Definitions
- the present invention relates to a falling head support device for supporting beams of formworks for floors.
- the aim of the present invention is to provide a falling head support device for supporting beams of formworks for floors that is structurally simple, achieving savings in their production.
- an object of the present invention is to provide a falling head support device for supporting beams of formworks for floors that is particularly resistant to the loads applied thereto.
- Another object of the present invention is to provide a falling head support device for supporting beams of formworks for floors provided with the safety systems required by the standards applicable to the field.
- Another object of the present invention is to provide a falling head support device for supporting beams of formworks for floors that is easy to use.
- Another object of the present invention is to provide a falling head support device for supporting beams of formworks for floors that can be manufactured with known systems and technologies.
- a falling head support device for supporting beams of formworks for floors, comprising: - an upright, which can be fixed at its end to a supporting strut that rests on the ground,
- a supporting head for at least one beam for supporting a formwork for floors, which is coupled so that it can slide along said upright, said supporting head being provided with safety abutment elements for the end of the supporting beam during the setup and removal of the formwork of said supporting beam,
- said supporting head comprises: - two plates, which are arranged mirror-symmetrically so that they are laterally adjacent to opposite sides of said upright and are suitable to delimit laterally a region for accommodating the end of the at least one supporting beam,
- each recess being provided on a respective one of said plates, a single prism-shaped element being welded to the bottom of each recess, being wider than the thickness of the plate and being suitable to support the supporting portion of the supporting beam, - a transverse element for connecting said two plates, which is suitable to support temporarily an inclined lower portion of the supporting beam during the setup and removal of the formwork of said beam.
- Figure 1 is a perspective view of a device according to the invention, with a supporting beam for formwork of floors associated therewith;
- Figure 2 is a partially sectional side view of the device of Figure 1 ;
- Figure 3 is at top view of the device of Figure 2;
- Figure 4 is a partially sectional front view of the device of Figure 2, with a supporting beam for formwork of floors associated therewith.
- a falling head support device for supporting beams of formworks for floors according to the invention is generally designated by the reference numeral 10.
- the support device 10 comprises a tubular upright 11, which has a square cross-section and, at the upper end, a T-shaped portion 12.
- a flat bracket 13 is provided at the lower end of the upright 11, and a shank 14 protrudes downward from said bracket so as to be substantially aligned with the upright 12; the shank is designed to be inserted in a corresponding tubular supporting strut that rests on the ground (not shown in the figures) and is provided with a complementary plate to which the flat bracket 13 is locked by means of bolts.
- the supporting head 15 comprises a base plate 17, to which two plates 18 are welded edgeways and are arranged in a mirror-symmetrical fashion so that they are laterally adjacent to opposite sides of the upright 11 and are suitable to delimit laterally a region 19 for accommodating the end of the supporting beam 16.
- each plate 18 is symmetrical with respect to a vertical centerline axis, and as a pair the plates 18 consequently form two regions 19 for accommodating the ends of contiguous and aligned supporting beams 16.
- the base plate 17 is provided centrally with a through hole 20 in order to allow its sliding along the upright 11 ; in particular, sliding is allowed for a single initial portion Ha of the upright 11, which is comprised between the flat bracket 13 and two stroke limiters 21, which are arranged on opposite sides of the upright 11 in an intermediate position thereof.
- Means 22 for reversibly locking said supporting head in a preset position defined along the upright 1 1 are associated with the supporting head 15.
- Two recesses 23, suitable for resting the end of respective supporting beams 16, are provided on each plate and are arranged symmetrically with respect to the vertical centerline axis.
- the recesses 23 of respective mirror-symmetrically matching plates 18 are useful for supporting the end of a respective supporting beam 16, as described hereinafter.
- the recesses 23 have a substantially V-shaped profile and guide the insertion and containment of a supporting portion 24 of the corresponding supporting beam 16.
- the surface for supporting the supporting portion 24 of the supporting beam 16 is formed by the bottom 25 of the recess 23 of each plate 18 and by the lateral edge 26 of a respective plate-like element 27, which is arranged rigidly laterally adjacent to the plate 18, so that the lateral edge 26 is substantially at the same height as the bottom of the recess 23.
- the supporting portion 24 is constituted by the lower portion of an inverted T-shaped body, which is welded at its end to the supporting beam 16.
- a single plate-like element 27 is associated with each plate 18 and is longer than the distance between the recesses 23 of a same plate.
- a lower portion 16a of the beam 16 may also rest on the lateral edges 26 of the plate-like elements 27 (as shown in Figure 4) discharging part of the weight from the welds of the inverted T-shaped body (welded at its end to the beam 16) that forms the supporting portion 24.
- each plate-like element 27 is suitable to abut, with its lateral edge 26, against a respective stroke limiter 21.
- each plate-like element 27 forms, together with its corresponding element, a pair of containment and guiding elements for the head 15 on the upright 1 1.
- the supporting head 15 is provided with safety abutment elements 29 for the end of the supporting beam 16 during the setup and removal of the formwork of said beam.
- the safety abutment elements 29 are constituted by hook-shaped portions 30, which protrude, as a continuation of the upper portions of the recesses 23, outward and toward the upper region of the plates 18.
- the concave region of the hook-shaped portions 30 is substantially directed toward the upright 1 1.
- the hook-shaped portions 30 prevent the supporting beam 16, once it is disengaged from one of the two heads that support it at its end, from disengaging accidentally from the remaining one, falling disastrously onto the workers below.
- the inverted T-shaped body which forms the supporting portion 24 of the end of the beam 16, that engages by way of the laterally protruding parts the hook-shaped portions 30.
- the supporting head 15 is provided with a transverse element
- the transverse element 31 for connecting the two plates 18, which is suitable for temporarily supporting an inclined lower portion 32 of the supporting beam 16 during the setup and removal of the formwork of the beam, thus facilitating these steps.
- the transverse element 31 is constituted by a cylindrical pin, which is welded at the end to the two plates 18.
- first portion (not shown in the figures, since it is superimposed on other components), which is substantially equal to the width of the initial portion 11a of the upright 11, and a second portion 34, which is larger than the dimensions in plan view of the cross-section of the initial portion 11a.
- the upright has, on opposite sides, two wings 35, on the upper ends of which the first portion of the frame 33 rests so that it can slide.
- the base plate 17 of the supporting head 15 rests on the frame 33 thus arranged; said head, therefore, cannot fall, since it is supported by the frame.
- the edge of the frame 33 at the first portion is inclined upward toward the second portion 34.
- the two guiding plates 28 for sliding on the upright 11 guide the head 15 along the upright 11, in practice being arranged laterally adjacent to the wings 35 (and an extension 35a of the wings 35 that is separated from them in order to allow the support of the frame 33).
- a falling head support device for supporting beams of formworks for floors has in fact been provided which is structurally simple and achieves savings in its production.
- the number of components of the device is in fact reduced with respect to commercially known solutions, and the method of assembly is also easier, reducing the number of welds to be provided.
- the structure of the device has been lightened and simplified, its load bearing strength is optimum.
