ethod for strengthening cracked metal thin-wall element of span structures of bridges // 2642758
FIELD: construction.SUBSTANCE: strengthening method includes drilling a hole at the crack mouth, applying a solder, installing strengthening elements in the form of straps installed on both sides of the metal element, and local heating to the melting point of the solder. The hole in the crack mouth is drilled with a diameter of at least two sheet thicknesses, a paste-like solder is applied to the strap surface, and a mushroom-shaped strap is installed by inserting its stem into the hole. The clearance between the strap stem and the beam wall in the hole is 0.2-0.25 mm, the pressing force is not less than 0.2 MPa. The strap due to the solder adhesion with the base metal is involved in the joint work with the main element.

Horizontal road marking (versions) // 2642746
FIELD: construction.SUBSTANCE: light sources, such as car headlights, emit radiation, including that in the form of visible light.
