Description

A kind of closed-section steel deck combined concrete shear wall connecting node
Technical field
The utility model relates to a kind of closed-section steel deck combined concrete shear wall connecting nodes, belong to building structure Field.
Background technique
Shear wall is most common a kind of lateral resistant member in skyscraper, and conventional steel bar concrete shear wall is with its entirety Property it is good, rigidity is big, lateral deformation is small, resist the advantages that wind load and medium and small grade earthquake effect are prominent and fire protecting performance is good, by The favor of numerous engineers and technicians.But reinforced concrete shear wall rigidity is big, and biggish level is born under seismic force effects Power, crack generation is more early, and the later period, ductility was small, energy dissipation capacity is poor based on failure by shear, is in brittle break, is not easily repaired after shake. Steel plate-concrete combined shear wall improves the deficiency of reinforced concrete shear wall, steel plate and concrete composite to a certain extent Shear wall, which refers to, is arranged steel plate in concrete two sides, by shear connector junction steel plate and concrete, makes the two as a whole It works together, steel plate-concrete combined shear wall shear-carrying capacity with higher, good ductility and energy dissipation capacity.But it wants Guarantee that steel plate-concrete combined shear wall light plate is cut buckling failure, guarantee that steel plate works together as a whole with concrete, Shear connector or the intensive ribbed stiffener of setting need to be covered on the steel plate, cause the design, manufacture and construction of shear wall complicated, cost Increase;It is simultaneously processing, production and the installation accuracy requirement for guaranteeing steel plate, " steel plate shear force wall technical regulation " (JGJ/T380- 2015) minimum thickness of unilateral steel plate is not preferably less than 10mm, and thickness of wall body in clear stipulaties steel plate-concrete combined shear wall It is not preferably less than 250mm, limits application of the steel plate-concrete combined shear wall in multi- story and high- rise building.In addition, to prevent from pouring It builds Concrete light plate and the mould phenomenon that rises occurs, a large amount of supports need to be set in steel plate two sides, increase the complexity of construction.It closes Shape of the mouth as one speaks profiled sheet compound shear wall, which efficiently solves, needs setting to socket key in double steel plate combined concrete shear wall, construction is complicated The problem of, using the geometrical property of closed-section steel deck itself, when casting concrete, closed-section steel deck has biggish Out of plane stiffness is able to satisfy the demand of casting concrete, and after concrete hardening, closed-section steel deck is embedded in concrete Portion can effectively anchor profiled sheet, avoid the problem of setting shear connector is needed in common double steel plate shear wall, while silent Type profiled sheet thickness can be adjusted accordingly according to bearing capacity and anti-side rigidity demand, compensate for steel in double steel plate shear wall The excessive problem of plate thickness, it is more economical, reasonable.Since closed type floor is inside wall, and steel plate is relatively thin, connection compared with For difficulty, thus the connection of closed-section steel deck compound shear wall medium-pressure type steel plate be limit its engineer application critical issue it One.
Utility model content
The utility model is to overcome the shortcomings of the existing technology, propose that a kind of stress is clear, closed type die mould steel easy for construction Plate concrete combined shear wall connecting node.
The utility model adopts the technical scheme that in order to solve the above problem:
A kind of closed-section steel deck combined concrete shear wall connecting node, it includes first edge stiffener, Two Edge Enhancement components, closed-section steel deck, shear connector, bar dowel, node connecting plate and concrete;
First edge stiffener and second edge stiffener are arranged side by side, first edge stiffener and second edge Two opposed closed-section steel decks, and first edge stiffener, the second side is respectively arranged in two sides up and down between stiffener Edge stiffener is connected with closed-section steel deck three surrounds a hollow building enclosure, on closed-section steel deck inner surface It is respectively provided with a plurality of rib of slab along longitudinal direction, a plurality of rib of slab interval is arranged, welding short steel rod at the top of the rib of slab of closed-section steel deck, and One end of the bar dowel is stretched out at the docking of two closed-section steel decks of the same side, guarantees that the internal force of top floor effectively passes Lower part floor is passed, node connecting plate is equipped at two closed-section steel deck docking of the same side, is set in hollow building enclosure There is the shear connector being connected with first edge stiffener and second edge stiffener, has been poured in hollow building enclosure mixed Solidifying soil.
The beneficial effect of the utility model compared with prior art is: closed-section steel deck combined concrete shear wall is by two Side closed-section steel deck, concrete and edge constraint component composition, the fin of closure are divided into profiled sheet multiple vertical Strip makes general steel plate be changed into multiple strips by being cut in integral planar and individually cut.Preliminary analysis shows: closed type die mould Steel plate concrete combined shear wall utilizes the compound action of profiled sheet and concrete, can give full play to two kinds of materials itself is excellent Gesture shows higher bearing capacity, good energy dissipation capacity and deformability under lateral force and longitudinal force collective effect.It closes Degree of lip-rounding fin is embedded in inside concrete, can effectively anchor profiled sheet, is it is not necessary that shear connector is arranged in hollow building enclosure It can guarantee that profiled sheet and concrete work together as a whole;Silent shape fin can be used as effective support of steel plate, improve Stability of the profiled sheet under vertical force and reciprocal horizontal load action, significantly improves the bearing capacity of profiled sheet;This Outside, profiled sheet has biggish out of plane stiffness, and the only a small amount of support of setting can meet construction requirement, and it is difficult to reduce construction Degree.The connecting node construction method of the utility model overcomes profiled sheet thinner thickness, more tired using butt weld connection Difficult problem.The utility model solves the problems such as existing Seismic Behavior of Reinforced Concrete Walls Strengthened is poor, easy to crack;Avoid steel Be arranged that a large amount of shear connectors, steel plate thickness be excessive in plate-combined concrete shear wall and concreting process in easily rise The problems such as mould;Affixed bar dowel and node connecting plate, solve profiled sheet in succession at the rib of slab of closed-section steel deck The place's of connecing intensity is not easy the problem of guaranteeing.
