Description
【0001】[0001]
本考案は、建築工事において例えば梁同士を接合する場合に使用する建築用打 込みピンに関するものである。 The present invention relates to a construction driving pin used for joining beams, for example, in a construction work.
【0002】[0002]
従来から木造建築においては、梁同士を接合する場合には、それぞれの梁に切 込みを形成し、これらを組合わせて接合する工法が多く行われている。 2. Description of the Related Art Conventionally, in wooden construction, when joining beams to each other, notches have been formed in each beam, and a method of joining these together and joining them has been often used.
【0003】 しかしながら、この切込みを行いこれらを組合わせる工法は、その段取りに時 間が掛かり、能率が極めて悪いという問題点がある。However, the method of making the cuts and combining the cuts has a problem that the setup takes time and the efficiency is extremely low.
【0004】[0004]
そこで、近年では補助金具を介在して梁同士を接合することが行われており、 ピン金具を補助金具に挿通することにより固定しているが、長年使用していると 緩みが生じ、地震等の場合にピン金具が抜け出す虞れが多分にある。 Therefore, in recent years, beams have been joined with an intervening auxiliary metal fitting, and the pin metal fitting is fixed by inserting it into the auxiliary metal fitting. In the case of, there is a possibility that the pin fitting may come off.
【0005】 本考案の目的は、上述の問題点を解消し、打ち込み後に木材から抜け出し難い 建築用打込みピンを提供することにある。An object of the present invention is to solve the above-mentioned problems and to provide a construction driving pin that is hard to come out of wood after driving.
【0006】[0006]
上記目的を達成するための本考案に係る建築用打込みピンは、建築用木材に固 定のために打ち込む建築用打込みピンであって、金属製の丸棒体から成り、先端 部を稍々先細とし、後端部の周囲に複数個の突起を形成したことを特徴とする。 The construction driving pin according to the present invention for achieving the above-mentioned object is a construction driving pin to be fixed to construction wood for fixing, and is made of a metal round bar, and its tip portion is slightly tapered. In addition, a plurality of protrusions are formed around the rear end portion.
【0007】[0007]
本考案を図示の実施例に基づいて詳細に説明する。 図1〜図3に示すように、本考案に係る建築用打込みピン1は、例えば長さ1 00mm、直径12mmの金属製の丸棒体を基に例えば鍛造により形成され、そ の先端部1aは稍々先細とされ、後端部1bの周囲には例えば6個の突起1cが 外側に向けて突出されている。そして、これらの突起突起1cは、打込み易くか つ抜け難くするために、先端側から後端側に向かうにつれ、外方に拡がる傾斜部 を有している。 The present invention will be described in detail with reference to the illustrated embodiment. As shown in FIGS. 1 to 3, a construction driving pin 1 according to the present invention is formed by, for example, forging based on a metal round bar body having a length of 100 mm and a diameter of 12 mm, and its tip 1a. Is slightly tapered, and for example, six projections 1c are projected outwardly around the rear end portion 1b. These projections 1c have an inclined portion that expands outwardly from the front end side toward the rear end side in order to make it easy to drive and hard to remove.
【0008】 この打込みピン1は、例えば図3に示すように第1の梁11と第2の梁12の 接合に際して使用される。第1の梁11には、予め接続金具13を例えば4組の ボルト14、ナット15により固定しておく。The driving pin 1 is used, for example, when joining the first beam 11 and the second beam 12 as shown in FIG. Connection fittings 13 are fixed to the first beam 11 in advance by, for example, four sets of bolts 14 and nuts 15.
【0009】 また、第2の梁12には接続金具13を挿入するための切込み12aを形成し ておき、この切込み12a内に接続金具13のフック部13aに係止するための ボルト16を第2の梁12に設けた孔12bに挿通し、ナット17により固定し ておく。Further, the second beam 12 is formed with a notch 12a for inserting the connecting fitting 13, and a bolt 16 for engaging with the hook portion 13a of the connecting fitting 13 is formed in the notch 12a. It is inserted through the hole 12b provided in the second beam 12 and fixed by the nut 17.
【0010】 先ず、第1の梁11に固定された接続金具13に第2の梁12を仮固定するわ けであるが、第2の梁12の切込み12a内に接続金具12を嵌め込み、ボルト 16を接続金具13のフック部13aに係止すると、図5に示すように第2の梁 12を第1の梁11に対して仮固定される。First, the second beam 12 is temporarily fixed to the connection fitting 13 fixed to the first beam 11, but the connection fitting 12 is fitted into the notch 12 a of the second beam 12 and the bolt is inserted. When 16 is locked to the hook portion 13a of the connection fitting 13, the second beam 12 is temporarily fixed to the first beam 11 as shown in FIG.
【0011】 次いで、打込みピン1を第2の梁12に穿孔されている孔12cからハンマに より打ち込み、先端部1aが接続金具13の孔、更には第2の梁12の他側の孔 12cに達するまで、かつ後端部1bが第2の梁12の孔12c内に完全に隠れ るまで打ち込む。続いて、残りの3個の孔12cに対しても打込みピン1を打ち 込むことにより、第1、第2の梁11、12同士は接続金具12を介して堅固に 固定されることになる。Next, the driving pin 1 is driven by a hammer from a hole 12c formed in the second beam 12 so that the tip portion 1a is a hole of the connection fitting 13 and a hole 12c on the other side of the second beam 12c. And until the rear end 1b is completely hidden in the hole 12c of the second beam 12. Then, by driving the driving pin 1 into the remaining three holes 12c as well, the first and second beams 11 and 12 are firmly fixed to each other via the connection fitting 12.
【0012】 この際に、打込みピン1の突起1cは第2の梁12内に十分な抵抗力のもとに 喰い込んでいるので、後に至って打込みピン1が緩んで抜け出すことも、内部で 軸心を中心に回転することもない。At this time, since the projection 1c of the driving pin 1 is embedded in the second beam 12 with a sufficient resistance force, the driving pin 1 can be loosened and come out later by the internal shaft. It does not rotate around the heart.
【0013】 また、高所での作業中に打込みピン1を脇に置いても、突起1cの存在のため に、打込みピン1は転がって下方に落下してしまうこともない。Further, even when the driving pin 1 is set aside during the work at a high place, the driving pin 1 does not roll and drop downward due to the existence of the projection 1c.
【0014】[0014]
以上説明したように本考案に係る建築用打込みピンは、木材中に打ち込んでも 突起があるために抵抗が大きく、後に至って緩んだり抜け出す虞れはない。 As described above, the construction driving pin according to the present invention has a large resistance even if it is driven into wood and has a large resistance, and there is no fear that it will later come loose or come out.
