Description

  The present invention relates to a parking lot.

Under the current legislation, there is a possibility that the parking area of one floor is certified as certified parking lot of the planned parking lot at it if Ministry of Land, Infrastructure and Transport Minister certified on the basis of certain conditions in the 4000m ² below, it In the case of the above parking area, it becomes a parking lot building of a special building corresponding to Article 2, Paragraph 2 of the Building Standards Act, and is subject to the Building Standards Act.

  This difference is not limited to the difference in scale area, and if it is a certified parking lot, fireproof performance such as fireproof coating of pillar beams is unnecessary, fireproof compartment is unnecessary, fire extinguishing equipment is sufficient from fixed to mobile powder, Smoke exhaust equipment is not required and ventilation equipment is not required.

On the other hand, in the parking lot building that complies with the Building Standards Law, depending on the size, not have to with the fire-resistant buildings become a special building, it is necessary to carry out the fire compartment for each 1500m ^2, fire-resistant coating to the beam-to-column Or use FR steel, and fire extinguishing equipment should be fixed.

  By the way, in recent years, as supermarkets and the like have become larger, parking lots are also required to have a large capacity. For this purpose, it is not an authorized parking lot, but it is legally regulated and bulky in terms of cost, and the construction period becomes longer. The current situation is that we have to build a parking lot building.

Therefore, as a thing that can be built at a low cost while clearing the regulations as a parking lot building, for example, a fire prevention section is formed by separating a fire prevention section for every 1500 m ² and providing a space between them, Some have taken measures such as changing the fire extinguishing equipment from a fixed type to a mobile type (for example, see Patent Document 1).
JP 2001-12096 A

  Although the thing of the said Unexamined-Japanese-Patent No. 2001-12096 has provided the atrium space, if it is handled as one building, installation of the specific fire prevention equipment which forms a fire prevention division in one side of an atrium may be calculated | required, If the adjacent parking lot is treated as a separate building, there may be a portion where there is a risk of fire spread in the atrium. In such a case, it is conceivable that a fire prevention facility such as a meshed glass is provided on the opposite side of the adjacent parking lot, or that one side wall needs to be a fireproof wall.

  In addition, if the parking lot is treated as a separate building and the fire prevention equipment is to be installed, it will be necessary to place an outer wall facing the blow-off surface at a position off the area where there is a risk of fire spread. When it is 2nd floor or higher, it is necessary to secure a distance of 10 m or more between adjacent parking lots, and the space for that is also required.

  The object of the present invention is to solve the disadvantages of the conventional example, and even if the parking lot is a large-scale parking lot having a scale area or more that is certified as a certified parking lot, The object is to provide a parking lot that does not require fire walls, can reduce construction costs, and can shorten the construction period.

As the present invention achieves the above-mentioned object, the present invention according to claim 1 can obtain the Minister of Land , Infrastructure, Transport and Tourism authorization planned under a certain condition with a parking area of 1 floor of 4000 m ² or less. Use a perforated floor for the floors of the designated scale area, which is an authorized parking lot of a size that can not be regarded as a building, and provide a width to secure the prescribed spacing between adjacent parking spaces. It is connected with a work that partially connects the adjacent parking spaces, so that it is possible to secure a separation distance greater than the reference value as the adjacent building spacing between the adjacent certified parking lots, satisfying the certification condition A gist is that a space is formed , and slopes are arranged in a spiral structure in each of adjacent parking spaces adjacent to this workpiece , forming a one-way roadway between the workpiece and the slope. so That.

  According to the present invention described in claim 1, a plurality of parking spaces of a prescribed scale area that can be approved by the Ministry of Land, Infrastructure, Transport and Tourism are connected by a work that is not regarded as a building that takes a form that does not generate floor space. Therefore, each of the parking lots approved by the Minister of Land, Infrastructure, Transport and Tourism planned under certain conditions will be established independently. As a result, it is not formed as a parking lot with a specified area or more. Therefore, parking lots larger than the specified area do not need to be applied to the Building Standards Act as general parking lot buildings, so there is no need to form fire prevention zones and fire prevention equipment according to the Building Standards Act, reducing construction costs, The construction period can be shortened.

In particular, even if the parking lot has a large area as a whole, use a certified parking lot by setting the area of one floor of the connected parking lot to be a certified parking lot, currently 4000 m ² or less. Therefore, it is possible to reduce the cost by eliminating the fireproof performance of structures such as fireproof coverings such as column beams, eliminating the need for fire prevention compartments, eliminating the need for smoke and exhaust equipment, and moving fire extinguishing equipment. A formula is enough. Furthermore, it is only necessary to secure a distance between the adjacent authorized parking lots that is more than a specified distance (currently 1 m or more), and fire prevention equipment and fire walls are not required.

  Furthermore, because the slopes provided in the parking space adjacent to the workpiece and the space between the opposing slopes (adjacent equal intervals) can form a hollow spiral roadway with a double structure, these slopes are It can be used for uplink only and downlink only. Therefore, the roadway with the workpiece and the double-structured slope can be one-way, ensuring safety and reducing traffic congestion.

  In addition, by arranging the workpieces between adjacent parking spaces, it is possible to secure the prescribed adjacent building spacing between adjacent parking spaces, and even when connecting multiple certified parking lots, each connected Since the approved parking lot is established independently and does not conflict with the regulations, a large-scale parking lot can be formed as a whole.

  As described above, the parking lot according to the present invention is a large-scale parking lot by connecting a plurality of authorized parking lots with little legal restrictions with a structure that does not generate floor space because it is not regarded as a building. Therefore, it is possible to form a large-scale parking lot equivalent to a large-scale parking lot that is built as a building and has many legal regulations. Therefore, it is possible to eliminate the need for fireproof performance and fire prevention compartments, to simplify the fire extinguishing equipment, and to reduce the construction cost and the construction period.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a parking space on the first floor showing an embodiment of the parking lot of the present invention, FIG. 2 is a parking space on the second floor of the same, and the parking lot of the present invention is a three-dimensional parking lot.

The parking lot 1 of the present invention is installed adjacent to a building, and a plurality of (two in the illustrated example) parking spaces (certified parking lot 2) having a prescribed scale area that has been approved by the Minister of Land, Infrastructure, Transport and Tourism are regarded as architecture. Connected with the work piece 2 which is not done. The approved parking lot 2 certified by the Ministry of Land, Infrastructure, Transport and Tourism has a parking area of 4000 m ² or less as a specified scale area not built as a building.

  As mentioned above, this certified parking lot 2 does not require fireproof performance such as fireproof coverings of pillars and beams, does not require fire prevention compartments, fire extinguishing equipment is sufficient from fixed to mobile powder, smoke exhaustion equipment is unnecessary, ventilation equipment is unnecessary It becomes. As a result, the cost can be significantly reduced.

  For example, a perforated floor (grating, expanded metal, etc.) that is handled as a work piece is used as the work piece 3 connecting the authorized car park 2 as a building, and in the illustrated example, the adjacent authorized car park 2 The width between the adjacent buildings is a width that can secure a separation distance (currently 1 m) that is greater than the reference value. And if this adjacent building space is ensured, neither the adjacent authorized parking lot 2 is required to have a fire prevention facility or a fire wall.

  The number of authorized parking lots 2 to be connected and the number of accommodated parking lots 2 and their scale are determined by the conditions for obtaining certification. In the example shown in the figure, the authorized parking lot 2 is a double one, but is not limited to this.

  And the workpiece 3 connects between the adjacent authorized parking lots 2 in the vicinity of both ends of the opposing surface. Thereby, a separation distance (currently 1 m) that is equal to or greater than the reference value can be secured between adjacent adjacent parking lots 2 and a space 4 that satisfies the approval condition is formed.

  As shown in FIGS. 3 and 4, the slope 5 and the slope 6 are arranged in a spiral shape in the adjacent authorized parking lot 2 in contact with the space 4, and the workpiece 3, the slope 5, and the workpiece 3 are arranged. The slope 6 and the slope 6 are formed into a double structure (multilayer structure) as a spiral roadway.

  This road is formed as a one-way road because the slope 5 dedicated to the uphill and the slope 6 dedicated to the downhill are formed in a spiral shape.

  This spiral slope is applied to all parking spaces such as scale, type, and parking lot building.

  In this way, a large-scale parking lot having the same area as a parking lot building with many legal regulations can be secured by connecting a plurality of authorized parking lots 2 with little legal regulation with the workpieces 3 that are not regarded as buildings. .

  In addition, by connecting this to the slopes 5 and 6 using the connecting part of the workpiece 3, a one-way roadway exclusively for ascending and descending can be spirally formed into a multi-layer structure, so a slight space is required. The car leads can be smoothed, improving safety and reducing traffic congestion.

It is a top view of the first-floor part which shows embodiment of the parking lot of this invention. It is a top view of the second-floor part which shows embodiment of the parking lot of this invention. It is a disassembled perspective view of the roadway which shows embodiment of the parking lot of this invention. It is explanatory drawing of the roadway which shows embodiment of the parking lot of this invention.
