Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable-stayed support node technology, and specifically to a novel cable-stayed support node structure. Background Technology
[0002] A cable-stayed brace joint is a critical component in a building structure used to connect cable-stayed braces to other structural members (such as beams, columns, and frames). It is commonly used in high-rise buildings, long-span structures, and bridges. Its main function is to transfer the force of the cable-stayed brace to other structural parts, while ensuring the stability and safety of the structure.
[0003] Currently, the commonly used connection methods between round steel supports, thin-walled purlins, and rectangular tubes or other steel sections in cable-stayed joints have the following technical drawbacks:
[0004] 1. Welded connection: The round steel support and purlins are directly welded to the surface of the rectangular tube, or stiffening plates (steel plates or angle steel) are first welded onto the rectangular tube and then the remaining components are welded onto the stiffening plates. Although this joint treatment method saves material costs and reduces the number of components, it is difficult to construct, requires precise positioning, and the heat-affected zone of welding may reduce the material properties. Moreover, later maintenance or adjustment is also particularly difficult.
[0005] 2. Sleeve connection: A sleeve is welded onto the rectangular tube, and the round steel is inserted into the sleeve and fixed with bolts or pins. The purlin and the rectangular tube are connected with common bolts. This node treatment method uses prefabricated connectors in the factory, which makes the quality relatively controllable. The angle or position can be adjusted, which is suitable for complex nodes. However, it requires customized connectors, which is more expensive. If the connector is damaged, replacing it with a matching model connector is too dependent on the parts supplier.
[0006] 3. Bolted connection: Two clamps are used to hold the round steel and rectangular tube together and then fixed with bolts; or a flange is welded to the end of the round steel and bolted to the flange on the rectangular tube (the purlin and rectangular tube are also bolted together): This joint treatment method is convenient to construct and can be disassembled, which is convenient for later maintenance or structural adjustment. However, its joint rigidity is low, it relies on bolt preload, and has high precision requirements. The holes need to be precisely aligned, and the additional clamps or flanges increase material costs. Utility Model Content
[0007] (a) Technical problems to be solved
[0008] The technical problem to be solved by this utility model is to provide a new type of cable-stayed support node structure with high assembly efficiency and good installation quality, in light of the current state of the technology.
[0009] (II) Technical Solution
[0010] This utility model is achieved through the following technical solution: This utility model proposes a novel inclined support node structure, including a rectangular tube, on which a prefabricated angle steel connector is installed. A connector welding plate is installed on one side wall of the angle steel connector. A purlin one is installed on one side of the angle steel connector, and a purlin two is installed on the other side of the angle steel connector. A connecting bolt one is installed at the connection between the angle steel connector and the purlin one, and a connecting bolt two is installed at the connection between the angle steel connector and the purlin two. A round steel inclined support is installed on the connector welding plate through a connecting bolt three. Adjustment holes are reserved on the angle steel connector at the locations of the connecting bolt one, the connecting bolt two, and the connecting bolt three. The end of the round steel inclined support is flattened and pre-drilled.
[0011] Furthermore, the connecting plate is welded to the angle steel connecting piece, and the connecting plate has an inclined structure.
[0012] Furthermore, the connecting bolt passes through the angle steel connector and is threadedly connected to the purlin.
[0013] Furthermore, the second connecting bolt passes through the angle steel connector and is threadedly connected to the second purlin.
[0014] Furthermore, the rectangular tube passes through the angle steel connector, and the angle steel connector is welded to the rectangular tube.
[0015] Furthermore, the connecting bolt three penetrates the round steel diagonal support and the connecting plate, and the free end of the connecting bolt three is locked and limited by a nut.
[0016] Furthermore, the connecting bolt one, the connecting bolt two, and the connecting bolt three have the same structural dimensions, and the gap between the adjusting hole and the connecting bolt one is 4mm.
[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model has the following advantages:
[0019] This invention utilizes prefabricated angle steel connectors installed between rectangular tubes and purlins one and two. Adjustment holes are pre-drilled at the connection points between the angle steel connectors and purlins one and two, and at the connection points between the welded plate of the connector and the round steel diagonal support. This design effectively reduces cutting and welding processes during installation, significantly improving assembly efficiency. Furthermore, the positions of the rectangular tube, purlins one and two, and the round steel diagonal support can be adjusted on-site by ±2mm using the adjustment holes to accommodate installation errors. The flattened end design of the round steel diagonal support increases the contact area, reducing reliance on hole precision and improving installation quality. Additionally, the bolted connections are detachable, facilitating partial replacement or structural modifications. On-site welding is reduced, saving welding and labor costs. Damaged components can be replaced, preventing overall structural scrapping and resulting in high material reuse rates. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0025] like Figures 1-2As shown, a novel inclined support node structure in this embodiment includes a rectangular tube 2, on which a prefabricated angle steel connector 4 is installed. A connector welding plate 5 is installed on one side wall of the angle steel connector 4. A purlin 3 is installed on one side of the angle steel connector 4, and a purlin 6 is installed on the other side. A connecting bolt 7 is installed at the connection between the angle steel connector 4 and the purlin 3, and a connecting bolt 8 is installed at the connection between the angle steel connector 4 and the purlin 6. A round steel inclined support 1 is installed on the connector welding plate 5 via a connecting bolt 9. Adjustment holes 10 are reserved at connecting bolts 1-7, 2-8, and 3-9. The end of the round steel diagonal support 1 is flattened and pre-drilled. The treatment of angle steel connector 4, connector welding plate 5, and round steel diagonal support 1 is completed in advance, reducing on-site cutting and welding procedures. Only tying is required on-site, which improves the construction speed. The positions of rectangular tube 2, purlin 1-3, purlin 2-6, and round steel diagonal support 1 can be adjusted on-site by ±2mm to accommodate installation errors. The flattened end design of round steel diagonal support 1 increases the contact area and reduces the dependence on hole position accuracy.
[0026] like Figures 1-2 As shown, in this embodiment, the connecting plate 5 is welded to the angle steel connecting piece 4. The connecting plate 5 has an inclined structure. The welding connection method can ensure the reliable fixation of the connecting plate 5 on the angle steel connecting piece 4. The connecting bolt 1 7 passes through the angle steel connecting piece 4 and is threaded to the purlin 1 3. The connecting bolt 1 7 is mainly used to connect the purlin 1 3 to the angle steel connecting piece 4. The connecting bolt 2 8 passes through the angle steel connecting piece 4 and is threaded to the purlin 2 6. The connecting bolt 2 8 is mainly used to connect the purlin 2 6 to the angle steel connecting piece 4.
[0027] like Figures 1-2 As shown, in this embodiment, the rectangular tube 2 passes through the angle steel connector 4, and the angle steel connector 4 is welded to the rectangular tube 2. The rectangular tube 2 is mainly used to provide an installation foundation for the angle steel connector 4, and it also plays a supporting and reinforcing role. The connecting bolt 3 9 passes through the round steel diagonal support 1 and the connector welding plate 5, and the free end of the connecting bolt 3 9 is locked and limited by a nut. The connecting bolt 3 9 is mainly used to connect the round steel diagonal support 1 and the connector welding plate 5. The connecting bolt 1 7, connecting bolt 2 8 and connecting bolt 3 9 have the same structural dimensions, and the gap between the adjusting hole 10 and the connecting bolt 1 7 is 4mm. The reserved gap of 4mm can ensure that the purlin 1 3, purlin 2 6 and round steel diagonal support 1 have sufficient adjustment space during installation to meet the rapid assembly requirements of the diagonal support node.
[0028] The specific implementation process of this embodiment is as follows: First, purlin 3 is connected to angle steel connector 4 using connecting bolt 7, and purlin 6 is connected to angle steel connector 4 using connecting bolt 8. Then, the round steel diagonal support 1 is connected to the connector welding plate 5 using connecting bolt 9, thus enabling the diagonal bracing node to be put into use. During use, under the action of angle steel connector 4 and adjusting hole 10, the diagonal bracing node can effectively reduce cutting and welding processes during actual installation, thereby improving the assembly efficiency of the diagonal bracing node. The installation quality is significantly improved, and the positions of the rectangular tube 2, purlin 1 3, purlin 2 6, and round steel diagonal support 1 can be adjusted on-site by ±2mm under the action of the adjustment hole 10, which can accommodate installation errors. At the same time, the flattened end design of the round steel diagonal support 1 increases the contact area and reduces the dependence on the accuracy of the hole position, resulting in better installation quality of the diagonal support node. In addition, the bolt connection is detachable, which facilitates partial replacement or structural modification; the amount of on-site welding work is reduced, saving welding costs and labor costs; each component can be replaced after damage, avoiding the scrapping of the entire structure, and the material reuse rate is high.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
