During embody rule, by the bracing means of application GRC non-dismantling formwork 3 as the concrete component 1 of the odd-shaped cross section of permanent alien invasion in the utility model, comprising the bracing means to steel concrete arch post, described steel concrete arch post is the concrete arch springing of the main steel arch pipe of layer Steel Structure, be hexagonal reinforced concrete arch frame beam lateral connection by cross section between counterfort and counterfort, the crossed node place of counterfort and arch frame beam, there is one to encircle frame post as oblique support column, support oblique counterfort.
Counterfort is not merely longitudinal have radian, laterally also there is angle of inclination; One group of counterfort to be two cross sections be hexagonal steel concrete counterfort is close, crossing, the moulding that is separated slowly, is not hexagon crest line simple intersection in intersection, but has done phase top-stitching and relax process; Arch frame beam is regular hexagon reinforced concrete beam, and the moulded of arch frame post playing skewed horizontal load effect has two kinds, and be respectively " X " shape and " Y " shape, bottom is dropped on frame post cushion cap, upper support one group of counterfort; Steel concrete counterfort, arch frame post and arch frame beam are and expose component, and according to designing requirement, visual concrete component is clear-water concrete effect.
For ensureing superior making and the clear-water concrete effect of odd-shaped cross section counterfort, alien invasion adopt GRC material to do template is double does clear water outside finish; Bury pre-buried ring 4 underground in described GRC non-dismantling formwork 3, fixed by the reinforcing bar of itself and counterfort, arch frame post and arch frame beam are position, indoor and outdoors boundary, and insulation is built in GRC non-dismantling formwork 3; The regular hexagonal section length of side of counterfort is 981mm, and the regular hexagonal section length of side of arch frame beam is 841mm, and cross section is comparatively large, and outside uses reinforcing tie of the present utility model effectively to reinforce, and ensures quality and the safety of concreting.
A kind of GRC of application material that the utility model embodiment proposes is further improvement of existing technologies as the construction method of the bracing means of the deformed bar concrete component of facing non-dismantling formwork, and concrete improvement is as follows:
1) solve Screw arbor with nut at both-ends reinforcing and can not lead to the problem of wearing, perforate when avoiding GRC formwork reinforcement destroys, and ensure that perfect alien invasion effect;
Enclose hoop outside service-strong, in outside, secondary joist 5 is surrounded, thus by formwork reinforcement, solve the problem that Screw arbor with nut at both-ends can not be used to reinforce.
2) the reinforcing integrity problem of the special-shaped heavy in section reinforced concrete member 1 adopting GRC non-dismantling formwork 3 is solved;
By the large i iron of rigidity as main joist 6, and use bolt 7 to screw connection, ensure that reinforcing reliability, guarantee quality and the safety of concreting.
3) solve later stage repairing and pick the time-consuming problem of cutter;
In order to ensure the clear-water concrete effect of alien invasion, taking reliable reinforcement measure during reinforcing, avoiding in casting process the problem such as mould, spillage that rises, one-shot forming, cutter is picked in the repairing reducing the later stage, also ensure that good appearance effect.
The main beneficial effect that the utility model brings is as follows:
One, quality and benifit
The emphasis optimized solves not by adopting the reinforcing problem of the special-shaped heavy in section concrete component 1 of GRC non-dismantling formwork 3, and guarantee strengthening quality, the Be very effective after optimization, makes a concrete analysis of as follows:
1) changing reinforcing mode, providing effective Scheme of Strengthening of the special-shaped heavy in section concrete component by adopting GRC non-dismantling formwork 3, make to become possibility to the reinforcing of the special-shaped heavy in section concrete component 1 adopting GRC non-dismantling formwork 3;
2) the peripheral i iron of service-strong closes hoop, is surrounded by secondary joist 5, thus by formwork reinforcement, avoid the destruction of clear-water concrete effect alien invasion effect in outside;
3) i iron taking rigidity large when reinforcing also by the reliable reinforcement measure that bolt 7 connects, avoids in casting process the problem such as mould, spillage that rises, one-shot forming, and cutter is picked in the repairing reducing the later stage.
Two, social benefit
1) in the quality policy of " project of vital and lasting importance; quality first ", guarantee that workmanship is the most important thing of engineering construction, and be the effective reinforcing in order to the special-shaped heavy in section concrete component 1 to employing GRC non-dismantling formwork 3 for the emphasis optimized, thus ensure the pouring quality of concrete component 1, be the attitude that engineering is responsible for;
2) in the people's livelihood engineering of Government-Leading, under the severe situation that duration tight task is heavy, how to guarantee both quality and quantity, pay and safe coming into operation on time, being that we cash the most basic content of contract promise, is also the social responsibility that building people must have; The reinforcement measure of this project to the special-shaped heavy in section concrete component 1 adopting GRC non-dismantling formwork 3 is improved, ensure that the topmost concrete component of station (counterfort, arch frame post and arch frame beam) one-shot forming smoothly, avoid secondary to pick cutter to repair, beautiful appearance, Fast Practical;
3) optimization of special-shaped heavy in section concrete component 1 reinforcement measure of GRC non-dismantling formwork 3 is adopted also to have popularizing action, the design pursuing the clear-water concrete effect of nature honesty becomes more and more popular, the moulding of modern architecture is also more and more diversified, the reinforced concrete structure of odd-shaped cross section also can get more and more, similar construction method can be adopted to construct, to meet the needs of duration, quality, environmental protection and saving material.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
