Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a field edge support member used for attaching a field edge, which is a base material for attaching a finishing material for building interiors, to a concrete foundation.

[0002]

2. Description of the Related Art As a finishing material for the interior of a building, there are a ceiling plate to be attached to a ceiling portion, a wall material to be attached to a side wall portion and the like, and many base materials are usually used for attaching these. For example, taking a suspended ceiling as an example, as shown in FIG. 7, a bolt 71 is hung from a concrete base, a hanging metal fitting 72 is attached to this bolt 71, a field edge receiver 73 is attached to this hanging metal piece 72, and this field edge is attached. The field edge 75 is attached to the receiver 73 by the clip 74. FIG. 8 is an enlarged view showing a state in which the clip 74 is joined at the intersection of the field receiver 73 and the field edge 75.

As described above, the conventional field rim support requires many parts, so that not only the weight becomes large, but also the construction and the part management become difficult. There is also a problem that construction is difficult especially in a narrow ceiling space. A number of relatively simple field support structures have been proposed for the purpose of solving such problems (eg, actual fair 3-
No. 42166, Japanese Utility Model Publication No. 3-42167, etc.).

[0004]

However, the conventionally proposed field edge support structure still has problems to be solved. Japanese Utility Model Publication No. 3-42166, Japanese Utility Model Publication No. 3-4216
All of the gazettes of No. 7 perform field edge support using suspension bolts and suspension fittings, and the principle configuration is the same as that of FIG. 7. A position adjusting disk is provided to adjust the horizontal position of the field edge, but it still requires a relatively large space between the field edge and the concrete foundation. Further, the hanging metal fitting has a locking piece having directionality, and is held in a predetermined direction, fitted into the field edge, and then rotated to be locked to the field edge. Therefore, the operation of attaching the field edge is not easy.

It is an object of the present invention to provide a field edge support member which makes the space between the field edge to be attached and the concrete base extremely small and enables the field edge to be attached by a simple one-touch operation. .

[0006]

SUMMARY OF THE INVENTION The present invention is a field edge supporting member for attaching a field edge having a U-shaped cross section and having hook portions projecting inward along both upper edges thereof to a concrete foundation. It is characterized in that it has a locking portion that is attached to a concrete base and is snap-fitted to the hook portion of the field edge. The present invention also relates to a field edge support member for attaching a field edge having a U-shaped cross section and having hook portions projecting inward along both upper edges thereof to a concrete base, and a male screw portion and a male screw portion thereof. It has a flange part formed at the base end, the flange part has a first member attached in close contact with the concrete base, and a screw hole screwed into the male screw part of the first member, and has a side circumference. A second member having a locking portion that is snap-connected to the hook portion of the field edge is provided on the surface. The present invention is further characterized in that the second member has a rotary operation knob portion having a diameter larger than the width of the field edge near the male screw side opening end of the screw hole.

[0007]

The field support member according to the present invention is attached to the concrete foundation by using screws or nails or by using an adhesive without using a hanging bolt or the like, and by using a snap connection (snap fit). It is fitted into the field by one-touch operation. Therefore, by attaching this field support member in close contact with the concrete base,
The space between the field edge and the concrete substrate can be very small. Also, the attachment of the field edge can be easily done by one-touch operation from one side using the snap fit.

If the field edge supporting member is composed of a first member mainly having a male screw portion and a second member having a locking portion, and these are screwed together to be integrated, the second member By the rotation operation, it is easy to adjust the distance between the field edge and the concrete foundation, and thus also the parallelism of the field edge. Particularly, if a rotary operation knob portion having a diameter larger than the width of the field edge is integrally formed near the male screw side opening end of the second member, the parallelism adjustment after the field edge is attached becomes easier.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing a state in which a field edge 2 is attached to a ceiling concrete foundation 1 using a field edge supporting member 3 according to an embodiment of the present invention, as seen in parallel to the longitudinal direction of the field edge 2,
FIG. 2 is a view of this from below. The field support member 3 is
It is a plastic molded body, and in this embodiment, it is composed of a first member 3a and a second member 3b.

As shown in FIG. 3, the first member 3a of the field edge supporting member 3 is composed of a male screw portion 32 and a square-shaped collar portion 31 integrally formed at the base end thereof. A screw hole 33 that vertically penetrates the corner of the collar portion 31 and the male screw portion 32 is machined, and by utilizing these screw holes 33, the first member 3a is
As shown in FIG. 5, the concrete base 1 is attached with screws 4 or nails in a state of being closely attached. You may attach using an adhesive agent, without using a screw and a nail.

As shown in FIG. 4, the second member 3b of the field edge supporting member 3 is mainly composed of a locking portion 35 in which a screw hole 36 to be screwed into the male screw portion 32 of the first member 3a is processed. . As shown in FIG. 1, the locking portion 35 is processed into an octagonal truncated pyramid, and the field edge 2 is fitted by snap fitting from the bottom surface 38 side. That is, field 2 is shown in FIG.
As shown in FIG. 5, a steel double bar or a single bar having a substantially U-shaped cross section, and hook portions 21 projecting inward are formed along both upper ends of the double bars or single bars. Is locked in the locking groove 39 at the upper end of the.

On the opening end side of the screw hole 36 of the second member 3b, a rotary operation knob portion 37 is integrally formed as a locking groove 39 with a predetermined gap. This knob part 3
7 is an octagonal plate shape, and as shown in FIG.
The octagon has a relationship in which the apex angle is deviated by exactly 22.5 degrees. As shown in FIG. 2, the diagonal dimension w2 of the knob portion 37 is made larger than the width w1 of the field edge 2.

The process of attaching the rim is as follows. First, the first member 3a of the field edge supporting member 3 is attached in a state of being closely attached to the ceiling concrete foundation 1, and the male screw portion 3
Drop 2 Next, the second member 3b is attached to the male screw portion 32.
Attach. At this time, the rotation operation may be performed by the knob portion 37 or the locking portion 35. By mounting the second member 3b, the height of the mounting position of the field edge is temporarily set.

After attaching the field edge support member 3 to the ceiling substrate in this manner, the field edge 2 is fitted from below. At this time, as shown in FIG. 2, by setting the side of the locking portion 35 of the second member 3b to be parallel to the long side of the field edge 2 to be fitted in advance, the field edge 2 can be relatively made. It can be snap-fitted by one-touch fitting with a weak pressing force. If it is necessary to further adjust the parallelism or the field edge mounting position after the field edge 2 is attached, it can be easily adjusted by rotating the rotary operation knob portion 37. At the rotation position of 45 ° each from the state of FIG. 2 in which the apex angle portion of the knob portion 37 just protrudes to the side of the field edge 2, the hook portion 21 of the field edge 2 and the locking portion 35 come into contact with each other and become stable. It becomes a state.

As described above, according to this embodiment, the field edge supporting member 3 made of a plastic molded body can be attached in close contact with the concrete base, and the field edge 2 can be easily attached to this by one-touch operation. Depending on the size of the support member 3, for example, the distance d from the surface of the concrete base 2 shown in FIG. 1 to the surface of the field edge 2 attached can be made extremely thin, about 20 mm or less. Further, if a plurality of types having different heights of the male screw 32 are prepared as the second member 3a, the distance d can be set arbitrarily.

The present invention is not limited to the above embodiment. For example, FIG. 5 shows another example of the second member 3b. In this example,
The locking portion 35 is a hexagonal frustum, and correspondingly, the rotary operation knob portion 37 is also a hexagonal plate. Further, as shown in FIG. 6, the locking portion 35 may be an octagonal frustum and the rotary operation knob portion 37 may have a disc shape. Although not shown in the drawing, the locking portion 35 may be a truncated cone.

Further, the screw hole 36 on the side of the second member 3b of the supporting member 3 can be used as a through hole. If the screw hole 36 is a through hole, it is possible to perform an operation of integrating the second member 3b and the first member 3a and attaching them to the concrete foundation 1 before attaching the first member 3a to the concrete foundation 1. . The male screw 32 is hollow from the tip to the flange 31 to prevent so-called "sink" at the time of plastic molding, and the length of the screw or nail for fixing the central portion of the flange 31 is set. It can be made equal to the length of the screw or nail fixing the periphery of the portion 31.

Further, although the parallelism and the mounting position can be adjusted after the field edge is mounted in the embodiment, if the position is sufficiently adjusted at the stage of coupling the second member 3b to the first member 3a, the field edge mounting is possible. There is little need for later adjustments. Therefore, the rotary operation knob portion 37 of the second member 3b can be eliminated. Furthermore, the first member 3a and the second member 3b may be combined with each other, and thus the male screw portion 32 and the screw hole 36 may be integrally formed into one plastic molded body without processing. Further, the field edge support member of the present invention may be made of reinforced plastic, ABS resin, or other plastic, or part or all of it may be made of metal or ceramic. Although the field edge mounting to the ceiling has been described in the embodiment, the field edge supporting member of the present invention is not limited to this, and is similarly applicable to a side wall and a floor.

[0019]

As described above, the field edge support member according to the present invention is attached to the concrete foundation by using a screw or the like without using a hanging bolt or the like, and the snap connection is used to perform a one-touch operation on the field edge. Can be fitted by a simple operation, and the space between the field edge and the concrete ground can be made extremely small by closely attaching the field edge support member to the concrete ground.
