The invention in the field of construction, namely the elements for connection to a bevel cut profiles window, door and facade frames. Connection element profiles is shaped double dovetail slots and brought into the inner side profiles compound. Connection element profiles made of heat-shrinkable material. In the middle part of the element introduced by the ferromagnetic powder to heat it under the influence of electromagnetic fields generated and locking profiles.

DESCRIPTION OF THE INVENTION

The invention relates to the field of construction and is intended for connecting the profiles, for example for connection to a bevel cut profiles window, door and facade frames.

Known gusset cut to bevel hollow profiles window, door or facade frames. The compound contains angular binder of their regiments in the internal cavity profiles. Between the inner surfaces of the hollow profiles and corner provided a bunch of adhesive mass. Angular bundle is extending along the side surfaces parallel to the longitudinal median plane of the groove, which communicate with a distribution channel for pumping the adhesive mass. Between the side surfaces and the inner surfaces of the restrictive new profiles provided defined remote parts slotted cavity for an adhesive mass filled the grooves [1].

Furthermore, a method that increases the strength of the pipe joints by performing the middle part of the locking element of heat-shrinkable material [2]. Shrink tselnovyazany material is a textile material, impregnated with the binder. It was then blown with steam to a temperature of 90-100 ° C. After curing, one-piece butt joint is formed. When this compound is not the task of concealment tightening profile.

The closest to the proposed technical solution may include up construction to fill the opening in the wall, which comprises abutting wooden parts, one pair of which is provided with mechanical slot facing the cavity to the cavity of the mechanical groove formed on the second butting parts, and placed in the cavities of the key. End tapered grooves made to the interface section details. The key has a decreasing to its longitudinal axis is not less than 0.1 its maximum height mainly - shaped or X-shaped cross section whose height is at least a portion of at least the length of the key corresponding size socket groove. The key is made of a polymer material, preferably based on polyamide, and has longitudinal corrugations [3].

Known designs do not provide sufficient strength and reliability of connections with multiple dynamic effects during operation, the corner joints designs evenly tightened across the length of the joint, and in the assembly process requires a large labor input and the use of special equipment and devices.

The object of the present invention to provide a hidden element connection profiles, increased strength and reliability design, ensuring uniform contraction across the length and thickness of the interface without requiring the use of glue, changing connection assembly speed, and the ability of the technological process at the lowest possible production sites, while ensuring high product quality.

The essence of the proposed technical solutions lies in the fact that the connection profile element is configured in form of double dovetail slots and inserted in the profiles from the inside, it is made of heat-shrinkable material, and in the middle part of the element introduced ferromagnetic powder. When heated, such as by exposure to an electromagnetic field at a middle portion of the profile element compound shrink material element and the compression is hidden, even a strong contraction of the profiles over the entire length of the joint.

The novelty element of the connection profiles taken along the dual dovetail and inserted into the grooves of profiles on the inner side of the compound is that under the influence of electromagnetic field and heating the middle part of the locking element made of heat-shrinkable material inserted therein a ferromagnetic powder, there is a latent having strength and durability, uniform retraction and locking profiles across the length and thickness of the joint, which does not require adhesive connection assembly with a minimum speed.

There was a new set of essential features, namely: there is a hidden and lasting contraction profiles along the entire length of the joint due to the impact of the electromagnetic field generated by the heating and the middle part of the locking member profiles joints made of thermosetting material with the introduced ferromagnetic powder.

Figure 1 - general view of the angular and vertical element connection profiles.

Figure 2 - cross section of the element connection profiles.

The corner joint parts 1 and 2, two connection profiles with a force element 3 is inserted into the cavity formed by the grooves communicating with each other. Connection element profiles 3, in this example a locking key having a cross-section, referred to as "double dovetail" securely locks formed parts 1 and 2 joint. In the middle part of the key, made of heat-shrink material by extruding simultaneously with the formation of the profile of the ferromagnetic powder is introduced. When exposed to the electromagnetic field due to the appearance of the particles of the ferromagnetic powder, eddy currents and energy losses due to magnetization reversal, is heated the middle part of the element connection profiles and contraction profiles along the entire length of the joint. With the connection structure provides strength characteristics for the entire length of the joint, but also eliminates any deformation at the connection, even after a long period of operation. Furthermore, the proposed technical solution is inserted into the key grooves from the inner side structure, thus providing invisibility gusset. The strength of contraction of the connected profiles depends on the number entered in the middle part of the locking tabs of the ferromagnetic powder and the time of exposure to electromagnetic fields.

Connection of profiles may be any angle from acute (a and 6 in Figure 1) to a right (in Figure 1).
