The specific embodiment
Below in conjunction with accompanying drawing the present invention is made detailed explanation.
Like Fig. 1, shown in Figure 2; The detachable slide block that is used for sliding construction provided by the invention; Comprise slide block distribution beam 1 and the piston shoes 2 that are arranged at slide block distribution beam 1 below; Piston shoes 2 are two and are symmetrically arranged along slide block distribution beam 1 length direction, and it is fixing that slide block distribution beam 1 and piston shoes 2 are connected through bolt, and the dismounting that this connected mode is convenient to slide block distribution beam 1 and piston shoes 2 separates.
Slide block distribution beam 1 comprises spandrel girder 3, first slide plate 11 and counter-force seat 12.Spandrel girder 3 is welded as a whole by shaped steel 13 and ribs 14; Shaped steel 13 comprises horizontal part 131 and vertical portion 132; Vertically portion 132 is two, and ribs 14 is vertical steel plate and is welded between two horizontal parts 131 that this structure design of spandrel girder 3 can guarantee that it bears bigger load; First slide plate 11 is fixed on the end face of spandrel girder 3; First slide plate 11 is two and is symmetrically arranged along slide block distribution beam 1 length direction; The friction factor on first slide plate, 11 surfaces is minimum, has reduced the frictional resistance of beam section 5 bottom in horizontal adjustment process greatly; Counter-force seat 12 is welded on the end face of spandrel girder 3; Counter-force seat 12 is two and lays respectively at the right ends of spandrel girder 3; Counter-force seat 12 is used to cooperate the lateral attitude of horizontal jack pair beam section 5 to adjust; The outside of counter-force seat 12 is welded with a trapezoidal counter-force seat supports plate 121, and 121 pairs of counter-force seats 12 of counter-force seat supports plate play the effect of reinforcing.
Piston shoes 2 comprise bearing block 4, second slide plate 24 and limited block 23.Bearing block 4 is welded as a whole by steel plate 21 and stiffener 22, and steel plate 21 is two and horizontal arrangement up and down, and stiffener 22 is welded between two steel plates 21 and vertically and arranges; Second slide plate 24 is fixed on the bottom surface of bearing block 2; The front and back free end of second slide plate 24 is provided with arc kink 241 upwards; Arc kink 241 makes sliding of second slide plate 24 more smooth and easy; The friction factor on second slide plate, 24 surfaces is minimum, has reduced the frictional resistance of piston shoes 2 in slipping greatly; Limited block 23 is welded in the outer end, bottom surface of bearing block 4; Limited block 23 is used for controlling the lateral shift of piston shoes 2 in slipping and is no more than restriction; The outside of limited block 23 is welded with a trapezoidal limited block gripper shoe 231, and 231 pairs of limited blocks 23 of limited block gripper shoe play the effect of reinforcing.
As shown in Figure 3, the applying step of detachable slide block provided by the invention in sliding construction is following:
At first slide block distribution beam 1 and piston shoes 2 are connected into whole slide block through bolt in advance; Beam section 5 hangs onto on the slide block distribution beam 1 of two detachable slide blocks after being transported to bridge location, on slideway 6, utilizes traction or incremental launching device that beam section 5, slide block distribution beam 1 and piston shoes 2 edge are together indulged bridge to sliding onto design attitude.
Cooperate jack 8 to regulate the lateral attitude of beam sections 5 through the counter-force seat on the slide block distribution beam 1 12 then, adjustment accomplish the back with jack with the slightly vertical jack-up of slide block distribution beam 1, the load that removal piston shoes 2 are born; Remove connecting bolt between piston shoes 2 and the slide block distribution beam 1; Laterally extract piston shoes 2 out, cushion block 9 that will be highly identical with piston shoes 2 fills up between slide block distribution beam 1 and slideway 6, again removal jack oil pressure; The weight of beam section 5 is transferred on the cushion block 9; Accomplish pad, so far beam section 5 straight skiddings and piston shoes 2 mask works finish, and the piston shoes of changing 2 can be used for the sliding construction of next beam section 5.The height of cushion block 9 is merely the height of piston shoes 2, and cushion block 9 volumes are little, material province, in light weight, change convenient to operation.
The detachable slide block that is used for sliding construction provided by the invention is removed piston shoes 2 and only need be used small-sized plant equipment with the operation of changing cushion block 9 in work progress, convenient to operation, just can accomplish at short notice, and efficiency of construction significantly improves.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under enlightenment of the present invention, making, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
