Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a curtain wall embedded component for prefabricated reverse-insulation thermal insulation exterior wall with embedded thermal break bridge. Background Technology

[0002] The prefabricated reverse-insulation exterior wall consists of exterior wall panels and insulation panels. The insulation panels are located on the exterior surface of the exterior wall panels and are an integrated structure with them. The curtain wall is installed on the prefabricated reverse-insulation exterior wall via curtain wall keel adapters and curtain wall embedded parts. To meet the ultra-low energy consumption requirement that the outer insulation layer of the prefabricated reverse-insulation exterior wall should be continuous and intact, the welded plate of the curtain wall embedded parts is extended to the outer side of the prefabricated reverse-insulation exterior wall.

[0003] Please see the appendix Figure 1 and attached Figure 2 The conventional construction procedure for the curtain wall embedded parts with pre-embedded thermal break bridges in the prefabricated insulated exterior wall is as follows: After the curtain wall embedded part 1 is manufactured, it is prefabricated together with the exterior wall panel 2 of the prefabricated insulated exterior wall in the PC processing plant, so that the welding plate 11 of the curtain wall embedded part 1 is extended to the outside of the exterior wall panel 2 of the prefabricated insulated exterior wall. The exterior wall panel 2 of the prefabricated insulated exterior wall is then installed on site. Then the curtain wall keel adapter 3 is welded to the welding plate 11.

[0004] Because the size of the welding plate 11 is larger than that of the curtain wall keel adapter 3, and the insulation board 4 is hollowed out at the pre-embedded position of the welding plate 11, after installing the curtain wall keel adapter 3, a supplementary insulation board 5 needs to be installed in the gap between the curtain wall keel adapter 3 and the insulation board 4 on the welding plate 11. The supplementary insulation board 5 and the insulation board 4 form an integral insulation board structure, which makes the construction of the supplementary insulation board 5 inconvenient. At the same time, the curtain wall keel adapter 3 is a hollow structure, and an insulation board cannot be installed inside, thus failing to meet the ultra-low energy consumption requirement of continuous and complete insulation board on the outside of the external wall panel. This easily leads to thermal bridging at the pre-embedded part of the curtain wall, affecting the insulation performance of the prefabricated insulated exterior wall. Therefore, it is necessary to provide a curtain wall embedded part for pre-embedding thermal bridging in the prefabricated insulated exterior wall, which can solve the problems of inconvenient construction of the supplementary insulation board and the easy occurrence of thermal bridging at the curtain wall embedded part in the existing technology. Summary of the Invention

[0005] The purpose of this utility model is to provide a curtain wall embedded part for prefabricated reverse-insulation thermal bridging of the exterior wall, which can solve the problems of inconvenient construction of post-insulation boards and easy thermal bridging at the curtain wall embedded part in the prior art.

[0006] This utility model is implemented as follows:

[0007] A prefabricated curtain wall embedded component for pre-embedded thermal break bridges in an insulated exterior wall includes a welding plate, anchors, an anchor plate, and a sandwich insulation board. The sandwich insulation board is fixedly connected between the welding plate and the anchor plate. One end of the anchor is fixedly connected to the welding plate, and the anchor penetrates and connects the anchor plate and the sandwich insulation board to form the main body of the curtain wall embedded component. The other end of the anchor is anchored inside the exterior wall panel, so that the anchor plate is pre-embedded on the outside of the exterior wall panel. The sandwich insulation board is matched and filled in the reserved hollow part of the insulation board. The sandwich insulation board and the insulation board form a continuous and complete insulation board structure on the outside of the exterior wall panel. The curtain wall keel adapter is welded to the surface of the welding plate away from the sandwich insulation board.

[0008] The sandwich insulation board has a first through hole for the anchor to pass through, so that the anchor can fit through the sandwich insulation board.

[0009] Both the welding plate and the anchoring plate have a second through hole for the anchor to pass through, so that the anchor can be matched and passed through the anchoring plate and plug-welded through the hole of the anchoring plate. The end of the anchor is inserted into the second through hole of the welding plate and plug-welded through the hole of the welding plate.

[0010] The thickness of the sandwich insulation board is the same as that of the insulation board, the inner side of the sandwich insulation board is flush with the inner side of the insulation board, and the outer side of the sandwich insulation board is flush with the outer side of the insulation board.

[0011] The sandwich insulation board, welding plate, anchoring plate and the reserved hollow parts on the insulation board have the same cross-sectional shape and size, so that the sandwich insulation board matches and fills the reserved hollow parts on the insulation board, and the sandwich insulation board and the insulation board are connected to form a continuous and complete insulation board structure.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] 1. This utility model has a curtain wall embedded main body, with the sandwich insulation board sandwiched between the welding plate and the anchor plate, and matched and filled in the reserved hollow position on the insulation board. It can form a continuous and complete insulation board structure on the outside of the prefabricated reverse-insulated exterior wall panel, thereby meeting the insulation requirements of ultra-low energy consumption and avoiding the generation of thermal bridge phenomenon, thus ensuring the insulation performance of the prefabricated reverse-insulated exterior wall.

[0014] 2. This utility model features a curtain wall embedded main body, with the anchor plate anchored to the outer wall panel via anchors, ensuring the firm and stable anchoring of the entire curtain wall embedded main body. The welding plate is located on the outside of the insulation board and is used to connect the curtain wall keel adapter, placing the curtain wall keel adapter on the outside of the insulation board. This avoids the need for subsequent installation of insulation boards between the curtain wall keel adapter and the pre-reserved hollow positions on the insulation board, simplifying the construction process. While ensuring ultra-low energy consumption insulation performance, it also improves construction efficiency and avoids the thermal bridging phenomenon caused by the inability to fill the hollow structure curtain wall keel adapter with insulation material.

[0015] 3. This utility model has a curtain wall embedded main body, which is anchored to the external wall panel. It can be prefabricated in the factory and directly installed on site. The construction process is simple and easy to operate, the structure is simple, and the cost is low. Attached Figure Description

One end of the anchor 12 is fixedly connected to the welding plate 11, and the anchor 12 passes through and connects the anchor plate 13 and the sandwich insulation board 6 to form the main body of the curtain wall embedded component. The other end of the anchor 12 is anchored in the outer wall panel 2, so that the anchor plate 13 is pre-embedded on the outer side of the outer wall panel 2. The sandwich insulation board 6 is matched and filled in the reserved hollow part of the insulation board 4. The sandwich insulation board 6 and the insulation board 4 form a continuous and complete insulation board structure on the outer side of the outer wall panel 2. The curtain wall keel adapter 3 is welded to the surface of the welding plate 11 away from the sandwich insulation board 6.

[0026] Preferably, the welding plate 11 and the anchor plate 13 can be rectangular plates made of Q235B steel. The anchor plate 13 is hot-dip galvanized with an average dry film thickness of 85μm.
