Abstract
The invention discloses a T-beam hoisting method, which comprises the following steps of: A, inserting stress members into the bottom of a T-beam; B, vertically inserting steel slings into preformed holes of upper wings of the T-beam, wherein the bottom of each steel sling is provided with a strip-shaped hole of which the upper part has a larger radius and the lower part has a smaller radius; C, sleeving the steel slings on two sides of the T-beam on steel pins through the strip-shaped holes, and connecting the tops of the steel slings with lifting hooks; D, making semi-circles on the lower parts of the steel slings clamped on the steel pins after the T-beam is lifted; and E, hoisting in place, loosening the lifting hooks, making the steel slings move downwards, and retreating the steel slings under the action of restoring force of pressure springs when semi-circles on the upper parts of the strip-shaped holes correspond to knobs. When the steel slings are used, the steel slings pass through the preformed holes of upper wings of the T-beam, the bottoms of the steel slings are sleeved on the steel pins through the strip-shaped holes, and after the T-beam is lifted, the semi-circles on the lower parts of the steel slings are clamped on the steel pins; and after the T-beam is hoisted in place, the steel slings automatically retreat under the action of the restoring force of the pressure springs. The steel slings are convenient to mount, the labor intensity is low, time is saved, cost is low and the service life is longer.
Description
Technical field
The present invention relates to a kind of hanging method, relate in particular to a kind of hanging method of T type beam.
Background technology
The people who is engaged in road and bridge construction for a long time knows, the hanging method of existing prefabricated T type beam is: the preformed hole that at first suspension ring of steel rope lace is passed T type beam upper limb, walk around from the bottom of prefabricated T type beam then, preformed hole from prefabricated T type beam upper limb opposite side passes again, suspension ring with the steel rope two ends hang on the suspension hook of loop wheel machine at last, just can begin lifting.Adopt above-mentioned steel rope to carry out hoisting prefabricated T type beam and mainly have following deficiency: one, the suspension ring of steel rope lace are when passing preformed hole, because of the diameter of steel rope is bigger, suspension ring penetrate the comparison difficulty, and are both time-consuming, require great effort very much again, increased work-hours and labour intensity; Two, adopt large diameter steel rope lifting, steel rope not only lace suspension ring is difficult, and the cost height; Three, adopt the steel rope lifting, the steel rope operating cycles is not long, often needs to change.
Summary of the invention
At the prior art above shortcomings, it is long to the invention provides a kind of operating cycles, easily passes T type beam upper limb preformed hole, and saves man-hour, the hanging method of the T type beam of the economy type of reduction labour intensity.
The hanging method of T type beam provided by the invention comprises the steps:
