Abstract
The invention provides a prestressed concrete beam and slab assembly with the upper portion provided with flexural reinforcing steel bars and a frame structure. The flexural reinforcing steel bars are additionally arranged on the upper portion of the long-span concrete beam and slab assembly and are connected with a column, so that a long-span slab arris serves as a frame beam, and therefore the frame structure is formed.
Description
Affiliated technical field: building material field
Background technology
Large-span prestressed concrete beam slab is for frame construction, there is no at present the structural system matching, and cannot use, intend Vierendeel girder cost also larger, especially the vertical reinforcing bar of transverse frame is not only slightly not only long but also close, and support shuttering loaded down with trivial details valency in high-altitude is high, and considerable expert queries and to think unreliablely, and must be that 5 meters, 7.5 meters, 9.9 meters fixed frames are apart from not conforming to corresponding technological requirement to the sheet-pile net of 2.4 meters wide.
Summary of the invention
The large-span prestressed concrete beam slab and the frame structure system thereof that the invention provides a kind of top band bending steel muscle have solved above-mentioned drawback.The large-span prestressed concrete beam slab of top band bending steel muscle comprises T plate, single T beam slab, a trough slab, it is characterized in that plate top is especially provided with bending steel muscle in rib top.
Further top band bending steel muscle large-span prestressed concrete beam slab, is characterized in that the bending steel muscle amount two ends on plate top are many, centre few.
Further the large-span prestressed concrete beam slab of top band bending steel muscle, is characterized in that in concrete, joint bar being set up and down along bending steel muscle.
Further the large-span prestressed concrete beam slab of top band bending steel muscle, is characterized in that position, termination is provided with dowel.
Further a kind of large-span prestressed concrete beam slab frame structure system comprises: the Large Span Prestressed Beam plate of frame column, frame rails, top band bending steel muscle, it is characterized in that: on concrete slab, especially rib top arranges bending steel muscle, be connected with reinforcing bar on post, slugging on bracket on embedded part and post under plate end, thus a kind of large-span prestressed concrete beam slab frame construction formed.
Further the large-span prestressed concrete beam slab frame structure system of top bending steel muscle, is characterized in that bottom, rib two ends has iron embedded part to be connected with steel in frame rails or embedded part.
Further large-span prestressed concrete beam slab frame structure system, it is characterized in that the trough slab without the edge of a wing, rectangular beam, hollowcore slab, box beam rib is connected with post reinforcing bar or rib is strengthened being connected with post reinforcing bar or 2 ribs that face mutually being combined, the middle cementation of fissures, top bending steel muscle is connected with post reinforcing bar together, the T plate that has the edge of a wing, single T plate, many T box beam, there is the bridge board on the edge of a wing to remove the edge of a wing rib is corresponding with post, reinforcing bar connects, also 2 ribs that remove the corresponding edge of a wing that face mutually can be connected together, the middle cementation of fissures, both sides of the chest top bending steel muscle rib is connected with post together, single rib, two ribs are connected with post reinforcing bar after can also strengthening.Under beam slab termination, on embedded part and bracket, the such beam slab rib of slugging has played framework beam action
Further utilize the shearing that under beam slab termination, on embedded part and bracket, slugging provides, be less than or equal to the pulling force that on top bending steel muscle and post, reinforcing bar is connected to form, according to the high restraining moment that forms of beam slab rib, this becomes hinged frame into framework.
Accompanying drawing explanation:
Fig. 1 is large-span prestressed T plate frame structure system schematic diagram, and Fig. 1-1 is front elevation view, and Fig. 1-2 is side elevational view, and Fig. 2 is large-span prestressed trough slab frame structure system schematic diagram, and Fig. 2-1 is front elevation view, and Fig. 2-2 are side elevational view.
