 System of rigid unions
standardized for metallic structures of buildings by means of the
utilization of pieces of standard union
What is obtained
It transforms the structure of the building into a game to mount.
It increases the
inflexibility of the structure in spite of using more light profiles with
notable saving of material.
It does not produce arrows and takes advantage of the material to
the maximum that is employed at condition state semi rigid.
The process of mechanization in workshop is minimal and in some cases
unnecessarily.
The assembly screwed in work is rapid and easy to execute.
The structural design is
simple when equaling itself the types of union that resist but that the
bars.
 The calculation is very simple and within reach of any professional.

Description
:
The structure of the
building consists of:
-
The metallic profiles: The types H and I standard
-
The elements of union: screws of high resistance
-
The prefabricated units for the connections.
These are the main
innovating element of the system because it makes possible the
standardization of the solutions and its fast application, which can get
considerably to reduce to the use of manual labor and time in the process.
Characteristics of the element that is introduced for
the execution of the unions
It is an element that
gives rigidity that is placed between the wings and the soul of profiles
H to both sides of he himself. Its basic form is in U or tubular.

By means of this
piece a remarkable degree is obtained that “rigidity” in the system to
transmit flexible moments to the other bars of the knot, as much in the
plane of the porch like in the cross flow plane to this one, and its length
is the necessary one to be able to connect to the union the variety of
profiles used in the market.(See Image)
In order to place the piece in its place, a
subjection to the profile takes to end base that “positions it” in the
suitable place, whereas the connection of the other profiles is made by
means of the use of plates of anchorage welded to the profile or “plates of
head” that are connected to the knot by means of some of the types of
existing screws in the market, but the greater effectiveness is obtained
with the pre-stressed ones of high resistance. (See Image)
