That is, since the short-length bars in the bar cannot be combined to the installation bars only by the rotation of the coupler, the overall durability, overall seismic performance, overall compressive strength, and overall tensile strength of the bar will decrease

Embodiment Construction

[0032] In the following, reference will be made to Figure 1 to Figure 9 The method of prefabricating steel mesh according to the present invention is described more specifically.

[0033] The present invention combines a plurality of steel bars used when building columns or beams (hereinafter collectively referred to as "columns"), that is, main steel bars 41, hoops 42 and hoops 43, thereby assembling a columnar reinforcement mesh 40 on the ground, and The reinforcement mesh 40 is moved to a position for construction by a crane, thereby easily interconnecting and combining each main reinforcement 41 of the reinforcement mesh 40 with each main reinforcement 91 protruding from the upper surface of the slab 90 .

[0034] All steel bars used in construction and civil engineering, such as threaded steel bars with spiral protrusions formed on their outer surfaces, annular steel bars with a plurality of annular protrusions formed on their outer surfaces, etc., can be used as steel b...

Abstract

The present invention relates to a prefabrication method for a rebar net that can easily connect and couple main bars of a rebar net and main bars of a slab that are installed in order to construct a column, a beam, or the like. To this end, the present invention provides a prefabrication method for a rebar net for arranging and installing a plurality of main bars using a jig, a support, and a fixed base, each of which has a coupler coupled to an end portion thereof, and connecting and coupling main bars of a rebar net and main bars of a slab, each of which has a plurality of hoops and stirrups coupled to the outer peripheral surface thereof, wherein each main bar of the rebar net is rotated to be inserted into and fastened to a coupler coupled to each main bar of the slab, thereby connecting and coupling the main bar of the rebar net and the main bar of the slab.

Description

technical field [0001] The present invention relates to a method of constructing steel mesh for use in columns or beams, and more particularly, to a method of prefabricating steel mesh that easily and conveniently assembles steel mesh to be installed to be configured as a column or beam Each main bar is interconnected and bonded to each main bar of the slab. Background technique [0002] Generally, when a high-rise building is constructed, the building is built layer by layer by pouring concrete on a foundation to create a floor, building a plurality of columns on the floor, and then pouring concrete thereon to create a slab. At this time, the columns or beams of the building (hereinafter collectively referred to as "columns") are constructed by embedding a plurality of steel bars into concrete so that the concrete has sufficient durability, sufficient seismic characteristics, sufficient tensile strength etc. [0003] At this time, in order to construct the column, a new s...
