Description

Technical Field

[0001] This utility model relates to the field of building structure engineering technology, specifically to a building support column with shock absorption function. Background Technology

[0002] In the field of building structures, support columns are key components for bearing and transmitting loads. Traditional building support columns are mostly rigid columns, which, while providing stable support, pose significant safety hazards when facing dynamic loads such as earthquakes and strong winds. For example, seismic energy can be directly transmitted to the building structure through rigid columns, easily leading to brittle failure of structural components (such as beams and columns) or connection nodes, posing a serious threat to building safety.

[0003] To improve the seismic performance of buildings, existing technologies often involve installing dampers separately in the building structure or using special flexible supports. However, these solutions typically suffer from problems such as structural complexity, large space occupation, high requirements for connection nodes with the main structure, and high manufacturing costs. For example, separately installed dampers require precise design and complex connection structures, increasing construction difficulty and cost. At the same time, the top node construction of existing support columns also has unreasonable aspects, making it difficult to evenly distribute the upper load, affecting the overall stability and safety. Utility Model Content

[0004] (I) Technical Issues

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a building support column with shock absorption function. This column can simultaneously have stability and excellent shock absorption function. It has a compact structure, does not require additional building space to install independent dampers, and can evenly distribute the load to avoid stress concentration.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0008] A building support column with shock absorption function includes an upper support base, a lower support plate, and a herringbone support structure connecting the two. The herringbone support structure is formed by two symmetrically arranged diagonal columns converging at the top. Vertically arranged shock absorption components are provided inside the diagonal columns.

[0009] The upper support is fixed at the intersection of the two inclined columns, and the lower support plate is fixed to the bottom of the two inclined columns respectively.

[0010] As an improvement, the shock absorption assembly includes an upper connecting plate, a lower connecting plate, and an intermediate layer disposed between the two; the inclined column has a cavity in the middle, and the upper connecting plate and the lower connecting plate are respectively connected to the upper and lower parts of the cavity by bolts.

[0011] As an improvement, the intermediate layer has a cylindrical structure and is made of alternating layers of sandwich steel plates and thin rubber layers bonded together. A lead core is inserted through the axis of the intermediate layer, and the two ends of the lead core are rigidly connected to the upper connecting plate and the lower connecting plate, respectively.

[0012] As an improvement, the upper support includes an inclined plate integrally formed on the top of two inclined columns. A triangular plate is vertically fixed to the longitudinal direction of the inclined plate. The triangular plate is an isosceles triangle structure and is inverted with its longest side facing upwards.

[0013] As an improvement, all three corners of the triangular plate are beveled to avoid stress concentration.

[0014] As an improvement, the longest side of the triangular plate is fixedly connected to a U-shaped groove for positioning and installing the crossbeam. The opening of the U-shaped groove faces upward, and its bottom plate is fixed to the top edge of the triangular plate by welding.

[0017] 1. This utility model integrates the shock absorption component into the herringbone-shaped inclined column, enabling the support column to simultaneously possess stability and excellent shock absorption function. The structure is compact and does not require additional building space to install an independent damper.

[0018] 2. The inclined columns with a herringbone structure of this utility model have good stability.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] A type of building support column with shock absorption function, such as Figure 1 , 4 As shown, it includes:

[0027] The system comprises an upper support base 1, a lower support plate 2, and a herringbone support structure connecting the two. The herringbone support structure consists of two symmetrically arranged diagonal columns 3 converging at the top to form a stable triangular support frame. Each diagonal column 3 has a vertically arranged shock-absorbing component 4 inside. The shock-absorbing component 4 includes an upper connecting plate 5, a lower connecting plate 7, and an intermediate layer 6 disposed between the two. Each diagonal column 3 has a cavity in its middle. The upper connecting plate 5 and the lower connecting plate 7 are bolted to the upper and lower sections of the cavity, respectively. The intermediate layer 6 is a cylindrical structure made of alternating layers of sandwich steel plates and thin rubber layers. This sandwich structure has high vertical stiffness under pressure, ensuring load-bearing capacity. Under horizontal shear deformation, the rubber layer can undergo large deformation to dissipate energy. A lead core 8 is inserted through the axis of the intermediate layer 6. The two ends of the lead core 8 are rigidly connected to the upper connecting plate 5 and the lower connecting plate 7, respectively. Under seismic action, the lead core 8 will enter a plastic state due to shear action and absorb a large amount of seismic energy through plastic deformation.

[0028] like Figure 2 , 3 As shown, the upper support base 1 is fixed at the intersection of two inclined columns 3, and the lower support plate 2 is fixed to the bottom ends of the two inclined columns 3 respectively, and fixed to the building foundation or lower structure; the upper support base 1 includes an inclined plate 9 integrally formed on the top of the two inclined columns 3, and a triangular plate 10 is vertically fixed to the longitudinal direction of the inclined plate 9. The triangular plate 10 is an isosceles triangle structure, and it is inverted with the longest side facing upward. This mechanism can effectively decompose the concentrated load from above into two inclined components and transmit them to the two inclined columns. To the column 3, the stress path is optimized. The three corners of the triangular plate 10 are beveled to avoid stress concentration. The longest side of the triangular plate 10 is fixedly connected to a U-shaped groove 11 for positioning and installing the crossbeam. The lower end of the triangular plate 10 extends into the interior of the inclined columns 3 on both sides. The opening of the U-shaped groove 11 faces upward. Its bottom plate is fixed to the top edge of the triangular plate 10 by welding. Several evenly distributed reinforcing ribs 12 are provided at the connection between the bottom plate of the U-shaped groove 11 and the triangular plate 10 to enhance the strength of the connection.

[0029] In the specific implementation of this embodiment:

[0030] First, the lower support plate 2 is firmly fixed to the building foundation or lower structure using anchor bolts and other components. Then, the bottom ends of the two inclined columns 3 with built-in shock absorbers 4 are fixed to the lower support plate 2, and their tops are connected by the upper support seat 1 to form a herringbone structure. During installation, the U-shaped groove 11 precisely engages and fixes the crossbeam. The inverted triangular plate 10, together with the two inclined plates 9, can evenly distribute the concentrated load from the upper crossbeam to the two inclined columns 3. At the same time, several evenly distributed reinforcing ribs 12 below the U-shaped groove 11 enhance the stability of the connection with the crossbeam and the local load-bearing capacity.

[0031] When an earthquake triggers horizontal vibrations in the structure, the force causes shear deformation in the damping component 4 in the middle of the inclined column 3. At this time, the thin rubber layer of the intermediate layer 6 undergoes large deformation, and the lead core 8 quickly enters a plastic state. The two work together to efficiently dissipate a large amount of seismic energy through hysteretic deformation. Meanwhile, the vertical load-bearing capacity of the structure is guaranteed by the sandwich steel plate in the intermediate layer 6, thus achieving an organic combination of load-bearing and damping functions.

[0032] Unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
