Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-touch clip for connecting and holding a field edge and a field edge support, which are ceiling base materials for holding a ceiling surface material of a building such as a building or a general house.

[0002]

2. Description of the Related Art In a ceiling base structure as shown in FIG. 1, a ridge (2) and a ridge receiver (3) are bridged substantially orthogonally to each other, and both are fixed by a fixing bracket (4). Along with
The field margin receiver (3) is fixed to a roofing material or the like by a hanging bracket (5). And ceiling surface material (6) is separately fixed to field edge (2). In the case of architectural steel ceiling base materials specified in JIS, the fixing brackets (commonly known as clips) used to join the members finally have a process of "bending by hand", resulting in poor workability. . In addition, since it is fixed by bending, it must be returned to its original state by bending in order to release the lock. Since plastic deformation is repeated, it cannot be reused.

In order to omit such a bending step,
Japanese Utility Model Registration No. 3007981 discloses that a substrate (1A) formed in a front rectangular shape to face a web of a rim receiver as shown in FIG. The upper locking side (1B) which is locked from the upper surface to the upper flange of the bent field edge receiver, and the left and right field edge lips engraved below both the left and right sides of the substrate portion (1A). Notches (1C, 1D) are formed in the rear side of the upper locking side (1B). (1E) is formed, and the locking bent portion (1E) is a vertical side (1E1) bent at a right angle downward from the leading edge.
There has been proposed a one-touch clip including an inclined side (1E2) bent obliquely upward from a lower end of the vertical side.

[0004]

In this publication, there is no specification as to how the field receiver is clipped to the field edge with the one-touch clip. However, when viewed from the attached drawings, the notches (1C, 1C,
After mounting the one-touch clip on the field edge using D), the field edge receiver is slid on the field edge lip in the direction in which the web of the field edge contacts the board portion (1A) of the one-touch clip, and Is the guide side, the upper locking side (1B) and the locking bent portion (1).
It is considered that the elastic deformation of E) is used to fit into the space formed by the substrate portion (1A), the upper locking side (1B) and the bending portion (1E) for locking.

[0005] Since this one-touch clip does not have a self-supporting member by itself, in order to join the field edge receiver to the field edge by using this clip, the one-touch clip is held with one hand and the field is held with the other hand. The rim receiver must be pushed into the locking bent portion (1E) against the rigidity of the one-touch clip, and thus connection and fixing must be performed one by one. In addition, when removing the ridge support, the slope side (1E
It is necessary to push up the locking bent portion (1E) obliquely upward by using 2), and the working efficiency is extremely poor.

The present invention has been devised in order to solve such a problem, and has a simple structure of the clip itself, is inexpensive to manufacture, and is easily joined to a steel ceiling base material. It is intended to provide a one-touch clip for use.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The one-touch clip for joining a steel ceiling base material of the present invention has the shape as described above.
After cutting or punching out of the two plates into a very simple shape except for having a cut groove, the two locking pieces (13) are bent from the upper locking side (12), and the two locking pieces (2) are removed from the edge support (14). The two lip contact pieces (15) are bent, and finally the substrate (1
If the upper locking side (12) is bent sequentially from 1),
It can be manufactured very easily. In the second embodiment, which has the web contact piece (17), it is sufficient to simply bend it from the edge support portion (14).

As the steel sheet to be used, galvanized steel sheet,
Various surface-treated steel sheets such as a zinc-aluminum-plated steel sheet and an aluminum-plated steel sheet can be used. For the ridge or ridge support, a thickness of about 0.5 to 1.2 mm is used, but the one-touch clip of the present invention has a thickness of 1.2 to 2.3 mm slightly thicker than the thickness of the ridge or the like. It is preferable to use one having a plate thickness.

The substrate portion (11) formed in a front rectangular shape is brought into contact with a web of a field edge support, and is formed on the upper side of the substrate portion by the lower surface of an upper locking side (12) bent at a right angle forward. The upward movement of the upper flange of the rim support is restricted, and the locking piece (13) bent downward on both sides at the tip end of the upper locking side (12) at the end of the upper surface of the upper flange is located forward of the upper flange. The movement is restricted, and furthermore, a ridge support portion (14) having a width continuous from the substrate portion (11) downward, wider than the substrate portion, and narrower than the web width of the ridge portion; The upward movement of the one-touch clip itself is restricted by the lip contact piece (15) bent at a right angle forward from both upper ends.

Since the distance between the lower surface of the upper locking side (12) and the upper surface of the lip abutting piece (15) is made equal to (web width + field plate thickness) of the field receiver, the field receiver is clipped. By this, it is firmly fixed and held at the field edge. At this time, the substrate (1
If the distance between the front face of 1) and the end face of the locking piece (13) on the board portion side is set to be equal to or more than the width of the flange on the field support, the flange on the field support can be easily attached to the locking piece and the board section. It can be inserted between. Further, when the locking piece (13) is provided such that the end on the substrate side thereof is inclined so as to come closer to the substrate as the distance from the upper locking side (12) increases, the flange on the field support receives the locking piece. And the field edge receiver is firmly fixed and held. A web contact piece (17) bent rearward at a right angle is provided on the lower side of the field edge support part (14) with the upper surface of the lip contact piece (15) and the lower surface of the web contact piece (17). Is provided so as to be equal to (the flange width of the ridge-2 × the thickness of the ridge), the upper surface of the lip abutment piece (15) and the lower surface of the web abutment piece (17) are located on the inner surface of the ridge. In contact with the clip, the relative movement of the clip itself with respect to the field margin is regulated, and the clip is held robust as a whole.

Next, a description will be given of a holding method for connecting and holding a field edge receiver to a field edge using the one-touch clip of the present invention. The runner (7) is fixed to the building wall in a conventional manner. The end of the bezel (2) is fitted into the runner (7) in the same manner as in the prior art. Thereafter, as shown in FIG. 7, a one-touch clip having the shape described in claim 1 is inserted into the inter-lip groove of the field edge with the field edge support portion (14) facing down.
After the rotation, the lip abutment piece (15) of the ridge support portion (14) is lifted upward and is brought into contact with the lower surface of the lip of the ridge. Next, the end of the upper flange of the field margin receiver is connected to the upper locking side (1).
The web comes into contact with the front end of the board part (11) of the one-touch clip by abutting on the boundary edge between the 2) and the locking piece (13), and the entire edge support (3) as the axis in the material length direction. Rotate (twist) so that the field edge (2), field edge receiver (3)
And the one-touch clip (4). If the one-touch clip is inserted and rotated in each of a plurality of ridges, the ridge and the ridge receiver can be fixed at a plurality of locations at the same time, and the operation proceeds extremely efficiently. Then, the whole is fixed to the roof material of the building using the hanging metal fittings (5) as in the conventional method.

Next, a method of fixing the field margin receiver to the field margin using the one-touch clip having the shape specified in claim 2 will be described. Since the one-touch clip of this embodiment has the web contact piece (17), it cannot be inserted from the groove between the lips at the edge. For this purpose, the edge support portion (14) and the web contact piece (17) are inserted into the edge cavity from the edge of the edge in advance so as to enter the web cavity. When a required number of one-touch clips are inserted into a plurality of field edges, respectively, and the one-touch clips inserted into the respective field edges are used one by one, and the field edge receiver is rotated (twisted) in the same manner as described above. One ridge support can be simultaneously fixed to a plurality of ridges at a plurality of locations. In the case where the web contact piece (17) is provided on the lower side of the edge support portion (14) as described in claim 2 of the present invention, the one-touch clip is attached to the edge of the edge (2) before construction. When the one-touch clip is inserted into the hollow portion of the ridge from the portion, the one-touch clip maintains a state of being erected in the normal vertical direction, so that the fitting operation of the ridge receiver (3) can be easily performed.

The present invention is intended to fix a field margin receiver to a field margin by utilizing the rigidity of a cold-rolled steel sheet. Using a normal cold-rolled plated steel sheet and a one-touch clip having dimensions as defined in claims 1 and 2, the field support is fitted using torsion as described in FIG. 7B. At this time, the cold-rolled steel plate clips slightly elastically, and the upper locking side (1
2) opens slightly upward and the lip contact piece (1
5) is slightly curved, and the web portion and the lower flange portion are sequentially received in the expanded space from the upper flange, and then elastically return to the original state, and the substrate portion (11), the upper locking side (1)
2) The ridge receiver (3) is accommodated in the space formed by the locking piece (13) and the lip surface of the ridge, and the lip abutment piece (15) of the ridge support portion (14) from below. Since the above-mentioned space is regulated by being supported, the field margin receiver (3) does not rattle.

Also, when releasing the engagement of the field edge receiver (3), if the field edge receiver (3) is twisted in the opposite direction against the rigidity, the field edge (2) can be moved from the field edge (3). ) Can be easily removed. Board part (11) Upper locking side (12) in front of the upper side
If the distance between the outer surfaces of the locking pieces (13) provided in the above is made larger than the width of the groove between the lips of the field edge, the one-touch clip of the present invention does not fall into the cavity of the field edge from the groove between the lips of the field edge.
Can be used again.

According to a fifth aspect of the present invention, each dimension of the one-touch clip according to the present invention is set between the dimensions of the applicable edge and the edge support.
