Embodiment Construction

[0029] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0030] A kind of construction method of cast-in-place concrete curved inclined cylinder structure described in this embodiment, such as figure 1 ,Specific steps are as follows:

[0031] Step 1, measuring and setting out:

[0032] In the underground stage, according to the control points of the building outside the foundation, the control line is projected by the direction method or the straight line method of the front and back mirrors, and the distance between the adjacent axis and the adjacent axis is correct before use.

[0033] Since the starting line of the plane position of the inclined wall column is closely related to the elevation, before the floor is laid out, the floor elevation of the position to be set out is generally measured with a level, and the highest value is taken as the elevation of the plane position li...

Abstract

The invention provides a construction method of a cast-in-place concrete curve surface inclined tube body structure. The construction method is applicable to the construction of a cast-in-place reinforced concrete structure with great horizontal cross section curve surface dimension and with a vertical shaft inclined for a certain angle in industrial and civil buildings. The advantages that a multilayer plate can be easily processed and spliced, the building of a steel pipe scaffold is convenient, and the like are used; a polyhedron fitting curved surface body is spliced by formworks; by controlling the polyline width of a polyhedron horizontal cross section pattern, the chord height is about 2mm; the goal of smooth facade curve surface is achieved; the bare concrete requirement is met; for the formwork support, an inner rigid frame bent is built by a scaffold; and the formworks are supported and pulled from the inside in a single direction, so that the support problem of the tube bodyinclination is solved.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method for a cast-in-place concrete curved surface inclined cylinder structure, which is suitable for cast-in-place reinforced concrete structures with large horizontal section curved surfaces and vertical axes inclined at a certain angle in industrial and civil buildings construction. Background technique [0002] With the continuous development of my country's construction industry, modern architectural styles are becoming more and more diverse. Architectural design has broken through the shackles of the past, and a number of buildings with novel shapes and unique images have emerged, reflecting the strong atmosphere of the times and artistic taste. Among them, there are many buildings that use curved surface modeling as the means of architectural expression, and some even break the traditional method of vertical modeling, allowing the curved surface to incline a...
