[0001] The present invention relates to a height supplement for portals and frameworks of
facade scaffolding which has characteristics of novelty and inventive step compared
with the prior art.
[0002] As is known, in facade scaffolding, portals are provided, intended to be connected
to other structural members and intended to bear on the ground or on other areas of
the scaffolding, making it possible as a whole to produce the facade scaffolding.
In the particular case of portals supported on the ground, the problem often arises
of sloping of the ground, which requires the portal to have sides of different heights.
Although it is possible to adjust the height of one of the sides of the portal differently
from that of the other side by means of adjustable-height feet with the upright legs
known at present, which are used in the aforesaid portals, the possibility of height
adjustment is reduced, so that in many cases there are significant difficulties in
adapting to a specific change in level of the ground.
[0003] The present invention is intended to remedy the aforesaid drawback, by disclosing
a portal height supplement device for facade scaffolding which makes it possible to
achieve new ranges of height values of the upright legs of the conventional portals
known at present. For this purpose, the supplement of the present invention has a
straight tubular body with screw-adjustable foot, such as is known in this field,
and further has over its height a minimum of two supports with centring which are
intended to receive the tubular members of the upright legs of the portals, so that
by using the desired support, it is possible to obtain an extension in height on the
arm of the portal, which can then still be adjusted by the screw-adjustable foot.
The tubular body of the supplement device will have clamps in the shape of an adjustable
articulated flange or other type for securing it to the upright leg member of the
portal. By means of this arrangement, the desired extension of one or both legs of
the portal is effected in a rapid and simple manner, such that there is no significant
reduction in the mechanical characteristics of the portal, no increase in the transverse
dimensions thereof is required, and, moreover, rapid and simplified positioning is
made possible.
[0004] For greater understanding, drawings corresponding to a preferred embodiment of the
present invention are appended by way of non-limiting example.
[0005] Figure 1 shows a side view in elevation of a height supplement for portals of facade
scaffolding according to the present invention.
[0006] Figure 2 shows a plan view of the member in Figure 1,
[0007] Figures 3 and 4 show perspective views of a member according to the invention and
of the same member immediately after receiving the arm or upright leg corresponding
to a portal which it is desired to extend.
[0008] Figure 5 shows a front view in elevation of a portal equipped with two height supplement
devices according to the present invention, located on a flat surface.
[0009] Figure 6 is a figure similar to Figure 5 in which the two legs of the portal bear
at a different height.
[0010] As can be observed in the drawings, the height supplement for portals and frameworks
of the present invention essentially comprises a straight tubular member 1 equipped
at different points over its longitudinal extent with a minimum of two supports 2
and 3, each carrying a rod, respectively 4 and 5, parallel to the tubular element
1 and capable of receiving, fitted onto it, an upright leg 6, Figure 4 and onwards,
of a portal 7, one or both sides of which it is desired to extend.
[0011] By being able to select between one or other of the two or more auxiliary supports,
different effective extensions of the upright legs of the portal or framework are
obtained, which may receive at the bottom the feet 8 adjustable by means of screw
thread and wing nut 9 of a type known in this art.
[0012] On its upper part, the height supplement member 1 will have two securing devices
10 and 11, for example of the clamp type or others, which can also be seen in Figure
2 and which will allow the supplement to be secured to the upright leg 6 of the portal
(Figures 5 and 6).
[0013] In this way great strength is obtained in the placing of the height supplement, as
well as significant simplicity of handling.
[0014] When desired, if the floor 12 has areas of different height such as those indicated
by the numbers 13 and 14 in Figure 6 for the support of the upright legs 15 and 16
of a portal 17, the invention will make it possible to adjust to a different height
one or both of the legs in the event that it is desired to increase the height of
the portal in a simple and rapid manner.
1. A height supplement for portals and frameworks of facade scaffolding, characterised in that it comprises a straight tubular body provided at different points over its longitudinal
extent with supports equipped with rods parallel to said tubular body of the supplement,
each intended to receive the end of an upright leg of a portal which it is desired
to extend in height, said tubular body of the height supplement further having detachable
members for securing to the upright legs of the portal which it is desired to extend,
and having at the bottom a seating to receive the adjustable-height feet of the supports
and portals for scaffolding.
2. A height supplement for portals and frameworks of facade scaffolding, according to
claim 1, characterised in that the devices for securing the height supplement to the upright legs of the portals
to be extended consist of adjustable articulated clamps.
