DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor bolt holding device for accurately and stably holding anchor bolts when forming various anchor bolt embedded concrete bodies such as building members.

[0002]

2. Description of the Related Art An anchor bolt is protruded from an outer surface of a concrete body for connecting various concrete bodies installed on a foundation portion of a building or the like or between other members. It is configured to be.

[0003] The formation of a concrete body in this way is performed by pouring concrete into a formwork assembled into a predetermined shape and solidifying the concrete.

FIG. 5 shows an example of such a formwork, and shows an example of a formwork forming a member 100 for constructing the foundation of a building. As shown in the drawing, the mold 10 is installed on a production bed 20 constituting a frame portion on the lower surface side, and concrete is poured into the inside of the mold 10 and solidified to form a hatched portion in the figure. The concrete body 100 is formed on the concrete.

[0005] The anchor bolts 12 are connected to the form 1
A through hole is made in the side wall of No. 0, and the hole is made to penetrate the hole in advance, and concrete is poured in that state and solidified. As a result, the anchor bolt 12 is buried in the concrete body 100 by a predetermined length, and the other portion projects outward.

[0006]

However, in the formation of a concrete body in which the anchor bolts 12 are buried as in the above-mentioned prior art, a device for stably holding the anchor bolts 12 has not been used. . Therefore, in order to form the anchor bolt 12 so as to project substantially perpendicularly to the outer surface of the concrete body when the concrete body is completed, it is necessary to stably hold the anchor bolt 12 until the concrete body solidifies. Although it must be kept, it is difficult to stably hold the anchor bolt in a state where it penetrates the side wall of the formwork.

That is, the diameter of the through hole is determined by taking the diameter of the anchor bolt 12 in consideration of the easy removal of the solidified form.
Is relatively large, it is difficult to hold the anchor bolt 12 substantially horizontally with respect to the production bed 20.

Further, after the anchor bolts 12 are passed through the formwork 10, it must be securely held until the concrete is solidified so that it does not shift or fall off due to impact until the concrete is solidified. Conventionally, such measures have not been taken.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to stabilize an anchor bolt on a mold from before the concrete is poured into the mold until solidification after the casting. An object of the present invention is to provide an anchor bolt holding device at the time of concrete formation which can be held by holding.

[0010]

In order to achieve the above object, an anchor bolt holding device for forming concrete according to the present invention is provided with a hole for penetrating an anchor bolt formed in a side wall of a concrete forming form, and a hole for the anchor bolt. At a predetermined distance from the side wall surface outside the side wall where the through hole is formed, and installed in parallel with the side wall surface, the anchor bolt is penetrated at a predetermined location in combination with the through hole of the anchor bolt. It is characterized by including a plate body provided with a hole for holding horizontally, and a clip for sandwiching and fixing an anchor bolt penetrating the hole of the plate body on both sides of the plate body.

[0011]

According to the anchor bolt holding device for forming concrete having the above structure, the anchor bolt is penetrated and installed in two holes, the through hole in the side wall of the formwork and the hole of the plate body installed outside the side wall. However, the penetrating portion of the plate body is further sandwiched by one clip.
That is, the outside and the inside are simultaneously sandwiched by the predetermined length clips centering on the plate body of the anchor bolt penetrating the hole of the plate body. This effectively prevents the anchor bolt from being displaced in the direction in which the side wall penetrates into the anchor bolt through hole and the plate body through hole.
This is because the anchor bolt is sandwiched between the clips before and after the plate body, so that the movement of the clip is regulated by the plate body. It is because it is done.

The hole formed in the side wall or the plate body through which the anchor bolt is inserted has a relatively large play relative to the outer diameter of the anchor bolt in order to easily remove the side wall or the plate body after the concrete body is formed. It is formed as an inside diameter. Therefore, in a state where the anchor bolt is penetrated through the hole, the anchor bolt is inclined within the range of its play, but the clip is used to clamp the anchor bolt between the side wall side and the outer side of the plate body. It is also possible to prevent inclination.

As described above, according to the present invention, it is possible to stably hold the anchor bolt at an appropriate position and at an appropriate angle during the time when concrete is poured into the formwork and until the concrete is solidified. The body can be formed accurately.

Further, the anchor bolt projecting outward from the plate body is clipped by the clip having a predetermined length.
By adjusting the length of the projecting outward from the plate body based on the clipping length of the clip, the length of the portion of the anchor bolt projecting outward from the concrete body can be set more easily and accurately. It becomes possible.

[0015]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a partial sectional view of a mold showing the entire structure of the embodiment.

In the figure, a mold 10 is formed by a channel member having a U-shaped vertical cross section. An anchor bolt 1 is provided on the side wall 10a of the formwork 10.
2 is formed.
In this embodiment, the gap filling member 16 is attached so that the anchor bolt of the through hole 14 can be inserted as firmly as possible. The gap filling member 16 is formed in a ring shape as shown in FIGS. 2 (A) and 2 (B), and a small projection is formed on the inner diameter thereof, and the inserted anchor bolt 12 is pressed as much as possible. It is configured to be able to hold. Since the filling member 16 is formed of a synthetic resin such as plastic, there is no possibility that the removal of the mold 10 after the formation of the concrete body is hindered.

A plate body 18 is attached to the outer end 10b of the formwork 10. The plate body 18 is mounted substantially perpendicular to the production bed 20 so as to be substantially parallel to the side wall 10a of the mold. The plate body 18 also has a hole 22 through which the anchor bolt 12 is inserted. The position of the hole 22 is such that the anchor bolt 12 passed through the through hole 14 of the mold 10 can be inserted into the production bed 20 in a substantially horizontal state.

With respect to the anchor bolts 12 inserted into the holes 22, both sides of the plate body 18, that is, both the outwardly projecting portions and the portion on the side of the mold 10 are clipped by the clips 24.
It is sandwiched between. The clip 24 is configured such that the anchor bolt 12 can be sandwiched between both sides of the plate body 18 by one piece.

FIG. 3 is a view showing a specific structure of the clip 24. FIG. 3A is a perspective view of the clip 24 with the anchor bolt 12 sandwiched between the clips 24, and FIG. () Shows a plan view of the clip 24, respectively.
As shown in the drawing, the clip 24 is always urged in the direction of holding the anchor bolt 12 on the side of the holding portion 24a which is a portion for holding the anchor bolt. It is configured so that it can be opened by operation. That is, the operation unit 2
When a force is applied in a direction to reduce the distance between the hands 4b by hand, the holding portion 24a is opened and the anchor bolt can be held.

As shown in FIG. 2B, a cut portion 26 is formed at a predetermined position of the clip 24. By disposing the clip 24 so that the plate body 18 is located at the cut portion 26, the anchor bolts 12 penetrating the plate body can be simultaneously sandwiched on both sides of the plate body 18. That is, as shown in the figure, the holding portions 24a of the anchor bolts are formed on both sides of the cuts 26. The width of the cut 26 is substantially equivalent to the thickness of the plate body 18, and is preferably as wide as possible to abut on both surfaces of the plate body 18.

Next, an operation of manufacturing a concrete body with anchor bolts by the anchor bolt holding device having the above-described configuration will be described.

First, as shown in FIG. 4, a filling member 16 is installed in a through hole 14 formed in a side wall 10a of a mold 10, and an anchor bolt 12 is inserted into the filling member 16 by an arrow 2 as shown in FIG.
Insert in the 00 direction. Then, the tip of the anchor bolt 12 is inserted through the hole 22 of the plate body 18. Next, an operation of sandwiching the anchor bolt 12 on both sides of the plate body 18 by a clip (not shown) is performed.
At this time, the plate 1 of the holding portion 24a of the clip 24
By setting the amount of protrusion of the anchor bolt 12 based on the width of the portion outside the portion 8, the horizontal positioning of the anchor bolt 12 can be performed accurately. For example,
The width of the clip 24 holding portion 24a and the anchor bolt 1
By making the amounts of protrusion of the second plate body 18 approximately equal, accurate positioning can be performed by the positioning operation of the tip of the anchor bolt 12 and the armrest of the plate body 18.

As a result, the anchor bolts 12 are not only positioned in the horizontal direction, but also the inclination and the lateral movement of the clip 24 are regulated by the plate member 18, so that the anchor bolts 12 are also inclined or misaligned. And is stably maintained. Therefore, the concrete is poured into the formwork in this state, but also at this time, the displacement of the anchor bolt 12 is effectively prevented. The poured concrete is solidified, and the member 100 is completed with proper anchor bolts buried therein. In the above embodiment, by coloring the clip 24 in a color that is conspicuous at the work site, the installation position of the anchor bolt 12 and the operation of collecting the clip 24 can be extremely easily performed.

The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the invention.

For example, although the filler 16 is attached to the through hole 14 of the outer frame, the filler 16 is not always necessary, and the anchor bolt 12 can be passed through as it is.

The cross-sectional shape of the formwork 10 is not limited to the above-mentioned structure using the intoxicating channel member, but may be any other structure as long as the concrete has sufficient strength to store the poured concrete. It is possible. Therefore,
The installation of the plate body 18 is not limited to that of the above-described embodiment, and various arrangements can be used as long as they can be installed at predetermined intervals outside the formwork.

Further, although the clip 24 is formed separately from the mold 10, it is not limited to this, and can be integrated by welding or the like.
