The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point; A kind of high pier shaft reinforced concrete continuous beam No. zero piece, a piece construction braced structures are provided; In the hope of simplifying construction technology, economical with materials and cost, shorten No. zero piece, a piece construction period.
The utility model technical solution problem provides following scheme:
A kind of to pull-type carriage purlin; Comprise the left and right bar that baroclines, left and right longeron; Two bars that barocline tilt to be installed in the left and right sides of pier shaft respectively about said, said about two barocline bar the bottom be fixedly connected with supporting seat on being embedded in pier shaft through supporting steel plate, said about two barocline bar the top be supported on the bottom of left-right longeron respectively; Said baroclining is provided with strut and tie between bar and the longeron; The two ends of said strut and tie are connected with longeron with the bar that baroclines respectively, and the top of said pier shaft is provided with the support pinner, are embedded with pull bar in the said support pinner; Connect between the longeron about said two ends to pull bar are fixedly connected on respectively, left-right longeron is drawn on the left and right sides sidewall that leans against pier shaft.
Said longeron, the bar that baroclines, strut and tie are Two bors d's oeuveres shaped steel, between Two bors d's oeuveres shaped steel junction plate are set and form integral body, and longeron all adopts and is welded to connect with the bar that baroclines, strut and tie contact position, and longeron web place adds stiffening rib in the contact position simultaneously.
Said fining twisted steel to pull bar employing PSB830 material φ 32mm is embedded in and supports in the pinner, and the steel plate that the pull bar two ends is provided with double nut and longeron welding is tightened.
The back-pressure bar vertically is installed respectively on the abutting end of two longerons about said, and said back-pressure rod member comprises vertical pull bar, and said vertical pull bar bottom is embedded in the pier shaft, and vertical pull bar adopts the fining twisted steel of PSB830 material φ 32mm.
Compare with full framing, steel pipe column bracket, the utility model beneficial effect is embodied in:
1. adopt pull-type carriage trussed construction construction, in construction, need not, without long period preparation material to the place sclerosis.
2. adopt pull-type carriage trussed construction construction, at the bottom of the support scaffolding height, workload significantly reduces; Reduce the technical difficulty that supporting structure is set up, thereby improved the safety and use flexibility of supporting structure.
3. adopt pull-type carriage trussed construction construction, material usage is few, greatly reduces operating expenses.
4. adopt pull-type carriage trussed construction construction, support is installed, dismantling operation is simple, has reduced the engineering time of work high above the ground, has reduced construction risk.
5. adopt pull-type carriage trussed construction construction, need not pre-buried pallet stringer in pier cap, it is dismountable that carriage brace bottom is provided with the bolt connection, and the carriage truss can reuse.
6. adopt pull-type carriage trussed construction construction, increased pallet stringer and the concrete contact area of pier cap, reduced concrete concentrated stress effectively at pier cap end face pre-buried steel backing plate.
7. adopt pull-type carriage trussed construction construction, reduced on the longeron end at use back-pressure bar on the longeron and scratched distortion.
