Description

Technical Field

[0001] This utility model relates to the field of curtain wall connection structure technology. Specifically, it relates to a diagonal connecting rod for curtain walls, which is suitable for curtain wall frame structures without vertical frames, requiring diagonal connections, and with varied spatial shapes, thus meeting the performance and appearance requirements of curtain walls with special shapes. Background Technology

[0002] With the development of the curtain wall industry, the market's requirements for curtain wall performance and design are constantly increasing. This has led to the emergence of curtain wall devices that do not require vertical frames, relying solely on a combination of tie rods and horizontal frames as the main load-bearing structure to achieve the design goals of curtain walls with special shapes. However, the conventional frame curtain wall tie rods currently on the market have a single structural function and cannot adapt to complex and varied shape requirements, especially failing to meet the connection requirements of curtain wall structures with varying angles and spatial configurations. This limits the research and development and application of such special-shaped curtain walls.

[0003] Therefore, there is an urgent need for a connecting device that can be diagonally connected to the horizontal frame, is adjustable, and can be pre-tightened to solve the shortcomings of existing tie rods that cannot be diagonally connected, and meet the market demand for complex-shaped curtain walls. Utility Model Content

[0004] To address the problem that existing frame curtain wall tie rods cannot meet the needs of complex and varied shapes, especially the difficulty in adapting to the connection of curtain wall structures with varying angles and spaces, this utility model provides an oblique connection tie rod for curtain walls, which can realize oblique multi-angle connection and the tie rod can be pre-tightened and adjusted.

[0005] This utility model is achieved through the following technical solution: a diagonal connecting rod for curtain walls, characterized in that: it includes a rod with external threads at both ends; a right-hand threaded locking nut and a right-hand threaded connector are sequentially arranged at one end near the rod, and a left-hand threaded locking nut and a left-hand threaded connector are sequentially arranged at the other end near the rod; the right-hand threaded locking nut and the left-hand threaded locking nut are threadedly fitted onto the rod; the inner side of the right-hand threaded connector and the left-hand threaded connector is provided with a threaded hole A that mates with the thread of the rod, and the outer side of the left-hand threaded connector and the right-hand threaded connector is provided with a threaded hole B; a connecting screw is provided on the outer side of the left-hand threaded connector and the right-hand threaded connector, which is threadedly connected to the threaded hole B; a locking washer and a diagonal washer are sequentially threaded onto the connecting screw.

[0006] Furthermore, the included angle of the inclined washer is 15 to 30 degrees.

[0007] The beneficial effects and features of this utility model are as follows: This invention achieves oblique connection of the tie rod through the cooperation of angled washers, locking washers, and connecting screws, meeting the connection requirements of various complex oblique angles and adapting to curtain wall designs with varying oblique directions and spatial shapes. By utilizing the right-hand threaded connector, right-hand threaded lock nut, left-hand threaded connector, and left-hand threaded lock nut at both ends of the tie rod, preload can be applied during installation, effectively improving the structural stability of the tie rod during installation.

Detailed Implementation

[0011] The following combination Figure 1-3 The contents of this utility model will be described in detail through specific embodiments. Example

[0012] The diagonal connecting rod for curtain walls includes: a rod 1 with external threads at both ends, one end of which is machined with a positive thread and the other end with a reverse left-hand thread; a right-hand threaded locking nut 2 and a right-hand threaded connector 3 are sequentially provided near one end of the rod, and a left-hand threaded locking nut 7 and a left-hand threaded connector 8 are sequentially provided near the other end of the rod; the right-hand threaded locking nut and the left-hand threaded locking nut are threadedly fitted onto the rod; the inner side of the right-hand threaded connector and the left-hand threaded connector is provided with a threaded hole A that mates with the thread of the rod, and the outer side of the left-hand threaded connector and the right-hand threaded connector is provided with a threaded hole B; a connecting rod 6 is provided on the outer side of the left-hand threaded connector and the right-hand threaded connector, and is threadedly connected to the threaded hole B; a locking washer 4 and a bevel washer 5 are sequentially threaded onto the connecting rod.

[0013] Preferably, the included angle of the inclined washer is 15 to 30 degrees.

[0014] Functions of each component: Tie rod 1: The main load-bearing component, which transmits tensile and shear forces between the cross frames; Right-hand threaded connector 3 / Left-hand threaded connector 7: Enables the rotational adaptation between the pull rod and the connecting screw, and transmits preload; Connecting screw 6: Adapts to cross frames of different thicknesses, adjusting the connection distance between the pull rod and the cross frame; 5-inch beveled washer: eliminates the gap between the inclined surface of the cross frame and the connecting screw, achieving an oblique fit; Locking washer 4: Enhances the anti-loosening performance of threaded connections and prevents loosening after long-term use; Right-hand threaded lock nut 2 / Left-hand threaded lock nut 8: Locks the relative position of the connector and the pull rod, applies and maintains preload; Horizontal frame 9: Curtain wall frame load-bearing component.

[0015] Installation process of this utility model: I. Installation Preparation: 1. Fix the inclined threaded rod 6 on the upper and lower horizontal frames 9 where the connecting rod needs to be installed by locking washers 4 and inclined washers 5. Specifically, pass the connecting threaded rod through the horizontal frame through hole 10 of the horizontal frame, and screw the locking washers 4 and inclined washers 5 into the upper and lower ends of the connecting threaded rod, and fix it after locking.

[0016] 2. Tighten the locking nut 2 and the connector 3 onto the pull rod 1, and tighten them to the innermost end, so that the length of the entire assembled pull rod is minimized after assembly.

[0017] II. During installation: Place the assembled tie rod from step 2 of the installation preparation process into the center of the upper and lower horizontal frames as required, aligning it vertically with the connecting screw from step 1. Rotate the connectors 3 at both ends of the tie rod to connect them with the connecting screws 6 at both ends. Adjust the tightness appropriately, and finally lock the tie rod by rotating the locking nut 2 to lock the connectors 3 at both ends, completing the installation of one layer of tie rods. The installation of the next layer of tie rods is the same as the previous layer.
