Abstract

Usage: in supporting structures of buildings and structures with aggressive media. SUMMARY OF THE INVENTION: A rectangular cross-section beam includes a wooden block frame, a metal reinforcement frame in the form of longitudinal and transverse insert rods, an elastically flexible filler, a plasticizing filler, and a lining of the side faces. The wooden frame is made in the form of axial trusses with parallel and triangular overlays at the nodes. In the supporting zones of the trusses there are rigid inserts. The longitudinal rods of the metal frame are placed along the trusses and connected to them with brackets. Across the farms are glued laminated pads. Vertically across the beams installed glue lining plates. The plasticizing filler is placed between the frames and the linings, and the elastically flexible filler is placed between the linings. Glue liners can be made with jagged edges. Glue-glued and glue-laminated linings and cladding can be made with ligating seams. Facing can be made three-layer. 6 Il. cl

Description

The invention relates to construction and is intended for use as bearing elements in industrial, agricultural and railway buildings and structures exposed during operation to highly corrosive media.

The closest technical solution is a reinforced wood structure with sheet veneer, comprising a composite wooden core of a box-shaped profile, the entire internal cavity of which is filled with an elastically flexible material, and the supporting parts are provided with rigid end caps and reinforced with glue strap as well as longitudinal corner corners. s mi

connected to the transverse rods of the framework of the reinforcing layers.

The disadvantages of the known building element are its increased metal content in combination with heavy workload and the increased complexity of strengthening the supporting parts, insufficient overall and local stiffness of the core, which limits the dimensions of the elements, reduces their long-term stiffness and carrying capacity under the conditions of constant exposure to aggressive media.

The purpose of the invention is to increase the carrying capacity and durability in an aggressive environment.

YY in FIG. one; in fig. 5 - node I in FIG. 2; FIG. 6, node II in FIG. four.

A rectangular cross-section beam includes a wooden block frame in the form of axial trusses 1 with overlays in the nodes, a metal frame in the form of longitudinal 2 and transverse 3 rods, inserts 4 installed in the supporting zones of the trusses, facing the side faces 5, elastically flexible filler 6 plasticizing filler 7. Plate brackets 8 connect the longitudinal reinforcing bars 2 with the truss trusses themselves 1. Gluing pads 9 are installed across the truss trusses 1 and connected to them with brackets 6. Boards 10 anovleny vertically across the beam. The sheet cladding 11 is installed along the upper and lower trusses of the trusses 1. The resilient aggregate 6 is placed between the facings, and the plasticizing aggregate 7 is located in the gaps between the frames and the lining.

Glue lining 8 can be made with jagged edges. Glue-bonding and glued-laminated 10 lining, cladding 11 and cladding 5 can be made with ligating seams.

The lining can be made of three-layer: the inner layer is made of waterproof plywood, and the outer layers are made of thin-sheet textolite on a continuous interlayer of plasticized polymer mastic.
