RU97144U1 - REINFORCED CONCRETE BUILDING FRAME - Google Patents

Abstract

 The reinforced concrete frame of the building, including columns, girders, having along the entire length on each side of the shelf for supporting the floor slabs, characterized in that the columns are made with consoles for installing the crossbars and are equipped with supporting angles installed in the places where the floor slabs adjoin them, forming a rigid connection with embedded parts of their reinforcement, and the crossbars of the crossbars are made of metal corners, rigidly connected to the reinforcement of the crossbars.

Description

The utility model relates to the field of industrial and civil construction, namely to the construction of prefabricated and prefabricated monolithic frames of buildings for various purposes.

Known frame, consisting of prefabricated or monolithic columns of rectangular cross-section and multi-hollow slabs, combined into a single system of monolithic reinforced concrete bearing connecting beams. Crossbars in mutually perpendicular directions are passed through columns and are rigidly connected with the latter in these nodes. For this purpose, through openings with full exposure in these places of the working reinforcement are made in prefabricated columns to the height of the crossbars at the level of the floors. The support of multi-hollow slabs on the bearing crossbars is provided by means of concrete dowels, which are formed in the cavities open at the ends of the plates during the laying of monolithic concrete crossbars. At the ends of multi-hollow slabs, releases of their working reinforcement are provided, placed in monolithic load-bearing crossbars (A.I. Mordich et al., "Unified Open Frame Building System with Flat Ceiling, Series B1.020.1-7", Architecture and Construction No. 6, 1999 Minsk)

This frame does not have the required adaptability due to the need to use for its construction inventory of installation and technological equipment, as well as additional labor and energy costs for the production of concrete work.

The closest accepted by the applicant for the prototype is the solution given in the patent for invention RU No. 2202026, class. Е04В 1/18 "Reinforced concrete frame of the BELGI building." This reinforced concrete frame of the building, including the columns of the outer and inner rows, provided with grooves for installing the ends of the flat rectangular crossbars, while the crossbars of the inner rows are made with shelves for supporting the floor slabs, and the columns are made of rectangular cross-section, the columns of the extreme rows are installed with the larger section side along the wall of the building and the columns of the inner rows are perpendicular to the length of the building, the crossbars of the extreme rows are made with a width equal to or greater than twice the thickness of the column, and are installed in the grooves of the columns extreme rows offset with respect to the columns or not, wherein the crossbars extreme series of crossbars mounted below the thickness of the inner rows of pins.

A disadvantage of the known reinforced concrete frame of the building is the presence of a rigid connection between the crossbar and the column, which leads to an increase in the complexity of construction due to the need to use additional reinforcement of the junction of the crossbar to the column.

The claimed utility model is aimed at creating a reinforced concrete frame of a building with a minimum amount of monolithic work, which has low material consumption and requires less labor for its construction due to the design features of its implementation.

This is achieved by the fact that the reinforced concrete frame of the building, including columns, girders, having along the entire length on each side of the shelf for supporting the floor slabs according to the utility model, the columns are made with consoles for installing the crossbars and are equipped with supporting angles installed at the places where the floor slabs adjoin them, forming a rigid connection with embedded parts of their reinforcement, and the crossbars of the crossbars are made of metal corners rigidly connected to the reinforcement of the crossbars.

The essence of the utility model is illustrated by drawings, where:

figure 1 presents a fragment of the frame of the building, top view;

figure 2 - section 1-1;

figure 3 is a section 2-2;

The reinforced concrete frame of the building consists of columns 1, equipped with consoles 2 for supporting the crossbars 3. The crossbars 3 have projections 4 in the end parts to enable their installation on the console 2 of the columns 1.

Along the entire length of the crossbars 3, shelves 5 are made on each side to accommodate floor slabs 6. The shelves 5 of the crossbars 3 are made of metal corners 7 which are rigidly connected to the reinforcement of the crossbars. Columns 1 are equipped with supporting angles 8, which are installed in the places where the floor slabs 6 adjoin the columns 1. The floor slab 6 is made with trimming in the end part to the width of the supporting corner 8. The supporting angles 8 are rigidly connected with embedded parts (not shown) of the column reinforcement 1. The lower surface of the slab 6 is installed in the same plane with the lower surface of the crossbar 3.

Mounting the frame is as follows. After installing the columns 1, the crossbar 3 with the tabs 4 is installed on the console 2 columns 1. After that, mounted on the column 1 of the crossbar 3 on its shelves 5, made of metal corners 8 install the slab 6. In this case, the slab 6 is at the same level as crossbar 3. At the junction of the junction of the floor slab 6 to the column 1, a corner 8 is welded to the embedded part of the column reinforcement. On the reference corner 8 is brought slab 6.

This embodiment of the reinforced concrete frame of the building can significantly reduce labor and material costs while reducing the time of work.
