い。 The pit device A is constructed as described above, but if this pit device A is to be installed on a concrete floor, concrete 31 is poured directly around the pit device A to form the floor 32. . In this case, the pit device A can be buried in the floor 32 in one concrete pouring operation, so the construction period can be shortened compared to the conventional example. Since the attachment to the support device 1 of No. 3 can be easily performed separately, the number of assembly steps is reduced, and the manufacturing cost of the pit device A can be reduced. Further, the duct 4 is reinforced by an inward flange 22 that is integrally connected to the opening edge, and the outer surface near the opening edge is closely supported by the inner surface of the vertical support piece 27 of the pit frame 3, so that it can be concrete-cast. The duct 4 will not be deformed during installation.

れはない。 As described above, according to the present invention, there is a support device disposed on the foundation on both outside sides of a channel-shaped pit, and a pair of pits connected and supported by the support device and extending respectively along both opening edges of the pit. Consisting of a frame and a duct suspended by the pit frame,
The duct is composed of a channel-shaped duct main body with an open upper surface, and a pair of inward flanges integrally connected to both opening edges of the duct main body, and each of the pit frames is connected to the opening in the floor. A pit frame main body having a substantially L-shaped cross section on which the side edge of the pit cover can be placed as well as edging the edge, and a horizontal support extending substantially horizontally from the inner edge of the pit frame main body and abutting against the upper surface of the inward flange. and a vertical support piece that hangs down from the inner edge of the pit frame body and abuts against the outer surface of the side wall of the duct body that is continuous with the inward flange, and each of the horizontal support pieces and the corresponding inward Since the flanges are integrally connected to each other via a coupling device independent of the support device, a pit can be easily formed by suspending the duct from the pit frame supported on the foundation via the support device. Therefore, if the floor is made of concrete, the work of constructing the formwork for forming the pit can be omitted, greatly shortening the construction period, and even if a lightweight floor is used, the pit Since the weight of the frame and duct can be stably supported on the foundation via the support device, there is no risk that the duct will be deformed due to distortion of wooden floor components such as joists.

できる。 In particular, the horizontal and vertical support pieces of the pit frame are in close contact with the corner portion formed by the inward flange of the duct body and the side wall connected to the flange, thereby regulating the deformation movement of the corner portion and increasing its rigidity. Therefore, together with the reinforcing effect of the inward flange itself, it can greatly contribute to increasing the strength of the opening edge of the duct main body, and therefore the joint portion between the inward flange and the horizontal support piece The duct body can be easily suspended from the pit frame through the . Moreover, since the inward flange at the opening edge of the duct main body can be covered with a good appearance by the horizontal support piece, there is no fear that the external appearance of the pit will be impaired by the flange, and the opening edge of the floor can be covered with a good appearance. A pitt frame for edging is
This serves both as a edging means and a reinforcing means for the opening edge of the duct main body, which can contribute to the simplification of the structure. Furthermore, since the coupling between each horizontal support piece and the inward flange is independent from the support device, if the duct is set in the pit frame in advance, the pit frame can be installed simply by retrofitting the pit frame to the support device. It becomes possible to assemble the device quickly and easily, and it can contribute to improving the efficiency of the assembly work.
