Description

one

The invention relates to the construction, in particular, to the structures of wall fences installed in a room with an explosive atmosphere.

Fences of explosive premises of industrial buildings, made of reinforced concrete panels, are known to relieve excess pressure through the glazing of window openings 1 that are destroyed by an explosion.

The disadvantage of this device is the need for glazing in a large area of fencing, which increases the heat loss of the room, complicates the process of installation and rehabilitation works.

A fencing of an explosive room is known, including cells formed between the supporting elements of the coating 2.

The cells are blocked by overpressure-opening sashes of laminated panels, made with profiled panels and frame. 20

This design is of limited use, as it is suitable for buildings with massive walls, the weight of which

exceeds the weight of the coating. In this case, the structure requires the installation of additional connections for rigidity in the places where the opening flaps are installed. The flexibility of opening sashes in wintertime with snow load decreases.

Opening flaps may be deformed if exploded. They are set to their original operating position manually.

Closest to the invention of the technical essence and the achieved result is the design of the fence of an explosive room, including openable wall sections, covered with panel elements installed in the cell frame fence 3.

Panel elements are attached to the frame with a vacuum device.

The disadvantages of such a device are the small area of the wall sections to be opened, the possibility of deforming panels detached from the working position by excessive pressure, and the need for their subsequent manual installation during the restoration of the fence.

The purpose of the invention is to increase the area of openable areas to relieve excess pressure arising from an explosion, and to reduce the complexity of recovery.

This is achieved by the fact that the enclosure of an explosive room contains openable sections of the wall, covered with panel elements installed in the cells of the framework of the fence and connected in each cell by carrying elements into the section attached to the frame on top of the hinges, and to the bottom by elastic links.

FIG. Figure 1 shows a variant of a wall enclosure with an opening section of sheet panels; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the top node connecting the section with the column; in fig. 4 - the same plan view; in fig. 5 - lower unit for connecting the section with the column; in fig. 6 - the same plan view; in fig. 7 is a variant of a wall fence with an opening section of monopanels or sandwich-type panels.

The barrier is made of laminated panels 1. Between the columns 2 of the frame of the barrier of an explosive room are formed cells 3, which are openable wall sections, covered by panel elements 1, combined in section 4. Each section is connected to adjacent columns 2 by means of bows 5 and elastic connections 6 1-1 with elastic ties 6, clamps 7 can be installed to hold the sections in the open position until the external and internal pressures are equalized. The elastic connection can be made in the form of a spring, a flexible compensator, a hydraulic piston, etc. Fixator 7 can be a rigid rod hinged to the column, or a hydraulic piston.

Any lightweight panel can be used as a layered panel, including sandwich panels, monopanels, sheet panels, and others.

When executing the opening sections of laminated panels with the rendered framework, its bolts 8 vertical ribs 9 are connected in a single frame. A hinge 5 is installed on the upper girder 8, and an elastic connection 6 is installed on the lower girder.

The frame of the section with sandwich and monopanel-type panels is horizontal intermediate bolts, 8 half-timbered frames and ribs 9.

In case of panels of the sheet assembly, the inner supporting corrugated sheet 10 with upper and lower bolts 8 serves as a frame.

The load acting on the section is transferred from the laminated panels to the section frame, and then to the columns of the fence through the hinged connection at the top and the flexible connection at the bottom.

The vertical load is transmitted through the hinges, horizontal - through the hinges 5 and flexible links 6. At the same time, the flexible links must maintain geometric unchangeability from the normal operating loads.

In the event of an explosion in the room, under the action of overpressure, section 4 is rotated through a certain angle, and the internal and external pressures equalize through the resulting gap.

The hinges 5 and the elastic connections b ensure the free rotation and return B of the initial position of the sections 4. Structural failure does not occur.

The fence allows organizing the release of overpressure through the opening sections of the wall fence with a large working surface.

The design completely prevents the destruction of any elements of the building, their deformation and the need to restore the panel fencing in the areas to be opened.
