Abstract

The invention provides a method for hauling steel wire ropes through an I-steel overhanging external scaffold and belongs to the technical field of architectural engineering. The method includes the steps that hanging rings are pre-buried corresponding to each row of internal and external vertical rods of the scaffold; two steel wire ropes are arranged on each hanging ring, wherein one steel wire rope hauls joint points of the external vertical rods and small cross rods, and the other steel wire rope hauls the joint points of the internal vertical rods and large cross rods; the small cross rods at the hauling joints need to abut against a wall; after the steel wire ropes are connected with the hanging rings and the two end inflections of the scaffold, the steel wire ropes are fixed through U-shaped steel wire rope clamps, clamp seats of the steel wire rope clamps are buckled on the work sections of the steel wire ropes, and bolts are buckled on the tail sections of the steel wire ropes; the steel wire ropes are tightened through chain hoists. The hauling structure of the steel wire ropes is more stable, and the hauling structure designed through the method and the position of the hauling structure have the advantages of being convenient to install and detach and more stable in scaffold structure, saving materials and labor and the like.

Description

A kind of i iron Overhanging Outside Scaffold hangs the method for drawing wire rope

Technical field

The present invention relates to construction engineering technical field, specifically a kind of i iron Overhanging Outside Scaffold hangs the method for drawing wire rope.

Background technology

I iron Overhanging Outside Scaffold technology was widely applied in nearly ten years, but it has following shortcoming, and i iron suspension scaffold every section is encorbelmented the highly the highest 20m that is about, and required i iron amount is many, and disposable infusion of financial resources is large, install with remove cumbersome.Adopt wire rope discharging type i iron fastener-style steel pipe scaffolding of encorbelmenting support body can be made to encorbelment highly increase to 40m, overcome the shortcoming that i iron suspension scaffold exists, but to there is erection insecure for current wire rope discharging type builder's jack, the defects such as stability is inadequate.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of safer, and more stable i iron Overhanging Outside Scaffold hangs the method for drawing wire rope.

The present invention takes following technical scheme:

I iron Overhanging Outside Scaffold hangs a method of drawing wire rope, and after being set up by i iron Overhanging Outside Scaffold, inside and outside the often row of corresponding scaffold, vertical rod arranges suspension ring; Described suspension ring are pre-plugged, and on the metope being anchored on building or crossbeam, suspension ring anchorage length is 30-40 times of wirerope diameter; Each suspension ring arrange two wire rope, and wherein one is hung and draws outer vertical rod and little cross bar interface point, and another hangs and draws interior vertical rod and leger interface point; The described little cross bar socketing some place that hangs need hold out against metope, scaffold introversion when avoiding tightening up wire rope; After described wire rope connects the two ends inflection of suspension ring and scaffold, all adopt U-shaped rope cramp to fix, the holder of rope cramp is buckled on the active section of wire rope, and bolt buckle is on the rear of wire rope; And with bottle gouard moved by hands, wire rope is tightened up.

Further, the described rope cramp for fixing every root wire rope is 6, and two ends respectively establish 3.

Further, the distance between described rope cramp is 6-7 times of wirerope diameter; The collar rope clamp the most nearby formed from wire rope inflection should near the collar.

The invention has the beneficial effects as follows: the present invention adopts the method for pre-buried steel loop, make wire rope hang pull-up structure more firmly, that is designed by this method hangs pull-up structure and position thereof simultaneously, has easy installation and removal, save material, manpower, the advantages such as scaffolding structure is more stable.

Detailed description of the invention

I iron Overhanging Outside Scaffold hangs a method of drawing wire rope, sets up plan according to scaffold, and at the pre-buried suspension ring of corresponding body of wall or crossbeam position, on the metope that suspension ring are fixed on building or crossbeam, suspension ring anchorage length is 35 times of wirerope diameters.In the present embodiment, scaffolding steel pipe adopts the steel pipe of diameter 48mm, wall thickness 3.5mm.After swinging scaffold is set up, treat that the concrete strength at pre-buried suspension ring place reaches 100% design strength and can install wire rope.When setting up scaffold, hang the little cross bar socketing some place hold out against metope by being positioned at.

Adopt two wire rope to hang scaffold to draw, more than suspension scaffold I-shaped steel layer, bottom shelf arranges off-load wire rope, and according to the antenna height of scaffold, sets up a collection of off-load wire rope every a height; 6 × 19 wire rope selected by wire rope.Article two, wire rope, wherein one is hung and draws outer vertical rod and little cross bar interface point, and another hangs and draws interior vertical rod and leger interface point; Wire rope two ends are passed suspension ring and are hung and socket a little, inflection, and fix with U-shaped rope cramp, often hold use 3 rope cramps; The holder of rope cramp is buckled on the active section of wire rope, and bolt buckle is on the rear of wire rope; And with bottle gouard moved by hands, wire rope is tightened up.Distance between rope cramp is 6-7 times of wirerope diameter.

The scaffold of the present embodiment set up the related request that quality meets " building operations fastener type steel pipe scaffold technical specification of security " (JGJ130-2012) and " construction safety check criteria " (JGJ59-2011).Another scaffold should make regular check on following items in using:

1) whether the setting of rod member meets detailing requiments with being connected;

2) whether Cantilever Beams loosens, and whether vertical rod is unsettled;

3) whether load transfinites;

4) whether tension member is solid and reliable;

5) whether wire rope is damaged; Whether i iron is out of shape; Whether fastening bolt loosens;

6) whether the deviation of vertical rod sedimentation and verticality meets code requirement;

7) whether safety prevention measure meets the requirements.

The present invention achieves good effect in actual applications.For Fangchenggang City First People's Hospital Comprehensive Inpatient project, if this project needs to install two-layer girder steel by traditional i iron suspension scaffold way, wire rope discharging type i iron suspension scaffold is adopted only to need to arrange one deck girder steel.Often take one deck rack-layer of encorbelmenting and need 150, i iron (4m), gross weight 14.5T, unit price calculates by 4000 yuan/T, need 58000 yuan.Two, every root i iron pre-buried diameter 20 round steel, the long 1.6m of every root, needs 1T reinforcing bar, needs stiffener mesh sheet to be about 1T in addition, reinforcing bar unit price 4000 yuan/T, then reinforcing bar expense is 8000 yuan.Install in addition, transport, the recruitment about 80 such as processing work day, labour cost 4000 yuan.In addition, remove i iron and about spend 2000 yuan of labour costs.Adopt i iron Overhanging Outside Scaffold of the present invention to hang the method for drawing wire rope, altogether drop into 7.4 ten thousand yuan less.

The present invention, also in Fangcheng District the People's Hospital Comprehensive Inpatient project, applied in the engineerings such as building, Nanning Architecture Design Institute, all obtained better effects.
