Welcome!! the guru of building frame structures!.I decided to enroll in your ranks and to build myself a half or a (semi-) construction, which will be called as a service building.
The size of the planned house is about 7950 *3670 (chosen from the needs and the opportunities with regard to the size of the sheet materials and its minimization of cutting).
The sesrvie building will have on the ground floor:
* a room
* an entrance hall, and a kitchen
* a combined bathroom (shower, WC)
And in the attic space there will be kind of 2-bedrooms
.
The layout of the 1st floor in the miniatures.
All internal walls are slight and aren’t supporting. Only the perimeter will carry - the outer walls, and, basically, as I understand it, the two long walls, because there will no load-bearing columns inside.
The construction will be built on the hillside, across the slope (the facade to the street, the slope to the pond, the pond is about 80 meters).
The map of the height drop in the corners of the building lokks as follows (from the pond to the street):
-60 -20
-400
The soil – a chernozem about 1 meter and then it smoothly passes into something of a clay and a sand. There is no water of 2-d metres depth. I make hole on November last year. But everything is dry and comfort.
Based on the received information from the Internet and books, there were decided to make the foundation columnar with a grillage of 150x150. It was necessary to fast the timber on the posts by putting the vertical axis on the pin of each column without screwing by the nut (in the case of discrepancy of columns in the vertical axis, so that you can equalize the height by the pads, just in case, for short). The tape has disappeared because of the significant inclines.
The layout of the foundation and their parameters in miniature.
Then I ‘am planning to tie the perimeter by the board of 150*50, floor beams. The flooring is - OSB-3, a thickness of 18mm. The bottom hem is OSB-3, 10 mm. Inside, as expected, the layers and a glass wool “Isover”, a layer of 200 mm.
The scheme of arrangement of the floor in in miniature. (only the frame and the upper deck).
Then I continue to design...
That's a lot of thought about all this:
1. The mass of the building (excluding the mass of the foundation pillars), about 7-8 tons, I take a technological reserve of 25% - 2 tons + a snow load from the roof with a slope of 50 degrees to the horizon - 3.2 tons (61 sq. m. * 180 * (60 -50) / 35). Total, "the peak" mass of this “joy” will be almost 13-14 tons.
2. The support area of my posts: 45 * 45 * 12 pieces = 24 300 square centimeters. The undercutting ground support of the pillar I accept as 1.2 meters (you never know, will it suddenly become swollen or crawl slowly the upper layer). Thus, if we assume the carrying capacity of the soil to a minimum - 1 kg / sq cm. having a carrying capacity of the foundation of 24.3 tons.
And now the questions:
1. Whether the foundation is correctly selected and counted?
2. Is it enough the beam of 150 x 150?. I honestly doubt, since the entire burden of the house is 13-14 tonnes, will fall through the walls on it, and it's about a one ton per meter or 0.6 kg per square cm. To be honest when I counted everything, I began to think about a reinforced concrete grillage of posts...
3. Whether the floor beams are laid correctly? The ground joist based on a timber grillage of 10 cm on each side. A cross-section of joists is 200 * 50. The length of the ground joist is 3.57 m. The length of the ground joist is 3.37 m. The step of the ground joist is about 50 cm.
So, there are now these questions, I ask knowledgeable and experienced experts and practitioners to dispel my doubts, or to put on the right path. I would be inordinately grateful!
