Description

  The present invention relates to a ceiling support structure at a boundary portion between a wall and a ceiling.

The foundation material for the ceiling of the building is defined in JIS A 6517 “Structural steel foundation material (wall / ceiling)”. However, the standard does not describe the structure of the boundary between the wall and ceiling in the building.
The general structure of the boundary between the wall and the ceiling is that the field edge is fitted into a groove-type runner that is installed on the wall and the opening is directed to the side. It is fixed to the field edge by screwing or the like (for example, see Patent Document 1 and Patent Document 2).
For example, FIG. 1 of Patent Document 1 and FIG. 7 of Patent Document 2 illustrate a state in which the end portion of the field edge is fitted and supported by a runner having a cross-sectional groove shape.
As another structure, in Patent Document 2, a field edge (light ceiling material) is supported by a field edge support portion (light beam receiving portion) fixed to the upper frame runner of the wall body corresponding to each field edge. A structure is proposed. In this example, a field edge support portion is formed for each field edge. In Patent Document 2, etc., the upper frame runner that is the upper frame of the base material frame of the wall body is different from the runner that is installed on the wall body and supports the field edge.

JP 2002-276068 A Japanese Patent Laid-Open No. 2006-221409

By the way, as shown in FIG. 13, in the structure in which the end of the field edge 2 is supported by the wall 1 at the boundary between the wall 1 and the ceiling, the installation height of the field edge 2 indicated by the alternate long and short dash line a is maintained. Not only to support the field edge 2 but also to fix the ceiling material 3 (shown in FIG. 14) to the field edge 2 in order to prevent the field edge 2 from moving in the height direction indicated by the arrow m ( (Vertical direction) movement and horizontal movement indicated by arrow n must be regulated. It is necessary to temporarily fix the field edge 2 to the wall side so that at least the end of the field edge 2 does not move when the ceiling material is attached.
Note that the alternate long and short dash line b is the center line along the vertical direction of the end of the field edge 2 and indicates the horizontal reference of the field edge 2.

  In order to fix the ceiling material 3 to the field edge 2, as shown in FIG. 14 (a), when the screw 4 is screwed into the field edge 2 from the lower side of the ceiling material 3, only the downward movement of the field edge 2 is performed. However, if the upward movement is not restricted, as shown in FIG. 14B, when the screw 4 is to be screwed in, the field edge 2 is pushed by the screw 4 from below and floats up. And screwing becomes difficult. Therefore, as shown in FIG. 14C, it is necessary to generate a reaction force against the force applied at the time of screwing as indicated by the white triangle.

Further, as shown in FIG. 15, if the height positions of the field edges 2 are not aligned with high accuracy, there is a possibility that unevenness will occur on the ceiling.
In addition, as shown in FIG. 16, when the side edge of the ceiling material 3 on the wall 1 side is fixed only by the field edge 2, it is a portion between the adjacent field edges 2 due to the weight of the ceiling material 3. There is a possibility that the slack indicated by the arrow c occurs in the ceiling material 3. If the ceiling material 3 is slack at the boundary between the ceiling and the wall 1, it is easier to recognize the slack than other parts of the ceiling, and even a slight bend may impair the beauty of the ceiling. Note that the amount of slack indicated by the arrow c is larger than the actual slack for easy understanding.

  With respect to the problem of the field edge at the boundary between the wall and the ceiling as described above, in the method of fitting the edge of the field edge into the grooved runner attached to the wall with the above opening facing sideways, Since the edge of the field edge is inserted and fitted into the opening of the grooved runner, the vertical and horizontal movement of the edge of the field edge is restricted. In particular, the upper piece of the grooved runner is arranged above the edge of the field edge, and the reaction force of the force applied when screwing the ceiling material can be generated by the grooved runner. It can be easily stopped.

In addition, since the groove-shaped runner is arranged over the entire width of the wall, if the runner is mounted horizontally on the wall, the height position of each field edge can be adjusted with high accuracy, preventing unevenness of the ceiling it can.
In addition, since the grooved runner is arranged over the entire width of the wall, it becomes possible to fix the side edge on the wall side of the ceiling material not only to the field edge but also to the lower piece of the runner. The loosening of the material can be surely prevented.

From the above, the functions required of the runner that supports the ceiling material 3 and the field edge 2 on the wall 1 side are the following five points.
The first function is that the field edge can be temporarily set at a predetermined position corresponding to the ceiling. That is, the edge of the field edge can be placed.
The second function is to prevent the field edge from shifting from a predetermined position.
A third function is to facilitate work with individual field height levels by using runners as a ruler for leveling each field height.
The fourth function is to have a structure in which a reaction force is generated when the ceiling material is screwed to the field edge. Accordingly, when the screw is screwed into the field edge from below through the ceiling material, the field edge is prevented from floating upward, and screwing can be facilitated.
The fifth function is to prevent the ceiling material from loosening by screwing the ceiling material to the runner at the contact portion between the wall and the ceiling.

  The first function is realized by the flange on the lower side of the grooved runner, and the second and fourth functions are realized by the state that the edge is sandwiched between the upper and lower flanges of the grooved runner. The third and fifth functions are realized by the groove-shaped runner (lower flange) extending over substantially the entire width of the wall.

The grooved runner has all the functions as described above. However, since it is necessary to install the grooved runner over the entire width of the wall, the amount of members used as the runner is large, which is costly. There is a problem that it becomes high.
In the configuration in which the field edge support portion for individually supporting the edge portion of the field edge is provided for each field edge arranged in the upper frame runner of the wall body of Patent Document 2, the cross-sectional groove-shaped runner for supporting the field edge is used as the wall body. In contrast to the general technique of arranging the entire length of the rim, the weight of the member that supports the edge of the field edge is reduced, and thus the cost can be reduced.

However, since the field edge support portions are individually installed and fixed at the marked positions, if the construction accuracy is not very good, the heights of the field edges are not aligned and there is a risk of unevenness. That is, there is no third function described above.
In addition, in the structure in which the field edge is supported by the individual field edge support portions, there is no runner over the entire width of the wall as described above, so that the ceiling material is supported only by the field edge portion at the boundary between the wall and the ceiling. Therefore, there is a risk that the ceiling material may be slack as described above. That is, there is no fifth function described above.

  The present invention has been made in view of the above circumstances, restricts the movement of the field edge when attaching the ceiling material to the field edge, and prevents the ceiling material from becoming uneven due to an error in the installation position of the edge of the field edge. In addition, it is possible to prevent the slack of the ceiling material at the boundary between the wall and the ceiling, and further, it is possible to reduce the use weight of the member that is provided on the wall and supports the field edge, thereby reducing the cost. An object is to provide a ceiling support structure.

In order to solve the above problems, the ceiling support structure according to claim 1 is a ceiling support structure that supports the ceiling at a boundary between the ceiling and the wall,

The covering portion includes a horizontal rectangular top plate and left and right rectangular side plates, the top plate and the side plate are equal in length in the length direction of the field edge, and the leading edge is aligned. It is characterized by.

In the first aspect of the present invention, since the runner is not L-shaped in cross section, but L-shaped in cross section, it is possible to reduce the use weight of the member that becomes the runner.
In addition, since the end of the field edge is not placed between the groove-shaped runners but is placed on the extended piece of the L-shaped runner, in this state, when attaching the ceiling material to the field edge In addition, there is a possibility that the field edge will rise or shift to the left or right.

Therefore, by providing a field edge fixing member for restricting the movement of the field edge with respect to the runner at each end of the field edge, and by regulating the movement of the field edge, the ceiling material can be easily fixed to the field edge, Edge shift can be prevented.
In addition, since the field edge fixing member is provided at each end of the field edge, even if the field edge fixing member is provided, the use weight of the member does not increase greatly, compared to the case where the grooved runner is used. The usage amount of the member can be suppressed, and the cost can be reduced based on the usage amount of the member.

  In addition, the field edge is mounted on and supported by the runner, so that the vertical position is determined by the runner, and it is possible to prevent the ceiling from becoming uneven due to an error in the installation position of the field edge. Can do.

Moreover, it is possible to fix the ceiling material not only to the field edge but also to the extended piece of the runner, and by attaching the ceiling material to both the runner and the field edge, the ceiling material at the boundary between the ceiling and the wall Can be prevented.
Further, the covering portion of the field edge fixing member is placed on the edge portion of the field edge placed on the runner from above and comes into contact with the left and right side surfaces and the upper surface of the field edge end portion, and the fixing portion is fixed to the runner. Therefore, even when an attachment load is applied when attaching the ceiling material to the field edge, the reaction force can be taken from the covering portion to suppress the movement of the field edge.
Furthermore, when the ceiling material is attached to both the field edge and the runner, the runner and the field edge are connected via the ceiling material, so the ceiling material is attached to both the field edge and the runner. Even if the flange of the field edge fixing member is detached from the runner, there is no problem. Therefore, it is not necessary to make the joining of the fixed portion and the runner excellent in durability, and it is possible to reduce labor and cost for joining.

In the invention of claim 2, since the fixing portion is fixed to the extended piece on the lower side of the runner, when the ceiling material is screwed to the field edge, an upward force is applied to the field edge. Further, a force is applied perpendicularly to the joint surface between the fixed portion and the extension piece, and a reaction force is easily obtained. Therefore, it is possible to use an easier method in which the joining force is not so strong for joining the fixing portion and the extending piece, and joining with the above-described adhesive or double-sided tape is easy to employ. Therefore, the use of the field edge fixing member is more likely to be easier than the case of using the field edge fixing member in claim 1.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the ceiling support structure according to this embodiment is a ceiling support structure at the boundary between the wall 1 and the ceiling (ceiling material 3), and the end of the field edge 2 is fixed to the wall 1. The runner 11 having an L-shaped cross section and a field edge fixing member 21 that fixes the field edge 2 to the runner 11 are supported.

  As shown in FIGS. 1 and 2, the runner 11 extends horizontally from the wall surface of the wall 1, extends along the width direction of the wall surface, and a base end of the extended piece 12. It is formed in a L-shaped cross section from a fixed piece 13 that is provided at a right angle to the extending piece 12 and fixed to the wall surface. The runner 11 is made of, for example, L-shaped steel. The material of the runner 11 is not limited to steel (ordinary steel), and high strength steel may be used as necessary, stainless steel may be used, or an aluminum alloy may be used. You may make it use.

The runner 11 is fixed to a predetermined height position of the wall surface of the wall 1 by, for example, screwing or the like in a state where the runner 11 is horizontally disposed.
The runner 11 supports the field edge 2 by placing the end of the field edge 2 on the extended piece 12 of the runner 11 fixed to the wall surface.

As shown in FIGS. 1 and 3, the field edge fixing member 21 regulates the horizontal and vertical movements of the end of the field edge 2 placed on the extended piece 12 of the runner 11. .
The field edge fixing member 21 includes a covering part 22 having a substantially U-shaped cross section that contacts the left and right side surfaces and the upper surface of the edge part of the field edge 2, and a fixing part 23 extending from the covering part 22 and fixed to the runner 11. It has.

The covering portion 22 of the field edge fixing member 21 includes a horizontal top plate 24 and left and right side plates 25, and has a U-shaped cross section as described above.
In this embodiment, the field edge 2 is made of a general square steel pipe or a grooved steel (a grooved steel with a lip). This field edge 2 is provided with the upper surface which is a horizontal plane in the state arrange | positioned on the ceiling, and the left and right side surfaces which are planes along a perpendicular direction.

Therefore, the upper surface of the end portion of the field edge 2 abuts the lower surface of the top plate 24 of the covering portion 22, and the inner surfaces facing each other of the left and right side plates 25 of the covering portion respectively contact the left and right side surfaces of the end portion of the field edge 2. It comes to touch.
Further, the covering portion 22 is in a state where the front and rear and the lower portion are open, and when attached to the end portion of the field edge 2, it is attached so as to cover the field edge 2 from the upper side of the field edge 2. Yes.

The fixing portion 23 is formed to extend outward at right angles from the front side edge portions of the covering portion 22 on the left and right side plates 25 (the side that contacts the fixing piece 13 of the runner 11 when fixed to the runner 11). Has been. That is, two fixing portions 23 are provided so as to form a pair of left and right.
The front surface joined to the fixing piece 13 of the runner 11 of the left and right fixing portions 23 is disposed in the same plane.
Further, the field edge fixing member 21 is manufactured, for example, by forming a thin steel plate by pressing or the like.

  In such a field edge fixing member 21, the runner 11 is fixed to the wall surface, and the covering portion 22 covers the field edge 2 with the end of the field edge 2 placed on the extended piece of the runner 11. The lower surface of the top plate 24 is brought into contact with the upper surface of the field edge 2, and the inner side surfaces of the left and right side plates 25 are brought into contact with the left and right side surfaces of the field edge 2. The front surfaces of the left and right fixing portions 23 are brought into contact with the fixing pieces 13 of the runner 11, and the fixing portions 23 are attached to the fixing pieces 13 with screws 26.

Thus, the end of the field edge 2 is fixed to the upper end of the wall surface of the wall 1 by the runner 11 having an L-shaped cross section and the field edge fixing member 21.
The ceiling material 3 is fixed to the field edge 2 with screws 31 screwed from the lower side of the ceiling material 3 in a state where the upper surface is in contact with the lower surface of the field edge 2 from the lower side of the field edge 2.

  Further, the side edge of the ceiling material 3 on the wall 1 side is brought into contact with the lower surface of the extended piece 12 of the runner 11 and is screwed with a screw 31 from below. The extended piece 12 of the runner 11 and the ceiling material 3 are screwed at a plurality of locations.

Next, a method for attaching the ceiling material at the boundary between the wall 1 and the ceiling will be described.
In addition, although the drawing referred to in the explanation of the construction procedure as the following mounting method and the explanation takes up the boundary between the wall and the ceiling that is on one end side of the field edge, in practice, the field edge and ceiling The both sides of the wall 2 are attached to the edge 2 in parallel.
First, as shown in FIG. 4, ink is drawn out at the installation position of the runner 11 on the wall surface of the wall 1 to draw a horizontal straight ink 5. The black line 5 corresponding to the straight line corresponds to, for example, the lower end of the runner 11. When the runner 11 is positioned, the lower end of the runner 11 is aligned with the black 5 position.

  As shown in FIG. 5, with the runner 11 positioned on the wall surface, the runner 11 is screwed to the wall surface using screws 14. At this time, the outer surface of the fixed piece 13 of the runner 11, which is L-shaped steel, is brought into close contact with the wall, aligned with the black 5, and the extended piece 12 is in a horizontal state, and a plurality of places of the fixed piece 13 are placed. The runner 11 is fixed to the wall. At this time, the runner 11 is screwed at a position where the base material of the wall is located. In addition, when the position of the upper frame runner of the base material frame of the wall 1 and the runner 11 overlap, the runner 11 may be fixed to the upper frame runner of the base material frame of the wall 1.

  In general, before attaching the ceiling material 3, a suspension bolt is attached to a beam or the like on the floor above the ceiling of the building, and a field receiver is provided on the lower end side of the suspension bolt. The suspension bolt and the field edge receiver are provided at preset positions, and both ends are supported by the wall 1 and support the part between the walls 1 of the field edge 2.

Next, as shown in FIG. 6, the end of the field edge 2 is placed on the extended piece 12 of the runner 11.
In this case, both end portions of the field edge 2 are placed on the runner 11 in a state where the runner 11 has already been attached on both the above-mentioned wall sides.

  Next, as shown in FIG. 7, a field edge fixing member 21 is placed on the end of the field edge 2 from above. As a result, the inner surface of the covering portion 22 is in contact with the outer surface except the lower surface of the field edge 2 as described above. In this state, the fixing portion 23 of the field edge fixing member 21 is brought into contact with the fixing piece 13 of the runner 11, and the fixing portion 23 is attached to the fixing piece 13 with a screw 26.

Thereby, as shown in FIG. 1, the end of the field edge 2 is fixed to the wall 1 via the runner 11 and the field edge fixing member 21.
Next, the field edge 2 is attached to the field edge support supported by the above-described suspension bolt. Further, when the ceiling surface is wide, the length of the suspension bolt is adjusted so that the base of the ceiling such as the field edge receiver or the field edge 2 is slightly convex upward. As a result, the ceiling surface is slightly raised upward. This is called peeling, and if the ceiling surface is provided horizontally in a large room, the center portion of the ceiling surface is prevented from appearing to be lowered.
Next, the ceiling material 3 is fixed to the extended edge 12 of the runner 11 fixed to the field edge 2 and the wall surface by, for example, screws 31.

  In this ceiling support structure, each field edge is supported by the extending piece that extends from the wall surface of the runner 11 that has an L-shaped cross section and is disposed over the entire width of the wall surface. The position can be adjusted with high accuracy. Therefore, it is possible to prevent unevenness from occurring on the ceiling due to a shift in the height position of the field edge. Moreover, the edge part of the field edge 2 is fixed by the runner 11 and the field edge fixing member 21, and the movement of the edge part of the field edge 2 is controlled when the ceiling material 3 is attached. Therefore, it is possible to prevent the field edge from moving when the ceiling material 3 is attached, making it difficult to attach the ceiling material 3, and the field edge 2 from being displaced.

  Further, since the ceiling material 3 can be fixed not only to the field edge 2 but also to the extended piece 12 of the runner 11 along the wall surface, at the boundary between the wall and the ceiling, between the field edges 2. Thus, it is possible to prevent the ceiling material 3 from loosening. From the above, in the ceiling support structure of this embodiment, the five functions required for the above-described runner can be realized by the runner 11 and the field edge fixing member 21. That is, the runner 11 enables the temporary placement of the end of the field edge 2, the third function for adjusting the height level of each field edge 2, and the side edge of the ceiling material 3 on the wall side And a fifth function for preventing slackening of the image. Further, the field edge fixing member 21 generates a second function for preventing the position displacement of the field edge and a reaction force of the force acting on the field edge 2 when the ceiling material 3 is screwed to the field edge 2. The fifth function can be realized.

  Thus, in the structure which can support a ceiling without a problem in the boundary part of a wall and a ceiling, the use weight of the member used for the runner 11 by making a runner into L shape (L shape) instead of the conventional groove shape. Can be reduced. Further, in addition to the runner 11, a field edge fixing member 21 is required corresponding to each field edge 2, but a grooved runner is used even if the use weight of the field edge fixing member 21 is added. Compared with the case where it does, the use weight of a member can be reduced and cost reduction can be aimed at.

  In the above-described embodiment, the fixing portion 23 of the field edge fixing member 21 is screwed to the fixing piece 13 of the runner 11. However, when the fixing portion 23 is attached to the runner 11, as shown in FIG. An adhesive is applied to the side surface of the runner 11 on the fixed piece 13 side of the fixed portion 23 or a double-sided tape is applied, and the side surface of the fixed portion 23 is used as an adhesive surface 28, and this adhesive surface 28 is bonded to the fixed piece 13 You may do it.

  This is because, when the field edge 2 is fixed by the field edge fixing member 21, the edge of the field edge 2 is fixed, and then the ceiling material 3 is fixed to the field edge 2 by screwing or the like. This is because it is only necessary to be able to secure a reaction force in which 2 does not deviate. If the above reaction force can be sufficiently secured by fixing with an adhesive or a double-sided tape, the construction can be facilitated by using an adhesive or double-sided tape as compared with screwing.

Next, a field edge fixing member 41 which is a modification of the field edge fixing member 21 will be described.
As shown in FIG. 9, the field edge fixing member 41 has a substantially hat shape and includes a covering portion 42 and a fixing portion 43. The covering portion 42 has the same shape as the covering portion 22 of the above-described field edge fixing member 21 and is formed from a top plate 44 and left and right side plates 45 in a U-shaped cross section.

  Like the field edge fixing member 21, two fixing parts 43 are provided on the left and right sides, but the connection position with respect to the covering part 42 is different from that of the field edge fixing member 21. In the field edge fixing member 21, the fixing portion 23 is provided vertically on the front edge portions of the left and right side plates 25 of the covering portion 22, whereas in the field edge fixing member 41, the left and right side plates of the covering portion 42 are provided. A fixed portion 43 is horizontally attached to the lower edge portion of 45.

  The fixing portion 43 of the field edge fixing member 41 is fixed to the upper surface of the extended piece 12 of the runner 11. In the field edge fixing member 41 of this modification, higher accuracy than the field edge fixing member 21 is required for the length from the upper end of the covering portion 42 to the fixing portion 43.

  However, in this field edge fixing member 41, the fixing portion 43 is fixed to the extended piece 12 on the lower side of the runner 11, so that when the ceiling material 3 is screwed to the field edge 2, When a facing force is applied, a force is applied perpendicularly to the joint surface between the fixed portion 43 and the extending piece 12, and a reaction force is easily obtained. Therefore, it is possible to use an easier method in which the joining force is not so strong for joining the fixing portion 43 and the extending piece 12, and joining with the above-described adhesive or double-sided tape is easy to employ. Therefore, the use of the field edge fixing member 41 is more likely to be easier than the case of using the field edge fixing member 21 described above.

Next, a field edge fixing member 51 which is a modification of the field edge fixing member 41 will be described.
As shown in FIGS. 10 to 12, the field edge fixing member 51 has a substantially hat shape like the field edge fixing member 41, and includes a covering portion 52 and a fixing portion 53. The covering portion 52 has the same shape as the covering portion 22 of the above-described field edge fixing member 21, and is formed in a U-shaped cross section from the top plate 54 and the left and right side plates 55.

The fixing portion 53 is horizontally arranged in a shape connected to the lower edge of the side plate 55 of the covering portion 52.
The difference between the field edge fixing member 51 and the field edge fixing member 41 is that a claw portion 56 that is hooked (engaged) with the extending piece 12 of the runner 11 is provided at the fixing portion 53 of the field edge fixing member 51. It is a point.
The fixed portion 53 is provided with a substantially rectangular claw portion 56 at the center thereof. The claw portion 56 is cut from the fixing portion 53 to the front edge portion and the left and right side edge portions of the claw portion 56 in a substantially U shape, and the claw portion 56 is clawed with respect to the remaining portion (the portion other than the claw portion). The rear edge portion of the claw portion 56 is bent so that the portion 56 moves outward in a substantially parallel state.

The extending piece 12 can be sandwiched between the claw portion 56 of the fixed portion 53 and the main body (portion other than the claw portion 56) of the fixed portion 53. Thereby, it is possible to prevent the field edge fixing member 51 from moving with respect to the runner 11.
The method of fixing the field edge 2 to the runner 11 using the field edge fixing member 51 is the extension piece 12 of the field edge 2 with the end of the field edge 2 placed on the extension piece 12 of the runner 11. The covering portion 52 of the field edge fixing member 51 is put on the center side from the portion placed on the top.

Next, the field edge fixing member 51 placed over the field edge 2 is slid toward the end of the field edge 2. At this time, the extending piece 12 is sandwiched between the claw portion 56 and the fixing portion 53. As a result, the field edge fixing member 51 is restricted from moving upward with respect to the runner 11, and the vertical movement of the field edge 2 is restricted. In addition, since the extended piece 12 is sandwiched between the claw portion 56 and the fixing portion 53, the horizontal movement of the field edge fixing member 51 with respect to the runner 11 is also suppressed.
