Description

Technical Field

[0001] The utility model relates to the technical field of assembled building structures, in particular to a flexible connection structure between a concrete filling wall and a main structure. Background Art

[0002] Infill walls are generally set between frame columns, above the floor slab, and below the frame beams. Infill walls are usually built with blocks. In the event of an earthquake, masonry infill walls are easily squeezed and destroyed by the main structure. The strength and rigidity of masonry infill walls are relatively small, and the impact on the main structure is limited. With the promotion and development of prefabricated buildings and building energy-saving technologies, in addition to meeting the enclosure function, infill walls must also meet the reliable fixation of various insulation boards and the strength requirements related to prefabrication and assembly. Therefore, concrete infill walls are used in projects. Due to the high strength and rigidity of concrete infill walls, it is crucial to reasonably design the seams and connections between the infill walls and the frame for the seismic safety of the building structure.

[0003] In engineering practice, in order to ensure that the building structure has good deformation and energy dissipation capacity during earthquakes and reduce the adverse effects of the filling wall on the main structure, it is necessary to adopt corresponding joint structures and flexible connection structures. The joint structure is to leave a certain gap between the secondary structure filling wall and the main structure during construction, and the gap width meets the deformation value requirements under rare earthquakes. At the same time, to ensure that the wall has sufficient bearing capacity under the action of gravity and horizontal forces, it cannot be completely disconnected from the main structure. The flexible connection structure refers to the gap between the secondary structure filling wall and the main structure filled with flexible materials such as polystyrene strips or polyurethane foaming agents, so that the deformation of the main structure is not constrained and affected by the secondary structure.

[0004] At present, there are few studies on the seam connection technology between the infill wall and the main frame. Some seam structures used in projects often cannot meet the requirements of flexible connection and reliable fixation at the same time, resulting in safety hazards such as the infill wall providing greater structural stiffness, the structural calculation being inconsistent with the actual engineering force, and the wall being insufficiently safe under earthquake action.

[0005] Therefore, the applicant has found a solution to the above-mentioned problem through beneficial exploration and research, and the technical solution to be introduced below is produced in this context. Utility Model Content

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0033] Referring to the accompanying drawings, a flexible connection structure between a concrete infill wall and a main structure is shown in the drawings, wherein the concrete infill wall 10 is located in a main structure 20, and the main structure 20 is surrounded by a lower floor beam 21, an upper floor beam 22, a left shear wall 23, and a right shear wall 24.

[0034] The flexible connection structure between the concrete filling wall and the main structure of the utility model comprises a rigid connection structure 100, a left vertical seam 200a, a right vertical seam 200b, a transverse seam 200c, a flexible material 300, and a left connecting rod 400a, a right connecting rod 400b, and a top connecting rod 400c.

[0035] The rigid connection structure 100 is arranged between the bottom surface of the concrete filling wall 10 and the inner bottom surface of the main structure 20 (the upper side of the lower floor beam 22), so that the main structure 20 can effectively support the concrete filling wall 10 without affecting the energy consumption of the support beam. In this embodiment, the rigid connection structure 100 preferably adopts a reinforced concrete cast-in-place connection structure, and the length of the rigid connection structure 100 is generally not more than 1 / 3 of the beam length.

[0036] The left vertical seam 200a, the right vertical seam 200b, and the transverse seam 200c are formed between the left side, the right side, and the top of the concrete filling wall 10 and the left inner side (the inner side of the left shear wall 23), the right inner side (the inner side of the right shear wall 24), and the inner top (the lower side of the upper floor beam 22) of the main structure 20. The seam width of the left vertical seam 200a, the right vertical seam 200b, and the transverse seam 200c needs to be in accordance with the requirements of the inter-layer deformation value under the action of a large earthquake. In this embodiment, the seam width of the left vertical seam 200a, the right vertical seam 200b, and the transverse seam 200c is 30mm to 50mm. In addition, in this embodiment, a water-swelling water stop strip 210 is provided in the middle of the left vertical seam 200a, the right vertical seam 200b, and the transverse seam 200c, which improves the waterproof performance of the overall structure.

[0037] The flexible material 300 is filled in the left vertical seam 200a, the right vertical seam 200b, and the transverse seam 200c, respectively, which can block the interaction between the concrete filling wall 10 and the main structure 20, eliminate the rigidity contribution of the concrete filling wall 10 to the main structure 20, and effectively improve the seismic performance. The flexible material 300 can be a flexible material such as polystyrene board or polyurethane foaming agent. At the same time, the two ends of the left vertical seam 200a, the right vertical seam 200b, and the transverse seam 200c in the horizontal direction are respectively provided with a blocking waterproof material 310, that is, the two sections of the flexible material 300 in the left vertical seam 200a, the right vertical seam 200b, and the transverse seam 200c are provided with blocking waterproof materials, thereby improving the waterproof performance. In this embodiment, the blocking waterproof material 310 is preferably a silicone sealing paste.

[0038] The left connecting rod 400a, the right connecting rod 400b, and the top connecting rod 400c are arranged between the left side, the right side, and the top surface of the concrete filling wall 10 and the left inner side, the right inner side, and the inner top surface of the main structure 20. One end of the left connecting rod 400a, the right connecting rod 400b, and the top connecting rod 400c extend into the concrete filling wall 10 for fixation, and the other end thereof extend into the main structure 20 for fixation. They are used to firmly connect the concrete filling wall 10 to the main structure 20 to ensure that the concrete filling wall 10 does not collapse under the action of a strong earthquake.

[0039] The left connecting rod 400a, the right connecting rod 400b, and the top connecting rod 400c are composed of at least two rows of connecting rods arranged at intervals, and each row of connecting rods is composed of a plurality of connecting rods arranged at intervals along the length direction of the concrete filling wall. The spacing between two adjacent rows of connecting rods is 100mm to 300mm, and the diameter of each connecting rod is 5mm to 10mm. The connecting rods can be made of steel bars or steel strands.

[0040] The flexible connection structure between the concrete filling wall and the main structure of the utility model is also provided with rubber pads 500 at the four corners of the concrete filling wall 10. When an earthquake occurs, the rubber pads can be squeezed and deformed to dissipate energy, thereby reducing the damage to the concrete filling wall 10 or the main structure 20 caused by the earthquake.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
