Description

Technical Field

[0001] The utility model relates to a connection technology of an assembled shear wall structure in the field of construction, in particular to a novel assembled composite reinforced consumable connector for a shear wall. Background Art

[0002] In order to reduce greenhouse gas emissions and promote the green transformation of economic and social development, the Chinese government has brought unprecedented development opportunities and challenges to the construction industry. As one of the important directions for green development in the construction industry, prefabricated structures are gaining more and more attention due to their fast construction speed, high quality, low resource consumption, and low environmental pollution. Among prefabricated structures, prefabricated shear wall structures occupy an important position due to their superior seismic performance and good spatial adaptability. Shear wall structures can effectively resist lateral forces and ensure the stability and safety of buildings in natural disasters such as earthquakes. The promotion and application of prefabricated shear wall structures will not only help achieve the energy conservation and emission reduction goals of the construction industry, but also improve the durability and service life of buildings, providing strong support for the realization of sustainable development.

[0003] Prefabricated structures, whose components are prefabricated in factories and then transported to on-site for assembly, offer advantages such as fast construction and controlled quality. However, these structures also present potential challenges and difficulties when facing natural disasters such as earthquakes. Prefabricated structures' components are connected through joints, and the seismic performance of these joints is crucial to the stability of the entire structure. Due to the independence of their components, prefabricated structures lack the integrity of traditional cast-in-place structures. Under earthquakes, prefabricated structures may exhibit nonlinear responses, requiring design considerations for their performance under extreme conditions. Once a prefabricated structure is damaged in an earthquake, repair work can be more complex and difficult than with cast-in-place structures due to the prefabricated nature of its components. Utility Model Content

[0004] The purpose of the present utility model is to provide a novel shear wall assembled composite reinforced consumable connector in order to solve the above problems.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] The utility model discloses a novel shear wall assembled composite reinforced consumable connecting piece, comprising a first fixing piece and a second fixing piece, wherein the first fixing piece comprises two L-shaped first connecting blocks facing opposite to each other, one side of the first connecting block is penetrated by a uniformly distributed first connecting hole, the vertical side of the first connecting block is provided with two rows of uniformly distributed second connecting holes, the bottoms of the two first connecting blocks on opposite sides are provided with a connecting plate, the surface of the connecting plate is provided with uniformly distributed third connecting holes, the second fixing piece comprises two second connecting blocks, the top of the second connecting block is provided with an additional block, the top of the additional block is penetrated by a fourth connecting hole with the same arrangement as the third connecting holes, a U-shaped block is connected to the middle part of one side of the second connecting block, and the U-shaped block semi-surrounds the second connecting block, and a uniformly distributed and removable U-shaped plug-in is provided between the U-shaped block and the second connecting block, two connecting frames are provided between the two second connecting blocks, and the two connecting frames and the two second connecting blocks jointly clamp the shear wall.

[0007] As an optimal technical solution for a new type of shear wall assembled composite reinforced consumable connector of the utility model, the third connecting hole matches the fourth connecting hole in size, and the third connecting hole and the fourth connecting hole are connected by bolts, so that the first fixing member and the second fixing member are fastened together.

[0008] As an optimal technical solution for a novel shear wall assembled composite reinforced consumable connector of the present invention, the first connection hole is connected to the shear wall by bolts, and the second connection hole is connected to the shear wall by bolts.

[0009] As an optimal technical solution for a novel shear wall assembled composite reinforced consumable connector of the present invention, the first fixing member and the second fixing member are both made of high-strength steel material.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. The utility model realizes effective absorption and dispersion of earthquake energy by concentrating the main energy dissipation on specific energy-dissipating connection nodes, thereby strengthening the shear wall structure. The energy-dissipating connection parts adopt replaceable plates. These plates mainly undertake the energy-dissipating task during earthquakes. Once damaged, they can be quickly replaced, thereby improving the maintainability and durability of the structure.

[0012] 2. Different from the traditional bolt connection method, the original ordinary bolt riveting was abandoned. The stress characteristics of retaining walls in engineering were used to specifically invent a connection device with better stress performance and load resistance. The sloped connecting steel plate can better withstand the pressure acting on the connecting parts. In addition, on top of this, the outer enveloping L-shaped steel plate link structure allows the structural stress to fully exert its performance. The replaceable plate design, the connection height design, and the energy-dissipating connection parts use replaceable plates. These plates mainly bear the energy-dissipating task in earthquakes. Once damaged, they can be quickly replaced, which improves the maintainability and durability of the structure. Bolt rod sliding friction energy dissipation: The bolt rod is designed to slide in the bolt hole, using the friction generated by sliding to consume earthquake energy, thereby improving the seismic performance of the structure.

[0013] 3. The connection structure provided by the present invention greatly improves the stability of the overall structure in terms of stress and reinforcement; the material of the steel plate mainly uses low-yield point steel plate as the material of the replaceable plate. This material has good plastic deformation ability and low-cycle fatigue performance, which effectively improves the seismic performance of the structure; the L-shaped steel plate wall corner design enhances the rigidity and strength of the connection area, while protecting the concrete from damage and avoiding the crushing damage to the wall caused by energy-consuming connectors. The overall structural design is relatively simple, which is convenient for construction personnel to operate and maintain later. At the same time, the bolt connection simplifies the construction process; the design of the connection device has wide adaptability and can be applied to a variety of prefabricated shear wall corner structures, and is easy to promote and apply in construction practice.

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0021] In the drawings, the same reference numerals all refer to the same components.

[0022] Example 1

[0023] like Figure 1-4 As shown, it includes a first fixing member 1 and a second fixing member 2. The first fixing member 1 includes two L-shaped first connecting blocks 3 facing opposite each other. One side of the first connecting block 3 is penetrated by a uniformly distributed first connecting hole 4. The vertical side of the first connecting block 3 is provided with two rows of uniformly distributed second connecting holes 5. The bottom of the two first connecting blocks 3 on the opposite side is provided with a connecting plate 6. The surface of the connecting plate 6 is provided with uniformly distributed third connecting holes 8. The second fixing member 2 includes two second connecting blocks 9. The top of the second connecting block 9 is provided with an additional block 10. The top of the additional block 10 is penetrated by a fourth connecting hole 11 with the same arrangement as the third connecting hole 8. A U-shaped block 12 is connected to the middle part of one side of the second connecting block 9, and the U-shaped block 12 half surrounds the second connecting block 9. A uniformly distributed and removable U-shaped plug-in 13 is provided between the U-shaped block 12 and the second connecting block 9. Two connecting frames 14 are provided between the two second connecting blocks 9. The two connecting frames 14 and the two second connecting blocks 9 jointly clamp the shear wall.

[0024] Furthermore, the third connecting hole 8 and the fourth connecting hole 11 are matched in size, and the third connecting hole 8 and the fourth connecting hole 11 are connected by bolts, so that the first fixing member 1 and the second fixing member 2 are fastened together.

[0025] The first connection hole 4 is connected to the shear wall by bolts, and the second connection hole 5 is connected to the shear wall by bolts.

[0026] The first fixing member 1 and the second fixing member 2 are both made of high-strength steel.

[0027] Specifically, during installation, first, the first fixing member 1 and the damaged shear wall are fastened and fitted together by using bolts to penetrate the first connecting hole 4 and the second connecting hole 5. This connection method ensures the firmness between the two. The first connecting block 3 is designed to protect and fix the lower second fixing member 2 to prevent it from being damaged by load deformation during use, thereby effectively extending its service life. In addition, the adopted envelope component design can provide better pressure and shear bearing capacity, significantly improving the protection performance of the component.

[0028] Step 2: The second fixing member 2 controls its connection position according to the fixed position of the upper structure. Once the position is determined, the second fixing member 2 fastens the first fixing member 1 and the second fixing member 2 through the third connection hole 8 and the fourth connection hole 11. In this way, the lower part of the protective device can be fixed in the correct working position, thereby completing the installation of the supporting structure. The connecting members on both sides adopt an external envelope design, which helps to better resist shear forces. The tightness of the fit can be adjusted through adjustable bolts to ensure that the protected shear wall can maintain overall stability under the action of external loads.

[0029] Step 3: Secure the U-shaped insert 13 to the outside of the second connecting block 9 via the U-shaped block 12. By semi-enclosing the second connecting block 9 with the U-shaped block 12, the U-shaped insert 13 can more effectively withstand and distribute the punching load from above. When the shear wall is subjected to load, its deformed shape can be adjusted to better protect the structure.

[0030] Step 4: After the second connecting blocks 9 are tightly connected, the connecting frame 14 links the second connecting blocks 9 symmetrically.

[0031] Finally, connect the corresponding bolts of each component to complete the installation of the entire component.

[0032] Working principle: Shear wall structures in buildings mainly bear vertical loads (such as deadweight, floor loads, etc.) and horizontal loads (such as wind loads, earthquake effects, etc.). Due to the particularity of its structure, L-shaped corner shear walls need to provide sufficient bending and shear resistance at the corners. When vertical loads act, the shear wall is subjected to shear force, and the prefabricated wall as a whole will be affected by a certain bending moment, and there is a certain possibility of overturning. The first fixing member 1 transmits the bending moment to the second fixing member 2 on the lower side through bolts. The overall structure redistributes the force acting on the entire structure, avoids stress concentration, and distributes the main part of the shear force to the U-shaped plug-in 13 and the U-shaped block 12. In addition, the connection nodes use high-strength bolts to connect the prefabricated components together. The high-strength bolts can withstand large tensile and shear forces to ensure the stability of the connection nodes under load. Under the action of horizontal load, the wall structure is likely to overturn. At this time, under the action of the connecting frame 14 protection device, the high-strength bolts at the connection of the connecting frame 14 connect the various nodes together to work together, so that the overall structure can fully disperse the force it is subjected to at the various nodes of the protection device under the action, and work together as a whole.

[0033] The connection mechanism of this device demonstrates remarkable flexibility and adaptability. The design of this energy-dissipating steel connection node concentrates the risk of structural damage and deformation at the U-shaped insert 13 and U-shaped block 12. After a natural disaster, these connection elements can be quickly repaired by simply removing and replacing the anchor bolts and through-wall bolts. This innovative design concept not only ensures that the connection node meets the specific strength and stability requirements in diverse application environments, but also significantly improves its adaptability and reliability in various engineering challenges, demonstrating its broad application potential and significant technological advancement in modern construction.

[0034] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
