Description

Technical Field

[0001] The utility model relates to the field of building curtain walls, in particular to a perforated aluminum plate curtain wall structure. Background Art

[0002] In addition to the conventional transparent glass curtain wall, the building's facade also has a non-transparent curtain wall part. This part of the inter-layer and outdoor extension is usually used to lay out electrical equipment, such as: air conditioning host, fresh air system host, etc. This part of the open or semi-open space also needs to be equipped with a curtain wall to achieve sunshade and meet ventilation requirements. This part of the curtain wall is generally a metal or plastic curtain wall, and the curtain wall is punched or formed with vents, which are generally made into decorative patterns. Metal curtain walls are the most widely used, and their durability and reliability are relatively higher, such as: perforated aluminum curtain walls.

[0003] The structure of the existing perforated aluminum curtain wall is: the aluminum plate assembly is fixed on the frame through the corner code, and the edge of the frame or part of the aluminum plate assembly is directly installed on the outer side of the curtain wall support frame through screws. Among them, a gap of at least 15mm needs to be reserved between the plates of the aluminum plate assembly, and this gap is used to fill the sealant. The disadvantage is that the sealant is relatively wide. Since the outer surface of the sealant is exposed for a long time, this aggravates the dust accumulation efficiency at the glue joint, resulting in rain marks and affecting the appearance. In addition, the amount of sealant used during the construction of this structure is relatively large.

[0004] Another existing aluminum plate curtain wall structure is: the aluminum plate assembly is installed in a frame composed of curtain wall columns and beams, and the aluminum plate is fixed in a plug-in manner, that is, the left and right sides of the plate are plugged into the frame.

[0005] The plug-in aluminum plate has a long plug-in edge and a double-sided fixed structure. Its end face is prone to deformation when subjected to wind load. Once subjected to large wind load for a long time, the end face of the aluminum plate will produce irreversible deformation, which will affect the surface quality and appearance. In addition, this type of aluminum plate is compactly installed, and its subsequent repair and replacement requires the disassembly of multiple aluminum plates, which is very troublesome to maintain.

[0006] Therefore, there is an urgent need for a perforated aluminum plate curtain wall structure that can solve one or more of the above problems. Utility Model Content

[0007] In order to solve one or more problems existing in the prior art, the utility model provides a perforated aluminum plate curtain wall structure. The utility model adopts the following technical solutions to solve the above problems: a perforated aluminum plate curtain wall structure, comprising: a curtain wall panel, a plurality of through grooves are formed on the facade of the curtain wall panel, a transverse folding edge is formed on the upper side or the lower side of the curtain wall panel, a longitudinal folding edge is formed on the left and right sides of the curtain wall panel, and the transverse folding edge is fixed on the crossbeam by an angle bracket;

[0008] The longitudinal connecting member has a connecting step formed on the side facing the column, and a groove formed on the side背离 the column. The longitudinal folding edge is fixedly connected to the connecting step, and a bolt or screw passes through the groove to fix the longitudinal connecting member on the side of the column.

[0009] In some embodiments, the longitudinal folding edge is fixedly connected to the connecting step through a connecting member, and the connecting member is any one of a screw, a bolt and a rivet. The gap formed among the connecting member, the longitudinal folding edge and the column is filled with sealant.

[0010] The beneficial value obtained by the present utility model is that the two longitudinal folding edges and two transverse folding edges of the curtain wall panel are respectively fixed through the longitudinal connecting member and the corner code, realizing the four-side fixation of the curtain wall panel. On the premise of four-side fixation, the length of the longitudinal folding edge can be reduced to save the profile consumption of the aluminum curtain wall panel and shorten the distance between the curtain wall panel and the column. When suffering from wind load, the deformation of the curtain wall panel is smaller and it is easier to restore to a flat state; the structure is relatively more concise than the traditional fixed frame structure, and multiple connecting profiles / components are not required for single-side fixation.

[0017] To make the above - mentioned objects, features and advantages of the present utility model more understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present utility model. However, the present utility model can be implemented in many other ways different from this description. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0018] As Figure 1 shown, the existing fixed structure of the framed aluminum - plate curtain wall is as follows: The folded edge of the curtain - wall board 3 (aluminum plate) is first fixedly connected to the L - shaped member 40 through rivets 41. The b - shaped member 4 is first fixedly connected to the column 1 through screws 42, and then the curtain - wall board 3 loaded with the L - shaped member 40 is connected to the b - shaped member 4, that is, the L - shaped member 40 and the b - shaped member 4 are connected through screws 42, and the gap formed after their connection is filled with a sealant rod and sealant 43. Figure 1 The structure shown uses more components during installation, and it is necessary to pass through the gap for screw fastening and apply a large amount of sealant. The installation and maintenance of such a structure are not only cumbersome but also very consumptive of materials. Especially when replacing the curtain - wall board, it is necessary to remove a large amount of sealant and re - apply a large amount of sealant.

[0019] As Figure 2 shown, the existing plug - in type aluminum - plate curtain - wall structure is as follows: The U - shaped member 44 is fixed on the outer side surface of the column 1 through screws. The folded edges of two adjacent curtain - wall boards 3 are inserted into the U - shaped member 44 and fixed through rivets / screws, and then a sealant rod 45 is arranged at the gap and sealant 43 is applied to prevent the screws from rusting. Figure 2 When disassembling the structure shown, not only a large amount of sealant needs to be removed, but generally the U - shaped member 44 also needs to be disassembled after the sealant is removed (when removing the rivets / screws on one side of the curtain - wall board alone, it is easy to cause unilateral stress on the U - shaped member 44, resulting in deformation or detachment of the U - shaped member 44). Therefore, replacing the curtain - wall board of this plug - in type structure is also very time - consuming and consumptive of materials.

[0020] As Figure 3 shown, the present utility model discloses a perforated aluminum - plate curtain - wall structure, which includes: a curtain - wall board 3. Multiple through - slots 30 are formed on the vertical surface of the curtain - wall board 3. A horizontal folded edge 31 is formed on the upper or lower side of the curtain - wall board 3. Longitudinal folded edges 32 are formed on the left and right sides of the curtain - wall board 3. The horizontal folded edge 31 is fixed on the cross - beam 2 through an angle - code 6 (the angle - code 6 and the horizontal folded edge 31 are fixed on the surface of the cross - beam 2 by screws);

[0021] A longitudinal connector 5 is formed with a connecting step 51 on one side of the longitudinal connector 5 facing the column 1, and a groove 50 is formed on one side of the longitudinal connector 5 facing away from the column. The longitudinal fold 32 is fixedly connected to the connecting step 51, and bolts or screws pass through the groove 50 to fix the longitudinal connector 5 to the side of the column 1.

[0022] It should be noted that in the above structure, the cross beam 2 and the column 1 form a fixed frame of the curtain wall panel 3, the curtain wall panel 3 is a perforated aluminum plate, the through groove 30 is used for ventilation and light transmission, and two adjacent curtain wall panels 3 are separated by the column 1.

[0023] Specifically, combined Figure 3 As shown, the longitudinal fold 32 is fixedly connected to the connecting step 51 through a connecting piece, and the connecting piece is any one of a screw, a bolt and a rivet, and the gap formed between the connecting piece, the longitudinal fold 32 and the column 1 is filled with a sealant 9;

[0024] The cross section of the longitudinal connector 5 is concave-shaped, and a protruding flange 52 is formed on one side of the longitudinal connector 5 forming the connecting step 51, and the flange 52 is connected to the column 1. Since the protruding length of the flange 52 is short, the amount of sealant 9 at the gap is not large, and the purpose of providing the flange 52 is to improve the stability of the structure.

[0025] Two adjacent curtain wall panels can be connected by a plug-in structure, in which case the columns do not serve as the longitudinal edges directly connected in the frame. Figure 4 As shown, the special-shaped connector 8 is provided with a slot 80, and the special-shaped connector 8 is fixedly connected to the column 1 by screws, one end of the L-shaped connector 7 is inserted into the slot 80 (tight fit), and the L-shaped connector 7 will cover the screws between the special-shaped connector 8 and the column 1 after installation; one curtain wall panel 3 is connected to the L-shaped connector 7 by rivets, and the other curtain wall panel 3 is connected to the protruding edge of the special-shaped connector 8 by rivets. Since the fixing screws of the special-shaped connector 8 and the column 1 are located inside and are blocked, it is not necessary to apply sealant between two adjacent curtain wall panels 3 for rust prevention, but this structure still has the problem of inconvenience in later maintenance.

[0026] In summary, the two longitudinal folded edges and two transverse folded edges of the curtain wall panel are fixed by longitudinal connectors and angle brackets respectively, so that the four sides of the curtain wall panel are fixed. Under the premise of four-side fixation, the length of the longitudinal folded edges can be shortened to save the profile usage of the aluminum curtain wall panel and shorten the distance between the curtain wall panel and the column. When subjected to wind load, the curtain wall panel is less deformed and is easier to restore to a straight state. The structure is simpler than the traditional fixed frame structure, and single-side fixation does not require the use of multiple connecting profiles / components.

[0027] The above-described embodiments only express one or more implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the attached claims.
