Description

Technical Field

[0001] This utility model relates to the field of building structures, specifically to an earthquake-resistant connection structure for building structures. Background Technology

[0002] Earthquakes are a relatively common natural disaster caused by geological activity within the Earth's crust. They can release enormous amounts of energy in a short period of time. When an earthquake occurs, seismic waves propagate through the Earth's crust, posing a significant threat to buildings.

[0003] Typically, longitudinal seismic waves are felt first, as they travel faster and primarily cause vertical ground shaking. Lateral seismic waves arrive subsequently; they travel slower but have larger amplitudes, mainly causing horizontal ground shaking. Sector waves are particularly damaging to buildings because they cause horizontal swaying, leading to structural damage or even collapse.

[0004] Traditional monolithically cast load-bearing walls, due to their high rigidity, lack sufficient elasticity or deformation capacity to effectively absorb energy and mitigate the impact of earthquakes when encountering lateral seismic waves. This allows the energy of the earthquake to be directly transmitted to the building structure, reducing the time that the building remains stable during an earthquake and shortening the time for people to safely escape from the building.

[0005] Therefore, a seismic connection structure for building structures is needed to solve the above problems. Utility Model Content

[0006] Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides an earthquake-resistant connection structure for building structures, solving the problem mentioned in the background art that traditional monolithically cast-in-place load-bearing walls, due to their high rigidity, lack sufficient elasticity or deformation capacity to effectively absorb energy and mitigate the impact of earthquakes when encountering lateral seismic waves.

[0008] Technical solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a seismic-resistant connection structure for building structures, comprising a load-bearing main body, a buffer layer, a connecting structure, and a decorative layer. The load-bearing main body comprises two sets of walls, with a buffer layer disposed between the two sets of walls. The two sets of walls are connected by a connecting structure, and a decorative layer is disposed on the outer side of the two sets of walls. The walls include a structural steel mesh. The connecting structure includes connecting steel bars, both ends of which are fixed to the structural steel mesh. The buffer layer includes a buffer perforated plate, which is disposed between the two sets of reinforcing steel mesh. There are multiple sets of buffer perforated plates, and connecting holes are formed on the buffer perforated plates. The connecting steel bars are disposed inside the connecting holes, and the diameter of the connecting holes is larger than that of the connecting steel bars. Concrete is poured on the outer side of the structural steel mesh.

[0010] Preferably, the buffer perforated plate is made of rigid foam plastic.

[0011] Preferably, the upper ends of the two sets of structural steel reinforcement mesh are fixed to the upper floor slab.

[0015] Beneficial effects

[0016] This utility model provides a seismic-resistant connection structure for building structures, which has the following beneficial effects: In practical use, the traditional monolithic cast-in-place load-bearing wall is divided into two independent wall groups, with multiple layers of perforated buffer plates installed between them as a buffer layer. Connecting steel bars are used to connect the two wall groups. This not only enhances the overall strength and stability of the wall, but more importantly, it can significantly absorb and disperse the energy of seismic waves during an earthquake. By allowing relative movement between the walls and the torsional deformation of the connecting steel bars, it mitigates the seismic impact, thereby effectively extending the building's stabilization time during an earthquake and providing more valuable time for people to escape safely.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: an anti-seismic connection structure for building structures, including a load-bearing main body 1, a buffer layer 2, a connecting structure 3, and a decorative layer 4. The load-bearing main body 1 includes two sets of walls 11, with a buffer layer 2 between the two sets of walls 11 and the two sets of walls 11 connected by the connecting structure 3. A decorative layer 4 is provided on the outer side of the two sets of walls 11. The walls 11 include a structural steel mesh 111. The connecting structure 3 includes connecting steel bars 31, with both ends of the connecting steel bars 31 fixed to the structural steel mesh 111. The buffer layer 2 includes a buffer perforated plate 21, which is set between the two sets of steel mesh. There are multiple sets of buffer perforated plates 21. A connecting hole 22 is opened on the buffer perforated plate 21, and the connecting steel bars 31 are set inside the connecting hole 22. The diameter of the connecting hole 22 is larger than that of the connecting steel bars 31. Concrete 112 is poured on the outer side of the structural steel mesh 111.

[0025] During use, the structural steel mesh 111 enhances the overall strength and stability of the wall 11. Pouring concrete encases the connecting steel bars 31 of the structural steel mesh 111, forming a unified structure. The decorative layer 4 provides aesthetic enhancement and protection for the building's appearance. The connecting steel bars 31 are fixed at both ends to the structural steel mesh 111, ensuring the overall stability of the wall 11. During an earthquake, lateral waves cause the two sets of walls 11 to shake, forcing the connecting steel bars 31 in the middle to twist and deform. This deformation process dissipates seismic energy, providing damping and buffering effects. The design of the connecting holes 22 ensures that the connecting steel bars 31 are not obstructed during concrete pouring, allowing the concrete to evenly fill around the connecting steel bars 31, forming a tight enclosure.

[0026] The buffer perforated board 21 is made of rigid foam plastic. The rigid foam plastic buffer perforated board 21 serves as a partition, dividing the load-bearing wall, which may have been cast as a whole, into two independent wall parts 11.

[0027] The upper ends of the two sets of structural steel mesh 111 are fixed to the upper floor slab 6. The structural steel mesh 111 is the skeleton of the wall 11, and the structural steel mesh 111 ensures a firm connection with the upper floor slab 6.

[0028] A moisture-proof coating 5 is provided on the outside of the wall 11. The main function of the moisture-proof coating 5 is to prevent the wall 11 from being affected by moisture, water and the resulting erosion and damage.

[0029] The decorative layer 4 includes a crack-resistant mesh 41, which is located on the outside of the moisture-proof coating 5. Latex paint 42 is applied to the outside of the crack-resistant mesh 41. The crack-resistant mesh 41, the moisture-proof coating 5, and the latex paint 42 together form a complete protective system, which not only improves the durability and stability of the wall 11, but also ensures the aesthetics and practicality of the building's appearance.

[0030] A steel bar wrapping layer 32 is provided on the outside of the connecting steel bar 31. The steel bar wrapping layer 32 is made of cast concrete 112. The steel bar wrapping layer 32 also has certain anti-corrosion and durability properties, which can extend the service life of the connecting steel bar 31.

[0031] As an embodiment of this utility model: When an earthquake occurs in the seismic connection structure 3 used in building structures, the two sets of walls 11 will first shake relative to each other when the transverse wave acts on the building structure. Since the two ends of the connecting steel bars 31 in the connection structure 3 are fixed to the structural steel mesh 111, this shaking will force the connecting steel bars 31 to twist and deform. The flexible design of the connecting steel bars 31 enables them to absorb and disperse energy in the earthquake, playing a damping and buffering effect, thereby reducing the direct impact of the earthquake on the walls 11. It can significantly absorb and disperse the energy of seismic waves, and mitigate the earthquake impact by allowing relative movement between the walls 11 and the twisting deformation of the connecting steel bars 31, thereby effectively extending the stability time of the building in the earthquake and providing more valuable time for people to escape safely.
