Example 1

As shown inFIGS.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 beam1, a frame bottom beam2, a frame left column3, and a frame right column4. The frame top beam1is parallel to the frame bottom beam2. The frame left column3is parallel to the frame right column4. The left and right ends of the frame top beam1and the frame bottom beam2are reliably connected to the frame left column3and the frame right column4respectively.

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 panel5and a right vertical panel7respectively located at the left and right outer sides, and a plurality of middle vertical panels6located between the left vertical panel5and the right vertical panel7. The side wall of the vertical sub-panels is provided with a splicing ridge14or a splicing groove13. 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 groove13and the splicing ridge14. Each vertical sub-panel includes a main board, an damping layer, and a secondary board. Taking the left vertical panel5as an example, the left vertical panel5includes a left vertical panel main board51located above, a left vertical panel secondary board52located below, and an damping layer8located between the left vertical panel main board51and the left vertical panel secondary board52. The earthquake-reduction layer8is adhered between a semicircular groove15at the bottom of the left vertical panel main board51and a semicircular ridge16at the top of the left vertical panel secondary board52. The semicircular groove15and the semicircular ridge16may be inserted and fitted with each other. The left vertical panel main board51may rotate to some extent along the semicircular ridge16at the top of the left vertical panel secondary board52. The left vertical panel5and the frame bottom beam2are connected via cast-in-place fine stone concrete11. The left vertical panel5and the frame top beam1are connected via a U-shaped connector12. The U-shaped connector12and the frame top beam1are connected via nailing. The U-shaped connector12and the left vertical panel5only contact at front and rear surfaces. The structures of the plurality of middle vertical panels6, the right vertical panel7and the left vertical panel5are basically the same, and will not be repeated.

Among them, the bottom of each secondary board is further provided with a ridge. When the cast-in-place fine stone concrete11is 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 connector12at the top may effectively limit the panel from having an out-of-plane displacement so as to improve the out-of-plane bearing performance.

The gaps between the left upper portion of the left vertical panel5and the frame body2, and the right upper portion of the right vertical panel7and the frame body2are connected via a panel group fastener9. The panel group fastener9is formed by casting fine stone concrete using a formwork, and is L-shaped. A disc spring assembly10is mounted between the left lower portion of the main board51of the left vertical panel in the left vertical panel5and the left column3of the frame, and between the right lower portion of the main board71in the right vertical panel7and the right column4of the frame. The disc spring assembly10includes a disc spring box101, a disc spring102, and a disc spring backing plate103. The disc spring box101is connected to the frame body via nailing. The disc spring102is in a pre-pressed state. The disc spring backing plate103is only in hard contact with the surface of the earthquake-reduction panel group.

Under the action of the horizontal earthquake, the frame top beam1is displaced horizontally and driven by the panel group fastener9to cause the driven sliding tendency of the prefabricated infilled panel group. The disc spring102is 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 layer8to dissipate the seismic input energy. After the horizontal earthquake, the disc spring102is in the compressed state due to the residual displacement of the prefabricated infilled panel group after the earthquake. Thus, the disc spring102may 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 groove15at the bottom of the main board and the semicircular ridge16at the top of the secondary board of the prefabricated infilled panel will slide uniformly (surface to surface contact) along the damping layer8between 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 grooves15and the semi-circular ridges16still 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

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

The damping layer8is made of a material having function of energy dissipation, such as SBS coiled materials or low-strength mortar.

The frame body is a reinforced concrete frame or a steel frame.

Example 3

This example discloses a construction method for a prefabricated infilled panel-frame structure provided in the previous examples. As shown inFIGS.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.

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

Step 1:

According to a pre-marked infilled panel installation position, after the left vertical panel5is positioned, a U-shaped connector12is installed at the top thereof and a wood wedge is inserted at the bottom thereof. The installation schematic diagram is shown inFIG.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:

The step 1 process is repeated, with several middle vertical panels6and right vertical panels7successively installed and spliced. During the splicing, it firstly paints a panel splicing adhesive in the splicing groove13between adjacent vertical panels, and then splices the splicing groove13and the splicing ridge14so as to form an integral unit of prefabricated infilled panel group.

Step 3:

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 beam2after 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 concrete11completely fills the gap, and enabling the fine stone concrete to pour flush with the top of the secondary boards51and71at the gap between the prefabricated filled panel group and the frame left column3or right column4. The schematic diagram of the pouring height of the gap is shown inFIG.16. After the cast-in-place fine stone concrete11at 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 fastener9is 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 assembly10is installed at the bottom of one sides of the left vertical panel5and the right vertical panel6near to the frame body, respectively. The detailed installation position of the disc spring assembly10is schematically shown inFIGS.6and16.

Step 4:

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.

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.
