Construction supporting formwork and construction process for hyperboloid wood grain fair-faced concrete roof

Abstract

The invention relates to the field of building construction, and provides a construction supporting formwork and a construction process for a hyperboloid wood grain fair-faced concrete roof. A steel structure supporting system is used for replacing a common socket-type disc buckle type scaffold supporting system, and the supporting safety is ensured. The curvature of a main keel at the top of the supporting system is set according to 50cm of a grid elevation map, and a preliminary curved surface effect is achieved; a wood secondary keel which is cut in a numerical control mode is installed on the main keel, due to the fact that the machining precision is high, the curvature of the wood secondary keel can be consistent with that of a drawing, and the designed hyperboloid roof is well fitted. Meanwhile, the secondary keel can be conveniently and reliably connected with a formwork and a wood grain plate at the top, and the forming effect of wood grain fair-faced concrete is ensured. According to the construction process, common roof construction processes are designed separately, results are gradually formed and integrated, the process is complex and simple, the construction difficulty is reduced, and the forming quality of the roof meets the design requirement after the roof is completed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a hyperboloid wood-grain fair-faced concrete roof construction support formwork and a construction process. Background technique [0002] Domestic architectural design breaks the confinement of traditional models and pursues diversified modeling structures. Especially for landmark buildings and large-scale exhibition projects, in order to pursue good visual effects, special-shaped roof structures are often designed. Hyperbolic wood-grain fair-faced concrete roof is one of them. The roof span is large, the load is large, and the height is large, so the construction technology is difficult. The roof section has no fixed curvature, and the negative bending moment formed by the hyperboloid can easily cause the supporting system below to overturn. The ordinary socket-type ring-type scaffolding support system cannot meet the construction requirements. Contents of the invention ...
