CH680677A5 - Mortar applicator for wall construction - comprising container open at top and bottom, equipped with handles and skids to deposit even layer of mortar on top of wall and fill vertical gaps between blocks - Google Patents

Abstract

The mortar applicator, especially for use when building a wall of blocks or bricks, consists of a container (1-4) which is open at the top and bottom, and has sides with lower edges (7) overlapping the faces of the wall. The open bottom of the container has a central projection (15) and two side skids which travel along the edges of the wall, while the upper front and rear faces (3,4) of the container have handles (12,13) by which the container is moved along the top of the wall. During operation the container is filled with mortar (6) and then moved along the wall so that the mortar fills any vertical gaps (11) between blocks or bricks and is deposited in a layer (6) along the top of the wall, ready to receive the next course of blocks or bricks. USE/ADVANTAGE - Reduced time taken to apply cement mortar to blocks or bricks.

Description

The invention relates to an apparatus for applying mortar during the construction of a studded or brick wall.

When building a studded or brick wall, apply the mortar manually using a trowel. Executed by a person skilled in the art, this process gives satisfactory results but it has the disadvantage of being costly in working hours.

The object of the present invention is to provide a person skilled in the art with an apparatus for applying mortar during the construction of a studded wall, which makes it possible to obtain the same result as that obtained by the technique. traditional, but in a significantly shorter time. This object is achieved by the apparatus which is the subject of the invention and which is in accordance with claim 1.

The accompanying drawings show, by way of example, an embodiment of the apparatus according to the invention.

Fig. 1 is a perspective view of this embodiment, the device being shown in operation on a stud wall under construction.

Fig. 2 is a side view of this embodiment.

Fig. 3 is a view from the rear of this embodiment. The device being shown placed on a wall of studs.

The device consists of a container formed by four walls. The two side walls 1, 2 (the cheeks) are trapezoidal in shape and are arranged vertically and parallel to a certain distance from each other. The front 3 and rear 4 walls are generally rectangular in shape, oblique and fixed to the cheeks by a quick fixing device of known type. These four walls together form an open container at the top and bottom. When the device is placed flat on the top of an alignment of studs as shown in fig. 1 and 3, the upper face of the pads 5 fulfills the bottom function for the container, which can then be filled with mortar 6 from the top, which remains open. According to this embodiment, the width of a device is determined during its assembly as a function of the thickness of the wall to be constructed by means of studs, so that the distance between the two cheeks 1, 2 of l the device is very slightly greater than the width of the studs. The width of the device is determined by choosing the walls 3 and 4 from a set of walls of different widths.

The two plates constituting the cheeks 1,2 extend downward for a certain distance below the level of the lower edges of the two walls 3, 4 so that when the apparatus is placed on an alignment of studs, these two parts 7, 8 are on either side of the studs parallel to their lateral faces, thus constituting two guides which hold the device in the axis of the studs (fig. 1 and 3).

Two pads 9,10 are each fixed against the inner face of one of the cheeks 1, 2, slightly below the lower edges of the two plates 3, 4, so that when the pads are placed on the surface of the studs there remains a space between the lower edges of the plates 3, 4 and the surface of the studs. Arranged in this way, the pads allow the device to slide on the alignment of the studs without requiring excessive efforts.

When the device is placed on a wall under construction and it is filled with mortar, the latter will fill the joints 11 between the studs and adhere to the upper surface thereof. When the apparatus is moved by hand, by means of the handles 12, 13 along the axis of the alignment of the studs, and in the direction of the arrow 14, only a thickness of mortar corresponding to the height of the free space between the top of the studs and the lower edge of the rear knife can adhere to the studs. The rest of the mortar will be retained in the device by the action of the back plate 4. As the device advances, the mortar will be applied to new portions of the alignment of studs (fig . 1), the opening at the top of the container making it possible to top up with mortar at any time. As soon as the device has passed over a portion of the wall, it will be ready to receive the next row of studs.

The lower edge of the rear wall 4 is cut as seen at 15 in FIGS. 1 and 3, to form in the layer of mortar thus deposited on the pads a median depression 16 in which part of the mortar can be driven back when a new row of studs is placed on this mortar. In the case of a thin wall, the device may not have such a part 15, the lower edge of the rear plate 4 comprising only the two lateral projections intended to limit the quantity of mortar in the vicinity of the edges of the Wall. The apparatus described makes it possible to very significantly reduce the mason's working time, compared to the traditional method.

Claims (3)

Claims 1. Apparatus for applying the mortar during the construction of a studded or brick wall, characterized in that it comprises a container (1, 2, 3, 4) for containing the mortar (6), open to its upper part for introducing the mortar and at its lower part which is of width substantially equal to the thickness of the wall to allow, when the apparatus is placed on the upper part of a wall under construction, the flow of the mortar ( 6) through the lower opening to fill the joints (11) between the studs and cover the upper face thereof, this lower opening being arranged so that when the appliance is in the working position on a wall in construction, there remains a free space of determined size between the top of the pads and the lower edge of a rear portion (4) of the container, so that when the device is moved on the pads, a limited thickness and substantially mortar constant be thimble laid, the side parts of the container having downward extensions (7, 8) intended to serve as guides during this movement, by applying to both sides of the wall. 5 10 15 20 25 30 35 40 45 50 55 60 65 2 3. Apparatus according to claim 1 or 2, characterized in that the container (1, 2, 3, 4) has a rear wall (4), whose lower edge has a profile intended to produce in the mortar layer (6 ) deposited on the upper surface of the wall under construction with strips of different thicknesses. 5 10 15 20 25 30 35 40 45 50 55 60 65 3 3 CH 680 677 A5 2. Apparatus according to claim 1, characterized in that it comprises two pads (9,10) provided to slide along the edges of the top of the wall under construction and to ensure the desired distance between the bottom of the container (1, 2, 3, 4) and this vertex.
