Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a flexible connection structure of a built-in thermal insulation cast-in-situ concrete filling wall and a frame column beam. Background Art
[0002] At present, the insulation materials in the construction market are of varying quality. Common ones include composite rock wool boards, homogeneous boards, polystyrene particle insulation boards, foamed cement boards, and non-disassembly insulation formwork. Most insulation materials are in the external construction plan. As time goes by, the exterior wall insulation materials have cracked, hollowed, and seeped to varying degrees. Some projects have even fallen off, causing great impact on people's safety and property. The emergence of built-in insulation cast-in-place concrete shear wall structure ("JGJ / T-451-2018 Technical Standard for Built-in Insulation Cast-in-Place Concrete Composite Shear Wall") solves the above hidden dangers and disadvantages, but because its filling wall part has a greater impact on the lateral stiffness of the main structure, its application range is limited to shear wall structures (mostly used in high-rise residential buildings), and is not suitable for flexible connections of other frame structures.
[0003] Therefore, it is particularly important to develop a flexible connection structure with good seismic performance. Utility Model Content
[0004] The purpose of the utility model is to provide a flexible connection structure between a built-in thermal insulation cast-in-situ concrete filling wall and a frame column beam, so as to solve the problems raised in the above background technology.

[0006] The infill wall comprises an infill wall insulation core plate, and both the inner and outer sides of the infill wall insulation core plate are provided with a cast-in-situ reinforced concrete protective layer;
[0007] The outer side of the frame main body is provided with a frame beam and column insulation core plate, and is covered with a cast-in-place reinforced concrete protective layer;
[0008] The insulation core plate of the filling wall and the insulation core plate of the frame beam column are fixed by limiting connectors and steel bar connecting rods;
[0009] The flexible connector includes a U-shaped spring clip, with elastic plates inclined at both ends of the U-shaped spring clip, and a tie rod vertically provided on a side of the middle of the U-shaped spring clip away from the elastic plate, and the tie rod is fixedly connected to the U-shaped spring clip;
[0010] The U-shaped spring clamps the end of the infill wall insulation core plate, and the cross-section of the end of the infill wall insulation core plate is reduced to form an inward-extending corbel of the cast-in-place reinforced concrete protective layer. The inward-extending corbel fits tightly with the flexible connector, and the tie rod passes through the compressible thin plate and is anchored into the interior of the frame main component.
[0011] As a preferred solution, the main frame component is a cast-in-place frame column, and the tie rod of the flexible connector, the limiting connector and the steel bar connecting rod are all anchored into the cast-in-place frame column.
[0012] As a preferred solution, the main frame component is a cast-in-place frame beam, and the tie rod of the flexible connector, the limiting connector and the steel bar connecting rod are all anchored into the cast-in-place frame beam.

[0025] Example 1
[0026] In conjunction with the accompanying drawings, a flexible connection structure of a built-in thermal insulation cast-in-situ concrete infill wall and a frame column beam includes an infill wall 1 and a frame main component, wherein a compressible thin plate 2 is provided between the infill wall 1 and the frame main component and connected by a flexible connector 3;
[0027] The infill wall 1 includes an infill wall insulation core plate 4, and both the inner and outer sides of the infill wall insulation core plate 4 are provided with a cast-in-situ reinforced concrete protective layer 5;
[0028] The outer side of the frame main component is provided with a frame beam and column insulation core plate 6, and is covered by a cast-in-situ reinforced concrete protective layer 5;
[0029] The infill wall insulation core plate 4 and the frame beam column insulation core plate 6 are fixed by limiting connectors and steel bar connecting rods 7;
[0030] The flexible connector 3 includes a U-shaped spring clip 301, with elastic plates 302 inclined at both ends of the U-shaped spring clip 301. A tie rod 303 is vertically provided on the side of the middle of the U-shaped spring clip 301 away from the elastic plate 302, and the tie rod 303 is fixedly connected to the U-shaped spring clip 301.
[0031] The U-shaped spring clip 301 wraps around the end of the filling wall insulation core panel 4, and the cross-section of the end of the filling wall insulation core panel 4 is reduced to form an inward extending corbel 8 of the cast-in-place reinforced concrete protective layer 5. The inward extending corbel 8 fits tightly with the flexible connector 3, and the tie rod 303 passes through the compressible thin plate 2 and is anchored into the interior of the frame main component.
[0032] The main frame component is a cast-in-place frame column 9 , and the tie rod 303 of the flexible connector 3 , the position-limiting connector, and the steel bar connecting rod 7 are all anchored into the cast-in-place frame column 9 .
[0033] The tie rod 303 is welded to the U-shaped spring clip 301 or connected via an anchor bolt.
[0034] In this embodiment, the cross-section of the end of the insulation core board of the infill wall is reduced to form an inward-extending corbel of the cast-in-place reinforced concrete protective layer. The inward-extending corbel fits tightly with the flexible connector, which effectively connects the infill wall and the frame column under normal use, so that the inner plaster layer does not crack. Under the action of seismic loads, the flexible connector makes the infill wall effectively connected to the frame column outside the plane (to prevent the infill wall from tipping over), and relative displacement can occur between the infill wall and the frame column within the plane, thereby reducing the influence of the infill wall on the lateral stiffness of the main structure.
[0035] Example 2
[0036] A flexible connection structure of a built-in thermal insulation cast-in-situ concrete infill wall and a frame column beam, comprising an infill wall 1 and a frame main component, wherein a compressible thin plate 2 is provided between the infill wall 1 and the frame main component and connected by a flexible connector 3;
[0037] The infill wall 1 includes an infill wall insulation core plate 4, and both the inner and outer sides of the infill wall insulation core plate 4 are provided with a cast-in-situ reinforced concrete protective layer 5;
[0038] The outer side of the frame main component is provided with a frame beam and column insulation core plate 6, and is covered by a cast-in-situ reinforced concrete protective layer 5;
[0039] The infill wall insulation core plate 4 and the frame beam column insulation core plate 6 are fixed by limiting connectors and steel bar connecting rods 7;
[0040] The flexible connector 3 includes a U-shaped spring clip 301, with elastic plates 302 inclined at both ends of the U-shaped spring clip 301. A tie rod 303 is vertically provided on the side of the middle of the U-shaped spring clip 301 away from the elastic plate 302, and the tie rod 303 is fixedly connected to the U-shaped spring clip 301.
[0041] The U-shaped spring clip 301 wraps around the end of the filling wall insulation core panel 4, and the cross-section of the end of the filling wall insulation core panel 4 is reduced to form an inward extending corbel 8 of the cast-in-place reinforced concrete protective layer 5. The inward extending corbel 8 fits tightly with the flexible connector 3, and the tie rod 303 passes through the compressible thin plate 2 and is anchored into the interior of the frame main component.
[0042] The main frame component is a cast-in-place frame beam 10 , and the tie rod 303 of the flexible connector 3 , the position-limiting connector, and the steel bar connecting rod 7 are all anchored into the cast-in-place frame beam 10 .
[0043] The tie rod 303 is welded to the U-shaped spring clip 301 or connected via an anchor bolt.
[0044] In this embodiment, the top cross-section of the insulation core board of the infill wall is reduced to form an inward-extending corbel of the cast-in-place reinforced concrete protective layer. The inward-extending corbel fits tightly with the flexible connector, which effectively connects the infill wall to the frame beam under normal use and prevents the inner plaster layer from cracking. Under the action of seismic loads, the flexible connector effectively connects the infill wall to the frame beam outside the plane (to prevent the infill wall from tipping over), and relative sliding can occur between the infill wall and the frame beam within the plane, thereby reducing the impact of the infill wall on the lateral stiffness of the main structure.
[0045] In practice, this utility model utilizes compressible thin plates and flexible connectors to achieve a flexible connection between the infill wall and the frame beams and columns, improving the overall stability and seismic resistance of the building. The insulated core panels of the infill wall and the frame beams and columns not only enhance the structural strength of the infill wall but also improve the building's thermal insulation performance. The standardized configuration of wire mesh and rebar further strengthens the connection between the infill wall and the frame beams and columns, enhancing the overall safety of the building.
[0046] In summary, the utility model solves the problem of flexible connection between the infill wall and the frame beams and columns. On the premise of ensuring normal use function, the infill wall can adapt to the deformation of the main body of the frame structure under the action of seismic load, thereby extending the application scope of the built-in insulation cast-in-place concrete structure to the frame structure.
[0047] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without creatively designing a structure and embodiment similar to the technical solution, they shall fall within the scope of protection of the present invention.
