RU205385U1 - Composite column - Google Patents

Abstract

For the device of load-bearing columns at high loads, a composite structure of galvanized profiled sheets H153 - 0.8, length up to 15 m, is proposed. the vertical part of the column through the transition elements. In the presence of ceilings and support beams, overhead welded consoles are installed for them with a connection to each other with galvanized studs with nuts and locknuts. The proposed design differs from analogues in lower weight.

Description

The arrangement of column structures is carried out by joining sheets of galvanized profiled decking of the required length (up to 15 m) through fiberglass gaskets impregnated with epoxy resin and closed through connecting elements by base plates made of galvanized sheet steel with a thickness of up to 6 mm.

State of the art

For the construction of frame multi-storey buildings with a large load on the supporting columns, columns made of rolled steel (I-beams, channels) are used, connected by welding, from rolled pipes, combined from rolled steel and pipes filled with concrete, from reinforced concrete with reinforcement of more than 50 kg per 1 m ³ carried out both in the factory and on the construction site.

Considering as an analogue existing patents for the reinforcement of reinforced concrete columns, which is necessary to increase their bearing capacity, the presence of framing frames made of metal corners was established (SU 1279768 - authors Rabinovich E.A. and Blogs R.L., RU 9243841 - authors Shchaponov R.P., Teryanik V.V.), which confirms the need for the construction of columns, ensuring the perception of large loads, which is provided either by a significant increase in the reinforcement of 8 reinforced concrete columns - up to 200 kg / m ³ , or by a significant weight of rolled beams - 138 kg / running meter, or by changing the design of single-branch columns to two-branch ones.

The difference between the proposed utility model of the column structure from analogs is:

lower dead weight of the metal in the column structure with the same bearing capacity.

The technical result of the proposed utility model

Composite load-bearing column for high loads from floors and roofs, made without the use of special equipment, with a lower metal weight.

The task of the technical result when using

Manufacturing of load-bearing columns in the construction of multi-storey buildings with large payloads on floors and roofs.

Characteristics of the utility model

The heavy load composite column structure consists of:

galvanized profiled sheets Н 153-0.8 up to 15 m long;

connecting gaskets made of 20 × 2 mm fiberglass tapes impregnated with epoxy resin;

transition elements for connecting to the upper and lower base plates;

supporting top and bottom plates made of galvanized sheet, 6 mm thick;

overhead steel consoles in the presence of supporting floor beams.

The design differs from analogs in lower weight.

Implementation of the utility model

The use of the proposed utility model can be carried out in the manufacture of load-bearing columns in the construction of multi-storey buildings with large payloads on floors and roofs.
