Description

Technical Field

[0001] The invention belongs to the field of expansion and contraction deformation of building exterior envelope structures, and relates to an expansion and contraction structural system of a building exterior envelope structure. Background Art

[0002] As an appendage of the main structure, the external protective structure must be able to adapt to the deformation of the main structure. In the past, the simplest way to deal with it was to close the external protective structure on both sides of the main expansion joint. However, as a high-end decorative system for the building facade, the external protective structure should strive to ensure a unified appearance while meeting the requirements of free expansion and contraction of the building structure.

[0003] At present, the typical expansion and contraction practices of the external enclosure structure in the industry in the past two years have their applicability in their respective fields, but there are also some shortcomings. Such as poor expansion and displacement ability, high processing difficulty, water leakage, and the expansion structure is easily damaged by external forces and fails prematurely and leaks. In addition, the existing typical practices are only for a single external enclosure system, while in actual projects, multiple external enclosure systems often coexist, so higher requirements are placed on the adaptability of the expansion joint structure. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a telescopic structural system of a building exterior envelope structure to solve the problems of adapting to the displacement capacity of the main body, waterproofing and unifying the telescopic structural methods of the exterior envelope structure with multiple systems coexisting.

[0007] Optionally, at least two accordion rubber strips are arranged between the two keels on the inner side of the sealing system.

[0008] Optionally, a heat-insulating layer is provided between the two accordion rubber strips; the heat-insulating layer and the accordion rubber strips are connected with the keels on both sides through an aluminum alloy base.

[0009] Optionally, both sides of the slide rod are connected with aluminum alloy connectors, and the aluminum alloy connectors are fixedly connected to the keel through fasteners.

[0010] Optionally, ball joints are provided at both ends of the sliding rod, and a ball joint slot used in conjunction with the ball joint is provided at one end of the aluminum alloy connecting piece connected to the sliding rod, and the sliding rod is connected to the aluminum alloy connecting piece through the ball joint and the ball joint slot.

[0011] Optionally, the sliding rod is arranged inside the sealing system and is fixedly connected to the aluminum alloy buckle cover through an adjustable stainless steel screw, and the sliding rod is rotatably connected to the adjustable stainless steel screw.

[0012] Optionally, one end of the aluminum single plate is connected with a bent aluminum plate, and the bent aluminum plate is fixed to the keel by a fastener;

[0013] Foam rods and sealants for sealing are arranged between the bent aluminum plate and the keel.

[0014] Optionally, a spacer block or a transition angle steel is provided between the bent aluminum plate and the keel.

The sliding rod 7 is rotatably connected to the adjustable stainless steel screw 5.

[0034] In this embodiment, the aluminum alloy base 12 is fixed to the keel 13 by a stainless steel self-tapping screw 11. A 1 mm thick film 17 is placed between the stainless steel self-tapping screw 11 and the keel 13. The film 17 matches the structure of the aluminum alloy base 12. The connection between the accordion strip 9 on the side of the slide rod 7 and the aluminum alloy base 12 is sealed with a sealant 15. Figure 6 .
