Description
Technical Field
[0001] The utility model relates to the field of glass curtain wall connection structures, in particular to a connection structure capable of moving a glass curtain wall. Background Art
[0002] Glass curtain wall refers to the decorative and functional exterior wall system of the building's facade, usually composed of multi-layer components, including glass, metal, concrete, stone and other materials. Glass curtain wall not only beautifies the appearance of the building, but also has functions such as thermal insulation, waterproofing, sound insulation, and lighting. Glass curtain wall plays an important decorative and functional role in modern buildings and has become a part of the urban landscape.
[0003] The prior art has the following deficiencies: conventional glass curtain walls are usually fixedly installed on the exterior walls of buildings. In order to consider the safety and durability of the glass curtain walls, the glass curtain walls are usually designed to be fixedly connected to the exterior walls of buildings and cannot be disassembled at will. However, for the glass curtain walls of some high-rise office buildings, the glass curtain walls are easily damaged or contaminated with dust during long-term use. In order to replace or clean the glass curtain walls, workers must hang from the top of the high-rise building to the outside of the curtain wall to scrub its surface, or replace the glass curtain wall. Working on the outside of a high-rise building has great safety hazards and is prone to safety accidents such as falling from a building or falling objects from a high altitude.
[0004] Therefore, it is necessary to invent a connection structure that can move the glass curtain wall. Utility Model Content
[0005] To this end, the utility model provides a connecting structure capable of moving a glass curtain wall, wherein the glass curtain wall can slide horizontally along the upper fixing bracket and the lower fixing bracket through the balls on the inner walls of the upper fixing bracket and the lower fixing bracket installed on the outer wall of the building outer wall, and then the upper fixing bracket and the lower fixing bracket capable of rotating into the room are arranged on the two sides closest to the edge of each layer of the building outer wall, so that the glass curtain wall sliding to the two sides of the building outer wall is rotated into the room to complete the replacement or cleaning work, so as to solve the problem that the glass curtain wall is easily damaged or contaminated with dust during long-term use. In order to replace or clean the glass curtain wall, the worker must hang from the top of the high-rise building to the outside of the curtain wall to scrub its surface, or replace the glass curtain wall, and working outside the high-rise building has great potential safety hazards, and is prone to safety accidents such as falling from a building or falling objects from a high altitude.
[0006] To achieve the above object, the present utility model provides the following technical solution: A connection structure capable of moving a glass curtain wall, including a building exterior wall and a glass curtain wall. Between each floor on the inner side of the building exterior wall, there is a partition floor slab. The outer surface of the building exterior wall is divided into uniformly arranged rectangular openings by cement columns or exterior wall steel frames. On the upper side of the rectangular opening on the surface of the building exterior wall, an upper fixing bracket is fixedly installed. On the lower side of the rectangular opening on the surface of the building exterior wall, a lower fixing bracket is fixedly installed.

The upper outer frame bracket can be inserted and fitted on the surface of the upper fixing bracket. The lower outer frame bracket can be inserted and fitted on the surface of the lower fixing bracket. The glass curtain wall is horizontally slidably installed on the surface of the building exterior wall through the upper outer frame bracket and the lower outer frame bracket.
[0007] Preferably, a side bracket is arranged between the upper fixing bracket and the lower fixing bracket. The upper end of the side bracket is fixedly welded to both ends of the bottom surface of the side bracket.

[0009] Preferably, the cross-section of the upper fixing bracket is in a "C" shape, and the cross-section of the upper outer frame bracket is in an inverted "U" shape. At one end of the bottom surface of the inner wall of the upper fixing bracket close to the opening, a steel bar is fixedly installed. After the upper outer frame bracket is inserted into the inner wall of the upper fixing bracket from the top side of the steel bar, it naturally drops under the influence of gravity, so that the steel bar is embedded into the opening at the bottom surface of the upper outer frame bracket.
[0010] Preferably, after the steel bar is embedded into the opening at the bottom surface of the upper outer frame bracket, a rubber plug is inserted into the gap left between the top surface of the upper outer frame bracket and the top surface of the inner wall of the upper fixing bracket. On the side of the outer wall of the upper outer frame bracket away from the upper fixing bracket, there is a rubber plate. The upper and lower ends of the rubber plate extend to the edge of the glass curtain wall and cover the gap between the glass curtain wall and the upper outer frame bracket. A bolt is inserted into the surface of the rubber plate. The rubber plate is fixedly installed on the outer wall of the upper outer frame bracket through the bolt. The outer end of the rubber plug is fixedly connected to the rubber plate.
[0011] Preferably, the cross-section of the lower fixing bracket is in a "C" shape, and the cross-section of the lower outer frame bracket is in an inverted "U" shape. At one end of the bottom surface of the inner wall of the lower fixing bracket close to the opening, a steel bar is fixedly installed. After the lower outer frame bracket is inserted into the inner wall of the lower fixing bracket from the top side of the steel bar, it naturally drops under the influence of gravity, so that the steel bar is embedded into the opening at the bottom surface of the lower outer frame bracket.
[0012] Preferably, the cross-section of the steel bar is an inverted "U" shape. A number of openings are provided on the top surface of the steel bar, and a number of balls are provided on the inner wall of the steel bar.

The upper outer frame bracket or the lower outer frame bracket can slide along the upper fixed bracket or the lower fixed bracket through the balls.
[0013] Preferably, the openings of the rectangular openings on both sides of each floor of the building exterior wall that are closest to the edge are larger. The upper fixed bracket and the lower fixed bracket on the outer side of the rectangular opening on one side of the building exterior wall are not fixedly connected to the building exterior wall. A rotating shaft is fixedly installed inside the lower fixed bracket that is not connected to the building exterior wall. The lower fixed bracket that is not connected to the building exterior wall is rotatably connected to the bottom surface of the inner wall of the rectangular opening of the building exterior wall through the rotating shaft. The inner side of the upper fixed bracket that is not connected to the building exterior wall is fixedly connected to a rotating rod bracket, and the other end of the rotating rod bracket is fixedly connected to the floor of the intermediate layer.
[0014] The beneficial effects of the present utility model are as follows: Through the balls on the inner walls of the upper fixed bracket and the lower fixed bracket installed on the outer wall of the building exterior wall, the glass curtain wall can slide horizontally along the upper fixed bracket and the lower fixed bracket. Then, by providing the upper fixed bracket and the lower fixed bracket that can rotate into the room on both sides of each floor of the building exterior wall that are closest to the edge, the glass curtain wall that has slid to both sides of the building exterior wall is rotated into the room to complete the replacement or cleaning work, so as to achieve the effect that workers do not need to be suspended outside the curtain wall for replacement or cleaning work, and reduce the occurrence of safety accidents such as falling from a building or falling objects from a height.
