Description
Technical field
The present invention relates to bridge expansion joint installation, specifically a kind of freely-supported base spiral shell anchor formula comb plate stretching device.
Background technology
At present, comb plate stretching device occupancy volume is more, the time of use also the earliest, but result of use is poor, the problem of exposure is also more.Comb-shaped expansion device is divided into two kinds by mechanics form: one is simply-support comb-shaped expansion device, and another kind is cantilevered comb-shaped expansion device, structure has comb across seam and the comb junction of the edges of two sheets of paper point, connection has bolt anchoring and welding anchoring divide.Simply-support comb-shaped expansion device can be divided into two kinds again, and one is traditional simply-support comb-shaped expansion device (namely the real wide plate of movable comb tooth plate is across seam), and another kind is that tooth is across seam comb-shaped expansion device.Tradition simply-support comb-shaped expansion device has advantage easy to maintenance etc., but also exist that steel using amount is many, poor flatness, the sense of jumping car obviously, the defects such as complicated, installation rate is slow, nut easily gets loose and application life is short are installed.But its anti-dust performance is better, convenient maintenance and replacement.Tradition simply-support comb-formed retractable device some months at least, at most once occurring damaging phenomenon to 2 years, produce and seriously jump car, noise disturbs residents, the direct stationarity affecting vehicle and travel, hamper normal traffic, have impact on the durability of bridge deck structure and attractive in appearance, easily cause traffic accident, very big workload is brought to maintenance.
Tooth is across seam simply-support comb-shaped expansion device, not only maintain the advantage of traditional simply-support comb-shaped expansion device, also solve the shortcoming that it exists simultaneously, as steel using amount can reduce 20 ~ 30%, bridge is longitudinally installed width and is reduced, and can reduce vehicle and jump car, construction technology is simple, installation rate is accelerated, and the duration shortens.But, tooth is less across the application of seam simply-support comb-shaped expansion device, Shortcomings part is exactly rubbish, foreign material will drop in watertight rubber band from backlash, and remove foreign material very difficult, foreign material rubbish is cumulative, not only to block spilled water hole and affect draining, also to affect watertight rubber band dilatation, once watertight rubber band is damaged, could change after comb steel plate will being removed during exchange, repair cost is high, and long-standing problem promotes tooth across seam simply-support comb-shaped expansion device thus.
The comb plate stretching device of prior art can not adapt to the needs of the development that China's speedway and urban elevated bridge are built, and also exists and installs that complexity, poor flatness, the sense of jumping car are obvious, the structural safety defects such as low and application life is short by force.
Summary of the invention
The object of the invention is a kind of freely-supported base spiral shell anchor formula comb plate stretching device designed for the deficiencies in the prior art, adopt the braced structures of spiral shell anchor formula base, the assembling of in-site installation component and comb plate is verified to complete in factory, site work amount greatly reduces, improve installation quality and application life, accelerate the speed of in-site installation, maintenance and replacing, preferably resolve the field erected workload of comb plate stretching device large, low precision and slow-footed difficulties.
Realizing concrete technical scheme of the present invention is: a kind of freely-supported base spiral shell anchor formula comb plate stretching device, comprise the swing tooth plate that dropproof steel plate is welded in fixed tooth plate and comb-tooth segments bottom surface, fixed tooth plate has rubber fastening band, be characterized in that fixed tooth plate intersects horizontal on dropproof steel plate mutually with the comb of swing tooth plate, its swing tooth plate and fixed tooth plate rear end are arranged on two anchoring base by anchor foundation plate respectively and are fixedly connected with two anchoring base by bolt, the nose of comb of swing tooth plate is arranged on sliding base by dropproof plate, dropproof plate and stainless steel slide plate are for being slidably connected, swing tooth plate and fixed tooth plate with anchor foundation plate for welding, a described anchoring base is welded by several nut seat and anchoring riser and angle steel, another anchoring base described is welded by several nut seat and anchoring riser and base plate, the plate bearing that described sliding base is welded with two transverse slats and several riser by stainless steel slide plate, sliding base side is provided with baffle plate, and baffle plate and riser are for welding, under described rubber fastening band is arranged on the swing tooth plate between an anchoring base and sliding base, rubber fastening band is fixedly connected with angle steel with baffle plate by steel clamp board component.
Described stainless steel slide plate both sides embed two transverse slats with right-angle bending, and two transverse slats to be arranged on several riser and with stainless steel slide plate and riser for welding.
Described swing tooth plate and fixed tooth plate rear end are respectively equipped with side shield.
The assembling verification that the present invention compared with prior art has in-site installation component can complete in factory, site work amount greatly reduces, improve installation quality and application life, accelerate the speed of in-site installation, maintenance and replacing, preferably resolve the field erected workload of comb plate stretching device large, low precision and slow-footed difficulties.
