Description

  The present invention relates to a reinforcing and fixing structure for reinforcing bars, and more particularly, to a reinforcing and fixing structure for reinforcing bars that is fastened by being fastened to a place where longitudinal column bars and transverse band bars intersect.

  In addition to selecting and using seismic foundations, the strength to support beam columns was also an important condition for the earthquake resistance of buildings. In general, the beam column of a building has been provided with a supporting action by placing concrete after placing a plurality of reinforcing bars. For this reason, the strength of the beam column is related to the column reinforcement used for the reinforcing bar rod, the size of the reinforcement, the binding method of the reinforcement, the size of the pitch of the reinforcement or the reinforcement.

  Because the energy released by earthquakes is very large and can cause catastrophic destruction, countries located on the seismic zone provide for the seismic strength of buildings to prevent the loss of life and property due to earthquakes. Yes.

  Conventional beam columns have been formed by placing concrete after placing rebar. A large number of column reinforcements are installed on the reinforcing bar, and a plurality of strips are installed outside the column reinforcement at intervals. The crossing points of the column reinforcements and straps are fixed by cable ties. The stirrups and the binding wires prevented the column bars from displacing in the radial direction when sag occurred.

In general, when fixing the location where the column and band bars intersect with the binding line, bind the portion where the column and band bars intersect directly with the binding line, and then use a tool such as a hacker to connect both ends of the binding line. Tie up and fix the point where the column and tie line intersect.
However, in such a method, selection of the diameter of the binding wire is one of the conditions for determining the strength. Therefore, in order to obtain a large rigidity, when selecting and using a binding wire having a large diameter, work is required. It was not easy for the performer to fix the points where the column bars and the strips intersect by binding the ends of the binding line with a tool. In addition, when selecting and using a binding wire with a smaller diameter, it was possible to easily tie the ends of the binding wire using a tool and bind the crossing point between the column and the band. The strength was not so high and the seismic effect was not favorable.

  Therefore, the present inventor has developed a reinforcing bar fastening and fixing structure of the present invention that improves the problems of the prior art that have occurred when binding the places where the column bars and the band bars intersect with the binding line.

  It is an object of the present invention to insert a clamper into a clamping piece and then screw a screwing member into both ends of the clamper to bind and firmly fix the places where the column and strips cross vertically and horizontally. It is another object of the present invention to provide a reinforcing bar fastening and fixing structure that can reduce construction time and labor.

  In order to solve the above-described problem, according to the first aspect of the present invention, there is provided a reinforcing bar fastening and fixing structure including a clamper, a clamping piece, and two screwing members, and the clamper has a horseshoe shape. Two rods corresponding to each other, each of the two rods has a threaded portion, each of the clamping pieces has two through holes, and each of the rods is inserted into the through hole, The screw member is screwed to the threaded portion of the rod, and the clamper and the clamping piece are turned around at a position where the column and the strip are crossed vertically and horizontally. There is provided a reinforcing bar tightening and fixing structure characterized in that a portion intersecting vertically and horizontally is firmly fixed.

  It is preferable that a part of a portion where the column bars and the band bars intersect vertically and horizontally is bound by the clamper, the clamping piece, and the screwing member.

  A part of the portion where the column bars and the band bars intersect vertically and horizontally is bound by the clamper, the clamping piece, and the screwing member, and the remaining part of the portion where the column bars and the band bars intersect vertically and horizontally Are preferably bound by a binding wire.

  In the reinforcing and fixing structure for reinforcing bars according to the present invention, the portions where the column bars and the band bars intersect vertically and horizontally are bundled by the clamper and the clamping piece, and the column bars and the band bars are firmly bound by the screwing of the screw members. Therefore, even if it receives force, it is not separated, and the structural strength of the beam column formed thereby can be improved and the seismic strength of the building can be improved. Since the method of attaching and fixing the clamping pieces and the screwing members is simple, the construction time and labor can be reduced.
