Description

  The present invention relates to a multilayer building and a fallen object protection fence for a multilayer building, and more particularly to a high-rise building such as a high-rise apartment house in which a fallen object protection fence is installed and a fallen object protection fence installed in the high-rise building.

  In a multi-story building, in order to protect people walking on the ground, a fall object protection fence that catches an article that has been accidentally dropped from the upper floor of the building is installed on the first floor part of the building.

  In many cases, falling objects from the upper floors fall naturally with a parabolic trajectory. Therefore, the overhanging length L of the falling object protection fence installed on the floor is assumed to be H. , L = (√ (H) / 2). For this reason, the overhanging length L of the fallen object protection rod becomes longer as the height H of the building is higher. For example, in the case of a high-rise building having a height H of 100 m, the projecting length L of the fallen object protection fence suitable for the viewpoint of fallen object protection is 5 m.

  In this way, the higher the tall building, the longer the extension length of the fall object protection fence that is suitable from the viewpoint of fall object protection. It is impossible to install a fallen object protection fence with Further, if the overhanging length of the fallen object protection rod is long, the structure as a structure becomes complicated, for example, a pole for handling the nose tip (tip) of the fallen object protection rod must be provided.

  The problem to be solved by the present invention is to install a fallen object protection fence suitable from the viewpoint of fallen object protection without increasing the overhang length even in a high-rise building having a high building height.

  In the multi-layered building according to the present invention, falling object protection rods projecting outward from the building body are installed in a plurality of layers in an overlapping manner when viewed in the building height direction.

  The multi-layer building according to the present invention is preferably a multi-layer building having a balcony, and preferably, the floor portion of the balcony integrally has a portion extending outward from the handrail fence installed on the balcony, The overhanging extension provides a fallen object protection gutter.

  In the multi-layered building according to the present invention, preferably, the upper surface of the fallen object protection rod has an upward slope from the base of the fallen object protection rod to the tip of the nose.

  In the multi-layer building according to the present invention, the fallen object protection fence may be attached to an intermediate height position of a handrail fence installed on a balcony.

  A fallen object protection fence according to the present invention is a fallen object protection fence of a multi-layered building having a balcony, and a part of the balcony floor portion that projects outward from a handrail fence installed on the balcony. The overhanging extension part forms a fallen object protection gutter.

  According to the multi-layer building according to the present invention, the fallen object is disposed in a plurality of layers in an overlapping manner when viewed in the height direction of the building, so that the fallen object is the lower layer closest to the fall start floor of the fallen object. It is received by a fallen object protection fence on the floor (middle level).

  As a result, the building height, which is the basis for calculating the appropriate overhang length of the fallen object protection rod from the viewpoint of fallen object protection, is the height between the floors where the fallen object protection rods are overlapped when viewed in the building height direction. The railing becomes the height of the railing. For example, if falling object protection fences are provided on each floor, the building height, which is the basis for calculating the overhang length, will be the railing fence height. Can be shortened regardless of the overall height.

  In addition, the floor of the balcony has a part that projects outward from the handrail fence installed on the balcony, and the projecting part of the balcony forms a fallen object protection fence. There will be no increase in the number of installations for installation of fallen object protection fences. As a result, even if the fallen object protection fences are installed in multiple levels as viewed in the building height direction, the number of constructions for the entire building does not increase.

  Embodiment 1 of the multi-layered building with a fallen object protection gutter according to the present invention will be described with reference to FIGS.

  The multi-layer building 10 of the first embodiment is a 35-story high-rise apartment house, and has a balcony 11 on each upper floor (second floor to 35 floor) other than the first floor (ground floor). A handrail fence 12 is installed on the balcony 11.

  On the outer wall surface of the multi-layer building 10, fallen object protection rods 20 projecting substantially horizontally from the building main body 15 to the outside of the building are installed in a plurality of layers in an overlapping manner as viewed in the building height direction.

  In the present embodiment, the fallen object protection rod 20 is provided every third floor, that is, the third floor, the sixth floor, the ninth floor, the 12th floor, the 15th floor, the 18th floor, the 21st floor, the 24th floor, the 27th floor, the 30th floor, the 33rd floor. It is installed almost horizontally and continuously at the floor height of each floor.

  As shown in FIG. 3, the fallen object protection fence 20 on the wall surface of the building on which the balcony 11 is provided has a base end portion 21 </ b> A attached to the eaves bottom surface (ceiling surface) 13 of the balcony 11 and a fastening portion (bolt fastening) 14. A cantilevered steel frame (support member) 21 that is fixed by the eaves bottom surface 13 and extends substantially horizontally from the lower surface 13 of the eaves, and an aluminum louver material or aluminum expanded metal attached to the outwardly projecting portion 21B of the steel frame 21 And a protection member 22 for receiving a fallen object by a unit or the like.

  In this embodiment, except for the lower-floor fallen object protection rod 20 on the third floor, the other fallen object protection rods 20 are provided every three levels, and the height Ha between the levels is about 9 m. is there. When this is applied to the calculation formula of L = (√ (H) / 2), a suitable overhang length L is about 1.5 m from the viewpoint of falling object protection. Note that (H) in the calculation formula of L = (√ (H) / 2) in this case is strictly between the height of 6 m for two layers and the height of the handrail fence 12, for example, 1.6 m. The total value may be 7.6 m.

  The height from the ground surface to the fallen protection rod 20 on the third floor is equivalent to two levels, and is below the height Ha of the third layer, so the overhang length L of the fallen protection rod 20 on the third floor is also About 1.5 m is sufficient.

  Thereby, the individual overhanging length L of the fallen object protection rod 20 that is preferable from the viewpoint of fallen object protection can be shortened, and the road boundary line d approaches the building 10 and fits the entire height of the building 10 around the building 10. Even when there is not enough room to install a protective fence, it is possible to install the falling object protective fence 20 having a suitable overhang length L from the viewpoint of falling object protection. Further, since the overhanging length L of the fallen object protection rod 20 is short, it is not necessary to provide a pole or the like for handling the nose of the fallen object protection rod 20.

  Further, since the overhanging portions by the fallen object protection rods 20 are overlapped on a plurality of floors of the multi-layer building 10, this acts as a resistance of the wind flowing along the outer wall of the building 10, and it is said that the building wind is around the high-rise building. Wind is less likely to occur, and the effect of reducing wind damage from the building wind is also produced.

  Moreover, in this embodiment, the auxiliary handrail bar 18 on the side of the building main body 15 from the handrail fence 12 is provided. The auxiliary handrail bar 18 is located at almost the same height as the handrail fence 12 to prevent people from approaching the handrail fence 12 and to reduce the possibility of accidentally dropping an object from the balcony 11 to improve safety. To do.

  Embodiment 2 of the multi-layer building with a falling object protection girdle according to the present invention will be described with reference to FIGS. 4 and 5, parts corresponding to those in FIGS. 1 to 3 are denoted by the same reference numerals as those in FIGS. 1 to 3, and description thereof is omitted.

  In the multi-layer building 10 of the second embodiment, the fallen object protection rods 20 and 30 that are installed overlappingly when viewed in the building height direction are installed on each floor except the second floor portion.

  In the present embodiment, except for the fallen object protection rod 20 on the lowest floor on the third floor, other fallen object protection rods 30 are provided for each level (each floor). In this case, in the calculation formula of L = (√ (H) / 2) for calculating a suitable overhang length L from the viewpoint of falling object protection, (H) may be the height Hb of the handrail fence 12, and Hb = 1. If the length is about 6 m, the overhang length L is about 0.6 m, which is suitable from the viewpoint of falling object protection. In this embodiment, the height from the ground surface to the fallen object protection rod 20 on the third floor is equivalent to two levels, and the overhang length of the fallen object protection rod 20 is 1 as in the first embodiment. About 5m is sufficient.

  In this way, by installing the fall object protection fence 30 on each floor, the overhang length L suitable from the viewpoint of fall object protection can be significantly shortened, and the road boundary d approaches the building 10, Even if there is not enough room to install a protective fence suitable for the overall height of the building 10, it is possible to install a falling object protective fence 30 having a suitable overhang length L from the viewpoint of falling object protection.

  Since the overhang length L of the fallen object protection rod 30 is as extremely short as about 60 cm, the fallen object protection rod 30 can be reduced in weight, and the attachment strength of the fallen object protection rod 30 to the building body 15 can be reduced. Accordingly, as shown in FIG. 5, the fallen object protection rod 30 is a stainless steel louver-like member, and is a stainless steel bracket 17 fixed (bolted) to the nose tip 16 of the balcony 11. In addition, it is mounted in a horizontal cantilever type. As a result, the installation work of the falling object protection rod 30 is simplified.

  As another embodiment, as shown in FIG. 6, the floor portion of the balcony 11 is integrally extended and extended from the handrail fence 12 installed on the balcony 11 to the outside of the building. The extended part of the part forms a fallen object protection rod 40. That is, the floor portion of the balcony 11 integrally has a portion extending outward from the handrail fence 12 installed on the balcony 11, and the overhang extending portion forms a fallen object protection rod 40. Yes.

  The construction of the overhanging extension portion is performed simultaneously with the construction of the floor portion of the balcony 11 to a suitable overhanging length L from the viewpoint of falling object protection. Thereby, the fallen object protection fence 40 can be installed without using a special fitting and member, and without requiring a special installation (attachment) process, and the construction days of the multilayer building 10 can be reduced.

  Such a fallen object protection rod 40 by overhanging the balcony floor is suitable from the viewpoint of fallen object protection because the fallen object protection rod 40 is installed in a plurality of layers in the building height direction. The fact that the overhang length L is shortened, in particular, is that the fallen object protection rod 40 is installed on each floor as in the second embodiment, and the overhang length L is greatly shortened. This is also preferable.

  As shown in FIG. 7, the fall object protection rod 40 may have the collar upper surface 40 </ b> A inclined with respect to the horizontal plane so that the tip of the nose is positioned higher than the base. This inclination is an upward gradient from the base of the fallen object protection rod 40 toward the nose, and the inclination angle θ may be about 10 ° to 20 °.

  Thus, since the fallen object protection rod 40 is inclined, it is difficult for the fallen object that has fallen on the upper surface 40A of the fallen object protection rod 40 to jump outward (outside), and the fallen object falls downstairs. It becomes difficult.

  Further, as shown in FIG. 8, the stainless steel louver-like fallen object protection rod 30 or the like is not on the extension of the eaves lower surface 13 of the balcony 11 but on the outside of the intermediate height position of the handrail fence 12. It may be provided so as to overhang.

  In this embodiment, the distance between the fallen object protection rod 30 and the upper end height position of the handrail fence 12 becomes shorter, and the overhang length L of the fallen object protection rod 30 can be further shortened.

  In this case, the fallen object protection rod 30 only needs to be fixed to the intermediate height position of the handrail fence 12 by the metal fitting 31 with the base end portion 30 </ b> A and to be supported from the handrail fence 12 by the hanging tool 32. Moreover, the fallen object protection rod 30 may be attached so as to have an upward slope from the base end part (base part) 30A toward the distal end part (nose tip) 30B, and the fallen object dropped on the fallen object protection fence 30 Is difficult to jump to the outside (outdoor side).
