Description

Technical Field

[0001] The present invention relates to the structural engineering field of building engineering technology, in particular to a wall panel and beam column toughness connection structure and a wall panel assembly method. Background Art

[0002] With the development of the economy and the continuous advancement of science and technology, establishing seismic fortification systems solely for traditional engineering structures can no longer meet the social functions and economic value carried by the current urban and rural systems. Improving the disaster adaptability and disaster resistance of urban and rural systems, enhancing the seismic resilience of building structures, and systematically and large-scalely improving earthquake safety and resilience in urban construction are important directions for future development. The seismic resilience of a building refers to the ability of a building to maintain and restore its original building functions after being subjected to a set level of earthquake action. Taking the common non-structural components in buildings, such as infill wall panels, as an example, in earthquakes, structural components often remain undamaged or suffer minor damage, but infill wall panels develop cracks and damage, or even collapse, which has a significant impact on the seismic resilience of the structure. Therefore, how to design the connection structure between the building infill wall panels and the main structure to achieve damage control for displacement-sensitive non-structural components such as walls is an issue that needs to be urgently addressed.

[0003] Currently, there are two common methods for connecting infill panels to the main structure: rigid and flexible. A rigid connection involves rigidly connecting the infill panels to the frame beam-column system. This method strengthens the integrity of the infill panels and the frame, ensuring deformation coordination between them. However, the allowable deformation limit of the infill panels is often less than the inter-story drift limit of the frame, causing the infill panels to be damaged before the main structure. Furthermore, the rigid connection between the infill wall and the main structure causes the panels to participate in the structural lateral load to a certain extent, but the extent of this participation (such as stiffness and damping contributions) is difficult to quantify, leading to uncertainty in the seismic response analysis results of the structural system (including the main structure and infill walls). A flexible connection between the infill panels and the main structure involves reserving a sufficiently wide gap between the infill panels and the frame columns. This gap is filled with polystyrene foam or polyurethane foam, allowing the infill panels to be readily engaged in earthquake response. This alleviates the problem of mismatched deformation limits between the main structure and the infill panels, which can affect the structural seismic resilience. However, the current flexible connection structure still cannot improve the constraint stiffness and bearing capacity of the infill wall panels along the out-of-plane direction, which can easily lead to the out-of-plane collapse of the infill wall panels under the action of the inertial force in the vertical plane direction, and cannot meet the current requirements for seismic toughness of building structures.

[0004] In response to the above-mentioned issues, the present invention proposes a resilient connection structure between infill wall panels and beam-column systems. This structure offers the following advantages: First, the novel structure releases the in-plane deformation differential between the infill wall panels and the beam-column system, preventing the infill wall panels from contributing to the structural lateral resistance. Second, the novel connection structure, through the staggered arrangement of L-shaped brackets, effectively improves the out-of-plane restraint stiffness and bearing capacity of the infill wall panels, preventing the wall from tipping over and collapsing under out-of-plane inertial forces. Third, the connection structure is simple, highly standardized, and quick and easy to install. It also eliminates the need for drilling holes in the beam-column components, thus maintaining the bearing capacity of the main structure. Summary of the Invention

[0005] The present invention proposes a tough connection structure between a wall panel and a beam column, which includes an L-shaped bracket;

[0006] Upper gasket;

[0007] Lower gasket;

[0008] The upper gasket and the lower gasket can be connected to the L-shaped pick-up piece through the mounting structure. The L-shaped pick-up piece can pass through the gap between the wall panel and the beam. The L-shaped pick-up piece can slide along the top of the wall panel.

[0009] In a preferred embodiment of the flexible connection structure between the wall panel and the beam column of the present invention: the upper gasket and the lower gasket are installed at the end of the gap between the L-shaped bracket passing through the wall panel and the beam through the installation structure.

[0010] In a preferred embodiment of the flexible connection structure between the wall panel and the beam column of the present invention: the L-shaped bracket, the upper gasket, and the lower gasket are all provided with holes; the mounting structure is a bolt and a nut, and the bolt can pass through the L-shaped bracket, the upper gasket, and the lower gasket at the same time through the hole.

[0011] In a preferred embodiment of the flexible connection structure between the wall panel and the beam column of the present invention, the thickness of the lower gasket is consistent with the thickness of the beam flange.

[0012] In a preferred embodiment of the flexible connection structure between the wall panel and the beam column of the present invention, the upper gasket is in contact with the upper surface of the beam flange of the beam.

[0013] In a preferred embodiment of the flexible connection structure between the wall panel and the beam column of the present invention: the L-shaped bracket is provided with a restraining side, and the restraining side of the L-shaped bracket is used to restrain the wall panel.

[0014] In a preferred embodiment of the flexible connection structure between the wall panel and the beam column of the present invention: the end of the upper gasket is closer to the restraining side of the L-shaped bracket than the lower gasket.

[0015] In a preferred embodiment of the flexible connection structure between the wall panels and beams and columns of the present invention: at least one pair of L-shaped brackets are provided between the wall panels and the beams, and the restraining sides of the two L-shaped brackets in a pair are used to restrain the side surfaces of the wall panels away from each other.

[0016] The present invention also proposes a wall panel assembly method, which uses the above-mentioned wall panel and beam-column flexible connection structure for assembly; including connecting the bottom of the wall panel with the lower floor slab; using an L-shaped bracket to pass through the gap between the wall panel and the beam; and connecting the upper gasket and the lower gasket with the L-shaped bracket.

[0017] In a preferred embodiment of the flexible connection structure between the wall panel and the beam column of the present invention: gaps are reserved between the two sides of the wall panel and the frame columns, and a gap is reserved between the wall panel and the beam.

[0018] The beneficial effects of the present invention are:

[0019] First, the invention does not rigidly connect the frame structure and the infill wall panels, which fully releases the displacement difference between the two. The inter-layer displacement of the frame will not be completely transferred to the infill wall panels. Therefore, the invention ensures that the infill wall panels will not be damaged due to exceeding the displacement limit.

[0020] Second, during earthquakes, the infill panels are not subject to significant seismic forces, preventing damage caused by forces exceeding their acceptable bearing capacity. Because the infill panels remain intact, stress redistribution does not increase the internal forces of the main structure, thus preventing damage to the main structure.

[0021] Third, the invention can effectively restrain the out-of-plane deformation of the filling wallboard, thereby improving the ability of the filling wallboard to resist out-of-plane inertial forces.

[0022] Fourthly, the structure of the invention has the characteristics of easy installation and can be conveniently installed and used during construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0030] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0031] Reference Figure 1 This embodiment provides a flexible connection structure between a wall panel and a beam column, including an L-shaped pick 100; an upper gasket 200; and a lower gasket 300. The upper gasket 200 and the lower gasket 300 can be connected to the L-shaped pick 100 through an installation structure 400. The L-shaped pick 100 can pass through the gap between the wall panel A and the beam B, and the L-shaped pick 100 can slide along the top of the wall panel A.

[0032] In this embodiment, the L-shaped bracket 100 can pass through the gap between the wall panel A and the beam B. The two parts of the L-shaped bracket 100 are the first end 102 and the second end 103. When in use, the first end 102 can fit the wall panel A, and the second end 103 can extend through the gap between the wall panel A and the beam B. The lengths of the upper gasket 200 and the lower gasket 300 are inconsistent. The length of the upper gasket 200 is greater than the length of the lower gasket 300. When the upper gasket 200 and the lower gasket 300 are installed on the L-shaped bracket 100, the upper gasket 200, the lower gasket 300, and the L-shaped bracket 100 can form a structure similar to a hook mouth. The entire connection structure constrains the wall panel A through the first end 102 of the L-shaped bracket 100 and connects the beam B through the hook mouth structure.

[0033] There is a gap between the wall panel A and the beam B. When an earthquake occurs, the L-shaped bracket 100 can slide along the gap, that is, slide along the top of the wall panel A.

[0034] The upper gasket 200 and the lower gasket 300 are installed on the end of the L-shaped member 100 passing through the gap between the wall panel A and the beam B through the installation structure 400. Specifically, holes are provided on the L-shaped member 100, the upper gasket 200, and the lower gasket 300; the installation structure 400 is a bolt 401 and a nut 402, and the bolt 401 can pass through the L-shaped member 100, the upper gasket 200, and the lower gasket 300 at the same time through the hole. In this embodiment, the holes provided on the L-shaped member 100, the upper gasket 200, and the lower gasket 300 are all through holes. When connecting, the bolt 401 passes through these three holes at the same time, and then is connected to the bolt 401 through the nut 402, so that the upper gasket 200, the lower gasket 300, and the L-shaped member 100 can be connected together.

[0035] The L-shaped bracket 100 is provided with a restraining side 101, and the restraining side 101 of the L-shaped bracket 100 is used to restrain the wall panel A. The thickness of the lower gasket 300 is consistent with the thickness of the beam flange B1 of the beam B, and the upper gasket 200 is in contact with the upper surface of the beam flange B1 of the beam B. The end of the upper gasket 200 is closer to the restraining side 101 of the L-shaped bracket 100 relative to the lower gasket 300. The thickness of the lower gasket 300 is consistent with the thickness of the beam flange B1. In this way, the lower surface of the lower gasket 300 above the upper gasket 200 can be in contact with the upper surface of the beam flange B1. The end of the upper gasket 200 is closer to the restraining side 101 of the L-shaped bracket 100 relative to the lower gasket 300, so that the end of the upper gasket 200 can extend above the beam flange B1.

[0036] At least one pair of L-shaped picks 100 is provided between the wall panel A and the beam B. The restraining sides 101 of the two L-shaped picks 100 in a pair are used to restrain the sides of the wall panel A away from each other. However, in general, more L-shaped picks 100 will be used. For example, as shown in the figure, 12 connection structures are used between the wall panel A and the beam B. The gaps between these connection structures are preferably equidistant, and these connection structures are staggered. That is, the wall panel A has an A surface and a B surface. The restraining side 101 of the first L-shaped pick 100 contacts the A surface, the restraining side 101 of the second L-shaped pick 100 contacts the B surface, and the restraining side 101 of the third L-shaped pick 100 contacts the A surface again, and so on.

[0037] Ensure that there are an equal number of L-shaped brackets 100 on both sides of the wall panel A to strengthen the out-of-plane stiffness and bearing capacity of the wall panel A. Under the action of an earthquake, when the wall panel A is subjected to the out-of-plane inertial force, the L-shaped bracket 100 will provide a force in the opposite direction at the top of the filling wall panel A. At the same time, the L-shaped bracket 100 will transfer the force to the lower gasket 300 on the opposite side through the bolt 401, and transfer it to the beam flange B1 of the beam B, thereby ensuring that the filling wall panel A will not suffer out-of-plane damage. When using this connection structure, bolts 401 or welding should not be used to connect the connection structure and beam B to ensure that the bearing capacity of beam B is not weakened.

[0038] In one embodiment provided in the present application, a wall panel assembly method is also proposed, which uses the above-mentioned flexible connection structure between wall panels and beams and columns for assembly; including: connecting the bottom of wall panel A to the lower floor slab; reserving gaps between the two sides of wall panel A and the frame columns, and reserving gaps between wall panel A and beam B, and using an L-shaped bracket 100 to pass through the gap between wall panel A and beam B; connecting the upper gasket 200 and the lower gasket 300 to the L-shaped bracket 100, so in this assembly method, the bottom end of wall panel A is fixedly connected to the lower floor slab of the entire building, and the top of wall panel A is connected to beam B through the L-shaped bracket 100.

[0039] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
