SU41147A1 - Combined tent reinforced concrete interfloor overlapping - Google Patents

Description

The invention relates to precast reinforced concrete floor decks of a hip type, consisting of slabs resting on columns and overlapping the floor between columns.

The novelty of the invention lies in the fact that the plates resting directly on the columns (pillars) have a trapezoidal shape and are laid in place with a corresponding slope, forming a tent, the edges of which are the slanting sides of the trapezium, with which each of these plates adjoins the adjacent plate.

Floor slabs can be made in the form of frames with easier filling, for example, wood or fiberboard.

In FIG. 1 depicts a single overlap cell in section along the AB in FIG. 2 (two embodiments of solid reinforced concrete slabs are indicated); FIG. 2 - plan of one cell overlap; FIG. 3 is a diagram of a part of the overlap in the plan; FIG. 4 - one overlap cell in section along the VT in FIG. five; FIG. 5 is a plan of a ceiling cell made of reinforced concrete frames replacing

plates; FIG. 6. - cut along the DE in FIG. five; FIG. 7 - a section along the column.

The slabs 1, having a trapezoid shape in plan, rest on the columns (pillars) 2 and are adjacent to the adjacent plates of the cell by oblique sides 3, occupying an inclined position. On these trapezoidal plates rests the central horizontal plate 4. The Nlits have ribs 5 on the top (the right part of fig. 1) or ribs 6 on the bottom (left part of fig. 1).

Plates 1 can be made in the form of closed rod-shaped reinforced concrete frames (Fig. 4 and 5), - which, after installation on columns, form the tent frame. The space between the frame pins can be filled with fiberglass or wood. The horizontal overlap can be formed by a wooden shield. It is advisable to make this shield out of two matching bars resting on the corners of the trapezoidal frames, thus excluding the bending of the frame bars from the pressure of the central shield. The flooring is laid on these crossing bars.

The connection of individual plates into a monolithic structure is carried out by the edges of their contact by releasing the reinforcement from the fins and then pouring the joints between the fins with concrete (Fig. 6) .-.

The columns 2, on which the transicoidal plates are supported, have for this a small capital 7 (Fig. 1, 4 and 7), on which eight elements of four cells are laid, forming a slot for the installation of the column 8 of the upper floor.

The subject matter of the invention.

Claims (2)

1. Precast reinforced concrete floor slab, supported by on racks, consisting of prefabricated reinforced concrete slabs, jointly covering the floor between racks, characterized in that the plates 1 of each floor, resting on the ends directly on the racks 2, have a trapezium shape and, being laid in place with a corresponding inclination, form a hater , the edges of which are the oblique sides of 3 of these trapezes, with which each of the marked plates 1 adjoins the adjacent plate. 2. The form of overlapping according to claim 1, characterized in that each of the plates forming it consists of a reinforced concrete frame and an easier filling, for example, wood or fiberboard. ; figure 4 J
