In the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
The implementation of the present invention will be described in detail with reference to the preferred embodiments.
As shown in fig. 1 to 11, the present invention provides a self-resetting assembled inter-column support, which is particularly suitable for a heavy industrial factory building, is arranged between two adjacent columns of the heavy industrial factory building, and is used as a support member of the heavy industrial factory building. The assembly type design of the self-resetting assembly type inter-column support can improve the construction efficiency of the whole structure, and can recover the deformation generated by the structure after the earthquake action.
Specifically, the self-resetting fabricated inter-column support includes an inter-column support body 100, a tie-bar connection assembly 2, an energy consuming 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 plant, improve the lateral rigidity and transfer the longitudinal horizontal force, the heavy industry plant needs to adopt double-piece inter-column support. The double-piece column support means that the two sides are used as fulcra to bear the weight of the structure, so that the supporting surface is relatively increased, and the overall stability is better.
Thus, the inter-column support body 100 of the present invention is X-shaped, or so-called scissor-shaped. At least two support rods 1 which are obliquely arranged in parallel are arranged on two sides of the X-shaped column support body 100, and two adjacent support rods 1 which are obliquely arranged in parallel are fixedly connected through a tie rod connecting assembly 2.
The tie rod connecting assembly 2 is provided with a plurality of groups, is arranged between two support rods 1 which are obliquely and parallelly arranged on each side along two sides, and is connected with the two support rods 1 on the same side. The tie bar connecting assemblies 2 are uniformly arranged along the length direction of the support bar 1. The tie bar connection assembly 2 is fixedly connected with two support bars 1 which are obliquely arranged in parallel along both ends and each side of the X-shaped inter-column support body 100 through bolts 7.
It is to be easily understood that the two sides herein refer to the two sides of the inter-column support body 100 crossing in an X-shape, wherein one side support bar 1 is disposed obliquely from top left to bottom right, the other side support bar 1 is disposed obliquely from top right to bottom left, and the two side support bars 1 cross in an X-shape along the middle position.
It should be understood that the two sides herein refer to the left and right sides of the support bar 1, each side of which is provided with two support bars arranged in an inclined parallel manner.
The tie bar connecting assemblies 2 are symmetrically arranged along the left and right sides of each side of two support bars 1 arranged in an inclined parallel manner. Therefore, the supporting force can be ensured to be uniformly distributed on the two sides of the supporting rod piece 1, and the condition that the structure is unstable due to the fact that the supporting point is concentrated on one side is avoided; meanwhile, the stability of the whole structure can be improved, and the structure can be effectively prevented from tilting or turning over when the whole structure is particularly subjected to external load or lateral force; and the bearing capacity of the supporting structure can be increased, so that the supporting structure can better cope with the effects of vertical load and transverse load.
In some embodiments, the support rod 1 is generally made of channel steel, and two adjacent channel steel slots arranged in an inclined parallel manner on the same side are oppositely buckled.
The tie bar connecting assemblies 2 are symmetrically arranged along two side edges of the channel steel, and the tie bar connecting assemblies 2 are connected with two side edges of two adjacent channel steel which are obliquely and parallelly arranged on the same side through bolts 7.
The assembly type construction greatly reduces the installation time of the inter-column support, shortens the construction progress and improves the construction efficiency. And the bolt connection has smaller thermal influence and more uniform stress distribution compared with the welded connection.
Referring to fig. 1, two support bars 1 on one side of an x-shaped inter-column support body 100 are broken along the middle junction position of the support bars 1 on both sides, and the two support bars 1 arranged in an inclined parallel manner on the other side at the broken position are connected and fixed by a middle connecting plate 3 and bolts 7.
This design facilitates the installation of two support bars 1 on either side of the X-shaped inter-column support body 100, allowing the necessary adjustment and maintenance 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 arranged on the outer sides of the two support rods 1 symmetrically arranged on the other side. The middle connecting plate 3 adopts a hexagonal design, and has the following advantages: 1) The support structure has good rigidity and stability in shape, can effectively resist the pressure and bending force born by the inter-column support, and improves the overall stability of the support structure. 2) The design of hexagonal steel sheet can also bear vertical load and horizontal load effectively, plays the effect of firm support in the column-to-column support, helps improving bearing capacity of bearing structure. 3) The hexagonal steel plate has a good strength-weight ratio, can provide enough bearing capacity, and simultaneously lighten the whole weight of the supporting structure, and reduces the cost and construction difficulty of the structure. 4) The hexagonal steel plate has a relatively compact shape design, can more effectively utilize materials, reduces the waste of the materials, improves the utilization rate of the materials and reduces the cost.
Referring to fig. 1, the middle parts of two hexagonal steel plates are respectively provided with a connecting hole for connecting two support rods 1 at the other side through bolts 7, and the upper and lower sides of the two hexagonal steel plates are respectively and correspondingly provided with two connecting holes for connecting two support rods 1 with one side disconnected along the middle part intersection position through bolts 7.
This connection is easy to install and also makes maintenance and replacement easier when the support bar 1 on one side is damaged or aged, reducing the cost and complexity of long-term maintenance.
In some embodiments, referring to fig. 1-4, the tie-bar 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 invention, a main connecting plate 201 is transversely arranged between two support rods 1 which are obliquely arranged in parallel on each side of an X-shaped column support body 100, two end connecting plates 202 are symmetrically arranged on two sides below the main connecting plate 201 and correspondingly arranged above the two support rods 1, one side of each end connecting plate 202 is abutted with the support rod 1 along the lower side thereof, the other side is abutted with the main connecting plate 201 along the upper side thereof, and the two end connecting plates 202 are fixedly connected with one support rod 1 along the side abutted with the support rod 1 and fixedly connected with the main connecting plate 201 along the side abutted with the main connecting plate 201.
It should be understood that the lateral direction herein refers to the direction of two support bars 1 arranged in an inclined parallel manner, horizontally and vertically.
It should be understood that the connection herein refers to a bolted connection, which is convenient to install and detach, simplifies the installation process, improves the construction efficiency, and reduces the thermal influence relative to a welded connection, resulting in more uniform stress distribution.
In the invention, according to construction requirements, construction errors are considered, when the main connecting plate 201 is installed, a certain distance is reserved between two support rods 1 which are obliquely arranged in parallel, otherwise, the connection position of the main connecting plate 201 and the support rods 1 is insufficient to install bolts for providing enough bearing capacity for connection, so that one end connecting plate 202 is required to be arranged at two ends of the main connecting plate 201, the end connecting plate 202 is used for connecting the main connecting plate 201 with the support rods 1 firstly, and then the main connecting plate 201 is connected with the end connecting plate 202, thereby improving the connection stability.
With continued reference to fig. 2 to 4, two bolt holes are formed on the left and right sides of the two end connecting plates 202 corresponding to the support rod pieces 1 and the main connecting plate 201, one side of the two end connecting plates 202 is connected and fixed with one support rod piece 1 through one set of bolts 7, and the other side is connected and fixed with the main connecting plate 201 through the other set of bolts 7.
With continued reference to fig. 1 to 4, the main connecting plate 201 is an angle steel, and is disposed back-to-back on two sides of two support rods 1 disposed in parallel and inclined on each side, and the main connecting plate 201 is connected and fixed with two support rods 1 through bolts of two end connecting plates 202 through one side surface of the angle steel.
