Description

Technical Field

[0001] This utility model belongs to the field of steel structure building application technology, and specifically relates to a reinforcement connection node for a large-span steel structure arc support. Background Technology

[0002] Steel structure buildings are widely used in large exhibition centers, large factories and other buildings. As a common building form, the connection between its structures and the construction technology are quite mature. Among them, the structural columns and structural beams serve as the supporting skeleton. When the two are connected, a supporting structure is set at the connection point to provide auxiliary support to the beam. The load-bearing pressure on the beam is mostly transmitted by the supporting structure. Therefore, the role of the supporting structure is particularly important.

[0003] The patent CN118601159A, which discloses a curved support node for a large-span steel structure, mentions that commonly used supports, especially pot bearings, are used as supporting structures in large-span steel frame roofs. While these supports have significant advantages, they also have obvious disadvantages, including rubber material aging and maintenance difficulties, which can further affect the stability of the building. Therefore, the patent provides a curved support node that can largely avoid these disadvantages. However, the curved support node also has its own drawbacks that need to be overcome. In the patent, the curved surface support, as a rigid component, is welded to the supporting member. Therefore, when temperature and deflection change, the steel beam and the supporting member will change to varying degrees. This includes slight downward displacement of the steel beam during load-bearing projects, and slight upward displacement of the supporting member and the curved surface support. Such changes can cause the rigid curved surface support to push against the steel beam, and even cause deformation of the supporting part of the steel beam under the support of the curved surface support.

[0004] Therefore, the present invention provides a solution that solves the above problems by using an elastic arc-shaped support plate. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a large-span steel structure arc support reinforcement connection node. By using an elastic arc support plate to support the crossbeam, it can adapt to changes in temperature and deflection that cause changes in the crossbeam and column and provide support.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A large-span steel structure arc-shaped support reinforcement connection node includes a support, a column, and a crossbeam. The crossbeam is fixed to the column by bolts. The support is located below the crossbeam to support it and is also fixed to the column by bolts. The support includes an L-shaped support plate, a first stop block, an arc-shaped support plate, a second stop block, and stiffening plates. The L-shaped support plate is fixed to the column by bolts. A pair of stiffening plates are provided on the side of the L-shaped support plate to improve the support effect. The first stop block is fixed to one end of the upper support plate of the L-shaped support plate, and the second stop block is fixed to the other end of the upper support plate of the L-shaped support plate. The arc-shaped support plate is located on the L-shaped support plate, and its two ends abut against the first stop block and the second stop block. The arc-shaped support plate is made of spring steel plate and has elasticity. The arc-shaped support plate supports the crossbeam to achieve elastic support.

[0008] Furthermore, the L-shaped support plate is provided with a sliding third stop, and the third stop is provided with a rotatably connected screw, which is threadedly connected to the second stop. By rotating the screw, the distance between the third stop and the first stop is controlled and adjusted, thereby pushing the third stop to push one end of the arc-shaped support plate, so that when the arc-shaped support plate experiences elastic fatigue after long-term support, it can push the arc-shaped support plate to maintain its elastic effect again.

[0009] Furthermore, one end of the lead screw is provided with a sliding lever that can be inserted to facilitate the rotation of the lead screw.

[0010] Furthermore, the bottom of the third stop is provided with a guide shaft, one end of which is threaded and connected to the third stop. The guide shaft is inserted into an L-shaped support plate. Correspondingly, the L-shaped support plate is provided with a guide groove, which is used to insert the guide shaft to control the third stop to move linearly.

[0011] Furthermore, mounting blocks are provided on both sides of the arc-shaped support plate, and the mounting blocks are provided with a limiting shaft that can be inserted and slidably. The limiting shaft is close to the end face of the L-shaped support plate to control the arc-shaped support plate and prevent the arc-shaped support plate from sliding left and right and thus slipping off the support of the L-shaped support plate.

[0012] Furthermore, the bottom of the arc-shaped support plate is also provided with an auxiliary support mechanism, including an insert plate, a support plate, a lead screw, and a spring. A pair of insert plates are symmetrically arranged on the inner wall of the arc-shaped support plate. Slots are provided on both sides of the support plate, with a slot depth greater than the length of the insert plate. The insert plate is inserted into the slot. One end of the lead screw is threaded to the support plate. The spring is sleeved on the lead screw. Correspondingly, the L-shaped support plate has a through slot for inserting the lead screw. The spring contacts the L-shaped support plate and the support plate, pushing the support plate and thus the arc-shaped support plate to provide auxiliary thrust. When the crossbeam presses down on the arc-shaped support plate, the arc-shaped support plate will deform due to its elasticity, causing the insert plate to move within the slot, ensuring the auxiliary support effect is achieved.

[0013] Furthermore, the lead screw is provided with a shock-absorbing block that can be inserted and slidably mounted on an L-shaped support plate, and the spring contacts the shock-absorbing block and the support plate.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] In this design, the crossbeam is supported by supports fixed to the columns. Within these supports, an arc-shaped brace directly contacts and supports the crossbeam. Because the arc-shaped brace is made of spring steel, it possesses significant elasticity, enabling flexible support. Furthermore, the arc shape facilitates slight lateral displacement and angular changes in the crossbeam, thus adapting to stress variations in the steel structure caused by temperature changes. This includes slight displacements in the connection between the crossbeam and the column due to temperature and deflection changes, as well as slight vertical displacements in the crossbeam's load-bearing height, avoiding the drawbacks of using rigid arc-shaped supports. Further, to address the elastic fatigue of the arc-shaped brace caused by the downward pressure of the crossbeam, the third stop can be moved or pushed away from the arc-shaped brace by rotating a screw, allowing the apex of the arc-shaped brace to adapt to the support of the crossbeam's bottom surface. Simultaneously, all structural components of the support are disassembled for easy replacement and maintenance.

[0016] Furthermore, limiting shafts are provided on both sides of the arc-shaped support plate. The limiting shafts fit into the side end face of the L-shaped support plate, which can effectively control the arc-shaped support plate and prevent the arc-shaped support plate from sliding left and right and slipping off the support of the L-shaped support plate.

[0028] Based on the above embodiments, one end of the lead screw 17 is provided with a sliding lever 171 that can be inserted into the lead screw 17 to facilitate rotation of the lead screw 17.

[0029] Based on the above implementation, the bottom of the third stop 16 is provided with a guide shaft 161. One end of the guide shaft 161 is threaded and connected to the third stop 16 through the thread. The guide shaft 161 is inserted into the L-shaped support plate 11. Correspondingly, the L-shaped support plate 11 is provided with a guide groove 111. The guide groove 111 is used to insert the guide shaft 161 to control the third stop 16 to move linearly.

[0030] Based on the above embodiments, the arc-shaped support plate 14 is provided with mounting blocks 141 on both sides, and the mounting blocks 141 are provided with limiting shafts 142 that can be inserted and slid.
