Description

  The present invention relates to a mounting structure for a ceiling sheet material in a building.

  Conventionally, in school gymnasiums, classrooms, concert hall facilities, etc., it has been practiced to attach a ceiling sheet material below an existing ceiling to form a designable membrane ceiling. Membrane ceilings are difficult to fall off, and since they are lightweight even if they fall on a scale, the danger is low.In recent years, instead of conventional ceilings using plaster or the like, membrane ceilings have been installed on top of conventional ceiling surfaces. There is also an example of construction. There is also an advantage that when a ceiling (structure) above the membrane ceiling falls, it can be received.

  The ceiling sheet material for forming such a membrane ceiling is attached by fixing the periphery of the ceiling sheet material to the edge around the ceiling.

  Patent Document 1 discloses a ceiling sheet in which a locking member is attached to the periphery of the ceiling sheet material, and the ceiling sheet material is stretched so that the locking member is hooked on a locking portion provided at an edge around the ceiling. The material mounting structure is described.

  According to this attachment structure, if the locking member is attached in advance to the ceiling sheet material that has been cut into the correct dimensions, the on-site attachment operation can be performed quickly.

JP 2007-10031 A

  However, since the ceiling sheet material with such a locking member has the locking member attached to the periphery, the dimensions of the ceiling sheet material cannot be changed with the locking member attached. That is, when a ceiling sheet material having a dimensional error is brought in, when a specification change occurs on the site, or when fine adjustment is necessary on the site, the size of the ceiling sheet material cannot be adjusted.

  The present invention has been proposed in view of such circumstances, and an object of the present invention is to provide a ceiling sheet material mounting structure that can be freely adjusted in size and can be easily and quickly mounted on site. It is in.

To achieve the above object, the ceiling sheet material mounting structure according to claim 1 includes a clip body and a cover clip, and the ceiling sheet material is sandwiched and fixed by the clip body. The clip body is provided with an upright substrate portion and upper and lower elastic clamping portions extending from the upper and lower ends of the upright substrate portion, while the cover clip is immersed inside The upper and lower elastic sandwiched portions of the clip body are sandwiched so as to cover the upper and lower elastic sandwiched portions from above and below. The clip body has a structure in which the upper and lower elastic clamping portions are pressed and clamped from above and below by the upper and lower clamping pieces against the generated force, and the ceiling sheet material is clamped and fixed by bringing the upper and lower elastic clamping portions close to each other. On the outer surface of the upright board part, While projections towards the bottom of the over the clip is formed on an inner bottom portion of the cover clip, wherein the recess for the projection and fitted.

  The ceiling sheet material mounting structure according to claim 2, wherein the upper and lower elastic sandwiching portions extend from the upper and lower ends of the upright substrate portion so as to expand, and the tip of the sandwiching piece is connected to the upright substrate. It is comprised from the up-and-down press nail | claw piece formed by facing the direction of the part at an acute angle and opposingly forming.

  The mounting structure of the ceiling sheet material according to claim 3 is characterized in that the distance from the upright substrate portion of the tip portion of the vertical pressing claw piece is different from each other.

  The mounting structure for the ceiling sheet material according to claim 4 is characterized in that at least one of the upper and lower pressing claw pieces has a pressing projection for pressing the other pressing claw piece.

The attachment structure of the ceiling sheet material according to claim 5 is that the top and bottom clamping pieces of the cover clip are bent to the opening side, while the vertical elastic clamping part of the clip body is constricted at the center. Features.

According to the ceiling sheet material mounting structure according to claim 1, the cover clip has the upper and lower elastic clamping portions with the upper and lower clamping pieces against the elastic force of the upper and lower elastic clamping portions of the internal clip body. Since it is configured to be pressed and clamped from above and below, the clip body can be fixed and held with the ceiling sheet material sandwiched, and the ceiling sheet material can be firmly stretched and held.
Furthermore, according to the mounting structure of the ceiling sheet material according to claim 1, the projection formed on the upright substrate portion of the clip body and the recess formed on the inner bottom portion of the cover clip are fitted. Therefore, the wobbling in the cover clip of the clip body can be prevented. Moreover, if the recessed part of a cover clip is comprised with a through-hole, a clip main body can be extruded by inserting an instrument from the through-hole.

  Since the ceiling sheet material can be stretched while operating the clip body and the cover clip in this way, the ceiling sheet material can be easily and quickly attached. Moreover, since the clamping site | part of a ceiling sheet material can be changed variously on the site, a dimension adjustment can also be performed on a construction site.

  According to the mounting structure of the ceiling sheet material according to claim 2, since the elastic pinching portion is composed of two pieces of the pinching piece and the pressing claw piece, the ceiling sheet material is firmly locked by the pressing claw. The ceiling sheet material can be strongly sandwiched with the sandwiching pieces, so that there is almost no risk of falling. Further, since the ceiling sheet material is firmly locked by the pressing claw piece, it does not move after being sandwiched.

  According to the ceiling sheet material mounting structure according to claim 3, since the distances from the upright substrate portion of the tip portion of the vertical pressing claw piece are different from each other, the tip portions of the vertical pressing claw piece may overlap each other. In addition, it is possible to prevent the ceiling sheet material from being damaged by the nails at the tips. Moreover, since the position of the front-end | tip part is varied, the ceiling sheet | seat material can be fixed to a bending state, and it can contribute to prevention of falling-off.

  According to the mounting structure of the ceiling sheet material according to claim 4, since at least one surface of the pressing claw piece is formed with a pressing convex portion that presses the other pressing claw piece, it is difficult to remove the ceiling sheet material. be able to.

According to the ceiling sheet material mounting structure according to claim 5, the top and bottom clamping pieces of the cover clip are bent at the opening side while the vertical elastic clamping portion of the clip body is constricted at the center.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1 to 5 are explanatory views of a ceiling sheet material mounting structure (a sheet mounting tool including a clip body and a cover clip) according to an embodiment of the present invention.

  The seat fixture 10 is a fixture that is installed by attaching the ceiling sheet material 1 disposed on the ceiling 2 (see FIG. 5B), and includes a clip body 20 and a cover clip 30 that houses the clip body 20. It is made up of.

  The clip main body 20 has a structure that can be projected and retracted with respect to the cover clip 30 while being elastically deformed.

  The clip main body 20 includes an upright substrate portion 21 and upper and lower elastic pinching portions 22 and 22 that are bundled in the middle from the upper and lower ends and extended at the tip.

  That is, the clip main body 20 is formed as a concave groove body that is constricted between the pair of elastic sandwiching portions 22 and 22 and expands toward the tip.

  Each elastic clamping part 22 is bent so that the clamping piece 22 a having the constricted part 22 b and the clamping operation piece 22 aa located on the distal end side of the clamping piece 22 a are folded back toward the upright substrate part 21. The pressing claw piece 22c extends.

  The pressing claw piece 22c is bent so as to be substantially parallel to the clamping operation piece 22aa located on the distal end side of the clamping piece 22a, and extends to a substantially intermediate position of the clamping operation piece 22aa. A slit-shaped opening 23 is formed between the front end of the second claw piece 22c and the front end of the other pressing claw piece 22c. The ceiling sheet material 1 can be taken in and out of the opening 23.

  As will be described later, when the clip main body 20 protrudes from the opening 33 of the cover clip 30, the clip main body 20 has no elastic force and the upper and lower clamping operation pieces 22aa and 22aa are in an open state. The C-shaped part formed by the landing action pieces 22aa and 22aa and the upper and lower pressing claw pieces 22c and 22c constitutes the receiving part 24 of the ceiling sheet material 1 inserted from the opening part 23.

  In the present embodiment, the upper and lower pressing claw pieces 22c and 22c are configured such that their lengths are different from each other and the tip positions thereof are shifted.

  In addition, two protrusions 21 a and 21 a are formed along the longitudinal direction at the center position in the height direction outside the upright substrate portion 21.

  On the other hand, the cover clip 30 is formed as a concave groove body that opens in the same direction as the opening 23 of the clip main body 20, and the opening 33 of the cover clip 30 is slightly narrower than the bottom 31. The wall portion of the recessed groove body constitutes the holding pieces 32, 32, and is configured to press and hold the internally mounted clip body 20 from above and below.

  Ribs 31c and 31c projecting slightly outward are formed at the upper and lower ends of the bottom portion 31, and two through holes 31a and 31a are formed at the center in the height direction of the bottom portion 31 along the longitudinal direction. . In addition, semicircular cutout openings 31b and 31b are formed at both ends of the bottom 31 in the longitudinal direction.

  Further, since the tips of the upper and lower clamping pieces 32 and 32 are both bent toward the opening 33, the tips of the upper and lower clamping pieces 32 and 32 of the cover clip 30 are in the clip main body 20 even when the clip main body 20 is in a protruding state. It is possible to prevent the entire clip body 20 from coming off.

  The seat fixture 10 is used in a state where the clip body 20 is housed in the cover clip 30, and as shown in FIGS. 1A and 1B, a protrusion from the opening 33 of the cover clip 30 of the clip body 20, The cover clip 30 can be freely immersed in the interior.

  The clip main body 20 is flattened by pressing the clamping operation pieces 22aa, 22aa having an elastic shape at the front of the constricted portions 22b, 22b from above and below, with the clamping pieces 22a, 22a having elasticity. When it is in a protruding state from the opening 33 of the cover clip 30, it is in an open state where no elastic biasing force acts. Further, when the clip body 20 is in the immersive state, the sandwiching pieces 22a, 22a, in particular, the sandwiching operation pieces 22aa, 22aa are elastically deformed and become a flat state in which a resilient force is applied from the inside of the cover clip 30. Yes.

  That is, the cover clip 30 has the upper and lower clamping pieces 32 a and 32 with a strong elastic force against the elastic force of the upper and lower clamping pieces 22 a and 22 a of the internally mounted clip body 20. 22aa is pressed and clamped from above and below, and the upper and lower clamping operation pieces 22aa and 22aa act so as to maintain the proximity state.

  Further, since the opening width of the cover clip 30 is larger than the width dimension of the constricted portions 22b and 22b of the clip body 20 and smaller than the height dimension of the upright substrate portion 21, the clip body 20 is in a protruding state. Sometimes, the clamping operation pieces 22aa, 22aa and the pressing claw pieces 22c, 22c in front of the constricted portions 22b, 22b protrude to the outside, but the base pieces 22ab, 22ab rearward of the constricted portions 22b, 22b The substrate unit 21 does not jump out.

  In this way, the bent tips of the upper and lower clamping pieces 32, 32 of the cover clip 30 can be locked to the constricted portions 22 b, 22 b of the upper and lower elastic clamping portions 22, 22 of the clip body 20. Therefore, it is possible to prevent the entire clip body 20 from coming off.

  Note that the clip body 20 may be attached to the cover clip 30 by sliding from the end in the longitudinal direction.

  When the clip main body 20 is in the protruding state, the ceiling sheet material 1 is inserted into the inside through the opening 23 formed between the upper and lower pressing claw pieces 22c and 22c. In this state, the upper and lower pressing claw pieces 22 c and 22 c are opened to form a C-shaped receiving portion 24, and this receiving portion 24 acts as a guide portion for inserting the ceiling sheet material 1.

  When the clip body 20 is pushed into the cover clip 30 from the front, the clip body 20 shifts from the protruding state to the immersive state. At that time, the upper and lower clamping operation pieces 22aa and 22aa and the upper and lower pressing claw pieces 22c and 22c are close to each other between the upper and lower sides, and in particular, the leading end portions of the upper and lower pressing claw pieces 22c and 22c are in elastic contact with the ceiling sheet material 1 being sandwiched. It becomes. Thus, the ceiling sheet material 1 can be strongly clamped by immersing the ceiling sheet material 1 in a state of being sandwiched between the upper and lower pressing claw pieces 22c and 22c (see FIG. 4).

  When the clip main body 20 is completely immersed in the cover clip 30, the protrusions 21 a and 21 a formed on the outer surface of the upright substrate portion 21 of the clip main body 20 are formed in the through holes 31 a formed in the bottom 31 of the cover clip 30. , 31a. Thus, since the protrusions 21a and 21a are fitted in the through holes 31a and 31a, the wobbling of the clip body 20 can be prevented. In addition, you may provide the non-penetrating recessed part of the grade which the protrusions 21a and 21a of the clip main body 20 do not slip instead of the through-holes 31a and 31a.

  Moreover, what is necessary is just to make the clip main body 20 a protrusion state, when removing the ceiling sheet material 1 from the sheet | seat fixture 10. FIG. For example, the clip body 20 is pressed and pushed out from the bottom 31 of the cover clip 30 through a through hole 31a or a notch opening 31b with an instrument such as radio pliers, or the clip body 20 is pinched with an instrument such as radio pliers from the notch opening 31b. The clip body 20 can be easily taken out by pulling it sideways.

  According to such a mounting structure of the ceiling sheet material 1, the cover clip 30 is formed by the upper and lower clamping pieces 32, 32 against the elastic force of the upper and lower elastic clamping portions 22, 22 of the internally mounted clip body 20. Since the upper and lower elastic clamping portions 22 and 22 are configured to be pressed and clamped from above and below, the clip body 20 can be fixed and held with the ceiling sheet material 1 being clamped. By fixing to the ceiling 2, the ceiling sheet material 1 can be firmly stretched and held.

  Since the ceiling sheet material 1 can be stretched while operating the clip body 20 and the cover clip 30 in this manner, the ceiling sheet material 1 can be easily and quickly attached. In addition, since the sandwiched portion of the ceiling sheet material 1 can be variously changed at the site, it is not necessary to cut the ceiling sheet material 1 into dimensions accurately in advance, and the dimensions can be adjusted at the construction site. Even when the ceiling sheet material 1 is long, it can be clamped to the seat fixture 10 in a folded state.

  As shown in FIG. 5, the sheet fixture 10 sandwiching the ceiling sheet material 1 as described above is fixed to the fixture fixing portion 40 provided at the edge of the ceiling 2 or the edge around the ceiling.

  The fixture fixing portion 40 is a rod-like body that is fixed along the edge of the ceiling 2, and is provided with an attachment piece portion 41 that is fixed to the ceiling with a fixture such as a bolt or a screw, and below the attachment piece portion 41. It is comprised from the fixed piece part 42 extended in L shape.

  On the upper surface of the horizontal piece 42a of the fixed piece part 42, an uneven part 42aa in which a concave part and a convex part continue along the longitudinal direction is formed. Further, the vertical piece 42 b of the fixed piece portion 42 is slightly smaller in height than the width of the seat fixture 10.

  As shown in FIG. 5 (b), one rib 31c of the cover clip 30 of the seat fixture 10 is fitted into the concave portion of the concave and convex portion 42aa of the horizontal piece 42a, and the sandwiching piece 32 positioned diagonally with the rib 31c. By bringing the front end into contact with the lower surface of the attachment piece 41 and inclining the sheet attachment 10 toward the vertical piece 42b, the sheet attachment 10 can be fixed so as not to come out.

  Next, various examples of the seat fixture 10 will be described with reference to FIGS.

  FIG. 6 is an explanatory view showing an example of the shape of the pressing claw piece 22c. FIGS. 6B to 6E show the pressing claw pieces 22c and 22c at the portions indicated by the one-dot chain line in FIG. An example of the sandwiched shape is shown in an enlarged view.

  In all of these four examples, the upper pressing claw piece 22c is formed longer than the lower pressing claw piece 22c, so that the ceiling sheet material 1 can be sandwiched in a folded state, and the ceiling sheet material 1 can be removed. Detachment can be prevented.

  6 (b) is configured to press the surface of the other pressing claw piece 22c with the tip of one pressing claw piece 22c. Since it is not the structure which presses between front-end | tips, damage to the ceiling sheet material 1 can be prevented.

  In FIG. 6C, the top and bottom pressing claw pieces 22c and 22c are bent so that the ceiling sheet material 1 can be sandwiched between the surfaces. Since the tips of the pressing claw pieces 22c and 22c do not hit the ceiling sheet material 1, the ceiling sheet material 1 can be prevented from being damaged.

  In FIG. 6D, a pressing projection 22ca is formed on the surface of the tip of one pressing claw piece 22c, and the pressing projection 22ca presses the surface of the other pressing claw piece 22c. It has become.

  In FIG. 6E, a pressing convex portion 22ca formed by bending the tip of one pressing claw piece 22c is formed, and the pressing convex portion 22ca is a concave portion 22cb formed on the surface of the other pressing claw piece 22c. It is the structure which press-fits.

  7A, the constricted portions 22b and 22b of the clip body 20 are further recessed inward, and the ceiling sheet material 1 can be sandwiched between the constricted portions 22b and 22b. ing. According to this configuration, the clamping by the upper and lower pressing claw pieces 22c and 22c can be complemented by the clamping of the upper and lower constricted portions 22b and 22b.

  In the above embodiment, when the clip main body 20 is immersed in the cover clip 30, the entire clip main body 20 is illustrated. However, in the immersion state (the elastic pinching portion is urged). Even if it exists, like the thing shown in FIG.7 (b), a part of clip main body 20 may protrude.

  Further, as shown in FIG. 7B, if the tips 22d and 22d (folded portions of the pressing claw pieces 22c and 22c) in the protruding state of the clip body 20 are formed to be curved as shown in FIG. Even when the ceiling sheet material 1 is stretched as in the example, the ceiling sheet material 1 is not likely to be damaged.
