Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a system ceiling suspension structure and a system ceiling.
[0002]
[Prior art]
Conventionally, a T-bar is assembled in a grid shape to form a grid-like base, and it is suspended from a slab or other housing. There is known a system ceiling that drops and locks installed equipment plates and the like.
[0003]
FIG. 10 is a perspective partial sectional view showing an outline of a conventional system ceiling suspension structure. FIG. 11 is an explanatory diagram showing a schematic configuration in the cross-sectional direction.
The ceiling base suspended from the housing 1 is configured by a T-bar 2 crossed at, for example, an interval of 2 feet (609.6 mm) and assembled in a grid shape. The web 2a of the T-bar 2 is directed upward, and the flange 2b is extended in the horizontal direction to serve as a receiving surface for locking a ceiling board or the like.
[0004]
There are two types of suspension methods for ceiling foundations: the suspension bolt method and the wire suspension method. The latter, which can be constructed with cheaper materials, is common in Europe and the United States. The wire suspension method is shown in FIGS. is there.
[0005]
In this case, the T bar 2 is suspended from the housing 1 by post fixing wires 24 in the vertical direction and four wire braces 22 in the oblique direction in the vicinity of the intersections where they intersect. Both wires are connected to the locking holes of the locking hardware 23 clamped to the slab surface 1b of the casing 1 by the flanges 6 on the casing side, and to the wire locking holes 2c provided near the intersection on the T bar side. , Respectively, after the wire is passed, it is twisted and locked. For this reason, the ceiling base is locked vertically and horizontally in a normal state, and supports the weight of the ceiling plate and the equipment plate from above. However, when an external force such as an earthquake is applied and the ceiling base is moved upward, an upward displacement or deformation occurs.
[0006]
Therefore, a compression post 21 that restricts deformation in the vertical direction is provided so as to surround the post fixing wire 24. Although the compression post 21 extends in the extension direction using a conduit, an off-the-shelf product having a stopper mechanism that restricts compression in the compression direction is used.
[0007]
On the other hand, a peripheral edge 20 having an L-shaped cross section is fixed to the wall surface 1a with screws 10 from the side so as to accommodate the end portion of the T bar 2 between the wall surface 1a of the housing 1 and the wall 1a. . The T-bar 2 assembled in a grid shape is locked so as to be dropped from above onto a receiving surface extending horizontally from the wall surface 1 a by the peripheral edge 20, but is not fixed, so only the wire brace 22 is horizontal. The position of the direction is regulated. In the vertical direction, it is pressed downward by the weight of the ceiling plate, equipment plate, etc., and is in contact with the receiving surface.
[0008]
The wall surface 1a is not limited to the surface of the wall extending from the floor surface. For example, in the case of a beamed ceiling, the wall surface 1a is a side surface of a beam protruding downward from the slab surface 1b.
[0009]
[Problems to be solved by the invention]
However, in the system ceiling suspension structure using the wire suspension system as described above, first, when a full-scale vibration experiment considering earthquake resistance is repeated, the wire brace 22 gradually extends and the brace becomes less effective. There was a problem. For this reason, if the number of earthquakes increases, the wire may be stretched and the earthquake resistance may be reduced. Moreover, since it is necessary to set the tension strength to an appropriate value when constructing the wire brace 22 and to suppress the variation in elongation due to the load on the ceiling plate, the labor for wire tension and the labor for confirmation become enormous, and the construction cost is reduced. There was a problem of rising.
[0010]
Moreover, in the design in Japan and the like that requires earthquake resistance compared to Europe and the United States, it is necessary to arrange a lot of relatively strong compression posts 21, and since these are equipped with expensive stopper mechanisms, the procurement cost increases. There was a problem.
[0011]
Moreover, in the surrounding edge used for said system ceiling suspension structure, since T-bar 2 was only mounted on the surrounding edge 20, there existed a problem that intensity | strength was low and it lacked earthquake resistance.
[0012]
In addition, for example, there is a great demand for a system ceiling with excellent overall workability in renovation of a building. In order to screw the peripheral edge 20 to the wall surface 1a from the side, a hole is first made in the wall surface 1a. Although it is necessary to drive the anchor to provide a screwed portion of the screw, there is a problem that the construction cost is increased and the overall cost is high.
[0013]
The present invention has been made in view of the above-mentioned problems, and while improving the strength and earthquake resistance of the ceiling foundation, it can greatly improve the efficiency of construction and can suppress the costs for manufacturing and construction. At the same time, the system ceiling suspension structure can reduce the construction cost even when the existing building is renewed. And system ceiling The purpose is to provide.
[0014]
[Means for Solving the Problems]

In the system ceiling suspension structure restricted by the brace member locked to the housing, the brace member is made of steel and the one end of the brace member is fixed to the locking hardware locked to the housing. Then, the other end is fixed to the T bar.
Therefore, it is not necessary to adjust the tension of the brace member, and both ends are fixed without loosening, so that stable vibration resistance performance can be obtained even if excitation is repeated.
[0015]

A position restricting portion to be locked is provided.
Therefore, since the deformation of the T-bar is restricted by the rigidity of the tube material, the compression column member can be made of an inexpensive material without providing an expensive stopper mechanism.
[0016]
According to a third aspect of the present invention, in the system ceiling suspending structure according to the second aspect, the compression column member includes a pipe member whose both ends are cut off and a convex portion which is locked to an end portion of the pipe member. And a connecting member provided with a clamping portion that restricts and locks the position in the upward and horizontal directions across the upper end of the intersecting T-bars.
For this reason, the tube material that restricts the upward deformation of the T-bar that requires higher rigidity is manufactured in a simple shape, and the clamping portion that requires a more complicated shape is formed as a separate member, which makes it easy to manufacture as a whole. .
[0017]
According to a fourth aspect of the present invention, in the system ceiling suspension structure according to the second or third aspect, the compression column member is formed of a square steel base material, and the brace member is formed of a shape steel, and the brace member One end portion of the steel plate is welded to a locking metal object locked to the housing, and the other end portion is fixed to the side surface of the square steel base material.
Therefore, the brace member can be attached in a state where the height of the T-bar is regulated by the compression column member, and it is not necessary to adjust the height at the time of attachment, and the attachment portion becomes flat. Since it is locked to the square steel base material, the bracing member can be easily locked.
[0018]

Therefore, it is possible to easily position the T-bar by inserting the upper end portion of the T-bar into the positioning portion, and to provide a peripheral edge that can lock the T-bar between the upper receiving surface portion and the lower receiving surface portion. Because we prepare Easy installation System ceiling suspension structure It becomes.
Further, since the peripheral edge is not fixed to the wall surface, an anchor bolt driving operation for attachment to the wall surface is not necessary. Furthermore, since the buffer member which can be compressed and deformed is provided between the wall surface and the side surface portion of the peripheral edge, the blindfold can be provided while restricting the movement of the peripheral edge in the wall surface direction.
[0019]
Claim 6 In the invention according to claim 5, in the system ceiling suspension structure according to claim 5, the positioning portion of the peripheral edge is formed by providing a notch in the shape steel.

[0023]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected to the member which is the same or it corresponds through all the drawings.
[0024]
The system ceiling suspension structure according to the present invention comprises a T-bar arranged in a grid shape to form a grid-like base, and is suspended from a slab or other housing, and the grid-like base is composed of a rock wool soundproof board or the like from above. System ceiling suspension structure that drops and locks the ceiling plate and the equipment plate on which the ceiling equipment is installed, and is structured so that the T-bar is suspended from the housing and locked, and the grid base It consists of the structure of the surrounding edge which accommodates and latches the end surface of this.
[0025]
First, a configuration in which the T bar is suspended from the housing and locked will be described. FIG. 1 is a cross-sectional view in the vicinity of an intersection of T bars showing an embodiment of the present invention.
The T-bar 2 is assembled in a grid shape as in the prior art, with the web 2a facing upward and the flange 2b extending horizontally. The flange 2b forms a square-shaped opening inside the grid, and serves as a receiving surface for locking the ceiling plate and the equipment plate. In the vicinity of the intersection of the T-bar 2, a wire locking hole 2c formed in the web 2a is provided.
[0026]
On the slab surface 1b that forms the lower surface of the housing 1, a locking metal 23 is positioned immediately above the intersection of the T-bar 2, and at a position that is a predetermined distance along the direction in which the T-bar 2 below extends. The locking metal 5 is locked by, for example, a hook 6 or the like. The locking metal 23 is a member provided with a hole for passing the post fixing wire 24 and a hole for fastening to the slab 1b on the plane of the L-shaped metal fitting, for example. It is a member provided with a hole for fastening the slab 1b on one surface of the mold.
[0027]
As shown in FIG. 2, a post 3 (compression column member) is disposed between the intersection of the T-bars 2 and the slab surface 1b immediately above the intersection of the T-bar 2 and to which the locking hardware 23 is fixed. The post 3 is a square steel base material having a square cross section such as 40 × 40 mm or 40 × 25 mm, which is conventionally used as a stud. When the longitudinal direction is set to the vertical direction, the upper end portion is cut flat in the horizontal direction, and the lower end portion is a slit 3a (position restricting portion) that can be fitted over the webs 2a of the four T-bars 2 at the intersection. ) Is provided. The positions of the slits 3a are provided such that the side surfaces forming the square shape of the square steel base material are aligned substantially parallel to the extending direction of the T-bar 2 when fitted to the web 2a. Therefore, in the state where the slits 3a are respectively fitted to the T bar 2 and the upper end is in contact with the slab surface 1b, the height of the T bar 2 from the slab surface 1b is regulated by the post 3.
[0028]
Inside the post 3, there is a locking metal 23 on the slab surface 1 b, and a post fixing wire 24 is passed through the hole to be locked, and the post fixing wire 24 is passed through the inside of the post 3 and downwards. After being extended and passing through the wire locking hole 2c, a tension is applied so that the T-bar 2 fits in the slit 3a in the vertical direction, and the post 3 is wound and locked, for example.
[0029]
As shown in FIGS. 1 and 3, a brace member 4 manufactured by cutting a shape steel such as a grooved steel is extended between the side surface of the post 3 and the locking metal 5 in a vertically oblique direction. For example, both ends thereof are fixed to the post 3 (FIG. 3) and the locking hardware 5 (FIG. 4A) by spot welding or the like. Since the post 3 is locked to the T bar 2 by the slit 3a, the T bar 2 is locked to the horizontal direction by the brace member 4 as a result. The brace member 4 is cut off horizontally at the end of the post 3 on the fixed side. For this reason, the downward protrusion is suppressed, so that it does not get in the way when the ceiling board is dropped.
[0030]
Next, the configuration of the peripheral edge according to the present invention will be described.
FIG. 5 is a perspective view showing a peripheral edge according to the present invention. FIG. 6 is a cross-sectional view showing how the T bar 2 and the housing 1 are locked.
As shown in FIGS. 5 (a) and 6 (a), most of the peripheral edge 8 used in the system ceiling suspension structure according to the present invention is formed by bending a straight line three times at right angles in the same direction. And a positioning slit 8e (positioning portion) for inserting and locking the end portion of the T-bar 2 assembled in a grid shape from the side surface, and the T-bar 2 is rectangular. The ceiling edge is surrounded by
[0031]
More specifically, the channel shape of the peripheral edge 8 includes: a lower receiving surface portion 8a extending in the horizontal direction; a side surface portion 8b extending vertically from the end portion thereof and facing the wall surface 1a of the housing 1; and the side surface portion 8b. The upper receiving surface portion 8c extends in the horizontal direction and faces the lower receiving surface portion 8a, and the shielding portion 8d extends downward from the end of the upper receiving surface portion 8c. The interval between the lower receiving surface portion 8a and the upper receiving surface portion 8c is spaced by the height from the upper end surface of the web 2a of the T-bar 2 to the lower end surface of the flange 2b.
[0032]
The shape different from the above is the entering corner portion 8g (FIG. 5B) when it is assembled into a square shape, where an L-shaped cross section composed of a lower receiving surface portion 8a and a side surface portion 8b is formed. Yes. Further, in the positioning slit 8e into which the T-bar 2 is inserted, the shielding portion 8d is cut out, and a slit shape having a width to fit the web 2a is provided. Further, the upper receiving surface portion 8c is provided with a through hole 8f for screwing the T-bar 2 at a position within the width of the positioning slit 8e.
[0033]
Further, as shown in FIG. 6A, the width in the cross-sectional direction of the lower receiving surface portion 8a and the upper receiving surface portion 8c is the manufacturing error of the length a of the T bar 2 when the T bar 2 is inserted into the peripheral edge 8. The play length for swallowing is a width that is incorporated as a margin.
[0034]
Further, the side surface portion 8b and the wall surface 1a are provided with a gap necessary for assembly. The gap covers the gap as a blindfold, and also compresses and deforms the shock absorbing material 11 (which restricts the horizontal movement of the peripheral edge 8) ( The buffer member is disposed on the side surface portion 8b by, for example, tape fastening. As the material of the cushioning material 11, any material used as a cushioning material, a cushioning material, and a sealing material can be adopted. For example, foams such as polyurethane and polyethylene, rubbers and elastomers, and foams thereof can be employed.
[0035]
Next, the system ceiling hanging construction using the present invention described above will be described.
First, the locking hardware 23 is fixed from below by the hook 6 in accordance with the hanging position and the arrangement position of the brace member 4 on the slab surface 1 b of the casing 1.
[0036]
Next, the T-bar 2 is assembled in a grid shape, and a grid-shaped substrate is assembled. Then, the end of the T bar 2 is fixed by the peripheral edge 8. At this time, since the positioning slits 8e are provided in advance on the peripheral edge 8, the T-bar 2 can be easily locked without the need for inking.
[0037]
Further, the peripheral edge 8 is locked in the horizontal direction by the positioning slit 8e in the vertical direction by the lower receiving surface portion 8a and the upper receiving surface portion 8c. ing.
[0038]
However, if it is necessary to further increase the rigidity for reasons such as earthquake resistance and construction work efficiency, the web 2a and the peripheral edge are formed with a screw 10 such as a tapping screw through the through hole 8f provided in the upper receiving surface portion 8c. 8 is screwed.
[0039]
Thus, since the peripheral edge 8 is not fixed to the wall surface 1a, it is not necessary to drive an anchor bolt or the like for fixing to the wall surface 1a, and the construction to the housing 1 is only the slab surface 1b. Therefore, the construction labor can be saved. Further, for example, even when a building is renewed, there is no need for construction that further damages the trace of the existing peripheral edge of the wall surface 1a being removed. As a result, there is an advantage that the system ceiling can be constructed at low cost even in the renewal construction.
[0040]
Next, the post fixing wire 24 is locked in the wire locking hole 2 c of the T-bar 2. Subsequently, after the post fixing wire 24 is passed through the inside of the post 3, the slit 3a is fitted from above so as to straddle the web 2a at the intersection.
[0041]
Then, the T-bar 2 is lifted, the post fixing wires 24 are locked to the locking hardware 23 to be locked, and pulled up. When the height is determined, the position is fixed by twisting the wire or the like. . At this time, since the post 3 becomes a span material between the slab surface 1b and the T-bar 2, if the post fixing wire 24 is pulled to lift the T-bar 2 without looseness from the post 3, the entire horizontal can be obtained. It is. Therefore, there is no need for adjustment and confirmation, which is very convenient.
[0042]
Next, the brace member 4 is disposed. First, a position is selected so that the plane on which the brace member 4 is fixed by welding or screws is substantially aligned with the side surface of the post 3, and the locking metal 5 is beaten on the slab surface 1 b with the scissors 6. At this time, as shown in FIG. 4B, after the hammering, the locking metal 5 can be rotated in the horizontal direction, so that the positioning of the fixed surface is easy.
[0043]
Further, since the height of the T-bar 2 has already been determined at the time of this work and the brace member 4 has only to be disposed while maintaining the height, the position of the brace member 4 may be adjusted in-situ. That is, it is possible to place the brace member 4 temporarily on the side surfaces of the hooked locking metal 5 and the post 3 and perform spot welding.
[0044]
Once the brace member 4 is fixed by welding or screws, the brace member 4 does not loosen even if it is repeatedly subjected to vibration like a wire, so that it becomes a very stable brace and improves the earthquake resistance of the system ceiling.
[0045]
Now that the installation of the ceiling base is completed, the ceiling plate and the equipment plate are dropped from above, the system ceiling is configured, and wiring work is performed behind the ceiling.
[0046]
At this time, in the present invention, as shown in FIG. 5B, the corner 8g of the peripheral edge 8 has an L-shaped cross section, and the upper receiving surface 8c and the like from the two sides is the inner side of the grid. The ceiling plate 9 can be dropped without difficulty from above, which is convenient.
[0047]
By the way, the cushioning material 11 provided on the side surface portion 8b of the peripheral edge 8 is a blindfold that fills the gap between the peripheral edge 8 and the wall surface 1a. It is convenient that there is a dimensional margin for mounting.
[0048]
Further, since the T-bar 2 is structured to be locked to the peripheral edge 8, the peripheral edge 8 also moves with the roll of the T-bar 2. Since the cushioning material 11 also exhibits the effect as a cushioning material against such rolling, damage does not occur even if it rolls. For this reason, it is also possible to use the wall surface 1a as a horizontal locking member of the T-bar 2. In this case, the brace member 4 can be deleted or reduced if the area is small, and the brace component cost can be reduced. .
[0049]
In the above description, the post 3 is described as a square steel base material. However, if the post 3 is formed into a square, the brace member 4 can be easily fixed, and the post 3 is not limited to a square. For example, the end of a pipe material such as a circular pipe may be drawn into a square shape, or the main body is manufactured with a circular pipe, and the brace member 4 is fixed to the main body only through the square steel base material. May be.
[0050]
Below, the structure and effect | action of the modification of this invention are demonstrated.
FIG. 7 shows a modification regarding the fixing of the brace member 4. In this example, the brace member 4 is fixed not to the post 3 but to the T-bar 2 by, for example, welding or screw fastening.
[0051]
If comprised in this way, since the restriction | limiting of the horizontal direction of T-bar 2 is made | formed by the brace member 4, the width direction of the slit 3a can be made into the width dimension which has a big play with the web 2a. Therefore, since the processing accuracy of the slit 3a can be relaxed, the manufacturing cost of the post 3 can be reduced.
Further, since the brace member 4 is not fixed to the post 3, there is an advantage that the post 3 can be employed without additional work such as a circular pipe other than the square steel base material.
[0052]
Next, what is shown in the exploded perspective view of FIG. 8 is a modification of the compression column member. In this example, for example, a post support metal 7 including a post body 12 made of a square steel base material having both ends cut off horizontally, and a locking portion between the T bar 2 and a locking portion between the post body 12. A compression column member is configured by connecting (connecting members). For convenience of illustration, members similar to those described above such as the post fixing wire 24 are omitted.
[0053]
As shown in FIG. 9A, the post support metal 7 includes a cross-shaped upper surface receiving portion 7b matched to the width and arrangement of the upper surface of the web 2a of the crossed T-bar 2, on which the post main body 12 is provided. A convex portion 7a that can be fitted to the inner or outer surface of the tube is provided. Side end receiving portions 7c (clamping portions) are provided that extend downward from the radially extending end portions of the upper surface receiving portion 7b and can sandwich the width of the web 2a. The side receiving portion 7c is provided with a locking claw 7d having a convex shape that is locked to, for example, a step provided on the web 2a when the web 2a is sandwiched to constitute a retaining shape.
[0054]
FIG. 9B shows a state in which the web 2a is sandwiched between the side surface receiving portions 7c of the post support metal 7 and the post main body 12 is fitted to the convex portions 7a from above and connected to each other. Since the post support metal 7 and the post 12 are compression-side regulating members, it is not necessary to fix them by welding or screw fastening.
[0055]
The post support metal 7 can be manufactured in various shapes using various materials such as metal and synthetic resin. For example, the shape illustrated in FIG. 9A is formed by punching a single steel plate and bending it appropriately. It can be easily manufactured by sheet metal working. Further, since the post support metal 7 is relatively small, it is easy to manufacture with a synthetic resin mold, and mass production is possible and it can be manufactured at low cost.
[0056]
Further, since the post main body does not need to be machined like the slit 3a provided in the post 3, the post main body 12 can be manufactured at low cost.
[0057]
Therefore, if comprised in this way, the post main body 12 which occupies most compression column members will be manufactured with a general-purpose member of a simple shape, and the post support hardware 7 which occupies a smaller part will be manufactured with another member, for example, mass production. By using a mold that can be easily manufactured, there is an advantage that the compression column member can be configured at low cost as a whole.
[0058]
In this modification, the post 12 has been described as a square steel base material. However, it is needless to say that an arbitrarily shaped tube material can be employed as long as the fitting shape of the convex portion 7a is matched.
[0059]
【The invention's effect】
As described above, in the invention described in claim 1, by using a shape steel for the brace member, tension adjustment is not necessary, both ends are fixed without loosening, and a brace that is stable even when repeated excitation is obtained. Since it can be provided, it has the effect of improving the earthquake resistance and facilitating the construction.
[0060]
In the invention according to the second aspect, since the deformation of the T-bar is restricted by the rigidity of the pipe material, the compression column member can be formed of an inexpensive material without providing an expensive stopper mechanism. The production cost can be reduced.
[0061]
In the invention according to claim 3, since the pipe material that regulates the upward deformation of the T bar that requires greater rigidity is manufactured in a simple shape, and the sandwiching portion that requires a more complicated shape is a separate member, The compression column member can be easily manufactured as a whole, and the manufacturing cost can be reduced.
[0062]
In the invention according to claim 4, the brace member can be attached in a state where the height of the T bar is regulated by the compression column member, and it is not necessary to adjust the height when attaching the brace member. Since the portion is locked to the square steel base material having a flat surface, the bracing member can be easily locked, so that the construction efficiency can be improved and the construction cost can be suppressed.
[0063]
According to the fifth aspect of the present invention, the peripheral edge that can easily position the T-bar by inserting the upper end of the T-bar into the positioning portion and can lock the T-bar between the upper receiving surface portion and the lower receiving surface portion. With So Easy installation The There is an effect that construction efficiency can be improved and construction cost can be reduced.
In addition, a cushioning member that can be compressed and deformed is provided between the wall surface and the side surface portion of the peripheral edge so that the movement of the peripheral edge in the direction of the wall surface can also be used as a blindfold, improving seismic resistance and reducing manufacturing costs. There is an effect that can be.
[0064]
In invention of Claim 6, since a surrounding edge is comprised by providing a notch in a part of cheap shape steel, there exists an effect that it can be set as an inexpensive surrounding edge.
[0067]
Claim 7 In the invention described in (4), since the system ceiling includes the system ceiling suspension structure as described above, the same effects as described above can be achieved.
