Problems solved by technology

This structure makes the internal operation space of the inner mold narrow, difficult to close the mold, time-consuming and laborious to assemble the formwork, the formwork is too complicated, too many consumables in the support part, the cost of the formwork rises, and the operation is complicated. The mold cannot be carried out synchronously, it is not stable and simple enough, and the reliability and safety are low

Embodiment Construction

[0035] Referring to Fig. 1-2 for the embodiment, this fully automatic hydraulic prefabricated box girder internal mold system has support frames 16 arranged at intervals along the depth of the box girder in the center of the bottom of the cavity formed by the inner formwork 4, and steel rails 7 are erected on the support frames. Go up the translation trolley, which includes traveling wheels 5, a vehicle frame and a support beam 9 fixed on the vehicle frame, and the frame of the translation trolley extends to the outside of the inner formwork, on which a hydraulic pump station and an operating platform 12 are placed; The frame is mainly composed of two longitudinal beams 6 and a beam 8 connected between the two longitudinal beams.

[0036] Referring to Figure 2, the right side is a schematic diagram of the internal mold shrinking state, and the left side is a schematic diagram of the internal mold expansion state.

[0037] On the jacking section: the upper inclined oil cylinder...

Abstract

The automatic hydraulic premade box beam inner formwork system has the inner mold hinging with a pair of up corner mold and a lower corner mold, oil tank slanting upward connected between the top mold and the up corner mold, oil tank slanting downward connected between the top corner mold and the lower corner mold, bracket barricaded along the box beam at the center of the cavity bottom surrounded by inner molds supporting up steel track that has translation cart along it with the cart composed of walking wheel, frame, supporting base beam fastened on the frame, frame of the cart extending outside of the inner mold plate with hydraulic pump station and operation platform. It is simple, steel consumption effective, low in cost, improving inner space 25% than the traditional one.

Description

(1) Technical field [0001] The invention relates to a formwork system of a reinforced concrete bridge, in particular to an internal formwork system of a prefabricated box girder. (2) Background technology [0002] The traditional internal formwork system of prefabricated box girder includes formwork and support. The formwork is hinged by a top formwork, a pair of upper inner corner forms and a pair of lower inner formworks. Between the moulds, the lower oblique oil cylinder is connected between the upper female corner mold and the lower female corner mold, which can make the template fold and shrink. Too much space inside the box girder is taken up. The longitudinal beam is fixed under the top mold, the slide rail is fixed under the longitudinal beam, the lower part of the mold cavity is fixed with a lifting cylinder support, and the lifting cylinder support is fixed with rollers. When the formwork is installed in the prefabricated box girder, the oil cylinder supporting t...
