Abstract
A kind of cast-in-situ box girder outer steel formwork board mounting assembly corresponds to bracket stringer (1) in the template truss rod piece bottom of outer template truss (2) and is provided with pulley (3)；And remaining between the bracket stringer (1) and pulley (3) there is gap.External mold plate girder (2) is vertically moved by the pulley (3) of setting along corresponding bracket stringer (1) under the action of tractive force, without being limited by landform, effectively reduces security risk.
Description
Technical field
The utility model relates to a kind of mounting device, more specifically to a kind of cast-in-situ box girder outer steel formwork plate installation dress
It sets, belongs to science of bridge building beam body technical field of construction.
Background technique
Currently, outer steel formwork plate is all after directly removing using crane, to be transferred to adjacent holes during construction of cast-in-situ box-beam
In the bottom die platform that position has been set up.By taking across the 32.6m box beam of gauge orifice as an example, 25t is needed to hang by the template installation of 32 pieces of every hole
Che Yitai, 4 people cooperation, install 2.5 days and calculate, expense is at 7000 yuan or so；And need place more smooth, it can install safely
Crane.And AT STATION in when carrying out multiple-track bridge in-situ beam casting, the beam body of laterally adjacent two hole beams after-pouring and poured beam body
Between outer steel formwork plate it is even more impossible to using traditional crane dismantling method (no space installs crane), typically one by one with jack
It is put into ground and returns again to next cross-location and lifted, it is both dangerous or uneconomical.
Summary of the invention
The purpose of this utility model is that for existing outer steel formwork plate using the existing dangerous and uneconomical shape of lifting
The problems such as condition, provides a kind of cast-in-situ box girder outer steel formwork board mounting assembly.
To achieve the above object, the technical solution of the utility model is: a kind of cast-in-situ box girder outer steel formwork plate installation
Device corresponds to bracket stringer in the template truss rod piece bottom of outer template truss and is provided with pulley.
It is remaining between the bracket stringer and pulley to have gap.
Limiting device is provided on the bracket stringer.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model is novel, and structure is simple, economic and practical, and easy construction.
2, the utility model is compared with the installation of traditional crane, without being limited by landform；Especially when carrying out multi-thread bridge construction,
Not having using crane space, existing after-pouring box beam outboard template is very big using jack dismounting mode security risk, and
The utility model sliding movement effectively reduces security risk.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is the partial enlarged view of Fig. 1.
In figure, bracket stringer 1, external mold plate girder 2, pulley 3.
Specific embodiment
The utility model is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.
Referring to Fig. 1 to Fig. 2, a kind of cast-in-situ box girder outer steel formwork board mounting assembly is particularly suitable for porous continuous cast-in-place case
Beam forms installation；It corresponds to bracket stringer 1 in the template truss rod piece bottom of outer template truss 2 and is provided with pulley 3, in tractive force
The template for acting on lower external mold plate girder 2 is vertically moved by pulley 3 along bracket stringer 1.
It is remaining between the bracket stringer 1 and pulley 3 to have gap referring to Fig. 1 to Fig. 2.
Referring to Fig. 1 to Fig. 2, limiting device is provided on the bracket stringer 1.Limiting device can prevent from being expert at passing by
It wanders off in journey.
Referring to Fig. 1 to Fig. 2, fallen on bracket stringer 1 in beam body template demoulding rear wheel 3, bracket stringer 1 uses sliding rail as
Road.Outer steel formwork plate is walked on bracket stringer 1 with external mold plate girder 2 in the case where jack or hoist engine are pulled or pushed,
Next hole beam position is slid onto carry out in place.And between bracket stringer 1 and pulley 3 it is remaining have gap to reserve enough spaces make it is outer
Side template can be detached from beam body；And the pulley 3 in shuttering work state is made to be not involved in stress.Therefore, the utility model solves
Box girder formwork is poured at present using limitation existing for hanging method, is especially improved current multiple-track bridge cast-in-situ box girder template and is moved
Toward dangerous and uneconomical situation existing for next hole.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, above structure
It all shall be regarded as belonging to the protection scope of the utility model.
