<p>The present invention relates to a concrete block with space to be installed at both ends of an I-steel beam; a steel beam formed by using such a concrete block with space to reduce the weight of the steel beam itself and facilitate the construction thereof; and a construction method of the steel beam, according to which a slab and a concrete block with space are combined into one body to prevent splitting of the slab and the concrete block with space and improve the quality. According to the present invention which relates to concrete block with space, manufacturing method of the concrete block with space, steel beam using the concrete block with space, and construction method of the steel beam, as a result of the inside the concrete block with space being empty, it is easy to lift and construct a steel beam by using such concrete blocks such that working hours and labor costs may be reduced and, further, the economical efficiency can be improved. In addition, as cast-in-situ concrete forming a slab is cast and cured in a concrete block with space, the slab and the concrete block with space are formed into one body, thereby preventing splitting of the slab and the concrete block with space.</p> |
