Description
Technical field
The invention belongs to the building engineering structure technical field, be specifically related to a kind of virtual beam for the large-span prestressed concrete beam slab frame construction.
Background technology
Large-span prestressed concrete beam slab [wherein T plate, groove type plate and (hereinafter to be referred as T-shaped plate) and the hollowcore slabs (hereinafter to be referred as the SP plate) such as single T plate, many T box-girder] belongs to high-strength concrete thin-wall member (espespecially the former), its maximum advantage is: span is large, can build the Large Column Spacing longspan structure; Rise low (0.45 ~ 1.085m is about roof truss structure height＜roof truss height and adds the roofing plate hight〉1/4 ~ 1/3) can significantly reduce depth of building, reaches the effect of saving metal material and energy; Good stability does not need additional lateral support; The member wide coverage, installation effectiveness is high, becomes one of building roof structure form that replaces the tool advantage of traditional roof system.
It must be noted that, the most floor plate structural element that are used for roof panel and non-frame construction of present T-shaped plate and SP plate, and be obstructed for the application of the DESIGN TREND OF MODERN INDUSTRIAL ARCHITECTURE that has a large capacity and a wide range, public building, commercial building middle frame structure, thereby the large-scale popularization that has limited to a great extent this large span sheet material is used.It is used the reason of being obstructed and mainly contains two: one in frame construction, not yet find the structural calculation model and the corresponding design structure method that are complementary with it.It is investigated in the equal content of not mentioned this respect of the logical figure of the local mark of the prefabricated and prestressed concrete handbook of the U.S. and China, and at " Code for design of concrete structures " and " seismic design provision in building code " of China also without this related content.But pertinent literature has a clause regulation: do not allow to adopt the hinged frame structure in the earthquake protection area.The 2nd, the draft frame structure small draft frame structure is to have provided several usages of doing, limited many practices that can realize virtual beam such as 1, can prefabricated virtual beam, and its both sides exposed steel bar is connected again pouring concrete with transverse strands stud or net sheet on the prestressing force beam slab of post both sides, its longitudinal reinforcement that exposes is connected with the pillar exposed steel bar, again pouring concrete; Or expose that reinforcing bar is connected in the hole on longitudinal reinforcement and the pillar, pouring concrete again; 2, can also replace reinforced concrete beam with girder steel or steel concrete beam.
Summary of the invention
The object of the invention is to the defective for above-mentioned prior art, a kind of virtual beam for the large-span prestressed concrete beam slab frame construction is provided.
Technical scheme of the present invention is as follows: a kind of virtual beam for the large-span prestressed concrete beam slab frame construction, comprise frame column and frame rails, at 2 large span prestressed concrete T plates near the frame column both sides, contain the hollow single T plate of large span prestressed concrete at interior large span prestressed concrete list T beam slab, the large span prestressed concrete hollowcore slab that comprises the SP plate, the large span prestressed concrete trough slab, any one that comprises the large span prestressed concrete rectangular beam of hollow rectangle beam slab and many T of large span prestressed concrete box-shaped beam slab is provided with horizontal handling reinforcement, virtual beam is positioned in the middle of two prestressing force beam slabs of frame column both sides and in the middle of frame column and the other end frame column, and the longitudinal reinforcement of virtual beam is connected with end frame trestle reinforcing bar and is connected with transverse strands stud or the net sheet of connection box trestle both sides prestress concrete girder slab face below longitudinal reinforcement top.
Further, in the virtual beam stirrup is arranged, stirrup is connected the longitudinal rib of connection box trestle in the virtual beam with horizontal handling reinforcement or net sheet reinforcing bar, be provided with the concrete whole casting layer on it again.
Further, little plan Vierendeel girder reinforcing bar is nonprestressed reinforcement.
Further, a side of 2 large span prestressed concrete list T beam slabs of virtual beam both sides, T plate, many T box-shaped beam slab has been respectively the edge of a wing; Without the edge of a wing or without the part edge of a wing.
Further, at the large span prestressed concrete T plate near the frame column both sides, single T beam slab, the hollowcore slab that comprises the SP plate, large-span prestressed trough slab, the large span prestressed concrete rectangular beam that comprises the hollow rectangle beam, many T of large span prestressed concrete box-shaped beam slab side pars intermedia has hole, set up the vertical reinforcing bar of transverse strands at hole, at hole and handling reinforcement position virtual beam is set, it is positioned in the middle of two prestressing force beam slabs of frame column both sides and in the middle of frame column and the other end frame column, and the longitudinal reinforcement of virtual beam is connected with end frame trestle reinforcing bar and is connected with transverse strands stud or the net sheet of connection box trestle both sides prestressed concrete beam hole below longitudinal reinforcement top; And connect with stirrup, the concrete cast-in-situ layer is arranged at virtual beam top.
Further, virtual beam is nonprestressed reinforcement concrete beam or non-prestressed girder steel or non-prestressed steel concrete beam.
Further, laterally its riveting of handling reinforcement is pluged with molten metal length and should or be passed through 4 ribs of 2 T plates in frame column post both sides greater than cantilever span.
Beneficial effect of the present invention is as follows: the virtual beam that is used for the large-span prestressed concrete beam slab frame construction, the weight of little plan Vierendeel girder and upper load thereof under vertical uniform load q since prestressed concrete plate and non-prestressed plan Vierendeel girder under vertical uniform load q, be out of shape the more large and complete section of difference and pass on the prestressed concrete plate of both sides, thereby both become the rod member without load, can dispose by the minimal construction arrangement of reinforcement, become again without the moment of flexure rod member, under horizontal loading or geological process, draw or the rod member of pressure for mainly bearing.The edge of a wing that when construction, need not cut away T-shaped plate, the cross section of beam reduces to save cost, and construction is simple, efficient, can several different methods make virtual beam again.
