Description

TECHNICAL FIELD The present invention relates to a partition fireproof wall installed inside a parking device.

Fireproof performance standards are stipulated by law for partition walls that divide spaces inside buildings. For example, in a parking device with a parking area of 1500 m ² or more, it is necessary to partition with walls that are fire resistant for 1 hour. Such a partition wall is hereinafter referred to as a "partition fireproof wall".

Conventionally, such partition fireproof walls have used autoclaved light-weight concrete (hereinafter referred to as "ALC material"). Partition fireproof walls using ALC material are disclosed in Patent Documents 1 and 2, for example.

The "refractory-coated runner member" of Patent Document 1 has a heat-expandable fire-resistant layer laminated on the surface of a runner member that fixes a concrete panel partition material (ALC material).

The "fireproof wall structure of the partition wall" of Patent Document 2 includes an upper runner and a lower runner attached to the ceiling surface and the floor surface, a plurality of studs erected between them, and both sides of each stud. and attached left and right refractory materials (ALC materials). The refractory material consists of a lower refractory board made of calcium silicate board and an upper refractory board. A thermally expandable fireproof material that expands when heated is inserted between the upper runner and the ceiling surface or the lower surface of the beam.

JP-A-2003-56098 JP 2012-52333 A

The ALC material is a lightweight cellular concrete that has been steam cured at high temperature and pressure, is produced in factories, and is commercially available in specified sizes. For example, a conventional partition fire-resistant wall installed inside a parking device uses an ALC material having a thickness of 75 mm, a width of 600 mm, a length of 4000 mm, and a weight of about 124 kg.
However, partition fireproof walls using ALC materials have the following problems.

(1) The partition fireproof wall protrudes into one (or both) of the parking compartments in plan view from the position of the pillars and beams, reducing the effective area of the parking compartment.
The installation position of the partition fireproof wall is the surface of the pillars and beams that form the frame of the parking device. When installing a partition refractory wall on the surface of a column or beam, fix a base material (e.g., stud) to the outer surface of the column or beam, and place a plurality of rectangular ALC materials adjacent to each other on the outer side of the base material. fixed. Therefore, the base material and the ALC material protrude from the outer surfaces of the pillars and beams into one (or both) of the parking compartments in a plan view, and the effective area of the parking compartment is narrowed. This protrusion amount is, for example, 80 mm or more.

In addition, in order to reduce the amount of protrusion, when the base material or ALC material is fixed inside the column and beam in plan view, there are intermediate columns and braces between the column and the beam, so the ALC material is rectangular. It is necessary to divide it into shapes other than the above, and the gaps in the ALC material are further increased, resulting in a complicated structure.

(2) The gap between adjacent ALC materials is large.
It is necessary to set a large gap between adjacent ALC materials in consideration of thermal expansion at the time of fire. In addition, due to the deformation of the columns and beams during an earthquake, this gap is partly larger than at the time of installation.
Therefore, in the event of a fire, the base material is overheated through this gap and thermally deformed, and there is a possibility that the flame or smoke may enter the adjacent parking compartment through the gap.
In order to avoid this problem, if a thermally expandable fireproof layer or thermally expandable fireproof material is provided before and after the gap as in Patent Documents 1 and 2, the structure of the partition fireproof wall becomes more complicated.

SUMMARY OF THE INVENTION The present invention has been devised to solve the above problems. That is, the object of the present invention is to increase the effective area of the parking space by reducing the portions protruding into the parking space from the outer surfaces of the pillars and beams, and to greatly reduce the gaps through which flames and smoke enter the adjacent parking space during a fire. To provide a partition fireproof wall which can be reduced to

According to the present invention, a partition fire-resistant wall installed along a steel structure located at the boundary of a plurality of parking rooms,
a steel frame that constitutes the steel structure;
a plurality of support metal fittings fixed to the steel frame along the border at intervals inside the steel frame structure in a plan view;
a heat-resistant panel having no opening that is fixed to the support fitting inside the plan view and closes the opening of the steel frame structure along the boundary;
a fireproof coating continuously formed on the outer surface of the steel frame, the support bracket, and the heat-resistant panel ;
The support fitting is divided at a position where it abuts on the pillar, beam, or brace located at the boundary of the parking room, and one side in the horizontal direction orthogonal to the boundary is the pillar or beam. positioned substantially flush with the horizontal end face;
A partition fire-resistant wall is provided in which the heat-resistant panel is not divided at the brace portion and is positioned continuously .

According to the present invention, since the support bracket and the heat-resistant panel are fixed inside the steel frame structure in plan view, part (or all) of the fireproof coating formed on the outer surface of the heat-resistant panel is inside the steel frame structure in plan view. Located in Therefore, of the fireproof coating on the outer surface of the heat-resistant panel, the portion that protrudes into the parking compartment from the position of the opening of the steel frame that constitutes the steel frame structure does not exist or is less than the thickness of the fireproof coating (for example, less than 30 mm). The effective area of the parking room can be increased by greatly reducing the protruding part from the parking space.

In addition, since the fireproof coating is continuously formed on the outer surfaces of the steel frame, the support fittings, and the heat-resistant panel, no gaps are formed in the fireproof coating. In addition, since fire-resistant coatings are formed on both sides of the heat-resistant panel without openings, even if one fire-resistant coating is cracked due to an earthquake or the like, a gap penetrating the other fire-resistant coating and the heat-resistant panel cannot be created.
Therefore, it is possible to greatly reduce gaps through which flames and smoke enter adjacent parking compartments in the event of a fire.

Parking device.
The parking device 100 of the present invention is not limited to this example, and may be any other type of parking device.

In FIG. 1, a cage 5 carries a pallet 3 thereon and ascends and descends a hoistway 4 between a storage shelf 6 and a loading/unloading floor 7 . A plurality of storage racks 6 are provided along the hoistway 4 . The pallet 3 that has been moved from the storage shelf 6 onto the cage descends on the hoistway 4 toward the loading/unloading floor 7. - 特許庁

At the center of the cage 5, an elevating and rotating device 5a is provided. The elevating and turning device 5a also serves as a traversing device for traversing the pallet 3 between the storage shelf 6 and the cage 5. As shown in FIG. At the time of loading and unloading, the pallet 3 is rotated horizontally by 90 degrees by the lifting/lowering device 5a so that the longitudinal direction of the vehicle 1 is directed from the storage direction X to the loading/unloading direction Y. As shown in FIG.

In FIG. 2, 8 is an entrance/exit door, 9 is an outer wall, and 10 is a steel structure.
The steel frame 12 forming the steel frame structure 10 has columns 13, beams 14, and braces (not shown) that function as the frame of the parking device 100 in this example. The steel structure 10 may also have intermediate columns and intermediate beams (not shown).

In FIG. 2, a partition refractory wall 20 according to the present invention is installed along a steel structure 10A located at the junction AA of a plurality of parking compartments (in this example two elevator car parks 90). For example, if the parking area of one or both of the elevator parking devices 90 exceeds a predetermined area (for example, 1500 m ² ), the partition fire-resistant wall 20 with one-hour fire-resistant performance is required.
Hereinafter, the steel frame structure 10A located at the boundary line AA is simply referred to as the "partition steel frame structure 10A" when necessary.

FIG. 3 is a partially enlarged view (A) of FIG. 2 showing the first embodiment of the partition fireproof wall 20, and a view (B) taken along line BB of FIG.
In this figure, the partition fire-resistant wall 20 has a steel frame 12A that constitutes the partition steel-frame structure 10A, a plurality of support fittings 30, a heat-resistant panel 40 without openings, and a fire-resistant coating 50. FIG.

In this example, the steel frame 12A that constitutes the partition steel frame structure 10A is the column 13A, the beam 14A, and the brace 15A (brace) located at the boundary line AA. may
Hereinafter, the steel frames 12A, columns 13A, beams 14A, and braces 15A are respectively referred to as "partition steel frames 12A,""partition columns 13A,""partition beams 14A," and "partition braces 15A" when necessary.

A plurality of support fittings 30 are fixed to the steel frame 12A (partition steel frame 12A) inside the partition steel frame structure 10A in plan view at intervals along the boundary line AA. In this example, the partition steel frames 12A to which the support metal fittings 30 are fixed are the partition columns 13A and the partition braces 15A, but they may be the partition beams 14A.
The intervals between the plurality of support fittings 30 are preferably set so that the heat-resistant panel 40 can withstand the pressure (for example, 1000 Pa) received during firefighting work in the event of a fire, and have pressure resistance that does not cause large deformation. This distance is, for example, 700-1000 mm.

The heat-resistant panel 40 is fixed to the support fitting 30 inside the steel partition structure 10A in plan view, and closes the opening 11 of the steel partition structure 10A along the boundary line AA.
The openings 11 of the partition steel frame structure 10A are, in this example, a rectangular opening 11a surrounded by the partition pillar 13A and the partition beam 14A, and a triangular opening 11b surrounded by the partition pillar 13A, the partition beam 14A and the partition brace 15A. Consists of Note that the opening 11 is not limited to a rectangular shape or a triangular shape, and may have other shapes.

The fireproof coating 50 is continuously formed on the outer surfaces of the partition steel frame 12A, the support bracket 30, and the heat-resistant panel 40. As shown in FIG. Hereinafter, the refractory coating 50 will be referred to as a "partition coating 50" when necessary.

FIG. 4 is an enlarged view (A) of portion C in FIG. 3(A) and an enlarged view (B) of portion D in FIG. 3(B). 5 is a view taken along the line EE in FIG. 3(B).

In FIGS. 4A and 4B, the outer wall 9 is a building incombustible board or steel plate, and a fireproof coating 51 is continuously formed on the inner surface thereof. The fireproof coating 51 of the outer wall 9 is hereinafter referred to as the "outer wall coating 51".
The steel plate of the outer wall 9 is a corrugated plate whose cross section is bent into a square wave shape or a circular wave shape, and is preferably fixed to the steel frame 12 by a vertical construction method in which the wave bent portions are positioned vertically.
The outer wall covering 51 is sprayed rock wool made of a mixture of rock wool and cement, and is formed by spraying the outer surface of the outer wall 9 by a spraying method. The thickness of the outer wall coating 51 is preferably 30 mm or more.
It has already been confirmed that the outer wall 9 having the outer wall coating 51 configured as described above has a fire resistance performance of "1 hour fire resistance" according to the Building Standards Law if the thickness of the outer wall coating 51 is 30 mm or more.

In FIGS. 4 and 5, the partition column 13A constituting the partition steel frame structure 10A is H-shaped steel, but other type steel may be used. The partition beam 14A is also made of H-shaped steel in this example, but may be made of other shaped steel.

The support fitting 30 is, for example, shaped steel such as lip channel steel (C channel steel), angle material, channel material, etc., but may be other members (eg, square bar, round bar, deformed steel bar). The support metal fittings 30 are preferably fixed to the partition pillars 13A, the partition beams 14A, and the partition braces 15A by welding, but may be fixed by screws (not shown) or bolts and nuts.
In this example, the plurality of support fittings 30 are fixed to the partition beam 14A or the partition brace 15A at intervals in the horizontal direction inside the openings 11 (rectangular opening 11a and triangular opening 11b).
A plurality of support fittings 30 may be fixed to the partition column 13A and the partition brace 15A at intervals in the vertical direction.

The heat-resistant panel 40 is preferably a steel plate that has no openings and has heat resistance and pressure resistance. The heat resistance preferably withstands the maximum temperature (for example, 300° C.) heated through the fire resistant coating 50 in the event of a fire and does not cause large deformation. In addition, it is preferable that the pressure resistance withstands the pressure (for example, 1000 Pa) received during firefighting work in the event of a fire while being supported by the plurality of support fittings 30, and that large deformation does not occur.
Specifically, the heat-resistant panel 40 is preferably a heat-resistant steel plate (corrugated plate) whose cross section is bent into a square wave shape or a circular wave shape. Also, in this example, the bent portions of the corrugated plate are fixed to the support metal fittings 30 by a laterally extending construction method.
Moreover, it is preferable that the heat-resistant panel 40 does not have an opening (gap) in its intermediate portion.
One opening 11 is preferably closed with a single heat-resistant panel 40, but a plurality of heat-resistant panels 40 may be partially overlapped and used.

With the above-described configuration, the bent portions of the corrugated plate extend horizontally, so it is possible to prevent or reduce the flow of the fireproof coating 50 (partition coating 50) by the spraying method before curing and falling off after curing. Moreover, since the heat-resistant panel 40 does not have an opening (gap), even if a part of the partition covering 50 is cracked, a gap penetrating both sides of the partition fire-resistant wall 20 can be prevented from being generated.

In this example, both horizontal ends or an intermediate portion of the heat-resistant panel 40 are fixed to the support fittings 30 inside the openings 11 (rectangular opening 11a and triangular opening 11b). Both ends or an intermediate portion of the heat-resistant panel 40 in the vertical direction may be fixed to the support metal fittings 30 fixed to the partition pillar 13A and the partition brace 15A.
The heat-resistant panel 40 is preferably fixed to the support bracket 30 by screws (not shown), but bolts and nuts or welding may also be used.
The positions of the support metal fittings 30 are set so that the outer surfaces (both sides in the figure) of the heat-resistant panel 40 are located inside the partition steel frame structure 10A in a plan view.

4 and 5, the partition coating 50 is sprayed rock wool made of a mixture of rock wool and cement, and is sprayed onto the outer surfaces of the partition steel frame 12A, the support bracket 30, and the heat-resistant panel 40 by a spraying method. formed. The partition coating 50 preferably has a thickness of 30 mm or more.
Before spraying the sprayed rock wool, it is preferable to apply an adhesive to the outer surfaces of the partition steel frame 12A, the support fitting 30, and the heat-resistant panel 40 to increase the bonding strength of the sprayed rock wool.
After forming the partition coating 50 on both sides of the heat-resistant panel 40 by the spraying method, it is preferable to flatten the surface of the partition coating 50 by pressing with a trowel or the like.

Spraying Rock wool is sprayed by, for example, pumping a mixture of rock wool and cement to a predetermined height using a pump located on the ground floor.

As shown in FIGS. 4 and 5, the positions of the support metal fittings 30 and the heat-resistant panels 40 can be set so that the outer surface of the partition coating 50 of the opening 11 is located inside the partition steel frame structure 10A in plan view. preferable.

According to the above-described configuration, if the thickness of the partition coating 50 is 30 mm or more, it can be said that, like the outer wall 9, it has the fire resistance performance of "one hour fire resistance" according to the Building Standards Law.

According to the above-described first embodiment of the present invention, the support metal fittings 30 and the heat-resistant panel 40 are fixed inside the partition steel frame structure 10A in plan view, so that one part of the partition covering 50 formed on the outer surface of the heat-resistant panel 40 A part (or all) is located inside the partition steel frame structure 10A in a plan view.
Therefore, the portion of the partition coating 50 that protrudes from the position of the opening 11 of the steel frame 12A into the parking compartment is none or less than the thickness of the partition coating 50 (for example, less than 30 mm), and the portion that protrudes from the steel frame structure 10A is The effective area of the parking room can be increased by greatly reducing it.

Moreover, since the partition coating 50 is continuously formed on the outer surfaces of the partition steel frame 12A, the support metal fittings 30, and the heat-resistant panel 40, no gap is generated in the partition coating 50. - 特許庁Moreover, since the partition coating 50 is formed on both sides of the heat-resistant panel 40 without openings, even if one of the partition coatings 50 is cracked due to an earthquake or the like, a gap penetrating the other partition coating 50 and the heat-resistant panel 40 cannot be created. .
Therefore, it is possible to greatly reduce gaps through which flames and smoke enter adjacent parking compartments in the event of a fire.

FIG. 6 is a view similar to FIG. 4 showing a second embodiment of the partition refractory wall 20. As shown in FIG.
In this figure, the support bracket 30 is positioned at or near the boundary line AA, and a pair of heat-resistant panels 40 are fixed to the outside of the support bracket 30, respectively. In this figure, the support fitting 30 may be single or plural in the thickness direction.
A pair of heat-resistant panels 40 are fixed with an interval L in the thickness direction orthogonal to the boundary line AA. The interval L is preferably large as long as the outer surface of the heat-resistant panel 40 is positioned inside the partition steel frame structure 10A in plan view. The interval L is, for example, 50-100 mm.
Also, in this example, the fireproof coatings 50 (partition coatings 50) are formed on the outsides of the pair of heat-resistant panels 40, respectively. Other configurations are the same as those of the first embodiment.

According to the above-described second embodiment of the present invention, the pair of heat-resistant panels 40 are fixed with the gap L therebetween. can be maintained in good health.
Therefore, it is possible to further reduce the gaps through which flames and smoke enter adjacent parking compartments in the event of a fire, as compared with the first embodiment.
Even with this configuration, the portion of the partition covering 50 that protrudes into the parking compartment from the position of the opening 11 of the steel frame 12A is none or less than the thickness of the partition covering 50 (for example, less than 30 mm), and is separated from the steel frame structure 10A. The effective area of the parking room can be increased by greatly reducing the projecting portion.

In FIG. 6, the partition fireproof wall 20 further has a heat insulating material 60 installed between the pair of heat resistant panels 40 . The heat insulating material 60 is preferably a flat plate made of a heat insulating material having light weight and heat resistance, such as rock wool, perlite, potassium silicate, or silica wool.
With this configuration, even if one of the heat-resistant panels 40 is damaged in a fire and flames or smoke enters between the pair of heat-resistant panels 40, overheating of the other heat-resistant panel 40 is prevented, making it more efficient than the first embodiment. Furthermore, it can be maintained in a healthy state.
Other effects are similar to those of the first embodiment.

As shown in FIG. 6, a metal lath 42 is fixed to the outer surface of the partition steel frame 12A, the support fitting 30, or the heat-resistant panel 40, and the outer surface is sprayed with sprayed rock wool to form the partition covering 50. You may Moreover, you may use a brace for the opening of the partition steel frame 12A as needed. The ribs are, for example, steel bars for reinforced concrete.
This configuration can reduce the required amount of sprayed rock wool and more reliably prevent the partition covering 50 from cracking or coming off.

FIG. 7 is a diagram of a third embodiment of the partition fireproof wall 20. As shown in FIG. In this figure, (A) is a plan view similar to FIG. 4 (A), and (B) is a vertical cross-sectional view taken along line FF.

In this example, the support metal fitting 30 is divided at a position where it abuts on a column (partitioning column 13A), a beam (partitioning beam 14A), or a brace (partitioning brace 15A).
7A and 7B, the support fitting 30 extends vertically inside the opening 11 with its upper and lower ends fixed to the beam (partition beam 14A) and brace (partition brace 15A). Further, the support fitting 30 is divided at a position where it abuts on the partition beam 14A and the partition brace 15A.

One horizontal surface of the support fitting 30 perpendicular to the boundary AA is positioned substantially flush with the horizontal end surface of the column (partition column 13A) or beam (partition beam 14A). there is
In FIG. 7A, one horizontal surface of the support fitting 30 is positioned substantially flush with the horizontal end surface (lower end in the figure) of the partition column 13A.

Moreover, in this example, the heat-resistant panel 40 is not divided at the brace portion and is positioned continuously.
That is, in FIGS. 7A and 7B, the heat-resistant panel 40 is not divided at the partition brace 15A, and the beams (partition beams 14A) positioned above and below are continuous without notches (openings). located.
Other configurations are the same as those of the first embodiment.

In this example, the support metal fittings 30 may extend horizontally with both ends fixed to the columns (partitioning columns 13A) and braces (partitioning braces 15A) inside the opening.
In this case, the heat-resistant panel 40 is not divided at the partition brace 15A, and is positioned continuously without notches (openings) between the columns (partition columns 13A) positioned at both ends in the horizontal direction.

According to the above-described third embodiment of the present invention, the portion of the partition coating 50 that protrudes into the parking compartment from the position of the opening 11 of the steel frame 12A is the sum of the thickness of the heat-resistant panel 40 and the thickness of the partition coating 50. It is possible to greatly reduce the protruding portion from the steel frame structure 10A and increase the effective area of the parking room.

The present invention also provides the following accompanying effects.
(1) In conventional partition fireproof walls using ALC materials, in order to cover the pillars, beams, intermediate pillars, and braces of the parking device with fireproof coating, the surface of the ALC material is covered with a curing sheet, etc. is required.
The refractory cladding of columns, beams, intermediate columns and braces is formed, for example, of sprayed rock wool. However, if the ALC material is covered with the sprayed rock wool, maintenance of the ALC material (inspection and replacement for cracks, etc.) is hindered, and the appearance is spoiled. Therefore, before the spraying step of spraying the sprayed rock wool, the ALC material curing step of covering the surface of the ALC material with a curing sheet is required, which prolongs the working process.

In contrast, in the present invention, since the partition coating 50 is continuously formed on the outer surfaces of the steel frame 12A, the support metal fittings 30, and the heat-resistant panel 40, curing such as covering the surface of the ALC material with a curing sheet is not required. It becomes one spraying process, and the work process can be shortened.

(2) A piece of ALC material is heavy (approximately 124 kg, thickness 75 mm, width 600 mm, length 4000 mm), requiring a crane or the like for lifting and mounting, resulting in poor workability at high altitudes. .
On the other hand, a single heat-resistant panel 40 according to the present invention is lightweight (for example, within 10 kg), and the work of spraying rock wool can be carried out by pumping it to a predetermined height, for example, using a pump placed on the ground floor. Moreover, since the cage 5 and the storage rack 6 can be used as a workbench, work can be performed safely and easily at a high place.

It goes without saying that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
