Description

[0001] MANUAL BRICKLAYING DEVICE

[0002] The utility model relates to the field of construction, namely to a universal device for laying and facing brick walls, and can be used for civil and industrial construction projects with any brick size and any length of brickwork rows.

[0003] One of the most complex construction processes is the production of brick or block masonry. The widely used bricklaying method consists of several stages:

[0004] 1) Laying the first row of bricks on the base (support platform or foundation).

[0005] A layer of mortar is applied to the base and manually leveled to the specified thickness. The first row of bricks is then laid on top of the mortar layer. To ensure the bricks are laid evenly, a string (rope) is stretched from one edge of the wall to the other, visually aligning the first row of bricks. To level the bricks, tap the trowel handle against the brick's surface until it reaches the level indicated by the string. Any excess mortar squeezed out from under the brickwork is collected with the trowel from both the outside and inside.

[0006] 2) Laying the second and subsequent rows of bricks on top of the first row of bricks.

[0007] A layer of mortar is applied to the first row of bricks and smoothed by hand to the specified thickness. The second (and subsequent) rows of bricks are then laid on top of this mortar layer. To ensure the bricks are laid evenly, a string (or rope) is stretched from one edge of the wall to the other, visually aligning the rows of bricks. To level the bricks, tap the surface of the brick with a trowel until it sinks to the level indicated by the string, forcing the flexible mortar underneath.

[0008] 3) Grouting the masonry joints.

[0009] 4) The complexity of the bricklaying process stems from the fact that each row of bricks is laid on top of the previous row using liquid mortar, creating a mortar joint that must meet specified joint height parameters. This joint height is determined by the architectural pattern of the brickwork or by the specified wall height parameters, taking into account the brick height and the joint height.

[0010] Laying bricks with wet mortar requires special skills to ensure that the force applied to the brick does not push the mortar out of the joint, thereby distorting the joint's dimensions. Maintaining a uniform joint height becomes more difficult as the brickwork increases with each new course, since not only is the mortar of the last course in a liquid state, but the preceding lower joints are also in a liquid state. As a result, the bricklayer cannot lay the brickwork high enough, because the mortar in the lower joints will succumb to the pressure and protrude, causing the joints of the lower courses to change in height. A further complication is that the joints of the lower courses will change in height unevenly, with a possible slope, which can lead to the entire masonry mass collapsing from the design plane, either outward or inward.

[0011] The information provided shows that bricklaying is a very labor-intensive process that requires special skills and training of specialists.

[0012] To simplify bricklaying work, various devices are currently used.

[0013] For example, a construction and installation profile for laying a wall from bricks or blocks with longitudinal grooves is known (RU Patent No. 73892, published on June 10, 2008), which is a built-in structure and contains two parallel guides connected to each other by transverse strips, while the guides have shelves made with the possibility of their placement in the longitudinal grooves of a brick or block.

[0014] After laying the first row of bricks or blocks, a construction profile is placed on them. The downward-facing shelves of the guides are inserted into the grooves of the bricks, ensuring their complete alignment. The space between the shelves is then filled from above with mortar, which penetrates the bricks. The next row of building or facing bricks or blocks is then laid, with the upward-facing shelves inserted into the grooves of these bricks. The laying cycle is then repeated in a similar manner until the wall is fully erected. A unique feature of this design is its use as a built-in element, which cannot be moved or removed from the wall structure. This ensures uniform gap heights between adjacent horizontal rows of bricks, achieving high repeatability and enhancing aesthetics.Each top layer of brick laid rests on the end of the guide profile below, without squeezing out the mortar underneath and without causing uncontrolled displacement of the lower laid rows of masonry, which significantly speeds up and simplifies the process of building a wall.

[0015] However, the embedded profile can only be used for one size of bricks and blocks with a certain specified width, which limits its functionality.

[0016] In addition, this design is intended for use only with the type of bricks or blocks that have longitudinal grooves for accommodating guide shelves, which increases the labor intensity of manufacturing this special type of bricks or blocks and complicates construction.

[0017] A device for manual bricklaying (RU Patent No. 222924, published November 18, 2023) is considered the closest analogue to the claimed solution. It consists of a built-in structure comprising two parallel guides and crossbars, the ends of which are connected to the guides. The guides are adjustable relative to each other to adjust the distance between the guides according to the brick dimensions. The crossbars can be flexible. These crossbars can also be made of metal wires, flexible plastic crossbars, etc.

[0018] The ability to move the guides relative to each other allows for adjustment of the distance between the device's guides, thereby changing the width of the device to match the width of the brick being used, allowing the device to be used for various brick and block sizes. In this case, when tapped, the brick settles downward until it rests against the ends of the device's guides. The crossbars maintain the device's structure in its original shape, preventing the guides from spreading beyond the brickwork. This not only ensures increased speed of wall installation but also ensures reliable operation without requiring highly qualified workers.

[0019] However, the technology for manufacturing such a device also has a complexity associated with the labor-intensive process of forming the joints of parallel guides and crossbars to ensure the mobility of the structure when its width changes.

[0020] The technical problem of this utility model is the creation of a device for manual brick laying, which allows for the creation of a universal embedded structure that accelerates the construction process and is used for the construction of a wall from bricks of any size and the formation of rows of brickwork of any length.

[0021] The technical result of the invention is a simplification of the manufacturing technology of a device for manual bricklaying due to the design features of the solution.

[0022] The technical result is achieved by using a device for manual bricklaying:

[0023] - representing a mortgage structure,

[0024] - containing oppositely located sections connected by transverse strips,

[0025] - in this case, the oppositely located sections of the device in their upper and lower zones are made with roundings.

[0026] In a particular case, the radii of rounding in the upper and lower zones of oppositely located sections of the device are made identical.

[0027] In this particular case, the rounding radii in the upper and lower zones of oppositely located sections of the device are different. In this particular case, the rounding of oppositely located sections of the device is achieved by bending the base of the device.

[0028] The base of the device is a metal wire, strip or tape made of composite materials, including epoxy resins reinforced with fiberglass.

[0029] In a particular case, the crossbars of the device are designed with the possibility of movement in the plane of their location.

[0030] The creation of rounded top and bottom sections of the device, located opposite each other, represents the simplest and fastest design option in terms of technological implementation. Such rounding can be achieved by forming bends in the device's base at the required distance, without the use of special molds. This simplifies the manufacturing process of the proposed device, allowing for the rapid production of multiple units and the commencement of construction.

[0031] The device features opposing sections and crossbars between them, which are movable in the plane of their placement. This accordion-type structure allows for flexible compression and expansion. In its compact configuration, the device takes up little space and is extremely convenient for storage or transportation. When extended, the device is ready for construction work.

[0032] The amount of movement of the crossbars determines the degree of expansion of the device and the distance between its opposite sections, allowing for adjustment of its length and width depending on the length of the brick row and the brick size. The more the crossbars are offset from their initial compressed position, the further the opposite sections of the device are separated from each other, the smaller the distance between the opposite sections, and the more elongated the device is, designed for longer brick rows and narrower brick widths. Accordingly, with a smaller offset of the crossbars, the device appears more compact and is suitable for shorter brick rows and wider brick widths.It is also possible that, with a maximum brick width corresponding to the length of the crossbars, several devices of the claimed design will be successively laid in one row of brickwork in order to “cover” the entire length of this row of brickwork.

[0033] At the same time, the device, which is a built-in structure, allows for reliable support for the row of bricks located above during its laying without the risk of the mortar being squeezed out and the masonry from a large number of rows collapsing outward or inward.

[0034] The claimed device is simple to manufacture and versatile in use, which speeds up and simplifies the overall construction process.

[0035] Fig. 1 shows a general view of the claimed device in a compressed position.

[0036] Fig. 2 shows a general view of the claimed device in an extended position.

[0037] Fig. 3 shows a section of the device with roundings in its upper and lower zones.

[0038] The universal device for manual brick laying contains oppositely located sections 1 and 2, connected by transverse strips 3 (Fig. 1, 2).

[0039] Oppositely located sections 1 and 2 of the device in their upper and lower zones are made with roundings 4 and 5, which represent the bending points of the wire, tape or similar base of the device (Fig. 3).

[0040] In this case, the radii of the specified roundings 4 and 5 can be made the same or different.

[0041] The device can be located in the initial compressed position (Fig. 1), and can also be stretched by moving the crossbars 3 in the plane of the location of these bars (Fig. 2).

[0042] The device can be made of metal, metal wire, or composite materials, including those based on fiberglass-reinforced epoxy resins. Example 1.

[0043] The device is a metal wire or a thin strip of composite materials.

[0044] In this case, it contains section 1 and section 2, located opposite each other. Г U (F и g 1).

[0045] Oppositely located sections 1 and 2 of the device in their upper and lower zones are made with roundings 4 and 5 (Fig. 3).

[0046] In this case, the rounding 4 in the upper zone of section 1 is connected to the first end of the crossbar 3, the second end of which is connected to the rounding 4 in the upper zone of section 2 of the device, which turns into the rounding 5 in the lower zone of section 2. Further, the rounding 5 of section 2 is connected to the first end of the crossbar 3, the second end of which is connected to the rounding 4 in the upper zone of the next section 1. Thus, the profile of the device is based on a triangle (Fig. 2).

[0047] In this case, fillet radii 4 and 5 are created with the same radius. If necessary, fillets 4 and 5 can be created with different radii.

[0048] To set the required length and width of the device, it is stretched to the sides, thereby moving the crossbars 3 and changing the distance between sections 1 and 2.

[0049] Next, the prepared and stretched device is placed on the row of bricks below, forming a seam of the required height between adjacent rows of bricks.

[0050] The method of laying bricks using the claimed design consists of the following stages:

[0051] 1) Laying the first row of bricks on the base (support platform, or foundation).

[0052] The device is placed lengthwise on the foundation, first stretched to set the desired length and width according to the parameters of the brick row and the brick size. Mortar is applied between the crossbars 3, which serve as support for the bricks laid on top. Then, using a trowel (spatula), the mortar is leveled by running the edge of the trowel along the ends of the crossbars 3 of the device, removing excess mortar. A brick is laid on top of the device filled with mortar. To ensure the uniformity of the masonry, a string (rope) is stretched from one edge of the wall to the other, along which the first row of bricks is visually aligned. To level the brick, the mason taps the trowel handle on the surface of the brick, lowering it until it touches the crossbars 3 of the device.

[0053] 2) Laying the second and subsequent rows of bricks on top of the first row of bricks.

[0054] The required units are laid out on the first row of bricks, spaced at the required distance. Mortar is applied between the 3 crossbars. The mortar is then leveled using a trowel (spatula), and excess mortar is removed. Bricks are laid on top of the laid units, filled with mortar. To ensure uniformity, a string (rope) is stretched from one edge of the wall to the other, visually aligning the rows of bricks. To level the bricks, tap the trowel handle on the surface of the brick, lowering the trowel until it touches the 3 crossbars.

[0055] The installed devices are not removed from the masonry.

[0056] Next, continue laying the required number of rows of bricks, without fear of the plasticity of the mortar, since the weight of the brick is transferred from row to row right down to the foundation not only through the plastic mortar, but through the transverse planks 3 of the device, which serve as supports for the brick.

[0057] In this case, the moisture absorption of the brick and the setting time of the mortar are less important than in conventional masonry methods. Also, the plasticity of the mortar is not one of the reasons for using hardening accelerators (catalysts).

[0058] 3) Grouting the masonry joints. Grouting can be done simultaneously with laying bricks from row to row, as there is no settling of the brick rows and the mortar does not bleed out under the pressure of the upper rows of masonry.

[0059] Thus, the proposed solution simplifies and increases the speed of building wall installation using any brick size, any length of brick row, and under any weather and climate conditions.
