  There is a technology related to a so-called system ceiling in which a suspended ceiling formed by beams and ceiling panels is suspended from a ceiling slab using suspension bolts. In such a system ceiling technology, it is desired to develop a technology that is more excellent in workability and strength.

  In view of the above problems, an object of the present invention is to provide a technique relating to a suspension structure that is excellent in workability and excellent in strength.

The present invention employs the following means in order to solve the above-described problems. That is, the present invention suspends, from a ceiling slab, a beam member having a groove extending along the axial direction and having a groove having an opening narrower than a space in the groove in a cross section orthogonal to the axial direction. A hanging structure including a hanging device for lowering, wherein the hanging device is connected to a rod-shaped hanging member connected to the ceiling slab, and a connection portion for a hanging member of the hanging device, and a connection for a hanging member of the hanging device. A shaft portion of the suspending device connected to the portion and extending downward, and a beam member supporting portion of the suspending device connected to the shaft portion of the suspending device and supporting the beam member. A support member for the beam member of the first suspension device which is located below the connection portion for the suspension member of the suspension device and is inserted into the groove to support the beam member; Located diagonally below the connection part and on the groove, it is slidable in the groove It is connected to the connection device including a beam member supporting portion of the second hanging device for supporting the beam member.

  In the suspension structure according to the present invention, the suspension device includes the beam member support portion of the first suspension device and the beam member support portion of the second suspension device, and supports the beam member at a plurality of locations. Therefore, for example, the strength of the system ceiling including the beam members and the suspension structure can be improved as compared with a suspension device that supports the beam members at one place. The number of beam member support portions of the second suspension device is not particularly limited, but the beam member support portion of the second suspension device may be, for example, a groove portion based on the beam member support portion of the first suspension device. It is good to provide two places on both sides of the upper part. Thereby, the strength of the system ceiling can be further improved. Further, although the suspension device supports the beam member at a plurality of positions, the support portion for the beam member of the first suspension device need only be inserted into the groove. Therefore, workability can be improved as compared with the case where all of the plurality of locations are fixed with bolts, nuts, or the like.

  As an example, the coupling device can be moved to an arbitrary position along the groove, and can be fixed to the position inside the groove, which is surrounded by an inner wall in a cross section and has an opening in a part, and a suspension device or A base member having a connecting portion for connecting with the steady rest device, and an auxiliary member made of a flexible member configured to be separable from the base member, wherein the base member is placed in the groove. And an auxiliary member including a main body that urges the inner wall of the groove, and an arm that extends from an end of the main body and that has a tip exposed from the opening. Things.

  In the connecting device according to the present invention, the connecting device itself can be moved to an arbitrary position along the groove by moving the base member in the groove. Then, the main body of the auxiliary member made of a flexible member is housed in the groove, and by urging the inner wall of the groove, the connecting device itself can be temporarily fixed at the arbitrary position. Temporary fixing is a state in which the connecting device is movable by applying a certain force such as holding it by hand. The fixing according to the present invention includes, in addition to the temporary fixing, a state in which the movement is restricted by using a member such as a screw. In addition, since the base member and the auxiliary member are configured by separate members that can be separated from each other, the connecting device can be moved more smoothly in the groove when both are separated. The main body and the arm are made of a flexible member. The flexible member is a thin plate-shaped member that bends when an external force is applied. In other words, in the connecting device according to the present invention, the main body on which the base member is placed can be constituted by a thin plate-shaped member, and the arms extend from the end of the main body. Can be secured. Therefore, the base member can be made thicker than before, and the strength of the base member can be improved more than before. In addition, since the arm extends from the end of the main body, the movement of the base member placed on the main body in the longitudinal direction of the groove can be restricted. Furthermore, since the tip of the arm is exposed from the opening, the auxiliary member can be easily taken out of the groove by pinching the tip of the arm. In addition, since the base member and the auxiliary member are configured by separate members that can be separated, the base member and the auxiliary member can be separately put in and out of the groove. Therefore, even if the base member is thicker than before, it can be easily put in and out of the groove. In other words, the connecting device of the present invention can easily perform the work of attaching to the inside of the groove and the work of taking out from the inside of the groove, and is easy to handle.

  Here, the suspension structure according to the present invention further includes a steady rest device that suppresses the swing of the beam member, and the steady rest device is connected to the suspending member, and a connecting portion for a suspending member of the steady rest device.

  Further, the steady rest device is freely connectable to the suspending device, and the suspending member connecting portion of the steady rest device regulates movement of the suspending member connecting portion of the suspending device. May be included.

  The suspension device and the steadying device can be used separately. However, by connecting the steadying device to the suspending device and restricting the movement of the suspending device by the regulating portion of the steadying device, an integrated unit is obtained. As a result, the suspension device and the steady rest device become stronger, and the strength of the system ceiling can be further improved. In addition, the integration improves the beauty of the system ceiling.

  Further, the steady rest device is freely connectable to the suspending device, and the beam member supporting portion of the steady rest device is on the groove, and based on the beam member supporting portion of the first suspending device. The beam member may be supported by being connected to a connection device that is slidable in the groove outside the beam member support portion of the second suspension device.

  By supporting the beam member outside the beam member support portion of the second suspension device, a sufficient interval between the beam member support portions of the steady rest device is ensured. Therefore, the strength of the system ceiling can be further improved. In the aspect in which the beam member is supported outside the beam member supporting portion of the second suspension device, the case where the steady rest device is connected to the suspension device, the case where the steady rest device and the suspension device are not connected, and Is included. In the latter case, based on the beam member support of the first suspension device, the outside of the beam member support of the second suspension device is assumed to be that the steady rest device is connected to the suspension device. This is a virtual position in the case of having performed. When the steadying device is connected to the suspension device, the beam member supporting portion of the steadying device supports the beam member so as to sandwich the beam member supporting portion of the second suspending device. Therefore, the integration between the steady rest device and the suspension device is further improved. As a result, the strength of the system ceiling can be further improved.

  Further, the brace material connecting portion of the steady rest device may be a vertical plate having a plurality of connection holes for connecting to the brace material and extending in a direction parallel to the axis and in a vertical direction. The brace material can be supported on the surface by making the connection part for the brace material of the steady rest device a vertical plate, that is, a plate shape. For this reason, the strength of the connection portion between the brace material connecting portion of the steady rest device and the brace material can be improved as compared with the case of supporting at a point. The plurality of connection holes formed in the vertical plate can be selectively used according to, for example, the connection angle of the brace material.

  Further, the beam member has an accommodating portion formed by an outer wall of the opposing beam member extending upward from a side surface of the beam member and an upper surface of the beam member, and having an open upper portion. A part below a part of a shaft part of the device may be housed in the housing part, and the steadying device may be housed in the housing part below a part of a shaft part of the steadying device. Accordingly, the connection between the suspension device and the beam member and the connection between the steady rest device and the suspension device are covered with the housing portion, and are difficult to be visually recognized from the outside. As a result, the beauty of the system ceiling is improved.

It is formed at a position higher than the beam member support portion 531. Further, a screw hole 533 of a horizontal plate through which the screw N1 penetrates is formed in the beam member support portion 532 of the second suspension device including the two horizontal plates when the fixing member is fixed to the connecting device 8 using the screw N1. ing.

  Here, FIG. 15 is a diagram illustrating a connection member that connects the beam member and the suspension device according to the embodiment, as viewed from the axial direction of the beam member. FIG. 16 is an exploded perspective view of the connecting member according to the embodiment. In the suspension device 5, the support portion 532 for the beam member of the second suspension device and the steadying device 7 are aligned with the screw holes 811 of the coupling device of the coupling device 8 that can slide in the groove 25 of the beam member 2. By screwing the screw N <b> 1, the suspension member 4 and the steady rest device 7 can be fixed to the beam member 2.

  The connection device 8 includes a base member 81 and an auxiliary member 82. The base member 81 is rectangular in plan view, and has a screw hole 811 of the base member at the center. At the end (the both ends in the width direction of the groove 25) of the surface (the surface of the groove 25 on the opening 24 side) of the base member 81, a step formed one step lower than the surface along the length of the groove 25. An attachment portion 83 is provided. The space between the two stepped portions 83 is designed to be slightly smaller than the width of the opening 24 of the beam member 2. The lid 26 forming the opening 24 is engaged with each stepped portion 83. Thus, the movement of the base member 81 in the width direction of the groove 25 in the groove 25 is restricted. Further, an end portion (both ends in the width direction of the groove portion 25) of a back surface (a back surface of the groove portion 25) of the base member 81 is chamfered 84 so as to match a shape of the groove whose width decreases toward the back. ing.

  The auxiliary member 82 includes a main body 821 on which the base member 81 is placed in the groove 25, and two arms 822 extending from ends of the main body 821. The auxiliary member 82 is made of a flexible plate-shaped resin, and the main body 821 and the arm 822 are formed integrally. The main body 821 is curved so as to protrude to the inner side of the groove 25. The main body 821 is designed to have an area larger than the surface area of the base member 81 so that the base member 81 can be placed thereon. At the center of the main body 821, in other words, at a position corresponding to the screw hole 811 of the base member, a screw hole 823 of the main body through which the screw N1 passes is provided. A plurality of screw holes 823 in the main body may be provided. In addition, a thick portion 825 is formed on one side of the main body 821 so as to be thicker on the opening 24 side than on the periphery. The thick portion 825 restricts movement of the mounted base member 81 in the width direction of the groove, and functions as a region for pressing the auxiliary member 82 when the auxiliary member 82 is attached (accommodated) to the groove 25. . By pressing the thick portion 825, the auxiliary member 82 can be easily attached to the groove 25. The thick portion 825 also functions as a fulcrum when the arm member 822 is pinched to take out the auxiliary member 82 from the groove 25. That is, when the thick portion 825 comes into contact with the inner wall surface of the groove 25 and becomes a fulcrum, and the arm 822 is pinched and pulled out from the groove 25, the main body 821 of the auxiliary member 82 is taken out from the groove 25.

  In the main body 821, the thick portion 825 and the bent portion 824 of the other piece come into contact with the inner wall of the groove 25, and urge the inner wall of the groove 25 toward the outside of the width of the groove 25. Thus, the auxiliary member 82 is temporarily fixed in the groove 25. More specifically, when the main body 821 does not mount the base member 81 (only the auxiliary member 82 is accommodated in the groove 25), the thick portion 825 and the bent portion 824 are formed on the inner wall of the groove 25. The inner wall of the groove 25 is urged toward a region (vertical plane) where the width of the groove 25 is constant toward the outside of the width of the groove 25. When the main body 821 has the base member 81 placed thereon (both the auxiliary member 82 and the base member 81 are accommodated in the groove 25), the thick portion 825 and the bent portion 824 are formed on the inner wall of the groove 25. Of these, the inner wall of the groove 25 is urged toward a region (slope) where the width of the groove 25 gradually decreases toward the outside of the width of the groove 25. In a state where the main body 821 has the base member 81 placed thereon, a part of the urging force is also generated on the inner side of the groove 25 along the slope.

  The main body 821 is formed such that one side is shorter than the other side. In detail, in the main body 821, the length of one side where the thick portion 825 is formed is shorter by two arms 822 than the length of the other side where the bent portion 824 is formed. Is formed. In other words, on one side of the main body 821, both sides in the longitudinal direction of the groove 25 are cut out. The biasing force is adjusted by forming the notch in a part as described above.

  The arm portion 822 is provided at two positions via bent portions 824 provided at both ends of the other side opposite to the thick portion 825.
