For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings to this utility model
Embodiment is described in further detail.
Detailed description of the invention
Builder's jack as shown in Figure 1, protects including support of encorbelmenting, scaffold and closing, and scaffold 6 rides upon encorbelments
On the overhanging type steel beam 1 supported, the end of encorbelmenting of overhanging type steel beam 1 uses drawknot steel wire rope 2 drawknot to fix, and sizing steel plate 3 is with fixed
Scaffold 6 is closed protection by shaped steel wire mesh sheet 4, and overhanging type steel beam 1 is shelved and is fixed on the pre-buried φ of agent structure layer 8 20 " U " type
On bolt 5, plug-in safe Dense mesh screen 7 after overhanging scaffold erection.
Overhanging type steel beam 1 is No. 18 I-steel, a length of 3.0m, fixing 1.8m, cantilever span 1.2m on the body construction.
End drawknot steel wire rope 2 model 6 × 19 of encorbelmenting of overhanging type steel beam 1, diameter 17 mm.Scaffold 6 uses the steel pipe of Ф 48 × 3.0
Design of coupler scaffold, is equipped with corresponding fastener and wall-connecting piece；Every layer of scaffold scaffold board uses φ 6 its boarding wire mesh sheet 6, wide
650mm, long 1800mm, steel wire grid spacing 50mm.
Sizing steel plate 3 uses " L " shape steel plate, is shelved on overhanging type steel beam 1, " L " shape steel plate width 1500mm, thickness
18mm, long 2000mm.
Its manufacture method is as follows:
1, " U " type bolt embedment
" U " type bolt is processed producer in specialty and is made, pre-buried to job site.Agent structure floor reinforcing bar binding completes
After, before concreting, the spacing according to overhanging type steel beam and the location dimension of " U " type bolt, calculate " U " type bolt and master
The distance of body structure axis, fixes bolt and is reliably connected with agent structure.
2, overhanging type steel beam is placed
Agent structure floor concreting completes, and starts to install overhanging type steel beam after reaching certain intensity.No. 18 works
Word manufactures overhanging type steel beam, installs the long 1.8m of fixing end, cantilever span 1.2m on the body construction.Overhanging type steel beam
Be placed in pre-buried " U " type bolt, put on 250mm × 100mm × 10mm(length × width x thickness) rectangle steel pressing plate fixed plate,
The cap nut of configuration dimension is fixed.
3, suspension scaffold bottom lock shoulder guard is installed
After overhanging type steel beam is laid, the bottom lock protection sizing steel plate 3 of builder's jack is installed, successively by " L " shaped steel
Plate is shelved on overhanging type steel beam, and " L " shape steel plate is reliably connected with overhanging type steel beam, and between steel plate, overlap joint is tight, with body junction
The position of structure contact meets the requirement of scaffold high-altitude Junk prevention.
4, scaffold building
At overhanging type steel beam position of sound production scaffold upright rod, set up order: put leger → by root establish bar and with greatly
Cross bar buckles → fills little cross bar and buckles → install first step leger and each vertical rod with vertical rod, leger and buckle → pacify first
Walk the interim hound of little cross bar → installation second step leger → little cross bar of installation second step → add, top and the big horizontal stroke of second step
Bar fastening (even wall pull bar is good and sound and drawknot point is removed the most afterwards) → install third and fourth step leger and little cross bar, the company of installation
Wall bar and drawknot point → connect vertical rod → add bridging → paving foot handsheet+tie up guard rail+skirt bar, hangs safety net protection → peace
Fill next step.
Take and carry out written telling somebody what one's real intentions are with constructing operation personnel before tearing scaffold open, work high above the ground check UP qualified after work on duty
Industry.Steel tube fastener passes through sampling observation retrial, qualified rear use.Use after onsite acceptance after having set up 6～8m scaffolds.Foot hands
Frame coordinative construction progress is set up, and a scaffolding height is less than more than adjacent wall-connecting piece two steps；If it exceeds adjacent wall-connecting piece with
Upper two steps, it is impossible to when arranging wall-connecting piece, should take support to draw fixation and building structure drawknot.
5, bridging is arranged
Rise along scaffold longitudinal direction two ends and corner, be barricaded as shears at the whole length of scaffold lateral surface and height brace
Support, is continuously disposed in outside scaffold in proper order.From outside scaffold two ends and corner, every 6 vertical rods set together, often
Road bridging width not less than 4 across, the inclination angle on brace and ground preferably between 45 degree and 60 degree, bridging is along the continuous cloth of frame height
Put.Bridging is crossed over vertical rod radical and is no more than 7.Bridging brace rotary buckle is fixed on intersecting therewith horizontal water
On the external part of flat bar or column.
6, protective equipment
Every layer of scaffold board uses its boarding wire mesh sheet 4 of φ 6 to lay, and scaffold alien invasion completely hangs safe Dense mesh screen 7, operation
On layer (work layer) bottom, 200mm height border arranges and sets up 1 road skirting board, completely spreads scaffold board.The above scaffold of overhang layer should be every
Setting horizontal protective (horizontal blanket net) every two-layer and height less than 10m, horizontal protective is to building edge.
7, security protection drawknot steel wire rope is installed
Scaffold has been set up with project progress, and the agent structure concrete strength of pre-buried suspension ring reaches more than 80%, carries out
The installation of security protection drawknot steel wire rope.Steel wire rope is pierced in the hanger of pre-buried suspension ring and overhanging type steel beam, by suspension ring one end
With no less than two Quincunx screw fastenings, with solid no less than two Quincunx screw fastenings after then other end steel wire rope first being strained
Fixed.
