Abstract
It include corresponding side bar deformed steel and rubber fastening band in composition the utility model discloses a kind of bridge extension joint.There is clamping groove on side bar deformed steel, the structure that is caught in of rubber fastening band is inserted into clamping groove, being caught in below structure for rubber fastening band has the duct parallel with rubber fastening band, upper end is overhead structure, there is fin on the inside of the barbed end of the overhead structure, metallic water stop tie is installed, metallic water stop tie is V-shape above rubber fastening band, the structure that is caught at its both ends matches with the overhead structure interior shape of rubber fastening band, is just stuck in rubber fastening band overhead structure.Metallic water stop tie has toughness strong, and shock resistance is corrosion-resistant, ageing-resistant, and the advantages of the rubbish extrusion damage rubber fastening band such as can prevent sleet dust storm and rubble.
Description
Technical field
The utility model discloses a kind of bridge extension joints, belong to bridge expansion joint installation field.
Background technique
Telescopic device is the important composition component of bridge, and what the quality of performance directly influenced bridge telescopicing performance can
It leans on, the safety of vehicle operation.But due to design, production, installation, maintenance aspect, there are many telescopic devices to damage every year
It is bad.Rubber fastening band plays water-proof function in expansion joint and improves the vital function of bridge service life.Common
Expansion joint rubber fastening band usually it is exposed outside, exposing to the weather easily aging or by pressure injury, and becoming in temperature in four seasons
Change repeatedly telescopic process and be also easy abjection fashioned iron, loses sealing water-proof function, therefore rubber fastening band needs frequent maintenance and replacement.Separately
The exposure of outer rubber waterstop leads to summer easily aging, and winter is easy stiff forfeiture elasticity.If rubber fastening band is by outer
Power damage will cause infiltration, under the influence of square beam bottom support use function and service life, if while replace not in time, in pier
Armored concrete also will receive corrosion, since expansion joint rubber rubber fastening band damages, road debris falls into expansion joint, is stuck in
Chance temperature change will squeeze beam head or platform back bad in seam.Drop heavy rain is met after rubber fastening band damage, a large amount of rainwater are poured into along seam
Unprotected end of the bridge slope protection makes slope protection a large amount of damaged or destroyed by flood occur.While leak at bridge pier or platform, northern territory is peculiar in addition
Freezing-thawing damage, deicing salt salt wound of deteriorating induce other different degrees of diseases.If things go on like this, the use of bridge is greatly influenced
Safety.
Utility model content
The purpose of this utility model is to disclose that a kind of toughness is strong, and shock resistance is corrosion-resistant, ageing-resistant, for preventing sleet wind
The rubbish such as husky and rubble cannot be cleared up in time and the bridge extension joint of extrusion damage rubber fastening band.
A kind of bridge extension joint includes corresponding side bar deformed steel and rubber fastening band, side bar deformed steel in composition
On have clamping groove, the structure that is caught in of rubber fastening band is inserted into clamping groove, and rubber fastening band is caught under structure
The parallel duct of Fang Youyu rubber fastening band, upper end are overhead structure, have fin on the inside of the barbed end of the overhead structure.
The duct of a kind of above-mentioned bridge extension joint, the rubber fastening band being caught in below structure is at least 1.
A kind of above-mentioned bridge extension joint installs metallic water stop tie, metallic water stop tie above the rubber fastening band
For stainless steel panel, the metallic water stop tie is V-shape, and both ends are caught in the overhead structure of structure and rubber fastening band
Portion's shape matches, and is just stuck in rubber fastening band overhead structure.
Using the bridge extension joint of the structure, waterstop is divided into two parts, and top is stainless steel panel, and lower section is rubber
Waterstop, stainless steel panel is similar to ox horn " V " word shape, and toughness is strong, shock resistance, corrosion-resistant, ageing-resistant, for protecting sleet wind
Husky and rubble rubbish etc. cannot be cleared up and extrusion damage rubber fastening band in time, and protection delays the aging of waterstop, greatly improve
The service life of waterstop, the maintenance cost at expansion joint is reduced, rubber fastening band is caught in duct and overhead structure energy in structure
Enough prevent stainless steel from deviating from, the two combination keeps filling more substantial after filling in fashioned iron card slot, while interaction is more difficult to deviate from fashioned iron,
Avoiding the waterproof action at expansion joint after falling off from losing causes bridge leak to damage.In addition, rubber fastening band uses ethylene-propylene-diene monomer
Glue, more anti-aging, telescopic resilience is more preferable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the rubber fastening band of the utility model and the combining structure schematic diagram of metallic water stop tie.
Specific embodiment
Referring to Fig.1, Fig. 2, a kind of bridge extension joint include that corresponding side bar deformed steel 3,4 and rubber stop in composition
Water band 2 has clamping groove on side bar deformed steel, and the structure 21,22 that is caught in of rubber fastening band is inserted into clamping groove, rubber
There is the duct 41,42 parallel with rubber fastening band in the lower section for being caught in structure 21,22 of waterstop respectively, and upper end is barb knot
There is fin 31,32 in the barbed end inside of structure, overhead structure respectively, and rubber fastening band 1 installs metallic water stop tie 2, metal above
Waterstop 2 is stainless steel panel, and metallic water stop tie 2 is V-shape, the overhead structure for being caught in structure and rubber fastening band at both ends
Interior shape matches, and is just stuck in rubber fastening band overhead structure.
Waterstop is divided into two parts, and top is stainless steel panel, and lower section is rubber fastening band, and stainless steel panel is similar to ox horn
" V " word shape, toughness is strong, shock resistance, corrosion-resistant, ageing-resistant, for protecting sleet dust storm and rubble rubbish etc. clear in time
It manages and extrusion damage rubber fastening band, protection delays the aging of waterstop, greatly improves the service life of waterstop, reduces flexible
The maintenance cost of seam, the duct and overhead structure that rubber fastening band is caught in structure can prevent stainless steel from deviating from, the two combination
Rear plug is interacted and is more difficult to deviate from fashioned iron into making after fashioned iron card slot filling more substantial, and the waterproof at expansion joint after falling off is avoided
Action deprivation causes bridge leak to damage.In addition, rubber fastening band uses ethylene propylene diene rubber, more anti-aging, telescopic resilience is more
It is good.
