As long as it is attached to the column base, there is no difficulty in attaching each stand-mounted skier, and there is an advantage that the attaching work is simple.

However, in actual assembly work of steel structures, there are various sizes of column bases to be used, and as the size of the column bases changes, brackets attached to three sides of the joint block are The position also changes along the width direction of the column base. However, since the conventional pedestal-equipped Scoya mount is fixed at a predetermined position on each piece of the pedestal body, there is a misalignment between the ruler surface 125 of the pedestal-equipped Scoya and the measurement surface 127 of the bracket, making distance measurement difficult. There is a problem that the process becomes extremely complicated.

The present invention has been made based on the above points, and an object of the present invention is to provide a pedestal-mounted skier that can easily measure the distance between the pedestal-mounted skier and the bracket, corresponding to pillar bases of various sizes. The objective is to provide a mounting frame for.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. 1 to 7. Fig. 1 is a perspective view showing a state in which the pedestal scoyer is attached to the mounting frame for the pedestal scoyer according to the present embodiment, Fig. 2 is a front view of the same, and Fig. 3 is the II of Fig. 2.
4 is a sectional view taken along IV-IV in FIG. 2.

The frame body 1 is an L-shaped extension of the plates 3 and 5, and is arranged so as to sandwich one corner of the column base 7. On the opposite side of the plate 3 of the gantry main body 1 across the column base 7, a movable plate 9 is arranged parallel to the plate 3 and movable forward and backward with respect to the plate 3. As shown in FIGS. 3 and 4, the movable plate 9 has its end fitted into the notch 11 of the plate body 5, and moves within the range of the notch 11.

Regarding the structure for moving the movable plate 9, first, a ball screw 13 is placed in the center of the notch 11, and this ball screw 13 is fixed to a handle 15. Therefore, by rotating the handle 15 in an appropriate direction, the handle 15 is rotated in the same direction. On the other hand, the plate body 5 of the moving plate 9
A ball nut portion 17 is formed at the side end and approximately in the center, and this ball nut portion 17 is screwed into the ball screw 13. Therefore, by rotating the handle 15 to rotate the ball screw 13,
The moving plate 9 moves in the direction of arrow A.

Furthermore, the movable plate 9 is guided by a pair of guide shafts 19, 19 installed on both sides of the plate body 5. The structure for moving the moving plate 9 is as follows:
The structure is not limited to the above structure. For example, the moving plate 9
may be always urged in the direction of the column base 7 by a spring, or the movable plate 9 may be moved by a clamp mechanism using a "lever".

Further, the structure for fixing the movable plate 9 to the column base 7 after being moved is not limited to the above structure. For example, it may be fixed to the column base 7 with a magnet, or the movable plate 9 and the plate body 5 may be fixed to the column base 7 with a chain. A pair of fixing pins 21, 21 are provided protruding from the plate body 3, and these pair of fixing pins 21, 21 come into contact with one side of the column base 7. Furthermore, fixing pins 23 are provided protruding from the plate body 5 at four locations, and these four fixing pins 23 abut against the upper surface of the column base 7. Furthermore, a pair of fixing pins 25, 25 are provided on the movable plate 9 in a protruding manner, and abut on the other side surface of the column base 7.

On the side of the plates 3 and 5 and the movable plate 9 opposite to the column leg 7, a skiya mounting base 27 with a stand is provided. This Scoya mount 27 is made of iron and has a recess 29 formed therein. The stand 33 of the stand-mounted skier 31 fits into this recess 29. The Scoya mount 27 is configured to be movable along the column base 7 in its width direction. In other words, the lower part of the base mount 27 disposed on the upper surface of the plate 5 extends into the notch 11 of the plate 5 to form a pair of slide metals 34, 34 there. By fitting into a pair of guide shafts 19, 19 installed at both ends of the plate body 5, the plate body 5 is supported so as to be movable in the width direction along the column base 7.

[0020] Similarly, the lower part of the base-mounted skier mount 27 disposed on the upper surface of the plate body 3 and the movable plate 9 passes through the notch 36 formed in the plate body 3 and the movable plate 9. A pair of slide metals 38, 3 are inserted here.
8 is formed, and is supported so as to be movable along the column base 7 in its width direction by fitting into a pair of guide shafts 40, 40 installed at both ends of the plate body 3 and the movable plate 9.

The above-mentioned scooper with a stand 31 has a structure as shown in FIG. That is, from the base 33, a vertical plate 35 extending vertically from one end of the base 33, and a reinforcing plate 37 provided between the back side of the vertical plate 35 and the other end of the base 33. It has a generally right triangular shape as a whole. Further, each of the above members is made of aluminum in order to reduce the weight.

The base 33 has its bottom surface as a reference surface 39, and the vertical plate 35 has its front surface as a ruler surface 41. Further, the front side and both sides of the stand 33 are recessed in an arc shape, and serve as a gripping part 43. A magnet holder mounting hole 44 is drilled on the front side of the stand 33 from the bottom side, and inside this magnet holder mounting hole 44,
A magnet holder 45 is attached.

The magnet holder 45 has a box shape, and its suction surface 47 is flush with the reference surface 39 of the stand 33. Further, a switching lever 49 is attached to the magnet holder 45.
The magnetic force of the attraction surface 47 is turned on and off by the switching operation. Further, the platform 33 at the position of the switching lever 49 is formed with a recess to ensure operability of the switching lever 49.

As already mentioned, the stand-mounted skier 31 is made of aluminum and has the characteristic of being lightweight. However, since it is made of aluminum, its surface is soft and it is susceptible to damage during use. There is a problem in that accuracy decreases due to wear and tear. Therefore, the entire surface of the table-mounted skier 31 is subjected to surface hardening treatment. Specifically, aluminum alloy AC4C-V virgin material (JIS H5202-1971) is used as the material, and a hard coating is formed on the surface by an anodizing method.

The operation will be explained based on the above configuration. First, the joint block 51 is joined to the column base 7 by welding. Brackets 53 and 5 are provided on three sides of this joint block 51.
5. Work to install 57. Therefore, a mounting frame for a skier with a stand according to this embodiment is attached to the column base 7. That is, the gantry main body 1 is placed on the outer periphery of the column base 7, and the handle 15 is rotated to bring the movable plate 9 close to the column base 7 to clamp it. This fixes the pedestal to the column base 7.

Next, the stand 33 of the stand-mounted skier 31 is placed in the recess 29 of the stand-mounted skier mount 27 of the plates 3 and 5 and the movable plate 9.
mate. Then, the switching lever 49 of the magnet holder 45 is operated to turn on the attraction surface 47. As a result, the pedestal scoyer 31 is moved to the pedestal scoyer mount 27.
Fixed. Next, the pedestal mount 27 is moved along the column base in its width direction. This operation is performed manually, for example, by using the Scoya mounting base 27 on the top surface of the plate body 5.
is held by the guide shaft 19 via the slide metal 34, so by holding and sliding it by hand, it is slid and stopped at an arbitrary position. As for how to use it, for example, as shown in Figure 7, if we assume that the size of the column base is changed from a small one indicated by C in the figure to a large one indicated by D, In the case of C, the position of the pedestal mount 27 can be at the position c in the figure, but if it is a large one, it is difficult to measure at the position c, so the bracket mounting position of the large column base D (d in the figure) is difficult. Slide the mount 27 of the pedestal scoyer to the point shown by ) so that the ruler surface 41 of the pedestal scoyer and the measurement surface 59 of the bracket match. This makes it easy to measure the distance between them.

The other plate bodies 3 and the pedestal-mounted skier mount 27 on the upper surface of the movable plate 9 are also moved in the same manner. After that, 3
Brackets 53 are placed on three sides of the joint block while ensuring parallelism using the ruler surface 41 of the two pedestal scoya 31.
Install 55 and 57 respectively. According to this embodiment, the following effects can be achieved.

Since the Scoya mount 27 is movably attached to the column base 7 in its width direction, the column base 7
Regardless of the size of the pedestal, the mount 27 can be slid to the position where the bracket of the column base is attached, and the ruler surface of the pedestal can be matched with the measurement surface of the bracket, making it easy to measure the distance between the two. It is something that can be done.

It should be noted that the present invention is not limited to the above embodiments. In other words, there are various means for sliding the Scoya mount 27 with a base, such as guiding the Scoya mount 27 with a dovetail groove, using a feeding mechanism using a ball screw and a ball nut, and moving the mount 27 with a handle. Alternatively, it may be driven by an electric motor.

[0030] Furthermore, various configurations of the stand-mounted skier mount 27 are conceivable. That is, a groove 61 is formed in the stand-mounted skier mount 27 shown in FIG. 8, and a stopper 63 is provided in the groove 61 in a protruding manner. When installing the stand-mounted skier 31, the stand 33 is fitted into the groove 61 from one side, and one end of the stand 33 is brought into contact with the stopper 53 to determine its position.

Next, what is shown in FIG.
This is an example of using a type that does not use a magnetic holder.
4 with the stand 33 of the stand-equipped Scoya 31 fitted to 1.
It is fixed with two fixing bolts 73. Next, in the one shown in FIG. 10, a concave portion 81 is formed in the base 33 of the base-equipped skier 31, and a corresponding convex portion 83 is provided protruding from the base-equipped skier mount 27.

[0032] Also, in the above embodiment, the stand 33 of the stand-equipped skier 31
By appropriately setting the "fit" between the pedestal and the recess 29 of the pedestal scoyer mount 27, even the pedestal scoyer 31 without a magnetic holder may have a structure that can be fixed. Further, in the above embodiment, the plates 3 and 5 are integrated into L.
Although a letter-shaped member is used, this may be constructed as a separate body. At this time, the plate body 3 may be made to be able to move toward and away from the side surface of the column base 7 in the same way as the movable plate 9. In the case of the above embodiment, the movable plate has a structure in which the end portion is fitted into the plate body, but it may be attached in contact with the plate body or apart from the plate body.

[0033] Also, the magnetic holder 4 is attached to the table-mounted skier 31.
5 is built in, but it may be built in the Skoya mounting base 27 side. In addition, it can be similarly applied when attaching the pedestal scoyer 31 to one or two sides, and in that case, a pedestal scoyer mount can be provided on any one or two of the three pieces. It will be done.

Further, the structure of the mounting mechanism may be such that a pin and a hole into which the pin is fitted are provided between the base 33 of the pedestal scoyer 31 and the pedestal scoyer mount 27, and the two are fitted into each other.

[0035]

[Effects of the Invention] As described in detail above, according to the pedestal-equipped scoyer mounting frame according to the present invention, the pedestal-equipped scoyer mount is attached so as to be movable in the width direction along the column base.
Regardless of the size of the column base, the pedestal-mounted Scoya mount can be slid to the bracket mounting position on the column base, and the measurement surface of the pedestal-mounted Scoya and the measurement position of the bracket match, making it easy to measure the distance between the two. It is something that can be done.
