The present invention uses the method for the prestress concrete box girder of hanging basket formwork making band sightseeing walkway board, including: (1) makes hanging basket formwork side form；(2) sightseeing walkway board template and support are made；(3) sightseeing walkway board template adjusts and fixes after each parts of hanging basket formwork are adjusted in place, and on the operating platform of Hanging Basket side, by regulation adjustable jack, the regulation of sightseeing walkway board form height is put in place, and template is locked with Hanging Basket bed die, mortar leakage prevention；(4) pour sightseeing walkway board concrete and box beam each position concrete: (5) demoulding: (6) walk: during hanging basket formwork walking, the forward and backward sill of Hanging Basket drive sightseeing walkway board template to run to next section of pouring, the same step of formwork erection method (1)～(5) together.The present invention goes sightseeing, and walkway board template is vertical, form removal is convenient, flexible adjustment, saves human and material resources, and efficiency of construction is high.
Description
Technical field:
The present invention relates to road and bridge construction field, particularly relate to a kind of method that prestress concrete box girder using hanging basket formwork to make band sightseeing walkway board is once constructed.
Background technology:
In current domestic science of bridge building, the structure being provided with sightseeing walkway board in prestressing force solidifying soil continuous beam side is the rarest, if light sees walkway board structure and main tank beam pouring construction simultaneously, hanging basket formwork side side form formwork erection will be there is and found the problems such as form removal difficulty by the interference of sightseeing walkway board, sightseeing walkway board template.
Summary of the invention:
The invention aims to overcome hanging basket formwork side side form formwork erection to be found the problems such as form removal difficulty by the interference of sightseeing walkway board, sightseeing walkway board template, a kind of sightseeing walkway board template of offer is vertical, form removal is convenient, flexible adjustment, using manpower and material resources sparingly, the prestress concrete box girder of the band sightseeing walkway board that efficiency of construction is high uses the method that Hanging Basket is once constructed.
The present invention purpose be achieved like this:
The present invention uses the method for the prestress concrete box girder of hanging basket formwork side form making sightseeing walkway board, comprises the following steps:
1) hanging basket formwork side form is made:
By making the hanging basket formwork side form being made up of the template of some joint detachables on the form height direction, hanging basket formwork side of sightseeing walkway board, merogenesis height is that adjacent to pour segmental height poor for precast beam, because box beam height is gradually lowered from 0# BOB(beginning of block), the effective usable floor area of Hanging Basket side form is also gradually decreasing, wherein on one side side form can the most cantilevered out bed die, and opposite side template is disturbed by sightseeing walkway board, it is impossible to cantilevered out Hanging Basket bed die, it has to be possible to advance along with sections and remove section by section；
(2) sightseeing walkway board template and support are made:
Forward and backward sill at hanging basket formwork has the side of sightseeing walkway board template to set up two longerons, and longeron uses pin joint mode with the forward and backward sill of Hanging Basket, it is simple to longeron carries out nature angle adjustment with bed die change；At least three adjustable jack is installed on every longeron, while supporting sightseeing walkway board template, template is adjusted in place；
(3) sightseeing walkway board template adjusts and fixing:
After each parts of hanging basket formwork are adjusted in place, on the operating platform of Hanging Basket side, by regulation adjustable jack, the regulation of sightseeing walkway board form height is put in place, and template is locked with Hanging Basket bed die, mortar leakage prevention；
(4) sightseeing walkway board concrete and box beam each position concrete are poured；
(5) demoulding:
After concrete arrives certain age, should first remove sightseeing walkway board template to retrain with end template, again by adjustable jack by below the sightseeing walkway board template demoulding to concrete face 4.5～5.5cm, then the demoulding of hanging basket formwork is carried out, form removable one joint of sightseeing walkway board side first will be had before the hanging basket formwork demoulding, carry out the conventional demoulding of Hanging Basket, the same conventional method of the hanging basket formwork remaining part demoulding again, repeat no more here；
(6) walking: during hanging basket formwork walking, is driven sightseeing walkway board template to run to next section of pouring, the same step of formwork erection method (1)～(5) together by the forward and backward sill of Hanging Basket.
The inventive method by carrying out local particular design by routine hanging basket formwork, and by sightseeing walkway board shuttering supporting on the forward and backward sill of Hanging Basket, sightseeing walkway board template is vertical, form removal is convenient, flexible adjustment, and can realize and hanging basket formwork synchronous walking, saving construction human and material resources, construction effect is high.

Detailed description of the invention:
Prestress concrete box girder 2 structure of band sightseeing walkway board 1 is shown in Fig. 1, Fig. 2.Pouring with box beam 2 main body to realize sightseeing walkway board 1, the present embodiment uses hanging basket formwork to make construction method of prestress concrete box girder of band sightseeing walkway board, comprises the steps: simultaneously
(1) some for hanging basket formwork side form 7 points restrainings are made:
Seeing Fig. 3, Fig. 4, Fig. 5, the side form 7 of hanging basket formwork is being made up of some joints by the form height direction, side of sightseeing walkway board, and merogenesis height is that adjacent to pour segmental height poor for precast beam；In Fig. 4, sequence number 71,72,73,74,75,76 is respectively first segment template, second section template, Section of three template, Section of four template, Section of five template, Section of six template；
(2) sightseeing walkway board template 6 formwork erection:
Seeing Fig. 6, Fig. 7, front sill 2 and rear sill 3 at hanging basket formwork have the side of sightseeing walkway board to set up two longerons welded respectively 4 by channel-section steel.Longeron 4 uses pin joint mode with the forward and backward sill of Hanging Basket, it is simple to longeron 4 carries out nature angle adjustment with bed die change；Three (or four) individual adjustable jack 5 is had to be used for supporting sightseeing walkway board template 6 on every longeron 4.Sightseeing walkway board template 6 is designed to the steel form that shapes；
(3) sightseeing walkway board template 6 adjusts and fixing:
After each parts of hanging basket formwork are adjusted in place, on the operating platform of Hanging Basket side, by regulation adjustable jack 5, sightseeing walkway board template 6 altitude mixture control is put in place, and template is locked with Hanging Basket bed die gib headed bolt 8, mortar leakage prevention；
(4) sightseeing walkway board concrete and box beam each position concrete of box beam 1# block (0# block has poured by other template and finished) are poured；
(5) demoulding；
After concrete reaches certain age, should first remove sightseeing walkway board template 6 and retrain gib headed bolt 8 with end template, again by regulation adjustable jack 5 by about about 5cm below sightseeing walkway board template stamping die to concrete face, then the second layer template of side form 7 is removed, and ground floor template is connected with third layer template, it is last by existing conventional method demoulding Hanging Basket remaining part that the rest may be inferred；
(6) walking:
During hanging basket formwork walking, run to the 2# section of pouring with sightseeing walkway board template 6, the most repeatedly.
Above-described embodiment is that the foregoing to the present invention is described further, but this should not being interpreted as, the scope of the above-mentioned theme of the present invention is only limitted to above-described embodiment.All technology realized based on foregoing belong to protection scope of the present invention.
