Description

Technical Field

[0001] This utility model relates to the technical field of glass curtain wall accessories, and in particular to a glass curtain wall clamp. Background Technology

[0002] As the application of point-supported glass curtain walls becomes increasingly mature, the use of clamps on curtain walls is also becoming more widespread, and the diversification of modern curtain wall architecture is gradually gaining popularity. Existing clamps used in curved curtain walls fall into two categories: firstly, each stiffener can be adjusted independently, but the force is very small, and the stiffeners are prone to slipping, which cannot meet the requirements of modern curtain wall structures; secondly, the stiffeners bear increased force, but the stiffeners cannot be adjusted individually, making installation inconvenient. Therefore, it is necessary to design a glass curtain wall clamp that is multi-angle adjustable, easy to install, and has greater force capacity to address these shortcomings. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a glass curtain wall clamp.

[0004] The present invention adopts the following technical solution:

[0005] A glass curtain wall clamp includes a rear pressure cover, an inner pressure ring, an outer pressure ring, and a stiffening plate. The rear pressure cover has an abutment surface, and the inner and outer pressure rings are fixedly disposed on the abutment surface, with the inner and outer pressure rings being coaxially arranged. The radius of the inner pressure ring is smaller than that of the outer pressure ring, and an annular groove is formed between the outer wall of the inner pressure ring and the inner wall of the outer pressure ring. A connecting block is provided at the bottom of the stiffening plate, and the connecting block is slidably accommodated in the annular groove, allowing the stiffening plate to rotate around the axis of the annular groove.

[0006] Preferably, the connecting block has an arc-shaped cross-section and has an inner side facing the inner pressure ring and an outer side facing the outer pressure ring. The contour of the inner side matches the contour of the outer wall of the inner pressure ring, and the contour of the outer side matches the contour of the inner wall of the outer pressure ring.

[0007] Preferably, the inner side is recessed with a first guide groove, and the outer wall of the inner pressure ring is protruded with a first guide strip that matches the first guide groove.

[0008] Preferably, the outer surface is recessed with a second guide groove, and the inner wall of the outer pressure ring is protruded with a second guide strip that matches the second guide groove.

[0009] Preferably, it also includes a fastener; the connecting block is provided with a vertically extending internal threaded hole; the fastener is screwed into the internal threaded hole, and one end abuts against the abutment surface to lock the connecting block.

[0010] Preferably, the stiffener is fixed at the middle position of the top of the connecting block.

[0011] Preferably, there are two internal threaded holes and two fasteners, and the internal threaded holes are symmetrically arranged on both sides of the stiffener.

[0012] Preferably, the abutting surface is recessed with an annular groove, and one end of the fastener extends into and abuts against the bottom surface of the groove.

[0013] Preferably, the radial width of the groove is greater than the width of the connecting block, the connecting block is disposed in the groove, and the bottom surface of the connecting block is in contact with the bottom surface of the groove.

[0014] Preferably, the end of the rear pressure cap away from the contact surface is fixedly provided with a connecting threaded post.

[0015] The beneficial effects of this utility model are as follows:

[0016] The glass curtain wall clamp of this utility model includes a rear pressure cover, an inner pressure ring, an outer pressure ring, and stiffeners. The inner and outer pressure rings are coaxially arranged and form a circular groove between them. A connecting block is integrally provided at the bottom of the stiffener.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In the description of this utility model, it should be noted that the terms "vertical direction," "up," "down," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] like Figures 1 to 6 As shown, the glass curtain wall clamp of the first embodiment of this utility model includes a rear pressure cover 10, an inner pressure ring 20, an outer pressure ring 30, and a stiffener 40. The rear pressure cover 10 has a flat abutment surface 11. The inner pressure ring 20 and the outer pressure ring 30 are coaxially fixed on the abutment surface 11 by welding or bolting, wherein the radius of the inner pressure ring 20 is smaller than the radius of the outer pressure ring 30, thereby forming a circular groove therebetween. The bottom of the stiffener 40 is provided with a connecting block 50, which is slidably accommodated in this circular groove. The operator can adjust the stiffener 40 steplessly by rotating the connecting block 50 along the trajectory of the circular groove according to the actual installation angle of the glass, realizing the individual adjustment of the angle of a single stiffener 40, thus enhancing the adaptability to irregular glass curtain wall facades or installation error conditions. It should be noted that the inner pressure ring 20 and the outer pressure ring 30 have the function of preventing the connecting block 50 from detaching, so the connecting block 50 and the stiffening plate 40 will not detach from the rear pressure cover 10.

[0039] Specifically, the cross-section of the connecting block 50 is preferably arc-shaped, and the connecting block 50 has an inner side surface 50a and an outer side surface 50b facing the inner pressure ring 20 and the outer pressure ring 30, respectively. The contour of the inner side surface 50a matches the contour of the outer wall of the inner pressure ring 20, and the contour of the outer side surface 50b matches the contour of the inner wall of the outer pressure ring 30, which ensures the smooth and stable sliding of the connecting block 50 in the annular groove. Furthermore, a first guide groove 51 is recessed on the inner side 50a of the connecting block 50, and a first guide strip 21 that slides and engages with it is protruded on the outer wall of the inner pressure ring 20; similarly, a second guide groove 52 is recessed on the outer side 50b of the connecting block 50, and a second guide strip 31 is protruded on the inner wall of the outer pressure ring 30; through the above-mentioned engagement structure, the axial and radial movement and swaying of the connecting block 50 during the sliding process can be effectively restricted, ensuring that the movement trajectory of the stiffener 40 relative to the rear pressure cover 10 is accurate, while the glass load is more evenly transferred to the inner pressure ring 20 and the outer pressure ring 30, thereby enhancing the rigidity and reliability of the overall structure.

[0040] Specifically, the glass curtain wall clamp of this utility model also includes a fastener 60. In this embodiment, the fastener 60 is specifically a set screw, and a vertically extending internal threaded hole 53 is provided on the connecting block 50. After the fastener 60 is screwed into the hole, its lower end can tightly abut against the abutment surface 11 of the rear pressure cover 10, and cooperate with the inner pressure ring 20 and the outer pressure ring 30 to press the connecting block 50, thereby locking the connecting block 50. Among them, the stiffener 40 is fixed at the middle position of the top of the connecting block 50 to ensure that the force is transmitted through the center of the connecting block 50 and avoid generating eccentric torque. Furthermore, there are two internal threaded holes 53 and two fasteners 60, which are symmetrically distributed on both sides of the stiffener 40 to form a symmetrical two-point locking layout, so as to provide a balanced locking force and effectively prevent the connecting block 50 from warping or deflecting in the annular groove that may be caused by single-point locking, making the locking more secure and stable.

[0041] Specifically, the rear pressure cover 10 is fixedly provided with a connecting threaded post 70 at one end away from the abutment surface 11. The connecting threaded post 70 has a threaded structure on its outside, and different accessories can be assembled according to the actual structure used in the project to achieve connection with the main structure of the curtain wall and improve the versatility of the product.

[0042] Specifically, the rear pressure cap 10 has an annular groove 12 recessed on its contact surface 11, and one end of the fastener 60 extends into and abuts against the bottom surface of the groove 12. Figure 4 As shown, in this embodiment, the bottom surface of the connecting block 50 is flat and its height is low. The radial width of the groove 12 is smaller than the width of the connecting block 50. At this time, the connecting block 50 abuts against the upper end of the abutment surface 11, and its bottom surface does not contact the bottom of the groove 12. The main function of the groove 12 is to provide the necessary depth space for the fastener 60 to ensure the reliability of locking.

[0043] It should be noted that, as Figure 7 As shown, this is a glass curtain wall clamp according to the second embodiment of the present invention. The radial width of the groove 12 can also be designed to be greater than the width of the connecting block 50, so that the entire connecting block 50 can be placed in the groove 12, with its bottom surface completely fitting the bottom of the groove, thereby obtaining a larger contact area and better support stability. The groove 12 provides space for the fastener 60 to extend, ensuring that the fastener 60 has sufficient effective locking stroke, thereby ensuring installation strength. On the other hand, the bottom of the groove 12 can serve as an installation reference surface. The height of the groove 12 and the flatness of the bottom can be adjusted according to different sizes and shapes of the connecting block 50 to adapt to different specifications of stiffening plate 40 accessories, enhancing versatility.

[0044] like Figure 1 and Figure 2As shown, in a complete embodiment of the actual application, a front pressure cover 80 is also included. The transmission path of the external loads (such as wind pressure and seismic force) borne by the glass panel is as follows: the load first acts on the glass, then is transmitted to the front pressure cover 80, and then through the front pressure cover 80 to the rear pressure cover 10 (the front pressure cover 80 and the rear pressure cover 10 are usually connected by bolts to bear the force), and finally the rear pressure cover 10 transmits the force to the main structure of the curtain wall.

[0045] Furthermore, in more complex application scenarios, such as for curved glass curtain walls, a ball joint connector 90 can be introduced. The ball joint connector 90 adopts the same connection structure as the stiffening plate 40 to achieve connection with the front cover plate or the rear pressure plate 10. The ball joint connector 90 provides multi-degree-of-freedom rotation, thereby facilitating compensation and adjustment of the glass's planar angle, perfectly meeting the complex spatial positioning requirements of curved curtain walls, and further expanding the application scope of this utility model.

[0046] Compared to existing technologies, the glass curtain wall clamp of this utility model includes a rear pressure cover 10, an inner pressure ring 20, an outer pressure ring 30, and stiffeners 40. The inner pressure ring 20 and the outer pressure ring 30 are coaxially arranged and form an annular groove between them. A connecting block 50 is integrally provided at the bottom of the stiffener 40. The sliding fit between the connecting block 50 and the annular groove allows each stiffener 40 to rotate independently without limit, adjusting its angle to adapt to various glass curtain wall installation angles, thus improving installation flexibility and efficiency. Simultaneously, the connecting block 50 matches the double-sided contours of the inner and outer pressure rings 30 and is locked by fasteners 60, ensuring the installation strength of the stiffeners 40. This ensures that the glass curtain wall clamp has sufficient rigidity and strength when subjected to complex loads, meeting stringent mechanical requirements. Furthermore, the entire glass curtain wall clamp has a compact structure, and the adjustment and locking operations are simple, requiring only conventional tools, significantly simplifying the installation process and reducing construction costs.

[0047] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
