Abstract

The invention discloses a template structure and a method for template support of a cast-in-place concrete arc-shaped terrace. The template structure comprises a template support frame body and a template fixing system, wherein the template fixing system comprises arc-shaped beam bottom plate templates, seat plate bottom templates, arc-shaped beam outside upper templates, arc-shaped beam outside lower templates and arc-shaped beam inside templates, wherein the arc-shaped beam outside lower templates are positioned below the arc-shaped beam outside upper templates; internal supports are arranged between the arc-shaped beam outside upper templates and the arc-shaped beam inside templates for supporting and enable the arc-shaped beam outside upper templates and the arc-shaped beam inside templates to keep set intervals; split bolts are used for connecting and fixing the arc-shaped beam outside upper templates and the arc-shaped beam inside templates; split bolts are used for connecting and fixing the arc-shaped beam outside lower templates and the arc-shaped beam inside templates; the arc-shaped beam bottom plate templates are respectively connected and fixed with the bottom ends of the arc-shaped beam outside lower templates and the arc-shaped beam inside templates; the seat plate bottom templates are respectively connected and fixed with the upper ends of the arc-shaped beam outside lower templates and the arc-shaped beam inside templates.

Description

technical field

[0001] The invention relates to a formwork structure and formwork supporting method of cast-in-situ concrete arc-shaped terraced stands. Background technique

[0002] With people's continuous demand for cultural and entertainment life, the construction of sports venues, performing arts venues, theaters, etc. will become more and more common, and the construction of stepped concrete arc stands is the main component of the above-mentioned buildings. For the stepped arc-shaped stands, the advantage is that the curves are smooth and beautiful, which can not only bring people the enjoyment of beauty, but also the plane layout of the stands is reasonable, which can save construction land to the greatest extent. However, the construction process of the arc-shaped stand is complicated, especially the formwork construction is labor-intensive and time-consuming. If the traditional method is used, it will not only have a long construction period, a large investment in t...

Embodiment Construction

[0043]In this embodiment, a cast-in-situ concrete arc-shaped grandstand is to be built, which is composed of radial inclined beams, circumferential arc-shaped beams, and arc-shaped seat boards. The horizontal projection of the overall stand looks like a fan-shaped concentric circle, and the vertical section looks like the steps of a staircase.

[0044] The specific structure is: both ends of the curved beam and the seat board are supported on the radial slanted beam, the radial slanted beam, the curved beam, and the curved seat board are poured as a whole, and the yin and yang of the intersection of the curved beam and the seat board The angles are right angles.

[0045] The radial inclined beam is the main frame beam, the section is generally about 500×1500mm, and the angle between it and the ground is generally about 30°;

[0046] The construction of arc-shaped beams (also known as circular ribbed beams) is the key technology to be solved in this embodiment. Its horizontal ...
