Construction method of high formwork with arc-shaped structure

Abstract

The invention discloses a construction method of a high formwork with an arc-shaped structure. The construction method comprises the following steps that A, a formwork with an arc-shaped structure ismade, wherein the formwork comprises side formworks and a bottom formwork, the side formworks and the bottom formwork are equally divided into standard modules and non-standard modules, and each standard module and each non-standard module are numbered; B, data analysis and setting-out positioning are performed according to measuring datum points and a design drawing; C, formwork frames of a highformwork are arranged according to a setting-out result, vertical rods of the formwork frame are arranged along the positions of beam columns to be cast, the separating distances of the vertical rodsare adjusted towards slabs to be cast, transverse rods are arranged to connect the vertical rods to form a whole, a supporting system is formed, the formwork blocks corresponding to numbers are installed and reinforced at the positions of the beam columns to be cast according to the design; D, concrete is poured, curing and formation are performed, and the formwork is removed. By applying the method, the vertical rod adjustment difficulty is reduced, the use number of the formwork frames is decreased, the installing process is simplified, the construction progress is accelerated, the construction cost is greatly reduced, part of obliquely-crossed transverse rods are directly and vertically supported on the formwork, and a support stabilization effect is good.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for arc-shaped high-support formwork. Background technique [0002] With the continuous pursuit of perfect architectural form and visual effect by architectural designers, the rigid facade design in the past has been replaced by more and more flexible and special-shaped designs, and structural forms such as circles, ovals, and arcs are widely used. In all kinds of buildings, the continuous emergence of various forms of curved beams and special-shaped panels has brought certain difficulties to its construction. Most of the existing arc structures are steel structures, and concrete arc structures require formwork, and changes in the cross section of the arc structure, changes in the overall appearance, and requirements for surface clear water effects will all affect the steel bars and formwork. The difficulty of processing and installation is increased, e...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the difficulty in construction of the arc-shaped structure with a support height of more than 8 meters in the prior art, and the formwork frames are mostly arranged orthogonally. In addition to the stable support system of the vertical horizontal bars, Additional formwork vertical rails are required at the position of beams and columns. The adjustment of the formwork vertical rods is relatively large, the number of uses is large, the installation is cumbersome, and the construction time is long. It is difficult for the formwork vertical rails to form an integral formwork frame with the orthogonal vertical rails. The above shortcomings of the system for effectively and stably supporting the formwork provide a construction method for arc-shaped structures with high support formwork
