Description
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 adjustable bracket jacking 90mm * 90mm flitch as a flask board, and adjustable bracket bottom is inserted in the rack rod steel pipe fixing; Support vertical 10 is striden, and horizontal 6 stride, and strides 5 * 5 stride in the scope and to load; The outer vertical side 2 of loading zone is striden, and opposite side 3 is striden; The outer horizontal side 1 of loading zone is striden, and opposite side does not have to add strides, and the support depth-width ratio is 0.91.
By adjustable bracket upper surface to pole steel tube bottom surface distance, i.e. the high 5.15m of frame, adjacent vertical equity bar or adjacent transverse horizon bar axial line distance, i.e. vertical rod step pitch 1.49m, pole steel tube longitudinal pitch 0.9m, pole steel tube horizontal spacing 0.94m.
Adjustable bracket upper surface is to the upper lateral tube epithelium 0.5m of support, and adjustable bracket stretches out vertical rod length and is not more than 0.3m.
There is flitch seam 7 in 90mm * 90mm flitch, flitch seam 7 below pad 90mm * 40mm flitches 13, and seam is apart from pole steel tube 4 distances of shaft centers are from being 300mm recently, 90mm * 13 liang of nearest lateral extents of the adjustable bracket of end distance of 40mm flitch are 100mm.
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.

Among the figure: 1, adjustable bracket; 2,90mm * 90mm flitch; 3, vertical equity bar; 4, pole steel tube; 5, transverse horizontal bar; 6, malleable cast iron fastener; 7, flitch seam; 8, reaction frame; 9, fixing reaction frame steel pipe; 10, distribution beam; 11, i iron; 12, jack; 13,90mm * 40mm flitch.
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, support top is by the girder of adjustable bracket 1 jacking 90mm * 90mm flitch 2 as a flask board, at 90mm * 7 times pad 90mm * 40mm flitches 13 of 90mm flitch seam, seam is 300mm apart from nearest pole steel tube 4 axle center distance L, and 90mm * nearest lateral extent H of 13 liang of adjustable brackets of end distance of 40mm flitch is 100mm.
To pole steel tube bottom surface distance, promptly the high C of frame is 5.15m 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 1.49m, pole steel tube longitudinal pitch A is 0.9m, and pole steel tube horizontal spacing B is 0.94m, and the bar height D that sweeps the floor is 0.18m.
Test is shown in Fig. 5-7, this buckled type steel pipe scaffold formwork support is through jack 12 loadings, top reaction frame 8 girders, reaction frame returns back to top load is reached distribution beam 10, distribution beam 10 reaches i iron 11 with load, i iron 11 reaches support 90mm * 90mm flitch 2 with load, realizes the support loading test.Determine the every square meter 57.71kN of support critical load, average single vertical rod critical load 33.90kN through loading test.Flitch is at every square meter 42.89kN, begins cracking during average single vertical rod load 25.2kN, but begins unstability to reaching critical load to support, and flitch is destruction fully also.
