Abstract

Flexual reinforcement is added to connect with frame column on large-span concrete beam plate top, so that large span rib of slab be made to play frame beam action into frame structure.

Description

A kind of large-span prestressed concrete beam slab frame structure system
Technical field
Building engineering field.
Background technique
Large-span prestressed concrete beam slab is used for frame structure, there is no matching structural system at present, and can not It uses, quasi- Vierendeel girder cost is also larger, and especially lateral bearing rod is too many, too long, cost is too big, and high-altitude support shuttering is numerous It is trivial, and considerable expert query think it is unreliable, and must be 5 meters to 2.4 meters wide of sheet-pile net, 7.5 meters, 9.9 meters it is solid Determine frame away from many workshop techniques require be not consistent.
Summary of the invention
The present invention provides a kind of large-span prestressed concrete beam slab frame structure to solve above-mentioned drawback.
Large-span prestressed concrete beam slab frame structure, comprising: frame column, frame rails, large-span prestressed coagulation Native beam slab, including T plate, list T beam slab, trough plate, swallow shape plate, square cross girders, bridge plate, more T box beams and cored slab, feature It is: beam slab rib is correspondingly placed on column front baffle stringer, increases bending steel on concrete beam plate top or rib top Muscle is connect with reinforcing bar on frame column, and beam slab rib both ends bottom has iron embedded part to be welded with frame rails steel embedded part, to be formed A kind of large-span prestressed concrete beam slab frame structure system.
Further the flute profile rib of slab placement corresponding with frame column on no edge of a wing, upper part flexual reinforcement and reinforcing bar on frame column Connection merges 2 adjacent ribs, the intermediate cementation of fissures, and corresponding with frame column to place, top is by reinforcing bar on curved frame column It is connect with column reinforcing bar；It places single rib of the T plate for having the edge of a wing is corresponding with frame column, flexual reinforcement and frame column upper prop on beam slab Reinforcing bar connection, or 2 adjacent ribs for removing the corresponding edge of a wing are connected together, the intermediate cementation of fissures is corresponding with frame column to place, and two Plate top or both sides of the chest top flexual reinforcement are formed by connecting with steel on frame column together.
Flexual reinforcement is equipped with joint bar in concrete to the lower part in further large-span prestressed concrete beam slab, and end is equipped with Dowel.
Flexual reinforcement amount both ends are how intermediate few on further large-span prestressed concrete beam slab.
The T plate that top described further is equipped with flexual reinforcement can remove a side wing edge, can also move edge, plate with rib Width is basically unchanged, and effective area is basically unchanged, and forms " F " plate.
The shearing further provided using embedded part under beam slab rib and the slugging in frame rails, is less than or equal on beam slab Flexual reinforcement connect the pulling force to be formed with reinforcing bar on column, restraining moment is formed according to rib of slab height, so that forming steel connects grid beam knot Structure.
The large-span prestressed concrete beam slab of large-span prestressed concrete beam slab described further in flexual reinforcement Joint bar is set into upper and lower concrete along flexual reinforcement, dowel is arranged in end position.
Four, Detailed description of the invention:
Fig. 1-1 is Large Span Prestressed Beam plate framework structural system schematic diagram front elevation view
Fig. 1-2 is Large Span Prestressed Beam plate framework structural system schematic diagram side elevational view
Fig. 2-1 is prestressing force trough plate frame structure system schematic diagram front elevation view
Fig. 2-2 is prestressing force trough plate frame structure system schematic diagram side elevational view
1 is frame column；2 be frame rails.3 be the T plate for removing the top increase flexual reinforcement of a side wing edge；4 be plate Upper flexual reinforcement；5 increase the trough plate of flexual reinforcement for top.
Five, specific embodiment:
There is flange plate by taking T plate as an example, as Figure 1-1: frame column 1 and frame rails 2 are built with conventional method, two The T plate 3 for removing the corresponding edge of a wing is arranged in the frame rails of T plate both ends frame column 1, plate top flexual reinforcement 4 and frame Steel welding, plate lower part built-in fitting on angle steel, with frame column 1 can be arranged at 3 end position of T plate in reinforcing bar connection on trestle 1 It is connect with the embedded part in frame rails 2, does again secondary pour layer above.This scheme merely adds flexual reinforcement and lighter in weight Joint bar, dowel, tip angle steel, cost is very low, eliminates the enormous expenditure of the high-altitude formwork supporting plate of quasi- Vierendeel girder and not only thick but also long Close lateral cableway again (wears 2 × mono- side wing edge that 4 ribs of T plate are not passed through for 2 × 2.4 meters wide T plates- It is 0.5 meter=3.8 meters long), and check of drawings, design specialist, do not approve mostly think that quasi- frame is not Vierendeel girder but to further The drawbacks of test system.
Without flange plate by taking trough plate as an example: as shown in Fig. 2-1:
1, frame rails 2 on frame column 1 and column are built with conventional method, reserves embedded part in frame rails 2；
2, the placement corresponding with frame column 1 of trough plate 5 top with flexual reinforcement 4, both ends flexual reinforcement 4 and end frame Reinforcing bar connects on trestle 1, and 5 end lower part embedded part of trough plate is formed by connecting with the embedded part in frame rails 2.
