Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] With reference to the accompanying drawings, a method for manufacturing a steel formwork for a conical end concrete pier of the present invention is aimed at a formwork used for a very large bridge pier with conical ends at both ends. Figure 1-3 Shown is a segmented formwork for the pier, which looks like figure 1 , figure 2 Shown is a pyramidal structure. combine image 3 As shown, the two ends of the pier are conical structures. The steel formwork used for pouring the integral bridge pier is composed of several segmented formworks, and the height of each segmented formwork is determined by the width of the given steel coil material. structured as Figure 1-3 As shown, the middle section of the template is composed of a rectangular plate, and the two ends of the template are half (1 / 2) conical ends. For the convenience of production, each end is divide...

Abstract

The invention relates to a method for manufacturing a steel pattern plate of a taper-end concrete pier. The method comprises the following steps: calculating circular arc points based on design parameters and marking on a plate, using a flame cutting machine to adjust the curvature radius of the track at the marked cutting points and fixing the track, then cutting the taper-end preliminarily-cut plate into fan-shaped pattern plates, welding the fan-shaped pattern plates two by two to obtain two semi-taper pattern plates, and welding and shaping the straight rectangular plate and the semi-taper pattern plates to obtain a sectional pattern plate. By using the method for making a steel pattern plate of a taper-end concrete pier and a simple tool, a large taper-end steel pattern plate, which can only be finished under specified conditions, can be manufactured and finished under primitive conditions on the construction site; and the pattern plate can be conveniently installed, tightly affixed and quickly erected, thereby ensuring construction quality and speed and completely meeting the construction requirements of piers of such big special shapes. Besides, the pattern plate has the advantages of low manufacturing cost, simple process and significant construction cost saving.

Description

technical field [0001] The invention relates to a method for manufacturing a construction formwork for a concrete bridge pier, in particular to a method for manufacturing a steel formwork for a conical concrete bridge pier construction site. Background technique [0002] At present, various large or super large concrete pier projects are often encountered in the construction of railways, highways and other projects. Many piers are designed with a conical end shape, that is, the cross-section of the pier gradually becomes smaller from the bottom to the top, and the cross-section of the pier is straight on both sides and arc-shaped at both ends. Under the existing technical conditions, the construction of this bridge pier is to make the steel formwork first, then the steel formwork is assembled and welded on site and then cast. The usual practice is to make steel formwork with special equipment at the base and then transport it to the site for assembly. Since construction sit...
