DEVICE FOR ATTACHING LINE WIRE PILLARS BETWEEN FLOOR AND CEILING

The invention relates to a device for fastening the fastening columns of a line wire used in guiding masonry between a floor and a ceiling when masonry of straight walls or the like.

In buildings in apartment buildings, the laying of the line is usually done by attaching the lin-5 footboards one end to the floor and the other to the ceiling, after which the interest distribution is marked with a pen. Usually the floor and ceiling are concrete, so fixing requires a nail gun or drill. One of the disadvantages of such an attachment is poor occupational safety. It is often necessary to reach high while standing on a ladder and use both hands to nail or drill. Sometimes it is impossible to place the ladder firmly and you will be in danger. Using auxiliary labor can improve this, but it is expensive In addition, lines made of boards waste supplies, nails, and boards because they have to be made over and over again. It is also difficult to dismantle the lines made of boards.

15 The line poles are also made of metal, making them detachable and reusable. Swiss Patent Publication 475,455 discloses such a column. It locks in place so that the spring presses its ends against the ceiling and floor. Such a fastening cannot be considered sturdy and there is a risk that it will move out of place during masonry. Another corresponding column 20 is disclosed in U.S. Pat. No. 3,096,588. Its lower end is secured by a plate under the lower corner bar and the upper end is secured to a wooden structure by a nailed support. However, removing support under masonry after work is difficult. U.S. Pat. No. 2,761,214 discloses a single-pillar ta-25 Ιση external column to be attached to an outer wall, which is attached by means of compression screws. This model is not easy to use in the interior masonry of an apartment building.

2,83987 The present invention overcomes the disadvantages of the known structures and its characteristic features are set out in claim 1.

An embodiment of the invention is illustrated below by means of figures. Figure 1 shows a device according to the invention mounted in connection with a masonry wall.

Figure 2 shows a side view of a line column according to the invention.

Figure 1 shows how the posts 3 are placed next to the wall 1 to be built so that a wire 2 can be tensioned between them. The wire is attached to sleeves 5 which can be moved along the posts 3. When the wires io are lifted at intervals according to the scale 4 and the bricks are laid under the guidance of the wires, a straight, evenly laid wall is obtained.

Figure 2 shows a fastening method according to the invention, by means of which the posts 3 are fastened between the floor and the ceiling. The column 3 consists of an outlet pipe 6 and an inner pipe 7 sliding inside it. The pipes can be locked to each other with a screw tightening device 8. At the lower end of the post there is an adjusting screw 9, by turning which the position of the lowest row of bricks can be adjusted to a suitable height. At the upper end of the post there is a fixed, horizontal sleeve 1¾ through which a tensioning arm 11 passes. The tensioning arm has a sliding tensioning sleeve 12, the upper surface of which is made protruding and flat to correspond to the surface of the roof 13.

Attach the post as follows. The clamping arm 11 is placed on the sleeve 10 approximately in the position shown in the figure. The clamping sleeve 12 is placed at the very end of the arm 11. The starting height of the masonry is adjusted by the adjusting screw 9 and then the inner pipe is lifted in the outer pipe so that the free end 14 of the clamping arm 25 and the clamping sleeve 12 hit the ceiling. The inner tube is then tightened to the outer tube by a clamp 8. When the clamping sleeve 12 is now moved towards the articulation point formed by the sleeve 10 while the arm 11 is bent downwards, the arm end 14 corresponds to the ceiling and the lever effect pushes the column 3 downwards. A sturdy three-point attachment is formed when the screw 9, the end 14 of the arm 3 83987 and the clamping sleeve 12 are pressed against the floor and ceiling.

The fastening made in this way is easy to perform, it is sturdy and non-torsional, and it is also easy to remove. The post can be moved quickly and safely to a new destination without wasting consumables.
