Description

Technical Field

[0001] This utility model relates to the field of building wall technology, specifically to a prefabricated energy dissipation infill wall. Background Technology

[0002] In traditional building structures, infill walls (usually constructed of blocks, bricks, or lightweight concrete slabs) primarily serve as enclosures and partitions. However, actual earthquake damage surveys and studies have shown that although these conventional infill walls are non-structural components, they still have the following drawbacks:

[0003] (1) When the infill wall is in close contact with the surrounding beams, columns and other main structures (frame or frame-shear structure), it usually has high in-plane shear stiffness and strength, which leads to a significant increase in the lateral stiffness of the overall structure, a shortened natural vibration period, and a significantly greater seismic effect than the design expectation, thus exacerbating the structural burden.

[0004] (2) The constraint effect (especially the short column effect) forces the main structural components (such as columns, beam ends, and nodes) to bear complex shear forces and constraint moments far exceeding their design bearing capacity, which can easily lead to brittle shear failure. This type of failure mode has poor ductility and low energy dissipation capacity, and is an important factor in structural instability or even collapse.

[0005] (3) The infill wall itself does not have effective and controllable energy dissipation and shock absorption capabilities. Its damage in earthquakes (such as X-shaped diagonal cracks) is often sudden and brittle, and it cannot provide the expected ductile energy dissipation support for the main structure. Instead, it may cause secondary disasters due to damage and fall off.

[0006] (4) Traditional infill walls and shock absorber supports are constructed using on-site wet masonry methods, which have problems such as long construction cycles and environmental pollution, and are in conflict with the current policy advocating the industrialization and green development of prefabricated buildings.

[0007] Therefore, existing technologies need to be improved. Utility Model Content

[0008] This utility model aims to provide a prefabricated energy-dissipating infill wall, which achieves factory prefabrication and on-site assembly through modular design. At the same time, through energy-dissipating connection device and flexible structural design, it reduces interference with the stiffness of the main structure while meeting the enclosure function, realizes controllable energy dissipation under vibration, avoids brittle failure of the main structure, and meets the development needs of prefabricated buildings.

[0009] This utility model is achieved through the following technical solution:

[0010] This utility model provides a prefabricated energy-dissipating infill wall, which includes structural beams, including an upper structural beam and a lower structural beam. A structural column is provided between the upper structural beam and the lower structural beam. Lightweight infill wall panels and composite wall panels are provided within the frame formed by the structural column, the upper structural beam, and the lower structural beam. The composite wall panels include an upper composite panel connected to the upper structural beam and a lower composite panel connected to the lower structural beam. An energy-dissipating connection device is provided between the upper composite panel and the lower composite panel.

[0011] Furthermore, in this utility model, the energy-consuming connection device described above is configured as a friction damper or a viscous damper, with one end of the horizontally arranged energy-consuming connection device connected to the upper composite plate and the other end connected to the lower composite plate.

[0012] Furthermore, in this utility model, a flexible filling layer is provided between the upper composite panel and the lower composite panel, between the lightweight infill wall panel and the composite wall panel, and between the lightweight infill wall panel or the composite wall panel and the structural column.

[0013] Furthermore, in this utility model, a lower hanging plate is provided at the bottom of the upper structural beam, and the lower hanging plate is connected to the upper composite plate.

[0014] Furthermore, in this utility model, the above also includes a composite plate connector, wherein the upper composite plate is connected to the lower hanging plate through the composite plate connector, and the lower composite plate is connected to the lower structural beam through the composite plate connector.

[0015] Furthermore, in this utility model, the above also includes structural connectors, through which the upper composite plate and the lower hanging plate are connected, and through which the lower composite plate and the lower structural beam are connected.

[0016] Furthermore, in this utility model, the composite wall panel mentioned above includes a panel, and wall panel ribs and wall panel ribs are provided between the panels, forming a cavity layer between the wall panel ribs, the wall panel ribs and the panel.

[0017] Furthermore, in this utility model, the aforementioned wall panel ribs and the panel are configured as reinforced concrete structures or steel-concrete composite structures.

[0018] Furthermore, in this invention, the cavity layer described above is configured as an air layer, a polystyrene board, or a gypsum board.

[0019] Furthermore, in this invention, the aforementioned cavity layer is configured as a cement fiberboard, a calcium silicate board, or a masonry block.

[0020] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0021] (1) Strong energy dissipation capacity: The structure can actively and efficiently dissipate earthquake input energy under earthquake action;

[0022] (2) Avoid brittle failure: Through the energy dissipation connection device and the flexible connection between the wall panels, the "short column effect" caused by the traditional rigid connection and the rigid constraint on the rotation of the beam end can be effectively eliminated, significantly reducing the risk of brittle shear failure of the main structure (especially the column) and ensuring the overall ductility and collapse resistance of the structure;

[0023] (3) Lightweight (the presence of the cavity layer makes the composite wall panel lightweight), heat insulation and sound insulation (the composite wall panel itself has building functions such as heat insulation and sound insulation); the two sides of the infill wall panel are flat and integrated with the building;

[0024] (4) Prefabricated production and installation improve the level of industrialization and construction efficiency, ensure the consistency and reliability of product quality, and the dry operation method simplifies the construction process and reduces pollution and material waste caused by wet operation on site.

[0035] Example 1

[0036] This embodiment provides a prefabricated energy dissipation infill wall, such as Figures 1-3 As shown, the specific structure is described below.

[0037] Combination Figure 1 As shown, the prefabricated energy dissipation infill wall in this embodiment mainly includes structural beams 1, structural columns 2, lightweight infill wall panels 3, composite wall panels 4, and energy dissipation connection devices 6, etc.

[0038] Structural beam 1: Includes upper structural beam 101 and lower structural beam 102, both of which are original components of the frame structure. The bottom of the upper structural beam 101 is fixed to the lower hanging plate 5 by means of rebar anchoring. The lower hanging plate 5 is a cast-in-place concrete slab with the same thickness as the upper structural beam 101 and its length extends to the top of the composite wall panel 4. The construction height of the lower hanging plate 5 is adjustable. When the height of the composite wall panel 4 is a standard size with a certain gradient change, the change of the structural floor height can be further adjusted by the height of the lower hanging plate 2.

[0039] Structural column 2 is an existing component of the frame structure. An expansion joint of about 50~100mm is reserved between the inner side of structural column 2 and the lightweight infill wall panel 3 or composite wall panel 4. The joint is filled with a flexible filling layer 9, such as rock wool or foamed concrete board.

[0040] Lightweight infill wall panel 3: The lightweight infill wall panel 3 is neatly installed between the upper structural beam 101 and the lower structural beam 102. An expansion joint of about 50~100mm is reserved between the lightweight infill wall panel 3 and the composite wall panel 4. The joint is filled with a flexible filling layer 9 such as rock wool, foamed concrete board, etc.

[0041] Composite wall panel 4: Combination Figure 3 , Figure 4 and Figure 5 As shown, the system includes an upper composite panel 401 and a lower composite panel 402. Each upper composite panel 401 or lower composite panel 402 comprises three parts: a panel 12, wall panel ribs 10, and wall panel ribs 11. The cavity layer 13 is the space between the panel 12, wall panel ribs 10, and wall panel ribs 11, and can be filled with polystyrene board, gypsum board, cement fiberboard, calcium silicate board, or masonry blocks. The cavity layer 13 can also be left unfilled as an air layer. If it is an air layer, it can be formed by casting a layer of wooden formwork on the cavity layer 13; if it is made of other materials, it can be cast by placing the cavity layer 13 material as a formwork.

[0042] Energy-consuming connection device 6: Employs a friction damper, combined with Figure 2 and Figure 3 As shown, the energy dissipation connection device 6 is fixedly connected to the upper composite plate 401 and the lower composite plate 402 respectively through composite plate connectors 7. The seismic action causes the structure and composite wall panel 4 to generate displacement or acceleration, which in turn drives the energy dissipation connection device 3, such as a friction damper that dissipates energy through sliding friction or a viscous damper that dissipates energy through viscous damping.

[0043] Connectors and Flexible Filler Layer 9: Composite panel connector 7 is an embedded part installed in composite wall panel 4, and structural connector 8 is an embedded part installed in lower hanging plate 5 or structural beam 1. Composite panel connector 7 is used to connect with structural connector 8, and the connection between the two embedded parts can be by welding or bolting. Composite panel connector 7 is also used for fixed connection with energy dissipation connection device 6.

[0044] The gap between the upper composite panel 401 and the lower composite panel 402 is filled with a flexible filling layer 9, such as rock wool, cement fiberboard, foamed concrete board, etc.

[0045] When a vibration occurs, the prefabricated energy-dissipating infill wall in this embodiment dissipates seismic energy and reduces seismic action, thereby protecting the structural safety.

[0046] Example 2

[0047] This embodiment provides a prefabricated energy-dissipating infill wall, with the remaining components unchanged. The energy-dissipating connection device 6 and the composite wall panel 4 are as follows: Figures 4-6 As shown.

[0048] Among them, the energy-consuming connection device 6 is a viscous damper.

[0049] The composite wall panel 4 differs from that in Example 1 in that it has a middle diagonal rib between the horizontal wall panel rib beams 10 and the vertical wall panel ribs 11 at the edge, and a cavity layer 13 between the horizontal wall panel rib beams 10, the vertical wall panel ribs 11, the diagonal wall panel ribs 11 and the panel 12.

[0050] This is because the output of the viscous damper varies over a large range. At high tonnage outputs, the transverse wall panel ribs 10 and vertical wall panel ribs 11 at the edge of the composite wall panel 4 are insufficient to effectively resist the principal tensile stress within the composite wall panel 4, potentially leading to the appearance and propagation of diagonal cracks. Therefore, diagonal reinforcement is specifically configured as a shear-strengthening measure to provide a clear force transmission path for the diagonal force generated by the viscous damper, ultimately effectively diffusing from the viscous damper connecting plate through the composite wall panel 4 to the main load-bearing components such as the structural beams 1 and columns.

[0051] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
