The longevity of a building has been affected more by the problem of the uniformity of the space which can not cope with the change of the life pattern according to the flow of the times along with the aging of the interior and exterior materials rather than the structural problem of the frame.

So far, it has been common to reconstruct the entire structure despite the sufficient lifetime of the frame, and this unreasonable reconstruction has caused another problem such as environmental pollution due to waste of resources and mass release of construction waste materials.

In order to solve these problems, recently, the cases of remodeling the buildings are increasing. Various efforts are being made to increase the lifespan of the buildings such as the policy support of the national government. It is to span the space so that space can be changed into various forms.

 That is, the space having the long span can be variously configured as a non-bearing wall such as a partition, so that it can cope with a change in the life pattern.

A variety of methods for long spaning of buildings have been studied. Among them, a method of increasing the rigidity while lightening the slabs has attracted considerable attention. For example, there is a hollow slab structure shown in FIG.

In the hollow slab, a hollow is formed at the central portion of the end face of the slab by using a light-weight molded body in the T-shaped deck plate so that the I-shaped cross-section has a continuous shape so that the flexural rigidity is increased but the weight is greatly reduced.

More specifically, FIG. 1 is a lightweight molding material assembly for fixedly mounting on a T-shaped deck plate and a lightweight slab structure using the same, which is disclosed in Registration No. 10-1176551 published on July 23, 2012 A plurality of T-shaped decks D are formed by fixing a plurality of T-shaped ribs D1 separated by a vertical portion D11 and a horizontal portion D12 to a T-shaped deck plate D protruding upward in a plurality of rows. (10) having a wide upper body (11) and a lower body (12), the body (10) being divided into two parts by forming a cut surface (14) A narrow support base 12 extending integrally from a lower portion of the upper main body 11, a fixing groove 13 formed on a bonding surface between the upper main body 11 and the support base 12, (15) formed on the cut surface (14), and two The horizontal portion D12 of the T-shaped rib D1 of the T-shaped deck plate D is inserted into the fixing groove 13 while the main body 10 is arranged facing the concave / .

The lightweight slab structure according to the prior art has a beneficial effect in that the lightweight molding material can be easily assembled to the T-shaped deck plate while reducing the number of parts. However, since the horizontal portion of the T- Since the fixing grooves 13 of the lightweight molding material into which the protrusions D12 are inserted are formed only on the joining surfaces of the upper main body 11 and the support base 12, This is because it is difficult to secure a space with respect to the lower end of the slab cross section, which makes it difficult to reinforce the bending stress caused by the reinforced concrete.

In addition, in the state where the two main bodies 10 are engaged only by the uneven portions 15, it can be easily separated by carelessness of the operator or by the concrete insertion pressure, so that there is a troublesome operation to install the anchor 30 , There is a problem in that the material and the shape of the lightweight molding material are limited.
