There were problems such as the work being difficult and requiring a lot of time and effort, and the work being often done at heights, which was dangerous and resulting in many falling accidents. Furthermore, as shown in FIG. 4(c), the heat insulating exterior material f is made by riveting heat insulating material g to the outer peripheral surface of the duct, assembling wooden frames at regular intervals and attaching material 1. Since it has a multi-layered structure, which consists of wrapping waterproof paper J, pasting it with lath K, applying mortarno, and covering it with plaster M, it is not only time-consuming but also increases equipment costs.

A slab 4 is formed by placing concrete 3 in parallel on the upper surface. An equipment duct can be formed by inserting a metal cylindrical body 5, which is a duct body, and a heat insulating material 6 wrapped around the outside at a desired location in the cylindrical beam 1. In this case, as shown in FIG. 2, a metal plate to which a heat insulating material 6 is attached is rolled up to form a cylinder 5'.
After inserting this cylindrical body into the cylindrical beam 1, the joints of the metal plates may be welded 7 to form an equipment duct. In addition to using a glass fiber sheet as the heat insulating material 6, it is also possible to attach a foamed material in advance by spraying it to an appropriate thickness, which is a method suitable for mass production. be. When the post-cast concrete 3 is placed, a pipe 8 for electrical wiring is buried, and an embedded box 9 for a socket can be provided on the upper surface. 10 is a ceiling material, which can be attached via the ceiling base material I+ fixed to the tightening belt 2. 12

。[Effects of the Invention] As explained above, according to the present invention, an equipment duct is formed by inserting a cylindrical body coated with a heat insulating material on the outside into the space of a hollow slab. There is no need to secure space for installation of equipment ducts, the ceiling height remains the same as before, making it possible to build buildings with lower floor heights, and there is no need to install hanging materials, making construction easier and less labor-intensive. It is safe because there is little work to be done at heights, and has excellent effects such as preventing falling accidents. In addition, in the case of the present invention, the exterior material only needs to be a heat insulating material, so there is no need for a complex multi-layer structure unlike conventional heat insulation exterior materials, which saves labor and improves construction efficiency. It is possible to reduce costs.
