Description

The invention relates to construction, more specifically, to tools for applying and leveling plaster mortar on window and door slopes.

Plaster slopes are the most common type of slope finish, suitable for use both inside and outside. The upper slopes within the same room should be on the same horizontal line. The upper slopes on the facades should be in one straight line, regardless of the number of windows and the length of the walls of the facade. Side slopes should be located vertically on one vertical line along the entire height of the building. Slopes are made with the angle of dawn, leaving the distance between the outer borders of the slopes wider than between the internal. Creating ideal planes and angles is the main task of the plasterer.

Plastering the slopes is carried out after carefully attaching the window and door frames, filling the space between the box (item 4 in figure 1) and the walls with insulation (item 5 in figure 1) and after the main walls are plastered and wiped. First, plaster the upper slope, hanging the rule (flat rail, lighthouse - item 1 in figure 1) at the measured angles of dawn. Rule 1 is fixed with nails, clamps, crutches or frosted with plaster dough. To level the solution to the level of the slope, a wooden tool called a malk is made (see pos. 2 in figure 1). This tool is the closest to the proposed solution. Malka 2 is recommended to be made from a pine or spruce bar. At one end, she has a calibration cutout 3. The length of the fry depends on the width of the slope, the thickness of the fry is 25-32 mm. At one end, the fry 2 make a cut 3 ½ of the thickness of the box 4, with which the fry 2 moves along the box 4. This subsequently ensures the normal opening of the window sashes. Malka 2 cutout 3 is installed on the box 4, and the other end to rule 1. After setting the solution, the edge of the slope and the walls are aligned.

After removing rule 1 from the horizontal slope and making corrections, they begin to plaster the side slopes. Thus, to finish the slopes on each window, you have to hang three rules and measure and check the angle of dawn many times.

The disadvantages of the known tool - small - are the need for its manufacture for each specific case, depending on the specific geometry around the window or door. The wooden fry has irregularities and eventually swells, warps and deforms from a wet solution, which leads to marriage. The use of metal-studded malks can lead to injuries to the hands.

The objective of the invention is to provide a more versatile tool for plastering the slopes of window and door openings, which could be used with any size of openings.

The problem is solved with the help of a plastering tool containing two jaws for clamping the slats, a bracket rigidly connected to the jaws and mounted on the edge of them, a movable rail mounted on the bracket in the groove, means for fixing the rail on the bracket, made in the form of thread-mounted bracket of screws and opposite supporting screws of support platforms.

A rail can be mounted on the rail, which stands for the contours of the rail.

At the end of the rail near the roller, there may be a protrusion extending beyond the diameter of the roller.

The invention allows for easy and high-quality selection of the required angle of slope dawn, increases the quality of decoration and labor productivity. For plastering all slopes, you can use the standard metal rule. The tool can be safely, reliably, repeatedly without running out of resources and time limits used in plastering.

The invention is illustrated by figures.

Figure 1 shows a known tool (malka) and its use. Figure 2 shows a General view of the proposed tool, Fig.3-5 - types of the proposed tool, explaining its design.

The tool contains two jaws: the upper 11 and the lower 12, designed to clamp the strap (rule) 21 (part of rule 21 is shown in dotted lines in FIG. 3). On the upper jaw 11 there are screws 13 for clamping the strap (rule) 21 to the lower jaw 12. The screws 13 are wing-shaped for ease of use.

The jaws 11 and 12 are connected by a wall 14 (rear — see FIG. 5), so that the jaw 11, the wall 14 and the jaw 12 form a U-shaped profile. Due to the presence of the wall 14, the jaws 11 and 12 do not diverge.

You can use shortened rule 21 to handle the slope.

The tool comprises a bracket 15 rigidly connected to the jaws 11 and 12, mounted to the edge of the jaws 11 and 12, and also a movable rail 16 mounted on the bracket 15 in the groove 17, and means for fixing the rail 16 on the bracket 15. This tool is made in the form screws 18 installed in the thread on the bracket 15, and support pads 19 located opposite the screws 18. Screws 18, the rail 16 can be clamped between the bracket 15 and the support pads 19. The screws 18 are also made wing-shaped.

On the rail 16 at its end, which is closer to the jaws 11 and 12, a roller 20 is mounted (articulated, rotatable), which protrudes beyond the contours of the rail 16 (see figure 5).

At the end of the rack 16 near the roller 20 there is a protrusion 23 that extends beyond the diameter of the roller 20.

The tool is used as follows.

After installing a window or door frame at the edges of the opening, rules are fixed as beacons, determining the angle of dawn. The proposed tool is installed on one side of the meter or shortened rule 21, which will align the plaster, clamping it between the jaws 11 and 12 and fixing the wing screws 13.

Then they select and use the adjusting screws 18 to fix the position of the rack 16 relative to the rule 21 inserted into the jaws 11 and 12 so that rule 21 could move with its free end according to the beacon rule fixed along the edge of the opening, and the roller 20 could roll along the window or door frame, which in this case also serves as a beacon.

It is possible in some situations that a protrusion 23, rather than a roller 20, moves along a window or door frame.

Then the plaster mass is applied to the slope and the plaster layer is leveled with a tuned tool, on the one hand, rule 21 next to the roller 20, pressing it to the box, on the other hand, to the hinged rule-beacon, and lead from the bottom up or along the horizontal slope, depending on the convenience.
