One of the priority directions of development of modern civil engineering is the use of new building materials, which qualitatively improve the energy and heat-saving properties of residential buildings. Heat-efficient wall materials, commonly referred to as heat blocks, can provide a comfortable temperature inside the house in the most adverse weather outside the building. The construction of houses from heatblocks attracts developers and construction companies due to the variety of architectural solutions and high speed of erection of structures.
A distinctive feature of a heatblock , compared with traditional stone wall materials, is its low thermal conductivity, providing the necessary thermal protection of residential premises with a minimum wall thickness.
If we compare wall materials by the magnitude of reduced resistance to heat transfer R0, determined in accordance with SP 50. 13330. 2012 "Thermal protection of buildings. Updated version SNiP 23-02-2003", then by its heat-shielding characteristics, the wall is from blocks with a thickness of 30 cm are not inferior to a brick wall with a thickness of 230 cm and a concrete wall - 450 cm.
Such high thermal efficiency of the blocks is provided by a carefully designed unique design, which is a combined three-layer system (like a sandwich) made of ceramic itobetona and polystyrene.
Projects of houses from heatblocks fully meet the basic concept of industrial construction: “Everything is in one”, because each the heatblock layer performs a specific function:
Structurally similar three-layer structure of the heat block is implemented as follows:
In order to prevent possible exfoliation of the wall material due to the physical heterogeneity of expanded polystyrene and expanded clay concrete, all layers of the heat block are fastened together with reinforcing bars made of basalt or fiberglass.
For the manufacture of three-layer heat-efficient wall blocks special matrices are used , providing fixation in a uniform design of all three functional layers of the product. The block is formed in the matrix in the following sequence:
For the layer-by-layer connection and fixation of internal elements, the polystyrene foam liner is equipped with special fasteners (plastic anchors or reinforcing bars).
Many manufacturers prefer to engage the dovetail thorn groove (the spikes and their corresponding grooves are in the form of a trapezoid) to a pin-point connection, which provides a more reliable monolithic system assembly.
The range of heat-efficient wall materials is quite wide. In the projects of houses from heatblocks (a photo of one of the projects is given below), the builders organically combine the multifunctionality of wall blocks with the possibility of erecting buildings in any architectural style without additional lining.
Heatblocks are classified according to the following main features:
Also, heat-efficient blocks have different strength indices depending on the brand of claydite used and differ in the material of the heat insulating layer.
When discussing the advantages and disadvantages of houses from heatblocks, the owners' reviews accentuated the following positive factors :
Heating costs for residential premises in winter time for a house from heatblocks is 3-3.5 times lower compared to a brick house of a similar layout.
Additional advantages of heat-efficient block materials are the advantages that distinguish the technology of building a house from heatblocks from building a stone house according to traditional technologies:
Of the drawbacks, the heatblock differs in the following moments :
Building a residential house from wall heat-efficient blocks are carried out according to the following algorithm:
Each stage of construction with the use of blocks has its own characteristics that distinguish it from the technology of building houses from traditional materials - brick, concrete or wood.
The strip foundation is a foundation in the form of a single concrete strip running along the perimeter of the building and under its supporting walls.
In the Russian market of building materials, heatblocks are offered in the form that does not require additional painting or finishing. Changing the texture or color of the heat block is performed at the request of the home owner using brushes, rollers or spray guns. The most popular finish inside the walls of the house. In such cases, a reinforcing mesh is used to prevent peeling of the stucco applied to the wall.
Organizations engaged in the design and construction of houses from turnkey heatblocks determine the price of their services depending on the number of floors of a residential building and the amount of work. In the catalogs, construction companies usually give two prices - a set of wall products separately and the total cost of building a house.For example, the cost of a set of heatblocks for a one-story house with a total area of 86 m 2 is almost 300 thousand rubles, while the construction of such a house on a turnkey basis is estimated at 1,550 thousand rubles. For a preliminary assessment of the value of the house for which thermoblocks are applied, the price per 1 m2 of the building area varies from 15 to 20 thousand rubles.
The intensive nature of modern construction opens up a broad perspective for technologies with wall heat-efficient units, since recently when ordering the construction of a country house more attention is paid to the timing of the order and issues effective energy saving. In such cases, the use of heatblocks will be more preferable in comparison with traditional building materials.
