Description

Technical Field

[0001] The utility model relates to a frame filling wall structure based on a flexible connector, belonging to the field of house building structures. Background Art

[0002] For reinforced concrete frame structures, in traditional construction methods, a rigid connection is adopted between the infill wall and the frame structure. During construction, the bottom of the frame beam is tightly built with inclined masonry, and the infill wall and the frame structure are formed into a whole by setting tie bars and structural columns. The infill wall is constrained by the frame and there is a complex interaction between it and the frame.

[0003] Under the action of earthquake, due to the limitation of infill wall, the frame cannot fully exert its ductility, which easily leads to serious shear failure of column ends, beams or beam-column joints; at the same time, due to the fragility of masonry, the deformation of frame beams and columns squeezes the infill wall, which easily causes the body to break and become unstable or even collapse. GB 50011-2010 "Code for Seismic Design of Buildings" regards infill wall as a non-structural component. In seismic design, the stiffness of infill wall is only considered through periodic adjustment, and the seismic bearing capacity is not taken into account. This simplified treatment method cannot consider the influence of different walls on the seismic performance of the structure. In the high-intensity earthquakes that have occurred in recent years, the infill wall frame structure has been severely damaged, causing huge economic losses and casualties.

[0004] In order to reduce the interaction between the filling wall and the frame structure, the utility model is specially proposed. Summary of the invention

[0005] The utility model provides a frame filling wall structure based on flexible connectors, which realizes the construction of the frame filling wall structure through ingenious design of the flexible connector structure and reasonable layout, and reduces the adverse effects of earthquake action on the filling wall.

[0006] The technical solution of the utility model is:

[0007] A frame infill wall structure based on a flexible connector comprises a left frame column 1, a right frame column 3, an upper frame beam 2, an infill wall 4, a lower base 5 and a flexible connector 6, wherein the left frame column 1 and the right frame column 3 are arranged on the lower base 5 in a vertical direction, the infill wall 4 is between the left frame column 1 and the right frame column 3, and the upper part of the infill wall 4 is an upper frame beam 2 which is integrated with the infill wall 4 and is used to connect the left frame column 1 and the right frame column 3, and the left frame column 1, the right frame column 3, the lower base 5 and the infill wall 4 are connected by a flexible connector 6; the flexible connector 6 comprises a rubber middle plate 6-1 and rubber ribs, and the rubber ribs extending along the rubber middle plate 6-1 on both sides are used to connect the left frame column 1, the right frame column 3, the lower base 5 and the infill wall 4.

[0008] The rubber ribs include an upper middle rib 6-2, an upper top rib 6-3, a lower middle rib 6-5, and a lower top rib 6-4. The upper middle rib 6-2 and the lower middle rib 6-5 are rectangular convex strips symmetrically arranged on both sides of the rubber intermediate plate 6-1. The upper top rib 6-3 is a first trapezoidal convex strip extending from the upper middle rib 6-2 in a direction away from the rubber intermediate plate 6-1, and the lower bottom of the first trapezoidal convex strip is on the side away from the rubber intermediate plate 6-1. The lower top rib 6-4 is a second trapezoidal convex strip extending from the lower middle rib 6-5 in a direction away from the rubber intermediate plate 6-1, and the lower bottom of the second trapezoidal convex strip is on the side away from the rubber intermediate plate 6-1.

[0009] The number of the rubber ribs is plural.

[0010] The flexible connector 6 between the lower base 5 and the filling wall 4 is of solid structure, the rubber middle plate 6-1 of the flexible connector 6 between the left frame column 1, the right frame column 3 and the filling wall 4 is of hollow or solid structure, and the rubber rib is of solid structure.

[0011] The flexible connecting piece is made of synthetic rubber, recycled rubber, or a mixture of natural rubber and recycled rubber.

[0012] The beneficial effects of the utility model are:

[0013] First, the utility model adopts a flexible connector with an ingenious structural design as a connecting member between the main structural member and the infill wall, which can effectively protect the infill wall when the overall structure is subjected to an earthquake, can buffer the collision between the frame column and the infill wall, and reduce the squeezing, pulling, and shearing effects of the main structural member on the infill wall.

[0014] Second, the flexible connector in the utility model realizes the connection between the flexible connector and the external frame and the filling wall by setting ribs of middle rib + top rib. The ribs can play the role of bayonet and are connected between the filling wall and the external frame, thereby effectively improving the function of the flexible connector and further exerting the anti-pullout and anti-shear effects of the flexible connector to reduce the adverse effects of earthquake on the filling wall.

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments, but the content of the utility model is not limited to the described scope.

[0025] Example 1: Figure 1-Figure 8 As shown, a frame infill wall structure based on a flexible connector comprises a left frame column 1, a right frame column 3, an upper frame beam 2, an infill wall 4, a lower base 5 and a flexible connector 6, wherein the left frame column 1 and the right frame column 3 are arranged on the lower base 5 in a vertical direction, the infill wall 4 is arranged between the left frame column 1 and the right frame column 3, and the upper part of the infill wall 4 is an upper frame beam 2 which is integrated with the infill wall 4 and is used to connect the left frame column 1 and the right frame column 3, and the left frame column 1, the right frame column 3, the lower base 5 and the infill wall 4 are connected by a flexible connector 6; the flexible connector 6 comprises a rubber middle plate 6-1 and rubber ribs, and the rubber middle plate 6-1 has rubber ribs extending on both sides thereof and is used to connect the left frame column 1, the right frame column 3, the lower base 5 and the infill wall 4.

[0026] Furthermore, the rubber rib includes an upper middle rib 6-2, an upper top rib 6-3, a lower middle rib 6-5, and a lower top rib 6-4. An upper middle rib 6-2 and an extended upper top rib 6-3 constitute a complete heterogeneous rib, and a lower middle rib 6-5 and an extended lower top rib 6-4 also constitute a complete heterogeneous rib; the upper middle rib 6-2 and the lower middle rib 6-5 are rectangular convex strips symmetrically arranged on both sides of the rubber intermediate plate 6-1, the upper top rib 6-3 is a first trapezoidal convex strip extending from the upper middle rib 6-2 in a direction away from the rubber intermediate plate 6-1, and the lower bottom of the first trapezoidal convex strip is on the side away from the rubber intermediate plate 6-1, and the lower top rib 6-4 is a second trapezoidal convex strip extending from the lower middle rib 6-5 in a direction away from the rubber intermediate plate 6-1, and the lower bottom of the second trapezoidal convex strip is on the side away from the rubber intermediate plate 6-1.

[0027] Furthermore, the number of the rubber ribs is multiple. The number of the rubber ribs can be multiple, Figures 1 to 8 Shown is a flexible connector with 6 integral anisotropic ribs.

[0028] Furthermore, the material of the flexible connecting member may be synthetic rubber, recycled rubber, or a mixture of natural rubber and recycled rubber.

[0029] Furthermore, the flexible connector 6 between the lower base 5 and the infill wall 4 adopts a solid structure, the rubber middle plate 6-1 of the flexible connector 6 between the left frame column 1, the right frame column 3 and the infill wall 4 adopts a hollow or solid structure, and the rubber rib is a solid structure. When the thickness of the rubber middle plate 6-1 of the flexible connector between the left frame column 1, the right frame column 3 and the infill wall 4 meets the strength requirements, a hollow structure can be adopted.

It should be noted that the size, number of ribs, and arrangement of the utility model can be designed according to the size of the specific infill wall. According to the actual use requirements of the scene, it is possible to consider arranging tie bars at the connection between the left frame column 1, the right frame column 3 and the infill wall 4, that is, the tie bars pass through the flexible connector 6 to connect the left frame column 1 and the infill wall 4, and the right frame column 3 and the infill wall 4.

[0031] Furthermore, the intermediate filling wall 4 is cast in situ. For the example of cast-in-situ filling wall, the flexible connector is located at the left and right sides and bottom of the filling wall in the overall structure, such as Figure 4 The frame-filled wall structure based on flexible connectors is shown as an integrated schematic.

[0032] The construction sequence of the utility model during construction is: first, the bottom cap 5 is molded, reinforced, and poured, and the bottom flexible connector 6 is installed before the concrete is solidified, and then the beams and columns and the filling wall steel bars are tied, and the vertical flexible connector 6 is placed at the same time, so that the steel bars in the column and the steel bars in the wall are in close contact with the flexible connector, and then the overall pouring is performed. The construction diagram is shown in Figure 8 shown.

[0033] By applying the above technical solution, it can be seen that the utility model has the characteristics of simple structure, mature manufacturing process, wide application range and high practicality.

[0034] Specifically, the left and right frame columns and the upper frame beam are used to bear the vertical loads, vertical loads, earthquake effects, etc. acting on the frame. The infill wall is set between the two frame columns and only serves as a enclosure. It does not bear any other loads except its own weight. The infill wall and the external frame are tightly connected through the proprietary rib flexible connector, which further plays the role of anti-pulling, anti-compression, and anti-shear to reduce the adverse effects of earthquake on the infill wall. The flexible connector is made of rubber material, which has the characteristics of good ductility, high strength, and good durability.
