Description

(54; BUTTON CONNECTION CASTLES BOOT-FREE CONCRETE COVERING WITH COLUMN

This invention relates to construction. It can also be used in mates of supporting structures of flush-mounted ceilings.

It is known to joint a slab of slabs with a column with a column in which the capital has a protrusion of the concrete body in the central part, and the column is extended with broadening for bearing capitals, with the gaps between the surfaces of the plate orifice and the broadening of the column being monolithic p1.

The disadvantage of this compound is the complexity of the shape of the capitals and columns with a low joint stiffness.

The closest to the invention in technical essence and the achieved effect is a butt joint of a capitol of a beamless reinforced concrete overlap with a column, including the central part of the intersection plate with the expanding downward hole and reinforcing

and the columns enclosed in the shoulders on which the slab rests, and the gaps between the surfaces of the plate opening and the shoulders of the column are monolithic L j.

The disadvantage of this connection is the low reliability of the butt joint due to the presence of gaps between the support planes of the capitals and the columns.

The purpose of the invention is to increase the reliability of coupling the column to the capital.

Claims (1)

The goal is achieved by the fact that in the butt joint the capitals of the beamless reinforced concrete slab with the column, including the central part of the slab with the downwardly widening hole and the reinforcement outlets of the column and slab, a reinforcement cage protruding from the plane of the truncated pyramid shape or a truncated cone and attached to the armatures of the column and capitals, the column in the joint zone is {profiled with alternating grooves and ridges, and the cavity is monolithic . On the fil, 1 is shown the butt joint of the capitals of the beamless reinforced concrete slab with the column in terms of FIG. 2 — section A-A-Ia of FIG. 1. The connection of the capitol of the flat beaded reinforced concrete ceiling with the column includes column 1, capital 2 with a through hole in the form of a truncated pyramid or a truncated cone, console 3, fixtures in the column 4, fixtures capitals 5, reinforcement cages 6, reinforcement outlets capitals 7 The installation of a butt joint follows in a consistent manner,. A small capital 2 is installed on Column 1, while the side faces of the through hole are supported on the console 3 attached to the mortgage parts 4, after alignment the console 3 capitals are attached to the mortgage parts 5, then reinforcement cages 6 are installed and attached to the mortgage parts 4 and to the outlets 7, after which between the ribs of the lower base of the through hole and opposite sides of the column, formwork and the resulting cavity 7 with reinforcement cages included in it are filled with concrete. union joint improves reliability while simplifying capitals formworks and pillars. Claims of the invention: Butt joint capitals without beamed reinforced concrete floors. with a column, including the central part of the pin with a downward opening and reinforcing implants of the column and pin, characterized in that, in order to increase the reliability of conjugation of the column with the capital, the reinforcement frame protruding from the plane of the capital into the opening the shape of a truncated pyramid or a truncated cone and attached to the armature fittings of the column and capitals, the column in the joint zone is filled with profiled and alternating grooves and ridges, and the joint cavity is monolithic.
