Abstract
The utility model discloses a kind of steel pipe frame construction stair, comprise double-pole scaffold (1), between double-pole scaffold (1), be erected with obliquely monomer stair (5), described monomer stair (5) are comprised of hound (9) and the stair step (4) that is fixed on evenly and at intervals on hound (9), in monomer stair (5) both sides, be provided with foot guard plate (2), hand rail (7) is arranged on double-pole scaffold (1) abreast with monomer stair (5), after overlapping, forms stair in a zigzag between levels monomer stair (5) by scaffold floor (3).The utility model not only simple in structure, set up conveniently, safe and reliable, convenient operation personnel walking, and can reusing after dismounting.
Description
Technical field
The utility model relates to a kind of steel pipe frame construction stair, belongs to technical field of building construction.
Background technology
At present, in building construction process, the stair aisle of operation layer is often occupied by the vertical rod in this layer of support system and drawknot bar, and constructor cannot normally walk at all on this stair aisle, the other erection construction stair on the scaffold in agent structure outside of therefore having to.Yet, existing scaffold stair are normal adopts two short steel pipes to be buckled on tilting steel pipe, then on two short steel pipes, boarding is fixedly made, and this scaffold stair are not only built cumbersome, and between plank and steel pipe, lacks reliable fixed form and (generally adopt plank kerf, with iron wire winding plank and steel pipe, fix again), while causing the upper and lower cat ladder of constructor, plank is fixing insecure, has potential safety hazard, and application life is short, be difficult to recycle.
Utility model content
The purpose of this utility model is, provide a kind of simple in structure, build quick, safe and reliable, and can have enough to meet the need use steel pipe frame construction stair, to overcome prior art deficiency.
The technical solution of the utility model: a kind of steel pipe frame construction stair, comprise double-pole scaffold, between double-pole scaffold, be erected with obliquely monomer stair, described monomer stair by hound and the stair step being fixed on evenly and at intervals on hound form, in monomer stair both sides, be provided with foot guard plate, hand rail and monomer stair are arranged on double-pole scaffold abreast, after overlapping, form stair in a zigzag between levels monomer stair by scaffold floor.
Described monomer stair comprise the rectangular frame being welded by angle steel, are welded with reinforcing bar in rectangular frame crisscrossly, are welded with checkered steel plate on reinforcing bar, and rectangular frame two ends are welded with joint steel pipe symmetrically.
Between described monomer staircases and handrails railing, be provided with close order safety net.
Between described monomer stair and stair step, adopt cruciform fastening for falsework to be fixedly connected with.
Owing to adopting technique scheme, construction stair of the present utility model are set up between double-pole scaffold, and the main member of these construction stair all adopts cruciform fastening for falsework to be connected with double-pole scaffold, and not only fixation is reliable, and dismounting is very convenient.Simultaneously on construction stair, be provided with foot guard plate and close order safety net, effectively prevent that material on stair, instrument, foreign material tenesmus from wounding walking personnel, ensure constructor's safety.Therefore, the utility model not only simple in structure, set up conveniently, safe and reliable, convenient operation personnel walking, and can reusing after dismounting.

Description of reference numerals: 1-double-pole scaffold, 2-foot guard plate, 3-scaffold floor, 4-stair step, 5-monomer stair, 6-base, 7-hand rail, 8-cruciform fastening for falsework, 9-hound, the close order safety net of 10-, 11-rectangular frame, 12-reinforcing bar, 13-joint steel pipe, 14-checkered steel plate.
The specific embodiment
In order to make the utility model object, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
Referring to Fig. 1, a kind of steel pipe frame construction stair of the present utility model, comprise double-pole scaffold 1, in order to improve the rigidity of double-pole scaffold 1, can bridging be set in the periphery of double-pole scaffold 1, it arranges standard and implements according to < < building operations fastener type steel pipe scaffold technical specification of security > > (JGJ130-2011), then between double-pole scaffold 1, set up obliquely monomer stair 5, described monomer stair 5 are comprised of hound 9 and the stair step 4 that is fixed on evenly and at intervals on hound 9, in monomer stair 5 both sides, be provided with foot guard plate 2, prevent the material on stair, instrument, walking personnel are wounded in foreign material tenesmus, hand rail 7 is arranged on double-pole scaffold 1 abreast with monomer stair 5, and hand rail 7 is 1200mm with the spacing of monomer stair 5, after overlapping, forms stair in a zigzag between levels monomer stair 5 by scaffold floor 3.Referring to Fig. 2～3, described monomer stair 5 comprise the rectangular frame 11 that the angle steel by 40 * 40 * 3mm is welded, at interior crisscross the reinforcing bar 12 that is welded with of rectangular frame 11, on reinforcing bar 12, be welded with checkered steel plate 14, rectangular frame 11 two ends are welded with the joint steel pipe 13 of φ 48.3 * 3.6mm symmetrically; Referring to Fig. 4, on joint steel pipe 13, offer groove 15, the angle steel on rectangular frame 11 is snapped in groove 15 and welded with joint steel pipe 13.In order to improve the barrier propterty of construction stair, between monomer stair 5 and hand rail 7, be provided with close order safety net 10.In addition, between monomer stair 5 and stair step 4, adopt cruciform fastening for falsework 8 to be fixedly connected with, the handling of convenient construction stair.Monomer stair 5 of the present utility model are set up between double-pole scaffold 1, and these monomer stair 5 adopt cruciform fastening for falsework 8 to be connected with double-pole scaffold 1, and not only fixation is reliable, and dismounting is very convenient.Simultaneously on construction stair, be provided with foot guard plate 2 and close order safety net 10, effectively prevent that material on stair, instrument, foreign material tenesmus from wounding walking personnel, ensure constructor's safety.Therefore, the utility model not only simple in structure, set up conveniently, safe and reliable, convenient operation personnel walking, and can reusing after dismounting.
