House of aerated concrete with a pent roof on his own project

Despite the raging debate between supporters and opponents, one of the most popular masonry aerated concrete blocks are considered today. That Swift099, having decided to build his house, stopped for gas concrete, and the experience of its construction will be useful to those who also has limited resources, but decided to be built.

House: single-pitch roof, GB, 145 m², for 7.5 months

Sooner or later, almost everyone gets to the need to expand living space and one option - to take a mortgage for the construction of his house, not to buy a larger area of ​​the apartment. And I enrolled member of our portal with the nickname Swift099, The embodiment of his project began in March last year. He wanted to meet with the current year have already increased the family under the lights in front of the crackling fireplace.

Swift099 (User FORUMHOUSE):

Built a house for his project of concrete blocks - after 7.5 months entered in a fully decorated first floor. Thread open to share building experience with limited resources - for mortgage means and under conditions of constant employment.

The goal was to meet the estimate of 2.2 million rubles, and the terms dictated by the replenishment of expectation, with two children in a studio apartment, "not convenient".

Design

To speed up the process of construction of the box, Swift099 carefully prepared: has mastered a program for self-design (ArchiCAD) and developed his project. From the model refused, as it meets all the needs not choose. The development and fine-tuning, which includes all critical calculations (load, bridge, flooring, roofing system, network engineering) took about a year. The result was a two-storey house project area of ​​145 m² with a pent roof, of the aerated concrete blocks D500 mark (400 mm), without additional insulation.

Design project:

Foundation

Not only the design has been made in advance, but also the basis of the house - UWB with a cellar, filled in the summer of the year 2015, again on the basis of precise calculations and in accordance with the weight of the house (about 250 tons). Soil composition:

• topsoil - 0.4 m;
• Sand - 1.2 m;
• loam.

The ground water level low - on the neighboring portion in geological investigations revealed no water even at a depth of 2.5 meters. Nevertheless, Swift099 err and I decided in the cellar immediately lay sump - pit depth of 0.5 m and dimensions of 0.7 × 0.7 m, backfilled with gravel, in the farthest corner. Sump useful unexpectedly quickly. Dimensions cellar tied to the dimensions of plates DSPs used as formwork - 3.2 × 2.6 m and 1.84 m height.

Foundation plan:

First we made markup description via hired equipment (JCB) removed topsoil, a pit dug under the cellar and the trench for supply of water thereto from the well. The cellar in the future will house cleaning equipment. Another trench - to supply water to the bath. The bottom cellar leveled sand lay a dense geotextile, another layer of compacted sand 15 cm, geotextile layer of gravel again and 10 cm. Permanent formwork from DSP 10 mm thick, a small portion without formwork is filled with concrete.

The next stage of the perimeter covered mastic asphalt in two layers on top of it - roll fusion waterproofing (took eight ten-meter rolls). Insulation effectiveness and timeliness of the drain recess confirmed heavy rains - on his return from a short holiday Swift099 found in the cellar of the pond, the depth of 30 cm, which was quickly eradicated thanks to the sump.

Further sheets laid on top of the reinforcement mesh 10 mm, with cell 200 × 200 mm, and a layer of poured concrete thickness of 15 cm. After setting collected from an inner wooden shuttering plank 150 × 40 mm, zaarmirovali same manner and brought HDPE pipe for engineering systems by preparing all to fill.

Despite the low water table, the user has equipped drainage system, which will work more as livnevki - bedding gravel, pipes in the geotextile with the conclusion in the suction well.

The thickness of the sand under the slab preparation - from 50 to 60 cm, for backfilling required 125 tons, an ideal "mirror" to achieve tamper failed, but it turned out quite smoothly. Prepared surface lay a polyethylene film (120 microns), and installed the shuttering boards laid extruded polystyrene. To create a uniform protective layer of reinforcement cage installed on the special plastic clips.

Reinforcement top layer made of expanded polystyrene reinforced fittings - F8, mesh with the cell 300 × 300 mm, the perimeter length of 1200 mm. In the zone above the cellar floor reinforced reinforcement 12 mm. On the layout of floor heating highway alone at Swift099 It took two days and two bays XLPE tubes, each with 240 meters. A total of six loops, length of 65 to 79 meters, clamps 150 × 30 mm. During the rains, and the collector had to hide the tent to connect the pipes. After assembly, the compression system air method - a pair of adapters, pressure gauge, a simple automotive compressor and a hose from the mixer. Before filling put beacons - used for drywall ceiling profile.

Concrete pouring for the brand M350 (B25, F150) - 14 m³, thanks to free access poured directly out of the car, in the process of moving several times from place to place. Porch left nedolitym as concrete a little bit is not enough, instead of the expected surplus. A few hours later the plate jammed "helicopter", changing the snap - first pass - drive, final - blades. Nipped plate defended the film.

The cost of materials, equipment and services of hired workers was 415 thousand rubles, or 4,300 / m² with a basement.

The construction of the box

Preparation for construction of houses Swift099 It began in January a drilling (39 m). The next step, clearing driveways and storage areas of snow, has delivered basic materials. In order not to spend money on tap twice, once delivered and rubble from the floor slabs, and I-beams and rebar, and concrete blocks. Some difficulties arose with the selection of the construction team.

Swift099:

It was difficult to find a builder for the construction of the box - toured the facilities, measured the wall rules, asked neighbors, several teams in the search process have disappeared. As a result, focused on Russian boys, the project is fully discussed, voiced prices for all nodes and considered the final amount. About 220 thousand rubles - a box with an overlap with the reinforcement of masonry in every two rows of valves 10 mm.

Cellar proved very useful to locate the brigade and in late March construction began. First, purified plate from snow and ice, since the stacking blocks.

Such a powerful reinforcement of masonry due to the need - after scaling constructive foundation slab with the help of experienced members of the forum proved that the load - the maximum allowable, and the need to strengthen design. When the mass advantages aerated "famous" fragility and problems with the slightest foundation fraught cracking box. So we decided not to take risks, and insure. The process of construction was under constant supervision - in the evenings after work and on weekends, to eventually projected no different from building, is required to verify compliance with the size and level planes.

Jumpers over the windows coincided with the eleventh nearby, reinforcement calculations, ceilings and roofs of the user ordered professionals. For window span of 237.5 mm four reinforcement rod 12 mm across the bottom and two on top, every 15 cm - crossmember (from edge 10 cm). Decking of the board, with the façade insulation Epps (100 mm).

Next was Laying nets, from the facade of the layers are to the inner wall:

• permanent formwork - 100 mm thick aerated concrete;
• insulation - Epps 50 mm thick;
• basis - 250 mm thick concrete;
• removable formwork - a board thickness of 32 mm.

Armature 12 mm four rod casting solution with addition samomesnym special modifiers, To fill the day had gone. After a week and a half caused a crane and put slabs. To save on unloading immediately brought 9 m³ of lumber for the roof system. And jumpers, Laying nets, and a few days after pouring copiously wetted, with the formwork jumpers took off in a month.

In early May, he started the second floor, and there was a need for a ladder. design parameters Swift099 calculated in the online calculator.

From shaped tube 100 × 100 mm using a rented disc saws and the welding machine he cooked spans. Cutting under the steps ordered in the profile of the company.

The overlap between the floors of slabs - 160 mm thickness, only the balcony area remote wooden beams 150 × 100 mm.

Roof

Mounted in a month - pent, basalt wool insulation of 200 mm thickness, as the user has selected the roofing membrane made of PVC. Typically, this material is used on public buildings and less in demand in the private sector, but Swift099 I pleased with our choice.

Swift099:

Very interesting stuff, while not a bit sorry for his choice, especially like the noise of rain on the roof - no ringing, muffled nice, to the point of hearing the sound.

Preparing the ground under the membrane as a soft tile: needs a solid floor, plus as a substrate is placed on top of the thick geotextile.

Those who are interested in such a roofing experienced forumchane advised to take the web thickness 1.5 mm.

In order not to waste time on the device substrate, can be purchased with pre-pasted from the inside fleece.

trim

Even in the pouring Laying nets were installed under the highway mortgage supply and exhaust recuperation system. Judging by the condition of the filter at the time of a periodic six-month service, the air is clearly in need of cleaning, and the system has been chosen correctly.

Everyone who is going to be built or already in the process of internal finishing works, Swift099 advises necessarily pictures of concealed wiring after hard to remember exactly where wires pass.

Winter and frost below -30⁰S revealed problems in roofing cake - where the heat loss, apparently due to cracks under mauerlat began to form frost. It was necessary to add 100 mm insulation on the outside and 50 mm inside.

As planned, the new home was celebrated after seven and a half months after the start of construction is already in the expanded format, with two kids. Despite some imperfections, the ground floor was ready to accept tenants.

And next to the fireplace to warm the whole family can be.

Facade, parking, blind area

With the advent of a new construction season came the facade decoration. We decided to do not only with no additional warming, but without the rough plaster.

Swift099:

I did not plastered walls on beacons - is too expensive and not entirely justified. Cost of glass-fiber reinforcement. The first reinforcing layer applied to the base mesh schelochnostoykoy 180 kg / m² and two glue layers. After - decorative textured plaster "bark." Yes, lateral illumination noticeable flaws, but it's not for long and unless specifically look closely.

The plans - oblitsevat stone entrance area and a bay window, and decorate accent areas beveled plankenom larch.

Entry / parking area the user chose not to concrete - chosen ground, stamped surface vibratory plates, we lay a geotextile set curbs and filled gravel layer thickness of 15 to 18 cm.

Otmostka be insulated - 30 mm Epps, top mesh cell 250 × 250 mm armature 8 mm. As a finishing layer - rough concrete and paper, first Swift099 8 cm filled base thereon are 4 cm colored solution, after setting a forms printed pattern.

To the balcony and the entrance was warm and dry, completed glazing.

participants in the discussion are also plans to build on the bank's funds, were interested that had the loan.

Swift099:

The foundation I had already built 2.4 million, I moved to a fully finished ground floor.

A lot or a little, everyone decides for himself, Swift099 I set a specific goal and its made - children grow up not in a studio apartment, and in the comfort of home.
