Abstract

The invention is an aid in building non-bearing internal walls. It replaces the wooden posts used in most cases which are vertically erected and wedged between floor and ceiling, in order to render the plumbing of the individual wall layers unnecessary. It can be adapted to the room height and remains standing without attachment. It consists of a base element, as a rule a hollow section, of a displaceable head piece, and if necessary, of a displaceable foot piece. The head piece is elastic and, as a rule, consists of two parts which are connected force-locked to one another by means of a spring element. The base element has movement slots extending longitudinally at both ends. Head and foot piece have mounting means projecting in the transverse direction, by means of which they are detachably connected to the base element through the movement slots. Base element and foot piece have markings for the wall layer heights.

Description

description

Alignment and measuring stick The invention relates to a tool for bricklayers, which is used when laying non-load-bearing interior walls.

Straightening and measuring staves of this type are not known.

For structural reasons, non-load-bearing interior walls may only be installed after the ceiling is completed. To avoid the first stones every layer of wall on corners and pillars, for example on doors, lowered again and again in practice, wooden posts are often used between the Floor and ceiling set up vertically and wedged. Then along the Post walled up vertically. Erecting the wooden posts requires two workers and can be very time consuming. Matching wooden posts, which also have to be straight, as well as wooden wedges must be looked for. Another complication arises with Walls of such walls by the fact that the last layer, even with standardized room heights Often it no longer fits under the ceiling, because even experienced bricklayers have the right one Not being able to maintain the joint thickness emotionally.

Setting up suitable stones for the final layer is very time-consuming and can usually only be avoided by ongoing controls.

The invention is based on the object, the wooden posts by a To replace device, which can be adapted to the height of the room and which of only one worker quickly set up between the floor and the ceiling and in the vertical can be brought. The device should remain sufficiently stable without fastening and should also display the standardized wall layer heights.

According to the invention the object is achieved in that the directional and Ruler made from a basic element, for example from a hollow profile, from an extendable one Head piece and, if required in individual cases, an extendable foot piece consists. One of the pieces usually the head piece, is elastic and consists of at least two parts, which by means of a spring element, for example are positively connected to one another by means of a spiral spring. The basic element has longitudinal movement slots at the head end and at the foot end. In Connect transversely protruding fasteners on the head piece and on the foot piece these can be released through the movement slots with the base element. Basic element and base have markings for the wall layer heights.

A construction example is shown in Figures 1 and 2 described below.

Figure 1 is a diagram of the invention, Figure 2 is a Longitudinal section. The base element 1 is a hollow profile and has movement slots at both ends 6 lengthways. At the top is the head piece 2 and at the bottom end is the foot piece 3 inserted into the base element 1 and with a threaded bolt protruding in the transverse direction 7 through the movement slot 6 by means of a wing nut with the base element 1 releasably connected. The head piece 2 consists of two parts, which by means of a spiral spring 4 are positively connected to each other. Basic element 1 and base 3 have Markings 5, from which the wall layer heights can be read.

In practical use, the device is opened by pulling out the foot piece and the head piece adapted to the height of the room. Then the head piece is reduced by a few inches moved out further. If the device is now compressed by compressing the spiral spring between If the floor and ceiling are set up, the spring action allows it to stand still be placed vertically and aligned by tapping.

The advantage of the invention lies in the saving of working time.

Claims (2)

Claims 1. Guide and yardstick, especially for bricklayers, characterized in that a base element (1), for example a hollow profile, can be extended is by a head piece (2) that can be moved in the longitudinal direction of the slat and, if it is required in individual cases by a slat that can be moved in the longitudinal direction of the slat Foot piece (3) such that the parts are nested and pushed into one another can be moored in any position, one of which, as a rule the head piece (2), is elastic and consists of at least two parts, which means a spring element (4), for example a spiral spring, non-positively with one another are connected and that the base element (1) and the foot piece (3), if it is in individual cases is required lengthwise at certain intervals markings (5), for example Notches, which are arranged like a yardstick for wall layer heights are and that the base element (1), if it is a hollow profile, at the upper end for the head piece (2) and optionally at the lower end for the foot piece (3) in the longitudinal direction running movement slots (6) and that the head piece (2) and the foot piece (3) connecting means (7) protruding in the transverse direction, e.g. threaded bolts, have, which are inserted through the movement slot (6), a detachable connection to the base element (1), for example by means of wing nuts. 2. straightening and measuring rod according to claim 1, characterized in that one of the pieces (2), (3) is resiliently connected to the base element (1), if none the part is elastic and resilient in itself.
