Description

The overall continuous rear annealing method in mobile formwork beam face
Technical field
The present invention relates to mobile formwork to retreat construction technology, particularly a kind of overall continuous retrogressing side in mobile formwork beam face Method.
Background technology
Annealing process uses traditional method hole-specifically retreated using itself bracket mostly after self-propelled moveable formwork at present, this Traditional handicraft, which there are, to be needed to have bad luck bracket repeatedly in work progress, consolidates bracket in high-altitude repeatedly, and process conversion is frequent, construction week The shortcomings that phase is longer, and work high above the ground construction safety risk is big.
The content of the invention
It is an object of the invention to provide a kind of overall continuous rear annealing method in mobile formwork beam face, mainly solve above-mentioned existing Technical problem present in technology, it shortens mobile formwork and retreats construction period, reduces plant equipment input, saves construction cost With reduction construction safety risk.
To achieve the above object, the technical scheme is that:
A kind of overall continuous rear annealing method in mobile formwork beam face, it is characterised in that:
It is applicable the precondition of this technology:
(1)Mobile formwork structure type is voluntarily downlink movable mould frame, mobile formwork retreat scope should be multispan, it is long away from From bridge;
(2)Mobile formwork is newly-increased to retreat upper hanging beam.
It comprises the following steps:
A)Track is installed in Liang Mianshang and very heavy topmast stands position, and the retrogressing beam of lifting first falls within correct above jack Position;
B)Beam is retreated using crane auxiliary installation second, crane, which slings the second retrogressing beam, makes its joint and first retreat beam pair Together, temporary consolidation is carried out with bolt and punch;
C)Normal construction high-strength bolt, and brushing antirust paint;Traversing hanging beam and traversing jack system are installed;
D)Corresponding position is welded to connect suspension centre and horizontal jack guide plate on girder, by girder with retreating upper hanging beam Connect;
E)Upper hanging beam will be retreated at flange plate preformed hole to fix using suspension rod with traversing hanging beam anchor hole, strengthens lateral stability Property;
F)Rear cross beam is completed to be connected with girder with reference to above-mentioned installation steps;
G)After end is hung in examination, bracket is released to drawing fining twisted steel, bracket is traversing to portal;
H)Mobile formwork stamping die, whole lateral moving are molded to specified location, install longitudinal stability bar;
I)Suspension rod at all flange plate preformed holes is released, simultaneously operating retreats longitudinal pushing tow on upper hanging beam and rear cross beam track Device, mobile formwork carries out continuous retreat and walked, until completing to retreat construction.
The invention has the advantages that:
By the application of this construction technology, complete within 20 days in advance mobile formwork and retreat construction, realize and saving construction Construction speed target is accelerated while machinery, material, substantially increases efficiency of construction, while reduce the danger of work high above the ground Property.
Brief description of the drawings
Fig. 1 is horizontal General Arrangement in the present invention(Hanging beam in retrogressing).
Fig. 2 is the structural representation of traversing jack system in the present invention.
Fig. 3 is horizontal General Arrangement in the present invention(Rear cross beam).
Fig. 4 is that mobile formwork beam face integrally continuously retreats longitudinal general arrangement in the present invention.
Fig. 5 is the structural representation of longitudinal thrustor in the present invention.
Embodiment
This technology construction process is further described below in conjunction with the accompanying drawings:
A kind of overall continuous rear annealing method in mobile formwork beam face, such as Fig. 1-5, it comprises the following steps:
A)Such as Fig. 1,3 vertical positions of track 2 and jack are installed on the beam face 1 of pouring concrete beam 15, lifting the One retrogressing beam 4 falls within the top correct position of jack 3.
B)Beam 5 is retreated using crane auxiliary installation second, crane, which slings the second retrogressing beam 5, makes its joint and first retreat beam 4 alignment, temporary consolidation is carried out with bolt and punch.
C)Normal construction high-strength bolt, and brushing antirust paint;Traversing hanging beam 6 and traversing jack system are installed(Such as Fig. 2). The traversing jack system includes jack and horizontal jack guide plate 8.
D)Corresponding position is welded to connect suspension centre and horizontal jack guide plate 8 on girder 7, by girder 7 with retreating Hanging beam 9 connects.
E)Upper hanging beam 9 will be retreated at the preformed hole of flange plate 10 to fix using suspension rod 11 with the traversing anchor hole of hanging beam 6, enhancing is horizontal To stability.
F)Such as Fig. 3, rear cross beam 12 is completed to be connected with girder 7 with reference to above-mentioned installation steps, such as Fig. 4 after installation.
G)After end is hung in examination, bracket 13 is released to drawing fining twisted steel, bracket 13 is traversing to portal.
H)Mobile formwork stamping die, whole lateral moving are molded to specified location, installation longitudinal stability bar 14.
I)Suspension rod 11 at all preformed holes of flange plate 10 is released, simultaneously operating is retreated on upper hanging beam 9 and the track of rear cross beam 12 Longitudinal thrustor(Such as Fig. 5), mobile formwork carries out continuous retreat and walked, until completing to retreat construction.Longitudinal thrustor Including jack 161, traversing oil cylinder 162.
It is only presently preferred embodiments of the present invention in summary, is not used for limiting the practical range of the present invention.It is i.e. all The equivalent changes and modifications made according to the content of scope of the present invention patent, it all should be the technology category of the present invention.
