Oval beam plane construction paying-off method

Abstract

The invention relates to the technical field of engineering construction, in particular to an oval beam plane construction paying-off method. Comprising the steps of drawing deepening, surveying and setting-out, monitoring acceptance, technical disclosure, structure construction and the like. According to the design, the CAD technology is adopted for deepening the drawing, the deepened drawing is arranged in the coordinate general drawing in a sleeving mode, then surveying and setting-out operation and final structure construction are conducted at the designated position according to the deepened drawing, the setting-out construction efficiency is improved, the operation precision is improved, and the setting-out error is reduced; the overall method is scientific and reasonable, convenient to operate, accurate in positioning and checking and capable of being widely applied to various constructional engineering needing to build the oval hollow beam, the paying-off construction efficiency of oval beam plane construction can be improved, adjacent floor planes outside the hollow portion of the oval beam are collinear, and therefore the construction quality of the oval beam is improved.

technical field [0001] The invention relates to the technical field of engineering construction, in particular to an elliptical beam plane construction laying-out method. Background technique [0002] With the development of society and the needs of people's work and life for building structures, buildings with special-shaped components are commonly encountered in the construction process, especially for the accurate positioning of the upper and lower floors of hollow elliptical beams. The conventional construction lofting is adopted on the ground floor. Determine the ellipse focal point line drawing circle method, and the hollow elliptical beams on the upper floors are set out by hanging vertical lines.

[0002] With the development of society and the needs of people's work and life for building structures, buildings with special-shaped components are commonly encountered in the construction process, especially for the accurate positioning of the upper and lower floors of hollow elliptical beams. The conventional construction lofting is adopted on the ground floor. Determine the ellipse focal point line drawing circle method, and the hollow elliptical beams on the upper floors are set out by hanging vertical lines. Due to the unevenness of the first floor, the elastic deformation of the set line, and the back and forth swing error of the plumb weight, it is difficult to fix the The side of the elliptical beam is controlled on one elevation, which brings certain difficulties to the construction lofting

However, at present, there is no construction lofting scheme for elliptical beams that can effectively solve the above problems. In view of this, we propose a planar construction setting out method for elliptical beams
