Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a set frame fixing device for supporting an ALC reinforcing material. More specifically, when molding a panel made of plastic material, fixing of a set frame is used to suspend a support set rod that supports a reinforcing material within a formwork from the bottom plate of the formwork onto a side plate of the formwork. It's about equipment.

BACKGROUND TECHNOLOGY Conventionally, in order to achieve a predetermined positional accuracy when fixing a set frame onto a side plate for suspending a set rod supporting a plastic material reinforcing material onto a form bottom plate,
As shown in FIG. 1, after positioning each set frame 4 in the form width direction by visual inspection, the bolts 7 are tightened and fixed to the side plate 2 by hand using the tightening tool 8 shown in FIG. It was a device.

Problems to be Solved by the Invention As described above, with the conventional apparatus, fine adjustment takes time and the positioning accuracy is not always satisfactory.

The object of the present invention is to provide a setting frame fixing device that reduces the time required for such fine adjustment work and improves positioning accuracy.

Means for Solving the Problems The present invention has been improved so that a reference plate 12 with an insertion groove is placed on the side plate 2 of the formwork, and one end of the set frame 4 is inserted into this, thereby achieving the above purpose. This is what we are trying to achieve.

The gist of the present invention is that when the setting frame 4 for fixing the reinforcing material support setting rod 5 is fixed on the side plate 2 of the formwork, at least one end of the setting frame 4 is attached to the reference plate 1.
2, a reference plate 12 provided with an insertion groove 22 is installed on at least one side of the formwork side plate 2, and the reference plate 12
The set frame fixing device for supporting an ALC reinforcing material is characterized in that the frame is fixed by a fixed support frame column 23.

Example The present invention will be explained below by way of an example.

Fig. 1 shows an overall view of the set frame fixing device according to the present invention, enlarged views of parts a and b shown in Fig. 1 are shown in Figs. 2 and 3, and a sectional view taken along line A-A is shown in Fig. 4. ,c
An enlarged view of the section is shown in Fig. 5.

When suspending and fixing the above-mentioned plastic material, for example, the reinforcing material of ALC (hereinafter referred to as reinforcing bar 6) on the formwork bottom plate 1, set rods inserted into the reinforcing bar as shown in Fig. 4 are used. 5. Furthermore, the setting frame 4 for fixing the setting rod is positioned and fixed via the form side plate 2. At this time, as shown in FIGS. 2 and 5, on one of the side plates, a reference plate 12 having an insertion groove 22 with a V-groove guide is provided between the 4 ends of the set frame and the form frame side plate 2. On the other hand, during long-term use, this formwork side plate 2 is subject to deformation due to external forces due to handling, foaming, hardening and expansion of the ALC mortar injected into the formwork, etc.
In order to isolate the set frame 4 from displacement caused by the deformation of the formwork side plate 2 and the foaming, hardening and expansion of the injected ALC mortar, a bearing 18 is laid under the reference plate 12, and a bearing 18 is installed on the other side of the side plate to insulate the set frame 4 from movement and displacement caused by the foaming, hardening and expansion of the injected ALC mortar. The structure has a bearing 18 installed on the lower side, and also takes into account the case where the movement displacement is large.
In order to fix the standard of the V-groove plate, tie rods 26 are set and reinforced on the fixed support pedestal columns 23.

Note that the short side direction (first side direction) of this reference plate 12 is
B direction) is fixed by inserting the insertion guide pin 15 into the hole of the reference plate 12 on the formwork fixed end plate 3 side, and on the movable end plate 9 side, as shown in Fig. 2. For the moving side reference frame 1 fixed on the formwork bottom plate 1 as shown in Fig.
An insertion guide pin 20 driven by a toggle clamp 19 installed on the reference plate 12
It is positioned and fixed by inserting it into the hole. As a result, the setting frame 4 is positioned in the short side direction.

Further, the positioning of the set frame 4 in the long side direction (direction c in Figure 1) is carried out using two long side positioning guide jigs 13 only for the side ends of the fixed end plate 3, as shown in Figure 2. This is done by welding and fixing on the frame side plates 2 and inserting the 4 ends of the setting frame between them. Usually, panels have various lengths, so the positioning of the set frame in the long side direction at other positions is done visually.

Furthermore, as a measure to prevent the setting frame 4 from floating due to mortar foaming, as shown in FIG.
This is done by manually rotating the locking pin downward through 90 degrees so that the tip of the locking pin fits into the raised stopper 14 on the upper edge of the side plate 2. Furthermore, as described above, the set frame 4 is isolated by the slide bearing 18 against movement of the formwork side plate 2 in the short side direction (direction B in FIG. 1) due to mortar foaming, hardening and expansion.

Next, how to use the device according to the present invention for installing the reference plate 12 on the side plate 2 of the formwork will be explained.

First, regarding the reference plate 12, the fixed end plate 3
As shown in FIG. 2, by raising the fixed end plate 3 in the direction shown by the arrow, the insertion guide pin 15 is inserted into the hole made in the reference plate, thereby positioning and fixing the reference plate. Next, on the movable end plate 9 side, as shown in FIG.
Insert into hole 2 and position and fix. The ALC reinforcing bar 6 is installed in the insertion groove 22 of the reference plate 12 which is positioned and fixed in this manner, and the lower ends of the plurality of set frames 4 are inserted along the V-groove guide. At this time, the set frame at the side end of the fixed end plate 3 is inserted between the short side positioning guides 13. Next, insert the lock handle 17 into the hole with the set frame slide bearing 17, and lift up the stopper 14.
After reaching the bottom of the lock handle 17
By rotating the frame 4 downward by 90 degrees, the setting frame 4 is locked onto the side plate 2 of the formwork. Next, since the V-groove plate is long, in order to further fix the reference between them, a tie rod is set on the fixed support frame pillar 23 fixed at a predetermined position on the floor, and it is fixed by slicing it in a position where it will not hit the setting frame. Ru.

Note that this reference plate 12 may be installed on both sides of the formwork side plate 2, but as shown in FIG. 4, it may be installed only on one side of the side plate, and the slide base 16 structure may be provided on the other side plate. . Further, as the guide groove, a U groove or the like may be considered in addition to the V groove.

Effects of the invention Conventionally, the positioning work of the ALC reinforcing material 6 within the formwork was performed by finely adjusting the tightening bolts 7 for each set frame 4 as shown in Fig. 5, so the adjustment work was considerably reduced. However, according to the present invention, positioning in the width direction is possible simply by inserting the four ends of the set frame into the reference plate 12, which significantly improves the adjustment and fixation of the set frame. Effects such as shortening of working time and improvement of positioning accuracy can be obtained.
