Description

本考案は、梁やまぐさ等の横架材に関する。   The present invention relates to horizontal members such as beams and lintels.

スチールハウスにおける骨組み構造としては、布基礎上に組まれる柱や、梁、根太、まぐさ等の横架材は、いずれも厚さ、１．０ｍｍ程度の一枚の薄鋼板を、その強度を補強すべくロールフォーミングにより断面コ字形に成形した薄板軽量形鋼やリップ付の薄板軽量形鋼が使用される。
このような薄板軽量形鋼によって横架材を形成する場合、例えば２つの薄板軽量形鋼のウエブどうしを背中合わせに当接し、両ウエブを貫通してドリルねじを打設して両薄板軽量形鋼を結合することにより、横架材の剛性を高めている（例えば非特許文献１）。 As for the frame structure in the steel house, all the horizontal members such as columns, beams, joists and lintels built on the fabric foundation are made of a thin steel sheet with a thickness of about 1.0 mm. A thin lightweight steel with a U-shaped cross section formed by roll forming or a thin lightweight steel with a lip is used for reinforcement.
When a horizontal member is formed of such thin lightweight steels, for example, two thin lightweight steels are brought into contact with each other back to back, and drill screws are driven through both webs to form both thin lightweight steels. Are combined to increase the rigidity of the horizontal member (for example, Non-Patent Document 1).

２階以上で壁が設置される床がまぐさによって支持される場合、まぐさの下側は窓や出入口等の開口部となるので、まぐさの剛性が不足するとまぐさが撓み易くなってしまうという課題がある。
このため、上述したように、複数の薄板軽量形鋼またはリップ付き薄板軽量形鋼をドリルねじにより一体化することで、剛性を高めたまぐさを使用している。 If the floor where the walls are installed on the second floor or higher is supported by the lintel, the lower side of the lintel will be an opening such as a window or doorway, so the lintel will bend easily if the rigidity of the lintel is insufficient. There is a problem of end.
For this reason, as described above, a lintel with increased rigidity is used by integrating a plurality of thin lightweight steel shapes or thin lightweight steel shapes with lips with a drill screw.

しかしながら、まぐさの下側の開口部の大開口化や大スパン化を図る場合、上述した従来のまぐさでは、剛性が不足する虞がある。例えば、従来のまぐさでは、薄板軽量形鋼どうしを結合するために使用されるドリルねじの配置ピッチは３００ｍｍと粗いため構造面での高剛性化は十分なされていない。ドリルねじの配置ピッチを密にすることでまぐさの剛性を高めることは可能であるが、それにも限界がある。   However, when a large opening or a large span of the opening on the lower side of the lintel is intended, the conventional lintel described above may have insufficient rigidity. For example, in the conventional lintel, the arrangement pitch of drill screws used for joining thin lightweight steel shapes is as coarse as 300 mm, so that the structure surface is not sufficiently rigid. Although it is possible to increase the rigidity of the lintel by making the arrangement pitch of the drill screws dense, there is a limit to this.

本考案は、前記事情に鑑みてなされたもので、まぐさ等の横架材の高剛性化を図ることを目的とする。   This invention is made | formed in view of the said situation, and aims at achieving high rigidity of horizontal members, such as a lintel.

前記目的を達成するために、本考案の横架材は、上下方向に重ねられるとともにウエブを面一にして配置された複数段の薄板軽量形鋼を備えた横架材本体と、
複数段の前記薄板軽量形鋼の接合部を跨いで前記ウエブに固定されることで、複数段の前記薄板軽量形鋼を接合する金属製の接合板とを備えたことを特徴とする。 In order to achieve the above object, the horizontal member of the present invention includes a horizontal member body including a plurality of thin lightweight steel plates that are stacked in the vertical direction and arranged with the web being flush with each other,
It is provided with a metal joining plate that joins a plurality of stages of the thin plate lightweight section steel by being fixed to the web across the joint portions of the plurality of stages of the thin sheet lightweight section steel.

本考案においては、横架材本体が上下に重ねられた複数段の薄板軽量形鋼を備え、これら複数段の薄板軽量形鋼の接合部を跨いで接合板がウエブに固定されているので、複数段の薄板軽量形鋼が接合板によって補剛されるともに接合されて一体化される。このため、本考案の横架材は、従来の横架材に比して剛性を高めることができる、つまり高剛性化を図ることができる。   In the present invention, the horizontal frame body is provided with a plurality of thin plate lightweight sections that are stacked one above the other, and the joining plate is fixed to the web across the joints of these plurality of thin sheet lightweight sections. A plurality of thin lightweight steel plates are stiffened and joined together by a joining plate. For this reason, the horizontal member of the present invention can increase the rigidity as compared with the conventional horizontal member, that is, the rigidity can be increased.

本考案の前記構成において、前記横架材本体を構成する各段の前記薄板軽量形鋼は左右一対あり、
これら左右一対の薄板軽量形鋼は両ウエブを外側に向けて接合されていることが好ましい。 In the configuration of the present invention, the thin lightweight steel at each stage constituting the horizontal member main body has a pair of left and right,
The pair of left and right thin lightweight steel plates are preferably joined with both webs facing outward.

このような構成によれば、左右一対の薄板軽量形鋼が両ウエブを外側に向けて接合されているので、横架材本体の各段を構成する左右一対の薄板軽量形鋼が断面矩形状となる。このため、横架材のねじり剛性および曲げ剛性を高めることができる。   According to such a configuration, since the pair of left and right thin lightweight steel is joined with both webs facing outward, the pair of left and right thin lightweight steel constituting each stage of the horizontal member body has a rectangular cross section. It becomes. For this reason, the torsional rigidity and bending rigidity of the horizontal member can be increased.

また、本考案の前記構成において、前記横架材本体を構成する最上段の一対の前記薄板軽量形鋼の上部どうしが上接合材によって接合され、最下段の一対の前記薄板軽量形鋼の下部どうしが下接合材によって接合されていることが好ましい。   Further, in the above-described configuration of the present invention, the upper portions of the pair of thin lightweight steel plates constituting the horizontal member body are joined together by the upper joining material, and the lower portions of the pair of thin lightweight steel plates of the lowest step. It is preferable that the two are joined by the lower joining material.

このような構成によれば、上接合材および下接合材によって、最上段の一対の薄板軽量形鋼の上部どうしおよび最下段の一対の薄板軽量形鋼の下部どうしがそれぞれ接合されており、上下段に配置される薄板軽量形鋼どうしは接合板によって接合されているので、横架材を容易に一体化できる。   According to such a configuration, the upper joint member and the lower joint member join the upper part of the uppermost pair of thin lightweight sections and the lower pair of the lower pair of lightweight sections. Since the thin lightweight steel sections arranged in the lower stage are joined by the joining plate, the horizontal member can be easily integrated.

また、本考案の前記構成において、前記ウエブに固定された前記接合板は前記横架材本体の長手方向の一端部から他端部にかけて延在していてもよい。   Moreover, the said structure of this invention WHEREIN: The said joining plate fixed to the said web may be extended from the one end part of the longitudinal direction of the said horizontal member main body to the other end part.

このような構成によれば、接合板が横架材本体の長手方向の一端部から他端部にかけて延在しているので、横架材の剛性をバランスよく高めることができるとともに、曲げ剛性に優れたものとなる。   According to such a configuration, since the joining plate extends from one end portion to the other end portion in the longitudinal direction of the horizontal member body, the rigidity of the horizontal member can be improved in a well-balanced manner and the bending rigidity can be increased. It will be excellent.

また、本考案の前記構成において、前記ウエブに固定された前記接合板は前記横架材本体の長手方向の一端部側と他端部側とにそれぞれ配置されていてもよい。   Moreover, the said structure of this invention WHEREIN: The said joining plate fixed to the said web may be arrange | positioned at the one end part side and other end part side of the longitudinal direction of the said horizontal body main body, respectively.

このような構成によれば、接合板の材料費を軽減できるとともに、横架材の端部を柱や壁等の構造材に接合した場合に、この接合部において所定のせん断剛性を確保できる。   According to such a configuration, the material cost of the joining plate can be reduced, and when the end portion of the horizontal member is joined to a structural material such as a column or a wall, a predetermined shear rigidity can be secured at the joining portion.

また、本考案の前記構成において、前記ウエブに固定された前記接合板は前記横架材本体の上下方向の幅内の一部に設けられていてもよい。   Moreover, the said structure of this invention WHEREIN: The said joining plate fixed to the said web may be provided in a part within the width | variety of the up-down direction of the said horizontal member main body.

このような構成によれば、接合板を横架本体の上下方向の幅内全体に設ける場合に比して、接合板の材料費を軽減できるとともに、接合板の横架材本体の上下方向の幅内における位置を適宜調整することによって横架材を効率よく補剛できる。   According to such a configuration, it is possible to reduce the material cost of the joining plate as compared to the case where the joining plate is provided in the entire width in the vertical direction of the horizontal body, and the vertical direction of the horizontal material body of the joining plate. The horizontal member can be efficiently stiffened by appropriately adjusting the position within the width.

本考案によれば、上下に重ねられた複数段の薄板軽量形鋼が接合板によって補剛されるともに接合されて一体化されるので、横架材の高剛性化を図ることができる。   According to the present invention, a plurality of thin lightweight steel plates stacked vertically are stiffened and joined together by a joining plate, so that the rigidity of the horizontal member can be increased.
