Technical field
The present invention relates to science of bridge building fields, and in particular to a kind of damaged prosthetic device at Bridge Beam bottom.
Background technology
With the fast development of China's traffic, bridge, elevated bridge, high-speed rail bridge etc. are rapidly developed, for bridge
For, beam bottom is cracky position, once breakage occurs, it, can shadow when can reduce the performance, especially badly broken of bridge
Internal reinforcing bar is rung, steel bar corrosion, the entire stress performance of beam body is then caused significantly to be decayed, bridge life is influenced and makes
Use safety.
Breakage for Bridge Beam bottom is often repaired using grouting, and this repair mode is relatively single, and cannot be effectively right
Bridge Beam bottom carries out partition protection, and after the completion of reparation, Bridge Beam bottom is still easy because the reasons such as water inlet, chip off-falling continue to occur to break
Damage.

Specific implementation mode：The structure that the present invention limits specifically is explained below for Figure of description content
Explanation.
The present invention provides a kind of damaged prosthetic device of 1 beam bottom of bridge, which is used for the breakage of 1 beam bottom of bridge
Place, it is characterised in that：A layer of adhesive 2 is smeared in the breakage of 1 beam bottom of bridge, cement mortar is set in described adhesive 2
The thickness of layer 3, the cement sand bed 3 is not less than 5cm, and waterproof layer 4 and geomembrane are set gradually on the cement sand bed 3
5, carbon cloth 6 is set on the geomembrane 5, and the first L-shaped fixed plate 7 and the 2nd L is respectively set in 1 beam bottom both ends of the bridge
First limb of shape fixed plate 8, first L-shaped fixed plate, 7 and second L-shaped fixed plate 8 is fixed on the beam bottom by bolt 9
On, the second limb of first L-shaped fixed plate, 7 and second L-shaped fixed plate 8 is vertical with the beam bottom, the carbon cloth 6 and
Second limb of one L-shaped fixed plate 7 connects, and forms anchored end 10, the second limb company of the carbon cloth 6 and the second L-shaped fixed plate 8
It connects, forms stretching end 11.
Preferably, described adhesive 2 is polyurethane binder.
Preferably, the waterproof layer 4 is high-polymer modified pitch.
In above-mentioned fixed form, the beam of the longitudinal direction and bridge 1 of first L-shaped fixed plate, 7 and second L-shaped fixed plate 8
Width is equal, i.e., first L-shaped fixed plate, 7 and second L-shaped fixed plate 8 is arranged on the length direction of bridge 1 in Fig. 1.Institute
The length of adhesive 2, cement sand bed 3, waterproof layer 4, geomembrane 5, carbon cloth 6 is stated equal to 7 and of the first L-shaped fixed plate
The distance between second L-shaped fixed plate 8, described adhesive 2, cement sand bed 3, waterproof layer 4, geomembrane 5 width with it is described
The deck-siding of bridge 1 is equal；
With reference to figure 2 it is found that in the direction of the width, the width of carbon cloth 6 is slightly larger than 1 deck-siding of bridge, is more than the carbon of 1 deck-siding of bridge
Fiber cloth 6 is folded upward on the both sides of 1 width direction of bridge and is fixed in 1 beam body of bridge.
