[0001] The subject of the utility model is a new and original frame for proportioning and
application of mortar, intended for use in building industry.
[0002] There are known different devices for proportioning of mortar and facilitating its
application.
[0003] From the description of the utility model no.
Ru 58515 there is known "An element for the application of an adhesive and for the sealing
of joints", which has a form of a cuboid, on one wall of which there is a narrowing
tunnel with an arched vault. The base of the narrowing tunnel has the shape of isosceles
trapezium.
[0004] From the description of the invention no.
185741 there is known "A device for continuous and even pouring of abrasive grains, especially
onto a moving paper ribbon or linen base in a continuous process of the manufacture
of poured abrasive products", which has a vibrating pouring plate slightly turned
down from the plane forcing vibrations; and the pouring plate is fixed to a rigid
structural beam. The beam is fixed permanently to flexible elements. The pouring plate
is in a slight, vertical distance from the pouring throat of the open container, and
the central part of the rear wall of the structural beam is connected to a vibrator.
Under the outlet opening there is fixed at least one, replaceable, not too wide, flat
sieve with the mesh size depending on the granulation of poured abrasive grains.
[0005] The essence of the solution consists in the fact that in the central part of the
quadrangular through construction there is placed a strip, and on one side of the
quadrangular construction there are placed fastenings; and the fastenings are placed
at the ends of the construction in such a way that they form a right angle with the
construction, and fastenings are placed over the construction, on its both shorter
sides.
[0006] The frame for proportioning and application of mortar according to the model facilitates
even application and proportioning of ready mortar. As a result of the application
of the frame according to the model, the wall is built evenly (always the same thickness
of joint). Therefore, the economic use of mortar is guaranteed, which automatically
translates into financial savings. Due to the construction of the frame (the internal
dimensions of the frame (1) are smaller than its external dimensions), in the process
of bricklaying (adjusting and pressing of, e.g., bricks) the joint always remains
on the brick surface and does not go beyond the dimensions of the bricks/ the constructed
wall. Therefore, the use of the frame according to the model and the even application
of the mortar makes the constructed wall aesthetic due to the optical appearance of
joints.
[0007] Additionally, the use of the frame eliminates thermal bridges, guaranteeing the isolation
between the cold and warm spheres of the constructed wall, which gives additional
savings during heating and exploitation of the building.
[0008] The width of the frame for proportioning and application of mortar according to the
model corresponds to the width of the brick, hollow brick, or other material, from
which the wall is constructed. The length of the frame is not determined, and utility
and functional aspects are decisive: it should be comfortable to hold and move by
one person. The application of the mortar is made in the following way: on the constructed
fragment of the wall the frame according to the model is placed, then the mortar is
applied in such a way that it fulfills the whole depth of the frame. All that goes
beyond the frame is removed and that is why the joints in the wall are always the
same. In the centre of the frame there is a strip causing the appearance of air spaces
in the mortar during the construction. Due to the air spaces the so-called thermal
bridge is eliminated and cold and warm spheres in the constructed wall become isolated.
After the mortar is put on the place limited by the frame and its excess is removed,
the frame is taken away and a subsequent layer of bricks is laid on the mortar formed
in that way.
[0009] The subject of the utility model is presented on enclosed illustrations, fig. 1 -
4, where the frame has been shown according to the model:
Fig. 1 - the frame in the perspective projection
Fig. 2 - the frame seen from above
Fig. 3 - the frame seen from the longer side
Fig. 4 - the frame seen from the shorter side,
[0010] The frame for proportioning and application of mortar according to the model consists
of a quadrangular, rigid and through construction (1), which has the same depth on
its whole area. The frame is placed on the constructed wall and the whole depth of
the frame is filled with mortar. On one side of the quadrangular construction (1)
there are placed fastenings (3), which guarantee a stable and adjustable positioning
of the frame, and consequently, of mortar on the constructed wall. The fastenings
form a right angle with the construction (1). It prevents the frame from being unsteady,
as well as its movements during the application of the mortar and the removal of its
excess. Along the whole central part of the quadrangular construction (1) there is
placed a strip (2). During the bricklaying the strip causes the appearance of air
spaces in the mortar, thus eliminating thermal bridges. The use of the strip (2) contributes
to better isolation between the cold and warm spheres of the constructed wall. Over
the construction (1), on its both shorter sides there are placed handles (4) for carrying
of the whole frame.
An embodiment:
[0011] The frame for proportioning and application of mortar according to the model consists
of a rectangular, metal construction (1), which has the same depth on its whole area.
Due to the construction of the frame (internal dimensions are smaller from external
ones by 1 cm), during the bricklaying process (adjusting and pressing of bricks or
other material, from which the wall is constructed) the joint always remains on the
brick surface and does not go beyond the dimensions of the brick/ building material.
After the frame is placed on the constructed wall, the whole depth of the frame is
filled with mortar. Therefore the wall is even (the thickness of the joint is fixed
at 1cm). The process guarantees an economic use of mortar, which automatically brings
about financial savings. On one side of a quadrangular construction (1) there are
placed fastenings which allow to fix the frame on the wall in a stable way. Along
the whole central part of the quadrangular construction (1) there is placed a strip
(2) of the uniform width. During the bricklaying the strip causes the appearance of
air spaces in the mortar. Over the construction (1), at its both shorter sides, there
are placed rounded handles (4) for carrying of the frame.
[0012] The embodiment does not limit the model.
1. The frame for proportioning and application of mortar with a quadrangular rigid construction,
handles and fastenings, characterised by the fact that in the central part of a quadrangular through construction (1) there
is placed a strip (2), and on one side of the quadrangular construction (1) there
are fastenings, and the fastenings are placed at the ends of the construction (1)
in such a way that they form a straight angle with the construction (1), and over
the construction (1), at its both shorter sides, there are placed handles (4).
