Abstract

A building wall block containing a concrete sheath and a core of heat-insulating material placed in it before forming the block, characterized in that the core of polystyrene foam is placed inside a hollow prism of bulk foam.

Description

The utility model relates to the construction materials industry and can be used in the construction of civil and industrial facilities.

Known concrete building block, including the front layer, concrete building layers and a heat-insulating layer located between them, and these building layers are connected by jumpers penetrating the heat-insulating layer and made in the form of metal and plastic rods arranged at an angle in horizontal and vertical planes [1].

The main disadvantage of the known building block is the complex manufacturing technology associated with the separate production of a painted face layer with a chamfer around the perimeter, installation of jumpers (metal and plastic rods) piercing the heat-insulating layer of expanded polystyrene, followed by their placement in a small metal form in strict accordance with accepted the distances between them and one of the horizontal walls of a metal form, the formed two cavities between which are then filled aerated concrete or lightweight aggregate mixture to form concrete construction layers.

The closest to the proposed technical essence is the construction of a building wall block containing a concrete shell and placed in it before molding the core block from a heat-insulating material, the concrete shell is made of two cavities facing each other, preferably rectangular in plan, parts spaced from each other from the longitudinal vertical plane of the block with the formation between the opposite upper and lower edges of the gap filled with thermal insulation between facing each other ionic core material and exceeding between the indicated edges the minimum thickness of at least one of the side walls of the shell parts,

at least one of the parts of the shell in the cross section of the block has a C-shaped, or channel-shaped, or trough-like shape, and the other mirrored at least most of the length of the block the shape of the first part of the shell or corresponds to one of the listed forms [2].

The main disadvantages of such a building block are:

- the complex geometric shape of the core made of heat-insulating material, requiring additional labor and material costs in its manufacture, which can significantly affect the cost of production;

- piece forming of the block in separate small forms leads to an increase in the material consumption of metal molds and equipment, and can also affect the quality and volume of products.

The objective of the utility model is to develop the construction of the building block, which simplifies the manufacturing process and ensures high quality products.

An essential feature is that the building block is made with a core (liner) of polystyrene foam block placed inside the foam concrete shell in the form of a rectangular hollow prism, which simplifies the manufacturing process of the block with high quality products.

The construction of the building block and the manufacturing process is illustrated by drawings, where Fig. 1 shows a diagram of the installation of polystyrene foam blocks and cutting of a foam concrete array into blocks, as well as a general view of the block.

Symbols adopted in the drawings:

1 - core (insert) of polystyrene foam;

2 - foam concrete shell in the form of a rectangular hollow prism;

3 - foam concrete array;

4 - polystyrene foam bars installed in an upright position;

5 - cutting lines of the array in horizontal and vertical planes.

The block consists of a core (insert) of polystyrene foam block 7 and a foam concrete shell in the form of a rectangular hollow prism 2.

The manufacturing process of the proposed building wall blocks is based on the cutting technology for producing blocks from a foam concrete array with a volume of at least 1 m ³ , which ensures a reduction in the material consumption of metal forms and a high quality of products due to the full hardening of foam concrete by maintaining the thermal regime of self-heating during cement hydration in large size insulated metal form (removable formwork) on a metal pallet with a heating system.

The sequence of manufacture of the blocks is as follows: initially, in metallic form with a volume of at least 1 m ^3, in strict accordance with the accepted geometric dimensions of the blocks, polystyrene foam blocks 4 are installed and fixed in the vertical position; then the foam concrete mixture is gradually poured into the mold, filling the gaps between the vertically arranged polystyrene foam bars; as the array hardens to plastic strength at a temperature of 50-70 ° C (usually after 5-6 hours), the form is removed and the array is cut into blocks whose height and sides are determined by the pitch of the cutting string of the cutting complex in horizontal and vertical planes 5; manufactured blocks are transferred to wooden pallets and closed with a thermocap to maintain the thermal regime of self-heating.

The advantages of a building wall block:

- reducing the complexity of manufacturing products with high quality products;

- reduction of material consumption of metal molds for production.
