Then, to the hanging bolt 7 fixed to the insert or the post-installed anchor, a hanging metal object is temporarily fixed in the case of a ceiling, and a band is temporarily fixed in the case of piping, a duct, etc. The ceiling base is formed by mounting the M bar, and in the case of pipes and ducts, the pipes and ducts temporarily supported by connecting them with a band are connected, extended, and finally tightened to secure the ceiling. Suspension and support work for piping, ducts, etc. were being promoted separately.

[0003]

Therefore, in order to perform suspension work for ceilings, pipes, ducts, etc., a moving scaffold that moves on a slab is required for each work, and Each work of each construction, such as marking, insert driving, drilling, anchor driving,
For each work such as piping and suspension support, a worker involved in each work has to go up and down the moving scaffold, so that very inefficient construction is performed.
Therefore, the time and cost required for such miscellaneous work occupy a large part of the weight compared to the work for the main body such as the ceiling, piping, and ducts. And, due to the fact that each of the above work is performed separately, there is a possibility that a positional deviation occurs between the insert and the ceiling, piping, duct, etc. In this case, a new anchoring work is performed again. Since it has to be repeated, a great deal of construction work has been spent on such misalignment correction.

In view of the above circumstances, the present invention allows a ceiling slab, a pipe, a duct, etc., to be efficiently attached to a concrete slab structure using a deck plate at a time, and the positional deviation can be easily corrected. It provides a deck plate.

Between the ceiling plate 6 and the deck plate 5, a ceiling space 9 is supported, and the ceiling plate 6 is suspended and supported by suspension bolts 7 so that a predetermined gap L1 is formed between the ceiling plate 6 and the lower projecting end of the deck plate 5. A pipe material 10 which is formed and arranged so as to be held, and which is arranged in two lines on the left and right in the drawing for use in piping, ducts, etc. is mounted on the ceiling plate 9 at an upward protruding portion of the deck plate 5 in the drawing. Slab structure 1 with two hanging bolts 7 arranged side by side in the figure
It is arranged so as to be supported and fixed to. On the lower side of the ceiling board 6 in the drawing, a working space 19 is formed in such a manner that a lower floor which is formed by dividing the slab structure 1 into upper and lower floors is arranged. The mobile scaffold 20 is provided during the work.

The deck plate 5, as shown in FIG.
It has a plate body 11 formed by concavo-convex processing of a steel plate or the like, and the plate body 11 is such that concrete is placed on the concrete placing surface 11a side which is one surface shown in the upper side of the plate body 11 in the figure. In this case, it is used as a formwork of the concrete, and can be a part of the structure of the slab structure 1 as a reinforcing member of the slab structure 1 formed by hardening the concrete. In the plate 11,
A concave rib 12 in which the concrete placing surface 11a is recessed, that is, a shape in which an upward projecting portion is shown in FIG. 1, and a convex rib in which the concrete placing surface 11a is convex, that is, a shape in which a downward projecting portion is shown in FIG. 13 are formed such that the concave ribs 12 and the convex ribs 13 are alternately arranged in the left-right direction in the figure, that is, in the arrow A and B directions, and extend in the arrow C and D directions in the figure. Further, the plate body 11 is further provided with a reinforcing groove 15 in such a manner that the concrete placing surface 11a having an uneven shape by the concave ribs 12 and the convex ribs 13 is further recessed, and the reinforcing groove 15 is provided on the rising portion 11 of the plate body 11.
1, 111 are almost adjacent to each other or adhered to each other, and indicated by an arrow C,
A shape that extends in the D direction and is formed on each of the concave ribs 12 and the convex ribs 13 and that allows the plate 11 to support the ceiling plate 6, the pipe material 10 and the like via the hanging bolts 7. The supporting portions 150 of the above are provided in a shape formed in each reinforcing groove 15. That is, the support portion 150 has a plurality of widened portions 151 in the reinforcing groove 15, and the width of the reinforcing groove 15 is slightly widened at a predetermined pitch L2 (for example, L2 = 10 cm in the embodiment). It is formed and formed in a cylindrical shape (for example, in the embodiment, an expanded bottom portion φ10 mm shown on the upper side in the drawing). The suspension bolt 7 is fitted to any of the plurality of widened portions 151, and the suspension bolt 7 is anchored to the concrete frame 2 via the widened portion 151 and has a slab structure. Supported by 1. Note that, here, the shapes and arrangements of the concave ribs 12, the convex ribs 13, and the reinforcing groove 15 may be appropriately changed depending on the type of the deck plate 5, and the above-described reinforcing groove 1
Numerical values and the like indicating the shape of 5 are just arbitrary numerical values set and used in the present embodiment. Further, the shape of the widened portion 151 is not necessarily limited to the shape of the widened bottom cylinder.

The suspension bolt 7 is, for example, as shown in FIG. 3, an anchor body 1 of a tightening expansion system.
6, the anchor body 16 includes, for example, an outer sleeve 161, an inner sleeve 162 that is fitted in the outer sleeve 161 in a tapered shape, and an expansion leg portion 163 shown in the upper part of the anchor body 16 in the figure. It is composed by. A full-screw bolt 164 shown on the lower side of the anchor body 16 in the drawing is screwed into the anchor body 16, and the hanging bolt 7
Is configured such that the full-width screw bolt 164 is screwed with respect to the outer sleeve 161 in the arrow E direction in the figure, so that the expansion leg portion 163 opens in the arrow F and F ′ directions in the figure.

Since the slab structure 1 has the above-mentioned structure, when the slab structure 1 is constructed, first, the deck plate 5 is supported by the beam structure portion of the structure already constructed. The concrete placing surface 11a side is arranged and fixed with the side facing upward. Then, a small block or the like is appropriately arranged on the side end portion of the deck plate 5, and a welding wire mesh, deformed rebar or the like is appropriately arranged on the upper side of the deck plate 5, that is, on the concrete-placing surface 11a side according to the design specifications. rear,
Concrete is placed on the concrete placing surface 11a side using the deck plate 5 as a mold. Then, the concrete is hardened in such a manner that the lower surface of the concrete is molded by the concrete placing surface 11a, and the deck plate 5 serves as a reinforcing member for the concrete together with the appropriately-arranged welded wire mesh, deformed bar and the like. In this manner, the concrete skeleton 2 is formed and constructed. Then, the concrete skeleton 2 molded in this way is
Since the plurality of widening portions 151 formed in the bottomed cylindrical shape of the deck plate 5 which is the mold of No. 1 cannot be filled with concrete, the boreholes 17 are formed in the widening portions 151, that is, A plurality of bore holes 17 are formed on the lower side of the slab structure 1, that is, on the surface portion on the side of the work space 19 in the number corresponding to the widened portion 151.

In this way, when the slab structure 1 using the concrete skeleton 2, that is, the deck plate 5 as the composite structural floor slab with concrete is formed, the ceiling plate 6 and the pipe material 10 are supported by the slab structure 1. For mounting, the mounting position of the hanging bolt 7 is selectively set, that is, marked out. By the way, as described above, the slab structure 1 is
Since the boreholes 17 are formed and arranged by the number corresponding to the widened portions 151, the plurality of boreholes 17 are just arranged in a lattice when the slab structure 1 is looked up from the work space 19, that is, again. Even if precise marking is not performed, the arrangement positions of the plurality of boreholes 17 serve as a ruler. Therefore, when carrying out the marking-out work, the marking-out work can be easily carried out by simply selecting and extracting some appropriate boreholes 17 from among the plurality of boreholes 17 in accordance with the arrangement position of the hanging bolt 7. You can do it.

In this way, when the mounting position of the suspension bolt 7 is set, that is, when some appropriate boreholes 17 are selected, as shown in FIG. 3, each of the some boreholes 17 is inserted through a hand hammer or the like. The anchor body 16 is fixedly mounted by driving in the direction of arrow G in the figure. Then, the full-screw bolt 164 is screwed in the direction of the arrow E in the drawing via a ratchet tool or the like, so that the expansion leg portion 16
3 is opened in the directions of arrows F and F'in the figure. Then, the widening leg portion 163 is anchored to the concrete skeleton 2 such that the widening leg portion 163 is in close contact with the inner portion of the widening portion 151 or the widening portion 151 is expanded or penetrated. Here, the anchor body 16 does not necessarily have to be a tightening expansion type, and for example, the anchor body 16 may be used.
In addition, if a method of driving the inner cone or the anchor body is used, it is possible to omit the screw tightening work using a ratchet tool or the like, and thus it is possible to further simplify the installation work of the hanging bolt 7. .. Also, if a suspending metal for attaching the ceiling plate 6 and a band for attaching the pipe material 10 are integrally connected to the lower end side of the full-screw bolt 164 in the figure, the anchor fixing work of the hanging bolt 7 and the ceiling plate can be performed. It is possible to perform the temporary fixing work of 6 and the pipe material 10 at the same time, and it is possible to further improve the work efficiency. In this way, if some suspension bolts 7 are attached to some of the boreholes 17, looking up at the slab structure 1 from the work space 19 now, the slab structure 1 will have some of the appropriately selected arrangements. The suspension bolt 7 hangs down from the lower side surface of the deck plate 5.

When several suspension bolts 7 appropriately selected and arranged in this manner are fixedly mounted on the slab structure 1, the ceiling plate 6 and the pipe material are supported by the slab structure 1 via the suspension bolts 7. 10 is provided.

That is, first, for example, if the pipe member 10 is to be attached, it is temporarily attached to some suspension bolts 7 anchored to the bore holes 17 in the concave ribs 13 via a band (not shown) or the like. In a fixed form, each pipe material 10 such as a vinyl chloride pipe or a steel pipe, which is appropriately selected according to the application such as a duct or a pipe, is arranged, and the temporarily fixed pipe material 10 is branched and connected vertically and horizontally as appropriate. The suspension supporting work of the pipe material 10 is completed by performing the final tightening while extending the predetermined amount while performing the same process.

In order to dispose the ceiling plate 6, for example, some hanging bolts 7 anchor-fixed to the bore holes 17 in the convex ribs 13 are provided with hanging hardware (not shown) or the like. C-chan and M-bar (not shown)
A ceiling base is formed by mounting the etc. Then, after temporarily fixing the ceiling board 6 to the ceiling base, the ceiling board 6 is properly extendedly connected and finally tightened with a countersunk screw, a cosmetic screw or the like to fix the ceiling board 6 to suspend the ceiling board 6. Complete support work. Therefore, the installation work of the suspension bolts 7 for attaching the ceiling plate 6 to the slab structure 1 can be performed simultaneously with the installation work of the suspension bolts 7 for attaching the pipe material 10 to the slab structure 1. By doing so, it is possible to improve the efficiency of the work of disposing the suspension bolt 7.

As described above, when the pipe material 10 or the ceiling plate 6 is to be attached to the slab structure 1 via the hanging bolts 7, the designed arrangement position of the pipe material 10 or the ceiling plate 6,
There may be a displacement between the position and the actual position of the hanging bolt 7 of the shape set at the construction site. Therefore, in such a case, the suspended bolts 7 that are out of position are temporarily removed by simply screwing the full-screw bolts 164 to remove them from the anchor body 16, and then the suspended bolts 7 are removed.
Relocate in the correct position. At this time, even if the work such as marking out, drilling, anchoring, etc. is not carried out separately, such as when a post-installed anchor is placed, when the misalignment is noticed, the anchor body 16 is simply attached to the appropriate borehole 17. You can easily correct the misalignment because you only have to re-type.

In this way, the ceiling material, the pipes, and the ducts are hung on the slab structure 1 by correcting the positional deviation and appropriately extendingly connecting the pipe material 10 and the ceiling plate 6 while temporarily fixing and sequentially tightening them. Can be supported. Therefore,
In all of the above-described series of operations, it is not necessary to first insert the inserts or perform the drilling work in advance, and each operation, for example, positioning of the hanging bolt 7, anchor fixing, ceiling plate 6 and pipe material. It is possible to efficiently perform the piping, suspension support, and the like of 10 in a batch, that is, it is not necessary to separately perform each operation by a specialized operator. Therefore, naturally, the inefficient construction mode in which the workers involved in each work go up and down the mobile scaffolding is naturally improved, and as a result, such a ceiling board 6, piping, Duct pipe material 10
The time and expense required for miscellaneous work to suspend and support
Great savings can be made and efficient construction work can be performed, that is, construction productivity is improved.

Further, as shown in FIG. 5, the above-mentioned supporting portion 150 has a reinforcing groove 15 and an expanded bottom portion 15a with an arrow C in the figure.
The anchor body 1 may be configured so as to be continuously formed in the D direction, and since the groove width L3 of the expanded bottom portion 15a is formed larger than the groove width L4 of the groove mouth base portion, the anchor body 1
It is possible that the ceiling plate 6, the pipe material 10, etc. are supported by the slab structure 1 via the hanging bolts 7 in such a manner that the open leg parts 163 of 6 of FIG. I can. Therefore, as a result of this, the spread leg 163 is moved to
The hanging bolt 7 can be securely anchored to the concrete body 2 without penetrating into the concrete skeleton 2. In addition, since it is not necessary to form and provide a plurality of widened portions 151 by continuously forming the widened portions 15a, it is possible to reduce the weight of the plate body 11 and more than to form a plurality of widened portions 151. It is possible to fix and support the hanging bolt 7 at an arbitrary position. Also,
Since the expanded bottom portion 15a is continuously formed in the reinforcing groove 15, the anchor body 16 can be easily moved in a form of sliding inside the expanded bottom portion 15a. The position shift can be easily corrected by moving the support position. Also, the bottom expansion part 1
5a, that is, the reinforcing groove 15 does not necessarily have to have the cross-sectional shape as shown in FIG. 5, and for example, as shown in FIG.
As shown in, the enlarged bottom part may be formed to have a round cross section. Further, in the plate body 11, a plurality of widened portions 151 are simultaneously formed in the form of continuously forming the widened bottom portions 15a, and the reinforcing groove 1 is formed.
Forming 5 does not hinder anything.

In the above-mentioned embodiment, the example in which the deck plate 5 is arranged on the lower side of the slab structure 1, that is, on the lower floor side, and the concrete constituting the concrete skeleton 2 is placed is described. Plate 5 is slab structure 1
May be used in the form of being arranged on the upper side, that is, on the upper floor 3 side, or may be used in the form of being arranged in the vertical direction of a wall structure or the like. The structure in which the deck plate 5 is used is not limited to the concrete skeleton 2 having a reinforced concrete structure, and may be, for example, a reinforced concrete structure, an ALC structure, a mortar structure, or the like.

As described above, according to the present invention,
It has a plate body 11, and concrete can be placed on one surface side of the plate body 11 in such a manner that concrete can be placed.
And a concave rib 12 having a shape in which the concrete surface 11a is recessed, and a convex rib 13 in which the concrete surface 11a is convex are provided in the plate body 11. The convex ribs 13 are formed and provided in such a manner that they can be arranged alternately side by side, and the reinforcing grooves 15 are provided in the convex ribs 13 and the concave ribs 12, respectively, on the concrete placing surface 11a.
Are further formed so as to be recessed in a groove shape.
In the deck plate 5 provided with the supporting portion 150, which is provided on the other side of the concrete placing surface 11a side, for supporting the equipment such as the ceiling plate 6 and the pipe material 10 in the reinforcing groove 15, The supporting part 150 has the reinforcing groove 15
Since a plurality of widening portions 151 are provided so that the groove width of the widening portion is locally widened, the widening portion 15 selected at an arbitrary position is formed.
1 acts to support the equipment. Therefore, it is possible to easily install the fixture at an arbitrary position through a supporting member such as the hanging bolt 7 without having to insert and fix the insert prior to placing the concrete or to perform the anchoring work together with the marking and drilling work. Can be installed. Also,
Even if there is a displacement between the installation position of the ceiling, pipes, ducts, etc. and the support member that suspends and supports it, there is no need to move the scaffolding etc. and start a new drilling work, just at any position. The positional deviation can be easily corrected only by re-selecting the widened portion 151. Therefore, the ceiling, the pipes, and the ducts can be collectively and efficiently attached to the structure such as the slab structure 1, and the deck plate 5 is one of the structural parts that reinforce the structure. Since it can be regarded as a part, the ceiling, pipes, ducts, and the like are efficiently suspended and supported by the reinforced structure having a stable structure, so that productivity and reliability of the structure are significantly improved. Further, when the support portion 150 is formed in the reinforcing groove 15 with the enlarged diameter portion such as the enlarged bottom portion 15a continuously along the extension direction of the reinforcing groove 15 to form the deck plate 5, the enlarged diameter portion is formed. Can support the equipment at any position. Then, the support portion 150 can be set at any position, and the support members such as the hanging bolts 7 supported by the support portion 150 can be fixed in a manner such that they do not fall off the expanded diameter portion. Therefore, the support member can be reliably supported by the support portion 150, which increases the reliability of equipment installation. Further, since the enlarged diameter portion is continuously formed in the reinforcing groove 15, the position of the support member can be changed by sliding in the enlarged diameter portion, and the positional deviation can be easily corrected. It is possible to suspend and support the ceiling, pipes, ducts, and the like on the structure more quickly and accurately, and to efficiently complete the installation work of these facilities.
