Description

  The present invention relates to a search or rescue heliport, and more particularly to a search or rescue heliport that can be easily installed on a rooftop.

  In recent years, helicopters have been widely used for the purpose of saving lives and transporting goods in the event of a disaster, and the installation of heliports for that purpose is also increasing. In particular, the usefulness of a heliport installed on the roof of a building has been recognized because it can be used without being submerged even in the event of a flood or tsunami.

  As these roof-mounted heliports, prefabricated heliports using aluminum deck materials are becoming popular instead of concrete or asphalt heliports. Patent Document 1 discloses the technical idea of such an aluminum deck material helipad. Compared to a heliport made of concrete or the like, this heliport has various advantages such as being prefabricated so that it can be easily installed on the roof of a building, and being light in weight, the structural strength of the building can be reduced.

  However, there are various legal regulations for heliport installation, and at present it is necessary to secure a landing zone with a width and length of 15m or more as an "emergency take-off and landing field" even if mitigation conditions are taken into account. It is. Small buildings do not meet these conditions, so the roof cannot be used for helicopter takeoff and landing in an emergency.

  However, under the Aviation Law, there is a special provision that excludes the application of these laws and regulations for navigation to search or rescue in the event of an accident. (Article 81-2 of the Aviation Law) Therefore, even if the landing zone space cannot be secured, providing a heliport for search or rescue will minimize damage in the event of a natural disaster or accident. It is important for that.

  However, if such a search or rescue heliport is to be provided on the roof of an existing building, the existing building itself needs to be modified to receive the load of the search or rescue heliport and helicopter. There is a problem that it is difficult to proceed with the installation simply because it may be subject to regulations such as the Building Standards Law from the standpoint of strength.

Japanese Patent Laid-Open No. 2004-162341

  The problem to be solved is that it is difficult to provide a small search or rescue heliport on the roof of an existing building.

  The present invention is a search or rescue heliport for solving the above-mentioned problems, and is placed on a roof of an existing building, above a pillar or beam of the building, and above the foundation. It is characterized by having a heliport support part fixed to the foundation and a heliport floor provided on the upper part of the heliport support part. According to this, a search or rescue heliport can be easily installed on the roof of an existing building.

  Further, the present invention is such a search or rescue heliport, characterized in that the side surface of the heliport is installed in close contact with the parapet on the rooftop portion. As a result, the area of the heliport floor can be secured, and the influence of wind during take-off and landing of the helicopter can be reduced.

  Further, the present invention is such a search or rescue heliport, characterized in that a gap on the side surface of the heliport is closed. This can prevent the search or rescue heliport from receiving a blowing load.

  Further, the present invention is such a search or rescue heliport, characterized in that the ground height of the helipad floor is substantially the same as the ground height above the parapet. According to this, the parapet does not become an obstacle to takeoff and landing of the helicopter.

Further, the present invention is such a search or rescue heliport, and is further characterized in that the heliport support and the floor or / and the parapet of the existing building are fixed with anchor bolts. According to this, it is possible to prevent the lateral displacement of the search or rescue heliport.

It is a detailed perspective view of the search or rescue heliport of one embodiment of the present invention. It is a detailed block diagram of the search or rescue heliport of one embodiment of the present invention.

  The present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view of a search or rescue heliport according to an embodiment of the present invention.

  As shown in FIG. 1, the search or rescue heliport 1 of the present invention is installed on a rooftop portion R of a relatively small existing building B such as an elementary school. Here, the heliport 1 is installed so that the pair of side surfaces are in close contact with the parapet (handrail wall having a low rooftop portion) P. Further, the ground clearance of the helipad floor 13 is substantially the same as the ground clearance of the upper surface of the parapet P. In addition, the other pair of side surfaces not in close contact with the parapet P of the heliport 1 are provided with an inclined passage 14 and a stairway 15 that are inclined from the helipad floor 13 to the rooftop portion R. This portion is configured to close the gap between the helipad floor 13 and the rooftop portion R. The material of the inclined passage 14 and the stair passage 15 is made of aluminum from the viewpoint of weight reduction.

  FIG. 2 is a detailed perspective view of the search or rescue heliport according to the embodiment of the present invention, and shows a portion excluding the inclined passage 14 and the stairway 15. The structure is composed of the helipad floor 13 formed by combining the placing base 11, the heliport support portion 12 composed of the pillar 121, the large beam 122 and the small beam 123, and the deck material 131 fixed to the placing foundation 11.

  FIG. 3 is a more detailed configuration diagram of a search or rescue heliport according to an embodiment of the present invention, which is partially enlarged and appropriately shown in cross section. Here, about the existing building B, the structure of the building is formed with the pillar 21, the beam 22, etc. Furthermore, the waterproofing which consists of the concrete layer 23 and the material for waterproofing is below the rooftop part R. A layer 24 is provided. A parapet P is formed at the end of the rooftop portion R.

  The laying base 11 is not fixed to the structural part of the existing building, and is placed on the column 21 or the beam 22 of the existing building B. The base 11 is made of a short H-shaped steel. In addition, a raw material is not limited to H-section steel, What kind of raw material may be sufficient if it has the intensity | strength which receives a load. Moreover, the outer periphery of the placing foundation 11 is hardened by the mortar 111 in order to increase the weather resistance.

  Here, the pillar 21 and the beam 22 of the existing building B are exposed and an additional foundation is fixed thereto, or the heliport support portion 12 is not fixed. It is necessary to satisfy the provisions of the Building Standards Act, etc., and the period and cost for that are large, and the waterproof layer 24 of the rooftop portion R will be broken extensively, causing troubles such as rain leaks at a later date. This is because there is a risk of causing a problem.

  However, the laying foundation 11 is fixed to the rooftop portion R of the existing building B by anchor bolts 112. This fixing is not for receiving the load of the heliport, but for preventing the search or rescue heliport 1 from slipping laterally when an earthquake or the like occurs. In the fixing with the anchor bolt, the degree of damage to the waterproof layer 24 of the roof portion R is less than that in the case of fixing to the building foundation, and there is less risk of rain leakage at a later date.

  Of course, even when using the laying foundation 11, the strength of the search or rescue heliport 1, the weight of the helicopter taking off and landing, the impact load during takeoff and landing, the blowing load due to strong winds, etc. is calculated, Needless to say, it is confirmed that the strength is sufficiently safe.

  As shown in FIG. 3, the heliport support portion 12 is placed between a pillar 121 made of H-section steel on the base 11, a large beam 122 made of H-section steel placed on the plurality of pillars 121, and the large beam 122. , And a small beam 123 made of an aluminum extruded material that forms a square shape with the large beam 122. Here, for the fixing of the placing foundation 11 and the column 121, the column 121 and the large beam 122, and the large beam 122 and the small beam 123, a well-known technique may be used as appropriate, such as bolting or welding.

  The helipad support portion 12 is installed such that a pair of vertical side surfaces of the rectangular parallelepiped shape is in close contact with the vertical side surface of the parapet P. The large beam 122 is fixed by a parapet P and an anchor bolt 124. This fixing is also for the purpose of preventing lateral deviation.

  In addition, although the material of the column 121 and the large beam 122 is H-section steel, it is not limited to this, The material and the shape can be appropriately selected in consideration of strength and weight. Similarly, the small beam 123 is an aluminum extruded material, but this is not limited to this, and the material and shape can be selected as appropriate.

  Further, a plurality of aluminum deck materials 131 are combined on the upper part of the small beam 123 and fixed to the small beam 123 with a bolt or the like to form the heliport floor 13.

  Here, the height h1 from the rooftop portion R of the upper surface of the helipad floor 13 is formed to be substantially the same as the height h2 from the rooftop portion R of the upper surface of the parapet P. This height adjustment is made according to the height of the pillar 121.

The use of a search or rescue heliport with this configuration will be described. The search or rescue heliport 1 is installed on a relatively small building such as a roof of an elementary school.
In such a building, it is difficult to secure an area according to the “Emergency Takeoff and Landing Area” provisions under the Aviation Law, but there are no other alternatives in the event of a major disaster or major accident. There are many areas where helicopters can take off and land. Therefore, in preparation for an emergency, the search or rescue heliport 1 is installed in advance.

  A helicopter will fly to the search or rescue heliport 1 in the event of an emergency, and will land and take off. In that case, since the ground height of the heliport floor 13 of the search or rescue heliport 1 is substantially the same as the ground height above the parapet P existing on the rooftop portion R, when the helicopter takes off and landing, the parapet P protrudes and becomes an obstacle. On the contrary, if the heliport floor 13 protrudes, a bad effect due to strong wind blowing at the time of take-off and landing or bad weather is assumed, but there is no fear of the occurrence. Here, the heights are assumed to be substantially the same, but this includes a difference up to about plus or minus 20 cm. That is because the adverse effects of helicopter takeoff and landing and wind blowing are negligible.

  Here, the helicopter 1 for search or rescue is installed so that the pair of side surfaces are in close contact with the parapet P, and the other pair of side surfaces not in close contact with the parapet P of the heliport 1 Since the inclined passage 14 and the stair passage 15 are provided so as to close the gap portion, the heliport 1 as a whole is not adversely affected by the blowing of strong wind.

  It should be noted that the pair of side surfaces of the search or rescue heliport 1 are set so as to be in close contact with the parapet P. However, the close contact is preferably a case where there is no gap at all, preferably 10 cm, and a maximum gap of about 20 cm. Also included are those with This is because the wind effect can be substantially ignored at this level.

  In addition, although the pair of side surfaces of the search or rescue heliport 1 is installed so as to be in close contact with the parapet P, depending on the shape of the rooftop portion R, the 3 or 4 side surfaces may be in close contact with the parapet P. Alternatively, only one side surface may be brought into close contact with the parapet P and the remaining side surface may be closed.

  Here, the inclined passage 14 and the stair passage 15 are used not only for the purpose of blocking the side surfaces but also for the passage of people to the heliport floor 13 or the passage of carts and wheelchairs.

  In addition, the side blockage is not limited to the inclined passage 14 and the stair passage 15, and may be constituted by a vertical wall surface, and if necessary, a separate staircase or the like may be provided. The material is not limited to aluminum, and any material such as metal, plastic, or wood may be used as long as it can be closed.

  Here, as for the degree of blockage, it is desirable that the wind does not pass at all. However, even if there is a gap, it may be within a range in which the influence of the wind is substantially allowable.

  Further, the search or rescue heliport 1 is fixed to the rooftop portion R and the parapet P by anchor bolts 112 and 124, but this fixing is not for receiving the load of the search or rescue heliport 1, but generating an earthquake. This is to prevent the lateral displacement of the heliport 1 such as time. Depending on the degree of close contact between the parapet P and the helipad 1 and the prediction of shaking at the time of the earthquake, the number of anchor bolts 112 and 124 may increase or decrease, and only the rooftop portion R or the parapet P may be used. . The anchor bolt 112 or 124 is preferably an adhesive anchor from the viewpoint of ease of construction. However, the anchor bolt is not limited thereto, and an anchor bolt such as a driving anchor or a tightening anchor can be appropriately selected according to the situation.

  The heliport support 12 and the heliport floor 13 of the search or rescue heliport 1 are composed of a large beam 122, a small beam 123, and an aluminum deck material 131. However, the present invention is not limited to this, and for example, a truss structure is adopted. It is also possible to apply other existing heliport structures.

  Although the present invention has been made as a search or rescue heliport, it can also be applied to a case where an off-airfield landing or emergency landing field is installed depending on the area of the installation site and the surrounding conditions.
