Description

Slab-Case of solid water damage prevention

The present invention relates to a top-down evacuation shelter installed in the floor of a high-rise residential, commercial building evacuation in case of fire.

The Ministry of Land, Transport and Maritime Affairs installs top-down evacuation ports (covers, ladders, alarm systems) on the floors of balconies, etc.

This is a facility for making an opening of a standard that a person can escape on the floor, which is a boundary between the upper and lower layers, and is provided with a ladder that escapes in an emergency, and a cover covering the opening is formed.

The equipment as described above is a case 22, which is a frame like a box that is an inner wall in the opening of the building structure as shown in Fig. 5, a cover 23 for coupling and opening and closing with a hinge on the upper part of the case, a lower locking device, etc. The lower lid 24, which is opened and closed by the door, and one side wall of the frame are mounted by fixing bolts or the like to be folded and accommodated. It is installed on the floor by various construction methods such as prefilling and laying in the formwork according to the casting standard, building the opening surface on the floor and post-filling afterwards.

Here, if you look at the floor structure and construction process of the balcony and utility room, the reinforcing bar is laid on the formwork, the concrete is poured, and the slab forming process becomes a construction frame.

After a considerable period of time, the floor is constructed by the secondary process of waterproofing the slab and finishing the mortar and tiles after the desired number of building frames, so the openings formed on the floor also depend on the construction process. The thickness layer and the finishing thickness layer are overlapped.

In the above floor structure, when the evacuation port of FIG. 1 is buried in the slab floor, the case protrudes to the upper side by the height of the finishing work, and it is damaged or damaged regardless of the maintenance state by the construction process for a long time. Hazards exist, and construction that is embedded in the bottom opening of the concrete structure that is perforated largely in comparison with the size of the evacuation port inserts the evacuation port into the floor opening, joins and fixes the rebars, and the gap between the opening and the evacuation section. Many construction products are followed by the construction of backfilling materials such as concrete and finishing materials, and the construction structure becomes vulnerable due to cracks.

It is a slab layer evacuation case that prevents the body of the evacuation hole embedded in the floor from being damaged or damaged and proposes a solid waterproof coating.

In the slab case of the standard, which has a predetermined height lower than the thickness of the slab layer designed or constructed, the lumber is joined to the upper flange portion provided, and the plate is covered thereon, and then joined to the fixing member through each hole. It is a slab case of a solid waterproof, damage prevention, characterized in that the concrete is poured, fixed to the formwork.

The body of the evacuation hole embedded in the floor is not damaged or damaged, and there is an effect that a solid waterproof coating is constructed.

Hereinafter, with reference to the accompanying drawings, a solid waterproof and damage prevention slab case of the present invention will be described in detail.

1 and 2 is an exploded perspective view and a combined perspective view showing the configuration of the slab case in the evacuation hole is fixed to the formwork before the construction of the slab layer construction as a construction process is embedded.

The slab case (1) is formed in a square shape having an inner circumference as an opening in the upper flange portion (2) to the outside at the upper end, the lower flange portion (3) is formed to the outside at the lower end, the construction site It is manufactured to the height (preferably about 5 ~ 30mm) standard that is lower than the height of the slab layer or the designed slab layer of the floor.

And the slab case (1) the upper flange portion (2) is coupled to the lumber 4, such as wood, plastic, metal, etc. More preferably protrudes by a predetermined length in the outward direction than the outer end of the upper flange portion (2) The upper flange portion, which is enclosed in an enclosed form, is enclosed in a slab case (1), which covers the opening of the slab case (1), which is made of wood, plastic or metal of a standard including a horn (4) thereon. Using the holes 6 of 2), the holes 6 of the lumber 4, and the holes 6 of the plate 5, they are joined together by fixing members 7 such as bolts and nuts which can be subsequently disassembled. .

The slab case 1, the horn 4, and the plate 5 combined by the fixing member 7 as described above are placed in the formwork, and the holes 6 of the lower flange 3 of the slab case 1 Fixed with formwork and concrete is poured and embedded in the slab layer (8). After the concrete is cured and the formwork is removed, the dismantleable fixing member (7) and the plate (5) and the lumber (4) in turn When dismantled, the upper flange portion 2 of the slab case 1 is buried at a position lower than the height of the slab layer 8 formed as shown in FIG. 3, and the corner member 4 protruding outward from the upper flange portion 2. By doing so, the upper part of the slab layer 8 becomes the slab layer 8 having a structure in which the step 10 is extended from the outer side of the upper flange portion 2.

Of course, the slab 4 and the plate 5 embedded in the slab layer 8 together with the slab case 1 are preserved as it is for a considerable period before the start of the finishing work.

Figure 4 shows that the overlap of the extension case (9) made at the height of the finishing work on the upper part of the slab case (1) from which the plate material (5) and the lumber (4) is removed before finishing the overlapping work, the slab layer (8) When the watertight portion (2) and the extension case (9) overlap at the bottom of the step (10) wall of the slab layer (8) and the bottom of the slab layer (8) at the time of waterproofing, and the extension case ( As the waterproof mortar or the liquid is filled in the U-shaped groove formed by the outer wall of 9), it is possible to have a robust waterproof function at the joints of the connecting surface of the slab case 1 and the extension case 9 without breaking or damaging the waterproofing material. do.

After the construction as described above is made of mortar, tile finish, the ladder 25, the cover 23, etc. of the constituents of the evacuation port 21 is of course attached to each position.

Although the technical idea of the present invention has been described in detail according to the above-described preferred embodiment, the above-described embodiments are for the purpose of description and not of limitation.

In addition, it will be understood that those skilled in the art of the present invention can be variously changed and implemented within the scope of the technical idea of the present invention.
