Abstract

A prefab. wooden structure comprises a series of wooden rails (2) each contg. a longitudinal slot (3). The rails are secured to a concrete base (1) according to the plan of the building. A series of structural wooden panels having high mechanical resistance and good thermal and acoustical insulation properties contain grooves in their lower edges which locate over elongate strips (5) projecting from the slots. The lateral edges of the panels also contain grooves into which vertical strips engage to hold adjacent panels in alignment.

Description

 The present invention relates to the construction of @ buildings in law frame from prefabricated elements having qualities of mechanical resistance and thermal and sound insulation.

 One of the challenges of the present invention is to make one or more very economical constructions but with a very high level of thermal and phonic mechanical performance thanks to a control of the costs of fabrication and implementation, lased on a great simplification and speed of construction.

 According to the invention, the construction comprises a concrete screed, a smooth, anchored smoothing and trimming rule arranged on a layer of mineral wool with a waterproof screen. The anchoring in the screed is made using lag bolts, a streak of structural elements in the form of rectangular panels having qualities of micanic resistance and thermal and phoric performance.

intended to form the walls and the interior partitioning. the panels being adjusted and linked together using a series of profiles with a U-shaped section or a square section intended to be inserted in the grooves of the heald beams and in the grooves of the external faces of the frame of the panels. the panels being held together by stirrups. a chain made up of two beams @ois grooved and provided with profiles, the two beams superimposed and jointed in a corner chair at any junction of planes of different walls, the two beams being nailed between them and sun the high crosspiece panels arranged to form the walls. a roofing frame of the industrialized farmhouse type supporting the roof, a ceiling fixed to the base of the farmhouses and supporting the insulation of the roofing, an exterior panel.

with interposition of a rain screen. facing support and an interior panel. with interposition of a vapor barrier screen.

 Another characteristic of the invention aims in such a construction the production of doors and windows.

According to this characteristic. there are elements acting as a lintel or lighter made and connected in the same way as the wall panels.

- Doors and windows openings are inserted between the elements described above panels. lintels, lighters, means being provided for the Assem @ lage of these adapter elements. sleeves, support pieces. dormant. series of seals @ tee.

 The invention will now be described in more detail with reference to a particular embodiment given by way of example and shown in the accompanying drawings.

 To make a construction according to the invention.

preferably prefabricated structural elements such as those described in the French @revet application n are used in the name of the applicant. these structural elements being formed of boards assembled by straddling in a grid network so as to form a lattice @ois inserted in a frame @ois. panels of thermal and sound insulation materials arranged in 2 or more layers in the risille enclosing air voids.

 Such panels have the advantage of being very resistant and of having excellent thermal and sound insulation qualities.

 According to the invention, the walls produced using juxtaposition of structural elements are rigidified by the same structural element placed in a plane perpendicular to said wall and anchored and chained according to the same smooth anchor beam and high beams chaining, these are assembled in a corner chair with the healds of the chaining of the wall.

 Pr @ ala @ lement to the assembly of the panels one realizes a screed in @ éton (1) on which one fixes a smooth @ass of anchoring in @ois (2) with groove (3) with interposition of a layer of mineral wool with sealing screen (4), arranged so as to constitute the general plan of the house.

a profile (5) being inserted in the groove (3) on the rail (2) by overlapping sun the profile (5) is engaged by their lower edge the structural elements @ois (6) dan @ the sections of which we previously @lement made of grooves (3).

We nail the cross @ass of the framing sun the smooth anchor using carpenter's points, these panels being linked together at the framing by staples for example.

In the corners of the construction, two panels overlap but do not have any guide by profiles and are only held together by staples or plates (7) @ metal points or laws acting as connectors.

To carry out a cha @ nage ensuring the mechanical rigidity of the assembly, a smooth lère (8) @ois grooved on its lower and superior face on the profile (5) previously engaged in the groove of the upper edge of the panel, we nail this smooth edge @ois (8) using carpenter's tips on the upper edge of the frame of the panel, we engage by its underside a smooth Zeme @ois (9) grooved on its lower face on the profile (5) previously disposed in the groove of the upper face of the 1st smooth @ois (8) this 2nd smooth @ois (9) is nailed using carpenter's tips on the upper face of the arm (8).

In the corners of the construction, the beam (8) and the beam (9) superimposed, are assembled in a corner chair.

To make the frame we use industrialized farmhouses (10) nailed by their holes on the rail (9). and we put the cover (11).

To make the openings, the juxtaposition of the panels (6) is interrupted to reserve empty spaces. these gaps are closed by placing the doors (12). windows (13) and closures (14) by fastening frames and frames of these works on the frame of the panels (6). with use of sleeves, adapters. rebates. joint covers, supporting parts, series of joints, etc. if necessary.

A panel (15) is attached to the outer covering with the interposition of a rain barrier (16) on the structural elements designed to reserve a ventilated air space (17) on the outer wall.
A panel (18) is fixed on the inside on the structural elements with the interposition of a vapor barrier (19)
Of course, the invention is not limited to the embodiment described and shown, it is possible to add to it name @ many modifications of detail without departing, for this, from the scope of the invention.
