Many of the foundations for fixing the equipment stand installed on the flat roof are made of concrete, and in that case, there is a problem that the load on the roof surface increases.
In addition, in the case of the above-described deck base roof, it is difficult to construct a foundation for fixing the mount on the waterproof sheet. In the deck base roof, when the air conditioning equipment or the solar power generation equipment is installed on the outer heat insulating roof, the base foundation stands up from the deck base or the roof beam, so the base foundation penetrates the waterproof sheet. Therefore, there are concerns about securing waterproof performance.

  As a solution to such a problem, a roof mounting structure shown in FIG. 9 has been proposed (Patent Document 2). In this roof mount installation structure, in the above-described outer heat insulating roof, a receiver 45 covered with a waterproof sheet 44 together with the heat insulating material 43 is provided on the roof base 42, and is raised from the top of the waterproof sheet 44 onto the receiver 45. A base 46 is arranged. The raising base 46 is fixed to the roof base 42 with a screw member 52 such as a tapping screw with a drill that penetrates the waterproof sheet 44 and the receiver 45 from the upper surface. The upper surface portion of the raising base 46 and the surrounding waterproof sheet 44 is covered with a waterproof covering material 47. A fixed rail 48 having a grip attachment head 48 a extending in a rail shape is disposed on the raising base 46 from above the prevention covering material 47, and is fixed to the raising base 46 with a screw member 53. Outer and inner sealing tapes 49 and 50 are disposed on the lower surface of the fixed rail 48 and the upper surface of the raising base 46, respectively, and a screw member 53 that fixes the fixed rail 48 passes therethrough and between the through hole and the screw member 53. Is sealed. A grip 51 attached to the grip mounting head 48a of the fixed rail 48 is attached to the frame of the gantry.

  According to this configuration, the rooftop of solar power generation equipment, air conditioning equipment, etc., with less load increase on the roof surface and improved waterproofing performance in the outer heat insulation roof provided with heat insulating material and waterproof sheet on the roof base The installation base can be installed stably.

  However, in the case of this configuration, the portion covered with the waterproof sheet 44 becomes the waterproof construction line L, so that the blowing wind load acts in the direction indicated by the arrow P1 in FIG. When the fixing portion to the fixed rail 48 is broken, there is a concern that water leaks in the direction indicated by the arrow Q1 in the figure.

  An object of the present invention is to provide an outer heat insulating roof provided with a heat insulating material and a waterproof sheet on a roof base, to reduce an increase in load on the roof surface, to ensure waterproof performance, and particularly for mounting a gantry by blowing up wind or the like. Provide a roof mount installation structure that can prevent the occurrence of water leakage even when the fixed part of the fixed rail is damaged, and can stably install the mount for rooftop installations such as solar power generation equipment and air conditioning equipment That is.

The roof mount installation structure of the present invention has a head and a plurality of legs extending downward from the head in a roof in which a heat insulating material is provided on an upper surface of a roof base and the heat insulating material is covered with a waterproof sheet. A plurality of legs that pierce the heat insulating material from the upper surface and ride on the roof base, and the upper surface of the head is substantially at the same level as the upper surface of the heat insulating material and is covered with the waterproof sheet together with the heat insulating material. And a raised base fixed on the roof base by a screw member that is arranged on the receiver from above and that penetrates the waterproof sheet and the receiver from above, and the waterproof around the raised base A waterproof covering covering the raised base over the upper surface portion of the sheet, and covering the raised base from the upper surface to the side through the waterproof covering, and fixed to the side of the raised base with a screw member Break An inverted U-shaped raised base cover, a fixed rail which has a grip attachment head extending in a rail shape and is arranged on the raised base cover and fixed to the raised base cover with a screw member; And a gripping tool attached to the gripping head mounting head of the fixed rail in a gripping state.
In the above-described configuration, the screw member of the fixed rail is more than the portion fixed to the raised base by the screw member of the raised base cover with respect to a load in the lifting direction that acts on the fixed rail from the gripping tool. It is preferable that the portion fixed to the raised base cover is more easily damaged.

  According to this configuration, the receiver having a plurality of legs is provided, the legs of the receiver pierce from the upper surface of the heat insulating material and ride on the roof base, and the raised base and the raised base on the receiver Since the frame of the gantry is installed via the cover and the fixed rail, the load of the gantry is received by the roof base material almost without acting on the heat insulating material. Therefore, the gantry can be stably installed without causing the problem of the dent of the heat insulating material due to the load of the facility, even though the roof has an outer heat insulating structure in which the heat insulating material is arranged on the roof base. Since the receiving device pierces the leg portion into the heat insulating material, it is not necessary to remove a part of the heat insulating material for the installation of the receiving device, and the receiving device can be installed easily. Since the entirety of the receiver, including the head, is covered with a waterproof sheet that covers the heat insulating material, waterproofness can be ensured only by waterproofing the penetration portion of the fixing screw member, and waterproofing is easy.

  In addition, since the raised base and the raised base cover that covers the raised base are provided, and the fixed rail is provided thereon, the frame of the equipment base attached to the fixed rail is separated upward from the upper surface of the waterproof sheet serving as the roof surface. At the same time, it also moves away from the upper surface of the waterproof covering. For this reason, it can avoid that the rainwater etc. which flow on a roof surface touch the flame | frame of an installation stand.

  In particular, since the raised base is covered with a waterproof covering, a raised base cover is provided to cover the raised base from the outside of the waterproof covering, and the fixed rail is provided on the base cover. The part that covers the upper surface of the base is a waterproof construction line. Therefore, when a strong lifting load is applied from the gripper due to wind blow of the equipment stand, etc., even if the fixed load to the raised base cover of the fixed rail is broken by the lifting load, it is below the waterproof construction line. Waterproofing performance can be maintained without affecting the parts.

Even if the raised base cover is fixed to the raised base by the lifting load, the raised base is covered with the waterproof covering material, so that the waterproof performance can be maintained. Since the attachment location by the member causes a decrease in waterproof performance to some extent when broken, it is desirable not to be damaged by a blowing load or the like.
About this, the fixing part by the screw member of the raised base cover is the screw member in the horizontal direction, and the fixing part to the raising base cover of the fixed rail is the screw member in the vertical direction. The raised base cover by the screw member of the fixed rail rather than the fixed portion of the raised base cover to the raised base by the screw member with respect to the load in the lifting direction acting on the fixed rail from the gripping tool The fixed portion to the base is more likely to be damaged, and the portion for fixing the fixed rail to the raised base cover is damaged earlier than the portion for fixing the raised base cover to the raised base. There is no damage to the part where the base cover is raised and fixed to the base.

  However, for the load in the lifting direction, the fixed portion of the fixed rail to the raised base cover is more likely to be damaged than the fixed portion of the raised base cover to the raised base. It is preferable to set the strength relationship with certainty. As a result, when a large lifting load due to wind blowing acts on the gantry, the part that fixes the fixed rail to the raised base cover is more reliable than the part that fixes the raised base cover to the raised base. The portion that fixes the raised base cover to the raised base is not damaged.

  Moreover, since it is comprised with a receiver, a raising base, a raising base cover, and a fixed rail, it can be made light weight unlike a concrete frame foundation. In this way, in an outer heat insulating roof with a heat insulating material and a waterproof sheet provided on the roof base, the load on the roof surface is reduced and waterproof performance is secured, so that a stand for solar power generation equipment, air conditioning equipment, etc. Can be installed stably.

In the present invention, the raised base comprises a combination of an outer metal member having a U-shaped cross section and an inner metal member having an inverted U-shaped cross section that fits inside the outer metal member, and the inner metal member The interior space may be filled with a heat insulating material. A hard urethane foam or the like is used as the heat insulating material.
In the case of this configuration, the waterproof performance is further improved.

In this invention, a screw member for fixing the raised base cover penetrates between the outer metal member side surface portion and the inner metal member side surface portion of the raised base, and seals between the through hole and the screw member. A sealing tape may be disposed.
In the case of this configuration, the waterproof performance is further improved.

In the present invention, the raised base may be made of a single metal member having a U-shaped cross section, and the internal space of the single metal member may be filled with rigid urethane foam.
Also in this configuration, the waterproof performance is further improved.

In this invention, a screw member for fixing the raised base cover passes through an outer surface of a single metal member constituting the raised base, and a sealing tape for sealing between the through hole and the screw member is disposed. It may be a thing.
Also in this configuration, the waterproof performance is further improved.

In the present invention, the roof base is a deck plate, the receiver is disposed on the top surface of the wavy portion of the deck plate, and the grip mounting head of the fixed rail is in a ridge direction of the wavy portion of the deck plate. It may extend along.
In this configuration, because the roof is a deck base roof, even if the roof is intended for reuse at the factory, the frame can be installed in the production stage in advance, and the entire roof including the frame can be reused It is.

  In the present invention, the roof base may be an ALC plate, a reinforced concrete structure, or plywood. In other words, even if the roof is an outer heat insulating roof other than the deck base roof, it is possible to reduce the increase in load on the roof surface and secure waterproof performance, and to install a frame such as an air conditioning facility or a solar power generation facility it can.

  In this invention, the receptacle may be a downward groove-shaped steel plate bent product, each screw member may be a tapping screw with a drill, and each sealing tape may be a butyl tape. In the case of this configuration, manufacturing and field construction are further facilitated.

  In this invention, the frame of the gantry may be a frame of the equipment gantry. For example, the frame of the gantry may be a frame of an equipment gantry in which a plurality of solar cell modules are installed. In the case of the frame of the photovoltaic power generation facility, the installation of the photovoltaic power generation facility on the outer heat insulating roof can be easily performed while reducing the load load on the roof surface and ensuring the waterproof performance.

  The roof mount installation structure of the present invention has a head and a plurality of legs extending downward from the head in a roof in which a heat insulating material is provided on an upper surface of a roof base and the heat insulating material is covered with a waterproof sheet. A plurality of legs that pierce the heat insulating material from the upper surface and ride on the roof base, and the upper surface of the head is substantially at the same level as the upper surface of the heat insulating material and is covered with the waterproof sheet together with the heat insulating material. And a raised base fixed on the roof base by a screw member that is arranged on the receiver from above and that penetrates the waterproof sheet and the receiver from above, and the waterproof around the raised base A waterproof covering covering the raised base over the upper surface portion of the sheet, and covering the raised base from the upper surface to the side through the waterproof covering, and fixed to the side of the raised base with a screw member Break An inverted U-shaped raised base cover, a fixed rail which has a grip attachment head extending in a rail shape and is arranged on the raised base cover and fixed to the raised base cover with a screw member; To the roof surface of the outer heat insulating roof provided with a heat insulating material and a waterproof sheet on the roof base. It is possible to reduce the load increase and to ensure waterproofing performance, especially when the fixed part of the fixed rail for mounting the base is damaged due to wind blowing, etc. It is possible to stably install a rack for rooftop installations such as air conditioning equipment.

  An embodiment of the present invention will be described with reference to FIGS. FIG. 1A shows a plan view of a roof that employs a gantry installation structure according to one embodiment of the present invention, and FIG. 1B shows a right side view of the roof. A solar power generation facility 30 including a plurality of solar battery modules 31 is installed on the roof 1. FIG. 2 is a perspective view showing a schematic configuration of a portion of the roof 1 of FIG. 1 where one solar cell module 31 of the photovoltaic power generation facility 30 is installed. The roof 1 of this embodiment is a deck base roof in which a heat insulating material 3 is provided on the upper surface of a deck plate 2 that is a roof base, and the heat insulating material 3 is further covered with a waterproof sheet 4.

  The frame installation structure on the roof 1 is a structure for mounting the frame 32 of the installation frame of the photovoltaic power generation facility 30, and includes the support 5, the raised base 6, the waterproof covering material 7, and the raised base cover shown in FIG. 3. 23, the fixed rail 8, and the grip 11 shown in FIG. In FIG. 2, the frame 32 of the equipment stand is a frame in which a plurality of solar cell modules 31 in the solar power generation equipment 30 are installed here. In addition to the equipment stand of the photovoltaic power generation equipment 30, the equipment stand may be a stand on which equipment such as an air conditioner outdoor unit, a cubicle, an antenna, and the like are installed. Further, the frame is not limited to the frame of the equipment frame, and may be a frame of a frame of any rooftop installation such as a signboard or a handrail installed on the rooftop.

  The material of the heat insulating material 3 of the roof 1 is made of expanded polystyrene, and the material of the waterproof sheet 4 covering the heat insulating material 3 is made of a vinyl chloride sheet. In this case, when the heat insulating material 3 is directly covered with the waterproof sheet 4, the heat insulating material (expanded polystyrene) 3 is melted with time at the contact surface between the heat insulating material 3 and the waterproof sheet 4, thereby hardening the waterproof sheet (vinyl chloride) 4. This causes the problem of end up. Therefore, as shown in FIG. 3, the insulating sheet 14 is interposed between the heat insulating material 3 and the waterproof sheet 4 so that the heat insulating material 3 and the waterproof sheet 4 are not directly touched. As a material for the heat insulating material 3, foamed resin such as urethane foam, rock wool board, glass wool, or the like may be used. In this case, the insulating sheet 14 is unnecessary.

  The support 5 is a metal fitting having a head 5a and a plurality of legs 5b extending downward from the head 5a, and the plurality of legs 5b pierce the heat insulating material 3 from the upper surface thereof as a roof base. It is placed on the upper surface of the deck plate 2. That is, the support 5 is disposed on the upper surface of the wave mountain portion 2a of the deck plate 2 that is the roof base. In this arrangement state, the upper surface of the head portion 5 a of the receiving device 5 is arranged at substantially the same level as the upper surface of the heat insulating material 3. The receptacle 5 is covered with a waterproof sheet 4 together with the heat insulating material 3. Here, a downward groove-shaped steel plate bent product is used as the receiver 5. In addition to this, the receptacle 5 may be a section of C-shaped steel.

  From the top of the waterproof sheet 4, a raised base 6 is arranged on the receiver 5, and the raised base 6 is attached to the roof base by a screw member 12 that penetrates the waterproof sheet 4 and the receiver 5 from its upper surface. It is fixed to a certain deck plate 2. A tapping screw with a drill is used as the screw member 12. The raised base 6 is composed of a combination of an outer metal member 6A having a U-shaped cross section and an inner metal member 6B having an inverted U-shaped cross section that fits inside the outer metal member 6A. The internal space is filled with rigid urethane foam 24. Instead of the rigid urethane foam 24, another heat insulating material may be filled. The outer metal member 6A and the inner metal member 6B are made of, for example, a section of C-shaped steel.

  In this way, when the raised base 6 is fixed to the deck plate 2 from the upper surface by the screw member 12 that penetrates the waterproof sheet 4 and the receiver 5, the waterproof sheet 4 is used regardless of the mechanical fixing method using the fixed disk. Can be fixed to the deck plate 2 together with the heat insulating material 3. However, in places other than the arrangement part of the raising base 6, the waterproof sheet 4 is fixed to the deck plate 2 together with the heat insulating material 3 using a fixed disk 21, as shown in FIG. The fixed disk 21 is a screw having a disk-shaped head part, and a reinforcing sheet 22 is interposed between the head part and the waterproof sheet 4. Even if the fixed disk 21 is used in this way, a part of the fixing portion of the waterproof sheet 4 can be used for fixing the raised base 6 regardless of the fixed disk 21, so that the number of fixed disks 21 used can be reduced. And cost reduction is possible.

  Further, in the mechanical fixing method in which the waterproof sheet 4 is fixed using the fixed disk 21, fluttering may occur in the waterproof sheet 4 due to wind load, and the fixed disk 21 may be loosened. In a place where the fixing of the base 6 is also used for fixing the waterproof sheet 4, the screw member 12 as a fixing means penetrates the receiving member 5 and reaches the deck plate 2, so that it is possible to expect a locking effect. is there.

  The waterproof covering material 7 is a member that covers the raised base 6 and the upper surface portion of the waterproof sheet 4 around the raised base 6, and also covers the edge portion that becomes the opening of the end face of the raised base 6. The waterproof covering material 7 may be a sheet-like material or a solid accessory formed by bending a plate material. In this embodiment, a waterproof sheet is used.

  Through this waterproof covering 7, the raised base 6 is covered with a raised base cover 23 having an inverted U-shaped cross section from the upper surface to the side surface. The raised base cover 23 is made of, for example, a piece of lip groove steel. The raised base cover 23 is fixed to the side surface of the raised base 6 with a screw member 25. A tapping screw with a drill is used as the screw member 25. Sealing tape 9 is disposed between both side surfaces of the outer metal member 6A of the raised base 6 and both side surfaces of the inner metal member 6B. The sealing tape 9 seals between the screw member 25 and the through hole of the outer metal member 6A and the inner metal member 6B through which the screw member 25 for fixing the raised base cover 23 passes. The sealing tape 9 is preferably a thick resin-made elastic sheet having a thickness of about several mm, and here a butyl tape is used. The sealing tape 9 is, for example, a double-sided adhesive tape.

  The fixed rail 8 has a grip mounting head 8 a extending in a rail shape, is disposed on the raised base cover 23, and is fixed to the raised base cover 23 with a plurality of screw members 13. The raised base cover 23 is formed higher than the raised base 6, and there is a gap between the upper plate portion of the raised base cover 23 and the upper plate portion of the raised base 6, and the screw member 13. Does not reach the upper surface of the raised base 6.

  The fixed rail 8 is configured by arranging a pair of U-shaped rail divided bodies 18 and 18 having an unequal cross section in a back-to-back arrangement. Each rail division body 18, 18 is made of steel. The fixed rail 8 is disposed such that its gripping head attaching head 8a extends along the ridgeline direction of the wave mountain portion 2a of the deck plate 2 which is the roof base. Here too, a tapin screw with a drill is used as the screw member 13. Specifically, the screw member 13 is fixed to the rail divisions 18 and 18 by penetrating from the upper surface of the lower flange thereof to the web portion serving as the upper surface portion of the raised base cover 23.

  The grip 11 is a bracket that is attached to the frame 32 of the equipment frame. The grip 11 is attached to the grip mounting head 8a of the fixed rail 8 as shown in FIG. An equipment stand for the equipment is installed on the roof 1. The gripping tool 11 includes a pair of left and right gripping part split bodies 15A and 15B, and a bolt 16 that is a screw member that connects the two gripping part split bodies 15A and 15B. The bolt 16 is configured so that the two gripper segments 15A and 15B approach each other by passing through one gripper segment 15A and screwing it into the screw hole of the other grip segment 15B. Both gripper divided bodies 15A and 15B have a pair of lip-like standing pieces 15a and 15a facing each other in the arrangement direction, and the fixed rail 8 is fixed between the compatible pieces 15a and 15a by tightening with the bolt 16. The head 8a for attaching the gripping tool is sandwiched. Further, of the two gripper divided bodies 15A and 15B, the gripper 11 is attached to the gripper mounting head 8a of the fixed rail 8 on the upper surface of one gripper split body 15A. A frame fastening bolt 19 is erected at a position that is substantially the center position in the direction in which the divided bodies 15A and 15B are arranged. As shown in FIG. 7 showing a side view of the gripping tool 11, the frame fastening bolt 19 is inserted into a bolt insertion hole (not shown) of the frame 32 of the equipment frame, and the frame is formed by a nut 20 screwed into the bolt 19. By fastening 32 to the upper surface of the gripping tool 11, the frame 32 of the equipment frame is attached on the gripping tool 11.

  The grip 11 is not limited to the one shown in FIGS. 6 and 7, and has a function of sandwiching the grip mounting head 8 a of the fixed rail 8 and a function of mounting on the frame 32 of the equipment frame. As long as it is a thing, it may be of any configuration.

  According to the roof mounting structure of the above-described structure, the receiving member 5 having a plurality of leg portions 5b is provided. The frame 32 of the installation base is installed on the support 5 via the raised base 6, the raised base cover 23, and the fixed rail 8. For this reason, the load of the installation base is received by the deck plate 2 with almost no effect on the heat insulating material 3. Therefore, although it is the roof of the outer heat insulation structure which arrange | positions the heat insulating material 3 on the deck plate 2, it can install an installation stand stably, without producing the problem of the dent of the heat insulating material 3 by the load of equipment. . Since the said receiving tool 5 pierces the leg part 5b in the heat insulating material 3, the operation | work of removing a part of heat insulating material 3 for installation of the receiving tool 5 is unnecessary, and installation of the receiving tool 5 can be performed easily. . Since the receiving member 5 is entirely covered by the waterproof sheet 4 covering the heat insulating material 3 including the head 5a, the waterproofing can be ensured only by waterproofing the penetration portion of the screw member 12 for fixing. Easy.

  Further, since the raised base 6 and the raised base cover 23 covering the raised base 6 are provided, and the fixed rail 8 is provided thereon, the frame 32 of the equipment mount attached to the fixed rail 8 serves as the roof surface of the waterproof sheet 4. While leaving away from the upper surface, it is also separated upward from the upper surface of the waterproof covering 7. For this reason, it can avoid that the rain water etc. which flow on a roof surface touch the flame | frame 32 of an installation stand.

  In particular, the raised base 6 is covered with the waterproof covering 7, the raised base cover 23 that covers the raised base 6 from the outside of the waterproof covering 7 is provided, and the fixed rail 8 is provided on the base cover 23. The portion of the waterproof covering 7 that covers the top surface of the raised base 6 is the waterproof construction line L. For this reason, even if the fixed portion of the fixed rail 8 to the raised base cover 23 is broken when a strong lifting load is applied in the direction of arrow P in FIG. Waterproofing performance can be maintained without affecting the part below the construction line L.

Even if the raised portion of the raised base cover 23 fixed by the screw member 25 is damaged by the lifting load, the raised base 6 is covered with the waterproof covering material 7, so that the waterproof performance can be maintained. Since the attachment location by the screw member 25 of 23 causes a decrease in waterproof performance to some extent when it is broken, it is desirable not to be damaged by a blowing load or the like.
Since the screw member 25 of the raised base cover 23 is fixed in the horizontal direction and the fixed member 8 is fixed to the raised base cover 23 in the vertical direction, the screw member 13 is in the vertical direction. When manufactured, the load of the fixed rail 8 is higher than the portion of the raised base cover 23 fixed to the raised base 6 by the screw member 25 with respect to the load in the lifting direction acting on the fixed rail 8 from the gripper 11. The portion fixed to the raised base cover 23 by the screw member 13 is more likely to be damaged, and the portion fixing the fixed rail 8 to the raised base cover 23 attaches the raised base cover 23 to the raised base. The portion that is fixed to the base 6 is damaged before the portion that is fixed to the base 6, and the portion that fixes the raised base cover 23 to the base 6 is not damaged.
However, the fixed portion of the fixed rail 8 to the raised base cover 23 is more easily damaged than the fixed portion of the raised base cover 23 to the raised base 6 with respect to the load in the lifting direction. It is preferable to set the strength relationship with certainty. Thus, when a large lifting load due to wind blowing acts on the gantry, the portion for fixing the fixed rail 8 to the raised base cover 23 fixes the raised base cover 23 to the raised base 6. The portion is surely damaged before the portion, and the portion that fixes the raised base cover 23 to the raised base 6 is not damaged.

  Moreover, since it is comprised by the holder 5, the raising base 6, the raising base cover 23, and the fixed rail 8, it can be reduced in weight unlike the concrete structure installation base. In this way, in the outer heat insulating roof in which the heat insulating material 3 and the waterproof sheet 4 are provided on the deck plate 2, the load increase on the roof surface is reduced and the waterproof performance is secured, so that the photovoltaic power generation equipment and the air conditioning equipment Etc. can be installed stably.

  Moreover, since the fixed rail 8 has the grip attachment head 8a extending in a rail shape, the grip 11 can be attached anywhere in the length direction, and the workability of the installation work of the equipment rack is improved.

  Moreover, in this embodiment, the screw member 25 which fixes the raising base cover 23 penetrates between the side surface portion of the outer metal member 6A and the side surface portion of the inner metal member 6B constituting the raising base 6, and passes through the penetration. Since the sealing tape 9 that seals between the hole and the screw member 25 is disposed, the waterproof performance is further improved. Filling the internal space of the inner metal member 6B with the hard urethane foam 24 also contributes to an improvement in waterproof performance.

  Further, in this embodiment, since the roof 1 is a deck base roof, even when the roof 1 is intended for reuse that is manufactured in a factory, the equipment stand can be installed in the production stage in advance. Reuse of the entire roof including

  FIG. 8 shows another embodiment of the present invention. In addition, illustration of the holding tool 11 is abbreviate | omitted in the same figure. In the roof mounting structure of this roof, in the embodiment of FIGS. 1 to 7, the raised base 6 is composed of a single metal member having a U-shaped cross section, and the side surface portion and the side surface portion of the waterproof covering material 7 A sealing tape 9 is disposed between them. Other configurations and operational effects are the same as those of the embodiment of FIGS.

  Moreover, although the above embodiment demonstrated the case where the roof base | substrate of the roof 1 was the deck plate 2, it replaced with the deck plate 2, and even if it is a reinforced concrete structure used as the roof part of a building of RC structure Alternatively, a wooden plywood may be used, and the same effects as those in the embodiment of FIGS. 1 to 7 can be obtained.
