Simple and accurate manufacturing method of arc edge sealing formwork

Abstract

The invention discloses a simple and accurate manufacturing method of an arc edge sealing formwork. The simple and accurate manufacturing method comprises the following steps: S1, surveying and setting out, specifically, calculating the position of the vertex of a tangent plane at the top of a channel according to a beveling angle. According to the method, firstly, two diagonal plane arch foot angular points and vertex positions of a diagonal plane arc line of a vault channel are calculated through a mathematical method, the diagonal plane arc line is set out by adopting a flexible line fixed-point veneering setting-out method, curve coincidence and shaping are conducted by using thinner steel bars according to the arc line position, a steel wire mesh or a wood formwork is installed by using the shaped steel bars as a framework, a triangular steel bar support is used as a fixing measure for the inclination angle of the formwork and is welded to the framework, and then the arc edge sealing formwork can be manufactured; and vertical keels of the edge sealing formwork are movably connected, namely short steel bars are adopted, a steel bar framework can be bent in the planes of the three dimensions of X\Y\Z, and the edge sealing formwork is suitable for erecting edge formworks of arc-curved structures such as irregular arc sections and arc-shaped steps.

Description

technical field [0001] The invention relates to the technical field of arch passage construction, in particular to a simple and accurate manufacturing method of a curved edge-sealing formwork. Background technique [0002] Vaulted passage building: It is often used for pedestrians, underground passages for traffic or artistic building corridors. The internal roof of the building is arched and circular. [0003] At present, the design of vault passages is more common in projects such as artistic buildings, underground buildings, and tunnel entrances and exits. There are two types of entrances and exits: vertical and oblique. Usually, one-time construction is used to approximately fit the oblique section, and then the surface is repaired by masonry and plastering for the second time to form a smooth oblique section. The quality of the oblique section is poor, especially the durability of the masonry layer is poor, and quality problems such as water seepage and fracture often o...

[0003] At present, the design of vault passages is more common in projects such as artistic buildings, underground buildings, and tunnel entrances and exits. There are two types of entrances and exits: vertical and oblique. Usually, one-time construction is used to approximately fit the oblique section, and then the surface is repaired by masonry and plastering for the second time to form a smooth oblique section. The quality of the oblique section is poor, especially the durability of the masonry layer is poor, and quality problems such as water seepage and fracture often occur and maintenance costs are high. In addition, curved steps are also common in outdoor projects in schools and squares. At present, masonry and pouring methods are used, which have low masonry strength, poor durability, and long maintenance cycles; Use one curve fitting, multiple straight lines instead of curves, and then mortar plastering to complete the curved surface step construction, which is wasteful of labor, poor in quality, poor in curvature and unsightly, and subsequent plastering or decorative layers Locally too thick, easy to crack and fall off
