Summary

This diploma project consists of a graphic part and an explanatory note.

The Explanatory Note includes a project note that covers the following sections: general architectural and construction design; design of building structures; design of the task list; environmental protection.

In the architectural and construction part, a master plan has been developed, which includes the main objects, elements of improvement and landscaping.

When designing building structures, the following versions of the structural framework of the building are considered:

- load-bearing structures on the basis of the prefabricated framework, according to the produced series 1.0201/87;

- bearing structures based on "Cheboksary series" products;

- load-bearing structures on the basis of a frame made of monolithic reinforced concrete.

Based on the technical and economic indicators, the most economical option was chosen.

Safety and environmental measures have been developed.

Variant Design

1.1 Description of options

Three types of design solutions are proposed for variant design. All presented versions are made of monolithic reinforced concrete. The difference between these options lies in the different type of slabs and the type of structural structures. In the first version flat beam-free floor with bearing monolithic walls and columns is proposed, in the second version - floor along contour beams with bearing monolithic walls and columns, in the third version - flat beam-free floor with bearing monolithic walls. All three options have the same breakdown network. Columns do not differ in cross-sectional size.

The building is 17 storeys, as well as the basement, where the technical floor is located. The building is heated, has a plan size of 15 m by

61.20 m. There are two elevator halls and an unnamed staircase .

As enclosing structures, brickwork 250 mm thick with a ventilated facade is used.

Concrete class of all structures in all variants is B25.

1.2 Option 1

The layout of the elements of the first version is shown on sheet 1 of mark B (see list of sheets of drawings of the diploma design). As the load-bearing system of the building, a monolithic reinforced concrete frame is used. The spatial rigidity of the building is ensured by the joint work of columns and walls, interconnected by floors and forming a geometrically unchanged system.

Floors - monolithic flat beam-free, 200 mm thick. This type of overlap increases the height of the space in the room.

The columns have cross-sectional dimensions: 400x400 mm. Column Reference - Axial .

Monolithic walls have a thickness of 200 mm.

1.3 Option 2

The layout of the elements of the second version is shown on sheet 2 of mark B (see list of sheets of drawings of the diploma design). The second version is a prefabricated monolithic girder frame of the building. The basis of the prefabricated monolithic technology is a load-bearing frame consisting of three main reinforced concrete elements: vertical support columns, pre-stressed girders and floor slabs. The < colonnaregelplate > connection unit is monolithic. The entire frame is assembled without welding. Plate thickness 60 mm.

The columns have cross-sectional dimensions: 400x400 mm. Column Reference - Axial.

Monolithic walls have a thickness of: 200 mm .

1.4 Option 3

The layout of the elements of the third version is shown on sheet 3 of mark B (see list of sheets of drawings of the diploma design). The spatial rigidity of the building is ensured by the joint work of columns and girders, interconnected by floors and forming a geometrically unchanged system.

Slabs along contour beams have cross-sectional dimensions of beams: 450x200 mm. Plate thickness 220 mm.

The columns have cross-sectional dimensions: 400x400 mm. Column Reference - Axial.

Monolithic walls have a thickness of: 200 mm.

3 MAIN DESIGN

3.1 General data

In this explanatory note, the load-bearing structures of a 17-story residential building with public premises on Petukhova Street in the Kirovsky District were calculated.

Basic data for performance of calculation are architectural plans and cuts of drawings of code DP.ZhBK.461AKZh.

Based on these materials, the building was simulated in the SCAD 11.5 computing complex to determine forces and deformations (deflections and displacements), as well as reinforcement of elements of the building structural system.

The calculation is performed in accordance with the regulatory documents of the Russian Federation:

- SP20.13330.2011 "Loads and impacts" (Updated revision);

- SP521012003 "Concrete and reinforced concrete structures without preliminary reinforcement stress";

- SNiP 52012003 "Concrete and reinforced concrete structures. Basic Provisions ";

Construction conditions

Construction conditions (Novosibirsk, Russian Federation):

- climatic construction area according to SNiP 230199 "Construction climatology" - I V;

- design outside air temperature of coldest days with coverage of 0.92 -minus 39 C °;

- design value of snow cover weight per 1 m2 of horizontal ground surface according to SP 20.13330.20011 "Loads and impacts" (updated version of SNiP 2.01.0785 *) - 240 kg/m2 (IV district);

- standard speed value of wind pressure up to 10 m above the ground surface according to SP 20.13330.20011 "Loads and impacts" (updated version of SNiP 2.01.0785 *) - 38 kg/m2 (III district);

- site seismicity according to SP 14.13330.2011 "Construction in seismic areas" (updated version of SNiP II781 *) - up to 6 points on MSK scale.

Basic Design Solutions

The load-bearing structural system of the monolithic reinforced concrete building includes the following elements:

- cast-in-situ columns with a section of 400x400 mm from BGS B25 concrete, GOST 747394. The pitch of the columns in the longitudinal direction is 4.8; 6; 3; 4,5; 6.3 m and crosswise 6 and 3 m;

- slabs and coating at elev. + 0.000 - + 50.920 non-panning dripless, 200 mm thick, made of monolithic concrete BGS B30 GOST 747394;

- cast-in-situ walls 150 mm thick, concrete BGS B25 GOST 747394;

- enclosing brick walls 250 mm thick with a facade system "Kraspan";

- internal brick walls 120 mm thick;

- foundation slab on natural base, 1300 mm thick from BGS B25 concrete, GOST 747394.

The spatial rigidity and general stability of the building are ensured by the joint operation of the frame columns, the floor disk and the rigidity diaphragms .

Accounting of buildings and structures liability

The level of responsibility according to the "Technical Regulations on the Safety of Buildings and Structures" (Federal Law of 30.12.2009 N 384FZ) is normal.

Design values of forces in elements of building structures of the structure are determined taking into account the safety factor by responsibility adopted - 1.

Construction Organization and Technology

On the basis of the task, it is necessary to develop a process plan for the construction of one floor of a reinforced concrete monolithic frame of a building with a flat floor.

5.2 Basic building parameters

The building is 17 storeys, the first floor is intended for public premises, as well as one basement floor, where the technical floor is located. The building is heated, has dimensions in axes in the plan 61.2 m by 15 m. There are two elevators, an elevator hall, an unnamed staircase .

The layout of the elements of the first version is shown on sheet 1 of mark B (see list of sheets of drawings of the diploma design). As the load-bearing system of the building, a monolithic reinforced concrete frame is used. The transverse and longitudinal rigidity of the building is provided by the monolithic frame of the building.

Floors - monolithic flat beam-free, 200 mm thick. This type of overlap increases the height of the space in the room. Concrete class B30.

Plate columns have cross-sectional dimensions: 400x400 mm. Column Reference - Axial. Concrete class B25.

Monolithic walls have a thickness of 280 mm. Concrete class B25.

As enclosing structures, brickwork 250 mm thick with classical plaster is used.

5.5 Selection of work methods

Before starting work on the construction of the framework of a monolithic building, it is necessary to equip additional warehouses (for reinforcement products, for formwork), equip places for receiving concrete mixture.

To erect the framework of a monolithic building, we use a universal inventory disassembling - rearranged formwork. The formwork is supplied by the crane, and the installation is carried out manually.

All reinforcement products are supplied by crane. Installation of all rebar products is performed manually.

Transportation of concrete mixture is carried out by concrete mixers from the nearest solution - concrete assembly, which allows to preserve homogeneity and necessary mobility of concrete mixture.

The following concrete mixture supply schemes are possible in the structure: cranes in bays; Motor concrete pumps.

The formwork is disassembled manually. The formwork is supplied to the ground using a crane. On the ground, the formwork is cleaned, lubricated, checked and then used in the next cycle.

Accessories for concrete works are accepted based on concreting intensity, which is determined based on the time norm for concrete mix laying by concreters.

Option 1.

For unloading of reinforcement, formwork and further supply of reinforcement products, formwork and necessary construction products and equipment, an attachment tower crane is used.

The concrete mixture is supplied to the place of its laying according to the "crane - badya" scheme. During crane feed, concrete mixture from vehicles is unloaded into rotary buckets, the capacity of which should be a multiple of the intensity of laying the concrete mixture and the capacity of the body of the car carrying the concrete mixture .

Option 2.

For unloading of reinforcement, formwork and further supply of reinforcement products, formwork and necessary construction products and equipment, an attachment tower crane is used.

Concrete mixture is supplied to the place of its laying by means of concrete pump.

5.13 Development of the schedule (schedule) of the complex concreting process of one floor

The work schedule reflects the sequence and organization of the processes in the concrete works complex and conditionally consists of two parts. The first part in the form of a table includes all engineering calculations, and the second - reflects the sequence and duration of work with the indication of the calendar time of the start and end of individual processes, as well as their relationship .

The basis for the construction of the first part is the data of the production calculation and process diagrams, taking into account that machines and people must work throughout the process.

See the concrete work schedule on sheet 3 of grade T.

Fill in the table part of the plan

Column 2 records the processes in the execution sequence. Column 3 shows the units of measure of the type of work specified in each item, the scope of work being measured in physical units - t, m, m2, m3, pcs, 100 m2, 100 t, 1 element, 1 frame. Column 4 shows the number of accepted scope units included in each row. In column 5, the amount of labor of all the processes and works performed by one link from the production calculation is entered with the transfer of labor from person-hour to person-shift (by dividing this amount by 8 hours). After that, the columns (9, 10, 11) characterizing the operation of the machines used in the processes and works listed in the paragraph are filled in. The graphical part of the schedule is made in the form of lines that reflect the duration of work in days or shifts and their relationship.
