Abstract

The utility model relates to a steel-tube full scaffold of fastener type, The scaffold has 4 longitudinal strides and 4 transversal strides, loads in a range of 4 stride*4 strides and has no added strides outside a loading region, a support has a depth-width ratio of 1.6 and a height of 8.0 m; the step pitch of vertical bars is 1.47 m, the longitudinal distance between the vertical bars is 1.27 m, and the transversal distance between the vertical bars is 1.2 m; the scaffold is erected by the steel tubes with the diameter of 48*3.5, and all joints are connected by fasteners; transversal bars at the top of the scaffold directly bear upper loads, and an upper transversal bar is longitudinally arranged in the middle between the adjacent vertical bars. The steel-tube full scaffold of fastener type has safe and stable structure and is convenient erect and dismount.

Description

The full hall of a kind of fastener type steel pipe scaffold

Technical field

The utility model relates to the fastener type steel pipe scaffold that a kind of building site is used, the full hall of especially a kind of fastener type steel pipe scaffold.

Background technology

The full hall of the fastener type steel pipe scaffold of building site use at present, the physical dimension of setting up that does not have series, do not have design code accurately, do not have the full hall of a contacting piece formula steel pipe scaffold critical load to limit, do not have full scaffolding structure critical load requirement one to one of series.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.

The utility model content

The purpose of this utility model is to provide a kind of full hall of fastener type steel pipe scaffold with Rational structure size, and provides corresponding critical load, makes the economical rationality of the full hall of fastener type steel pipe scaffold, safe and applicable.

The utility model is to realize above-mentioned purpose like this:

The full hall of a kind of fastener type steel pipe scaffold comprises pole steel tube, vertical equity bar and transverse horizontal bar; Node connects with the malleable cast iron fastener, and upper load is directly born by the transverse horizontal bar in the scaffold top, the upper lateral horizon bar longitudinally between adjacent pole steel tube the middle part arrange one; Scaffold vertical 4 is striden, and horizontal 4 stride, and strides 4 * 4 stride in the scope and to load; The outer nothing of loading zone adds strides; The support depth-width ratio is 1.6.

Scaffold top cross horizon bar epithelium is 7.7m to pole steel tube bottom surface distance, scaffold upright rod steel pipe end face on earth identity distance from, be the high 8.0m of frame, adjacent vertical equity bar or adjacent transverse horizon bar axial line distance, be vertical rod step pitch 1.47m, pole steel tube longitudinal pitch 1.27m, pole steel tube horizontal spacing 1.2m.

The full hall of this fastener type steel pipe scaffolding structure safety and firmness, supporting structure is simple, takes and tears open conveniently, steel pipe scaffold template stand economical rationality, safe and applicable.

The specific embodiment

The full hall of a kind of fastener type steel pipe scaffold comprises pole steel tube 3, vertical equity bar 2 and transverse horizontal bar 1; Node connects with malleable cast iron fastener 4, and upper load is directly born by the transverse horizontal bar in the scaffold top, the upper lateral horizon bar longitudinally between adjacent vertical rod the middle part arrange one.Scaffold vertical 4 is striden, and horizontal 4 stride, and strides 4 * 4 stride in the scope and to load, and loading zone is outer not to be had to add and strides; Support depth-width ratio=7.7 ÷ (4 * 1.2)=1.6; The bar of sweeping the floor is the support lower crosspiece, and D is the bar height of sweeping the floor.

Scaffold top cross horizon bar epithelium is 7.7m to pole steel tube bottom surface distance, the scaffold upright rod end face on earth identity distance from, be the high 8.0m of frame, adjacent vertical equity bar or adjacent transverse horizon bar axial line distance, be that vertical rod step pitch E is 1.47m, pole steel tube horizontal spacing A is 1.2m, and pole steel tube longitudinal pitch B is 1.27m, and the bar height D that sweeps the floor is 0.35m.

Scaffold top cross horizon bar epithelium is 7.7m to the pole steel tube bottom surface apart from F, and support upper lateral horizon bar epithelium is 0.3m (shown in the figure) to the pole steel tube end face apart from G.

Test is shown in Fig. 4-6, the full hall of this fastener type steel pipe scaffold is through jack 9 loadings, top reaction frame 5 girders, reaction frame returns back to top load is reached distribution beam 7, distribution beam 7 reaches i iron 8 with load, i iron 8 reaches support top cross horizon bar 1 with load, realizes the loading test of full hall scaffold.Determine the every square meter 12.42kN of critical load, average single vertical rod critical load 12.11kN through loading test.
