Embodiment Construction

[0027] In the following, the implementation of this construction method will be described by taking an antique building with a hyperbolic sloping roof as an example.

[0028] A construction method for a reinforced concrete hyperbolic slope roof formwork system, the formwork system includes a formwork system and a support system; the formwork system includes a main keel, a secondary keel and a formwork; Upright poles, horizontal bars and vertical scissor braces are set between the supporting poles, and horizontal scissor braces are set between the horizontal bars; In the U-shaped roof support system of the support system, the secondary keel is arranged perpendicular to the direction of the main keel along the direction of the roof slope. The secondary keel must have a certain degree of flexibility and can be bent into a curve effect. In order to ensure the stability and reliability of the support system, wedges should be used to fill the gaps in the oblique triangles.

Abstract

The invention discloses a construction method of a reinforced concrete hyperbolic slope roof formwork system. The formwork system includes a formwork system and a support system, wherein the formworksystem includes a main keel, a secondary keel and formworks, the support system adopts a bowl-buckle support frame, and a U-shaped top support is arranged on the top of a support pole. The construction method comprises steps that a BIM model is established, formwork matching is performed through model design software, the support pole is mounted, the 1m control line in parallel with a curved roofis suspended, the main keel is laid, and formwork blocks are laid. The method is advantaged in that accurate control of the curvature of the surface during construction can be guaranteed, and the forming effect of the reinforced concrete hyperbolic slope roof is realized.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a reinforced concrete hyperbolic slope roof formwork system. Background technique [0002] For Chinese-style antique buildings, double-curved sloping roofs are one of the common forms. The double-curved sloping roofs are sloped on all sides, and the main ridges and oblique ridges of the roof are warped. During the cast-in-place process of reinforced concrete double-curved roof, there are many difficulties in the construction of the formwork system, such as: (1) how to accurately understand and turn over the curvature of the warping angle; (2) how to accurately and conveniently realize the measurement and control of the roof curvature; ( 3) How to accurately complete template matching and reasonably separate templates. For the above-mentioned difficulties, there is no effective solution in the prior art, and usually only approximate treatment is poss...
