RU41038U1 - UNLOCKED MORTGAGE BLOCK - Google Patents

Abstract

The utility model relates to building materials and can be used for the construction of low-rise buildings for industrial and agricultural purposes. The block is made of a mixture of sand and cement in the ratio of ingredients 3: 1 in the generally accepted way and is a rectangular parallelepiped with protrusions - 3 and depressions - 5 on opposite spoon sides. The protrusions - 3 on the one and hollows - 5 on the other hand have the shape of truncated cones and are evenly located in a vertical plane in the middle of the block. The diameter of the larger base of the depression is equal to half the thickness of the block, and its depth is equal to a quarter of the thickness of the block. The protrusions - 3 and the depressions - 5 are located strictly opposite to each other, but the dimensions of the protrusions - 3 are smaller than the dimensions of the depressions - 5 by 3-7 mm so that when laying (mounting) the walls, the blocks are laid one on top of the other with self-fixing in the design position and without clearance between the lower bed plane - 6 upper blocks and the upper bed plane - 2 lower blocks.

Description

The utility model relates to building materials and can be used for the construction of low-rise buildings for industrial and agricultural purposes.

A wall block is known that contains a recess on the upper bed, repeating the shape of the block in plan and bounded by walls around the perimeter of the block, and on the lower bed there is a protrusion in the form of a truncated pyramid with a groove in the middle, recesses along the end faces and vertical voids between the bed surfaces. In this case, the protrusion in the lower bed is made in height less than the recess in the upper bed by the thickness of the mortar seam [1].

A disadvantage of the known design is the need for masonry walls for mortar.

The applicant knows a wall including building blocks stacked in rows with vertical through holes located symmetrically relative to the median vertical plane, connected by liners installed in the holes half protruding from the block plane. The liners are made separately and are two truncated cones connected by bases [2].

The specified design [2] is the closest analogue - the prototype of the proposed utility model, as the closest to it in the aggregate of essential features.

The disadvantages of the known design, according to the applicant, are:

- the need for the manufacture of components - inserts - and, as a result, their storage, storage and accounting at the construction site;

- the need for the manufacture and delivery, warehousing, storage and accounting of framing blocks of slats of wood or plastic.

The task to which the proposed utility model is directed is to simplify the design of the block, reduce the laboriousness of construction, delivery, storage and accounting of component parts.

The technical result from the use of the utility model is the simplification of construction technology, the exclusion of the organization of the mortar assembly at the construction site, the construction site is reduced to the installation of blocks, and, finally, the decrease in the category of masons.

The aforementioned task is achieved in that the blocks for masonry walls are made by one of the known methods from a sand-cement wall with a ratio of ingredients from 5: 1 to 2: 1, preferably 3: 1. On the upper bed plane symmetrically and evenly along the length of the block, in the vertical axial plane, protrusions are made, and in the lower bed plane - corresponding to the protrusions - depressions. The protrusions and depressions are in the form of truncated cones, the diameter of the larger base of the depressions is half the thickness of the block, and the depth is one quarter of the thickness. The diameter of the larger base of the protrusion and its height is less than the corresponding diameter and depth of the cavity by 3 to 7 mm.

In the drawing, a fragment of a wall made of the proposed blocks is schematically shown in FIG. 1, and in FIG. 2 is a block in isometric view with a section along AA (FIG. 2), where the bonded face is 1; upper bed - 2; ledge - 3; spoon face - 4; depression - 5; lower bed plane - 6; figure 3 - connection of the blocks of the upper and lower rows.

The laying of wall blocks is as follows.

After isolation and a layer of mortar, a number of blocks are laid on an equal surface of the foundation. Blocks of the following row are installed on them: strictly bonded to bonded with ligation of vertical joints, i.e. with an offset of half a block relative to the previous row, and the entire masonry is reduced to laying the upper blocks on the lower ones with the combination at the upper block of the cavity - 5 on the lower bed plane - 6 with projections - 3 on the upper plane - 2 at the lower row. As a result of this, the blocks self-fix in the design position.

Claims (1)

A block for non-solvent masonry in the form of a rectangular parallelepiped having truncated cone-shaped cavities on one of the bed faces located symmetrically along the length of the block in the mid-vertical plane, characterized in that the large base of the cavities have a diameter equal to half and a depth equal to a quarter of the thickness block, and on the second bed face in the same median vertical plane equidistant to the depressions there are protrusions in the form of truncated cones, the diameters of their bases and heights being less than 3-7 m than the depressions m
