Description
本発明は、在来の造軸組工法建築物にトラス屋根構造を適用した木造建築物に関するものであり、特に、屋根水平構面の許容せん断耐力についての改良に関する。 The present invention relates to a wooden building to which a truss roof structure is applied to a conventional frame construction method building, and particularly to an improvement in the allowable shear strength of a horizontal roof structure.
木造建築の屋根構造としては、例えば、図４(A)に示すものがある。同図において、梁１０，１２，１４がほぼ平行に設けられており、それらにほぼ直交して梁１６，１８，・・・が設けられている。これらの梁１０〜１８，・・・は、柱２０，２２，２４，２６，・・・によって支えられている。梁１０と梁１６の角部内側には火打ち（筋交い）３０が斜めに設けられており、梁１４と梁１６の角部内側には火打ち３２が斜めに設けられている。梁１６，１８，・・・には、複数の束５４が適宜の間隔で垂直方向に設けられている。束５４の上端に、梁１０，１２，１４の方向に棟木５５，母屋５６が設けられている。そして、これら棟木５５，母屋５６と直交する方向に垂木６０が適宜の間隔で多数設けられている。束５４を、中心から両端の梁１０，１４に向かって長さが順次小さくなるようにすることで、垂木６０に勾配が生じ、これが屋根の勾配となる。 As a roof structure of a wooden building, for example, there is one shown in FIG. 4 (A). In the figure, the beams 10, 12, 14 are provided substantially in parallel, and the beams 16, 18, ... Are provided substantially orthogonal to them. These beams 10-18, ... Are supported by columns 20, 22, 24, 26, .... A flint 30 is diagonally provided inside the corners of the beam 10 and the beam 16, and a flint 32 is diagonally provided inside the corners of the beam 14 and the beam 16. A plurality of bundles 54 are provided in the beams 16, 18, ... In the vertical direction at appropriate intervals. At the upper end of the bundle 54, purlins 55 and purlins 56 are provided in the directions of the beams 10, 12, and 14. A large number of rafters 60 are provided at appropriate intervals in the direction orthogonal to the main building 55 and the main building 56. By making the length of the bundle 54 gradually decrease from the center toward the beams 10 and 14 at both ends, a slope is generated in the rafter 60, which becomes the slope of the roof.
前記垂木６０の上には、野地板（図示せず）が設けられる。また、上述した梁１６，１８，・・・の下側に、天井板が設けられる。これにより、火打ち３０，３２，束５４，棟木５５，母屋５６などの天井裏の部分が、部屋側から見て隠れるようになる。 A field board (not shown) is provided on the rafters 60. Further, a ceiling plate is provided below the beams 16, 18, ... As a result, the attic parts such as the flint 30, 32, the bundle 54, the purlin 55, and the purlin 56 are hidden when viewed from the room side.
これに対し、図４(B)に示すようなトラス構造の屋根ユニットが知られている。同図はフィンクトラスの例で、トラス架構１００は、上弦材１０２，下弦材１０４と、それらを支えるウェブ材１０６によって構成されている。上弦材１０２，下弦材１０４，ウェブ材１０６の接合は、例えばネイルプレート（図示せず）によって行われる。なお、軒の出は図示していないが、必要に応じて設けられる。トラス架構１００は、前記梁１０，１２，１４の方向に、適宜の間隔で多数配置される。このようなトラス架構の例としては、例えば下記特許文献１に開示されたものがある。 On the other hand, a roof unit having a truss structure as shown in FIG. 4B is known. The figure shows an example of a fink truss, and the truss frame 100 is composed of an upper chord member 102, a lower chord member 104, and a web member 106 that supports them. The upper chord member 102, the lower chord member 104, and the web member 106 are joined by, for example, a nail plate (not shown). The eaves are not shown, but they will be provided as needed. A large number of truss frames 100 are arranged in the directions of the beams 10, 12, and 14 at appropriate intervals. As an example of such a truss frame, for example, there is one disclosed in Patent Document 1 below.
ところで、従来は、火打ちやブレースを使用して強度を高め、これによって屋根水平構面の許容せん断耐力を得るようにしていた。これに対し、トラス架構で必要な屋根水平構面の許容せん断耐力を得ることができれば、火打ちやブレースを省略することができるといった利点が生ずる。 By the way, conventionally, the strength is increased by using flint or brace, thereby obtaining the allowable shear strength of the horizontal roof structure. On the other hand, if the allowable shear strength of the roof horizontal structure required for the truss frame can be obtained, there is an advantage that flinting and bracing can be omitted.
本発明は、以上のような点に着目したもので、その目的は、トラス構造の屋根ユニットに対してせん断力を負担させることで、必要な屋根水平構面の許容せん断耐力を得ることである。他の目的は、火打ちやブレースを省略することができる木造建築物を提供することである。 The present invention focuses on the above points, and an object of the present invention is to obtain a required allowable shear strength of a roof horizontal structure by applying a shear force to a roof unit having a truss structure. .. Another purpose is to provide a wooden structure that can omit flint and braces.
本発明のトラス屋根構造は、横架材の上に複数のトラス架構が並列に設けられたトラス屋根構造であって、前記トラス架構の間に転び止めを設けて前記横架材に緊結し、前記トラス架構に直交する内部耐力壁線上に小屋組内耐力壁を設けて前記横架材に緊結し、前記トラス架構の上弦材に構造用合板を止付けることで、水平せん断力が前記トラス架構を介して前記構造用合板に伝達されるようにしたことを特徴とする。 The truss roof structure of the present invention is a truss roof structure in which a plurality of truss frames are provided in parallel on a horizontal member, and a roll stopper is provided between the truss frames to be tightly connected to the horizontal member. By providing a bearing wall inside the hut on the internal bearing wall line orthogonal to the truss frame and binding it to the horizontal member, and fixing the structural plywood to the upper chord member of the truss frame, the horizontal shearing force is applied to the truss frame. It is characterized in that it is transmitted to the structural plywood via the above.
主要な形態の一つによれば、前記トラス架構は、上弦材，ウェブ材，下弦材を含んでおり、前記横架材と前記下弦材及び小屋組内耐力壁との接合をビス又はくぎによって行ったことを特徴とする。他の形態によれば、前記転び止めをねじくぎにより前記横架材に緊結したことを特徴とする。更に他の形態によれば、前記トラス架構の下弦材に天井ボードを止付け、前記水平せん断力が前記下弦材も介して前記天井ボードに伝達されるようにしたことを特徴とする。更には、前記屋根ユニットの上弦材，ウェブ材，下弦材としてツーバイ材を使用したことを特徴とする。 According to one of the main forms, the truss frame includes an upper chord material, a web material, and a lower chord material, and the joint between the horizontal member material and the lower chord material and the bearing wall in the cabin is screwed or nailed. It is characterized by having gone. According to another form, the anti-rolling member is fastened to the horizontal member by a screw nail. According to still another form, the ceiling board is fixed to the lower chord member of the truss frame so that the horizontal shear force is transmitted to the ceiling board through the lower chord member. Further, it is characterized in that a two-by material is used as the upper chord material, the web material, and the lower chord material of the roof unit.
本発明の木造建築物は、前記いずれかのトラス屋根構造に水平せん断力を負担させることで、火打ちないしブレースの少なくとも一方を省略したことを特徴とする。本発明の前記及び他の目的，特徴，利点は、以下の詳細な説明及び添付図面から明瞭になろう。 The wooden building of the present invention is characterized in that at least one of flint and brace is omitted by applying a horizontal shear force to any of the truss roof structures. The above and other objects, features and advantages of the present invention will become clear from the following detailed description and accompanying drawings.
本発明によれば、転び止め，小屋組内耐力壁，構造用合板などを設け、更に木ねじなどを利用して緊結することで、屋根水平構面に作用した水平せん断力が横架材に伝達されるようになり、トラス屋根構造に水平せん断力を負担させることができる。このため、火打ちやブレースを省略することができる。 According to the present invention, the horizontal shear force acting on the horizontal structure surface of the roof is transmitted to the horizontal member by providing a roll-prevention, a bearing wall in the hut, a structural plywood, etc., and further binding them using wood screws or the like. This allows the truss roof structure to bear a horizontal shear force. Therefore, flint and brace can be omitted.
以下、本発明を実施するための形態を、実施例に基づいて詳細に説明する。 Hereinafter, embodiments for carrying out the present invention will be described in detail based on examples.
最初に、図１〜図３を参照しながら、本発明の実施例１について説明する。図１には、本実施例に係る屋根構造の一例が示されている。同図において、トラス屋根構造２００は、平行に設けられた複数の横架材（桁）２０２，２０４，２０６の上に、上述したトラス架構１００が複数配列された構造となっている。トラス架構１００の端の間には、前記横架材２０２，２０６上に転び止め２１０が設けられており、トラス架構１００に直交する内部耐力壁線上（内部の横架材２０４上）には、前記横架材２０４の上に小屋組内耐力壁２２０が設けられている。また、上弦材１０２の上には、構造用合板２３０が複数互い違いに取り付けられており、下弦材１０４には、天井ボードとしてせっこう（石膏）ボード２４０が取り付けられている。加えて、妻面にも、構造用合板２３０が妻面耐力要素として取り付けられている。 First, Example 1 of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 shows an example of a roof structure according to this embodiment. In the figure, the truss roof structure 200 has a structure in which a plurality of the above-mentioned truss frames 100 are arranged on a plurality of horizontal members (girders) 202, 204, 206 provided in parallel. Anti-rolling 210 is provided on the horizontal members 202 and 206 between the ends of the truss frame 100, and on the internal bearing wall line orthogonal to the truss frame 100 (on the internal horizontal member 204). A bearing wall 220 in the cabin is provided on the horizontal member 204. Further, a plurality of structural plywood 230s are alternately attached to the upper chord member 102, and a gypsum board 240 is attached to the lower chord member 104 as a ceiling board. In addition, a structural plywood 230 is also attached to the end face as a end bearing element.
以上の各部のうち、下弦材１０４と横架材２０２，２０６は、例えば矢印ＦＡで示すように、木ねじ（ねじくぎ）の斜め打ち（１か所当たり２本）によって緊結されている。横架材２０４，２０６と転び止め２１０は、例えば矢印ＦＢで示すように、木ねじの斜め打ち（１か所当たり４本）によって緊結されている。上弦材１０２と構造用合板２３０は、例えば矢印ＦＣで示すように、鉄丸くぎによって止付けられている。鉄丸くぎの間隔は、必要な耐力が得られる間隔とし、例えば、７５ｍｍ〜３００ｍｍ間隔とする。下弦材１０４とせっこうボード２４０は、例えば矢印ＦＤで示すように、ビスで止付けられている。ビスの間隔は、必要な耐力が得られる間隔とし、例えば、１５０ｍｍ〜３００ｍｍ間隔とする。 Of the above parts, the lower chord member 104 and the horizontal members 202 and 206 are tightly connected by diagonal striking of wood screws (screws) (two per location), as shown by, for example, arrow FA. The horizontal members 204, 206 and the anti-roll 210 are tied together by diagonal striking of wood screws (4 per location), as shown by, for example, arrow FB. The upper chord member 102 and the structural plywood 230 are fastened by iron nails, for example, as indicated by the arrow FC. The interval between the iron round nails is such that the required yield strength can be obtained, and is, for example, an interval of 75 mm to 300 mm. The lower chord member 104 and the gypsum board 240 are fastened with screws, for example, as indicated by the arrow FD. The interval between the screws is such that the required yield strength can be obtained, for example, an interval of 150 mm to 300 mm.
以上のような構造とした場合、水平せん断力は、図２ないし図３に示すようにトラス屋根構造に伝達する。まず、図２には、矢印ＦＰで示すトラス並列方向の水平せん断力の伝達の様子が示されている。矢印ＦＰで示す水平せん断力は、矢印ＦＰ１で示すように転び止め２１０に伝達し、転び止め２１０から上弦材１０２や下弦材１０４に伝達する。矢印ＦＰ２で示す上弦材１０２に伝達した水平せん断力は、矢印ＦＰ３で示すように、面材である構造用合板２３０に伝達する。妻面でも、同様に、構造用合板２３０に伝達する。一方、矢印ＦＰ４で示す下弦材１０４に伝達した水平せん断力は、矢印ＦＰ５で示すように、面材であるせっこうボード２４０に伝達する。 With the above structure, the horizontal shear force is transmitted to the truss roof structure as shown in FIGS. 2 to 3. First, FIG. 2 shows the state of transmission of the horizontal shear force in the truss parallel direction indicated by the arrow FP. The horizontal shear force indicated by the arrow FP is transmitted to the anti-rolling member 210 as shown by the arrow FP1, and is transmitted from the anti-rolling member 210 to the upper chord member 102 and the lower chord member 104. The horizontal shear force transmitted to the upper chord member 102 indicated by the arrow FP2 is transmitted to the structural plywood 230 which is a face material as shown by the arrow FP3. Similarly, on the wife side, the transmission is transmitted to the structural plywood 230. On the other hand, the horizontal shear force transmitted to the lower chord member 104 indicated by the arrow FP4 is transmitted to the gypsum board 240 which is a face material as shown by the arrow FP5.
一方、図３には、矢印ＦＳで示すトラス並列方向に直交する方向の水平せん断力の伝達の様子が示されている。矢印ＦＳで示す水平せん断力は、矢印ＦＳ１で示すように上弦材１０２に伝達し、更に矢印ＦＳ２で示すように、上弦材１０２から構造用合板２３０に伝達する。一方、矢印ＦＳ３で示す下弦材１０４に伝達した水平せん断力は、矢印ＦＳ４で示すように、面材であるせっこうボード２４０に伝達する。 On the other hand, FIG. 3 shows the transmission of the horizontal shear force in the direction orthogonal to the truss parallel direction indicated by the arrow FS. The horizontal shear force indicated by the arrow FS is transmitted to the upper chord member 102 as shown by the arrow FS1, and further transmitted from the upper chord member 102 to the structural plywood 230 as shown by the arrow FS2. On the other hand, the horizontal shear force transmitted to the lower chord member 104 indicated by the arrow FS3 is transmitted to the gypsum board 240, which is a face material, as shown by the arrow FS4.
このように、本実施例によれば、トラス架構１００と横架材２０２等との緊結を、
ａ，桁行方向に平行な内部耐力壁線には、小屋組内耐力壁２２０を設け、
ｂ，梁間方向に平行な耐力壁線には、トラス架構１００の面内せん断性能により、
屋根水平構面のせん断力を耐力壁線上の横架材２０２等に伝達させる。すなわち、水平せん断力は、上述した鉄丸くぎ，木ねじ，ビスの作用により、トラス架構１００を介して、いずれも構造用合板２３０やせっこうボード２４０に伝達されるようになり、構造用合板２３０やせっこうボード２４０が水平構面として作用するようになる。
As described above, according to the present embodiment, the truss frame 100 and the horizontal member 202 and the like are tightly connected.
a, The internal bearing wall 220 parallel to the girder direction is provided with the internal bearing wall 220.
b. Due to the in-plane shear performance of the truss frame 100, the bearing wall line parallel to the beam-to-beam direction
The shearing force of the roof horizontal structure is transmitted to the horizontal member 202 or the like on the bearing wall line. That is, the horizontal shearing force is transmitted to the structural plywood 230 and the steel board 240 via the truss frame 100 by the action of the iron round nails, wood screws, and screws described above, and the structural plywood 230. The thin board 240 comes to act as a horizontal frame.

(1) For example, the shear data of iron round nails and screws is as shown in Table 1 below.
a. The shear modulus GB of the structural plywood 230 is 40.0 (kN / cm 2 ).

(4) Regarding the Young's modulus of the upper chord member 102 and the lower chord member 104, for example, SPF A class 2 and Young's modulus E = 9600 (N / mm 2 ).
次に、計算式の一例を示す。
(1)屋根水平構面（屋根構造の全体であり、構造用合板２３０の面とせっこうボード２４０の面の合算）を水平投影したときの単位長さ当たりの許容せん断耐力ΔＱa［kN/cm］は、次の数１式による。
(1) Allowable shear strength per unit length when the horizontal roof structure (the entire roof structure, which is the sum of the surface of the structural plywood 230 and the surface of the gypsum board 240) is projected horizontally ΔQa [kN / cm ] Is based on the following equation 1.
以上の計算を行った結果、図１の屋根構造における屋根水平構面のせん断性能は、以下の表３のとおりとなり、法令で要求される基準を満たした適切なものであることが判明している。

(2)トラス架構１００に直交する内部耐力壁線上であって横架材２０４の上に、小屋組内耐力壁２２０を設け、
(3)上弦材１０２の上には鉄丸くぎによって構造用合板２３０を取り付け、下弦材１０４にはビスによってせっこうボード２４０を取り付けている。
(4)以上のような構造とすることで、水平せん断力は、トラス架構１００を介して、いずれも構造用合板２３０やせっこうボード２４０に伝達されるようになる。
(5)これにより、トラス屋根構造に水平せん断力を負担させて計算できるようになる。
(6)従って、トラス屋根構造において、火打ちやブレースを省略することも可能となる。
