Problems solved by technology

[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 material waste and increases cost, on the other hand, causes safety hazards, and some even cause major safety accidents

Embodiment Construction

[0016] A fastener-type steel pipe scaffold formwork bracket, including a vertical steel pipe 4, a longitudinal horizontal rod 3 and a horizontal horizontal rod 5; the nodes are connected by malleable cast iron fasteners 6, and the upper part of the bracket is supported by an adjustable bracket 1 Φ48×3.5 double steel pipes ( 2) As the main beam of the supporting formwork, the bottom of the adjustable bracket 1 is inserted into the steel pipe 4 of the support vertical rod and fixed. The support has 5 spans in the vertical direction and 5 spans in the horizontal direction, and is loaded within the range of 5 spans × 5 spans. Vertical scissors braces are installed every four rows of vertical poles on the facades around the periphery of the loading area. The joints are fastened with fasteners, and the angle between the vertical scissors braces and the horizontal bars of each facade around the periphery of the loading area is 48 degrees to 50 degrees, and the bottom span of the sciss...

Abstract

The invention relates to a buckled type steel pipe scaffold formwork support, wherein five spans are available longitudinally and also horizontally and loading is conducted within the range of 5 spans multiplied by 5 spans; each vertical face around the periphery of a loading area is provided with a vertical cross strut at every four rows of vertical uprights and the cross strut is arranged close to joints and the junction of the cross strut and a cross rod or the vertical upright is fastened by a fastener; the height-width ratio of the formwork support is 2.71 while the height of the formwork support is 8.15m; and the pace of the vertical upright is 0.9m and the longitudinal spacing of the vertical upright is 0.65m while the horizontal spacing thereof is 0.6m. Steel pipes with a diameter of 48 multiplied by 3.5 are used for setting up the formwork support and the joints are connected with a fastener respectively. The upper part of the formwork support supports the double steel pipes with a diameter of 48 multiplied by 3.5 by an adjustable bracket to be used as main beams for supporting formworks. The bottom of the adjustable bracket is inserted into the vertical upright of the formwork support for fixing and the distance from the upper surface of the adjustable bracket to the upper surface of the topmost transverse pipe of the support is 0.55m and the section of the adjustable bracket, extending out of the vertical upright, is 0.32m and adjusted within 0.32m. The buckled type steel pipe scaffold formwork support has safe and stable structure and convenient assembly and disassembly.

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...
