Defect and degeneration, bridge floor and arch ring there is apparent crack and seminess, reinforced.Traditional reinforcing side
Method, generally use set arch reinforce arch ring, and operating process is complicated, and cost is high, long in time limit, is difficult to meet vehicle pass-through in a short time
It is required that.
Invention content
The purpose of this utility model is that for the disease of stone arch bridge arch ring and damaging oof bridge surface, a kind of new reinforcing side is provided
Formula reduces reinforcement cost under the premise of improving the service life of stone arch bridge, shortens construction period.
The utility model provides a kind of stone arch bridge strengthening structure, and technical solution is as follows：
A kind of stone arch bridge strengthening structure, it is characterised in that：Including multiple bar shaped support bases, two Bailey beams, more transverse directions
Distribution beam, more longitudinal distribution beams and floorings, direction across bridge is being fixed on each bridge pier of stone arch bridge just to multiple support bases respectively
Top, two Bailey beams are to reinforce chord member Bailey beam, and two Bailey beams are respectively along bridge to being fixed at the top of the support base both ends, institute
It states the equal direction across bridge setting of more transverse distribution beams and across on two Bailey beam lower booms, described more longitudinal distribution beams is along bridge
To being arranged and being fixed on transverse distribution beam, the floorings are laid in longitudinal distribution beam.
The utility model reinforces arch using original stone arch pier column as load-bearing basis, using the assembling structure of shellfish thunder shaped steel
Load is loaded the base-supporting structure on Bailey beam lower boom by longitudinal distribution beam, transverse distribution beam, makes shellfish by circle and bridge floor
Lei Liang had both been load-carrying members, but also as the guardrail of bridge both sides, had simple in structure, low cost, the quick and convenient equal spies of construction
Point, and securely, strength and stiffness can meet vehicle pass-through requirement.

Specific implementation mode
As shown in Figure 1, Figure 2, Figure 3 shows, stone arch bridge strengthening structure provided by the utility model, including multiple bar shaped support bases
1, two Bailey beams 2, more transverse distribution beams 3, more longitudinal distribution beams 4 and floorings 5, multiple support bases 1 distinguish cross-bridges
To being fixed on right over 6 each bridge pier of stone arch bridge, the Bailey beam 2 reinforces chord member structure, two Bailey beams point using single layer three pieces
Not along bridge to the top being fixed on close to 1 both ends of support base；The 3 equal direction across bridge of more transverse distribution beams setting and across
On the lower boom 21 of two Bailey beams 2,3 end of transverse distribution beam sets diagonal brace 7 and the top boom 22 of Bailey beam 2 welds；Described more
For longitudinal distribution beam 4 along bridge to being arranged and being fixed on transverse distribution beam 3, the floorings 5 are laid on longitudinal distribution beam 4
On.
As shown in Figure 4, Figure 5,1 cross section of the support base is rectangle.Support base is cast in using armored concrete
Right over stone arch bridge bridge pier, each support base both ends set two vertically arranged gag lever posts 8 respectively, and 8 ends are pre-buried under gag lever post
In support base.
As shown in Figure 1, the lower boom 21 of the Bailey beam is located between two gag lever posts 8 of support base end, two limits
The lateral compression bar 9 of welding one between 8 upper end of bar, the transverse direction compression bar 9 are pressed on 21 top of Bailey beam lower boom.
As shown in Figure 1, the Bailey beam is single layer three pieces reinforced structure, Bailey beam top boom 22 passes through diagonal brace 7 and cross
It is fixedly connected to 4 end of distribution beam, it is ensured that the overall stability of Bailey beam.The utility model is when it is implemented, according to being reinforced
Stone arch bridge length, every Bailey beam can be used multiple Bailey beam sections and is formed by connecting.
As shown in Figure 6, Figure 7, transverse distribution beam 3 is fixed with Bailey beam lower boom 21 by U-bolts 10, described to ride
Open Side Down for bolt 10, transverse distribution beam 3 is stuck in U-bolts opening, 10 lower end of U-bolts is located at Bailey beam lower edge
The lower section of bar 21, and intert one piece of backing plate 11, backing plate 11 is fixed under Bailey beam lower boom 21 by two nuts 12
Side, it is fixed between transverse distribution beam and Bailey beam lower boom to make.
The utility model is when it is implemented, work steel can be used in transverse distribution beam；Longitudinal distribution beam uses channel steel, and Open Side Down
Arrangement, adjacent longitudinal direction distribution beam center spacing is 22cm.
As shown in Fig. 1, Fig. 8, floorings 5 are laid in longitudinal distribution beam 4.Floorings 5 use 10mm steel plates, floorings
Upper direction across bridge welds a reinforcing bar 13 every 1m.The floorings of the utility model will be carried by longitudinal distribution beam, transverse distribution beam
Lotus loads on the lower boom of Bailey beam, so this structure is base-supporting structure, after Bailey beam is at the same time as stone arch bridge strengthening
Bridge floor both sides protective device, guards making can be saved, highlight that the utility model installation is simple, and short construction period is at low cost
The features such as, be conducive to accelerate construction progress.
As shown in Figure 2 and Figure 3, in order to preferably ensure the drop-over of the existing road of bridge floor and bridge both ends after reinforcing, in stone arch
Bridge both ends are respectively along bridge to one English truss 14 of setting, between 14 direction across bridge width of English truss is not less than between two Bailey beams
Away from, highly be not higher than reinforce after floorings height.
