Description

FIELD OF THE INVENTION

The invention relates to a header, the aid of which secures the preaetl to the wall 111 plate 1 falls within the field of construction joinery 1 accessories. According to the International Patent Classification (IPC), the invention is classified according to the International Patent Classification (ILC), which is labeled 1 denoted by the class I F 16 B 13/14 1 F 16 B 13/04.

Technically penetrated

Technically, the problem that needs to be solved by finding "consists of the following": how to get a header from a high-quality aater that can be glued to both the Hollow walls and 1 in the punia zldovlaa?

The state of the art

A number of header constructions are known for grouting walls 1 for solid walls. As a rule, such a header has more than two shoulders. Because of the rigid torsional rigidity of these rails, twisting of the screws causes the shoulder 1 to overlap. In order to achieve a flattening, generally a very soft material is required for the header. Due to the swollen aater, the bolt even though it is screwed into the header, with no major tightening force. When applying the header to the punia zldovlaa, due to the swollen aater, no satisfactory fixations can be made here.

A description of the solution to a technical problem

The technical problem is solved by finding this way, what is the contour crosswise? before cutting both shoulders in the middle area, the el 1 dog is operating. which in the direction of the body 1 of the header head goes in a circle, What are both opposite shoulder surfaces apart from each other, whose luminous aperture corresponds to the difference between the large 1 oa * log diameter of the ellipse, 1 One hundred holes in the ramenloa in continuation of the longitudinal opening of the header head grooves.

The use of a "header according to the invention for attachment to the panels, sutures of the like, will result in a twisting of the screw in the longitudinal opening of the body, due to the radial bending, of both shoulders axially from the end. In the case, a backrest is created on the back of the board and is tightened by tightening a particular object. Due to the elllpical shape of the shoulder, a flexing force in the radial direction is obtained by operating the force component, which accelerates the bending.

If the header is used in a full wall, it is inserted in the booth, the diameter of which corresponds to the outer diameter of the body or. header heads. Elliptical? The shape of the threads The ramenlaa whiplash is pinched in the diameter of the bore, which causes the surface of the slits to reach the middle area of the shoulder. This narrowing of the slit leads to the expulsion of the material into the buSotlnl when screwing in the screw. The longitudinal grooves, which extend into the crevices of the two scaffolds, form a screw channel, which is used to guide it 1 It makes it easier to cut the screw into the material of which the header is made. This screw channel ensures that the tip of the screw will be guided in the longitudinal opening of the header body. By narrowing the gap, the header is placed in the full wall in the same way as known, elastic headers designed for solid walls. As the anchorage of the header in panels 1 with hollow walls does not require the creation of folds by rotating the shoulders, eternal hovlm Twisting, welding of the contrails, which is possible if the header is made of high-quality material, whereby the same can be used for solid walls, where they can be achieved high fixture values.

According to a further feature of the invention, a weakening of the cross section is provided in the middle of the shoulder region, primarily in the form of a transverse opening.

These "weakening" of the cross-section, which does not significantly affect the anchoring, will occur when tightening in the circumferential space, a predetermined "sixth outbreak. For this, the forces required are communicated via a screw mounted in the body of the header. · This additional twist point is especially suitable for a genuine header of 1 ps, but a cardboard "board", because in such panels the header of the header knives to cut "1 sano". only craft aooents.

Further improvement of the bending capability of the header is achieved in such a way that the grooves in the area of composition are aligned with the body of the header.

The invention will be explained in greater detail on the Basis of the Exemplary Example shown in the drawing, where:

FIG. 1 shows a header prior to the "invention partially in longitudinal" section 1 in two cross sections, FIG. 2 shows the attachment of the header predaet to the plate 1 of FIG. 3 shows the fixation of the header predaet on a full wall.

In FIG. 1, the header 1 shown consists of a body 2, which is 1 "elongated opening 3 with internal" ribs "4, shoulders 5 extending from the outside of the body 2 1 of the head 6. Ha of the head 6 A flange 7 is constructed to secure the axial tensioning of the header 1 , and for the sake of protection against turning »on the head are provided ribs 8, which stick into the wall or. well 19. The contour of the cross section of the raeena 5 in the central region is an ellipse, which, before the head 6 1 before the body 2, goes in a circle.

The small diameter of the ellipse corresponds approximately to the diameter of the well 19. The shoulders 5 are divided procepoo 9 extending from head 6 to the body 2 of the header 1. The bright opening of the orifice 9 corresponds to the difference of a large 1 "log diameter of the ellipse at the thickening U of the shoulder S, 1 to at most" 10. These shoulders may be pinched to the diameter of the well 19.

This would be provided by the bending of Raaen S in the region of maximum thickening 10, a cross-section weakening is provided in the form of a cross-sectional opening 11, which is in the plane of the gap 9. Further loosening of the cross-section is foreseen in the region of connection of the joint 5 with the body "2 of header 1 This cross-section attenuation is made by two grooves 12, which are directed to the plane of the gap 9. From the longitudinal opening 13 of the head S to the longitudinal opening 3 of the body 2, the grooves 5 open the longitudinal grooves 14, which serve to guide the screw 17.

Table mounting object * 15 to panel 16 «according to FIG. 2 "will screw the screw 17 into the longitudinal opening 3, the body 2 pulled n" back of the panels 16. At the sink, on the sixth bending time, the so-called shoulders 5 radially outwards, 1 collapses. These "a large surface counterbalance 16" is formed on the back of the panel 16, which makes it possible to secure, for example, objects 15t to g and to the cardboard panels 16.

In FIG. 3 shows the anchorage for head 1 in full wall 18. When installing header 1 in bore 19 corresponding to the diameter of the body 2 1 of head 5 of header 1, both shoulders 5 "will be tightened due to their thickening 10, so that the surfaces p are shrunk so that 9 touch in their central «area. From the longitudinal grooves 14, the trimming canal is used to guide the screw 17 until it engages the longitudinal opening 3 of the body 2 of the header 1.
