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 support, 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 support formwork, the bottom of the adjustable bracket 1 is inserted into the steel pipe 4 of the support vertical rod and fixed. The bracket has 5 spans in the vertical direction and 5 spans in the horizontal direction, loaded within the range of 5 spans × 5 spans, and there is no span increase outside the loading area; the height-to-width ratio of the bracket = 8.15÷(5×0.6) = 2.71; the sweeping rod is the lower cross bar of the bracket, D is the height of the sweeping rod.

[0017] The distance from the upper surface of the adjustable bracket to the bottom surface of the vertical steel pipe, that is, the height C is 8.15m, the dist...

Abstract

The invention relates to a fastener type steel pipe scaffold formwork support, which 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; there is no extra span outside the loading area; the height-to-width ratio of the support is 2.71. The height of the erection is 8.15m, the step distance of the pole is 0.9m, the vertical distance between the poles is 0.65m, and the horizontal distance between the poles is 0.6m. The upper part of the bracket is supported by an adjustable bracket Φ48×3.5 double steel pipe as the main beam of the supporting template, the bottom of the adjustable bracket is inserted into the vertical pole of the bracket and fixed, and the upper surface of the adjustable bracket is connected to the upper surface of the longitudinal horizontal rod (3) of the bracket. The distance is 0.55m, the adjustable bracket protrudes 0.32m from the pole, and can be adjusted within the range of 0.32m. The fastener-type steel pipe scaffold formwork bracket of the present invention has a safe and stable structure and is convenient to assemble and disassemble.

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...
