Description

  The present invention relates to a hanger that suspends a ceiling plate support member assembled in a lattice shape from a ceiling wall.

  A lattice-like ceiling board support member f that supports the ceiling board p as shown in FIG. 19 is already well known (see, for example, Patent Document 1). The ceiling plate support member f includes a plurality of main bars g arranged in parallel, and a plurality of cross bars h that are arranged orthogonally between the main bars g and are respectively fixed to both side surfaces of the main bar g. It consists of and.

  More specifically, each of the main bar g and the cross bar h has a substantially inverted T-shaped longitudinal section, and has a vertical side j in the vertical direction, a wide locking ridge i at the upper end of the vertical side j, And a latching edge k projecting to both sides at the lower end of the vertical side portion j. Further, an attachment port is opened on the side surface of the main bar g, and the tip end of the cross bar h is fitted into the attachment port so as to be connected to each other in a cross shape. Then, the main bar g and the cross bar h are sequentially assembled to form a lattice-like ceiling plate support member f as a whole.

  Further, in the ceiling plate support member f, when the ceiling plate p is sequentially mounted on the upper surfaces of the locking edges k of the main bar g and the cross bar h, a large number of ceiling plates p are supported in an aligned manner. As a result, an indoor ceiling is formed.

Moreover, the above-described ceiling plate support member f is suspended in the following manner on a ceiling wall (not shown) further above the ceiling.
A hanger b as a suspension member is connected to the lower end of the bowl-shaped suspension bolt a hanging from the ceiling wall, and the holding bar provided at the lower end of the hanger b includes a main bar g or a cross bar h. Each of the locking ridges i is sandwiched. Thereby, each member will be connected to a perpendicular direction and the ceiling board support member f will be suspended with respect to a ceiling wall. Further, the hanger b is connected to the other end of a brace brace (not shown) whose one end is fixed to the ceiling wall, and even when a horizontal force such as an earthquake acts on the ceiling plate support member f, the ceiling A configuration that can suppress left and right vibrations of the plate support member f has been proposed (see, for example, Patent Document 2).

  By the way, in recent years, when constructing a ceiling system composed of the ceiling plate p, the ceiling plate support member f, the hanger b, and the like as described above, further improvement in earthquake resistance has been demanded. In order to cope with this, connection reinforcement between each member is sequentially performed. For example, at the connection location between the hanger b and the other end of the brace, a single reinforcing plate is applied separately to the connection location, and a part of the hanger b and a part of the other end of the brace are attached by tapping screws. There has been proposed a structure in which the whole plate is integrally fixed by screwing to the reinforcing plate. In such a configuration, since the connection strength is increased by the surface rigidity of the reinforcing plate, the detachment of the member can be reliably prevented. As another measure, a configuration for increasing the number of attached hangers has been proposed. In this way, by increasing the number of connection points between the main bar and the hanger, the separation of the bar and the hanger can be further prevented, and the earthquake resistance can be improved.

JP 2004-244890 A JP 2005-282005 A

  However, the configuration using the single reinforcing plate described above has a drawback that the number of parts is increased, and it is troublesome to screw the other ends of the hangers and braces with tapping screws, and the workability is poor. Moreover, the structure which increases the number of attachments of a hanger took time for attachment work, and became a factor which prevents quick construction.

  Therefore, the present invention proposes a hanger capable of eliminating the above-described drawbacks and capable of firmly suspending the ceiling plate support member from the ceiling wall as compared with the conventional art.

  In the present invention, the upper end is connected to the lower end of a bowl-shaped suspension bolt hanging from the ceiling wall, and the lower end is connected to the upper end of the main bar or the upper end of the cross bar, so that the main bar and both side surfaces of the main bar are connected. In a hanger that suspends a grid-like ceiling plate support member consisting of a cross bar connected to the ceiling wall, the metal plate is molded to form a bifurcated bifurcated outer shape. A plate-like, horizontally long main plate portion having a projecting portion for connecting a hanger bolt projecting in a direction perpendicular to the main plate surface and connected to the lower end of the hanger bolt, and the main plate portion, Projected downward in parallel at a predetermined interval, projects in a direction perpendicular to the main plate surface and is parallel to the main plate surface, and at each end, the upper end of the main bar or the upper end of the cross bar Engaging means for engaging with The main plate surface of the main plate portion is a brace mounting surface to which the other end of the hook-shaped brace having one end fixed to the ceiling wall is attached. A hanger characterized by that.

  The hanger according to the present invention has two footpads, and an engaging means is provided at the tip of each footpad. For this reason, although it is a single configuration, it will be connected at two locations simultaneously with the main bar or cross bar, and the number of connection locations will increase compared to the conventional configuration, so there is no increase in the number of parts and the main bar or cross bar. The connection can be made even more secure. Further, this hanger is obtained by molding a substantially rectangular metal single plate, the main plate portion and the footpad portion are substantially continuous along the surface direction, the main plate portion, Since it is a flat plate-like structure in which a cut portion and a bent portion are not formed, local stress concentration does not occur in the main plate portion. For this reason, this main board part will be provided with high surface rigidity, and it can prevent that hanger itself deform | transforms by shaking, such as an earthquake. In addition, since the toes of the hanger according to the present invention are arranged in parallel in the same direction at a predetermined interval from each other, the main plate portion that inevitably connects the both toes becomes a horizontally long shape, and the surface ( The main plate surface) is expanded as compared with the conventional hanger. For this reason, the advantage of the surface rigidity of the main plate portion is further amplified, and the mounting surface of the brace connected to the ceiling wall is wider than that of the conventional product, so that a sufficient mounting space can be secured. When the brace mounting surface is expanded in this way, the connection work between the hanger and the brace becomes easy, and it is also possible to fix each other using a relatively large and high strength fixing tool. Therefore, this structure can improve workability | operativity of the operation | work which attaches a various member compared with the conventional structure mentioned above, can improve connection strength, and can improve earthquake resistance. In addition, since the projecting direction of the toe portion and the protruding direction of the projecting piece for connecting the suspension bolt are the same direction with respect to the main plate portion, the lower end of the suspension bolt is used in the usage state of the hanger. The engaging means of each toe part is located substantially vertically below. In other words, by appropriately adjusting the bending state of the toe portion in the plate thickness direction, the axial direction of the suspension bolt and the center of gravity of the main bar or the cross bar are matched as much as possible, and the ceiling in the suspended state The balance of the plate support member can be kept appropriate.

  By the way, one first toe part of the two toe parts is connected to the upper end of the first cross bar connected to one side of the main bar, and the other second toe part is A configuration for connecting to the upper end of the second crossbar connected to the other side of the main bar is proposed. In such a configuration, the surface direction of the main plate portion coincides with the axial direction of both crossbars. For this reason, even if a tensile force to pull out from the main bar acts on the cross bar, the surface rigidity of the main plate portion generates a reaction force against such a tensile force to resist the tensile force. As a result, the crossbar is prevented from being pulled out and the connection is ensured. A configuration is also proposed in which the two toes are connected to the upper end of the same main bar or the upper end of the cross bar. By adopting such a configuration, the number of connection points with the main bar or the cross bar increases, so that the mutual connection becomes strong.

  Moreover, the structure by which the engaging means arrange | positioned at the front-end | tip of each toe part is a clamping tool which clamps the upper end of a main bar or the upper end of a cross bar is proposed.

  In such a configuration, since the upper end of the main bar or the cross bar is sandwiched and suspended from both sides by the sandwiching tool, the connection between the main bar or the cross bar and the hanger becomes strong.

  In addition, a configuration is proposed in which bent flange portions in which end edges are bent at right angles to the plate thickness direction are arranged on both side edges of each toe portion.

  By setting it as this structure, the intensity | strength of a toe part will improve and the intensity | strength of a hanger will also improve in connection with this.

  In addition, a configuration is proposed in which a bent flange portion whose end edge is bent at right angles to the plate thickness direction is disposed on the outer edge of the main plate portion.

  By setting it as this structure, the intensity | strength of a main-plate part will improve and the intensity | strength of a hanger will also improve in connection with this.

  In addition, a suspension member having a strip shape and having engagement means disposed at the lower end is fixed to the main plate portion, and the engagement means of the suspension member is located between the engagement means of both footpads. A configuration is proposed.

  Here, a hanger having a conventional configuration can be suitably used as the suspension member. By adopting such a configuration, there are three connection points between the main bar or cross bar and the hanger, and the connection is further ensured.

  The hanger of the present invention has a bifurcated substantially bifurcated outer shape, comprises a horizontally long and flat main plate portion, and two toe portions protruding in parallel from the main plate portion, and Since the main plate surface of the main plate part is a brace mounting surface, it is connected at the same time as the main bar or crossbar at two locations even though it is a single configuration, and the connection location is the conventional configuration without increasing the number of parts As a result, there is an effect that the safety can be further enhanced with respect to the connection with the main bar or the cross bar without impairing the workability. Further, this hanger is obtained by molding a substantially rectangular metal single plate, the main plate portion and the footpad portion are substantially continuous along the surface direction, the main plate portion, Since it is a flat plate shape in which a cut portion and a bent portion are not provided, the hanger itself is not easily deformed due to its high surface rigidity. In addition, the main plate of the hanger according to the present invention is formed in a horizontally long shape because the parallel toe portions are formed at intervals, and it is possible to secure a wider brace mounting surface than in the past. In addition to improving the connection work between the hanger and the brace, there is an effect that the connection can be further strengthened using a large fixing tool. Therefore, the present invention has an advantage that the connection strength can be improved and the earthquake resistance can be improved without deteriorating the workability of the attaching work.

  In addition, in the case of a configuration having a holding tool for holding the upper end of the main bar or the cross bar, it is possible to securely hold the upper end of the main bar or the cross bar and securely hold the hanger and The reliability of the connection with the main bar and the like is further improved, and the seismic strength of the ceiling system can be improved.

  Further, when the bent flange portions are provided on both side edges of the toes, the strength of the toes can be improved, thereby improving the mechanical characteristics of the hanger and improving the ceiling system. It has the effect of increasing seismic strength.

  In addition, when the bent flange portion is provided on the outer edge of the main plate portion, the strength of the main plate portion can be improved, thereby improving the mechanical characteristics of the hanger and improving the earthquake resistance of the ceiling system. There is an effect that can be enhanced.

  Further, the suspension member having a strip shape and having engagement means disposed at the lower end is fixed to the main plate portion, and the engagement means of the suspension member is located between the engagement means of the both toes. In this case, it is possible to further increase the number of connection points between the main bar or the cross bar and the hanger, and it is possible to easily reinforce the connection points.

Embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in FIGS. 8 and 9, the lattice-like ceiling plate support members 99 that support the ceiling plate are arranged in a plurality of orthogonal shapes between the plurality of main bars 100 and the main bars 100. The cross bar 105 is fixed to both side surfaces of each.

  Here, the main bar 100 and the cross bar 105 have a substantially inverted T-shaped vertical cross-section, and the wide locking ridges at the upper ends of the vertical side portions 102 and 107 and the vertical side portions 102 and 107 in the vertical direction. Locking edge portions 103 and 108 projecting to both sides at the lower ends of the portions 101 and 106 and the vertical side portions 102 and 107 are provided. Furthermore, an attachment port 110 (see FIG. 8) is opened on the side surface of the main bar 100, and the connection end 104 of the cross bar 105 is inserted into the attachment port 110 and connected to each other in a crossing manner. Then, the main bar 100 and the cross bar 105 are sequentially assembled to form a lattice-like ceiling plate support member 99 as a whole. And in order to suspend such a ceiling board support member 99 with respect to the ceiling wall 70, the hanger 1a-1d is used.

<First Example>
The hanger 1a according to the present invention is formed by bending or pressing a thin steel plate (metal plate) having a thickness of about 2 mm. More specifically, as shown in FIG. 1, the outer shape of the hanger 1 a is a bifurcated shape that is substantially oblong and U-shaped in a front view. It consists of two toe portions 5, 5 of the same length and the same shape protruding in parallel.

  The main plate portion 2 has a horizontal width of about 110 mm and a vertical length of about 50 mm, and has a flat plate shape. Further, the side edges (outer edges) at both the left and right ends are respectively provided with bent flange portions 30 that are bent at right angles to one side (the back side in FIG. 1) (see FIG. 2). . The bent flange portion 30 increases the strength of the main plate portion 2.

  Moreover, as shown in FIGS. 2-4, it protrudes to the one side (in FIG. 1 back side) with respect to the main plate surface (surface) of the said main plate part 2 in the upper end of the main plate part 2, and the center position. The hanging bolt connecting projection piece 8 is provided. The suspension bolt connecting projection piece 8 is formed to be orthogonal to the main plate surface of the main plate portion 2, and at the center of the protruding portion is a long hole-shaped cutout portion 10 having an open end. Is formed. In addition, the end of the tip of the suspension bolt connecting projection piece 8 is also bent downward, and a bent flange portion 11 for preventing deformation of the suspension bolt connection projection piece 8 is provided.

  Each of the toe portions 5 has a strip shape having a longitudinal length of about 50 mm and a width of about 30 mm, and protrudes along the both side ends of the main plate portion 2 in parallel downward with the same length. An interval of about 40 mm is secured between the toes 5 and 5. Further, as shown in FIGS. 2 to 4, each footpad 5 is bent in the thickness direction of the main plate portion 2 and is arranged on one side so as to be parallel to the main plate surface of the main plate portion 2 (FIG. 2). (Upward direction). Specifically, as shown in FIG. 3, each toe portion 5 is coupled to the main plate portion 2 and is inclined to the main plate portion 2 at a predetermined angle, and is coupled to the inclined portion 15. The main plate portion 2 and the parallel portion 16 extending in parallel are configured.

  In addition, the side edge of the footpad 5 is provided with a bent flange portion 31 whose end edge is bent at a right angle on one side (the back side in FIG. 1) (see FIG. 2). Such a bent flange portion 31 increases the strength of the toe portion 5.

  Further, a holding tool 7 that holds the locking ridge 101 of the main bar 100 or the locking ridge 106 of the cross bar 105 is disposed at the lower end of the parallel portion 16. The sandwiching tool 7 is composed of two members, and a first connecting piece 7a coupled to the parallel portion 16 and a separate second connecting piece 7b shown in FIG. Used. More specifically, the lower ends of both connecting pieces 7a and 7b are formed in a hook shape, and an insertion locking piece 75 having an L-shaped cross section is formed at the upper end of the second connecting piece 7b. Then, the insertion locking piece 75 is inserted into the horizontally long rectangular through hole 18 opened in the center of the toe portion 5, and the second connecting piece is engaged by engagement between the insertion locking piece 75 and the hole edge of the through hole 18. 7 b is attached to the footpad 5. Then, the tips of the connecting pieces 7a and 7b are expanded with the engaging position as a fulcrum, and the retaining screw 28 is inserted into the through-hole 27 in the plate thickness direction provided in the connecting pieces 7a and 7b. Thus, the gap between the connecting pieces 7a and 7b can be adjusted (see FIG. 7). The hook shape of the connecting pieces 7a and 7b is formed in accordance with the shape of the locking ridge 101 of the main bar 100 or the locking ridge 106 of the cross bar 105, and sandwiches the locking ridges 101 and 106. It is made into the dimension shape which engages with the outer peripheral surface of the said latching ridges 101 and 106 in the state of contact | adhering. In addition, the engaging means which concerns on this invention is comprised by the clamping tool 7 which concerns on a present Example. A known technique can be suitably employed for the holding tool 7.

  By the way, in the part where the main plate portion 2 and each footpad portion 5 are continuous, vertically long ribs 25 raised in the plate thickness direction are respectively provided. In addition, two portions of triangular ribs 26 raised in the plate thickness direction are provided at portions where the parallel portion 16 and the holding tool 7 are continuous in the toe portion 5. With this configuration, the strength of the required part is increased.

Next, a usage mode of the hanger 1a will be described.
The ceiling wall 70 is provided with a bowl-shaped suspension bolt 50, and the lower end of the suspension bolt 50 is connected to the upper end of the hanger 1a as shown in FIGS. More specifically, the lower end of the suspension bolt 50 is inserted from the side into the notch 10 of the suspension bolt connecting protrusion 8 and tightening nuts 51 disposed on the upper and lower surfaces of the suspension bolt connection protrusion 8. The hanging bolt connecting protrusion piece 8 is clamped by 52, and the hanger 1a and the hanging bolt 50 are connected.

  In the hanger 1a connected to the suspension bolt 50 as described above, the locking ridges 101 of the main bar 100 are respectively attached to the holding tools 7 at the lower ends of the both toes 5, 5 from below, 28 is tightened to clamp the locking ridge 101. Thereby, the main bar 100 and the hanger 1a will be connected. Here, such a configuration holds the locking ridges 101 at two locations with respect to the single main bar 100.

  Moreover, in this structure, since the projecting direction of the toe portion 5 and the projecting direction of the suspension bolt connecting protrusion 8 are the same direction with respect to the main plate portion 2 (see FIG. 3), the hanger 1a In the state of use, the holding tool 7 of each footpad portion 5 is positioned substantially vertically below the lower end of the suspension bolt 50. In other words, by appropriately adjusting the degree of bending of the toes 5 in the thickness direction, the axial direction of the suspension bolt 50 and the center of gravity of the main bar 100 are matched as much as possible, and the equilibrium balance in the suspended state is achieved. Can be optimized.

  Further, as shown in FIGS. 6 and 7, one side surface (front surface) of the main plate surface of the main plate portion 2 is a brace mounting surface 20, and the brace mounting surface 20 is adjacent to the suspension bolt 50. The other end of the brace 40 having one end connected to the suspension bolt 50 ′ is fixed by a tex screw 41. Note that one side surface (front surface) of the main plate portion 2 described above is a surface of the main plate surface of the main plate portion 2 that is opposite to the protruding direction of the suspension bolt connecting protruding piece portion 8.

  More specifically, the brace 40 includes a brace body 44, a wing plate bolt 47 that is attached to the upper end of the brace body 44 via a tex screw 46, and an upper brace bracket 42 that is attached to the upper end of the wing plate bolt 47. ing. Then, the upper end of the brace 40 is fixed to the ceiling wall 70 via the suspension bolt 50 'by hooking the suspension bolt 50' on the long hole-shaped notch 43 formed in the brace upper bracket 42. On the other hand, at the lower end of the brace body 44, the tex screws 41 are arranged in two places up and down and fixed to the hanger 1a. With such a fixing mode, the brace 40 is held in an inclined shape.

  By the way, since the toes 5 and 5 of the hanger 1a are provided in parallel at intervals, the main plate 2 connecting the both toes 5 inevitably has a horizontally long shape, and the main plate surface is a conventional hanger. It will be expanded compared to. In other words, when the main plate portion 2 has a horizontally long shape, the brace mounting surface 20 is expanded. As a result, the place where the other end of the brace 40 is disposed is expanded, so that the connection work of the brace 40 is facilitated, and a relatively large and high-strength fixture can be used.

  As shown in FIG. 6, the brace 40 is fixed to the left and right sides with the hanger 1a as the center, and the other ends of the two different braces 40 are fixed to the single brace mounting surface 20, respectively. It will be. As described above, even when two different braces 40 are attached, the present invention can sufficiently secure the area of the brace attachment surface 20, and thus can be securely fixed.

  Since the hanger 1a described so far has a single configuration and is connected at two locations simultaneously with the main bar 100, the number of connection locations increases as compared to the conventional configuration, and the mutual connection becomes stable. Further, the main plate portion 2 and the footpad portion 5 are substantially continuous along the surface direction, and the main plate portion 2 has a flat plate shape in which a cut portion and a bent portion are not provided. The load is easily distributed over the entire portion 2 and local stress concentration does not occur. For this reason, the main plate portion 2 has high surface rigidity, and the hanger 1a itself can be prevented from being deformed by a shake such as an earthquake.

  Of course, the above-described configuration may be a configuration in which the both footpads 5 and 5 are connected to the single cross bar 105.

<Second Example>
Another example of use is proposed.
The configuration according to the first embodiment (see FIGS. 6 and 7) is to connect the hanger 1a to a single main bar 100 or cross bar 105, but the hanger 1b according to the second embodiment includes each footpad. 5 is connected to separate crossbars 105a and 105b.

  As shown in FIGS. 8 and 9, the ceiling board support member 99 includes a main bar 100, and a first cross bar 105a and a second cross bar 105b.

  And the toe part 5 (1st toe part) and the 1st cross bar 105a which are located in the right side in FIG. 8 are connected, and the toe part 5 (2nd toe part) and the 2nd cross which are located in the left side are connected. The bar 105b is connected.

  In such a use mode, even if a tensile force for pulling out the cross bars 105a and 105b is applied, a reaction force is generated in the main plate portion 2 against the tensile force to resist the tensile force. Therefore, the connection between the cross bars 105a and 105b can be more reliably prevented from being released.

  In addition, about the connection aspect of the suspension bolt 50 and the hanger 1b, and the connection aspect of the brace 40 and the hanger 1b, since it is the same as that of the structure which concerns on a 1st Example, description is abbreviate | omitted. Further, the fixing between the crossbars 105a and 105b and the holding tool 7 is the same as the configuration according to the first embodiment, and thus the description thereof is omitted.

Reference) and a holding tool 85 disposed at the lower end of the body portion 82. Further, the body portion 82 is entirely bent in the thickness direction, and parallel portions 83 are formed in the upper half portion, and bent flange portions 87 are formed on both side edges of the body portion 82, respectively. Is formed. In addition, since the structure of the said clamping tool 85 is already well-known and is a mechanism similar to the above-mentioned clamping tool 7, description is abbreviate | omitted.

The suspension bolt 50 is inserted into the through hole 86. Then, the suspension bolt 50, the hanger 1c, and the hanger 80 are fixed by the above-described tightening nuts 51 and 52 (see FIGS. 13 and 14). With this configuration, the holding tools 7, 7, 85 are arranged in the left-right direction.

  By the way, in the state where the hanger 80 and the hanger 1c are connected, the dimension is designed so that the holding tool 85 of the hanger 80 of the conventional configuration and the holding tool 7 of the hanger 1c are at the same height position. . Moreover, in this connection state, it attaches so that the toe part 5 of the hanger 1c and the lower half part of the hanger 80 may protrude on the same side.

Specifically, the side edge of the hanger 80 is brought into contact with the center of the opposite surface of the brace mounting surface 20 on the main plate portion 2 associated with the hanger 1d, and the hanging bolt connecting projection 81 and the hanger 1d are suspended. The suspension bolt 50, the hanger 1d, and the hanger 80 are fixed in a state where the bolt connection projecting piece 8 is overlapped.
