Description

The invention relates to the field of construction and can be used for arranging coatings of heated, mainly industrial and agricultural buildings. Designs of coatings of corrugated sheets laid on steel girders are known. 1. Corrugated sheets of these structures are loosely laid on a bearing base and do not provide for the perception of heavy loads. Also known is a slab of longitudinal ribs and struts, a profiled sheet, insulation and roll roofing. , thermal insulation, sticks the coil to the roof and makes a protective layer. Fixing the floor does not provide reliable collaboration with his runs. The purpose of the invention is to ensure the joint work of the ribs and the sheet under load. This goal is achieved by the fact that each longitudinal edge is made of a lower and upper profiled half edge, between which a profiled sheet is installed, the sheet profile and half edge profiles facing the sheet are the same, and their contact line is located in the compressed area of the ribs. FIG. 1 schematically shows a plate in plan; in fig. 2 shows a section A -A in FIG. one; in fig. 3 - section B - B in FIG. one; in fig. 4- node 1 in FIG. 3. The plate consists of wooden longitudinal ribs 1 and spacers 2, profiled sheets 3, paroizolation 4, insulation 5 and one layer of rolled roofing material 6. Each wooden edge 1 consists of a lower and an upper semi-edge, and between them is glued with them profiled sheet 3, which cantilever overhangs beyond the outer edges of the longitudinal ribs 1. The lower semi-edges are joined by pins on the glue with spacers 2. The surface profile of the lower and upper semi-edges I facing the profiled sheet 3 is the same as the profile of sheet 3, and the line con act them located in the compressed zone edges. The profiled sheets 3 can be pi nq-flHeny of galvanized steel, aluminum, fiberglass and other materials. Wood fins 1 can be made from solid or glued bars by cutting them

along the line repeating the profile of the profiled sheets.

On top of the profiled sheets 3, a paroizo is glued;

Glue joints of profiled sheets with ribs ensure that the ribs and the sheet under load work together. The profiled sheets provide the overall instability of the ribs and do not experience the compressive forces from the overall bending of the plates. Cantilever overhangs of profiled sheets reduce bending moments in the span of sheets.

The slabs are laid on top of the trussed structures or directly on the walls. The profiled sheets of adjacent plates are overlapped with each other and in order to form a hard disk, or are interconnected, for example, by combined rivets. Strips of rolled roofing material are glued to the joints of the slabs on the mastic. Then additional layers of rolled roofing material are glued.

The primacy of the plates provides a significant reduction in labor intensity compared with the structures of the coatings of profiled sheets stacked on the girders.

The proposed laminated plates can span spans up to 12 m or more. Nesu II and the ability of the plagt may be enough

Large and easily varied by changing the cross sections of the ribs and selecting the required profile sheets. The absence of metal connecting elements makes it possible to implement the metal-free construction of plates, for example, with profiled sheets of fiberglass. The high degree of prefabrication of such plates ensures their economic and practical use in building coatings.
