Description

 The invention relates to building structures of industrial buildings and structures, and is intended primarily for dividing the spans of buildings into separate technological sections, served by common lifting equipment.

There is a known partition of a building and structure, including a casing fixed to a cable-stayed frame, which is made of a transverse cable attached to the supporting nodes of the truss, and vertical cables, the ends of which are connected to the transverse cable, and the casing is fixed to the frame using supporting tables mounted on vertical ropes [1] The disadvantages of the known partitions are:
a) a long installation-dismantling time of the device, since the installation is as follows: a transverse cable is attached to the support nodes of the building farm, then vertical cables attached to it are pulled onto which the casing (panels and asbestos-cement sheets) are hung using support tables;
b) the full perception of the wind load that occurs when opening external openings, and transfer to the building building structures.

Known transforming fence, including a flexible canvas, a frame with rails, cable-block moving system, equipped with upper and lower trusses, installed with the possibility of vertical movement in the rails [2]
This solution is the closest in technical essence to the claimed device.

The disadvantages of the known fencing are:
a) lack of mobility, because can be installed only in a certain place and divide the span of the building into two permanent sections;
b) the transfer of all efforts from possible wind loads that occur when opening apertures, such as gates, to the building structure.

 The technical result of the invention is to eliminate these drawbacks, as well as to solve the problem of increasing the mobility of the structure, i.e. the ability to install fencing quickly and anywhere in the span, and in reducing the effort on building structures from wind loads acting on the partition, for example, when opening external openings in the housing.

 The problem is solved in that the proposed transformable fence, including a flexible canvas, carrying horizontal and vertical cables with a lower horizontal beam, a beam lifting drive, is mounted on a self-propelled power structure that has the ability to move along the entire span of the housing in the sub-truss space; the flexible web is made of separate sections, each of which is pivotally mounted with its upper side to horizontal cables; horizontal cables are connected to vertical ones by means of sliding bushings, which are interconnected by chains.

 The mobility of the fence is ensured by the fact that the canvas is attached to a power self-propelled structure, for example, a bridge of a multi-span crane, which can move along the entire span in the sub-truss space. Due to this, the partition can be installed in any part of the structure.

 Reducing wind loads on building structures is achieved by the fact that when they occur, articulated sections of the canvas deviate from the vertical position, thereby allowing to equalize the pressure on both sides of the fence.

 In FIG. 1 shows the span of the hull in plan; in FIG. 2, section AA in FIG. one; in FIG. 3 section BB in FIG. 2; in FIG. 4 node I in FIG. 3; in FIG. 5 is a section BB of FIG. 2; in FIG. 6 section GG in FIG. 5; in FIG. 7 is a section DD in FIG. 2; in FIG. 8 position of the web section under wind load; in FIG. 9 convertible fence in transport position; in FIG. 10 - node II in FIG. 9.

 An example of the use of the invention is described below when the span of the housing 1 is divided by a transformable fence 2 into two technological sections served by overhead cranes 3 and 4 (Fig. 1); transformable fence 2 is mounted on a self-propelled device 5 and consists of a flexible canvas 6, vertical 7 and horizontal cables 8 (Fig. 8), a horizontal beam 9 and a drive for lifting it 10.

 The flexible web 6 consists of separate sections 11 (Fig. 4 and 8), each of which with its upper end through the hinge 12 (Fig. 7) is fixed to the horizontal cables 8; horizontal cables 8 are connected to vertical cables 7 by means of bushings 13 (Fig. 5), the distance between which, when the web is lowered (guard in the working position) is limited by the length of the chains 14, which are connected between the bushings 13 (Fig. 5). The chain 14 and the horizontal cables 8 are fixed to the bushings 13 with clamps 15 and 16. In the working position of the fence, the beam 9 is fixed to the floor using the grippers 17 (Fig. 4) along the entire length of the beam.

 The device operates as follows.

 The initial position of the transformable device 2 at one of the end walls of the housing, while the horizontal beam 9 and all elements of the flexible web 6 are in the highest position (Fig. 9). If it is necessary to divide the span into 2 required technological sections, the self-propelled power structure 5 moves to the desired position in the span.

 Upon reaching the desired position, the self-propelled power structure 5 is stopped, the drive 10 of the beam 9 is turned on to lower, the beam 9 is lowered to touch the floor, and then attached to it by means of grippers 17 along the entire length.

 When lowering the beam 9 of the sleeve 13, under the influence of the weight of the sections 11, the webs slide along the vertical cables 7. The chains 14, which are rigidly fixed with clamps 15 and 16 to the bushings 13, allow the bushings 13, and hence the horizontal cables 8 with sections 11 of the canvas 6 to be located vertically cable 7 with a certain step. This completes the installation of the fence 2.

 Before installing the fence, the passage of the hull 1 is fully serviced by bridge cranes 3 and 4. Before installing the fence, cranes can be installed in the required combination in any of the sections.

When a wind load occurs sections of the blade 11 deviate from the vertical position, passing air flows
The economic effect of the use of the invention is realized in two directions: in the first case, due to the transformation of the premises into 2 any (in size) sections; in the second case, due to the reduction of wind loads on building structures, which are comparable, and in some cases significantly exceed the loads from the handling equipment.
