Description

Technical Field

[0001] The utility model belongs to the technical field of assembled buildings, and in particular relates to a wall thermal break connector suitable for various wall widths. Background Art

[0002] IPS (Integrated Precast Shearwall) wall is an integrated prefabricated shear wall system, which is constructed by the traditional method of pouring concrete. It has the advantages of fast construction speed, controllable quality, and good seismic performance. It consists of a protective layer, an insulation layer, and a structural layer. The protective layer and the structural layer are both cast-in-place reinforced concrete structures, and the insulation layer uses insulation boards. During construction, it is necessary to ensure that the position of the insulation layer does not deviate into the structural layer, and at the same time ensure that the thickness of the protective layer and the structural layer is appropriate. In order to ensure that the thickness of the protective layer, the insulation layer, and the structural layer meet the requirements of the design and relevant construction specifications, the existing construction technology requires the use of steel hooks or connectors to fix the steel trusses and insulation boards on both sides.

[0003] The Chinese patent (CN218758080U) previously applied by the inventor discloses a reinforced foam lightweight concrete wall connector, which is easy to implement standardized operations and can be applied to walls with different thicknesses of insulation layers. However, with the development of prefabricated buildings, according to different regions and different use environment requirements, the current IPS energy-saving wall will not only change in the insulation layer, but also in the thickness of the protective layer and the structural layer. When the thickness of the protective layer and the structural layer changes, it is necessary to design and manufacture wall connectors of different lengths, and different specifications of wall connectors require the design and manufacture of molds of different specifications, resulting in high mold costs and high production costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a wall thermal break connector suitable for various wall widths, which is beneficial to reducing mold costs and production costs.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a wall thermal break connector suitable for various wall widths, including a connecting rod, and two insulation layer positioning parts that can be adjusted and moved left and right along the length direction of the rod body are arranged in the middle of the connecting rod; more than two steel bar positioning grooves are distributed at both ends of the connecting rod along the length direction of the rod body, and a protective layer positioning part of a set length is respectively arranged on the outer side of each of the steel bar positioning grooves, and there is a breaking opening between adjacent protective layer positioning parts.

[0006] As a preferred technical solution, the connecting rod is made of thermal break material.

[0007] As a preferred technical solution, the connecting rod is connected to the insulation layer positioning piece through threaded fitting.

[0008] As a preferred technical solution, two sections of external threads are provided in the middle of the connecting rod, and a thermal insulation layer positioning piece is threadedly connected to each section of the external thread.

[0009] As a preferred technical solution, the thermal insulation layer positioning member includes an adjusting sleeve threadedly connected to the connecting rod, and a positioning plate is fixedly provided on the inner end of the adjusting sleeve.

[0010] As a preferred technical solution, a plurality of reinforcing ribs are provided between the positioning plate and the adjusting sleeve.

[0011] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0012] (1) Two or more steel bar positioning grooves are distributed along the length direction of the rod body at both ends of the connecting rod, so that the steel bar positioning grooves at both ends are respectively positioned with the steel bar trusses on both sides of the insulation layer, thereby ensuring the spacing between the steel bar trusses on both sides; two insulation layer positioning pieces are mounted on the connecting rod, and the position of the insulation layer (insulation board) is limited by the two insulation layer positioning pieces to prevent it from deviating into the structural layer, thereby ensuring the thickness of the structural layer; the two insulation layer positioning pieces can be adjusted and moved left and right along the rod body direction of the connecting rod, so that it can be suitable for walls with different thicknesses of insulation layers.

[0013] (2) A protective layer positioning portion of a set length is correspondingly arranged on the outer side of each of the steel bar positioning grooves, and a break opening is provided between adjacent protective layer positioning portions, so that the break position of the protective layer positioning portion can be selected according to the thickness of the wall, thereby being applicable to IPS walls of different thicknesses and meeting different energy-saving requirements in different regions.

[0021] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0022] like Figure 1 As shown, a wall thermal break connector suitable for various wall widths includes a connecting rod 1. The connecting rod 1 is preferably made of a thermal break material, such as nylon 66, epoxy resin, vinyl fiber, alkali-free glass fiber or basalt fiber, to slow down heat conduction.

[0023] Two insulation layer positioning members 2 which can be adjusted and moved left and right along the length direction of the rod body are arranged in the middle part of the connecting rod 1. The position of the insulation layer (insulation board) is limited by the two insulation layer positioning members 2 to prevent it from deviating into the structural layer, thereby ensuring the thickness of the structural layer; the two insulation layer positioning members 2 can be adjusted and moved left and right along the rod body direction of the connecting rod 1, so that it can be suitable for walls with insulation layers of different thicknesses.

[0024] In this embodiment, the connecting rod 1 is connected to the thermal insulation layer positioning member 2 by threaded matching, so that the adjustment operation is convenient. The connecting rod 1 is provided with two sections of external threads, and the thermal insulation layer positioning member 2 is threadedly connected to each section of the external threads.

[0025] refer to Figure 1 and Figure 2 In this embodiment, the thermal insulation layer positioning member 2 includes an adjusting sleeve 21 threadedly connected to the connecting rod 1, and a positioning plate 22 is fixedly provided at the inner end of the adjusting sleeve 21. The inner side of the positioning plate 22 is pressed against the side of the thermal insulation board to prevent the positioning plate from deviating into the structural layer during pouring, thereby ensuring the thickness of the structural layer. Preferably, a plurality of reinforcing ribs 23 are provided between the positioning plate 22 and the adjusting sleeve 21. The reinforcing ribs 23 distributed at intervals not only play a role in reinforcing the thermal insulation layer positioning member, but also facilitate the application of force during rotation adjustment.

[0026] refer to Figure 1At both ends of the connecting rod 1, there are more than two steel bar positioning grooves 3 distributed along the length direction of the rod body. In this embodiment, three steel bar positioning grooves 3 are used as an example for illustration. When in use, the steel bar positioning grooves 3 at appropriate positions on both ends are respectively engaged and positioned with the transverse steel bars of the steel bar trusses on both sides of the insulation layer, thereby ensuring the spacing between the steel bar trusses on both sides. A protective layer positioning portion 4 of a set length (each section is 50 mm, of course, it can also be other lengths) is correspondingly arranged on the outside of each of the steel bar positioning grooves 3, and a breaking opening 5 is provided between adjacent protective layer positioning portions 4. In this way, the breaking position of the protective layer positioning portion 4 can be selected according to the thickness of the wall, so that it can be suitable for IPS walls of different thicknesses and meet different regions and different energy-saving requirements.

[0027] refer to Figure 3 When the wall thickness (H1 is 300mm) is large, it is not necessary to break off the protective layer positioning parts 4 and can be used directly; Figure 4 When the wall thickness (H2 is 250mm) is moderate, a section of the protective layer positioning part 4 (the dotted line part is the broken part) is broken off from the outermost breaking openings 5 ​​at both ends of the connecting rod 1 and it can be used. Figure 5 When the wall thickness (H3 is 200mm) is small, two sections of the protective layer positioning parts 4 (the dotted line part is the broken part) are broken from the second outer side breaking openings 5 ​​at both ends of the connecting rod 1 and it can be used.

[0028] In summary, the wall connector is suitable for walls with different thicknesses of insulation layers, and can also be used for walls with different thicknesses of protective layers or structural layers. It can be produced using a pair of molds, with low mold costs, low unit production costs, and a wide range of applications.

[0029] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
