Description

Technical Field

[0001] The invention relates to the technical field of heat-insulating energy-saving glass curtain wall structures, in particular to a heat-insulating energy-saving glass curtain wall structure. Background Art

[0002] With the development of the construction industry, people's technical requirements for buildings are increasing day by day. Specifically, for building industrial curtain walls, they must have good sturdiness, sound insulation, heat insulation and other functions. The main energy consumption channel of industrial buildings during use is the heat loss of the curtain wall structure. The existing curtain walls require high-altitude work during installation, and the glass curtain walls that are used more are easily damaged during hoisting and transportation. At present, there are also some prefabricated curtain walls that eliminate the potential dangers of workers working at high altitudes, but these prefabricated curtain walls have poor sealing effects, resulting in poor energy-saving, thermal insulation and heat insulation effects of buildings.

[0003] The existing Chinese patent publication number (CN118563966B) discloses a heat-insulating assembled curtain wall, including columns and curtain wall bodies. The curtain wall bodies are slidably arranged on the columns along the length direction of the columns. Two groups of pre-tightening components are arranged on the columns, and each group of pre-tightening components includes a slide plate, a plug rod and two pull ropes. There are multiple slide plates, and multiple slide plates are slidably arranged on the columns along the length direction of the columns. A limit plate is fixedly installed on each slide plate. The plug rod can be clamped with the curtain wall body in the moving direction of the curtain wall body, and each pull rope is fixedly connected to the fixed ends of the multiple plug rods. Two pull ropes are arranged, and the positions of the two pull ropes on the plug rods are matched. The two pull ropes can drive the plug rods to rotate. A limit plate is arranged. The rotation of the plug rods bends the pull ropes between two adjacent plug rods. The bent pull ropes drive the two plug rods to approach each other, and the two adjacent curtain wall bodies clamped with the plug rods can approach each other, so that the contact is tighter, the sealing is higher, and the heat preservation performance is higher.

[0004] However, its structural design is very complicated, and most importantly, this design greatly reduces the traditional advantages of curtain walls, that is, it greatly increases the weight. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in order to overcome the above problems, a heat-insulating energy-saving glass curtain wall structure is provided, which solves the above problems.

[0006] The present invention solves the technical problem by adopting the following technical solutions:

[0007] A heat-insulating energy-saving glass curtain wall structure comprises a double-layer glass curtain wall and a curtain wall aluminum alloy structural frame fixed to the outside of the double-layer glass curtain wall, wherein the double-layer glass curtain wall is provided with two front and rear pieces, and a hollow negative pressure interlayer is formed between the double-layer glass curtain wall and the curtain wall aluminum alloy structural frame to reduce the transfer of heat energy by heat convection, in addition, the curtain wall aluminum alloy structural frame is fixed to a light steel keel outside the wall body by a bolt structure, and a high-sealing heat-insulating curtain wall connector is embedded and fixed between the curtain wall aluminum alloy structural frames to fill gaps and provide auxiliary support and relative fixation to adjacent curtain wall aluminum alloy structural frames.

[0008] In an embodiment of an insulating and energy-saving glass curtain wall structure, the high-sealing insulating curtain wall connector includes a cross-structured hollow aluminum alloy structural frame and a hollow rubber strip fixed on the side of the hollow aluminum alloy structural frame, and the hollow rubber strip is inserted into a card groove on the side of the curtain wall aluminum alloy structural frame.

[0009] In an embodiment of a heat-insulating energy-saving glass curtain wall structure, the hollow aluminum alloy structural frame is pre-filled with rubber adhesive glue, and openings are provided at intervals on the side walls of the hollow aluminum alloy structural frame. When the high-sealing heat-insulating curtain wall connector is installed into the gap between the curtain wall aluminum alloy structural frames, the rubber adhesive glue in the hollow aluminum alloy structural frame is squeezed out.

[0010] In an embodiment of a heat-insulating and energy-saving glass curtain wall structure, rubber strip outlet holes are also spaced apart on the hollow rubber strip for extruding the rubber adhesive glue, and the rubber strip outlet holes and the opening positions on the hollow aluminum alloy structural frame are staggered, so that after the rubber adhesive glue is extruded, the cavity inside the hollow rubber strip is first filled to make it swell, so that it can adapt to the side groove depths of the curtain wall aluminum alloy structural frame of different specifications, and there is no need to select filling pieces of various specifications during installation, which is more convenient. When the hollow rubber strip swells, the excess rubber adhesive glue is squeezed out from the rubber strip outlet holes and filled into the gap between the hollow rubber strip and the side groove of the curtain wall aluminum alloy structural frame to complete a completely fitting seal.

[0011] In an embodiment of a heat-insulating and energy-saving glass curtain wall structure, a plunger cylinder is provided in the middle of the hollow aluminum alloy structural frame, the plunger cylinder is connected to the inner cavity of the hollow aluminum alloy structural frame, and a piston is provided in the plunger cylinder. When the piston is pressed, the rubber bonding glue in the hollow aluminum alloy structural frame can be squeezed out.

[0012] In an embodiment of a heat-insulating and energy-saving glass curtain wall structure, a screw hole is provided at the outer end of the injection plug barrel, and it also includes a bolt threadedly connected to the screw hole. A hexagonal block is fixed at the tail end of the bolt, so that the bolt can be directly installed into the injection plug barrel through an electric drill and then the piston is compressed to complete the extrusion of the rubber adhesive glue.

[0013] In an embodiment of a heat-insulating energy-saving glass curtain wall structure, a pressure plate is fixedly provided on the bolt, and the pressure plate is pressed on the four corners of the curtain wall aluminum alloy structural frame after the bolt is fixedly connected to prevent rainwater from flowing into the screw hole.

[0014] In an embodiment of a heat-insulating and energy-saving glass curtain wall structure, the front and rear end surfaces of the hollow aluminum alloy structural frame are flush with the front and rear end surfaces of the curtain wall aluminum alloy structural frame.

[0015] The advantages and positive effects of the present invention are: firstly, the installation process of the glass curtain wall is simplified, and the installation structure has a higher degree of integration and can achieve a more standardized and unified installation effect;

[0016] In addition, after installation, the filling type installation structure expands the glue or rubber from the inside to the outside, so that the high-sealing heat-insulating curtain wall connector can fit more closely with the curtain wall aluminum alloy structural frame, and the sealing degree is better, which can effectively avoid poor thermal insulation caused by air leakage;

[0017] And because the sealing filling rubber in the present application is located between the curtain wall aluminum alloy structural frames instead of being exposed to the outside of the curtain wall as in the prior art, it is obvious that such a design can effectively prevent the rubber sealing strip from being cracked, broken, shrunk, debonded, etc. due to wind and sun exposure, thereby greatly improving the effective service life after installation;

[0018] Moreover, compared with the above-mentioned patent, the present application is simpler and lighter, and has a lower structural cost. BRIEF DESCRIPTION OF THE DRAWINGS
