Description

The invention relates to the construction, in particular to the reinforced concrete elements of the walls of prefabricated silostores, tanks, etc. Curved reinforced concrete elements are known for prefabricated silo-type storages containing reinforced concrete intermediate stops for fixing extended working reinforcement inside reinforced concrete element 1. However, the lugs of this design result in the appearance of cracks at the interface with the surface of reinforced concrete lugs, which reduces the durability of the extended working reinforcement due to its corrosion. The closest technical solution to the invention is a curvilinear reinforced concrete element for collecting silo-type storage facilities, including a concrete body with a cylindrical inner surface, extended working rods having bends, rods arranged parallel to the cylindrical surface and fixed on intermediate stops installed at the bend of working rods, in which the practical stops are made in the form of reinforced concrete parallelepipeds connected by rods, and the stops are The distance is less than their length, and the parallelepipeds of adjacent stops are placed in a chessboard order G2. However, the stops of this design also lead to the appearance of cracks at the border with the surface of the reinforced concrete parts of the stops, which reduces the durability of the reinforced concrete element. The purpose of the invention is to increase the resistance of the reinforced concrete element and durability. The goal is achieved in a curved reinforced concrete element for precast storage silos, including a concrete body with a cylindrical inner surface. Extensive working rods with bends, rods arranged parallel to the forming cylindrical surface and fixed to the intermediate stops installed at the bend points. working rods, each intermediate stop is made in the form of a plate, having bends relative to an axis parallel to the bisector of the angle at the points of bending of the rods, perty on the rods located parallel to the forming cylindrical surface, and the stop is rigidly attached to these rods m. In addition, the intermediate stops are fastened in pairs by a rod in the area between the fastened stops. FIG. 1 shows a reinforced concrete element, a longitudinal section; on . FIG. 2 — node G in FIG. one; on fig.Z-section A-A. in fig. 2; in fig. 4, node I. Reinforced concrete curvilinear element 1 with an inner cylindrical surface 2 contains stretched working reinforcement 3, which is supported in places of bend 4 on rods 5, which are parallel to the forming cylindrical surface 2. Intermediate stops b are made in the form of a plate having bends relative to an axis parallel to The bisector of the angle at the points of inflection 4 working reinforcement 3. The rods 5 are rigidly attached to the edge of the stop 6 by means of electric welding. The stops b are fastened in pairs by a rod 7 located parallel to the extended working reinforcement 3 in the area between the fastened stops b. In the inflection zone 4, the force arising from the extended reinforcement 3 is transmitted at the point of contact to the rods 5, then to the stops 6 and to the concrete body 8. The invention improves the crack resistance and durability of the concrete element, as well as reduces the labor intensity of the element production.
