Holder for fastening electrical pipes in ducts in walls.

Field of application of the invention

This invention relates to a holder as a fastener for fastening electric pipes in ducts in walls and walls.

When carrying out electrical and installation work in buildings, it is common to insert electrical pipes for cables and wires into cut-outs or molded ducts in walls and walls. When the electric pipe with or without cables is inserted into a duct, it must be fastened and held in place so as not to overturn. Later, the duct is closed by walling or covered with sheets.

Prior art

Fastening of electric pipes in ducts in walls and walls is carried out according to the prior art by punching a few nails into the wall on both sides of the electric pipe. The protruding parts of the seams lie in over the electric pipe and form a cross. Thus, the electric pipe is attached to the wall at the bottom of the duct. The seams are punched into the wall in pairs at appropriate and appropriate distances as needed.

Figure 1 shows attachment of electric pipe 3 according to the prior art by means of stitch 4. The seams 4 are inserted into the bottom of the channel 1. Channel 1 is located in wall 2.

The technical issue to be read

The prior art of fastening electrician tubes with pairs of intersecting nails is somewhat inappropriate in practical use. It is time consuming. Often, the seams are difficult to strike because of stones in the wall, which increases the time consumed.

When thinking about major construction contracts, the time spent seaming electric pipes can become considerable and costly. It requires the use of tools to punch the seams into the wall.

Therefore, there is a need to have a fastener or holder for the fitting of electrician pipes, so that the work of carrying out electrical installations can be made more efficient and thereby get better economy in the installation work.

The new technique

The new feature in the holder for attaching electric pipes is that a holder is made in, for example, a stainless steel spring or other material such as plastic, preferably of circular cross section. The holder is shaped so that it encloses the electric pipe and so the two protruding and tapered legs of the holder can get caught in bumps on the sides of the duct. Thus, a good fastening of the electric pipe in the duct in the wall is achieved.

The technical impact

By using the holder described above for fixing electric pipes in wall ducts, it is achieved that electric pipes can be easily and quickly mounted and fastened in a workflow in ducts in walls, thus saving time and money while the installation takes place without the use of tool.

The holder and a preferred advantageous embodiment are explained in detail below in reference to the figures.

List of Figures

Figure 1 shows a duct with electric pipes attached to the bottom of the duct with nails.

Figure 2 shows the holder.

Figure 3 shows duct with electric pipe attached with holder.

Embodiments

Figure 2 shows holder 5 in a preferred embodiment. The holder 5 is made of stainless spring steel with a circular cross section of d = 2 mm, for example. Other cross sections and dimensions can be used. Holder 5 is made in a bending tool and it is cut off at the ends of the protruding legs at an angle v = 45 °, thereby producing a tip which ensures good attachment to the sides of the channel 1.

Holder 5 is made in the shown version with diameter D corresponding to outer diameter of electrician pipe 3, width of BH, corresponding to standard width Br of channel 1, but about 10 mm wider, so that 5 clamps hold against the 1 sides of the channel in wall 2, thereby holding retainer 2 when mounted in channel 1. Otherwise, the starting material has a diameter of d = 2 mm, bending radius R, width of width 1, height H, cutting angle v = 45 ° angle between the legs of holder 5 after bending at bending radius R, w = 180 - 2v, corresponding to 90 ° in this example.

Holder 5 can be fitted to the electric tube 3 by pushing the electric tube 3 through the width 5 of the holder 5, 1.

Claims (2)

3 DK 2007 00023 U3 1. Electricity pipes are inserted into ducts in the walls of buildings where they must be fastened with fasteners so as not to knock out before the duct is closed, which may be a holder 5, Figure 2, which is new in that the holder is made of the example stainless steel wire or other material such as plastic of diameter d and aperture for electric pipe 3 of diameter D having two tapered legs spanning the width, BH, greater than the width, Bk, of the channel 1 of the wall 2 and the legs extending from the aperture to the electric tube (3) at radius R at an angle w = 180 ° - 2v, so as to form a gap of width, 1, and so that the holder 5 obtains a height H.
