The technical scheme of the utility model is: a frame-type support composed of a plurality of support front slanting bars on the front side, a plurality of support vertical bars on the rear side, and a plurality of support cross bars arranged at intervals in the transverse direction; At least two square steel pipes and multi-layer horizontal supports are distributed laterally from top to bottom on the front side formed by the plurality of bracket front slant bars, and each square steel pipe is spaced with a plurality of vertical notches along the length direction, and The vertical notches on the square steel pipes correspond to each other up and down; the bottom of the frame-type support is provided with supporting legs.

The above scheme is further preferably:

Preferably, the frame-type bracket includes multi-section repeating units, and the multi-section repeating units are connected as a whole through connecting pins. The formwork is freely divided into sections according to the construction strength and weight requirements, and the principle is to avoid deformation and facilitate manual movement.

Preferably, a transverse front end bottom support is provided at the front bottom end of the frame support, and the thickness of the front end bottom support is consistent with the thickness of the steel bar protective layer of the bottom plate. During installation, the front end bottom support is directly placed on the top surface of the box girder prefabricated pedestal, and the thickness of the front end bottom support is designed to be consistent with the thickness of the bottom plate steel protection layer, and it can also control the thickness of the bottom protection layer of the box girder slab.

Preferably, the slope of the front side formed by the front diagonal bars of the bracket is consistent with the slope of the web of the box girder.

Preferably, the height of the outrigger is smaller than the height of the prefabricated pedestal of the box girder.

The beneficial effects of the utility model are: the equipment is simple in structure, reasonable in design, easy to implement; convenient to move, easy to operate, easy to unify the binding standards, and the binding effect of the steel cage is better; Uniform and accurate position, the cage is flat and straight, which can effectively bind the thickness of the protective layer of steel bars and improve the service life of the road.

detailed description

In conjunction with accompanying drawing 1, the utility model is further described:

The utility model comprises: rear outrigger 1, forelimb leg 2, bracket cross bar 3, bracket vertical bar 4, bracket front oblique bar 5, horizontal support 6, upper slotted square steel tube 7, lower slotted square steel tube steel 8, front end Bottom support 9, connecting pin 10. Wherein a plurality of support front slant bars 5 on the front side, a plurality of support vertical bars 4 on the rear side and a plurality of support cross bars 3 arranged at intervals horizontally between the two form a frame support; a plurality of support front slant bars The front side composed of 5 is distributed horizontally from top to bottom with two square steel pipes (that is, upper slotted square steel tube 7, lower slotted square steel tube steel 8) and multi-layer horizontal support 6, upper slotted square steel tube 7, lower slotted square steel tube The square steel pipe steel 8 has a plurality of vertical notches at intervals along the length direction, and the vertical notches on each square steel pipe correspond to each other up and down; the width of the notch is slightly larger than the diameter of the steel bar to be bound, and the upper and lower sides The groove spacing and size of the steel pipes and the spacing of the horizontal support arrangement are made in strict accordance with the design position and spacing of the longitudinal and transverse steel bars of the box girder web; 1 and the height of the forelimb legs 2 must be less than the height of the prefabricated pedestal of the box girder; the front bottom of the frame support is provided with a horizontal front end bottom support 9, the thickness of the front end bottom support 9 is consistent with the thickness of the steel reinforcement protective layer of the bottom plate, and it also controls the box girder The effect of the thickness of the protective layer on the bottom of the board. The formwork is freely divided into sections according to the construction strength and weight requirements. The principle is to avoid deformation and facilitate manual movement. Each section is numbered in sequence and connected by connecting pins 10. At the same time, it should be noted that the notch spacing of the upper and lower slotted square steel pipes should also meet the design steel bar spacing requirements of the box girder at the segment connection.
