  The present invention relates to a self-supporting protective wall of a building for aircraft collision countermeasures, and in particular, a self-supporting protective device that can be evaluated as an integral part of the outer wall of a building during an aircraft collision analysis without affecting the seismic design of the building. On the wall.

  In recent years, as a countermeasure for aircraft collision protection of nuclear power generation facilities, it has been practiced to prevent damage and loss of function of buildings and indoor equipment by using a method of increasing the wall thickness of a building to be protected. As one of methods for protecting the building, there is a technique as described in Patent Document 1. In this patent document 1, the protection target object is housed so as to be surrounded by a protection wall, so that the protection target object in the protection target building is suitably protected from flying objects such as aircraft and vehicle collisions. It is described that the sex can be secured.

  Moreover, in patent document 2, it has the building structure constructed | assembled by the wall thickness which resists the impact by the collision of an external projectile, and the roof structure constructed above this building structure, and a building structure and a roof structure A protective structure is described in which the objects are separated from each other and have independent foundation structures.

Japanese Patent Laying-Open No. 2015-200124 JP 2011-252800 A

  As the simplest method of protecting the building, a method of increasing the wall thickness of the outer wall of the target building and strengthening it can be considered. However, if walls are added to the existing building, the weight of the building will increase, resulting in seismic impact, so it will be necessary to re-execute seismic design and study the degree of impact on equipment. If it is determined from the results that the safety of the equipment cannot be guaranteed, the building must be strengthened or replaced.

  In order to avoid these problems, it is necessary to establish a protective wall structure that can be evaluated as an integral part of the outer wall in aircraft collision analysis, without affecting the seismic design of the building, and to design and manufacture the same.

  When a protective wall is installed at a distant position as in Patent Document 1 above, the current collision analysis technology cannot consider the energy attenuation due to the collision, so it is necessary to consider stopping the collision only with the protective wall. Don't be. In that case, it is necessary to construct a very thick protective wall, and it is necessary to secure an installation space and the construction cost increases.

  Moreover, when the roof structure is provided above the building structure as in Patent Document 2, it is necessary to review the seismic design of the building structure including the influence of the roof structure, and the building structure and the roof structure Since the objects are installed independently, the aircraft collision analysis is complicated and the accuracy may be lowered.

  Accordingly, an object of the present invention is to provide a building and a protective wall for protecting the building and the interior of the building when a flying object such as an aircraft collides without affecting the seismic design of the building and performing the building collision analysis. It is an object of the present invention to provide a self-supporting protective wall that can be evaluated as an integral part of the outer wall, a design method and a manufacturing method thereof.

  In order to solve the above-described problems, the present invention provides a self-supporting protective wall that is provided outside a building and protects the building and the interior of the building when a flying object such as an aircraft collides.

  In addition, the present invention is a design method of a self-supporting protective wall that is provided outside the building and protects the building and the interior of the building when a flying object such as an aircraft collides, where the flying object collides Calculating the wall thickness of the self-supporting protective wall from the difference between the wall thickness capable of preventing damage to equipment in the building or loss of function in the building and the wall thickness of the outer wall of the building, The amount of relative displacement with the building is calculated by seismic analysis for the self-supporting protective wall having the calculated wall thickness, and the self-supporting protection is calculated by impact analysis of the flying object against the self-supporting protective wall having the calculated wall thickness. The amount of displacement of the wall is calculated, and the distance between the self-supporting protective wall and the outer wall surface of the building is wider than the relative displacement amount with the building calculated by the seismic analysis, and the self-supporting type calculated by the collision analysis The displacement of the protective wall Also narrowed position, characterized by disposing the self-supporting protective wall spaced apart from the outer wall surface of the building.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same components are denoted by the same reference numerals, and detailed description of the overlapping portions is omitted.

  With reference to FIGS. 1A to 3, the self-supporting protective wall of Example 1 and the design method thereof will be described. FIG. 1A is a cross-sectional view schematically showing a part of a self-supporting protective wall designed by using the design method of this embodiment. FIG. 1B is a plan view schematically showing a state when the self-supporting protective wall 1 and the entire protection target building 2 of FIG. 1A are viewed from above. FIG. 2 shows a state in which an earthquake load is applied to the self-supporting protective wall 1 and the protection target building 2 in FIG. 1A, and FIG. 3 illustrates a case in which an aircraft collision load is applied to the self-supporting protective wall 1 in FIG. Indicates the state.

  Although FIG. 1B shows an example in which the self-supporting protective wall 1 is provided on a part of the side surface of the protection target building 2, it may be provided on both side surfaces of the protection target building 2 depending on the surrounding conditions or the like. The case where it is provided over the entire circumference so as to surround the target building 2 is also included.

  Moreover, in this specification, it shall call a self-supporting type protective wall in the meaning of being installed independently with respect to a building (independently).

  As shown in FIG. 1B, the self-supporting protective wall 1 of the present embodiment is installed outside the outer wall with a certain distance (gap) 3 from the outer wall surface of the building 2 to be protected. The protection target building 2 is, for example, a nuclear power plant reactor building, and a reactor 4 is disposed inside the building 2.

  Here, the interval (gap) 3 between the self-supporting protective wall 1 and the protection target building 2 will be described with reference to FIG. 1A.

  First, the difference between the wall thickness A of the outer wall of the building 2 to be protected and the wall thickness B (not shown) that prevents damage to equipment in the building 2 and / or loss of function in the building 2 The wall thickness C to be added is obtained. This wall thickness C is the wall thickness of the self-supporting protective wall 1 as shown in FIG. 1A.

  Next, seismic analysis is performed on the self-supporting protective wall 1 having the wall thickness C, and a relative displacement amount (building relative displacement a) of the self-supporting protective wall 1 with respect to the protection target building 2 is calculated.

  Similarly, the collision analysis of the aircraft (flying object) is performed on the self-supporting protective wall 1 having the wall thickness C, and the displacement b of the self-supporting protective wall 1 at the time of the aircraft (flying object) collision is calculated.

  Subsequently, an interval (gap) c ′ that satisfies a <c ′ <b is obtained, and the position of the protective wall is determined. This c ′ is the distance (gap) 3 between the self-supporting protective wall 1 and the protection target building 2.

  The operation of the self-supporting protective wall 1 of this embodiment will be described with reference to FIGS.

  By configuring the self-supporting protective wall 1 of the present embodiment as described above, when an earthquake occurs (state of FIG. 2), the interval (gap) 3 between the self-supporting protective wall 1 and the building 2 to be protected. (That is, c ′ in FIG. 1A) is wider than the relative displacement amount (building relative displacement a) of the self-supporting protective wall 1 with respect to the protection target building 2, even if the self-supporting protective wall 1 is deformed by an earthquake load, There is no contact with the protection target building 2 and there is no influence on the protection target building 2. Therefore, it is not necessary to review the seismic design of the protection target building 2 when the self-supporting protection wall 1 is provided outside the protection target building 2.

  On the other hand, when a flying object such as an aircraft collides with the self-supporting protective wall 1 (the state shown in FIG. 3), the distance (gap) 3 between the self-supporting protective wall 1 and the protection target building 2 (that is, c ′ in FIG. 1A). Is smaller than the displacement b of the self-supporting protective wall 1 at the time of the aircraft (flying object) collision, the self-supporting protective wall 1 is deformed to the outer wall surface side of the protection target building 2 in response to the aircraft (flying object) collision load, It comes in close contact with the outer wall and has a thickness equivalent to the wall thickness B that prevents damage to equipment in the building 2 to be protected and / or loss of function in the building 2 to be protected. Damage to equipment and loss of functions in the building 2 can be prevented.

  In other words, in this embodiment, when the building outdoor wall is strengthened for aircraft (flying object) collision countermeasures, a self-supporting protection is provided by separating a distance satisfying the following conditions (1) and (2) from the building outdoor wall to the outside. Establish walls.

  (1) It does not hit the outer wall of the building (reactor building) due to the relative displacement during the seismic analysis.

  (2) It is integrated with the outer wall of the building (reactor building) by the displacement when the collision analysis of the aircraft (flying object) is performed.

  According to the self-supporting protective wall of this embodiment and its design method, the impact of the building on the seismic design of the building and the building's protective wall that protects the building and its interior when a flying object such as an aircraft collides with it. Thus, it is possible to construct a self-supporting protective wall that can be evaluated as an integral part of the outer wall of the building during the aircraft collision analysis.

  With reference to FIGS. 4 to 6, the self-supporting protective wall of the second embodiment will be described. FIG. 4 is a cross-sectional view schematically showing a part of the self-supporting protective wall of this embodiment. FIG. 5 shows a state where an aircraft collision load is applied to the self-supporting protective wall 1 in FIG. The present embodiment is one of specific examples of the first embodiment. FIG. 6 is a diagram showing a specific example of the structure 12 of FIG.

  As shown in FIGS. 4 and 5, the self-supporting protective wall 1 of the present embodiment has a structure 12 that is integrated with the outer wall of the protection target building 2 due to the displacement of the self-supporting protective wall 1 due to an aircraft collision. Has at the bottom.

  In this embodiment, the self-supporting protective wall 1 is installed outside the outer wall of the protection target building 2 by the design method of the first embodiment. That is, the relative displacement amount (building relative displacement) of the self-supporting protective wall 1 with respect to the protection target building 2 calculated by the seismic analysis for the self-supporting protective wall 1 is a, and the aircraft (flying object) collision analysis with respect to the self-supporting protective wall 1 is performed. Assuming that the calculated displacement of the self-supporting protective wall 1 at the time of the aircraft (flying object) collision is b, the distance (gap) c ′ between the self-supporting protective wall 1 and the building 2 to be protected satisfies the relationship a <c ′ <b. A self-supporting protective wall 1 is provided so as to satisfy. Therefore, the interval (gap) between the self-supporting protection wall 1 and the protection target building 2 in FIG. 4 is an interval 11 wider than the sum of the relative displacements of the building when the seismic analysis is performed.

  As described above, the self-supporting protective wall 1 according to the present embodiment is fixed to the lower part during normal times and during earthquakes as shown in FIG. 4, but as shown in FIG. 5, flying objects generated by aircraft, tornadoes, etc. It has a structure (interval holding means) 12 that is released from being fixed when such a fast object collides. Specifically, the structure 12 may be a stopper structure 13 that is broken by a collision of flying objects generated by an aircraft, a tornado, or the like as shown in FIG.

  With reference to FIGS. 7 to 10, a self-supporting protective wall of Example 3 will be described. FIG. 7 is a sectional view schematically showing a part of the self-supporting protective wall of the present embodiment. FIG. 8 is a plan view schematically showing a state when the self-supporting protective wall 1 and the protection target building 2 of FIG. 7 are viewed from above. FIG. 9 shows a state when an earthquake load is applied to the self-supporting protective wall 1 and the building 2 to be protected in FIG. 7, and FIG. 10 shows a case where an aircraft collision load is applied to the self-supporting protective wall 1 in FIG. Indicates the state.

  In the present embodiment, as shown in FIGS. 7 and 8, a guide rail 21 is installed on the ground (floor surface) between the self-supporting protective wall 1 and the outer wall of the protection target building 2. The roller 22 provided in the lower part of the self-supporting protective wall 1 is configured to move along. With such a structure, it is possible to protect an appropriate location of the protection target building 2 when a flying object collides with an aircraft or a tornado.

  Also, as shown in FIG. 9, by providing the roller 22, the vibration load such as an earthquake can be released, and as shown in FIG. 10, a large one-way object such as a flying object generated by an aircraft or a tornado or the like. When a load is applied, it can move and be integrated with the outer wall.

  In addition, although the example which provides both the guide rail 21 and the roller 22 was shown in the present Example, it is also possible to provide only the roller 22 in the lower part of the self-supporting protective wall 1 without installing the guide rail 21. . In this case, when the self-supporting protective wall 1 moves to the protection target building 2 side, there is a possibility that a lateral shaking may occur, but the friction with the ground (floor surface) is reduced by the roller 22, and the self-supporting protection The movement of the wall 1 toward the protection target building 2 can be made smooth.

  With reference to FIG. 11, the construction method (manufacturing method) of the self-supporting protective wall of Example 4 will be described. FIG. 11 is a cross-sectional view showing a part of the manufacturing process of the self-supporting protective wall 1.

  The present embodiment is a method of using the mold 31 when setting the interval (gap) between the self-supporting protective wall 1 and the protection target building 2 as in the first embodiment. The formwork is not expected to have strength or adhesion to the outer wall of the building 2 to be protected.

In the construction method (manufacturing method) of the present embodiment, first, the mold 31 (first mold) is set apart from the outer wall surface of the protection target building 2 with a predetermined gap (first gap). . As described in the first embodiment, the predetermined interval (first interval) is wider than the relative displacement amount with respect to the protection target building 2 calculated by the seismic analysis for the self-supporting protective wall 1, and the self-supporting protective wall 1. A mold 31 (first mold) is installed at a position that is narrower than the displacement of the self-supporting protective wall 1 calculated by the collision analysis of the aircraft (flying object). (Step 1)
Next, another mold 31 (second mold) is separated from the mold 31 (first mold) installed in the above step (step 1) with a predetermined distance (second gap). ) On the outside of the mold 31 (first mold) installed in step 1 (on the side opposite to the protection target building 2 side). This predetermined interval (second interval) is, as described in the first embodiment, damage to equipment in the protection target building 2 or loss of function in the protection target building 2 when an aircraft (flying object) collides. Is the thickness C of the self-supporting protective wall 1 obtained from the difference between the wall thickness B that can be prevented independently and the wall thickness A of the outer wall of the building 2 to be protected. (Step 2)
Subsequently, the concrete material is poured between the two molds 31 (the first mold and the second mold) installed in Step 1 and Step 2 above, and the concrete is solidified. Wall 1 is completed. (Step 3)
The above-mentioned formwork 31 is flexible enough to prevent the self-supporting protective wall 1 from being deformed to the outer wall surface of the protection target building 2 when an aircraft (flying object) collides with the self-supporting protective wall 1 ( It is preferable to use a material having elasticity. For example, a wooden frame, a polystyrene foam material, etc. are mentioned.

  The mold 31 may be removed after the self-supporting protective wall 1 is completed. In this case, a space (gap) is formed between the self-supporting protective wall 1 and the protection target building 2, and the configuration shown in FIG.

  With reference to FIG. 12A and FIG. 12B, the self-supporting protective wall of Example 5 is demonstrated. FIG. 12A is a diagram for comparison, and corresponds to FIG. 1A of the first embodiment. FIG. 12B is a cross-sectional view schematically showing a part of the self-supporting protective wall of the present embodiment.

  In the present embodiment, high-strength concrete 5 is used to reduce the wall thickness C of the self-supporting protective wall 1 in the first embodiment. As a result, the wall thickness C to be added can be reduced, the building relative displacement a when the seismic analysis is performed on the self-supporting protective wall 1, and the displacement b of the self-supporting protective wall 1 when the aircraft collision analysis is performed. Therefore, the space required for the construction of the self-supporting protective wall 1 can be reduced.

  High-strength concrete is a type of concrete, and the cement itself, which is a component of concrete, or the stone to be mixed has a high hardness, or the water / cement ratio of the material is lowered (less water, more cement And) by increasing the density, it refers to those that are stronger than general concrete.
