Definitions

  • 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.
  • 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 main bars 91.
  • each anchor bolt 93 includes a body 931 having a smooth outer periphery. An end of the body 931 is processed to form a threaded portion 932.
  • a nut 95 threadedly engages with the threaded portion 932, and the threaded portion 932 extends through the measuring board 94 such that the body 931 and the nut 95 are located at a bottom side of the measuring board 94. Then, another nut 95 engages with a top end of the threaded portion 932.
  • each anchor bolt 93 is securely coupled to the measuring board 94, and the nuts 95 at the bottom side of the measuring board 94 are adjusted to level the measuring board 94.
  • the reinforcing steel structure 9 is poured with grout.
  • a concrete aggregate mass S is formed after the grout hardens.
  • a portion of the reinforcing steel structure 9 below the measuring board 94 (including the main bars 91, the hooped columns 92, and the bodies 931 of the anchor bolts 93) is covered by the concrete aggregate mass S.
  • the threaded portions 932 of the anchor bolts 93 extending beyond the top side of the measuring board 94 can be coupled to an object on the ground, such as a road lamp, mechanical equipment, or an abutment of a bridge.
  • each anchor bolt 93 since the outer periphery of the body 931 of each anchor bolt 93 is smooth, the other end of each anchor bolt 93 without the threaded portion 932 is bent to form a hooked portion 933 to prevent axial loosening of each anchor bolt 93 in the concrete aggregate mass S.
  • the hooked portions 933 of the anchor bolts 93 can improve the engagement stability with the concrete aggregate mass S, the concrete aggregate mass S almost cannot provide any force gripping and holding the smooth outer periphery of the body 931 of each anchor bolt 93. 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. In practice, it is not uncommon that the anchor bolts 93 loosen. 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.
  • the anchor bolt 93 since the anchor bolt 93 must include the hooked portion 933 that is formed by bending the other end of the body 931 after formation of the threaded portion 932 on the end of the body 931, the production method for the anchor bolt 93 is not convenient.
  • each anchor bolt 93 since the threaded portion 932 of each anchor bolt 93 is directly formed on the end of the body 931 by milling or thread rolling, the minimal outer diameter of the threaded portion 932 can only be smaller than the outer diameter of the body 931, leading to a weaker structural strength at the threaded portion 932 of each anchor bolt 93. Namely, only a body 931 having a larger outer diameter can be used to form the threaded portion 932 with the desired structural strength, leading to a waste of the materials of the body 931 covered by the concrete aggregate mass S and leading to difficulties in forming the hooked portion 933 by bending the other end of each anchor bolt 93.
  • 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.
  • each anchor bolt 93 is cut from a reinforcing steel bar of a pre-determined length according to the desired length of the anchor bolt 93, and a considerable amount of remainder of an insufficient length is generated during construction.
  • the remainder is generally recycled at a low price and forms reinforcing steel bars of the pre-determined length after melting. 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.
  • An objective of the present invention is to provide a pre-embedded piece permitting a concrete aggregate mass to provide an excellent gripping force on the pre-embedded piece. Furthermore, after the pre-embedded piece engages with the concrete aggregate mass, the force acting on the pre-embedded piece can be dispersed to avoid breaking in the concrete aggregate mass.
  • Another objective of the present invention is to provide a reinforcing steel structure including the pre-embedded piece for reliable engagement with the concrete aggregate mass to well maintain the use safety.
  • a further objective of the present invention is to provide a method for producing the pre-embedded piece.

  • 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.
  • the reinforcing steel bar and the screw rod can be made of different materials.
  • the screw rod can be made of stainless steel.
  • the other end of the reinforcing steel bar not connected to the screw rod can be bent to form a hooked portion.
  • the screw rod can include an outer threaded portion having a plurality of peaks and a plurality of roots.
  • the screw rod has a maximum outer diameter at the plurality of peaks and a minimal outer diameter at the plurality of roots.
  • the minimal outer diameter of the screw rod is substantially equal to an outer diameter of the body of the reinforcing steel bar.
  • the embossed portion can include a plurality of annular ridges and at least one longitudinal rib.
  • the plurality of annular ridges is parallel to each other.
  • the at least one longitudinal rib extends in a longitudinal direction of the reinforcing steel bar and connects the plurality of annular ridges.
  • a method for producing a pre-embedded piece according to the present invention includes preparing a reinforcing steel bar and a screw rod.
