Description

Technical Field

[0001] The invention belongs to the technical field of aluminum plate curtain walls, and in particular relates to a glue-free aluminum plate curtain wall structure. Background Art

[0002] The aluminum curtain wall has a unique texture, rich and durable color, and its appearance and shape can be diversified, and it can be perfectly combined with glass curtain wall materials and stone curtain wall materials. Its perfect appearance and excellent quality make it very popular with owners. Its self-weight is light, only one-fifth of marble and one-third of glass curtain wall, which greatly reduces the load of building structure and foundation, and has low maintenance cost and high performance-price ratio. As for the aluminum curtain wall currently used, it is mainly divided into open aluminum plate and glued aluminum curtain wall. The main problem is that after a period of use, the glue joint of the glued aluminum curtain wall is easy to form stains, which flow vertically from the glue joint and are difficult to remove, seriously affecting the use; while the open aluminum curtain wall has a backing metal plate in the inner layer, which increases the cost. On the other hand, since the connection between the aluminum plate and the keel must pass through the backing metal, although waterproof glue is also applied around it, the effect is generally not good, leaving a certain risk of water seepage, so the promotion and use of open aluminum plates is very cautious. Summary of the invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a glue-free aluminum plate curtain wall structure. This aluminum plate curtain wall does not need to be glued, and only uses two waterproof strips to seal and waterproof, with good waterproof effect. No backing metal plate is required in the aluminum plate curtain wall, thereby reducing the cost.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a glue-free aluminum plate curtain wall structure, including an aluminum plate curtain wall and a keel, the keel is used to connect two adjacent aluminum plate curtain walls, the aluminum plate curtain wall has an "L"-shaped presser foot, the keel is provided with a side baffle, a first rubber strip slot and a nose head, a first rubber strip is arranged in the first rubber strip slot, a pressing plate fixes the presser foot between the side baffle and the nose head and makes the first rubber strip be pressed against the keel by the presser foot; the pressing plate is fixed on the nose head; a second rubber strip slot is provided on the pressing plate, a second rubber strip slot is arranged in the second rubber strip slot, and the second rubber strip is pressed against the presser foot by the pressing plate.

[0005] The pressing plate is provided with a first bayonet, and the pressing plate is connected to the cover plate via the first bayonet.

[0006] The pressure plate is provided with symmetrically arranged small baffles, which are clamped on the nose.

[0007] The pressing plate is provided with symmetrically arranged pressing heads, and the pressing plate presses the bottom surface of the pressing foot through the pressing heads.

[0008] The second rubber strip notch is located on the side of the pressing plate, and the second rubber strip is pressed tightly against the side wall of the presser foot.

[0009] The pressing plate is fixed to the nose by screws.

[0010] The cross section of the keel is an axisymmetric structure.

[0011] The keel has an inner cavity.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) The glue-free aluminum plate curtain wall structure of the present invention is waterproofed by using waterproof strips, and no glue is required. Only two waterproof strips are used for sealing and waterproofing, and the waterproof effect is good;

[0014] (2) The glue-free aluminum curtain wall structure of the present invention provides an "L"-shaped pressure foot on the aluminum curtain wall and cooperates with a special keel and a pressure plate.

[0020] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0021] It should be noted that in the description of the present invention, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "up", "down", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention rather than requiring the present invention to be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. The terms "front", "rear", "left", "right", "up", and "down" used in the description of the present invention refer to the directions in the accompanying drawings, and the terms "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, two adjacent aluminum curtain walls 1 are connected by a keel 2, one surface of the keel 2 has side baffles 22 arranged opposite to each other, a nose 24 is arranged at the center of the surface, a first rubber strip notch 23 is arranged on the keel surface between the side baffles 22 and the nose 24, and a first rubber strip 5 is arranged in the first rubber strip notch 23. The edge of the aluminum curtain wall 1 has an "L"-shaped presser foot 11, which is placed between the side baffles 22 and the nose 24, pressed on the first rubber strip 5, and a sealing structure is formed between the keel 2 and the aluminum curtain wall 1. The pressing plate 3 has a symmetrically arranged small baffle 34, and the distance between the two opposite sides of the small baffle 34 is equal to the width of the nose, so that the pressing plate 3 is clamped on the nose through the small baffle 34, which plays a role in positioning and preliminarily fixing the pressing plate; the pressing plate 3 has a symmetrically arranged pressure head 33, which abuts on the bottom surface of the pressure foot 11, and the first rubber strip 5 is pressed tightly on the keel 2 by the pressure foot 11. The pressing plate 3 is fixed on the nose 24 by screws 7. A second rubber strip notch 31 is provided on the side of the pressing plate 3, and a second rubber strip 6 is provided in the second rubber strip notch 31. The second rubber strip 6 is pressed by the pressing plate 3 against the side wall of the presser foot 11 to form a sealing structure between the pressing plate 3 and the presser foot 11. The present invention uses a waterproof rubber strip for waterproofing, does not require gluing, and only uses two waterproof rubber strips for sealing and waterproofing, which has a good waterproof effect, and at the same time avoids the problem that the glue seam formed by gluing is prone to stains flowing, which is difficult to remove and affects the appearance.

[0023] The pressing plate 3 is also provided with a first bayonet 32, and the cover plate 4 is provided with a first clamping piece matched with the first bayonet 32. The first bayonet 32 ​​and the first clamping piece are matched to connect the pressing plate 3 with the cover plate 4. The cover plate 4 seals the screw 7 to prevent rainwater from directly impacting the screw 7, causing the screw to rust and the connection to fail. At the same time, the cover plate 4 can play a decorative role, making the entire aluminum curtain wall more beautiful. The keel 2 has an inner cavity 21. On the one hand, this structure can reduce the weight of the keel 2, and on the other hand, the keel 2 has a higher structural strength. The cross section of the keel 2 is an axisymmetric structure, so that the keel 2 is more evenly stressed. The present invention arranges an "L"-shaped presser foot on the aluminum curtain wall and cooperates with a special keel and a pressing plate. The overall structure is reasonably stressed, the construction operation space is large, the installation is simple and quick, and there is no need to arrange a backing metal plate in the aluminum curtain wall, thereby reducing the project cost.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
