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

Embodiment 1

[0059] As shown in Figure 8, the original roof design was modified by experiment: it includes the overall layout of the following structural components: the eaves side beams are supported on the concrete columns at the eaves; the sloping roof panels of each section are from the eaves to the mid-span at an inclination angle of 30 degrees Elevated and tilted, its bottom is supported on the eave edge beams; the sloping roof panels of each section are connected to each other in the middle of the span to form a roof ridge; in order to better realize the large space, the resistance of the eave edge beams at the corners is fully utilized. Tensile force; in the middle is the partition wall of the house, so a tension beam is set up, which can be hidden in the wall; the rest is arranged at a certain distance from the horizontal push-resisting member, that is, the special-shaped concrete column, and the "L"-shaped vertical eaves side beam wall The limb section is 0.20 meters wide and 0.60...

Embodiment 2

[0061] As shown in Figure 9-11, the experimental modification-the original roof design: it includes the overall layout of the following structural components: the eaves side beams are supported on the concrete columns at the eaves; Elevated at 45 degrees and placed obliquely, its bottom is supported on the eave side beams; the sloping roof panels of each section are connected to each other in the middle of the span to form a roof ridge; in order to better realize the large space, the eave side beams at the corners are fully utilized There is no tensile beam in the middle, and only horizontal push-resistant components, namely concrete special-shaped columns, are arranged. The wall section of the "T"-shaped vertical eaves side beam is 0.20 meters wide and 0.60 meters long, and the wall protruding 0.20 meters thick is 0.40 meters. rice. This example includes dormer windows 10 and overhanging eaves 11, and the structure is relatively complicated, so the analysis and calculation ar...

Embodiment 3

[0063] As shown in Figure 12, the original roof design was tested and modified: it includes the overall layout of the following structural components: the eaves side beams are supported on the concrete columns at the eaves; the sloping roof panels of each section are at an angle of 26 degrees from the eaves to the mid-span Elevated and tilted, its bottom is supported on the eave edge beams; the sloping roof panels of each section are connected to each other in the middle of the span to form a roof ridge; in order to better realize the large space, the resistance of the eave edge beams at the corners is fully utilized. Tension force, without tension beams in the middle, arrange nine horizontal push-resisting members, that is, concrete special-shaped columns, "L" and "T" shaped vertical eaves side beams, the wall section is 0.20 meters wide, 0.70 meters long, protruding 0.20 meters thick Wall surface 0.50 meters, all the other items are with embodiment 2. Adopting this scheme sh...

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...
