Conventionally, a hanging plate for hanging and supporting a ceiling member is attached to a deck plate constituting a dry roof and a wet roof. For example, many attachment structures and attachment methods for attaching a hanging metal fitting from the upper position (the roof side) of the deck plate have been put to practical use, and are disclosed in Patent Documents 1 and 2 below.
In Patent Document 1, as shown in FIGS. 15A and 15B, the hanging metal fitting 15 includes a hanging portion 150 having a locking portion 150 a in which a hook portion is formed at the distal end and a male screw is formed at the proximal end, and the hanging portion 150.

Japanese Utility Model Publication No. 61-27383 JP 2006-26916 A

The prior art disclosed in the above Patent Documents 1 and 2 has several problems.
First, in the hanging metal fitting 15 described in Patent Document 1, the base end of the hanging portion 150 constituting the hanging metal fitting 15 protrudes toward the upper surface side of the deck plate 153 as shown in FIG. Moreover, in the illustrated example, the hanging metal fitting 15 is attached to the convex portion (mountain portion) of the deck plate 153. Therefore, especially in a dry roof, a roof member such as a heat insulating material or a waterproof sheet is installed on the upper surface of the deck plate 153. At that time, it is difficult to install the bolt because of obstruction, and the bolt is cut. Is very troublesome.
Further, the hanging metal fitting 15 is configured to be fixed simply by contraction of the fastening portion 152 without being bolted. In other words, this is a configuration that expects only the restraining force in the vertical direction. Therefore, in the case of a dry roof, since there is no concrete placement, the restraining force against horizontal shaking and vibration is weak, and therefore it becomes unstable when large shaking occurs.

Further, in the mounting structure of the hanging metal fitting disclosed in Patent Document 2, since the hanging metal fitting 16 is struck with the cap head 161 and attached to the deck plate 163, the member of the hanging metal fitting 16 may protrude from the upper surface of the deck plate 163. There is no point. However, the fixing of the hanging metal fitting 16 is a configuration in which the deck plate 163 is sandwiched simply by hammering, so that the fixing force is poor. Therefore, when the suspension bracket 16 is attached, when the suspension bolt of the ceiling member is screwed into the cylindrical body 160 of the suspension bracket 16, a common rotation occurs. In order to prevent this co-rotation, a troublesome work of fixing the hanging metal fitting 16 by screwing or the like is necessary.
As mentioned above, although the problem of patent document 1, 2 was mentioned, in short, the effective attachment structure and attachment method of the deck plate and a suspension metal fitting in a dry-type roof are not disclosed.

Hereinafter, the present invention will be described based on illustrated embodiments.
As shown in FIGS. 1 and 5, the present invention can be suitably applied to a so-called dry roof in which concrete is not placed on the upper surface of the deck plate 2, and the hanging metal fitting 1 for hanging the ceiling member 3 is attached to the dry roof. It is an effective attachment structure and attachment method to attach from the roof side of the deck plate 2 which comprises.

First, the deck plate 2 to which the hanging bracket 1 is attached will be described.
The deck plate 2 is a so-called corrugated steel plate in which upward opening grooves and downward opening grooves 20 are alternately formed. In the present embodiment, in particular, the hanging metal fitting 1 is attached to the downward opening groove 20, and therefore, the downward opening groove is described as the convex peak portion 20, and the upward opening groove is not particularly described.
The convex peak portion 20 has a horizontal surface portion 21 at the top, and has side surface portions 22 on both sides of the horizontal surface portion 21. The horizontal surface portion 21 is provided with a V-shaped recess portion 21a projecting downward at a substantially central position, and an installation hole 21b for inserting a suspension portion 10 of a hanging metal fitting 1 to be described later is provided in each portion of the recess portion 21a. Is provided. Moreover, a pair of jaw parts 22a and 22a are provided in the aspect which protrudes in a horizontal direction with the height position and shape which are symmetrical between both side surface parts 22 and 22. FIG. The jaw portions 22a do not have to be a pair, and a plurality of pairs may be provided.
The installation hole 21b is preferably provided at a flat position eccentric to one side instead of the central position as shown in the illustrated example when the hollow surface portion 21a is provided in the horizontal plane portion 20.

Next, the hanging metal fitting 1 of the present invention will be described.
As shown in FIGS. 1 and 2, the hanging metal fitting 1 has an opening 10 a into which the suspension bolt 6 is inserted below, and has a sheath shape in which a female screw that is a screw portion 10 b is formed on the inner peripheral surface thereof. A hanging part 10 and a horizontal extension part 11 connected to the top part of the hanging part 10 and extending in a direction orthogonal to the hanging direction of the ceiling member 3, and extending downward from both ends of the horizontal extension part 11, the tip of which is The jaw portion 22a is bent inward so that it can be held, and the holding portion 12 is provided with a stepped portion 12a.
The suspending portion 10 has a U-shaped longitudinal section that can be connected to the suspension bolt 6 of the ceiling member 3 and stored in the sheath. Therefore, even if the suspension bolt 6 is inserted from the opening 10a and screwed in, the suspension bolt 10 is accommodated in the suspension 10 and does not protrude upward.
Moreover, the suspension part 10 is not limited to a sheath shape, and can also be implemented in the same manner as a rod shape in which a male screw is formed as a screw part 10b on the outer peripheral surface thereof.

As shown in FIGS. 2A and 2B, the horizontal extension portion 11 extends horizontally from the center of the top of the suspension portion 10 like a bamboo wing, and is hooked with respect to the length direction of the convex peak portion when attached. As shown in FIG. That is, the angle is set so as to be on the ray Q passing through the center of the hanging part 10. Incidentally, the angle and the total length of the horizontal extension portion 11 are designed to be longer than the width of the horizontal plane portion 21 when placed on the horizontal plane portion 21 of the deck plate 2.
Further, the both holding portions 12 and 12 are inclined in a letter C in accordance with the inclination of both side surface portions 22 and 22 constituting the convex peak portion 20, and the step portion 12 a is also a jaw of the side surface portion 22. The height and shape can hold the portion 22a. The logarithm of the stepped portion 12a is increased or decreased according to the situation together with the logarithm of the jaw portion 22a. In the illustrated example, the holding portion 12 can be held in a curved shape having a stepped portion 12a whose tip is bent inward so that the jaw portion 22a can be held. Any shape that can hold the jaw portion 22a can be carried out without the stepped portion 12a.

The suspension bracket 1 and the deck plate 2 having the above-described configuration are configured such that the suspension portion 10 of the suspension bracket 1 is inserted from the roof side into the installation hole 21b of the projection peak portion 20 of the deck plate 2 and protrudes downward from the projection peak portion 20. The horizontal extension portion 11 of the hanging bracket 1 is horizontally rotated around the suspension portion 10, and the pair of step portions 12 a, 12 a of the holding portions 12, 12 are fitted to the pair of jaw portions 22 a, 22 a of the convex peak portion 20. It is structured to be attached together.
After that, as shown in FIG. 5, the roof member such as the heat insulating material 4 and the waterproof sheet 5 is installed, and the suspension bolt 6 of the ceiling member 3 is inserted into the opening 10 a of the suspension portion 10 of the suspension bracket 1. Build a dry roof.
Therefore, in the mounting structure of the present invention, since the roof side surface after mounting the hanging bracket 1 is a flat upper surface with no protrusion of the suspension bolt 6 of the ceiling member 3 and no protrusion of the hanging bracket 1 as shown in the figure, the heat insulating material 4 In addition, the installation work of the waterproof sheet 5 can be performed efficiently, and since the holding member 12 can be fitted to the jaw part 22a by simply rotating the suspension fitting 1 horizontally, the attachment is very simple.

Next, an attachment method for attaching the hanging bracket 1 to the deck plate 2 will be described in detail with reference to FIGS.
First, as shown in FIG. 4A, the hanging metal fitting 1 is inserted into the installation hole 21 b of the ridge 20 from the roof side of the deck plate 1. Specifically, as shown in the upper side of FIG. 3, the horizontal extension portion 11 of the hanging metal fitting 1 is inserted so as to be substantially horizontal with respect to the width direction of the convex peak portion 20, and the lower surface thereof is the convex peak portion 20. It is mounted on the upper surface of the horizontal surface portion 21. That is, since the overall length of the horizontal extension portion 11 is longer than the width of the horizontal surface portion 21 of the convex ridge portion 20 as described above, the horizontal extension portion 11 can be easily inserted and placed if it is at a horizontal angle with respect to the width direction of the convex ridge portion 20. . At the same time, the alignment of the stepped portion 12a of the holding portion 12 of the hanging bracket 1 and the jaw portion 22a of the convex peak portion 20 is performed. This is because the height position of the stepped portion a of the hanging metal fitting 1 is formed so as to coincide with the height position of the jaw portion 22a as described above.
In this state, as shown in the lower side of FIG. 3 and FIG. 4B, the horizontal extension portion 11 is horizontally rotated rightward about the suspension portion 10, and the step portions 12 a and 12 a of the holding portion 12 are The jaw portions 22a and 22a of the convex peak portion 20 are tightly fitted (see FIG. 4C). Thereafter, the roofing material (the heat insulating material 4 and the waterproof sheet 5) is installed, and the suspension bolt 6 is screwed into the suspension part 10 of the suspension bracket 1 to assemble the ceiling member 3.
In short, the hanging metal fitting 1 is inserted at an angle that allows the maximum length of the metal fitting 1 to be mounted, and it is very easy to attach both of them just by horizontally turning rightward at the fitting position of the stepped portion 12a and the jaw portion 22a. It is.

The present invention is not limited to the above-described embodiment, and can be implemented in the second embodiment shown in FIGS. 6 to 8 based on the same technical idea. Therefore, the following description will focus on differences from the first embodiment.
The deck plate 2 is the same as that of the first embodiment. To put it simply, the hanging metal fitting 7 used in the second embodiment is that the horizontal extending portion 71 is provided with elastic means for exerting elastic force. That is, the horizontal extension portion 71 is formed of four arm members that exert elastic force arranged in an X shape in plan view. Specifically, as shown in FIGS. 7A to 7C, four arm members 71 b, and two plates that support the arm member 71 b, which extend in the direction orthogonal to the hanging direction at the top of the hanging portion 70. 71a and 71a.
The plate 71a has a substantially circular core and is provided with two extension portions 71c and 71c that support two arm members 71b and 71b on a diagonal line. The two plates 71a having the above-described configuration are alternately overlapped and pin-joined, are pivotally connected at the center position, and a total of four arm members 71b are joined so as to have an X-shaped arrangement in plan view. It is configured. The angles and total lengths of the four arm members 71b arranged in the X shape, as shown on the lower side of FIG. 8, are the exact lengths without play when attached to the ridges 20 of the deck plate 2. Designed to. It should be noted that the present invention is not limited to the example shown in the figure, and it is naturally possible to carry out with only four arm members that do not use a plate. It is also possible.
Further, a spring material 71d that exhibits an elastic force is provided between the extension portions 71c of the two plate materials 71a and 71a facing each other. In FIG. 7, it is provided between the extension portions 71c facing each other on the right side, but it may be provided on the left and right. The spring material 71d maintains the distance of the extension portion 71c, and an elastic force works when the distance of the extension portion 71c is shortened, thereby contributing to immediately returning to the X-shaped position.

  The suspension bracket 7 having the above-described configuration is configured such that the suspension portion 70 is inserted into the installation hole 21b of the convex ridge portion 20 of the deck plate 2 from the roof side (upper position), and the extension portions 71c of the two plate members 71a and 71a, The distance between the two arm members 71b and 71b extending from 71c is reduced by the elastic force of the spring member 71d, and the stepped portion 72a of the holding portion 72 is disposed on the jaw portion 22a of the convex peak portion 20, and the two arms again A very simple mounting structure is realized in which the distance between the members 71b and 71b is returned to the deck plate 2 by the elastic force of the spring member 71d.

  As shown in the upper side of FIG. 8, the hanging bracket 7 is attached by inserting the hanging portion 70 of the hanging bracket 7 into the installation hole 21b of the deck plate 2 from the roof side and, for example, two arm members on the right side. When force is applied so that 71b and 71b are moved inward, the two plates 4a are rotated at the pin joint portion, and between the extension portions 71c and 71c facing each other of the two plate materials 71a and 71a. The arranged spring material 71d shrinks, the distance between the extension portions 71c and 71c shrinks, and the right arm materials 71b and 71b become substantially parallel. At this time, the right arm members 71b and 71b can obtain the longest length in the width direction of the ridge 20. When the force applied to the arm members 71b and 71b is weakened with the stepped portion 72a of the holding portion 72 of the suspension member 7 aligned with the jaw portion 22a of the convex peak portion 20, the elasticity of the spring member 71d is reduced. The distance between the extended portions where the two plate members 4a and 4a are rotated to face each other by the force returns to the initial position (X shape), and the pair of stepped portions 72a of the holding portion 72 of the suspension member 7 and the convex peak It fits tightly with the 20 pairs of jaws 22a. The effective width of the horizontal extension portion 71 is exactly the same as the width of the convex peak portion 20 and the repulsive force of the spring material 71d can be expected. Lifting can be surely prevented. Incidentally, after this, the roofing material (the heat insulating material 4 and the waterproof sheet 5) is installed, and the suspension bolt 6 is screwed into the suspension part 70 of the suspension bracket 7 as described above.

The hanging bracket 7 shown in the second embodiment can be implemented based on the same technical idea in the deck plate shown in FIGS.
That is, even a deck plate 2 ′ having a narrow, low and high convex peak portion 20 ′ can be implemented.
The difference between the suspension fitting 7 'shown in the third embodiment and the suspension fitting 7 of the second embodiment is only that the arm member 71b' constituting the horizontal extension portion 71 'is short. Therefore, the mounting structure and the mounting method are the same as those in the second embodiment.
In short, the suspension metal fittings 7 and 7 ′ shown in the second and third embodiments can adapt to the various convex and concave portions of the deck plate 2 only by changing the length of the arm material 71b, and are highly versatile. There are advantages.

In the second and third embodiments, the horizontal extending portions 71 and 71 ′ of the hanging metal fittings 7 and 7 ′ are provided with elastic means for exerting elastic force, and the jaw portion 22a of the convex peak portion 20 can be held by the elastic force. However, the present invention is not limited to this, and the same can be implemented by the elastic means shown in FIGS.
In short, the hanging metal fitting 8 used in the fourth embodiment employs a clamp structure as elastic means provided in the horizontal extension portion 81.
As shown in FIGS. 12A and 12B, the horizontal extension 81 includes a plate 81a extending from the top of the suspension 80 in a direction orthogonal to the suspension direction, and a horizontal pressing arm extending in the horizontal direction from the left and right ends of the plate 81a. 81b and 81b, and the clamp part 81c which has the rotation means 81d which is connected to the plate 81a and can be rotated.
The left horizontal pressing arm 81b is connected to the vicinity of the rotating means 81d of the clamp portion 81c, and the right horizontal pressing arm 81b rotates to an arm support portion 81e provided at the right end of the plate 81a. Supported as possible. The holding parts 82, 82 having a pair of stepped parts 82a, 82a are connected to both ends of the left and right horizontal pressing arms 81b in the same manner as the above-described hanging metal fittings 1, 7, 7 ′. Therefore, if the clamp part 81c is raised upward to release the fixed state of the horizontal pressing arm 81b, the left and right horizontal pressing arms 81b can be freely rotated, and the convex peak part 20 can be aligned with the jaw part 22a. Easy to do. Furthermore, after the positioning of the hanging bracket 8 is performed, the clamp portion 81c is lowered, and the hanging bracket 8 is firmly attached to the protruding peak portion 20 of the deck plate 2 by its elastic force.
