Abstract

Passing structure is related to building industry. This structure has shrouds and a passing beam, ends of which rest on columns or on support walls. Support planes are arranged at an angle. To increase rigidity and supporting ability the passing structure additionally has seats, dyads and tightening. Dyads, nodes of which are additionally connected by the tightening element over the curve of building raise, are rigidly attached to the lower fillet of the passing beam. Ends of the tightening element are anchored at support seats that are rigidly fixed to the ends of the lower fillet of the passing beam. The dyad nodes are connected by shrouds top the columns or support walls over the level of the lower fillet of the passing beam.

Description

Description of the invention

The invention relates to construction and can be used in the construction of new and reconstruction of floors of 2 existing buildings.

A hinged structure is known, which contains cables and a hinged beam, and the ends of the hinged beam are freely supported on columns or load-bearing walls, and the bearing planes are made at an angle (author's certificate of the USSR

Mo1692424727-11, bulletin Mo21 1974.)

In this design, the cables are arranged horizontally with their ends attached to columns or load-bearing walls and 70 work independently of the girder. In addition, the above-mentioned arch construction is characterized by increased deformability and is unsuitable for covering large spans.

The invention is based on the task of creating a thrust structure in which, by changing the shape of the cables, the method of supporting the thrust beam and introducing a reinforcing conditional truss into the thrust structure, the complex operation of the elements of the thrust structure would be ensured, thereby increasing its rigidity and load-bearing capacity.

The task is achieved by the fact that the thrust structure, which contains cables and a thrust beam, and the ends of the thrust beam are supported on columns or load-bearing walls, and the bearing planes are made at an angle, according to the invention, additionally contains support chairs, dyads and tension, and dyads, nodes which are connected by a tension along the curve of the construction rise, rigidly attached to the lower belt of the thrust beam, the horse tensioners are anchored on the supporting chairs, rigidly attached to the ends of the lower belt of the thrust beam, and the nodes of the dyads are connected by cables to the columns or bearing walls above the level of the lower belt of the thrust beam , The use of dyads and tightening allows you to create a so-called conditional truss that reinforces the purlin beam. Attaching the cables above the lower belt of the span beam creates the possibility of the bearing beam resting on the nodes of the conditional truss, each of which is supported by cables in its turn, ensures the complex operation of the load-bearing elements (cables, the traverse beam and the conditional supporting truss), allows to achieve an even distribution of forces, additionally " to relieve the load on the beam, thereby increasing the stiffness and load-bearing capacity.

Fig. 1 shows a hinged construction with support on columns;

In Fig. 2 - a hinged structure with bearing on load-bearing walls, where 1 - hinged beam, 2-supporting chairs,

C-support rollers, 4- columns, 5- bearing walls, 6- dyads, 7- knots of dyads, 8- tightening, 9- cables. She

Girder beam 1, the supporting chairs 2 of which are made obliquely, is supported on columns 4 (or bearing walls 5) through support rollers. At the same time, knots 7 are attached to the lower girdle of the girder beam 1 by diads, which are connected to each other by a tie 8 attached to the support chairs 2. The knots of the conditional truss 7 are simultaneously attached by cables 9 to the columns 4 (or load-bearing walls 5). Gee)

The action of the thrust structure is as follows. Under the action of the external distributed load on the 3o deflection beam 17 in the support rollers C, inclined compressive reactions occur. At the same time, as a result of the deformation Z of the deflection beam 1, tension forces arise in the cables U. The horizontal components of these forces and reactions of support rollers З form support moments. The action of the lower belt of the conditional truss is equivalent to increasing the height of the span beam 71 and, together with the cables 9, increases the bearing capacity and reduces the deformability of the span structure 1. As a result, the span structure 1 can be used to cover significant spans. From the village of
