SU32127A1 - Interfloor overlap - Google Patents

Description

The invention aims, at the transition of industrial construction to the beginning of production, to produce in advance, in business courtyards, beams and slabs that constitute an interfloor overlap with their subsequent installation at the production sites in finished form.

In FIG. 1 shows the beams and the slab of the proposed overlap in vertical section; FIG. 2 is a section along the line AB in FIG. one; FIG. 3-section on Cd in FIG. 1 and FIG. 4-general view overlap.

The proposed interfloor overlap consists of concrete or reinforced concrete beams, the spans between which are covered with slabs of the same material.

The slabs (Figs. 1 and 2) are an elliptical thin-walled roof 5, embedded between two thin-walled concrete cheeks 2 with filling of the sinuses of the vault and the underwater space with some kind of conductive material, low heat and light material, such as: foam concrete, pumice concrete, fibrolite, and fibrous lithium fiber, and lightweight material, such as: foam concrete, pumice concrete, fibrolite, and fibrous lithium fiber, and lightweight material, such as: foam concrete, pumice concrete, fibrolite, and fibromite. Plate 3 works as an elliatic thin-walled 351

roof with cheeks in the form of lateral cheeks 2. The resulting spread in arch 5 is transferred to cheeks 2 by the ability of the concrete to work for chipping. Beams 4, similar to the slab design, consist of an elliptical thin-walled vault (Figs. 1 and 3) i which are laterally embedded in the concrete jaw thin-walled walls 7. The latter have longitudinal shoulders 8, on which the plates 3, the helixes and the subsurface space of the beams are filled are the same material as the slabs.

The construction of the ceiling is carried out from the condition of preserving the thickness of the intermediate floor slab equal to that of the wooden beams, for which the height of the slabs is taken into account with the given condition.

After the beams and slabs are put in place, there is no need for making special binders for plastering the bottom surfaces of the plates and beams, and the use of scaffolding for laying floors, as well as ebols, is no longer necessary.

The subject matter of the invention.

The floor of concrete or reinforced concrete beams, the spans between which are covered with slabs of the same material, characterized in that both the beams themselves and the slabs that are supported on them consist, each, of two parallel concrete cheeks 2, 7 of a rectangular outline and from the arch-arched slab 7, 5 between them, forming one whole with them, and the whole space between the cheeks D 7, as well as the top and bottom of the arches /, 5 is filled with thermal insulation material (foam concrete, aerated concrete, fiberboard, etc. ), so that each beam or slab, and It has the form of a rectangular parallelepiped, in which both vertical longitudinal faces are concrete, and both horizontal longitudinal faces are from a filling insulating material.
