Abstract

A bending steel bar is added to the upper portion of a large-span concrete beam board and connected with a column, and therefore a large-span slab arris serves as a frame beam to form a frame structure.

Description

A kind of large-span prestressed concrete beam slab frame structure system
One, affiliated technical field: building engineering field
Two, 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 transverse strands stud is too many, oversize, cost is too large, and high-altitude support shuttering is loaded down with trivial details, 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 many factory building technological requirements to the sheet-pile net of 2.4 meters wide.
Three, summary of the invention
The invention provides a kind of large-span prestressed concrete beam slab frame construction to solve above-mentioned drawback.
Large-span prestressed concrete beam slab frame construction, comprise: frame column, bracket on frame rails or post, large-span prestressed concrete beam slab, comprise T plate, single T beam slab, trough slab, swallow shape plate, square cross girders, bridge board, many T box beam and hollowcore slab, it is characterized in that: beam slab rib correspondence is placed on post on bracket or on post front longitudinal, on concrete beam plate top, especially rib top increases bending steel muscle, be connected with reinforcing bar on post, beam slab rib two ends bottoms has on iron embedded part and frame rails or frame column bracket steel or embedded part weld, thereby form a kind of large-span prestressed concrete beam slab frame structure system.
Further the placement corresponding to post of the flute profile rib of slab without the edge of a wing, its top bending steel muscle and post
Upper reinforcing bar connects or rib is strengthened to upper back bending steel muscle and is connected with post reinforcing bar or 2 ribs that face are mutually combined, or combines after strengthening, the middle cementation of fissures, and placement corresponding to post, top bending steel muscle is connected with post reinforcing bar; The single rib placement corresponding to post that has the T plate on the edge of a wing, on beam slab, bending steel muscle is connected with post reinforcing bar, also 2 ribs that remove the corresponding edge of a wing that face mutually can be connected together, the middle cementation of fissures, placement corresponding to post, two plate tops especially both sides of the chest top bending steel muscle be connected with steel on post together or both sides of the chest or one of them rib are strengthened after in the middle of the cementation of fissures, two plate tops especially both sides of the chest top bending steel muscle together with post on steel be formed by connecting.
Further in large-span prestressed concrete beam slab, bending steel muscle is provided with joint bar in the concrete of bottom, and end is provided with dowel.
Further on large-span prestressed concrete beam slab, bending steel muscle amount two ends are how middle few.
The T plate that top is further provided with bending steel muscle can remove a side wing edge, also can move limit portion by rib, and plate is wide substantially constant, and effective area is substantially constant, forms " F " plate.
Further utilize under beam slab rib on embedded part and beam or shearing that the slugging on bracket beam provides, be less than or equal to the pulling force that on beam slab, on bending steel muscle and post, reinforcing bar is connected to form, according to rib of slab height, form restraining moment, thereby form steel, connect frame girder construction.
Further described large-span prestressed concrete beam slab arranges joint bar in concrete at the large-span prestressed concrete beam slab of bending steel muscle up and down along bending steel muscle, and position, termination arranges dowel.
Four, accompanying drawing explanation:
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 slab frame structure system schematic diagram front elevation view
Fig. 2-2 are prestressing force trough slab frame structure system schematic diagram side elevational view
1 is frame column; 2 is frame rails.3 increase the T plate of bending steel muscle for removing the top of a side wing edge; ; 4 is bending steel muscle on plate;
Five, the specific embodiment:
Take T plate as example, as shown in Figure 1: by conventional method, build bracket beam 2 on frame column 1 and post, two T plates 3 that remove the corresponding edge of a wing are arranged on the bracket of T plate end frame trestle 1, plate top bending steel muscle 4 is connected with the reinforcing bar on post 1, can angle steel be set at T plate 3 positions, termination, with steel welding on post 1, plate bottom built-in fitting is connected with the embedded part on bracket 2, does secondary above again and waters layer.This scheme, joint bar, dowel, termination angle steel that bending steel muscle and weight are lighter have only been increased, cost is very low, removed the enormous expenditure of the high-altitude formwork supporting plate of intending Vierendeel girder from and slightly grown not only not only but also close horizontal handling reinforcement, (4 ribs wearing T plate are that 0.5 meter=3.8 meters of 2 * mono-side wing edges of 2 * 2.4 meters wide T plates-do not pass are long), and check of drawings, design specialist, thinking of mostly not approving to intend framework be not Vierendeel girder but treat the drawback of further test system
Take trough slab as example: as shown in Figure 2:
1, by conventional method, build bracket 2 on frame column 1 and post, reserved embedded part on bracket 2
2, the placement corresponding to post 1 of the trough slab 3 of top band bending steel muscle 4, two ends bending steel muscle 4 is connected with reinforcing bar in two newel posts 1, the embedded part on trough slab 3 bottom, termination embedded parts and bracket 2 is formed by connecting.
