FIELD: construction.
SUBSTANCE: invention relates to elements of building structures, namely to volumetric units for sanitary purposes, intended for organization of natural ventilation in residential, social, administrative buildings, as well as to erection of building structures, and can be used in construction of monolithic walls, floors and partition walls of buildings and structures used in various industries, where it is necessary to construction thereof. Ventilation unit is made of whole monolithic concrete and has shape of hollow rectangular parallelepiped, consisting of four walls with fastening elements arranged on them and two internal partitions dividing inner space of unit on main channel and two side satellite channels. As fasteners key groove is used made along perimeter of walls with outer side, parallel to upper cut of ventilation unit for jamming in flooring. Two reinforcement rods are arranged in through holes in upper part of walls and inner partitions. Besides, at least, one of walls is equipped with anchor for fixation of brace to it during installation of ventilation unit. Method of mounting of the ventilation unit includes installation of ventilation units on each other and fixed with help of fasteners to floorings; installation of first (start) ventilation unit at lower flooring before grouting of top floor slab with temporary attachment to brace by means of anchor; assembly of top inter-floor slab formwork; reinforcement of upper plate of inter-floor slab with simultaneous installation of two reinforcement rods in through holes of ventilation unit; closure of rim of ventilation unit with temporary cover to prevent ingress of concrete into inner space of unit; concreting floor plate of upper covering, during which deepening-key to upper part of ventilation unit is filled with concrete mix, and fixation of reinforcement bars in inter-floor slab; formwork, top cover, bracing removal after achievement of set design strength of concrete; installation of above located ventilation unit.
EFFECT: technical result consists in simplifying design of ventilation unit and faster process of construction of multistory buildings.
