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 are used on the surface of conventional ceilings. 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.

  Further, it is also included in the object of the present invention to enable the attachment portion at the ceiling edge of the ceiling sheet material to be stably maintained.

In order to achieve the above object, the ceiling sheet material mounting structure according to claim 1 is configured such that the clip body is inserted into the interior of the long cover clip while elastically deforming the short clip body.

It is comprised from the press nail | claw piece which bent at an acute angle and formed in opposition.

The ceiling sheet material mounting structure according to claim 5 is characterized in that the distance from the base portion of the tip portion of the pressing claw piece is different from each other.

The ceiling sheet material mounting structure according to claim 6 is characterized in that at least one surface of the pressing claw piece is formed with a pressing convex portion that presses the other pressing claw piece.

  According to the ceiling sheet material mounting structure according to claim 1, the cover clip presses the elastic clamping portion from both sides with the clamping pieces against the elastic force of the elastic clamping portion of the internal clip body. Since the clip body is configured to be clamped, the clip body can be fixed and held with the ceiling sheet material sandwiched, and as a result, the ceiling sheet material can be firmly stretched and held.

  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.

  Further, since the cover clip is long, the entire short clip body can be protected within the cover clip, and a stable clamping state of the ceiling sheet material by the clip body can be maintained.

  Furthermore, since the slip prevention means for restricting the movement in the width direction of the base portion of the clip body immersed in the cover clip is provided in the vicinity of the proximal end portion of the sandwiching piece, the clip body is further stabilized.

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

1-6 is explanatory drawing of the attachment structure (seat fixture which consists of a clip main body and a cover clip ) concerning the ceiling sheet material which concerns on one Embodiment (reference example) of this invention.

  The seat fixture 10 is a fixture for stretching and attaching the ceiling sheet material 1 disposed on the ceiling 2 (see FIGS. 6B and 10), and includes a plurality of short clip main bodies 20. , And a long cover clip 30 for interiorizing them.

  The cover clip 30 is preferably formed in a long shape corresponding to one edge of the ceiling sheet material 1 to be attached, for example, in which a plurality of short clip bodies 20 are arranged therein. At least, the cover clip 30 may be longer than the clip body 20 and have a length that can cover the entire length of the clip body 20.

  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 body 20 is made of a thin plate material having a spring property of a metal or a synthetic resin, and extends from the both ends in the width direction of the base portion 21 and the elastic pinching portions 22 and 22 extended in the front end side. And.

  That is, the clip main body 20 is formed as a concave groove body having an opening that widens from the base 21 (bottom) toward the tip.

  Each elastic pinching portion 22 includes a pinching piece 22 a and a pressing claw piece 22 b that is bent and extended so that the pinching piece 22 a is folded back toward the base portion 21.

  The pressing claw piece 22b is bent so as to form an acute angle with the sandwiching piece 22a, and extends to a position substantially in the middle of the sandwiching piece 22a. The tip of the pressing claw piece 22b and the other pressing claw piece An opening 23 is formed between the tip of 22b. The ceiling sheet material 1 can be taken in and out of the opening 23.

  As will be described later, when the front end of the clip main body 20 protrudes from the opening 33 of the cover clip 30, the clip main body 20 is in a state where the sandwiching pieces 22a and 22a are opened without acting on the elastic force. The C-shaped part formed by the sandwiching pieces 22 a and 22 a and the pressing claw pieces 22 b and 22 b in this state constitutes the receiving part 24 of the ceiling sheet material 1 inserted from the opening part 23.

  In the present embodiment, the pressing claw pieces 22b and 22b are configured such that the lengths thereof are different from each other and the tip positions thereof are shifted, but they may be the same length.

  On the other hand, the cover clip 30 is formed thicker than the clip body 20, is formed as a concave groove body that opens in the same direction as the opening of the clip body 20, and the opening 33 is slightly narrower than the bottom 31. It has become. The opening width dimension of the opening 33 is larger than the width dimension of the base portion 21 of the clip main body 20 as shown in FIG. 2A, and the dimensional relationship is such that the clip main body 20 can be easily inserted from the base 21 side. It has become.

  Moreover, the both wall parts of the ditch | groove body comprise the clamping pieces 32 and 32, and become the structure which press-clamps the clip main body 20 equipped internally from both sides.

  Ribs 31a and 31a that protrude slightly outward (to the right in the figure) are formed at both ends in the width direction of the bottom portion 31, and a portion of the cover clip 30 that is slightly closer to the center than the rib 31a of the bottom portion 31 is formed inward. An inner wall is formed to connect the central portion of the sandwiching piece 32 close to the rib 31a. Both the inner walls constitute a displacement prevention means including movement restriction walls 34 and 34 for restricting the movement in the width direction of the base 21 of the clip body 20 immersed in the cover clip 30.

  The seat fixture 10 has a structure in which the ceiling sheet material 1 can be fixed in a state where the clip main body 20 is housed in the cover clip 30 (see FIG. 2C), and FIGS. As described above, the protrusion of the clip body 20 from the opening 33 of the cover clip 30 and the insertion into the cover clip 30 can be freely performed.

  The clip body 20 can be flattened by pressing the C-shaped sandwiching pieces 22a, 22a from both outer sides, and when the clip body 20 is in a protruding state from the opening 33 of the cover clip 30, it is elastic. It is in an open state where no force acts (see FIG. 2 (a)). Further, when the clip main body 20 is in the immersive state, the sandwiching pieces 22a and 22a are elastically deformed and become a flat state in which a resilient force is applied from the inside of the cover clip 30 (see FIG. 2C). .

  That is, the cover clip 30 resists the resilience of the sandwiching pieces 22a and 22a of the clip body 20 provided inside, and the sandwiching pieces 32 and 32 have a strong elastic force so that the sandwiching pieces 22a and 22a are placed on both outer sides. The pressing pieces 22a and 22a act so as to maintain the proximity state.

  Further, since the width dimension of the opening 33 of the cover clip 30 is larger than the width dimension of the base portion 21 of the clip body 20, the interior operation of the clip body 20 can be easily performed. The clip main body 20 is not easily popped out by pressing and holding the pieces 32 and 32.

  When the clip body 20 is mounted in the cover clip 30, the base 21 is in contact with the inner bottom surface of the bottom 31 of the cover clip 30, and the end in the width direction of the base 21 is the movement restricting wall 34. It will be in a state where it is in contact with or close to, and it will be almost impossible to move in the width direction.

  The clip main body 20 can be attached to the cover clip 30 by sliding from the end in the longitudinal direction with the clip main body 20 flattened.

  As shown in FIG. 5, the ceiling sheet material 1 is inserted into the base 21 side from the opening 23 formed between the pressing claw pieces 22 b and 22 b when the clip body 20 is in a protruding state. In this state, the pressing claw pieces 22 b and 22 b 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 with the ceiling sheet material 1 sandwiched between the pressing claw pieces 22b and 22b is pushed into the cover clip 30 through the opening 33, the clamping pieces 22a and 22a and the pressing claw pieces 22b and 22b are inserted. Are close to each other so that the receiving portion 24 is narrowed, and in particular, the tip portions of the pressing claw pieces 22b and 22b are in elastic contact with the ceiling sheet material 1 interposed therebetween. 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 pressing claw pieces 22b and 22b.

  After the clip body 20 is immersed in the cover clip 30, the opening 33 of the cover clip 30 is narrower than the bottom portion 31, so that the clip body 20 does not jump out even when a tension load is applied by the ceiling sheet material 1.

  When the clip main body 20 is completely immersed inside the cover clip 30, the movement of the base portion 21 in the width direction is restricted by movement restriction walls 34, 34 provided in the vicinity of the base end portions of the sandwiching pieces 32, 32 of the cover clip 30. Thus, it is possible to maintain a stable state without moving out of position. Therefore, the stable clamping state by the clip main body 20 of the ceiling sheet material 1 can be maintained.

  In particular, in one cover clip 30, since all the clip main bodies 20 attached thereto are restricted in movement in the width direction, the ceiling sheet material 1 can be prevented from being displaced, twisted, damaged, and the like.

  Further, when removing the ceiling sheet material 1 from the seat fixture 10, the ceiling sheet material 1 sandwiched between the clip main bodies 20 may be pulled so that the clip main body 20 protrudes from the opening 33 of the cover clip 30. .

  If the ceiling sheet material 1 is pulled strongly, the cover clip 30 has a shape constricted toward the opening 33, so that the clip body 20 is further elastically deformed into a flat state, and the tip protrudes from the opening 33. After that, since the width dimension of the opening 33 of the cover clip is larger than the width dimension of the base portion 21 of the clip body 20, the clip body 20 can be easily detached without being caught.

  According to such a mounting structure of the ceiling sheet material 1, the cover clip 30 is elastically sandwiched between the sandwiching pieces 32 and 32 against the elastic force of the elastic sandwiching portions 22 and 22 of the internally mounted clip body 20. Since the attachment portions 22 and 22 are configured to be pressed and clamped more, the clip body 20 can be fixed and held in a state where the ceiling sheet material 1 is sandwiched, and the sheet fixture 10 is attached to the ceiling 2 as will be described later. By fixing, 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 clamping part 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 an accurate dimension in advance, and the dimension 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.

  The sheet fixture 10 (the clip body 20 and the cover clip 30) sandwiching the ceiling sheet material 1 as described above is provided on the edge of the ceiling 2 or the edge around the ceiling, as shown in FIG. The interior is fixed to the fixing portion 40.

  The fixture fixing portion 40 is a rod-like body that is fixed along the edge of the ceiling 2. The fixture piece 41 is fixed to the ceiling with a fixture 43 such as a bolt or a screw, and below the fixture piece 41. And a fixed piece portion 42 extending in an L shape.

  On the lower surface of the mounting piece portion 41 and the upper surface of the horizontal piece 42a of the fixed piece portion 42, concave and convex surfaces 41a and 42aa are formed in which concave portions and convex portions extending along the longitudinal direction are alternately continued in the short direction. . 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. 6 (b), one rib 31a of the cover clip 30 of the seat fixture 10 is fitted into the concave portion of the concave and convex surface 42aa of the horizontal piece 42a, and the sandwiching piece 32 positioned diagonally with the rib 31a. The sheet attachment tool 10 is fixed so that it does not come out by fitting the tip of the sheet fitting into the concave portion of the concave and convex surface 41a on the lower surface of the attachment piece portion 41 so that the sheet attachment device 10 is inclined toward the vertical piece 42b. can do. The mounting piece 41 does not have to be formed with an uneven surface 41 a, and when the tension by the ceiling sheet material 1 is applied, the tip of one clamping piece 32 of the cover clip 30 is the lower surface of the mounting piece 41. What is necessary is just the structure latched to.

  Thus, since the seat fixture 10 is inclined so as to close the opening, and the ceiling sheet material 1 protruding from the opening is bent in the lateral direction, the ceiling sheet material is provided. Even if a tension load of 1 is applied, the clip body 20 does not jump out of the cover clip 30, and therefore the ceiling sheet material 1 is not likely to come off.

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

  FIG. 7 is an explanatory view showing an example of the shape of the pressing claw piece 22b. In FIGS. 7 (b) to (e), the pressing claw piece 22b of portion A shown by a one-dot chain line in FIG. An example of the sandwiched shape of 22b is shown in an enlarged view.

  In all these four examples, one pressing claw piece 22b is formed longer than the other pressing claw piece 22b, 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.

  The thing of FIG.7 (b) becomes a structure which presses the surface of the other press claw piece 22b with the front-end | tip of one press claw piece 22b. Since it is not the structure which presses between front-end | tips, damage to the ceiling sheet material 1 can be prevented.

  The thing of FIG.7 (c) is made to be able to clamp the ceiling sheet | seat material 1 between surfaces by bending the front-end | tip of the press nail | claw pieces 22b and 22b. Since the tips of the pressing claw pieces 22b and 22b do not hit the ceiling sheet material 1, the ceiling sheet material 1 can be prevented from being damaged.

  7 (d) has a configuration in which a pressing projection 22ba is formed on the surface of the tip of one pressing claw piece 22b, and the pressing projection 22ba presses the surface of the other pressing claw piece 22b. It has become.

  In FIG. 7E, a pressing convex portion 22ba is formed by bending the tip of one pressing claw piece 22b, and the pressing convex portion 22ba is a concave portion 22bb formed on the surface of the other pressing claw piece 22b. It is the structure which press-fits.

  In the embodiment described above, the movement restricting walls 34 and 34 are provided inside the base end portions of the sandwiching pieces 32 and 32 to form a double structure, but the movement restricting walls 34 and 34 are provided on the base of the sandwiching pieces 32 and 32. It is good also as a structure comprised by the edge part. Further, instead of providing the movement regulating walls 34, 34, a pair of protrusions may constitute the shift prevention means.

  Furthermore, it is good also as a structure which controls the movement of the base 21 of the clip main body 20 in the width direction by uneven | corrugated fitting with the outer surface of the base 21 of the clip main body 20, and the inner bottom face of the cover clip 30.

FIG. 8 and FIG. 9 are diagrams showing an example of a slip prevention means by concave-convex fitting (Example) . FIGS. 8A to 8C are front views showing the state transition of the seat fixture, and FIG. 9 is a right side view in FIG. 8C (viewed from the bottom side of the cover clip). .

  Two protrusions 25 are formed along the longitudinal direction at the center in the width direction of the outer surface of the base 21 of the clip body 20. A long hole 35 is formed in the center in the width direction of the bottom 31 of the cover clip 30 along the longitudinal direction.

  In a state where the clip main body 20 is immersed in the cover clip 30, the two protrusions 25, 25 are fitted into the long holes 35 and the movement of the base 21 in the width direction is restricted.

  In addition, in order not to reduce the strength of the cover clip 30, the cover clip 30 may be provided with a fitting groove in which the inner bottom surface side of the bottom portion 31 is recessed instead of the long hole 35.

  In addition, when the mounting position of the clip body 20 to the cover clip 30 is fixed, a recess corresponding to each protrusion 25 or a long hole corresponding to each clip body 20 is provided so as not to reduce the strength of the cover clip 30. You may make it provide.

  According to such a deviation prevention means by the protrusion 25 and the recess (long hole 35), it is possible to easily form a fitting structure simply by providing a protrusion on one of the clip body 20 and the cover clip and a recess on the other. Therefore, it is possible to easily prevent displacement.

  Furthermore, as a means for preventing deviation due to uneven fitting, an uneven portion in which uneven stripes continue in the width direction is provided on the outer surface of the base portion 21 of the clip body 20 and the inner bottom surface of the bottom portion 31 of the cover clip 30, and both uneven portions are provided. It is good also as a structure to fit.

  Moreover, it is good also as a structure which forms in the both surfaces of the outer surface of the base 21 of the clip main body 20, and the inner bottom face of the bottom part 31 of the cover clip 30, and does not slip | deviate by contact (friction) of both surfaces.
