Sleeve type fixing device at corner of cantilever scaffold

Abstract

The invention discloses a sleeve type fixing device at the corner of a cantilever scaffold and relates to the field of building engineering. The sleeve type fixing device at the corner of the cantilever scaffold comprises a sleeve tool which comprises a main fixing part and a plurality of I-shaped steel sleeves. The main fixing part and the I-shaped steel sleeves are arranged on a same plane. The I-shaped steel sleeves are arranged in the shape of a sector and integrally arranged at one end of the main fixing part. An I-shaped inner cavity is formed in each I-shaped steel sleeve. A piece of I-shaped steel is inserted in each I-shaped steel sleeve and is connected with the corresponding I-shaped steel sleeve through an inserting connection bolt and fixed through an open pin. The sleeve type fixing device has the advantages that only the sleeve tool needs to be fixed on a cast-in-place floor, the using quantity of the I-shaped steel and the using number of embedded parts can be reduced, and labor cost caused by embedding and installing is reduced; installing efficiency of the cantilever I-shaped steel can be improved; the I-shaped steel is installed through the sleeve tool and is located on the same plane, the bottom ends of vertical rods of the scaffold are also on the same plane, stability of a cantilever scaffold body can be improved, and potential safety hazards can be reduced.

Description

Technical field [0001] The invention relates to the field of construction engineering, in particular to an operation method of a cantilever scaffold at a corner. Background technique [0002] At present, the cantilevered steel beams of the cantilevered scaffolding at the corners of the floor are generally arranged in a fan shape, that is, one I-beam perpendicular to the outside of the floor is arranged on both sides of the corner, and then the two I-shaped steel beams Several I-beams are arranged in a fan shape in the middle of the steel, and the above I-beams are respectively fixed. The specification JGJ130-2011 stipulates that the length of the fixed end of the cantilever beam should not be less than 1.25 times the length of the cantilever end. Because the I-beams arranged at the corners are dense and different in length, the fixed ends of the I-beams often cross each other The layout situation not only increases the number of embedded and fixed, but also due to the cross arra...

Problems solved by technology

The standard JGJ130-2011 stipulates that the length of the fixed end of the cantilever beam should not be less than 1.25 times the length of the cantilever end. Since the I-beams arranged at the corners are relatively dense and of different lengths, the I-beams at the fixed end often cross each other. Due to the layout situation, this not only increases the number of pre-embedded and fixed, but also due to the cross arrangement of I-beams, the height of the cantilevered scaffolding at the corner is different, which has a certain impact on the stability and safety of the scaffolding
