Description

An assembled steel column in which vertical steel members are restrained by a plurality of horizontal diaphragm plates {Steel Columns Using Diaphragm plate and Vetical steel member}

The present invention relates to a prefabricated steel column in which vertical steel is restrained by a plurality of horizontal diaphragm plates. More specifically, a plurality of horizontal diaphragm plates are configured to correspond to the cross section of the girder to facilitate connection with the girder and penetrate the cross section of the column. Stress can be transmitted by a plurality of horizontal diaphragm plates without doing so, and by constructing a plurality of vertical steel members on the outside of the horizontal diaphragm plate to be restrained by the horizontal diaphragm plate, the rigidity of the assembled steel can be increased. It relates to an assembled steel column in which vertical steel members are restrained by a plurality of horizontal diaphragm plates.

A column refers to a vertical structural element that transfers the load applied from the top to the lower part through axial compression. In particular, in reinforced concrete buildings, the pillar plays the role of receiving the load transmitted from the upper slab or beam and transferring it to the foundation below. It is a very important part that determines the safety of the entire completed structure.

These columns are completed by manually placing reinforcing bars at the location where they are to be installed, then pouring and curing concrete. In this case, there is a problem of delay in construction period because the placement work relies only on manpower, and in the case of buildings with high floor heights, separate installation is required. After installing a temporary workbench, workers have to stand on the workbench and perform difficult reinforcement work for a long time, so there is a constant problem of safety accidents.

Taking these problems into consideration, recent columns are assembled by combining reinforcing bars at the construction site to assemble the reinforcing bar network. The completed reinforcing bar network is lifted by a crane and then transported to the location where the column is to be installed. It is generally constructed using the reinforcing bar mesh pre-assembly method, which involves combining the assembled reinforcing bar networks and then pouring and curing concrete. However, the conventional rebar network pre-assembly method as described above had a problem in that it was difficult to join steel beams or reinforced concrete beams because there was no diaphragm for connecting separate beams to the pre-assembled rebar network.

The technology behind the present invention includes Patent Registration No. 1577539, “Reinforcing bar pre-assembled column using threaded rebar with diaphragm and split nut” (Patent Document 1). In the above background technology, threaded reinforcing bars are arranged vertically and spaced apart from each other to serve as main bars of a column, and have threads formed on the outer periphery; The number corresponding to the threaded reinforcing bar is plate-shaped, and each protrudes outward from the outer end, forming a joint formed by a hole in the coupling hole. The coupling hole is inserted into the threaded reinforcing bar, and the threaded reinforcing bar is divided into two halves at a certain height and joined on both sides of the threaded reinforcing bar. It consists of an upper plate fixed with a type nut, and a coupling part in the shape of a plate of the same shape as the upper plate, each protruding outward from the outer end, and formed by a coupling hole, and a coupling hole is formed in the threaded reinforcing bar to be spaced downward at a certain distance from the upper plate. A diaphragm consisting of a lower plate that is fitted and secured with a split nut that is bisected and joined on both sides of the threaded rebar; It was made to facilitate the joining of the beam by including a strip of reinforcing bars joined horizontally at regular intervals in the height direction of the threaded reinforcing bars to surround the outside of the threaded reinforcing bars. However, the background technology only applies to the upper and lower parts of the cross section of the beam. Because the plate is composed of a diaphragm, it is not easy to transmit stress in the center of the cross section of the beam, and there is a problem in assembling the plate to the threaded rebar and split nut.
