Abstract

The invention relates to construction, is used in folding structures of roofs of buildings, allows to expand the scope of application by forming roofs of various shapes, simplifying the design and reducing material consumption. Folding volume block roof contains a sloping construction panel of roof elements 1, connected by crate 2, attic panel and struts 3. Each rafter element I is supported on the upper face of the beam 4 attic panel and connected to it in the hinge assembly. 5 joints The hinge joint 5 is located at the intersection of the inner face of the truss 1 with the upper face of the beam 4 of the attic panel. One end of the strut 3 is connected through the lug 6 to the beam 4 of the attic panel with the possibility of a connector and positioned in the plane of the building panel when folded. The other end of the strut 3 is connected in the hinge assembly 7 with the truss element 1. Each strut 3 is its side with $ l

The invention relates to the construction and folding structures of buildings can be used.

The purpose of the invention is the expansion of the field of application due to the formation of a roof of various shapes, simplifying the design and reducing material consumption.

Figure 1 shows a collapsible volumetric block krishga in the working position, a general view; FIG. 2 shows a unit for fastening lingering trusses with beams in the attic panel; FIG. 3 shows the location of the beams of the attic panel with lugs, plan view; Figures 4 through 6 show the sequence for converting the collapsible bulk roof unit from the transport position to the working position; in fig. 7-10 - examples of roofs of buildings with different roof profiles.

The collapsible three-dimensional roof block contains a laid-on rafter panel made of truss elements 1, connected with crate 2, an attic panel and struts 3. Each rafter element 1 is supported on the upper edge of the beam 4 of the attic panel and connected to it in the hinge joint 5, which is located on the intersection of the inner face of the truss element 1 with the upper face of the beam 4 of the attic panel;

One end of the strut 3 is connected through the lug 6 to the beam 4 of the attic panel with the possibility of a connector and positioned in the plane of the rafter panel when folded. The other end of the strut 3 is connected in the hinge assembly 7 with the truss element 1. Each strut 3 is aligned with its inner side with the inner lateral surface of the truss

element I. The hinge joint 5 is made by means of a flexible metal strip 8 fixed by panels to the outer face of the truss 1, enveloping its end and fixed by pins 9 on the upper edge of the attic panel beam, starting from the center 10 of the hinge joint 5.

In the transport position, the rafter panel and the struts are horizontal and laid on the upper lining of the attic panel. When the folding surround roof unit is brought to the working position, the free end of the truss elements 1 is raised. In this case, the struts 3, being rotated relative to the hinge assembly 7, are lowered with the free end prior to installation in the design position on the bob 6, followed by attaching metal strips in it.

Claims (2)

The fastening of truss elements 1 by flexible metal strips 8 to beams 4 of the attic panel with the installation of the first bar 9, starting from the center 10 of the hinge joint 5, ensures that the truss elements 1 rotate relative to the center 10 of the hinge joint 5 when moving the truss 1 from horizontal position in working. Spacer forces from truss elements 1 are transmitted. on the beams 4 of the attic panel at the level of the upper edge of these beams with eccentricity relative to the neutral axis of the beams 4, which ensures the unloading moment in the said beams. Invention Formula 1, Folding surround roof unit containing sloping trusses panels of trusses connected by a crate and hinged to the beams of the attic panel, struts, one end of each of which is connected to the beam of the attic panel - and the other hinged to the truss element, in order to expand the field of application the expense of forming crps of various shapes, simplifying the construction and reducing material consumption, the roof block is formed by one inclined panel, each rafter element of which is supported on the upper edge of the attic panel beam and hinged joint the sawing element with the beam of the attic panel is located at the intersection of its inner edge with the upper edge of the beam of the attic panel, with 0 five 0 than each strut with its side surface is aligned with the internal side surface of the truss and is connected through a bob to the beam of the attic panel with the possibility of a connector and positioned in the plane of the truss panel when folded. 2. Roof unit according to claim 1, characterized in that the hinged joint of the rafter element with the beam of the attic panel is made by means of a flexible metal strip fixed with pins to the outer face of the rafter element, which bends around its end and is fixed with pins on the upper edge of the beam from the center of the hinge. 2 tTTT it Fiz.Z ,  X Yu c fig.c FIG. 7 II J4 FIG. eight IT J-L 9 I Phie.
