SU77112A1 - Pre-stressed reinforced concrete structure - Google Patents

Description

The proposed construction of reinforced concrete reinforced with pre-stressed elements provides for the manufacture of these elements in the form of bars wrapped with continuous tensioned wire (Figs. 1-5), which are then in the required sequence and in the dimensions of the structure, followed by between the elements is filled with dense concrete.

The shape of the bars has the shape of an I-beam, which allows the tension winding to be separated from the plane of the face of the bars.

Thus, as winding A (Fig. 2) of the elements B is enclosed as a whole. In the zone of future concreting B, then after concreting the structure, monolithic along the structure is formed, which includes highly tensioned reinforcement.

The structure of concrete reinforced with tensioned elements is obtained, which, as shown by experiments, has crack resistance and strength.

Strained members may be located in all directions of the structure. This ensures the construction of cracking in any plane.

An example of a pre-cast monolithic construction is a railroad bridge (Fig. 5).

The span structure consists of a lower bridge 1, made up of tensioned elements, a vertical wall 2 of tensioned elements, and a monolithic relaxed trough 5, which constitutes the upper compressed part of the bridge.

All the individual elements of the bridge are combined into a whole structure by concreting.
