Description
Technical Field
The invention belongs to the technical field of buildings, and particularly relates to a flexible connection method of a filler wall and a frame structure.
Background
Frame construction has advantages such as plane layout is nimble, the interior space is big, and frame construction generally builds infilled wall by laying bricks or stones and carries out space division and outside enclosure, and common wall body material has: standard building blocks, light hollow bricks, autoclaved fly ash building blocks, aerated concrete building blocks and the like.
The connection between the filler wall and the frame beams and columns can adopt rigid connection and flexible connection, for example, the filler wall and the frame of a civil frame structure house are rigidly connected, the connection between the filler wall and the frame is enhanced by a masonry method of obliquely building and jacking a brick wall or a method of setting tie bars, then embedding the tie bars with mortar and setting constructional columns in the wall, and the connection mode is favorable for the integral stability of the filler wall and is favorable for sound insulation, heat preservation and heat insulation. Under the action of earthquake, the filler wall has certain shock resistance.
The infilled wall flexibly connected with the frame is mainly used in structural systems such as industrial plants with small lateral force resisting rigidity of main structures, such as portal rigid frame structures. The deformation of the structure is large under the action of wind load or earthquake, the deformation resistance of the filler wall is poor, the design intention of adopting flexible connection is to reduce the external force action of the beam column of the main structure to the filler wall to the minimum under the action of the wind load, and meanwhile, the flexible connection can ensure that the filler wall does not collapse and hurt people under the action of the earthquake. The flexible connection infilled wall has two kinds of structural arrangement mode: embedded and bonded. The embedded type is that the infilled wall is built in the same plane of the frame in blocks, the periphery of the infilled wall is connected with the frame through thin steel bars, and elastic materials are filled to meet the requirements of building functions. The adhesive filling wall is built on the frame edge, is not in the same plane with the frame, is a whole wall body, can meet the requirements of building functions, and is connected with the frame through a connecting piece with a specific structure.
The connection measure between the adhesive filling wall and the frame needs to ensure that the deformation of the frame does not cause the damage to the wall due to the overlarge effect on the wall under the action of wind load, but the strength of the adhesive filling wall needs to meet the requirement of being capable of pulling the filling wall when in earthquake action so as to prevent the filling wall from collapsing and damaging. The flexible connection principle is specified in the current building design specifications, and some flexible connection implementation measures are given in the relevant drawings in a centralized manner, but in the actual building use process, due to the action of wind load, more cases of serious damage of the filler wall occur, the engineering maintenance cost is very high, and the design defects of the flexible connection measures of the filler wall are explained.
Chinese patent CN108222283A discloses a flexible connection structure of a filler wall and a main body frame, which comprises a connecting piece I pre-embedded in a frame column or a frame beam and a connecting piece II connected with the connecting piece I; the connecting piece I consists of a vertical plate and anchor bars; anchor bars are uniformly arranged on one surface of the vertical plate, and the other surface of the vertical plate is connected with a connecting piece II; and a rib penetrating hole for penetrating the rib is formed in the connecting piece II. The attachment mechanism used in this patent is a tendon. The anchor bar connection mode is a connection mode which is completely separated in a normal use state and is not a flexible connection mode, but the inertia force of the filler wall can generate impact force on the connection anchor bar under the action of an earthquake, and the sudden brittle failure of the wall body can be caused.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a flexible connection method of a infilled wall and a frame structure, which can ensure that the acting force of the frame on the wall is small under the action of wind load; under the action of an earthquake, the wall body and the frame work cooperatively to prevent collapse and hurt people, and the earthquake-proof wall body and the frame are a connection form which has definite force transmission, simple structure, safety, reliability and convenient construction.
The purpose of the invention can be realized by the following technical scheme:
a flexible connection method for a filler wall and a frame structure is characterized in that a damper is adopted to connect the filler wall and the frame structure, joint bearings at two ends of the damper are respectively connected to two hinged supports through pin shafts, one hinged support is fixed on a beam column of the frame structure, and the other hinged support is connected to the filler wall.
The dampers are provided with a plurality of dampers which are horizontally and/or vertically and uniformly distributed between the filler wall and the frame structure.
Preferably, the damper is a viscous fluid damper.
More preferably, the damper is a velocity-dependent viscous fluid damper, which is made based on the principle that a fluid generates viscous resistance when passing through an orifice, and is composed of a cylinder sleeve, a damping medium, a piston rod, a joint bearing, and the like.
The hinged support is connected with the frame beam and the column through welding or bolts for the steel structure frame; for reinforced concrete frames, the frame beams and columns are connected by anchor bolts.
The hinged support is anchored on the filling wall through a bolt.
The frame structure is a steel frame structure or a concrete frame structure.
The filler wall comprises a traditional masonry filler wall, a novel light masonry filler wall or a precast concrete block filler wall.
The adopted viscous damper is a speed type damper, and when the relative speed between the main body structure and the filler wall is high, the output force of the damper is high; when the relative speed between the main body structure and the filler wall is small, the output force of the damper is small; the damping force is independent of the relative displacement of the two ends, and the energy is dissipated by the damper under the damping action during working. This mechanical property of the damper makes it particularly suitable for connecting a body structure to a filler wall: (1) under the normal windless and earthquake-free use state, the damper does not work; (2) under the action of wind load, the main body structure and the filler wall have larger relative displacement and smaller speed, and at the moment, the damper has larger running stroke, but the damping force is very small, so that large acting force cannot be generated on the filler wall; (3) under the action of an earthquake, the relative speed is high, the damper plays a role in buffering the earthquake inertia force of the wall body, the filled wall is pulled by the damper at the moment, the filled wall is not collapsed in the earthquake process, and meanwhile, part of earthquake energy is dissipated by the damper.
Compared with the prior art, the flexible connection method improves the prior flexible connection technology and has wide market popularization and application prospects. Under the normal use state, the filler wall meets the building function requirements and plays a role in space separation; under the action of wind load, the main body frame deforms greatly, but has little effect on the filler wall, and the filler wall cannot crack and other damages; and when the earthquake happens, the viscous damper coordinates the interaction between the frame and the filler wall to ensure that the filler wall is not collapsed and damaged.
