Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor bolt holder for preventing an anchor bolt inserted into a rising portion of a reinforced concrete foundation from being tilted by an impact at the time of placing concrete.

[0002]

2. Description of the Related Art An anchor bolt A is subjected to a series of operations as described below to determine a plane position and a height with respect to a rising portion 151b of a reinforced concrete foundation, for example, a solid foundation 151, and FIG. The state is as shown.
First, the upper portion of the anchor bolt A is inserted into the anchor bolt insertion hole provided in the anchor plate 153 provided between the upper ends of the formwork 152 erected on the base portion 151a of the solid foundation 151. . Subsequently, the nut member 154 is screwed onto an upper portion of the anchor bolt A inserted into the anchor bolt insertion hole and projected above the anchor plate 153. Then, the anchor bolt A is suspended by the anchor plate 153 via the nut member 154 and does not come off from the anchor bolt insertion hole.
Is determined. In addition, the nut member 154
However, when it is rotated in a state of being screwed on the upper part of the anchor bolt A, the anchor bolt A moves vertically. Therefore,
The height of the anchor bolt A is determined by performing the adjustment work for setting the top end and the like of the anchor bolt A to a desired height by such vertical movement of the anchor bolt A. And
As shown in FIG. 7 (a), the concrete 1 is placed on the rising portion 151b of the reinforced concrete foundation.
55 are cast.

[0003] Here, if there is no anchor bolt holding tool, simply the anchor plate 153 and the nut member 154 are required.
When the plane position and the height of the anchor bolt A are determined in the above, the anchor bolt A is inclined due to the impact at the time of placing the concrete 155, resulting in a state as shown in FIG. 7B. . That is, the significance of the anchor bolt holder is that when the plane position and the height of the anchor bolt A are determined by the anchor plate 153 and the nut member 154, the horizontal movement of the intermediate portion of the anchor bolt A with respect to the horizontal reinforcing bar S is performed. By restraining, it is possible to prevent a situation in which the anchor bolt A is tilted by an impact at the time of placing the concrete 155.

[0004] The first conventional anchor bolt holder 102 is formed by spot welding a member 121 for holding a horizontal reinforcing bar and a member 122 for inserting an anchor bolt, as shown in FIG. Some of the members 121 for gripping the horizontal reinforcing bar are provided with a projection 121a that abuts on the side of the node T1 of the horizontal reinforcing bar S to restrict the horizontal movement of the intermediate portion of the anchor bolt A. The conventional second anchor bolt holder 101 is formed by bending a single wire as shown in FIG. 8A, and allows a portion 111 for holding a horizontal reinforcing bar to pass through the anchor bolt. And part 112. That is, according to these anchor bolt holders, the horizontal movement of the intermediate portion of the anchor bolt A can be restrained with respect to the horizontal reinforcing bar S, so that the inclination movement of the anchor bolt A at the time of placing concrete 155 can be prevented. It is possible (see FIG. 7).

[0005]

However, in the first anchor bolt holder 102, a member 121 for gripping the horizontal reinforcing bar and a member 122 for inserting the anchor bolt are provided.
In addition to the fact that it takes about two times as much as that of a single member, it is indispensable to perform spot welding, which takes time to join these members. Therefore, an increase in manufacturing cost cannot be avoided. In the first anchor bolt holding tool 102,
It is practically almost impossible to correspond to the distance between the horizontal reinforcing bars S and the anchor bolts A, which differ for each individual design. That is, in a specific design, while the horizontal reinforcing bar is uniformly located at the center of the rising portion in the width direction, the anchor bolt is located at a position off the center of the rising portion in the width direction. There are many cases. therefore,
The spacing between horizontal rebars and anchor bolts will vary for each individual design. However, the first anchor bolt holder 10
2, a member 121 for gripping the horizontal reinforcing bar and a member 122 for inserting the anchor bolt corresponding to the spacing between the horizontal reinforcing bar S and the anchor bolt A, which are separated for each individual design.
It is practically almost impossible to change the distance between the holes, except for a slight change in the distance that can be dealt with by spot welding. Here, taking a configuration different from that of the first anchor bolt holder 102 in which another member is interposed between the member 121 for holding the horizontal reinforcing bar and the member 122 for inserting the anchor bolt, the production cost is further increased. Due to the increase, it is hardly conceivable. In the first anchor bolt holder 102, as shown in FIG. 8 (b), since the protrusion 121a of the member 121 for holding the horizontal reinforcing bar has a gentle mountain shape, the anchor bolt A If a large impact is received at the time of installation, the protrusion 121a may climb over the node T1 of the horizontal reinforcing bar S, and there is a problem that the function of restricting the horizontal movement of the intermediate portion of the anchor bolt A is not sufficiently performed. .

On the other hand, a second anchor bolt holder 101
Then, as shown in FIG.
And the horizontal reinforcing bars S are constrained by a configuration such that the horizontal reinforcing bars S are in contact with each other, so that it is impossible to appropriately manufacture the horizontal reinforcing bars S and the anchor bolts A in accordance with the intervals of the individual design. That is, the second anchor bolt holder 101
In this case, unlike the first anchor bolt holder 102, a slight change in the interval is not possible due to the configuration. In addition, in the second anchor bolt holding tool 101, as shown in the figure, the anchor bolt A is strongly pressed against the horizontal reinforcing bar S to restrain both, so that the horizontal movement of the intermediate portion of the anchor bolt A is restrained. Not only that, the vertical movement of the anchor bolt A is also unnecessarily restrained, and there is a problem that the work of adjusting the height of the anchor bolt A becomes considerably difficult.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an anchor bolt retainer which can significantly reduce the production cost and can appropriately cope with the spacing between the horizontal reinforcing bar and the anchor bolt which varies depending on individual designs. is there.

[0008]

That is, an anchor bolt holding device according to the present invention comprises a horizontal reinforcing bar gripping portion for gripping a horizontal reinforcing bar, an anchor bolt inserting portion for inserting an anchor bolt, and the horizontal reinforcing bar gripping portion. A connecting portion for connecting the horizontal reinforcing bar grip portion and the anchor bolt insertion portion so that the anchor bolt becomes vertical when the horizontal reinforcing bar is gripped, and one thin plate is bent.

The anchor bolt holder according to the present invention is made of one thin plate, unlike the one made of two members, so that the first anchor bolt holder 1 described above is used.
Compared to the case of No. 02, not only the actual manufacturing labor is reduced to approximately half, but also expensive spot welding is not required, so that the manufacturing cost can be greatly reduced.

[0010] In addition, the anchor bolt holder according to the present invention is formed by bending one thin plate to form a horizontal reinforcing bar gripping portion, an anchor bolt insertion portion, and a connecting portion. (And sometimes the width)
Since the distance between the horizontal reinforcing bar gripping portion and the anchor bolt insertion portion can be changed as appropriate, it is possible to manufacture the horizontal reinforcing bar and the anchor bolt appropriately corresponding to the different intervals between the horizontal reinforcing bars and the anchor bolts for each individual design.

[0011] In such technical means, the "connecting portion" is formed by bending one thin plate, and the horizontal reinforcing bar is set so that the anchor bolt is vertical when the horizontal reinforcing bar gripper grips the horizontal reinforcing bar. Any material may be used as long as the gripping portion and the anchor bolt insertion portion can be connected. However, from the viewpoint of realizing free correspondence to the spacing between the horizontal reinforcing bars and anchor bolts that differ for each individual design in the construction on site, the `` connection part ''
It is preferable that the bending for adjusting the interval between the horizontal reinforcing bar grip portion and the anchor bolt insertion portion is free. As such a connecting portion, for example, there is a connecting portion having an elongated shape that allows free bending in construction on site.

The "horizontal reinforcing bar gripping portion" is formed by bending one thin plate, and is capable of gripping a horizontal reinforcing bar so as to restrict the horizontal movement of the intermediate portion of the anchor bolt. Regardless of the form of restraining the horizontal movement of the intermediate portion of the anchor bolt or the shape of the anchor bolt being bent. However, from the viewpoint of properly restraining the horizontal movement of the intermediate part of the anchor bolt,
It is preferable that the “horizontal reinforcing bar gripping portion” includes a claw portion attached between nodes of the horizontal reinforcing bar. Furthermore, the `` anchor bolt insertion part '' is formed by bending a thin plate, and if it is possible to insert the anchor bolt vertically, it is necessary to determine what shape it is bent into. It doesn't matter. In addition, inserting an anchor bolt through the “anchor bolt insertion portion” includes inserting the anchor bolt through the anchor bolt insertion portion while gripping the anchor bolt with the anchor bolt insertion portion.
However, from the viewpoint of avoiding a situation in which the elastic return force is not lost and the holding by the insertion of the anchor bolt becomes impossible, the “anchor bolt insertion portion”
Is preferably bent in a rectangular shape in the transverse direction of the anchor bolt.

Is a side view showing a schematic configuration of the anchor bolt holder, FIG. 4 is a plan view illustrating the operation of the anchor bolt holder, and FIG. 5 is a cross-section illustrating a method of constructing a solid foundation using the anchor bolt holder. FIG.

In the first embodiment, as shown in FIG. 1, the anchor bolt holder 1 is
, An anchor bolt insertion portion 12, and a connecting portion 13, and are configured by bending one thin plate 1a as shown in a developed view in FIG.

That is, this anchor bolt holder 1
Is made of one thin plate 1a as shown in the figure, and is not made up of two members like the first anchor bolt holder 102 described above, and the substantial manufacturing time is approximately In addition to halving, expensive spot welding is not required, so that the manufacturing cost can be significantly reduced. Also, this anchor bolt holder 1 is
One thin plate 1a having an appropriate shape as shown in the figure is bent, and a horizontal reinforcing bar gripper 11 and an anchor bolt insertion portion 12 are bent.
And the connecting portion 13. By changing the length L of the connecting portion 13 in one thin plate 1 a, the interval between the horizontal reinforcing bar gripping portion 11 and the anchor bolt insertion portion 12 can be appropriately changed. It is possible to manufacture the horizontal reinforcing bar S and the anchor bolt A in accordance with the intervals between the reinforcing bars, which are different from one another.

The material of the anchor bolt holder 1 according to the first embodiment is made of stainless steel. However, the present invention is not limited to this.
For example, a material made of a non-ferrous metal, a resin, or the like may be appropriately selected according to the characteristics of the connector 13 and the connecting portion 13. Hereinafter, each component will be described in detail.

(1) Horizontal Reinforcing Bar Holder 11 The horizontal reinforcing bar holding unit 11 is, as shown in FIG.
a is formed by bending a part of the horizontal reinforcing bar S
It plays a role of gripping. Here, the gripping of the horizontal reinforcing bar gripping portion 11 with respect to the horizontal reinforcing bar S is described in FIGS.
As shown in (1), this is achieved by utilizing the elastic restoring force of the horizontal reinforcing bar gripping portion 11 which is shaped to be wound between the nodes T1 of the horizontal reinforcing bar S. That is, when the horizontal rebar S is gripped by the horizontal rebar gripper 11, the horizontal rebar gripper 11
When the horizontal reinforcing bar S is inserted into the horizontal reinforcing bar gripping portion 11 and then the hand that widens the entrance is released, the horizontal reinforcing bar gripping portion 11 returns to the original shape by the elastic restoring force. So that the horizontal rebar gripper 11
The horizontal rebar S can be gripped by utilizing the elastic restoring force. In the first embodiment, the horizontal reinforcing bar grip 11
Is wound around the node T1 of the horizontal reinforcing bar S from the upper side, and the entrance is formed on the side of the anchor bolt A. However, the present invention is not limited to this, and the horizontal reinforcing bar gripping portion 11 of the horizontal reinforcing bar S The entrance may be formed between the nodes T1 so that the entrance is formed on the opposite side to the anchor bolt A. In addition, also in the horizontal reinforcing bar gripping portion 11, if technical means such as a guide portion 12a of the anchor bolt insertion portion 12 described later is formed, the horizontal reinforcing bar gripping portion 1 can be formed.
The work of inserting the horizontal reinforcing bar S from the entrance 1 can be facilitated. As shown in FIG. 5, the horizontal reinforcing bar S is an upper horizontal reinforcing bar that is provided as a main bar at the rising portion 51 b of the solid foundation 51 as a main bar.
It is. The reason that the anchor bolts A are gripped only by the upper horizontal reinforcing bars S is that the anchor bolts A are fixed to any one of the horizontal reinforcing bars S in order to restrain the horizontal movement of the intermediate portion of the anchor bolts A when the concrete 55 is poured. This is because it is sufficient to hold the anchor bolts A. In this case, it is easier to hold the anchor bolts A to the upper horizontal reinforcing bars S than to hold the lower horizontal reinforcing bars S.

As shown in FIG. 1, the horizontal reinforcing bar gripping portion 11 in the first embodiment has a claw portion 11a mounted between the nodes T1 of the horizontal reinforcing bar S. Therefore, according to such a horizontal reinforcing bar gripping portion 11, even if the anchor bolt A receives a large impact at the time of placing the concrete 155, as shown in FIG.
Is always in contact with the node T1 of the horizontal reinforcing bar S, so that the horizontal movement of the intermediate portion of the anchor bolt A can be accurately restrained.

The attachment of the claw portion 11a to the horizontal reinforcing bar S is performed by forming the claw portion 11a so as to wind around the node T1 of the horizontal reinforcing bar S as shown in FIG. I have. Therefore, according to such a horizontal reinforcing bar gripping portion 11, even if the claw portion 11a is to be wound around the rib T2 of the horizontal reinforcing bar S as shown in FIG. Since the side portion of the portion always comes into contact with the node T1 of the horizontal reinforcing bar S, the horizontal movement of the intermediate portion of the anchor bolt A can be accurately restrained.

Therefore, such a horizontal rebar gripping portion 1
According to the first embodiment, the first anchor bolt holder 10 described above is used.
2. When anchor bolt A is subjected to a large impact when concrete 155 is poured, as in the case of 2, it may not be possible to sufficiently perform the function of restraining the horizontal movement of the intermediate portion of anchor bolt A. There is no.

(2) Anchor bolt insertion portion 12 As shown in FIG. 1, the anchor bolt insertion portion 12 is formed by bending a part of one thin plate 1a.
As shown in (a), it serves to hold the anchor bolt A in a state of being inserted.

As shown in FIG. 1, the anchor bolt insertion portion 12 in the first embodiment is bent in a rectangular shape in the transverse direction of the anchor bolt A. According to such an anchor bolt insertion portion 12, since a part of one thin plate 1a is bent into a square shape, the entrance of the anchor bolt insertion portion 12 is expanded while the anchor bolt A is inserted. Since the shape of the entrance always returns to the original shape after the insertion, the function of restraining the horizontal movement of the intermediate portion of the anchor bolt A with respect to the horizontal reinforcing bar S can be secured.

That is, as shown in FIG. 4 (b), if the anchor bolt insertion portion into which the anchor bolt A is inserted is the anchor bolt insertion portion 22 that is bent in a circular shape in the transverse direction of the anchor bolt A. When the anchor bolt A is inserted after the entrance of the anchor bolt insertion portion 22 is expanded, the entrance of the anchor bolt insertion portion 22 remains expanded, and the anchor bolt A cannot be held in the inserted state. Therefore, the function of restraining the horizontal movement of the intermediate portion cannot be performed. However, according to such an anchor bolt insertion portion 12, after inserting the anchor bolt A,
Since the entrance of the anchor bolt insertion portion 12 always returns to the original shape by the elastic restoring force, it is possible to avoid a situation where the anchor bolt A cannot be held in the inserted state as shown in FIG. . In addition, since such an anchor bolt insertion portion 12 holds the anchor bolt A in the inserted state, the anchor bolt A
Is not restrained more than necessary, thereby making it possible not to hinder the work of adjusting the height of the anchor bolt A. Therefore, according to such an anchor bolt insertion portion 12, the two anchor bolts A are restrained by strongly pressing the anchor bolts A against the horizontal reinforcing bars S, which is a problem with the second anchor bolt holder 101 described above. As a result, a situation that makes the operation of adjusting the height of the anchor bolt A difficult is not caused. Further, as shown in FIG. 1, the anchor bolt insertion portion 12 is formed by bending a part of one thin plate 1a inward so as to form a square corresponding to the outer shape of the anchor bolt A. Is bent outward to form a guide portion 12a. According to such a guide portion 12a, it is possible to facilitate the operation of inserting the anchor bolt A from the entrance of the anchor bolt insertion portion 12. In addition,
As shown in FIG. 5, the anchor bolt A has a length dimension and a shape for obtaining a sufficient pull-out resistance. In particular, a hook is formed at the lower end of the anchor bolt A. This makes it possible to secure a sufficient pull-out resistance. As shown in the figure, a male screw to which the nut member 54 for fastening the base 56 is to be screwed is formed on the upper part of the anchor bolt A. Further, as shown in the figure, the anchor bolt A is formed by bending at an intermediate portion such that an upper axis is eccentric relative to a lower axis. Thereby, the anchor bolt A
In the configuration in which the middle part of the anchor is held by the side of the horizontal reinforcing bar S, the upper part of the anchor bolt A protruding above the horizontal reinforcing bar S can be positioned at the center in the width direction of the rising portion 51b.

(3) Connecting Portion 13 As shown in FIG. 1, the connecting portion 13 is formed by bending a part of one thin plate 1a.
Serves to connect the horizontal reinforcing bar gripping portion 11 and the anchor bolt insertion portion 12 such that the anchor bolt A is vertical when the horizontal reinforcing bar S is gripped. According to such a connecting portion 13, one thin plate 1a as shown in FIG.
By changing the length L in the horizontal rebar gripper 1
1 and the distance between the anchor bolt insertion portions 12 can be appropriately changed. Therefore, it is possible to manufacture the horizontal reinforcing bar S and the anchor bolt A in accordance with the interval between the horizontal reinforcing bars S, which are different for each individual design.

Next, referring to FIG. 5, a solid foundation 51 using the anchor bolt holder 1 according to the first embodiment will be described.
The construction method will be described.

(1) Restriction of Horizontal Movement of Intermediate Portion of Anchor Bolt At the time of construction of the solid foundation 51, the construction of the base portion 51a has already been completed, and the rebar of the rising portion 51b has been assembled. (FIG. 5A). In such a state, an operation of holding the anchor bolt A to the horizontal reinforcing bar S by the anchor bolt holder 1 is performed. Specifically, first, the anchor bolt A is inserted into the anchor bolt insertion portion 12. Next, the horizontal rebar S is gripped by the horizontal rebar gripper 11 that is continuous from the anchor bolt insertion portion 12 through which the anchor bolt A is inserted so as to correspond to the designed planar position of the anchor bolt A. This allows
The anchor bolt A becomes vertical so that the distance between the horizontal reinforcing bar S and the anchor bolt A is maintained as designed, and the horizontal movement of the intermediate portion of the anchor bolt A is restricted (FIG. 5B). ). Conversely, after the horizontal rebar S is gripped by the horizontal rebar gripper 11, the anchor bolt A may be inserted through the anchor bolt insertion portion 12.

(2) Assembling the Formwork of the Standing Up Section Subsequently, the work of setting up the formwork 52 of the rising section 51b on the base section 51a of the solid foundation 51 which has already been completed is performed (FIG. 5). (C)).

(3) Determining the Planar Position of the Anchor Bolt Next, the anchor plate 53 is erected between the upper ends of the mold frames 52 corresponding to the designed planar positions of the anchor bolts A. Specifically, the anchor plate 53 is erected between the upper ends of the mold frames 52 in a state where the upper portion of the anchor bolt A whose intermediate portion is restrained by the anchor bolt holder 1 is inserted into the anchor bolt insertion hole provided in the anchor plate 53. (FIG. 5C). Subsequently, the nut member 54 is screwed to the upper portion of the anchor bolt A which is projected above the anchor plate 53 as a result of being inserted into the anchor bolt insertion hole. Then, since the anchor bolt A does not come off from the anchor bolt insertion hole, first, the plane position of the anchor bolt A is determined (FIG. 5D).

(4) Determination of Height of Anchor Bolt Next, by rotating the nut member 54 screwed on the upper part of the anchor bolt A, the anchor bolt A is vertically moved (adjusted in height) ( FIG. 5D). At this time, since the anchor bolt insertion portion 12 is configured to hold the anchor bolt A in a state of being inserted, it is possible to smoothly adjust the height of the anchor bolt A.

The height of the anchor bolt A is determined by setting the top end of the anchor bolt A to a desired height.

(5) Casting of concrete at rising portion Next, concrete 55 is cast on the base portion 51a of the solid foundation 51 and inside the formwork 52 of the rising portion 51b (FIG. 5 (e)). ). At this time, concrete 55
However, the anchor bolt A receives an impact with the installation of the anchor bolt A. However, since the anchor bolt holding tool 1 functions to restrain the horizontal movement of the intermediate portion of the anchor bolt A with respect to the horizontal reinforcing bar S, the anchor bolt A It does not cause the bolt A to cause the tilt movement.

(6) Tightening of the foundation After the curing period of the concrete 55 has passed, the solid foundation 5
The mold 52 of the first rising portion 51b is dismantled. Then, an operation of fixing the base 56 to the upper part of the anchor bolt A is performed. Specifically, the base 56 is set so that the upper part of the anchor bolt A protruding from the upper surface of the rising part 51b of the solid foundation 51 whose construction is completed is inserted into the anchor bolt insertion hole provided in the base 56.
Put on top of. Subsequently, the nut member 54 is screwed onto the upper part of the anchor bolt A exposed in the anchor bolt insertion hole of the base 56 (FIG. 5F).

As described above, according to the anchor bolt holder 1 according to the first embodiment, one thin plate 1a is bent to form the horizontal reinforcing bar grip 11, the anchor bolt insertion portion 12, and the connecting portion 13. Therefore, only by changing the length L of the connecting portion 13 in one thin plate 1a, the interval between the horizontal reinforcing bar gripping portion 11 and the anchor bolt insertion portion 12 can be appropriately changed, and therefore, it is different for each individual design. It has become possible to manufacture the reinforcing member appropriately corresponding to the interval between the horizontal reinforcing bar S and the anchor bolt A. In addition, since it is made of one thin plate 1a, it has become possible to significantly reduce the manufacturing cost through a significant reduction in the labor of substantial manufacturing and avoidance of expensive spot welding.

Embodiment 2 FIG. 6 is a view showing a schematic configuration of an anchor bolt holder 2 according to Embodiment 2 of the present invention (FIG. 6 (a) is a front view and a side view before mounting, and FIG. (b) is a side view after mounting). Note that components similar to those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and detailed description thereof is omitted here.

The basic structure of the anchor bolt holder 2 according to the second embodiment is made of a thin plate having the same material and thickness as the anchor bolt holder 1 and has a horizontal reinforcing bar grip 11.
In addition, the anchor bolt insertion portion 12 has substantially the same shape and structure as the first embodiment. However, unlike the first embodiment, the connecting portion 13 is
And it has such a property that it can be bent freely to adjust the interval between the anchor bolt insertion portions 12. That is, in the anchor bolt holder 2, as shown in FIG. 6A, unlike the anchor bolt holder 1, the connecting portion 13 is manufactured to have a considerably elongated shape. Therefore, as shown in FIG. 6B, the connecting portion 13 is provided between the horizontal reinforcing bar gripping portion 11 and the anchor bolt insertion portion 12 in accordance with the interval between the horizontal reinforcing bar S and the anchor bolt A in the construction on site. Free bending is possible such that the interval is set short (FIG. 6B left) or long (FIG. 6B right).

Therefore, according to the anchor bolt holder 2 according to the second embodiment, unlike the first embodiment,
It has become possible to freely cope with the spacing between the horizontal reinforcing bars S and the anchor bolts A, which vary for each individual design, in the construction on site.
