Description

Technical Field

[0001] The present invention relates to the technical field of earthquake-resistant supports, and more particularly to a position-limiting tension-compression spring support. Background Art

[0002] With the acceleration of urbanization in China, the height and complexity of buildings are constantly increasing, and the seismic performance and stability of structures are becoming increasingly important. Currently, vibration isolation bearings have a huge scope of use and are widely used in various fields. However, traditional building materials and bearing designs are difficult to meet the high standards of safety and durability in modern engineering and have certain limitations. Common ordinary bearings may fatigue under high-frequency vibrations, forcing them to reduce their service life; or they may be unable to effectively cope with structural displacement, which can easily lead to local stress concentration and ultimately cause structural damage. Therefore, the emergence of new bearing technologies is needed in related fields to better adapt to these extreme conditions.

[0003] Therefore, how to effectively resist lateral impact or maintain stability under extreme conditions and provide a support structure with good seismic resistance and simple construction and installation is an urgent problem that needs to be solved by technical personnel in this field.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1:

[0035] See attached Figure 1 , Attachment Figure 2 , Attachment Figure 5 and attached Figure 6 The embodiment of the present invention discloses a non-shear-resistant limited tension and compression spring support, comprising an upper column 1 and a lower base 6; a coil spring support is connected between the upper column 1 and the lower base 6; the coil spring support comprises:

[0036] Upper steel plate 2, upper steel plate 2 is fixed to the bottom surface of upper column 1;

[0037] The lower steel plate 5 is fixed to the top surface of the lower foundation 6. A supporting steel pipe 10 is fixed to the top surface of the lower steel plate 5. The top edge of the supporting steel pipe 10 has an upper flange platform protruding radially outward. A compression gap is formed between the upper flange platform and the upper steel plate 2.

[0038] The coil spring 9 is fixedly connected between the upper steel plate 2 and the lower steel plate 5 and is located inside the supporting steel tube 10 .

[0039] In this embodiment, the upper steel plate 2 serves as the top structure of the coil spring support and is connected to the column foot portion of the upper column 1 above the upper steel plate 2 , and the connection method can be welding or bolt fastening.

[0040] Furthermore, the coil spring 9 is connected to the upper steel plate 2 and the lower steel plate 5 by welding or bolts, and the gap is compressed to allow the spring to be fully compressed.

[0041] In order to further optimize the above technical solution, a rubber pad 3 is fixed to the top surface of the upper flange platform.

[0042] To further optimize the above technical solution, an anchor rod 8 embedded in the lower foundation 6 is fixed to the bottom surface of the lower steel plate 5. The connection between the lower steel plate 5 and the anchor rod 8 can be welding or bolting; the anchor rod 8 is embedded in the lower foundation 6, thereby fixing the entire support.

[0043] In order to further optimize the above technical solution, a support structure 4 is fixed between the upper flange platform and the outer wall of the supporting steel pipe 10 .

[0044] In this embodiment, one end of the support structure 4 is fixed to the edge of the upper flange platform of the support steel pipe 10 , and the other end is fixed to the pipe wall of the support steel pipe 10 .

[0045] In order to further optimize the above technical solution, the bottom edge of the supporting steel pipe 10 has a lower flange platform protruding radially outward, and the lower flange platform is connected to the lower steel plate 5 through a fixing nut and bolts 7.

[0046] In order to further optimize the above technical solution, the diameter of the lower flange platform is smaller than the diameter of the upper flange platform.

[0047] In order to further optimize the above technical solution, the inner wall diameter of the supporting steel pipe 10 is larger than the outer diameter of the coil spring 9 .

[0048] In order to further optimize the above technical solution, the upper steel plate 2, fixing nuts and bolts 7, supporting steel pipe 10, coil spring 9, supporting structure 4 and lower steel plate 5 can be made of ordinary Q235 steel, low yield point steel or SMA, that is, shape memory alloy superelastic rod, etc.

[0049] In order to further optimize the above technical solution, the rubber pad 3 can be made of natural rubber, lead rubber or high damping rubber.

[0050] Specifically, in this embodiment, both the upper steel plate 2 and the lower steel plate 5 have openings serving as connection ports for fixing nuts and bolts 7 , and the upper steel plate 2 and the lower steel plate 5 are arranged in parallel.

[0051] The lower flange platforms supporting the steel pipes 10 are all punched with holes, and the punching positions correspond to the opening positions of the lower steel plate 5. The above components are fixed by a number of fixing nuts and bolts.

[0052] When this embodiment is in use, if the coil spring 9 is insufficient to provide the bearing force, the rubber pad 3 , the supporting steel pipe 10 and the supporting structure 4 will provide the bearing force.

[0053] This embodiment overcomes the shortcomings of traditional supports in terms of load-bearing capacity and seismic resistance, enhancing the stability and safety of the structure under extreme working conditions. The design of this support effectively improves the overall vertical load-bearing capacity when subjected to vertical loads, limiting the deformation limit of the spring. It also simplifies construction and assembly, reducing engineering costs.

[0054] Example 2:

[0055] See attached Figure 3 To the attached Figure 6The embodiment of the present invention discloses a shear-resistant limiting tension and compression spring support. This embodiment is further improved on the basis of Example 1: it also includes a limiting steel pipe 11, the top edge of the limiting steel pipe 11 is fixed to the bottom surface of the upper steel plate 2, and the limiting steel pipe 11 is located on the outside of the coil spring 9. The limiting steel pipe 11 is coaxially arranged with the supporting steel pipe 10, and the lower part of the limiting steel pipe 11 extends to the inside of the supporting steel pipe 10.

[0056] In order to further optimize the above technical solution, a gap is left between the outer wall of the limiting steel pipe 11 and the inner wall of the supporting steel pipe 10 for the two to perform vertical relative movements.

[0057] In this embodiment, there is a small gap between the lower end of the limiting steel pipe 8 extending into the tube body of the supporting steel pipe 10 and the inner wall of the supporting steel pipe 10; that is, there can only be relative displacement in the vertical direction between the limiting steel pipe 8 and the supporting steel pipe 10, and no relative displacement in the horizontal direction occurs.

[0058] In order to further optimize the above technical solution, the top edge of the limiting steel pipe 11 has a connecting flange protruding radially outward, and the connecting flange is connected to the upper steel plate 2 through a fixing nut and a bolt 7.

[0059] In this embodiment, the connecting flange of the limiting steel pipe 8 and the lower flange platform of the supporting steel pipe 10 are both punched, and the punching positions correspond to the opening positions of the upper steel plate 2 and the lower steel plate 5 respectively. The above components are fixed by a number of fixing nuts and bolts.

[0060] When this embodiment is in use, if the bearing force is unevenly distributed on the upper steel plate 2, causing the coil spring 9 to shake left and right, the limiting steel pipe 8 will provide anti-shear bearing force to limit the shaking of the coil spring 9.

[0061] If the coil spring 9 is insufficient to provide the bearing force, the rubber pad 3 , the supporting steel pipe 10 and the supporting structure 4 will provide the bearing force.

[0062] The other structures of this embodiment are the same as those of embodiment 1 and will not be described again here.

[0063] This embodiment overcomes the shortcomings of traditional bearings in terms of bearing capacity and seismic resistance, enhancing the stability and safety of the structure under extreme working conditions. The bearing design effectively reduces lateral displacement when subjected to longitudinal and transverse loads, improving overall vertical bearing capacity and shear resistance. Construction and assembly are also relatively simple, reducing project costs.
