Abstract
The utility model discloses a steel plate-concrete combination deep beam, including a reinforced concrete slab. The reinforced concrete slab is connected with an inner steel plate through a bolt, and the inner steel plate and the reinforced concrete slab have center alignment. The reinforced concrete slab is deployed on the inner steel plate unilaterally or bilaterally. The utility model is provided with a pre-cast reinforced concrete slab on the external side of the inner steel plate, preventing local buckling of the inner steel plate and overcoming the shortcoming that the steel plate can not give full play to the strength of the plate because of the plate buckling; the steel plate-concrete combination deep beam is connected with the main building through the bolt and can be equipped on the main building without prejudice to the normal use of the main building, particularly applicable to seismic reinforcement and transformation of the building which can not be interfered and can not stop use; the steel plate-concrete combination deep beam can ensure the safety of the main load-bearing structure, such as framework column or beam, through the energy consumption effect, the steel plate-concrete combination deep beam can be easily replaced, with the adaptation of the bolt connection, and the seismic capacity of the structure can be quickly restored.
Description
Technical field
The utility model is a kind of anti-sidesway damping power consumption member of structural engineering technical field, particularly steel plate-concrete combination deep beam.
Background technology
Steel framed structure is made up of vertical frame column and transverse frame beam, and its advantage is that layout is flexible, and bigger architectural space can be provided; But because the size of beam and column is smaller, particularly under the action of horizontal seismic, the lateral displacement of structure is bigger at horizontal loading, anti-side ability a little less than, belong to flexible structure, so its building height is restricted, be unsuitable for building the higher level building.In order to improve the lateral deformation stiffness of structure, build more highrise building, proposed in steel frame, to fill out the form of structure of shear wall, can improve the anti-sidesway ability of structure so significantly; But in framework, arrange the body of wall of comparatively dense, not only increased building weight, make structure be subjected to bigger geological process, also be unfavorable for architectural plane layout and space utilization.In fill out shear wall form mainly contain reinforced concrete shear wall, steel plate shear force wall and steel-concrete compound shear wall.The reinforced concrete shear wall good integrity, rigidity is big, opposing wind load and the earthquake of medium and small level is effective and fireproof performance good; But reinforced concrete shear wall size and from great is born big horizontal force under geological process, the crack occurs early, and the later stage is brittle fracture based on shear failure, and the shake back is difficult for repairing.Steel plate shear force wall bears the seismic forces of appropriateness in earthquake, destroy based on shear yielding, belongs to ductile fracture, and stronger energy dissipation capacity is arranged; But guarantee the ductility of steel plate shear force wall, enough horizontal, longitudinal stiffener need be set, cause steel plate shear force wall manufacturing and working procedure many, cost is higher; In addition, steel plate shear force wall is poor from fireproof performance, needs the additional protection measure.The steel-concrete compound shear wall is made up of steel plate external wrapping concrete, absorbed the advantage of steel plate shear force wall and reinforced concrete shear wall, but the rigidity adjustment to framework still can not realize gradual change amplitude modulation, and variant is unfavorable for the development of material plasticity based on shear strain.
Fill out shear wall in from the steel frame to the steel frame, rigidity amplification is emergent properties, and promptly the endurance and stiffness of clean steel framework is too little, strengthen and fill out shear wall rigidity in the steel frame suddenly, cause dead load bigger, make structure bear bigger geological process, cause structural deterioration easily.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned prior art deficiency, a kind of steel plate-concrete combination deep beam is provided, can satisfy the requirement between two extreme rigidity values of frame construction, the lateral deformation stiffness of amplitude modulation frame construction in a wide range is the efficient means that reduces geological process, improves structure dissipation seismic energy ability.
The technical solution of the utility model is achieved in that the utility model comprises armored concrete slab, and armored concrete slab connects inner layer steel plate by bolt, inner layer steel plate and armored concrete slab center-aligned.
Described armored concrete slab single-sided arrangement or bilateral are arranged on the inner layer steel plate.
The utility model can stop the inner layer steel plate cripling at inner layer steel plate arranged outside precast rc slab, has overcome steel plate because the shortcoming that flexing can not be given full play to intensity; Steel plate-concrete combination deep beam adopts bolt to be connected with main building, can be specially adapted to be subjected to the seismic hardening and the transformation of interference and withdraw from service building (as hospital) not influencing installation under the normal situation about using of building; Steel plate-concrete combination deep beam can be protected main supporting member by the power consumption effect of self, as the safety of frame column, beam, adopts bolt to connect and can change steel plate-concrete combination deep beam easily, recovers the shock resistance of structure rapidly.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is for filling out steel plate-concrete combination deep beam sectional drawing in the steel framed structure.
Below in conjunction with accompanying drawing content of the present utility model is described in further detail.
The specific embodiment
With reference to shown in Figure 1, the utility model is formed by connecting by bolt 4 by inner layer steel plate 1 and armored concrete slab 3, armored concrete slab 3 single-sided arrangement or bilateral are arranged on the inner layer steel plate 1, and the relative position of inner layer steel plate 1 and armored concrete slab 3 is plate center-aligned.And correspondingly evenly reserve identical bolt hole 2 in armored concrete slab 3 upper edge levels and vertical direction according to the position of inner layer steel plate 1 upper bolt hole, guarantee bolt hole 2 center-aligned of reservation on the bolt hole reserved on the inner layer steel plate 1 and the armored concrete slab 3.
With reference to shown in Figure 2, inner layer steel plate 1 and armored concrete slab 3 usefulness bolts 4 link into an integrated entity, constitute steel plate-concrete combination deep beam, inner layer steel plate 1 two ends of steel plate-concrete combination deep beam are connection steel frames beam 5 respectively, inner layer steel plate 1 is connected with steel-frame beam 5 by angle steel 6, angle steel 6 is fixing by high-strength bolt 7 with inner layer steel plate 1, and steel-frame beam 5 is fixing by high-strength bolt 7 with angle steel 6.
Earthquake light plate-concrete combination deep beam dissipation seismic energy destroys earlier, and protection major bearing structures member as the safety of frame column, Vierendeel girder, owing to adopted the bolt connection, can be removed the deep beam of destruction after the earthquake, the deep beam member that more renews easily.
