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; no additional span exists outside a loading area; the height-width ratio of the formwork support is 4.07 while the height of the formwork support is 8.15m; and the pace of a vertical upright is 0.62m and the longitudinal spacing of the vertical upright is 0.4m while the horizontal spacing thereof is 0.4m. Steel pipes with a diameter of 48 multiplied by 3.5 are used for setting up the formwork support and 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 0.5m and the section of the adjustable bracket, extending out of the vertical upright, is 0.3m and adjusted within 0.3m. The buckled type steel pipe scaffold formwork support has safe and stable structure and convenient assembly and disassembly.

Description

Buckled type steel pipe scaffold formwork support with large height-width ratio
Technical field
The present invention relates to the falsework that a kind of building site is used, especially a kind of buckled type steel pipe scaffold formwork support.
Background technology
The buckled type steel pipe scaffold formwork support of building site use at present, the physical dimension of setting up that does not have series, there is not design code accurately, do not have contacting piece formula steel pipe scaffold template stand critical load to limit, do not have the series mask support to set up structure critical load requirement one to one.Set up by rule of thumb at the scene, on the one hand, causes the waste of material cost to increase, and on the other hand, causes potential safety hazard, have in addition serious accident takes place.
Summary of the invention
The object of the present invention is to provide a kind of buckled type steel pipe scaffold formwork support, and provide corresponding critical load, make the steel pipe scaffold template stand economical rationality, safe and applicable with Rational structure size.
The present invention realizes above-mentioned purpose like this:
A kind of buckled type steel pipe scaffold formwork support comprises pole steel tube, vertical equity bar and transverse horizontal bar; Node connects with the malleable cast iron fastener, and support top is by the girder of 48 * 3.5 pairs of steel pipes of adjustable bracket jacking Φ as a flask board, and adjustable bracket bottom is inserted in the rack rod steel pipe fixing; Support vertical 5 is striden, and horizontal 5 stride, and strides 5 * 5 stride in the scope and to load; The outer nothing of loading zone adds strides; The support depth-width ratio is 4.07.
By adjustable bracket upper surface to pole steel tube bottom surface distance, i.e. the high 8.15m of frame, adjacent vertical equity bar or adjacent transverse horizon bar axial line distance, i.e. vertical rod step pitch 0.62m, pole steel tube longitudinal pitch 0.4m, pole steel tube horizontal spacing 0.4m.
Adjustable bracket upper surface is to the upper lateral tube epithelium 0.5m of support, and adjustable bracket stretches out pole steel tube length and is not more than 0.3m.
This buckled type steel pipe scaffold formwork support structural safety is firm, and supporting structure is simple, takes and tears open conveniently, steel pipe scaffold template stand economical rationality, safe and applicable.

The specific embodiment
A kind of buckled type steel pipe scaffold formwork support comprises pole steel tube 4, vertical equity bar 3 and transverse horizontal bar 5; Node connects with malleable cast iron fastener 6, and support top is by the girder of 48 * 3.5 pairs of steel pipes of adjustable bracket 1 jacking Φ 2 as a flask board, and adjustable bracket 1 bottom is inserted in the rack rod steel pipe 4 fixing.Support vertical 5 is striden, and horizontal 5 stride, and strides 5 * 5 stride in the scope and to load, and loading zone is outer not to be had to add and strides; Support depth-width ratio=8.15 ÷ (5 * 0.4)=4.07; The bar of sweeping the floor is the support lower crosspiece, and D is the bar height of sweeping the floor.
To pole steel tube bottom surface distance, promptly the high C of frame is 8.15m by adjustable bracket upper surface, adjacent vertical equity bar or adjacent transverse horizon bar axial line distance, be that vertical rod step pitch E is 0.62m, pole steel tube longitudinal pitch A is 0.4m, and pole steel tube horizontal spacing B is 0.4m, and the bar height D that sweeps the floor is 0.2m.
Adjustable bracket 1 upper surface is 0.5m to the upper lateral tube epithelium of support apart from F, and adjustable bracket 1 stretches out pole steel tube 4 length and is not more than 0.3m (among the figure shown in the G).
Test is shown in Fig. 4-6, and this buckled type steel pipe scaffold formwork support is through jack 11 loadings, top reaction frame 7 girders, reaction frame returns back to top load is reached distribution beam 9, distribution beam 9 reaches i iron 10 with load, and i iron 10 reaches the two steel pipes 2 of support with load, realizes the support loading test.Determine the every square meter 167.18kN of critical load, average single vertical rod critical load 18.57kN through loading test.
