Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a hoop node of a conversion layer under an I-shaped steel beam. Background Art

[0002] At present, after some building constructions are completed, additional construction will be carried out according to later requirements to meet user needs. For example, the first floor of a restaurant is suitable for adding a mezzanine. The mezzanine is an additional construction later and can be supported by I-shaped steel beams, and a lightweight floor is used as the floor. Therefore, it is impossible to install a hoop on the I-shaped steel beam as a whole, nor can a hanging rod be fixed on the lightweight floor. Welding the hanging rod directly on the I-shaped steel beam will damage the fireproof layer of the I-shaped steel beam. For this reason, a hoop node of a conversion layer under an I-shaped steel beam is proposed. Summary of the Utility Model

[0003] This application provides a hoop node of a conversion layer under an I-shaped steel beam to solve the problems of easy damage to the fireproof layer of the steel beam and slow installation speed during the installation of the conversion layer.

[0004] To solve the above technical problems, this application provides a hoop node of a conversion layer under an I-shaped steel beam, including: a plurality of lightweight floors, an I-shaped steel beam arranged between adjacent lightweight floors, and L-shaped supporting members arranged on both sides of the top flange of the I-shaped steel beam; an installation cross beam is lapped on the upper surface of the bottom flange of the I-shaped steel beam, and a fixing mechanism is arranged between the installation cross beam and the I-shaped steel beam. The fixing mechanism includes an angle code welded to one side of the installation cross beam and a C-shaped clamping member arranged on the angle code. The angle code and the bottom flange of the I-shaped steel beam extend into the opening of the C-shaped clamping member. A fixing bolt is vertically arranged on the C-shaped clamping member, and the fixing bolt abuts against the top of the angle code.

[0005] In some embodiments of this application, the installation cross beam and the fixing mechanism are symmetrically arranged along the web of the I-shaped steel beam. A plurality of installation holes are spaced apart in the length direction of the installation cross beam, and a hoisting mechanism is arranged in the installation holes.

[0006] In some embodiments of this application, the hoisting mechanism includes a through wire hanging rod extending into the installation hole, a gasket and a fixing nut installed on the top of the through wire hanging rod, and a ceiling light steel keel arranged at the bottom of the through wire hanging rod. A ceiling is installed on the ceiling light steel keel.

[0007] In some embodiments of this application, the opening of the C-shaped clamping member is 35 mm, and the material of the C-shaped clamping member is cast iron.

[0008] In some embodiments of this application, the angle code is a 5*5*4 mm hot-dip galvanized angle code, and the length of the angle code is 50 mm.

[0009] In some embodiments of the present application, the installation cross beam is an 8# hot-dip galvanized channel steel, and the angle code and the installation cross beam are fully welded.

[0010] Compared with the prior art, the present utility model has the following characteristics and beneficial effects:

[0011] The present utility model uses an I-shaped steel beam to provide support for the installation of the conversion layer. The angle code is fixed on the lower flange plate of the I-shaped steel beam through a C-shaped fastener, and the installation cross beam is welded on the angle code, which can avoid directly welding the installation cross beam to the I-shaped steel beam and protect the fireproof layer of the I-shaped steel beam. By opening a plurality of installation holes on the installation cross beam, it is convenient to install the through wire suspender. The present utility model can avoid the stress of the lightweight floor slab while protecting the fireproof layer of the steel structure, with a fast installation speed, and good effects can be achieved by popularizing and using it.
