Detailed description of the invention
Installation mold is assisted to be described in detail below in conjunction with the drawings and specific embodiments to the bearing that the utility model provides.
Now be described for certain subway viaduct engineering: the bearing that this subway viaduct engineering adopts is pot rubber bearing, bearing model comprises 2000-GD, 2000-ZX-50mm, 2500-ZX-50mm, 3000-GD, 3000-ZX-100mm, 3000-ZX-50mm, 3500-GD etc. 24 kinds, totally 480.Bearing install whether put in place, it contacts whether closely connected tight with pinner, and whether prepared screw-bolt hole fills up tamping, all directly can affect the application life of bearing and the safety of bridge construction, will be very harmful to the safe operation of subway if there are quality problems.In order to ensure the installation quality of bearing, the bearing that this project selects the utility model to provide assists installation mold to carry out bearing installation, this installation mold lighter in weight, the plan-position of convenient adjustment bolt and elevation.After Bolt to position, pinner concreting and bearing are installed and are carried out simultaneously, both ensure that bearing installation site accurately in turn ensure that closely connected tight between pinner concrete and bearing.
As Figure 1-Figure 2, the bearing that the utility model provides assists installation mold to comprise auxiliary die plate 1, polylith timber wedge 3, multiple anchor bolt 4, many built-in pipes 5 and multiple bolt sleeve 8; Wherein to be vertically set on the top of pier stud 7 removably apart inner for many built-in pipes 5, for the formation of prepared screw-bolt hole 9; A bolt sleeve 8 is installed in each prepared screw-bolt hole 9; Auxiliary die plate 1 is horizontally set on the top of multiple prepared screw-bolt hole 9, and it is formed with multiple bolt positioning hole 2 corresponding with multiple bolt sleeve 8 position respectively; Polylith timber wedge 3 is arranged between the end face of pier stud 7 and the bottom surface of auxiliary die plate 1 apart; The lower end of each anchor bolt 4 is connected to the inside of a bolt sleeve 8 from the top down through bolt positioning hole 2 rear thread.
The height of described timber wedge 3 is identical with the thickness of bearing pad stone, and has plurality of specifications.
Described auxiliary die plate 1 is made up of one block of steel plate measure-alike with the lower support plate on bearing, and has plurality of specifications.
Described built-in pipe 5 is pvc pipe.
The construction method that the bearing now utilizing the utility model to provide assists installation mold to install bridge pad is described below:
1) before utilizing concreting pier stud 7, first accurately set many piece built-in pipes 5 at the position, top of pier stud 7 according to the relative position relation of multiple bolt sleeve 8 by staff, in this engineering, built-in pipe 5 is
pvc pipe, the pre-buried degree of depth is 50cm, and then concreting is to Dun Ding to make pier stud 7, extracts built-in pipe 5 after above-mentioned concrete initial set, forms multiple prepared screw-bolt hole 9 thus;
2) adopt total powerstation on the end face of pier stud 7, survey the center extension line coordinate setting out each anchor bolt 4 according to designing requirement, then the line of ink marker is used to be linked to be straight line on end face, check that whether the position of each prepared screw-bolt hole 9 is correct, water drilling is then adopted to carry out reaming, till meeting installation requirement as error is comparatively large;
3) adopt total powerstation to survey on the end face of pier stud 7 according to designing requirement and set out bearing pad stone four angular coordinate and bearing right-angled intersection position of center line, and adopt the line of ink marker on end face, eject the plan-position of bearing pad stone and bearing right-angled intersection center line, pinner corner location will mark clear, number and varnish with lacquer, more eye-catching like this and firmly, then measure pinner elevation with level gauge, select the timber wedge 3 of corresponding height afterwards according to pinner thickness;
4) auxiliary die plate 1 measure-alike with its lower support plate is selected according to bearing model, then bearing right-angled intersection center line 6 is accurately depicted at the surface line of ink marker of auxiliary die plate 1, again according to the perforate and form multiple bolt positioning hole 2 on auxiliary die plate 1 of the layout of multiple anchor bolt 4, then the lower end of multiple anchor bolt 4 is each passed through from the top down the inside that bolt positioning hole 2 rear thread is connected to a bolt sleeve 8, finally multiple bolt sleeve 8 is inserted in multiple prepared screw-bolt hole 9 simultaneously;
5) four pieces of timber wedges 3 are placed on respectively auxiliary die plate 1 below near the position of bearing right-angled intersection center line 6, then auxiliary die plate 1 is repeatedly moved, till making above-mentioned two bearing right-angled intersection center lines coincide with the upper and lower with reference to the bearing right-angled intersection position of center line on auxiliary die plate 1 upper bracket right-angled intersection center line 6 and pier stud 7 end face;
6) use level gauge to measure the end face absolute altitude of anchor bolt 4, repeatedly move timber wedge 3 till its end face absolute altitude reaches requirement;
7) in prepared screw-bolt hole 9, pour into a mould grouting agent from the side bolt sleeve 8 is fixed, after grouting agent final set, remove all anchor bolts 4, auxiliary die plate 1 and timber wedge 3, and anchor bolt 4 is inserted in the corresponding screw in the lower support plate of bearing to be installed;
8) dabbing process is carried out to the concrete of pinner placement on pier stud 7 end face, after digging out the new stubble of concrete, quarrel will be floated and remove clean, and then carry out pinner reinforcing bar binding, and make pinner template; Carry out pinner concreting afterwards and make pinner, before building, needing the upper end of bolt sleeve 8 to adopt non-woven fabrics to carry out shutoff, to avoid concrete to enter, more above-mentioned non-woven fabrics to be removed after building and by bolt sleeve 8 wiped clean;
9) crane gear is adopted bearing to be winched to the top face of pier stud 7, and slowly put down after the multiple anchor bolts 4 on it are aimed to corresponding bolt sleeve 8 multiple on Dun Ding respectively, until the lower end of anchor bolt 4 is inserted in bolt sleeve 8, tightens after anchor bolt 4 makes bearing slowly sink down into design elevation position and be fixed; Immediately bearing elevation of top surface and the corner discrepancy in elevation are tested, adjusted in time when error exceeds standard, until qualified; By pinner superelevation part concrete extrusion, can guarantee that rest base slurry is full closely knit, completes the installation process of whole bearing thus like this during settling of supports.
