The height of the support is 8.15m, step pitch vertical rods is 1.233m, longitudinal direction spacing of the vertical rods is 0.9m, transverse direction spacing of the vertical rods is 0.94m, phi48*3.5 steel pipes are used for building, and each node is connected by fastener. Adjustable bracket holder and top phi48*3.5 double-steel pipe is used as main beam for supporting the formwork at upper part of the support, support vertical rods are inserted in bottom of the adjustable bracket holder for fixing, the distance from upper surface of the adjustable bracket holder to upper surface of the uppermost longitudinal rod of the support is 0.55m, the vertical rods steel pipes are extended from the adjustable bracket holder for 0.32m and are adjusted in range of 0.32m. The fastener type steel pipe scaffold template formwork of the present invention has safe and firm structure, and is convenient for assembling and disassembling.
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 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 8 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 1 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 1.44.
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 1.233m, pole steel tube longitudinal pitch 0.9m, pole steel tube horizontal spacing 0.94m.
The distance that adjustable bracket upper surface to support is gone up vertical equity bar upper surface most is 0.55m, and the length that adjustable bracket stretches out pole steel tube is not more than 0.32m.
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 8 is striden, and horizontal 6 stride, and strides 5 * 5 stride in the scope and to load, and the outer vertical side 2 of loading zone is striden, and opposite side 1 is striden; The outer horizontal side 1 of loading zone is striden, and opposite side does not have to add strides; Support depth-width ratio=8.15 ÷ (6 * 0.94)=1.44; 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 1.233m, 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 0.2m.
What adjustable bracket 1 upper surface to support was gone up vertical equity bar 3 upper surfaces most is 0.55m apart from F, and the length that adjustable bracket 1 stretches out pole steel tube 4 is not more than 0.32m (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 40.44kN of critical load, average single vertical rod critical load 23.76kN through loading test.
