[0001] This invention is related to a casting mould device which is suited for casting concrete
and similar, especially for making base plates, columns, column footings, walls and
similar, and also for recesses in walls and similar, e.g. for windows, doors and similar,
and for stop ends for arches and structural floors, stop ends in lift wells and similar.
[0002] The device is especially suited for low moulds with a height of up to 1.5 m, especially
up to 1.2 to 1.0 m or less, e.g. up to 0.8 or 0.6 m or in some cases up to 0.4 m,
and usually with a height of at least 0.15 m or 0.25 m.
[0003] The casting mould device according to this invention comprises according to an embodiment
one or more support beams, also denoted horizontal beams, which are suited for carrying
or supporting shuttering panels or parts of shuttering panels or similar casting mould
surface forming elements and which preferably are arranged essentially parallel to
said mould surfaces, and transverse supports, also denoted vertical supports, for
said support or horizontal beams. Said transverse supports (vertical supports) are
preferably arranged essentially perpendicular to the support beam(s) and the mould
surface resp. and are intended to transfer the mould pressure, e.g. the pressure of
the cast concrete, to a base or anvil, such as the ground or a wall etc. Said transverse
supports (vertical supports) have preferably essentially triangular shape comprising
a post, which is normally arranged parallel to the mould surface forming element,
such as a shuttering panel or similar, or optionally carries directly the element
forming the mould surface. Said post is usually arranged with its longitudinal direction
extending essentially vertically, but may also be arranged in a direction which deviates
e.g. up to 45 degrees, preferably up to 30 degrees or up to 15 degrees from the horizontal
plane, e.g. for supporting a mould bottom surface.
[0004] The post is connected to a base part, also denoted bottom part, of said transverse
support, to which the mould pressure is transferred from the post and from which the
mould pressure is transferred to a base, preferably the ground or optionally a wall
or another force supporting body. The mould pressure is preferably transferred to
said base part with a brace (strut) extending from said post to said base part, preferably
from the upper part of the post to the section or end of the base part which is remote
from the post. More than one brace can be used, e.g. in case the post is very long
and a high casting mould exerting a high casting pressure is to be supported, e.g.
a height above 1 m and preferably above 1.5 or 2 m. The base part, as well as the
post, preferably has elongated shape with a length which is several times its breadth.
The base part (bottom part) can be secured to the base in various ways, e.g. by being
provided with holes or openings or other means for fastening with e.g. bolts, bars,
nails, etc.
[0005] The post and the base part are fixedly or releasably and/or pivotably connected to
each other at one end of said elements, preferably with a bolt joint or a similar
means which makes possible a rotating motion of said parts in relation to each other
in a plane. This is suitably achieved by bonding said parts together with a bolt or
a similar joint which is pivotable in one plane, whereby a suitable angle between
the post and the base part can be achieved by joining one end or both ends of said
brace pivotably or displacably to the post and base part resp. The angle between the
post and the base part may e.g. be varied with up to 60 degrees, preferably up to
45 degrees or up to 30 degrees or 15 degrees from a straight angle, in one direction
or in both directions.
[0006] It is usually suitable to use at least two support beams (horizontal beams) connected
to at least two transverse supports (vertical supports), but a larger number of beams
and supports may, of course, be used when required.
[0007] The support beams are preferably straight for supporting flat surfaces, but also
curved beams can be used for supporting curved mould surfaces.
[0008] A suitable profile of the support beams (horizontal beams) is a Z-profile which permits
uncomplicated fastening to the posts and uncomplicated fastening of the shuttering
panels or other mould surface forming elements to the support beams.
[0009] The expression "Z-profile" may also comprise other profiles in which the shape of
the Z-profile is comprised, e.g.
H-profile, h-profile, etc. As an alternative it is also possible to use other beam
profiles which permit fastening to the transverse supports and fastening of shuttering
panels or other mould surface forming elements, such as U-beams, preferably with a
more narrow flange facing and fastened to the transverse supports and a broader flange
facing a shuttering panel or similar means fastened to said flange.
[0010] The fastening means for joining the support beams to the transverse supports may
for Z-beams and similar form a vertical gap adjacent the post into which a flange
of the beam can be pushed down. The fastening means may be fixedly joined to the post
or stepwise or continuously (stepless) displacable in the longitudinal direction thereof
and may be arranged for being locked in a desired position, e.g. be arranged for being
fastened or snapped into openings arranged at various levels along the post. Preferably
the fastening means for the support beams are arranged for being braced to the post
with bolt joints, e.g. with fly nuts and with the bolt displacable in grooves extending
in the longitudinal direction of the post, e.g. grooves which extend through the surface
of the post facing the mould surface.
1. A transverse support (3) suited for use for supporting a
casting mould device for casting concrete, e.g. for base plates, walls, column, recesses
and similar, comprising a number of transverse supports (3), which transverse support
has substantially triangular shape with a post (4) which is connected to a base part
(5) with a joint pivotable in one plane, and a brace part (6) extending between the
post and the base part, the posts of the transverse support (3) being suited for supporting
a mould shuttering (2) with a height of 1,5 m or less with the aid of support beams
which are held by the transverse supports (3) with fastening means (7) and which carry
or form a part of the shuttering, the post being arranged for transferring the mould
pressure exerted by the concrete on the mould shuttering in a casting operation through
the brace part (6) onto the base part (5), wherein at least one end of the brace part
(6) is displacable along the post (4) or base part (5), and means for varying the
angle between the post and the base part from a stright angle in both directions and
