Description

Technical Field

[0001] The invention relates to the technical field of aluminum single plate curtain wall connection devices, in particular to a fixing device for curtain walls. Background Art

[0002] Curtain wall is the outer wall of a building. It is non-load-bearing and is hung up like a curtain, so it is also called "curtain wall". It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. It is composed of panels and supporting structure systems. It can have a certain displacement ability relative to the main structure or a certain deformation ability itself. It does not bear the force of the main structure. It acts as a building's external protective structure or decorative structure.

[0003] The existing aluminum veneer side walls are provided with angle brackets, which are then fixedly connected to the keel (supporting structure provided on the exterior wall of the building) through the angle brackets. The specific installation methods include riveting, welding and self-tapping screw connection. If the riveting method is adopted, a through hole is opened on the keel in advance, and then the rivet is driven by a riveting device. This method uses two devices, and the firmness of the riveting is related to the quality of the opening and the thickness of the keel. The welding method is to directly weld the angle bracket to the keel. This method is basically carried out manually and cannot fully guarantee the consistency of the quality of manual welding. At the same time, the above two methods are non-detachable methods. If the aluminum veneer is damaged, it is not conducive to replacement. The self-tapping screw passes through the through hole on the angle bracket and is directly connected to the keel thread. This method is suitable for the installation of light-weight and non-vertical aluminum veneers because the self-tapping screw has relatively poor connection stability. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a fixing device for curtain wall, including a first embracing member and a second embracing member, and the first embracing member and the second embracing member are both U-shaped members, and the first embracing member and the second embracing member cooperate to form a square structure and embracing on the keel. The keel is a rod for fixing the aluminum veneer, and the curtain wall can be connected at any position on the keel by adopting the embracing method.

[0005] A connecting piece is provided in the middle of the first embracing piece, and the connecting piece includes a bottom plate, and first bends are provided on both sides of the upper and lower parts of the bottom plate, and a movable block is provided between the first bends on both sides to slide up and down, and a threaded hole is provided in the middle of the movable block. Bolts are used to pass through the angle code provided on the side wall of the aluminum single plate and then cooperate with the threaded hole to achieve fixed connection of the aluminum single plate. At the same time, the movable block that slides up and down can provide a margin for the installation position, which is conducive to the docking of the aluminum single plate.

[0006] Preferably, a buckle is provided at the end of the first embracing member, and a buckle hole is provided at the end of the second embracing member, and the buckle and the buckle hole cooperate with each other, that is, the first embracing member and the second embracing member are fixedly connected by buckling.

[0007] Preferably, a first through hole is provided at the end of the first engaging piece, and a second through hole is provided at the end of the second engaging piece, and after the first engaging piece and the second engaging piece are matched, the first through hole and the second through hole overlap.

[0008] Preferably, the first through hole and the second through hole are interspersed with self-tapping screws, and the apertures of the first through hole and the second through hole are smaller than the outer diameter of the self-tapping screws. Since the first and second engaging parts are only fixed to the keel by being engaged, the weight of the aluminum veneer and external wind forces can easily cause the first and second engaging parts to slide up and down the keel. In severe cases, the first and second engaging parts may be disengaged. Therefore, self-tapping screws are provided to achieve a tight connection with the keel. At the same time, the size matching relationship between the first and second engaging parts and the self-tapping screws also realizes the threaded connection between the self-tapping screws and the first and second engaging parts, thereby improving the stability of the connection.

[0009] Preferably, a second bend is provided above and below the first bend, and the second bend prevents the movable block from falling off. The first bend is used to prevent the movable block from falling off from the front, while the second bend prevents the movable block from falling off from the bottom or top. Due to the bending production setting, in order to improve the structural strength, welding can be performed on both sides of the upper and lower parts of the first bend to prevent the first bend from being deformed by force and releasing the movable block.

[0010] Preferably, a groove is provided on the inner side of the first engaging member, and the bottom plate is welded in the groove, that is, the first engaging member presses the bottom plate onto the keel to improve the stability of the connection.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. Compared with welding and riveting, the present invention can be disassembled and assembled, and if the aluminum single plate is damaged, it is convenient to replace it.

[0013] 2. The self-tapping screws are provided, which not only limit the positions of the first engaging member and the second engaging member on the keel, but also prevent the first engaging member and the second engaging member from being disengaged.

[0014] 3. A movable block is provided to facilitate the docking of the aluminum veneer installation. At the same time, the setting of the first bend can clamp the first bend after the aluminum veneer is installed to prevent deformation and improve the stability of the installation.

[0022] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] like Figures 1 to 4 As shown, a fixing device for curtain wall includes a first embracing member 2 and a second embracing member 4, and the first embracing member 2 and the second embracing member 4 are both U-shaped members, that is, the first embracing member 2 and the second embracing member 4 are formed by bending, and the first embracing member 2 and the second embracing member 4 cooperate to form a square structure and embracing on the keel. This method facilitates the first embracing member 2 and the second embracing member 4 to be fixedly connected to any position of the keel.

[0024] A connecting member 1 is provided in the middle of the first embracing member 2, and the connecting member 1 includes a bottom plate 13, which is a vertically placed plate. Both sides of the upper and lower parts of the bottom plate 13 are bent to provide first bends 11, and a movable block 14 is provided to slide up and down between the first bends 11 on both sides. The first bend 11 is formed by bending, and the first bend 11 prevents the movable block 14 from falling off from the front. Since the first bend 11 is subjected to a straightening force after the aluminum single plate is installed, the first bend 11 is prevented from deforming. Welding treatment can be performed on both sides of the upper and lower parts of the first bend 11 to increase the tensile strength of the first bend 11. A threaded hole 15 is provided in the middle of the movable block 14. When the aluminum single plate is installed, bolts are used to pass through the preset angle code on the side of the aluminum single plate, and then cooperate with the threaded hole 15 to realize the installation of the aluminum single plate. After fixing, a part of the first bend 11 is clamped by the angle code and the movable block 14, which also achieves the effect of preventing the first bend 11 from deforming.

[0025] A fastener 22 is provided at the end of the first engaging member 2, and the front end of the fastener 22 is a wedge-shaped block. A buckle hole 42 is provided at the end of the second engaging member 4. The fastener 22 and the buckle hole 42 cooperate with each other, that is, the wedge-shaped block slides into the buckle hole 42, thereby realizing the connection between the first engaging member 2 and the second engaging member 4.

[0026] A first through hole 21 is provided at the end of the first engaging piece 2, and a second through hole 41 is provided at the end of the second engaging piece 4. After the first engaging piece 2 and the second engaging piece 4 are matched, the first through hole 21 and the second through hole 41 overlap, so as to insert relevant fixing parts to avoid the problem of accidental disengagement of the first engaging piece 2 and the second engaging piece 4.

[0027] The first through hole 21 and the second through hole 41 are interspersed with self-tapping screws 3, which are used to be threadedly connected to the keel, which not only limits the first embracing part 2 and the second embracing part 4 from sliding on the keel, but also prevents the first embracing part 2 and the second embracing part 4 from disengaging. The aperture of the first through hole 21 and the second through hole 41 is smaller than the outer diameter of the self-tapping screw 3. This arrangement can realize that the self-tapping screw 3 can be threadedly connected to the first embracing part 2 and the second embracing part 4, thereby improving the structural strength.

[0028] A second bend 12 is provided above and below the first bend 11, and the second bend 12 prevents the movable block 14 from falling off. That is, the second bend 12 is used to prevent the movable block 14 from sliding out of the bottom plate 13 from the bottom or the top.

[0029] A groove is provided on the inner side of the first embracing member 2, and the bottom plate 13 is welded in the groove, that is, the bottom plate 13 is located between the first embracing member 2 and the keel, so as to improve the stability of the structural connection.

[0030] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
