Embodiment Construction

[0014] Template design: The male and female tenons are set on two templates at a chamfer of the inner mold, the male tenon is set on the chamfering template, the length of the male tenon is 15mm, and the female tenon is set on the large plane mold, and the depth of the female tenon is 5mm. The jacking bolts are set on the vertical frame of the female tenon formwork with a spacing of 600mm, and the jacking bolts are set between the vertical seam connecting bolts on the vertical frame of the male tenon formwork with a spacing of 400mm. The vertical frame of the two templates of the male and female tenon is installed The spacing is 10mm, and the vertical seam connection bolts at the male and female tenons are consistent with other vertical seams.

[0015] Installation: Back off the bolts to flatten the formwork surface, and stick transparent tape on the contact between the formwork surface and the bolts to prevent slurry leakage; tighten the jacking bolts and vertical seam connect...

Abstract

The invention discloses a hollow thin-walled pier internal mold bolt ejection removal technology, and relates to an internal mold. The hollow thin-walled pier internal mold bolt ejection removal technology comprises template design and a construction method; in the template design, designing a mortise and a tenon, ejection bolts and puller bolts is included, the mortise and the tenon are arranged on two templates at one chamfer of the internal mold, the mortise is arranged on a chamfer template, the tenon is arranged on a big plane mold, the ejection bolts are arranged on the vertical frame of the mortise template, and the puller bolts are arranged between vertical joint connecting bolts on the vertical frame of the tenon template; during the installation, the template surface is screwed by the ejection bolts, and the puller bolts and the vertical joint connecting bolts are screwed down; during mold removal, the connecting bolts of the tenon template are removed, the puller bolts are screwed up, and the ejection bolts are screwed down from bottom to top. The technology solves the problems that a hollow thin-walled pier internal mold is difficult to install and detach, slurry is easy to leak, materials are wasted, the template is easy to deform, the concrete is easy to knock and pry and the like, and is suitable for internal mold design and construction of engineering.

Description

technical field [0001] The invention relates to a design and construction method of an inner mold of a hollow thin-walled pier in bridge engineering, and the technology is applicable to the design and construction of the inner mold of a hollow thin-walled pier for highway, municipal, railway bridges and other bridge projects. Background technique [0002] At present, the internal formwork design of hollow thin-walled piers in domestic bridge projects adopts the method of reserving a gap on the inner formwork at one corner. There are following problems and deficiencies in this method: [0003] (1) When the formwork is installed, the gap is not easy to fix, and it is easy to be wrong and leak; after the formwork is removed, the concrete surface needs to be modified. [0004] (2) It is difficult and time-consuming to remove the formwork, and the man-hours consumed for removing the inner formwork are nearly twice that of removing the outer formwork. [0005] (3) The wooden bea...
