Description

本発明は、木質床版の接合構造に関する。 The present invention relates to a joint structure of a wooden deck.

ＣＬＴ（Cross Laminated Timber）床版等の木質床版を複数敷き並べるとともに、木質床版同士をせん断力の伝達可能に接合して床スラブを構成する床構造がある。 There is a floor structure in which a plurality of wooden decks such as CLT (Cross Laminated Timber) decks are laid out and joined to each other so that shear force can be transmitted to form a floor slab.

例えば、特許文献１には、木製部材を複数敷き並べるとともに、隣り合う木製部材の端面にそれぞれ形成された孔に、隣り合う木製部材の両方に渡るように棒状部材を挿入し、この棒状部材が挿入された孔の中に接着剤又は無収縮モルタルを充填することにより、隣り合う木製部材同士を接合して床スラブを構成する木製部材の接合構造が開示されている。 For example, in Patent Document 1, a plurality of wooden members are laid out side by side, and a rod-shaped member is inserted into a hole formed in each end face of the adjacent wooden member so as to extend over both of the adjacent wooden members. A joint structure of wooden members forming a floor slab by joining adjacent wooden members by filling the inserted holes with an adhesive or non-shrink mortar is disclosed.

しかし、この木製部材の接合構造では、隣り合う木製部材の端面にそれぞれ形成された孔に棒状部材を挿入するとともに、棒状部材が挿入された孔の中に接着剤又は無収縮モルタルを充填するといった作業が煩雑となる。 However, in this joint structure of wooden members, a rod-shaped member is inserted into holes formed in the end faces of adjacent wooden members, and an adhesive or non-shrink mortar is filled in the holes into which the rod-shaped members are inserted. The work becomes complicated.

床版１２、１４は、ひき板を並べた層を、ひき板の繊維方向が層毎に直交するように重ねて接着したパネル材であるＣＬＴ（Cross Laminated Timber）により形成された木質の床部材である。 The floor slabs 12 and 14 are wooden floor members formed by CLT (Cross Laminated Timber), which is a panel material in which layers of ground boards are laminated and bonded so that the fiber directions of the ground boards are orthogonal to each layer. Is.

図２及び図４に示すように、スリット２０は、平面視にて床版１２の端面に対して略直交するようにして、床版１２の端部上面に形成されている。スリット２０は、床版１２の上面から、床版１２の厚さ方向略中央の位置まで形成されている。スリット２２は、平面視にて床版１４の端面に対して略直交するようにして、床版１４の端部上面に形成されている。スリット２２は、床版１４の上面から、床版１４の厚さ方向略中央の位置まで形成されている。 As shown in FIGS. 2 and 4, the slit 20 is formed on the upper surface of the end portion of the deck 12 so as to be substantially orthogonal to the end surface of the deck 12 in a plan view.

Is buried. Further, the upper end portion 30 of the joining member 24 is embedded in the top concrete portion 16. The upper end bar 32 may be provided on the top concrete portion 16 as needed. For example, when it is not necessary to take measures to prevent cracks in the top concrete portion 16, reinforcing bars such as the upper end bar 32 may not be provided in the top concrete portion 16. Further, instead of providing the upper end bar 32 in the top concrete portion 16, a welded wire mesh or the like may be embedded in the top concrete portion 16 to prevent cracks in the top concrete portion 16.

充填材２６は、接合部材２４の下端部２８が配置されたスリット２０とスリット２２とに充填し硬化させて、床版１２、１４に接合部材２４の下端部２８を固定している。本例では、トップコンクリート部１６を形成するために打設されたコンクリートの一部を、このコンクリートの打設とともに、接合部材２４の下端部２８が配置されたスリット２０とスリット２２とに充填し硬化させており、この充填したコンクリートを充填材２６としている。 The filler 26 fills and cures the slit 20 and the slit 22 in which the lower end 28 of the joining member 24 is arranged, and fixes the lower end 28 of the joining member 24 to the floor slabs 12 and 14. In this example, a part of the concrete cast to form the top concrete portion 16 is filled into the slit 20 and the slit 22 in which the lower end portion 28 of the joining member 24 is arranged together with the casting of this concrete. It has been hardened, and this filled concrete is used as the filler 26.

An example is shown in which the slit 20 and the slit 22 in which the lower end portion 28 is arranged are filled and the filled concrete is used as the filler 26. However, the slit 20 and the slit in which the lower end portion 28 of the joining member 24 is arranged are shown. The filler to be filled with 22 may be any material as long as it can fix the lower end portion 28 of the joining member 24 to the floor slabs 12 and 14.

例えば、床版１２と床版１４との上面にコンクリートを打設する前に、接合部材２４の下端部２８が配置されたスリット２０とスリット２２とに、エポキシ樹脂系接着剤などの接着剤やモルタル等の充填材を充填してもよい。 For example, before placing concrete on the upper surfaces of the floor slab 12 and the floor slab 14, an adhesive such as an epoxy resin adhesive may be applied to the slit 20 and the slit 22 in which the lower end 28 of the joining member 24 is arranged. It may be filled with a filler such as mortar.

さらに、本実施形態では、図２に示すように、接合部材２４をパンチングメタルにより構成した例を示したが、接合部材２４は、接合部材２４の下端部２８が配置されたスリット２０とスリット２２とに充填される充填材２６、及びトップコンクリート部１６を形成するコンクリートに対し、高い付着性を発揮して高い一体性が得られる板状の部材であればよい。 Further, in the present embodiment, as shown in FIG. 2, an example in which the joining member 24 is made of punching metal is shown, but the joining member 24 has a slit 20 and a slit 22 in which the lower end portion 28 of the joining member 24 is arranged. Any plate-shaped member may be used as long as it exhibits high adhesiveness to the concrete forming the filler 26 and the top concrete portion 16 to be filled in and can obtain high integrity.

接合部材５８の下端面は、梁５２の上フランジ６６上面に溶接等により接合されている。また、床版１２の端面と床版１４の端面との間には、コンクリートＶが充填されている。床版１２の端面と床版１４の端面との間、及び接合部材５８の下端部６２が配置されたスリット５４とスリット５６とには、トップコンクリート部１６を形成するために打設されたコンクリートの一部が、このコンクリートの打設とともに充填されている。 The lower end surface of the joining member 58 is joined to the upper surface of the upper flange 66 of the beam 52 by welding or the like. Further, concrete V is filled between the end face of the floor slab 12 and the end face of the floor slab 14. Concrete cast to form the top concrete portion 16 between the end face of the floor slab 12 and the end face of the floor slab 14 and between the slit 54 and the slit 56 in which the lower end portion 62 of the joining member 58 is arranged. A part of is filled with this concrete casting.

梁５２の上フランジ６６上面には複数のスタッド６８が設けられており、この複数のスタッド６８が、床版１２の端面と床版１４の端面との間に充填されたコンクリートＶ中に埋設されている。これにより、床版１２の端面と床版１４の端面との間に充填され硬化したコンクリートＶと、梁５２との一体化が図られている。また、接合部材５８の中間部６０及び下端部６２がスリット５４からスリット５６へ渡って配置された状態で、接合部材５８の上端部６４は、床版１２の上面と床版１４の上面とから突出し、トップコンクリート部１６に埋設されている。 A plurality of studs 68 are provided on the upper surface of the upper flange 66 of the beam 52, and the plurality of studs 68 are embedded in the concrete V filled between the end face of the deck 12 and the end face of the deck 14. ing. As a result, the concrete V filled and hardened between the end face of the floor slab 12 and the end face of the floor slab 14 and the beam 52 are integrated. Further, in a state where the intermediate portion 60 and the lower end portion 62 of the joining member 58 are arranged from the slit 54 to the slit 56, the upper end portion 64 of the joining member 58 is formed from the upper surface of the floor slab 12 and the upper surface of the floor slab 14. It protrudes and is buried in the top concrete portion 16.

他の構成については、図２と略同じなので、同符号を付すとともに説明を省略する。 Since the other configurations are substantially the same as those in FIG. 2, the same reference numerals are given and the description thereof will be omitted.

また、本実施形態では、図２に示すように、トップコンクリート部１６に接合部材２４の上端部３０を埋設した例を示したが、トップコンクリート部１６に設けられた上端筋３２を、接合部材２４に溶接等によって接合してもよい。 Further, in the present embodiment, as shown in FIG. 2, an example in which the upper end portion 30 of the joining member 24 is embedded in the top concrete portion 16 is shown, but the upper end bar 32 provided in the top concrete portion 16 is used as a joining member. It may be joined to 24 by welding or the like.

以上、本発明の実施形態について説明したが、本発明はこうした実施形態に何等限定されるものでなく、本発明の要旨を逸脱しない範囲において、種々なる態様で実施し得ることは勿論である。 Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention.
