Description
Technical field
The invention belongs to steel box and steel casing in the water-retaining structure in the bridge bearing platform construction, be specifically related to the anchor device that is connected between a kind of steel box and the steel casing.
Background technology
The steel box is realized with the employing pull bar that is connected between the steel casing now.On the outer wall of steel casing, establish the connection that fixing bracket is used for pull bar.This structure is big at bearing capacity, when the steel box that size is big uses, can cause characteristics such as waste great deal of steel, duration.For planar dimension be: long 76.4m, wide by 41.4, high 10 meters, heavily about 1480 tons steel box, because the planar dimension of steel box is bigger, it relies on pull bar and the bracket on the steel casing on steel box base plate to form anchoring system and bears and conduct oneself with dignity and weight concrete when pouring into a mould under water bottom concrete, and when bottom concrete poured as yet not initial set, anchoring system will bear about 10000 tons pulling force.Stressed evenly for guaranteeing each position of steel box, the steel box need design 400 pull bars, numerous pull bar like this, how to realize its Fast Installation, shorten the box set-up time, reduce construction risk, make simultaneously pull bar stressed survey adjustable, guarantee that construction safety is reliable, and adopt existing structure to realize.
Summary of the invention
The object of the present invention is to provide a kind of anchor device that is connected that can be quick installed between steel box and the steel casing, to address the above problem.
Technical scheme of the present invention is: be connected anchor device between steel box and the steel casing, it comprises the steel box, steel casing in the steel box, offer the drawer hole on the steel casing body, establish support on the steel casing body inwall, can relatively move and the drawer type bracket of locating passes the drawer hole and is bearing in support at support; Supporting arrangement is established in steel box bottom, cylinder lever connecting rod on the supporting arrangement device, and the other end of pull bar is connected with drawer type bracket on the steel casing body.
Described support comprises bottom bracket and the upper limit reaction frame that is connected with steel casing body inwall, establishes the guide and limit frame on the bottom bracket; Upper limit reaction frame and bottom bracket adopt steel plate to be connected, and the drawer type bracket is located in the guide and limit frame on the bottom plate, and drawer type bracket top contacts with confinement plate.
Described pull bar comprises upper connecting rod, is connected by connector between the lower link, upper connecting rod and lower link.
The supporting arrangement of described steel box bottom comprises hinged bearing, the hinged support hinged-support that is articulated and connected, and pull bar is connected with hinged-support.
Pull bar adopts the smart indented bars of pricking.
Anchor device between steel box of the present invention and the steel casing
This patent adopts scalable drawer type bracket and smart pricks the use that matches of indented bars pull bar, has realized the purpose of steel box pull bar Fast Installation; Smart prick that indented bars is stressed can be measured and adjust by torque wrench or jack, make pull bar stressed more even, guarantee construction safety; Scalable bracket and anchor device can have enough to meet the need use.With Shanghai Yangtze Bridge master bridge bid section is example, and six bridge piers only beginning to have processed 400 covers, forward whole constructions always week to and finish, and have saved nearly 200 tons of materials.Smart prick the indented bars pull bar and have the intensity height, from heavy and light, the little and flexible big characteristics of distortion, characteristic with stronger adaptation base plate pull bar and steel casing anchor point deviation, and be 1/4 of plain edition reinforcing pull rod weight, both reduced difficulty of construction, alleviated the deadweight of pull bar and steel box again, simultaneously, the bottom concrete end face can have enough to meet the need use, economical with materials with the top pull bar.
