Introduction

Construction is one of the main areas of human production. Over the past decade, Russia has been developing various branches of human activity, and this also applies to the construction industry. The architectural and artistic appearance of the building is not of the least importance. Over the past few years, the industry has made a big step forward in the development of building materials and products.

In the mid-1990s, the situation in the country was not easy, which invariably affected the economy and demographic situation in Russia. Currently, the Government of the Russian Federation is actively developing projects related to the construction of preschool institutions. At the beginning of this year alone, 9 billion rubles were allocated from the federal budget for their development.

Currently, projects are being implemented in the country that make it possible to provide the residents of the country with additional places in preschool institutions with the least costs - the opening of full-day preschool groups .

It would also be worth noting the importance of measures that were aimed at the development of secondary educational institutions .

Many different programs have been developed in recent years, which are already giving their results on the development of demographic growth in the country.

In connection with the current situation in Russia, this topic is one of the most relevant today and the next few years in general.

On the site, children's playgrounds are designed, on which there are small architectural forms. The size of small forms of architecture on playgrounds is designed taking into account the age of children. When designing the site, the method of placing groups of trees and flower beds in such a way that each site is autonomous and has a green hedge is used. There are two entrances to the site.

Landscaping.

The lawn is arranged by sowing perennial grasses along a layer of plant soil. Before the start of construction, the existing soil is cut and stored in reserve. After erection, this soil is used in landscaping.

Structural solutions of the building

1.4.1 Structural diagram and structural elements of the building

The kindergarten is a two-story building with bearing external and internal brick walls, with a partially used basement and attic.

General stability and spatial rigidity of the building is provided by external and internal mutually intersecting load-bearing brick walls and slab discs.

The external walls of the technical floor and the basement below the ground surface are made of foundation concrete blocks of FBS as per GOST 13579-78 on cement sand mortar M50 and of ceramic ordinary full-white brick of the grade KORPo 1NF/100/2.0/35 GOST 5302007 on cement mortar M100. The walls of the basement, the technical floor on the ground side are insulated with extruded polystyrene foam.

The external walls of the technical floor and basement above the ground are three-layer: a load-bearing layer of ordinary clay brick according to GOST 53095 on M100 cement mortar; mineral wool slabs insulation on synthetic binder GOST 2188076; facing layer of concrete stone 6 K8.12 as per TU 5741003439729952000.

The external walls above the elevation of 0.000 are three-layer: a load-bearing layer of ordinary clay brick according to GOST 53095 with a thickness of 510 mm on M75 cement sand; mineral wool slabs insulation on synthetic binder GOST 2188076; facing layer of ceramic hollow brick.

The external walls of the attic are three-layer: a load-bearing layer of ordinary clay brick according to GOST 53095 on M100 cement mortar; mineral wool slabs insulation on synthetic binder GOST 2188076; facing layer of ceramic hollow brick.

Brick facing layer is attached to the load-bearing wall

flexible connections made of fiberglass reinforcement 700mm long. Connections are installed in masonry welds with a pitch of 450mm horizontally and 600mm vertically (4pcs/m2).

For the brick cladding device, a monolithic expanded concrete belt with a thickness of 140 mm is made at the level of the basement floor.

Internal walls made of ceramic full-white brick KORPo 1NF/100/2.0/35 GOST 5302007 on M75 cement mortar.

Partitions made of ceramic full-white brick KORPo 1NF/100/2.0/35 GOST 5302007 on solution M50 and from blocks of cellular concrete Y = 700 kg/m3.

Jumpers - prefabricated reinforced concrete, according to the series 1.038.1-1 issue 1.

Slabs are made of prefabricated reinforced concrete multistage slabs according to the 1.1411 series. 60, 63 of various lengths and widths with careful grouting of joints, arrangement of monolithic closures and sections, which ensures rigidity of slab disks.

The internal staircase is made of reinforced concrete steps as per GOST 8717.184 for metal stairs.

External metal ladders from the rolling profile.

Foundations for the building are provided in the form of monolithic pedestals along the pile base.

The roof is pitched along wooden rafters with a roof steel coating on a continuous flooring.

Insulation in the attic floor - rigid mineral wool plates URSA, 370 mm thick.

Organization of works on pile field arrangement

Driving is the main method of submerging finished piles. For clogging, special installations are used - copra, on a self-propelled (based on tractors and cars) or tracked (based on an excavator) track.

Preparatory works include: site clearance and layout; breakdown of piles position, arrangement of linings and ways of copra movement, pile delivery and storage, equipment delivery; equipment of lighting of the site and workplaces; test driving, based on the results of which the driving schemes and the piling project are corrected.

Piling is carried out until the failure specified by the design is received.

Failure - pile diving depth from one impact. Failure is measured with accuracy up to 1 mm. The draught from one impact at the end of pile driving is difficult to measure, so refusal is defined as the average value in a series of impacts called collateral.

When piles are submerged with diesel hammers and single-action steam-air hammers, the pledge is accepted as equal to 10 blows, when piles are submerged with double-action hammers and vibration loaders, the pledge is accepted as equal to the number of blows per 1 minute of clogging.

The pile diving process consists of the following operations:

- pulling and lifting the pile with simultaneous installation of its head part in the head seat in the lower part of the hammer;

- installation of pile in guides in the place of driving;

- piling first with several light blows with subsequent increase of impact force to maximum;

- movement of the lump unit and cutting of the pile according to the specified elevation.

The top of reinforced concrete piles is cut down with a bump hammer, reinforcement

is cut by gas cutting.

There are the following main schemes for driving ordinary piles,

sectional and two spiral (from the edges to the middle under normal conditions, from the middle to the edges with dense soil).

Organization of work on the pedestal device

The purpose of pedestals is to combine individual piles into a common pile foundation. Pedestals are monolithic and prefabricated monolithic of various heights and shapes. Monolithic pedestals have different shapes - square, rectangular, triangular and tape, depending on the design of buildings and structures, geological conditions, type and number of piles. In case of driven piles, whose heads are often at different elevations, labor-intensive operations are carried out before the construction of the pile pile head (cut down concrete, cut rebar, etc.) The pedestal in the formwork is concreted. The concrete mixture shall be laid in horizontal layers evenly over the whole area of the pile. Concrete mixture is transported by self-propelled concrete laying or buckets with opening bottom transported by crane. The concrete mixture is compacted with vibrators.

Quality control of works

When monitoring the position of piles in the plan, make sure that the permissible deviations are not exceeded: 0.2 D - for driven piles with single-row arrangement -

nii; 0.3D - at arrangement of piles in two and three rows in belts and bushes (D - diameter of round or maximum size of rectangular pile). Pile head elevations can have a deviation at a monolithic pile cap of 50 mm, at a prefabricated pile cap of 30 mm. During installation of the reinforced concrete pile, the following operations are monitored: installation and installation of the formwork (deviation from the vertical should not exceed 5 mm by 1 m of height), installation of reinforcement, (deviation from the design distance between the rods should not exceed 5 mm), concreting of the pile (Deviation from the horizontal

the surface of the concreted pile shall not exceed ± 20 mm).
