Device for mounting steel beam on floor slab and construction method of device

Abstract

The invention relates to a device for mounting a steel beam on a floor slab and a construction method of the device. The device comprises a bracket, supports, lifting devices and lifting ropes, wherein an accommodating groove with an upward opening and matched with the steel beam is formed in the bracket; the steel beam is arranged in the accommodating groove, and the top of the steel beam protrudes out of the bracket; the supports are vertically arranged on the floor slab and correspond to a to-be-mounted position of the steel beam; the lifting device are fixed on the supports separately; oneend of each lifting rope is fixed to one support, each lifting rope vertically penetrates through the floor slab downwards, bypasses the bottom of the bracket and then penetrates through the floor slab upwards, and the other end of each lifting rope is fixed to one lifting device; and the lifting ropes are retracted through the corresponding lifting devices, and support the corresponding supportsto move upwards to the top of the steel beam to be attached to the bottom surface of the floor slab. A lifting lug does not need to be arranged on the steel beam, so that the problem that the upper surface of the steel beam cannot be in close contact with the bottom of a concrete floor slab due to the presence of a steel wire rope or the lifting lug on the upper surface of the steel beam in the prior art can be solved. Mounting and construction are convenient and labor-saving, and the device can be recycled.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a device for installing a steel beam on a floor slab and a construction method thereof. Background technique [0002] When installing steel beams inside a poured concrete floor, it is necessary to bring the upper surface of the steel beams into contact with the concrete floor. In the prior art, steel wire ropes or lifting lugs are provided on the upper surface of the steel beam, and the hoisting device is used to directly hook the steel wire rope or lifting lugs to the preset installation position to complete the installation. However, due to the existence of steel wire ropes or lifting lugs on the upper surface of the steel beam, the upper surface of the steel beam cannot be in close contact with the bottom of the concrete floor, and the structural force does not meet the design requirements. Contents of the invention [0003] The purpose of the present invention is to ov...
