Embodiment Construction

[0037] Such as Figure 12 As shown, the folded roof cast-in-place concrete construction method of the present invention, the main construction steps and technical control points are:

[0038] 1) Positioning elevation control:

[0039] (1) Roof girders and slabs are all slopes, the angle changes greatly, and there are many slopes in the formwork configuration, it is difficult to locate the oblique elevation of beams and slabs. Through detailed design and BIM technology, 3D modeling ( figure 2 , 3), in the 3D model, mark the elevation values ​​of all the beam and slab intersection points of the sloping roof, so as to solve the difficult problem of locating the oblique elevation of the beam and slab.

[0040](2) The erection height of inclined roof bent frames varies greatly, and it is difficult to control the elevation. According to the three-dimensional model drawings and marked elevations, conduct on-site review calculations, uniformly prepare a 1-meter elevation control l...

Abstract

The invention relates to a cast-in-situ concrete construction method of a folding-type roof. The cast-in-situ concrete construction method comprises the steps that (1) measuring and positioning elevation control are conducted, specifically, three-dimensional modeling is conducted through a BIM technology, and the elevation values of all beam and plate junction points of inclined roofing are markedin a three-dimensional model; (2) steel bars are machined, manufactured and constructed, specifically, all the inclined beam and plate steel bars are configured on a site in a real sample mode; and (3) inclined beam plate concrete pouring construction is conducted, specifically, columns, beams and inclined plates are sequentially poured, as for the pouring direction, distributing is overall conducted section by section from low to high, each section is poured from high to low, through the natural flow property of concrete, extending distributing is gradually conducted towards the low position, roofing beam plates with the large inclination are poured firstly, and extending is conducted gradually towards the roofing with the small inclination. Roofing construction comprises the steps of overall situation control, breaking up from a whole into parts, position plane control, and elevation vertical control, namely, a whole complex beam-plate structure is simplified into single spans or single components, then the single components are combined, the beam plane position is controlled through the control line of the floor, and the elevation of the junction points is controlled upwards from the unified elevation control point of the columns.

Description

technical field [0001] The invention relates to a folded roof, in particular to a construction method for cast-in-place concrete for a folded roof with a large slope. Background technique [0002] With the development of the construction industry and people's pursuit of the beautiful shape of buildings, architectural designers have become more and more perfect in the shape of buildings, and various shapes of buildings have emerged, especially the overall shape and facade shape of public buildings. And the roof shape is more colorful. In the early stage of the development of the construction industry, most of the shapes were realized through steel structures, wood structures, etc. With the further development of the construction industry, various shapes of various materials have also been favored by architects. reinforced concrete shape. Different shapes have different construction requirements for reinforced concrete. The more common ones are a small number of slanted col...
