Modularized steel structure force-bearing adjustable support and application method thereof

Abstract

The invention relates to a modularized steel structure force-bearing adjustable support and an application method thereof. The modularized steel structure force-bearing adjustable support comprises a tension-compression conversion mechanism, a fixed constraint piece, a first core plate and a second core plate. The first ends of the first core board and the second core board in the length direction are connected with the tension-compression conversion mechanism, and the second ends of the first core board and the second core board in the length direction are fixedly connected with the fixing restraining pieces. When the support is pulled or pressed, the pulling and pressing conversion mechanism can drive the first core plate and the second core plate to move oppositely in the first direction, one of the first core plate and the second core plate is pulled, and the other one is pressed. Parts of the core plates yield to dissipate energy for earthquakes, energy dissipation under the action of large earthquakes is facilitated, and the other parts of the core plates are pressed to be bent, so that the bearing capacity of the core plates is rapidly reduced, and the overall bearing capacity is degraded. Meanwhile, the effective length of the core board can be adjusted through the distance between the two sets of jacking pieces in the first direction, and therefore the bearing capacity of the core board can be adjusted independently of the rigidity.

Description

Technical Field

[0001] The present invention relates to the technical field of modular steel structure construction, and in particular to a modular steel structure load-bearing adjustable support and an application method thereof. Background Art

[0002] The introduction of support components in high-rise modular structures can effectively improve their lateral resistance and energy dissipation capacity. Traditional supports mainly include ordinary supports and buckling-restrained braces (BRBs). Among them, ordinary supports buckle when under compression and their bearing capacity drops rapidly, and their bearing capacity and energy dissipation capacity are relatively poor; BRB supports are restraining structures added to the outside of ordinary supports to restrain the core panels. The restraining structure can prevent the core panels from buckling under compression, so that the core panels can reach the yield stage and dissipate earthquake energy when under compression and tension under earthquake action. However, the core panels of BRB supports will enter the strengthening stage from the yield stage during compression and tension, and their bearing capacity will further increase, which will lead to an increase in the internal force of the columns connected to the BRB supports. Since the modular columns in modular structures are smaller in size and the force transmission at the connection nodes is concentrated, the continuous increase in the resistance of the support in the nonlinear stage will increase the node force and reduce the ductility of the modular columns, resulting in insufficient structural resistance and energy dissipation capacity.

[0003] Therefore, there is an urgent need for a new modular load-bearing adjustable support that can reduce the stress level of structural columns and connection nodes under the action of a large earthquake (i.e., an earthquake). Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a modular steel structure load-bearing adjustable support and an application method thereof, which solves the problem that ordinary supports in the prior art have poor energy dissipation capacity and the continuous increase in the bearing capacity of BRB supports during major earthquakes may lead to easy damage to modular structural columns and their connection nodes.

[0006] (II) Technical solution

[0007] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0019] According to the present invention, it also includes a linkage component;

[0020] The linkage assembly connects the first force transmission member and the second force transmission member;

[0021] The linkage assembly is used to drive the second force transmission member to synchronously move along the first direction toward a direction away from the first force transmission member when the first force transmission member bears the pulling force in the first direction and moves along the first direction toward a direction away from the second force transmission member; or,

[0022] The linkage assembly is used to drive the second force transmission member to synchronously move along the first direction toward the direction close to the first force transmission member when the first force transmission member bears the pressure in the first direction and moves along the first direction toward the direction close to the second force transmission member.

[0023] According to the present invention, the tension-compression conversion mechanism further comprises a fixing member;

[0025] The linkage assembly includes a gear, a first rack and a second rack;

[0026] The fixed member is rotatably connected to the horizontally oriented gear;

[0027] The first rack extending along the first direction is fixed on the first force transmission member, and the second rack extending along the first direction is fixed on the second force transmission member; the first rack and the corresponding second rack are meshed at upper and lower sides of the corresponding gear.

[0028] According to the present invention, a horizontally oriented connecting rod is fixed on the fixing member, and the gear is sleeved on the connecting rod and can rotate relative to the connecting rod;

[0030] The fixing restraint is provided with a connection hole for allowing the end of the connecting rod to extend out, and the end of the connecting rod extending out of the fixing restraint is threadedly connected with a nut capable of abutting against the fixing restraint.

[0031] According to the present invention, the longitudinal section of the fixed constraint is C-shaped, the fixed constraint extends along the first direction, the fixed constraint can be sleeved on both sides of the first core board and the second core board, and the open end of the fixed constraint is fixedly connected to the fixing member;

When the tension-compression conversion mechanism is compressed under the action of an earthquake, the first core plate can be compressed and buckled, and the second core plate can be pulled into the yield stage. Therefore, when the tension-compression conversion mechanism of the modular steel structure load-bearing adjustable support is pulled and compressed under the action of an earthquake, part of the core plate can enter the yield stage and consume earthquake energy, effectively improving the material utilization rate of the core plate, which is beneficial to energy consumption under the action of a large earthquake, and another part of the core plate is compressed and buckled without continuing to bear the load, so that the overall load-bearing capacity of the modular steel structure load-bearing adjustable support is degraded, and the overhanging connection section used to connect the beams and columns is avoided from being instable, and the force applied by the modular steel structure load-bearing adjustable support to the connected beams and columns is avoided, effectively reducing the impact on the connected beams and columns.

[0040] Furthermore, when the spacing between the two groups of pressure members along the first direction is adjusted, the effective length of the first core plate and the second core plate participating in the load-bearing along the first direction can be changed, so that the peak load-bearing capacity of the first core plate and the second core plate along the first direction can be changed without affecting the stiffness.

[0059] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific embodiments. Figure 1 The orientation is reference 1.

[0060] See also Figure 1-8 A modular steel structure load-bearing adjustable support is proposed in an embodiment of the present invention, including a tension-compression conversion mechanism 3, a fixed constraint 4, a first core plate 1 and a second core plate 2.

[0061] The tension-compression conversion mechanism 3 and the fixed constraint 4 can respectively connect adjacent columns and beams. The first core board 1 and the second core board 2 both extend along the first direction A. The first ends of the first core board 1 and the second core board 2 in the length direction are connected to the tension-compression conversion mechanism 3, and the second ends of the first core board 1 and the second core board 2 in the length direction are both fixedly connected to the fixed constraint 4.

[0062] When the tension-compression conversion mechanism 3 is pulled or compressed, it can drive the first core board 1 and the second core board 2 to move in opposite directions along the first direction A, so that one of the first core board 1 and the second core board 2 is pulled and the other is compressed.

[0063] It should be noted that the tension-compression conversion mechanism 3 and the fixed constraint 4 are used to connect adjacent beams and columns respectively, so the tension-compression conversion mechanism 3 can bear the tension F1 and pressure F2 under the action of an earthquake. When the first core board 1 and the second core board 2 bear a force in the first direction A toward the first end of themselves, the second ends of the first core board 1 and the second core board 2 are away from the fixed constraint 4 and bear the tension F1. When the first core board 1 and the second core board 2 bear a force in the first direction A toward the second end of themselves, the second ends of the first core board 1 and the second core board 2 are squeezed onto the fixed constraint 4 and bear the pressure F2. Wherein, the first direction A refers to the overall extension direction of the tension-compression conversion device.

[0064] Furthermore, when the support is under tension or compression, the tension-compression conversion mechanism 3 is correspondingly under tension or compression. The supporting method of the modular steel structure load-bearing adjustable support is as follows:

[0065] See also Figure 6 When the tension-compression conversion mechanism 3 bears the tension F1 in the first direction A under the action of an earthquake, it can drive the first core board 1 and the second core board 2 to move simultaneously in the first direction A in opposite directions: the first core board 1 moves along the first direction A toward its first end, and the second core board 2 moves along the first direction A toward its second end, so that the first core board 1 yields under tension and the second core board 2 buckles under compression.

[0066] See also Figure 7 When the tension-compression conversion mechanism 3 bears the pressure F2 in the first direction A under the action of an earthquake, it can drive the first core plate 1 and the second core plate 2 to move simultaneously in opposite directions along the first direction A: the first core plate 1 moves along the first direction A toward its second end, and the second core plate 2 moves along the second direction toward its first end, so that the first core plate 1 is compressed and buckled and the second core plate 2 is tensile and yielded.

[0067] Thus, the load-bearing adjustable support of the modular steel structure, when the tension-compression conversion mechanism 3 is pulled under the action of an earthquake, the first core plate 1 can be pulled into the yield stage, and the second core plate 2 can be compressed and buckled. When the tension-compression conversion mechanism 3 is compressed under the action of an earthquake, the first core plate 1 can be compressed and buckled, and the second core plate 2 can be pulled and enter the yield stage. Therefore, when the tension-compression conversion mechanism 3 of the load-bearing adjustable support of the modular steel structure is pulled and compressed under the action of an earthquake, part of the core plate can enter the yield stage and consume earthquake energy, effectively improving the material utilization rate of the core plate, which is conducive to energy consumption under the action of a large earthquake, and another part of the core plate is compressed and buckled without continuing to bear the load, so that the overall load-bearing capacity of the load-bearing adjustable support of the modular steel structure is degraded, avoiding the instability of the overhanging connection section used for the modular steel structure, and avoiding increasing the force applied by the load-bearing adjustable support of the modular steel structure to the connected beams and columns, effectively reducing the impact on the connected beams and columns.

[0068] See also Figure 3 and 4 Furthermore, the tension-compression conversion mechanism 3 includes a first force transmission member 32 and a second force transmission member 33 .

[0069] The first force transmission member 32 can be connected to a column or a beam, and bear the tensile force F1 and the compressive force F2 under the action of an earthquake. The first force transmission member 32 and the second force transmission member 33 can be connected to approach toward each other or move away from each other simultaneously along the first direction A. The first force transmission member 32 is fixedly connected to the first end of the first core board 1, and the second force transmission member 33 is fixedly connected to the first end of the second core board 2.

[0070] When the first force transmission member 32 is pulled or compressed, the first force transmission member 32 and the second force transmission member 33 can move toward or away from each other simultaneously along the first direction A to drive the first core board 1 and the second core board 2 to move in opposite directions along the first direction A.

[0071] Specifically, the longitudinal sections of the first force transmission member 32 and the second force transmission member 33 are both C-shaped, the openings of the first force transmission member 32 and the second force transmission member 33 are opposite, the first force transmission member 32 is sleeved outside the second force transmission member 33, and the two can be connected to approach each other or move away from each other at the same time along the first direction A. The first core board 1 fixed on the two plug-in parts of the first force transmission member 32 is symmetrically arranged on the upper and lower sides of the second core board 2 fixed on the main body of the second force transmission member 33, and the sum of the bearing capacity of the first core board 1 is consistent with the bearing capacity of the second core board 2.

[0072] Therefore, when the load-adjustable support of the modular steel structure bears the tension F1 and pressure F2 under the action of an earthquake, the tensile bearing capacity of the first core panel 1 is symmetrical with the compressive bearing capacity of the second core panel 2, and the compressive bearing capacity of the first core panel 1 is symmetrical with the tensile bearing capacity of the second core panel 2, so that the force of the tension-compression conversion mechanism 3 is balanced.

[0073] Specifically, the first core board 1 and the second core board 2 are arranged as follows:

[0074] At least one and the same number of first core boards 1 are fixedly connected to the two plug-in parts of the first force transmission member 32, and at least one second core board 2 is fixedly connected to the second force transmission member 33. The first core boards 1 fixed to the two plug-in parts of the first force transmission member 32 are symmetrically arranged on the upper and lower sides of the second core board 2 fixed to the main body of the second force transmission member 33, and the sum of the bearing capacity of the first core board 1 is consistent with the bearing capacity of the second core board 2.

[0075] When there are multiple first core boards 1 fixed on a plug-in portion, the multiple first core boards 1 are arranged in parallel vertically and / or horizontally. When there are multiple second core boards 2, the multiple second core boards 2 are arranged in parallel vertically and / or horizontally.

[0076] Therefore, the modular steel structure load-bearing adjustable support can arrange the number and arrangement of the first core panel 1 and the second core panel 2 according to actual needs, ensuring that the tensile and compressive bearing capacities of the modular steel structure load-bearing adjustable support are symmetrical, and the force of the tension-compression conversion mechanism 3 is balanced.

[0077] It should be noted that the fixed connection defined in this embodiment refers to a relatively fixed position during operation, at least without any relative movement in the first direction A, rather than a non-detachable connection.

[0078] Preferably, see Figure 5 The number of first core boards 1 on each plug-in portion of the second core board 2 and the first force transmission member 32 is one. The two first core boards 1 on the two plug-in portions fixed on the first force transmission member 32 are symmetrically arranged on the upper and lower sides of the second core board 2 fixed on the second force transmission member 33 to simplify the structure and facilitate processing.

[0079] See also Figure 8 , the thickness D of the first core board 1 and the second core board 2 is consistent, and the sum of the widths E of the two first core boards 1 is consistent with the width E of the second core board 2, so that the sum of the stiffness of the two first core boards 1 is consistent with the stiffness of the second core board 2, and the sum of the tension F1 borne by the two first core boards 1 is consistent with the pressure F2 borne by the second core board 2, and the sum of the pressure F2 borne by the two first core boards 1 is consistent with the tension F1 borne by the second core board 2, that is, to ensure that the tension and compression stiffness of the two core boards of the load-adjustable support of this modular steel structure are symmetrical, the tensile bearing capacity and compressive bearing capacity of the two core boards are symmetrical, and further the force balance of the tension-compression conversion mechanism 3 is achieved.

[0080] Optionally, the first end and the second end of the first core board 1 and the second core board 2 are both welded to the fixing member 31 and the fixing restraining member 4 to facilitate processing.

[0081] Preferably, the first core plate 1 and the second core plate 2 are both steel plates.

[0082] For further information, see Figure 3 and 4 The modular steel structure load-bearing adjustable support also includes a linkage assembly 5 for driving the first force transmission member 32 and the second force transmission member 33 to move toward each other or away from each other simultaneously along the first direction A.

[0083] The linkage assembly 5 connects the first force transmission member 32 and the second force transmission member 33 .

[0084] The linkage assembly 5 is used to drive the second force transmission member 33 to move synchronously along the first direction A toward a direction away from the first force transmission member 32 when the first force transmission member 32 bears the pulling force F1 in the first direction A and moves along the first direction A toward a direction away from the second force transmission member 33; or,

[0085] The linkage assembly 5 is used to drive the second force transmission member 33 to synchronously move along the first direction A toward the first force transmission member 32 when the first force transmission member 32 bears the pressure F2 in the first direction A and moves toward the second force transmission member 33 .

[0086] In this way, the synchronization of the movement of the first force transmission member 32 and the second force transmission member 33 can be ensured.

[0087] Furthermore, the tension-compression conversion mechanism 3 also includes a fixing member 31 .

[0088] The fixing member 31 is fixedly connected to the fixing restraining member 4 to define the position of the fixing member 31. The fixing member 31 is provided with a first socket 311 and a second socket 312 arranged vertically, and the first socket 311 and the second socket 312 are both connected along the first direction A.

[0089] The first force transmission member 32 and the second force transmission member 33 are both movably plugged into the first socket 311 and the second socket 312 along the first direction A, so as to ensure the accuracy and stability of the first force transmission member 32 and the second force transmission member 33 approaching or moving away from each other, and ensure the accuracy and stability of the first core board 1 and the second core board 2 moving in opposite directions along the first direction A.

[0090] The linkage assembly 5 includes a gear 51 , a first rack 52 and a second rack 53 .

[0091] A horizontally oriented gear 51 is rotatably connected to the fixing element 31 .

[0092] The first force transmission member 32 is fixed with a first rack 52 extending in the first direction A, and the second force transmission member 33 is fixed with a second rack 53 extending in the first direction A. The first rack 52 and the corresponding second rack 53 are meshed at upper and lower sides of the corresponding gear 51 .

[0093] During use, when the first force transmission member 32 bears the pulling force F1 in the first direction A, the first force transmission member 32 drives the first rack 52 and the first core board 1 to move synchronously in the direction away from the second force transmission member 33, so that the first core board 1 is pulled. At the same time, the first rack 52 drives the gear 51 to rotate, and the gear 51 drives the second rack 53 fixed on the second force transmission member 33, the second force transmission member 33 and the second core board 2 to move synchronously in the direction away from the first force transmission member 32, so that the second core board 2 is compressed.

[0094] When the first force transmission member 32 bears the pressure F2 in the first direction A, the first force transmission member 32 drives the first rack 52 and the first core board 1 to move synchronously toward the direction close to the second force transmission member 33, so that the first core board 1 is compressed. At the same time, the first rack 52 drives the gear 51 to rotate, and the gear 51 drives the second rack 53 fixed on the second force transmission member 33, the second force transmission member 33 and the second core board 2 to move synchronously toward the direction close to the first force transmission member 32, so that the second core board 2 is pulled.

[0095] Therefore, the linkage assembly 5 can conveniently and accurately drive the two first force transmission members 32 and the second force transmission members 33 to move toward each other or away from each other simultaneously along the first direction A relative to the fixing member 31 .

[0096] Preferably, when the first force transmission member 32 and the second force transmission member 33 are both inserted into the first socket 311 and the second socket 312 in a movable manner along the first direction A:

[0097] Two groups of gear sets arranged up and down are provided on the fixing member 31 , each group includes at least one gear 51 . When a plurality of gears 51 are provided in each group, the plurality of gears 51 are arranged horizontally and spaced apart.

[0098] The first racks 52 are disposed on opposite sides of the two plug-in parts of the first force transmission member 32, and the second racks 53 are disposed on opposite sides of the two plug-in parts of the second force transmission member 33. The first racks 52 on the two plug-in parts of the two gear sets and the first force transmission plate and the second racks 53 on the two plug-in parts of the second force transmission member 33 correspond to each other, and the first racks 52 and the corresponding second racks 53 are meshed with the upper and lower sides of the corresponding gears 51, so as to improve the movement stability and accuracy of the first force transmission member 32 and the second force transmission member 33 when they are simultaneously approaching or moving away from each other along the first direction A relative to the fixing member 31.

[0099] Further, in order to facilitate the connection between the gear 51 and the fixing member 31 and the connection between the fixing constraint member 4 and the fixing member 31:

[0100] The fixing member 31 is fixed with a horizontally oriented connecting rod 6, and the gear 51 is sleeved on the connecting rod 6 and can rotate relative to the connecting rod 6. The end of the connecting rod 6 protrudes from the fixing member 31, and an external thread is provided at the end of the connecting rod 6. The fixing constraint member 4 is provided with a connecting hole for the end of the connecting rod 6 to extend out, and the end of the connecting rod 6 extending out of the fixing constraint member 4 is threadedly connected with a nut 7 that can abut against the fixing constraint member 4.

[0101] Thus, the gear 51 and the fixed constraint member 4 are both connected to the fixed member 31 through the connecting rod 6 to simplify the connection structure and facilitate assembly.

[0102] Optionally, the connecting rod 6 is welded to the fixing member 31 .

[0103] Furthermore, in order to adjust the load-bearing peak values ​​of the first core plate 1 and the second core plate 2, the load-bearing adjustable support of the modular steel structure also has the following settings:

[0104] The longitudinal section of the fixed constraint 4 is C-shaped. The fixed constraint 4 extends along the first direction A. The fixed constraint 4 can be sleeved on both horizontal sides of the first core board 1 and the second core board 2 and the open end of the fixed constraint 4 is fixedly connected to the fixing member 31.

[0105] The two sleeve parts of the fixed restraint member 4 are connected to relative pressing components 8. The two pressing components 8 are arranged opposite to each other and the ends are pressed on the horizontal sides of the first core board 1 and the second core board 2 to clamp the first core board 1 and the second core board 2 and constrain the deformation capacity of the two, so that the first core board 1 and the second core board 2 have the required bearing capacity.

[0106] The pressing assembly 8 includes two groups of pressing members 81 arranged at intervals along the first direction A, and the distance between the two groups of pressing members 81 is adjustable.

[0107] During processing, the effective length L of the first core board 1 and the second core board 2 participating in the load-bearing along the first direction A can be changed by adjusting the spacing between the two groups of top pressing members 81 along the first direction A and changing the spacing between the two groups of top pressing members 81 pressing on the first core board 1 and the second core board 2. Referring to the following formula, the effective length L is inversely proportional to the peak load-bearing value F of the core board. Therefore, by adjusting the spacing between the two groups of top pressing members 81, the peak load-bearing value of the first core board 1 and the second core board 2 along the first direction A that meets the needs can be conveniently adjusted and obtained at the same time, thereby realizing the auxiliary support function of the modular steel structure load-bearing adjustable support for the building structure in the normal use state of non-earthquake before and after the support load-bearing degradation.

[0108]

[0109] Wherein, E refers to the elastic modulus. I refers to the moment of inertia of the core plate in the direction of thickness D. L refers to the spacing between the two sets of top pressing members 81. α refers to the effective length coefficient when the two sets of top pressing members 81 are constrained.

[0110] It should be noted that the traditional way to adjust the peak load of the core panel is to change the material, shape or size of the core panel itself to change the stiffness of the core panel, and then change the peak load that is positively correlated with the stiffness. Therefore, when it is necessary to increase the peak load of the core panel, it is also necessary to increase the stiffness of the core panel accordingly, and the increase in the stiffness of the core panel will limit its tensile deformation capacity, and also limit its yield capacity. However, when the load-bearing peak of the core panel is adjusted, the load-bearing adjustable support of the modular steel structure does not change the own properties of the core panel, and will not change the stiffness, and realizes independent regulation of the load-bearing peak. Therefore, the load-bearing adjustable support of the modular steel structure can change the peak load of the first core panel 1 and the second core panel 2 separately without changing the stiffness of the two, and can ensure the stiffness of the core panel, effectively realize the fullness of the hysteresis curve, and ensure the auxiliary support of the core panel to the building structure in the normal use state of non-earthquake before and after the degradation of the tensile and compressive bearing capacity.

[0111] Specifically, each group of pressing parts 81 includes a row of constraint pins 811 screwed on the corresponding socket parts, the axial direction of the constraint pins 811 is horizontal, and a row of constraint pins 811 corresponds to the first core board 1 and the second core board 2. The ends of the constraint pins 811 can be pressed on the horizontal side of the corresponding first core board 1 or the second core board 2 to stably clamp the first core board 1 and the second core board 2.

[0112] Preferably, the material of the restraining pin 811 is steel to ensure the pressing ability.

[0113] Specifically, the connection method between the fixing restraint member 4 having a C-shaped longitudinal section and the fixing member 31 is as follows:

[0114] Both ends of the connecting rod 6 protrude from both sides of the fixing member 31, and both ends of the connecting rod 6 are provided with external threads. The open end of the fixing constraint member 4 is sleeved on both sides of the fixing member 31, and both sides of the open end of the fixing constraint member 4 are provided with connection holes for the ends of the connecting rod 6 to extend out, and both ends of the connecting rod 6 extending out of the fixing constraint member 4 are threadedly connected with nuts 7 that can abut against the fixing constraint member 4, so as to stably fix the fixing constraint member 4 on the fixing member 31.
