Description

Technical Field

[0001] The utility model relates to the technical field of building connection components, in particular to a decorative connection device for expansion joints of building facades. Background Art

[0002] A building expansion joint is a structural joint set vertically at an appropriate position along the length of the building to prevent cracks or damage to the structure due to climate and temperature changes, such as thermal expansion and contraction. An expansion joint divides building components above the foundation, such as walls, floors, and roofs (except wooden roofs), into two independent parts, allowing the building to expand and contract horizontally along the length.

[0003] In recent years, modern buildings have attached more and more importance to the aesthetics of appearance. Building expansion joints have evolved from traditional rubber strip expansion joints into many types, among which metal spray expansion joints are favored by many architects for their aesthetics. However, metal expansion joints have their disadvantages, that is, the expansion amount is not enough and it is easy to fall off, and the outer gusset plate of the aluminum profile needs to be molded according to different expansion joint sizes, which makes it difficult to adapt to the expansion joint, and difficult to repair, maintain and replace. The vertical aluminum alloy expansion joint decorative connection device generally uses aluminum alloy profiles, which has no expansion amount or very small expansion amount, and is easy to fall off, affecting the use function and the appearance of the exterior wall. And according to the actual size of the expansion joint, the aluminum profile needs to be customized and molded, which increases the material cost and is not easy to repair and replace.

[0004] The patent document with announcement number CN101769012A provides a curtain wall panel expansion joint connection device, which has main panels and auxiliary panels for external decoration fixedly connected to the building curtain walls on both sides, and an expansion panel is arranged between the main panels (aluminum profile pressure plates) on both sides through a connecting component. Although it increases the decorative effect, the decorative panel composed of the main panel, auxiliary panel and expansion panel has a complex structure. When the expansion joint of the building changes, the main panel, auxiliary panel and expansion panel are staggered with each other, which will still cause a large uneven effect on the surface of the decorative panel, affecting the decorative effect of the building.

When disassembling, first remove the aluminum profile buckle edge 10, and then you can reverse the above installation process. It is easy to operate. When the building facade expansion joint shrinks and narrows in the horizontal direction, the aluminum profile pressure plates 2 on both sides move closer to the middle, and the distance between them decreases. At the same time, the adjustment pins 8 on both sides are driven to slide toward the middle along the long holes of the adjustment plate. At this time, the bending degree of the waterproof rubber plate 11 increases, and the decorative panel 1 remains in place. As the building facades on both sides shrink toward the middle, the extruded rubber strips 7 on both sides of the decorative panel slide slightly along the building facade; Figure 7 As shown, when the expansion joint of the building facade stretches and widens in the horizontal direction, the aluminum profile pressure plates 2 on both sides separate outwards, and the distance between them increases, and at the same time, the adjustment pins 8 on both sides slide outwards along the long holes of the adjustment plates. At this time, the bending degree of the waterproof rubber plate 11 decreases, and the decorative panel 1 remains in place. As the building facades on both sides separate outwards, the extruded rubber strips 7 on both sides of the decorative panel slide slightly along the building facade. The decorative panel 1 always maintains the same position when the expansion joint changes, which greatly increases the decorative effect.

[0021] In summary, the purpose of the utility model is achieved.
