Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled multi-story parking garage, and more particularly to a self-propelled multi-story parking garage when a fire occurs in a parked car.
The present invention relates to a low-cost self-propelled multi-story parking lot that can safely spread and prevent egress between cars.

[0002]

2. Description of the Related Art A multi-storey parking lot has conventionally been treated as a building, and is positioned in the same row as a general building with respect to disaster prevention. Therefore, the disaster prevention of the parking lot is basically the same as that of a general building, and the area of the fire prevention compartment is 1000
It has been determined and m ^2. The outer walls, roof, and floor of the building are protected from fire or fire by using a fire-resistant structure or a non-combustible material, and the columns and beams in the fire protection compartment are required to be covered with a fire-resistant coating. Further, it is required to equip the opening of the fire protection compartment or a portion of the opening where there is a risk of spreading fire with a fire prevention shutter.

[0003] In addition, for a part where the building part is 3 m above the ground floor and less than 5 m above the second floor from the center line of the road, the boundary line of the adjacent land, or the center line of the distance between the outer walls of adjacent buildings. However, since this is treated as a part where there is a risk of spreading the fire, basically the same measures are required for the parking lot.

[0004] Regarding smoke-prevention compartments, it is required to provide a smoke-prevention wall in order to temporarily stop the flow of smoke and make it easier to evacuate according to the safety of evacuation and the height of fire danger. In addition, the arrangement of the smokeproof wall is different depending on whether the ceiling material is non-combustible or semi-combustible.

However, as for the self-propelled multi-story parking garage, the effective area has been expanded by increasing the number of floors or by using a step type or a continuous slope type, so that the parking efficiency is improved, and the spread of fire, smoke and smoke, and silence are reduced. After various improvements and improvements in safety aspects such as creation of a sense of security during use, and safety confirmation through full-scale experiments, it has been recognized that the above restrictions have been relaxed. 9 and 10 are a plan view and a partial elevation view showing the current self-propelled multi-story parking lot. The self-propelled multi-story parking garage 30 aims to make the self-propelled multi-story parking garage made of non-combustible material such as iron material to prevent fire spread and to make it non-combustible.
Expanded metal, grating metal, perforated metal, etc. used for the 2nd floor slabs and inclined road slabs are made of specially approved iron plates. It is approved that the parking area is 4.00 m ² , and the two-layer three-tier parking area is 8.000 m ² .

[0006] Regarding the prevention of fire spread to adjacent land, etc.,
Secure a distance of 0.5 m or more from the border line of the adjacent land to the outer peripheral line of the self-propelled multi-story parking lot. If the outer line of the self-propelled multi-story parking lot on the first floor is less than 1.0 m from the border of the adjacent land,
A fire protection fence 31 having a height of 2.0 m or more is provided inside the boundary line of the adjacent ground, and a portion having a height of 0.5 m or more is covered with a noncombustible material or a quasi-noncombustible material. On the second floor and the rooftop, when the outer line of the self-propelled multi-story parking lot is less than 1.0 m from the border of the adjacent land, etc., a fire protection fence 32 with a height of 1.5 m or more is provided. The part is covered with a non-combustible material or a semi-combustible material.
In order to prevent the spread of fire to the upper part, the height of the slab on the upper floor is set to 2.5 m, and the slab on the upper part of the vehicle compartment is closed. Is obliged.

[0007] Furthermore, regarding smoke control, an open space of 0.5 m or more from the adjacent land boundary is secured around the periphery of the self-propelled multi-story parking garage to secure the effectiveness of the side opening. In order to secure the evacuation safety of the floor while controlling the smoke concentration on the upper floor,
The opening ratio of the openings provided on the upper floor slab and the roof slab is 2% or more.
Limit to 20%. However, for the side opening, half of the opening length is added as an effective opening. If it is not possible to secure an open space of 0.5m or more from the border of the adjacent land around the self-propelled multi-story parking lot, a fire spread fire barrier made of semi-combustible material will be built. I have responded as.

Further, from the same viewpoint as that of a general building, in order to prevent the fire from spreading from the stricken object to the upper floor, an opening is not provided in the cabin 33 in which a car that may burn is placed. ,
It is general to provide the vehicle exclusively on the roadway 34, and the opening 35 disposed on the roadway is also provided on the upper floor or on the upper floor to increase the amount of smoke discharged while limiting the opening degree to suppress the smoke density on the upper floor. The opening was placed at the same position as the opening on the floor slab of the roof, making it open from the ground to the roof. For this reason, the rainwater falls from the opening 35 provided on the roof spreads to each level, and there is a concern about a slip accident on a wet road surface. It was also regarded as a problem in terms of gender.

[0009]

However, since conventional self-propelled multi-story parking lots are basically obliged to be regulated as buildings, improvement proposals such as safety based on the regulation are proposed. There is no history of seriously examining the pursuit of the essential function of the structure and the establishment of performance in each part.

[0010] However, in order to further increase the height of the self-propelled multi-story parking garage from three-tiered two-tiered parking garage to four-tiered three-tiered parking garage, the load on the frame structure accompanying the increase in the height is increased. It is necessary to clarify concerns about safety, etc. regarding changes in the form of fire spread in large scale and smoke flow along the lower surface caused by the slab sloping and the control and prevention of diffusion of smoke by the falling wall. is important.

[0011] The parking lot is arranged in an orderly manner while maintaining a sufficient gap in the same thing as a car, in contrast to a general building centering on equipment and household goods installed inside as a building. It is necessary to imagine an independent structure apart from corresponding in a simple frame of a building.
In particular, in order to guarantee the essential quality and performance required of parking lots, such as the thoroughness of manufacturer responsibilities and the tendency of quality assurance in response to recent social trends, large-scale parking Of fire spread in the case of fire, the spread of fire in a car near free space, the change in heat load and frame load on the frame due to the spread of heat, the smoke control effect due to the wall effect under the inclined floor, and the upper floor It is necessary to pursue and study the performance of preventing fire from spreading from the structural and essential aspects.

The present invention is proposed in view of these circumstances, and it is necessary to specify a fire-prevention compartment area and to use a fire-resistant structure or a non-combustible material for fire prevention, which is required in response to conventional general buildings. By essentially reexamining the installation of fire walls to prevent fire and spread of fire, the placement of smoke outlets, and the installation of smoke-prevention walls, the aim was to reduce manufacturing costs while improving safety and security measures. The purpose is to provide a self-propelled multi-story parking lot.

[0013]

A self-propelled multi-story parking garage according to the first and second aspects of the present invention has a structure in which fireproof equipment is provided on the outer periphery of the self-propelled multi-story parking garage or all of the structures are open.
It features a ventilation opening on the upper floor or the floor slab of the roof, and by causing the updraft through the ventilation opening positively, the flames and smoke generated from the burned car go straight along the car Dispersion of radiant heat to prevent the spread of fire to adjacent cars, and at the same time to form a smoke layer on the upper floor or roof slab, continuously outside the self-propelled multi-story parking lot It has created a propulsion force to exhaust smoke.

In the self-propelled multi-story parking lot according to the third, fourth and fifth aspects of the present invention, the ventilation opening is located on the lane of the vehicle, on the boundary of the parking lot, and on the boundary of the rear car in the rearward parking lot. It is characterized by the arrangement, and embodies the formation of a propulsion force for exhausting smoke by forming a disaster prevention air curtain and forming a smoke layer.

In the self-propelled multi-story parking lot according to the invention as set forth in claims 6, 7 and 8, when the boundary between the vehicles in the back-to-back parking section is a step, the ventilation opening is formed by the boundary between the vehicles and the step. It is characterized in that it is formed over a surface or a step surface and the rear of the parking section, and is effective when applied to a sloped or stepped self-propelled multi-story parking lot.

The self-propelled multi-story parking lot according to the ninth aspect of the present invention is characterized in that the ventilation opening is arranged at a position that does not become a communication opening with the ventilation openings arranged on the upper and lower floors or the floor slab of the roof. It is effective to prevent rainwater from falling.

The self-propelled multi-story parking garage according to the tenth, eleventh and twelfth aspects of the present invention is obtained by applying the above-described inventions to one-tier two-tier, two-tier three-tier and three-tier four-tier parking. In addition, the need for conventional general buildings to respond to the need to expand the field of view by eliminating the need to specify the area of fire protection compartments and to install fire-resistant fences using fire-resistant structures or non-combustible materials to prevent fires and spread of fire. The aim is to improve the safety and security measures of the multilevel parking garage and to reduce manufacturing costs.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION A self-propelled multi-story parking lot according to the present invention is equipped with fireproof equipment on the outer periphery of the self-propelled multi-story parking lot or has a fully open structure, and a ventilation opening is provided on an upper floor or a roof slab. A fire prevention air curtain that raises the flames and smoke generated from the burned car directly above the car by raising the rising air flow through the ventilation opening and radiating heat. To prevent the spread of fire to adjacent cars, and at the same time, to form a smoke layer on the upper floor or on the floor slab to create a propulsion force that continuously emits smoke outside the self-propelled multi-story parking lot. This is one layer 2
The present invention is applied to the parking lots of two-tier, two-tier, three-tier, and three-tier four-tier to improve safety and crime prevention measures, and at the same time reduce manufacturing costs.

Regarding the structural disaster prevention surface in the self-propelled multi-story parking lot, as described above, since the self-propelled multi-story parking lot is started from being specified as a building, the parked car actually fires. However, it has not been confirmed what kind of state the fire spreads when fire occurs. Therefore, the inventors, etc., about the self-propelled multi-story parking lot,
In order to confirm the safety of the structural disaster prevention side, a fire experiment was conducted using a full-scale experimental model 40 shown in FIG. (See Japanese Patent Application No. 10-364007)

FIG. 8A is a plan view of the experimental model, FIG. 8B is a view taken in the direction of the arrow (b) in FIG. 8A, and FIG.
It is an arrow view of (c) of (a). The fire experiments were conducted on a plurality of different types of self-propelled multi-story parking garages, such as a flat garage 41, a flat step garage 42, or a continuous inclined garage 43, for the experimental model 40 shown in FIG. To understand the risk of fire spread to the upper floor between slabs or stepped slabs, and to collect accurate and diverse data on the characteristics of livestock smoke and side smoke emission under the influence of natural wind. Is that
The following points were clarified. Combustion properties of a large parking lot with a size of about 4.000 m ² and car combustion properties in a semi-enclosed space. (Heat generation rate and continuation time under severe fire spread conditions) Car combustion properties in a state close to free space. (Properties of fire spread under the influence of natural wind without walls) Thermal load and frame load on the frame due to combustion heat under the above conditions. Smoke control effect of the leaning wall effect under the sloping floor. (Smoke flow properties of the structure) Prevention of fire spread to upper floors. (Fluidity of the hot air flow of the structure)

In an experiment for ascertaining the above, a non-combustible wall (ALC material) 44 was used to form a fuel-dominant semi-closed space in which six automobiles were burned. First, one car 45 in the center burns and spreads to the parked car with the cars on both sides behind, and further spreads from the spread car to the cars on both sides located behind. Was done. In the experiment for grasping the above, the vehicle 46 mounted on the second stage having no surrounding wall was burned, and the combustion properties of the vehicle 46 in the free space were observed. At the same time, the flow of smoke along the lower surface of the sloping three-story floor slab and the effect of the falling wall are also grasped.

FIG. 1 is a simulated diagram for explaining the state of diffusion of the flame generated from the combustion vehicle, which has been recognized in the above-mentioned demonstration experiment. In the combustion state of the flame 1 shown in FIG. 1, the combustion itself of the automobile 2 was slow, and the flame 1 rising from the combustion part of the automobile rose more directly than expected and was extinguished in a short time, resulting in fogging. . As the reason, unlike the burning of the equipment and household goods in a general building, the fire of the parked automobile 2 is considered to be caused mainly by the fact that the small fire load indicates a relatively mild combustion property. . The second factor is that the burning flame gushes out of the vehicle through the gap in the vehicle body, but gradually rises along the vehicle body due to the rising airflow and does not greatly expand in the horizontal direction and does not contact adjacent vehicles. Is done.

Therefore, the spread of fire to another adjacent car is
It is transmitted only by radiant heat, and the spread of fire spreads out gradually over a period of time without a rapid expansion state in which multiple cars burn at the same time. Unlike the burning of equipment and household goods in a general building, it is slow, and it can be said that it is a state that smokes without reaching the floor slab on the upper floor.

The flame 1 generated from the combustion vehicle 2 becomes smoke,
If the surrounding space is sufficiently open and smoke exhaust openings are provided, the rate of smoke emission and the flow rate from the open space of the self-propelled multi-story parking lot through the smoke exhaust openings become almost constant. I have. For this reason, the smoke 3 from the burned automobile 2 quickly escapes through the smoke exhaust opening, and stays in the garage because the surrounding area is open. It has been confirmed that a smoke layer is formed and smoke is discharged outside the garage at a constant speed, and that the area under the smoke layer is almost smokeless and does not hinder evacuation or movement of people.

According to the verification by the above experiment, the situation where the parked car generates a fire and burns is as follows.
It has been found that it shows a very different course from the situation of a fire in a building that has been recognized as a starting point for disaster prevention. That is, the fire of the automobile is characteristic in the following points, unlike the combustion by household goods and equipments arranged in a normal house. The fire load of cars is extremely low compared to other household goods and equipment in the residence. Because of the low fire load on cars, the outflow of flame and smoke from a car that started a fire occurs at a nearly constant rate, as does a car that has spread a fire. Flames and smoke from the car are rising directly along the body,
There is little horizontal movement and magnification. The spread of fire from a car that caused a fire to another car is propagated by radiant heat, so the spread of fire spreads not in a sudden manner in which multiple cars burn at once, but in a step-by-step manner. The smoke flowing out of the car has a high level of horizontal flow and rapidly escapes through the smoke exhaust opening. Smoke is exhausted outside. From the above, it can be said that the disaster prevention measures for the self-propelled multi-story parking lot need to be performed from a viewpoint different from the disaster prevention measures for the general building.

The self-propelled multi-story parking garage according to the present invention is constructed based on the knowledge obtained from the above-mentioned demonstration experiments. FIG.
1 is a plan view showing an entire self-propelled multi-story parking lot 10 according to the present invention. The self-propelled multi-story parking garage 10 is composed of a cabin 11 that secures a space where a car can be parked, and a lane 12 for driving the car in the cabin 11 to enter and exit the parking position. It is constructed with pillars and upper floor slabs or roofs.

The configuration of the passenger compartment is divided into a plurality of parking sections 13. Each of the parking sections 13 is divided into basic dimensions for securing a width and a depth that allow the passenger to freely get on and off between cars parked adjacent to each other, and the pillars are arranged at a depth from the exit so as not to hinder opening and closing of the door. ing. For this reason, the column spacing from the structural surface of the self-propelled multi-story parking lot 10 is also set according to this dimension. From the above situation, the self-propelled multi-story parking garage 10 differs from general buildings in the correspondence between the arrangement of the cabin and the lane with a sufficient space between adjacent vehicles, and consequently has a sufficient plane space. And a structure arranged so as to make effective use of the above knowledge is adopted as a whole.

In the illustrated self-propelled multi-story parking garage 10, a plurality of ventilation openings are arranged. The ventilation opening 14 is a back-to-back parking section 1 divided into a centrally arranged vehicle compartment.
3 are arranged on the boundary line. Further, the ventilation openings 15 are also formed on the lateral boundaries of the specified parking sections in each of the passenger compartments arranged around. Ventilation openings 14, 15
Is structurally similar to the smoke exhaust opening conventionally formed in the roadway, but its function is different.

That is, the purpose of the ventilation opening is to positively generate an upward airflow. Basically, the upward opening of the self-propelled multi-story parking lot is generated by positively generating the upward airflow passing through the ventilation opening. To create a propulsion force that pushes the air upward and exhausts it from the ventilation opening of the upper floor or roof deck to the outside of the self-propelled multi-story parking lot. In the event of a fire, the smoke flow is specified between the ventilation openings to regulate the affected area, and at the same time, to form a smoke layer with a certain width under the upper floor or under the roof slab. It continuously emits smoke outside the self-propelled multi-story parking lot, improving visibility and improving safety during evacuation.

In addition, by consciously arranging the vehicle on the boundary between the vehicles, an upward airflow around the vehicle is actively created. This forms a disaster prevention air curtain that raises the flame or smoke generated from the burned vehicle along the vehicle and raises the fire immediately, thereby dissipating radiant heat to prevent the spread of fire to an adjacent vehicle.
For this purpose, it is desirable to dispose it on all boundaries of the cabin. However, from the viewpoint of the structure and the formation of the fire spread restriction section, in the present embodiment, as shown in the figure, The ventilation opening 14 is arranged on the boundary line of the back-to-back parking section 13 divided into the compartment arranged in the vehicle, and the ventilation is provided on the boundary line between the pillars forming the central parking section of the compartment provided in the periphery. An opening 15 is provided.

FIG. 3 is an elevational view showing the self-propelled multi-story parking lot viewed from the arrows (3)-(3) in FIG. The self-propelled multi-story parking lot 10 is, as shown, a floor slab 16 of an upper floor or a roof.
Only deploys normal structural members such as beams,
Only the handrail 17 is provided on the outer periphery of the self-propelled multi-story parking lot 10. The ventilation openings 14 are located between the cars behind each other and are located at the same position on the upper and lower floors. However, as will be described later, the horizontal flow of smoke is extremely smooth in the experimental verification. The positions of the openings can be alternately shifted without deteriorating the function.

As described above, the arrangement of the ventilation openings is combined with the fact that the plane space of the vehicle room and the lane is sufficiently secured and the outer periphery of the self-propelled multi-story parking lot is actively opened. The flame from the car rises directly above the burning car and turns into smoke, which reduces the radiant heat to prevent the spread of fire to the adjacent car.Furthermore, the smoke generated in the self-propelled multi-story parking lot was In accordance with the flow properties, it will flow smoothly through the ventilation opening to the outside of the self-propelled multi-story parking lot, and the floor slab surface in the self-propelled multi-story parking lot will have a smoke-free flat space as a whole. Can be formed.

FIGS. 4 and 5 show an embodiment in which the ventilation openings are arranged on the roadway. FIG. 4 is a plan view and FIG.
FIG. 5 is a cross-sectional view of FIG. 4 taken along arrows (5)-(5). The ventilation openings 18 are arranged at a predetermined pitch on the rooftop floor 19, and the ventilation openings 21 arranged on the lower floor 20 are the ventilation openings 1.
8 and the pitch is the same, but the arrangement position is shifted by one. Therefore, rainwater that falls from the ventilation opening on the roof floor wets the lower lane, but does not reach the lower floor or the ground floor, and floods the lane on each floor as before. And the risk of slippage is eliminated. A drainage gutter 22 for collecting and draining rainwater that has fallen is attached to the ventilation opening 21 arranged on the lower floor 20 under the floor slab, but rainwater overflows on the side surface of the drainage gutter 22. The cutout opening 23 is provided so as not to protrude so as not to obstruct the airflow.

FIGS. 6 and 7 show an embodiment in which parking sections are formed behind each other in a self-propelled multi-story parking lot of an inclined type or a stepped type. In the case of an inclined type or a step type, there is a vertical step between the cars that are aligned behind. In the present invention, a ventilation opening is provided between vehicles to create an updraft. Therefore, when there is a step, a vertical opening is provided along a step surface to establish the function. FIG. 6 is an embodiment diagram in which the ventilation openings are arranged only on the step surface. FIG. 6A is a cross-sectional view, and shows a side surface 26 that structurally joins the parking sections 24 and 25 having a step up and down.
Is provided with a ventilation opening 27. The ventilation opening is shown in FIG.
As is apparent from the front view of FIG. 1, a ventilation opening 27 having a predetermined opening area is formed on the side surface 26, and an airflow coming out from under the floor slab 24 forming one parking section is formed by the floor slab. The airflow rises from behind the cars parked in the 25 parking sections to form a flameproof air curtain between the two parking sections. Therefore, according to the above verification, since the spread of fire from the combustion vehicle is propagated by the radiant heat of the flame, the flame from the combustion vehicle parked on the floor slab 24 is positively raised and turned into fumes. By reducing the number, it is possible to prevent a fire from spreading to a car parked in the parking section of the floor slab 25. The same applies to the case where the combustion vehicle is reversed.

FIG. 7 is an embodiment view in which ventilation openings are formed and arranged in the step surface and the parking space. FIG. 7A is a cross-sectional view, in which a ventilation opening 28 is provided on a side surface 26 that structurally joins the parking sections 24 and 25 having steps up and down. As is clear from the plan view of FIG.
6 and a ventilation opening 28 having a predetermined opening area over the parking sections 24 and 25, and the airflow coming out from under the floor slab partitioning the parking section 24 is parked on the floor slab 25. An updraft flows from behind the car parked in the compartment to form a flameproof air curtain between both parking compartments. FIG.
In the above-described embodiment, the ventilation opening is formed in the vertical plane and the air flow is guided in the horizontal direction.In this embodiment, however, by providing a horizontal cut in the parking section in addition to the vertical plane, Since the vertical airflow is created through the upper and lower parking sections, the thrust of the upward airflow can be further increased. Therefore, it is possible to more positively increase the flame from the combustion vehicle, enhance the fogging and the reduction of radiant heat, and reliably prevent the spread of fire to the vehicle parked in the other parking space.

As described in detail above, the self-propelled multi-story parking garage according to the present invention positively generates an updraft through the ventilation opening by arranging the ventilation opening on the upper floor or the floor slab of the roof. , The air in the self-propelled multi-story parking lot is pushed up to create a propulsion force that exhausts the air from the upper floor or roof deck to the outside of the self-propelled multi-story parking lot, and the rising airflow around the car rises just above the car Let me.

Therefore, when a fire occurs, the smoke generated in the self-propelled multi-story parking lot smoothly flows out of the self-propelled multi-story parking lot through the ventilation opening according to the flow characteristics of the demonstration experiment. As a result, the floor space in the self-propelled multi-story parking garage can form a smoke-free flat space as a whole. Furthermore, the flame of the car is raised directly above the car to form an aerosol, thereby reducing radiant heat and preventing the spread of fire to an adjacent car.

In addition, the flow of smoke is specified between the ventilation openings to regulate the affected area, and at the same time, a smoke layer having a fixed width is formed under the floor slab on the upper floor or the roof, and the self-propelled multi-story parking lot is formed. The smoke is continuously discharged out of the park, eliminating the need to define a fire spread section in a narrow area or installing a fire shutter at the opening of a passageway, etc., improving the visibility of the entire parking lot and ensuring safety. The security and security measures are improved, and manufacturing costs are reduced.

As described above, the present invention has been described in detail based on the embodiments.
Basically, self-propelled multi-story parking lots are equipped with fireproof equipment on the outer periphery or have a fully open structure, with ventilation openings arranged on the upper floor or roof slab, and ascending through the ventilation openings By actively generating airflow, a fire-prevention air curtain is formed that raises the flames and smoke generated from the burned car along the car and rises directly above it, dissipating radiant heat and preventing fire from spreading to the adjacent car. At the same time, a smoke layer is formed on the floor of the upper floor or the roof to create a propulsion force for continuously discharging smoke outside the self-propelled multi-story parking lot. It is a matter of course that the present invention is not limited at all, and various changes can be made without departing from the spirit of the invention.
