At present, a replaceable telescopic device is arranged on the market, particularly on a railway bridge, the replaceable telescopic device is composed of a special-shaped section bar, a waterproof rubber belt, a rubber locking strip at the embedded part of the waterproof rubber belt and a cavity, and is installed by a special tool. The special tool is required to be used for dismounting when the rubber is dismounted after being damaged, the working efficiency is low, the universality of the special tool is poor due to the fact that the sizes of all beam seams are different, the number of the dismounting and mounting tools is large, and the replacement cost is high. And no matter highway bridge telescoping device or railway bridge telescoping device waterproof rubber strip do not have the wash port at bridge width within range now, cause and can not get rid of smoothly with water, even the roof beam body is washed to the drainage department at rubber waterproof strip both ends, causes the rainwater to corrode the damage.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a change convenience, cost of maintenance low, work efficiency is high, the timely removable bridge telescoping device of two section bars of drainage.
The technical problems are solved by adopting the following technical scheme:
a bridge expansion device with replaceable double profiles comprises anchor bars, a connecting block, outer special-shaped profiles, inner special-shaped profiles and a waterproof rubber belt, wherein the anchor bars are fixedly connected with the outer special-shaped profiles through the connecting block, the two end profile heads of the waterproof rubber belt are embedded in the inner special-shaped profiles, the inner special-shaped profiles are installed in cavities of the outer special-shaped profiles, the inner special-shaped profiles can slide in the cavities of the outer special-shaped profiles, the peripheral shape of the inner special-shaped profiles is matched with the shape of the cavities of the outer special-shaped profiles, and limiting platforms for preventing the inner special-shaped profiles from easily slipping off after being stressed are arranged at opening. Set up on the waterproof rubber strip and be no less than 2 drain pipes, prevent that the rainwater from piling up, get rid of inconveniently.
The bridge expansion device with the replaceable double profiles has the advantages that the anchor bars can be connected with the outer special-shaped profiles in a welding, riveting and bolting structure mode.
The double-section replaceable bridge expansion device is characterized in that the outer special-shaped section and the inner special-shaped section are made of steel or aluminum.
The bridge expansion device can be replaced by the double-section bar, and the cavity of the outer special-shaped section bar is circular, square or other irregular shapes.
Foretell removable bridge telescoping device of two section bars sets up on the waterproof rubber strip and is no less than 2 drain pipes, and there is the shutoff at waterproof rubber strip both ends.
The replaceable bridge expansion device with double profiles is installed at a bridge seam, when the waterproof rubber belt generates pest and disease damage function failure, only the inner special-shaped profile inlaid with the waterproof rubber belt needs to be drawn out from the cavity of the outer special-shaped profile, the waterproof rubber belt is drawn out from the inner special-shaped profile outside the beam seam, a new waterproof rubber belt is replaced, then the inner special-shaped profile inlaid with the new waterproof rubber belt penetrates into the cavity of the outer special-shaped profile from one side surface of the beam end, the replacement is smoothly completed, the replacement is convenient, the maintenance cost is low, and the working efficiency is high. When the rain falls, the rainwater in the waterproof rubber strip can be discharged to the ground along the water falling pipe, so that the corrosion of the rainwater to the beam body is prevented.

Detailed Description
Referring to fig. 1 and 2, the double-profile replaceable bridge expansion device comprises anchor bars 10 and 11, connecting blocks 20 and 12, outer special- shaped profiles 30 and 13, inner special- shaped profiles 40 and 14, a waterproof rubber belt 50 and a drain pipe 8, wherein the waterproof rubber belt plug 9 and the anchor bars 10 and 11 are fixedly connected with the outer special- shaped profiles 30 and 13 through the connecting blocks 20 and 12 respectively, two end profiles 70 and 17 of the waterproof rubber belt 50 with the drain pipe 8 and the plug 9 are embedded in the inner special- shaped profiles 40 and 14 respectively, the inner special- shaped profiles 40 and 14 are installed in cavities of the outer special- shaped profiles 30 and 13 respectively, the inner special-shaped profiles can slide in the cavities of the outer special-shaped profiles, the peripheral shape of the inner special-shaped profiles is matched with that of the cavities of the outer special-shaped profiles, the cavities of the outer profiles are square, and limiting tables 60 for preventing the inner special- shaped profiles 40 and 14 from easily slipping off after being stressed are arranged at opening, 16.
The anchor bars are connected by welding outer special-shaped profiles. Or can be connected with the special-shaped section bar in a riveting and bolting structural form. The outer special-shaped section and the inner special-shaped section are made of steel or aluminum.
The die cavity of the outer special-shaped section is round or in other irregular shapes.
The width of the opening part of the outer special-shaped section and the thickness of the limiting table do not influence the function of the waterproof rubber belt, and the strength of the limiting tables 60 and 16 meets the requirement of the maximum beam seam tension.
