Description

Technical Field

[0001] This invention relates to the field of buckling damping technology, specifically a buckling restraint support device. Background Technology

[0002] Buckling-restrained braces (BRBs) are dual-function structural members installed in building structures, serving both load-bearing and energy-dissipating purposes during earthquakes. They consist of a core material, a sleeve to restrain buckling of the core material, and unbonded material and filler (if applicable) between the core material and the sleeve. BRBs avoid the significant difference in tensile and compressive load-bearing capacity inherent in conventional braces, while also possessing the energy dissipation capabilities of metal dampers, acting as a "fuse" within the structure to keep the main structure within its elastic range. Therefore, the application of BRBs can comprehensively improve the seismic performance of traditional braced frames. Since BRBs are connected to other components only by the core plate, all loads are borne by the core plate. The sleeve and filler only restrain the core plate from compressive buckling, allowing the core plate to yield under both tension and compression. Consequently, BRBs exhibit excellent hysteretic performance.

[0003] However, buckling restraint braces are often difficult to install in one go due to their large size. The current approach is to pre-fix them by welding and then gradually adjust the installation position. If the installation deviation is large, the weld points need to be broken open, which makes it difficult to limit the overall position of the brace structure. Moreover, the overall installation is time-consuming.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a buckling restraint support device that enables rapid positioning and installation of large buckling restraint support devices.

[0006] The technical solution adopted by this invention to solve its technical problem is: A buckling restraint support device includes an energy-dissipating core material and embedded blocks. The embedded blocks are placed at both ends of the energy-dissipating core material. A connecting block that connects to the energy-dissipating core material is provided on the side of the embedded block near the energy-dissipating core material. Guide components are also provided at both ends of the energy-dissipating core material. The guide components include a first splicing block, a second splicing block, a connecting rod, and a C-shaped fixing ring. After the first splicing block and the second splicing block are spliced ​​together, the gap in the middle is engaged with the energy-dissipating core material.

[0007] Compared with the prior art, the beneficial effects of the present invention are: By setting up a guide component, the energy-consuming core material can be guided when it is installed onto the surface of the embedded block, thus preventing the energy-consuming core material from tilting during installation. The overall operation is quick and labor-saving.

[0008] As a preferred embodiment, a further technical solution of the present invention is: Preferably, the first splicing block is provided with connecting rods on the front and back, and the second splicing block is provided with C-shaped fixing rings on the front and back that engage with the connecting rods. The C-shaped fixing rings are connected to their corresponding connecting rods by fasteners.

[0009] Preferably, it also includes a fixing component, which includes a guide groove and a guide block. Each connecting rod has a guide groove on its outer side, and a guide block is movably disposed inside each guide groove. Each guide block is connected to its corresponding guide groove by an elastic element. A limit rod is provided on the outer side of the guide block. The limit rod is movably disposed with the connecting rod. A limit box is provided on the pre-embedded block corresponding to the position of each connecting rod. Each limit box has a limit hole that engages with the limit rod on its respective side.

[0010] Preferably, the top wall of the guide groove is provided with a slot, and a push rod is provided at the upper end of the guide block. The end of the push rod passes through the slot and extends to the outside of the slot.

[0011] Preferably, the width of the push rod is smaller than the width of the side opening of the C-shaped retaining ring.

[0012] By setting up a fixing component, the guide component and the fixing component as a whole can have the advantage of quick assembly and disassembly. Attached Figure Description

[0014] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0015] like Figures 1 to 5 As shown, a buckling restraint support device is composed of an energy-dissipating core material 5, a pre-embedded block 3, a guide component 1, and a fixing component 2. The energy-dissipating core material 5 is wrapped with a sleeve 6, and mortar is filled between the sleeve 6 and the energy-dissipating core material 5.

[0016] Each end of the energy-consuming core material 5 is provided with a pre-embedded block 3, and each pre-embedded block 3 is fixedly connected with a connecting block 4 that is connected to the energy-consuming core material 5. The connecting block 4 is used to fix the energy-consuming core material 5 to the surface of the pre-embedded block 3.

[0017] The energy-consuming core material 5 is also provided with guide components 1 at both ends. The guide components 1 are composed of a first splicing block 101, a second splicing block 102, a connecting rod 103, and a C-shaped fixing ring 104. The first splicing block 101 is provided with a connecting rod 103 on its front and back sides respectively. The second splicing block 102 is provided with a C-shaped fixing ring 104 on its front and back sides respectively, which is engaged with the connecting rod 103. The C-shaped fixing ring 104 and its corresponding connecting rod 103 are connected by fasteners 105 (screws in this embodiment). After the first splicing block 101 and the second splicing block 102 are spliced ​​together, the gap in the middle is engaged with the energy-consuming core material 5.

[0018] The fixing component 2 consists of a guide groove 201 and a guide block 202. A guide groove 201 is opened on the outer side of each connecting rod 103. A guide block 202 is movably connected inside each guide groove 201. Each guide block 202 is connected to the inner wall of the guide groove 201 it is in through an elastic element 203. In this embodiment, the elastic element 203 is a spring.

[0019] Each guide block 202 is fixedly connected to a limiting rod 204 on its outer side. The connecting rod 103 is provided with a limiting groove 205 at the position corresponding to the limiting rod 204. The limiting rod 204 and the limiting groove 205 are slidably arranged.

[0020] Limiting boxes 7 are fixedly connected to the pre-embedded block 3 at the positions corresponding to each connecting rod 103. Each limiting box 7 has a limiting hole 8 that engages with the limiting rod 204 on its respective side.

[0021] In this embodiment, the limiting rod 204 is provided with a smooth outer surface, which allows the limiting rod 204 to enter the interior of the guide groove 201 more smoothly.

[0022] The top wall of the guide groove 201 has a hollow groove 206. A push rod 207 is fixedly connected to the upper end of the guide block 202. The end of the push rod 207 passes through the hollow groove 206 and extends to the outside of the hollow groove 206. Pushing the push rod 207 can release the locking of the limiting rod 204 to the connecting rod 103 through the limiting hole 8.

[0023] The width of the push rod 207 is smaller than the width of the side opening of the C-shaped fixing ring 104, so as to facilitate the separation of the first splicing block 101 and the second splicing block 102.

[0024] When it is necessary to install the energy-consuming core material 5 and the sleeve 6 as a whole, first insert a set of connecting rods 103 as a whole from above the C-shaped fixing ring 104. Then, when the first splicing block 101 and the second splicing block 102 are in a horizontal state, use screws to fix the overall position of the connecting rods 103 and the C-shaped ring, so as to achieve the purpose of splicing the first splicing block 101 and the second splicing block 102. Insert the two connecting rods 103 at this end of the energy-consuming core material 5 as a whole into the limiting box 7. At this time, the inclined surface of the limiting rod 204 will be squeezed into the guide groove 201 by the top surface of the limiting box 7. Then, when the connecting rod 103 is inserted into the state where the limiting rod 204 and the limiting hole 8 are in a relative position, the guide block 202 can be inserted into the limiting hole 8 under the action of the spring force, thereby achieving the purpose of fixing the first splicing block 101 and the second splicing block 102. The energy-consuming core material 5 and the bundle sleeve 6 are hoisted together, so that one end of the energy-consuming core material 5 passes through the gap between the first splicing block 101 and the second splicing block 102. At this time, under the guiding action of the gap between the first splicing block 101 and the second splicing block 102, the energy-consuming core material 5 can pass through the first splicing block 101 and the second splicing block 102 and smoothly reach the surface of the connecting block 44. At this time, the welding work of the energy-consuming core material 518 can be carried out.

[0025] In this embodiment, since the energy-consuming core material 5 is too long overall, in the hoisting state, the other end of the energy-consuming core material 5 may be aligned with the connecting block 4 at its end. At this time, the first splicing block 101 and the second splicing block 102 can be assembled on the surface of the energy-consuming core material 5 at this end first, and then connected to the limiting box 7.

[0026] When disassembling after welding, simply press the push rod 207 into the interior of the empty slot 206. Through the connection between the push rod 207 and the guide block 202, the limit rod 204 can be pushed into the interior of the guide slot 201 to release the locking of the connecting rod 103. Then, unscrew the screws and pull the connecting rod 103 out of the interior of the limit box 7 and out of the interior of the C-shaped retaining ring 104.

[0027] By setting a guide component, this invention can provide guidance when installing the energy-consuming core material onto the surface of the pre-embedded block, thus avoiding the installation of the energy-consuming core material at an angle. The overall operation is quick and labor-saving. By setting a fixing component, the guide component and the fixing component can be quickly assembled and disassembled. In the initial production, it is only necessary to fix the connecting block to the surface of the pre-embedded block 3, making the whole device reusable.
