Refer to Fig. 1-3, in the utility model embodiment, a kind of one-sided support shuttering inner corner trim bracing or strutting arrangement, comprise that sizing corner steel backing is stupefied 1, steel backing is stupefied 2, to support arrangement 3, girt 4 and vertical strut 5, the steel backing stupefied 2 that described sizing corner steel backing stupefied 1 is supported with tripod by core ribbon, steel pin 21 links into an integrated entity; Described sizing corner steel backing is stupefied 1, the bottom of steel backing stupefied 2 is fixed by pad and nut and stone bolt, and this embedding anchor bolts is in the concrete floor of having built; Described to support arrangement 3 comprise connection end 301, adjustable screw 302 and to support steel pipe 303, described connection end 301 rear end is connected with steel backing stupefied 2 by steel pin 21, the front end of connection end 301 is welded with adjustable screw 302, this adjustable screw 302 is provided with the oil holder 304 for regulating, and one end end near oil holder 304 of adjustable screw 302 is connected with to supportting steel pipe 303; Described with steel backing stupefied 2, also pretension is connected by adjustable screw 302, connection end 301 to support steel pipe 303; Described sizing corner steel backing is stupefied 1, connect for overall between support arrangement 3 by girt 4, vertical strut 5; The corner of described sizing corner steel backing stupefied 1 is determined (90 ° are in the majority) according to entity structure corner, sizing processing, and inside sizing corner steel backing stupefied 1 reinforcement of weld rib; Described girt 4, vertical strut 5 are lease pipe fitting, are linked as entirety by fastener by single to support arrangement 3.
One-sided body of wall bight additional support calculated description
One, basis
1, concrete structure engineering construction and standards of acceptance (GB50204-2002)
2, Code for design of steel structures (GBJ17-2005)
3, building structure Static Calculation handbook
4, construction work big template technology code (JGJ74-2003)
5, all-steel big shuttering application technology code (DBJ01-89-2004)
Two, designing and calculating index adopted value
1, steel physical performance index elastic modulus E=206000N/mm2
Mass density ρ=7850kg/m3
2, steel strength design load tension, resistance to compression, bending resistance f=215N/mm2
Shearing resistance fv=125N/mm2
3, steel pipe adopts Ф 48*3.0I=10.783 (cm4), W=8.985 (cm3), i=1.594 (cm), A=4.241 (cm2)
Three, lateral pressure
If cylinder builds height 5.0m.Body of wall lateral pressure F1=Min (0.22 γ c*t0* β 1* β 2*V^1/2, γ cH)=0.22*24*200/ (20+15) * 1.0*1.15*2^1/2)=49.07KN/m2
F2＝24*5＝144.00KN/m2
Get F=60.00KN/m2
Topple over load (conduit feed): P=6.00KN/m2
Effective head height h=F/ γ c=2.500m
Four, corner buttresses calculates:
Support during construction and adopt Ф 48*3.0 steel pipe, adopted by horizontal for both sides, bight keel U holder to support, lateral pressure reliable delivery when ensureing to build.Maximum support distance is 3.8 meters, and middle vertical additional 1 Ф 48 vertical rod, horizontal direction increases Ф 48 rod member.The calculated length of Ф 48*3.0 steel pipe support is reduced to 3.8/2=1.9 rice.
One side formwork back cord maximum spacing is 0.8 meter, and steel pipe support level interval is 0.4 meter, then single Ф 48*3.0 steel pipe support force design value: 60 (N/m2) * 0.8 (m) * 0.4 (m) * 1.2=23.04 (KN)
Support and adopt Ф 48*3.0 steel pipe stability calculation:
λ=L/i=1900/15.94=119.2<150, rigidity meets the demands!
Look into coefficient of stability table and obtain coefficient of stability ψ=0.44
Stable stress σ=N/ ψ/A=23.04*1000/0.44/424.1=123.47 (N/mm2) <215 (N/mm2)
Condition meets.Therefore Ф 48*3.0 steel pipe is selected can to meet rigidity and force request as single side bracing bight additional support.
