Description

  The present invention provides a foundation for installation of equipment for a deck foundation roof and its construction method, particularly for installing various equipment on a deck foundation roof formed by a steel deck plate (hereinafter simply referred to as “steel deck”). It is related with the foundation for the equipment installation of the deck foundation roof which is the foundation of the, and its construction method.

Conventionally, facilities such as a solar panel unit for generating electricity using natural energy (sunlight) and a hot water unit for water heating, or an outdoor unit for an air conditioner have been installed on the roof of a building. To fix it, a foundation for installation is installed on the roof.
Further, a structure for installing a roof pedestal is disclosed to solve the problem that the load on the roof surface is increased by the concrete equipment installation foundation, and to secure the waterproof performance and stably install the equipment. (For example, refer to Patent Document 1).

JP 2011-208361 A (Page 5-6, FIG. 3A)

  The invention disclosed in Patent Document 1 is called a deck plate (hereinafter referred to as a “steel deck”) having a corrugated cross section (a crest-shaped crest and a crest-shaped trough are alternately continuous in the width direction). ) And a heat insulating material installed on the top surface of the mountain portion of the steel deck, a U-shaped receiving bracket having a head and a pair of legs, and a head of the receiving bracket The raising base which is the lip channel steel mounted in the board, and the fixed rail installed in the raising base.

  The pair of leg portions are pierced from the upper surface of the cross-section material, the lower ends (tips) of the pair of leg portions are pressed against the upper surface of the mountain portion of the steel deck, and the head is substantially the same as the upper surface of the heat insulating material. It is at the same level. And the waterproof sheet which covers the head of a metal fitting and the upper surface of a heat insulating material is installed, and the metal fitting and the metal fitting in the state where the lip (the lower end of the flange) of the raising base is located on the head of the metal fitting via the waterproof sheet The raising platform is fixed to the mountain portion of the steel deck via a waterproof sheet by a tapping screw with a drill that penetrates the head of the receiving bracket and the web of the raising platform. Further, the raising base is covered with a waterproof covering material, and a fixed rail placed on the upper surface of the waterproof covering material is fixed to the fixed rail by a tapping screw with a drill through the waterproof covering material.

That is, in the invention disclosed in Patent Document 1, since a facility such as a solar panel unit is installed on the fixed rail, the load of the facility is locally applied to the peak portion of the steel deck. For this reason, there were the following problems.
(A) Since the load from the top of the equipment is concentrated on the steel deck, the legs of the catch on the steel deck's top (upper flange) are affected by the weight of the equipment, the load from the wind, earthquake, etc. There is a possibility that the pressed position and the web in the vicinity of the position (the slope portion between the upper surface of the peak portion and the lower surface of the valley portion) are locally deformed, buckled or collapsed.
(Ii) If the steel deck is crushed, the steel deck cannot support the load due to local deformation, which may lead to deformation or collapse of the roof itself. In particular, web buckling is a failure mode that must be avoided for steel.
(Iii) Furthermore, with local deformation or the like, the heat insulating material sinks or breaks, or the waterproof sheet sinks or tears, and there is a concern about deterioration of the heat insulating mechanism or the waterproof function.

(E) Furthermore, if the support is installed at a position away from the support beam supporting the steel deck (position near the center of the support span), the steel deck will be bent due to bending deformation of the steel deck. Since the compressive force parallel to the direction of the support span acts on the mountain portion, the local deformation is promoted.
(O) Therefore, at this time, it is necessary to reduce the support span (narrow the distance between the support beams) or strengthen the steel deck (thickening, improving the quality). The degree of freedom during installation decreases (installation may be difficult).

(I) The lower member is mounted on the bottom surface of the trough of the steel deck between the pair of beams (positions away from directly above the beams), and the upper member is fixed to the lower member via a heat insulating material and a waterproof sheet. Since equipment installation means for installation are provided, the load such as the weight of the equipment installed by the equipment installation means pushes down the bottom of the valley (lower flange) of the steel deck and bends the steel deck. . That is, the load on the equipment is such that the top surface (upper flange) of the steel deck is not pushed down locally.
For this reason, local deformation, buckling or crushing of the top surface (upper flange) or inclined surface (web) of the steel deck is prevented. Therefore, the possibility that the roof itself is locally deformed or collapses is eliminated.
Furthermore, the heat insulating material is prevented from sinking or cracking due to local deformation or the like, or the waterproof sheet is settling or tearing, so that the heat insulating mechanism and the waterproof function are prevented from collapsing.

(Ii) Moreover, since the front end edge of the lower leg part of the lower member has penetrated into the concave groove of the steel deck, attachment is easy, and the load of the equipment is reliably transmitted to the steel deck.
(Iii) Moreover, since the inter-member heat insulating material is installed between the upper bottom surface and the lower top surface, it is difficult for heat from the facility or the outside to be transmitted to the beam via the steel deck. Moreover, since the upper member is fixed to the lower top surface by the center fixing means via the inter-member heat insulating material, the fixing becomes easy and reliable.
(Iv) Since the lower top surface is held by the head of the member fixing bolt constituting the center fixing means and the intermediate nut, and the upper top surface portion is held by the intermediate nut and the upper nut, the fixing mechanism is simple. Fixing is easy and reliable.
(V) Moreover, since the member fixing bolt and the lower member are not in direct contact, heat transfer between them is suppressed.

(Vi) Further, since the upper member is fixed to the pair of mountain top surfaces via the heat insulating material between the members by the peripheral fixing means, the fixing becomes easy and reliable, and the rotation of the upper member with respect to the steel deck is prevented. The
(Vii) Since the surrounding fixing means is a tapping screw, the fixing mechanism is simple, and fixing is easy and reliable.

(Viii) Furthermore, since a part of the lower leg portion of the lower member is fixed to a part of the steel deck by fillet welding or screwing, the foundation for installing the equipment for the deck base roof is securely attached to the steel deck. Therefore, the reliability as the foundation for equipment installation is improved.
(Ix) Furthermore, since a relief edge is formed on the lower leg portion of the lower member, the relief edge is parallel to the ridge of the steel deck, and the bottom of the lower leg portion is pressed against the bottom of the valley. By simply rotating the member, the lower leg can be easily and reliably attached to the steel deck.

Is provided. Therefore, the load such as the weight of the equipment installed by the equipment installation means pushes down the bottom surface (lower flange) of the steel deck and bends the steel deck. That is, the load on the equipment is such that the top surface (upper flange) of the steel deck is not pushed down locally.
For this reason, local deformation, buckling or crushing of the top surface (upper flange) or inclined surface (web) of the steel deck is prevented. Therefore, the possibility that the roof itself is locally deformed or collapses is eliminated.
Furthermore, the heat insulating material is prevented from sinking or cracking due to local deformation or the like, or the waterproof sheet is settling or tearing, so that the heat insulating mechanism and the waterproof function are prevented from collapsing.

(Xi) Furthermore, as described above, local deformation, buckling or crushing of the top surface or inclined surface is prevented, and since the base column is tapered, it can be easily pierced into the roof insulation material, Since the length is substantially the same as the thickness of the roof heat insulating material, the roof heat insulating material is prevented from sinking or cracking, or the roof waterproof sheet is settling or tearing, and the heat insulating mechanism and the waterproof function are prevented from collapsing. In addition, since the base upper member and the base lower member are only connected by a thin base column (a column tip plane having a small cross-sectional area), the equipment or external heat transmitted to the upper member is made of the lower member or steel. It becomes difficult to be transmitted to the deck.
(Xii) Moreover, since the front-end edge of the lower leg part of the lower member has penetrate | invaded into the ditch | groove of the steel deck, while being easy to attach, a lower member can be reliably attached to a steel deck.

(Xiii) Further, since the center fixing means includes a member fixing bolt, an intermediate nut and an upper nut, the configuration is simple, the base lower member can be securely fixed to the lower member, and the upper member And the lower member can be reliably connected. Further, since a heat insulating material is interposed between the center fixing means and the lower member, it is difficult for heat from the facility or the outside to be transmitted to the beam via the upper member and the center fixing means.

Installation is easy, the upper member cannot be moved (rotated), and the column front end surface of the base column can be reliably pressed against the base lower member.

(Xv) Since the waterproof reinforcing sheet is installed across the upper side surface of the upper member and the roof waterproof sheet and is bonded by the bonding means, the waterproof property is improved.

In FIG. 8A to FIG. 8C, the construction method of the deck base roof equipment installation base (hereinafter sometimes referred to as “construction method”) for attaching the equipment base 200 to the deck base roof 100 is a pre-assembled facility. The foundation 200 for installation is attached to the steel deck 10, and the deck base roof 100 is completed after that.

(Assembling the foundation for equipment installation)
The assembling of the facility installation base 200 is to fix the upper member 40 to the lower member 20 via the inter-member heat insulating material 33.
That is, with the lower heat insulating material convex portion 31 c of the lower heat insulating material 31 inserted into the lower through hole 24 of the lower member 20, the lower heat insulating material surface 31 b of the lower heat insulating material 31 and the intermediate heat insulating material surface 32 b of the intermediate heat insulating material 32 To sandwich the lower top surface 22. Then, the lower washer 82 is brought into contact with the lower surface of the lower heat insulating material 31, the intermediate washer 83 is brought into contact with the upper surface of the intermediate heat insulating material 32, and the lower washer 82, the lower heat insulating material hole 31a, the intermediate heat insulating material hole 32a, and the intermediate washer 83 are formed. An intermediate nut 84 is screwed onto the penetrating member fixing bolt 81 to fix the member fixing bolt 81 to the lower member 20 (see FIG. 8B).

  Further, the member fixing bolt 81 is passed through the central through hole 33 a of the inter-member heat insulating material 33, and the upper nut 85 of the upper member 40 is screwed to the member fixing bolt 81. That is, the assembly is completed by rotating the upper member 40 until the upper bottom surface portion 44 contacts (slides) the inter-member heat insulating material 33 with respect to the lower member 20 fixing the member fixing bolt 81.

At this time, the intermediate washer 83 enters the counterbore portion 33b of the inter-member heat insulating material 33, the upper surface of the intermediate nut 84 comes into contact with the lower surface of the upper bottom surface portion 44, and the central through hole 33a of the inter-member heat insulating material 33 (FIG. 7A). (See below).

(Deck foundation roof completed)
In the deck base roof 100, the installation base 200 is attached to the valley bottom surface 14b of the steel deck 10 between the pair of beams 90 (a position away from directly above the beams 90) so that the upper member 40 is not rotated. Thereafter, the roof heat insulating material 91 and the roof waterproof sheet 92 are installed, and further, waterproof reinforcement is provided across a part of the upper member 40 exposed above the roof waterproof sheet 92 and a part of the roof waterproof sheet 92. It is completed by installing the sheet 93 (see FIG. 1).

(Installation of equipment installation foundation)
FIGS. 9A and 9B illustrate a construction method of a foundation for installing a deck foundation roof according to Embodiment 2 of the present invention. FIG. 9A shows an initial stage of attaching a lower member to the deck foundation roof. FIG. 9B is a partial plan view seen through a part explaining the end of the attachment, and FIG. 9B is a partial plan view seen through a part explained.
9A and 9B, the procedure for attaching the lower member 20 of the equipment installation base 200 to the deck base roof 100 is as follows. First, the lower relief edges 29a and 29b of the lower member 20 are the protrusions 17b and 17c of the steel deck 10. The lower leg portions 27 a and 27 b of the lower member 20 are pressed against the valley bottom surface 14 b of the steel deck 10 in a state parallel to the front end of the steel deck 10. That is, since the distance L (see FIG. 9B) between the lower clearance edge 29a and the lower clearance edge 29b is smaller than the distance H between the protrusion 17b and the protrusion 17c (L <H), the lower clearance edge 29a , 29b does not interfere with the tips of the ridges 17b, 17c.

Therefore, the lower member 20 is rotated with the normal of the valley bottom surface 14b as the center of rotation while the lower leg portions 27a, 27b are pressed against the valley bottom surface 14b of the steel deck 10. At this time, the lower surface of the inter-member heat insulating material 33 abuts (slides) on part of the top surfaces 13a and 13b.
Then, the lower tip edges 28a and 28b of the lower member 20 enter the concave grooves 18b and 18c, respectively, and the lower legs 27a and the lower legs 27b (the lower tip edge 28a and the lower tip edge are formed by the grooves 18b and 18c. (Same as 28b) and are pressed downward by the ridges 17b and 17c (more precisely, the lower surfaces of the ridges 17b and 17c forming the concave grooves 18b and 18c) ( (See FIG. 9B).
That is, at the initial rotation of the lower member 20, the intersection (corner) between the lower tip edge 28a and the lower relief edge 29a and the intersection (corner) between the lower tip edge 28b and the lower relief edge 29b are concave. The lower side faces 23a and 23b are elastically deformed by strongly abutting (sliding) on the groove 18b and the concave groove 18c, and when the rotation of the lower member 20 further proceeds, the lower tip edges 28a and 28b and the concave groove 18b, 18c becomes parallel.

At this time, the distance M (see FIG. 9A) between the lower tip edge 28a and the lower tip edge 28b is the depth of the groove 18b (the portion where the lower surface of the ridge 17b forming the groove 18b intersects the valley bottom surface 14b). And the depth G of the groove 18c (corresponding to a portion where the lower surface of the protrusion 17c forming the groove 18c and the valley bottom surface 14b intersect) is longer than M (G> G). Although the amount of elastic deformation of the lower side surfaces 23a and 23b is reduced, it is still in an elastically deformed state. Therefore, as described above, the lower end edges 28a and 28b of the lower member 20 are gripped by the grooves 18b and 18c. The
Therefore, the lower member 20 is in a state where it can reliably contact the steel deck 10 and pass force to each other by a simple operation.

  Next, a tapping screw 87 that penetrates the peripheral through hole 46 of the upper member 40 and the inter-member heat insulating material 33 is screwed (installed) on the top surfaces 13a and 13b. That is, the upper member 40 cannot be rotated with respect to the steel deck 10 (rotation with respect to the lower member 20) by the tapping screw 87 (see FIGS. 1 and 2B).

(Installation of roof insulation)
The roof heat insulating material 91 is formed with a roof heat insulating material through hole 91a through which the upper main body portion 41 of the upper member 40 passes. Accordingly, the roof heat insulating material 91 is installed on the mountain top surfaces 13a and 13b in a state where the upper bottom surface portion 44 of the equipment installation base 200 attached to the steel deck 10 so as not to rotate by the tapping screw 87 is covered (see FIG. 1). ).
In addition, as the roof heat insulating material 91, it is comprised from the roof partial heat insulating material 91b which only covers the upper bottom face part 44, and the roof whole heat insulating material 91c in which the range equivalent to the roof partial heat insulating material 91b is a space (through-hole). However, the roof partial heat insulating material 91b and the entire roof heat insulating material 91c may be integrated.
In addition, when the equipment installation foundation 200 is attached to the existing deck base roof, a through hole that covers the upper bottom surface portion 44 is formed in the existing roof heat insulating material, and the equipment installation equipment is installed via the through hole. The foundation 200 may be attached to the steel deck 10, and then a roof heat insulating material (corresponding to the roof partial heat insulating material 91b) that closes the through hole may be installed.

(Installation of roof tarpaulins)
The roof waterproof sheet 92 is formed with a sheet through hole 92a through which the upper main body portion 41 of the upper member 40 passes. Therefore, the roof waterproof sheet 92 is installed in a state of covering the roof heat insulating material 91 (the roof partial heat insulating material 91b and the entire roof heat insulating material 91c).
Further, the waterproof reinforcing sheet 93 is installed across a part of the upper member 40 above the roof waterproof sheet 92 and a part of the roof waterproof sheet 92.
The waterproof reinforcing sheet 93 includes a sheet cylindrical portion 93a that surrounds the upper main body portion 41, and a planar seat flange portion 93b that is formed continuously toward one end of the sheet cylindrical portion 93a toward the outer packet. doing. And the sheet | seat cylindrical part 93a, the upper side surface 43, the sheet | seat flange part 93b, and the roof waterproof sheet 92 are adhere | attached by the solvent-type or heat-melt-type adhesion | attachment means (refer FIG. 1).
In addition, although the adhesion means 93c and 93d are waterproof seal agents and caulking agents, the present invention is not limited to this, and a waterproof tape may be applied across both members.

  The construction method for attaching the facility installation base 200 to the deck base roof 100 is not limited to the construction method described in FIGS. 8A to 8C. First, the lower member 20 is formed into the valley bottom surfaces 14a to 14c of the steel deck 10. And then other components for installation may be attached, or after assembling a part of the installation base 200 as shown in FIG. 8B, this is applied to the valley bottom surfaces 14a to 14c of the steel deck 10. The deck foundation roof 100 may be completed by attaching and then attaching other parts of the equipment installation foundation.

(Function and effect)
The equipment installation base 200 has the above-described configuration, and the deck base roof 100 is formed by being attached to the steel deck 10 in the manner described above.
(A) The load such as the weight of the equipment installed on the upper member 40 is localized because the load transmitted to the top surfaces 13a and 13b and the bottom surface 14b of the steel deck 10 is concentrated on the top surfaces 13a and 13b. Therefore, local deformation, buckling or crushing of the top surfaces 13a, 13b or the inclined surfaces 15a, 15b, 15c, 15d is prevented. Therefore, the possibility that the deck base roof 100 is deformed or destroyed is eliminated.
(B) Further, since the sinking and cracking of the roof heat insulating material 91 or the sinking and tearing of the roof waterproof sheet 92 due to local deformation or the like is prevented, the heat insulating mechanism and the waterproof function are prevented from collapsing.

(C) Since the lower end edges 28a and 28b of the lower member 20 and the lower leg portions 27a and 27b penetrate into the concave grooves 18a and 19b of the steel deck 10, it is easy to install and The load is reliably transmitted to the steel deck 10.
(D) Since the inter-member heat insulating material 33 is installed between the upper bottom surface portion 44 and the lower top surface 22, the equipment or external heat transmitted to the upper member 40 is transmitted to the steel deck 10. It has become difficult.
(E) Since the member fixing bolt 81 passes through the lower heat insulating material hole 31a of the lower heat insulating material 31 and the intermediate heat insulating material 32a of the intermediate heat insulating material 32 and does not directly contact the lower member 20, the upper member 40 The equipment or external heat transmitted to the lower member 20 is hardly transmitted to the lower member 20.

(F) Since the upper member 40 is fixed to the lower top surface 22 by the member fixing bolt 81 and the upper nut 85 (corresponding to the center fixing means) via the inter-member heat insulating material 33, the fixing is easy and Be certain.
(G) Since the upper member 40 is fixed to the top surfaces 13a and 13b by the peripheral through-holes 46 and the tapping screws 87 (corresponding to the peripheral fixing means) via the inter-member heat insulating material 33, fixing is easy. In addition, the upper member 40 cannot rotate with respect to the steel deck 10 (lower member 20).

(H) Furthermore, since a part of the lower leg portions 27a and 27b of the lower member 20 is fixed to a part of the steel deck 10 by fillet welding or screwing, for installation of equipment on the deck base roof 100 Since the foundation 200 is securely attached to the steel deck 10, the reliability as the equipment installation foundation 200 is improved.
(I) Furthermore, since the lower relief edges 29a, 29b are formed on the lower legs 27a, 27b of the lower member 20, the lower relief edges 29a, 29b are made parallel to the protrusions 17a, 17b of the steel deck 10, The equipment installation foundation 200 can be easily and reliably attached to the steel deck 10 simply by rotating the lower member 20 with the tips of the lower legs 27a and 27b pressed against the valley bottom surface 14c.
