Seat cushion stone passes to substructure and basis, is one of the component that bridge force-bearing is concentrated the most, is the important composition of bridge structure
Part, its quality directly affect the service life and structure safety of bridge, and it has big small volume, stress, stress concentration, divided
Cloth reinforcing bar is close, construction precision requires the characteristics of high.
Bearing installation will ensure the horizontal and smooth of bearing support face, and the corner discrepancy in elevation in bearing support face cannot be greater than 2mm,
And can not occur coming to nothing between bearing and pinner, bias and Non even supporting etc. is by force phenomenon, must there is at a relatively high absolute altitude at supporting
Precision, must have good flatness with the contact surface of bearing so spherical bearing pinner is by the way of post forming
Constructed, i.e., pour the height of reserved 20mm during pinner for the first time, reinstall template, with ungauged regions, early strong, high-strength mortar
The method of pouring is adjusted, and such construction precision, quality can meet requirement.But at present during box beam erection,
The conventional method of bearing pad stone back-grouting is formed with the bamboo slab rubber of four corresponding width, iron nail connection, scene after terminating
Remove, be easy to damage during tearing open, can only typically have enough to meet the need secondary, waste is big, and seam is less tight, spillage phenomenon compared with
To be serious, and corner discrepancy in elevation precision is extremely difficult to design specification requirement, can there is the problem of seat empty.
The content of the invention
Goal of the invention：The utility model purpose is in view of the shortcomings of the prior art, there is provided a kind of convenient disassembly, installation
Precision is high, and efficiency of construction is high and avoids the back-grouting device for track bridge spherical bearing of seat empty problem.
Technical scheme：A kind of back-grouting device for track bridge spherical bearing described in the utility model, including
Pattern plate bolster and the height adjustment assembly positioned at pattern plate bolster corner, the pattern plate bolster are made up of the consistent L-type template of four chip sizes, institute
The outside headtotail successively of L-type template opening is stated, the pattern plate bolster of closure is formed, in the L-type template there is pattern plate bolster bore to adjust
Component is saved, passes through the grouting bore of the bore adjusting part accurate adjustment pattern plate bolster；One end of the height adjusting part is fixed
In L-type template, the other end is fixed on bridge pad pinner, and mould is adjusted by the relative distance for adjusting height adjusting part both ends
The height of sheet frame.
Further, installed in the bore regulating tank and regulating tank that the bore adjusting part includes opening up in L-type template
Fastener, the long slab of adjacent L-type template is respectively provided with supporting bore regulating tank with short slab, and the fastener includes fastening spiral shell
Bolt, fastening nut and pad, the fastening bolt are plugged in the bore regulating tank and by fastening nut and pad lock-bit.
Further, the height adjustment assembly includes height adjustment bolt and height regulating nut, the height regulation
It is bolted on bridge pad pinner, and screw thread is upward, the height regulating nut is fixed on the same position of the L-type template
Put.
Further, there is the fixed cylinder matched with height adjustment bolt, height adjusts spiral shell on the bridge pad pinner
The bottom of bolt is plugged in the fixed cylinder, realizes the relative rotation of height adjustment bolt and fixed cylinder.
Further, the circle of template frame bottom one is provided with only slurry adhesive tape.
Further, four L-type templates of the pattern plate bolster are equipped with level meter.
Further, the L-type template is steel plate material.
Beneficial effect：（1）Template in the present apparatus is made up of four L-type steel plates, is added only in template bottom during installation
Adhesive tape is starched, the relative altitude of template and bearing pad stone top is regulated, then tightens up dies plate tap bolt；Soon can be complete
Into whole model sheetinstallat process；It is directly alarmed and panicky during form removal to open corner fastening bolt, form removal process is just completed, quick construction is convenient,
Relative to traditional bamboo slab rubber is framed there is bore easily to adjust, the advantages of position adjustments are accurate, and then ensure grouting high-quality and high-efficiency
Complete, and the problem of be not in spillage and seat empty；（2）Pattern plate bolster in the present apparatus is steel plate material, is being dismounted
It is hardly damaged in journey, is easy to be used in turn and service life is higher, is reduced construction input, improve stock utilization.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present apparatus；
Wherein：1st, L-type template, 2, bore regulating tank, 3, height adjustment bolt, 4, height regulating nut, 5, bridge pad
Pinner, 6, fixed cylinder.
Embodiment
Technical solutions of the utility model are described in detail below by accompanying drawing, but the scope of protection of the utility model
It is not limited to the embodiment.
Embodiment 1：A kind of back-grouting device for track bridge spherical bearing, including pattern plate bolster and positioned at pattern plate bolster
The height adjustment assembly of corner, pattern plate bolster are made up of the consistent steel plate material L-type template 1 of four chip sizes, and L-type template opening is outside
Headtotail successively, the long slab of adjacent L-type template and short slab have supporting bore regulating tank 2, and fastening bolt is plugged on mouth
In the regulating tank of footpath and by fastening nut and pad lock-bit, the pattern plate bolster of closure is formed, the circle of template frame bottom one, which is provided with, only starches adhesive tape；
