UA121452U - SPRING COMPLEX LIGHT CONCRETE ELEMENT WITH RIGID ORGANIC ARMATURE - Google Patents

Abstract

The Spring Complex Lightweight Concrete Element contains a rigid organic reinforcement located in the lower area of the Spring Complex Lightweight Concrete Element.

Description

The utility model belongs to the field of construction and can be used in beam and slab structures.

A well-known span reinforced lightweight concrete element, in which metal reinforcement rods of smooth or periodic profile I are used as working reinforcement (Constructions from lightweight concrete on porous aggregates. - K.: Vyshcha shkola, 1988. - P. 185-189). However, in such elements, the rod metal reinforcement complicates the necessary additional processing (trimming, trimming, etc.), which leads to the impossibility of fitting them to the place of use and requires high manufacturing accuracy. In addition, the use of metal reinforcement increases the cost of such a reinforced element. Light concrete itself is a rather fragile material and therefore requires careful handling, especially with accidental shock loads accompanying the installation process.

The basis of the useful model is the task of creating a reinforced complex lightweight concrete element, in which, thanks to the maximally simplified processing of the finished element (without the use of special tools and devices), an increase in the strength of the lightweight concrete element and the possibility of using it as a span, with a simultaneous reduction in the cost of the element, will be achieved. The protective shell will ensure the integrity of the element during transportation and installation.

The task is solved by the fact that the span complex lightweight concrete element containing rod reinforcement, according to the useful model, contains rigid organic reinforcement placed in the lower zone of the span complex lightweight concrete element. The lightweight concrete body of such an element, made of gas or foam concrete, is protected by a shell of constructive lightweight concrete, for example, expanded clay concrete or slag concrete.

Rigid organic reinforcement, for example, rods or other assortment of organic origin, allows you to increase the bearing capacity of a spanned complex lightweight concrete element and perform the necessary additional processing of this element in any place without the use of special tools, and the protective shell - to prevent the destruction of the fragile core.

The proposed useful model is explained by drawings. In fig. 1 shows a span complex lightweight concrete element, where 1 is a form for expanded clay concrete or slag concrete

From the mixture, 2 - a protective shell made of expanded clay concrete or slag concrete, C - a lightweight concrete body of a span element made of gas or foam concrete, 4 - rigid organic reinforcement (for example, rods of organic origin). In fig. 2 section 1-1 in fig. 1, where 1 is a form for expanded clay concrete or slag concrete mixture, 2 is a protective shell made of expanded clay concrete or slag concrete, 3 is a lightweight concrete body of a span element made of gas or foam concrete, 4 is rigid organic reinforcement (for example, rods of organic origin).

A span complex lightweight concrete element with rigid organic reinforcement is made in this way.

The lower layer of the protective shell 2 made of expanded clay or slag concrete is placed in the form 1, into which we sink the rods of organic origin 4, which are the working reinforcement of the spanned complex lightweight concrete element. Rods 4 must be fixed in form 1 in the lower, most stretched zone of the element, ensuring the installation of a protective layer. Next, we install a foam or aerated concrete body 3 on the lower layer of the protective shell 2 and arrange the side and upper layers of the protective shell 2 from expanded clay or slag concrete.

Such a solution of a spanned complex lightweight concrete element allows to improve its performance by increasing strength, crack resistance and stiffness, reduces cost and allows additional processing with ordinary household tools, without the use of special ones, and to ensure protection of the lightweight concrete body from negative effects on it.
