Description

本発明は、住宅等の建物の建物躯体を構成する建築構造材の接合構造に関する。   The present invention relates to a joint structure of building structural materials constituting a building frame of a building such as a house.
近年、住宅等の建物として、長期間の構造的耐久性を有しつつ、居住空間の可変性を有した、所謂、スケルトン・インフィル住宅が知られている(例えば、特許文献1参照)。
スケルトンとは、住宅の柱や梁や床等の建物躯体部分を意味し、インフィルとは、スケルトンの内側の住宅間取り全体を含む内装・設備等を意味する。
スケルトン・インフィル住宅は、スケルトンとインフィルとを構造的に分離した構成とし、スケルトンを高強度に構築して、長期間の耐久性を有するようにするとともに、間取りや内装・設備等を、可変性を有するように構成したものである。
したがって、スケルトン・インフィル住宅は、長年に亘って居住することができ、かつ居住者のライフスタイルや家族構成の変化に応じて、あるいは居住者の多様なニーズに合わせて、比較的容易に改装することが可能である。
In recent years, as a building such as a house, a so-called skeleton infill house having long-term structural durability and a changeable living space is known (for example, see Patent Document 1).
A skeleton means a building frame such as a pillar, a beam, or a floor of a house, and an infill means interior / equipment including the entire house layout inside the skeleton.
Skeleton infill housing has a structure in which the skeleton and infill are structurally separated, and the skeleton is constructed with high strength so that it has long-term durability, and the layout, interior, and facilities are variable. It is comprised so that it may have.
Skeleton-in-fill residences can therefore live for many years and are relatively easily refurbished in response to changes in the resident's lifestyle and family structure or to the diverse needs of the resident It is possible.
特開平2008−050832号公報JP 2008-050832 A
例えば枠組壁工法や在来軸組工法等の既存の構造は、柱や梁あるいは耐力壁等の建築構造材で、屋根や床等の上部構造の荷重や積載荷重を支持するように構成されている。
ところで、スケルトン・インフィル住宅は、上述のように長期間の耐久性を有するものとしなければならない。ところが、既存の構造における柱や梁、耐力壁等の建築構造材では、スケルトン(以下、建物躯体)を高強度に構築するための十分な強度を得られない場合がある。
For example, existing structures such as the frame wall construction method and conventional shaft construction method are constructed to support the loads and loading loads of the superstructure such as roofs and floors with building structures such as columns, beams or bearing walls. Yes.
By the way, a skeleton infill house must have long-term durability as described above. However, building structures such as columns, beams, and load-bearing walls in existing structures may not have sufficient strength to build a skeleton (hereinafter referred to as a building frame) with high strength.
本発明の課題は、建物躯体の長期的な耐久性を実現する高強度な建築構造材の接合構造を提供することを目的とする。   An object of the present invention is to provide a high-strength building structure joining structure that realizes long-term durability of a building frame.

According to invention of Claim 1, the said building structural material 20 is a pair of rod-shaped members 21 and 21 arrange | positioned at predetermined intervals in the direction orthogonal to a longitudinal direction, and these pair of rod-shaped members 21, 21 is a belly panel formed of a wooden panel 23 having a frame 24 formed by assembling vertical and horizontal eaves 24a into a rectangular frame shape, and a face member 25 affixed to both sides of the frame 24. Since the material 22 is provided, the strength of the abdomen 22 itself can be secured. Furthermore, since the high-strength abdomen 22 is provided so as to be sandwiched between the pair of rod-shaped members 21 and 21, for example, the building structure material 20 having a higher strength than the building structure material 20 formed only by the abdomen 22. Can be obtained.
Further, the side end portion of the beam 3 formed by horizontally arranging the building structural material 20 is connected to the upper end portion of the pillar 2 formed by vertically arranging the building structural material 20, and the rod-shaped members 21 are connected to each other. 30, the rod-shaped member 21 of the building structural material 20 for the pillar 2 and the rod-shaped member 21 of the building structural material 20 for the beam 3 can be firmly coupled, and Thus, the building structure material 20 for the pillar 2 and the building structure material for the beam 3 can be reliably and firmly joined.
And the building frame 1 which can support the load and loading load of superstructures, such as a roof and a floor, reliably and fully by joining high-strength building structure materials 20 reliably and firmly in this way. Since it can comprise, it becomes possible to implement | achieve maintenance of long-term durability of the building frame 1. FIG.
また、前記梁3用の建築構造材20の一対の棒状部材21,21のうち、上方に位置する棒状部材21は、前記柱2用の建築構造材20の上端面に載置されており、下方に位置する棒状部材21は、前記柱2用の建築構造材20の棒状部材21の側面に取り付けられているので、前記上方に位置する棒状部材21と、前記柱2用の建築構造材20とを梁勝ち納まりとすることができ、前記下方に位置する棒状部材21と、前記柱2用の建築構造材20とを柱勝ち納まりとすることができる。

At the same time, a second bolt 33 embedded and fixed in the other square member 21a is inserted into the connection box 31, and a second nut 36 inserted from the opening 31a is screwed into the second bolt 33 and tightened. The bar-shaped member 21 positioned below the building structure material 20 for the pillar 2 and the side surface of the bar-shaped member 21 of the building structure material 20 for the column 2 can be firmly connected.
また、前記梁3となる建築構造材20の棒状部材21の先端には、先端面および先端部外周面を覆う座金38が設けられているので、この座金38によって前記棒状部材21の先端を外側から補強できる。
また、座金38は、角材21aの端部の保護や緩み防止の機能を発揮するので、直立する柱2,2間に架設される状態の梁3の安定的な取付状態を維持できることとなる。
Further , since a washer 38 is provided at the tip of the bar-shaped member 21 of the building structure material 20 to be the beam 3 so as to cover the tip surface and the outer peripheral surface of the tip portion, the tip of the bar-shaped member 21 is moved outward by the washer 38. Can be reinforced from.
Further, since the washer 38 functions to protect the end of the square member 21a and prevent loosening, the washer 38 can be maintained in a stable mounting state between the upright columns 2 and 2.
