PREFABRICATED INFILLED PANEL-FRAME STRUCTURE CAPABLE OF ACCOMMODATING SEISMIC LOADING AND SEISMIC ENERGY DISSIPATION, AND CONSTRUCTION METHOD

Abstract

The present invention relates to a prefabricated infilled panel-frame structure capable of accommodating seismic-loading and seismic energy dissipation, and a construction method thereof, including a frame body, a prefabricated infilled panel group, a panel connector, and a disc spring assembly. During an earthquake, the present invention slides to dissipate energy only after the maximum starting sliding force is exceeded, thus providing the structure with a relatively high lateral stiffness prior to sliding. After an earthquake, the disc spring assembly of the present invention may provide a certain restoring force due to being compressed so as to reduce the residual displacement. Further, the present invention achieves the bidirectional deformation cooperation of the prefabricated infilled panel under earthquakes, so that the infilled panel may still achieve the function of seismic energy dissipation under the coupling action of in-plane and out-of-plane loads.

[0065] For ease of description, the words upper, lower, left and right in the present invention, if they appear in the upper, lower, left and right directions of the drawings themselves, are not meant to be limiting in structure, but merely to facilitate description of the invention and to simplify the description. They do not indicate or imply that the apparatus or elements referred to must have a particular orientation, are constructed and operated in a particular orientation, and are therefore not to be construed as limiting the invention.

Example 1

[0066] As shown in FIGS. 6-17, the present example provides a prefabricated infilled panel-frame structure, including a frame body in which a prefabricated infilled panel group is installed. The frame body includes a frame top beam 1, a frame bottom beam 2, a frame left column 3, and a frame right column 4. The frame top beam 1 is parallel to the frame bottom beam 2. The frame left column 3 is parallel to the frame right column 4. The left and right ends of the frame top beam 1 and the frame bottom beam 2 are reliably connected to the frame left column 3 and the frame right column 4 respectively.

[0067] The prefabricated infilled panel group includes a plurality of vertical sub-panels, which are arranged in sequence from left to right, and include a left vertical panel 5 and a right vertical panel 7 respectively located at the left and right outer sides, and a plurality of middle vertical panels 6 located between the left vertical panel 5 and the right vertical panel 7. The side wall of the vertical sub-panels is provided with a splicing ridge 14 or a splicing groove 13. An integral unit of the prefabricated infilled panel group is formed between adjacent vertical sub-panels by means of a panel splicing adhesive and a splicing connection between the splicing groove 13 and the splicing ridge 14. Each vertical sub-panel includes a main board, an damping layer, and a secondary board. Taking the left vertical panel 5 as an example, the left vertical panel 5 includes a left vertical panel main board 51 located above, a left vertical panel secondary board 52 located below, and an damping layer 8 located between the left vertical panel main board 51 and the left vertical panel secondary board 52. The earthquake-reduction layer 8 is adhered between a semicircular groove 15 at the bottom of the left vertical panel main board 51 and a semicircular ridge 16 at the top of the left vertical panel secondary board 52. The semicircular groove 15 and the semicircular ridge 16 may be inserted and fitted with each other. The left vertical panel main board 51 may rotate to some extent along the semicircular ridge 16 at the top of the left vertical panel secondary board 52. The left vertical panel 5 and the frame bottom beam 2 are connected via cast-in-place fine stone concrete 11. The left vertical panel 5 and the frame top beam 1 are connected via a U-shaped connector 12. The U-shaped connector 12 and the frame top beam 1 are connected via nailing. The U-shaped connector 12 and the left vertical panel 5 only contact at front and rear surfaces. The structures of the plurality of middle vertical panels 6, the right vertical panel 7 and the left vertical panel 5 are basically the same, and will not be repeated.

[0068] Among them, the bottom of each secondary board is further provided with a ridge. When the cast-in-place fine stone concrete 11 is solidified and hardened, a shear key will be formed with the ridge at the bottom of the secondary board, and the shear key at the bottom of the panel and the U-shaped connector 12 at the top may effectively limit the panel from having an out-of-plane displacement so as to improve the out-of-plane bearing performance.

[0069] The gaps between the left upper portion of the left vertical panel 5 and the frame body 2, and the right upper portion of the right vertical panel 7 and the frame body 2 are connected via a panel group fastener 9. The panel group fastener 9 is formed by casting fine stone concrete using a formwork, and is L-shaped. A disc spring assembly 10 is mounted between the left lower portion of the main board 51 of the left vertical panel in the left vertical panel 5 and the left column 3 of the frame, and between the right lower portion of the main board 71 in the right vertical panel 7 and the right column 4 of the frame. The disc spring assembly 10 includes a disc spring box 101, a disc spring 102, and a disc spring backing plate 103. The disc spring box 101 is connected to the frame body via nailing. The disc spring 102 is in a pre-pressed state. The disc spring backing plate 103 is only in hard contact with the surface of the earthquake-reduction panel group.

[0070] Under the action of the horizontal earthquake, the frame top beam 1 is displaced horizontally and driven by the panel group fastener 9 to cause the driven sliding tendency of the prefabricated infilled panel group. The disc spring 102 is compressed and deformed when the prefabricated infilled panel group overcomes the starting sliding force. The main board and the secondary board of the prefabricated infilled panel group have sliding hysteresis and deformation along the damping layer 8 to dissipate the seismic input energy. After the horizontal earthquake, the disc spring 102 is in the compressed state due to the residual displacement of the prefabricated infilled panel group after the earthquake. Thus, the disc spring 102 may provide a certain restoring force to reduce the residual displacement after the earthquake and reduce the time cost and economic cost of quickly restoring to the pre-earthquake state. In addition, when the structure is subjected to the out-of-plane load, the semicircular groove 15 at the bottom of the main board and the semicircular ridge 16 at the top of the secondary board of the prefabricated infilled panel will slide uniformly (surface to surface contact) along the damping layer 8 between the both and generate a certain amount of out-of-plane shear energy dissipation. When the structure continues to be subjected to the in-plane load, because the semicircular grooves 15 and the semi-circular ridges 16 still maintain uniform surface contact, stable sliding hysteretic energy dissipation may still occur in the surface, thus ensuring the cooperated deformation and energy dissipation of the wall under in-plane and out-of-plane load coupling.

Example 2

[0071] It is substantially the same as in Example 1, except that

[0072] The damping layer 8 is made of a material having function of energy dissipation, such as SBS coiled materials or low-strength mortar.

[0073] The frame body is a reinforced concrete frame or a steel frame.

Example 3

[0074] This example discloses a construction method for a prefabricated infilled panel-frame structure provided in the previous examples. As shown in FIGS. 18-20, before the assembly of the prefabricated infilled panel group, the construction of the frame body should be completed first. The impurities of the frame top beam and the frame bottom beam should be cleaned. The base surface leveling treatment should be performed. The panel installation location line is then popped out at a panel installation location according to the construction drawing to indicate the panel installation location.

[0075] The method for constructing the prefabricated infilled panel-frame structure includes the steps of:

Step 1:

[0076] According to a pre-marked infilled panel installation position, after the left vertical panel 5 is positioned, a U-shaped connector 12 is installed at the top thereof and a wood wedge is inserted at the bottom thereof. The installation schematic diagram is shown in FIG. 18. During the installing, the verticality of wall surface is adjusted by using a ruler, so that the lower edge of panel coincides with the installation position line of panel, so as to ensure that the verticality and flatness of panel meet the requirements of standards and specifications.

Step 2:

[0077] The step 1 process is repeated, with several middle vertical panels 6 and right vertical panels 7 successively installed and spliced. During the splicing, it firstly paints a panel splicing adhesive in the splicing groove 13 between adjacent vertical panels, and then splices the splicing groove 13 and the splicing ridge 14 so as to form an integral unit of prefabricated infilled panel group.

Step 3:

[0078] The fine stone concrete was poured into the gap between the bottom of the prefabricated infilled panel group and the top of the frame bottom beam 2 after the splicing of the prefabricated infilled panel group is completed. During the pouring, it should ensure that the bottom of the cast-in-place fine stone concrete 11 completely fills the gap, and enabling the fine stone concrete to pour flush with the top of the secondary boards 51 and 71 at the gap between the prefabricated filled panel group and the frame left column 3 or right column 4. The schematic diagram of the pouring height of the gap is shown in FIG. 16. After the cast-in-place fine stone concrete 11 at the bottom is hardened, the bottom wood wedge is withdrawn and the fine stone concrete is filled at the hole left by the wood wedge. Furthermore, a panel group fastener 9 is formed by casting in a formwork the fine stone concrete at the left upper portion and the right upper portion of the prefabricated filled panel group. Further, a disc spring assembly 10 is installed at the bottom of one sides of the left vertical panel 5 and the right vertical panel 6 near to the frame body, respectively. The detailed installation position of the disc spring assembly 10 is schematically shown in FIGS. 6 and 16.

Step 4:

[0079] According to the requirements of moisture resistance, sound insulation, and thermal insulation, the other gaps between the prefabricated infilled panel and the frame body are filled and caulking with suitable flexible connecting materials.

[0080] Although the particular embodiments of the present invention have been described above with reference to the accompanying drawings, it is not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications and variations made in the present invention without involving any inventive effort are still within the protection scope of the present invention.
