BRICKLAYING DEVICE

Abstract

This utility model relates to hand-held construction tools for bricklaying. The bricklaying device comprises an elongated body with a wave-shaped lower projection on the underside, and removable end strips mounted on the ends of the body. The lower projection is designed to rest against the face of the brickwork, setting the depth and forming the joint between the bricks, while the upper part of the body serves as a guide surface for uniformly drawing and leveling the mortar. The removable end strips are designed to limit the spread of mortar in the transverse direction and contain it within the work area, including at building corners, in window, door, and other openings. The technical result consists of ensuring uniform leveling of the mortar and simultaneously forming the joint between the bricks during bricklaying, as well as preventing mortar from dripping onto the facing surface of the masonry.2 pages.

Description

[0001] The utility model relates to hand-held construction tools for bricklaying and is designed for applying and leveling masonry mortar on the surface of the masonry while simultaneously forming an inter-brick seam.

[0002] A bricklaying device, patented under US20140345231A1, comprises a leveling lever and a gripping area for securing an auxiliary post, ensuring vertical and horizontal alignment of bricks. The device requires an additional support and is not intended for applying and leveling mortar directly onto the masonry surface.

[0003] Also known is a manual bricklaying device (patent RU222924U1), which contains parallel guides and crossbars with adjustable spacing between the guides. This device ensures the positioning of bricks, but is not intended for simultaneously leveling mortar and forming joints between bricks.

[0004] Known solutions do not provide for the simultaneous leveling of masonry mortar, the formation of inter-brick joints and the limitation of mortar spreading within the working area using a single device.

[0005] The technical result consists in ensuring uniform leveling of the masonry mortar and simultaneously forming an inter-brick joint when performing brickwork, as well as preventing the masonry mortar from flowing onto the facing part of the masonry.

[0006] The specified technical result is achieved in that the bricklaying device contains an elongated body, on the lower side of which a lower projection of a wave-shaped form is made, and removable end strips are installed along the ends of the body.

[0007] The lower wave-shaped projection is designed to rest against the front part of the brickwork, set the depth of the inter-brick joint and level the already formed inter-brick joint when moving the device along the surface of the masonry.

[0008] The technical solution is explained by drawings:

[0009] Fig. 1 - device, bottom view.

[0010] Fig. 2 - device, top view.

[0011] The drawings indicate:

[0012] 1 - oblong body;

[0013] 2 - lower projection of wave shape;

[0014] 3 - removable end strips.

[0015] The elongated body is designed to rest on one edge of the brickwork, while the upper part of the body forms a guide surface along which the masonry mixture is evenly pulled and smoothed with a trowel.

[0016] Removable end strips are designed to limit the spread of masonry mortar in the transverse direction and keep it within the working area, including at the corners of buildings, in window, door and other openings.

[0017] In a particular version, the removable end strips are designed with the possibility of being attached to and detached from the body.

[0018] In one embodiment, the distance between the edge of body 1 and the edge of lower projection 2 is slightly greater than the width of a brick. In one embodiment, the distance between the edge of body 1 and the edge of lower projection 2 is slightly greater than the width of a brick. This arrangement is necessary to allow for the bonding of brick walls where one wall meets another. When bonding, part of the brick in one row should extend into the adjoining wall, so the device must be able to apply and level the mortar, extending into the adjoining area. Because this distance is slightly greater than the width of a brick, the device can be moved to the adjoining wall and form a layer of mortar in the bonding area without interference from the body.

[0019] The bricklaying device is designed as an elongated body 1, preferably made of metal, ensuring sufficient structural rigidity when working with mortar. Body 1 forms the main load-bearing part of the device and serves as a base for the lower projection 2 and removable end strips 3.

[0020] On the underside of the housing 1, a wave-shaped lower projection 2 extends along the working portion of the device. Lower projection 2 is designed to contact the face of the brickwork and the joint between bricks as the device moves along the surface. The wave-shaped shape of the lower projection 2 ensures contact with the face of the brickwork, sets the joint depth, reduces localized mortar accumulation, and promotes the formation of an even joint between bricks along the entire length of the device's travel. Due to this, lower projection 2 simultaneously serves to form the joint and smooth out the existing joint between bricks.

[0021] Removable end strips 3 are installed along the ends of body 1. End strips 3 limit the transverse spread of mortar, keep the mortar within the work area, and ensure more even spreading of the mortar along the masonry surface. End strips 3 are particularly effective when working at building corners, in window, door, and other openings where it is necessary to prevent mortar from flowing onto the facing surface of the masonry. End strips 3 are designed to be attached to and detached from body 1. In one embodiment, end strips 3 are rigidly fastened, for example, using protrusions and a clamping connection, which prevents the strips from shifting or becoming detached during work.

[0022] Before laying, place the device on the wall surface or on an existing row of bricks so that the lower projection 2 faces the face of the masonry and the joint between the bricks, and the edge of the upper part of the body 1 rests on the brickwork. After installing the device, apply mortar to the work surface within the area bounded by the body 1 and the end strips 3.

[0023] Next, using the trowel, using the top of the body 1 as a guide, evenly pull and smooth the mortar along the edge of the body. The end strips 3 hold the mortar within the working area and prevent it from spreading beyond the leveling area, while the lower projection 2, moving along the joint between bricks, sets the joint depth and simultaneously levels it. As a result, a leveled mortar layer and a formed joint between bricks are formed on the masonry surface.

[0024] After the mortar has been leveled, the device is removed from the masonry, and bricks are laid on the prepared layer. Thus, the device is used not as a permanent element in the masonry, but as a temporary device for preparing the mortar layer and forming the joint before laying the bricks.

[0025] In one embodiment, the distance between the edge of the body 1 and the edge of the lower projection 2 is slightly greater than the width of a brick. This design allows the device to be used for bonding brickwork at wall abutments and when entering a mating section of masonry.

[0026] The use of the device allows you to level the masonry mortar and form the inter-brick joint with one device without using a separate tool for joint expansion.
