Abstract
Description
Technical Field
[0001] This invention relates to the field of glued laminated timber shear wall technology, and more particularly to an orthogonal glued laminated timber shear wall structure. Background Technology
[0002] Cross-laminated timber (CLT), as a modern engineered wood product, is widely used in mid- to high-rise timber-frame buildings due to its high strength, high stiffness, excellent dimensional stability, and green sustainability. Shear walls made of CLT are key lateral force resisting components in these structural systems to resist horizontal loads (such as wind loads and seismic forces).
[0003] However, the seismic performance of traditional CLT shear wall structures, especially their energy dissipation capacity, is largely limited by the performance of the connection nodes between walls and between walls and foundations. Currently, the common connection method mainly uses rigid connections formed by a large number of self-tapping screws, bolts, or other fasteners. These connections are designed to give the structure high initial stiffness, but under strong earthquakes, seismic energy cannot be effectively dissipated, which can easily lead to brittle failure of the cross-laminated timber itself, resulting in insufficient seismic toughness of cross-laminated timber shear wall structures. Summary of the Invention
[0004] The purpose of this invention is to provide an orthogonal glulam shear wall structure that can effectively dissipate seismic energy under strong earthquakes, avoid brittle failure of the orthogonal glulam boards themselves, and improve the seismic toughness of the orthogonal glulam shear wall structure.

[0012] This invention discloses an orthogonal glulam shear wall structure. During shear wall construction, two orthogonal glulam boards are first installed on a foundation or floor slab using an installation component, forming a vertical seam between them. Then, an energy-dissipating connecting component is bolted to the mounting holes of the two orthogonal glulam boards, allowing the energy-dissipating connecting component to span the vertical seam between the two orthogonal glulam boards, thus forming the orthogonal glulam shear wall structure.

Detailed Implementation
[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] The first embodiment of this application is as follows: Please see Figures 1-2 ,in, Figure 1 This is a schematic diagram of the overall structure of the first embodiment of the present invention; Figure 2 This is a structural schematic diagram of the energy-consuming connection component according to the first embodiment of the present invention.
[0021] This invention provides an orthogonal glulam shear wall structure, comprising orthogonal glulam boards 101 and shear wall components. The shear wall components include mounting members 102 and energy-dissipating connection members 103. The energy-dissipating connection members 103 include multiple cross-energy-dissipating elements 105 and two energy-dissipating buffer elements 106. The mounting members 102 include mounting steel plates 107 and reinforcing steel plates 108. The energy-dissipating buffer elements 106 include a connecting plate 109, two arc-shaped energy-dissipating plates 110, a mounting plate 111, a buffer spring 112, and a viscous damper 113. Through the aforementioned scheme, seismic energy can be effectively dissipated under strong earthquakes, avoiding brittle failure of the orthogonal glulam boards 101 themselves and improving the seismic toughness of the orthogonal glulam shear wall structure.
[0022] In this specific embodiment, the orthogonal plywood board 101 has a plurality of mounting screw holes 104, which are evenly distributed on both sides of the orthogonal plywood board 101; the mounting member 102 is disposed on the side of the orthogonal plywood board 101; the energy-dissipating connection member 103 includes a plurality of cross energy-dissipating components 105 and two energy-dissipating buffer components 106; the plurality of cross energy-dissipating components 105 are fixedly connected in sequence, and the two energy-dissipating buffer components 106 are disposed on both sides of the plurality of cross energy-dissipating components 105. When constructing a shear wall, two orthogonal plywood boards 101 are first installed on the mounting foundation or floor slab using the mounting member 102, forming a vertical seam between the two orthogonal plywood boards 101. Then, the energy-dissipating connecting member 103 is bolted to the mounting screw holes 104 of the two orthogonal plywood boards 101, allowing the energy-dissipating connecting member 103 to span the vertical seam between the two orthogonal plywood boards 101, thus forming an orthogonal plywood shear wall structure. The cross energy-dissipating component 105 is X-shaped and made of low-yield-point soft steel. During a strong earthquake, the shear wall experiences significant vibration. The plastic deformation of multiple cross energy-dissipating components 105 dissipates seismic energy, effectively dissipating seismic energy under strong earthquakes, preventing brittle failure of the orthogonal plywood boards 101 themselves, and improving the seismic toughness of the orthogonal plywood shear wall structure.
[0023] The mounting steel plate 107 and the orthogonal plywood board 101 are connected by bolts and are located at the bottom of the orthogonal plywood board 101. The reinforcing steel plate 108 is fixedly connected to the mounting steel plate 107 and is located on the side of the mounting steel plate 107. The mounting steel plate 107 is L-shaped, and both the mounting steel plate 107 and the orthogonal plywood board 101 have corresponding screw holes. The mounting steel plate 107 is connected to the orthogonal plywood board 101 by bolts, and the mounting steel plate 107 is fixed to the mounting base surface or floor slab by bolts. The reinforcing steel plate 108 is used to improve the stability of the mounting steel plate 107 and the orthogonal plywood board 101 after installation.
[0024] Secondly, the connecting plate 109 is fixedly connected to the plurality of cross energy dissipation components 105 and is located on the side of the plurality of cross energy dissipation components 105; the two arc-shaped energy dissipation plates 110 are respectively fixedly connected to the connecting plate 109 and are respectively located on one side of the connecting plate 109; the mounting plate 111 is fixedly connected to the two arc-shaped energy dissipation plates 110, and the mounting plate 111 is connected to the orthogonal plywood board 101 by bolts. The connecting plate 109 is provided with screw holes adapted to the mounting screw holes 104, and the connecting plate 109 can be installed on the orthogonal plywood board 101 by bolts. The two arc-shaped energy dissipation plates 110 are symmetrically arranged, and the material is low yield point mild steel. During a major earthquake, the plastic deformation of the arc-shaped energy dissipation plates 110 dissipates seismic energy.
[0025] Meanwhile, the buffer spring 112 is fixedly connected to the connecting plate 109 and the mounting plate 111, and is located between the connecting plate 109 and the mounting plate 111. When the wall panel vibrates, the buffer spring 112 can provide a buffering effect and provide the force required for reset after the vibration ends, so that the shear wall structure returns to its original position, thereby protecting the wall from deformation and damage.
[0026] Furthermore, the viscous damper 113 is fixedly connected to the connecting plate 109 and the mounting plate 111, and is located between the connecting plate 109 and the mounting plate 111. When the orthotropic plywood board 101 vibrates, the viscous damper 113 can dissipate the vibration energy.
[0027] When constructing a shear wall using this invention, firstly, two orthogonal plywood boards 101 are installed on the mounting foundation or floor slab using the mounting steel plate 107 and bolts, forming a vertical seam between the two orthogonal plywood boards 101. Then, the mounting plates 111 at both ends of the energy-dissipating connecting member 103 are bolted onto the mounting screw holes 104 of the two orthogonal plywood boards 101, so that the energy-dissipating connecting member 103 spans the vertical seam between the two orthogonal plywood boards 101, thereby forming an orthogonal plywood shear wall structure; the cross energy-dissipating component 10... The structure is X-shaped and made of low-yield-point soft steel. Two arc-shaped energy-dissipating plates 110 are symmetrically arranged and made of low-yield-point soft steel. During a strong earthquake, the shear wall experiences significant vibration. At this time, the seismic energy is dissipated through the plastic deformation of multiple cross-braced energy-dissipating components 105 and arc-shaped energy-dissipating plates 110. Simultaneously, the buffer spring 112 and the viscous damper 113 further buffer and dissipate energy. This effectively dissipates seismic energy under strong earthquakes, preventing brittle failure of the orthogonal laminated timber 101 itself and improving the seismic toughness of the orthogonal laminated timber shear wall structure.
[0028] The second embodiment of this application is as follows: Based on the first embodiment, please refer to Figures 3-4 ,in, Figure 3 This is a schematic diagram of the overall structure of the second embodiment of the present invention; Figure 4 This is a schematic diagram of the structure of the adjustment component and guide block according to the second embodiment of the present invention.
[0029] The orthogonal glued laminated timber shear wall structure provided by the present invention further includes a docking guide component 201; the docking guide component 201 includes a guide rail 202, an adjusting component 203 and a guide block 204; the adjusting component 203 includes a fixing plate 205, an adjusting seat 206, a screw 207 and two nuts 208; In this specific embodiment, the docking guide component 201 is disposed on the side of the orthogonal plywood board 101. The docking guide component 201 enables the two orthogonal plywood boards 101 to be accurately docked.
[0030] The guide rail 202 and the orthotropic plywood board 101 are connected by bolts and are located on the side of the orthotropic plywood board 101; the adjusting member 203 is located on the side of the door panel; the guide block 204 is located on the side of the adjusting member 203. Both the guide rail 202 and the adjusting member 203 have screw holes adapted to the mounting screw holes 104. Both the guide rail 202 and the adjusting member 203 are connected to the orthotropic plywood board 101 by bolts. When splicing two orthotropic plywood boards 101, one orthotropic plywood board 101 is bolted to the guide rail 202, and the other orthotropic plywood board 101 is bolted to the adjusting member 203 and the guide block 204. First, the orthotropic plywood board 101 with the guide rail 202 installed is fixed to the mounting base surface by the mounting steel plate 107. Then, another orthogonal plywood board 101 is hoisted above the target area, so that the guide block 204 of the orthogonal plywood board 101 is inserted into the guide rail 202. Then, the orthogonal plywood board 101 is lowered, so that the two orthogonal plywood boards 101 can be installed in the required position, realizing the rapid alignment and installation of the two orthogonal plywood boards 101. After the two orthogonal plywood boards 101 are fixed by the mounting steel plate 107, the guide rail 202 and the adjusting component 203 are removed, and then the energy-dissipating connecting component 103 can be installed on the two orthogonal plywood boards 101.
[0031] Secondly, the fixing plate 205 and the orthotropic plywood board 101 are connected by bolts and are located on the side of the orthotropic plywood board 101; the adjusting seat 206 is fixedly connected to the fixing plate 205 and is located on the side of the fixing plate 205; the screw 207 and the guide block 204 are fixedly connected and pass through the adjusting seat 206; the two nuts 208 are respectively threaded to the screw 207 and are respectively located on the side of the screw 207. The fixing plate 205 has screw holes that match the mounting screw holes 104. The fixing plate 205 can be connected to the orthogonal plywood board 101 by bolts. The adjusting seat 206 has a through hole for the screw 207 to pass through. Since a vertical gap needs to be left between the two orthogonal plywood boards 101, the length of the guide block 204 can be adjusted by moving the position of the screw 207 on the adjusting seat 206. When the length of the guide block 204 is changed, the distance between the two orthogonal plywood boards 101 will also change when the guide block 204 slides into the guide rail 202. This allows control over the width of the vertical gap between the two orthogonal plywood boards 101, adapting to different installation conditions. Rotating the nut 208 to abut against the side of the adjusting seat 206 can fix the position of the screw 207.
[0032] Finally, the guide rail 202 has a T-slot 209 located inside the guide rail 202. The T-slot 209 can restrict the horizontal movement of the guide block 204, and the guide rail 202, in conjunction with the guide block 204, can provide guidance for the mating of the two orthogonal plywood boards 101.
[0033] When using this invention, when splicing two orthotropic plywood boards 101, one orthotropic plywood board 101 is bolted to the guide rail 202, and the other orthotropic plywood board 101 is bolted to the adjusting member 203 and the guide block 204. First, the orthotropic plywood board 101 with the guide rail 202 is fixed to the mounting base surface by the mounting steel plate 107. Then, the other orthotropic plywood board 101 is hoisted above the target area, so that the orthotropic plywood board 101... The guide block 204 is inserted into the T-slot 209 of the guide rail 202, and then the orthogonal plywood board 101 is lowered, so that the two orthogonal plywood boards 101 can be installed in the required position, realizing the quick alignment and installation of the two orthogonal plywood boards 101; after the two orthogonal plywood boards 101 are fixed by the mounting steel plate 107, the guide rail 202 and the adjusting member 203 are removed, and then the energy-dissipating connecting member 103 can be installed on the two orthogonal plywood boards 101.
[0034] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
