Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.
As shown in figures 1-3, precast box girder activity steel reinforcement cage mould of high-speed railway, including fixed bolster and movable support, wherein, the fixed bolster is by left socle 1.1, the right branch frame 1.2 that the channel-section steel welding formed and lie in lower intermediate support 1.3 between the two and constitute, its bottom links to each other with the pre-buried steel sheet 2 welding in ground. The top surface of above-mentioned left socle 1.1 and right branch frame 1.2, the top surface of medial surface and intermediate strut 1.3 constitute with the ligature face of single line case roof beam steel reinforcement cage lateral surface looks adaptation, to the intermediate strut 1.3 top surface that does not hinder the steel reinforcement cage hoist and mount, the welding has fixed reinforcing bar card to put the piece on it, this fixed reinforcing bar card is put the piece and is seted up notched bracing piece 3 for the top surface, in order to form firm support to the reinforcing bar, above-mentioned bracing piece 3 constitutes latticedly along horizontal and vertical staggered arrangement. And the inner side surfaces of the left support 1.1 and the right support 1.2 are provided with movable steel bar clamping pieces through the translation supporting units, and the movable steel bar clamping pieces are horizontal rods 4 with grooves formed in the top surfaces. The supporting rod 3 and the horizontal rod 4 are both made of angle steel convenient to weld and groove, and the distance between the grooves on the supporting rod and the horizontal rod is determined according to the binding requirement of a reinforcement cage. The horizontal rods 4 are arranged in parallel to the inner side surfaces of the left support 1.1/the right support 1.2, the horizontal rods 4 on each side are at least one row (two rows in the figure), each row of the horizontal rods 4 is at least one section, and each section of the horizontal rods 4 is at least connected with one translation supporting unit. The translation supporting unit structure is the same, all including the horizontal track 5.1 of making by the channel-section steel of welding on 1.1 of left socle/right branch frame 1.2, install coaster 5.2 that pulley and layer board constitute on horizontal track 5.1, coaster 5.2 can move along the fixed bolster cross section on horizontal track 5.1, coaster 5.2 layer board is close to ligature face one end and links to each other with movable reinforcing bar card putting piece (horizontal pole 4), first hole 5.3 and second hole 5.4 have been seted up to the other end, it constitutes the locking Assembly with set up bearing hole and supporting round pin axle 5.5 on 1.1 of left socle and right branch frame 1.2. The distance between the first hole 5.3 and the second hole 5.4 is larger than the thickness of the concrete cushion block outside the steel reinforcement cage of the box girder, and is usually 15-25 cm. When the first hole 5.3 corresponds to the socket hole and is locked by the pin shaft 5.5, the horizontal rod 4 extends out (see figure 2), the reinforcing steel bars are placed in the grooves of the supporting rod 3 and the horizontal rod 4 for binding a reinforcing steel bar cage, and then the concrete cushion block is bound; when the second hole 5.4 corresponds to the socket hole and is locked by the pin shaft 5.5, the horizontal rod 4 retracts (see figure 3), the whole single-line box girder steel reinforcement cage and the concrete cushion block at the outer side of the steel reinforcement cage do not interfere with the fixed support, and therefore the bound steel reinforcement cage can be directly lifted out of the fixed support.
