Summary

This graduation qualification work was developed on the basis of a previously issued task by the Department of Reinforced Concrete and Stone Structures, the theme of this work is: "Universal Production Workshop in the City of Chita."

In accordance with the issued task, a project was developed for the construction of a specialized rebar workshop with landscaping and landscaping of the adjacent territory.

The architectural and construction part includes the development of a master plan and its further development in terms of landscaping and landscaping. This section works out the plan of the production workshop, cross-section and longitudinal sections, heat engineering calculation of the enclosing structure, as well as the facades of the building with a color solution.

The design and construction part includes the design of a prefabricated reinforced concrete column, a rafter structure (a spray-free truss), a monolithic glass-type foundation.

The organizational and technological section includes the development of an object construction plan for the construction of a production workshop and its commissioning.

The section deals with the issue of providing employees of the basic enterprise with personal protective equipment and the procedure for providing and testing personal protective equipment.

Introduction

The one-story industrial building is most often made of framed reinforced concrete. The frame perceives the loads acting on the building: vertical (weight of coating and snow, loads from bridge cranes and overhead equipment) and horizontal (forces from cranes braking, wind pressure, seismic impacts, etc.). The frame is assembled from individual elements according to a rack-and-beam scheme, which consists of posts (columns), girders, coating plates and stiffening links.

Structures covering the span are called rafters. In this case, these are frictionless trusses, and ribbed coating plates are supported on them. The frame must be rigid, i.e. have sufficient spatial rigidity in the transverse and longitudinal directions. Transverse stiffness is ensured by transverse frames consisting of columns rigidly pinched in foundations and girders hingedly supported on them. The role of girders is performed by rafters - raceless trusses.

Longitudinal frame stiffness is provided by longitudinal frames, which consist of the same posts (columns) rigidly pinched in foundations, and hingedly supported girders. The role of girders is performed by ribbed coating plates and longitudinal structures, or only longitudinal structures. Rafter structures shall be protected from overturning, which is ensured by welding of their supporting embedded parts to embedded parts of columns, and at height on the support more than 900 mm - by installation of additional vertical connections at the ends of rafter structures.

Stiffness of longitudinal frames is less than stiffness of transverse ones, since moments of inertia of sections of columns in longitudinal direction are less than in transverse direction. Therefore, at the height of the building (from the floor to the bottom of the rafter structure) H > 9.6 m without cranes and at any height H with bridge cranes between the columns, longitudinal vertical connections are established.

The stiffness of the framework is increased by welding the coating plates at least at three points to the underlying structures (through embedded parts). The three anchoring points form the vertices of the geometrically unchanged triangle figure, i.e., create a rigid horizontal connection, and all the plates together create a horizontal hard disk that allows the transverse and longitudinal frames to work together. To this end, the gaps between the slabs are ground with concrete.

Buildings are divided into temperature compartments (blocks), the length of which is determined by a special calculation and depends mainly on the seasonal temperature difference.
