[0001] The utility model belongs to the technical field of thermal insulation exterior wall panels, and relates to a thermal insulation connecting piece for a composite thermal insulation integrated exterior wall panel. Background Art

[0002] In the prior art, the composite thermal insulation integrated exterior wall panel generally has two layers of thermal insulation boards (an outer thermal insulation board and a sandwich thermal insulation board). The thermal insulation connecting piece needs to pass through the two layers of thermal insulation boards at one time. Since the thermal insulation connecting piece is relatively long, when the thermal insulation connecting piece is installed, the connecting piece is likely to be displaced. On the one hand, it will affect the anchoring length of the thermal insulation connecting piece inside the concrete wall. On the other hand, the end part of the thermal insulation connecting piece on the surface of the outer thermal insulation board is uneven, and a relatively thick plastering layer needs to be set, which further affects the flatness of the exterior wall. Content of the Utility Model

[0003] The purpose of the utility model is to provide a thermal insulation connecting piece for a composite thermal insulation integrated exterior wall panel aiming at the above problems.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

The segmented thermal insulation connecting piece comprises an outer connecting piece and an inner connecting piece. The outer connecting piece vertically penetrates the outer thermal insulation board from outside to inside. The inner connecting piece is detachably fixed to the inner end of the outer connecting piece. The outer connecting piece is arranged between the sandwich thermal insulation board and the concrete wall.

[0006] In the above-mentioned thermal insulation connecting piece for a composite thermal insulation integrated exterior wall panel, the outer connecting piece comprises a first sleeve and a first connecting rod arranged in the first sleeve. The first sleeve is arranged in the outer thermal insulation board;

[0007] The inner connecting piece comprises a second sleeve and a second connecting rod arranged in the second sleeve. The second sleeve is arranged in the sandwich thermal insulation board;

[0008] The first connecting rod is inserted into the second sleeve and is detachably connected to the second sleeve. The second connecting rod is inserted into the concrete wall.

[0009] In the above-mentioned thermal insulation connector for the composite thermal insulation integrated exterior wall panel, internal threads are provided in both the first sleeve and the second sleeve, external threads are provided on both the first connecting rod and the second connecting rod, one end of the first connecting rod is screwed to the first sleeve and the other end is screwed to the second sleeve, and one end of the second connecting rod is screwed to the second sleeve and the other end is inserted into the concrete wall.

[0010] In the above-mentioned thermal insulation connector for the composite thermal insulation integrated exterior wall panel, a tail plate is fixedly connected to the outer end of the first sleeve. The tail plate is inserted into the external thermal insulation board and the outer end face of the tail plate is flush with the outer side wall of the external thermal insulation board, and the inner end of the first sleeve is flush with the inner side wall of the external thermal insulation board.

[0011] In the above-mentioned thermal insulation connector for the composite thermal insulation integrated exterior wall panel, both ends of the second sleeve are flush with the two side walls of the sandwich thermal insulation board.

[0016] In the above-mentioned thermal insulation connector for the composite thermal insulation integrated exterior wall panel, the sandwich thermal insulation board is made of B-level thermal insulation material.

[0017] Compared with the existing technology, the advantages of the present utility model are as follows:

[0018] 1. When installing the segmented thermal insulation connector, it only needs to pass the outer connector through the external thermal insulation board and then fix the inner connector on the outer connector, which can avoid the deviation of the connector caused by the excessive length of the thermal insulation connector, so as to prevent the problem of uneven surface of the external thermal insulation board caused by the deviation of the thermal insulation connector.

Detailed Description of the Embodiment

[0025] As Figures 1 - 3 shown, a thermal insulation connecting member for a composite thermal insulation integrated exterior wall panel includes an external thermal insulation board 1, a sandwich thermal insulation board 2, and a concrete wall 3 arranged in sequence from outside to inside. A plurality of segmented thermal insulation connecting members 4 are arranged between the external thermal insulation board 1, the sandwich thermal insulation board 2, and the concrete wall 3. The segmented thermal insulation connecting member 4 includes an outer connecting member 5 and an inner connecting member 6. The outer connecting member 5 vertically penetrates the external thermal insulation board 1 from outside to inside, and the inner connecting member 6 is detachably fixed to the inner end of the outer connecting member 5. The outer connecting member 5 is arranged between the sandwich thermal insulation board 2 and the concrete wall 3.

[0026] In the present utility model, when installing the segmented thermal insulation connecting member 4, it only needs to pass the outer connecting member 5 through the external thermal insulation board 1 and then fix the inner connecting member 6 to the outer connecting member 5, which can avoid the deviation of the connecting member caused by the excessive length of the thermal insulation connecting member, prevent the problem of uneven surface of the external thermal insulation board caused by the deviation of the thermal insulation connecting member, and thus there is no need to shorten the overall length of the thermal insulation connecting member to prevent the deviation of the connecting member, so as to ensure the anchoring length of the thermal insulation connecting member in the concrete wall.

[0027] During installation, the outer connecting member 5 can be first installed on the external thermal insulation board. Since the length of the outer connecting member 5 is relatively short, it can be ensured that there is no installation deviation when the outer connecting member 5 is installed on the external thermal insulation board, which can improve the flatness of the outer surface of the external thermal insulation board. Subsequently, the inner connecting member and the outer connecting member are combined and fixed. After the inner connecting member is fixed, the sandwich thermal insulation board is installed, and finally, a concrete wall is formed by pouring.

[0028] Specifically, the outer connecting member 5 includes a first sleeve 7 and a first connecting rod 8 arranged inside the first sleeve 7. The first sleeve 7 is arranged inside the external thermal insulation board 1; the inner connecting member 6 includes a second sleeve 9 and a second connecting rod 10 arranged inside the second sleeve 9. The second sleeve 9 is arranged inside the sandwich thermal insulation board 2; the first connecting rod 8 is inserted into the second sleeve 9 and is detachably connected to the second sleeve 9, and the second connecting rod 10 is inserted into the concrete wall 3. The detachable connection between the first connecting rod 8 and the second sleeve 9 can realize the installation of the outer connecting member inside the external thermal insulation board and then fix the inner connecting member on the outer connecting member. Therefore, when installing the thermal insulation connecting member, there is no need to consider the overall length of the thermal insulation connecting member, and only the length of the outer connecting member needs to be considered, so as to avoid the installation deviation of the connecting member caused by the overlong thermal insulation connecting member.

[0029] Specifically, internal threads are provided inside both the first sleeve 7 and the second sleeve 9, external threads are provided on both the first connecting rod 8 and the second connecting rod 10. One end of the first connecting rod 8 is screwed to the first sleeve 7 and the other end is screwed to the second sleeve 9, and one end of the second connecting rod 10 is screwed to the second sleeve 9 and the other end is inserted into the concrete wall 3. The screwing connection between the first connecting rod 8 and the second sleeve 9 can realize the rapid assembly and disassembly of the outer connecting member and the inner connecting member.

[0030] Preferably, a tail plate 11 is fixedly connected to the outer end of the first sleeve 7. The tail plate 11 is inserted into the external thermal insulation board 1 and the outer end face of the tail plate 11 is flush with the outer side wall of the external thermal insulation board 1, and the inner end of the first sleeve 7 is flush with the inner side wall of the external thermal insulation board 1. Arranging a tail plate at the outer end of the first sleeve 7 can improve the pull-out bearing capacity of the thermal insulation connecting member.

[0032] Preferably, a first plastic sleeve 12 with external threads is fixedly connected to the outside of the first sleeve 7. Arranging the first plastic sleeve 12 with external threads can improve the connection strength between the first sleeve and the external thermal insulation board.

[0033] Preferably, a second plastic sleeve 13 with external threads is fixedly connected to the outside of the second sleeve 9. Arranging the second plastic sleeve 13 with external threads can improve the connection strength between the second sleeve and the sandwich thermal insulation board.

[0034] Preferably, an anchor 14 is screwed to one end of the second connecting rod 10 away from the second sleeve 9, and the anchor 14 is disposed within the concrete wall 3. The provision of the anchor 14 can increase the tensile bearing capacity between the second connecting rod 10 and the concrete wall.

[0035] Specifically, the external thermal insulation board 1 is made of Class A thermal insulation materials. Class A thermal insulation materials include, but are not limited to, graphite-modified cement-based thermal insulation boards, cement foam thermal insulation boards, vitrified microbead thermal insulation mortars, etc.

[0036] Specifically, the sandwich thermal insulation board 2 is made of Class B thermal insulation materials.
