Description

Technical Field

[0001] This invention relates to the field of building wall technology, and in particular to a wall component that combines wind and earthquake resistance and its assembly method. Background Technology

[0002] Existing prefabricated building exterior walls rely solely on the rigidity of the frame structure to withstand wind loads and seismic forces, lacking independent buffer and energy dissipation structures. Conventional wall damping structures can only adapt to forces in a single direction, exhibiting significant limitations.

[0003] When only damping components are installed, the wall cannot be effectively buffered when it vibrates out of the plane of the steel frame in strong winds. The wall panels and the frame are prone to rigid collisions, causing the wall to crack and fall off. When only damping structures are installed, the seismic compression load cannot be dissipated, and the seismic impact can easily damage the wall panel connection nodes.

[0004] Square and block-shaped shock absorbers can only bear pressure on one side, resulting in dead angles in the stress distribution and making them unable to adapt to slight deviations in any direction of the wall. Traditional shock absorber structures are difficult to disassemble and assemble, and subsequent maintenance and replacement of damping components are cumbersome.

[0005] Therefore, there is an urgent need for a prefabricated wall component that can simultaneously adapt to seismic compression and wind load displacement, and can withstand pressure and dissipate energy in all directions. Summary of the Invention

[0006] To address the technical problems existing in the background art, the present invention proposes a wall component that combines wind resistance and earthquake resistance, and its assembly method.

[0007] The present invention proposes a wall component that combines wind resistance and earthquake resistance, comprising a steel frame, precast wall panels, and damping cross braces. The damping cross braces are arranged diagonally at opposite corners of the steel frame, with both ends of the damping cross braces hinged to the four corners of the steel frame, and the middle of the damping cross braces flexibly connected to the back of the precast wall panels; it also includes several cylindrical energy-absorbing components and a base.

[0008] Each cylindrical energy-absorbing component is clamped between the base of the steel frame and the precast wall panel; the base is fixed inside the steel frame, and support members are provided on both sides of the base, with sliding grooves provided in the support members;

[0009] The cylindrical energy-absorbing component includes a main shaft with both ends slidably mounted in sliding grooves; the base is provided with an inner concave arc surface adapted to the outer wall of the cylindrical energy-absorbing component, and a snap-fit ​​groove is provided on the contact side of the prefabricated wall panel and the cylindrical energy-absorbing component, with one side of the cylindrical energy-absorbing component fitting the inner concave arc surface and the other side snapped into the snap-fit ​​groove.

[0010] Preferably, the cylindrical energy-absorbing assembly further includes multiple arc-shaped plates and multiple sets of energy-absorbing mechanisms; the multiple arc-shaped plates are evenly spaced along the circumference of the main axis, with a deformation gap reserved between adjacent arc-shaped plates, and all the arc-shaped plates together form the outer wall of the cylinder; each arc-shaped plate is provided with a set of energy-absorbing mechanisms corresponding to the main axis, and a single arc-shaped plate can independently radially contract and deform when it is under pressure, relying on the corresponding energy-absorbing mechanism.

[0011] Preferably, a single set of the energy-absorbing mechanism consists of two sets of X-shaped telescopic structures arranged symmetrically.

[0012] Each X-type telescopic structure includes a first fixing component, a first sliding component, a second fixing component, a second sliding component, a first connecting rod, and a second connecting rod;

[0013] The inner side of the arc-shaped plate is provided with a first fixing member and a first sliding member, and the outer wall of the main shaft is provided with a second fixing member and a second sliding member accordingly;

[0014] A first connecting rod is hinged between the first fixed member and the second sliding member, and a second connecting rod is hinged between the first sliding member and the second fixed member. The first connecting rod and the second connecting rod are hinged together at the middle to form a single X-shaped telescopic structure.

[0015] Two sets of X-shaped telescopic structures are arranged symmetrically, with the first and second fixing parts located on the outer side and the first and second sliding parts located on the inner side; buffer springs are respectively installed between the first sliding parts of the two sets of X-shaped telescopic structures and between the second sliding parts of the two sets of X-shaped telescopic structures.

[0016] When the arc-shaped plate is squeezed towards the main shaft by external force, the two sets of X-shaped telescopic structures rotate synchronously to compress the buffer spring, and dissipate the vibration energy by means of spring deformation; after the external force disappears, the buffer spring rebounds and drives the arc-shaped plate to reset.

[0017] Preferably, at least two sets of energy-absorbing mechanisms are arranged axially between the single arc-shaped plate and the main shaft.

[0018] Preferably, the damping cross brace is a rigid rod with adjustable preload, and the middle part of the damping cross brace is flexibly locked to the center of the back of the precast wall panel by bolts with buffer pads.

[0019] Preferably, the support member is arranged vertically, and the sliding groove extends in a direction perpendicular to the concave arc surface of the base, with the sliding groove reserved for the displacement stroke of the main shaft.

[0020] Preferably, the base is installed on the top, bottom, left and right sides of the steel frame and the precast wall panel, respectively, and several cylindrical energy-absorbing components are evenly distributed on each side.

[0021] An assembly method for a wall component that combines wind and earthquake resistance includes the following steps:

[0022] S1. Hinge the two ends of the damping cross brace to the four corners of the steel frame, and lock it after adjusting the preload of the damping cross brace.

[0023] S2. Hoist the precast wall panel into the steel frame and use temporary supports to temporarily limit the position of the precast wall panel so that the center of the back of the precast wall panel is aligned with the midpoint of the cross brace of the damping cross brace.

[0024] S3. The middle part of the damping cross brace is flexibly locked to the center of the back of the precast wall panel using bolts with buffer pads.

[0025] S4. Fix the base on the top, bottom, left and right sides of the inner side of the steel frame respectively. Place the cylindrical energy absorption component on the concave arc surface of the base, so that the two ends of the main shaft of the cylindrical energy absorption component slide into the sliding groove of the support on both sides of the base, and insert the outer side of the cylindrical energy absorption component into the corresponding snap-fit ​​groove of the precast wall panel.

[0026] S5. Remove temporary supports, fine-tighten the damping cross braces, calibrate the centering of the precast wall panels, and complete the overall assembly.

[0027] The wall component and its assembly method proposed in this invention, which combine wind and earthquake resistance, have the following beneficial effects:

[0028] Taking into account both wind and earthquake resistance, the wall panel achieves seismic energy absorption when it vibrates within the plane of the steel frame during an earthquake; the cylindrical energy absorption component contacts the concave arc surface of the base and the snap-fit ​​groove on the side wall of the precast wall panel, and the radial contraction of the arc panel dissipates the impact force.

[0029] When wind load causes the wall panel to vibrate outside the plane of the steel frame, the side wall of the wall panel's locking groove presses against the outer wall of the cylinder, and the side wall of the groove presses against the outer wall of the cylinder to complete the lateral wind resistance and energy dissipation.

[0030] The split-type arc-shaped plate independent damping system consists of multiple independent arc-shaped plates surrounding the outer wall of the cylinder. Local stress corresponds only to the deformation of a single arc-shaped plate, resulting in a more sensitive damping response. Any contact surface can deform and absorb energy, eliminating stress dead angles.

[0031] Symmetrical X-type linkage spring buffer mechanism: Each energy absorption mechanism is equipped with two sets of axisymmetric X-type telescopic structures, combined with bidirectional buffer springs, which have stable deformation, strong reset ability, and can repeatedly absorb vibration energy, resulting in better durability; the structure is easy to disassemble and maintain, the cylindrical energy absorption components are only slidably assembled into the sliding groove through the main shaft, and can be disassembled and replaced individually in the future; the damping diagonal brace preload is adjustable to adapt to the wind pressure and seismic resistance requirements of different regions.

[0032] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0043] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] like Figures 1-5 The wall component shown is designed to be both wind-resistant and earthquake-resistant. The main body consists of a steel frame 1, precast wall panels 2, damping cross braces 101, a base 4, and cylindrical energy-absorbing components 3.

[0045] The steel frame 1 has four corners hinged damping cross braces 101. The midpoint of the cross braces is flexibly connected to the back of the precast wall panel 2 through bolts with buffer pads. The preload can be adjusted to limit the center of the wall panel and help dissipate oblique vibration.

[0046] The steel frame 1 has four fixed bases 4 on its inner sides (top, bottom, left, and right). Support members 401 are vertically installed on both sides of the bases 4, each with a vertical sliding groove designed for vertical sliding travel. A cylindrical energy-absorbing component 3 is clamped between the concave arc surface of the base 4 and the engaging groove 201 of the precast wall panel 2. The two ends of the component's central main shaft 301 slide into the sliding groove. During an earthquake, the wall panel vibrates within the plane of the steel frame 1, compressing the arc-shaped plate 302 to absorb energy.

[0047] The cylindrical energy-absorbing component 3 includes a main shaft 301 and eight arc-shaped plates 302. The eight arc-shaped plates 302 are evenly arranged around the main shaft 301. Adjacent arc-shaped plates 302 have reserved deformation gaps and together form a complete cylindrical outer surface. The outer arc surface of the arc-shaped plates 302 is perfectly matched with the concave arc surface of the base 4 and the inner arc of the groove of the wall panel. When the steel frame vibrates outside the plane, the wall panel clamps the groove side wall and squeezes the outer wall of the cylinder. The groove side wall presses against the outer wall of the cylinder to complete the lateral wind resistance and energy dissipation.

[0048] Two sets of energy-absorbing mechanisms 303 are evenly arranged axially between the single arc-shaped plate 302 and the main shaft 301. Each set of energy-absorbing mechanisms 303 includes two sets of axisymmetric X-shaped telescopic units. A first fixing member 3031 is provided on the outer side of the inner side of the arc-shaped plate 302, and a first sliding member 3032 is provided on the inner side. A second fixing member 3033 is provided on the outer side of the outer wall of the main shaft 301, and a second sliding member 3034 is provided on the inner side. The first fixing member 3031 is hinged to the first connecting rod 3035 to the second sliding member 3034, and the first sliding member 3032 is hinged to the second connecting rod 3036 to the second fixing member 3033. The two connecting rods are hinged together at the middle with a pin to form a single X-shaped structure. The two X-structures are arranged symmetrically from left to right, and buffer springs 3037 are respectively installed between the two sets of first sliding members 3032 and between the two sets of second sliding members 3034.

[0049] When any side of the arc plate 302 is compressed, the two sets of X-shaped telescopic structures open and close synchronously, compressing the buffer spring 3037 and consuming vibration energy by relying on the elastic deformation of the spring; after the external force disappears, the spring rebounds, causing the arc plate 302 to return to its original cylindrical shape, which can be used for repeated shock absorption.

[0050] In this embodiment, during operation:

[0051] A method for assembling wall components, comprising the following steps:

[0052] S1. Hinge the two ends of the damping cross brace 101 to the four corners of the frame, rotate the threaded section of the brace to adjust the preload, and then tighten the nut.

[0053] S2. Use lifting equipment to hoist the precast wall panel 2 into the cavity of the steel frame 1, and use wooden blocks to temporarily support both sides of the wall panel so that the center of the back of the wall panel is aligned with the intersection of the damping diagonal braces.

[0054] S3. Install a rubber buffer pad between the midpoint of the diagonal brace and the wall panel, and use bolts to achieve flexible locking;

[0055] S4. Weld and fix the base 4 on the four sides of the inner side of the steel frame 1 respectively. Place the cylindrical energy absorption component 3 on the concave arc surface of the base 4. Slide the two ends of the main shaft 301 into the sliding groove of the support 401 and push the wall panel inward so that the outer side of the cylindrical energy absorption component is locked into the locking groove 201 on the side of the wall panel.

[0056] S5. Remove the temporary supporting timber, fine-tighten the damping brace preload, correct the wall panel to center, and complete the assembly of the entire wall system.
