DESCRIPTION

Multifunctional Support Structure for Wooden Building Walls

Technique field

In wooden constructions, even of the multi-story type, with the aim of securing the wooden elements of the wall to the plinth, slab or concrete floor, with special reference to the joints in contact with the wall-foundation, the state of The technique reveals a series of connection systems, all of them referred to as union brackets, through the interposition of static insulating elements of various kinds, adapted to protect from the rise of humidity due to stagnation and capillarity from concrete to wood.

This is due to the fact that the interface constitutes the part of the wooden constructions most vulnerable to humidity, due to the susceptibility of the wood to decomposition, in said arrangement particularly exposed to humidity.

Even in the cases in which the prior art provides an interposition of more complex elements than simple waterproofing elements, as for example illustrated in document WO2014 / 076526A1, the elements made in this way are still within the conceptual and resolutive scope of the condition. static protection, only more articulated in relative implementation, so the problem is not radically resolved.

Figures 11 and 12 of document FR 2223524 disclose a dry wall to be fixed between a roof and a foundation by means of upper and lower support elements. Screws or bolts are fitted into the lower support elements and are attached to the wall so that their height can be adjusted. Consequently, the bottom of the wall is always away from the foundation.

Document US 4656794 refers to an apparatus for providing double covers or liners composed of a U-shaped support part whose upper ends form seats for coupling an upper strap, while the base of said support part is adapted to be mounted on a pre-existing roof deck.

A more articulated solution is provided in US2002 139059A1, but it is primarily intended to eliminate infiltration and accumulation of rainwater in wood construction products placed on site and does not have a structure adapted to support wooden construction walls. with static charges on various floors. Specifically, this patent document describes a building construction comprising a wall, a concrete foundation and a multipurpose support structure interposed at an interface between the wall and the concrete foundation, said support structure comprising a metal section of a quadrilateral shape. that has a flat base and that has lateral walls that project upwards, the upper part of which provides flat coplanar supports that delimit an open upper intermediate space, whereby said open upper intermediate space is occluded by the base of said wall that rests on said Coplanar supports of the section to create a continuous air chamber that runs along the entire perimeter of the wall for air circulation in contact with the base of said wall.

Objects of the invention

To this end, a concept according to the present invention is provided with the main objective of providing an adapted solution to radically solve the problem related to the accumulation of moisture at the concrete-wood interface of the walls of wooden buildings and with respect to to their deterioration.

Another object of the present invention is to achieve the previous object through a solution that is easy to implement and place on site, also suitable for application in multi-storey buildings and that supports structural loads of any condition and type in wooden constructions.

Another object of the present invention is to achieve the above objectives by means of a solution that can be implemented without substantial revolutions of any kind in design and construction techniques, as well as modular and multipurpose solutions with respect to design and implementation requirements.

A further object of the present invention is to achieve the above objectives through a solution that is simple and efficient, safe to use and relatively inexpensive considering the actual results achieved with it.

These and other objectives are achieved by the construction of the building according to claim 1.

Description of attached drawings

Other characteristics and advantages of the construction of buildings according to the present invention will be more apparent from the claims and the following detailed description of a preferred but not exclusive embodiment thereof, represented solely by way of non-limiting example with reference to the attached drawings, in which:

Figure 1 illustrates a perspective view of an embodiment and the placement on site of a multipurpose support used in the construction of a building according to the present invention;

Figures 2 to 5 illustrate, respectively, a plan view, front elevation, rear elevation and side view of the exemplary embodiment and of the placement in the work object of Figure 1.

Static description of the realization

With reference to such figures and in particular referring to figure 1, an exemplary embodiment and the placement on site of a multipurpose support used in the construction of buildings according to the present invention, constituted by a successive plurality of metal sections, preferably made of stainless steel, respectively indicated in its entirety with 2, having a substantially isosceles trapezoidal cross section in the described embodiment, indicated in its entirety with 1.

With reference to said cross section, the larger base 3 is intended to rest on a concrete foundation and / or support, plinth, slab or floor (not illustrated) supported therein and fixed for example by embedded bolts (not illustrated) partially in the concrete and pass through the lower grooves 4.

The sides or edges 5 are inclined inward at the top and apically have respective coplanar flat supports 6 that delimit an open upper intermediate space 7 of the section 2 juxtaposed outwardly and in communication with the internal compartment 8 delimited by the section 2.

One of the flat supports 6, preferably the one facing outwards at the place of placement, has a perforated bracket 9 for fixing a wooden wall, schematically illustrated in a relative segment and indicated in its entirety with 10, the base of which 11 it is dimensioned with a thickness corresponding to the transverse extension of the coplanar supports 6 of sections 2 and occludes the open upper intermediate space 7 of sections 2.

The succession of sections 2 extends linearly with successive mutual communication of the respective internal compartments 8, also angularly, with joints 12, for example, 45 °.

The internal compartments 8 of two adjacent sections 2, even angular ones, are thus placed in communication to create a continuous air chamber 8 that runs around the entire perimeter of the walls 10 below them and, preferably, even under the internal walls.

Along said air chamber 8 are preferably arranged openings that communicate with the outside, not illustrated, preferably adequately protected by grid elements, possibly also connectable to ventilation means, not illustrated, adapted to force a flow of air into circuit 8, for the functions described below.

Dynamic description of the realization

Thus, having completed the static description of a preferred embodiment of the multipurpose support structure for wooden construction walls obtained according to the present invention, the dynamic description, or relative operation, is set out below:

The section, preferably made of steel, can be cut, modular and / or to size, and can be manufactured in various thicknesses of the component material and the width of the product, to adapt to the loads and dimensions of the walls.

Placed on site in a plurality of modules and / or sections 2 cut to size, they constitute a support structure that delimits the entire perimeter base and, preferably, also the base of the interior walls of the wooden building, contingently screwed through the grooves 4 of the larger base 3 thereof or without clutch fixed to the slab, or plinths or curbs made of foundation concrete, bricks or stones or foundations.

The walls 10 placed in situ on the module circuit are fixed to the brackets 9 and supported by the outer coplanar supports 6, interconnecting with the bases 11 of the same the upper longitudinal openings 7 of the sections 2, or in direct contact with the inner chamber 8 of sections 2.

This contact with the air, preferably circulating and renewing itself in the conduit thus defined, providing an adequate number of openings suitably protected against the entry of insects and rodents, obtained at the bases 11 of the wooden walls 10 at the point most exposed to stagnation. humidity, already protects the wooden elements from decomposition over time.

Furthermore, in cases where the circulation is forced in the duct thus defined, simply by associating to the openings, possibly conceived in a contingent manner with suitable accessories, air flow generators, also possibly functionally associated in a stable way and possibly even automatically triggered at preset time intervals via timers of any known type suitable for the purpose.

By suitably dimensioning the sections 2 and the relative circuits, they can also be used to support multi-story buildings with the loads exhibited by such prior art constructions.

They can also be applied above and below the concrete and / or brick floor parts possibly interposed between the floors defined by the wooden walls.

According to an extremely advantageous application, the sections 2 that constitute the multipurpose support structure for wooden construction walls according to the present invention, can be used to reinforce concrete curbs, embedding them in the formwork completely integrating the relative external shape, so that Concrete curbs are modeled with a straight quadrilateral, of a trend-square shape with appropriate angles, reinforced with the sections 2 according to the present invention embedded flush thereon after modeling.

Thus, section 2 remains empty internally, to perform its aeration functions, and externally embedded in the concrete, thus acquiring considerable resistance to loads, through the outer fins or supports 6 that support the walls 10 that rest on the concrete that surrounds them and rest laterally with respect to it, providing the concrete with compressive strength.

Alternative realizations

It is obvious that alternative embodiments, still within the innovative concept of the embodiment illustrated above and claimed below, the construction of the building according to the present invention can be implemented through equivalent technical and mechanical solutions or other complementary solutions can be provided, applying the same case to all components that can be modified in a way suitable for the purpose.

In particular, the cross-section of the sections 2 can be obtained in various shapes suitable according to the purpose, without or with different shape and structure of the supports to support the walls, which can also provide bridges or grid elements, leaving an area of suitable interface between the base of the wooden wall and the air channel that can be occluded by the base of the wall.

Advantages of the invention

As can be seen in the previous detailed description of a preferred embodiment, the construction of buildings according to the present invention offers advantages corresponding to the achievement of these and other pre-established objectives:

In particular, the multipurpose support structure used in the construction of buildings according to the present invention provides a simple, multipurpose and modular solution concept that is quick to place on site and is relatively inexpensive, especially considering the advantages obtained and the future interventions of maintenance and restoration that are reduced over time, to really prevent the deterioration of the wooden walls at the interface with the relative bases:

The structure also makes it possible to enhance the isolation and solidity of this type of construction, meeting the requirements of their lightness and without being in any way substantially invasive from an aesthetic point of view.
