Integral disassembly box girder internal mold and use method thereof

Abstract

The invention relates to an integral disassembly box girder internal mold. The internal mold comprises support end molds and mid-span molds, wherein the support end molds are arranged on the end parts of the two ends of a box girder; the mid-span molds are arranged on the middle part of the box girder; a plurality of mid-span molds are spliced together; flange plates of adjacent mid-span molds stick close to each other, and are connected together through flange bolts; the support end molds are connected to the two ends through flange bolts respectively. In an integral disassembly method for the internal mold during box girder machining, a fixed support and a lower compensating plate are removed firstly during integral disassembly, a hoist tensions a pull rod to bend a brace, and an inverted-L-shaped structure and an L-shaped structure are enclosed around a hinge to be separated from the inner cavity of the box girder so as to be pulled out after being contracted. By adopting the internal mold and the use method thereof, integral demolding can be realized; moreover, the quantity of molds can be increased according to the actual length of the box girder, so that convenience and rapidness in use are realized.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an inner mold used in the processing of box girders, which can realize integral disassembly of living bodies. Background technique [0002] Box girders are mostly used in projects such as roads and bridges, and are required to reach a certain strength due to the limitations of geographical and terrain conditions. Different types of box girders are designed to meet the strength requirements. The forming of the inner mold depends on the inner mold. The height of the box girder is usually greater than 1 meter. The height of the inner mold is relatively small, and the space inside the mold is small, which makes it more difficult to manually enter the mold during installation and removal. Therefore, It is envisaged that the overall easy installation and removal can save production and construction time and reduce labor costs. [0003] The utility model with the patent number 2015...

Problems solved by technology

During the use of the above-mentioned prior art, it is inconvenient to connect the self-demolition inner mold in the production of larger box girders, and there are seams at the connection parts, resulting in small defects in quality, and the gaps in the connection between the left and right shells inside also affect the quality. quality
