Description

Technical Field

[0001] The utility model relates to the field of glass curtain walls, and relates to a hidden frame glass curtain wall. Background Art

[0002] A glass curtain wall refers to a building exterior enclosure structure or decorative structure composed of a support structure system and glass, which can have a certain displacement ability relative to the main structure and does not share the actions borne by the main structure. The glass curtain wall includes two types: the exposed frame glass curtain wall and the hidden frame glass curtain wall. Among them, the metal frame of the hidden frame glass curtain wall is hidden behind the glass, and the metal frame is hardly visible outdoors. The installation of the hidden frame glass curtain wall mainly includes three steps. First, directly bond the glass panel to the surface of the aluminum alloy sub-frame with silicone structural adhesive and double-sided tape; second, tightly connect the aluminum alloy sub-frame and the aluminum alloy keel with aluminum alloy pressing blocks and stainless steel bolts; finally, insert a foam strip at the joint of two glass panels and inject silicone building sealant for caulking. Four groups of aluminum alloy pressing blocks are required at the four edges of each glass panel. The aluminum alloy pressing blocks are usually fixed with two stainless steel bolts, which may become loose after long-term use, and then the aluminum alloy pressing blocks cannot play a good protection role.

[0003] In summary, to solve the deficiencies in the prior art, a hidden frame glass curtain wall with a simple structure needs to be designed. Summary of the Utility Model

[0004] The utility model provides a hidden frame glass curtain wall to solve the problems of the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: a hidden frame glass curtain wall includes: an aluminum alloy frame, a glass curtain wall, a U-shaped aluminum alloy pressing block, and a limit clamping member. The glass curtain wall is symmetrically bonded to the aluminum alloy frame. The U-shaped aluminum alloy pressing block is fixed on the aluminum alloy frame and is located between the glass curtain walls. Convex strips are provided on the left and right and front and back sides of the inner groove of the U-shaped aluminum alloy pressing block. The limit clamping member includes a middle block and clamping blocks annularly arranged on the middle block. The width of the clamping blocks is set to be smaller than the width of the groove. Card slots matching the convex strips are provided on both sides of the clamping blocks, and limit plates are provided at the outer ends of the clamping blocks.

[0006] Further improvement, the cross sections of the convex strips and the card slots are semi-circular, and the diameter of the card slots is set to be larger than the diameter of the convex strips.

[0007] Further improvement, guiding surfaces are provided on both sides of the bottom of the clamping blocks and the limit plates.

[0008] Further improvement, the outer end surfaces of the convex strips are located inside the outer end surfaces of the U-shaped aluminum alloy pressing blocks.

[0009] Further improvement, the U-shaped aluminum alloy pressing block is fixed on the aluminum alloy frame by two groups of fastening bolts arranged at intervals.

[0010] Compared with the prior art, the beneficial effects of the hidden-frame glass curtain wall of the present utility model are as follows:

[0011] After installing four groups of glass curtain walls and U-shaped aluminum alloy pressing blocks, place the middle block of the limit clamping part at the center. Since the width of the clamping block is set smaller than the width of the groove, at the same time, press each group of cross-shaped clamping blocks into the inner groove of the corresponding U-shaped aluminum alloy pressing block, so that the convex strip is pressed into the clamping groove of the deformed clamping block, and the limiting plate is located in the inner groove and at the outer end of the convex strip, so that the limit clamping part cannot move left and right or up and down. Through the clamping fit of the convex strip and the clamping groove, each group of independently fixed U-shaped aluminum alloy pressing blocks are combined to form a whole. Even if a single U-shaped aluminum alloy pressing block becomes loose, it can still maintain the fixing effect through the other U-shaped aluminum alloy pressing blocks on both sides. Through this whole, the stability of the press-fitting of the glass curtain wall is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will further elaborate on the technical solution of the present utility model in conjunction with the embodiments and the appended Figures 1 to 4 drawings.

[0020] Embodiment 1

[0021] A hidden-frame glass curtain wall, comprising: an aluminum alloy frame 1, a glass curtain wall 2, a U-shaped aluminum alloy pressing block 3, and a limiting and clamping member 4. The glass curtain wall 2 is symmetrically bonded to the aluminum alloy frame 1. The U-shaped aluminum alloy pressing block 3 is fixed to the aluminum alloy frame 1 and is located between the glass curtain walls 2. Ribs 32 are provided on the left and right, front and back sides of the inner groove 31 of the U-shaped aluminum alloy pressing block 3. The limiting and clamping member 4 includes a middle block 41 and a clamping block 42 that is annularly arranged at 90 degrees around the middle block 41. The width of the clamping block 42 is set to be smaller than the width of the groove 31. Grooves 43 that match the ribs 32 are provided on both sides of the clamping block 42. A limiting plate 44 is provided at the outer end of the clamping block 42.

[0022] As Figures 1 to 4 shown, the working principle of the present utility model is as follows: First, the glass curtain wall 2 is directly bonded to the aluminum alloy frame 1 with silicone structural adhesive and double-sided tape. Then, the U-shaped aluminum alloy pressing block 3 is fixed to the aluminum alloy frame 1 and is located between the glass curtain walls 2. The upper surface of the glass curtain wall 2 is pressed by the flanges on both sides of the U-shaped aluminum alloy pressing block 3. After installing four groups of glass curtain walls 2 and U-shaped aluminum alloy pressing blocks 3, the middle block 41 of the limiting and clamping member 4 is placed at the center. Since the width of the clamping block 42 is set to be smaller than the width of the groove 31, at the same time, each group of cross-shaped clamping blocks 42 is pressed into the inner groove 31 of the corresponding U-shaped aluminum alloy pressing block 3, so that the ribs 32 are pressed into the grooves 43 of the deformed clamping block 42, and the limiting plate 44 is located in the inner groove 31 and is placed at the outer end of the ribs 32, so that the limiting and clamping member 4 cannot move left and right or up and down. Through the clamping cooperation of the ribs 32 and the grooves 43, each independently fixed U-shaped aluminum alloy pressing block 3 is combined to form a whole. Even if a single U-shaped aluminum alloy pressing block 3 becomes loose, the fixing effect can still be maintained by the other U-shaped aluminum alloy pressing blocks 3 on both sides. Through this whole, the stability of the press-fitting of the glass curtain wall 2 is further improved.

[0023] As a further preferred embodiment, the cross-sections of the ribs 32 and the grooves 43 are semi-circular, and the diameter of the groove 43 is set to be larger than the diameter of the rib 32. The semi-circular ribs 32 and grooves 43 can reduce the friction during press-fitting, making the clamping and assembly smoother.

[0024] As a further preferred embodiment, guiding surfaces 45 are provided on both sides of the bottom of the clamping block 42 and the limiting plate 44. The guiding surfaces 45 can reduce the friction during press-fitting, making the clamping and assembly more smooth.

[0025] As a further preferred embodiment, the outer end surface of the rib 32 is located inside the outer end surface of the U-shaped aluminum alloy pressing block 3. Since the clamping groove 43 of the clamping block 42 extends to one side of the middle block 41 and there is a certain distance between the rib 32 and the middle block 41, it can make the part of the clamping groove 43 closest to the middle block 41 less deformed, and thus make it easier for the rib 32 to enter the clamping groove 43.

[0026] As a further preferred embodiment, the U-shaped aluminum alloy pressing block 3 is fixed to the aluminum alloy frame 1 by two groups of fastening bolts 5 arranged at intervals. The U-shaped aluminum alloy pressing block 3 is fixed to the aluminum alloy frame 1 by the two groups of fastening bolts 5.

[0027] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
