Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention uses a supporting metal fitting or another groove of grooved steel for preliminarily attaching to the grooved steel to support the grooved edge when fixing the edge of the grooved steel to the grooved steel with a lip. Then, it relates to a metal fitting which can be attached to the channel steel.

[0002]

[Prior art]

 It has been known to attach metal fittings to a channel steel lip without using special fasteners. That is, conventionally, a substrate made of a metal plate is doubled at both ends thereof to form a groove, and the groove is tightly fitted and fixed to the lip to be fixed.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional mounting structure, in order to double the both ends of the board, the metal plate must be welded and doubled, and moreover, the groove width is accurate to hold it only by fitting. There is a drawback that it needs to be accurate to some extent and that the overall cost is high. In addition, in order to fit the groove in such a manner, the groove and the lip must be positioned relative to each other, and there is a drawback that the mounting work requires much time. In particular, if it is not necessary to finally fix the metal fittings, but it is sufficient to temporarily attach the metal fittings, price and speed are required rather than the mounting strength, and the conventional ones cannot satisfy such a request. Didn't come

An object of the present invention is to provide an inexpensive metal fitting that can be quickly mounted in the groove of the channel steel.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a metal fitting for attaching to a lip channel steel, and a pair of sides that are smaller than the width between the lips for lateral insertion into the lips, Similarly, a substrate having another pair of sides that are larger than the width between the lips for abutting against the back face of the lip, and a web back face of the channel steel and the substrate with the substrate abutting against the lip in this manner. It is characterized by comprising a spring provided on the back surface of the substrate for compressing between them.

In the above, it is conceivable that a bolt for fixing a member supporting via the substrate is provided on the surface of the substrate in a protruding manner.

Further, it is conceivable that the pair of sides, which are smaller than the width between the lips, serve as cut-off portions in which the corner portions of the rectangular substrate facing each other are cut off in an inclined manner.

[0008]

[Action]

 According to the above configuration, with the spring on the back side, the end portion having a width smaller than the width between the lips is along the lips so that the direction perpendicular to the insertion direction after being inserted into the groove It can be easily attached by rotating it away.

[0009]

【Example】

FIG. 2 shows the whole of the mounting metal fitting of the present invention. In the figure, (1) is a substrate made of a metal plate, both ends of which in the left-right direction are both bent in the same side face in an inclined shape. It is bent to form an abutting end portion (2) (2) on the rear surface side of the lip of this invention. A mounting bolt (3) for mounting another member so as to project from the central portion of the substrate (1) is provided on the side surface of the contact end portion (2) (2) on the folding direction side. It is firmly fixed together. On the other hand, on the side surface opposite to the bolt (3), a torsion coil spring (5) having a conical shape as a whole is fixed at the end of the cone having a small cross section, and the torsion coil spring (5) is connected to the bolt (3). Project in the opposite direction. The width l ₁ of the sides (4) and (4) of the tips of the abutting ends (2) and (2) is as shown in FIG. 3 between the tips of the lips (7) and (7) of the channel steel (6). It is larger than the width L of. Further, as shown in FIG. 3, the corner portion of the substrate (1) is cut off at an angle of 45 degrees, and the width l ₂ between the cut-off inclined sides (8) and (8) is the lip (7). It is smaller than the width L between the intervals (7).

Next, the method of attaching the metal fittings (9) will be described. First, as shown in FIG. 3, the edges of the cut-off sides (8) (8) cut obliquely are the lips (7). Fit the gap between the lips (7) and (7) so that they are along the same direction as (7), and then push it inward. At this time, the length from the tip of the spring (5) to the tip of the abutting end (2) is larger than the length from the back surface of the lip (7) to the back surface of the channel steel web (11). The tip of this spring (5) is pressed against the back surface of the web (11) until it is compressed, and the contact end (2) is pushed further inward than the back surface of the lip (7). When rotated about 45 degrees in this state, the metal fitting (9) becomes almost perpendicular to the channel steel (6) as shown by the chain double-dashed line in FIG. It is held by elastic force.

The holding of the metal fitting (9) by the spring (5) is temporary attachment, and FIG. 1 shows a case in which a furring strip for attaching a gypsum board is further attached. The furring (12) is made of square timber, but the furring (12) has a bolt hole (13) formed, and the fitting (9) is temporarily attached as described above. When the bolt (3) is inserted into the bolt hole (13) and the nut (14) screwed on the opposite side is tightened, the substrate (1) is strongly pressed against the back surface of the lip (7), It will be securely held. Then, two gypsum boards (15) as shown in the figure are fixed by nailing or the like to the side surface of the furring strip (12) thus attached. Of course, the metal fitting (9) of the present invention can be applied not only to the attachment of the furring strip (12) and the gypsum board (15) but also to other things.

Further, in the above description, the coil spring (5) may be replaced with a leaf spring.

[0013]

As described above, according to the present invention, the substrate is aligned so that it can be inserted between the lips of the channel steel, the spring is slightly compressed, and then the There is an effect that the mounting can be done quickly by rotating in a direction perpendicular to the pushing direction and separating it, and the mounting can be performed easily and in a short time. Moreover, since it is only necessary to attach an inexpensive spring to the back surface of the base plate, it is not necessary to double weld the metal plates and finish the grooves between the metal plates with high precision as in the conventional case. Therefore, the effect that the processing cost can be reduced can be obtained. Furthermore, since it is simply pushed in and rotated as described above, there is an effect that a large force is not required and work can be performed without using a special tool.
