Step:
S1, hoop component 1 is installed on pier stud；
Adjustable jacking is set on S2, hoop component 1, I-steel 21 is installed on jacking, the I-steel 21 is parallel
Setting, by connecting channel steel to wearing pull rod is positioned I-steel 21 after installation；
S3, several A-frames 31 of 21 outside grafting of I-steel are simultaneously bolted, 31 upper berth of A-frame
If walking plate 32 is simultaneously positioned, A-frame 31 is equipped with connecting plate, at least provided with two pivot pins on the connecting plate,
Guardrail 33 is installed on pivot pin and is tested；
S4, installation template component；
S5, concreting；
S6, demoulding.
It further include being checked and accepted to material installation tissue of marching into the arena before S1.The part of appliance of anchor ear, girder and operating platform by
Factory process molding, transports to building-site and carries out an acceptance inspection, installed after meeting the requirements, and fills hoop component 1 in step s 2,
It need to determine that anchor ear is single or multiple rows of quantity according to bent cap and upper part load-bearing load, adjustment anchor ear position makes its support when installation
Point is located at the column two sides of bridge longitudinal direction, convenient for shelving I-steel 21.
Installation template component specifically includes:
Place the longitudinal and transverse beam of bed die.After operation platform is completed, longitudinal and transverse beam is placed on girder, adjusts beam absolute altitude in length and breadth, as
It is laid with the datum level of bent cap bed die.
Bent cap bed die, bottom end mould are installed.In length and breadth after the completion of beam Pass line adjustment, bent cap bed die and lid can be laid on crossbeam
The oblique end bed die at beam both ends, it is easy to adjust.
Rotary ligating cover beam steel.After completing bed die laying, rotary ligating cover beam steel.Bent cap reinforcing bar can also be bound in advance on the ground
Good, becoming framework of steel reinforcement is integrally lifted, and to complete the binding work of framework of steel reinforcement, is built more quickly.
Bent cap side form, side mould are installed.Framework of steel reinforcement is installed and through after the assay was approved, in the peace for carrying out bent cap side form
Dress wants whether reasonable, framework of steel reinforcement the geometric dimension of detailed inspection cushion block of concrete bar protective layer setting before bent cap side form installation
Whether technical requirements are met, and indices examine qualification to carry out vertical side form again, construction can be made more to refine, Quality Cost is more
It is high.
It is poured bent cap concrete.Template installation terminates to inspect for acceptance again, the pourable concrete in the rear that meets the requirements.It is mixed
One-pass molding is wanted in solidifying soil casting, and requires to construct according to job specfication, technical standard.
Finally carry out demoulding, quality inspection.It is conserved as requested, demoulding can be carried out by reaching regulation striking time, be torn open
Continue after the completion of mould maintenance reach design, code requirement strength criterion until.
The integral construction platform is set up using bridge pier column, it can not be by terrain environments conditions such as river place, pier stud height
Limitation, meet energy-saving and environmental protection requirement, and be equipped with platform assembly 3 in 2 two sides of beam assembly, the work of safety and comfort be provided
Industry environment reduces construction worker's labor intensity, improves work efficiency, construction cost is saved, since there are platform assemblies 3 to put down
Platform component 3 is easy to control quality and safety, greatly improves the fining degree of construction.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
