Description

Technical field

The utility model relates to the field of construction, namely, devices for fastening cladding elements at the transition between two surfaces (for example, floor and wall) and can be used for hidden fastening of skirting boards, decorative profiles, claddings and other similar elements having fixing grooves.

State of the art

The closest analogue of the utility model to the totality of structural elements is the fastener for cladding elements disclosed in Swiss application CH694891, 08/31/2005. The device is made in the form of an angular profile of sheet metal. The profile has a wall and a base placed at right angles. A fixing hole is made in the wall. The device also has an upper mounting protrusion for placement in the upper mounting groove of the facing element, formed by a bend of the upper end of the wall and including a part protruding inward from the wall, passing into the upper (-shaped (arch-shaped) tongue, which extends from the base. In addition, the device also has a lower protrusion designed for laying cables in it. The specified lower protrusion is formed by bending the end of the base along a curved line in the direction of the wall.

The disadvantage of the closest analogue is the relatively low rigidity of the mount. This is due to the fact that the lower protrusion does not provide retention of the facing element, which is attached only to the upper mounting protrusion.

Utility Model Disclosure

The objective of the claimed utility model is to eliminate the disadvantages of the analogue and to develop a device for reliable fastening of the facing element, including large widths.

The technical result of the utility model is to increase the fastening of the facing element.

The specified technical result is achieved due to the fact that the fastening device of the facing element at the interface of two surfaces is made in the form of an angular profile of sheet metal material containing a base, a wall provided with a fixing hole and an upper mounting protrusion for placement in the upper mounting groove of the facing element formed bending the upper end of the wall. The upper mounting protrusion includes a part protruding inward from the wall, passing into the upper arcuate tongue, which extends in the direction from the base. The device also includes a lower mounting protrusion for placement in the lower mounting groove of the facing element. The specified protrusion includes a lower tongue formed by bending the end of the base along a curved line in the direction of the wall. In this case, the end part of the lower tongue is bent in the opposite direction.

In addition, according to private options for implementing the utility model:

- the ratio of the height of the lower tongue to the height of the upper tongue is from 1.5 to 3,

- the ratio of the distance between the wall and the upper tongue to the width of the upper tongue is from 2 to 3,

- the angle between the plane of the lower tongue and the plane of the base is 45-65 °,

- in the area of the mounting hole of the wall is made flanging,

- the wall has a stiffener.

- a cutout is made in the central part of the lower mounting protrusion, which forms an additional tongue, bent into the plane of the base.

In contrast to the closest analogue, the device under consideration has a lower mounting protrusion of a special configuration, which provides pressing of the lower part of the cladding due to the elastic properties of the sheet material and increases the overall rigidity of the structure.

The described special cases of the implementation of the design are also aimed at increasing the rigidity of the connection. However, they are not the only possible options for executing a utility model. It should be noted that the technical result of the utility model will be achieved without the use of these additional features.

Utility Model Implementation

The claimed mounting device (Fig. 1,2) is made in the form of an angular profile of sheet metal material, in particular spring steel.

The specified profile includes placed at an angle (preferably at a right angle) wall (1) and the base (2). The wall (1) is intended for fastening the claimed device to a vertical surface (3), in particular to the wall, when installing the facing element (4) (see Fig. 6). To do this, one or more mounting holes (5) are provided in the wall (1) to place fasteners (6) in it, for example, self-tapping screws. To increase the rigidity and reliability of fastening the device around the hole (5), a flange (7) can be made in the form of a bulge directed inward to the part (see Fig. 1.2). In addition, to increase the rigidity of the fastening connection, the wall, optionally, has a stiffener (18) in the form of an oblong bulge directed inward to the part. (Fig. 1,2).

In the upper part of the device is made of the upper mounting protrusion (8), formed by bending the end of the wall (1) and designed to hold the facing element (4). The upper mounting protrusion (8) consists of the part (9) protruding inward (sideways with respect to the part) and the upper Ո -shaped (arch-shaped) tongue (10), which is a continuation of the part (9) and extending in the direction from the base (up). The protruding inward part (9) is preferably oriented perpendicular to the wall, and the upper tongue (10) is parallel to it.

 The upper tongue (10) is designed to be placed in the upper mounting groove (11), which is a continuation of the cavity made in the facing element (4). The upper tongue (10) may extend from part (9) in the direction from the wall (see Fig. 5a) or towards the wall with the formation of an open loop (see Fig. 5b). The width of the tongue (10) preferably coincides with the width of the groove (11).

In a preferred embodiment of the utility model, the distance (S) between the wall (1) and the upper tongue (10), as well as the width (B) of the upper tongue (10) must satisfy the ratio S / B = 2 - 3. This is due to the optimal rigidity of the upper mounting protrusion for holding the facing element (4). With a ratio of less than 2, the upper tongue (10) may begin to bend when installing the facing element, without providing its support in the vertical plane. With a ratio of more than 3, horizontal stiffness can be significantly reduced.

The base (2) of the fastener is intended for contact with a horizontal surface (12), in particular with the floor. The base (2) is preferably flat.

A lower mounting protrusion (13) is also provided in the lower part of the device for holding the facing element (4) by placing it in the lower mounting groove (14) (see Fig. 5).

The lower mounting protrusion (13) contains one or more lower reeds (15) formed by bending the end of the base along a curved line in the direction of the wall (2). The specified tongue (15) has an end part (16), which is bent in the opposite direction, which is necessary to increase the rigidity of the protrusion and ease of installation of the facing element.

The angle (α) between the plane of the lower tongue (15) and the plane of the base (2) (bending angle of the tongue) is preferably 45-65 °. This is due to the presence of the mounting element (4) of the mounting groove (14) in which the tongue is placed. If the angle value is less than 45 °, it is necessary to significantly increase the width of the specified groove (14), which is not always possible, or to reduce the length of the tongue (15), which will lead to a decrease in spring properties when installing the cladding. If the angle value is more than 65 °, the tongue (15) will not exert sufficient pressure on the facing element (4) for its reliable retention.

In a preferred embodiment of the utility model, the height (H1) of the lower tongue (15) and the height (length) (H2) of the upper tongue (10) satisfy the condition: H1 / H2 = 1.5-3. This is due to the difference in the configuration of the arcuate upper tongue (10), designed to support the upper part of the facing element, and the curved lower tongue (15), which provides the lower part of the facing element against the wall (3). If the indicated ratio is less than 1.5 (the upper tongue (10) will be slightly smaller, equal to or greater than the lower tongue (14)), the rigidity of the upper part of the joint will be significantly less than in the lower part, which can lead to the formation of a gap between the upper part cladding and wall and, as a consequence, lowering the overall rigidity of the structure. On the other hand, when the ratio of the parameters is more than 3, the opposite situation may arise when the lower part of the joint will be much more rigid than the upper one, and the lower tongue will not be able to provide sufficient pressing force of the cladding. As a result, overall structural rigidity may also decrease.

A cutout can be made in the central part of the lower mounting protrusion (13), forming an additional tongue (17), bent in the direction from the wall (1) to the plane of the base (2). The specified additional tab (17) serves as an additional support element for the base and may have a different shape. In particular, said tongue (17) can provide separation of the lower mounting protrusion with the formation of two lower tongues (15).

The device can be obtained by means known to the specialist in sheet metal processing technology. In particular, cutting of a steel tape, subsequent cutting of the tape into billets and their bending can be applied.

The fastening device can be used to install various cladding elements (4) at the interface between two surfaces, for example, a vertical surface (3) of a wall and a horizontal surface (12) of a floor (see Fig. 6). To do this, the mounting device is installed on the floor in the place of its interface with the wall. The wall (2) is attached to the horizontal surface (3) of the wall through the holes (5) by means of fasteners (6). Next, the facing element (4) is installed vertically, leading the upper mounting protrusion through the cavity with the upper mounting groove (11) and placing the upper (10) and lower (15) tabs in the upper (11) and lower (14) mounting grooves, respectively. In this case, the upper part of the lining is fixed with the upper tongue (10), as well as the elastic deformation of the lower tongue (15) in the direction from the wall (2), which creates a clamping force of the element in the opposite direction and ensures reliable retention of the element (4) of the lining.

Despite the fact that the operation of the device is demonstrated by the example of fastening a facing element at the junction of perpendicular floor and ceiling surfaces, it can also be used to install facing elements on other types of surfaces, the angle between which can be different from 90 °.
