Description

A kind of Business Building top level structure
Technical field
The present invention relates to building field, more particularly to a kind of Business Building top level structure.
Background technology
Traditional top floor uses primary and secondary girder construction, and girder has to increase height due to bearing very big load, due to top Layer structure is effectively using the height that space is beam bottom to lower floor floor, which limits the use function of top floor, if will Bearing beam makes the identical beam of height into, it is clear that depth of beam can be reduced, but this can cause the variation of load-carrying construction power transmission path, If unreasonable can cause stress raisers to cause safety accident.The equipment such as pendent lamp are arranged among some Business Buildings, if Centre can be reduced in the case of having beam effectively using space, and how to promote Business Building top layer is engineering staff effectively using space The subject faced.
Invention content
The purpose of the present invention is to provide a kind of Business Building top level structure effectively space is used to solve Business Building top layer not The problem of big.
Arched girder, bearing beam and grid beams are provided below in roof boarding in the present invention, these beams form cancelled structure and play The effect of integrated carrying, and adapted to the requirement of large space among roof boarding, arched girder is by upper load reasonable conversion into uniformly distributed Load passes to intermediolateral column, and installs anti-seismic construction on intermediolateral column top.Due to only having roof boarding among the structure, rigidity is opposite It is poor, structure destruction is susceptible under the action of seismic force, the power that especially intermediolateral column upper node is subject to will be very big, therefore Effective seismic countermeasure is used to intermediolateral column.
Arched girder is provided below in roof boarding, and arched girder can not only bear the vertical lotus that roof boarding passes over during load-bearing It carries, while also suffers from the thrust that grid beams pass over, so to take effective technical measures at antitorque aspect.Arched girder is cut Using up-small and down-big trapezoidal, trapezoid cross section is conducive to increase the torsional moment inertia of arched girder in face, trapezoidal upper edge lengths for 400~ 600mm, trapezoidal lower edge lengths are 500~800mm, set the antitorque stirrup of double limbs, and the antitorque stirrup spacing of arched girder is 50mm, and arched girder is cut Middle face sets antitorque reinforcing bar, and the anchorage length that the antitorque reinforcing bar of arched girder stretches into intermediolateral column reaches 45~50 times of antitorque bar diameters, Arched girder is made to obtain the very big rigid mount of a torsional rigidity by the abundant anchoring of antitorque reinforcing bar.Arched girder is ellipse or circle Shape, oval axial length are 3~8m, and circular diameter is 3~6m, and the control of arched girder amount of deflection is 1/250~1/400, and arched girder is provided below The distance between intermediolateral column, adjacent intermediolateral column is 0.75~1.8m, and side column is provided below in side bar, and side column is lateral or perpendicular for intermediolateral column To side position, bearing beam is set, and load beam width is 300~500mm between side column and intermediolateral column.Arched girder, bearing beam, side bar The roofing span of slab of formation can be larger, roofing span of slab can because span is excessive and cracking or the phenomenon that amount of deflection is excessive, therefore Grid beams are provided below in the position roof boarding that arched girder, bearing beam, side bar are formed, grid beam width is 200~350mm, works as arch When depth of beam is less than 600mm, arched girder, bearing beam, side bar, grid depth of beam are all higher than 300mm or less than 600mm, loads The identical coordination stress that can strengthen between each component of beam, side bar, grid depth of beam.When arched girder is greater than or equal to 600mm, Arched girder, bearing beam, side bar are highly all higher than 600mm or less than 800mm, and grid depth of beam is less than or equal to 600mm.
It cannot regard the hold-down support of grid beams at the lattice point of both direction grid beams intersection point as, but the elasticity of grid beams Bearing, grid beams are hold-down support only at two supports.Thus the grid beams of both direction are in cloth muscle, below grid beams Longitudinal tensile reinforcing bar cannot be disconnected at lattice point, and both ends bearing should be led directly to.When reinforcing bar falls short of, it is necessary to using welding.
At grid beams lattice point, the grid beams of both direction answer arrangement to bear reinforcing bar at an upper portion thereof, construct negative reinforcing bar and adopt With the 1/3 of its underpart longitudinal tensile reinforcing bar, and the reinforcing bar of no less than 2 a diameter of 12mm is equivalent to, to prevent uneven in load Issuable hogging moment during distribution.Negative reinforcing bar is at the lattice point of both direction grid beams intersection point, general short span direction grid Longitudinal tensile reinforcing bar below beam should be placed below long span grid beams tension reinforcement.Side bar will add additional hangs muscle, hangs muscle Whole end reactions of grid beams are passed to the compressive region of side bar by a diameter of 18~22mm；Grid beams close to beam-ends torque compared with Greatly, it is antitorque in the middle part of grid beam section in antitorque reinforcing bar, antitorque steel-bar arrangement built in 1/4~1/5 range close to beam-ends span Bar diameter is 16~18mm.
The setting encryption stirrup in the range of the deck-molding of one times of side bar end, encryption stirrup spacing are 50~75mm, and encryption is bound round The a diameter of 8mm of muscle.Increase radial steel reinforcement, a diameter of 12~16mm of radial steel reinforcement in roof boarding four corners.
Antidetonation rubber block is installed on intermediolateral column top, and installation site is 150~200mm positions below arched girder bottom elevation, in Studding antidetonation rubber block, which stays, to be set preformed hole and is passed through convenient for the main reinforcement of intermediolateral column, antidetonation rubber block include rubber, upper steel plate, spring, Lower steel plate, upper steel plate makes folded form, folding element length is 15~20mm, and the adjacent folds unit gradient is 120~140 degree, Upper steel plate thickness is 6~8mm, and upper steel plate lower surface welding spring upper end, it is 15 that lower steel plate, which makes folded form, folds element length, ~20mm, the adjacent folds unit gradient are 120~140 degree, and lower steel plate thickness is 6~8mm, and lower steel plate upper surface is welded under spring End, upper steel plate and lower steel plate unified by spring, and upper steel plate and lower steel plate distance are 40~50mm, antidetonation rubber block thickness For 100~150mm, in coming earthquake, on the one hand antidetonation rubber block buffers seismic force by rubber, and another aspect spring leads to It crosses and stretches come the seismic energy that dissipates, can also seismic force be alleviated by the folded deformation of upper steel plate and lower steel plate.
The present invention has the advantages that mechanical property is good, safe and reliable, has preferable application prospect.
