Description

Technical Field

[0001] This utility model relates to the field of cable-stayed curtain walls, and in particular to a connection node structure between the steel support and the cable of a cable-stayed curtain wall. Background Technology

[0002] Cable-stayed facades are a type of facade system that uses high-strength steel cables as the main support structure. These facades typically consist of vertical and horizontal cables that secure glass panels or other types of sheet metal at their intersections.

[0003] In traditional cable-stayed curtain walls, the size of the pre-drilled holes at the steel support connections must meet the requirements of the construction process while also taking aesthetics into account.

[0004] The diameter of traditional pre-drilled holes is generally 2-3 times the cable diameter. Under load, the cable will swing and rub against the edge of the pre-drilled hole. This can cause the cable to break or snap, or even break, affecting the cable's service life. This needs to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a connection node structure between the steel support and the cable of a cable-stayed curtain wall, which improves the service life of the cable.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a connection node structure between the steel support and the cable of a cable-stayed curtain wall, comprising: A steel support includes a fixed pipe and an installation pipe, wherein the fixed pipe is horizontally arranged and the installation pipe passes through the fixed pipe along the diameter direction of the fixed pipe; A cable extends into the mounting tube, and a lock head is provided at the end of the cable. A locking ring is provided inside the mounting tube for the lock head to pass through, and a nut for pressing the locking ring is threaded onto the lock head. A limiting block is fitted onto the outer wall of the cable and located at the opening of the mounting tube, with a gap between the limiting block and the inner wall of the mounting tube.

[0007] In a preferred embodiment, the present invention can be further configured such that the limiting block includes a pair of clamping blocks, the clamping blocks having a semi-circular cross-section, and the two ends of the pair of clamping blocks are fixed together by embedded screws.

[0008] In a preferred embodiment, the present invention can be further configured such that a locking gap is provided between the end positions of the pair of clamping blocks.

[0009] In a preferred embodiment, the present invention can be further configured such that the aperture of the limiting block is in the shape of a trumpet, expanding outward from the center.

[0010] In a preferred embodiment, the present invention can be further configured such that the two ends of the aperture of the limiting block are provided with inner chamfers.

[0011] In a preferred embodiment, the present invention can be further configured such that the outer wall of the outer end of the limiting block is provided with an outer chamfer.

[0012] In a preferred embodiment, the present invention can be further configured such that a cap is provided at the end of the mounting tube opposite to the limiting block.

[0013] In summary, this utility model has the following beneficial effects: 1. By setting a limiting block between the steel support and the cable, the cable and the reserved hole of the steel support can be isolated. When the cable swings, the cable will not directly contact the steel support. Even if there is a collision or friction, it will not affect the cable, thus avoiding damage to the cable and improving the service life of the cable. 2. By setting interlocking limit blocks, the limit blocks can be easily installed and fixed, increasing the convenience of rigging installation; 3. By setting the aperture of the limiting block to an outward-expanding trumpet shape, the rigid contact between the cable and the limiting block is reduced, thus avoiding damage to the cable and improving its service life.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, a connection node structure between a steel support and a cable in a cable-stayed curtain wall includes a steel support 1, a cable 2, and a limiting block 3.

[0018] like Figure 1As shown, the steel support 1 includes a fixed pipe 11 and an installation pipe 12. The fixed pipe 11 is horizontally arranged, and the installation pipe 12 passes through the fixed pipe 11 along its diameter. The cable 2 extends from one end of the installation pipe 12 into the installation pipe 12, and a cap 13 is provided at the end of the installation pipe 12 opposite to the end into which the cable 2 enters.

[0019] like Figure 1 As shown, a lock head 21 is provided at the end of the cable 2, and a locking ring 14 is provided inside the mounting tube 12 for the lock head 21 to pass through. A nut 22 for pressing the locking ring 14 is threaded onto the lock head 21.

[0020] like Figure 1 As shown, the limiting block 3 is fitted onto the outer wall of the cable 2 and is located at the opening of the mounting pipe 12, with a gap between the limiting block 3 and the inner wall of the mounting pipe 12.

[0021] Therefore, by setting a limiting block 3 between the steel support 1 and the cable 2, the cable 2 and the reserved hole of the steel support 1 can be isolated. When the cable 2 swings, the cable 2 will not directly contact the steel support 1. Even if there is a collision or friction, it will not affect the cable 2, thus avoiding damage to the cable 2 and improving its service life.

[0022] like Figure 1 , Figure 2 As shown, the limiting block 3 includes a pair of clamping blocks 31, the cross-section of the clamping blocks 31 is semi-circular, a locking gap 32 is provided between the end positions of the pair of clamping blocks 31, and the two ends of the pair of clamping blocks 31 are fixed together by embedded screws 33.

[0023] When the limit block 3 needs to be installed, a pair of clamping blocks 31 are clamped on the outer wall of the cable 2, and then the screw 33 is tightened to fix the pair of clamping blocks 31. At the same time, under the action of the locking gap 32, the pair of clamping blocks 31 will not contact each other when the screw 33 is tightened, thereby achieving stable clamping and fixing of the cable 2.

[0024] like Figure 2 , Figure 3 As shown, the aperture of the limiting block 3 is flared outward from the center to reduce the rigid contact between the cable 2 and the limiting block 3, thereby preventing damage to the cable 2 and improving its service life.

[0025] like Figure 2 , Figure 3 As shown, the two ends of the aperture of the limiting block 3 are provided with inner chamfers 34, which further reduces the rigid contact between the cable 2 and the limiting block 3 when the cable 2 swings, avoids damage to the cable 2, and improves the service life of the cable 2.

[0026] like Figure 2 , Figure 3As shown, the outer wall of the outer end of the limiting block 3 is provided with an outer chamfer 35. On the one hand, this prevents workers from being scratched during installation. On the other hand, it changes the point contact to a surface contact when the limiting block 3 swings and impacts the mounting tube 12, thus avoiding stress concentration and improving the service life of both.

[0027] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
