Abstract

The utility model relates to a template for construction, and particularly relates to an inner die of a box girder. The inner die of the box girder comprises a flat and straight top die, a flat and straight bottom die, a left supporting board, a right supporting board, a left inner die with a C-shaped vertical cross section, and a right inner die symmetrical with the left inner die. The inner die of the box girder provided by the utility model has the advantages of novel structure, rapidness and great convenience in mounting and dismounting, time-saving property and labor-saving conservation; the construction period can be shortened; and meanwhile, the benefits brought about to production enterprises can be improved.

Description

A kind of box girder inner formwork
Technical field
The utility model relates to the construction template, specifically a kind of box girder inner formwork.
Background technology
At present, used box girder inner formwork is to adopt single box structure in the architectural engineering, is provided with dividing plate in case on every side, but in the internal mold demolishing process, because the restriction of case inner height will all split into fritter with internal mold, could in the beam body, shift out after the disintegration, waste time and energy, also reduce operating efficiency simultaneously.
Summary of the invention
The utility model aims to provide a kind of box girder inner formwork of being convenient to assembly and disassembly.
The utility model is achieved through the following technical solutions: a kind of box girder inner formwork, comprise straight backform, straight bed die, the left support plate, the right support plate, the longitudinal cross-section is the left inside mould of " C " shape, the right inside mould symmetrical with left inside mould, described left inside mould is comprised of upper left chamfering mould and lower-left chamfering mould, right inside mould is comprised of upper right chamfering mould and bottom right chamfering mould, described upper left chamfering mould bottom is articulated in lower-left chamfering die tip, and the up and down two ends of left support plate respectively bolt are connected on the madial wall of upper left chamfering mould and lower-left chamfering mould, and the straight line parallel at the sidewall place of upper left chamfering mould and lower-left chamfering mould is in the left support plate; Upper right chamfering mould bottom is articulated in bottom right chamfering die tip, and the up and down two ends of right support plate respectively bolt are connected on the madial wall of upper right chamfering mould and bottom right chamfering mould, and the straight line parallel at the sidewall place of upper right chamfering mould and bottom right chamfering mould is in the right support plate; The two ends, the left and right sides of described straight backform respectively bolt are connected in upper left chamfering mould and upper right chamfering mould inwall end face, and the two ends, the left and right sides of straight bed die are erected on respectively lower-left chamfering mould and chamfering mould inwall bottom surface, bottom right.
Before the casting concrete case beam, set up box girder inner formwork and case beam external mold, after the concrete typing, remove box girder inner formwork and case beam external mold.When removing box girder inner formwork described in the utility model, extract straight bed die out, remove the bolt on straight backform, left support plate, the right support plate, upper left chamfering mould, upper right chamfering mould are all inside, folding downwards, reduce the height of upper left chamfering mould, upper right chamfering mould, then use hoist engine that left inside mould and right inside mould are shifted out, can realize the fast demoulding of case beam.
The utility model novel structure loads and unloads very conveniently, quick, time saving and energy saving, has not only shortened the duration, also is manufacturing enterprise's additional income simultaneously.
Description of drawings
Fig. 1 is the structural representation of a kind of box girder inner formwork described in the utility model.
Among the figure: the straight backform of 1-, the straight bed die of 2-, the upper left chamfering mould of 3-, the upper right chamfering mould of 4-, 5-lower-left chamfering mould, 6-bottom right chamfering mould, 7-left support plate, 8-right support plate.
The specific embodiment
A kind of box girder inner formwork, comprise straight backform 1, straight bed die 2, left support plate 7, right support plate 8, the longitudinal cross-section is the left inside mould of " C " shape, the right inside mould symmetrical with left inside mould, described left inside mould is comprised of upper left chamfering mould 3 and lower-left chamfering mould 5, right inside mould is comprised of upper right chamfering mould 4 and bottom right chamfering mould 6, described upper left chamfering mould 3 bottoms are articulated in chamfering mould 5 tops, lower-left, and the up and down two ends of left support plate 7 respectively bolt are connected on the madial wall of upper left chamfering mould 3 and lower-left chamfering mould 5, and the straight line parallel at the sidewall place of upper left chamfering mould 3 and lower-left chamfering mould 5 is in left support plate 7; Upper right chamfering mould 4 bottoms are articulated in chamfering mould 6 tops, bottom right, the up and down two ends of right support plate 8 respectively bolt are connected on the madial wall of upper right chamfering mould 4 and bottom right chamfering mould 6, and the straight line parallel at the sidewall place of upper right chamfering mould 4 and bottom right chamfering mould 6 is in right support plate 8; The two ends, the left and right sides of described straight backform 1 respectively bolt are connected in upper left chamfering mould 3 and upper right chamfering mould 4 inwall end faces, and the two ends, the left and right sides of straight bed die 2 are erected on respectively lower-left chamfering mould 5 and bottom right chamfering mould 6 inwall bottom surfaces.
