Abstract
The utility model provides a turnover formwork construction device, and relates to a building concrete curved-surface forming construction device. A curved-surface formwork is connected with pluralities of supporting strips and provided with steel tube sample shelf, the steel tube sample shelf and the curved-surface formwork are connected with pluralities of tension bars, and a plastering platform is disposed above the steel tube sample shelf and connected with the same. By means of setting up the plastering platform on the curved-surface formwork and matching the easily detached curved-surface formwork, the steel tube sample shelf and the tension bars, the circular-arc formwork and the steel tube sample shelf are conveniently sequentially detached to plaster when concrete is nearly pre-hardened and has certain strength, thereby being capable of guaranteeing form and appearance quality of curve-surfaced concrete. In addition, the turnover formwork construction device is extremely suitable for tunnel lining with severe requirements to concrete surfaces, such as derivation tunnels, tailrace tunnels and the like of hydropower stations.
Description
Technical field
The utility model relates to a kind of building concrete curved surface forming construction equipment, particularly a kind of over-form construction device.
Background technology
It is in old concrete face mounting template that present curved surface is built, concreting then, concreting is finished and is reached stripping construction equipment after certain length of time, but mass defects such as bubble is many, faulting of slab ends, sand line appear in concrete surface that this only master plate is built easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of over-form construction device, can guarantee to build the concrete surface that finishes and not have mass defects such as bubble, faulting of slab ends and sand line, reduces later stage concrete surface work of treatment amount, guarantees Surface Quality of Concrete.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of over-form construction device, and circular formwork is connected with many support bars, and circular formwork is provided with steel pipe sample frame, and steel pipe sample frame is connected with many tie rods with circular formwork; Steel pipe sample frame top is provided with the platform of wiping one's face, and the platform of wiping one's face is connected with steel pipe frame.
Described circular formwork is provided with elongated feed opening and interval feed opening.
In the described tie rod, dowel is connected with sleeve bolt.
A kind of over-form construction device that the utility model provides, set up the platform of wiping one's face by adopting on the circular formwork, and cooperate easily detachable circular formwork, steel pipe sample frame and tie rod, can be easily remove the construction of wiping one's face of circle curve template and steel pipe sample frame successively near initial set and when certain intensity is arranged, thereby can guarantee concrete build of curved surface and curved surface Surface Quality of Concrete at concrete.Be fit to very much the tunnel lining strict, for example diversion tunnel in power station, tailwater tunnel etc. to concrete surface.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples: Fig. 1 is a structural representation of the present utility model.
The specific embodiment
In Fig. 1, a kind of over-form construction device, circular formwork 2 is connected with many support bars 6, and circular formwork 2 is provided with steel pipe sample frame 4, and steel pipe sample frame 4 is connected with many tie rods 8 with circular formwork 2; Circular formwork 2 and steel pipe sample frame 4 can be dismantled easily.
