FR2624540A2 - Non-reusable shuttering device for simultaneous execution of all elements for framing an opening including support and fixing for shutter hinges - Google Patents

Abstract

Unique shuttering device characterised by a ready-to-use BLOCK in a destructible lightweight material, fixed and inserted as it is into the brickwork at the same time as the structure of the building is formed, allowing the complete and finished framing of OPENINGS, doors and windows in traditional structures to be formed by simple successive operations of pouring concrete or mortar. The BLOCK is made to the appropriate dimensions for each aperture and also allows the most varied architectural motifs to be formed. When the shuttering is struck, which is done by destroying the BLOCK, the framing of the OPENING is complete; i.e.: - the upper lintel 1 - the two vertical side jambs 2 - the window sill with throat 3 4 - the external arris of the framing 5 6 - the internal shoulders for fixing joinery without the addition of plugs 7 8 - the fixing for hinges and internal and external shutters 9 10.

Description

DESCRIPTION
The description which follows relates to patent No. 86 18 481 of December 30, 1986 to which transformations have been made.

 The most important transformation comes from the modification of the mode of integration of the support part in the general device.

From now on the support piece n1 is no longer integral with the
LIGHT BLOCK, neither molded on the flat site before the said BLOCK is installed [page 2 - 3-) line 21 to page 3 line 3 of the previous deposit]. The general device is therefore somewhat modified as well as the implementation.

So
In traditional constructions, the making of BAY frames is, of all operations, those which are the most delicate to carry out and which require the best care. It is in this place that the aesthetics and the technique mix and where particular connections are brought together between masonry, carpentry and finishes. It is also the qutapparraissent the first poor workmanship.

 For many years, 'entrepreneurs, technicians, inventors have been looking for the most suitable formulas to reduce the time taken to make the BERRIES and increase the quality of the work. This is how precast concrete frames appeared, metal frames incorporating windows and shutters as well as a certain number of reusable or non-reusable formwork systems making it possible to integrate as many functions as possible in a single operation.

 Many systems are registered and patented. Today they are bringing significant improvements to traditional constructions.

 The object of the invention relates to a single formwork device, ready to use, made of light destructible material, for the realization of the window frames, doors and windows, intended for traditional constructions whatever their use (villas , apartment buildings, offices, administrative buildings ...).

What distinguishes this invention is that the unique formwork device, ready for use, comprises by its shapes and attributes, all the functions allowing, with very high precision, by simple successive operations of filling concrete or mortar, without additional formwork or additional elements, without any particular assembly on site, to achieve the appropriate dimensions for each opening
the upper lintel (1)
+ the two vertical side cheeks (2)
+ window sill (3) with rejingot (4)
+ the outer edge of the frame (5) (6)
+ the inner shoulders (7) (8) for the
fixing the carpentry without adding
furs
+ the sealing of the hinges (9) (10) of the shutters or
shutters
The device also makes it possible, thanks to additions, bosses or profiled impressions, to produce variants and architectural patterns such as
lintel belted or mixed whatever the sketch.

rebates or embrasures for shutters or
shutters.

decorative molded facade patterns
outer periphery of the bays (framing
peripheral) projecting or recessed.

 The device finally makes it possible to produce, at the appropriate dimensions (and without prohibitive additive cost), stiffeners at the periphery of the RACKS (11) for earthquake resistance.

 What distinguishes this invention is also that this unique formwork device, ready to use, is inserted into the masonry at the time of assembly of the structural work and becomes an integral part thereof before fulfilling its formwork or molding function .

 The device according to the invention therefore consists of a BLOCK made of light destructible material (for example expanded polystyrene), comprising in the lower part a recess (18), in the lateral parts and in the upper part of the notches (12) (15) to variable profiles intended to carry out the formwork and the molding of all the elements of the window frame.

 The BLOCK is inserted into the masonry during the assembly of the structural work. The recess and the notches which cover the masonry serve firstly as a guide for positioning the BLOCK in the masonry, then as a guide for mounting the masonry around the BLOCK.

For this purpose the BLOCK includes above the rejingot
and in its rear part an opening (20) of
sufficient dimension to allow pouring of
support. This opening is completed by a
beach (21) which is used for depositing mortar or concrete
before it is introduced into the recess (18)
through the slot (22) of the rejingot.

Implementation.

5 *) In order to provide the BLOCK with the most
complete, it is delivered to the site
fitted with hinges (30) shutters or blinds
in their final position (9). These hinges are
themselves housed in recesses (27) while
that their sealing lug (31) in length
is attached to the rear part (36) of the
BLOCK. The originality and interest of the system is
that the hinge / lug assembly is
securely held in its final position
during transport, storage and assembly of the
BLOCK. There is therefore no risk of workmanship
nor deviation.

Alternatively, the hinges can also be
replaced by
sockets (32) for fixing hinges to
tackle (10)
In this case the dimples (27) are replaced
by holes (28). Through these
holes are threaded with threaded rods (23) which
used to hold sockets or shims
before pouring.

wedges (cubes, pyramids, pears) intended
with the traditional sealing of the hinges of the shutters
or shutters.

6) To improve with regard to technical requirements or
architectural quality of finish or the
quality of preparation of the different surfaces,
the walls of the recess and the notches (12)
(13) (14) (15) (16) (17) (18) may be
factory coated with additional products
(sheets or films) and / or all products of
surface treatment (oils, greases, gels).

The BLOCK mounting operation is simple
The mason climbs the light wall (25) normally to the level (24) of the underside of the support (3). Tolerance is possible.

Then it goes up 1 to 2 rows of agglomerates on each side of the future BAY. The opening thus formed corresponds to the width in the table + about 15 cm for a
Normal BAY and in the width of the table + about 35 cm for a BAY with earthquake-resistant reinforcements.

 The BLOCK is then presented above; it is lowered to the correct height thanks to the mark on the support as well as the mark on the level of the lintel; it is positioned laterally with respect to the future axis of the BAY. This whole operation only takes a few minutes. The recess (18) and the opening (26) as well as the notches (15) and the openings (29) are calculated as accurately as possible so that the BLOCK is freestanding in contact with the masonry.

The mason has a chevron horizontally in the lower external part and a horizontally chevron in the lower internal part (that is to say at the level of the support). The 2 rafters are pressed against the BLOCK using 2 clamps. The BLOCK is thus firmly held in its final position before pouring
The support is poured first and if possible vibrated; the concrete or mortar is introduced through the slot (22) as indicated above.

 The masonry is then mounted around the BLOCK. The casting of the cheeks (2) or of the seismic reinforcements (11) is carried out at the same time as the mounting of the masonry, that is to say as and when.

 The lintel (1) is poured at the end of the operation.

 The formwork is removed by destroying the BLOCK by all appropriate means compatible with the requirements of the environment, respecting the drying times.

 The walls of the formwork being insulating they allow to limit during the setting of concrete and mortar the effects of frost or the effects of heat.

 The joinery is installed later, at the appropriate time, on a joint or bead of mastic. The fixing is reinforced If necessary by sealing lugs or distributed dowels. This device removes any additional furs that have become useless.
