Description

Technical Field

[0001] This invention relates to the field of seismic resistance technology for building structures, specifically to a prefabricated, shock-absorbing, lightweight composite infill wall panel structure. Background Technology

[0002] Past earthquake damage has shown that infill walls, which are rigidly connected to the reinforced concrete main structure and considered as non-structural components, actually participate in the distribution of seismic shear force in the structure. At the same time, due to the inherent problems of uncontrollable stiffness, poor ductility, and low energy dissipation capacity of infill walls, they are prone to cracking, damage, and collapse under earthquake action, and may even cause serious damage and collapse of the structure.

[0003] Actual engineering practice has revealed that although the infill walls are designed with a flexible connection to the main structure, theoretically eliminating the interaction between the infill walls and the main structure, which is consistent with the current design code's calculation assumption that infill walls are treated as non-structural components, in reality, due to the lack of an effective connection between the infill walls and the main structure, they are prone to collapse due to out-of-plane instability during earthquakes.

[0004] These issues require that the infill walls not only have the function of dividing the frame space, but also have a certain degree of deformation and energy dissipation capacity, as well as good integrity and the ability to be quickly repaired.

[0005] Meanwhile, existing concrete structures, including infill walls and main structures, are susceptible to damage and destruction during earthquakes. Furthermore, the most widely used prefabricated lightweight wall panel enclosure components have also revealed shortcomings and problems in terms of installation and earthquake resistance.

[0006] Firstly, it has almost no seismic resistance on its own; secondly, it cannot provide energy-dissipating defenses for the main frame structure or improve the overall seismic performance of the structure; and thirdly, the walls are large in volume, heavy in weight, and difficult to install. Summary of the Invention

[0061] Example 1

[0062] Actual engineering practice has revealed that although the infill walls are designed with a flexible connection to the main structure, theoretically eliminating the interaction between the infill walls and the main structure, which is consistent with the current design code's calculation assumption that infill walls are treated as non-structural components, in reality, due to the lack of an effective connection between the infill walls and the main structure, they are prone to collapse due to out-of-plane instability during earthquakes.

[0063] Therefore, this invention provides a prefabricated, shock-absorbing, lightweight composite infill wall panel structure that is lightweight, easy to install in sections, has controllable stiffness, and provides energy dissipation and shock absorption. It is deformable and energy-dissipating in the plane, and constrained by the main structure out of the plane, solving the problems of unquantifiable stiffness and energy dissipation capacity of existing masonry infill walls, as well as the large weight, poor connection stability, and poor reliability of existing prefabricated infill walls.

[0064] like Figure 1 and Figure 2 As shown in the figure, this embodiment provides a prefabricated shock-absorbing lightweight composite infill wall panel structure. The infill wall panel is set inside the structural frame and is fixedly connected to the structural frame through connecting embedded parts.

[0065] The structural frame includes structural columns 1 and structural beams 2, which form the main structure of the infill wall and are used to install composite wall panels.

[0066] For ease of description, the structural beam 2 is defined as an upper structural beam 2a and a lower structural beam 2b, with the upper structural beam 2a positioned directly above the lower structural beam 2b, and the structural column 1 is defined as having a left side and a right side.

[0067] The composite wall panel includes an upper composite wall panel 3a and a lower composite wall panel 3b. The upper end of the upper composite wall panel 3a is fixedly connected to the upper structural beam 2a, and the lower end of the lower composite wall panel 3b is fixedly connected to the lower structural beam 2b.

[0068] The lower composite wall panel 3b is positioned directly below the upper composite wall panel 3a. The lower end of the upper composite wall panel 3a is fixedly connected to the upper end of the lower composite wall panel 3b. The upper composite wall panel 3a and the lower composite wall panel 3b constitute an integral composite wall panel.

[0069] The connecting embedded parts include composite wall embedded parts 4 and structural beam embedded parts 5.

[0070] like Figure 3 As shown, the structural beam embedded part 5 is pre-embedded in the structural beam 2. The structural beam embedded part 5 includes an upper structural beam embedded part 5a and a lower structural beam embedded part 5b. The upper structural beam embedded part 5a is pre-embedded on the bottom surface of the upper structural beam 2a, and the lower structural beam embedded part 5b is pre-embedded on the top surface of the lower structural beam 2b. In this embodiment, both the upper structural beam embedded part 5a and the lower structural beam embedded part 5b are T-shaped connectors, and their vertical sections are pre-embedded in the upper structural beam 2a and the lower structural beam 2b.

[0071] The composite wall embedded part 4 is pre-embedded in the composite wall panel. The composite wall embedded part 4 includes an upper composite wall embedded part 4a and a lower composite wall embedded part 4b. The upper composite wall embedded part 4a is pre-embedded on the upper end face of the upper composite wall panel 3a, and the lower composite wall embedded part 4b is pre-embedded on the lower end face of the lower composite wall panel 3b. The upper composite wall embedded part 4a and the lower composite wall embedded part 4b are snap-fit, snap-plate or snap-slot structures adapted to the crossbar sections of the upper structural beam 2a embedded part and the lower structural beam 2b embedded part. The position of the composite wall panel is fixed by connecting with the crossbar.

[0072] The upper composite wall embedded part 4a is correspondingly and fixedly connected to the upper structural beam 2a embedded part; the lower composite wall embedded part 4b is correspondingly and fixedly connected to the lower structural beam 2b embedded part.

[0073] In addition, the upper composite wall panel 3a and the lower composite wall panel 3b are fixedly connected by a metal energy-dissipating connector 3c. This metal energy-dissipating connector 3c is a metal connector with a certain degree of elasticity and plasticity. When the upper composite wall panel 3a and the lower composite wall panel 3b undergo tangential displacement, the metal energy-dissipating connector 3c can achieve the function of shock absorption and energy dissipation, and has good deformation capacity. In order to further improve the shock absorption performance, the reinforced concrete slab, blocks and ribs in the upper composite wall panel 3a and the lower composite wall panel 3b are destroyed in sequence to provide energy dissipation.

[0074] The flexible filling material component 6 is a flexible thermal insulation and waterproof filling component. When the wall panel undergoes lateral deformation under seismic action, it does not collide with the main structure in the plane, and its influence on the lateral stiffness of the main structure can be quantified.

[0075] Example 2

[0076] This embodiment refers to the structure of Embodiment 1, such as Figure 2 , Figure 3 , Figure 4 As shown, this further improves the seismic performance and lightweighting of the upper composite wall panel 3a and the lower composite wall panel 3b.

[0077] The upper composite wall panel 3a includes the rear upper composite wall panel 3a2 and the front upper composite wall panel 3a1.

[0078] The front upper composite wall panel 3a1 is the main base plate, and the entire upper composite wall panel 3a is installed by embedding the rear upper composite wall panel 3a2 into the front upper composite wall panel 3a1.

[0079] The front upper composite wall panel 3a1 has an upper groove on its front side in the wall thickness direction that is adapted to the rear upper composite wall panel 3a2, and the rear upper composite wall panel 3a2 is fixedly installed in the upper groove.

[0080] The lower composite wall panel 3b includes a rear lower composite wall panel 3b2 and a front lower composite wall panel 3b1, the structure of which is similar to that of the upper composite wall panel 3a and will not be described in detail. The front side of the front lower composite wall panel 3b1 has a groove in the wall thickness direction that is adapted to the rear lower composite wall panel 3b2, and the rear lower composite wall panel 3b2 is fixedly installed in the groove.

[0081] During installation, the front upper composite wall panel 3a1 and the front lower composite wall panel 3b1 are first installed in their corresponding positions, and then the rear upper composite wall panel 3a2 and the rear lower composite wall panel 3b2 are installed in the upper and lower grooves, respectively. Therefore, the lower end face of the front upper composite wall panel 3a1 and the upper end face of the front lower composite wall panel 3b1 are fixedly connected by a metal energy-dissipating connector 3c. The bottom of the upper groove is provided with a front and rear composite wall panel fixing assembly 3d for connecting the rear upper composite wall panel 3a2; the bottom of the lower groove is provided with a front and rear composite wall panel fixing assembly 3d for connecting the rear lower composite wall panel 3b2.

[0082] The front upper composite wall panel 3a1 and the rear upper composite wall panel 3a2 can be installed using the front and rear composite wall panel fixing components 3d, as well as the front lower composite wall panel 3b1 and the rear lower composite wall panel 3b2.

[0083] Example 3

[0084] like Figure 3 As shown in the figure, this embodiment describes the specific structure of the upper composite wall panel 3a and the lower composite wall panel 3b.

[0085] The front upper composite wall panel 3a1 / front lower composite wall panel 3b1 includes a front rib column, a front rib beam and a front reinforced concrete slab.

[0086] Two vertically positioned front ribs and two horizontally positioned front ribs form a rectangular frame structure, with the front reinforced concrete slab fixedly positioned within the rectangular frame structure.

[0087] The front ribs and front rib beams are made of concrete, which provides greater strength. The front reinforced concrete slab is a thin reinforced concrete slab, which can effectively reduce the weight of the wall panel.

[0088] The upper rear composite wall panel 3a2 and the lower rear composite wall panel 3b2 are made of blocks or autoclaved aerated concrete (ALC) masonry panels.

[0089] In addition, in order to embed the upper rear composite wall panel 3a2 into the upper front composite wall panel 3a1 and the lower rear composite wall panel 3b2 into the lower rear composite wall panel 3b2, an upper groove and a lower groove are added in Embodiment 2.

[0090] In this embodiment, the upper groove is achieved by protruding front ribs and front rib beams. During casting, the front ribs and front rib beams, which are rectangular in structure on the outer side, are cast protrudingly.

[0091] As shown, the thickness of the front ribs on the left and right sides is equal to the thickness of the upper composite wall panel 3a, the thickness of the front rib beams on the upper and lower sides is equal to the thickness of the upper composite wall panel 3a, the thickness of the front reinforced concrete slab is equal to n / m of the thickness of the upper composite wall panel 3a, and the depth of the upper groove, the block or autoclaved aerated concrete masonry ALC slab is equal to 1-n / m of the thickness of the upper composite wall panel 3a.

[0092] Both n and m are natural numbers, n < m, and it is best if n = 1 and m = 4.

[0093] The depth of the lower groove is equal to the depth of the upper groove, so that after the upper composite wall panel 3a2 is embedded into the upper groove, the lower composite wall panel 3b2 can be perfectly identified, avoiding structural protrusion.

[0094] In addition, this embodiment provides a specific 3D structure of the front and rear composite wall panel fixing assembly, which includes embedded rods and embedded holes.

[0095] Two embedded rods are fixed at the junction of the front rib and the front rib beam. The embedded rods are fixed to the concrete rib beam and rib, which can increase stability.

[0096] Two pre-embedded holes, which are fixedly installed on the top or bottom surface of the upper rear composite wall panel 3a2 / lower rear composite wall panel 3b2 and are compatible with the pre-embedded rods, are provided on the concrete-cast rib beams and rib columns to increase stability.

[0097] By fixing the embedded rods and embedded holes together, the connection between the upper composite wall panel 3a and the lower composite wall panel 3b is achieved.

[0098] Meanwhile, the above-mentioned embodiments can achieve the effect of vibration reduction and energy dissipation of composite wall panels under small, moderate and large earthquakes, and have good deformation capacity.

[0099] At the same time, it can effectively prevent the wall panels from being damaged in the case of minor and moderate earthquakes, and can play a supporting role in the case of major earthquakes to prevent the wall from collapsing, thus achieving the effect of energy dissipation and shock reduction.

[0100] The vertical joint between the composite wall panel and structural column 1 is filled with a flexible thermal insulation and waterproof filling component, so that when the wall panel undergoes lateral deformation under seismic action, it does not collide with the main structure in the plane, and its influence on the lateral stiffness of the main structure can be quantified. The wall panel is fixed to the upper and lower structures outside the plane, so the stress on the structure is clear and the force transmission path is clear, ensuring the reliability of the structure.

[0101] Example 4

[0102] This embodiment provides a prefabricated wall, including a prefabricated shock-absorbing lightweight composite infill wall panel structure as described above. Two or more infill wall panels 3 are connected in parallel by interlocking grooves, and a flexible filling material component 6 is filled between two adjacent infill wall panels 3. The interlocking grooves enable a detachable fixed connection.

[0103] In addition, the composite wall panels in the above embodiments can be used in combination with the sliding prefabricated infill wall panels 7, and the vertical gaps between them are filled by flexible thermal insulation and waterproof filling components. The sliding prefabricated wall panels are slidably connected to the upper structural beam 2a or the lower structural beam 2b via sliding fasteners 7a.
