The invention relates to the construction, in particular to industrial roofs of buildings with a roll-free roof and an external drain.

The purpose of the invention is to reduce the labor and material intensity in the manufacture and installation of the roof, increasing its operational reliability. FIG. 1 shows an industrial roof with a roll-up roof, a plan; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 — node 1 in FIG. 2

The roof contains reinforced concrete L-shaped frames of the lower 1 and upper 2 Rus, the rafters of which are made in the form of a tray. In the lower part of the frame, there are transverse support ribs 3, cantilevered sections 4 and longitudinal ribs 5. Reinforced concrete roofing panels 6 are supported on the ribs 5 of the frames, which have drip 7 on the lower face, and on the upper front surface of the rib 8 forming with the lower edge of the panel isosceles triangle. The frames of the lower rusa 1 are supported on the bracing beams 9 and 1 of the outer and inner walls, and the frames of the upper rusa 2 by means of transverse support ribs 3 - on the ridge assembly of the frames of the lower rusa 1, and the trays of the upper rusa frames of the trays of the lower rus are wide ribs 5 and the console section 4 overlap the transverse joints. The transverse joints of the roof elements are also overlapped by plates 6 of the upper rus and ridge element 11. The metal fasteners I2 connect the ridge nodes of the frames of the lower russ 1.

The roof is mounted as follows.

Initially, the lower beam frames are installed on the straightening beams 9 and jО. The ridge knots of the frame are connected with metal bands 12. After that, the frames of the upper wheel 2 are installed. The frames are wide enough to ensure their stability without additional temporary fixings. The races of the frames' frames are located one from another at a distance commensurate with the width of the roofing panels 6. At

the fins 5 of the frames are laid down the roofing panels 6 of the lower and then upper Russ. The ridge of the roof panels 6 is closed with a ridge 5 element 11i

. All major roof elements are manufactured in cassette. or bench metal forms. In order to simplify the technology of preparing products and transporting them to a construction object, it is possible to form D-shaped frames from two linear parts with the subsequent assembly of the frame on the conductor using

15 embedded parts, linings and welding in the ridge unit. The puffs connecting the ridge nodes of the lower russ frames allow the location of these nodes to be fixed at

20 loading, which excludes the rise of considerable horizontal forces in their supporting parts and ensures the simplicity of the constructive solution of the assembly of the supports of the lower

25 Russo on the outer walls.

To increase the rigidity of roofing panels and their bearing capacity for various types of loads, fins are provided on the front surface of the panels. These ribs make it possible to arrange reinforcement frames in them, ending in the lower corners of the panels with two mounting loops; In the manufacture of panels in horizontal forms with ribs downward, the removal of products and their translation into a vertical position is carried out with the help of these assembly hinges, which are also used for installation on a building site. The ribs allow conventional slinging arrangements, such as a two-legged sling, to be used for demolding and installation. In this case, the force from the sling when turning the panel from the horizontal (during dismantling) to the inclined (during installation) position is directed at an angle to the front face of the panel and is perceived by the ribs.

 The location of the ribs on the front surface of the roofing panels also contributes to the direction of water flow into the drainage trays formed by the rafters of the L - shaped empty frame ary system.
