Pre-embedded Piece, Method for Producing the Same, and Reinforcing Steel Structures Including the Same

Abstract

A pre-embedded piece includes a reinforcing steel bar and a screw rod. The reinforcing steel bar includes a body and an embossed portion formed on an outer periphery of the body. An end of the screw rod is connected to an end of the reinforcing steel bar. A method for producing a pre-embedded piece includes preparing a reinforcing steel bar and a screw rod. The reinforcing steel bar includes a body and an embossed portion formed on an outer periphery of the body. The reinforcing steel bar and the screw rod are placed end to end and fused together. A reinforcing steel structure of an embodiment includes a plurality of main bars, a plurality of hooped columns, and a plurality of pre-embedded pieces. A reinforcing steel structure of another embodiment includes a plurality of hooped columns and a plurality of pre-embedded pieces.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a structural element for buildings or civil engineering and, more particularly, to a pre-embedded piece, a method for producing the pre-embedded piece, and reinforcing steel structures including the pre-embedded structure.[0003]2. Description of the Related Art[0004]Reinforced concrete structures have widely been used in many buildings and civil engineering. With reference to FIG. 1, a reinforcing steel structure 9 is prepared before grouting. The reinforcing steel structure 9 generally includes a plurality of main bars 9, a plurality of hooped columns 92, and a plurality of anchor bolts 93. The main bars 91 are arranged annularly. Each hooped column 92 is wound around the main bars 91 to shape the main bars 91. The anchor bolts 93 are coupled to a measuring board 94 mounted on top of the main bars 91. The measuring board 94 and the anchor bolts 93 are aligned with a space defined by the...

AI Technical Summary

Benefits of technology

The present invention provides a pre-embedded piece that allows a concrete aggregate mass to provide a strong grip on the pre-embedded piece, while also dispersing the force to prevent damage to the concrete. Additionally, the invention provides a reinforcing steel structure that includes the pre-embedded piece, ensuring reliable engagement with the concrete aggregate mass for safer use. The method of producing the pre-embedded piece is easy and can make efficient use of remaining reinforcing steel bar material, reducing waste and costs while also promoting green energy development.

Problems solved by technology

Furthermore, the body 931, which is generally made of low carbon steel, has a limited bent angle such that the effect of improvement to the engagement stability is limited.

Furthermore, when each anchor bolt 93 is subjected to a force, the force almost concentrates at the hooked portion 933 and causes breaking in a portion of the concrete aggregate mass S surrounding the hooked portion 933, adversely affecting the safety of the whole reinforcing steel structure 9.

Thus, the method for producing the anchor bolt 93 not only has great limitation to the size of the materials but is difficult to increase the yield.

Considerable costs and energy are involved in recycling the remainder, including transportation, sorting, and reproduction, which is a heavy burden to the person in the industry and the environment.
