Description

INSULATING PANEL FOR CLOSING WALLS

WITH INTERIOR VENTILATED CHAMBER

Technical sector

 5

The invention is framed in the sector of the rehabilitation of buildings with a lack of specific thermal insulation or whose outer enclosure walls have a thermal resistance deficit.

It can also be applied in the construction sector of new construction as a termination coating on one-sided enclosure walls.

BACKGROUND OF THE INVENTION

 fifteen

The current objectives of quality, environmental respect and energy saving, require that thermal insulation be placed in the envelope of buildings to limit the thermal transmittance of enclosing walls, roofs and slabs, both in new buildings and in renovations of the existing ones.

 twenty

In the enclosing walls or facades, the thermal insulation can be located in three positions: inside the enclosure walls when they are formed by several factory or other sheets, or on the inside or outside of the wall when it is a massive sheet of enclosure.

 25

In the rehabilitation of buildings, the placement of the insulation on the outside face is the fastest, most comfortable and effective solution, because it avoids works inside. The solutions proposed to date consist of covering the enclosure walls with panels that can be grouped into two types:

a) Panels with thermal insulation, formed by a layer (for example 30 DE102012001081) or several layers of various materials (for example GB2135710, DE102007053380, CN202899326, IE86233, KR101265280 and WO2013088168), which are fixed directly to the outer wall of the enclosing wall with adhesives, mechanical anchors or screws of different types. The panel usually has a last layer that constitutes the surface finish of the façade or that allows placing that finish on it.

b) Panels that are fixed to the enclosing wall by interposing metal profiles to form a ventilated chamber in the backfill (for example 5 WO2013088075, CN 101769023, ES 2415777 and ES 2315211). These are the so-called curtain walls. The panel is usually the surface finish of the facade, and thermal insulation is placed between the profiles.

Some panels of the first group incorporate a closed air chamber inside it 10 to improve the thermal and acoustic insulation of the panel, but all of them lack a ventilated chamber. The panels of the second group do have it, but at a very high cost and occupying a lot of space towards the outside of the façade, because the ventilated chamber is formed with the metal profiles that hold the panels. The existence of a ventilated chamber is an important characteristic of the enclosure that improves the thermal and acoustic insulation of the façade.

 The insulating panel for enclosure walls with internal ventilated chamber that is proposed incorporates air grooves between the lugs of the insulation plate that make the function of ventilated chamber, without the need to place metal profiles, so the panel has a lower cost and occupies the minimum space to the outside of the facade.

Description of the invention

 25

The present invention presents a modular panel with internal ventilated chamber that incorporates thermal insulation and a surface finish on the façade finishing plate, designed to coat the walls of the building's façades or facades on the outside, in rehabilitation or in new construction.

 30

The panel consists of modules composed of three elements mounted in superimposed layers: an insulating plate of rigid material, a fiber mesh and several courses of finishing or finishing panels of the panel.

The plate of rigid insulation material is composed of two bodies that form a single piece: one, flat of constant thickness and another, from which protrude, between 2 and 6 centimeters, a few lugs that leave air between them to form a chamber that naturally ventilates the interior of the panel once installed. The lugs are distributed equidistant from each other in parallel rows, in such a way and size that four lugs correspond to each termination plate. The four edges of the flat body of the insulating plate have an overlap at half section to fit with the adjacent insulating plates.

On the lugs of the insulating plate a cross-linked mesh of fiber is adhered and, above, adhered to the mesh, the termination platelets. The function of the fiber mesh is to improve the adhesion between the platelets and the insulating material, to support the mortar that has to be applied later to reattach the joints between the platelets, and to prevent it from invading the insulating air grooves, for which, the mesh will have the openings of 5x5 mm maximum, suitable for the consistency and granulometry of the mortar.

Each module has only full platelets adhered to it, so that on the sides are the holes corresponding to the platelets that overlap with the adjacent modules. twenty

Each module is anchored to the outer face of the enclosing wall with at least four chemical or mechanical taps, inserting a rosette between the head of the plug and the insulating plate. Afterwards, the façade rigging is completed by gluing the platelets mounted on two modules, and the half plates in the corners and 25 in the encounters with the openings in the façade, and the tendels and the sores between the platelets are covered with cement mortar. .

The insulating panel for enclosing walls with internal ventilated chamber allows to install the insulation, a ventilated facade system and a finishing material 30 in a single operation, reducing the finishing completion times of the facade and, therefore, with a low cost of construction and placement. In addition, the panel occupies a very small total thickness compared to traditional ventilated facades, because it is placed directly on the wall of the facade without intercalating metal profiles.

Another advantage of the insulating panel for enclosing walls with internal ventilated chamber is that its exterior finish is with brick or stone plates, which gives it a traditional aesthetic, an important aspect that can be a factor in the case of rehabilitation of buildings. old

Description of a preferred embodiment

The insulating panel for enclosing walls with interior ventilated chamber is composed of modules (1) that can be manufactured by thermal insulation companies, facing brick, platelets made of natural stone or artificial stone. Several models can be presented, depending on the thickness of the insulation and the model of the finishing plate.

 30

The plate of rigid insulation material (2) can be made of high density extruded polystyrene or the like and is manufactured by injection into a mold. A piece is obtained that already includes the lugs (3) and the four edges at half section (7) to fit and overlap with the adjacent panels. The width and height of the insulating plate must be multiple of the standard modulations of the exposed brick platelets (24 x 6 cm is the most used), so that on each plate several whole platelets are distributed (for example, 8). rows of 4 columns) and that the weight of the set is manageable by an operator.

  5

On the lugs (3) of each plate of insulating material (2) a fiber mesh (4) of polyethylene or the like is glued, and then, taking advantage of the same glue and applying more quantity on the mesh (4), the platelets (5), leaving the holes (8) of the half plates (5) without putting on both sides to complete them later in situ once the modules (1) to the facade anchored. The thickness of the 10 platelets will be between 1 and 2 cm.

 The modules (1) can be supplied to work on pallets, and must also be accompanied by loose platelets (5), fixing blocks (9), rosettes and the grout between platelets (5). fifteen

 On site, the placement of the module (1) can be carried out by construction workers. Each module (1) is anchored to the façade walls by means of four chemical or mechanical taps (9), depending on the nature and condition of the wall, inserting a rosette between the head of the block (9) and the insulating plate (2). ) to avoid its punching. Once the wall is lined with the modules (1), the platelets (5) that overlap between two adjacent modules (1) and the half platelets (5) at the corners and encounters with holes are glued together, and the mortar is filled with cement mortar. the tendels and the sores between the platelets (5).
