Houses made of wood-concrete panels: the characteristics of the material, the actual construction experience

In today's market there is not only a great variety of technologies, allowing to build people with different levels of income, but also the mass of material - reduces the cost and accelerates the process. If the recent past, total leadership kept brick, today broke forward various blocks and even plates. One of the most interesting materials, actively gaining market - wood-concrete panels, which do build houses and portal users FORUMHOUSE.

Wood-concrete panel - raw materials, characteristics

Arbalitovye panel - versatile, environmentally friendly building material, belonging to the group of lightweight concrete.

Like the more common wood-concrete blocks, the wall material is made from recycled materials - wood industry waste (wood chips) and a binder - cement. There may be a small proportion of other plant materials (hay, hemp meal). wood processing provides fire retardants plates, and water repellents and antiseptics prevent putrefaction processes and reduce the hygroscopicity of the material.

During the processing of wood chips is converted into acicular homogeneous mass is mixed with the remaining components and loaded into molds where compacted and pressed by means of vibration. Characteristically, the exposure time of the vibratory press the workpiece 20 seconds - much less than the duration of other molding of lightweight concrete. If the processing time is increased, a binder and a filler can be divided into fractions - cement will settle and fall characteristics of the plates. Pressed plates extend for several days in a room with a certain humidity and temperature, to gain grade strength.

Finished wood-concrete slab acquires a number of impressive features:

• Reduced thermal conductivity - about 0.09 W / (m * C);
• High density - 700 kg / mᶟ;
• Frost resistance - 25 cycles;
• Durability - M25;
• Flexibility - at the expense of wood filler;
• Environmentally friendly - natural components, concentration of chemical additives is negligible;
• Versatility - suitable for the erection of single-storey houses and low-rise residential buildings.

Wood-concrete panels for external walls are manufactured with the facing layer - cement-sand plaster thickness of 1.5 cm, which greatly simplifies external finish.

Smooth, impervious surface to external influences needs no finishing, only topcoat any facade materials. If necessary, the house of the wood-concrete panels can stand for several seasons in draft form until the owners do not have funds to finish.

In addition to high performance, the wall panels of arbolita have another advantage - speed erecting the box exceeds a similar process even when compared with the large-size blocks and permanent formwork. The manufacturer produces multiple configurations of wall elements, of which the box is mounted without any additional manipulation. When ordering the material well-calculated number of all segments.

• Large slab - main Wall Surface: 230h118h30-40 cm or 229x118x28 cm (height / length / thickness);
• Thin panels - doborka, upper lintel (230h60h30-40 cm or 229x58x28 cm);
• Panel under the window - 80x118x30-40 cm and 80x60x30 cm, 81x118x28 cm and 81x58x28 cm.
• Private unit of bridge - 58x178x28 cm;
• Reinforced of bridge unit - 58x238x28 cm.

Size and equipment differ depending on the manufacturer, but all characterized by the presence of plates connecting the system slot, eliminating cold bridges. Since working with plates made using lifting equipment, each reinforcing loop fasteners are available.

rack mounting technology

Lite weight plates makes it possible to save on the foundation, permitting the level of groundwater and soil composition. Most often under the wood-concrete slab do melkozaglublenny strip foundation (MZLF). Base width correlated to the width of the panels - 30 or 40 cm, because the brick wall in the sense not. Participant Portal of Kazan, near which is one of the country's leading production boards arbolita - sabirkaTogether with the husband stopped exactly on MZFL 30 cm thick. However, they have perfected the substrate with a truck tires used in an amount of 56 pieces.

Due to increased wall rubber footprint on the ground and increased the depth of the foundation, but reduced height tape and solution flow. Under the tires were dug trenches, laid geotextile. After laying a tire outer wall and an inner support (tape) was backfilled and compacted enriched sand-gravel mixture. And on this layer blanketed sealing layer (roofing), was mounted wooden formwork, laying the pipes under communication knit reinforcing cage and the solution was poured. To the formwork is not twisted, it pulled the pins, for pouring concrete hired. Based immediately were formed grooves for laying wooden lag overlap. The height of the tape with the plinth part was 0.8 meters.

sabirka (Participant FORUMHOUSE):

The first house built for a family of six people: father, mother, four kids, same age. He turned slightly unusual, starting from the foundation and finishing the look. We decided to experiment in full.

A participant for wood-concrete portal Vetkasireni plate-rostverkovy chosen pile foundation, due to the composition of the soil, groundwater level and height differences in the area of ​​0.65 meters. All calculations are done with her husband, based on information from our portal, regulations and the expected load on the structure.

Vetkasireni (Participant FORUMHOUSE):

Thought, read, consulted, think again and again read. We have decided that the foundation would be pile-rostverkovym. And if the decision is made, and agree with both of them, then it is hard to convince us.

Piles extension under the "heel", diameter 25 cm, height 50 cm to 120 cm, the reinforcing cage of rod 14 mm and 6 mm, for filling piles adapted bucket without a bottom, which greatly facilitate and accelerate the process. Issues of reinforcement piles subsequently welded to the frame of the foundation Lena used fittings of the same diameter. Although when installing the formwork and during pouring and compaction of the solution sought sustain level after checking frozen base it revealed that turned bias that decided to withdraw brick. To slabs lay perfectly flat, waterproofing laid in two layers.

project slabs must be ordered from the manufacturer or dealer. If the region does not allow the purchase directly, there usually offer services installers.

Widespread practice - the simultaneous delivery of material to the site, unloading and assembling the frame, which have teams of professionals takes less than a day for the construction of one floor.

With such rates can not be compared any other material, which adds to the popularity of the plates arbolita. And the speed - not a gimmick, but a reality, confirmed by our skilled craftsmen.

sabirka:

We started at nine in the morning, and began to grow on the walls of our eyes. An impressive spectacle, I must say, especially for people like me, bustler - can not stand the slowness in anything. While her husband filed a bucket with a solution to fill the slots, performing work worker, we admired the children how to collect our home-constructor. Six hours later, we paid off with a crane, and the guys-fitters, snack pilaf and drinking tea, went home.

Vetkasireni:

By eight crane arrived and work started - well done guys, worked quickly and smoothly, the plates are aligned wedges, once sawed notch Laying nets, the slots were filled with a solution. The box was collected by six in the evening.

To reduce heat loss through the joints in the frame are not filled with the usual cement-sand mortar, and opilkobeton. To increase the plasticity are used as special additives, and various detergents. Although the involvement of mounting crew requires additional expenses, box, collected the day, compensate for spending.

Depending on the project, the internal load-bearing walls can be also wood-concrete or other materials. sabirka with her husband planned second floor, so the support of silicate bricks laid. Vetkasireni spouse treated with plates, as the house of one floor and did not require reinforced bearing walls.

To tie together the design and increase the strength of the building, on the surface around the perimeter of the concrete poured Laying nets. Floor house, he will become the basis for rafter system for the second floor will be supported under the slab or lags ceiling and walls of the plates, the assembly of which is similar to the first floor after the final maturation Laying nets.

The key to quiet the assembly process is elaborate and a calculated project. Online Manufacturers plates have algorithms for calculating the wall in cubic meters. A lot of interesting ideas, practical advice and innovative solutions can be found at FORUMHOUSE portal.
