In this connection method, both sides of the lightweight wallboard infill wall are provided with side frames. The upper part of the side frame is horizontally slidably connected to a transverse structural member through a first sliding connecting member, and the lower part of the side frame is fixedly connected to the transverse structural member through a fixed connecting member. A flexible filling component is provided between the side frame and the vertical structural member. The connecting components include a side frame, a cross beam, a first sliding connecting member, a fixed connecting member, and a flexible filling component. The beneficial effects of the present invention are as follows: When the structural main body undergoes lateral deformation under the action of an earthquake, the lightweight wallboard infill wall can still avoid in-plane collision with the structural main body through the first sliding connecting member, and the influence of the lightweight wallboard infill wall on the lateral stiffness of the structural main body can be ignored; the lightweight wallboard infill wall is fixed to the upper and lower structures out of plane and only acts as a load on the supporting structure below it, so that the force of the structure is clear and the force transmission route is clear, ensuring the reliability of the structure.

Description

Technical Field

[0001] The present invention belongs to the technical field of seismic resistance of building structures, and particularly relates to a method for slidably connecting a lightweight wall panel infill wall with a structural main body and a connecting component thereof. Background Art

[0002] Previous earthquake disasters have shown that the lightweight wall panel infill wall, which is rigidly connected to the reinforced concrete structural main body and regarded as a non-structural member, actually participates in the distribution of seismic shear force of the structure. At the same time, the lightweight wall panel infill wall itself has problems such as uncontrollable stiffness, poor ductility, and low energy dissipation capacity, resulting in the lightweight wall panel infill wall structural main body being prone to soft-story failure or torsional failure under earthquake action, thereby causing serious damage or even collapse of the structure.

[0003] Adopting flexible connection basically weakens the interaction between the lightweight wall panel infill wall and the structural main body, although it conforms to the calculation assumption of regarding the lightweight wall panel infill wall as a non-structural member in the current design code. However, due to the lack of effective connection between the current lightweight wall panel infill wall and the structural main body, there is a problem of easy collapse due to out-of-plane instability during an earthquake. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for slidably connecting a lightweight wall panel infill wall with a structural main body and a connecting component thereof, which can slide and deform in the plane and is restricted by the structural main body out of the plane, solving the problems of connection stability and reliability of the existing lightweight wall panel infill wall.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A method for slidably connecting a lightweight wall panel infill wall with a structural main body, wherein two side frames are provided on both sides of the lightweight wall panel infill wall, a cross beam is provided at the top of the masonry infill wall, the cross beam is connected to the side frames, the upper part of the side frames is horizontally slidably connected to a horizontal structural member through a first sliding connecting member, the lower part of the side frames is fixedly connected to the horizontal structural member through a fixed connecting member, and a flexible filling component is provided between the side frames and a vertical structural member.

[0007] Further, the side frames are two angle steels that wrap the front and rear end corners of the lightweight wall panel infill wall.

[0008] Further, the first sliding connecting member is an L-shaped angle steel fixing member, a bolt passes through an oblong hole at one end of the first sliding connecting member to be connected to the horizontal structural member, and the bolt passes through a circular hole at the other end of the first sliding connecting member to be connected to the side frame.

[0009] Further, the fixed connecting member is an L-shaped angle steel fixing member, and bolts respectively pass through circular holes at both ends of the fixed connecting member to be connected to the horizontal structural member and the side frame.

[0010] Further, the horizontal beam is horizontally and slidably connected to the transverse structural member through a second sliding connector.

[0011] Further, the horizontal beam is composed of two angle steels that wrap the front and rear end corners of the lightweight wallboard infill wall.

[0012] Further, the second sliding connector is plate-shaped, and bolts pass through the oblong holes on the second sliding connector and the horizontal beam respectively to be connected to the transverse structural member.

[0013] Further, the flexible filling component is a cold-formed thin-walled flexible filling component with heat preservation, waterproof, fireproof and sound insulation functions.

[0014] Further, the flexible filling component includes a housing, heat preservation and fireproof materials are arranged inside the housing, and caulking materials are arranged in the caulking grooves on the housing opposite to the vertical structural members.

[0015] Further, the transverse structural member is a structural plate or a structural beam, and the vertical structural member is a structural shear wall or a structural column.

[0016] A connecting component of the above-mentioned slidable connection method between the lightweight wallboard infill wall and the structural main body includes a frame and a flexible filling component. The frames are arranged in two groups symmetrically. The upper part of the frame is fixedly connected to the first sliding connector, and a sliding connection part is arranged on the first sliding connector. The lower part of the frame is fixedly connected to the fixed connector, and a fixed connection part is arranged on the fixed connector.

[0017] Functions achieved by the present invention: The lightweight wallboard infill wall can be slidably connected to the structural main body, enabling the lightweight wallboard infill wall to slide in the in-plane direction and restricting its out-of-plane displacement. The main component of the upper first sliding connector is an L-shaped angle steel fixing piece. An oblong hole is opened on one wing of the angle steel fixing piece, that is, the flange connected to the top transverse structural member plate, so that the lightweight wallboard infill wall can slide relative to the structural main body in the plane. A round hole is opened on the other wing of the angle steel fixing piece, that is, the flange connected to the angle steel frame through bolts.

[0018] Advantages of the present invention: When the structural main body undergoes lateral deformation under earthquake action, the lightweight wallboard infill wall is ensured not to collide with the structural main body in the plane through the first sliding connector, and the influence of the lightweight wallboard infill wall on the lateral displacement stiffness of the structural main body can be ignored. At the same time, the lightweight wallboard infill wall is fixed to the upper and lower frame transverse structural members or floors out of the plane and only acts as a load applied to the lower supporting transverse structural member or plate, so that the structure is clearly stressed and the force transmission route is clear, ensuring the reliability of the structure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following non-limiting embodiments are used to illustrate the present invention.

[0025] Embodiment 1:

[0026] Referring to Figures 1 to 3 as shown, a method for slidably connecting a lightweight wallboard infill wall and a structural main body includes a border 1, a first sliding connecting member 2a, a fixed connecting member 2b, a second sliding connecting member 2c, a horizontal beam 4, a flexible filling component 5, a vertical structural member 6, a horizontal structural member 7, and a lightweight wallboard infill wall 8. The flexible filling component 5 includes a heat-insulating and fire-proof material 5a, a caulking material 5b, and an outer shell 5c.

[0027] The vertical vertical structural members 6 and the horizontal horizontal structural members 7 are arranged alternately to form a rectangular wall opening, and the lightweight wallboard infill wall 8 is located in the wall opening. In this application, a slidable connecting component is used to enable the lightweight wallboard infill wall to be slidable in-plane with the structural main body and be stable under the constraint of the structural main body out-of-plane. The horizontal structural member is a structural slab or a structural beam, and the vertical structural member is a structural shear wall or a structural column.

[0028] On both sides of the lightweight wallboard infill wall 8, there are side frames 1. Above the lightweight wallboard infill wall 8, there is a lintel beam 4, and the lintel beam 4 is bolted to the side frames 1 on both sides. Specifically, the side frames 1 are two angle steels that wrap the front and rear end corners of the lightweight wallboard infill wall 8, and the lintel beam 4 is two angle steels that wrap the front and rear end corners of the top of the lightweight wallboard infill wall 8. The angle steels can provide lateral limit protection for the lightweight wallboard infill wall and also provide out-of-plane limit protection for the lightweight wallboard infill wall.

[0029] The upper part of the side frame 1 is horizontally slidably connected to the horizontal structural member 7 through a first sliding connector 2a. The first sliding connector 2a is an L-shaped angle steel fixture. Bolts pass through the oblong holes in the flange at one end of the first sliding connector 2a to connect with the horizontal structural member 7, ensuring that the lightweight wallboard infill wall and the structural main body can freely slide in the plane without collision. Bolts pass through the round holes in the flange at the other end of the first sliding connector 2a to connect with the side frame 1, enabling the upper part of the side frame to slide horizontally relative to the horizontal structural member but not move out of the plane. Since the horizontal oblong holes can only achieve the horizontal sliding of the bolts, the lightweight wallboard infill wall is constrained and stable by the structural main body out of the plane.

[0030] The lower part of the side frame 1 is fixedly connected to the horizontal structural member 7 through a fixed connector 2b. The fixed connector 2b is an L-shaped angle steel fixture. Bolts pass through the round holes in the flanges at both ends of the fixed connector 2b to connect with the horizontal structural member 7 and the side frame 1 respectively, realizing the fixed connection between the lower part of the side frame and the horizontal structural member.

[0031] The lintel beam 4 is horizontally slidably connected to the horizontal structural member 7 through a second sliding connector 2c. The second sliding connector 2c is plate-shaped. Bolts pass through the oblong holes in the second sliding connector 2c and the lintel beam 4 to connect with the horizontal structural member 7, realizing the sliding connection between the lintel beam and the horizontal structural member.

[0032] There is a gap between the side frame 1 and the vertical structural member 6. Inside the gap, there is a flexible filling component 5. The flexible filling component 5 is a cold-formed thin-walled flexible filling component with heat preservation, waterproof, fireproof, and sound insulation functions. Specifically, the flexible filling component 5 includes a housing 5c. Inside the housing 5c, there is heat preservation and fireproof material 5a. In the caulking groove on the housing 5c opposite to the vertical structural member 6, there is caulking material 5b.

[0033] Embodiment 2:

[0034] Reference Figure 3 As shown, a connection component for the method of slidably connecting the above-mentioned lightweight wallboard infill wall and the structural main body includes a side frame 1, a first sliding connector 2a, a fixed connector 2b, a second sliding connector 2c, a lintel beam 4, and a flexible filling component 5. The flexible filling component 5 includes heat preservation and fireproof material 5a, caulking material 5b, and a housing 5c.

[0035] The frame is arranged in two groups that are symmetric left and right, and the crossbeam 4 is connected by bolts between the left and right frames. Specifically, each group of frames 1 consists of two angle steels in the front and back, and the crossbeam 4 consists of two angle steels in the front and back. The angle steels can limit and protect the lightweight wall panel filling wall laterally and also limit and protect it out of plane.

[0036] The upper part of the frame 1 is fixedly connected to the first sliding connector 2a, and the first sliding connector 2a is provided with a sliding connection part. The lower part of the frame 1 is fixedly connected to the fixed connector 2b, and the fixed connector 2b is provided with a fixed connection part.

[0037] The first sliding connector 2a is an L-shaped angle steel fixture. One flange of the first sliding connector 2a is an oblong hole serving as the sliding connection part, and the bolt passes through the round hole of the other flange of the first sliding connector 2a to connect with the frame 1. Since the horizontal oblong hole can only achieve the horizontal sliding of the bolt, the lightweight wall panel filling wall is stable under the restraint of the structural main body out of plane.

[0038] The fixed connector 2b is an L-shaped angle steel fixture. One flange of the fixed connector 2b is a round hole serving as the fixed connection part, and the bolt passes through the round hole of the other flange of the fixed connector 2b to connect with the frame 1, realizing the fixed connection between the lower part of the frame and the horizontal structural member.

[0039] The middle part of the crossbeam 4 is in sliding and fitting connection with the second sliding connector 2c. The second sliding connector 2c is plate-shaped, and the bolts pass through the oblong holes on the second sliding connector 2c and the crossbeam 4 respectively, realizing the sliding connection between the crossbeam and the horizontal structural member.

[0040] The basic examples of the present invention and their respective further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed by the present invention. In the solution of the present invention, each alternative example can be arbitrarily combined with any basic example and alternative example.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
