[0001] The present application relates to the technical field of building engineering, and particularly relates to a steel plate connected energy dissipation infill wall. BACKGROUND

[0002] In actual engineering, in order to ensure the stability of the infill wall under the action of the earthquake, the rigid connection mode is generally used between the infill wall and the frame, and the common practice is to set a tie between the infill wall and the frame, however, the rigid connection mode increases the stiffness of the main structure, which leads to the increase of the seismic force, the frame column needs to bear more seismic force, and the risk of damage of the wall is increased, and the post-earthquake repair work is difficult.

[0003] In order to solve the adverse factors of the rigid connection in the earthquake, the concept of flexible connection and energy dissipation node is proposed. This connection mode allows a certain displacement or rotation between the infill wall and the frame by introducing a deformable element, thereby absorbing and dissipating the seismic energy and reducing the damage to the main structure. The flexible connection not only improves the overall seismic performance of the structure, but also facilitates the rapid repair and replacement of damaged parts after the earthquake.

[0004] The commonly used damping device adopts a metal damper, and the damper has a complex process and needs to be produced in a factory, has high cost, has large overall weight, has high precision requirement, and has large installation difficulty, and needs professional personnel to maintain, which is very troublesome. Therefore, it is necessary to research a steel plate connected energy dissipation infill wall. SUMMARY

[0005] In view of this, the purpose of the present application is to provide a steel plate connected energy dissipation infill wall, which effectively solves the problems of complex energy dissipation structure, high cost and large installation difficulty of the existing shock absorber.

[0007] Further, the pre-buried part comprises a pre-buried steel plate, and the pre-buried steel plate is distributed in the middle of one side of the infill wall along the horizontal direction.

[0008] Further, the upper and lower embedded steel plates are arranged in a staggered manner, the connecting part comprises an upper connecting plate, a lower connecting plate and an inclined plate, the upper and lower connecting plates are fixed at two ends of the inclined plate respectively and form a Z-shaped connecting part, and the upper and lower connecting plates are fixed on the upper and lower embedded steel plates correspondingly.

[0009] Further, a fixing rod is arranged on the upper and lower embedded steel plates, fixing holes are arranged on the upper and lower connecting plates, the fixing holes correspond to the fixing rod, and the connecting plates and the embedded steel plates are fastened together by applying bolts and gaskets.

[0010] Further, the connecting part further comprises a connecting plate and an energy dissipation body, the connecting plate is arranged at the connection between the inclined plate and the upper and lower connecting plates, the connecting plate is provided with a mounting hole, the energy dissipation body is assembled in the mounting hole through bolts, and adjacent connecting parts are combined to form an energy dissipation network.

[0011] Further, the energy dissipation body comprises a sleeve, a spring and a connecting rod, the connecting rod is assembled in the mounting hole through bolts, the connecting rod is sleeved in the sleeve through a limiting block, and the spring is sleeved in the sleeve and located between the two limiting blocks.

[0013] Further, bolt holes are arranged on the vertical steel plate, and the bolt holes are long circular holes in the vertical direction.

[0014] Further, soundproof and fireproof materials are filled in the gaps of the upper and lower infill walls.

[0015] The beneficial effects of the above technical solution are that the infill wall is internally embedded with a pre-embedded part, and the pre-embedded part provides a connection basis for the installation of the connecting part, in specific implementation, the infill wall uses steel plates as main energy dissipation materials, the structure is simple in material selection and convenient in construction, the construction cost is reduced, and the overall replacement and maintenance are convenient.

[0016] In energy dissipation, the deformation of the connecting part is mainly used as the energy dissipation basis, and in the specific structure, the energy dissipation steel plate has two implementation structures of inclination and verticality.

[0017] This invention sets up multiple sets of Z-shaped structures at intervals and configures them between the upper and lower infill walls to jointly resist the load.

DETAILED DESCRIPTION

[0035] The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0036] Example 1: This embodiment aims to provide a steel plate connected energy dissipation infill wall, mainly used for seismic energy dissipation of frame and infill wall. With the advancement of building industrialization, prefabricated assembly infill wall system has gradually become a trend. This system can realize standardized production, modular assembly, and rapid assembly with frame on site through dry connection technology (such as bolt connection, welding connection, etc.). This connection method not only simplifies the construction process, improves construction efficiency, but also reduces on-site wet work and reduces the impact of construction on the environment. At the same time, the prefabricated assembly infill wall system is easy to disassemble and replace, providing convenience for the renovation and upgrading of buildings. In view of the problems of complex energy dissipation structure, high cost and difficult installation of infill wall in the prior art, this embodiment provides a steel plate connected energy dissipation infill wall. When an earthquake occurs, buildings will be affected by seismic waves and vibrate. By utilizing the energy dissipation characteristics of steel plates, the energy generated by building vibration is absorbed and dissipated, thereby reducing the vibration amplitude of the building and protecting the building from earthquake damage.

[0037] For example, Figures 1-5As shown in the figure, a steel plate connecting energy dissipation infill wall comprises a frame column 1, an infill wall and an energy dissipation assembly. The infill wall is filled in the upper and lower parts of the frame column 1, i.e. comprising an upper infill wall 2 and a lower infill wall 3. The upper and lower infill walls are connected through the energy dissipation assembly. The left and right sides of the infill wall are filled with flexible filling material 7 in the gap of the frame column 1. In the embodiment, the flexible filling material 7 can be polyurethane. In the implementation, the upper and lower infill walls are connected through the energy dissipation assembly, and the left and right sides of the infill wall are filled with flexible filling material 7 in the gap of the frame column 1. Figure 1 As shown in the figure, the frame column 1 constitutes a square filling area as a whole. In the structure, the infill wall is arranged in the upper and lower parts of the filling area, and the energy dissipation area 4 is arranged in the middle. The two sides of the infill wall are filled with flexible filling material 7.

[0038] In the implementation structure, the energy dissipation assembly comprises a pre-buried part and a connecting part 6. The pre-buried part is pre-buried in one side of the infill wall. The connecting part 6 fixes and combines the upper and lower pre-buried parts together. The pre-buried part and the connecting part 6 are in a separate state in structure. The pre-buried part is pre-arranged in the infill wall.

[0039] In the implementation, the pre-buried part comprises a pre-buried steel plate 5. The pre-buried steel plate 5 is arranged in the one side of the infill wall in a spaced and centered manner along the horizontal direction. The back side of the pre-buried steel plate 5 is provided with a pull-out resistant tooth. The pre-buried steel plate 5 is pre-arranged in the infill wall in a factory prefabricated manner. The pre-buried steel plate 5 is exposed in structure and provides a fixed basis for the installation of the connecting part 6.

[0040] As an embodiment, the upper and lower pre-buried parts are arranged in a staggered manner. The connecting part 6 comprises an upper connecting plate 61, a lower connecting plate 63 and an inclined plate 62. The upper connecting plate 61 and the lower connecting plate 63 are respectively fixed at the two ends of the inclined plate 62 and form a Z-shaped connecting part 6. The upper connecting plate 61 and the lower connecting plate 63 are respectively fixed on the upper and lower pre-buried steel plates 5.

[0041] The Z-shaped connecting part 6 can be formed by one-piece bending, of course, it can also be formed by welding combination. The upper connecting plate 61 and the lower connecting plate 63 are both horizontal structures. The inclined plate 62 is an inclined structure and combines the upper connecting plate 61 and the lower connecting plate 63 together. In the combined structure, the upper connecting plate 61 and the lower connecting plate 63 are respectively fixed on the pre-buried steel plate 5 in a corresponding and matching manner, so that the upper and lower infill walls are combined together through the connecting part 6 and form an energy dissipation space between the upper and lower infill walls. When an earthquake occurs, the upper and lower energy dissipation walls can move to the energy dissipation space, resist external load through the deformation of the connecting part 6 and dissipate the horizontal force generated by the earthquake.

[0042] The gap between the upper infill wall 2 and the lower infill wall 3 is filled with sound insulation and fireproof material, so as to fill the energy dissipation space and have good sound insulation and fireproof effect, thereby improving the overall aesthetic appearance.

[0043] Working principle description; in the working process of the embodiment, the embedded steel plate 5 is pre-reserved on the lower side of the upper infill wall and the upper side of the lower infill wall, the embedded steel plate 5 is exposed, spaced and horizontally arranged on the corresponding infill wall, which can be used as the energy dissipation support base of the infill wall, then the Z-shaped connecting part 6 is arranged in the energy dissipation space, the upper connecting plate 61 is fixedly connected with the upper embedded steel plate 5, the lower connecting plate 63 is fixedly connected with the lower embedded steel plate 5, and the inclined plate 62 is supported, and the load is resisted by the connection strength of the inclined plate 62 and the upper and lower connecting plates.

[0044] When encountering the earthquake force, the main energy dissipation deformation part in the embodiment is concentrated in the inclined plate 62. The deformation here includes two aspects, one is the shape change of the inclined plate 62 itself, and the other is the self-deformation caused by the internal structure. Due to the unique Z-shaped structure of the connecting part 6, when resisting the load, on the one hand, it relies on the deformation characteristics of the material itself, and on the other hand, it relies on the unique shape change of the Z-shaped structure to disperse and absorb the energy brought by the horizontal load.

[0045] The embodiment mainly aims at the earthquake load. When the earthquake occurs, the building will inevitably be affected by the strong earthquake wave and will produce violent vibration. The embodiment makes full use of the excellent energy dissipation characteristics of the steel plate, and quickly and efficiently absorbs and consumes the energy generated in the vibration process of the building. In this way, the vibration amplitude of the building is significantly reduced, and a strong defense line is built for the building, so that the destructive influence of the earthquake can be reduced, and the structural safety and stability of the building can be maximized. The embodiment uses steel plate as the main energy dissipation material, the structure is simple to take, the construction is convenient, the construction cost is reduced, and the overall replacement and maintenance are convenient.
