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

Embodiment 1

[0027] In this embodiment, the lean construction method of fan-shaped modeling function level should be figure 2 On the shell-shaped roof structure layer J shown, the waterproof layer F, the lightweight concrete insulation layer H and the surface decorative layer M are constructed in layers. The specific construction process is as follows:

[0028] 1. Make the waterproof layer first. After cleaning the base layer and local polishing, apply a single-component polyurethane waterproof coating film. The final film thickness is not less than 3mm. Due to the ups and downs of the roof, in order to prevent the uneven thickness of the coating film due to the free flow of the highly fluid polyurethane, the coating film construction should refer to image 3 From bottom to top, and from low to high in each groove.

[0029] Then use the architectural CAD to lay out the control network, such as Figure 4 As shown, in the general plan of the shell-shaped roof, the roof control grid is est...

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). ...
