Abstract
Platform flooring for scaffolding should be designed so that it is as light as possible, can be produced from only a few components, is effective in use and can be securely assembled. In addition, its width should be variable. The invention calls for the platform flooring to be made of extruded-drawn hollow sections (1) which are connected to each other along the edges by a groove-and-tongue joint (11, 14). Also included in the system are hollow-section edging sections (1', 1'') which make a specially designed support section unnecessary.
Description
The present invention relates to a kind of especially platform unit of scaffold etc. of support that is used for, wherein, platform unit is made up of the monolithic hollow type bar that at least two longitudinal sides at them detachably are connected to each other together.
The platform unit that is used for scaffold etc. by known this class of DE-OS4323381A1.Wherein, the hollow type bar is slotted along total length, in addition they be designed to can be nested against one another and have unique a kind of section bar just enough by means of these grooves so that can form complete platform unit with the end member that matches.Be provided with some ripples, they are used to improve shape stability and are connected adjacent hollow type bar.
Obviously, the requirement when assembling of this known structure is riveted together adjacent hollow type bar mutually and obtains necessary shape stability, because otherwise because the inevitable wall thickness that increase relevant section bar greatly of the groove of this perforation.These ripples without exception inwardly so that make the suitably stop of adjacent hollow type bar, therefore they can not cut any ice for positional stability when a plurality of platform unit stacking.Also can not any a plurality of hollow type bars are together nested against one another, and can only be two all the time.
Thereby the objective of the invention is, provide a kind of by taking simple measures to make the platform unit of the described type of the more reliable preface of work, and be designed to cancel connector additional between the hollow type bar, however, platform unit still can fit together dimensionally stable; A kind of stacking servicing unit that is used for platform unit is desirable equally.In addition, the quantity of parallel hollow type bar also should be arbitrarily, and therefore the favourable width of this hollow type bar needn't decide according to the width of platform unit.
By the present invention for reaching this purpose, it is section bar by the extrusion molding that the hollow type bar is designed to seal, the side that they are parallel to the mutual splicing of supporting frame longitudinal side is shaped on a groove of the perforation of parallel sided therewith in a side of this hollow type bar, and be shaped on the protuberance of a shape and groove complementation at opposite side, at this moment, the groove that two adjacent hollow type bars can be by one of them hollow type bar and another hollow type bar are placed in protuberance in this groove and engage one another and be in the same place; In addition, the longitudinal side of supporting frame is same respectively to be made of a similar pieceable hollow type bar, but this hollow type bar forms on that side of supporting frame external boundary and only is provided with a preferably smooth side, and only is equipped with a groove or a protuberance on another faces that side of adjacent hollow type bar; And best, the horizontal side of platform unit is made up of a support sections of putting bed board, and this support sections is used for platform unit is fixed on remaining scaffold.
Do not have professional knowledge can assemble by platform unit of the present invention yet, and can engage securely with the coupling device of protuberance, therefore can be assembled into a stable face of walking by very light extrusion molding spare by groove by hollow type bar one by one.These members both needn't connect with screw also needn't rivet, and can rabbet together mutually with any amount; Because the mating face is tight,,, can guarantee that also platform unit has high supporting capacity in this way by the vertical catch of a large amount of decision modulus of section of each hollow type bar even for this light weight section.
Adjacent hollow type bar in fact seamlessly connects and can for example realize like this,, is integrally formed vertical with a parallel filler rod at protuberance that is, and it can insert one and deep-cut in the secondary groove parallel in the groove lower wall.This design had both improved bending stiffness longitudinally, and had improved the horizontal shape stability of platform unit.
The hollow type bar can be designed to each side basically identical substantially wall thickness, also includes the zone of groove and protuberance.A kind of like this design is favourable on technology, because avoided thermal stress during fabrication as much as possible, and just can produce this thermal stress when wall thickness has big sudden change.
Practical especially is, form that hollow type bar of supporting frame longitudinal side as the border, they as the cover-up surface of foot-operated face on and be in it on the bottom surface of homalographic of relative position, respectively be provided with at least one ripple, the ripple vicinity also is parallel to that smooth side, especially, corrugated design in cover-up surface is a projection, and the corrugated design in the bottom surface is recessed, because in this way except improving stability, also created precondition for following way, that is, the size of ripple can be designed as, and passes through mutual immediate bed board when platform unit is stacked up and down, ripple is embedded mutually, and prevent that as the servicing unit of stacking platform unit from laterally moving each other.
If support sections is U or L-shaped section, and the hollow type bar is rested on the edge of a wing of the lower horizontal that is connected with the vertical web of U or L shaped material, then this platform unit can be by the type completion that conforms with purpose.In this case, the hollow type bar can be fixed on the support sections by their end to small part.Adjacent hollow profile is fixed on the support sections, and remaining is just put up, does so to meet the demands, especially under the situation of using the U-shaped section bar.
By platform unit of the present invention, those hollow type bars that constitute the platform unit longitudinal side can be designed to identically, or be designed to the mirror image symmetry; Under latter event, be preferably in the both sides of hollow type bar, respectively establish a groove or respectively establish a protuberance.
Adopt by platform unit of the present invention, can assemble out the platform unit of complete different in width with identical basic building block; In this way, add with storehouse management and only limit to a small amount of different member, and thereby be simplified.
