BG63700B1 - Guiding strip in the plastering of building surfaces - Google Patents

Abstract

The guiding strip is used in plastering of internal and external walls and in making floor cementing in civil engineering. It comprises a rectangular steel profile (1) with holes and supporting elements, fitted on the surface which is being plastered (3). The supporting elements are U-shaped plates (2) the horizontal walls of which are fitted to the surface (3), and on their vertical walls holes (6) are drilled at different heights for fitting and adjusting the profile (1). At both its ends it has holes (12) for fitting to plates (2) of a middle hole (15) and intermediate holes (17 and 18). Profile (1) is attached to the surface (3) which is being plastered by a bolt (13) screwed into a nut (14) across the middle hole (15), and the intermediate holes (17) nd 18) are for additional strengthening. If necessary, additional lifting steel plates with holes (9), mounted between the vertical walls of profile (1) and plates (2) are provided. 2 claims, 4 figures

Description

Field of the art

The leading strip is used for plastering of external and internal walls when laying flooring in construction.

State of the art

It is known to apply wall plasters and floor screeds using strips called "mothers" made from the material that will be used to make the screed. They are executed by hand, first applying and leveling the edges and middle of the strip. After waiting for a certain drying time, fill the entire strip with a solution. Again, it is almost completely dry, so that the "mother" can not be destroyed when laying the screed.

There is a leading metal strip for the application of wall screed, including a metal profile with slotted openings and supporting elements attached to the plastered surface. The metal profile is adjustable in height by a slider for fitting, bolts and an eccentric lock (1).

Technical nature

The problem to be solved by the invention is to create a leading strip which has a simple and easy to manufacture and assemble structure to save working time in building construction work.

The leading strip for plastering of construction surfaces includes a metal profile with holes and supporting elements attached to the plastered surface. The support elements are U-shaped strips whose horizontal walls are attached to the plastered surface, and their vertical walls are drilled in different heights for fixing and adjusting the metal profile. It is rectangular and has at its end openings for fixing to the U-shaped strips, a middle hole and intermediate holes. The metal rectangular profile is fastened to the plasticized surface against deformations along the vertical axis in its middle section by a bolt wound in a nut through the middle aperture, and the intermediate holes are for further strengthening.

There are also additional lifting metal plates with holes that are mounted between the vertical walls of the rectangular metal profile and the U-shaped strips when the height of the vertical walls of the U-shaped strips is not sufficient to fix the rectangular metal profile in the desired horizontal position.

The advantages of the invention are that, thanks to the simplified construction, the guide strip is easy to manufacture and install and can be used for both wall plaster and floor screed laying. The attachment to the plastered construction surface is more stable and has a greater possibility of adjusting the strip depending on the need. With the help of two guide strips, according to the invention, one field is formed and the plastering can be immediately applied. Once the work is done, the leading stripes are easily removed and used to form a new field.

Description of Annex Figures

The invention is illustrated with exemplary embodiments shown in the accompanying drawings, of which:

Figure 1 is a side view with partial sectional views of the leading strip when laying flooring;

Figure 2 - Strengthening the metal profile to the construction surface in its middle section in the realization of wall plasters;

FIG. 3 is a section A-A of FIG. 1; Figure 4 is a section B-B of Figure 1.

Examples of implementation

An exemplary embodiment for laying floor screed is shown in Figure 1. The rectangular metal profile 1 is supported by two U-shaped strips 2. They are fixed to the construction surface 3 by screws 4 through apertures 5. The rectangular metal profile 1 by using the openings 6 of the pillar strips 2 is adjusted horizontally and fixed by bolts 7 and nuts 8. In the case of insufficient height of the vertical walls of the U-bar, on one side between the U-shaped plate 2 and the vertex metal profile 1 at one end of the guide strip are mounted lifting metal strips 9 by bolts 10 and nuts 11 . hole 12 at both ends of the rectangular metal profile 1 are for further adjustment of its height. The reinforcement against deformation in the middle of the rectangular metal profile 1 is effected by a bolt 13 wound through a central bore 15 in a nut 14 welded to the underside of the rectangular metal profile 1 until it touches the construction surface 3. The mounting of the guide strip starts at the highest point in the room. With two such strips, a field is created that can be immediately smeared. Once the work on this field is done, the leading stripes are removed and a new field is formed.

In another exemplary embodiment, the guide strip is used for plastering the construction surfaces for exterior and interior wall plasters. Its two-end mounting is as described above. Figure 2 shows the reinforcement of the rectangular metal profile 1 against deformation in the middle of the vertical axis when the invention is used for exterior and interior wall plasters. For additional reinforcement, a screw 16 is screwed into a dowel at the construction surface 3 through intermediate holes 17 and 18. The choice of which pair of intermediate holes 17 and 18 is to be used depends on which holes are against a brick or against a joint between the bricks.
