Abstract

The invention relates to a structure and anchoring system for ventilated façade plates and assembly thereof based on a structure formed by a U-shaped anchoring base which is fixed directly on the work either by screws or by extendable wings which are inserted in grooves existing in the brick, two latches for the provisional positioning of the vertical load-bearing structure which latches are clipped on the anchoring base and, once the load-bearing structure is plumbed, are definitively fixed by screws and the vertical load-bearing structure made in a metal profile provided with three longitudinal tracks and with a rear channel in which an insulating material is coupled. The securing assembly for securing the cladding plate by clipping for the standard or three-dimensional installation of.the façade is carried out with two types of clamps, one for composite plates and the other for mineral plates, assembled in a standard or three-dimensional clamp holder, all secured to the structure by means of the clamp holder base. Both the structure and the assembly for clipping the cladding plate generate a four (planar façade) or five (three-dimensional façade) axes mobility, perfectly adjusting to the cladding plates.

Description

Object of the Invention

The invention, as the title indicates, relates to a metal structure, an anchoring system for cladding plates made of different materials and a way of installing both for making lightweight ventilated façades. The metal structure is basically formed by vertical tubular load-bearing structures which are fixed to the building by means of specific anchoring elements and cramps in the shape of a clamp which allows adjusting the point for securing the plates along three axes in their standard installation and along five axes in their particular installation. The plates, which can be made of different materials, have a profile which is pressure housed inside the clamps, being firmly secured without needing screws, rivets or adhesives.

Background of the Invention

There are currently structure systems for lightweight ventilated façades characterized by a horizontal and vertical framework needing a precise layout and installation which absolutely conditions the subsequent assembly of the cladding plates. There are no systems or ventilated façade structures in which each point for securing the plates can be independently adjusted along three and five axes.

Inventive Step

The advantageous usefulness of the invention, as the preliminary paragraphs of this specification has summarized, is that of providing an adjustable structure along three or five axes, formed only by vertical load-bearing structures with a system for adjustably fixing the load-bearing structure to the building and a system of adjustable clamps for securing the cladding plates which are assembled under pressure without needing adhesives, rivets or screws allowing to easily put the plates on again.

Description of the Invention

The invention is therefore essentially based on a structure made with vertical profiles adjustable along two axes and on a system of clamps adjustable along two or four axes for pressure clipping the cladding plates. The structure object of the invention is formed by a U-shaped steel work anchoring base which is fixed directly on the work either by screws housed at the bottom of the U in the perforations existing for the purpose, by screws located in laterally extendable tabs or by equally extendable wings also located at the bottom of the U which are inserted in grooves existing in the brick. A second element is two latches, one on each side of the work anchoring base for the provisional positioning of the vertical load-bearing structure which are clipped on the anchoring base and which are used for securing during the process of laying out the vertical load-bearing structure and once it is plumbed it is definitively fixed by screws. Another element of the structure is the vertical load-bearing structure made in a metal profile provided with three longitudinal tracks, two side tracks in its rear part for their fixing on the anchoring base by means of the positioning latches and another front track for placing the clamp holder base as well as a rear channel in which an insulating material is coupled. This system for installing the vertical load-bearing structure offers the possibility of adding anchoring bases according to the needs of the work without having to disassemble the already installed elements. There are two variants of the securing assembly of the plate which are the securing assembly for a standard installation of a planar façade and the securing assembly for a three-dimensional installation with their respective clamp models for composite plates and mineral plates. In its first variant (planar façade), the standard securing assembly of the plate is formed by three elements: the clamp for the composite plate or the clamp for the mineral plate, the standard clamp holders and the clamp holder base, in which the clamps, with a maximum of four and a minimum of two according to the needs, are introduced into the channels of the standard clamp holder, individually moving horizontally in order to adjust to the position of the plate. In its second variant (three-dimensional façade), the three-dimensional clamps for a composite plate or mineral plate, the clamp holder ball joint and the clamp holder base are used, achieving, with a maximum of four and a minimum of two clamps according to the needs, together with the clamp holder ball joint, a total of four movement axes. Both variants have the clamp holder base in common, which is provided with clipping teeth for inserting the complete clamping assembly in the front track of the vertical load-bearing structure, being able to move vertically in its two variants, adjusting to the height of the plate, and definitively being fixed to the vertical load-bearing structure with a screw.
A broader idea of the features of the invention will be provided below making reference to the sheet of drawings etc.

Description of a Preferred Embodiment of the Invention

The description is focused on the corresponding illustration of the representations of the invention, based on the following:
The U-shaped work anchoring base (1) (Figure 1) is installed directly on the work and can be assembled in three different ways according to the requirements of the work, either it is assembled by means of two screws or plugs which are housed in the boreholes (8) located in the vertical plane (13) of the bottom of the U, or two extended tabs (9) are used, which tabs are coplanar with the wall of the work, for fixing it with screws or plugs by means of the boreholes (12) provided for such purpose, or extending the two flanges (10) located in the vertical plane (13) of the bottom of the U in order to be able to install it by inserting it in grooved bricks.
The positioning latch (2) of Figure 2, which is used for a pre-installation of the vertical load-bearing structure (3) on the already installed anchoring base (1), has a T-shaped catch (15) which enters, by rotating it 90°, in the vertical tracks (21) of the load-bearing structure (3) (Figure 3) and which is slid to the anchoring base (1) in which, by pressing on the plane (18), its tenon (20) provided with teeth (16) is inserted in the lips (23) of the track (21) through the eyelet (11) of the anchoring base (1), placing the plane (19) against the side wings (14) of the anchoring base (1) and leaving the pre-installed load-bearing structure (3). The eyelet (11) of the anchoring base (1) allows the load-bearing structure (3) to move perpendicularly to the vertical plane of the work in order to achieve the plumbing of the latter, finally being firmly fixed by a screw (47) (Figure 4) which is housed and guided in the borehole (17) of the latch (2) shown in Figure 2. The load-bearing structure (3) has an insulating material (4) between the two tracks (21) in its rear part. This system for fixing the load-bearing structure (3) allows installing more anchoring bases (1) as the work progresses.
The standard clamp (5) (Figure 5) for a composite material cladding plate (42) (Figure 11) has a plane (24) with two lips (38) projecting above the tongues (26) in order to be introduced in a vertical position in the groove (37) and in a horizontal position in the two grooves (29) of the standard clamp holder (6) (Figure 7) allowing horizontal movement in both cases in order to find the perfect coupling of the composite material cladding plate (42) provided with grooves (43) which are clipped in the teeth (27) (Figure 11). The elliptical segment (25) joining the two tongues (26) together acts as a spring and keeps the composite material cladding plate (42) pressed between the two tongues (26).
The standard clamp (41) (Figure 6) for a mineral material cladding plate (50) (Figure 12) has a plane (24) with two lips (38) projecting above the tongues (48) in order to be introduced in a vertical position in the groove (37) of the standard clamp holder (6) (Figure 7) allowing horizontal movement in order to find the perfect coupling of the mineral material cladding plate (50) provided with grooves (51) which are clipped in the teeth (40) (Figure 12). The rib (57) joining the two tongues (48) together acts as a spring and keeps the mineral material cladding plate (50) pressed between the two tongues (48).
The assembly of the standard clamp holder (6) with the standard clamps (5) or with the standard clamps (41) are inserted in the clamp holder base (7) (Figure 8), as shown respectively in Figures 9 and 10, placing the plane (32) of the clamp holder base (7) against plane (28) and between the stops (39) of the standard clamp holder (6) with the clipping of the teeth (49), leaving the through boreholes (34) of the standard clamp holder (6) and (33) of the clamp holder base (7) aligned. The complete system of standard clamp (5) or standard clamp (41), clamp holder (6) and clamp holder base (7) of Figures 9 and 10 respectively is clipped or inserted in the assembled load-bearing structure (3) as shown in Figure 11, snapping the central rib (30) provided with two teeth (31) of the clamp holder base (7) into the track (22) of the load-bearing structure (3) which is inserted in addition to guided between the edges (35) of the clamp holder base (7) allowing a longitudinal movement of the assembly of Figure 9 or 10 within the track (22) of the load-bearing structure (3) in order to adjust to the height of the cladding plate. Once in position, a screw inserted into the aligned boreholes (34) of the standard clamp holder and (33) of the clamp holder base (7) leaves the system firmly joined.
The clamp holder base (7) is provided with two wings (55), which may or may not bend, ending with a three-toothed part (56) in order to secure insulating panels within the ventilated façade.
The three-dimensional clamp (45) (Figure 13) for a composite material cladding plate (42) and the three-dimensional clamp (46) (Figure 14) for a mineral material cladding plate (50) have in their rear part a perpendicular arm (52) with a branch segment (53) at the other end in order to be introduced into the ball joint (54) of the three-dimensional clamp holder (44) (Figures 13 and 14) allowing movement along two axes for the perfect coupling of the cladding plates.
Having suitably described the nature of the invention, it is hereby stated for the purposes thereof that it is etc...
