Description

Technical Field

[0001] The invention relates to the technical field of building supports, in particular to a rhombus-arranged buckling restrained support for buildings. Background Art

[0002] Buckling support is a support measure used to prevent structural rods or components from buckling when subjected to external forces. Publication number: CN216689748U announces a buckling restrained support structure arrangement system for buildings, including frame columns, frame beams, buckling restrained supports and connecting node elements. A rectangle is formed between the frame columns and the frame beams. There are four buckling restrained supports, and the two ends of each buckling restrained support are respectively fixed to the middle of the frame column and the frame beam through connecting node elements. The four buckling restrained supports form a diamond-shaped building window opening.

[0003] However, the following technical limitations still exist: During the actual installation, it is necessary to pre-install the fixing seats on the upper and lower beams and the two side columns of the building components, and then move them to the installation position by hoisting, and manually weld the two ends of the buckling support to connect the beams and columns. This installation method needs to be repeated four times to complete the installation of the diamond-arranged buckling support. The overall operation process is complicated and basically relies on welding connection. Although welding has good stability, it cannot guarantee that the overall diamond buckling support can be arranged quickly. When facing the position where auxiliary reinforcement support is required at zero time, such as the local damage of the building after the earthquake requires emergency reinforcement, the sudden load during the construction process causes the structure to become unstable, and the unforeseen stress concentration occurs during the renovation of the existing building. In such engineering rescue or dynamic adjustment conditions that require rapid response, the traditional welding installation method cannot meet the real-time reinforcement needs. Moreover, in a wet working environment (such as a construction site in the rainy season), the welding process parameters are difficult to accurately control, and quality defects such as cold welding and cracks are more likely to occur, further exacerbating the structural safety risk.

The chemical expansion bolt 112 is a prior art structure. A hole is punched in the building component in advance and then the chemical expansion bolt 112 is inserted. Then the base plate 111 passes through the chemical expansion bolt 112 to contact the building component. Finally, a nut is screwed into the chemical expansion bolt 112 to complete the connection between the base plate 111 and the building component. The top of the base plate 111 is fixedly connected to a middle plate frame 113, and side protrusions 114 are fixedly connected to both sides of the middle plate frame 113.

The hexagonal head 123 is a hexagonal nut structure. When the overall flexure support needs to be unfolded through the drive assembly 12, the hexagonal head 123 can be driven to rotate by an external heavy-duty impact screwdriver in conjunction with a hexagonal socket to unfold the overall flexure support. The inner shaft 124 in the drive assembly 12 and the spline shaft 131 in the transmission adjustment assembly 13 are connected through an umbrella gear assembly. The umbrella gear assembly includes two umbrella teeth, which are meshed and connected. One umbrella tooth is connected to the inner shaft 124 through a through hole, and the other umbrella tooth is fixedly connected to one end of the spline shaft 131.

[0022] refer to Figure 8 and Fig. 9The transmission adjustment component 13 includes a spline shaft 131, and a spline sleeve 132 is meshed on the spline shaft 131. The spline shaft 131 and the spline sleeve 132 are both structures in the prior art. The spline sleeve 132 can move axially on the spline shaft 131, and while moving axially, it will rotate with the rotation of the spline shaft 131.

[0024] refer to Fig. 9 As shown in , a portion of the spline shaft 131 extends into the inner housing 121, and the extending portion is a complete cylindrical surface without a toothed structure, and the cylindrical surface of the spline shaft 131 is connected to the inner housing 121 through a bearing.

[0025] refer to Figure 2 and Figure 3 As shown in the figure, the buckling support frame assembly 14 includes a buckling support rod 141, one end of which is fixedly connected to a mounting frame 142, and the mounting frame 142 is connected to an adjusting head 143 through a rotating shaft, and a mounting bolt 144 is arranged inside the adjusting head 143. The buckling support rod 141 is also a structure existing in the prior art, which includes a core rod and a shell sleeved thereout, and mortar is filled between the shell and the core rod. When the building components are deformed under an earthquake, the core rod in the buckling support rod 141 will first absorb the dynamic energy, so as to achieve the purpose of improving the stability of the overall building frame.

[0026] refer to Figure 1-Figure 3 As shown, the lateral mounting seat component set 200 includes a lateral seat body 201 and a chemical expansion bolt 202. There are two sets of lateral mounting seat component sets 200, and the two sets of lateral mounting seat component sets 200 are symmetrically arranged on the column of the building component.

[0027] The side seat body 201 is connected to the column through a chemical expansion bolt 202 , the side seat body 201 is in contact with the adjustment head 143 through a groove, and the side seat body 201 and the adjustment head 143 are connected through a mounting bolt 144 .

[0028] The energy absorbing component group 15 includes a friction sleeve 151 and a friction block 152 . The friction sleeve 151 is sleeved on the inner transmission shaft 125 . The friction block 152 is placed in the inner housing 121 . The friction block 152 and the friction sleeve 151 are in friction contact.

[0029] Working principle: The working principle of this integral buckling brace can be divided into three stages: installation preparation, mechanical deployment, and energy dissipation. The specific implementation process is as follows: 1. Pre-installation folded state like Fig.11 As shown, the buckling support component group 100 in the transport state remains in a folded state, and the two buckling support frame assemblies 14 are arranged in parallel. At this time, the overall structure is compact and convenient for transportation and lifting operations. The support seat assembly 11 is rotatably connected with the adjustment frame seat 136 through the side protrusion 114 of the middle plate frame 113, and the inner cylinder member 135 in the transmission adjustment assembly 13 is in the contracted state of the sleeve member 1341.

[0030] 2. Mechanical expansion process Drive system start The operator uses a heavy-duty impact driver with a hexagonal socket and the hexagonal head 123 of the drive assembly 12 ( Figure 8 , Fig. 9 The rotation of the hexagonal head 123 is transmitted to the inner transmission shaft 125 through the inner shaft 124, and after the bevel gear assembly is reversed, the spline shaft 131 is driven to rotate synchronously.

[0031] Transmission linkage The rotation of the spline shaft 131 is driven by the meshing transmission of the spline sleeve 132, and the second set of bevel gear components drives the threaded rod 134 to rotate. At this time, the inner moving shell 133 drives the sleeve member 1341 and the inner cylinder member 135 to form an axial telescopic movement under the constraint of the slide rail of the guide frame 137. As the inner cylinder member 135 extends from the sleeve member 1341, the adjustment frame seat 136 rotates axially around the side protrusion member 114, pushing the buckling support frame assembly 14 to complete the V-shaped expansion.

[0032] 3. Structural installation and energy dissipation Main body installation positioning After expansion ( Figure 2 , Figure 3 ), the overall position is adjusted by the hoisting hook of the guide frame 137. After the adjustment head 143 is aligned with the groove of the side seat body 201, the bolt 144 is installed to complete the lateral connection, and the base plate 111 is fixed to the building component by the chemical expansion bolt 112. At this time, the two groups of buckling support frame assemblies 14 form an angle of about 120°, forming a stable V-shaped support structure.

[0033] Energy absorption system After removing the cover plate 122, the friction block 152 of the energy absorbing component group 15 is stuffed into the cavity of the inner shell 121 to cover the friction sleeve 151. After reinstalling the cover plate 122, a closed friction system is formed. When the building component is deformed by the earthquake: the structural deformation is transmitted to the transmission system through the buckling support rod 141, the inner transmission shaft 125 drives the friction sleeve 151 to rotate, and the sliding friction between the friction block 152 and the friction sleeve 151 consumes the impact energy.

[0034] 4. Diamond support layout like Figure 1 As shown, two groups of inverted buckling support component groups 100 form a diamond arrangement in a square building component. Compared with the traditional diagonal bracing scheme, this layout has the following advantages: there is no structural shielding in the central area, ensuring the integrity of the internal space of the building; the two-way symmetrical structure can evenly distribute the seismic force; the force transmission path at the four corners is shortened, improving the torsional rigidity of the structure; the open central area is conducive to the layout of equipment pipelines and natural lighting.

[0035] This working principle realizes the three-stage functional integration of building support structure transportation, deployment and energy absorption through the synergistic effect of mechanical transmission and friction energy consumption, optimizing the utilization rate of building space while ensuring seismic performance.

[0036] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
