Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 to Fig. 4, a kind of large-scale bridge support grouting mould bases, this mould bases mainly comprises four pieces of templates, 1, four pieces of templates and mutually encloses and be fastenedly connected formation grouting die cavity 1-1; The upper and lower surface of described each four pieces of templates is equipped with upper mounting plate 1-2 and lower installation board 1-3; Above-mentioned template also can adopt C shape channel-section steel to replace, and described channel-section steel should meet load bearing requirements; Have at least one group of relative template upper surface to be provided with swinging bridge pad supporting mechanism 2 in above-mentioned four pieces of templates, described bridge pad supporting mechanism adjustable installing, on upper mounting plate 1-2, adopts adjustable structure to meet the adjustment of docking location between template.
Above-mentioned swinging bridge pad supporting mechanism 2 mainly comprises head tree 2-1, and the upper surface of described head tree is provided with center-pole 2-2; Described center-pole is set with revolving support cover 2-3; In order to avoid interfering at placement bridge pad head tree, the external diameter of described revolving support cover is concordant with enclosing post-grouting die cavity medial surface or have certain distance apart from medial surface; The excircle of described revolving support cover 2-3 is provided with gripper shoe 2-4 along revolving support cover axis direction, and the outward flange of described gripper shoe extends in grouting die cavity, and its degree of depth extends to bridge pad upper junction plate 3-1, and holds up bridge pad 3.The upper end of above-mentioned center-pole 2-2 is provided with thread segment 2-20, equipped locking nut 2-21 on described thread segment, the configuration of this locking nut mainly solves two technical problems, off center bar 2-2 when the first prevents revolving support to be enclosed within construction, it two is play locking effect, namely after placing bridge pad, revolving support cover is turned to grouting die cavity inward turning, rotate and lock to assigned address, thus avoid the revolving support cover adjusting to turn round, and then ensure the safety and stability of construction.
Rotary caging device 2-5 is provided with between described revolving support cover 2-3 and head tree 2-1; Described rotary caging device comprises the semicircle revolution breach 2-10 being arranged on head tree 2-1 upper end, and the two ends of revolution breach define limiting section 2-11; The soffit of corresponding revolution gap position revolving support cover is provided with the slewing limit block 2-30 of 1/4 circle, and described slewing limit block is inserted in revolution breach.This rotary caging device ensures that revolving support has two extreme positions when being enclosed within revolution, one is the extreme position before placing bridge pad, gripper shoe on this position revolving support cover is left above grouting die cavity, bridge pad is facilitated to be placed in grouting die cavity smoothly, another extreme position is Support Position, be positioned at below the upper junction plate being just in time positioned at bridge pad above grouting die cavity in this position gripper shoe, thus play picking-up supporting bridge bearing.
The soffit of described head tree 2-1 is provided with connecting screw rod 2-60, described connecting screw rod is inserted in the installing hole 1-20 of upper mounting plate, described installing hole is elongated hole, described connecting screw rod is fitted with two locking nuts 2-61,2-62, two locking nuts respectively spiral shell are contained on connecting screw rod, two locking nuts are distributed in the both sides up and down of the upper mounting plate 1-2 of template upper surface, and two above-mentioned locking nuts and connecting screw rod constitute and adjust head tree and be elevated, and fastening lift adjustment mechanism 2-6; This structure design mainly solves the problem adjusting axis and plane elevation after supporting bridge bearing is placed, by loosening and tightening the coarse regulation that can realize axis and elevation fast two locking nuts.
Four Angle Position of the mould bases that described four pieces of templates enclose are provided with fine setting footing 4, can carry out the fine setting to realizing axis and elevation, and then ensure that construction quality by fine setting footing.
Conveniently observe the levelness of template, have at least in described four pieces of templates in one group of adjacent forms and be provided with level gauge 5.
Concrete construction method, refer to Fig. 5, be first sleeved on the pinner 7 of bridge pier 6 upper surface four pieces of templates are enclosed mould bases, and ensure that each inner surface of template 1 and the side of pinner are close to, spillage during to prevent from being in the milk, now finely tunes the upper surface of bottom foot base at bridge pier, then the locking nut 2-21 on center-pole is unclamped, and open revolving support cover 2-3, then anchoring piece 8 is installed by the lower connecting plate of bridge pad, by boom hoisting, bridge pad is slowly placed in grouting die cavity 1-1, now anchoring piece is just in time aimed in the anchor hole 6-1 on bridge pier, when the lower connecting plate 3-2 of bridge pad 3 is descending, and after crossing revolving support cover 2-3, open revolving support cover to revolving support position, then the locking nut 2-21 of center-pole upper end is locked by revolving support cover locking, now bridge pad continues descending until bridge pad lower connecting plate 4-2 contacts with the upper surface of pinner 6 under the effect of boom hoisting, now by adjusting lift adjustment mechanism 2-4 to ensure axial location and the plane elevation of bridge pad according to actual conditions, and each limit whether level can be observed by level gauge 5, can be finely tuned by fine setting footing 4 if difference is less, after the axial location of above-mentioned regulating guarantee bridge pad and plane elevation, start grouting, wait decentering after grout cures, can once grouting be completed.
In sum, adopt technique scheme, in practice of construction process, disposablely can complete bearing axis and the adjustment of plane elevation, and carry out the construction of bridge support grouting operation smoothly, avoid repeating adjustment operation and each operation is mutually disturbed, increased work efficiency, the present invention also has revolving strong, easy installation and removal, solid and reliable, easy and simple to handle, construction control precision advantages of higher in addition.
The above is only to preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solution of the present invention.
