Description
Technical field
The present invention relates to the stair field in steel work.
Background technology
Steel work has the advantages such as deadweight is light, short construction period, anti-seismic performance are good, but cost is higher, and along with social development, steel building gets more and more.Relative to concrete frame structure, steel framed structure anti-side rigidity is less, under geological process, the lateral deformation of steel framed structure is larger, if adopt conventional stair, when particularly adopting reinforced concrete stairs, the waist slab of inclination becomes the skewed horizontal load of agent structure, bear larger horizontal force, stair are destroyed.Also lack the quakeproof stair being applicable to steel work at present, therefore, need a kind of novel quakeproof stair and construction method, in steel building.
Summary of the invention
In order to solve the shockproof problem of stair in steel work, the present invention discloses a kind of combining structure quakeproof stair and construction method, can adapt to the feature of steel work, has again good shockproof effect.
The technical scheme of combining structure quakeproof stair of the present invention is: combining structure quakeproof stair is made up of waist slab, halfpace plate, floor levels plate, inner platform beam, outer platform beam, floor levels beam, platform column, separation layer, weather strip, deformation block, support bracket, Vierendeel girder and frame column; Waist slab and halfpace plate are reinforced concrete member, floor levels plate is composite floor, inner platform beam, outer platform beam, floor levels beam, platform column, support bracket, Vierendeel girder and frame column are steel beam column, the main body of above-mentioned component composition combining structure quakeproof stair; Waist slab one end and floor levels plate affixed, the other end and halfpace plate affixed, the lateral surface of waist slab and the medial surface of Vierendeel girder are in same vertical plane; Floor levels plate is bearing on floor levels beam and Vierendeel girder; Halfpace plate is overlapped on inner platform beam and outer platform beam, lap-joint is provided with separation layer, halfpace plate is divided into two parts, every part is connected with one piece of waist slab respectively, the gap of halfpace plate is filled with weather strip, the lateral surface of halfpace plate and the medial surface of Vierendeel girder are in same vertical plane, halfpace plate does not contact with the edge of a wing end face of frame column, distance is 200 millimeters, the edge of a wing contacts side surfaces of halfpace plate and frame column, space between halfpace plate and frame column is filled with deformation block, and halfpace plate stretches out outer platform beam and is not less than 200 millimeters; Inner platform beam support is on platform column, and platform column is bearing on Vierendeel girder; Outer platform beam support is on support bracket, and support bracket is fixed on the edge of a wing of frame column; Floor levels beam support is on Vierendeel girder; Vierendeel girder is bearing on frame column.Floor levels plate adopts profiled steel sheet combination floor, and profiled sheet adopts closed type template, and the fin of press type steel plate is laid perpendicular to floor levels beam direction.Deformation block adopts foamed plastics, has good deformation performance.Separation layer adopts plastic sheeting, makes not produce adhesion stress between the concrete of halfpace plate and girder steel, can relative sliding relatively easily.
Because halfpace plate is divided into two parts, so not contact between two pieces of waist slabs, can relative motion.During geological process, relative storey displacement can be produced between two floors, the floor levels plate of lower floor, waist slab and a part of halfpace plate are with lower floor's superstructure associated movement, the flooring landing slab on upper strata, waist slab and a part of halfpace plate are with upper strata superstructure associated movement, because halfpace plate is overlapped on inner platform beam and outer platform beam, and there is separation layer, so can relative sliding, therefore the waist slab tilted can not become the skewed horizontal load of agent structure, the horizontal loading that stair are born is very little, can not cause damage to stair.Between frame column and halfpace plate, arrange deformation block, object is the demand in order to satisfied distortion, produces active force after avoiding frame column to contact with halfpace plate.Halfpace plate stretches out outer platform beam and is not less than 200 millimeters, and object is the demand in order to satisfied distortion, makes halfpace plate can not from landing outer platform beam.Outer platform beam support is on support bracket, and object is moved in outer platform beam to make, and halfpace plate when avoiding earthquake on outer platform beam contacts with exterior wall.Floor levels plate adopts profiled steel sheet combination floor, floor levels plate can be connected well with this floor lid, profiled sheet adopts closed type template, and the fin of press type steel plate is laid perpendicular to floor levels beam direction, and the reinforcing bar of waist slab can be made to be anchored at well in floor levels plate.
The construction method of combining structure quakeproof stair of the present invention is: the first step, machined steel component, at support bracket, connect processing bolt hole on bracket, connection stiffening rib, inner platform beam, outer platform beam, floor levels beam and Vierendeel girder, on frame column Weld-supporting bracket be connected bracket, platform column is welded to connect bracket, on Vierendeel girder jig column be connected stiffening rib; Second step, by Vierendeel girder by bolt and solder design on frame column, floor levels beam is bolted on Vierendeel girder, by inner platform beam by bolt and solder design on platform column, outer platform beam is bolted on support bracket; 3rd step, the floor levels beam and Vierendeel girder of lower floor lay profiled sheet, welding pin, install the template of lower floor's waist slab and part halfpace plate, separation layer is laid in the contact position of halfpace plate and inner platform beam and outer platform beam, assembling reinforcement, builds the concrete of the floor levels plate of lower floor, waist slab and part halfpace plate together with lower floor superstructure; 4th step, the floor levels beam and Vierendeel girder on upper strata lay profiled sheet, welding pin, install the template of upper strata waist slab and part halfpace plate, separation layer is laid in the contact position of halfpace plate and inner platform beam and outer platform beam, assembling reinforcement, builds the concrete of the floor levels plate on upper strata, waist slab and part halfpace plate together with the superstructure of upper strata; 5th step, the surface layer of construction waist slab, halfpace plate and floor levels plate, installs weather strip and deformation block.
The halfpace plate of combining structure quakeproof stair of the present invention and have separation layer between inner platform beam and outer platform beam, halfpace plate can be slided under geological process, therefore waist slab can not become the skewed horizontal load of agent structure, bear very little horizontal loading, ensure that the safety of stair, and combining structure quakeproof stair can be connected well with agent structure, formed overall.Described construction method can ensure the slip of halfpace plate under geological process, simultaneously by setting-up of construction joint on halfpace plate, ensure that globality and the stress performance of waist slab.The present invention can adapt to the feature of steel work, alleviates the earthquake of stair during earthquake, has larger social benefit.
