Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of earthquake-proof and earthquake-resistant construction of buildings, in particular to a flexible connection frame filling wall. Background Art
[0002] When constructing a building frame structure, first connect the beams and columns to form a load-bearing frame, and then use bricks and concrete blocks to build infill walls to separate the space. With the advancement of technology, the industry has adopted a solution that does not require building walls but directly uses large-area reinforced concrete sandwich panels as wall panels, that is, prefabricates several vertical strips of the same height as the wall surface, and then workers install and fix the strips to the frame one by one, and arrange them in a row to form a complete infill wall surface.
[0003] The above-mentioned building frame structure has an obvious shortcoming, that is, the infill wall and the beams and columns of the frame are rigidly connected. During an earthquake, the vibration of the beams and columns of the frame will shear and damage the infill wall. To overcome this shortcoming, some people in the industry have proposed the idea of setting a circle of gelled elastic body between the frame structure and the infill wall to reduce vibration and isolate earthquakes.
[0004] However, this concept is difficult to implement on a large-scale wall made of slats, because a gap needs to be left between the slats and the frame for applying the gelling elastomer mortar, so the slats and the frame cannot touch each other, and naturally the slats and the frame cannot be fixed, so construction is impossible. Therefore, this concept can only be implemented on traditional infill walls constructed with blocks, that is, after the bricks and blocks are laid, mortar with rubber particles is applied and bonded to the gap between the infill wall and the frame. However, this construction method is inefficient, slow, and has high labor costs. The degree of prefabrication of each component is also low, and the connection strength between the wall, frame, and gelling elastomer is also weak, and the structural stability is not strong. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a flexible connection frame filling wall which can avoid the filling wall being damaged by frame shearing and compression in an earthquake, has convenient and fast construction, a high degree of prefabrication, and each component is firmly and stably assembled.
[0006] The technical solution of the utility model is to provide a flexible connection frame filling wall, which includes a crossbeam and a column, each column is formed by a plurality of prefabricated column sections connected from bottom to top, and the lowest column section is fixed on the foundation of the building; a crossbeam corresponds to two adjacent column sections of the same floor height, and the crossbeam includes the butted beam sections on both sides and the normal beam section in the middle, and the two ends of the normal beam section are screwed with the butt beam sections on both sides through a first connecting steel plate, and the butt beam sections on both sides are respectively welded to the column sections on the same side; there is also a complete A wall panel, the top surface of which is provided with transverse convex strips or transverse grooves, and the two side surfaces of the wall panel are provided with longitudinal convex strips or longitudinal grooves; an elastic column is spot-welded and fixed on the inner side of each column section, and a longitudinal groove or longitudinal convex strip is provided on the inner side of each elastic column; the inner side of each elastic column is male-female clamped with the corresponding side surface of the adjacent wall panel; an elastic beam is spot-welded and fixed on the lower side of each normal beam section, and a transverse groove or transverse convex strip is provided on the lower side of each elastic beam, and the lower side of each elastic beam is male-female clamped with the top surface of the lower wall panel; the elastic column and the elastic beam are made of high-ductility concrete material.
[0007] Compared with the prior art, the above flexible connection frame filling wall has the following advantages.
[0008] First, two elastic columns and an elastic beam form a highly ductile N-shaped shock-absorbing and seismic isolation structure, which separates and protects the wall panel and the beam-column frame, avoids direct rigid contact between them, and protects the wall panel from shear and compression damage during an earthquake.
[0009] Moreover, the above-mentioned components are all prefabricated parts with a high degree of assembly. Compared with cast-in-place structures, the construction is convenient, fast and efficient. In particular, the crossbeam is made into a semi-enclosed structure, which is screwed by a normal beam section and a butt beam section. In this way, after assembling the column section and elastic column of the floor height, the entire wall panel can be quickly hoisted along the longitudinal groove by a crane. The wall panel is hoisted first and then the crossbeam is closed to fix the frame. In the prior art, the frame has been completed before the wall panel is constructed. It is a fully enclosed frame, which is blocked by the crossbeam and cannot be hoisted. Therefore, workers can only carry the strip panels one by one and assemble them into the door frame one by one. In comparison, the construction process of the filling wall of this application is obviously more time-saving and labor-saving.
[0010] Furthermore, since the assembly between various components is firm and reliable, such as the screw connection between the left and right column sections and the normal beam sections, the spot welding of each column section and the elastic column on the same side, the spot welding of the normal beam section and the elastic beam, and the wall panels are respectively connected to the elastic beams and elastic columns through transverse and longitudinal convex strips...therefore, the overall strength, firmness and durability of the infill wall are relatively ideal, and its service life is long.
[0011] Preferably, each butt-jointed beam section is screwed to the normal beam section via four first connecting steel plates at the upper, lower, front and rear ends; the top of each elastic column and the left and right ends of the elastic beam are hollowed out with a lower working opening for accommodating the lower first connecting steel plate and bolts; the bottom end of the upper elastic column and the left and right lower corners of the upper wall panel are hollowed out with an upper working opening for accommodating the upper first connecting steel plate and bolts; this ensures that the butt-jointed beam section and the normal beam section are firmly and reliably connected, and reserves upper and lower working space to facilitate tightening and loosening the bolts and installing the connecting steel plate at this position, making the assembly operation easier.
[0012] As another preferred embodiment, four upper ear plates are provided at the top end of the lower column section, and four lower ear plates are provided at the bottom end of the upper column section. The four lower ear plates of the upper column section and the four upper ear plates of the lower column section are screwed together through four second connecting steel plates at the front, rear, inside and outside; the lower part of each elastic column is hollowed out with a side working opening for accommodating the inner second connecting steel plate and bolts; this can ensure that the upper and lower column sections are firmly and reliably connected, and side working space is reserved to facilitate tightening and loosening the bolts and installing the connecting steel plates at this position, making the assembly operation easier.
