Example 1

As shown in fig. 1 to 4, the utility model discloses the preferred embodiment of vertical reinforcement bed-jig of prefabricated box culvert is including bearing seat 1, skeleton 2 and bearing board 3. The bearing seat 1 is used for bearing a reinforcement cage or concrete, bearing the reinforcement cage when the reinforcement cage is pricked, and bearing the concrete in the concrete pouring process. Bear 1 middle part cavity of seat, cavity position department is arranged in to skeleton 2, on the rear end vertical welding skeleton 2 of bearing board 3, bearing board 3 is used for the bearing reinforcing bar, bearing board 3 is located the top of bearing seat 1, and the seat 1 that is convenient for bear can support the steel reinforcement cage. The framework 2 is roughly quadrangular, at least two groups of bearing plates 3 are arranged on each side, and each group of bearing plates 3 is formed by arranging a plurality of bearing plates 3 from top to bottom in sequence at equal intervals. The two load bearing members 21 in the lengthwise direction of the framework 2 are connected by the reinforcing beam 5 to increase the strength of the framework 2.

Two grooves 31 are formed in the bearing plate 3, reinforcing steel bars are placed in the grooves 31 to limit the reinforcing steel bars not to move along the length direction of the bearing plate 3, and the number of the grooves 31 is determined according to the number of the reinforcing steel bars designed by a reinforcement cage. The width of recess 31 is greater than or equal to the diameter of reinforcing bar, just the difference between the width of recess 31 and the diameter of reinforcing bar is less than or equal to 2mm, is convenient for place the reinforcing bar and can ensure the position of reinforcing bar, so can ensure that the error between the adjacent reinforcing bar is less, and the precision of the position that the reinforcing bar was placed is high. The bearing plate 3 is made of angle steel, and the groove 31 is formed by cutting the angle steel, so that the assembly and the processing are facilitated. The length of the supporting plate 3 is set according to the thickness of the box culvert, and is usually 60 mm.

Skeleton 2 includes bearing component 21 and first coupling beam 22, bearing component 21 distributes on each side of waiting to make the box culvert, bearing component 21 is used for fixed bearing board 3, and adjacent bearing component 21 forms a support body through first coupling beam 22 is fixed, ensures 2's of skeleton stability, is difficult for empting and scatter the frame. The adjacent bearing components 21 are welded through the two first connecting beams 22, and the two first connecting beams 22 are distributed up and down, so that the connection stability between the adjacent bearing components 21 is enhanced.

The bearing component 21 comprises two bearing upright columns 211 and two second connecting beams 212, the bearing plates 3 are welded on the bearing upright columns 211 along the vertical direction, the straight lines formed by connecting the two bearing upright columns 211 are parallel to the edges corresponding to the box culvert to be manufactured, and the steel bars are ensured to be parallel to the edges corresponding to the box culvert to be manufactured. The two ends of the second connecting beams 212 are respectively welded on the two bearing upright posts 211, and the two second connecting beams 212 are distributed one on the other, namely one second connecting beam 212 is welded at the upper end of the bearing upright post 211, and the other second connecting beam 212 is welded at the lower end of the bearing upright post 211, so that the bearing component 21 is high in overall stability, and the bearing component 21 is more easily arranged to be parallel to the corresponding edge of the box culvert to be manufactured. The number of the bearing upright posts 211 is increased or decreased according to the length of the box culvert.
