of the two threaded rods 72, just by roughly aligning the recess 78 of the limiting cover 75, under the guidance of the recess 78, the threaded rod 72 can smoothly enter and quickly cooperate with the inner threaded segment 76, greatly improving the installation efficiency.

[0042] In some embodiments, the threaded rods 72 are made of elastic materials, specifically spring steel, nylon, or elastic rubber composites (composite materials made by adding reinforcing fibers to a rubber matrix). These materials possess a certain degree of elasticity and toughness. The toughness allows them to withstand significant external impacts without breaking, such as during concrete pouring and transportation. This material can better maintain the integrity of the structure and prevent easy damage. The elasticity ensures that it undergoes a certain deformation under stress, allowing the threaded rods 72 to expand outward in the initial state and gradually close to clamp the vertical ribs 21 when threadedly connected to the limiting cap 75. When faced with vertical ribs 21 with slight differences in thickness, it can also adapt through elastic deformation, ensuring a good clamping effect.

[0043] In some embodiments, the main rod 4 is made of fiber-reinforced composite material, aluminum alloy, or alloy steel. These types of materials are characterized by corrosion resistance, light weight, and high strength. The high strength allows it to withstand greater tensile and compressive forces. In the construction environment of building insulation connectors, the main rod 4 needs to bear the weight of components such as the wire mesh frame 2 and the insulation board 1. The high-strength material of the main rod 4 can ensure the structural stability and safety of the connector.

[0044] This utility model also proposes a wire mesh frame 2 insulation board, which includes an insulation board 1, with wire mesh frames 2 spaced apart on both sides or one side of the insulation board 1; it also includes the above-mentioned building insulation connector, in which the main rod 4 of the building insulation connector passes through the insulation board 1 and is clamped and fixed by two clamping plates 5, the vertical ribs 21 of the wire mesh frame 2 are located in the positioning space 74 of the positioning unit 7, the horizontal ribs 22 are located in the positioning groove 77, and the limiting cover 75 is screwed on so that the steel mesh is positioned between the limiting rod and the positioning plate 71.

[0045] The specific construction method of the insulation wall formed by the steel wire mesh frame and insulation board is as follows:

[0046] S1: Insert the main rod 4 through the pre-set hole in the insulation board 1, and then screw the two clamps 5 so that the two clamps 5 are respectively connected to the two ends of the main rod 4 to clamp the insulation board 1 through the threaded connection.

[0047] S2: Reference Figure 2 or Figure 6 A positioning unit 7 is connected to one or both ends of the pole, corresponding to the installation of single-sided or double-sided wire mesh frame 2 respectively;

[0048] S3: Move the vertical rib 21 in the wire mesh frame 2 horizontally into the clamping space 6 formed by the two threaded rods 72, and the horizontal rib 22 is inserted into the positioning groove 77; screw the limiting cover 75, the threaded section inside it is threadedly connected to the two threaded rods 72, drive the two threaded rods 72 to close inward until the vertical rib 21 is clamped, and at the same time the end face of the limiting cover 75 indirectly presses the horizontal rib 22.

[0049] S4: erecting the outer formwork 3, making the steel mesh frame 2 between the outer formwork 3 and the thermal insulation board 1, pouring concrete, and after the concrete is shaped, the thermal insulation wall is formed.

[0050] The above describes the specific embodiments of the utility model in combination with the drawings, but is not a limitation on the protection scope of the utility model, and various modifications or changes made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
