Abstract

The utility model discloses a reinforced concrete arch bridge arch rib and a mounting support seat thereof. The reinforced concrete arch bridge arch rib and the mounting support seat thereof can be used for manufacturing and mounting of a common reinforced concrete arch bridge arch rib and a reinforced concrete tie rod arch bridge arch rib, improve the stability of an arch rib support in the mounting process and after mounting in place of the arch rib, and guarantee the safety of mounting of the arch rib. The arch rib comprises an arch rib body, and a thrust conversion support seat is arranged at the corresponding mounting position of the arch rib body and the arch rib support. A support seat body of the mounting support seat is an H-shaped body, the upper end face of the support seat body is a horizontal plane, and the support seat body is welded on the top of the arch rib support and contacts with a bottom plate of the thrust conversion support seat in a horizontal mode. The interaction force between the arch rib and the arch rib support in the horizontal direction is removed, the stability of mounting of the arch rib is guaranteed, the safety of construction is greatly improved, relevant construction risks are avoided, and meanwhile the construction quality of engineering is improved.

Description

A kind of reinforced concrete arch bridge arch rib and erection support thereof
Technical field
The utility model relates to the arch rib of reinforced concrete arch bridge, particularly a kind of reinforced concrete arch bridge arch rib and erection support thereof, can be used for making and the installation of ordinary reinforced concrete arch rib and steel concrete bowstring arch bridge arch rib, improve in the arch rib installation process and the stability of arch rib support after installation in position, guarantee the safety that arch rib is installed.
Background technology
Ordinary reinforced concrete arch bridge and steel concrete bowstring arch bridge all belong to reinforced concrete arch bridge.At present, in the installation process of reinforced concrete arch bridge arch rib and steel concrete bowstring arch bridge arch rib, the abutting joint of arch rib and arch rib support is a construction technology difficult problem, there is no special processing method, generally arch rib is not processed and directly is placed on the arch rib support.This form of construction work, because arc rib alignment is arch, the interaction force of arch rib and arch rib support is along the normal direction of arch rib camber line, and this has just caused the interaction force that has horizontal direction between arch rib and arch rib support.When arch rib is installed, its contact surface with the arch rib support is little and the arch rib support is existed to the thrust of along continuous straight runs, is unfavorable for the stability of arch rib support, has potential safety hazard and great construction risk.Because exist very high risk, guarantee that arch rib is installed stable, just higher to the steadiness requirement of arch rib support.When the arch rib Rig up error, there is the danger of collapsing in the arch rib support, and this problem affects construction speed and the construction quality of reinforced concrete arch bridge always.Reinforced concrete arch bridge need to improve the structure of arch rib, reduces the installation risk of ordinary reinforced concrete arch bridge and steel concrete bowstring arch bridge arch rib.
Summary of the invention
The purpose of this utility model is to provide a kind of reinforced concrete arch bridge arch rib and erection support thereof.Overcome the defect of prior art, solve traditional arch rib the bad problem of stability is installed, improve working security and workmanship.
The utility model is achieved in that
A kind of reinforced concrete arch bridge arch rib, comprise the arch rib body, is provided with thrust conversion bearing on the position of arch rib body and the corresponding installation of arch rib support.
A seat body of erection support is the work body, and its upper surface is horizontal plane, and the top that a seat body is welded on the arch rib support contacts with the floor level of thrust conversion bearing.
The beneficial effects of the utility model are as follows.Application the utility model has significantly improved the stability that the reinforced concrete arch bridge arch rib is installed.By fixing embedded bar on the arch rib body, and then weld base plate on the basis of embedded bar, while making in the future the arch rib installation in position, the installation site at two ends is horizontal level, and the contact surface of arch rib and arch rib support is converted into to horizontal plane.Like this, arch rib to the active force of arch rib support perpendicular to horizontal contact surface, active force straight down, do not exist the thrust on arch rib support level direction, eliminate the interaction force on horizontal direction between arch rib and arch rib support, guaranteed the stability that arch rib is installed, greatly improved the safety of construction, avoid corresponding construction risk, improved the construction quality of engineering simultaneously.Because the utility model is convenient to the installation of arch rib, can also the reduction of erection time, improve project benefit.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model arch rib and erection support.
Fig. 2 is for being used the stressed effect figure after arch rib of the present utility model is installed.
The specific embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail, referring to Fig. 1.A kind of reinforced concrete arch bridge arch rib, comprise arch rib body 3, is provided with thrust conversion bearing on the position of arch rib body 3 and the corresponding installation of arch rib support 5.Thrust conversion bearing comprises embedded bar 1 and base plate 2, and the lower surface of base plate 2 is horizontal planes, and embedded bar 1 is fixed in arch rib body 3, base plate 2 is welded on to the lower end of embedded bar 1.Base plate 2 is circular, square or polygon, and its thickness setting is between 10mm-100mm; Base plate 2 is exactly the angle of arch body 3 with the angle of arch rib body 3.The diameter of embedded bar 1 is set between 20mm-60mm.According to the sum of its diameter design embedded bar 1, diameter is larger, and the radical of its embedded bar 1 is fewer.
For a kind of erection support of reinforced concrete arch bridge arch rib, its seat body 4 is work bodies, and its upper surface is horizontal plane, and the top that a seat body 4 is welded on to arch rib support 5 contacts with base plate 2 levels of thrust conversion bearing.The external shape of seat body 4 top plate bodys can be identical or different with base plate 2, and its diameter or area can be identical with base plate 2 or be greater than base plate 2.
Embedded bar 1 bulk strength should meet formula: SNf σ c > kF;
In formula:
The single cross-sectional area of S-embedded bar 1;
Total radical of N-embedded bar 1;
The single standard shear strength value of f σ c-embedded bar 1;
K-thrust conversion bearing safety factor, k >=5;
F-embedded bar 1 contacts the mid-point computation horizontal thrust with arch rib body 3.
Embedded bar 1 compressive strength should meet formula: SNf σ bc > kG;
In formula:
The single cross-sectional area of S-embedded bar 1;
Total radical of N-embedded bar 1;
F σ bc-embedded bar 1 single compression strength value;
K-thrust conversion bearing safety factor, k >=5;
The gravity of G-arch rib body 3.
Referring to Fig. 2, when the arch rib of reinforced concrete arch bridge is installed, as long as the base plate 2 of the thrust at arch rib body 3 two ends conversion bearing is alignd to placement with a seat body 4 of the erection support at arch rib support 5 tops.The active force straight up that in Fig. 2, P representative 4 pairs of base plates of seat body 2 produce; G represents the gravity of arch rib body 3.When base plate 2, with after seat body 4 aligns, the thrust that 3 pairs of arch rib supports 5 of arch rib body produce has just become active force straight down, has guaranteed the stability of arch rib, has reduced construction risk.
