Definitions

• This patent refers to a system for joining section bars used in fagades (both to mullions and transoms, be they structural or semi-structural) band frames, movable wails and in general wherever mullions are to be joined to transoms with mitred joints, without additional work.
• section bars used in fagades (both to mullions and transoms, be they structural or semi-structural) band frames, movable wails and in general wherever mullions are to be joined to transoms with mitred joints, without additional work.
• transom ends are milled once again, so as to obtain two projections, one on each side, directing the water into the above mentioned channel.
• mullion and transom preparation costs are very high, given the number of adjustments to be performed: double milling or shearing of transoms, milling of mullions, double perforation of mullions (in order to create the holes in which both the screws for the side supports and those needed for joining the transoms to the mullions will be fastened).
• a certain amount of labour is required both for the preparation of the section bars and the fastening of side supports in advance.
• transoms are cut to the desired length. The ends are then closed with plastic plugs which act both as gaskets and dilatation compensators. Finally, transoms and mullions are joined together with metal bars which are placed horizontally between the two and fastened to them by means of screws. The metal bars are fitted into special transom channels or chambers, creating a typical cross-shaped joint where screws are essential to keep the structure tightly fastened.
• the aim of this invention is to offer users a section bar linking system which does not require extra adjustments other than the cutting of mullions and transoms during the making of fagades, band frames and movable walls. Consequently, this invention also aims at enabling frontal assembly and disassembly of section bars at extremely low costs, thus offering great economic advantages.
• section bars which is the subject matter of this invention and which is characterised by the use of section bars, an insert and spacers.
• the section bars used for the making of transoms are provided with at least one channel (whose longitudinal axis is parallel to that of the section bars), developing vertically.
• the section bars used for the making of mullions are provided with at least two grooves whose longitudinal axis is parallel to that of the section bars and symmetrical to the central beams.
• each groove is provided with at least one coupling jaw, one holding jaw, and one inclined plane.
• Each groove can be divided into two channels by a sufficiently flexible fin, whose longitudinal axis is parallel to that of the mullion, which has to be provided with at least one coupling and one holding jaw.
• a projection creates the inclined plane, while at the end of the other channel a projection creates a housing.

• the insert may also be supplied with a guide beam placed perpendicularly to the insert's body and in the same direction as the connection beam. This guide beam may be provided with a terminal, preferably placed at its distal end and perpendicularly to the beam.
• the insert body may be subdivided into two or more sections which are parallel to the transoms, joining at the mullion.
• the insert is provided with two or more holes, threaded or not, at least one of which is to be located on the insert's body itself and another near the connection beam. These holes hold screws or dowels.

It may have diverse shapes and may or may not be provided with a coupling jaw to be inserted in at least one of the mullion's jaws. The spacer is inserted into a specific slot for fitting or in at least one of the channels.

• the edge facing central beams 2.3 of seat 2.2 is also inclined, thus forming another inclined plane, 2.8.

• a tight plug 5 closes the ends of each transom 3.
• Each plug 5 is formed by a body 5.1 having the same profile as the tubular portion of transom 3 and a support 5.2 protruding from body 5.1 itself.

• Jaws 4.3 couple with coupling jaw 2.5 and holding jaw 2.6 of seat 2.2 thus tightly fastening spacer 4 to mullion 2.
• Spacer 4 is placed between one insert 1 and the insert above it. Its function is not only that of holding the glass, it also creates a vertical distance between one transom 3 and the other and supports them. Assembly time is therefore reduced since scribing on mullions 2 is no longer necessary. Assembly is sequential and upward oriented.
• a first transom 3 is fastened to two contiguous mullions 2; then, spacers 4 are fitted into the two mullions 2 placed above the first two inserts 1 , then another transom 3 is fastened and the sequence continues until the fagade is completed.

Coupling jaw 2.5 and holding jaw 2.6 are placed on fin 2.4 itself; coupling jaw 2.5 facing channel 2.9 and holding jaw 2.6 facing channel 2.10. At the bottom of channel 2.10, placed towards the middle of mullion 2, a projection creates inclined plane 2.7. At the bottom of channel 2.9, placed towards the external side of mullion 2, a projection 2.11 , together with the walls of channel 2.9, creates housing 2.12.
• the section bar used as spacer 4 is formed by a body 4.1 and two beams 4.2 One of the two beams is provided with a coupling jaw 4.3 while the other beam ends with a fin 4.4 placed perpendicularly to the beam 4.2 itself. Housing 4.5 of body 4.1 holds a vertical gasket 8.

• Screws 6, which also pass through holes 5.4 of plug 5, are inserted into holes 1.6 close to connection beam and engrave holding jaw 2.6.
• Beam 1.8 guides screws 6 into channel 2.10. The locking with screws 6 is therefore performed by using the more central channel 2.10 and not channel 2.9 where beam 1.2 is housed.

It is provided with two beams, 10.1 and 10.2 which are fitted into yet another channel 2.14 of mullion 2 having a different position, lateral, and a different function compared to that of channels 2.9 and 2.10 which serve to lock both insert 1 and spacer 9.
• Spacer 10 is fastened to mullion 2 by means of gasket 11 which is provided with a relief 11.1 intended to occupy groove 2.15 within channel 2.14.
• a fourth example of realisation of the joining system here described uses an insert 1 , a section bar suitable to create mullion 2, of a second section bar creating transom 3 and of a spacer 12. Also in this case the details differ in shape but they have the same characteristics as the ones previously described. Fin 2.4 of mullion 2 is not provided with the inclined plane 2.7, the transom is only provided with one channel 3.2 and spacer 12 has two beams, 12.1 and 12.2, one of which is provided with a coupling jaw 9.3. Beam 12.2 of spacer 12 externally embraces mullion 2. Coupling jaw 12.3 of beam 12.1 of spacer 12 joins with holding jaw 2.6 of channel 2.10.
