Roof modeling function layer lean construction method

Abstract

The invention relates to a roof modeling function layer lean construction method, and belongs to the technical field of constructional engineering. The method includes the steps: arranging a control network; constructing control points; distributing mortar cones; isolating grid areas; finishing roundness; constructing functional layers; treating expansion joints. The method properly solves the problem that all points of a seashell roof structure layer forming surface and a finished surface of a final building need to be consistent in normal thickness. The method is practicable, and construction efficiency is improved on the premise of ensuring quality.

Description

technical field [0001] The invention relates to a construction method of roof modeling function levels, in particular to a lean construction method of shell-like roof modeling function levels, which belongs to the technical field of construction engineering. Background technique [0002] The undulating shells of deep-sea shellfish are not only beautiful in appearance, but also extremely compressive. The Chinese patent application with the application number 201410617286.8 uses the principle of bionics to disclose "a fan-shaped imitation shell roof and its construction method", which solves the problem of composition and construction of each node of the fan-shaped imitation shell roof. [0003] However, in construction, it is difficult to ensure that the thickness of each functional layer of the architecturally designed curved roof is uniform (that is, the normal thickness of each point perpendicular to the tangent direction of the structural forming surface is consistent). ...

AI Technical Summary

Problems solved by technology

However, curved surface buildings such as shell-like roofs are not so simple. If only the shape of the forming surface F1 of the structural layer is copied and then vertically translated by 300mm as the building completion surface F2, it will be as follows: figure 1 As shown, the thickness of the surface from the base layer is usually only 210mm, which does not meet the design requirements

Practice also shows that the waterproof layer F, the lightweight concrete insulation layer H and the surface decorative layer M are layered on the shell-shaped roof structure layer J (see figure 2 ) because there is no mature construction method that can be used for reference, and the curved surface of the structural layer relies on manual smoothing, and there are large errors, which makes it impossible to accurately determine the normal direction of each point in the construction of the curved surface building layer. Therefore, if the construction process problem is not properly solved , it will not be possible to ensure that the normal thickness of each point from the forming surface of the roof structure layer to the final building completion surface is consistent, which will affect the construction quality
