Description
- The invention relates to a scaffold, provided with uprights and girders.
- Such a scaffold is known from practice and is marketed by applicant. In the known scaffold system, tubular uprights and tubular girders are detachably coupled to each other by means of scaffold tube clamps, for instance cross and/or pivot couplings. A disadvantage of this system is, that building the scaffold with such scaffold tube clamps is relatively cumbersome and hence time consuming. In particular a desired positioning of the different parts relative to each other can form a problem.
- From practice, also a so-called system scaffold is known which can be built up and taken down relatively rapidly. Such a system scaffold is provided with uprights which are each provided, at fixed distances from each other, with integral connecting rings with eyelets. Generally, the mutual distance mentioned between such connecting rosettes is 50 cm. At end faces, the girders of such a system scaffold are provided with hooks for hooking the girders to the eyelets of the connecting rings of the uprights. Through this design, the uprights and girders can relatively rapidly and firmly be detachably interconnected during the building of the scaffold.
- A disadvantage of the system scaffold mentioned is that the girders are only connectable to the uprights at fixed heights. While erecting and building the scaffold, this may lead to various problems. In the first place, generally, various objects are present on the ground where the scaffold is to be erected, for instance pipes, cables, pumps, vessels, tools, building materials and/or other objects. The height of such objects varies from building site to building site. Therefore, each time, a lower scaffold floor is preferably positioned at a different height, depending on the height of objects present under it. However, in the system scaffold known from practice, this is not possible as, each time, only a limited number of hooking positions are available, at heights of 60 cm, 100 cm, etc.
- Moreover, the heights of the other scaffold floors are also fixed, for instance at 100 cm, 150 cm, 200 cm, etc. In some cases, this is unpractical, for instance when there is an obstacle present at such a height, such as a roof gutter, a casement or a different protrusion of, for instance, a nearby building.
- The object of the present invention is to eliminate the drawbacks of the scaffold while maintaining its advantages. In particular, the invention contemplates a scaffold which can be erected and disassembled relatively easily and rapidly, while the girders can yet be coupled at any arbitrary position on the uprights.
- To this end, according to the invention, the scaffold is characterized in that at at least one end face, each girder is integrally provided with a coupling means for detachably coupling the girder to a smooth part of an upright.
- Thus, the scaffold can be built up in a simple manner, while the girders can rapidly be coupled to the uprights at a desired height. In this manner, a base for the scaffold floor can be set up at a desired height on a building site, in particular via the following steps, to be carried out in suitable order:
- a) uprights are erected at desired positions; and
- b) at the desired height, girders are coupled to smooth parts of the uprights via the respective coupling means. Then, the base can be provided with, for instance, scaffold floor parts to serve as a bottom scaffold level.
- As the girders are connectable to the uprights at arbitrary positions, the girders can be positioned at the exact desired height. Moreover, the girders are already integrally provided with one or two coupling means, so that coupling to the upright can be carried out relatively rapidly. Building the scaffold can be further simplified by using girders of a limited number of fixed length dimension.
- It is noted that the term “smooth” should be understood in a relatively broad sense. In particular, a smooth upright part should be understood to mean that that upright part is substantially not provided with certain protruding parts, such as, for instance, the integral connecting rosettes mentioned.
- Further elaborations of the invention are described in the subclaims. Presently, the invention will be further clarified with reference to two exemplary embodiments and the drawing. In the drawing:
-
FIG. 1 shows a top plan view of a first exemplary embodiment of the invention; -
FIG. 2 shows a side view of the girder of the top plan view represented inFIG. 1 ; and -
FIG. 3 shows a front view, represented in perspective, of a second exemplary embodiment of the invention. -
FIG. 1 shows a part of a scaffold which is provided with twouprights 1 between which agirder 2 has been provided. In the side view of thegirder 2 represented inFIG. 2 , the positions of theuprights 1 are drawn in interrupted lines. As shown inFIGS. 1 and 2 , thegirder 2 is integrally provided at bothend faces 3 with coupling means 4 for detachably coupling thegirder 2 to smooth parts of theuprights 1. Thus, thegirder 2 is distinguished from girders of a system scaffold known from practice, which system girders are only provided at ends with hooks for hooking those girders to rosettes of uprights. Such system girders cannot be coupled to smooth tube parts. - As the
girder 2 according to the invention can be coupled to smooth parts of anupright tube 1, thegirder 2 can be connected to the upright 1 at any desired height, at least if the upright 1 is of completely smooth design. In addition, thegirder 2 provided by the invention can, for instance, be used in combination with the system scaffold upright mentioned. In that case, thegirder 2 can be simply coupled by its coupling means 4 to the smooth upright parts extending between the rosettes. - As shown in
FIGS. 1 and 2 , each coupling means comprises atube clamp 4 to be detachably connected to a smooth tube part. Via an integral connectingbody 5, eachtube clamp 4 is integrally connected to thegirder 2. Eachclamp 4 is built up analogously to half cross couplings for scaffold tubes known from practice and comprises afirst clamp part 4 a attached to the respective connectingbody 5 to which clamp part asecond clamp part 4 b is hingedly coupled by means of a hingedjoint connection 8. At a free end, eachsecond clamp part 4 b is provided with amovable wedge 7 for securing thatclamp part 4 b to aclamp lip 9 of thefirst clamp part 4 a when theclamp parts clamp parts wedge 7 such that thoseclamp parts - As shown in the Figures, a cylindrical part of each
connecting body 5 extends into thegirder 2. The cylindrical part of each connecting body fits into thegirder 2 with relatively little or no clearance. As a result, theconnecting bodies 5 can be firmly attached to thegirder 2, for instance by means of a glued and/or welded joint. Moreover, each connectingbody 5 can be firmly connected to thegirder 2 by means of thermal clamping. Thegirder 2 is then heated before the closely fitting connectingbodies 5 are slid into thegirder 2. After cooling down and an attendant diameter reduction of thegirder 2, thegirder 2 can then very firmly clasp theconnecting bodies 5. Preferably, each connectingbody 5 is of substantially solid design, so that the body is relatively firm, rigid and strong. Moreover, each connectingbody 5 is designed such that after assembly eachend face 3 of thegirder 2 is at a relatively small distance L from the outer side of the oppositely located upright 1. Preferably, this distance L is, for instance, smaller than approximately 5 cm. - As shown in
FIG. 2 , thetube clamp 4L of thegirder 2 represented on the left hand side is located at an underside of a horizontal intersecting plane H, which plane H intersects thegirder 2 along its central axis. Conversely, thetube clamp 4R represented on the right hand side is located on an opposite, upper side of that intersecting plane H. This offers the important advantage that two of thesegirders 2 can extend at the same height when the girders are fitted to one upright 1. This is further described hereinbelow with reference toFIG. 3 . Moreover, each connectingbody 5 extends for a relatively large part at the same side of the intersecting plane H as the coupling means 4 connected to that connectingbody 5. Further, the connecting bodies 6 of thegirder 2 are each formed such that between each connectingbody 5 and the oppositely located upright 1 sufficient space S exists for a part of a coupling means 4 of anothergirder 2 to be coupled at substantially the same height to that upright 1 (seeFIG. 3 ). To that end, in the present exemplary embodiment, theupper side 6L of the lefthand connecting body 5L runs diagonally to thetube clamp 4 connected thereto. Theunderside 6R of the righthand connecting body 5R also runs diagonally to therespective tube clamp 4. -
FIG. 3 shows twogirders 2 coupled by the respective integral tube clamps 4 to anupright 1. The two tube clamps 4 of these girders are clamped to the upright at abutting positions. Theclamp 4L of thegirder 2L represented on the left hand side in the Figure is located at an underside of a horizontal intersecting plane, which plane intersects the central axes of the twogirders 2. Theclamp 4R of theright hand girder 2R is located at the opposite side of that intersecting plane. Due to the positions of theclamps 4 with respect to therespective girders 2, bothgirders 2 extend at the same height. With a number of thegirders 2 anduprights 1 represented, the system represented inFIG. 3 can be extended to a scaffold wherein, each time, a pair ofgirders 2 are coupled at the same height to an upright. This is advantageous, as, in this manner, thegirders 2 can for instance provide one horizontal bearing surface for fitting floor parts (not shown) thereon at the same height. The floor parts can then extend in various directions from and/or over thegirders 2. Moreover, as the distance L between theupright 1 and eachgirder 2 is relatively small, such floor parts can extend relatively close to the upright, so that no or only relatively narrow slits occur between the upright and the floor parts. - The connecting
body 5 of eachgirder 2 allows theclamp 4 of theother girder 2 to be attachable to and detachable from theupright 1. This is achieved through the shape described of each connecting body, and in particular in that the connectingbody 5 of eachgirder tube clamp body 5. - It is self-evident that the invention is not limited to the exemplary embodiments described. Various modifications are possible within the framework of the invention as set forth in the following subclaims.
- For instance, the tube clamps 4 of the
girder 2 can touch the horizontal intersecting plane H and/or be located at the respective side at a certain distance from that intersecting plane H. - Further, each coupling means 4 of the
girder 2 can be designed in different manners, for instance as half cross coupling, half-pivot coupling or the like. - In addition, both coupling means 4 of each
girder 2 can be located on opposite sides or, conversely, on the same side of the intersecting plane H mentioned, horizontal after assembly. - Further, the scaffold can be provided with various types of scaffold floors, for instance floors provided with floor parts which can be placed on girders and/or floor parts provided with hooks for hooking those floor parts to girders, for instance system decks.
- In addition, uprights of the scaffold can for instance be connected to each other by end faces, for instance by means of “tube-lock”-couplings marketed by applicant.
- Further, the scaffold can also be provided with different types of girders, such as girders which are not integrally provided with tube couplings, system girders comprising hooking means to be hooked to system uprights and/or other types of girders.
