The present invention relates to a speed construction method using a unit member in which a beam forming channel is integrally formed at the end of a hollow dry slab, and more particularly, a channel for forming a beam cross-section at the end of a hollow dry slab having a longitudinal span By constructing and prefabricating a unit member in advance, after installing the pillar, the unit member is continuously installed on the pillar without a separate beam construction step, and the unit member and the unit member are joined to form a beam, thereby simplifying construction and saving construction time. It relates to a speed construction method using a unit member in which a channel for forming a beam is integrally formed at the end of a hollow dry slab that can be shortened.

The biggest issue of recent construction companies and construction sites is off site construction. Although the dry method is being promoted to minimize on-site work, conventionally, concrete has been poured for slabs due to concerns about usability such as vibration and noise.

Therefore, there is a social consensus in favor of reducing labor and management costs by shortening the construction period even if some costs increase to minimize on-site work, but concrete is the cheapest material among construction materials and there is no substitute for it.

Recently, the interest of large construction companies in the housing market using modular architecture is increasing, and modular architecture is the most anticipated construction method that can minimize on-site work because 70-80% of the entire process is factory-manufactured and installed on site.

In the background art, '(a) installing both wall parts 200 on the bottom plate 100 in which the outer finishing plate 220 in the form of a vertical wall extending upward from the outer upper surface or the outer side is formed is installed on the bottom plate 100, (b) the wall In the right leg space (S) formed by holding the upper plate 300 between the inner upper surfaces of the part 200, the U-shaped ring-shaped inner reinforcing bars 210 drawn out from the upper surface of the wall and the upper plate end faces are overlapped with the right leg longitudinal reinforcing bars. (600), (c) pouring concrete in the right leg space (S) so that the right leg longitudinal reinforcing bar 600 is embedded in the U-shaped ring-shaped inner reinforcing bar, and the bottom plate ( The installation of the wall part 200 in 100) is the spherical recess of the concrete block chain concrete spherical recess 410 in which a spherical concave groove 411 is formed in the center of the upper surface and a horizontal upper surface part 412 is formed around the spherical concave groove. Concrete block chain concrete convex part ( 420) is arranged to be inserted into the spherical concave groove 411 of the concrete spherical concave portion 410, but the concrete spherical convex portion 420 is located at the lower end of the wall upper portion 421 and integrated with the wall portion 420. It includes the step of constructing, but the concrete spherical convex part is made by using the pre-fabricated concrete spherical recessed part as a match-casting formwork.

However, the background art has a problem in that it is not easy to join the joint.
