At present, the water-proof sealing rubber strip of existing bridge extension joint is single " C " font structure mostly, draw bad must replacing it afterwards once expand with heat and contract with cold, application life is short, changing each time construction is very aspect not, and change required direct cost be initial install more than 5 times, waste so very greatly, cost is very high.
Utility model content
For defect of the prior art, the purpose of this utility model is to provide a kind of bridge expansion joint installation.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
The utility model bridge expansion joint installation, comprise pre-buried dowel, square dowel, horizontal bar, rear pouring concrete and bridge main body, between described bridge main body beam body, be provided with trough with straight angle, square dowel is transversely arranged being located at above trough with straight angle at a certain distance, horizontal bar interts in square dowel inner side, the described pre-buried dowel Integral bending structure that meets at right angles, be placed on above a part of horizontal bar, two ends are placed in bridge main body inside, described rear pouring concrete is cast in above trough with straight angle, it is characterized in that: fixing muscle has been tied up in described square dowel inside, fixing muscle one end is bent into right angle and is inserted between horizontal bar, the other end is provided with screw thread, above described screw thread, be rotary with two nuts, between two nuts, accompany draw-in groove, draw-in groove bottom perk, screw is left at top at a certain distance, described draw-in groove top is provided with beam bar, is provided with at a certain distance bolt above beam bar, and bolt screws in screw the inside simultaneously, is connected with water proof rubber bar between beam bar.
Described water proof rubber bar below is also provided with polystyrene foam plastics.
Described water proof rubber bar cross sectional shape is the net diamond structure that interweaves, and adopts mould of plastics injection molded.
Described draw-in groove material is aluminium, adopts casting mold moulding by casting.
Described beam bar top is provided with " V " font notch, and a side offers zigzag mouth.
The utility model has the advantages that: by by existing single track " C " font water-proof sealing rubber strip structural modification conclusion of the business knitmesh diamond structure, even the single structure fracture damage interweaving like this above net diamond structure, its entirety still has waterproof sealing effect.In rubber strip bottom, polystyrene foam plastics is installed simultaneously, like this water proof rubber bar is had to insulation effect, make its distortion of being expanded with heat and contract with cold little, improve its application life, reduce and change number of times, reduce costs.It is fragile that the utility model has effectively solved the water-proof sealing rubber strip single structure of existing bridge extension joint, and the problem that application life is short, is applicable to promoting the use of.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, bridge expansion joint installation, comprise pre-buried dowel 1, square dowel 2, horizontal bar 3, rear pouring concrete 11 and bridge main body 13, between described bridge main body 13 beam bodies, be provided with the trough with straight angle 15 of certain width, square dowel 2 is transversely arranged being located at above trough with straight angle 15 at a certain distance, horizontal bar 3 interts in square dowel 2 inner sides as muscle in it, the described pre-buried dowel 1 Integral bending structure that meets at right angles, be placed on above a part of horizontal bar 3, pre-buried dowel 1 two ends are placed in bridge main body 13 inside and just square dowel 2 and horizontal bar 3 are fixed like this, it is connected with bridge main body 13 indirectly, increase its stability, after each dowel connects on request, rear pouring concrete 11 is cast in above trough with straight angle 15, and each dowel is thoroughly fixed on rear pouring concrete 11 the insides like this, fixing muscle 10 has been tied up in described square dowel 2 inside, and fixing muscle 10 one end are bent into right angle and are inserted between horizontal bar 3 fixingly, and the other end is provided with screw thread 9, described screw thread 9 is rotary with between 7, two nuts 7 of two nuts and tightens and accompany draw-in groove 6 above, draw-in groove 6 bottom perks, and screw 16 is left at top at a certain distance, draw-in groove 6 tops are provided with beam bar 8, and beam bar 8 is provided with bolt 4 above at a certain distance, and bolt 4 screws in screw 16 the insides simultaneously, is connected with water proof rubber bar 5 between beam bar 8.
