Description

(54) FOLDING UNIT

I

The invention relates to the construction of inventory structures, mainly canopies.

According to the main author. St. No. 732469 is known for a folding block of fencing, including cross trusses with upper and lower trusses, braces and common stands at the intersections of trusses, some of which are made solid with rigidly interconnected hooks and common stands. SA and bracing which are hinged to the common posts and panels of fences. This device is made with panels protruding to the outside, attached to the top along folding farms themselves, and has U-shaped slats secured to the top along solid forms, and movable joints hinged to the ends of braces of folding trusses, the axes of which are horizontal, and the upper and lower sa are offset from each other 1.

However, such a structure requires additional labor on the construction site for the installation and fastening of columns in the construction of sheds and other structures.

The purpose of the invention is to reduce labor costs on the construction site during the erection of sheds.

The goal is achieved by the fact that the folding block of fencing is equipped with columns hinged on the lower ends of whole farms, odd from the edges of the structure, and self-centering traps installed on the upper ends of whole farms with the ability to interact with the upper ends of the columns, rollers.

FIG. Figure 1 shows the structure of the folding guard unit in the transport position; in fig. 2 - the same, in the process of unfolding (or folding); in fig. 3 - the same in the working position.

Folding fencing block includes

15 a cross grid in which solid trusses 1 and 2 of one direction, respectively, odd from the edges of the Structure, are pivotally connected to folding trusses 3 in the other direction. Fences 4 are attached to the upper 20 folding farms 3, and 1 and 2 - lugs 5-7. To the ends of the bottom of full-bodied farms 1

on hinges 8, columns 9 are attached, interacting with their upper ends due to abutment with self-centering traps 10 made, for example, from V-shaped curved strips attached to the ends of the upper parts of these same trusses 1. The lower ends of the columns 9 are equipped with rollers 11. The skeleton of the structure can be made of metal profiles, the spikes from a bent metal strip, the panel of fences from a metal sheet. In the transport position, the structure has the form of a compact block package (cf. Fig. 1). When this column 9 are parallel to the whole farms 1.

At the construction site, the block package is released from fasteners, lifted by a crane, and when the columns 9 under their own weight occupy an upright position all the way to their upper ends in self-centering traps 10, the entire structure is installed by the rollers 11 on the inventory rail foundations. The structure is then deployed, for example, by a winch horizontally to its working position. No extensions or fasteners are required. k

Thus, the proposed device is a collapsible canopy of full factory readiness, which allows reducing labor costs on the construction site during the erection of canopies by 5-6 times. The maximum dimensions of the structure in working position, providing the possibility of its transportation in the transport (folded) position by rail - 24.0 X 18.0 m.
