Description

Technical Field

[0001] This utility model belongs to the field of glass curtain wall technology, and specifically relates to a glass curtain wall. Background Technology

[0002] A glass curtain wall consists of glass panels and an aluminum alloy frame. During the installation of a glass curtain wall, columns and beams need to be fixed to the building first. Multiple installation spaces are formed between the columns and beams. Glass panels are then fixed to each installation space, and the glass curtain wall construction is completed.

[0003] Glass curtain walls include exposed frame glass curtain walls and concealed frame glass curtain walls. In exposed frame glass curtain walls, the metal frame is exposed on the outside, while in concealed frame glass curtain walls, the metal frame is located on the inside of the glass panels. During the construction of concealed frame glass curtain walls, the glass panels are first bonded to the aluminum frame using structural adhesive, and then the aluminum frame is fixed to the columns and beams.

[0004] The structural adhesive of a frameless glass curtain wall needs to bear the weight of the glass panel, wind load, and seismic load. During long-term use, the structural adhesive will age, causing changes in its molecular structure, making it unable to effectively transfer the load of the glass panel, which in turn will lead to the glass panel loosening and falling off. Utility Model Content

[0005] This utility model provides a glass curtain wall that aims to solve the problem that glass panels are prone to loosening and falling off when the structural adhesive ages in the existing frameless glass curtain wall.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0032] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] Please refer to the following: Figures 1 to 6The present invention provides a glass curtain wall. The glass curtain wall includes several columns, several beams, and several glass panel assemblies. The columns and beams are crisscrossed, forming installation spaces between adjacent columns and beams for installing glass panel assemblies. Each glass panel assembly includes a glass panel body 1 and an aluminum frame 2. One side of the aluminum frame 2 is an adhesive side, and the other side is a connecting side. The glass panel body 1 is adhesively bonded to the adhesive side of the aluminum frame 2. The connecting side of the aluminum frame 2 has a connecting structure, through which the aluminum frame 2 is fixed to the columns and beams. Supporting structures 3 are provided around the glass panel body 1 on all sides of the aluminum frame 2, and the supporting structures 3 are used to abut against the perimeter of the glass panel body 1. A joint 11 is formed between adjacent glass panel bodies 1, and the joint 11 between adjacent glass panels is filled with sealant.

[0034] The glass curtain wall provided by this utility model, compared with the prior art, provides secondary protection for the glass panel body 1 when the glass panel body 1 is bonded to the aluminum frame 2. The support structure 3 on the aluminum frame 2 is used to press against the glass panel body 1 around its perimeter. When the structural adhesive ages, the support structure 3 on the aluminum frame 2 can support the glass panel body 1, reducing the possibility of the glass panel body 1 loosening or falling off, thereby reducing safety hazards.

[0035] It should be noted that the joints 11 between adjacent glass panel bodies 1 are filled with sealant, which can ensure the airtightness of the glass curtain wall, reduce the penetration of rainwater, air and other substances, and at the same time play a role in heat preservation, heat insulation and sound insulation.

[0036] In some embodiments, such as Figures 1 to 6 As shown, the support structure 3 includes several baffles 31, one side of which can contact the side wall of the glass panel body 1; each baffle 31 is fixedly provided with a limiting plate 32, which is fixedly connected to the aluminum frame 2.

[0037] It should be noted that by fixing several baffles 31 on the aluminum frame 2, the glass panel body 1 can be circumferentially limited; when the glass panel body 1 is bonded to the aluminum frame 2, the bonding position of the glass panel body 1 can be limited. By pressing the several baffles 31 against the perimeter of the glass panel body 1, a secondary fixing effect can be achieved, thereby improving the connection between the glass panel body 1 and the aluminum frame 2; through the above-mentioned arrangement of this application, the stability of the glass panel body 1 on the aluminum frame 2 can be increased, and the displacement of the glass panel body 1 on the aluminum frame 2 can be reduced.

[0038] In some embodiments, such as Figures 1 to 6As shown, the aluminum frame 2 has a groove 21, and the side wall of the aluminum frame 2 has a slide 22 that communicates with the groove 21. The width of the slide 22 is smaller than the width of the groove 21. The limiting plate 32 is located inside the groove 21, and the baffle 31 extends out of the aluminum frame 2 from the slide 22. The limiting plate 32 and the aluminum frame 2 have through holes that are aligned with each other. The limiting plate 32 and the aluminum frame 2 are fixed by bolts and nuts. The baffle 31 is located in the middle of the limiting plate 32, and the two sides of the limiting plate 32 contact the corresponding side wall of the groove 21 to centrally limit the baffle 31.

[0039] It should be noted that the width of the slide 22 is smaller than the width of the slide groove 21. Therefore, by having the two sides of the limiting plate 32 contact the two sides of the slide groove 21, the limiting plate 32 can be limited within the slide groove 21 and the sliding direction can be restricted. After the limiting plate 32 slides into place, it is fixed by bolts and nuts. After the limiting plate 32 is fixed to the aluminum frame 2 by bolts and nuts, the position of the baffle 31 can be fixed so that the baffle 31 contacts the side of the glass panel body 1.

[0040] In some embodiments, such as Figures 1 to 6 As shown, the length of the baffle 31 is less than the thickness of the glass panel body 1. When the joint 11 is filled with sealant, the baffle 31 is located inside the sealant.

[0041] It should be noted that the above settings can ensure that the sealant can completely fill the joint 11, and at the same time, it can also play a certain protective role for the baffle 31, preventing the baffle 31 from being damaged by external environmental factors and extending the service life of the baffle 31.

[0042] In some embodiments, such as Figures 1 to 6 As shown, the aluminum frame 2 is provided with abutment plates 33 on both sides perpendicular to each other on the glass panel body 1. The baffle 31 on the side corresponding to the abutment plate 33 has a slot 311 that is inserted and engaged with the abutment plate 33. The baffle 31 has a threaded hole, and a set screw 34 is provided in the threaded hole. One end of the set screw 34 can press against the abutment plate 33 so that the abutment plate 33 presses against the side of the glass panel body 1.

[0043] It should be noted that the aluminum frame 2 is equipped with a retaining plate 33, and the slot 311 on the baffle 31 is inserted into the retaining plate 33. This structure increases the connection stability between the baffle 31 and the aluminum frame 2. The design of the top screw 34 can make the retaining plate 33 press against the side of the glass panel body 1, further enhancing the fixing effect of the glass panel body 1 on the aluminum frame 2 and improving the safety and reliability of the curtain wall.

[0044] In some embodiments, such as Figures 1 to 6As shown, when the set screw 34 is pressed against the clamping plate 33, a sealing plate (not shown in the figure) is adhered to the baffle 31 at the position of the set screw 34 to seal the set screw 34.

[0045] It should be noted that, through the above settings, after the set screw 34 is tightened against the clamping plate 33, the sealing plate can be glued to the baffle 31 to protect the set screw 34. When the sealant is applied in the joint 11, it can prevent the sealant from sticking to the set screw 34.

[0046] In some embodiments, such as Figures 1 to 6 As shown, the connection structure includes several connecting rods, all of which are located on the connecting side of the aluminum frame 2. Each connecting rod is fixedly connected to the aluminum frame 2, and the columns and beams have through holes for the connecting rods to pass through. The connecting rods have external threads. After the connecting rod passes through the column or beam, the protruding end of the connecting rod is threaded with a nut.

[0047] It should be noted that the aluminum frame 2 is connected to the beams and columns via connecting rods, which can improve the stability between the aluminum frame 2 and the beams and columns, thereby improving the connection strength of the glass curtain wall. During installation, the connecting rods corresponding to the columns pass through the columns, and the connecting rods corresponding to the beams pass through the beams. The protruding ends of the connecting rods are fixed with nuts. Through the above settings, the aluminum frame 2 can be fixed to the beams and columns.

[0048] In some embodiments, such as Figures 1 to 6 As shown, the column is equipped with a mounting bracket, and some of the crossbeams are also equipped with mounting brackets. The mounting brackets are used to fix the column to the building. There is an installation space between the column and the building wall. After the connecting rod passes through the column, the protruding end of the connecting rod is threaded with the nut.

[0049] It should be noted that the explanation takes the mounting bracket on the column as an example; the column is fixed to the surface of the building by the mounting bracket, and an installation space is formed between the column and the building surface, which facilitates the connection rod on the aluminum frame 2 to pass through the column, and the protruding end of the connection rod is fixed by bolts. A mounting bracket is also fixed on the crossbeam corresponding to the building surface, forming an installation space between the crossbeam and the building surface. After the connection rod on the aluminum frame 2 passes through the crossbeam, it can be fixed by nuts. With the above-described configuration, the aluminum frame 2 can be fixed to the crossbeam and the column.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
