Abstract

Use: in buildings and structures to protect against debris from the destruction of building structures. The essence of the invention: the coating is made in the form of semi-amps, on the outer side of which a string is mounted, with one end fixed on a support and the other on the upper end of the semi-arch. The upper ends of the semi-rollers are connected by a flexible insert. In the longitudinal direction between semi-aisles, flexible girders are located, on which a soft roof is laid on a metal grid. 2 Il.

Description

The invention relates to the construction and can be used in buildings and structures to protect people and property from the collapse of the cover in case of accidents, earthquakes and other extreme situations.

The purpose of the invention is to increase the safety of the coating under dynamic effects.

Figure 1 shows a fragment of a vaulted cover; Fig. 2 shows the assembly of the carrier to the support.

The vaulted cover is mounted on support 1. The coating is made of composite bearing elements in the form of semi-arches 2, which are connected to support 1 by hinge 4. On the outer side of semi-armature 2 there is a string 3, which is fixed by one end on support 1 at point 5 and the other end the upper end of the semi-ancient 2. The hinge 4 is located on the outer side of the support 1 and is displaced relative to the attachment point 5 of the string 3 and the axis

supports 1. The upper ends of the semi-laminates 2 are interconnected by a flexible insert 6. In the longitudinal direction between semi-semi-angles 2 there are flexible runs 7, on which a soft roof 8 is laid on a metal grid.

In extreme situations, when exposed to dynamic loads, the vaulted coating works as follows.

The dynamic load, acting on the vaulted roof, through the roof 8, the flexible girders 7 and the insert 6 is transmitted to the supporting elements from the semi-arches 2. The semi-arches 2 tend to rotate in the hinge support 4. As a result, the string 3 fixed at one end on the support 1 at the point 5, and the other, towards the upper end of the semi-doubles 2, begins to deform, elongating. Semi-pattern 2 is displaced and rotated in hinge 4, and string 3 is tensioned and suppresses the displacement of semi-assembly 2, thereby increasing the safety of the arched floor when exposed to dynamic loads.

In this process, the kinetic energy acquired by the semi-mark 2, under the action of dynamic loads, is expended on the plastic deformation of the string 3, which keeps the coating from falling off.

When the string 3 is broken, when its elongation under the action of dynamic loads may exceed the maximum permissible deformations, the supporting elements in the form of semi-arrays 2 are also retained, without breaking, on the support 1 by the hinge 4 and flexible inserts b and thereby increase the safety of the vaulted floor covering during dynamic influences x.

Placing the soft roof 8 on top of the flexible insert 6 and the purlins 7 provides the necessary temperature and humidity conditions inside the building under normal operating conditions.
