Abstract

Use: for roofing for fastening flexible panels in awning structures, film and glass greenhouses, when creating waterproofing screens. SUMMARY OF THE INVENTION The device comprises a profile that encloses the side edges of flexible polymeric panels from the side walls and the partitions separating them with fixing projections and a scattering element. The profile is made up of a T-shaped part and paired L-shaped parts, having rectangular and L-shaped limbs arranged perpendicular to the flanges, forming partitions. The walls and shelves of L-shaped parts relative to the wall and shelves of the T-shaped part are placed parallel and symmetrically to each other. Moreover, their shelves are directed to one side and the edges of polymeric panels are placed between them. 1 hp f-ly, 2 ill. with s

Description

The invention relates to the field of construction and can be used in the construction of polymer chips, in tent structures, in film and glass greenhouses, in the creation of waterproofing screens.

A fastener device for flexible panels that are overlapped on a rigid circular rod with an open covering profile formed by two walls that are connected by a flexible partition is known.

The closest technical solution is a device for fastening flexible panels on a circular bearing element on which overlapped are side edges of the joined polymeric panels, which are pressed against the supporting element by the upper and lower side walls of the enclosing profile. The upper and lower walls of the enclosing profile are connected by a rotation-permitting partition dividing the side walls into enveloping and spacer parts, with fixing and spacer parts on the latter, with fixing protrusions on the latter defining the position of the riving element creating tension in the device.

The disadvantage of this device is the impossibility of attaching thick-walled panels, since they experience significant bending stresses and cracks at the points of bending.

The aim of the invention is to expand the field of use by allowing the ends of thick-walled panels to be joined.

about

The device for fastening the side edges of the two polymeric panels 1 and 2 includes a composite profile from the T-shaped part 3 and the paired l-shaped parts 4 and 5 and the two propping elements 6 and 7. The lateral edges of the panels 1 and 2 are clamped between the upper clamping lugs 8 and 9 formed on the shelf 10 of the L-shaped part 4 and the lower pinching protrusions 11 and 12 formed on the shelf 13 of the T-shaped part 3. The upper projections 8 and 9 are displaced relative to the lower projections 11 and 12 by about half a step between them. Two riving elements 6 and 7 are located on both sides (symmetrically) from the vertical wall 14 of the T-shaped part 3. On the outer side, the wedging elements of 6 m 7 are tucked in by the walls 15 and 16 of the L-shaped parts 4 and 5. In the upper part, the wedging elements 6 and 7 are limited by retaining protrusions 17, 18, 19 and 20, and in the lower part by retaining protrusions 21, 22, 23 and 24, the T-shaped part 3 is connected to the L-shaped parts 4 and 5 detachably, and on the L-shaped parts perpendicular to its shelves are formed by L-shaped bends 25, and on the T-shaped part are L-shaped 26 and straight: ol s 27 folds.

A device for joining the side edges of two polymeric panels operates as follows.

Assembled one T-shaped 3 and two L-shaped 4 and 5 parts. The L-shaped part is installed with a slope so that the bend 25 is at the entrance to the bend 27 and the locking protrusions 17, 18 or 19, 20 are at the minimum distance. Then by vertical pressing on the L-shaped part 4, the limb 25 enters in off-27 (Fig. 2).

At maximum opening of the gap between the shelves 10 and 13 T-shaped 3 and G-shaped 4 parts, the side edge of the panel 1 is inserted into the gap and clamped by inserting the spacing element 6 into the gap between the T-shaped 3 and G- figurative 4 parts up

stop element 6 in the locking protrusions 21 and 22.

With a maximum opening of the gap between the L-shaped 3 and L-shaped 5 parts

the side edge of the panel 2 is inserted into the gap and pinched by inserting the propping element 7 into the gap between the T-shaped 3 and the L-shaped 5 parts until the element 7 stops

locking protrusions 23 and 24.

In comparison with the known solution, this device for joining polymeric panels has the following technical and economic advantages:

the possibility of joining thick-walled panels, as well as rigid sheets (e.g. glass); kinks and cracks in the panels are eliminated, which greatly increases the reliability of the joint.
