Designing method of reinforced concrete large space slope roof

Abstract

This invention discloses a design method of large space reinforced concrete sloping roof. It includes the following structural component of the overall layout settings : eaves edge beam of the office roof was supported on concrete wall, column or masonry walls; slopes of the roof slab from the roof to mid-span were placed with increasing tilt angle, its bottom was supported on edge above beam; the slope of the roof slab is cross-linked to each other to constitutes the roof; except roof edge beam, there are no concrete walls in internal plane and columns to form the space bellowing the elevation; the roof beams along the edge beam spacing sets up resistance against pushing thrust component. As a result of these technology programs, compared with the existing technology investment, it not only saves about 10% investment and shorten about 30% project time of the building the roof , bring professional benefit to structure, but also can give the building professional design to expand a new leeway ,let the users free to use the space,make the available space increased about 35% to a standard level.

Description

technical field [0001] The invention relates to a design method of a civil engineering building structure, in particular to a design method of a reinforced concrete large-space sloping roof. Background technique [0002] In recent years, reinforced concrete sloping roofs have been widely used, but there is no uniform method and technical standard. The most common design problem at present is unreasonable structural layout, which not only leads to complicated and wasteful components, but also seriously affects the use of the roof by users. In terms of structural layout, designers often raise all the walls and columns inside the plane to the roof according to the layout of standard floors; The contour lines of flat roof ridges and inclined roof ridges are regarded as frame members (beams, inclined beams or inclined columns), and the calculation model is established blindly according to the frame. In fact, for general houses, the stress state of double-slope and multi-slope r...

Problems solved by technology

But what they reveal is only the law of vertical load effect when the base is rigid and there is neither horizontal expansion nor vertical settlement displacement around the surroundings, although the calculated stress near the ridge reflects the arch, The characteristics of the shell, but assuming such boundary conditions are far from the actual situation of general engineering, which conceals the fundamental characteristics of the longitudinal mid-span settlement and outward expansion of the eaves, and the bottom edge requires a large amount of reinforcement to bear the tensile force, which hides a huge hidden danger. Therefore, it cannot be used for general engineering design
