Abstract
Description
Technical Field
[0001] This invention relates to a prefabricated shock-absorbing composite infill wall, and more particularly to a prefabricated shock-absorbing composite infill wall with a sealable energy-dissipating damping component. Background Technology
[0002] To complement building functions, vibration damping devices often incorporate energy-dissipating damping components between upper and lower cantilever walls within a frame, such as wall-type viscous dampers and rod-type viscous dampers (wall-type structures). Another example is a prefabricated, lightweight composite infill wall panel structure disclosed in Chinese patent CN218292374U. This wall panel structure includes upper and lower composite infill wall panels within a frame, as well as energy-dissipating damping components between the composite infill wall panels. Under seismic action, the upper and lower composite infill wall panels and the energy-dissipating damping components deform within the frame plane to absorb energy and reduce vibration, thereby minimizing the interaction between the frame structure and the composite infill wall panels.
[0003] This structure, featuring cantilever wall panels and energy-dissipating damping components, integrates the partitioning function of the building wall with the energy dissipation and vibration reduction function of the structure, thus mitigating the impact of vibration reduction devices on building functionality to a certain extent. However, it still has the following shortcomings: First, the energy-dissipating damping components are exposed to the external environment, affecting aesthetics and increasing the risk of damage and failure (such as oxidation and corrosion); or embedding the energy-dissipating damping components in the wall makes inspection, maintenance, and replacement difficult. Second, the gaps in the energy-dissipating damping component area make it difficult to apply the outer surface finish of the structure, and also prevent the structure from fully realizing its waterproofing, insulation, fireproofing, and corrosion resistance functions, thus making it unsuitable for use in building exterior walls, bathrooms, kitchens, basements, and other similar locations. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a prefabricated shock-absorbing composite infill wall with a sealable energy-dissipating damping component that is fireproof, corrosion-resistant, waterproof, heat-insulating, and sound-insulating.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: The prefabricated vibration-damping composite infill wall includes a structural frame, composite infill wall panels, lightweight infill wall panels, and energy-dissipating damping components. The composite infill wall panels and lightweight infill wall panels are installed within the structural frame. The composite infill wall panels are connected to the structural frame via embedded connecting parts. Lightweight infill wall panels are located on both sides of the composite infill wall panels. The structural frame includes frame columns and frame beams. The composite infill wall panels include an upper composite infill wall panel and a lower composite infill wall panel. An energy-dissipating damping component connects the upper and lower composite infill wall panels. The thickness of the energy-dissipating damping component is less than the thickness of the composite infill wall panel. A slidable connecting device is installed on one side of the outer side of the energy-dissipating damping component. The slidable connecting device includes a cover plate, a groove, and a rail. The groove and rail are located inside the cover plate. The rail is nested in the groove inside the cover plate and is fixedly connected to the embedded steel plate or embedded reinforcing bar at the bottom of the upper composite infill wall panel. A sliding gap is left between the end of the slide rail, the end of the slide groove, and the cover plate. The sliding gap is not less than the width of the gap between the composite infill wall panel and the frame column. The cover plate can slide laterally on the slide rail through the slide groove, or rotate circumferentially around the axis of the slide rail.
[0006] In the above technical solution, a locking device is installed at the lower part of the cover plate. The locking device has a switch to control the extension and retraction of the locking tongue. A baffle strip is provided between the locking tongue and the cover plate. The baffle strip is fixedly connected to the upper end of the lower composite infill wall plate by a pre-embedded steel plate or pre-embedded reinforcing bar. When the cover plate is closed, the control switch causes the locking tongue to extend out of the locking device to prevent the cover plate from rotating; when the cover plate is open, the control switch causes the locking tongue to retract into the locking device.
[0007] In the above technical solution, the energy-dissipating damping component has a waterproof layer on the water-facing side. This waterproof layer can be composed of lightweight thermal insulation mortar and its double-sided waterproof coating, or a composite waterproof mortar. The double-sided waterproof coating of the lightweight thermal insulation mortar uses epoxy or modified epoxy coatings as sealing materials, or cement-based or silicone (siloxane) penetrating materials; the composite waterproof mortar uses cement-based composite waterproof mortar or polymer cement waterproof mortar, both of which possess good corrosion resistance.
[0008] In the above technical solution, there is a filling material layer between the waterproof layer of the damping component and the energy-dissipating damping component, and there is a filling material layer between the energy-dissipating damping component and the sliding connection device. The filling material layer is composed of heat-insulating, sound-insulating and fire-resistant functional filling materials, such as rock wool, pearl cotton, flame-retardant rubber and plastic sponge, glass wool, or combinations thereof, or it can be left empty.
[0009] In the above technical solution, the composite infill wall panel and the energy-dissipating damping component have an externally sprayed waterproof layer on the water-facing side. The externally sprayed waterproof layer is preferably made of flexible materials such as polymer cement, polyurethane, and acrylic. There is a decorative layer on the outside of the externally sprayed waterproof layer. The decorative layer is divided into two parts with the energy-dissipating damping component as the boundary.
[0010] The beneficial effects of this invention are as follows: 1. The sliding connection device can slide laterally within the frame plane under seismic action; the waterproof layer and filling material layer of the damping component have low strength and will fail preferentially under seismic action; the finishing layer is divided into two parts with the energy-dissipating damping component as the boundary. These structural features provide space for the deformation of the composite infill wall panel and the energy-dissipating damping component, without affecting the energy dissipation and vibration reduction effect of the composite infill wall panel and the energy-dissipating damping component under seismic action. 2. The sliding connection device is easy to install and disassemble, and provides convenience for the inspection, maintenance and replacement of the energy-dissipating damping component. 3. This sealing structure not only extends the service life of the energy-dissipating damping component, but also improves the architectural function of the prefabricated vibration-damping composite infill wall: it eliminates the gap at the energy-dissipating damping component, connects the upper and lower composite infill wall panels on the same plane, facilitates the construction of the outer finishing layer of the composite infill wall panel; the waterproof layer and filling material layer of the damping component give the energy-dissipating damping component part fireproof, corrosion-resistant, waterproof, heat-insulating and sound-insulating functions.

Detailed Implementation Example 1
[0019] like Figure 1 As shown, the composite infill wall panel 4 of the prefabricated vibration-damping composite infill wall with sealable energy-dissipating damping components is installed within the structural frame and connected to the structural frame via embedded connecting parts. Lightweight infill wall panels 3 are installed on both sides of the composite infill wall panel 4 within the structural frame. The structural frame includes frame columns 2 and frame beams 1. The composite infill wall panel 4 includes an upper composite infill wall panel 4a and a lower composite infill wall panel 4b. An energy-dissipating damping component 13 is connected between the upper composite infill wall panel 4a and the lower composite infill wall panel 4b via embedded connecting parts. The energy-dissipating damping component 13 is positioned between the upper composite infill wall panel 4a and the lower composite infill wall panel 4b, and the thickness of the energy-dissipating damping component 13 is less than the thickness of the composite infill wall panel 4. A sliding connecting device 6 is installed on one side of the outer side of the energy-dissipating damping component 13. Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the sliding connection device 6 includes a cover plate 7, a sliding groove 8, and a sliding rail 9. The sliding groove 8 and the sliding rail 9 are located inside the cover plate 7. The sliding rail 9 is nested within the sliding groove 8 inside the cover plate 7 and is fixedly connected to the embedded steel plate or embedded reinforcing bar at the lower part of the upper composite infill wall panel 4a. A sliding gap 19 is left between the end of the sliding rail 9, the end of the sliding groove 8, and the cover plate 7. The sliding gap 19 is not less than the width of the gap between the composite infill wall panel 4 and the frame column 2. The cover plate 7 can slide laterally on the sliding rail 9 via the sliding groove 8, and can also rotate circumferentially around the axis of the sliding rail 9.
[0020] A latch 10 is installed at the lower part of the cover plate 7. The latch 10 is equipped with a switch to control the extension and retraction of the latch 11. A baffle strip 12 is provided between the latch 11 and the cover plate 7. The baffle strip 12 is fixedly connected to the upper end of the lower composite infill wall panel 4b by a pre-embedded steel plate or pre-embedded steel bar. When the cover plate is closed, the control switch causes the latch 11 to extend out of the latch 10 to prevent the cover plate 7 from rotating; when the cover plate 7 is open, the control switch causes the latch 11 to retract into the latch 10.
[0021] The energy-dissipating damping component has a waterproof layer 14 on the water-facing side 18. The waterproof layer 14 can be composed of lightweight thermal insulation mortar and its double-sided waterproof coating, or a composite waterproof mortar. The double-sided waterproof coating of the lightweight thermal insulation mortar uses epoxy or modified epoxy coatings as sealing materials, or cement-based or silicone (siloxane) penetrating materials; the composite waterproof mortar uses cement-based composite waterproof mortar, or polymer cement waterproof mortar. These materials also have good corrosion resistance.
[0022] There is a filling material layer 15 between the damping waterproof layer 14 and the sliding connection device 6. The filling material layer 15 is composed of functional filling materials such as heat insulation, sound insulation, and fireproofing, and uses materials such as rock wool, pearl cotton, flame-retardant rubber and plastic sponge, glass wool, or combinations thereof.
[0023] The composite infill wall panel 4 and the energy-dissipating damping component 13 have an externally sprayed waterproof layer 16 on one side of the water-facing surface 18. The externally sprayed waterproof layer 16 should preferably be made of flexible materials such as polymer cement, polyurethane, and acrylic. The outer side of the externally sprayed waterproof layer 16 has a decorative layer 17.
[0024] When installing vibration-damping composite infill walls, follow these steps:
[0025] Step 1: Install composite infill wall panels 4. The installation sequence of composite infill wall panels 4 can be either the upper composite infill wall panel 4a or the lower composite infill wall panel 4b first. After the frame beam 1, frame column 2 and pier 5 are constructed, position and install the first set of composite infill wall panels 4 (upper composite infill wall panel 4a, energy dissipation damping component 13 and lower composite infill wall panel 4b) on the frame beam 1 or pier 5, and then install the second set and the remaining composite infill wall panels 4 in sequence.
[0026] The second step is to apply a filling material layer 15 to the side of the energy-dissipating damping component 13 on the water-facing side of the composite infill wall panel 4. The filling material layer is composed of functional filling materials such as heat insulation, sound insulation, and fireproofing, and uses materials such as rock wool, pearl cotton, flame-retardant rubber and plastic sponge, glass wool, or combinations thereof. Then, apply lightweight heat-insulating mortar along the thickness direction of the composite infill wall panel 4, and then apply the damping component waterproof layer 14 on the lightweight heat-insulating mortar. The waterproof coating should preferably be a closed material such as epoxy or modified epoxy coating, or a cement-based or silicone (siloxane) penetrating material; or apply composite waterproof mortar, using cement-based composite waterproof mortar or polymer cement waterproof mortar.
[0027] The third step is to apply a filling material layer 15 in the interlayer between the energy-dissipating damping component 13 and the sliding connection device 6. The filling material layer 15 is composed of functional filling materials such as heat insulation, sound insulation, and fireproofing, and uses materials such as rock wool, pearl cotton, flame-retardant rubber and plastic sponge, glass wool, or combinations thereof.
[0028] Step 4: Install the sliding connection device 6. On the non-water-facing side of the composite infill wall panel 4 in the thickness direction, fix the baffle strip 12 to the pre-embedded steel plate or pre-embedded reinforcing bar at the upper end of the lower composite infill wall panel 4b by welding. Prefabricate the slide rail 9 into the slide groove 8 inside the cover plate 7 of the sliding connection device, allowing the cover plate 7 to slide laterally on the slide rail 9 and rotate circumferentially around the axis of the slide rail 9. Fix the slide rail 9 to the pre-embedded reinforcing bar or pre-embedded steel plate at the lower end of the upper composite infill wall panel 4a by welding. After the sliding connection device 6 is connected to the upper composite infill wall panel 4a, ensure that the lateral sliding gap 19 is not less than the gap width between the composite infill wall panel 4 and the frame column 2.
[0029] Step 5: After leveling the water-facing side of the composite infill wall panel 4 and energy-dissipating damping component 13, apply an external spray waterproof layer 16. The external spray waterproof layer 16 should preferably be made of flexible materials such as polymer cement, polyurethane, and acrylic.
[0030] Step 6: Apply the finishing layer 17 to the outside of the outer waterproof layer 16. The finishing layer 17 can be applied by hanging, laying, brushing, etc. The finishing layer is divided into upper and lower parts with the energy-dissipating damping part as the boundary, so as to provide space for the lateral deformation of the composite infill wall panel 4 and the energy-dissipating damping part 13.
[0031] The scope of protection under this patent is not limited to the aforementioned composite infill wall panel structure, but also includes other damping structures with cantilever walls and damping components, such as composite infill wall panel structures with wall-type viscous dampers; or composite infill wall panel structures without energy-dissipating damping components in the middle between the upper and lower composite infill wall panels, such as... Figure 7 As shown.
[0032] The sliding connection device 6 or the waterproof layer 14 of the damping component is applied on both sides of the thickness direction of the energy-dissipating damping component 13, or the externally sprayed waterproof layer 16 or the decorative layer 17 is applied on both sides of the thickness direction of the composite infill wall panel 4 and the energy-dissipating damping component 13. Such a structure is also the protected content of this invention.
