Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a building evacuation device that is used by being buried in a veranda of a medium-to-high-rise residence or a medium-to-high-rise building.

Conventionally, this type of evacuation device has been made by hollowing out the area around the closed opening in the floor slab to expose the reinforcement, welding the anchors of the storage case to the reinforcement either directly or through auxiliary reinforcement, and applying mortar around the reinforcement. It was poured, buried and fixed.

However, the work of praying the floor slabs is complicated, wasting time and increasing lathe costs.Furthermore, during the praying work, cracks were formed in the floor slabs around the openings, reducing the strength and causing water to leak through the cracks. . Also, when a worker welds the anchors in a storage case to the reinforcement, one of the workers holds the storage case, and after matching the anchors in the storage case with the reinforcing bars, the welding worker welds the anchors and the reinforcement. This method has the disadvantage that it is difficult to align the storage case to a predetermined position and to level it horizontally or vertically, which wastes time.
The present invention has been made in view of the above circumstances, and aims to facilitate construction, shorten working time, and reduce construction costs.Moreover, the area around the opening is reinforced so that cracks will not occur. The present invention provides a building evacuation device.

To explain the structure of the present invention in detail with reference to the embodiments shown in the attached drawings, a floor slab 2 forming a veranda 1 is formed with a closing part 3 for connecting the upper and lower floors, and the upper surface side of the surrounding green area of the closing part 3 is A plurality of anchors 4 are provided along the circumference of the closed portion, and a support frame 5 is fixed to the anchors 4 by means such as welding. As mentioned above, the anchors 4 provided along the periphery of the opening 3 are for horizontally holding and fixing the storage case 8, which will be described later, and for fixing the support frame 5. These exposed ends are bent toward the entrance 3 side so that the upper edges of the bent portions 4a are located on the same horizontal plane.

The support frame 5 fixed to the anchor 4 is intended to protect the corners of the floor slab 2 that are most susceptible to damage, and is directed outward from the upper end of the vertical piece 6 that abuts the side wall of the closure 3. It is constructed by framing a frame material formed into a substantially L-shaped cross section with a layered portion 7 horizontally protruding from the anchor 4, and the pupil portion 7 of the frame material is connected to the upper edge of the bent portion 4a of the anchor 4. After being re-laid, it is fixed by welding or other appropriate means.

A storage case 8 that stores evacuation equipment 16, which will be described later, is stored and fixed in the support frame 5 configured in this manner.

This storage case 8 includes a storage frame 9 that penetrates vertically, and an upper lid body 10 that opens and closes the upper and lower entrances of the storage frame 9.
A lower lid body 11 is pivotally supported to be openable and closable, and a locking protrusion having an approximately L-shaped cross section and an outward protrusion 13 is provided on the four peripheries of the side wall 12 of the storage frame 9 of the storage case 8. A plurality of locking protrusions 14 are provided, and the respective locking protrusions 14 are attached horizontally to each other. The storage case 8 configured in this manner is inserted into the closed portion 3 of the floor slab 2 from the floor side, and the locking protrusion 14 provided on the storage case 8 is placed on the podium portion 7 of the support frame 5. By pouring mortar 15 between the storage case 8 and the closing part 3 and on the floor side of the floor slab 2 and solidifying it, the storage case 8 can be fixedly attached.

The evacuation equipment 16 stored in the storage case 8 installed and fixed at the entrance 3 formed in the floor slab 2 of the veranda 1 in this way is a plurality of hollow sliding villages 17 of different shapes.
17 in a telescopic manner, and connect the base side of the hollow sliding punch 17 located at the top to the handrail side of the veranda 1 of the storage case 8 & to the bracket 18 fixed inside the side wall 12. It is pivotally connected via a support shaft 19, and when in use,
The evacuation equipment 16 extended to the lower floor is located on the handrail side of the veranda and suspended from the storage case 8.

When it is inconvenient, the hollow sliding punches 17...17 are telescopically retracted, rotated about the support shaft 19, and stored in the storage case 8 in a horizontal position. The present invention has the above-mentioned configuration, and includes an anchor 4 with an exposed end on the periphery of the closed part of the floor slab 2, and the exposed end of the anchor 4 is bent. Since the horizontal position is leveled, the storage case 8 can be reliably fixed horizontally regardless of the unevenness or inclination of the floor slab 2 itself.

Further, a flat plate-shaped mounting portion 7 of the support frame 5 is fixed via an anchor 4 to the surrounding area of the entrance portion 3 formed on the floor slab 2.
On top of the storage case 8, a plurality of locking protrusions 14 provided horizontally to each other are folded and fixed, so there is no need to worry about the complicated work of constructing a floor slab to install the storage case 8. There is no need for manual support, positioning, horizontal leveling, or vertical leveling of the storage frame, making the installation process easy and quick, and can be done by one person. , construction costs and labor costs can be significantly reduced. In addition, the periphery of the opening 3 formed in the floor slab 2 is reinforced with the support frame 5, so
This prevents cracks from occurring in the floor slab due to impact when the evacuation equipment is raised and lowered, and concerns about water leakage are also eliminated.
