Abstract
The invention discloses a minimal-interval separation type thin-wall pier formwork and application thereof. The minimal-interval separation type thin-wall pier formwork is characterized in that two V-shaped formworks are arranged, and in each V-shaped formwork, one ends of two flat plate steel dies are connected through a hinge to form the hinge end of a V shape, and the other ends of the two flat plate steel dies are separated from each other to form the opening end of the V shape; the two V-shaped formworks are fixedly connected in the manner that the hinge ends of the V-shaped formworks are inserted and located on the center line of a thin-wall pier and the opening ends of the two V-shaped formworks face openings in the two side edges of the thin-wall pier; and in addition, two end formworks and two side formworks are connected to form a rectangular frame to serve as an outer frame formwork of the thin-wall pier and the two end formworks and the opening ends of the two V-shaped formworks are correspondingly connected to form two independent die cavities of the thin-wall pier. The minimal-interval separation type thin-wall pier formwork is applied to construction of the minimal-interval separation type thin-wall pier, the engineering quality can be effectively guaranteed, and the construction schedule can be effectively accelerated.
Description
Technical field
The present invention relates to Thin-Wall Piers template and application thereof, be more particularly a kind of be applied in minimum spacing separate type Thin-Wall Piers construction in template and application.
Background technology
In existing technology, for eliminating the stress that continuous rigid frame produces, usually bearing is set in abutment pier position, but in recent years along with metropolis is fast-developing, subway planning extends to city suburbs, and city is focused on especially to Bridge Landscapeization, soft and graceful works is subject to the favor of builder, and flexible Thin-Wall Piers exactly meets this feature, simultaneously because subway overhead line road is long, connection number is many, structure need meet the reasons such as longitudinal strain, and separated flexible Thin-Wall Piers is widely used.Such as, Guangzhou Underground No. 21 line construction 19 marks, resemble between clock elevated region and adopt multi-joint continuous rigid frame, in order to the length travel under satisfied temperature effect, abutment pier have employed the minimum separated flexible Thin-Wall Piers being only 10cm of spacing, and it is novel in design.So-called minimum spacing separate type Thin-Wall Piers refers between two panels Thin-Wall Piers, and the minimum spacing being in center position is only about 10cm, and, between two panels Thin-Wall Piers, distinguish V-shaped opening from center position towards both sides.For this Thin-Wall Piers structure, do not have supporting construction formwork in prior art, meanwhile, because of its minimum spacing, the template of conventionally form cannot accurately put in place.Although can to the separately construction of two panels Thin-Wall Piers, such mode long construction period, progress be slow.
Summary of the invention
The present invention is the deficiency for avoiding existing for above-mentioned prior art, provides a kind of minimum spacing separate type Thin-Wall Piers template and application thereof, enables minimum spacing separate type Thin-Wall Piers be able to smooth construction, and ensures workmanship.
The present invention is that technical solution problem adopts following technical scheme:
