Description

SYSTEM AND METHOD FOR JOINING MULLIONS TO TRANSOMS
System for joining mullions to transoms by less working. Technical field
The present invention refers to a system which enables to join, without any additional work, section bars in facades (to mullions and transoms, both semi-structural and structural), band frames, movable walls, and in general wherever mullions are to be joined to transoms with mitred joints. State of the art
Many systems are available to join mullions to transoms by using metal or plastic section bars. The most advanced systems provide for non-sequential joining between section bars by front insertion of transoms into mullions. This enables to prepare transoms before assembly, thus reducing the relevant costs. A further decrease in costs results from the fact that this method enables an easier assembly as compared to sequential joining systems. Unfortunately, the non-sequential front joining systems known today, although valid, have also quite high assembly and disassembly costs. In order to reduce these costs, many solutions have been designed, all of them trying to minimise the works to be performed on parts to be joined. Within this framework, we passed from works on mullions (aimed at obtaining notches to insert transoms) to works on transoms. The latter, being cut at the desired length, are milled or sheared in order to remove a portion of the outer wall at their ends. Thereafter, they are frontally inserted into side supports fastened to mullions by means of screws, and then locked to them by means of additional screws. Moreover, in order to facilitate the removal of condensation water through mullion gutters, transoms are milled again at the ends so as to obtain a projection at each of them in order to convey water in the said gutters. Finally, in order to obtain the soundest joining between mullions and transoms, sometimes mullion fins are also milled at the areas where the said projections are to be locked. It is clear that the costs to prepare mullions and transoms are very high, given the number of works to be performed: double milling or shearing of transoms, milling of mullions, double perforation of mullions (in order to obtain the holes to contain the screws of side supports and the screws to join transoms and mullions).
Moreover, labour is required for both the works on section bars and preliminary fastening of side supports.
Some front fastening systems which can be used instead of those described above provide for the use of joining elements that enable to avoid works on section bars. According to these new methodologies, transoms are cut at the desired length. Their ends are closed with plastic plugs that act as gaskets and dilatation compensators. Finally, transoms are joined to mullions by means of metal bars placed horizontally between transoms and mullions, and then fastened to them by means of screws. Metal bars are fitted into special transom channels or chambers. This creates a typical cross-shaped joint wherein the screws play an essential role for the purpose of tightness. In addition to reduced resistance to torsional stress in transoms, it is however necessary to perforate or shear both mullions and transoms, and this makes the preparation of the various parts expensive, even though to a lesser extent. Summary of the invention The aim of the invention is to make available to users a joining system for section bars that does not provide for any supplementary work in addition to cutting mullions and transoms in order to build facades, band frames and movable walls. A consequent aim is to enable front assembly and disassembly of section bars at very low costs with the relevant economic advantages.
These and other aims are achieved through the system being the subject matter of the present invention, which is characterised by the use of section bars, an insert and vertical spacers. The section bars that are suitable to obtain transoms have one or more channels, whose longitudinal axis is parallel to that of section bars, the longer axis being the vertical one.
The section bars that are suitable to obtain mullions have a seat, whose longitudinal axis is parallel to that of section bars, which is an ideal extension of transom channels. It can be divided into one or more channels by at least one fin, whose longitudinal axis is parallel to that of section bar.
The insert is a bar. It is almost entirely fitted into at least one of the transom channels, whereas one of its ends protrudes from the channel. The insert has two or more threaded holes, out of which at least one is located at the end protruding from transom channels. These holes contain screws or dowels. An insert portion can be divided into two or more fins parallel to transoms and joined between them at mullion.
The said screws or dowels are fitted into insert holes, and they prevent the insert from moving horizontally. In order to prevent heavy glasses or panels, or momentary loads, from provoking a downward mullion slip, special spacers are used.
A tight plug can close each end of the transom. It is formed by a body having the same profile as the transom, and a support protruding from the body in the opposite direction to the transom end. The support has one or more slits having a clear span of the same size as the insert body, and horizontal holes.
The use of the said insert to join transom and mullion avoids all works, except for cutting transoms. The latter are cut at the desired length in the workshop, and their ends are closed with plugs, if required, where inserts are placed. Therefore, the personnel in charge of the assembly of facades, band frames, movable walls, etc., will be sufficient to fasten inserts to mullions and transoms. The assembly is hence easy and quick, thus drastically reducing the costs and time required for these operations.

Detailed description of a preferred embodiment
The joining system according to the present invention in a preferred embodiment, which can be used in particular for continuous facades, provides for the use of inserts 1 , section bars suitable to create mullions 2, section bars suitable to create transoms 3, a first type of spacer 4, and a second type of spacer 5.
Each insert 1 is a substantially U-shaped plate, having a body 1.1 and two fins 1.2, 1.3 parallel to those of transoms 3. Four holes are obtained in insert
1 and more precisely two holes 1.4 in fins 1.2, 1.3 and two holes 1.5 in body
1.1.
The section bars suitable to create transoms 3 have a box-type body 3.1 and two channels 3.2, whose longitudinal axis is parallel to that of transoms 3, the longer axis being the vertical one. The two fins 1.2, 1.3 of insert 1 are fitted into the said channels 3.2, whereas body 1.1 protrudes from channels
3.2.
The section bars suitable to create mullions 2 have a box-type body 2.1 and a double seat 2.2, whose longitudinal axis is parallel to that of section bars, and is limited by arms 2.3. Each seat 2.2 is divided into two channels 2,4, 2.5 by a fin 2.6, whose longitudinal axis is parallel to that of mullion 2. On the wall of box-type body 2.1 faces fin 2.6, there is a longitudinal groove 2.7. On arms 2.3, a longitudinal groove 2.8 is also obtained.
A third section bar acts as a spacer 4. It has a body 4.1 from which two arms 4.2, 4.3 protrude. An arm 4.2 is equipped with a catch 4.4 placed on the outer face of arm 4.2.
A tight plug 6 closes the end of each transom 3. Each plug 6 is formed by a body 6.1 having the same profile as the tubular portion of transom 3 and a support 6.2 protruding from body 6.1. Support 6.2 is longitudinally crossed by two vertical slits 6.3 having a clear span of the same size as the two fins 1.2, 1.3 of insert 1 and two horizontal cross holes 6.4.
At the time of assembly, transom 3, which is already equipped with plugs 6 and inserts 1 , is frontally coupled to mullion 2. Fins 1.2, 1.3 of insert 1 are fitted into slits 6.3 of plug 6 and chambers 3.2 of transom 3. On the contrary, body 1.1 of each insert 1 is entirely fitted into channel 2.4 of mullion 2.
In order to prevent insert 1 from detaching from mullion 2, some dowels 7 are used. They cross holes 6.4 of plug 6 and threaded holes 1.5 of body 1.1 , thus engraving the walls of groove 2.7 of mullion 2, and creating horizontal seats that prevent further movements between mullion 2 and transom 3. Dowels 7 also play another role. Their tips use groove 2.7 as a fulcrum to lever on plug 6, thus obliging it to press against mullion 2, preventing the passage of water, and therefore ensuring a tight system. The insertion of body 1.1 of insert 1 into channel 2.4 prevents the accidental detachment of insert 1 from mullion 2. The contact between the walls of insert 1 and the walls of channel 2.4 prevents insert 1 - and therefore transom 3 - from rotating along its longitudinal axis.
Two additional dowels 8 prevent insert 1 from moving in channels 3.2 of transom 3. The said dowels 8 are fitted into threaded holes 1.4 of fins 1.2, 1.3 of insert 1 and engrave a wall of body 3.1 of transom 3. In order to prevent insert 1 from moving whenever transom 3 supports heavy or momentary loads, a spacer 4 is used. It is entirely fitted into the same channel 2.4 of mullion where insert 1 is fitted. Catch 4.4 on arm 4.2 fits into groove 2.8 on arm 2.3 of mullion 2, and prevent it from detaching. Spacer 4 is placed between one insert 1 and the insert above it. It creates a vertical distance between one transom 3 and the other, and supports them. Therefore, the time required to assembly the system is reduced, since scribing on mullions 2 is no longer necessary.
Assembly is sequential and upward oriented. After locking mullions 2 at the desired location, a first transom 3 is fastened to two contiguous mullions 2; thereafter, spacers 4 are fitted into two millions 2 above the first two inserts 1 , then a second transom 3 is fastened, and so on so forth until the facade is completed.
Alternatively, also a second spacer 5 can be used, whose double function is to create a distance between transoms 3 and to support the fastening elements of wings, if required. It is provided with two arms 5.1 , 5.2. The first arm 5.1 fits into channel 2.5 of mullion 2 which does not contain any insert 1 or spacer 4. Spacer 5 is fastened to mullion 2 by means of a gasket 9, which is provided with a relief 9.1 intended to occupy groove 2.7 on the wall of body 2.1
