Description

Technical Field

[0001] This utility model relates to the technical field of steel structure connectors, and in particular to an adjustable steel structure splicing structure. Background Technology

[0002] The diagonal bracing connector of a steel structure is a key component used to connect the diagonal bracing to the main steel structure and ensure structural stability. It enhances the overall lateral stiffness and stability of the steel structure by reasonably transferring loads, and effectively resists horizontal loads such as wind and earthquakes.

[0003] Currently, traditional node plate connectors are mostly fixed connections. When there are angular or positional deviations in the preset installation positions of steel structural components, it is difficult to make flexible adjustments according to the actual site conditions. This often requires secondary processing or even rework on-site, leading to delays in construction progress. In addition, although the sleeve connectors used can be finely adjusted in length, their ability to lock the support system at multiple angles is insufficient. They cannot effectively deal with the multidimensional deviations that may occur during the installation of steel structures, and they lack effective anti-loosening and limiting structures. During installation, although the length can be finely adjusted through threads, the friction between the threads may not be sufficient to resist lateral forces under dynamic loads or long-term alternating stresses, causing the sleeve to rotate slowly along the axis. Furthermore, the thermal expansion and contraction effect caused by changes in ambient temperature will cause varying degrees of deformation in the materials at the end of the sleeve and the diagonal support, further aggravating the expansion of the thread gap, inducing deflection, and thus easily causing changes in the preset angle of the diagonal support. This will cause the load transfer path to deviate from the design value, resulting in stress concentration in local components and reducing the overall stability of the structure. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable steel structure splicing structure, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable steel structural component splicing structure includes two L-shaped fixing plates. A first L-shaped support beam is fixedly installed on one side of one of the L-shaped fixing plates, and a second L-shaped support beam is fixedly installed on one side of the other L-shaped fixing plate. An L-shaped connecting beam is fixedly installed on the side of the second L-shaped support beam opposite to the first L-shaped support beam. Friction rings are also movably installed between the two L-shaped fixing plates and the first L-shaped support beam and the second L-shaped support beam, respectively.

[0007] As a further preferred embodiment of this utility model, two L-shaped fixing seats are fixedly installed on one side of the L-shaped fixing plate. By setting two L-shaped fixing seats on one side of the L-shaped fixing plate, the L-shaped fixing plate can be pre-inserted into one side of the I-beam through the two L-shaped fixing seats, thereby providing additional support force for the L-shaped fixing plate, the first L-shaped support beam, and the second L-shaped support beam after the structure is fixed.

[0008] As a further preferred embodiment of this utility model, a first connecting hole is provided on one side of the L-shaped fixing plate. The first connecting hole allows the first L-shaped support beam and the second L-shaped support beam to be adjusted by rotating around the axis in sequence with bolts. A plurality of connecting slots are also provided on one side of the L-shaped fixing plate, and the plurality of connecting slots are coaxial with the first connecting hole. The axis points of the connecting slots and the first connecting hole are at the same position, thereby ensuring that the multiple bolts at one end of the first L-shaped support beam or the second L-shaped support beam can move smoothly in the corresponding connecting slots, thereby facilitating the installation angle of the first L-shaped support beam and the second L-shaped support beam.

[0009] As a further preferred embodiment of this utility model, the first L-shaped support beam has a second connecting hole, and the first L-shaped support beam located on both sides of the second connecting hole also has a plurality of third connecting holes. The second L-shaped support beam also has a second connecting hole, and the second L-shaped support beam located on both sides of the second connecting hole also has a plurality of third connecting holes. Bolts are inserted between the second connecting hole and the corresponding first connecting hole, and bolts are also inserted between the plurality of third connecting holes and the corresponding connecting slots. The first L-shaped support beam and the second L-shaped support beam are respectively installed on one side of the corresponding L-shaped fixing plate by bolts, and the first L-shaped support beam and the second L-shaped support beam can rotate about the bolt between the second connecting hole and the first connecting hole as the axis, thereby synchronously driving the bolts between the plurality of third connecting holes and the connecting slots to move synchronously, providing a stable foundation for the subsequent fastening connection between the L-shaped fixing plate and the first L-shaped support beam or the L-shaped fixing plate and the second L-shaped support beam.

[0010] As a further preferred embodiment of this utility model, a slot is provided in the L-shaped connecting beam, and multiple fourth connecting holes are provided on both sides of the slot. The slot is inserted and installed on one side of the first L-shaped support beam, and bolts are inserted and connected between the fourth connecting holes and multiple third connecting holes in the first L-shaped support beam. The first L-shaped support beam and the second L-shaped support beam are inserted and connected through the L-shaped connecting beam, which facilitates the adaptive adjustment of the overall structural length of the first L-shaped support beam and the second L-shaped support beam when the angle of the structure of the first L-shaped support beam and the second L-shaped support beam is adjusted.

[0011] As a further preferred embodiment of this utility model, the friction ring includes a metal ring, with mounting grooves on both sides of the metal ring. A rubber ring is inserted and installed in the mounting groove, and the metal ring is inserted and installed on the bolt between the L-shaped fixing plate and the first L-shaped support beam or the L-shaped fixing plate and the second L-shaped support beam. By setting the metal ring and the rubber ring, the frictional resistance between the L-shaped fixing plate and the first L-shaped support beam or the L-shaped fixing plate and the second L-shaped support beam can be increased, thereby improving the connection strength between the L-shaped fixing plate and the first L-shaped support beam or the L-shaped fixing plate and the second L-shaped support beam, and ensuring the stability of its overall structure.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this utility model, the support structure composed of two L-shaped fixing plates, a first L-shaped support beam, a second L-shaped support beam, and an L-shaped connecting beam can easily achieve multi-angle locking of the support system within a certain range according to the actual installation situation on site. This allows for the correction of deviations in the preset installation positions of some steel structural components, ensuring the normal progress of the overall construction.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-4As shown, the present invention provides an adjustable steel structure splicing structure, including two L-shaped fixing plates 1. A first L-shaped support beam 2 is fixedly installed on one side of one L-shaped fixing plate 1, and a second L-shaped support beam 3 is fixedly installed on one side of the other L-shaped fixing plate 1. An L-shaped connecting beam 4 is fixedly installed on the side of the second L-shaped support beam 3 relative to the first L-shaped support beam 2. Friction rings 5 ​​are also movably installed between the two L-shaped fixing plates 1 and the first L-shaped support beam 2 and the second L-shaped support beam 3, respectively.

[0021] like Figures 1-2 As shown, two L-shaped fixing seats 7 are fixedly installed on one side of the L-shaped fixing plate 1. The two L-shaped fixing seats 7 on one side of the L-shaped fixing plate 1 allow the L-shaped fixing plate 1 to be pre-inserted into one side of the I-beam 6 through the two L-shaped fixing seats 7, thereby providing additional support force for the L-shaped fixing plate 1, the first L-shaped support beam 2, and the second L-shaped support beam 3 after the structure is fixed.

[0022] like Figures 1-4As shown, a first connecting hole 8 is provided on one side of the L-shaped fixing plate 1. The first connecting hole 8 allows the first L-shaped support beam 2 and the second L-shaped support beam 3 to be adjusted by rotating around the axis sequentially using bolts. Multiple connecting slots 9 are also provided on one side of the L-shaped fixing plate 1, and these slots are coaxial with the first connecting hole 8. The axis points of the connecting slots 9 and the first connecting hole 8 are at the same position, thus ensuring that multiple bolts at one end of the first L-shaped support beam 2 or the second L-shaped support beam 3 can move smoothly within the corresponding connecting slots 9, facilitating the installation angle of the first L-shaped support beam 2 and the second L-shaped support beam 3. A second connecting hole 10 is provided inside the first L-shaped support beam 2. The first L-shaped support beam 2 is located on both sides of the second connecting hole 10. The support beam 2 is also provided with multiple third connecting holes 11. The second L-shaped support beam 3 is also provided with a second connecting hole 10. The second L-shaped support beam 3 located on both sides of the second connecting hole 10 is also provided with multiple third connecting holes 11. Bolts are inserted between the second connecting hole 10 and the corresponding first connecting hole 8. Bolts are also inserted between the multiple third connecting holes 11 and the corresponding connecting slots 9. The first L-shaped support beam 2 and the second L-shaped support beam 3 are respectively installed on one side of the corresponding L-shaped fixing plate 1 by bolts, so that the first L-shaped support beam 2 and the second L-shaped support beam 3 can rotate about the bolt between the second connecting hole 10 and the first connecting hole 8 as the axis, thereby synchronously driving the multiple third connecting holes 11. The bolts between hole 11 and connecting slot 9 move synchronously, providing a stable foundation for the subsequent fastening connection between L-shaped fixing plate 1 and first L-shaped support beam 2 or L-shaped fixing plate 1 and second L-shaped support beam 3. A slot 12 is provided inside the L-shaped connecting beam 4, and multiple fourth connecting holes 13 are provided on both sides of the slot 12. The slot 12 is inserted and installed on one side of the first L-shaped support beam 2, and bolts are inserted and connected between the fourth connecting holes 13 and multiple third connecting holes 11 inside the first L-shaped support beam 2. The first L-shaped support beam 2 and the second L-shaped support beam 3 are connected by the L-shaped connecting beam 4, which facilitates the adjustment of the angle of the first L-shaped support beam 2 and the second L-shaped support beam 3 structure. To adapt to the overall structural length adjustment of the second L-shaped support beam 3, the friction ring 5 includes a metal ring 14. Both sides of the metal ring 14 have mounting grooves 15, and rubber rings 16 are inserted into the mounting grooves 15. The metal ring 14 is inserted into the bolts between the L-shaped fixing plate 1 and the first L-shaped support beam 2, or between the L-shaped fixing plate 1 and the second L-shaped support beam 3. The metal ring 14 and rubber rings 16 increase the frictional resistance between the L-shaped fixing plate 1 and the first L-shaped support beam 2, or between the L-shaped fixing plate 1 and the second L-shaped support beam 3, thereby increasing the connection strength between the L-shaped fixing plate 1 and the first L-shaped support beam 2, or between the L-shaped fixing plate 1 and the second L-shaped support beam 3, ensuring the overall structural stability.

[0023] It should be noted that this utility model is an adjustable steel structure splicing structure. In use, two L-shaped fixing plates 1 are pre-inserted into the main steel structure such as the I-beam 6 through the L-shaped fixing seat 7 on one side. Then, when the two L-shaped fixing plates 1 are connected by the first L-shaped support beam 2, the second L-shaped support beam 3, and the L-shaped connecting beam 4, the first connecting hole 8 of the L-shaped fixing plate 1 is hinged to the second connecting hole 10 of the first L-shaped support beam 2 or the second L-shaped support beam 3 by bolts to form a rotation axis. Connecting bolts are inserted between the multiple third connecting holes 11 in the first L-shaped support beam 2 and the second L-shaped support beam 3 and the multiple connecting slots 9 in the corresponding L-shaped fixing plate 1, so that the first L-shaped support... One end of the support beam 2 is inserted into the slot 12. The installation positions of the two L-shaped fixing plates 1 on the corresponding I-beams 6 allow the first L-shaped support beam 2 and the second L-shaped support beam 3 to rotate and adjust their angles on the corresponding side of the L-shaped fixing plate 1. One end of the first L-shaped support beam 2 moves and inserts within the slot 12 as the angles of the first L-shaped support beam 2 and the second L-shaped support beam 3 are adjusted. After the angle and length are adjusted, the bolts are tightened to achieve multi-angle locking. The rubber rings 16 on both sides of the metal ring 14 abut against one side of the L-shaped fixing plate 1 or one side of the first L-shaped support beam 2 or the second L-shaped support beam 3, thereby using the elastic friction generated by the rubber rings 16 to improve the anti-slip ability and suppress the rotation tendency of the support beam.
