Description

Technical Field

[0001] The utility model belongs to the technical field of building material application, and particularly relates to a connector for a steel wire mesh composite insulation board system. Background Art

[0002] During the construction of cast-in-place concrete for external wall insulation, the main steel cage, insulation board and wire mesh are successively set up between the inner and outer formworks, and then concrete is poured into the cavity formed between the insulation board and the inner and outer formworks. After the concrete solidifies, the wire mesh composite insulation board and concrete are formed into one, which has the advantages of firm fixation, long service life and short construction period.

[0003] In order to prevent the insulation board and the steel mesh from moving toward the inner or outer formwork due to the pouring pressure during the pouring process, it is necessary to connect and position the insulation board and the steel mesh through connectors. At present, in order to improve the efficiency of on-site construction, the composite connection of the steel mesh and the insulation board has begun to be promoted and prefabricated in the factory.

[0004] The existing connecting parts are mainly metal plates, on which the fixing parts can be removably fixed. Although this structure can meet the fixing needs of the insulation board and the wire mesh, it is affected by the metal material and has a strong thermal conductivity. Multiple connectors need to be arranged on the insulation board and the wire mesh to ensure stability. These metal connecting parts become heat conductors, thereby invisibly increasing the energy consumption of the building. Utility Model Content

[0005] The utility model aims at the technical problems existing in the existing connectors and proposes a connector for a steel wire mesh composite insulation board system which has a reasonable design, a simple structure, is easy to process and can effectively reduce the heat conduction efficiency and reduce the energy consumption of the building.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. The utility model provides a connector for a steel wire mesh composite insulation board system. By improving the structure of the existing connector, the thermal conductivity of non-metallic hard materials is much lower than that of metal materials, which effectively reduces thermal conductivity and thus reduces the energy consumption of the building.

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Embodiment 1, as Figure 1 to Figure 4 As shown, the present embodiment aims to provide a connector for a steel wire mesh 5 composite insulation board 4 system, thereby reducing the heat conduction efficiency and achieving the purpose of reducing building energy consumption. To this end, the connector for the steel wire mesh 5 composite insulation board 4 system provided in the present embodiment includes a connector body 1 and a positioning member 2 matched with the connector body 1. Different from the existing flat connector, in the present embodiment, the connector body 1 is cylindrical. In order to cooperate with the connector body 1, in the present embodiment, the positioning member 2 is tubular, and the positioning member 2 and the connector body 1 are threadedly connected. Since the positioning member 2 is used to resist the insulation board 4 and / or the steel wire mesh 5, a support ring 21 is mounted on the positioning member 2 to resist the steel wire around the mesh of the steel wire mesh 5. In the present embodiment, in order to facilitate processing, the positioning member 2 and the support ring 21 are integrally arranged, and the support ring 21 is arranged near the bottom of the positioning member 2. Since the connector body 1 is a part that passes through the insulation board 4 and the steel wire mesh 5, in the present embodiment, the material of the connector body 1 is a non-metallic hard material. The non-metallic hard material can be some commonly used materials such as PVC, glass fiber tendons or basalt fiber tendons in construction. In this embodiment, considering the strength, elastic modulus and elongation, glass fiber tendons or basalt fiber tendons are preferred. Of course, it should be noted that in order to maintain the spacing between the insulation board 4 and the steel mesh 5, a support sleeve 6 is also required to be added between the two, and the support sleeve 6 can be sleeved on the connector body 1. The material of the support sleeve 6 is preferably plastic material, and it does not need to be threadedly connected to the connector body 1.

[0022] Through the above arrangement, since the thermal conductivity of the penetrating connector body 1 is low, the heat conduction effect and efficiency are reduced, thereby reducing the energy consumption of the building.

[0023] Considering that the positioning member 2 may be deformed, displaced and damaged during transportation and hoisting, in order to minimize the problems caused by collision, a protective cap 3 is also mounted on the periphery of the positioning member 2. Considering that if there is a gap between the protective cap 3 and the positioning member 2, the positioning member 2 can be protected to the greatest extent. Therefore, in this embodiment, a limiting protrusion 31 is arranged on the inner wall of the protective cap 3. The limiting protrusion 31 is distributed in an annular shape on the inner wall of the protective cap 3. A limiting ring 22 is mounted on the top of the positioning member 2. The limiting ring 22 is between the top of the inner wall of the protective cap 3 and the limiting protrusion 31. In this way, the setting of the limiting ring 22 and the limiting protrusion 31 prevents the protective cap 3 from falling off the positioning member 2. At the same time, the two are not rigidly connected, so that better buffering can be obtained to avoid damage caused by collision.

[0024] Considering that the positioning member 2 needs to be threadedly connected to the connector body 1, and if the protective cap 3 cannot be relatively fixed to the positioning member 2, it is inconvenient to fix and disassemble the protective cap 3 with the connector body 1 only by relying on the support ring 21. For this reason, in the present embodiment, an elastic sheet 23 is also provided on the outer wall of the positioning member 2, one end of the elastic sheet 23 is fixed on the outer wall of the positioning member 2, and the other end is arranged outward, and the elastic sheet 23 is arranged close to the support ring 21. The elastic sheet 23 is distributed in a ring shape on the outer wall of the positioning member 2. At the same time, a toggle protrusion 24 is also provided on the outer wall of the positioning member 2. The toggle protrusions 24 are distributed in a ring shape on the outer wall of the positioning member 2, and the spacing between the toggle protrusions 24 accommodates the passing of the limiting protrusion 31. In this way, normally, supported by the elastic sheet 23 and the toggle protrusion 24, the protective cap 3 and the positioning member 2 are in a relatively rotatable state. When the positioning member 2 needs to be adjusted, the protective cap 3 adjusts the angle so that the angle of the limiting protrusion 31 is between the two adjacent toggle protrusions 24, and then moves toward the support ring 21. At this time, the limiting protrusion 31 enters between the two adjacent toggle protrusions 24. At this time, the protective cap 3 and the positioning member 2 form a relatively fixed connection. At this time, twisting the protective cap 3 can realize the rotation of the positioning member 2, thereby achieving the purpose of adjustment.

[0025] In order to facilitate processing and installation between the protective cap 3 and the positioning member 2, in this embodiment, the positioning member 2 and the protective cap 3 are both made of plastic material, that is, polyethylene, polypropylene or resin material, so that it is convenient to install, and at the same time, the elastic sheet 23 can also be integrally formed by injection molding, thereby reducing production costs.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
