Armature for horizontal reinforcement of stone masonry, process for manufacturing the armature for horizontal reinforcement of stone masonry and process for horizontal reinforcement of stone masonry

摘要

The invention relates to construction, in particular to armatures for horizontal reinforcement of stone masonry, processes for manufacturing the armature for horizontal reinforcement of stone masonry and processes for horizontal reinforcement of stone masonry from such materials, such as brick, blocks of heavy, light or porous concrete, blocks of natural stone, and can be used in the erection of buildings of various destination, including in seismic areas.The armature for horizontal reinforcement of stone masonry is made of steel hot-rolled strip in the shape of a grid with rectangular windows, comprising two straight longitudinal continuous bars (2) of the same width, placed at a distance of 25…50 mm from each other, interconnected by batardeaus (1), the joints of which with the longitudinal bars (2) are made rounded.The process for manufacturing the armature for horizontal reinforcement of stone masonry includes punching in a steel hot-rolled strip of a thickness of 0.8…2.0 mm of Z-shaped holes, arranged with respect to each other so that on the edges of the strip are formed straight longitudinal continuous bars, and between the holes are formed batardeaus parallel to the longitudinal bars; stretching of the strip in transverse direction up to the rotation of batardeaus by 90° to form a grid with rectangular windows; cold hardening of the resulting grid with simultaneous finishing to form on its seams corrugations of arbitrary shape; cutting of armature into measuring products of a given length.The process of horizontal reinforcement of stone masonry comprises placement of said armature at an interval of at most 400 mm on the height of masonry, at the same time in each tier of masonry the grids are placed separately in pairs, and the distance from the outer longitudinal bar of the grid up to the corresponding edge of the wall is 5…15 mm.
