Description

It is already known to overlap reinforced concrete beams pre-made and from the bottom side covered with clay lining, as well as from hollow stones made of baked clay laid between them. Such overlaps, however, lack a chute, which lies deep between two beams, located directly next to each other, and intended to contain the main iron reinforcement. In addition, in the case of previous ceilings, it was not possible to surround parts of the beams protruding from clay overlays with all the strongholds with concrete. In the proposed overlap, the clay linings of two beams, located directly next to each other, form with their, sloping in relation to each other, bases, deeply lying tolob, and the beams protruding from the clay linings lie freely from all sides. Due to this, the main iron fittings should get the deepest position possible, and the concrete should cover the concrete part of the beams from all sides.

In FIG. 1 depicts the proposed overlap, of hollow in perspective form; FIG. 2 too

(536) /,.

In cross section; FIG. 3 and 4 depict another embodiment also in a perspective view and in cross section.

In the proposed overlap of hollow stones, prefabricated supporting beams consist of a clay overlay a, provided with a longitudinal groove in the shape of a dovetail, and from a concrete rib b poured into the longitudinal groove. in which are embedded iron bars Ci. s held by spacers at a certain distance from each other. Clay linings a, which cover the lower part of reinforced concrete girders, have one of their longitudinal sides that are beveled. The two beams, fr and b, are located directly next to each other, so that their clay linings a and, with the slopes, form a deep-lying chute g, into which the main reinforcing bar /; the latter is located in the same horizontal plane with the iron rods c, on both beams b located directly next to each other. Between two pairs of beams, hollow stones e are laid, after which concrete A is poured, which fills the chute g, the projecting clay pads and some of the beams and, b are covered on all sides.

When using single finished (Fig. 3 and 4) finished clay beams on an overlay a, covering the lower part of reinforced concrete beams b, it is broadened and provided with two parallel longitudinal lobes k, k separated from each other by longitudinal ribs i. Previously: made, equipped with a joint medium with the help of struts of frame bars c, with reinforced concrete - b - b is only in the chute k clay slab a, while the second junction fore k, after laying hollow stones e, for inserting reinforcing : craving / The mass of concrete fills the chute k, and also covers the part of the beam b protruding from the clay face a.

FIG. one ,.

Subject Patent a.

An overlap of hollow stones using prefabricated reinforced concrete beams fitted with clay linings prefabricated from the bottom, between which hollow stones of burned clay are laid, characterized in that the reinforcement bar / concrete h constricts all protruding from the linings of the surface of the beams b, with pairwise (Fig. 1-2) the location of the beams b, b, is placed in the chute between the beams, formed by the slopes of the lining a, when using the same single (fig. 3-4) finished beams in the second; “, Not occupied by the finished beam of the zhol k lining a.
