Abstract
The utility model relates to a beam-arch combined bridge of a bridge deck system without middle beams, which comprises a bridge deck, beams, girders, suspenders and arch ribs, wherein the girders and the beams form a plane frame and are supported on supporting seats of abutments, and the plane frame formed by the girders and the beams is connected with the arch ribs through the suspenders; the beams are side beams, and the middle beams are not arranged; and the bridge deck is hollow, and the hollow bridge deck is arranged on the plane frame formed by the girders and the beams in the transverse direction of the bridge. The beam-arch combined bridge has the advantages that: the traditional middle beams are eliminated and are directly replaced by the hollow bridge deck which is arranged in the transverse direction of the bridge, accordingly, web plates in the hollow bridge deck replace the original middle beams and play a transverse connecting role; with the bridge deck system without the middle beams, part of concrete and reinforced bars can be saved, and pre-stressed steel bundles can also be taken as part of tie bars, so that the consumption amount of pre-stressed reinforced bars of the tie bars can be reduced; and the bridge deck of the bridge deck system without the middle beams has high rigidity, a long maintenance period, and obvious economic benefits.
Description
Technical field:
The utility model belongs to the bridge technical field, relates to arch bridge, is specifically related to the camber combined bridge.
Background technology:
The camber combined bridge is a kind of novel bridge type of development in recent years, the characteristics of camber combined bridge are, the outside is a statically determinate structrue, inside is the high order statically-indeterminate structure, main supporting member except that arch rib, the longitudinal and cross beam of putting more energy in addition, the longitudinal and cross beam of putting more energy into is formed plane framework, get in touch up and down by suspension rod, stressed jointly.The bridge deck power transmission of traditional camber combined bridge is by way of the mode that is bridge deck → crossbeam → longeron → suspension rod → arch rib.Its deficiency is: owing to have beam structure, so increased the bridge floor height, when the bridge floor whole height does not allow to raise, under-clearance will be reduced.Have relatively high expectations and in the cross-line that bridge floor can't raise, cross a river bridge, the application of camber combined bridge is restricted in headroom.
Summary of the invention:
The purpose of this utility model is a kind of no middle cross beam bridge deck camber combined bridge of design, overcomes the deficiencies in the prior art.Numerical procedure of the present invention is: no middle cross beam bridge deck camber combined bridge, comprise bridge deck, crossbeam, longeron, suspension rod and arch rib, longeron and form plane framework with crossbeam, be supported on the bearing of abutment, longitudinal and cross beam is formed plane framework and is got in touch by suspension rod and arch rib, bridge deck place longeron and form on the plane framework with crossbeam, it is characterized in that described crossbeam is the limit crossbeam, do not establish middle cross beam, described bridge deck are hollowcore slabs, the hollow bridge deck direction across bridge is placed, and places longeron and forms on the plane framework with crossbeam, and described arch rib is the steel pipe concrete arch rib.
Compared with prior art, the beneficial effects of the utility model are;
1. work simplification, with traditional middle cross beam cancellation, directly the hollowcore slab of placing with direction across bridge replaces, and the web in the hollowcore slab had both substituted original middle cross beam like this, had played the effect of lateral ties again, and had reduced the bridge deck absolute altitude to greatest extent;
2. saving material, no crossbeam bridge deck are except that itself can save part concrete and reinforcing bar, and the prestressed strand in it also can serve as the part tie-rod, has reduced tie-rod prestressed reinforcement consumption; The bridge floor rigidity of not having the crossbeam bridge deck in addition is big, and maintenance period is long, has tangible economic benefit;
Description of drawings:
The utility model has accompanying drawing 4 width of cloth, wherein
Accompanying drawing 1 is a no middle cross beam bridge deck camber combined bridge elevational schematic view of the present utility model,
Accompanying drawing 2 is no middle cross beam bridge deck camber combined bridge floor map of the present utility model,
Accompanying drawing 3 is no middle cross beam bridge deck camber combined bridge half range Bridge Sections schematic diagrames of the present utility model,
Accompanying drawing 4 is that the B-B of accompanying drawing 3 is to generalized section.
In the accompanying drawing, 1, arch rib, 2, suspension rod, 3, longeron, 4, crossbeam; 5, bridge deck, 6, stull, 7, bearing, 8, anticollision barrier, 9, Hanger Anchor head protection cover; 10, abut, 11, default concrete spouting hole, 12, default concrete spouting hole, 13, abutment, 14, pile foundation.
The specific embodiment:
With embodiment the utility model is described further with reference to the accompanying drawings below:
The bridge center line is a plane and straight line, 38 meters of overall length of bridge; The bridge longitudinal gradient is unidirectional 1%.The bridge standard cross-section is: 1.395 meters (arch ring+railing+marginal strip)+3 * 3.5 meters (roadway)+1.595 meter (arch ring+railing+marginal strip)+0.02 meter (constuction joint)+1.595 meter (arch ring+railing+marginal strip)+3 * 3.5 meters (roadway)+1.395 meter (arch ring+railing+marginal strip)=27 meters.Bridge construction is a hole lower support type Steel Pipe Concrete Tied-arch Bridge, and its arch axis line is a second-degree parabola, rise 9m, ratio of rise to span 1/4.Full-bridge is divided into and is the two identical width of cloth of bridge deck structure; only establish longeron 3 and limit crossbeam 4; do not establish middle cross beam; longeron 3 and limit crossbeam 4 are formed plane framework; be supported on the bearing 7 of abutment 13; abutment is supported on the pile foundation 14; longeron 3 and limit crossbeam 4 are formed plane framework and are got in touch by suspension rod 2 and arch rib 1; suspension rod 2 is chill casting anchor formula boom systems; suspension rod 2 is provided with Hanger Anchor head protection cover 9 with arch rib 1 junction; bridge deck 5 direction across bridge place longeron 3 and form on the plane framework with crossbeam 4, and bridge floor is made up of cast-in-situ concrete longeron 3 and cast-in-place monolithic bridge floor hollowcore slab 5.Cast-in-place bridge floor thickness of slab 80cm, two ends place on the longeron, the thick reinforced concrete floor of the bridge deck 5 cast-in-place 6cm in top, upper berth 8cm asphalt concrete pavement layer.Arch rib 1 is the steel pipe concrete arch rib, and every width of cloth is laterally established two, totally 4 of full-bridges.It is 600mm that arch rib 1 is diameter, and wall thickness is the steel pipe of 16mm, placing C55 slightly expanded concrete in the steel pipe.Default concrete spouting hole 11,12 on the steel pipe of steel pipe concrete arch rib.1 of two arch rib of every width of cloth bridge floor are established twice in-line stull 6, adopt diameter 500mm, the steel pipe of wall thickness 14mm.Each arch rib 1 is divided into eight suspension rods 2, is 4 meters along bridge to suspension rod 2 spacings.
