One or several mechanisms act on the telescopically coupled support components also to make them pass from a work static state to a dynamic state on twirling wheels.
Description
MOVABLE MODULAR SCAFFOLD SYSTEM FOR BUILDING WORKS AND METHOD TO FORM IT.
BACKGRIUING AND FIELD OF THE INVENTION
The present invention concerns movable, modular scaffold systems for building works, comprising at least one platform adjustable in length, height and width, said scaffold system being integrally displaceable without de-mounting and re-mounting of its sub-systems.
In a preferred embodiment of the invention the system comprises at least 5 sub-systems, a sixth sub-system being optional.
PRIOR ART
Presently the building activity, in particular the residential building enterprise knows a rather paradoxical situation in the sense that, especially in the big towns the buildings have taken a quite intensive characteristic, f.i. in form of skyscrapers with height from 30-40 up to 600 meters. In this frame, scaffoldings for the erection of big height buildings have been currently developed, said buildings being tamponed with the aid of large panels pre-fabricated outside erecting yard.
The scaffolding for such big buildings is of the industrial type and comprises vertical supports (mainly hollow tubes), which can be interconnected by means of horizontal bars.
Plates which extend on a horizontal plane can be hooked into the bars to create an accessible working surface. Some prior Art documents are mentioned hereinafter to give an idea on said situation.
Spanish Patent Publication ES 2307797 is concerned with a demountable, multi-stage scaffolding comprising walk-on floor levels supported by vertical struts with railings fitted on through an adaptor attachable to rosette supports above floor at distance not restricted by the spacing between rosettes.
DE 102004060653 describes a framework having a guide system connected to a supporting system.
In the PCT Patent Application Published as WO2008/000654 a lifting platform is described which comprises a base (that can be set up on a ground and converted into a console), and a platform which can be lifted in relation to said base. The lifting system consists of two lateral columns.
EP 1398432 is concerned with formwork based on a support consisting of four tubular elements, and of an adaptor for said formwork.
Summarizing the panorama of the construction scaffolds can therefore be divided in a field of big buildings in which are needed big scaffoldings and a current field of small, middle buildings; in the first field of big scaffoldings there is an intensive search work to develop continuously improved systems, whereas in the small and middle building field the search of advantageous lifting platforms is rather limited. Indeed the minor costs of small-middle buildings do not allow the search and commercial expansion of sophisticated scaffoldings.
There is also the other aspect that in the second field of the small-middle building there is a very high number of small contractors which have their own traditional building techniques wherein use is made of conventional scaffoldings.
Accordingly, at the best knowledge of the Applicant, it seems absent on the market an appropriate scaffold system which is modular, has a platform adjustable in the three directions X, Y, Z, is easily hand traversed without de-mountings and re-mountings, the system itself is safe, has not high costs, allows a sensitive reduction of the working times, and avoids loss or breaks of components.
SUMMARY OF THE INVENTION
First object of the present invention is to provide a compact, easy to set up, integrally displaceable, safe and highly performant scaffold system.
A second object is to provide a method to easily set-up, to adjust in height and length the platform, and to integrally displace said system.
The main features of the scaffold system according to the invention are recited in the claims, at the end of this description, said system substantially consisting of at least five sub-systems and optionally of a sixth sub-system.

- figure 1 is a block diagram showing the components (sub-systems) of the system according to the invention, and their inter-related functions;
- figures 2 and 3 are exploded perspective views from the bottom, of an advantageous and therefore preferred embodiment of the invention, figure 3 being a view on the scaffold of fig. 2, turned of 90°;

- figure 5 is a front view of the system with an extended platform supported by end poles; and
- figures 6 and 7 are a top view respectively a bottom view of figures 2, 3 and 5. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
In the block scheme of fig. 1, the efficacious system according to the invention which is typically movable as an integral body, without the need of demountings and re-mountings, highly safe and with a platform controllable in height, length and width, comprises several sub-systems. In particular the following five ones:
- Sl - a first sub-system involving at least one work platform which is extensible in width and length and adjustable in height;
- S2 - sub-system of first interface comprising means to couple Sl and S3;
- S3 - sub-system of upper adjustable supporting structure;
- S4 - sub-system of second interface for the adjustable coupling of S3 and S5; and
- S5 - sub-system of lower supporting structure to determine the work stationary conditions, and the movement non-stationary conditions.
As it can be seem from the preferred embodiment shown in the figures from 2 to 6, in particular from the exploded, perspective views (front view in fig. 2 and lateral view in fig. 3) a platform PIA comprises a central principal element or footboard 1 which is advantageously extensible with the aid of at least two lateral and overturnable elements 2 (on the right hand) and 3 (on the left hand) which can be generally assembled on site and overturned with the aid of coupling means of temporally constraint, f.i. with n hinges 4] - 4n, n bolts 5 - 5n and m rods 6j-6m. The platform forming elements 1, 2 and 3 comprise a main frame Tl and several extension frames T2, T3 obtained with the aid of pairs of longitudinal bars or rods 7- T stiffened by transversal bars S1 - 8n. The coupling of elements 1, 2 and 3 can also be of the male-female types, or of the clip type even if, obviously, other coupling elements ( preferably as available on the market) can be used. In other words, the structures of the three (or more) extensible platform elements and of the related association and overturning means 4, 5 and 6 can also be different from those shown in the drawings, on condition that they guarantee always an extremely strong platform both in the form of a mono-element platform (Tl) or in the form of multi-element platform (Tl, T2, T3). Also their articulation by hinges 4D, 4S must be safe and reliable.
According to a first feature of the invention, two pairs of overturned "glasses" 10-10' project downwards from the lower (or proximal) faces of the longitudinal bars of the central frame
Tl, the number of said "glasses" 10-10' is to be equal to the number of the uprights 11-11', 12-12' of the support sub-system S3.
Typically the proximal opening or mouth 9 of said glasses B-B', Bl-Bl' is to be slightly wider than those of the heads or tops 15 of said uprights 11-11', 12-12', of the support subsystem S3 so to facilitate the insertion of said mouths (associated to platform central element 1) within the terminal ends 15 of said uprights which are provided of holes 16 for the passage of bolts and/or stiffeners.
As it will be better seen in the following, a certain stiffening between these elements is needed as the height of the uprights 11-11 ', 12-12' is adjusted for instance by jackscrews Ml (motorized or not), winches or similar devices, which push upwards the shafts or pistons 18 to have each time the platform at a work optimal height according to the building structure under construction.
According to an other aspect of the invention the inner longitudinal bars 7, 7D and 7S of frames Tl, T2, T3 are provided with the means for the coupling, through said hinges, bolts and rods and the like, with the extension elements 2 and 3 so to bring about also a good inter- system modularity, i.e. the union (with form constraint and, additionally, with stiffening of said coupling means like hinges, bolts, bars, rods) of one or more integral system SI, one SID at the right side of the platform 2 and one SIS to the left side of element 3. In other words the integral (mono-body) SI of figures 2, 3 and 5 is conceived in such a way to get united to one or more other similar integral system SI' identical to SID or SIS, in order to form multiple combined super-system to cover f.i. any building extension. Those unions are brought about with the aid of sub-system 6 which is a mover (f.i elevator, skiphoist) to hoist and/or push said additional integral systems Sl ' (practically a copy of SI). This chain of single integrated systems (SID, SI, SIS or SF, SI, SI") according to the invention is not shown as it is per se strongly intuitive. By returning to the single system of
figures 2 and 3, the four superior uprights 11-11', 12-12' and the inferior uprights 13-13', 14- 14' of sub-system S3 are reinforced (stiffened) by beans (cross-bars) pairs 21-22, 41-42, 43- 44; preferably the two beans of each pair are perpendicular to each other. Said reinforcements by crossed couples assure the possibility to charge the platform with the maximum charges of workers and materials as well as to place the system in static work (resting on the plates 50 at the lower end of lower uprights 13-13', 14-14') and to make the passage of the whole integral system from this static position to the movement dynamic one obtained by disconnecting (with the aid of a second vertical movement organ like jackscrew M2) the system from plates 50 (resting, on their turn, on possible ground plates) and by inserting the twirling (pirouetting) wheels RP which allow the planar displacement of the whole integrated system according to the invention. Thanks to the wheels said displacement can take place even by a manually pushing of the people working in the building yard. In said figures Ll and L2 indicate the lever of the hydraulic jacks Ml and M2, whereas 64- 64' indicate the pistons (shafts or bars) to hoist S5 and to rotate the twirling (pirouetting) wheels. The telescopic run of the glasses 10-10' on the superior uprights 11-11', 12-12' to finely adjust the platform height is generally rather short and at most equal to the depth of same glasses. On the contrary the telescopic stroke of the inferior uprights 11-11', 12-12' (less wide) is longer as it is depending on the hoisting from ground and insertion of the wheels RP.
The poles PUD-PUD', PUS-PUS' which bear the outer or intermediate ends of the extension elements 2 and 3 of the platform PIA in extended configuration, are provided with ribs to insert the bolts 6', with bearing plates to ground 51 and with flywheels V-V to adjust the extension, i.e. to adapt them to the different platform height over the ground. Similarly to the uprights 11-11', 12-12' and 14-14', said poles are also constituted of two telescopically coupled bodies 80-80', 81-81' .
As shown in fig. 4, said two pairs poles PUD-PUD', PUS-PUS' of figures 2 and 3 can be substituted by adjustable tie rods TR. Said tie rods can advantageously be pre-fixed, even before hand, to the knots of frames Tl, T2, T3 and later request the anchorage on site through hooks 89, to the upper uprights 11-11', 12-12'. The adjustment is made with the aid of elements 91 like spring or compressed fluid shock absorbers, activated by levers or flywheels
92.
Figure 6 is a plan view of the extendable platform formed of three assembled elements 1, 2 and 3. Figure 7 is a plan view (from below) of the wheel carrier device RP and plates 50, fixed to the inferior transverses 54-54'.
In these last figures have been used the same references of figures 2-5 whereby it seems not necessary to make a redundant description thereof. In figure 5 the hinges 4D and 4 S bridging the two frames T2 and T3 indicate that the two platform extending pieces 2 and 3 can overturn and take a position along uprights 13 and 14'.
The preferred method to embody the system according to the present invention comprises at least the steps wherein:
- the platform width and/or length are extended by applying to its central element (1) at least one extension element (2, 3) using fixation means pre-disposed on such elements which are already provided with connection means to at least an other platform (PIA') of a second SID and/or third integral SIS system thanks to their modularity;
- the uprights of the two supporting sub-systems (S3) and (S5) are telescopically combined by inserting those of (S3) within those of (S5);
- the glass mouths (B-B') protruding from the lower face of the platform central element (1) are set over the upper ends of the sub-system (S3) uprights preferably already assembled with the (S5) wider uprights;
- the platform height is adjusted according to the under- work building height by acting on a mechanism preferably a jackscrew (M) associated to (S3);
- the (Sl), (S2), (S3) combined ensemble is placed on static plates associated at the feet of the sub-system (S5); the displacement movement of the whole system to an other work zone is carried out by lifting the integral combined body (Sl + S3 + S5) from said immovable plates to the twirling wheel mechanism; and
- the whole integral system is lifted by a lifting apparatus in particular by the subsystem (S6) elevator in a new work place different from the ended initial work place.
For scruple of illustrative clarity and simplicity, the invention has been described with particular reference to the embodiments shown in the accompanying drawings; said invention cannot however be considered as restricted to said embodiments but it is to be intended as comprising all changes, substitutions, additions and the like which if being in the hand reach of the field mean technical expert, fall naturally within the scope of the following claims.

5) System according to claims 1 and 4, characterized in that said uprights of sub-system (S3) are hollow and, besides their upper penetration in said downwards projecting mouths of the platform central element (1), their lower opened ends (15') penetrate telescopically also into the upper end openings (15") of the lower (S5) forming uprights (13-13', 14-14') and have transversal cross-section (15") higher than that of the lower ends (15') of the superior uprights of (S3).
6) System according to claim 1, characterized in that the platform extending quadrangular, rectangular, trapezoidal elements (2 and 3), are provided at their four apex with anchorage means (6") to block the free higher ends (16) of poles (PUS-PUS', PUD- PUD') which are also telescopic and extend down to the ground from said apex.
7) System according to claim 1, wherein adjustable tie bars (TR) are anchored between the apex of the platform extending lateral elements and the outer surface of the (S3) superior uprights (fig. 4).
8) System according to claim 1, characterized in that hollow means to couple (S3) and (S5) have an aperture double gradient whereby they have openings minor than both those of the overturned glasses of (S2), and those of the upper ends of (S5) uprights.
9) System according to claim 8, characterized in that said (S3) uprights (H-H', 12-12') make short up-down runs within said (S2) glasses under the action of a lifting first organ preferably a jackscrews; in order to finely adjust the platform height over that of the building work.
10) System according to claim 1, characterized in that the (S5) upright lower ends are provided as well with immovable plates whereupon said uprights rest during the work
stationary conditions, as with twirling wheel mechanisms on which the whole integral system is transferred for the movement step, the transfer from the immovable plates to said movable pirouette wheels being carried out under the action of a second lifting organ preferably a second jackscrew which makes the wider uprights of (S5) to telescopically slide on the less wide uprights of (S3). 11) Method to embody the system according to the above claims, wherein:
- the platform width and/or length are extended by applying to its central element (1) at least one extension element (2, 3) using fixation means pre-disposed on such elements which are already provided with connection means to at least an other platform (PIA') of a second and/or third integral (SF) system thanks to their modularity;
- the uprights of the two supporting sub-systems (S3) and (S5) are telescopically combined by inserting those of (S3) within those of (S5);
- the glass mouths (B-B') protruding from the lower face of the platform central element (1) are set over the upper ends of the sub-system (S3) upright preferably already assembled with the (S5) wider uprights;
- the platform height is adjusted according to the under- work building height by acting on a mechanism preferably a jackscrew (M) associated to (S3);
- the (Sl), (S2), (S3) combined ensemble is placed on static plates associated at the feet of the sub-system (S5);
- the displacement movement of the whole system to an other work zone is carried out by lifting the integral combined body (Sl + S3 + S5) from said immovable plates to the twirling wheel mechanism; and
- the whole integral system is lifted by a lifting apparatus in particular by the subsystem (S6) elevator in a new work place different from the ended initial work place.
