Ways to carry out the invention

With reference to the figures, a decreasing load bearing device for floor formwork beams according to the invention is generally designated by reference number 10.

The support device 10 comprises a tubular upright 11 having a square cross section and, at the upper end, a T-shaped portion 12.

A flat clamp 13 is provided at the lower end of the stud 11, and a rod 14 protrudes downward from said clamp to be substantially aligned with the stud 12; The rod is designed to be inserted into a corresponding tubular support bar that rests on the floor (not shown in the 20 figures) and is provided with a complementary plate to which the flat clamp 13 is closed by bolts.

A support head 15, in this exemplary embodiment for two support beams of a floor formwork, is slidably coupled to the post 11; A single beam, designated by reference number 16, is shown in Figures 1 and 4. 25

The support head 15 comprises a base plate 17, to which two plates 18 are welded sideways and are arranged in a mirror-symmetrical manner so that they are laterally adjacent to opposite sides of the stud 11 and are suitable for laterally delimiting a region 19 to accommodate the end of the support beam 16.

In this exemplary embodiment, each plate 18 is symmetrical with respect to a vertical axis 30 of the central line, and as a pair the plates 18 consequently form two regions 19 to accommodate the ends of adjacent and aligned support beams 16.

The base plate 17 is centrally provided with a through hole 20 in order to allow its sliding along the upright 11; in particular, the slip is

allowed for a single initial portion 11a of the upright 11 which is comprised between the flat clamp 13 and two travel limiters 21 that are arranged on opposite sides of the upright 11 in an intermediate position of its own.

Means 22 for reversibly closing said support head in a predetermined position defined along the upright 11, described below, are associated with the support head 15.

Two holes 23, suitable for resting the end of respective support beams 16, are provided on each plate and are arranged symmetrically with respect to the vertical centerline axis.

The holes 23 of respective matching mirror-symmetric plates 18 are useful for supporting the end of a respective support beam 16, as described below.

In particular, the gaps 23 have a substantially V-shaped profile and guide the insertion and containment of a support portion 24 of the corresponding support beam 16. 15

In particular, the surface for supporting the support portion 24 of the support beam 16 is formed by the bottom 25 of the recess 23 of each plate 18 and by the side edge 26 of a respective plate-like element 27 which is rigidly arranged and laterally adjacent to the plate 18 so that the lateral edge 16 is substantially at the same height as the bottom of the hole 23. 20

The support portion 24 is constituted by the lower portion of an inverted T-shaped body that is welded at its end to the support beam 16.

A single plate-like element 27 is associated with each plate 18 and is longer than the distance between the gaps 23 of the same plate.

In this way, a lower portion 16a of the beam 16 can also rest on the side edges 26 of the plate-like elements 27 (as shown in Figure 4) by discharging part of the weight of the welds of the shaped body of inverted T (welded at its end to beam 16) forming the support portion 24.

In addition, each plate-like element 27 is suitable for resting, with its side edge 26, against a respective travel limiter 21. 30

In addition, each plate-like element 27 forms, together with its corresponding element, a pair of containment and guide elements for the head 15 in the post 11.

On opposite sides of the passage hole 20, transversely with respect to the plates 18, there are two guide plates 28 for sliding on the post 11, which are suitable for forming

in practice a pair of elements to contain and guide the head 15 that is perpendicular to the pair formed by the plate-like elements 27.

The support head 15 is provided with safety support elements 29 for the end of the support beam 16 during the assembly and disassembly of the formwork of said beam. 5

In particular, the safety support elements 29 are constituted by hook-shaped portions 30 that protrude as a continuation of the upper portions of the recesses 23, towards the outside and towards the upper region of the plates 18.

The concave region of the hook-shaped portions 30 is directed substantially towards the stud 11.

The hook-shaped portions 30 prevent the support beam 16, once it has been disengaged from one of the two heads supporting it at its end, accidentally disengaging from the remaining one, falling disastrously on the workers who are below. fifteen

In particular, it is the inverted T-shaped body that forms the support portion 24 of the end of the beam 16, which engages by means of the laterally projecting portions of the hook-shaped portions 30.

In addition, the support head 15 is provided with a transverse element 31 for connecting the two plates 18, which is suitable for temporarily supporting an inclined lower portion 20 of the support beam 16 during the assembly and disassembly of the beam formwork, thus facilitating these steps.

The cross member 31 is constituted by a cylindrical pin that is welded at the end to the two plates 18.

In summary, the means 22 for reversibly closing the support head 15 25 comprise a frame 33, which is centrally provided with a passage cavity that is substantially formed to form two separate portions: a first portion (not shown in the figures since is superimposed on other components), which is substantially equal to the width of the initial portion 11a of the post 11, and a second portion 34 that is larger than the plan view dimensions of the cross section 30 of the initial portion 11a.

In this initial portion 11a, the upright has two wings 35 on opposite sides, at whose upper ends the first portion of the frame 33 rests so that it can slide.

The base plate 17 of the support head 15 rests in the frame 33 thus arranged; said head therefore cannot fall, since it is supported by the frame.

Advantageously, the edge of the frame 33 in the first portion is inclined upward towards the second portion 34. 5

By pushing the frame 33 on the side corresponding to the second portion 34 towards the upright 11, said frame slides at the upper ends 36 of the two wings 35 until the second portion 34 is located therein: since it cannot be supported by the wings 35 because the second portion 34 is wider than the post 11 with the wings 35, said frame falls downwards to reach the clamp 13, together with the support head 15.

It should be noted that the two guide plates 28 for sliding on the stud 11 guide the head 15 along the stud 11, in practice being arranged laterally adjacent to the wings 35 (and an extension 35a of the wings 35 which is separated from them in order to allow frame support 33). fifteen

In practice it has been discovered that the invention described in this way achieves the objective and the intended objects.

A declining load bearing device for supporting floor formwork beams has in fact been provided, which is structurally simple and achieves savings in its production. twenty

The number of components of the device has in fact been reduced compared to commercially known solutions, and the mounting method is also easier, reducing the number of welds to be provided.

Although the structure of the device has been lightened and simplified, its load capacity is optimal. 25

In practice, the materials used, provided they are compatible with the specific use, as well as the dimensions, can be any according to the requirements and the state of the art.

Where the technical elements mentioned in any claim are followed by reference signs, those reference signs have been included with the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs have no limiting effect on the interpretation of each element identified by example by such reference signs.
