In the upper diagram of FIG. 3, the rotating plate and the main body are parallel, and the arc portion of the rotating plate is in the slit. In this state, the perforated object indicated by the phantom line in the figure can move to the right of the main body through the rotating plate and the main body. A tube may be used as the main body.

After this movement, when the rotating plate is rotated clockwise and released, the rotating plate moves downward by the weight of the rotating plate, and the pin is positioned above the elongated hole. It becomes the state of.
In this state, the rotation of the rotating plate is prevented from the positional relationship with the slit, so that the object that has moved rightward is prevented from falling off from the main body. When removing the object from the main body, if the object is picked up and moved upward, the object can be turned and can be removed by the reverse of the procedure described above.
The gravity lock is provided to be fixedly provided on the upper side surface and the lower side surface of the tubular body, and the direction thereof is opposite to the attached column body fixture.

  Next, the gravity clamp 20 will be described. In the figure, 21 is a main opening / closing body, which is a curved member in plan view. Reference numeral 22 denotes a sub-opening / closing body, which is a curved member approximate to the main opening / closing body. One end of each of these open / close bodies is pivotally supported, and the other end opens and closes. Both ends of the main opening / closing body are bifurcated, and one end of a male screw 23 is pivotally supported at the lower bifurcated portion, and the other male screw projects through one end of the sub-opening / closing body, and a nut 24 is screwed into the protruding portion.

  Next, the use of the present invention will be described. First, the building frame structure used for the framework scaffold will be explained. FIG. 12 is a view showing a state of attachment to a torii type building frame used in connection with the present invention. In the figure, reference numeral 40 denotes a building frame having the following configuration. Reference numeral 41 denotes an upright column body having a predetermined length, and reference numeral 42 denotes a horizontal column body, which is a tube body fixed horizontally between the upper ends of a pair of upright column bodies. Reference numeral 43 denotes an attached column, which is a downward curved tube having a diameter smaller than that of the column, and its upper end is fixed to the lower surface of the horizontal column and the lower end is fixed to the side of the upright column. Reference numeral 44 denotes a connecting body, which is a short tube body, which is fixed between the attached column body and the upright column body. A horizontal reinforcing column 45 is a tube having an outer diameter comparable to that of the additional column, and is fixed between the pair of additional columns in the vicinity of the upper portion.

The above-mentioned torii-type building frames are used in large numbers by being connected vertically and horizontally at the construction site, but generally, the lower part of the upright column of the building frame is inserted and fixed to a fixed base metal fitting. A flat plate is fixed to the lower portion of the fixed base metal fitting, and a load applied to the building is transmitted to the ground via a floor plate or the like.
Gravity locks protrude vertically on the inner side surface of the upright columnar body, and in the overall illustration, an example using a spring-type gravity lock is shown. This gravity lock is for locking the brace, and the brace is arranged in an X shape when viewed from the front as shown in FIGS. 8 to 11, whereby the scaffolds are firmly connected and integrated. Become. Usually this is done continuously. A cloth plate 51 is attached between the horizontal columns of the building frame. The cloth plate is a metal plate having hook portions at both ends, and the hook portions engage with the horizontal column.

  The worker works on this cloth board, but requires an elevating means, and a staircase is provided for this purpose. However, in order to avoid projecting parts in plan view from the relationship of installation space, this torii type building frame is used for staircase installation using this width size difference using a wide width and a narrow width, The brace connection is difficult. That is, the brace is fixed by the gravity lock provided on the upright column, but due to the difference in width, the wide brace cannot be used as it is as the narrow brace. Some means of absorbing this dimensional difference is required, and for this reason the brace connection according to the invention was invented.

  The above is a known building frame and its subject, and the brace connection body for different width building frames of this invention is attached to a building frame as follows. This different-width building frame brace connector is used by being attached to a wide building frame. The attachment plate 6 is removed from the fixation plate 5 in the attachment column body fixture 4 described above, the curved portion of the fixation portion is applied to the side portion of the attachment column body 43, and sandwiched by the attachment plate 6. It fixes with a volt | bolt and a nut, and an attachment column body is pressed and hold | maintained by the attachment column body fixing tool by this. At this time, the horizontal reinforcing column body is located in contact with the horizontal reinforcing column body receiving portion 3. Further, the gravity lock protrudes toward the inside of the building frame.

  In addition, the above-mentioned gravity clamp is pressed and fixed in the same manner to the upright column body opposite to the brace connector mounting position, and the spring-type gravity lock protrudes inward from the building frame, and its vertical position is the brace connector. It is the same as Gravity Lock Rock. The preparation is now complete and the brace can be locked. The position of the brace locking position of the wide building frame is different from the position of the narrow brace locking position, but this is solved by the present invention.

That is, as shown in FIGS. 13 to 14, the gravity lock of the brace connection body of the present invention is located on the inner side than the upright column body position of the wide building frame, and this position is at the gravity lock position of the narrow building frame. equal. Therefore, the wide building frame and the narrow building frame can be connected and integrated, resulting in a state as shown in FIG. The wide building frame upright column on the side opposite to the attachment of the brace body has a different height so that the brace on the wide building frame side and the brace on the narrow building frame can be locked.
As described above, wide and narrow building frames can be used integrally.

  Although the present invention has been described above, the present invention is advantageous in that both the wide and narrow building frames can be used integrally by installing the same inside the wide building frame and providing the same brace mounting position as the narrow building frame. It is what has. Conventionally, since there is no such means, wide and narrow building frames are used independently, and it takes time and labor to set them. Also, pay attention to the installation position and direction of both building frames. Although it was necessary, in the present invention, both building frames can be integrated, and it becomes more convenient.

In the example, the horizontal reinforcing column body receiving portion is a U-shaped plate body, but may be a V-shaped or U-shaped receiving portion. Alternatively, a slightly thicker tube body may be used for the connection main body, the upper end thereof may be cut to a predetermined width and depth, and a U-shaped gap portion may be provided to serve as a receiving portion. In addition, in the example, the attached column body fixture is formed by a set of plate bodies having a curved portion at the tip thereof, but it may also be formed as a V shape or a U shape. Alternatively, the above-described gravity clamp configuration may be used. In addition, on the principle of the present invention, when the product of the present invention is mounted, the distance between the upright column body axis of the wide building frame and the connection body axis center of this product is equal to the width difference between the wide building frame and the narrow building frame. Become. The connecting body length is shorter than the upright column length of the building frame, and the lower end position of the connecting body is slightly higher than the lower end position of the building frame upright column when in use.
As described above, the present invention can provide a significant means for integrally using the different width building frame.
