Abstract

The present invention relates to an integral concrete lining body and a manufacturing method thereof. A pipe is formed on a bolt hole of a floor plate so that a bolt or a nut is introduced into the pipe to be prevented from being exposed to the outside when the concrete lining body and a mold beam are coupled to each other. Therefore, concavo-convex portions can be minimized when a vehicle passes so that passing inconvenience can be removed. More specifically, a separate hole is not required to be formed on the concrete lining body for installing the bolt or the nut so that construction can be further simplified and operability can be further improved.

Description

Integral concrete reinforcing body and its manufacturing method {Concreat deck plate and manufacturing method thereof}

The present invention relates to an integral concrete reinforcing body and a method for manufacturing the same, and more specifically, it does not require a separate drilling operation, thereby simplifying the construction process and, accordingly, the integral concrete reinforcing body and its It relates to a manufacturing method.

In general, the perforated plate is used to cover the road surface so as not to interfere with the passage of pedestrians or vehicles when digging roads or installing temporary bridges for the construction of underground facilities such as open-type excavation or subway construction, or large buildings with a steel structure Or used as a flooring material for parking facilities made of steel structures.

Conventional perforated plates use only steel and the “c” -shaped steel and “L” -shaped steel frame are in close contact with each other, then turned over and welded to the inside, and “H” -shaped steel is used to closely contact each other. It is manufactured by welding the lower part.

All of the above-mentioned double-plates are expensive due to the large amount of steel, and due to the nature of the steel, the road surface is slippery, so a separate anti-skid facility is required. In order to compensate for this, there is a reinforcing plate made of concrete and reinforcing bar or concrete and steel, but this is too heavy and increases the production cost, which is an uneconomical problem.

In addition, when the conventional concrete perforated plate is simply mounted on the mold beam without fixing, noise caused by collision between the perforated plate and the mold beam when driving the vehicle is naturally caused, and thus a complaint problem constantly occurs.

In addition, the conventional concrete reinforcing plate punches a separate hole in the field for mutual coupling with the mold beam, and the construction is complicated and the workability is complicated because the reinforcing plate and the mold beam are interconnected by fastening bolts and nuts with the perforated parts. There was a fundamental problem of falling significantly, and it was easy to crack in the concrete during the drilling process, and there was a problem that it was easily damaged during repeated driving of the vehicle in the cracked state.
