[0001] The utility model relates to the technical field of curtain walls, in particular to a curtain wall structure with both bolts and self-tapping screws. Background Art
[0002] Curtain wall is the outer wall of the building, which is non-load-bearing and is hung 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, and can have a certain displacement ability relative to the main structure or a certain deformation ability itself, and is an external protective structure or decorative structure of the building that does not bear the effects of the main structure (the external wall frame support system is also a type of curtain wall system).
[0003] In the existing technology, the panels in the curtain wall are usually glass, and the glass is clamped by a supporting structure system. The supporting structure system includes a beam located on the indoor side of the glass and a pressure plate located on the outdoor side of the glass. When connecting the beam and the pressure plate, one end of the self-tapping screw is usually passed through the pressure plate and the glass and then screwed onto the beam.
[0004] The above-mentioned prior art solutions have the following defects: since the crossbeam is basically made of aluminum alloy material with high hardness, and no threaded holes are reserved on the crossbeam, when the crossbeam and the pressure plate are used to press the glass, on the one hand, it is difficult to screw the self-tapping screw into the crossbeam made of the alloy material, which is time-consuming and laborious. Even if the self-tapping screw is screwed into the crossbeam, it is easy to loosen later, and the stability of the connection is poor; on the other hand, the connection method can only use screw fasteners with drilling effect, the connection method is single and the practicality is low. Utility Model Content

At the same time, they can also be connected with bolts, with multiple connection methods, strong practicality, and certain economic promotion value.
[0006] The above utility model object of the utility model is achieved through the following technical solutions:
[0007] A curtain wall structure with both bolts and self-tapping screws, comprising fasteners, a pressure plate, glass and a crossbeam, wherein the pressure plate and the crossbeam are respectively installed on both sides of the glass, the fastener is used to connect the pressure plate and the crossbeam together and fix them on the glass, a thread groove matching the fastener is provided on a side wall of the crossbeam close to the glass, and an inner wall of the thread groove is provided with an internal thread.
[0008] As a further technical solution of the utility model: a limiting groove is provided on the crossbeam, and the limiting groove is located at one end of the thread groove close to the glass.
[0009] As a further technical solution of the utility model: the fastener is a self-tapping screw, one end of which passes through the pressure plate and the glass and is threadedly connected in the thread groove of the beam, and the external thread of the self-tapping screw matches the internal thread of the thread groove.
[0010] As a further technical solution of the utility model: the fastener is a bolt, the head of one end of the bolt is embedded in the limiting groove, and the other end passes through the glass and the pressure plate and is threadedly connected with a nut.
[0011] As a further technical solution of the utility model: a cover plate is detachably fixed on a side of the pressing plate away from the glass.
[0012] As a further technical solution of the utility model: an external sealing strip is installed on one side of the pressing plate close to the glass.
[0013] As a further technical solution of the utility model: an inner sealing strip is installed on a side of the cross beam close to the glass.

[0023] Embodiment 1:
[0024] Reference Figure 1 , which is a curtain wall structure with both bolts and self-tapping screws disclosed by the utility model, including fasteners, a pressure plate 1, a glass 2 and a crossbeam 3. The pressure plate 1 and the crossbeam 3 are respectively installed on both sides of the glass 2. The fastener is used to connect the pressure plate 1 and the crossbeam 3 together and fix them on the glass 2. A threaded groove 31 matching the fastener is opened on one side wall of the crossbeam 3 close to the glass 2, and an internal thread 32 is opened on the inner wall of the threaded groove 31.
[0025] The fastener is a self-tapping screw 4. One end of the self-tapping screw 4 passes through the pressure plate 1 and the glass 2 and is threadedly connected in the thread groove 31 of the crossbeam 3. The external thread of the self-tapping screw 4 matches the internal thread 32. In this embodiment, ST4.8 self-tapping screws are used for fastening, so that the glass 2 is firmly connected to the pressure plate 1 (outdoor) and the crossbeam 3 (indoor) without looseness.
[0026] A cover plate 11 is detachably fixed to the side of the pressing plate 1 away from the glass 2. An outer sealing strip 12 is installed on the side of the pressing plate 1 close to the glass 2. In this embodiment, outer sealing strips 12 are provided on both upper and lower sides of one end of the fastener. One end of the outer sealing strip 12 is embedded in the mounting groove of the pressing plate 1, and the other end abuts against the glass 2. The outer sealing strip 12 is elastic, which effectively prevents the glass 2 from being crushed by the pressing plate 1. An inner sealing strip 34 is installed on the side of the crossbeam 3 close to the glass 2. In this embodiment, inner sealing strips 34 are provided on both upper and lower sides of the other end of the fastener. One end of the inner sealing strip 34 is embedded in the mounting groove of the crossbeam 3, and the other end abuts against the glass 2. The inner sealing strip 34 is elastic, which effectively prevents the glass 2 from being crushed by the crossbeam 3. In this embodiment, an angle code 35 is fixed inside the crossbeam 3.
[0027] Reference Figure 2 , a limiting groove 33 is provided on the crossbeam 3, and the limiting groove 33 is located at one end of the thread groove 31 close to the glass 2. Further, when the fastener is a bolt 5, the head 51 of one end of the bolt 5 is embedded in the limiting groove 33, and the other end passes through the glass 2 and the pressing plate 1 and is threadedly connected with the nut 52. In this embodiment, the bolt 5 is an M5 bolt, so that the glass 2 and the pressing plate 1 (outdoor) and the crossbeam 3 (indoor) are connected and fixed tightly without looseness.
[0028] The implementation principle of the utility model is as follows: the utility model discloses a curtain wall structure with bolts and self-tapping screws. The thread groove 31 with internal thread 32 and matching with the fastener is pre-opened on the cross beam 3. On the one hand, the screw can be easily screwed into the cross beam 3 when connecting the pressure plate 1 and the cross beam 3 on both sides of the glass 2, which increases the stability of the connection between the cross beam 3 and the pressure plate 1 on both sides of the glass 2, saves time and labor, and improves the efficiency of assembly. At the same time, the thread groove 31 also provides the function of positioning and installation. On the other hand, a limit groove 33 is opened on the cross beam 3, so that the pressure plate 1 and the cross beam 3 can also be connected with bolts 5. There are multiple connection methods, strong practicality, and certain economic promotion value.
[0029] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
