Detailed Description
In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Example 1:
the utility model relates to a prefabricated box girder wedge block die assembly with a variable position, which comprises a profile steel pedestal 4 arranged on a hardening field, wherein the profile steel pedestal is formed by combining two H-shaped steel; a distribution beam 3 is arranged above the end head of the section steel pedestal, the distribution beam 3 is composed of a plurality of channel steel, and the channel steel and the section steel pedestal are firmly welded; the profile steel frame 2 is arranged above the distribution beam 3, the wedge block mold 1 which can move above the profile steel frame is arranged above the profile steel frame 2, and the wedge block mold 1 is a concave steel plate mold.
Preferably, the steel frame 2 is welded into a rectangle by combining four channel steel.
Preferably, the wedge block mold 1 has a rectangular shape.
The manufacturing method comprises the following steps:
1. after the hardening of the precast beam field is finished, two H-shaped steel strips with the same length are erected above the precast beam field, the H-shaped steel strips are welded by adopting channel steel at certain intervals and then are connected into a whole, and the positions of the wing plates of the steel strips are reinforced by adopting channel steel welding at certain intervals.
2. According to the prefabricated box girders with different lengths, transverse channel steel distribution girders are arranged at proper positions of the ends of the prefabricated box girders, and the channel steel and the profile steel pedestal are firmly welded.
3. Four channel steels are welded into a rectangular steel frame, the steel frame is welded with a distribution beam at the end of the pedestal to form a whole, and the position of the steel frame can be integrally adjusted when the length of the precast beam is changed greatly.
4. The wedge block mold is manufactured according to the shape of the wedge block of the box girder, is made of steel plates, and can freely move along the longitudinal beam direction on the profile steel frame so as to be suitable for the condition of small length change of the precast beam.
5. According to the gradient of the beam bottom which can be adjusted by filling sand into the wedge-shaped block molds of different box beams, a steel plate is paved on the sand after the sand molding adjustment in the molds is completed, and the flatness of the wedge-shaped block bottom plate is ensured. The wedge block mould is internally provided with sand for adjusting the transverse slope and the longitudinal slope of the wedge block, and the wedge block mould is applicable to box girders of any transverse slope and any longitudinal slope.
6. The box girder can be prevented from deformation and damage of the pedestal and cracking of the concrete at the girder end due to the fact that the mould can slide during prefabrication and stretching of the box girder.
