Description

A self-resetting assembled column support

Technical Field

The present invention relates to the technical field of building structure engineering, in particular to an assembled steel structure column support, and specifically to a self-resetting assembled column support.

Background technique

In the field of construction, prefabricated steel structures are widely used in large factories, stadiums, and residential areas due to their good earthquake resistance, economic and environmental advantages. The purpose of the steel structure column support is to ensure the overall stability of the steel structure factory, improve the lateral stiffness, and transmit the longitudinal horizontal force.

Heavy industrial plants generally use double-piece column supports, and the two support rods are connected by tie rods. However, the existing connection method between tie rods and supports is mainly welding, which greatly increases the installation time of column supports, prolongs the construction progress, and reduces construction efficiency.

In addition, when facing extreme conditions such as earthquakes, the column supports are prone to irreversible deformation under vibration, resulting in a decline in structural performance and posing safety hazards.

Existing technologies mostly focus on improving the rigidity or shock absorption capacity of the structure. Although these methods can improve the seismic performance of the structure, they often cannot solve the problem of recovering structural deformation after an earthquake.

Based on the above problems, it is necessary to propose a self-resetting assembled column support that can improve construction efficiency and restore the deformed parts to their original shape after an earthquake.

Summary of the invention

In view of the deficiencies in the prior art, the main purpose of the present invention is to provide a self-resetting assembled column support to solve one or more problems in the prior art.

The technical solution of the present invention is as follows:

The present invention provides a self-resetting assembled column support, comprising:

The inter-column support body comprises two support rods arranged in parallel and obliquely on one side and two support rods arranged in parallel and obliquely on the other side, wherein the two support rods on one side cross the two support rods on the other side to form an X shape;

Tie rod connection components, provided with a plurality of groups, are arranged along two sides between two support rods arranged in an inclined and parallel manner on each side, and connect the two support rods on the same side;

The end connecting components are arranged at both ends of the supporting rod and are connected and fixed to the other end of the end self-resetting component or the supporting rod.

In some embodiments, the two support rods on one side of the X-shaped inter-column support body are disconnected along the middle intersection position, and are fixed to the two support rods on the other side at the disconnected position through a middle connecting plate and bolts.

In some embodiments, the tie rod connection assembly is transversely arranged between the two support rods, and includes a main connection plate and two end connection plates. The length of the main connection plate is greater than that of the end connection plate. The two end connection plates are respectively connected and fixed to the two support rods by a group of bolts, and the two ends of a main connection plate are respectively connected and fixed to the two end connection plates by another group of bolts.

In some embodiments, the energy-absorbing connection assembly includes two outer steel plates and two embedded solid viscoelastic material layers. The two outer steel plates are overlapped and arranged, and the two embedded solid viscoelastic material layers are embedded between the two outer steel plates. The two embedded solid viscoelastic material layers are separated by a gap, and the gap is used to insert the end self-resetting member.

In some embodiments, the length of the two embedded solid viscoelastic material layers is less than the length of the outer steel plate, and the two embedded solid viscoelastic material layers are respectively connected and fixed to the corresponding outer steel plates.

In some embodiments, the energy-absorbing connection component also includes two embedded steel pads, which are stacked together. Two corresponding embedded solid viscoelastic material layers along one end of the energy-absorbing connection component are embedded between the two outer steel plates, and a gap equal to the two embedded solid viscoelastic material layers is reserved in the middle, and the gap is used to insert the support rod.

In some embodiments, the support rod is a channel steel; the two outer steel plates and the embedded steel pad are both channel steels, and the two embedded solid viscoelastic material layers are corresponding groove shapes.

In some embodiments, the thickness of the embedded steel backing plate is the same as the thickness of the embedded solid viscoelastic material layer.

In some embodiments, the end self-resetting member is a support member made of shape memory alloy.

In some embodiments, the end connection member comprises an end connection plate, and a surface of the end connection plate is coated with a layer of carbon fiber.

The beneficial effects of the present invention over the prior art are as follows: the self-resetting assembled column support proposed by the present invention is suitable for heavy industrial plants, and is arranged as a supporting member between two adjacent columns of heavy industrial plants. The self-resetting assembled column support can restore the deformation of the structure after the earthquake, and at the same time improve the construction efficiency. Specifically, it has at least the following practical effects: the present invention connects the support rods on each side of the X-shaped column support body with bolts through a tie rod connection assembly. This assembled construction greatly reduces the installation time of the column support, shortens the construction progress, and improves the construction efficiency.

Although the initial investment of such a design may be relatively high, in the long run, it has a high cost-effectiveness overall due to its low maintenance cost and long service life. It should be understood that the realization of any embodiment of the present invention does not mean that multiple or all of the above-mentioned beneficial effects must be possessed or achieved at the same time.

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

The implementation of the present invention is described in detail below in conjunction with preferred embodiments.

As shown in Figures 1 to 11, the present invention proposes a self-resetting assembled column support, which is particularly suitable for heavy industrial plants and is arranged between two adjacent columns of heavy industrial plants as a supporting member of heavy industrial plants. The assembled design of the self-resetting assembled column support can improve the construction efficiency of the overall structure and can also restore the deformation of the structure caused by an earthquake.

Specifically, the self-resetting assembled inter-column support includes an inter-column support body 100 , a tie rod connection assembly 2 , an energy-dissipating connection assembly 4 , an end self-resetting member 5 and an end connection member 6 .

In order to ensure the overall stability of the steel structure workshop, improve the lateral rigidity and transmit the longitudinal horizontal force, heavy industrial workshops need to use double-sheet column support. Double-sheet column support means that both sides are used as fulcrums to bear the weight of the structure. Relatively speaking, the support surface is increased and the overall stability is better.

Therefore, the inter-column support body 100 of the present invention is X-shaped, or called scissor-shaped. At least two inclined parallel support rods 1 are arranged on both sides of the X-shaped inter-column support body 100, and two adjacent inclined parallel support rods 1 are connected and fixed by a tie rod connection assembly 2.

The tie rod connection assembly 2 is provided with multiple groups, which are arranged along two sides between two support rods 1 arranged obliquely and parallelly on each side, and connect the two support rods 1 on the same side. The tie rod connection assembly 2 is evenly arranged along the length direction of the support rod 1. The tie rod connection assembly 2 is connected and fixed to the two support rods 1 arranged obliquely and parallelly on each side of the X-shaped inter-column support body 100 along both ends by bolts 7.

It is easy to understand that the two sides here refer to the two sides of the inter-column support body 100 crossing in an X shape, wherein the support rod 1 on one side is tilted from the upper left to the lower right, and the support rod 1 on the other side is tilted from the upper right to the lower left, and the support rods 1 on both sides cross in an X shape along the middle position.

It should be understood that the two sides here refer to the left and right side surfaces of the two support rods 1 on each side that are arranged in an inclined and parallel manner.

The tie rod connection assembly 2 is symmetrically arranged along the left and right sides of the two inclined parallel support rods 1 on each side. This ensures that the support force is evenly distributed on both sides of the support rod 1, avoiding the situation where the support point is concentrated on one side to cause structural instability; at the same time, it can also increase the stability of the overall structure, especially when it is subjected to external loads or lateral forces, it can effectively prevent the structure from tilting or overturning; and it can increase the bearing capacity of the support structure so that it can better cope with the effects of vertical loads and lateral loads.

In some embodiments, the support rod 1 is generally made of channel steel, and the notches of two adjacent channel steels on the same side that are arranged in an inclined and parallel manner are relatively buckled.

The tie rod connection assembly 2 is symmetrically arranged along the two sides of the channel steel. The tie rod connection assembly 2 connects the two sides of two adjacent channel steels arranged in an inclined and parallel manner on the same side through bolts 7.

This type of prefabricated construction greatly reduces the installation time of column supports, shortens the construction schedule, and improves construction efficiency. In addition, compared with welding connections, bolt connections have less thermal impact and more uniform stress distribution.

Referring to Figure 1, the two support rods 1 on one side of the X-shaped inter-column support body 100 are disconnected along the middle intersection of the support rods 1 on both sides, and the two support rods 1 arranged obliquely and parallel to the other side at the disconnected position are connected and fixed by a middle connecting plate 3 and bolts 7.

This design facilitates the installation of the two support rods 1 on both sides of the X-shaped inter-column support body 100, allowing necessary adjustments and maintenance to be performed in the central area while maintaining the overall integrity of the structure.

In some embodiments, the middle connecting plate 3 is a hexagonal steel plate, and two hexagonal steel plates are provided, which are symmetrically arranged on the outside of the two supporting rods 1 on the other side. The middle connecting plate 3 adopts a hexagonal design, which has the following advantages: 1) It has good rigidity and stability in shape, and can effectively resist the pressure and bending force on the inter-column support, thereby improving the overall stability of the supporting structure. 2) The design of the hexagonal steel plate can also effectively bear vertical and horizontal loads, play a role of stable support in the inter-column support, and help improve the bearing capacity of the supporting structure. 3) The hexagonal steel plate has a good strength-to-weight ratio, which can reduce the overall weight of the supporting structure while providing sufficient bearing capacity, thereby reducing the cost of the structure and the difficulty of construction. 4) The shape design of the hexagonal steel plate is relatively compact, which can make more effective use of materials, reduce material waste, improve material utilization, and reduce costs.

Referring to FIG. 1 , a connecting hole is provided in the middle of each of the two hexagonal steel plates, which is used to connect the two support rods 1 on the other side through a bolt 7 . Two connecting holes are correspondingly provided on the upper and lower sides of the two hexagonal steel plates, which are used to connect the two support rods 1 disconnected along the middle intersection on one side through a bolt 7 .

This connection method is easy to install and is easier to maintain and replace when the support rod 1 on one side is damaged or aged, thereby reducing the cost and complexity of long-term maintenance.

In some embodiments, referring to FIGS. 1 to 4 , the tie rod connection assembly 2 includes a main connection plate 201 and two end connection plates 202 , and the length of the main connection plate 201 is much greater than the length of the end connection plates 202 .

In the present invention, the main connecting plate 201 is horizontally arranged between two inclined and parallel supporting rods 1 on each side of the X-shaped inter-column supporting body 100, and the two end connecting plates 202 are symmetrically arranged on both sides below the main connecting plate 201, and are correspondingly arranged above the two supporting rods 1. One side of the two end connecting plates 202 abuts against the supporting rod 1 along the bottom, and the other side abuts against the main connecting plate 201 along the top. The two end connecting plates 202 are connected and fixed to one of the supporting rods 1 along the side abutting against the supporting rod 1, and are connected and fixed to the main connecting plate 201 along the side abutting against the main connecting plate 201.

It should be understood that the horizontal direction here refers to the direction of the two support rods 1 that are arranged horizontally and vertically in parallel and inclined.

It should be understood that the connection here refers to bolt connection, which is easy to install and disassemble, simplifies the installation process, improves construction efficiency, and compared with welding connection, bolt connection reduces thermal impact and makes stress distribution more uniform.

In the present invention, according to the construction requirements and taking into account the construction errors, when the main connecting plate 201 is installed, a certain distance needs to be reserved between its two ends and the two support rods 1 arranged in an inclined and parallel manner. Otherwise, the connection position between the main connecting plate 201 and the support rod 1 will not be sufficient to install bolts with sufficient bearing capacity for connection. Therefore, it is necessary to respectively set an end connecting plate 202 at both ends of the main connecting plate 201, and use the end connecting plate 202 to first connect with the support rod 1, and then connect the main connecting plate 201 with the end connecting plate 202 to improve the stability of the connection.

Continuing to refer to Figures 2 to 4, two bolt holes are provided on the left and right sides of the two end connecting plates 202 corresponding to the support rods 1 and the main connecting plate 201. One side of the two end connecting plates 202 is connected and fixed to one of the support rods 1 by a group of bolts 7, and the other side is connected and fixed to the main connecting plate 201 by another group of bolts 7.

Continuing to refer to Figures 1 to 4, the main connecting plate 201 is an angle steel, which is arranged back to back on both sides of two support rods 1 arranged obliquely and parallel on each side. The main connecting plate 201 is bolted and fixed to the two support rods 1 through one side surface of the angle steel through two end connecting plates 202.

In some embodiments, the end connecting plate 202 is a rectangular steel plate, half of which is arranged below one side of the angle steel and fixed to the angle steel by bolts 7, and the other half of which is arranged above the support rod 1 and fixed to the support rod 1 by bolts 7.

In some embodiments, referring to FIG. 1 , the angle steel is symmetrically arranged along both sides of the channel steel of the support rod 1 , and the two rectangular steel plates are also symmetrically arranged along both sides of the channel steel of the support rod 1 . The angle steel is connected and fixed to two adjacent channel steels through bolts 7 along its two ends through the two rectangular steel plates.

1 and 5 to 7 , the energy dissipation connection assembly 4 is disposed on the top of two support rods 1 arranged in an inclined and parallel manner on each side, and one end thereof is connected and fixed to the support rods 1 .

The function of the energy dissipation connection assembly 4 is similar to that of a damper used in existing buildings. It is connected to the top of the support rod 1 and can dissipate part of the earthquake energy.

In some embodiments, the energy-absorbing connection component 4 includes two outer steel plates 401 and two embedded solid viscoelastic material layers 403. The energy-absorbing connection component 4 is formed by alternatingly stacking the two outer steel plates 401 and the two embedded solid viscoelastic material layers 403, that is, the two outer steel plates 401 are stacked, the two embedded solid viscoelastic material layers 403 are embedded between the two outer steel plates 401, and the two embedded solid viscoelastic material layers 403 are separated, and a certain gap is reserved to facilitate the insertion of the end self-resetting component 5.

The two embedded solid viscoelastic material layers 403 of the energy-absorbing connecting component 4 are respectively connected to one of the outer steel plates 401 along the other end of the energy-absorbing connecting component 4, and the gap reserved between the two embedded solid viscoelastic material layers 403 is consistent with the thickness of the end self-resetting component 5, so as to facilitate the tight installation of the end self-resetting component 5.

In the present invention, the embedded solid viscoelastic material layer is generally selected from polyurethane, nitrile rubber, etc. By setting the embedded solid viscoelastic material layer, the following advantages are achieved: 1) The embedded solid viscoelastic material layer can absorb energy when the structure is subjected to external impact or vibration, and convert it into heat energy or other forms of energy dissipation, thereby reducing the impact or vibration on the structure, which helps to reduce the stress and deformation of the structure and extend the service life of the structure. 2) The embedded solid viscoelastic material layer can slow down the speed of the impact or vibration of the structure, reduce the amplitude and frequency of the vibration, thereby reducing the impact of the vibration on the structure and the surrounding environment, which helps to improve the stability and comfort of the structure. 3) The embedded solid viscoelastic material layer can reduce the damage to the structure itself caused by the impact or vibration of the structure. By absorbing and dispersing energy, they can reduce the stress concentration in the structure, reduce the fatigue and damage risk of the structure, and extend the service life of the structure. 4) The energy dissipation capacity of the embedded solid viscoelastic material layer can improve the seismic resistance of the structure, reduce the degree of damage to the structure caused by earthquakes, and improve the safety and reliability of the structure. 5) By reducing vibration and noise transmission, the embedded solid viscoelastic material layer can improve the comfort of the structure and improve the quality of the working or living environment of personnel inside the structure.

The length of the two embedded solid viscoelastic material layers 403 is shorter than the length of the outer steel plate 401 .

An embedded solid viscoelastic material layer 403 is provided at a partially overlapping position of the two outer steel plates 401 of the energy-absorbing connection assembly 4, so as to facilitate the connection of the end self-resetting component 5 for energy dissipation, and no embedded solid viscoelastic material layer 403 is provided at another partially overlapping position of the two outer steel plates 401 of the energy-absorbing connection assembly 4, so as to facilitate the connection of the support rod 1 by bolts.

In the present invention, since the other overlapping positions of the two outer steel plates 401 of the energy-absorbing connection assembly 4 do not have an embedded solid viscoelastic material layer 403, that is, part of the length of the two outer steel plates 401 is not connected and fixed to the embedded solid viscoelastic material layer 403, an embedded steel pad 402 is inserted along the length position for filling. The thickness of the embedded steel pad 402 is the same as the thickness of each embedded solid viscoelastic material layer 403. Two embedded steel pads 402 are also inserted, and a gap the same as the two embedded solid viscoelastic material layers 403 is reserved between the two embedded steel pads 402 to facilitate the insertion of the support rod 1 into the gap and to connect and fix it to the two adjacent outer steel plates 401 by bolts 7.

The embedded steel pad 402 fills the gap between the support rod 1 and the two outer steel plates 401, so as to tightly connect the support rod 1 and prevent it from falling off.

In the present invention, the embedded solid viscoelastic material layer 403 is connected to the outer steel plate 401 by vulcanization. The end self-resetting member 5 is also connected to the two adjacent embedded solid viscoelastic material layers 403 by vulcanization in the gap reserved by the two embedded solid viscoelastic material layers 403. The embedded solid viscoelastic material layer 403 has good shock and vibration reduction performance, and can be tightly combined with the steel plate through vulcanization connection, so that when the structure is subjected to external vibration or impact, it can absorb and disperse energy, reduce the degree of vibration transmission to the structure, and improve the seismic performance and comfort of the structure.

In some embodiments, the outer steel plate 401 is a channel steel, and two channel steels are arranged on the inner and outer sides of the channel steel of the support rod 1, wherein one of the two channel steels is slightly smaller than the channel steel of the support rod 1, and is stacked on the inner side of the channel steel along the same direction as the channel steel of the support rod 1, and the other channel steel is slightly larger than the channel steel of the support rod 1, and is stacked on the outer side of the channel steel along the same direction as the channel steel of the support rod 1.

Referring to Fig. 1, one end of the two channel steels is overlapped along the inner and outer sides of the channel steel of the support rod 1, and multiple groups of bolt holes are provided along the overlapped positions of the two channel steels with the channel steel of the support rod 1, so as to facilitate the connection of the support rod 1 with bolts 7. The other ends of the two channel steels are provided with an embedded solid viscoelastic material layer 403 along the opposite side thereof, and the embedded solid viscoelastic material layer 403 is U-shaped, and a U-shaped gap is reserved between the two U-shaped embedded solid viscoelastic material layers 403, and the end self-resetting member 5 is inserted into the U-shaped gap and fixed to the adjacent embedded solid viscoelastic material layer 403 by vulcanization.

In this embodiment, both the connection between the channel steel and the embedded solid viscoelastic material layer 403 and the connection between the end self-resetting member 5 and the embedded solid viscoelastic material layer 403 are connected by vulcanization.

In the present invention, the embedded solid viscoelastic material layer 403 and the adjacent structure are connected by vulcanization, which can effectively reduce the noise generated by the mechanical equipment or structure during operation, prevent the propagation of vibration in the structure, and reduce the interference with the surrounding environment and other equipment. Vulcanization connection usually has good durability and stability, is easy to install, has low maintenance cost, and can reduce the maintenance workload and cost of the structure.

In some embodiments, the embedded steel pad 402 is a channel steel, and two channel steels are provided. The two channel steels are correspondingly inserted between the support rod 1 and one of the outer steel plates 401, and are connected and fixed by bolts 7.

1 , 8 and 9 , the end self-resetting member 5 is disposed on the top of the energy-consuming connecting assembly 4 , and one end of the end self-resetting member 5 is connected and fixed to the other end of the energy-consuming connecting assembly 4 .

The end self-resetting member 5 of the present invention is made of shape memory alloy, and its shape is the same as that of the support rod 1 , that is, the same as that of the channel steel of the support rod 1 .

The end self-resetting member 5 is arranged on the top of the energy-absorbing connection assembly as a supporting rod. The end self-resetting member works together with the energy-absorbing connection assembly similar to a damper to dissipate the energy generated by external forces such as earthquakes and enhance the stability and reliability of the overall structure.

In some embodiments, the end self-resetting member 5 is a U-shaped member.

The end self-resetting component 5 of the present invention will deform after consuming energy. Since the end self-resetting component 5 is made of shape memory alloy, it will automatically return to its original shape afterwards, thereby improving the recovery ability of the structure after an earthquake, avoiding stability problems caused by deformation of the structure, and reducing damage.

1 , 10 and 11 , the end connecting members 6 are provided at both ends of the support rod 1 , and are connected and fixed to the other end of the end self-resetting member 5 or the support rod 1 at both ends of the support rod 1 .

The self-resetting assembled inter-column support of the present invention is connected and fixed to two adjacent columns by bolts 7 through an end connecting member 6 arranged at its end.

The end connection member 6 includes an end connection plate, and the surface of the end connection plate is wrapped with a layer of carbon fiber. Since the column foot bearing capacity must not be less than 1.2 times the plastic yield bearing capacity of the column section, the present invention uses an end connection member 6 with an end connection plate wrapped with carbon fiber to improve the bearing capacity of the structure and enhance the reliability and stability of the structure.

In the present invention, wrapping a layer of carbon fiber on the surface of the end connection plate has the following advantages: 1) Carbon fiber has excellent strength and rigidity. Wrapping it around the end connection plate can enhance the bearing capacity of the connection part, thereby improving the stability and safety of the overall structure. 2) Carbon fiber has excellent corrosion resistance. Using it as a wrapping material can effectively prevent the end connection plate from being affected by corrosion and extend the service life of the connection part. 3) Carbon fiber has a lower density than metal materials. Therefore, wrapping the end connection plate with carbon fiber can reduce the weight of the structure, reduce the dead weight of the structure, help save materials and reduce construction costs. 4) Carbon fiber has good seismic resistance and can effectively absorb and disperse the energy generated during an earthquake, reduce the vibration impact on the structure, and improve the seismic resistance of the structure. 5) Wrapping the end connection plate with carbon fiber can simplify the construction process to a certain extent, and at the same time, no additional maintenance is required, which can reduce maintenance costs.

Continuing to refer to Figures 10 and 11, the end connecting plate of the present invention is a pentagonal steel plate, which is provided with three bolt holes arranged in a triangular shape, wherein two bolt holes arranged corresponding to the bottom edge of the pentagonal steel plate are connected and fixed to the end self-resetting member 5 and the support rod 1 by bolts 7, and one bolt hole arranged corresponding to the two oblique sides of the pentagonal steel plate is used for connection with the adjacent column by bolts 7.

The energy dissipation principle of the self-resetting assembled column support of the present invention is as follows:

When the factory building structure is hit by an earthquake, the energy is transferred to the inter-column support. Since the end connection plate at the column foot is covered with carbon fiber, its bearing capacity is enhanced and it is not damaged. Afterwards, the energy is transferred to the end self-resetting component, which is deformed and slides downward along the support rod. However, due to the existence of the energy-absorbing connection assembly, the energy-absorbing connection assembly dissipates the earthquake energy. When the energy is transferred to the inter-column support body below, it can no longer damage the inter-column support body. After the earthquake, the end self-resetting component returns to its original shape and continues to play its original role.

Although several specific implementation details are included in the above discussion, these should not be construed as limiting the scope of the present invention.
