Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention is applicable to anchor bolts for fixing anchor bolts to beam reinforcing bars, for example. Regarding the fixing device, in particular, it does not require welding work when fixing, and all operations can be done. This relates to equipment that allows a single worker to carry out the work.

0002

[Conventional technology]

For example, when securing anchor bolts used when constructing steel columns, Anchor bolts were welded and fixed to column reinforcing bars and beam reinforcing bars.

0003

[Problem that the idea aims to solve]

The conventional configuration described above has the following problems. First, tighten the anchor bolt. The work is complicated because welding is required when fixing the anchor bolt. One person is required to weld and fix the bolt while adjusting its position and level. This is a problem that is impossible with only one worker and requires two or more workers. There was a problem. In addition, welding may not be possible in the rain, and There was also the problem that this would have an adverse effect on column reinforcing bars and beam reinforcing bars.

0004 The present invention was developed based on these points, and its purpose is to One worker can easily place the anchor bolt in the desired position without any contact work. An object of the present invention is to provide an anchor bolt fixing device that can be fixed in place.

[0005]

[Means to solve the problem]

In order to achieve the above object, the anchor bolt fixing device according to the present invention is attached to reinforcing bars. A jig for installing multiple reinforcing bars that extends the attached bolts in the vertical direction. , Attach directly to the bolts of the above-mentioned multiple reinforcing bar attachment jigs or indirectly through beam materials. Anchor bolt mounting plate where the anchor bolt is set while being removed. It is characterized by having the following.

[0006]

[Effect]

When fixing an anchor bolt using the anchor bolt fixing device according to the present invention. In this case, first, attach a plurality of reinforcing bar attachment jigs to the reinforcing bars at arbitrary positions. this work , the bolts are extended vertically from the multiple reinforcing bar installation jigs installed. It will be placed in such a manner. Next, attach multiple bolts that extend vertically. Attach the anchor bolt mounting plate directly or indirectly via a beam. And what sets the anchor bolt on this anchor bolt mounting plate. It is.

[0007] In the case of this invention, when fixing the anchor bolt, welding work as in the conventional method is not required. It doesn't require any work. In addition, for level adjustment, it is for anchor bolt installation. When installing the plate, all you have to do is adjust the mounting position for multiple bolts. It's easy.

[0008]

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. Figure 1 shows this example. Four anchor bolts are fixed using the anchor bolt fixing device by FIG. First, there is a reinforcing bar attachment jig 1, and this reinforcing bar attachment jig 1 is shown in Figure 2. As shown, a pair of holding plates 3, 3 formed by bending a flat plate and a fully threaded bolt (bolt) that fastens and fixes these pair of holding plates 3, 3. 5 and a pair of nuts 7, 7. Reinforcing bars with this configuration As shown in FIG. 3, the attachment jig 1 is attached to the reinforcing bars 9 at four locations.

[0009] The four fully threaded bolts 5 placed by the reinforcing bar installation jig 1 are extended upward. Install the horizontal beams 11, 11 using the tops of these four fully threaded bolts 5. Let's go. This cross beam material 11 has two elongated holes 13 and 13, as shown in FIGS. 3 and 4. It is prepared. The fully threaded bolts 5 are passed through these elongated holes 13, and the upper and lower It is fixed by tightening nuts 15, 15. At that time, first, the lower Adjust the level by appropriately rotating the nut 15. After completing the level adjustment, The cross beam members 11, 11 are placed on top of it. Then, screw the nut 15 on top of it. It is fixed in place.

0010 Next, the anchor bolt mounting plate 17 is placed on the above two horizontal beam members 11, 11. to be fixed. This anchor bolt mounting plate 17 has elongated holes at four locations. 19 are formed, and these four elongated holes 19 and the four horizontal beams 11, 11 are formed. Using the elongated hole 13, attach the anchor bolt mounting plate with the bolt 21 and nut 23. The rate 17 is fixed on the cross beam members 11, 11. Anchor bolt mounting plate 1 After fixing 7, set the four anchor bolts 25 there.

[0011] According to this embodiment, the following effects can be achieved. First, the anchor When fixing the bolt 25, there is no need for welding work as in the conventional method, and therefore, Problems when welding work is required, specifically, the need for many welders, All problems such as difficult work, dependence on weather, and negative impact on reinforcing steel have been completely eliminated. It can be resolved by

0012 In addition, the work is extremely simple, so one worker can do all the work. Ru. For level adjustment, the nut 15 is screwed into the fully threaded bolt 5. This can be easily done by adjusting the position.

[0013] Note that the present invention is not limited to the above embodiment. For example, the above embodiment Now, attach the anchor bolt mounting plate 17 via the two cross beams 11, 11, Although it was fixed to the fully threaded bolt 5 of the book, it is also possible to fix it directly to the fully threaded bolt 5. good. In addition, the number, shape, etc. of each member are not limited to those shown in the drawings, and may be determined arbitrarily. Ru.

[0014]

[Effect of the idea]

As detailed above, according to the anchor bolt fixing device of the present invention, the anchor When fixing bolts, there is no need for welding like in the past, and it is much easier. Therefore, problems caused by welding work can be eliminated. Also, level tone The work is extremely simple, as it is easy to set up, and all work is done by one worker. be able to.
