Description

This invention relates to a fastening device for plate flaps with several rotary plates that are mounted on the pins, and pins located on one side of the plate flap, mounted on a carrier rail.

At present, lamellar flaps are known, in which several plates arranged parallel to each other are fastened and rotate on pins. Trunnions are placed on a common carrier rail, which, for attachment to the building, is screwed to a rack profile or to a facade element for connection to the facade. With such a constructive solution, a relatively large distance is formed between two plate flaps, which degrades the appearance of the flaps and complicates their masking. The plates of two adjacent flaps can be mounted on a common carrier rail, but this solution has the disadvantage that it is not possible to manufacture such plate flaps in advance at the factory. Equipping the valves with plates at the construction site is a significant drawback.

Therefore, the objective of this invention is to provide a fastening device for plate flaps of the above construction. In the case of using such flaps, they can be mounted on a rack in finished form, two adjacent flaps can be attached to the supporting structure in a very simple way.

This problem is solved through the mounting device for plate valves with signs according to claim 1 of the claims.

If the carrier rail of one plate flap and the carrier rail of the second plate flap are attached to a transition rack mounted on the building, then both flaps can be pre-fabricated at the factory, and in this design, the individual plates are held on the carrier rail with trunnions. The installation of such pre-fabricated plate flaps can be done in a very simple way, securing the carrier rails on the transition rack.

Fastening can be carried out with the help of screw connections, riveting, connecting with a latch and other connecting elements. Moreover, to simplify the installation of plate flaps, the transitional rack can be pre-installed on the building. As a transitional rack, you can use any building element that has a surface parallel to the corresponding plane of the building, for example, T-bar, channel or hollow (in particular, rectangular) profile, as well as other profiles.

In accordance with the preferred structural form of the bearing rails, both the first and second plate flaps are mounted on the transitional rack from the front side.

This simplifies installation, since the front side is usually more accessible. In this case, the carrier rails in the cross section are preferably L-shaped, with holes for the pins on one of the sides of the rail, and holes for fastening to the transition stand on the other side. At the same time, to facilitate the positioning of the support rails, centering elements may be provided at the transition rack and carrier rails for positioning the support rails relative to the transition rack.

In order to ensure high rigidity of the fixing device, located next to the support rails on the side opposite to the transition stand, preferably should be connected to each other by means of a bracket. Thanks to this design, both carrier rails, a transitional strut and a bracket form a single whole in the form of a hollow profile consisting of several parts. To facilitate the mounting bracket, it must be clamped on the carrier rails.

It is preferable to provide an enclosure attached to them in order to place adjacent plate flaps after installation fit into the building, on the bracket and (or) carrier rails.

According to another embodiment of the invention, the transitional stand must have an I-shaped section into which the facade element can be inserted for connection with the facade, and a bearing surface with slots for screws is provided on the opposite side of the transitional rack for fastening the support rails on this surface.

The following is a detailed description of the invention in one example of its constructive implementation. The description is accompanied by references to the accompanying drawings. The drawings depict the following:

The plates 2 can rotate on the pins 4, and the pins 4 pass through the carrier rail 3. The plates 2 consist of an aluminum profile, made by hot pressing, from the ends they are covered with lids 5 and 8. On the lid 5 a bracket 6 is molded, to which the thrust 7 is attached, designed to rotate the plates 2. The lamella flap 1 can be prefabricated in a workshop in as a unified node.

FIG. 1A shows a bearing support for plates 2, made in the form of a fixed bearing. The trunnion 4 is attached to the carrier rail 3, and a liner 9 is provided around the trunnion 4. The liner 9 has flanges 10 that are adjacent to the carrier rail 3. In the region of the flange, the trunnion 4 has a ledge, thanks to which the liner 9 on one side fits to the ledge of the axle 4 and, on the other hand, to the retaining ring 11, due to which the stiffness of the axle in the axial direction is ensured.

FIG. 1B shows the opposite bearing support for plate 2. Support for pin 4 is an insert 9, which is fixed to carrier rail 3 by means of shoulders 10. Pin 4 is held on the carrier rail by means of a locking ring so that the pin cannot fall out of the rail. the retaining ring 11 and the insert 9 provide a gap 12. Due to this gap, the pin 4 can be moved in the insert 9 within certain limits, for example, in order to compensate for thermal expansion.

On the carrier rail 3, a groove 14 and a hole 13 are provided, which are used to fasten the carrier rails 3 on the transitional rack 20.

As shown in FIG. 2 and 3, two adjacent plate flaps 1 with plates 2 with the help of a fixing device mounted on the facade element 25, which is mounted on the building. For this, an adapter post 20 is provided, in which there are jacks 21 for screws 28. On the side facing the facade element 25, the adapter stand 20 is ϋ-shaped, and on this side the stand contains elements 23 made in the form of a hollow profile. Transition rack 20 in the present embodiment, the design is attached to the front element 25 with a few mounting bolts 24, and the mounting bolts 24 pass through both elements 23. In the transition rack 20 has a cavity 22 on which shaped parts are formed. These parts can be used, for example, for angle or T-shaped connection, for cable laying and other purposes.

The carrier rails 3 are generally shaped, each rail has a face 50, on which openings are provided for insertion of pins 4, and a face 51, on which holes 13 are provided for fastening the carrier rails 3 to the transitional rack 20. At the same time, the face 51 lies on the support the surface 26 of the transitional stand, on which the protrusions 27 are provided. These protrusions 27 fit into the groove 14, which is in face 51, they are used for centering and positioning the carrier rail 3. The carrier rail 3 is fixed to the transitional pole 20 with several screws 28, that pass through face 51 and are held in slots 21.

From the side opposite to the transition strut 20, the carrier rails 3 are fastened to each other with the help of the brace 30. Under the action of wind or other mechanical loads, the carrier rails 3 made of metal can be slightly deformed. In order to provide high rigidity, a bracket 30 is provided, thanks to which the carrier rails 3, the transition strut 20 and the bracket 30 form one unit. For this, the bracket 30 has two protrusions 31, which fit into the corresponding grooves 32 on the edge 50 of the carrier rail 3. The bracket 30 is fastened by means of a screw 36 that passes through the bracket 30. A screw 36 passes between the carrier bars through two structural elements 34 and 35 of the bracket 30. The structural element 34 is attached to the outer part of the bracket with the help of the U-shaped slopes 30. When the screw 36 is rotated, the slopes 33 move, depending on the direction of rotation of the screw, diagonally outward or inward until the connecting step between the slopes 33 It does not fit to the stop 37 on the edge 50 of the carrier rail 3. Bracket 30 sets the distance between the two faces 50 of the carrier rails 3, for maintenance it can be removed, for which you need to unscrew the screw 36. Preferably, the length of the bracket 30 should be 40 mm, it should be inserted between bearing rails 3 only in some areas. Bracket 30 may also be solid.

On the edge 50 of the carrier rail 3 there is a locking protrusion 38, which is used as a fixing device when mounting the casing 40 from the front side. The shell 40, which preferably should be made of metal, it is enough to hook on the locking protrusions 38, while the locking protrusions 41 engage on the locking protrusions 38, and the shell 40 is securely fixed. The bracket 30 allows you to very accurately set the distance between the two faces of the 50 carrier rails 3.

FIG. 4 shows a cross-section of the carrier rail 3. In the face 50 of the carrier rail 3 there is a groove 32, which is designed so that it includes a protrusion 31 of the bracket 30 and an outward protrusion 38 facing outward. In the inner side, an emphasis 37 is formed, to which U -shaped slots 33 brackets 30.
