All-wooden faÇade system with protective lamella

Abstract

An all-wooden façade system featuring a protective lamella, which ensures long service life and resistance to decay without requiring an additional non-load-bearing aluminum profile. The invention achieves this by using a protective lamella made of acetylated wood or another moisture-resistant material, directly connected to the load-bearing wooden profiles by a detachable or non-detachable joint, forming a unified structural component.

Description

Technical Field

[0001] The present invention relates to the field of construction engineering, specifically to the structural design of slatted and structural grid glazed or partially glazed facades intended for architectural and building applications.Background of the Invention

[0002] In current practice, glazed grid façade systems commonly employ aluminum profiles with a thermal break or wooden supporting grids supplemented by additional aluminum façade profiles serving as non-load-bearing, moisture-resistant components. These aluminum elements typically include grooves for seals, glass carriers, and similar fittings.

[0003] However, such designs suffer from several drawbacks, including structural complexity, high heat transfer coefficients (U-values), and adverse environmental impacts associated with aluminum extraction and processing.

[0004] Accordingly, there exists a need for a simplified, environmentally sustainable façade system that provides high durability, resistance to decay, and reduced thermal bridging-while eliminating the use of auxiliary aluminum components.Summary of the Invention

[0005] The aim of the present invention is to provide an all-wooden façade system featuring a protective lamella, which ensures long service life and resistance to decay without requiring an additional non-load-bearing aluminum profile.

[0006] The invention achieves this by using a protective lamella made of acetylated wood or another moisture-resistant material, directly connected to the load-bearing wooden profiles by a detachable or non-detachable joint, forming a unified structural component.

[0007] In the area susceptible to condensation or water ingress, the system effectively prevents wood degradation caused by moisture exposure.

[0008] Advantageously, the protective lamella is further provided with grooves for base sealing elements designed for transparent or opaque infill panels.Brief Description of the Drawings

[0009] The invention will be more clearly understood from the accompanying drawing, in which: FIG. 1 shows a cross-sectional view of the façade system with the protective lamella, illustrating the connection between a glued laminated timber beam and an acetylated or otherwise decay-resistant wooden lamella.Detailed Description of the Preferred Embodiment

[0010] An exemplary embodiment of the all-wooden façade system with a protective lamella comprises a load-bearing profile (1) composed of a glued laminated beam (2) made from lamellas of common wood species, such as spruce or larch.

[0011] Attached to the beam is at least one protective lamella (3) made of acetylated or otherwise modified wood, or another type of decay-resistant timber, the lamella being joined to the beam by a bonded joint (4).

[0012] In the area (5) where condensation or water infiltration may occur, this configuration ensures effective protection of the load-bearing profile (1) against degradation caused by moisture.

[0013] The protective lamella (3) is further formed with one or more grooves (6) accommodating base seals (7) for a transparent or opaque infill (8), thereby ensuring proper sealing and longterm system integrity.Industrial Applicability

[0014] The present invention is particularly applicable in the construction industry, especially in the manufacture of glazed façade systems, where sustainable, high-performance, and aesthetically consistent materials are required.

Claims

1. All-wooden façade system with a protective lamella and a transparent or opaque infill, characterized in that it comprises a load-bearing profile (1) including a wooden beam (2) and at least one protective lamella (3) made of acetylated wood or wood resistant to decay, the beam and lamella being connected together by a detachable or non-detachable joint (4), ensuring protection of the load-bearing profile (1) against degradation in the area (5) of the façade system where condensation or water ingress may occur.

2. Façade system according to claim 1, characterized in that the protective lamella (3) includes at least one groove (6) for a base seal (7) of a transparent or opaque infill (8).

3. Façade system according to claim 1, characterized in that the non-detachable joint (4) is formed by adhesive bonding.
