Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, relates to a waterproof structure of a bridge expansion joint, and particularly relates to a plug-in type waterproof device for a bridge expansion joint. Background Technique

[0002] A waterproof structure is usually required for a bridge expansion joint to converge rainwater into the drainage system of the bridge itself and prevent rainwater from directly flowing onto the cross beam and the bearing, which may cause damage to the bridge structure.

[0003] The existing bridge expansion joint devices mainly include modular expansion joints and comb-tooth plate type expansion joints. The modular expansion joint includes multiple middle cross beams and side cross beams arranged transversely to the bridge. Its waterproof structure is to set rubber water stops between the middle cross beams and between the middle cross beam and the side cross beam, and the rubber water stop is connected with the middle cross beam and the side cross beam as a whole; the comb-tooth plate type expansion joint mainly includes two comb-tooth plates respectively fixed on the top surfaces of the beam segments on both sides of the expansion joint, and the teeth of the two comb-tooth plates are arranged in an interleaved manner. Its waterproof structure is to directly press a waterproof plate under the comb-tooth plate.

[0004] Under the natural environment, due to material aging and the corrosion of dust and acidic rainwater, the waterproof device is prone to damage and needs to be replaced. However, once the rubber water stop of the existing modular expansion joint device is damaged, the cross beam needs to be removed and replaced as a whole, with a relatively high cost; once the waterproof plate of the comb-tooth plate type expansion joint is damaged, the comb-tooth plate needs to be removed to replace the waterproof plate, with a cumbersome process and a long construction time. Moreover, both of them need to temporarily close the traffic on the bridge, which has a great impact on road traffic. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems and provide a plug-in type waterproof device for a bridge expansion joint, which is convenient for replacement and does not affect the traffic on the bridge during replacement.

[0006] The technical solution of the utility model is as follows:

[0007] A pluggable waterproof device for bridge expansion joints, characterized in that it comprises two angle steels and a rubber waterproof plate. Each angle steel includes a first angle steel side and a second angle steel side. The outer side of the first angle steel side faces upward, and a limiting rod is longitudinally welded on the edge of the first angle steel side. The diameter of the limiting rod is greater than the thickness of the angle steel. The edge of the second angle steel side faces downward, and the outer sides of the second angle steel sides of the two angle steels are arranged opposite to each other. The rubber waterproof plate is arranged in a U shape between the two angle steels. The two sides of the rubber waterproof plate are respectively attached to the inner sides of the second angle steel sides of the two angle steels and are connected to the second angle steel sides of the two angle steels through a plurality of bolts. In the concrete of the beam segments on both sides of the bridge expansion joint, a socket is preset transversely. The diameter of the socket is greater than the diameter of the limiting rod. A notch is opened on the end face of the beam segment for the socket. The width of the notch is less than the diameter of the socket and greater than the thickness of the angle steel. The limiting rods welded on the two angle steels are respectively inserted into the sockets on the two beam segments, and the first angle steel sides of the two angle steels are respectively inserted into the notches on the two beam segments.

[0008] In the utility model, the waterproof device and the expansion joint device are set as a split structure. Only plugging holes need to be reserved at the beam ends on both sides of the expansion joint. The waterproof device is installed and disassembled in a plugging manner. When replacing, it is operated from the outside of the bridge without disassembling the expansion joint device, which does not affect the traffic on the bridge. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown in the figure, the utility model includes two angle steels 1 and a rubber waterproof plate 2. Each angle steel 1 includes a first angle steel side 11 and a second angle steel side 12. The outer side of the first angle steel side 11 faces upward, and a limiting rod 3 is longitudinally welded on the edge of the first angle steel side 11. The diameter of the limiting rod 3 is greater than the thickness of the angle steel 1. The edge of the second angle steel side 12 faces downward, and the outer sides of the second angle steel sides 12 of the two angle steels are arranged opposite to each other. The rubber waterproof plate 2 is arranged in a U shape between the two angle steels 1. The two sides of the rubber waterproof plate 2 are respectively attached to the inner sides of the second angle steel sides 12 of the two angle steels and are connected to the second angle steel sides 12 of the two angle steels through a plurality of bolts 4. In the concrete of the beam segments 5 on both sides of the bridge expansion joint, a jacking hole 6 is preset transversely. The diameter of the jacking hole 6 is greater than the diameter of the limiting rod 3. A notch 7 is opened on the end face of the beam segment for the jacking hole 6. The width of the notch 7 is less than the diameter of the jacking hole 6 and greater than the thickness of the angle steel 1. The limiting rods 3 welded on the two angle steels are respectively inserted into the jacking holes 6 on the two beam segments, and the first angle steel sides 11 of the two angle steels are respectively inserted into the notches 7 on the two beam segments.

[0014] In the above structure, the waterproof rubber plate is fixed to the angle steel. Due to the action of the limiting rod, the angle steel is limited on the beam segments on both sides of the expansion joint. The rainwater on the bridge deck flows down from above the expansion joint and converges on the rubber waterproof plate, and then flows into the bridge drainage system through the drain pipe connected to the rubber waterproof plate.

[0015] As Figure 4 shown in the figure, when the utility model is used in the processing of precast beams, jacking holes and notches are reserved at the ends of the concrete of each beam segment. When installing the expansion joint waterproof device, first connect and fix the waterproof rubber plate 2 and the two angle steels 1 with bolts 4, and then insert the two limiting rods 2 and the angle steel sides 11 into the jacking holes 6 and notches 7 at the ends of the beam segments on both sides of the expansion joint from one side of the bridge.

[0016] When the utility model is specifically implemented, for the convenience of installation and disassembly, through holes 13 can be preset at both ends of the second angle steel side 12 of each angle steel 1. During installation, when the limiting rod and the front end of the angle steel are inserted into the jacking hole and the slot on the beam segment and pushed forward, if the frictional force is large and it is laborious to push manually, a towing rope can be connected through the through hole at the front end of the angle steel, and a winch or a manual hoist can be used to connect the towing rope for pulling.

[0017] When the rubber waterproof plate is damaged and needs to be replaced, pull out the angle steel from one side of the bridge, replace the rubber waterproof plate and reinstall it.
