Description

  The present invention relates to a fixing clip, and more particularly, to a fixing clip used to fix a field edge and a field edge receiver, which are part of a ceiling base material, to each other.

  Generally, a ceiling panel as an interior material is attached to a ceiling portion in a building structure such as a reinforced concrete structure. The ceiling panel is supported by a field edge and a field edge receiver that are installed between the ceiling panel and the frame ceiling surface of the building structure. Such field edges and field edge receivers are very well known, and detailed description of their structure is omitted. The ceiling panel is directly attached to the field edge, and this field edge is connected to the field edge holder suspended by anchor bolts attached to the building ceiling of the building structure using a fixing clip. . The fixing clip is already well known as disclosed in Patent Document 1, and generally, a field edge receiving locking part for locking to the field edge receiving and a field edge holding part for holding the field edge. It consists of and.

  The field edge receiving and engaging portion includes a horizontal plate portion along a side wall (upper side wall) which is an upper surface of the field edge receiving member, and a bending engagement piece extending from the edge of the horizontal plate portion and bent downward. I have. This bending locking piece is provided with a protrusion that contacts the lower surface (back surface) of the upper side wall of the field receiver. Further, the field edge holding part is provided with a claw part that engages with the field edge lip part, and this claw part is defined by three parts of the flange surface, the inner edge wall, and the side wall forming the lip part. It is inserted into the groove and engaged with the inner edge wall. Thereby, the field edge is connected to the field edge receiver by the fixing clip.

  By the way, in this fixed clip, the field edge receiving latching part and the field edge holding part are provided at the upper part and the lower part of the flat plate board part, and the field edge receiving latching part is only in one side direction from the board board part. Since it extends, it is formed in an inverted L shape when viewed from the side. For this reason, when acting force such as rolling due to an earthquake is exerted on the field edge or the field edge receiver, the anchor plate portion of the fixed clip attached to the field edge receiver tilts or falls down in the longitudinal direction of the field edge. In some cases, the claw portion of the field edge holding portion may come off from the lip portion of the field edge. In order to compensate for the drawbacks of the conventional fixing clips, a plurality of fixing clips sequentially arranged in a single field edge holder are mounted by alternately changing their directions when actually constructed.

  Moreover, the use of a clip reinforcing member (Patent Document 2) is known as another structure for preventing the fixed clip from falling off the field edge even when the field edge or the field edge receiver receives a large acting force due to an earthquake or the like. . This clip reinforcing member includes a rectangular top plate that covers the horizontal plate portion of the fixed clip, and at each lower end portion of the pair of sandwich plates bent downward from a pair of opposite edges of the top plate, A pair of lip protrusions are formed in the width direction of the field edge, and these lip protrusions are engaged with the lip wall of the field edge. When this clip reinforcing member is used, since the pair of clip plates are provided on both sides of the field edge receiver, even if the fixed clip repeatedly receives some acting force from the longitudinal direction of the field edge, It becomes difficult to come off the edge.

JP 2007-247217 A JP 2007-297857 A

  However, as shown in FIG. 5 of Patent Document 2, the clip reinforcing member disclosed in Patent Document 2 is defined by the lip wall and the side wall only by the lip protrusion abutting on the lip wall of the field edge. The structure is not positively inserted into the groove. Therefore, when a force is applied from the width direction of the sandwiching plate (longitudinal direction of the edge receiving), the other lip protrusion is directed from the lip wall toward the inside of the field edge so that the lip protrusion on one side enters the groove. As a result, the clip reinforcing member does not perform its original reinforcing function, and eventually, there is a problem that the above-described action force is exerted on the fixed clip and falls off the edge.

  In addition, since such a reinforcing member is a separate member from the fixed clip, using this reinforcing member increases the number of parts and increases the number of mounting work steps in a narrow space such as the ceiling. Further, in the conventional fixing clip, the cross-sectional shape of the field receiver has to be at least a flange or the like, for example, a U-shape or a horizontal H shape, and the degree of freedom in selecting a member is low. In addition, the direction of attachment must be alternated for one field receiver, and there is a problem that it takes time and effort.

  The object of the present invention is to solve such a conventional problem, and it is difficult for the fixing clip to come off from the field edge even if it is shaken by an earthquake or the like, and the mounting work is easy, and it can be applied to a field edge receiver of any cross-sectional shape. However, it is to provide a fixing clip that can be used.

The present invention comprises a pair of side walls that rise substantially perpendicularly from both side edges of the main wall in the same direction, and a lip portion that is formed to project from each end edge of each side wall to the opposite inner side of the side wall, The lip portion has a long field edge including a flange surface projecting inwardly from each edge of each side wall and an inner edge wall slightly projecting from the inner edge of the flange surface toward the main wall. It is a fixed clip to which a long field receiver that is supported by the frame and intersects the field edge substantially perpendicularly is attached. A field edge engaging portion that engages with the edge, and the field edge receiving fitting portion includes a top surface portion and a pair of side surface portions that extend in the same direction from a pair of side edges facing the top surface portion. A pair of joints extend from each side surface portion of the field edge receiving fitting portion in a direction opposite to the upper surface portion. Each leg surface portion is open in a direction away from the side surface portion, and the end of the leg surface portion located on the opposite side of the side surface portion and the width dimension in the vicinity thereof are the lip portions facing the field edge. A pair of engaging protrusions inserted into a lip groove defined by a flange surface forming an edge lip portion, an inner edge wall, and a side wall are formed at the end of the leg surface portion. The engaging projection piece is formed to protrude outward in the width direction of the leg surface portion, the engagement projection piece is bent upward from the surface of the leg surface portion, and the interval between the two bent engagement projection pieces in the width direction is set. When the fixed clip is attached to the field edge receiver, the engagement protrusion piece is deformed while pressing the lip part and is press-fitted into the lip groove. It is to firmly connected to the receiving field edge the field edges engage the cortex edge

  In another embodiment of the fixing clip according to the present invention, the engaging protrusion is projected outward in the width direction on both side portions on the edge side of the leg surface portion and bent upward from the surface of the leg surface portion. The piece forms a V-shaped hook groove at the upper edge and the side edge of the leg surface portion.

  As another embodiment according to the fixing clip of the present invention, the engaging projection piece is a substantially square plate-like piece having a surface of a predetermined size, and the V-shaped hook groove is a plate-like piece. The upper edge and the side edge of the leg surface portion are formed.

  According to the fixing clip of the present invention, the distance between the distal end portions of the two engaging projection pieces formed at the end portion of the leg surface portion and bent upward from the surface of the leg surface portion is the edge edge. Since the distance between the lip portions is slightly larger than the distance between the lip portions, when the end of the leg surface portion is forced into the groove of the field edge, the entire surface of the engaging protrusion piece is oblique to the inner shoulder portion of the lip portion. The side wall including the lip portion is gradually expanded (flexed) while being slidably contacted with each other, and at the same time, it deforms itself to reduce the distance between the tip portions. And if a leg surface part is continuously pushed in into a groove part, a pair of engaging protrusion piece will be finally latched in a lip groove. If it will be in this state, the space | interval between the front-end | tip parts of each engagement protrusion piece and the space | interval between lip parts will restore | restore to the original length substantially.

  As a result, the pair of engaging protrusions on each leg surface portion will not come out of the lip groove, and even if an action force due to an earthquake or the like acts on the fixed clip via the field edge, the engaging protrusion pieces are engaged in the lip groove. It will continue to fit and the securing clip will not come off the edge. In addition, since the fixing clip of the present invention includes a field edge receiving fitting portion that is mounted so as to straddle the field edge receiver, the selection range of the cross-sectional shape of the field edge expands, in other words, the field edge receiver As long as the shape is in contact with the upper surface of the field edge receiving portion and the pair of side surface parts, the restriction on the cross-sectional shape of the field edge receiver is greatly reduced, and selection of the field edge receiver is possible. The degree of freedom increases.

  Further, according to the fixing clip of the present invention, the engaging projection piece forms a V-shaped hook groove (locking groove) at the upper edge and the side edge portion of the leg surface portion. It is possible to reliably prevent the end of the inner edge wall of the field edge from entering and fixing the clip from the field edge.

  Further, according to the fixing clip of the present invention, the engaging projection piece is a substantially rectangular plate-like piece having a surface of a predetermined size, and the upper edge of the plate-like piece and the side edge of the leg surface portion. Since the V-shaped hook groove is formed, when the engaging projection piece of the fixing clip is slid into the lip portion of the field edge, the pushing force is dispersed to bend the engaging projection piece itself. It does not break at the base of the surface part and can be easily attached to the field edge.

  Hereinafter, the fixing clip of the present invention will be described in more detail based on a preferred embodiment shown in the drawings. As shown in FIGS. 1 and 3, a fixing clip 10 according to an embodiment of the present invention is a hanger attached to an anchor bolt L embedded in a frame ceiling K of a building structure such as a reinforced concrete structure, for example. This is for connecting a field edge receiver 20 supported by being suspended by H and a field edge 30 that intersects the field edge receiver 20 almost right below. The ceiling panel P is attached to the field edge 30 using screws or the like.

Before describing the detailed configuration of the fixing clip 10 according to the embodiment of the present invention, the cross-sectional shape of the field edge 30 will be described. The field edge 30 is a long member formed from, for example, a galvanized steel sheet. The field edge 30 is composed of a flat main wall 31, a pair of side walls 32 rising in the same direction from both side edges thereof at a substantially right angle to the main wall 31, and an inner side of each side wall 32 facing the side wall 32. And a lip portion 33 formed so as to protrude in the direction. As a result, the field edge 30 has a U-shaped cross section including a groove portion defined by the main wall 31 and the two side walls 32, and therefore the lip portion 33 exists on both sides of the opening of the groove portion .

  Further, the lip portion 33 is formed by a flange surface 33 a projecting inward from each end edge of each side wall 32, and an inner edge wall 33 b projecting slightly from the inner edge of the flange surface 33 a toward the main wall 31. . As a result, a lip groove 33c defined by the flange surface 33a, the inner edge wall 33b, and the side wall 32 is formed inside each lip portion 33. The lip groove 33c is provided in the fixing clip 10 described later. The engaging projection piece 14 is engaged. On the other hand, the field edge receiver 20 is a long channel member having a U-shaped cross section as shown in FIG. 1, and is formed of a galvanized steel plate or the like, similar to the field edge 30. The field edge receiver 20 uses such a channel member based on the configuration of a conventional fixed clip, but is not limited to such a channel shape as long as the fixed clip 10 of the present invention is used.

  Therefore, the fixing clip 10 according to an embodiment of the present invention will be described as follows. As shown in FIGS. 1 and 2, the fixing clip 10 includes a field edge receiving fitting portion 11 into which the field edge receiving 20 is fitted, and a field edge engaging portion 12 that engages with the field edge 30. . The fixing clip 10 is formed from a relatively thin galvanized steel sheet or the like, and thus has inherent elasticity. The field edge receiving / fitting portion 11 is formed of an upper surface portion 11a and side surface portions 11b extending in the same direction from a pair of opposing side edges of the upper surface portion 11a, and has a U-shaped cross section. The field edge engaging portion 12 includes a pair of leg surface portions 13 extending from each side surface portion 11b of the field edge receiving fitting portion 11 in a direction opposite to the upper surface portion 11a, and each leg surface portion 13 is separated from the side surface portion 11b. The legs are spaced apart from each other in the direction. The field edge receiving fitting part 11 and the field edge engaging part 12 are integrally formed.

  On both sides of the end portion 13a of the leg surface portion 13 existing on the side opposite to the side surface portion 11b, a pair of engagements having a surface of a predetermined size having a substantially square shape when the leg surface portion 13 is viewed from the front. The protruding piece 14 is formed so as to protrude outward in the width direction of the leg surface portion 13. Therefore, each engagement protrusion piece 14 includes a front surface 14 a and a back surface 14 b that are respectively continuous with the front surface 13 a and the back surface 13 b of the leg surface portion 13. The engaging projection piece 14 is bent in a direction in which the surface 13a of the leg surface portion 13 is directed around a connecting portion with the leg surface portion 13 (an extension line portion of the side edge 13d of the leg surface portion 13). More specifically, the front surface 14a and the back surface 14b are located on the same plane as the front surface 13a and the back surface 13b of the leg surface portion 13 before the engagement protrusion pieces 14 are bent. The upper edge 14c of the piece 14 and the side edge 13d of the leg surface portion 13 form approximately 90 degrees.

However, the engaging projection piece 14 is bent in the direction in which the surface 13a of the leg surface portion 13 faces. Specifically, the engagement projecting pieces 14, it is bent at an angle less than 90 degrees to the plane of time was flat and the surface 13a of the leg surface 13, preferably, are bent at 30 to 60 degrees ing. When the engagement projection piece 14 is bent at such an angle, a V-shaped hook groove 15 is formed by the upper edge 14 c of the engagement projection piece 14 and the side edge 13 d of the leg surface portion 13.

  Next, with respect to how the fixing clip 10 is attached when the field clip 30 is connected to the field edge receiver 20, the dimensions of the leg surface portion 13 of the fixing clip 10 and the engagement protrusions 14 are further increased. The detailed shape and dimensions will be described below. The fixed clip 10 is a field edge facing the frame ceiling K so that the field receiver 20 is inserted into the field receiver fitting portion 11 of the fixed clip 10 at the intersection of the field receiver 20 and the field edge 30. It is pressed and mounted from above the upper side wall 21 of the receiver 20. When the fixing clip 10 is attached to the field edge receiver 20 in this way, the two leg surface portions 13 extending toward the field edge 30 located on the lower side of the field edge receiver 20 have both ends 13a on both sides. The back surface 14b of the engaging projection piece 14 formed on the abutting portion abuts against the inner shoulder portion (the connecting portion between the flange surface 43a and the inner edge wall 43b) 33d of each lip portion 43 of the field edge 40. In other words, as shown in FIG. 4, the fixing clip 10 has a dimension W <b> 1 between the front end portions (side edges 14 d) in the width direction of the two engaging projection pieces 14 that are bent with respect to the leg surface portion 13. The width between the opposing side surfaces 32 of the field edge 11, that is, the width of the groove 34, is smaller than the distance W <b> 2 between the inner shoulders 33 d of the lip 33 of the field edge 30.

In addition, the dimension W3 between the side edges 13d of the leg surface portion 13 forming the V-shaped hook groove 15 in cooperation with at least the upper edge 14c of the engaging protrusion piece 14 is the inner side of the lip portion 33 of the field edge 30. It is made smaller than the dimension between shoulder parts 33d. Therefore, if the engagement protrusion piece 14 is not formed, the end portion 13 c of the leg surface portion 13 and its vicinity can enter between the inner shoulder portions 33 d of the lip portion 33 of the field edge 30.

By the way, the engaging clip 14 does not enter the groove portion 34 beyond the inner shoulder portion 33d of the lip portion 33 only by trying to put the fixing clip 10 on the edge receiving portion 20 . However, two legs face 13, elastically deformed so as thus Ashimenbu 13 Waso open leg degree in about to be mounted with a force retaining clips 10 are subsequently from being put on the field edge receiving 20 increases To do. In other words, the two leg surface portions 13 are further expanded, and the press contact force at which the back surface 14b of the engaging protrusion 14 abuts against the inner shoulder portion 33d of the lip portion 33 is also increased.

  In this state, that is, the fixed clip 10 is completely attached to the field receiver 20, and accordingly, the two leg surface portions 13 are further opened, and the back surface 14b of each engaging projection piece 14 is the inner shoulder portion of the lip portion 33. When the operator forcibly applies a pressing force to the two leg surface portions 13 in a direction opposite to the opening leg direction (a direction in which the two leg surface portions 13 approach each other) from the state of being in pressure contact with 33d, the lip portion 33 is provided. The engaging projection piece 14 whose back surface 14b is in pressure contact with the inner shoulder portion 33d begins to deform in the bending direction due to the increased pressing force, and at the same time, to the lip portion 33 of the field edge 30 by the opposing engagement projection piece 14 The both side walls 32 bend outward by the pressing force, and the dimension between the inner shoulder portions 33d of the lip portion 33, that is, the opening width of the groove portion 34 is slightly increased in accordance with the change of the both.

  Due to the size reduction between the front end portions (side edges 14 d) due to the deformation of the engagement protrusion pieces 14 and the enlargement between the inner shoulder portions 33 d of the lip portion 33 of the field edge 30, the engagement protrusion pieces 14 have their back surfaces. 14 b enters the groove 34 while sliding on the inner shoulder 33 d of the lip 33. At this time, since the engaging projection piece 14 is a substantially rectangular plate-shaped piece as described above, the pressure contact force received from the inner shoulder portion 33d of the lip portion 33 is dispersed throughout the engaging projection piece 14. Become. Therefore, the engaging projection piece 14 is flexed exclusively without applying a large bending stress to the root of the leg surface portion 13, that is, the extended line portion of the side edge 13 d of the leg surface portion 13. The operator stops applying the pressing force to the two leg surface portions 13 of the fixing clip 10 at the same time that the engaging projection piece 14 enters the groove portion 34 of the field edge 30.

  As a result, the two leg surface parts 13 spring up due to the elasticity of the material and return to the original open leg state. At the same time, the engagement protrusions 14 that have been slightly deformed also return to the original state. The opening width between the inner shoulder portions 33d of the lip portion 33 of the field edge 30 that has been spread out by the piece 14 also returns to the original state. As a result, the intersection (tip corner) of at least the upper edge 14c and the side edge 14d of the engaging projection piece 14 projecting from both side portions of the end portion 13a of each leg surface portion 13 enters the lip groove 33c of the lip portion 33. The inner side of the lip 33 is locked. Thereby, even if an external force due to an earthquake or the like acts on the ceiling panel support structure from the field edge receiver 20 and the field edge 30 connected by the fixing clip 10, the front end corner portion of the engagement protrusion piece 14 is in the lip groove 33 c. The fixing clip 10 is not detached from the field edge 30.

  Since the fixing clip 10 has the above-described structure, even if an action force due to an earthquake or the like acts on the fixing clip 10 via the field edge 30 and the field edge receiver 20, the fixing clip 10 is separated from the field edge 30 and the field edge receiver 20. It will not come off. However, loosening (roughness) may occur in the engagement between the fixed clip 10 and the field edge receiver 20 and the engagement between the fixed clip 10 and the field edge 30 due to various causes during a long period of use. Therefore, as shown in FIGS. 6 and 7, the opening holes 16 are formed in the upper surface portion 11 a of the fixing clip 10 and one side surface portion 11 b located outside the side wall 22 of the field edge receiver 20. It is also preferable that the tightening bolt 17 is screwed into the opening hole 16. Specifically, an opening hole 16 is formed at substantially the center of each of the upper surface portion 11a and one side surface portion 11b, and at the same time, the peripheral portion of the opening hole 16 is bulged outward.

  Since the fixing clip 10 is formed of a relatively thin galvanized steel plate or the like as described above, it is not necessary to cut a screw at the inner peripheral edge of the opening hole 16, and the inner peripheral edge of the opening hole 16 itself is a screw of the tightening bolt 17. Screw into the groove. As a result, when loosening (backlash) occurs in the fitting between the fixing clip 10 and the field receiver 20, when the tightening bolt 17 screwed into the opening hole 16 of the side surface portion 11b is rotated in the insertion direction, the tightening bolt 17 When the front end of the fixing clip 10 abuts against the side wall 22 of the field receiver 20 and the tightening bolt 17 is further tightened, the other side surface portion 11 b of the fixing clip 10 comes into pressure contact with the edge portion of the upper wall 21 in the field edge receiver 20. As a result, the holding force with respect to the field edge receiver 20 in the field edge receiving fitting part 11 of the fixed clip 10 is enhanced.

  Further, when the engagement between the fixing clip 10 and the field edge 30 is loosened (backlash), when the tightening bolt 17 is screwed into the opening hole 16 and rotated in the insertion direction, the tip of the tightening bolt 17 becomes the field edge. When the fastening bolt 10 is further tightened by coming into contact with the upper side wall 21 of the receiver 20 and the fastening bolt 17 is further tightened, the fixing clip 10 moves in a direction in which the upper surface portion 11a is relatively separated from the field edge receiver 20, whereby each leg surface portion 13 is The end 13a moves in a direction to exit from the groove 34 of the field edge 30. As a result, the front end corners of the engaging projection pieces 14 provided on both sides of the end portions 13a of the leg surface portions 13 bite further into the lip grooves 33c of the lip portion 33, and the engaging force is increased. Such loosening prevention work can be performed at the time of inspection of the frame structure, and as a result, the strong connection between the field edge receiver 20 and the field edge 30 by the fixing clip 10 can be maintained for a long time.

  In the fixing clip of the present invention, the field edge receiving fitting portion 11 may have any shape as long as the field edge receiver 20 can be relatively fitted therein. 20 can have a cross-sectional shape corresponding to the field edge receiving fitting portion 11, and the degree of freedom in selecting a cross-sectional shape as the field edge receiver 20 is improved. Of course, the field edge receiver 20 may be wood or a resin material. Further, as is apparent from the above description, the fixing clip 10 is always manufactured in accordance with the dimensions of the field edge receiver 20 and the field edge 30, but for example, the field edge receiver 20 used for a ceiling support structure. Since the edge and the edge 30 are standardized, if a fixed clip of several sizes is manufactured corresponding to these standard products, it can be used for any ceiling panel support structure. .

  In the above-described embodiment of the fixing clip of the present invention, the ceiling panel support structure using the field edge and the field edge receiver is exemplified as a case where the field edge and the field edge receiver are connected. The present invention is not limited to such an embodiment. For example, it can be used for fixing base materials disposed on the wall surface of the casing as an interior panel support structure for supporting an interior wall or the like.
