Definitions
- the present invention relates first of all to a framework for floors of scaffolding made up of a set of superimposed and nested floors, this frame comprising a vertical upright provided with nesting means allowing it to fit on the corresponding vertical upright of a underlying frame, this frame comprising a bracing of connection of said upright to a vertical hand provided with a locking means, this hand being able to engage laterally, by pivoting around said upright, and being locked, as soon as it stops, on the vertical upright of a similar neighboring frame of said floor.
- each bracing frame has at least one cross link having a free end provided with means for fastening arranged and arranged to secure, so removable and at least in horizontal directions, the the said free end with a bracing frame adjacent.
- Document DE 1 957 913 describes a frame for floors a scaffolding made up of a set of superimposed stages and nested, this frame comprising a vertical upright provided with nesting means allowing it to nest on the corresponding vertical amount of an underlying frame.
- This frame has bracing linking the amount to a vertical hand provided with a locking means, this hand able to engage laterally, by pivoting around amount, and be locked, as soon as it stops, on the vertical upright of a similar neighboring frame of said stage.
- bracing here is triangular, which requires at the lower and upper ends a additional frame.
- the present invention aims to obtain simplification of such a structure, and for this purpose, a framework for floors of scaffolding of the type mentioned at the beginning is characterized in that said connecting bracing of said amount to said vertical hand has two beams horizontal with only slightly less spacing at the height of said vertical hand, so that between them, in the vicinity of said amount, the blocking of the vertical hand of the frame next to the floor.
- each stage of the scaffolding can be consisting of three, four, five similar vertical frames, each having a post at one end and a hand at the opposite end, the hand of each frame being engaged and locked on the amount of the frame next to the same floor, and the scaffolding can then be constituted by a number of such superimposed identical stages and nested.
- braces By the expression “similar vertical frames”, it must hear vertical frames whose extreme parts are identical but whose braces may have all the same length or several different lengths. When the braces are all the same length, the frames will be absolutely identical, and all floors of the scaffolding can then be square. With two lengths different bracing for example we can oppose two to two frames of the same length on two opposite sides of the floor, and two length frames different on the other two opposite sides, which will get rectangular floors of everything module.
- the vertical upright being tubular
- said vertical hand consists of a shaped sheet in a gutter with a substantially semi-circular cross section, opening towards the outside of the floor and in a direction substantially perpendicular to the plane of the frame.
- This provision offers the possibility of mount all the frames successively from inside the scaffolding being erected, the worker having the feet on a floor placed on the lower frames, which ensures its safety.
- said locking means consists of a latch pivotally mounted on an edge of said hand vertical and suitable for being locked in position substantially horizontal in front of an upright housed in said hand.
- each frame for floor scaffolding has been designated by reference 1.
- This frame is consisting of a tubular upright 2 connected by a brace 3 to one hand shaped section gutter substantially semicircular 4.
- Bracing is consisting of two bars 5 connected by a central crosspiece 6 and welded at one end to the upright 2 and at the other end to a bar 7 on which the hand is fixed 4.
- the upright 2 of the following frame can be locked in the hand 4 of the previous frame by a latch 8 as better visible in Figures 3 and 4.
- This latch consists of a plate mounted on the side 7 of the hand 4 by a pivot axis 9; a heel 10 of this plate, coming to abut on the edge of flank 7, can keep it in a horizontal position, which prevents post 2 from escaping from hand 4. To unlocking, just lift the latch 8 thanks to plate 11.
- the base stage When the base stage is thus formed and locked, it fits the amount 2 of a fifth frame 1 on the amount 2 of one of the frames of the base floor, and one proceeds to the mounting and locking of the second stage in the same way as for the first, the working floors P 1 , P 2, etc. are mounted, and so on until reaching the desired scaffolding height.
- FIG. 6 there are shown cylinders to screw to adjust the plumb of the scaffolding, and 13, at the top of the upper 2 uprights, other screw jacks for adjusting the level of forks or the like 14 of reception of planks, for the constitution of a floor formwork, for example.
- Such scaffolding can have all other uses possible in building technology (scaffolding service, shoring, etc.).
- the frames form a security bodyguard compliant with regulations French.
