Description

[Detailed description of the invention] The present invention relates to a channel fixing device, and more specifically, to a formwork (channel) used for tightening or fixing interior partition members or decorative members in structures such as buildings. The present invention relates to a channel fixture for connecting to a foundation channel.

More specifically, the interior partitioning members in structures such as buildings mentioned above are, for example, partition walls, hatches installed on the thresholds (rails) of partitioning doors and shoji, or ceilings, etc., and the decorative members include: For example, this refers to decorative boards for ceilings, floors, or construction wall surfaces such as concrete that are inevitably exposed during construction, especially hanger boards for kitchens or decorative boards for stage construction. This invention relates to a channel fixing device for connecting a foundation channel to a foundation channel.

Conventionally, for ceiling structures used as interior members in structures such as buildings, as shown in the first diagram, a foundation channel 2' is suspended at a predetermined height using stud bolts 1', and the foundation channel 2' is The mounting channel 3' of the ceiling material can be welded (see figure a), or b can be connected via a tensioning bolt 5' with a holding frame 4' as shown in figure c.
As shown in the figure, a clip 6' made of an elastic material such as wire was used to connect the two. In the case of the above-mentioned fixing devices, it is not possible to adjust the vertical tensioning force of the channel with respect to the foundation channel. For example, in the case shown in b, the tension is applied only in the horizontal direction, and in the case shown in c, even if there is a tensioning force in the vertical direction, that tension is within the elastic limit of the clip. It was not versatile.

The present invention not only simplifies the installation operation when connecting the foundation channel and the channel, and also allows the tensioning force between the two to be adjusted arbitrarily, but also allows the installation of the channel for installing floor materials or ceiling hatches, etc., as described above. As when installing in the foundation channel,
Even if the work space for installation is extremely narrow,
Furthermore, it is an object of the present invention to provide a channel fixing device that can be tightened using a special thumbscrew devised for the purpose of the present invention and that allows the use of an automatic screwdriver (such as a screwdriver).

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

FIG. 2 and FIG. 2-3 showing a line cross section.
The figure is a cross-sectional view of the main part showing the state in which the channel is tightened to the base channel using the channel fixing device of the present invention, and each member indicated by a drawing reference number in both figures and the mutual relationship between each member. The explanation is as follows.

Reference numeral 1 designates a foundation channel that is constructed at a predetermined position using stud bolts (not shown), and 2 designates a channel that is connected to the foundation channel 1.
Reference numeral 3 denotes a channel fixing device of the present invention, and this channel fixing device 3 is composed of two straddling legs 4 and 5 and a shoulder plate 6 connecting both of the straddling legs. A straddle groove C is formed between the straddle legs 4 and 5, which is slightly larger in width than the width of the channel 2, which will be described in detail later. Further, two locking pieces 7 and 8 are formed on the side surface of each of the straddle legs 4 and 5 on the straddle groove C side. Further, a thumbscrew 9 with a groove is provided approximately at the center of the shoulder plate 6.

Details of each of the above members will be explained below.

Both the foundation channel 1 and the channel 2 are formed with a U-shaped cross section, and when connecting both channels, the upper flange 21 of the channel 2 is crossed in a cross shape to the lower flange 12 of the foundation channel 1. It is firmly fixed by a fixing device 3 of the invention.

The two straddle legs 4 and 5 are each formed symmetrically.
Since it is sufficient to explain the above, explanations regarding the other straddle legs 5 will be omitted. The straddle legs 4 and 5 are formed to have an L-shaped cross section, and are spaced apart by a predetermined width h from the surfaces of the lower legs 41 and 51 so that the engaging pieces 7 extend their lower end surfaces substantially parallel to the lower legs 41 and 51, respectively. 5
It is planted and fixed on 2 in a direction perpendicular to this. Further, another engaging piece 8 is planted and fixed at the upper end of the upstanding legs 42, 52, the upper end surface of which is close to the above-mentioned shoulder plate 6, and which extends in a direction perpendicular to the plane of the upstanding legs 42, 52. As long as the above-mentioned attachment pieces 7 and 8 satisfy the above-mentioned installation conditions, they may be formed by connecting them, for example, they may be structurally formed integrally from the same material, or they may be formed by bending them. It may be formed by processing or welding. Also, the engaging piece 8 is the shoulder plate 6.
This can be omitted by forming the shape into a shape that retains the function of the engaging piece.

The shoulder plate 6 is fixed to the heads of the both straddle legs 4 and 5, and a straddle groove C having approximately the same width as the flange width H of the foundation channel 1 described above is formed between both the straddle legs. are connected like this. Further, a screw hole 61 for attaching a grooved butterfly screw 9 is provided approximately at the center of the shoulder plate 6. The double straddle legs 4 and 5, the shoulder plate 6, and each engagement piece 7, 8 shown in this embodiment are integrally formed by die casting, and the double straddle legs 4 and 5, which require particularly rigidity, are integrally formed by die casting. , 5 and the shoulder plate 6, reinforcing ribs 10 as shown in FIG. 2 and FIG. .

The grooved butterfly screw 9 is screwed into the screw hole 61 of the shoulder plate 6, and as shown in FIGS. By pressing the upper flange 11 of the foundation channel 1 which is overlapped with the foundation channel 21, a function is provided to tighten the foundation channel 1 and the channel 2 together.

The grooved butterfly screw 9 is particularly suitable for the fixture 3 of the present invention.
The details are shown in FIG. A butterfly-shaped gripping portion 92 is formed, and a locking groove 93 for a screwdriver or the like is provided on the head surface of the screw rod 91. Note that the butterfly-shaped gripping portion 92 includes:
A bowl-shaped space 94 is formed for insertion of the tip of a fastener such as a driver (not shown). In the case of manufacturing the butterfly screw 9 with a locking groove, the screw rod 91 with the locking groove 93 and the butterfly-shaped gripping part with the bowl-shaped space 94 are manufactured separately, and then both are integrated by a press or the like. Manufactured by compression molding. The grooved butterfly screw 9 can be used for both ceiling and floor mounting in different mounting directions.

The mode of use and operation of the present invention will be explained as follows.

When connecting and fixing foundation channel 1 and channel 2 in an intersecting manner, first,
The shoulder plate 6 is mounted on the upper flange 11 so that the two straddling legs 4 and 5 straddle the upper and lower flanges. At this time, the grooved butterfly screw 9 is sufficiently loosened, and the upper flange 21 of the channel 2 connected between the lower flange 12 and both lower legs 41 and 51 is
A gap larger than the wall thickness is formed.

Next, when the upper flange 21 of the channel 2 is inserted into the gap, the channel 2 is suspended by the two lower legs 41 and 51, and even if the holding force for working is removed in this state, the channel 2 will not fall. After the channel 2 crosses the foundation channel 1 in a cross shape and is suspended, if the grooved thumbscrew 9 is compressed, the lower flange 12 of the foundation channel 1 and the upper flange 21 of the channel 2 are connected. is forcibly crimped,
Both channels are tightly secured together. When compressing the butterfly screw 9 with the groove, the butterfly-shaped gripping portion 92 is manually compressed to a certain extent to determine the mounting position of the channel 2, and then the groove 93 is tightened using an automatic screw tightener. It is possible to connect both channels with a predetermined tensioning force via. In addition, the respective end faces of the main body 13 of the foundation channel 1 and the upper and lower flanges 11 and 12 are guided and positioned by the engaging pieces 7 and 8 formed on the supporting legs 42 and 52, so that there is no backlash. Never get stuck,
In the end, both channels are extremely firmly connected.

The predetermined width h between the lower legs 41, 51 and the engagement piece 7 can be applied to the thickness of the upper flange 21 of the channel 2 to the maximum extent possible, and the channel fixture 3 itself is sufficiently loosened when installing the channel 2. It also has a function to prevent blurring from side to side.

FIG. 6 is a mock diagram showing an example of the use of the present invention in the case where the channel 2 used for installing the flooring material f is firmly fixed to the foundation channel 1.
Even when the work space is narrow and the work area cannot be seen directly, as in this usage example, the channel fixing device of the present invention can tighten both channels by simply compressing the grooved thumbscrew 9. It is something that can be fixed.

With the above configuration, the present invention can be used not only to achieve the purpose of lightweight structures accompanying the increase in the height of buildings by substituting a channel structure for interior interior members of conventional reinforcing members, but also as a soundproofing and heat insulating material. It is extremely useful as a fixing device for installation channels, system ceilings, and interior channels that do not require braces.
