Description

Technical Field

[0001] The utility model relates to an assembled shock-absorbing composite filling wall, in particular to an assembled shock-absorbing composite filling wall with an energy-consuming damping component maintenance device. Background Art

[0002] In order to cooperate with the building function, the shock-absorbing device often sets the energy-absorbing damping parts between the upper and lower cantilever walls in the frame, such as wall-type viscous dampers and rod-type viscous dampers (wall-type structures); another example is a prefabricated shock-absorbing lightweight composite infill wall panel structure disclosed in Chinese patent CN218292374U, which includes upper and lower composite infill wall panels arranged in the frame and energy-absorbing damping parts between the composite infill wall panels. Under the action of an earthquake, the upper and lower composite infill wall panels and the energy-absorbing damping parts deform in the plane of the frame to absorb energy and dissipate shock, so as to reduce the interaction between the frame structure and the composite infill wall panels.

[0003] This cantilever wall panel plus energy-absorbing damping component structure integrates the partition function of the building wall with the energy-absorbing and shock-absorbing function of the structure, which eliminates the impact of the shock-absorbing device on the building function to a certain extent. However, there are still the following shortcomings: First, the energy-absorbing damping component is exposed to the external environment, which affects the appearance and increases the risk of damage and failure of the energy-absorbing damping component (such as oxidation corrosion, etc.); or the energy-absorbing damping component is buried in the wall, which makes it difficult to inspect, maintain and replace it. Second, the gaps in the energy-absorbing damping component make it difficult to apply the outer surface of the structure, and at the same time, the building functions of the structure such as waterproofing, heat preservation, fire prevention and anti-corrosion have not been perfected, which makes the structure unable to be used in the building's outer wall, bathroom, kitchen, basement and other locations. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an assembled shock-absorbing composite filling wall which has an energy-dissipating damping element that is sealable, fire-proof, corrosion-resistant, waterproof, heat-insulating and sound-insulating.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: the assembled shock-absorbing composite infill wall with an energy-absorbing damping member maintenance device includes a structural frame, a composite infill wall panel, a lightweight infill wall panel, and an energy-absorbing damping member. The composite infill wall panel and the lightweight infill wall panel are installed in the structural frame. The composite infill wall panel is connected to the structural frame through connecting embedded parts. The lightweight infill wall panel is on both sides of the composite infill wall panel. The structural frame includes a frame column and a frame beam. The frame beam includes an upper frame beam and a lower frame beam. The composite infill wall panel includes an upper composite infill wall panel and a lower composite infill wall panel. The energy-absorbing damping member is connected between the upper composite infill wall panel and the lower composite infill wall panel. The thickness of the energy-absorbing damping member is less than the thickness of the composite infill wall panel. A slidable connection device is installed on one side of the outer side of the energy-absorbing damping member. The slidable connection device includes a cover plate, a slide groove, and a slide rail. The slide groove and the slide rail are on the inner side of the cover plate. The slide rail is embedded in the slide groove on the inner side of the cover plate and is fixedly connected to the embedded steel plate or embedded steel bar at the lower part 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 gap width between the composite filling wall panel and the frame column. The cover plate can slide horizontally on the slide rail through the slide groove and can also rotate circumferentially around the axis of the slide rail.

[0006] In the above technical solution, a lock is installed at the lower part of the cover plate, and a switch is provided on the lock to control the extension and retraction of the lock tongue. A baffle strip is provided between the lock tongue and the cover plate, and the baffle strip is fixedly connected to the upper end of the lower composite filling wall panel through a pre-embedded steel plate or pre-embedded steel bar. When the cover plate is closed, the control switch causes the lock tongue to extend out of the lock to prevent the cover plate from rotating; when the cover plate is opened, the control switch causes the lock tongue to retract into the lock.

[0007] In the above technical solution, the energy dissipation damping member is provided with a damping member waterproof layer on the water-facing side, and the damping member waterproof layer can be composed of a 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 adopts epoxy or modified epoxy coating-type sealing materials, or cement-based, silicone (siloxane)-type permeable materials; the composite waterproof mortar adopts cement-based composite waterproof mortar, or polymer cement waterproof mortar, and this type of material also has good anti-corrosion performance.

[0008] In the above technical solution, there is a filling material layer between the waterproof layer of the damping element and the energy-absorbing damping element, and there is a filling material layer between the energy-absorbing damping element and the slidable connecting device. The filling material layer is composed of thermal insulation, sound insulation, and fire-proof functional filling materials, and is made of rock wool, pearl cotton, flame-retardant rubber and plastic sponge, glass wool and other materials, or a combination thereof, or is left blank.

[0009] In the above technical solution, the water-facing side of the composite filling wall panel and the energy-absorbing damping component is provided with an external sprayed waterproof layer as a whole. The external sprayed waterproof layer is preferably made of flexible materials such as polymer cement, polyurethane, acrylic acid, etc. There is a finishing layer on the outside of the external sprayed waterproof layer, and the finishing layer is divided into two parts upper and lower with the energy-absorbing damping component as the boundary.

[0010] The utility model has the following beneficial effects: 1. The sliding connection device can slide laterally in the plane of the frame under the action of an earthquake; the waterproof layer and the filling material layer of the damping element have low strength and are first destroyed and fail under the action of an earthquake; the finishing layer is divided into two parts with the energy-absorbing damping element as the boundary. These structural features can provide space for the deformation of the composite filling wall panels and the energy-absorbing damping elements, and do not affect the energy-absorbing and shock-absorbing effect of the composite filling wall panels and the energy-absorbing damping elements under the action of an earthquake. 2. The sliding connection device is easy to install and disassemble, and provides convenience for the inspection, maintenance and replacement of the energy-absorbing damping elements. 3. The sealing structure not only prolongs the service life of the energy-absorbing damping elements, but also improves the architectural function of the assembled shock-absorbing composite filling wall: the gap in the energy-absorbing damping element is eliminated, the upper and lower composite filling wall panels are connected to the same plane, and the application of the finishing layer on the outer side of the composite filling wall panel is facilitated; the waterproof layer and the filling material layer of the damping element enable the energy-absorbing damping element to have fireproof, anti-corrosion, waterproof, heat-insulating and sound-insulating functions.

The slide groove 8 and the slide rail 9 are on the inner side of the cover plate 7. The slide rail 9 is embedded in the slide groove 8 on the inner side of the cover plate 7 and is fixedly connected to the embedded steel plate or embedded steel bar at the lower part of the upper composite filling wall panel 4a. A sliding gap 19 is left between the end of the slide rail 9 and the end of the slide groove 8 and the cover plate 7.

Such materials also have good anti-corrosion properties.

The filling material layer 15 is composed of functional filling materials such as thermal insulation, sound insulation, and fire prevention, and is made of rock wool, pearl cotton, flame retardant rubber and plastic sponge, glass wool, or a combination thereof.

[0024] The composite filling wallboard 4 and the water-facing surface 18 of the energy-absorbing damping member 13 are integrally provided with an external spray-coated waterproof layer 16 . The external spray-coated waterproof layer 16 is preferably made of flexible materials such as polymer cement, polyurethane, acrylic acid, etc., and a finishing layer 17 is provided on the outside of the external spray-coated waterproof layer 16 .

[0025] When installing a shock-absorbing composite infill wall, follow these steps:

[0026] The first step is to install the composite infill wall panels 4. The installation order of the composite infill wall panels 4 can be to install any one of the upper composite infill wall panels 4a and the lower composite infill wall panels 4b first. After the construction of the frame beam 1, the frame column 2 and the pier 5 is completed, the first set of composite infill wall panels 4 (upper composite infill wall panels 4a, energy dissipation damping members 13 and lower composite infill wall panels 4b) are positioned and installed on the frame beam 1 or the pier 5, and then the second set and the remaining composite infill wall panels 4 are installed in sequence.

[0027] In the second step, a filling material layer 15 is first applied on the side of the energy-absorbing damping member 13 on the water-facing surface 18 of the composite filling wall panel 4. The filling material layer is composed of functional filling materials such as thermal insulation, sound insulation, and fire prevention, and adopts rock wool, pearl cotton, flame-retardant rubber and plastic sponge, glass wool and other materials, or a combination thereof; then a lightweight thermal insulation mortar is applied along the thickness direction of the composite filling wall panel 4, and then a damping member waterproof layer 14 is applied on the lightweight thermal insulation mortar. The waterproof coating should preferably adopt epoxy or modified epoxy coating type closed materials, or cement-based, silicone (siloxane) type penetrating materials; or a composite waterproof mortar is applied, using cement-based composite waterproof mortar, or polymer cement waterproof mortar.

[0029] Step 4: Install the slidable connection device 6. On the non-water-facing side of the thickness direction of the composite infill wall panel 4, fix the baffle strip 12 to the embedded steel plate or embedded steel bar at the upper end of the lower composite infill wall panel 4b by welding; nest the slide rail 9 in the slide groove 8 on the inner side of the cover plate 7 of the slidable connection device by prefabrication, so that the cover plate 7 can slide horizontally on the slide rail 9 and rotate circumferentially around the axis of the slide rail 9, and fix the slide rail 9 to the embedded steel bar or embedded steel plate at the lower end of the upper composite infill wall panel 4a by welding. After the slidable connection device 6 is connected to the upper composite infill wall panel 4a, it should be ensured that the lateral sliding gap 19 is not less than the gap width between the composite infill wall 4 and the frame column 2.

[0030] Step 5: After the water-facing side of the composite filling wallboard 4 and the energy dissipation damping member 13 is leveled, an external spray waterproof layer 16 is applied as a whole. The external spray waterproof layer 16 is preferably made of flexible materials such as polymer cement, polyurethane, acrylic acid, etc.
