Abstract

DEVICE FOR SUSPENDING SUSPENDED CEILING on the bus. St. No. 514940, characterized in that, in order to reduce the material consumption and simplify the manufacture and adjustment of the suspension, the frame has holes, the distance between the centers of which is equal to the distance between the centers of the wide and narrow parts of the figured hole of the yoke made in the form of a flat plate, and The restrictor is made in the form of a round rod with an emphasis on the upper end.

Description

The invention relates to construction and is used to hang light structures that require vertical adjustment, for example, suspended ceilings (impassable), air ducts, small-diameter pipelines, cables, lamps, chandeliers, and the like.

According to the main author. St. No. 514940, a device for hanging a suspended ceiling is known, including its movable yoke with holes covering the profile of the supporting frame, adjustable suspension skipped in the hole of the yoke, figured with variable width, in the narrow part of which a narrowed suspension section is inserted, In a wide - mounted on the suspension limiter 1.

The disadvantages of the known suspension device are the eccentric application of the load on the clamp and the possibility of its rotation on the frame in case of an inaccurate manufacture of the clamp in height; relatively high metal consumption for the clamp; the complexity of the device limiter. The purpose of the invention is to reduce material consumption and simplify the manufacture and adjustment of the suspension.

The goal is achieved by the fact that in the device for hanging suspended ceilings the frame has holes, the distance between the centers of which is equal to the distance between the centers of the wide and narrow parts of the shaped hole of the yoke, made in the form of a flat plate, and the limiter is made in the form of a round rod with a stop at the top end.

FIG. 1 shows the device, a general view; in fig. 2 - clamp in the form of a flat plate; in fig. 3 is a section A-A in FIG. one; in fig. 4, 5 and 6 illustrate the sequence of installation and adjustment of the device; in fig. 7 is a section BB in FIG. 6; in fig. 8 - device with a frame from two parts, general view; in fig. 9 - device with perforated channel frame, general view.

The device contains a supporting frame 1, having at least two round or oval holes 2 or an opening in the form of a longitudinal slit 3 along the entire length, a rod suspension 4 of a periodic profile with a hook 5 at the lower end, a clamp 6 in the form of a plate with a figured opening 7 of variable width , limiter 8 in the form of a round rod with an emphasis 9 on the upper end. The distance E between the paired holes 2 is equal to the distance between the centers of the width A and the narrow B parts of the shaped hole 7.

The installation and adjustment of the device (Fig. 1) is as follows. The rod suspension 4 of the periodic profile is inserted into one of the holes 2 of the frame 1, on which the plate 6 is put on top of it with a wide part A of the figured hole 7.

Suspension 4 is manually adjustable vertically, freely passing through openings 2 to A. Usually, adjustment of suspension 4 is done when there is no payload on its hook.

Then the plate 6 is shifted to the left, while the suspension 4 with its narrowed cross section formed by two opposite holes (recesses) is inserted into the narrow part B of the figured hole 7, and its wide part A is aligned with the second pair hole 2 of the frame 1 where the stop is inserted 8 with an abutment 9 at the upper end, and thereby securely securing and fixing in a certain position of the suspension 4 vertically and horizontally.

Limiter 8 prevents the suspension exit 4 from the narrow part B in the direction of the wide part A of the shaped hole 7. The stop of the limiter 8 prevents it from slipping into the hole 2 or the wide part A.

The stop 9 can be structurally made in the form of a straight limb or head (such as "nail," rivet).

The installation and adjustment of the device with a longitudinal slit 8 is carried out as follows.

The plate 6 is superimposed on the top of the cage Qa 1. Suspension 4 is inserted through the slit 3 into the widest part A of the figure hole 7, the suspension 4 is adjusted vertically, then the suspension 4 and the plate 6 are displaced relative to one another along the frame so that the suspension 4 by its narrowed section enters a narrow part B of figured aperture 7, and a limiter 8 is introduced into its wide part A, the diameter of which is larger than width B.

This device variant has several advantages: the length of the figured hole 7 is not

0 depends on the distance between the centers of the paired holes 2, and is determined only by the diameters of the suspension 4 and the restrictor 8; the device can move freely in an assembled position along frame 1, i.e. be adjusted and horizontally that

5 is very important for the suspension of the suspended ceiling; payload through suspension 4 is applied without eccentricity with respect to frame 1 and anchor suspension 10.

Wide part A shaped hole 7

0 is generally round with a diameter greater than the diameter of the suspension 4. For example, for a suspension with a diameter D of 5 mm, diameter A will be equal to 6 mm.

The narrow part of the shaped hole 7 should be made in its width

5 with an accuracy not lower than the fourth class, since on the face of this hole in the top are the protrusions formed by two opposite dents (recesses) of the narrowed section of the suspension 4, having a periodic profile.

Adjustable rod suspension 4 is a reinforcement of a periodic profile according to GOST 8480-68, which is widely used to reinforce reinforced concrete structures.
