[0003] [Patent Document 1] JP 2021-165472 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the slab deck mounting fixture described in Patent Document 1, the deck-side fixing part is configured to be inserted into a hole formed in the slab deck and fixed, so it is necessary to form a hole in the slab deck in advance for inserting the deck-side fixing part. Therefore, prior to the mounting work using the slab deck mounting fixture, a preparatory work is required to form a hole in the slab deck, and in addition, it is time-consuming to determine the drilling position so that the fixing part on the mounted part side of the slab deck mounting fixture can be appropriately fixed to the mounted part. In view of this situation, the main object of the present invention is to provide a slab deck mounting fixture that, when used to mount a slab deck to a mounting portion on the main body, can fix each fixing portion of the slab deck mounting fixture without fire, thereby contributing to fire prevention, while easily mounting the slab deck to the mounting portion on the main body without the need for complicated preparatory work, thereby reliably preventing the slab deck from shifting or falling. [Means for solving the problem]

[0005] The first characteristic configuration of the present invention is a deck side fixing part that is fixed to the slab deck in a fire-free state, A mounting portion side fixing portion that is fixed to the mounting portion in a fire-free state; a main body portion connecting the deck side fixing portion and the attachment portion side fixing portion, A slab deck mounting tool for mounting the slab deck to the mounting portion, The deck-side fixing portion is configured so as to be fixable to the slab deck by screws.

[0006] With this configuration, the fixing part on the mounting part side can be fixed to the mounting part in a fire-free state that does not cause a fire due to welding or the like, and the fixing part on the deck side can be easily and reliably fixed to the slab deck with screws that do not cause a fire due to welding or the like. Therefore, according to the present invention, it is possible to provide a slab deck mounting fixture which, when using a slab deck mounting fixture to mount a slab deck to an attachment portion, contributes to fire prevention by fixing each fixing portion of the slab deck mounting fixture in a fire-free state that does not generate fire due to welding or the like, while at the same time, without the need for complicated preparatory work, the slab deck mounting fixture fixed to the attachment portion can be fixed to the slab deck with simple screws, thereby reliably preventing the slab deck from shifting or falling.

[0007] A second characteristic configuration of the present invention is that the mounting portion is a rod-shaped portion on the body side, The attachment portion side fixed portion is configured so as to be fixed to the rod-shaped portion by a hook.

[0008] According to this configuration, the mounting portion can be a rod-shaped portion fixed to the structure, such as a beam on which the slab deck rests. When the rod-shaped portion on the structure is used as the mounting portion, the mounting portion side fixing portion can be easily and reliably fixed to the rod-shaped portion on the structure by welding or the like without causing a fire.

[0009] A third characteristic configuration of the present invention is a linear main body portion made of a rod material extending in a substantially linear manner, The deck side fixing portion is provided at one end of the bar material, The attachment side fixing portion is formed in a hook shape at the other end of the bar.

[0010] According to this configuration, the mounting side fixing part formed in a hook shape at the other end of the straight main body part can be fixed to the rod-shaped portion on the body side which is the mounting part with a hook, and then the deck side fixing part provided at one end of the straight main body part can be easily fixed to the slab deck with screws.

[0011] A fourth characteristic configuration of the present invention is a U-shaped main body portion made of a rod material bent into a substantially U-shape, The deck side fixing portion is provided on each of both ends of the main body portion, The folded-back portion of the U-shaped main body is wound around the rod-shaped portion on the body side as the attached portion-side fixed portion.

[0012] According to this configuration, the folded-back portion of the U-shaped main body is wrapped around the rod-shaped portion of the frame as the attached portion-side fixed portion, and the deck-side fixed portions provided on both ends of the U-shaped main body can be easily fixed to the slab deck with screws. Furthermore, since both ends of the U-shaped main body are closed by the deck-side fixed portions fixed to the slab deck, it is possible to reliably prevent the attached portion-side fixed portions from coming off the rod-shaped portion of the frame as the attached portion.

[0013] A fifth characteristic configuration of the present invention is a flexible main body portion made of a flexible wire or band material, The deck side fixing portion is provided on each of both ends of the main body portion, The central portion of the flexible main body is wound around the rod-shaped portion on the body side as the attachment portion-side fixed portion.

[0014] According to this configuration, the flexible body is bent into a substantially U-shape at the construction site, and the central portion is wrapped around the rod-shaped portion of the frame side that is the part to be attached as the attached portion-side fixed portion, and the deck-side fixed portions provided on both ends of the flexible body can be easily fixed to the slab deck with screws. Furthermore, since both ends of the flexible body are closed by the deck-side fixed portions fixed to the slab deck, it is possible to reliably prevent the attached portion-side fixed portions from coming off the rod-shaped portion of the frame side that is the part to be attached.

[0015] A sixth characteristic configuration of the present invention is that the deck side fixing portion and the main body portion are configured separately, The end of the main body is provided with a deck-side hook portion that is hooked onto the deck-side fixed portion fixed to the slab deck.

[0016] According to this configuration, the main body and the deck side fixing part are constructed separately, so that they can be constructed from different types of components, for example, by constructing the main body from rod material with excellent tensile strength and the deck side fixing part from a plate material with excellent workability for screwing. The main body and the deck-side fixing part can be easily connected by hooking the deck-side hooking part provided at the end of the main body to the deck-side fixing part fixed to the slab deck with screws.

[0018] [First embodiment] A first embodiment of a slab deck fastener according to the present invention will be described with reference to Figs. As shown in FIG. 1, the slab deck mounting fixture 10 of this embodiment is configured as a mounting fixture for mounting the slab deck 1 to a specified mounting portion A in order to prevent the slab deck 1 from shifting or falling during construction in which the slab deck 1 is erected on a beam 3 (an example of a structural body).

[0019] The slab deck mounting fixture 10 has a deck-side fixing part 16 which is fixed to the slab deck 1 in a fire-free state, a mounting-part-side fixing part 14 which is fixed to the mounting part A in a fire-free state, and a main body part 12 which connects the deck-side fixing part 16 and the mounting-part-side fixing part 14. By using this slab deck mounting fixture 10, the slab deck 1 can be mounted to the mounting part A in a fire-free state without welding, which contributes to fire prevention. Furthermore, by attaching the slab deck 1 to the mounting portion A using the slab deck mounting fixture 10, the slab deck mounting fixture 10 fixed to the mounting portion A can be fixed to the slab deck 1 by simply screwing it using screws 5, without the need for complicated preparation work, thereby reliably preventing the slab deck 1 from shifting or falling.The detailed configuration for achieving this is explained below.

[0020] 1, 2, and 3, the deck-side fixing part 16 is configured to be fixable to the slab deck 1 by screwing using screws 5. That is, the deck-side fixing part 16 is provided with a plurality of screw insertion holes 16a through which the screws 5 are inserted, and the deck-side fixing part 16 is fixed to the slab deck 1 by screwing the plurality of screws 5 inserted into the screw insertion holes 16a into the slab deck 1. With this configuration, the mounting side fixing part 14 can be fixed to the mounting part A in a fire-free state that does not cause a fire due to welding or the like, and then the deck side fixing part 16 can be easily and reliably fixed to the slab deck 1 by screwing with screws 5 that do not cause a fire due to welding or the like.

[0021] The attached part A is a stirrup bar 3a (an example of a rod-shaped part on the frame side) partially exposed on the upper side of a beam 3 made of reinforced concrete (RC), and the attached part side fixing part 14 is configured so as to be able to be fixed to the stirrup bar 3a by hooking. With this configuration, for example, the stirrup bar 3a fixed to the beam 3 on which the slab deck 1 is placed can be used as the attached part A, and the attached part side fixing part 14 can be easily and reliably fixed to the stirrup bar 3a by hooking without generating fire by welding or the like.

[0022] Furthermore, in the slab deck fixture 10 of this embodiment, the main body 12 is configured as a linear main body 12 made of a bar material such as a steel bar extending in a substantially straight line. One end of the bar material constituting the straight main body portion 12 is crushed into a flat plate, and the flat portion at one end serves as the deck-side fixing part 16 having screw insertion holes 16a drilled therein, and is fixed to the slab deck 1 with screws, as shown in Fig. 1. In order to prevent wobbling when the deck-side fixing part 16 is fixed to the slab deck 1, the lower surface of the deck-side fixing part 16 that abuts against the slab deck 1 is made flush with the outer circumferential surface of the straight main body portion 12, and the deck-side fixing part 16 is formed so that a step is provided between the outer circumferential surface of the straight main body portion 12 and the upper surface of the deck-side fixing part 16 only on the upper surface side. On the other hand, the other end of the rod material constituting the linear main body portion 12 is bent into a hook shape, and the hook-shaped portion serves as the fixed portion 14 on the attachment side and is fixed to the stirrup bar 3a by a hook fastener, as shown in FIG. 1. With this configuration, the mounting side fixing part 14 formed in a hook shape at the other end of the straight main body part 12 can be fixed to the mounting part A, i.e., the stirrup bar 3a, by a hook fastener, and then the deck side fixing part 16 provided at one end of the straight main body part 12 can be easily fixed to the slab deck 1 by screwing using screws 5.

[0023] In this embodiment, the beam 3 is made of reinforced concrete, but it may be a beam made of steel or wood. In this embodiment, the attached part A to which the attached part side fixing part 14 is fixed is the stirrup bar 3a partially exposed on the upper side of the reinforced concrete beam 3 on which the slab deck 1 is placed, but any part fixed to the beam, such as another reinforcing bar such as a main bar fixed to the stirrup bar 3a, a stud dowel fixed to the upper surface of a steel or wood beam, or a drift pin or support metal fixed to the beam, can be used as the attached part A. Furthermore, this attached part A does not have to be fixed to the beam 3, and it may be a part fixed to a body side other than the beam, such as a column or a wall.

[0024] Second Embodiment A second embodiment of a slab deck fastener according to the present invention will be described with reference to Figs. As shown in FIG. 4, the slab deck mounting fixture 20 of this embodiment is configured as a mounting fixture for mounting the slab deck 1 to a specified mounting portion A in order to prevent the slab deck 1 from shifting or falling during construction in which the slab deck 1 is erected on a beam 3 (an example of a structural body).

[0025] The slab deck mounting fixture 20 has a deck-side fixing part 26 that is fixed to the slab deck 1 in a fire-free state, a mounting-part-side fixing part 24 that is fixed to the mounting part A in a fire-free state, and a main body part 22 that connects the deck-side fixing part 26 and the mounting-part-side fixing part 24. By using this slab deck mounting fixture 20, the slab deck 1 can be mounted to the mounting part A in a fire-free state without welding, which contributes to fire prevention. Furthermore, by attaching the slab deck 1 to the mounting portion A using the slab deck mounting fixture 20, the slab deck mounting fixture 20 fixed to the mounting portion A can be fixed to the slab deck 1 by simply screwing it using screws 5, without the need for complicated preparation work, thereby reliably preventing the slab deck 1 from shifting or falling.The detailed configuration for achieving this is explained below.

[0026] 4, 5, and 6, the deck-side fixing part 26 is configured to be fixable to the slab deck 1 by screwing using screws 5. That is, the deck-side fixing part 26 is provided with a plurality of screw insertion holes 26a through which the screws 5 are inserted, and the deck-side fixing part 26 is fixed to the slab deck 1 by screwing the plurality of screws 5 inserted into the screw insertion holes 26a into the slab deck 1. With this configuration, the mounting portion side fixing part 24 can be fixed to the mounting portion A in a fire-free state that does not cause a fire due to welding or the like, and then the mounting portion side fixing part 24 can be easily and reliably fixed to the slab deck 1 by screwing using screws 5 that do not cause a fire due to welding or the like.

[0027] The attached part A is a stirrup bar 3a (an example of a rod-shaped part on the frame side) partially exposed on the upper side of a beam 3 of reinforced concrete (RC), and the attached part side fixing part 24 is configured so as to be able to be fixed to the stirrup bar 3a by hooking. With this configuration, for example, the stirrup bar 3a fixed to the beam 3 on which the slab deck 1 is placed can be used as the attached part A, and the attached part side fixing part 24 can be easily and reliably fixed to the stirrup bar 3a on the beam 3 side by hooking that does not generate fire by welding or the like.

[0028] Furthermore, in the slab deck mounting fixture 20 of this embodiment, the main body 22 is configured as a U-shaped main body 22 made of a bar material such as a steel bar that is bent into an approximate U shape at a folding portion approximately in the center. Both ends of the bar material constituting the U-shaped main body portion 22 are crushed into a flat plate, and each of the flat portions on both ends becomes the deck-side fixing part 26 having a screw insertion hole 26a formed therein, and is fixed to the slab deck 1 with a screw, as shown in Fig. 4. In order to prevent wobbling when the deck-side fixing part 26 is fixed to the slab deck 1, the lower surface of the deck-side fixing part 26 that abuts against the slab deck 1 is made flush with the outer circumferential surface of the linear main body portion 22, and the deck-side fixing part 26 is formed so that a step is provided only on the upper surface side between the outer circumferential surface of the linear main body portion 22 and the upper surface of the deck-side fixing part 26. The folded-back portion of the U-shaped main body 22 serves as a fixing portion 24 on the attachment side, and is wound around the stirrup bar 3a as shown in FIG.

[0029] With this configuration, with the folded-back portion of the U-shaped main body 22 wrapped around the stirrup bars 3a, which are the attached part A, as the attached part side fixed part 24, the deck side fixed parts 26 provided on both ends of the U-shaped main body 22 can be easily fixed to the slab deck 1 by screwing using the screws 5. Furthermore, since both ends of the U-shaped main body 22 are closed by the deck side fixed parts 26 fixed to the slab deck 1, the attached part side fixed parts 24 are reliably prevented from coming off the stirrup bars 3a.

[0030] In this embodiment, the beam 3 is made of reinforced concrete, but it may be a beam made of steel or wood. In this embodiment, the attached part A to which the attached part side fixing part 14 is fixed is the stirrup bar 3a partially exposed on the upper side of the reinforced concrete beam 3 on which the slab deck 1 is placed, but any part fixed to the beam, such as another reinforcing bar such as a main bar fixed to the stirrup bar 3a, a stud dowel fixed to the upper surface of a steel or wood beam, or a drift pin or support metal fixed to the beam, can be used as the attached part A. Furthermore, this attached part A does not have to be fixed to the beam 3, and it may be a part fixed to a body side other than the beam, such as a column or a wall.

[0031] Third Embodiment A third embodiment of a slab deck fastener according to the present invention will be described with reference to Figs. As shown in FIG. 7, the slab deck mounting fixture 30 of this embodiment is configured as a mounting fixture for mounting the slab deck 1 to a specified mounting portion A in order to prevent the slab deck 1 from shifting or falling during construction in which the slab deck 1 is erected on a beam 3 (an example of a structural body).

[0032] The slab deck mounting fixture 30 has a deck-side fixing part 36 which is fixed to the slab deck 1 in a fire-free state, a mounting-part-side fixing part 34 which is fixed to the mounting part A in a fire-free state, and a main body part 32 which connects the deck-side fixing part 36 and the mounting-part-side fixing part 34. By using this slab deck mounting fixture 30, the slab deck 1 can be mounted to the mounting part A in a fire-free state without welding, which contributes to fire prevention. Furthermore, by attaching the slab deck 1 to the mounting portion A using the slab deck mounting fixture 30, the slab deck mounting fixture 30 fixed to the mounting portion A can be fixed to the slab deck 1 by simply screwing it using screws 5, without the need for complicated preparation work, thereby reliably preventing the slab deck 1 from shifting or falling.The detailed configuration for achieving this is explained below.

[0033] 7 and 8, the deck-side fixing part 36 is configured to be fixable to the slab deck 1 by screwing using screws 5. That is, the deck-side fixing part 36 is provided with a plurality of screw insertion holes 36a through which the screws 5 are inserted, and the deck-side fixing part 36 is fixed to the slab deck 1 by screwing the plurality of screws 5 inserted into these screw insertion holes 36a into the slab deck 1. With this configuration, the mounting side fixing part 34 can be fixed to the mounting part A in a fire-free state that does not cause fire due to welding or the like, and then the deck side fixing part 36 can be easily and reliably fixed to the slab deck 1 by screwing with screws 5 that do not cause fire due to welding or the like.

[0034] The attached part A is a stirrup bar 3a (an example of a rod-shaped part on the frame side) partially exposed on the upper side of a beam 3 of reinforced concrete (RC), and the attached part side fixing part 34 is configured so as to be able to be fixed to the stirrup bar 3a by hooking. With this configuration, for example, the stirrup bar 3a fixed to the beam 3 on which the slab deck 1 is placed can be used as the attached part A, and the attached part side fixing part 34 can be easily and reliably fixed to the stirrup bar 3a on the beam 3 side by hooking that does not generate fire by welding or the like.

[0035] Furthermore, in the slab deck fixture 30 of this embodiment, the main body 32 is configured as a flexible main body 32 made of a flexible steel wire (an example of a wire material) or the like. A flat plate is pre-joined to each of both ends of the flexible main body 32 by welding, and each of these plates at both ends serves as a deck-side fixing part 36 having a screw insertion hole 36a formed therein, and is fixed to the slab deck 1 by screws, as shown in Figure 7. Further, the approximate center portion of the flexible main body portion 32 is used as the attachment side fixing portion 34, and is wound around the stirrup bar 3a as shown in FIG.

[0036] With this configuration, the flexible main body 32 made of steel wire or the like can be bent into a substantial U-shape at the construction site, and its central portion can be wound around the stirrup bars 3a, which are the attached part A, as the attached part side fixing part 34. Then, the deck side fixing parts 36 provided on both ends of the flexible main body 32 can be easily fixed to the slab deck 1 by screwing using the screws 5. Furthermore, since both ends of the flexible main body 32 are closed by the deck side fixing parts 36 fixed to the slab deck 1, the attached part side fixing parts 34 are reliably prevented from coming off the attached part A, which is the stirrup bars 3a.

[0037] In this embodiment, the beam 3 is made of reinforced concrete, but it may be a beam made of steel or wood. In this embodiment, the attached part A to which the attached part side fixing part 14 is fixed is the stirrup bar 3a partially exposed on the upper side of the reinforced concrete beam 3 on which the slab deck 1 is placed, but any part fixed to the beam, such as another reinforcing bar such as a main bar fixed to the stirrup bar 3a, a stud dowel fixed to the upper surface of a steel or wood beam, or a drift pin or support metal fixed to the beam, can be used as the attached part A. Furthermore, this attached part A does not have to be fixed to the beam 3, and it may be a part fixed to a body side other than the beam, such as a column or a wall.

[0038] In the usage form shown in Fig. 7, instead of the slab deck fixture 30 (see Fig. 8), a slab deck fixture 40 of another form shown in Fig. 9 can be used. The configuration of the slab deck fixture 40 will be explained below. In the slab deck fixture 40, the main body 42 is configured as a flexible main body 42 made of flexible steel wire (an example of a wire material) or the like. A flat plate is fixed to each end of the flexible main body 42, and each of the plates at each end serves as a deck-side fixing part 46 having a screw insertion hole 46a formed therein, and is fixed to the slab deck 1 with screws in the same manner as the slab deck fixture 30 (see FIG. 8).

[0039] Furthermore, as shown in FIG. 9, the deck side fixing portion 46 and the flexible main body portion 42 are constructed as separate bodies, and each end of the flexible main body portion 42 is bent into an L shape to provide a deck side hanging portion 45 that is hung on the deck side fixing portion 46 fixed to the slab deck 1. In other words, since the flexible main body portion 42 and the deck side fixing portion 46 are constructed separately, they can be constructed from different types of materials, for example, by constructing the main body portion 42 from a rod material with excellent tensile strength and the deck side fixing portion 46 from a plate material with excellent workability for screwing using screws 5. The flexible main body portion 42 and the deck side fixing portion 46 are fixed to the slab deck 1 by screwing the deck side fixing portion 45, which is provided at the end of the flexible main body portion 42, with screws 5, so that the flexible main body portion 42 and the deck side fixing portion 46 can be easily connected to each other.

With this configuration, the mounting side fixing part 54 can be fixed to the mounting part A in a fire-free state that does not cause fire due to welding or the like, and then the deck side fixing part 56 can be easily and reliably fixed to the slab deck 1 by screwing using screws 5 that do not cause fire due to welding or the like.

[0043] The attached part A is a stirrup bar 3a (an example of a rod-shaped part on the frame side) partially exposed on the upper side of a beam 3 made of reinforced concrete (RC), and the attached part side fixing part 54 is configured so as to be able to be fixed to the stirrup bar 3a by hooking. With this configuration, for example, the stirrup bar 3a fixed to the beam 3 on which the slab deck 1 is placed can be used as the attached part A, and the attached part side fixing part 54 can be easily and reliably fixed to the stirrup bar 3a on the beam 3 side by hooking that does not generate fire by welding or the like.

[0044] Furthermore, in the slab deck fixture 50 of this embodiment, the main body 52 is configured as a flexible main body 52 made of a flexible steel strip (an example of a strip material) or the like. Each of the two ends of the flexible main body 52 serves as a deck-side fixing portion 56 having a screw insertion hole 56a formed therein, and is fixed to the slab deck 1 with a screw, as shown in FIG. Further, the approximate center portion of the flexible main body portion 52 is used as the attachment side fixing portion 54, and is wound around the stirrup bar 3a as shown in FIG.

[0045] With this configuration, the flexible main body 52 made of band steel or the like can be folded into a substantial U-shape at the construction site, and its central portion can be wrapped around the stirrup bars 3a, which are the attached part A, as the attached part side fixed part 54, and the deck side fixed parts 56 at both ends of the flexible main body 52 can be easily fixed to the slab deck 1 by screwing using the screws 5. Furthermore, since both ends of the flexible main body 52 are closed by the deck side fixed parts 56 fixed to the slab deck 1, the attached part side fixed parts 54 are reliably prevented from coming off the attached part A, which is the stirrup bars 3a.

[0046] In this embodiment, the beam 3 is made of reinforced concrete, but it may be a beam made of steel or wood. In this embodiment, the attached part A to which the attached part side fixing part 14 is fixed is the stirrup bar 3a partially exposed on the upper side of the reinforced concrete beam 3 on which the slab deck 1 is placed, but any part fixed to the beam, such as another reinforcing bar such as a main bar fixed to the stirrup bar 3a, a stud dowel fixed to the upper surface of a steel or wood beam, or a drift pin or support metal fixed to the beam, can be used as the attached part A.

Furthermore, by attaching the slab deck 1 to the mounting portion A using the slab deck mounting fixture 60, the slab deck mounting fixture 60 fixed to the mounting portion A can be fixed to the slab deck 1 by simply screwing it using the screws 5, without the need for complicated preparation work, thereby reliably preventing the slab deck 1 from shifting or falling.The detailed configuration for achieving this is explained below.

[0049] 12, 13, and 14, the deck-side fixing part 66 is configured to be fixable to the slab deck 1 by screwing using screws 5. That is, the deck-side fixing part 66 is provided with a plurality of screw insertion holes 66a through which the screws 5 are inserted, and the deck-side fixing part 66 is fixed to the slab deck 1 by screwing the plurality of screws 5 inserted into these screw insertion holes 66a into the slab deck 1. With this configuration, the mounting side fixing part 64 can be fixed to the mounting part A in a fire-free state that does not cause fire due to welding or the like, and then the deck side fixing part 66 can be easily and reliably fixed to the slab deck 1 by screwing using screws 5 that do not cause fire due to welding or the like.

[0050] The mounted portion A is another slab deck (hereinafter referred to as the "opposing slab deck") 2 arranged facing the slab deck 1 with a beam 3 in between, and the mounted portion side fixing portion 64 is configured so as to be fixable to the opposing slab deck 2 by screwing using screws 5. That is, like the deck side fixing portion 66, the mounted portion side fixing portion 64 is provided with a plurality of screw insertion holes 64a through which the screws 5 are inserted, and the deck side fixing portion 66 is fixed to the slab deck 1 by screwing the plurality of screws 5 inserted into these screw insertion holes 64a into the opposing slab deck 2. With this configuration, the opposing slab deck 2, which is arranged facing the slab deck 1 with the beam 3 in between, can be used as the mounting part A, and the opposing slab deck 2 can be easily and reliably fixed by screwing with screws 5 that do not generate fire due to welding or the like.

[0051] Furthermore, in the slab deck mounting fixture 60 of this embodiment, the main body 62 is configured as a linear main body 62 made of a bar material such as a steel bar extending in a substantially straight line. One end of the rod material constituting the straight main body portion 62 is crushed into a flat plate, and the flat portion at that end serves as the deck side fixing portion 66 having a screw insertion hole 66a drilled therein, and is fixed to the slab deck 1 with a screw, as shown in Figure 12. Meanwhile, the other end of the bar constituting the straight main body portion 62 is crushed into a flat plate like the deck side fixing portion 66, and the flat portion on the other end side serves as the attached portion side fixing portion 64 having a screw insertion hole 64a formed therein, and is fixed to the opposing slab deck 2 with a screw as shown in Fig. 12. Here, in order to prevent wobbling when the deck side fixing portion 66 and the attached portion side fixing portion 64 are fixed to the slab decks 1 and 2, the lower surfaces of the deck side fixing portion 66 and the attached portion side fixing portion 64 that come into contact with the slab decks 1 and 2 are made flush with the outer circumferential surface of the straight main body portion 62, and the deck side fixing portion 66 and the attached portion side fixing portion 64 are formed so that a step is provided only on the upper surface side between the outer circumferential surface of the straight main body portion 62 and the upper surfaces of the deck side fixing portion 66 and the attached portion side fixing portion 64. With this configuration, with the straight main body portion 62 passing through the space below the main reinforcement 3b of the beam 3, the attached part side fixing portion 64 formed in a flat plate shape at the other end of the straight main body portion 62 can be fixed to the attached part A, which is the opposing slab deck 2, by screwing using a screw 5, and then the deck side fixing portion 66 provided at one end of the straight main body portion 62 can be simply fixed to the slab deck 1 by screwing using a screw 5.

[0052] Furthermore, by attaching the slab deck 1 to the opposing slab deck 2 with the slab deck mounting fixture 60 in this manner, when the slab deck 1 attempts to fall off the beam 3, as the slab deck 1 moves away from the beam 3, the opposing slab deck 2 moves towards the beam 3 and the end of the opposing slab deck 2 abuts against the stirrup bars 3a of the beam 3, etc., thereby preventing the movement of the slab decks 1, 2 and as a result, preventing the slab deck 1 from falling off the beam 3.
