Abstract
The invention belongs to the technical field of bridge expansion devices, and relates to a sealing protection structure for a road bridge expansion device. The expansion device consisting of deformed steel and a sealing rubber belt is full of an elastic filling material; the deformed steel is embedded into the upper top of a bridge beam body; an expansion joint is formed on the beam body; the sealing rubber belt is clamped on the deformed steel on both sides; a V-shaped space is formed on the upper part of the sealing rubber belt; the elastic filling material is placed into the V-shaped space formed on the upper part of the sealing rubber belt, and is flush with the upper top surface of the bridge beam body; the elastic filling material is bonded together with the deformed steel; the filling material is a high polymer material, and is vulcanized into an elastomer in a natural state. Due to the adoption of the sealing protection structure for the road bridge expansion device, the service life of the road bridge expansion device is prolonged, the maintenance difficulty of the road bridge expansion device is lowered, the construction period is shortened, the road smoothness is improved, the influence of jumping is lowered, and the service life of a bridge is prolonged.
Description
Technical field
The invention belongs to bridge extension joint technical field, relate to a kind of Expansion Units for Highway Bridges sealed protective structure, be particularly useful for the maintenance of the Expansion Units for Highway Bridges of newly-built modulus type Expansion Units for Highway Bridges and the breakage of caulking gum band.
Background technology
Existing Expansion Units for Highway Bridges major part is modulus type Expansion Units for Highway Bridges, the caulking gum band of this stretching device is easily aging, often need to change, but due to vehicle flowrate, road face load difference, road surface temperature is uneven, and the deflection of stretching device different parts is also different, brings a lot of difficulties to replacing caulking gum band, change long in time limit, and the construction of need to opening circuit.Secondly deformed steel class stretching device regular maintenance project needs the foreign material that often accumulate between cleaning seam, and this has not only increased maintenance workload, and has increased surfaceman's potential safety hazard.
Summary of the invention
Object of the present invention is intended to overcome above-mentioned the deficiencies in the prior art part, and a kind of Expansion Units for Highway Bridges sealed protective structure is provided.Technical solution of the present invention is, in the stretching device that deformed steel and caulking gum band form, be full of elastic filling material, deformed steel embeds bridge beam body upper top, on beam body, form shrinkage joint, caulking gum band inlay card is on the deformed steel of both sides, and V figure space is formed at caulking gum band top, and elastic filling material is placed in the V figure space that caulking gum band top forms, and concordant with end face in bridge beam body, elastic filling material and deformed steel bond together.
Described deformed steel is C shape, E shape or F shape.
Described elastic filling material is macromolecular material, and under nature, sulfuration is elastic body.
Described elastic filling material is polysulfide sealant, organosilicon sealant, the polyurethane sealant of polysulfide sealant, organosilicon sealant, polyurethane sealant and modification.
Described a kind of Expansion Units for Highway Bridges sealed protective structure, has bonding primary coat or priming paint or cold primer between elastic filling material and deformed steel, improve the adhesive strength of elastic filling material and deformed steel.
The advantage that the present invention has and beneficial effect
In the life-span of having improved on the one hand Expansion Units for Highway Bridges according to a kind of Expansion Units for Highway Bridges sealed protective structure provided by the present invention, reduced the difficulty of Expansion Units for Highway Bridges maintenance, shortened the construction period, reduced regular maintenance cleaning works; The elastic filling material that this stretching device uses on the other hand has good damping vibration attenuation function, has effectively improved the stationarity on road surface, reduces to jump car impact, thus the life-span of improving bridge.In expansion gap device maintenance works, for damaged caulking gum band, can change direct perfusion elastic filling material.
