Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 is the portable high-altitude operation platform of constructing for girder steel 10 shown in the utility model embodiment, and it comprises framework 1, the support bar 2 be arranged on framework 1, the rope 3 being arranged on framework 1 both sides and first, second fixture 4,5 adjustable.One end of first fixture 4 is arranged on framework 1, and it comprises first clamping section 41 with the first jaws (not shown) and the first puller bolt 42, first jaws be located in the first jaws is dismountable clamping in girder steel 10 bottom flange.Second fixture 5 comprises second clamping section 51 with the second jaws (not shown) and the second puller bolt 52, second jaws be located in the second jaws is dismountable clamping in girder steel 10 top flange.The restrict two ends of 3 ropes are separately fixed on the second clamping section 51 and framework 1.
Concrete, the first clamping section 41 is fixed on the both sides of framework 1.Second clamping section 51 is also provided with hook 53, and rope 3 hanging sleeve is in hook 53.This portable high-altitude operation platform also comprises multiple for regulating the wire clips 6 of rope 3 connecting length, and wire clips 6 is fixed on rope 3.In the present embodiment, framework 1 is flute profile, and it is by three L50 × 5 angle splice joints around forming, and this angle steel material is Q235B.First, second clamping section 41,51 is made by steel plate, and this steel plate material is Q235B, and thickness is 15mm, and first, second puller bolt 42,52 is M22 bolt.Rope 3 is made up of steel wire, and this steel wire diameter Φ is 16mm, and length is 1200mm.Preferably, the first clamping section 41 and hook 53 are all separately fixed on framework 1 and the second clamping section 51 by the mode of fillet weld.
This portable working platform designs according to the operating space of an operating personnel, load consideration is born 100kg and is checked framework 1 stability, the bearing capacity of main checking computations framework 1, the bearing capacity of first, second fixture 4,5, the second clamping section 51 and hook 53 weld seam bearing capacities and the first clamping section 41 and framework 1 weld seam bearing capacity.
Consider dead load in calculating, Load Combination is 1.2DL+1.4LL, and wherein DL is dead load, and LL, for acting on the outer middle side part joint load of framework 1, is taken as 1000N.Set up computation model by MidasGen analysis software, framework 1 adopts beam element, and framework 1 adopts cable elements with the rope 3 of girder steel 10 top flange.
The checking computation results analysis of a, framework 1
Known by MidasGen analysis software, under 1000N Concentrated load, framework 1 maximum displacement 0.8mm, maximum stress 159.7MPa < f=215MPa, wherein f is Q235 steel strengths in tension and compression design load.Framework 1 meets requirement for bearing capacity.
The Analysis of Bearing Capacity of b, first, second fixture 4,5
First, second fixture 4,5 holding out against by M22 bolt, makes side and girder steel 10 edge of a wing close contact in the non-bolt hole of first, second clamping section 41,51, resists horizontal direction load.For 4.8 grades of M22 bolts, table look-up and know that its breakdown torque value is 225Nm, get that its prefastening torque is breakdown torque 70%, that is:
M
t＝M×0.7＝225MPa×0.7＝157.5MPa
Wherein, Mt is prefastening torque, and M is breakdown torque.
By formula M
t=K × P
0× d/1000 can release, P
0=1000M
t/ (K × d), wherein P0 is pretightning force, and K is screwing force coefficient, and d is screw thread nominal diameter.Table look-up and know, K=0.18, d=22mm, substitute into pretightning force formula, pretightning force P0=39.8KN when can obtain every bolt tightening.
According to force balance principle, the pressure of the other side of first, second clamping section 41,51 and tools for bolts ' pretension dynamic balance.Therefore, pressure N1=P0=39.8KN between the second fixture 5 and girder steel 10 top flange, pressure N2=2P0=79.6KN between the first fixture 4 and girder steel 10 bottom flange.
For Q235 steel, spray zinc-rich coating after its shot peening, between steel, friction factor is that friction bearing capacity F1, F2 of the 0.35, second, first fixture 5,4 is respectively:
F
1＝N
1×μ＝39.8KN×0.35＝13.93KN
F
2＝N
2×μ＝79.6KN×0.35＝27.86KN
Calculated by MidasGen analysis software and know, on girder steel 10, bottom flange knee level counter-force is 726N, much smaller than the friction bearing capacity of first, second fixture 4,5, meets requirement for bearing capacity.
C, the second clamping section 51 and the fillet weld Analysis of Bearing Capacity linking up with 53
Hook 53 adopts Ф 10 reinforcing bar, is connected by fillet weld with the second clamping section 51.According to " Code for design of steel structures " (GB50017-2003) 7.1.3 related content regulation, active force is parallel to the orthogonal fillet weld in fusion length direction, its strength checking performs as follows:
Meet requirement for bearing capacity.
The weld seam Analysis of Bearing Capacity of d, the first clamping section 41 and framework 1
First clamping section 41 is connected by fillet weld with framework 1, specify according to " Code for design of steel structures " (GB50017-2003) 7.1.3 related content, active force is parallel to the orthogonal fillet weld in fusion length direction, its strength checking performs as follows:
Meet requirement for bearing capacity.
