Fastening tubular scaffold falsework

Abstract

The invention relates to a fastener type formwork bracket for a steel pipe scaffold. The bracket is 10 spans in the longitudinal direction and 6 spans in the transverse direction, and is loaded in the range of 5 spans x 5 spans; the loaded region is 2 spans outside one side in the longitudinal direction, while 3 spans outside the other side; the loaded region is 1 span outside one side in the transverse direction, while the other side is not spanned; and the ratio of the height to the width of the bracket is 1.44. The height of the bracket is 8.15 meters, the step pitch of upright rods is 1.49 meters, the longitudinal pitch of the upright rods is 0.9 meter, the transverse pitch of the upright rods is 0.94 meter, the bracket is built by using phi 48 x 3.5 steel pipes, and joints of the steel pipes are connected by fastening pieces. The upper part of the bracket is provided with phi 48 x 3.5 dual steel pipes which are supported by an adjustable supporting base and are used as main girders for supporting the formwork, the upright rods of the bracket are inserted into the bottom of the adjustable supporting base to fix the adjustable supporting base, the upper surface of the adjustable supporting base is adjusted to 0.5 meter on the upper layer of a topmost transverse pipe of the bracket, and the upright rods extend 0.3 meter out from the adjustable supporting base and are adjusted within the range of 0.3 meter. The fastener type formwork bracket for the steel pipe scaffold has a safe and steady structure and is convenient to build and dismantle.

Description

technical field [0001] The invention relates to a formwork support for a construction site, in particular to a fastener type steel pipe scaffold formwork support. Background technique [0002] At present, the fastener-type steel pipe scaffold formwork supports used in construction sites do not have a series of erection structure dimensions, no accurate design regulations, no restrictions on the critical load of the fastener-type steel pipe scaffold formwork supports, and no one-to-one correspondence between the series of formwork support erection structures. critical load requirements. On-site erection based on experience, on the one hand, causes waste of materials and increases cost, on the other hand, causes potential safety hazards, and some even cause major safety accidents. Contents of the invention [0003] The object of the present invention is to provide a fastener-type steel pipe scaffold formwork support with reasonable structural size, and provide the correspon...
