Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a battledore bolt, and more particularly, to an improved battledore bolt used for joining eaves and columns, beams and columns, and body differences and through columns.

[0002]

[Prior art]

 Conventionally, as this kind of battledore bolt, there is one shown in FIG. 3, for example.

That is, in this conventional one, a rod-shaped body 5a having a threaded portion 19 at its tip is welded to one end of the plate-shaped body 1a, and the bar-shaped hole 4a is provided at the other end of the plate-shaped body 1a. Has been drilled.

When the members to be joined A and B such as beams are joined to each other in a substantially T shape by using this, the rod-shaped body 5a is inserted into the through hole 9a of the member to be joined B. Then, after temporarily fixing the nut 20 to the threaded portion 19, the bolt 15a is inserted into the through hole 13a of the member A to be joined and the bar 4a of the plate-shaped body 1a to tighten the nut 17a, and then the nut 20 Is firmly fastened to the threaded portion 19 of the rod-shaped body 5a for joining.

In this way, the frame of the building is constructed by appropriately joining the plurality of members A and B to be joined. Then, after the ridge is raised, the outer wall material 18a is installed on the outer surface side of the member B to be joined.

[0006]

[Problems to be solved by the device]

 However, the nut 20 may loosen after the ridge is raised or the outer wall member 18a is installed. In this case, it is fatal that the nut 20 cannot be fastened again by the outer wall member 18a in the conventional case. It had a problem.

[0007] Also, such inconvenience occurs even after a certain period of time has passed since the construction of the building, but in this case as well, the nut 20 cannot be re-tightened, which is one of the causes for shortening the life of the building. Was there.

Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, and an object thereof is to make it possible to maintain a good joined state of members to be joined by the battledore bolts.

[0009]

[Means for Solving the Problems]

 That is, in order to solve the above problems, the present invention provides a plate-shaped body 1 provided with a connecting portion 2 having a through hole 3 and a plate-shaped body 1 which is a separate body and has a screw portion 6 at least at one end. The rod-shaped body 5 is formed, and one end of the rod-shaped body 5 is inserted into the through hole 4 of the plate-shaped body 1 and the nut 8 is screwed into the threaded portion 6 in order to connect the both. It is a battledore bolt that is worn.

[0010]

[Action]

 Therefore, in the battledore bolt characterized by the above-mentioned structure, the other end of the rod-shaped body 5 is inserted into the through hole of one member to be joined, and the plate-shaped member 1 is fixed to the other member to be joined. To join the joining members, one end of the rod-shaped body 5 having the threaded portion 6 is inserted into the through hole 4 of the plate-shaped body 1, and the nut 8 is screwed to the threaded portion 6 to connect the two. Therefore, the nut 8 can be tightened from the inside even after the outer wall material is installed on the outer surface side of one of the members to be joined, and thus the nut 8 can be appropriately fastened as necessary. By fastening 8 together, the joined state of both members to be joined can be firmly maintained.

[0011]

【Example】

 An embodiment of a battledore bolt according to the present invention will be described below with reference to the drawings.

In FIG. 1 and FIG. 2, reference numeral 1 denotes a plate-shaped body made of a strip plate, and at one end thereof, a connecting portion 2 bent substantially vertically is formed, and the connecting portion 2 is formed. Further, a through hole 3 and a barhole 4 are formed in the plate-shaped body 1 at the other end side substantially in the center thereof.

Reference numeral 5 is a substantially columnar rod-shaped body having screw portions 6 and 7 formed at both ends, and one end of the rod-shaped body 5 is inserted into a through hole 3 provided in the connecting portion 2 of the plate-shaped body 1. It is inserted, and a nut 8 is screwed onto the thread portion 6.

The battledore bolt according to the present embodiment has the above-described configuration, and next, a case will be described in which the joined members A and B having a body difference and the like are joined using the bolt.

First, as shown in FIG. 2, both members A and B to be joined are joined by a dovetail joint in a substantially T-shape, and then a battlement plate bolt is inserted into a through hole 9 formed in the width direction of one member B to be joined. With the tip of the rod-shaped body 5 of 10 inserted, the nut 12 is temporarily fixed to the threaded portion 7 through the washer 11.

Next, a bolt 15 is inserted through a washer 14 into the through hole 13 formed in the width direction of the other member to be joined A and the bar hole 4 of the plate-like body 1, and the nut 17 is attached to the threaded portion 16. If the nut 12 is fully tightened after the tightening of the two, the members A and B to be joined are firmly and reliably joined.

In this way, after building the frame of the building, the building is raised, and further the outer wall member 18 is installed on the outer surface side of the member B to be joined as shown by the chain double-dashed line. In the meantime, the nuts 8 and 12 may loosen.

However, since the plate-shaped body 1 and the rod-shaped body 5 are connected by screwing the threaded portion 6 and the nut 8, and the connecting portion is located inside the building, the nut 8 is tightened. The wearing work can be performed without being disturbed by the outer wall member 18.

Moreover, since the nut 8 is located on the back side of the connecting portion 2 of the plate-like body 1, a space for fastening the nut 8 is secured without being interfered by the member B to be joined. It will be done and the work can be done easily.

Further, since the nut 8 can be fastened at this point, a series of subsequent construction work can be well performed, which can greatly contribute to the construction of a strong building.

Further, even after a certain period of time has passed since the construction of the building, the nut 8 can be fastened from the inside of the building such as the attic, so that the life of the building can be extended.

Besides, the rod-shaped body 5, the nut 8 and the like can be dealt with by existing ones, and since complicated work such as welding is not required, there is an advantage that the battledore bolt 10 can be easily manufactured at low cost. is there.

In the above-described embodiment, the nut 12 is screwed onto the threaded portion 7 formed at the other end of the rod-shaped body 5 to join the rod-shaped body 5 and the member B to be joined. The threaded portion may be formed on at least one end, and the joining means for joining the rod-shaped body 5 and the member B to be joined is not limited to the embodiment.

Further, the joining means for joining the plate-shaped member 1 and the member A to be joined is not limited to the above embodiment.

Further, in this embodiment, one end portion of the plate-shaped body 1 is bent to form the connecting portion 2. However, for example, the connecting portion 2 is formed by a separate member to form the plate-shaped body 1. It may be attached, and the position where the connecting portion 2 is provided does not matter.

In addition, the specific shapes of the plate-shaped body 1 and the rod-shaped body 5 can be arbitrarily changed in design within the scope intended by the present invention.

[0027]

[Effect of device]

 As described above, according to the present invention, a threaded portion is formed at one end of a rod-shaped body, and this one-sided end is inserted into a through hole formed in the connecting portion of the plate-shaped body, and a nut is screwed onto the threaded portion. Since the two are connected together, the nut can be tightened to the threaded portion of the rod even after the outer wall material has been installed and installed. The joints between them became stronger, and the special effect of contributing greatly to the construction of a good building was achieved without hindering the subsequent series of operations.

In addition, since the battledore bolt according to the present invention does not require welding work unlike the related art and has an extremely simple structure, it can be manufactured at low cost and easily. is there.
