Description
Technical field
The utility model is used for technical field of road construction, particularly relates to a kind of bridge concrete anticollision barrier vertical expansion joint construction system.
Background technology
Along with the fast development of China's traffic network, bridge construction technology is maked rapid progress.People while entity quality, the most increasingly pay close attention to bridge appearance aesthstic, and the anticollision barrier outward appearance as the external face-saving project of bridge are particularly important in paying attention to bridge.Linear and the expansion joint breaking joint quality of anticollision barrier is again the important evidence evaluating anticollision barrier outward appearance, and breaking joint Forming Quality is also always in anticollision barrier construction the emphasis and difficult point controlled.
3 kinds of construction methods that conventional concrete anti-collision guard bar expansion joint breaking joint is arranged:
1st kind: use plank sheathing to make expansion joint breaking joint formwork.Press from both sides at guardrail formwork edge joint one piece of thickness be the plank sheathing of 18mm as breaking joint formwork, brushing releasing agent on plank sheathing, after and form removal complete until guardrail concreting, then plank sheathing is removed, forms breaking joint.
2nd kind: use big block plate to make expansion joint breaking joint formwork.It is that the steel plate of 18mm is as breaking joint formwork at guardrail template sections edge joint position one piece of thickness of folder, the same hole of bolt eye on steel form dual-side and guardrail steel form flange, brushing releasing agent on steel plate, complete until guardrail concreting and after removing steel form, again steel breaking joint plate is removed, form breaking joint.
3rd kind: use bulk white foam plate to make expansion joint breaking joint formwork.Press from both sides at guardrail formwork edge joint one piece of thickness be the white foam plate of 18mm as breaking joint formwork, after and form removal complete until guardrail concreting, then white foam plate is plucked out, formation breaking joint.
The shortcoming of prior art:
(1) the 1st kind of shortcoming making expansion joint breaking joint formwork with plank sheathing:
(1), plank sheathing bad fixing, casting process is easily subject to concrete lateral pressure and causes tilting, especially plank sheathing both sides concrete discharging asymmetric uneven time, plank sheathing is easily toward lopsidedness, thus causes breaking joint vertical, affects outward appearance.
(2), after guardrail concrete setting, it is big that plank sheathing removes difficulty, is easily caused breaking joint limit concrete losing angle, affects outward appearance during dismounting.
(3) plank sheathing, removed all deforms seriously, it is virtually impossible to recycle and reuse, and plank sheathing usage amount is big, and cost puts into higher.A large amount of plank sheathings are affected by concrete setting, extrude tension, use usual manner to remove, and generally require and utilize cutting machine to carry out chopping dismounting, time-consuming, and environmental pollution is bigger.
(2) the 2nd kinds of shortcomings making expansion joint breaking joint formwork with big block plate:
(1), after guardrail concrete setting, it is big that difficulty removed by steel form, taps dismounting and is easily caused breaking joint limit concrete losing angle, affects outward appearance.
(2), big block plate be inherently easily deformed, the steel form removed taps due to needs, 1 all deform after twice serious, it is virtually impossible to recycling, be required for doing new, steel using amount is big, and cost input is higher.Steel breaking joint plate is affected by concrete setting, extrudes tension, uses hammering method to remove, time-consuming, and environmental pollution is bigger.
(3) the 3rd kinds of shortcomings making expansion joint breaking joint formwork with bulk white foam plate plate:
(1), white foam template is bad fixing, casting process is easily subject to concrete lateral pressure cause crushing, especially cystosepiment both sides concrete discharging asymmetric uneven time, cystosepiment is easily toward lopsidedness or break, thus cause breaking joint the most vertically or the most entirely to break, affect outward appearance and using effect.
(2), white foam plate all becomes powder after scratching and removing, it is impossible to recycling, usage amount is big.Scratch and remove into powder dismounting, time-consuming, and white powder environmental pollution is bigger.
