Abstract

The utility model discloses a cantilevered external frame lifting wire rope embedded system, which belongs to the technique field of building operations. The embedded system comprises a wire rope, a rim girder, a burning wire and a steel I-beam, the part of the wire rope extending out of the rim girder is square-crossed and fixed with a main bar at the upper part of the rim girder obliquely by adopting the burning wire, and the inclined drawing part of the wire rope and the wire rope at the part of the steel I-beam are on the same plane. The utility model provides the novel external frame lifting wire rope embedded system, solving the problems that the investment in steel pipes and jigs is high, the embedding part is abnormal in construction, and the hidden trouble of water seepage exists.

Description

The outrigger of encorbelmenting lifts the wire rope embedded system

Technical field

The utility model belongs to technical field of building construction, is specifically related to a kind of outrigger of encorbelmenting and lifts the wire rope embedded system.

Background technology

Often apply to encorbelment outrigger and integral lifting rack in the high-building construction, know by contrasting us, the integral lifting rack expense is higher to be applicable to that more than the building height 60m, the building that the single building area is less, elevation of building is the plane is more.At present general high-building construction is commonly used is the outrigger of encorbelmenting.

Encorbelment outrigger in construction, and the method that lifts conventional application of wire rope is before next floor concreting, pre-buried short steel pipes (about 50mm), and spacing is generally selected 1500mm.After steel pipe is buried underground, adopt wire rope one end to be buckled on the steel pipe, an end is buckled on the steel I-beam of encorbelmenting, and realizes the unloading to the outrigger of encorbelmenting.Construction has following shortcoming like this, and the steel pipe waste is big, and wire rope anchor clamps input is many; Its two, carrying out masonry when construction, pre-buried position can not normal construction, construction is to stay to establish the steel pipe position and build with pea gravel concreten at last usually, complex procedures is time-consuming; Its three, reserve the masonry construction of steel pipe position and finish the back and have the hidden danger that seeps water.

The utility model content

In order to overcome the deficiency of existing technology, the utility model has overcome above-mentioned three shortcomings, proposes new outrigger and lifts the pre-buried technology of wire rope, has eliminated that steel pipe and anchor clamps have high input, pre-buried position can not normal construction, have the problem of infiltration hidden danger.

The utility model comprises: wire rope, frame beam, burn silk and steel I-beam, described wire rope stretches out frame Liang Chu and frame beam top master's muscle to be adopted and burns a diagonal cross and be cross and fix.

The oblique pull portion of described wire rope and steel I-beam place wire rope are at grade.

Realize that concrete steps of the present utility model are:

1) the outrigger rope capacity of encorbelmenting is calculated, is undertaken by following formula:

Outrigger rope capacity=L1+L2+L3 encorbelments

--wire rope inclined segment length

L2=h+10d--pre-buried rope capacity in the frame beam

-wire rope is walked around i iron to free end length

The H--story height

The L--i iron length of encorbelmenting

H-frame beam deck-molding

The d-wirerope diameter

2), pre-buried rope capacity h+10d in the frame beam, steel cord ends is removed oil in the pre-buried length range.

3), carry out blanking, according to calculated length L then wire rope is carried out pre-buried fixing.Wire rope stretches out frame Liang Chu and frame beam top master's muscle to be adopted 22# to burn a silk diagonal cross to be cross and to fix, make the assurance of oblique rollering steel silk rope and steel I-beam place wire rope at grade.

4), step into the pre-buried short steel pipes of row and be connected with external scaffolding by " building operations fastener type steel pipe scaffold technical specification of security " wall-connecting piece requirement two step three.

5), build the floor concrete, treat concreting after intensity reach 15MPa, the installation of promptly carrying out steel I-beam lifts.

6), the PVC sleeve pipe is passed wire rope, be fixed on wire rope and frame beam handing-over position, prevent steel rope abrasion.

7), after the steel I-beam installation, adopt the wire rope clamp specially and anchor clamps are fastening unloads.

The utlity model has following beneficial effect: the outrigger of encorbelmenting that the utility model provides lifts the wire rope embedded system, propose new outrigger and lift the pre-buried technology of wire rope, eliminated that steel pipe and anchor clamps have high input, pre-buried position can not normal construction, have the problem of infiltration hidden danger.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.Fig. 1-1 is the utility model overall schematic; Fig. 1-2 lifts the i iron schematic diagram for the utility model; 6 are depicted as the wire rope jig among Fig. 1-2.The utility model comprises: wire rope 1, frame beam 2, burn silk 3 and steel I-beam 4, described wire rope 1 stretches out frame Liang2Chu and frame beam top master's muscle to be adopted and burns 3 diagonal cross and be cross and fix, as Figure 1-3.Fig. 1-4 is the pre-buried wire rope contact of a utility model schematic diagram, and 7 are depicted as the PVC sleeve pipe among the figure.

Its concrete steps of the present utility model are:

1), determines wire rope specification and wire rope spacing.

2), before pre-buried i iron floor concreting, according to the pre-buried snap ring of vertical pole ' s span, during concreting, prevent to collide snap ring and produce displacement.

3) compressive strength reached 15MPa, the installation steel I-beam after, concreting was finished.

4), when carrying out next floor reinforcing bar binding,, in the frame beam, install, according to the single rope capacity of calculating that lifts wire rope is extended walk around at the bottom of the frame beam at the bottom of the frame beam fixing behind master's muscle with pricking silk.

5), treat concreting after intensity reach 15MPa, pass wire rope with the PVC sleeve pipe, the PVC casing clamp at frame beam and wire rope handing-over position, is prevented that wire rope from contacting the wire rope that weares and teares with concrete.Walk around the steel I-beam of encorbelmenting with the free end wire rope again, adopt the wire rope clamp specially and anchor clamps are fastening unloads.
