Dome house with his own hands

In recent years, dome homes in our country from the category of exotic moved into the category of unusual buildings. Their owners are no longer perceived as developers just decided to stand out among the typical houses, but as people who have made a deliberate choice of such a construction.

But the mass distribution of dome homes are usually interfere with stereotypes and a lack of practical information on the form factor of such facilities. Therefore, we will cover in this article:

What is the difference stratodezichesky dome house from geodetic.
As a self-build dome house.
How to build a dome house without the use of connectors.
How much does the construction of a dome home.

Unlike stratodezicheskogo dome homes from geodetic

Practice shows that people who saw for the first time or to learn about the dome home, often divided into two categories. This is - those who unconditionally accepts this form at home and, note, lifestyle, and those who think like structures fad or, as an option - a house not for permanent residence, and a summer cottage "not like everyone else."

We will not go into detail discussing the advantages and disadvantages of dome homes (and they, as well as any construction technology is), and will focus on practice. So, there is a developer who wants to build a dome house. Where to begin? An excellent example of proper and thorough approach - history portal user with the nickname Rustad.

Rustad (User FORUMHOUSE):

I decided to build a dome house a relatively small area, about 100 square meters. m, near St. Petersburg. Plot goes obliquely. The house will be used mainly in the summer with infrequent winter races. I will build a geodesic dome house on beskonnektornoy technology. Such a structure is an accurate mathematical model. Build it without calculation and the project is impossible, since error when assembling the chassis parts and the manufacture should not exceed 1 mm. If you do not comply with this rule, then the accumulation of stocks frame "go away."

Before we tell you about the nuances of the design and construction of the house shown in the photo below, We answer the question, which is one of the first occurs before any person is conceived to build a dome house.

What is the difference stratodezichesky dome house of geodesic? Without going into a detailed description of the technology say that the key difference lies in the way the construction of the frame.

Stratodezichesky dome elevated from racks, for example, made of curved wooden beams, and the stages of its assembly much like conventional techniques karkasostroeniya.

The peculiarity of this technology - resistance to vertical loads and the ability to use in the construction of standard windows and doors.

geodesic dome erected a little differently. First, the individual sections are produced, for example, in the form of triangles, which then step by step, are joined with each other.

When assembling the edges (sections) of the geodesic dome may be applied a connector connection technology (e.g., with a metal connector).

Or (less common in Russia) beskonnektornaya technology.

Rustad I stopped at the last embodiment, and as we have said above, began with the development of the project.

Rustad:

Build a dome house without a project or something scribbling with a pencil on a piece of paper - a hopeless exercise. On the experience of friends I can say that it is always only leads to one thing - the endless alterations and restructuring of what happened. It is also not a panacea - a project to give to designers.

The designer can draw beautifully, but from the point of view of practice that he has created, often impossible to implement. Design a house should a person with specialized education, but even the engineer can not take into account the position of the buildings on the site regarding the cardinal points, compass rose, dimensions finishing materials. therefore Rustad, being available to two free months, I sat down to design a dome home, and this is what in the end it turned out.

Note that the project during this period was modified several times, taking into account the recommendations of experienced builders, the availability of materials, the characteristics of furniture and making requests of the household.

Stages of the construction of a geodesic dome home

The stage design dome home Rustad He passed to his erection. Immediately give several recommendations of the user relating to the organization of construction.

Rustad:

I wanted to build a house as soon as possible, so attracted assistants - one man, well versed in the peculiarities of the frame construction and the worker. I have to say, yes, it is - the extra costs, but if I had built the house alone, I would have it took 3 summers. In this case, to achieve high-quality work, most likely, would not have succeeded. Because physically impossible to keep the same weight units (frame edges) and thus bonding them to each other. When assembling all the time you have something to pull or fold it back. The second and third pair of hands is vital. Otherwise - the accumulation of errors from one row to another and, as a consequence, "school" with the upper contour.

At the user's words, he supervised the construction and his personal - physical contribution is about 30%. Useful experience and masters (in order to avoid errors) karkasostroitelya. Also assembly circuit speed is significantly increased, since 2 people do the job to 4 times faster than the 1 and 3 persons "crank" the same amount of work will have 8 times.

Therefore, the entire building is divided into a number of successive stages, each of which requires careful monitoring.

1. The construction of the basement under the dome house.

Located on a slope. The inclination angle of about 12 degrees. As foundations Rustad I chose pile-screw. Piling field includes size 24 of piles:

pile diameter - 108 mm;
pile length - 2.5 m.

Piles spun for 2 days, carrying into the night. User notes that, trusting working foreman, he had not marked out pile field.

The result: several piles were not where home sites are located. To correct the error had to weld on the "16 th" channel.

2. frame Manufacturer: ribs, struts and rafters.

For winter wood frame purchased and pre-cut to size the blanks on the miter saw in accordance with the design.

This user took 4 days off.

3. Build a dome home.

Construction of the house began in April. The weather was, to put it mildly, "not lotnaya": the rain, the snow, the wind.

The construction of the dome house began with the installation of the riser (cylindrical base).

Raiser recruited from triangles, so that the house looked like a single unit.

At this stage, the question arose as to make removal a terrace. Spin piles under each lag the user did not want to - we would have one big pile field. It is economically inefficient, and in addition a terrace would look ugly.

Rustad I decided to make the terrace a "balcony" - departure, an extension of the floor of the first floor. It remains to choose the material that will withstand such a load.

Rustad:

When I took up this issue and appealed to the company, I do recommend removal of the H-bonded timber beams. Comparing these beams (OSB wall thickness of 18 mm) withLVL beams, section 51h300 uh, I did not see the special economic benefits in the acquisition of an I-beam, and to doubt the strength and load-bearing capacityLVL beams is not necessary. It and put.

Mounting the joists, they lay a temporary floor boards, as weather conditions do not permit normal.

Next, we started assembling the dome.

On the dome assembly (in the snow, strong wind and rain) took 2 days.

An important caveat: to bond together the edges of the beam and, by using structural screws 6h140 mm.

Unlike conventional self-tapping screws (especially the so-called red-hot "black", which can not withstand dynamic loads and break), constructional screw can be bent into an arc, and he will not burst. A special notching cuts, rather than pushing the fibers of the wood, so the screw can be screwed into a knot or in the edge of the board, and it will not crack.

It screws also stronger than normal, and the head of "star" does not allow the bit to break and cut the edges, which simplifies the screwing.

To assemble one unit of six ribs require 12 units. self-tapping screws.

Utilities - water pipes, electrical cables held in the floor.

Box with electroautomatics also collected in accordance with the project at home and placed in the "basement".

The next stage - lining assembled dome water- and windproof membrane, with mandatory sizing laps special tape. Packing lath under the ventilation gap. Installation of OSP (base under the shingles).

"Pie" dome practically repeats the "pie" roof for installation of a soft roof.

An important caveat: dome lining was made of the patterns (triangles) of OSB-3 sheets, 18 mm thick, with dimensions 1220h2440 mm.

Sheathing nails nailed ershonnymi 6h60 mm.

Rustad:

Such a nail is very well kept. Pull out only with "meat", and he quickly becomes clogged, than turn the screws.

Next: the foundation of the CAP closed carpet backing and all missed mastic asphalt.

By making the outer contour, builders have begun to floor insulation. The floor blew ecowool layer of 30 cm, using for this makeshift garden plant based cleaner and plastic barrels.

After warming the floor lay a moisture resistant sheets SHG (gypsum particleboard) 12 mm thick, placing them in a 2 layer.

Mounting the base, went to the wall insulation. For this purpose, a synthetic nonwoven material (insulation) 5 cm thick, placing it in 3 layers.

Rustad:

With this kind of heater to work with. He is not pricked, not afraid of moisture, light. Only difficult to cut with a knife, it is better to use scissors or a special elektrorezak carpet. And I add: it is better not to put on the heater heavy objects, and do not store the rolls in height. Insulation can not recover its shape after the load is removed. It is better to act on such an algorithm - immediately brought and laid.

Insulate the walls of the frame pulled a vapor barrier and also sewed all the plaster-density wood chipboard, but only 10 mm thick.

At this stage, the house has already bought a finished look. After the erection of walls began installation of engineering systems and finishing processes.

These include the following activities:

We chop the outside shingles.

Raiser sheathed imitation timber.

Canopy closed cell polycarbonate, a 10 mm thick.

Built a ladder.

Begun to furnish the rooms and bathrooms.

Mounted a drainage system and a system of autonomous sanitation.

What is the cost to build a dome house

According to Rustad, its structure to break the stereotype of people living in the village. So unusual, original and memorable looks dome house. People to look at the building, come "to tour" around the region and brought relatives out of town. Moreover, when the structure only began to build, the villagers were at a loss what it will be. Rumors circulated that the user is building an observatory, a library, but the least thought it would be a residential house.

Rustad

When I first thought of building a dome home, then drove on the firms in which they are written on sites that are building similar structures. The conclusion from these visits disappointing - no one really does not build these houses. The goal to "firm" one - to lure the customer and convince him to build a conventional karkasnika. To become a guinea I did not want to, so he took everything into his own hands. Moreover, the house I built on technology malorasprostranonnoy in Russia - beskonnektornogo connection. As I mentioned above - for this building needs at least 1 assistant. The project is required! Tolerance +/- 1-2mm frame members for wood, metal +/- 0.5mm.

The house began to build on 28 April and finished (for final finishing) on June 4th. Total for this time spent 1.6 million rubles., With project cost of 950 thousand. But in this price includes expenses that can not be directly attributed to the "box", or they have changed during the construction phase. It:

Delivery of construction materials (in the distance of 100 km) - 100 thousand. rub.
Purchase and installation of an autonomous sewer system - 70 thousand. rub.
Drilling of the borehole and installing a downhole pump - 80 thousand. rub.
Labor remuneration of workers - 250 thousand. rub.
Construction stairs (in the project provides a cheaper option) - 50 thousand. rub.

Summarizing

Dome homes are becoming more and more fans. Someone wants to build a house for the unusual "wow" -effect. Some like the philosophy of life in a dome home (and it is different from life in a normal cabin). Someone just wants to test themselves and try their hand at construction. Fourth captivating special atmosphere of a large space, speed and relative cheapness of construction and cost-effectiveness (in terms of heating) properly constructed dome home.

Those who are only contemplating the construction of a dome home, and would like to learn more about the project Rustad, and also to ask the builder his question, can get acquainted with the topic dome house on a hillside. V4 D9.4.

On FORUMHOUSE have an article, which tells about the stages of construction unusual stone house with round roof and provides recommendations on how to make a bent truss system for a semi-circular roof and lancet.

Also recommend to watch the video - Round House: stratodezicheskogo dome design and the house-the geosphere, which tells about the nuances of construction of a geodesic dome home.
