Description:
METHOD FOR THE CONSTRUCTION OF A BUILDING COMPRISING WOODEN WALL PANELS AND WOODEN FLOOR PANELS

The present invention concerns a method and relative means for the construction of a building comprising wooden wall panels and wooden floor panels.

A method and relative means for the construction of a building comprising wooden wall panels and wooden floor panels are known.

The international patent application no. PCT/IB2016/054005, by the same applicant, discloses a method for the construction of a building comprising wooden wall and floor panels, for example of X-LAM ("Cross Laminated Timber") type, comprising the steps of:

- providing a plurality of wooden panels capable of defining the walls and/or the floors of a building;

- providing the sides of said panels with holes along axes substantially parallel to the plane of the panel;

- providing a connection joint for said wooden wall panels, wherein said step of providing a connection joint comprises the steps of:

- providing a plurality of internally threaded ferrules;

- permanently engaging the ferrules in the holes of the panels;

- providing a plurality of securing brackets provided with holes or slots for the passage of bolts;

- securing the brackets to the panels engaging the bolts in the ferrules;

- providing a node provided with holes or slots for the passage of elements for securing the brackets to the node, wherein the node comprises a guide sleeve; - providing an interconnecting rod;

- associating said rod with a plurality of nodes inserting the rod into the guide sleeve of each node, or engaging one end of the rod in the foundation of a building.

While the invention forming the subject matter of the aforesaid international ap- plication represents an improvement with respect to the state of the art in the construction of a building comprising wooden panels, it concerns a method of vertical connection, provided in points (connectors glued horizontally at the center of the walls) secured by means of bolts to the box-like steel attachments. Moreover, in the building structure constructed with the aforesaid prior art method the structural elements for attaching the panels are not completely concealed inside the walls and floors made of X-lam, and therefore do not protect all the steel parts from fire and corrosion, and do not eliminate electromagnetic fields.

On the other hand, building structures constructed with the aforesaid prior art method are subject to permanent structural damages if subjected to seismic events, as the metal structural attachment elements undergo irreversible deformation that makes it difficult, if not impossible, to restore the structure to condi- tions of safety and habitability.

The main aim of the present invention is to provide a method and the relative means for the construction of a building comprising wooden wall panels and wooden floor panels, which makes it possible to:

- create a continuous vertical connection for the entire height of each wall of the building, with respect to metal reinforcing means, so as to obtain a continuous connection on the entire height of the walls, for example made of X-lam, making the construction system solid in its entirety;

- ensure improved air-tightness and moisture-tightness, reduction of noise and vibrations in the building constructed;

- protect all the metal parts of the building constructed against fire and corrosion, and eliminate electromagnetic fields;

- create an anti-seismic building elastically scaled with unitary behaviour factor (q = 1 ), so as to protect human life and heritage;

- create a building in which the structural materials used are environmentally friendly (90% wood) and 100% recyclable.

In view of these objects, the present invention provides a method and relative means for the construction of a building comprising wooden wall panels and wooden floor panels, the essential characteristic of which forms the subject matter of the main claim, while further advantageous characteristics of the invention are described in the dependent claims.

Moreover, the method of constructing a building according to the present invention comprises the steps consisting of providing said reinforcing element, and said further reinforcing element AR, with fixed spacer means, which co-act to create the free cavity between said reinforcing element and said first wall form- work cavity CA, respectively between said further reinforcing element AR and said further wall formwork cavity CA, and perform automatic centering of said reinforcing elements in the wall formwork cavity CA, respectively in said further wall formwork cavity CA, providing said free cavity IT.

Moreover, the method for the construction of a building according to one or more of the claims, comprises the steps of:

providing said reinforcing element AR, respectively said further reinforcing element AR, by assembling at least one pair of metallic bars with improved adherence and an intermediate perforated coupling plate (Figs. 8 and 9).

As a result of the above, with the method for the construction of a building comprising wooden wall panels and wooden floor panels it is possible to achieve the objects set forth in the preamble in a simple and efficient way.

In particular, the present invention provides a method and the relative means for the construction of a building comprising wooden wall panels and wooden floor panels having the following advantages:

- the building constructed comprises a continuous and vertical connection for the entire height of each wall by means of the use of suitably shaped metallic bars with improved adherence and a hardening adhesive, for example, two- component epoxy resin, injected from below. By injecting the adhesive from be- low, a continuous connection on the entire height of the walls, for example made of X-lam, is obtained, making the steel profile integral with the X-lam walls and the building constructed solid in its entirety; - the building constructed ensures air-tightness and moisture-tightness, as well as reduced noise and vibrations;

- all the metal parts of the building constructed are protected against fire and corrosion, and the electromagnetic fields are eliminated;

- the building constructed is anti-seismic and elastically scaled with unitary behaviour factor (q = 1 ), allowing human life and heritage to be protected;

- the building is constructed with environmentally friendly (90% wood) and 100% recyclable materials.

Moreover, from a first economic evaluation, the method forming the subject mat- ter of the present invention is more economical to implement with respect to the aforesaid prior art method and with the same efforts. This saving is the result, at least in part, of the limited number of component elements and consequent reduction in warehouse logistics, and also of drastic decrease in assembly times, easy availability of the component elements, as they can be found on markets worldwide, and the use of component elements that do not require special processing.

A further advantage of the method according to the invention derives from the fact that injection of the hardening adhesive, for example two-component epoxy resin, from below is also applied to the connection of the bars or pins with im- proved adherence placed along all the walls, to support the tensile and shear stresses, as said bars are provided with centering ferrules that facilitate injection of the adhesive. By injecting the adhesive from below and not from above, as provided for in the prior art method, this ensures complete filling of the chambers for housing said bars or pins provided in the walls, with venting of the air from above. This arrangement, besides ensuring the continuity of the walls, enables assembly to take place also in situations in which it is not possible to operate from outside (sites in which the new structure is inserted inside existing stone or masonry buildings, such as in cases of post-earthquake operations, fulfilling the requirement to protect existing buildings).

Lastly, with the method according to the invention it is possible to avoid the use of external scaffolding by means of the use of adequate safety systems during structural assembly.
