[0004] The anchor fixing member connecting method described in Patent Document 1 requires pin holes for the fixing pins on the top surface of the formwork. Therefore, if there are no pin holes on the top surface of the formwork, the connecting method described in Patent Document 1 cannot be used. Furthermore, even if there are pin holes on the top surface of the formwork, the pin holes in the anchor fixing member and the pin holes in the formwork may not be aligned. In such cases, the connecting method described in Patent Document 1 cannot be used.

[0005] The present invention aims to provide a connector that can easily connect multiple anchor fixing members without using pin holes on the top surface of a formwork, and also to provide a method for connecting multiple anchor fixing members using the connector. [Means for solving the problem]

(Item 1) A connector for connecting a plurality of anchor fixing members having through holes and arranged on the top surface of a formwork, a base portion disposed below the plurality of anchor fixing members and not insertable into the through hole; an insertion portion extending upward from the base portion and insertable into the through holes of the plurality of anchoring members; A connector comprising:

[0007] (Item 2) The tip of the insertion part is tapered. Item 1. The connector according to item 1.

[0008] (Item 3) A method for connecting multiple anchor fixing members using a connector as described in item 1 or 2.

[0009] (Item 4) Stacking the plurality of anchor fixing members so that the through holes are aligned; The plurality of anchor fixing members are connected together by inserting the insertion portion into the through-hole. The linking method according to item 3.

[0010] (Item 5) The anchor fixing members are arranged so as to abut against each other, The plurality of anchor fixing members are connected together by inserting the insertion portion into the through-hole. The linking method according to item 3. [Effects of the Invention]

[0011] The connector of the present invention can connect multiple anchor fixing members by inserting the insertion portion extending upward from the base portion into the through-holes of the multiple anchor fixing members. Because the connector of the present invention does not use pin holes in the top surface of the formwork to connect the multiple anchor fixing members, by using the connector of the present invention, multiple anchor fixing members can be connected even if pin holes are not provided in the top surface of the formwork.

[0013] The connector 10 of the present invention will be described with reference to the drawings. For convenience of explanation, the top and bottom of FIG. 1 will be referred to as the top and bottom of the connector 10.

[0014] The connector 10 of the present invention is used to connect multiple anchor fixing members P1, P2 (see FIGS. 2 and 3) for positioning anchor bolts for a house foundation. In one embodiment, the multiple anchor fixing members P1, P2 are connected by stacking them so that their through holes h are aligned, and inserting a portion of the connector 10 into the through hole h. Note that although FIGS. 2 and 3 show the case where two anchor fixing members P1, P2 are connected, the number of anchor fixing members to be connected may be three or more.

[0015] <1. Structure of the connector> 1, connector 10 includes a base portion 11 and an insertion portion 12. Connector 10 is made of, for example, metal or resin, and is preferably a one-piece molded product.

[0016] The base 11 has a first surface (lower surface) that faces the top surface of the formwork F and a second surface (upper surface) opposite the first surface. The diameter of the base 11 is larger than the diameter of the through holes h of the anchor fixing members P1 and P2. Therefore, the base 11 cannot be inserted into the through holes h. As shown in FIG. 3, when the connector 10 is in use, the base 11 is placed on the top surface of the formwork F and below the anchor fixing members P1 and P2 so that the first surface contacts the top surface of the formwork F. In the embodiment shown in FIG. 2, the base 11 is disk-shaped. However, the shape of the base 11 is not limited to a disk shape and may be a shape other than a disk shape, such as a rectangular shape.

[0017] The insertion portion 12 extends upward from the second surface of the base portion 11. The diameter of the insertion portion 12 is smaller than the diameter of the through-holes h of the anchor fixing members P1 and P2, and the insertion portion 12 is inserted into the through-holes h during use. The insertion portion 12 has a length that allows at least the tip of the insertion portion 12 to be inserted into the through-hole h of the uppermost anchor fixing member (anchor fixing member P2 in Figures 2 and 3). The insertion portion 12 preferably has a length that allows the tip of the insertion portion 12 to protrude from the through-hole h of the uppermost anchor fixing member. In other words, the length of the insertion portion 12 is preferably greater than the total thickness of all anchor fixing members P1 and P2. In the embodiment shown in Figure 2, the insertion portion 12 is cylindrical. However, the shape of the insertion portion 12 is not limited to a cylindrical shape and can be determined appropriately according to the shape of the through-hole h.

[0018] <2. How to connect anchor fixing components> 2 and 3, a method for connecting multiple anchor fixing members P1, P2 using a connecting device 10 will be described. Note that Figures 2 and 3 show a state in which anchor fixing members P1, P2 are connected at two locations using two connecting devices 10. However, the number of connecting devices 10 used and the number of connecting locations are not limited to this, and multiple anchor fixing members P1, P2 may be connected at one location using one connecting device 10, or may be connected at three or more locations using three or more connecting devices 10.

[0019] 2 and 3, the insertion portion 12 of the connector 10 is inserted into the through-hole h from below the anchor fixing members P1, P2. The base portion 11 is positioned on the top surface of the formwork F and below the anchor fixing members P1, P2, and is not inserted into the through-hole h.

[0020] For example, the procedure for connecting multiple anchor fixing members P1, P2 is as follows: first, multiple anchor fixing members P1, P2 are stacked on top of each other on the top surface of the formwork F so that the through holes h of the multiple anchor fixing members P1, P2 are aligned. Then, the connection points of the multiple anchor fixing members P1, P2 are lifted, and the insertion portion 12 of the connector 10 is inserted into the through holes h of the multiple anchor fixing members P1, P2 from below. Because the diameter of the base 11 is larger than the diameter of the through holes h, the base 11 does not insert into the through holes h but comes into contact with the underside of the lower anchor fixing member P1. Then, the user holds the base 11 with their hand, for example, while keeping the insertion portion 12 inserted into the through holes h, and lowers the multiple anchor fixing members P1, P2 together with the connector 10 onto the top surface of the formwork F. In this way, the multiple anchor fixing members P1, P2 can be connected.

[0021] In addition, in order to fix the anchor fixing members P1, P2 to the formwork F, the anchor fixing members P1, P2 and the formwork F may be fixed together by a fixing tool such as a vice, if necessary.

[0022] <3. Features> The connector 10 of the present invention can connect multiple anchor fixing members P1, P2 without using pin holes in the top surface of the formwork F. Therefore, even if there are no pin holes in the top surface of the formwork F or if the pin holes in the top surface of the formwork are misaligned with the through holes h of the anchor fixing members P1, P2, the multiple anchor fixing members P1, P2 can be connected.

[0023] Since the base 11 is not inserted into the through-hole h, it becomes easier for the user to hold the connector 10 from the time the insertion portion 12 is inserted into the through-hole h until the time the connector 10 is lowered onto the top surface of the formwork F.

[0024] <4. Modifications> The fastener 10 and connecting method of the present invention can be modified in various ways without departing from the spirit of the present invention. Modifications of the fastener 10 and connecting method of the present invention will be described below. The modifications shown below can be combined as appropriate without departing from the spirit of the present invention.

[0025] (1) As shown in Fig. 4, the tip of the insertion section 12 may be tapered so that the diameter decreases toward the top. The tapered tip of the insertion section 12 makes it easier to insert the insertion section 12 into the through-hole h of the anchor fixing members P1 and P2.

[0026] (2) The base 11 may be provided with a plurality of insertion portions 12. For example, as shown in Fig. 5, the connector 10 may be configured such that the base 11 extends in the foundation width direction from one formwork F to the other formwork F so that the connector 10 can be erected on a pair of formworks F, and the two insertion portions 12 extend upward from the base 11.

[0027] (3) Another procedure for connecting multiple anchor fixing members P1, P2 is to first lift up the connection point of the lower anchor fixing member P1 and insert the insertion portion 12 of the connector 10 into the through-hole h of the anchor fixing member P1. The user holds the base 11 with their hand, for example, to keep the insertion portion 12 inserted into the through-hole h, and then lower the anchor fixing member P1 together with the connector 10 onto the top surface of the formwork F. Then, the anchor fixing member P2 is placed on the top surface of the formwork F so that the insertion portion 12 is inserted into the through-hole h of the upper anchor fixing member P2. In this way, multiple anchor fixing members P1, P2 can be connected.

[0028] (4) Another procedure for connecting multiple anchor fixing members P1, P2 involves first placing the connector 10 on the top surface of the formwork F so that the first surface of the base 11 is in contact with the top surface of the formwork F. Because the diameter of the base 11 is larger than the diameter of the insertion portion 12, the connector 10 can be stably placed on the top surface of the formwork F. The multiple anchor fixing members P1, P2 are placed one by one on the top surface of the formwork F so that the insertion portion 12 is inserted into each of the through holes h. Alternatively, the multiple anchor fixing members P1, P2 can be stacked so that the through holes h are aligned, and then the multiple anchor fixing members P1, P2 are placed on the top surface of the formwork F so that the insertion portion 12 is inserted into each of the through holes h. In this way, the multiple anchor fixing members P1, P2 can be connected.

[0029] (5) The connector 10 may be configured to be adhesive to the formwork F. For example, if the formwork F is made of a magnetic material, such as a steel plate, that can be attached to a permanent magnet, the connector 10 may be made of a permanent magnet. Alternatively, the connector 10 may have an adhesive portion that adheres to the formwork F. The adhesive portion may be an adhesive portion, such as a double-sided tape, attached to the first surface of the base 11. If the formwork F is made of a magnetic material, such as a steel plate, that can be attached to a permanent magnet, the adhesive portion may be a permanent magnet attached to the base 11. Because the connector 10 is adhesive to the formwork F, when the connector 10 is placed on the top surface of the formwork F, it is less likely to move relative to the formwork F. Therefore, after the multiple anchor fixing members P1, P2 are connected, the multiple anchor fixing members P1, P2 are less likely to shift relative to the formwork F. Furthermore, when the connecting device 10 is placed on the top surface of the formwork F in advance as described above, and then multiple anchor fixing members P1, P2 are placed on the top surface of the formwork F so that the insertion portions 12 are inserted into each through hole h, the connecting work becomes easier.

[0030] (6) As shown in Figures 6 and 7, two anchor fixing members P1 and P2 can also be connected by butting them together rather than overlapping them. In this case, first, an installation plate Q is prepared. The installation plate Q extends from one formwork F to the other formwork F so that it can be installed on a pair of formworks F. The installation plate Q also extends from a portion of one anchor fixing member P1 to a portion of the other anchor fixing member P2. The installation plate Q has multiple through holes i. The size of each through hole i is larger than the insertion portion 12 but smaller than the base portion 11. Therefore, the insertion portion 12 can be inserted into each through hole i, but the base portion 11 cannot. The installation plate Q is placed below or above the two anchor fixing members P1 and P2 so that the through holes i of the installation plate Q are aligned with the through holes h of the two anchor fixing members P1 and P2. Then, the insertion portions 12 are inserted into the through holes i and h from below the installation plate Q and the two anchor fixing members P1, P2. In this way, the two anchor fixing members P1, P2 can be butt-joined by the connector 10. Note that instead of using the installation plate Q, as shown in FIG. 8, a connector 10 may be used that extends from one formwork F to the other formwork F so that it can be installed on a pair of formworks F, and that includes a base 11 that extends from a part of one anchor fixing member P1 to a part of the other anchor fixing member P2, and a plurality of insertion portions 12 that extend upward from the base 11 and can be inserted into the through holes h of each of the anchor fixing members P1, P2.
