Definitions
- U S Cl 52/638 52/646 182/178 Load bearing scaffolding comprises uprights con- [51] I04g 1/14 nected by bracing frames. Each frame comprises a [58] Fieid 638 cross-member releasably connectable to an adjacent 52/646 frame.
- the invention relates to scaffolding, inter alia for load-bearing, e.g. to scaffolding for strengthening framework.
- the invention relates to the kind embodied by stacked vertical uprights releasably interconnected by bracing frames.
- a problem with such scaffolding is to provide satisfactory bracing of the vertical uprights, and the bracing frames are used for this purpose.
- bracing frames provide greater rigidity than in conventional scaffolding, inter alia by opposing any horizontal deformation of the scaffolding.
- each bracing frame comprises at least one connecting cross-member having a free end comprising securing means adapted to provide a rigid connection releasable at least in horizontal directions between such free end and an adjacent bracing frame.
- a bracing frame of this kind which can be embodied by a horizontal cross-member and two associated skew cross-members to form a triangle, is light in weight, easy to handle and simple to position.
- each bracing frame is rigidly connected to the vertical uprights and to the adjacent bracing frame, rigidity is better (inter alia because horizontal forces are taken up) than in scaffoldings devoid of any direct connection between the bracing frames, as occurs in con ventional scaffolding with bracing frames.
- bracing frames can be engaged with a single vertical upright, thus making it possible to devise towers, spans, etc., of any shapes and sizes.
- the telescopic elements have lateral engaging means near their top end and are braced against one another by a follower frame having complementary engaging means adapted to cooperate with the main engaging means of the telescopic elements, each follower frame having at least one connecting cross-member, at least the free end of which has guide means adapted to provide a releasable connection, which is rigid at least in horizontal directions, between such free end and the bracing frame interconnecting the vertical uprights bearing the telescopic elements, whatever the position thereof and of the follower frame engaged with the telescopic elements.
- FIG. 1 is a view in elevation of scaffolding according to the invention
- FIG. 2 is a view to an enlarged scale of an important detail of the scaffolding of FIG. 1;
- FIGS. 3-5 are each views in elevation showing alternative forms of scaffolding according to the invention.
- FIG. 6 is a view in elevation showing an advantageous form of scaffolding according to the invention.
- FIG. 7 is a perspective view of the scaffolding shown in FIG. 6.
- FIG. 1 shows the bottom part of scaffolding embodied by stacked vertical uprights 1 having coupling means 2 enabling them to be stacked;
- the coupling means 2 can be embodied by providing at the bottom of each upright 1 a socket 2a adapted to extend around the top of the upright 1 immediately below.
- the two uprights 1 can be rigidly connected by means of a pin 2b (FIG. 2).
- each vertical upright 1 has lateral main engaging means 3, for instance, in the form of U members 3a secured, e.g. by welding, to the upright 1 and cooperating therewith to bound a passage 3b (FIG. 2.).
- the means 3 of each upright 1 take the form of four U members 3a disposed at to one another at the same level as one another.
- each frame 4 has a horizontal cross-member 5 whose two ends have complementary engaging means 6 adapted to cooperate with the main engaging means 3 of the upright 1.
- the means 6 can comprise a projection 6a engageable in the passage 3b bounded by the upright l and the U member 3a (FIG. 2).
- Each frame 4 also comprises two connecting cross-members 7 which are rigidly secured to the horizontal crossmember 5 and which cooperate therewith to form an isosceles triangle.
- the free ends of the two cross-members 7 are interconnected and have securing means 8 adapted to provide a releasable connection between the lastmentioned ends and the horizontal cross-member 5 of the adjacent frame 4.
- the means 8 can take the form of a yoke-like member 8a which rides on the corresponding horizontal cross-member 5 and which is n'gidly secured thereto by a pin 8b.
- the means 8 cooperate with a bottom horizontal cross-member 5 both ,of whose ends have complementary engaging means 6 adapted to cooperate with main engaging means 3 disposed laterally on vertical uprights 1 on which the adjacent overhead vertical uprights 1 of the scaffolding are engaged.
- the elements 3,, 6 are arranged similarly to the elements 3, 6.
- the means 2 are adapted to lock the system embodied by the means 3, 6; to this end, the means 3 are disposed near the top end of the upright l and the socket 2a is adapted to form an abutment opposing release of the means 6 from the means 3 of the adjacent upright 1 immediately below (FIGS. 1, 2 and 3).
- the means 3 can be positioned near the bottom end of the upright 1 (FIG. 4) or in the central part thereof (FIG. 5).
- the triangular frames 4 can be positioned either apex downwards, as in FIGS. 1, 2, 4 and 5, or apex upwards, as in FIG. 3.
- FIGS. 6 and 7 in which like reference numerals denote like elements, which Figures show the top of the scaffolding.
- the telescopic elements can, if necessary, be disposed at the bottom or even in a central part of the scaffolding.
- the elements 9 can be embodied by tubes sliding in the uprights 1, the tubes being positionable at various extensions by means of a system comprising apertures 10 and a pin 11; alternatively, in variants which are not shown, lifting facilities such as jacks or rams or the like can be used.
- Each element 9 has main abutment means 12 near its top end which are disposed laterally and which, like the corresponding means 3 of the uprights 1, can be embodied by U members 12a secured, e.g. by welding, to the particular telescopic element 9 concerned and which cooperate therewith to bound a passage 12b.
- the main engaging means 12 of each element 9 are embodied by 4U members 120 which are disposed at 90 to one another and at the same level as one another.
- the elements 9 are braced relatively to one another by a follower frame 13 comprising a horizontal crossmember 14, both of whose ends have complementary engaging means 15 adapted to cooperate with the means 12 of elements 9. and possibly being embodied by a projection 15a engaging in the passage 12b just described.
- the frame 13 also comprises two connecting cross-members 16 which are rigidly secured to the horizontal cross-member 14 and which cooperate therewith to form an isosceles triangle.
- the free ends of the two integers 16 are interconnected and are rigidly secured to a vertical cross-member 17 which extends and is secured to the horizontal cross-member 14.
- the vertical cross-member 17 is adapted to form guide means 18 adapted to provide a rigid but releasable connection between the member 17 and an element of the bracingframe interconnecting the vertical uprights bearing the particular telescopic elements 9 concerned, whatever the position thereof and of the follower frame 13 engaged with such elements.
- the corresponding frame 4 can comprise a vertical cross-member 19 which cooperates telescopically (internally or externally) with the member 17 of the frame 13.
- the guide means 18 take the form of a system of apertures 18a and a pin 18b, the apertures 18a being distributed at the same pitch as the holes 10 for varying the extended position of the elements 9.
- the only frames 4 which must have the vertical crossmember 19 are the ones below the follower frames 13, all the frames 4 can, if required, have the member 19, in which event the means 8 can be disposed near the bottom end of the member 19 and be embodied by a system comprising a yoke-like rider and a pin (FIG. 7).
- the scaffolding is devised from elements (mainly vertical uprights, bracing frames and follower frames) which are light in weight, easy to handle and simple to position; the scaffolding is rigidly braced near the vertical uprights and near the telescopic elements;
- the scaffolding can be embodied in a wide variety of forms (spans, towers) with dimensions adapted to the nature of the load to be borne (magnitude and distribution).
- each said bracing frame comprises at least one connecting cross member having an end comprising securing means adapted to be secured (at least in a horizontal direction) directly to an adjacent said bracing frame, at least some of said bracing frames comprising two skew connecting crossmembers which cooperate with a horizontal crossmember to form a triangle lying between immediately adjacent vertical uprights, said securing means being located at the corner of a triangle where said skew connecting cross-members meet.
- each said bracing frame comprises at least one connecting crossmember having an end comprising securing means adapted to be secured (at least in a horizontal direction) to an adjacent said bracing frame, and telescopic elements adapted to take up a number of extended positions relatively to the vertical upright, characterized in that the telescopic elements have lateral engaging means near their top end, follower frames arranged to brace the telescopic elements against one another, said follower frames having complementary engaging means adapted to cooperate with said lateral engaging means of the telescopic elements, each follower frame having atleast one connecting cross-member, having an end securable (at least in horizontal direction) to the bracing frame interconnecting the vertical uprights bearing the telescopic elements,
- the bracing frame comprises a vertical cross-member which cooperates telescopically with the vertical crossmember of the follower frame, the guide means being embodied a system of apertures and pins, the apertures being distributed at the same pitch as the apertures for varying the extension of the telescopic elements.
