Problems solved by technology

However, if the wrapping layer is too thin, the wrapping layer will be damaged and the insulation performance will be reduced during the binding assembly or concrete pouring of reinforcements for concrete such as steel bars wrapped with insulating materials.

Embodiment approach 2

[0067] Next, see Figure 8 , to describe the method of using the electrically insulating and wrapped ribbed steel bar 33 manufactured by the above-mentioned manufacturing method for a track slab. in addition, Figure 8 , is a view showing a rail slab embedding the insulating sheathed steel material of the present invention using a ribbed steel bar, wherein (a) is a plan view, and (b) is a front view.

[0068] The concrete track slab 6 of illustrated embodiment, as Figure 8 As shown, it is a reinforced concrete slab with a length of 5m, a width of 2m, and a thickness of 0.19m. Two rails 7 , 8 are arranged symmetrically about the central axis in the concrete rail slab 6 . In addition, 17 in the figure is an embedded bolt (internal threaded part).

[0069] In order to withstand the load of the vehicle, the illustration is omitted, but in general, unwrapped ribbed steel bars are pre-embedded in the track slab as a reinforcing material for concrete. However, when a high-frequ...

Abstract

The invention provides a insulation package reinforcement material which is electrically insulation packed by electrical insulation material having high electricity insulation property. A electrical insulation material packing layer is formed by packing conductive reinforcement materials for concrete buried in the concrete such as round steel, steel bar with rib with electrical insulation material, and producing surface of the electrical insulation material packing layer into a coarse surface, and is used as the insulation package reinforcement material buried in the concrete produced by the process.

Description

technical field [0001] The present invention relates to a reinforcing material for concrete in which an electric insulating material is applied to the surface of a reinforcing material for concrete such as a round bar and a ribbed steel bar used in a reinforced concrete structure, and a method for manufacturing the same. Background technique [0002] In a reinforced concrete structure, as reinforcing materials for concrete such as round steel bars and ribbed steel bars buried in concrete for reinforcement, steel bars that have not been subjected to electrical insulation treatment are used as they are. [0003] However, if it is placed in the concrete of the reinforced concrete structure for railways such as concrete track slabs or concrete sleepers for ballastless tracks, concrete roadbeds, concrete panels, and concrete fenders, the electric insulation When a plurality of metal reinforcements (non-insulated metal reinforcements) such as processed round steel and ribbed steel...
