BUILDINGS

The present invention refers to a construction system for structural frameworks of buildings, in particular for structural frameworks comprising pre- fabricated wooden elements.

Several constructions systems for structural frameworks of buildings are known in the art, in particular for structural frameworks comprising wooden pre- fabricated elements, which generally provide for the use of structural elements such as beams and pillars, which are installed in a yard, working them to modify their shape or length, and drilling them in order to couple them using both connecting elements, such as pins or pegs which work under shearing, and screws and structural metallic plates coupled with bolts, in order to mutually assemble the framework elements by working under compression.

These known construction systems has the problems of requiring further workings in the year to assemble the structural elements, which are further cumbersome to be transported.

Object of the present invention is solving the above prior art problems, by providing a construction system for structural frameworks of buildings which can be made using scarcely cumbersome structural elements, which are thereby easy to transport and to install, made with a limited number of standardized components, available in pre-arranged assembling kits, which do not require further workings in a yard for their installation .

The above and other objects and advantages of the invention, as will appear from the following description, are obtained with a construction system for structural frameworks of buildings as claimed in claim 1. Preferred embodiments and non-trivial variations of the present invention are the subject matter of the dependent claims.

It is intended that all enclosed claims are an integral part of the present description.

It will be immediately obvious that numerous variations and modifications (for example related to shape, sizes, arrangements and parts with equivalent functionality) can be made to what is described, without departing from the scope of the invention as appears from the enclosed claims.

The present invention will be better described by some preferred embodiments thereof, provided as a non-limiting example, with reference to the enclosed drawings, in which:

In particular, the first 11, the second 12, the third 15 and the fourth 16 structural elements are each composed of a panel having two opposite bearing surfaces 18, on which the structural elements 11, 12, 15 and 16 are adapted to be mutually abutted, when they are assembled to form the structural framework of the construction system 10 of the invention; the bearing surfaces 18 are those having height and width much greater than those of the side surfaces 19 of the panel, whose width is the same as the panel thickness.

Preferably, the construction system 10 for structural frameworks of buildings of the invention comprises the first structural element 11 inserted between two second structural elements 12 to form the pillar of the structural framework, and comprises the third structural element 15 inserted between two fourth structural elements 16 and between the two second structural elements 12 , preferably between two upper ends thereof, to form the beam of the structural framework, said first 11, second 12, third 15 and fourth 16 structural elements being assembled with their respective abutment surfaces 18 mutually in contact; the third structural element 15 is further abutted with its side surface 19 onto a side surface 19 of the first structural element 11, to form a structural engagement; further, the first structural element 11 is connected to the two second structural elements 12 by means of connecting elements, the third structural element 15 is connected to the two fourth structural elements 16 by means of connecting elements, and the third structural element 15 is connected to the two second structural elements 12 by means of connecting elements to form the structural framework.
