[Problems to be Solved by the Invention] However, these evacuation devices 5 are installed in places exposed to the outside of the building and exposed to wind and rain, such as the floor 3 of the balcony 2, and various constituent members are made of steel. Since these parts were made of wood, corrosion may occur over time, and rainwater may fall with the rust to the floor below, and depending on the degree of corrosion, there may be doubts as to whether or not it can actually function as an evacuation device 5. It was in a situation where it was installed as is. In addition, when we investigated the evacuation device 5 that had been installed for many years, we found that
As shown in FIG. 6, the outer periphery A1 of the upper lid 9, especially its outer periphery back surface B, and the outer periphery C of the upper edge frame 8 are the most corroded.
Furthermore, corrosion was also observed at the boundary between the upper edge frame 8 and the upper end of the storage frame 7. In this way, it is necessary to repair some of the severely corroded evacuation equipment or replace it with new evacuation equipment, but no matter which replacement method is carried out, it is difficult to do so in a building where people are currently living on both the upper and lower floors. Place the storage frame 7 of the evacuation device 5 on the floor 3.
The work of removing the storage frame 7 from the hole 4 in the floor 3 is difficult, and in order to reinstall the storage frame 7 in the hole 4 in the floor 3, the concrete near the hole 4 has to be ground and the reinforcing bars partially changed. expose it,
There were problems such as the very complicated work of having to weld the anchors for attaching the storage frame. The present invention was made in view of the above circumstances, and an object of the present invention is to provide an installation structure for an evacuation device that is easy to install.

[Means to solve the problem]

In order to achieve the above object, the evacuation device installation structure according to the present invention includes a plurality of anchor bolts installed approximately horizontally on the inner wall surface of a hole in the floor, and a plurality of brackets provided with slits on the lower end side. The storage frame is attached to the outer wall surface of the storage frame so as to be rotatable in a substantially vertical plane, and the storage frame is fitted into the opening from above.
It is installed by inserting the slit of the bracket into the anchor bolt from above and spanning it, and then tightening the bracket to the anchor bolt with a nut.

[For production]

The installation structure of the evacuation device configured as above is such that multiple brackets attached to the storage frame are straddled over multiple anchor bolts attached to the inner wall surface of the hole in the floor and fixed with nuts. With this design, the storage frame can be easily installed inside the hole by simply driving the anchor bolt into the inside wall of the hole, that is, into the concrete, and the concrete near the hole in the floor can be sanded. There is no need to perform the extremely complicated work of exposing the reinforcing bars and welding anchors for attaching the storage frame to them. Moreover, when fitting the storage frame into the hole from above, the bracket is rotated and adjusted according to the position of the anchor bolt, and the slit in the bracket is inserted and spanned over the anchor bolt, so the anchor bolt is installed at the correct position. These anchor bolts can be driven and fixed in locations that avoid the concrete reinforcement of the floor. In addition, the bracket that spans the anchor bolt through the slit can be moved and rotated in the vertical direction with respect to the anchor bolt, so the mounting posture such as the installation height and horizontality of the storage frame within the hole can be adjusted. can be adjusted freely. Furthermore, by loosening the fixing nuts, the storage frame installed in the hole can be easily removed upwards as necessary.
