Description

DEVICE FOR PLASTERING WINDOW AND DOOR ESCONSONS

Field of Invention

This invention relates to devices used in the finishing construction works, in particular, to devices for plastering the window and door plane esconsons.

Background art

Plaster esconsons are the most common type of finishing, which is performed both inside and outside the buildings. Esconsons are made at a slope or at the esconson angle that is formed due to the fact that the distance between the exterior boundaries of esconsons is greater than the distance between the inner boundaries of esconsons (inside the door or window opening). Esconsons on the facades of the buildings and inside a room should be alike, symmetrical, parallel and homogeneous and the exterior boundaries of esconsons should lie correspondingly on the same lines.

The need for new plastering tools arose through observation of the construction workers and plasterers and through quality analysis of work they perform when plastering door and window esconsons, as well as through estimate of time spent to perform this work.

Today, the process of plastering window and door esconsons is time- consuming, unsafe and low efficiency, and the tools used in this process are not as safe, easy-to-use, easy-to-adjust, reliable, accurate and efficient as it is normally required.

One of the tools used to level off the plaster applied on the building walls is a plastering rule. Normally, such plastering rule is made of a rigid material, aluminum, in the form of extruded shape protected against corrosion.

However, when plastering the window and door plane esconsons the plastering rule and wooden slats are most frequently used as a screed strip at the exterior boundary of the esconson and its outer corner. In practice it is very difficult and time-consuming to use these tools for leveling plaster applied to form the esconson and to reach the high quality of the work performed. Inconvenience and inexpediency of using plastering rules for leveling plaster on esconsons can be explained by several reasons, such as:

for using the plastering rule, the screed strip of the esconson outer boundary and the screed strip of the esconson inner boundary should be installed, which is a difficult and time-consuming operation if the worker does not have an appropriate professional qualification. The process itself takes a long time because of the need to precisely calculate and accurately perform the esconson angle and to uniformly insert the door frames or window casings into the esconson body; - glue mixture, on which screed strips (reference metal strips) are installed, takes additional time to dry up;

at the outer boundary of the esconson it is very difficult to maintain the right edge and a clear-cut outer esconson angle, in particular, it is difficult to fix the guide rails and screed strips.

In addition, the plastering rule cannot be used in the area next to the door or window casing because it has no sliding cut and sliding a rule on metal/plastic casings or frames damages and/or scratches them. Using a sliding cut is not advisable because the plastering rule is not a throwaway tool, on the one hand, and, the cut height parameters are individual and depend on the angle of esconson and the extent to which door frames or window casings are inserted into the esconson plaster, on the other hand.

The most relevant to the claimed device is a device for plastering the window and door plane esconsons comprising an element for leveling off the plaster applied to esconson and the pilot guides a wooden lath with a cut being used as an element for flattening out the applied plaster. Such wooden lath with a cut is connected to the handle. This device known as a floating rule is manufactured for fitting specific conditions and parameters of the window and door plane esconson plastering. Such device is related to a throw-away tool which should be discarded after plastering of window or door plane esconsons or even in the process of it due to deformation of floating rule under effect of moisture. During plastering of window and door plane esconsons the pilot guides are first installed and fixed on the outer edge of esconson. The plastering rule or lath is used as pilot guides. To level off the plaster applied on esconson, the window and door plane esconson plastering device is installed on the screed strips: door frames or window casings, and on the guiding rail mounted on the outer edge of esconson, and move it along these pilot guides. This device for plastering door frames or window casings known as a floating rule is installed by holding the cut in the wooden slat directed toward the door frame or window casing, and the other end toward the guide rail (screed strip) fixed to the outer edge of esconson.

The drawback of this device is lack of ability to adjust and change parameters for the element to level off the applied plaster and the need to manufacture a new device for each concrete window and door esconsons plastering process. This device can hardly be used to achieve the desired esconson angle and the extent of a door frame or window casing penetration into the esconson plaster. In addition, using this device is associated with low productivity and poor quality of plastering door and window plane esconsons.

Summary of invention

The main object of the this invention is to improve the device for plastering the window and door plane esconsons wherein - by virtue of the proposed elements and connections between them - the precise resulting esconson angle and the extent of the door frame or window casing penetration into the esconson plaster are achieved, thus ensuring high quality of door and window esconson plastering. In addition, the proposed device - along with high quality of this work - significantly reduces total time associated with its performance, saves on the materials and can be handled by construction workers with lesser professional skills.

The object is achieved by the device for plastering the window and door esconsons comprising an element to level off plaster applied on the esconson and pilot guides contacting with during plastering, wherein the element for leveling off the plaster applied on the esconson includes at least one end unit located at one of its ends containing an end cap with a longitudinal aperture in its work surface, an adjusting screw mounted in a frame of the end cap parallel to the longitudinal aperture. In addition, this element includes a round element fixed in the selected operating position in the frame of the end cap projected beyond the limits of its working surface and adapted to roll or slide on the surface of one of the pilot guides under contact during plastering and a locking element connected to the adjusting screw and the round element and adapted to control the movement of the round element in the longitudinal aperture of the frame of the end cap so as to fix the round element in the selected operating position.

In the preferred embodiments, it is advisable to provide a round element as a wheel that can rotate around its axis and is arranged essentially perpendicular to the working surface of the end cap, or a round element may be made as a closed sliding contact, each of them with a flange.

It is clear also that the external working surface of a rotating wheel may be made of rubberized material with a tread to ensure a more secure grip with a section of the window casing or door frame when moving the device and the flange surface or work surface of a closed sliding element adjacent to the wheel are recommended to polish. In this case, if a closed sliding element is ellipse-shaped the point where this element is mounted to the end cap's frame can be shifted relative to its center.

In the another the preferred embodiment of the present invention a plastering rule, a lath or a perforated metal strip can be selected as an element for leveling of plaster applied to esconson.

It is advisable also to use an appropriate portion of a window casing or door frame as one of the pilot guides for the element for levelling off plaster applied to esconson that comes in contact with the fixed round element.

When plastering window and door esconsons the claimed device allows to easily choose the desired esconson angle and the extent to which the door frame or window casing penetrates into the plaster body, that is, to form the geometry of esconson by copying the outer corner of the door or window frame perimeter at the side of esconson and transforming reference parameters into the given esconson plane. The end cap acts as a universal component in esconson plastering process, which makes it possible to use traditional plastering rules, laths or perforated metal strips as an element for levelling off the plaster applied on the esconson, and - due to the round element - combine this element with pilot guides in the form of a window casing or door frame. This device has significantly improved efficiency and quality of plastering the door and window esconsons, as well as the increased productivity of the door and window esconsons' plastering process and the reduced requirements for the professional qualification and skills of plasterers; the above advantages make it possible to greatly expand the number and enhance efficiency of workers capable of performing this work with high quality.

The principle of the device according to the invention is that the round element moves (rolls or slides) on a linear corner plane of the window casing or door frame at the side of the plastered esconson, thus copying parameters of the window casing or door frame outer corner at the side of the plastered esconson and transforming them in the specified parameters of esconson plane and angle. This process raises the quality of leveling off the plastered esconson planes and enhances precision of internal and external esconson angles while providing the same extent of the window casing or door frame penetration into the esconson body at all sides. Window casings and door frames are installed by using a plumb line (plumb level) and when applying the proposed device are used as one of pilot guides. A plastering rule installed at the outer angle of the esconson and the wall and fixed on the adjacent wall plane can be used as the second pilot guide for the element to level off plaster applied on the esconson.

A device for plastering window and door esconsons includes element 1 for leveling off plaster applied to esconson which in the prefferred embodiments is carried out as a plastering rule with a rectangular (simple) or trapezoidal shape, or a simple lath or perforated metal strip. At the opposite ends of element 1 for leveling off the plaster there is an end aperture 2 (Fig. 3). In the preferred embodiments, as shown in Fig. 1 -9, the proposed device can have an element 1 for leveling plaster applied on esconson with an end unit at each of its ends containing a round element 3, a locking element 4, a adjusting screw 5 and an end cap 6. According to another embodiment of the invention, element for leveling plaster applied on the esconson may have only one of such end unit (Fig. 10 - 1 1 ). According to the invention, each end cap 6 is carried out as a body with a working surface 7 that is set in the middle of element 1 for leveling off plaster applied on the esconson at the side of one of the opposite end apertures 2 so that the working surface 7 of the end cap 6 forms a butt end of the corresponding end of element 1 for leveling off plaster applied on esconson.

In all above embodiments, the round element 3 can be equipped with a flange 8, and the adjusting screw 5 can be locked in the end cap 6 with the pin 9 and can rotate. In the middle of the end cap 6 the locking element 4 is installed; it is connected with the adjusting screw 5 and the round element 3 by a screw 10. Each of the round elements 3 is mounted on the working surface 7 of respective end cap 6 outside the corresponding end cap of the element for leveling the applied plaster and can be adjusted and/or fixed in its position in the longitudinal aperture on the working surface 7 (aperture parallel to adjusting screw 5) by an appropriate adjustment screw 5, element 4 and screw 10.

Each round element 3 can roll if it is carried out as a wheel (Fig. 1 -4, 7 and 8), or slide if it is carried out as a closed sliding contact in a form, for example, a smooth oval or ellipse wheel (Fig. 5, 6 and 9).

In all above embodiments, the outer working surface of wheel 3 may be made of rubberized material with a micro-tread to ensure a more secure grip with a section of the window casing or door frame when moving the device and the flange surface adjacent to the wheel is recommended to polish.

It is clear that the external working surface of the round element 3 in the form of the closed sliding contact, for example, ellipse-shaped form is also advisable to make polished. In addition, the point where this element is mounted to the end cap's frame can be shifted from the center to expand the functionality of this device. Each end cap 6 is tightly seated and locked in the appropriate aperture 2 of element 1 .

In embodiments where a plastering rule is used as the element 1 , such element can have a rectangular (simple) or trapezoidal shape. Also, a lath or a perforated metal strip can serve as the element 1 . In particular, in one of the opposite ends of the element 1 for leveling plaster applied on esconson, the end node is installed whereas the other end may be made whole, as shown in Fig. 10, 1 1 .

Fig. 12 shows an example of a proposed device where the following references are the claimed used: a device 1 1 for plastering window and door esconsons, door frame 12, screed guide 13, plastered surface 14, wall 15, fixator 16 for construction and finishing works and plastered esconson 17.

Such device according to the claim can be used to plaster door frame esconsons in the following manner.

Before plastering the esconsons all adjacent walls (Fig. 12) should be plastered and scoured. The prescribed esconson angle is measured by a bevel square. Based on the angle, on the wall 15 according to plumb line (plumb level) the outer boundary of the esconson is referenced by installing and fixing the screed guide 13. The role of the second reference is played by the door frame 12 that is installed in accordance with the standards and leveled off. The excess amount of plaster is applied on the surface of end wall 14, which is to be plastered as an esconson. Using two reference points: the door frame 12 and the screed guide 13 fixed at the outer edge of esconson with fixator 16 for construction and finishing works, the device 1 1 for plastering window and door esconsons is installed so that a round element 3 located at one of the ends of the element 1 for leveling the applied plaster is placed on the reference point, the role of which is played by the door frame 12. By moving the element 4 and round element 3 in the frame of the end cap 6 relative to its working surface 7 by means of the adjusting screw 5 the desired depth of the door frame 12 is selected. The worker, who plasters the esconson, should apply an excess amount of plaster on the surface 14 and then with both hands install the device 1 1 for plastering window and door esconsons so that the round element 3 is located at the outer edge of the door frame 12 perimeter at the side of the plastered esconson and the portion of element 1 to leveling the applied plaster rests on the screed guide 13. Next, the device 1 1 is moved in conformity with two references: the door frame 12 and the screed guide 3. The round element 3 rolls if it is carried out as a wheel or slides if it is carried out as a smooth oval wheel along the door frame 12 so that parameters of the outer corner of the frame 12 at the side of the plastered esconson are copied and then transformed into specified parameters of esconson plane and angle for the esconson that is plastered. Simultaneously, the excess of plaster is flattened thus forming a plastered esconson 17 with high precision of symmetry and uniformity between internal and external esconson angles and planes. After that, the finished esconson 17 surface is scoured and the screed guide 13 mounted on the outer boundary of the esconson is removed.

The device for plastering door and window esconsons shown in Fig. 10, 1 1 is used in similar manner; in this case, it has one end cap 6 containing the locking element connected with the round element 3 and the adjusting screw 5. Such cap 6 is tightly set at one end of the plastering rule, preferably of a rectangular shape. It is clear that the device for plastering the window and door esconsons where the element 1 for leveling plaster applied to esconson has two end units with two round elements 3 is more versatile. Such element with two end sections is most frequently carried out in the form of trapezoidal plastering rule.

The proposed device for plastering the window and door esconsons provides nearly perfect esconsons within a short period time at minimal cost and with reduced requirements for professional qualification of the plasterer. The device is carried out so that it can be universally and continuously adjust any selected inside angle and assign the desired extent of window casing or door frame penetration into the esconson body.

Therefore, the above claimed device for plastering window and door esconsons:

increases efficiency and operational performance of plastering door and window esconsons;

improves the quality of plastered door and window esconsons;

improves the safety of works associated with plastering of door and window esconsons;

increases the accuracy of desired esconson angle and the extent of door frame or window casing penetration into the plastered body of the esconson;

reduces qualification requirements for workers plastering esconsons while increasing the number of workers who are able to quickly and efficiently perform this type of work.
