A kind of bicircular arcs curved walls of the present embodiment go along with sb. to guard him the dividing method of node, including 1 side of segmentation of roofing fanning strip
Method and metope fanning strip dividing method；
Metope fanning strip dividing method, specifically: roofing sector is the disc of a quarter, designs the outermost long slab of fanning strip
Choose gutter about 200mm, radian is about 20 meters long herein, and it is 500mm that this fan-shaped 13 major part of long slab, which is arranged, microcephaly's 250mm equal part,
40 blocks of plates are divided into, by long slab major part one-to-two principle, this long slab is calculated and short slab major part in top overlaps range, circular arc is set
Type purlin does weld support and uses, and so on, because of device relationships, top can not topmost do shorter fanning strip, therefore be arranged
Top is sector cover plate, and the flat aluminium of underlay is connected with top fanning strip in rib of slab with pulling rivet.
Gutter lower part is metope, and relationship is arranged in wall board when because of construction, and 5 area's metope inner panel of rack is made on the outside of purlin,
Heat-preservation cotton is set between metope inner panel and Al-Mg-Mn plate, it is contemplated that heat-preservation cotton is not compressed, and high support, the metope in 6th area of steelframe are selected
Inner panel is arranged on the inside of purlin, and heat-preservation cotton is set in purlin gap, selects low support, actual node is as shown in Figure 8.
1 dividing method of roofing fanning strip, specifically: Al-Mg-Mn plate exterior wall is done with Al-Mg-Mn plate exterior wall at steelframe 6 at rack 5
Expansion joint processing, Al-Mg-Mn plate exterior wall shows there are certain height difference at two for this, adjusts Al-Mg-Mn plate plate by outermost aluminium sheet producer
Bracket length at rib guarantees that outside aluminium sheet surface of wall is consistent.Wall top is small at four angles of workshop, and broad in the middle, lower part becomes again
Small, a similar irregular sphere splits principle according to round sphere equalization, takes arc chord angle wall center maximum radian, press
400mm fanning strip major part equal part successively presses these dosis refractas at every purlin radian, calculates the size of fanning strip herein,
When row is single, fanning strip concentric reducer has been obtained, then show that every piece of fanning strip needs the radian of curved circle by section setting-out, in corresponding purlin
Place's overlap joint or welding (being more than or equal to 10 centimeters), finally complete the in-depth of wall sector Al-Mg-Mn plate at this.This in-depth node
And splitting scheme can be used as a Technical Reference of subsequent camber (ball-type) roofing, wall Al-Mg-Mn plate retaining design.
