Description
本発明は、木造住宅において、横架材から柱材が抜けるのを防止するホールダウン金物に関するものである。 The present invention relates to a hole-down hardware for preventing a pillar material from coming off from a horizontal member in a wooden house.
木造住宅において、土台や梁等の横架材から柱材が抜けるのを防止する金物として、ホールダウン金物が知られている。
ホールダウン金物は、平板状の固定部材に筒状の係合部材を溶接したものであり、係合部材に挿入したアンカーボルトに引き寄せナットを螺合し、引き寄せナットを締め付けることにより固定する（図４）。
In a wooden house, a hole-down hardware is known as a hardware that prevents a pillar material from falling off a horizontal member such as a base or a beam.
The hole-down hardware is obtained by welding a cylindrical engaging member to a flat fixing member, and is fixed by screwing a pulling nut onto an anchor bolt inserted into the engaging member and tightening the pulling nut (see FIG. 4).
従来のホールダウン金物には、以下のような問題点があった。
（１）引き寄せナットの緩みや締め付け不足により、接合力が弱くなるおそれがある
（２）部品点数が多くなり、施工効率が低い
（３）係合部材を溶接するため、溶接作業の品質よりホールダウン金物の強度品質が不安定になるおそれがある
The conventional hole-down hardware has the following problems.
(1) There is a possibility that the joining force may be weakened due to loosening of the pulling nut or insufficient tightening. (2) The number of parts increases and construction efficiency is low. The strength quality of down hardware may become unstable
本発明は、引き寄せナットの締結が不要であり、部品点数の少なく溶接作業のないホールダウン金物を提供することを目的とする。 It is an object of the present invention to provide a hole-down hardware that does not require fastening of a pulling nut and has a small number of parts and no welding work.
上記目的を達成するためになされた本願の第１発明は、アンカーボルトに螺合する管状の螺合部と、前記螺合部の一方の端部に形成した平板状の固定部とからなり、前記螺合部の中心軸と前記固定部の中心軸が同一線上である、ホールダウン金物を提供する。
本願の第２発明は、第１発明のホールダウン金物において、前記固定部の前記螺合部と逆側の端部の中央に、前記固定部より幅狭の凸部を形成することを特徴とするホールダウン金物を提供する。
1st invention of this application made in order to achieve the said objective consists of the tubular screwing part screwed together to an anchor bolt, and the flat fixing part formed in the one end part of the said screwing part, A hole-down hardware is provided in which the central axis of the screwing portion and the central axis of the fixing portion are on the same line.
The second invention of the present application is characterized in that, in the hole-down hardware according to the first invention, a convex portion narrower than the fixing portion is formed at the center of the end portion of the fixing portion opposite to the screwing portion. Provide hole down hardware.
本発明は、上記した課題を解決するための手段により、次のような効果を得ることができる。
（１）螺合部と固定部を一体としてアンカーボルトに螺合するため、引き寄せナットによる締め付けが不要となる。
（２）引き寄せナットによる締め付けが不要になるため、締め付けにより構造材が変形することがない。
（３）引き寄せナットのナット緩みによる接合力の低下もない。
（４）部品点数が少なく、施工効率が高い。
（５）固定部をプレス加工により形成するため、溶接箇所がなくなり、ホールダウン金物の強度品質が安定する。
The present invention can obtain the following effects by means for solving the above-described problems.
(1) Since the screwing portion and the fixing portion are integrally screwed to the anchor bolt, tightening with a pulling nut is not necessary.
(2) Since the tightening with the pulling nut is not necessary, the structural material is not deformed by the tightening.
(3) There is no reduction in joining force due to loosening of the pulling nut.
(4) The number of parts is small and the construction efficiency is high.
(5) Since the fixed portion is formed by press working, there is no welded portion, and the strength quality of the hole-down hardware is stabilized.
以下、図に示す実施例に基づき、本発明を詳細に説明する。 Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.
［１］ホールダウン金物の構成
（１）全体構成
本発明のホールダウン金物は、鋼管または鋼棒をプレス加工して形成したものである。
本発明のホールダウン金物は、管状の螺合部１と、螺合部１から延びる固定部２と、からなる（図１）。
[1] Configuration of hole-down hardware (1) Overall configuration The hole-down hardware of the present invention is formed by pressing a steel pipe or a steel rod.
The hole-down hardware of the present invention includes a tubular screwing portion 1 and a fixing portion 2 extending from the screwing portion 1 (FIG. 1).
（２）螺合部
螺合部１は鋼管の内部または鋼棒の端部を切削して雌ネジ加工を行ったものである。
本発明のホールダウン金物は、アンカーボルト３に螺合するものであり、螺合部１のサイズもアンカーボルト３に螺合するサイズとする。
(2) Threaded portion The threaded portion 1 is formed by cutting the inside of a steel pipe or the end of a steel rod to perform female threading.
The hole-down hardware of the present invention is to be screwed to the anchor bolt 3, and the size of the screwing portion 1 is also set to be a size to be screwed to the anchor bolt 3.
（３）固定部
固定部２は、鋼管または鋼棒をプレスし平板状にしたものである。
固定部２にはビス孔２１を形成し、ビス孔２１に挿通したビス４により、柱材に固定する。
固定部２をプレス加工により形成するため、溶接箇所がなくなり、ホールダウン金物の強度品質が安定する。
(3) Fixed part The fixed part 2 presses a steel pipe or a steel bar, and makes it flat form.
A
Since the fixing portion 2 is formed by press working, there is no welded portion, and the strength quality of the hole-down hardware is stabilized.
［２］ホールダウン金物の使用状態
次に、本発明のホールダウン金物を使用した構造材５の接合について説明する（図２）。
構造材は、例えば基礎６上に配置する土台５ａとそれに垂直に立設する柱材５ｂである。
[2] Usage state of hole-down hardware Next, the joining of the structural material 5 using the hole-down hardware of the present invention will be described (FIG. 2).
The structural material is, for example, a base 5a arranged on the foundation 6 and a pillar material 5b erected perpendicularly thereto.
（１）ホールダウン金物の螺合
土台５ａから延出するアンカーボルト３にホールダウン金物の螺合部１を螺合し、ホールダウン金物とアンカーボルト３を一体とする。
アンカーボルト３は、柱材５ｂから所定の距離離れた位置にあるため、ホールダウン金物はアンカーボルト３に容易に螺合することができる。
(1) Screwing the hole-down hardware The screw-down portion 1 of the hole-down metal is screwed to the anchor bolt 3 extending from the base 5a, and the hole-down hardware and the anchor bolt 3 are integrated.
Since the anchor bolt 3 is located at a predetermined distance from the column member 5b, the hole-down hardware can be easily screwed into the anchor bolt 3.
（２）固定部の固定
固定部２のビス孔２１にビス４を挿通して、柱材５ｂに固定する。
アンカーボルト３と柱材５ｂは間隔があるが、アンカーボルト３やホールダウン金物の固定部２がしなることにより、ホールダウン金物が柱材５ｂと接触して固定することができる。
本発明のホールダウン金物は本体の螺合部１をアンカーボルト３に螺合して一体とするため、引き寄せナットを使用せず、引き寄せナットの締め忘れがない。また、引き寄せナットを使用しないため、引き寄せナットの緩み、脱落もない。
(2) Fixing of fixing part Screw 4 is inserted into
The anchor bolt 3 and the pillar material 5b are spaced apart from each other, but the anchor bolt 3 and the fixing portion 2 for the hole-down hardware are bent, so that the hole-down hardware can be fixed in contact with the pillar material 5b.
For hold-down hardware of the present invention is an integral by screwing the threaded portion 1 of the body to the anchor bolts 3, drawn without using a nut, not forgetting to fasten the drawn nut. In addition, since the pulling nut is not used, the pulling nut does not loosen or fall off.
［３］その他実施例
（１）凸部の形成
ホールダウン金物は、固定部２の螺合部１と逆側の上端に凸部２２を形成してもよい（図３）。
凸部２２は固定部２より幅狭で、固定工具のソケットに嵌合可能な幅とする。回転工具に取り付けたソケットに凸部２２を嵌合することにより、回転工具により容易にホールダウン金物をアンカーボルト３に螺合することができる。
[3] Other Embodiments (1) Formation of Convex Part The hole-down hardware may form a convex part 22 at the upper end of the fixing part 2 opposite to the screwing part 1 (FIG. 3).
