Description

本発明は、バルコニーなどに設置されてデッキを支持するデッキ支持材、デッキおよびデッキ施工方法に関する。 The present invention relates to a deck support member that is installed on a balcony or the like and supports a deck, a deck, and a deck construction method.

従来、デッキ支持材として、両端部に振れ止め具が取り付けられる根太が知られている（特許文献１参照）。根太の両端部には、雌ねじ部を有した振れ止め固定金具が設けられている。振れ止め具は、緩衝材を正面に備えた皿の底部中心にねじ軸を備えてなり、このねじ軸が振れ止め固定金具の雌ねじ部にねじ込まれている。また、ねじ軸には止めナットが螺合しており、止めナットの位置調整によって振れ止め具の根太からの突出量を調整可能である。
この特許文献１に記載の根太は、各振れ止め具の突出量の調整により、その皿の緩衝材を、中空矩形状の固定枠の対向する内壁面に密着させることで、根太が振れないように固定される。 Conventionally, a joist having a steady rest attached to both ends is known as a deck support (see Patent Document 1). At both ends of the joists, steady rest fittings having female screw portions are provided. The steady rest includes a screw shaft at the center of the bottom of a dish provided with a cushioning material on the front surface, and the screw shaft is screwed into the female thread of the steady rest fixing bracket. Further, a lock nut is screwed onto the screw shaft, and the amount of protrusion from the joist of the steady rest can be adjusted by adjusting the position of the lock nut.
The joist described in this Patent Document 1 prevents the joist from shaking by adjusting the amount of protrusion of each steady rest to bring the cushioning material of the dish into close contact with the opposing inner wall surface of the hollow rectangular fixed frame. Fixed to.

ところで、特許文献１に記載の根太では、ねじ軸に対する止めナットの位置調整だけによって振れ止め具の根太からの突出量を調整するため、外気温の変化などによって根太に伸縮変形が生じた場合には、根太の長さ寸法の変化に応じて一定の固定状態を保つことが困難である。
つまり、外気温の温度低下によって根太が縮む場合には、固定枠の内壁面に対する振れ止め具からの押圧力が弱まり、根太自体に位置ずれが生じるおそれがある。このため、根太によってデッキの反りなどの変形を抑制することが困難である。他方、外気温の温度上昇によって根太が伸びる場合には、固定枠の内壁面に過大な押圧力が加えられるおそれがある。 By the way, in the joist described in Patent Document 1, the amount of protrusion from the joist of the steady rest is adjusted only by adjusting the position of the locking nut with respect to the screw shaft. It is difficult to maintain a fixed state according to the change in the length dimension of the joist.
That is, when the joist contracts due to a decrease in the outside air temperature, the pressing force from the steady rest against the inner wall surface of the fixed frame is weakened, and the joist itself may be displaced. For this reason, it is difficult to suppress deformation such as warping of the deck by joists. On the other hand, when the joist extends due to a rise in the outside air temperature, an excessive pressing force may be applied to the inner wall surface of the fixed frame.

本発明の目的は、外気温が変化しても一定の固定状態を保つことができるデッキ支持材、デッキおよびデッキ施工方法を提供することにある。 An object of the present invention is to provide a deck support material, a deck and a deck construction method that can maintain a fixed state even when the outside air temperature changes.

本発明のデッキ支持材は、一対の壁部間に固定されてデッキ材を支持するデッキ支持材であって、前記一対の壁部の対向方向を長手方向として配置される支持本体と、前記支持本体の一方の端部に、前記支持本体の長手方向に沿ってスライド可能に取り付けられるスライド部材と、前記スライド部材を一対の壁部のうちの一方の壁部に向かって付勢するばね部材と、前記支持本体の他方の端部および前記スライド部材のうちの少なくとも一方に取り付けられる長さ調整具と、前記支持本体の他方の端部および前記スライド部材のうちのいずれか他方または前記長さ調整具にそれぞれ取り付けられて前記一対の壁部に当接する一対の当接部材とを備え、前記スライド部材および前記支持本体のうちの一方には、スライド方向に延びた長孔が形成され、前記スライド部材および前記支持本体のうちの他方には、前記長孔にガイドされるガイド体が形成され、前記ガイド体は、前記支持本体に対する前記スライド部材の傾きを抑制可能に前記長孔に挿通されることを特徴とする。 The deck support material of the present invention is a deck support material that is fixed between a pair of wall portions and supports the deck material, and a support main body that is disposed with the opposing direction of the pair of wall portions as a longitudinal direction, and the support A slide member attached to one end of the main body so as to be slidable along the longitudinal direction of the support main body, and a spring member for biasing the slide member toward one of the pair of wall portions; , A length adjuster attached to at least one of the other end of the support body and the slide member, and either the other end of the support body and the slide member or the length adjustment. again and again respectively attached a pair of abutment members abutting on the pair of wall portions, said slide member and said one of the support body, the long hole extending in the sliding direction is formed A guide body guided by the long hole is formed on the other of the slide member and the support body, and the guide body can suppress the inclination of the slide member with respect to the support body. It is characterized by being inserted into .

本発明のデッキ支持材によれば、長さ調整具の長さ調整によってデッキ支持材の全長を調整できるうえ、ばね部材によってスライド部材が一方の壁部に向かって付勢されるため、金属製、樹脂製、木製などの支持本体の長さ寸法が外気温の変化を受けて変化しても、
外気温の変化に対応してスライド部材が支持本体の長手方向に沿ってスライドし、ばね部材が弾性伸縮することで、デッキ支持材の固定状態を一定に保つことができる。つまり、外気温の温度低下によって支持本体が縮む場合には、ばね部材に付勢されるスライド部材が一方の壁部に向かってスライドすることで、デッキ支持材の全長を伸ばすことができ、一対の壁部への固定が位置ズレを生じる程度にまで緩むことを防止できる。また、外気温の温度上昇によって支持本体が伸びる場合には、スライド部材がばね部材の付勢に抗して支持本体の一方の端部に向かってスライドすることで、デッキ支持材の全長を縮めることができ、一対の壁部に過大な押圧力が加えられることを抑制できる。
さらに、長さ調整具の長さ調整によって一対の壁部に対する突っ張り力をも調整できる。
また、長さ調整具が支持本体の他方の端部に取り付けられる場合には、長さ調整具の長さ調整によって支持本体の長手方向における位置を調整でき、設置自由度を拡げることができる。
他方、長さ調整具がスライド部材に取り付けられる備える場合には、デッキ支持材を一対の壁部間に突っ張り固定した状態で長さ調整を行うことで、支持本体の長手方向における位置を維持したままスライド部材の支持本体に対する位置を調整でき、一対の壁部に対する押圧力を調整できる。
加えて、ガイド体が、支持本体に対するスライド部材の傾きを抑制可能に長孔に挿通されるため、スライド部材の支持本体に対する傾きによるデッキ支持材の浮き上がりを抑制できる。
なお、デッキ支持材は、例えば、デッキが固定される根太によって構成される。 According to the deck support material of the present invention, the overall length of the deck support material can be adjusted by adjusting the length of the length adjuster, and the slide member is urged toward the one wall by the spring member. Even if the length of the support body such as resin or wood changes due to changes in the outside air temperature,
The slide member slides along the longitudinal direction of the support body in response to a change in the outside air temperature, and the spring member elastically expands and contracts, whereby the fixed state of the deck support member can be kept constant. That is, when the support main body contracts due to a decrease in the outside air temperature, the slide member biased by the spring member slides toward one wall portion, so that the total length of the deck support material can be extended. Can be prevented from being loosened to the extent that the fixing to the wall portion causes positional displacement. In addition, when the support body is extended due to a rise in outside air temperature, the slide member slides toward one end of the support body against the bias of the spring member, thereby reducing the overall length of the deck support material. It is possible to suppress an excessive pressing force from being applied to the pair of wall portions.
Furthermore, the tension force on the pair of wall portions can be adjusted by adjusting the length of the length adjusting tool.
When the length adjuster is attached to the other end of the support body, the position of the support body in the longitudinal direction can be adjusted by adjusting the length of the length adjuster, and the degree of installation freedom can be expanded.
On the other hand, when the length adjuster is attached to the slide member, the length of the support body is maintained in the longitudinal direction by adjusting the length while the deck support member is stretched and fixed between the pair of wall portions. The position of the slide member relative to the support body can be adjusted as it is, and the pressing force against the pair of wall portions can be adjusted.
In addition, since the guide body is inserted into the long hole so as to suppress the tilt of the slide member with respect to the support body, it is possible to suppress the deck support material from being lifted due to the tilt of the slide member with respect to the support body.
Note that the deck support member is constituted by, for example, joists to which the deck is fixed.

It is preferable that a contact member is attached.
According to such a configuration, the amount of protrusion of the one abutting member with respect to the other end of the support body can be adjusted by adjusting the length of the first length adjustment tool. The second length adjuster can be used for adjusting and adjusting the overall length of the deck support material. On the other hand, the length of the second length adjuster can be adjusted to adjust the amount of protrusion of the other abutting member relative to the slide member. It can be used for adjusting the urging force, and the workability can be improved by properly using each length adjuster. Furthermore, since both the first length adjustment tool and the second length adjustment tool are provided, the adjustment width can be easily increased.

本発明のデッキ支持材では、前記ガイド体は、スライド方向に並んで位置する２本以上のガイド用ビスによって構成されることが好ましい。

According to such a configuration, the configuration of the guide body can be simplified with two or more guide screws, and the two or more guide screws are arranged side by side in the slide direction, so that the inclination of the slide member with respect to the support body is increased. Can be suppressed.

本発明のデッキ支持材では、前記スライド部材には、前記支持本体に対するスライド方向の位置を示す目印が設けられることが好ましい。
このような構成によれば、前述した支持本体に対するスライド方向の位置を示す目印がスライド部材に設けられるため、目印によってスライド部材の支持本体に対するスライド方向の位置を確認しつつスライド部材を位置調整でき、例えば、ばね部材の付勢力を予め定められた設定値に簡単に設定できる。 In the deck support material of the present invention, it is preferable that the slide member is provided with a mark indicating a position in the slide direction with respect to the support body.
According to such a configuration, since the mark indicating the position in the slide direction with respect to the support body is provided on the slide member, the position of the slide member can be adjusted while confirming the position of the slide member in the slide direction with respect to the support body by the mark. For example, the urging force of the spring member can be easily set to a predetermined set value.

本発明のデッキ支持材では、前記支持本体から下方への突出量を調整可能な高さ調整具をさらに備えることが好ましい。
このような構成によれば、支持本体から下方への突出量を調整可能な高さ調整具を備えるため、例えば、デッキ支持材の下部に高さ位置調整用のパネル材などを設置しなくても、高さ調整具によってデッキ支持材の高さ位置を適切な高さ位置に簡単に調整できる。 In the deck support material of the present invention, it is preferable that the deck support material further includes a height adjuster capable of adjusting a downward protrusion amount from the support body.
According to such a configuration, since the height adjustment tool capable of adjusting the downward protrusion amount from the support main body is provided, for example, a panel material for height position adjustment or the like is not installed at the lower portion of the deck support material. However, the height adjustment tool can easily adjust the height position of the deck support material to an appropriate height position.

［デッキの施工］
以下、デッキ１の施工手順について説明する。
先ず、図１に示すように、複数の根太３を間口方向に沿って所定間隔を隔てて配置する。この際、各根太３の長手方向の向きはバルコニー４の出幅方向と同じ向きとされ、当接部材６２はバルコニー４の壁部６側（先端側）に位置し、当接部材７２はバルコニー４の壁部７側（基端側）に位置した状態とされる。また、当接部材７２は、壁部７に当接した状態とされている。
ここで、図２に示すように、バルコニー４の底部５には、壁部７から壁部６に向かって下さがりの傾斜勾配が設定されているので、複数の高さ調整具８０の操作摘み８２をそれぞれ操作して各軸部材８１の下方への突出量を調整して、根太３が水平方向に延びた状態にする。 [Deck construction]
Hereinafter, the construction procedure of the deck 1 will be described.
First, as shown in FIG. 1, a plurality of joists 3 are arranged at predetermined intervals along the frontage direction. At this time, the longitudinal direction of each joist 3 is the same as the protruding width direction of the balcony 4, the contact member 62 is located on the wall 6 side (front end side) of the balcony 4, and the contact member 72 is the balcony 4 is located on the wall 7 side (base end side). The contact member 72 is in contact with the wall 7.
Here, as shown in FIG. 2, the bottom part 5 of the balcony 4 is provided with a downward slope from the wall part 7 toward the wall part 6. Each of the shaft members 81 is adjusted by adjusting each of the shaft members 81 so that the joists 3 extend in the horizontal direction.

次に、長さ調整具６０の長さ調整によって各根太３の全長を調整し、壁部６，７間に仮固定する。つまり、操作ナット６３の回転操作によって軸部材６１の突出量を調整し、当接部材６２を根太本体３０の長手方向に沿って壁部６に向かって突出させ（図６参照）、壁部６に当接させる。つづいて、止めナット６４を回転して固定金具３６の連結板部３６３に当接し、軸部材６１の回転をロックする。このようにして、根太３を壁部６，７間に仮固定する。 Next, the total length of each joist 3 is adjusted by adjusting the length of the length adjuster 60 and temporarily fixed between the wall portions 6 and 7. That is, the protruding amount of the shaft member 61 is adjusted by rotating the operation nut 63, and the contact member 62 is protruded toward the wall portion 6 along the longitudinal direction of the joist body 30 (see FIG. 6). Abut. Subsequently, the locking nut 64 is rotated to come into contact with the connecting plate portion 363 of the fixing bracket 36 to lock the rotation of the shaft member 61. In this way, the joists 3 are temporarily fixed between the wall portions 6 and 7.

次に、長さ調整具７０の長さ調整によって各根太３の壁部６，７に対する突っ張り状態を調整する。つまり、操作ナット７３の回転操作によって軸部材７１の突出量を調整し、スライド部材４０をスライド方向において根太本体３０に向かって接近させ、二つの目印４５間に根太本体３０の端部３０Ｂ側の端面が位置した際に、コイルばね５０の付勢力が予め定められた設定値の範囲内に設定されたとし、止めナット７４を回転してスライド部材４０の連結板部４３に当接して、軸部材７１の回転をロックする。このように、コイルばね５０の付勢力を調整し、根太３の壁部６，７に対する押圧力を調整することで、突っ張り状態を調整する。ここで仮に、長さ調整具７０の長さ調整によってコイルばね５０の付勢力を設定値の範囲内に調整しきれかなった場合には、長さ調整具６０の長さ調整によってコイルばね５０の付勢力を調整してもよい。 Next, by adjusting the length of the length adjuster 70, the tension state of the joists 3 with respect to the wall portions 6 and 7 is adjusted. That is, the amount of protrusion of the shaft member 71 is adjusted by rotating the operation nut 73, the slide member 40 is moved toward the joist body 30 in the sliding direction, and the end 30 B side of the joist body 30 is located between the two marks 45. When the end face is positioned, it is assumed that the urging force of the coil spring 50 is set within a predetermined set value range, and the locking nut 74 is rotated to come into contact with the connecting plate portion 43 of the slide member 40 and the shaft The rotation of the member 71 is locked. Thus, the tension state is adjusted by adjusting the urging force of the coil spring 50 and adjusting the pressing force of the joists 3 against the walls 6 and 7. Here, if the urging force of the coil spring 50 cannot be adjusted within the set value range by adjusting the length of the length adjuster 70, the length of the coil spring 50 can be adjusted by adjusting the length of the length adjuster 60. The biasing force may be adjusted.

次に、複数のデッキ材２を根太３上に載置しながら水平方向に並設し、バルコニー４の出幅方向における両端部に配置されたデッキ材２Ａ，２Ｂを固定ビス８によって根太本体３０の両端部３０Ａ，３０Ｂに固定する。
このようにして、デッキ１をバルコニー４に施工する。 Next, a plurality of deck materials 2 are placed side by side in the horizontal direction while being placed on the joists 3. Are fixed to both end portions 30A and 30B.
In this way, the deck 1 is constructed on the balcony 4.

［本実施形態の効果］
（１）長さ調整具６０，７０を備えるため、根太３の一対の壁部６，７間への設置の際に根太３の全長を調整できるうえ、根太本体３０に対してスライド可能なスライド部材４０と根太本体３０の端部３０Ｂに設けられた固定金具３７との間に介在されるコイルばね５０によって、スライド部材４０が壁部７に向かって付勢されるため、アルミ製の根太本体３０の長さ寸法が外気温の変化を受けて変化しても、この外気温の変化に対応してスライド部材４０が根太本体３０の長手方向に沿ってスライドし、コイルばね５０が弾性伸縮することで、各根太３の固定状態を一定に保つことができる。つまり、外気温の温度低下によって根太本体３０の長さ寸法が縮む場合には、コイルばね５０に付勢されるスライド部材４０が壁部７に向かってスライドすることで、根太３の全長を伸ばすことができ、壁部６，７への固定が位置ズレを生じる程度にまで緩むことを防止できる。また、外気温の温度上昇によって根太本体３０の長さ寸法が伸びる場合には、スライド部材４０がコイルばね５０の付勢に抗して根太本体３０の端部３０Ｂに向かってスライドすることで、根太３の全長を縮めることができ、壁部６，７に過大な押圧力が加えられることを抑制できる。
さらに、長さ調整具６０，７０の長さ調整によって壁部６，７に対する突っ張り力をも調整できる。
また、長さ調整具６０の長さ調整によって根太本体３０の長手方向における位置を調整でき、設置自由度を拡げることができる。
他方、根太３を壁部６，７間に突っ張り固定した状態で、長さ調整具７０による長さ調整を行うことで、根太本体３０の長手方向における位置を維持したままスライド部材４０の根太本体３０に対する位置を調整でき、壁部６，７に対する押圧力を調整できる。
（２）長さ調整具６０の長さ調整によって根太本体３０に対する当接部材６２の突出量を調整できるため、長さ調整具６０を根太本体３０の位置調整や根太３の全長調整用として利用できる。他方、長さ調整具７０の長さ調整によってスライド部材４０に対する当接部材７２の突出量を調整できるため、長さ調整具７０を付勢力調整用として利用できる。このため、長さ調整具６０，７０の使い分けによって施工性の向上を図れる。さらに、長さ調整具６０，７０の双方を備えるため、調整幅の拡大を容易に行うことができる。
（３）連結体５５Ａ，５５Ｂが、根太本体３０に対するスライド部材４０の傾きを抑制可能に長孔４１１，４２１に挿通されるため、スライド部材４０の根太本体３０に対する傾きによる根太３の浮き上がりを抑制できる。
（４）連結体５５Ａ，５５Ｂの構成を２本の段付きビス５５１，５５２によって簡略化でき、段付きビス５５１，５５２がスライド方向に並んで位置するため、スライド部材４０の根太本体３０に対する傾きを抑制できる。
（５）根太本体３０に対するスライド方向の位置を示す目印４５がスライド部材４０に設けられるため、目印４５によってスライド部材４０の根太本体３０に対するスライド方向の位置を確認しつつスライド部材４０を位置調整することで、コイルばね５０の付勢力を予め定められた設定値に簡単に設定できる。
（６）高さ調整具８０が根太本体３０に取り付けられるため、例えば、根太３の下部に高さ位置調整用のパネル材（図示省略）などを設置しなくても、高さ調整具８０によって根太３の高さ位置を適切な高さ位置に簡単に調整できる。
（７）デッキ１の施工において、先ず長さ調整具６０の長さ調整によって根太３の全長を調整して当接部材６２，７２を壁部６，７に当接することで、壁部６，７に大きな押圧力を加えることなく、根太３の固定位置を設定（仮固定）できる。
さらに、長さ調整具７０の長さ調整によってスライド部材４０を根太本体３０に対してスライドさせるため、根太本体３０の位置変化を生じることなく根太３の固定位置を維持したまま、コイルばね５０の付勢力を設定値に設定できる。
このように、長さ調整具６０を根太３の全長調整に用い、長さ調整具７０をコイルばね５０の付勢力の調整に用いることで、施工性を向上できる。 [Effect of this embodiment]
(1) Since the length adjusters 60 and 70 are provided, the total length of the joist 3 can be adjusted when the joist 3 is installed between the pair of wall portions 6 and 7, and the slide is slidable with respect to the joist main body 30. Since the slide member 40 is biased toward the wall portion 7 by the coil spring 50 interposed between the member 40 and the fixing bracket 37 provided at the end 30B of the joist main body 30, the aluminum joist main body Even if the length dimension of 30 changes in response to a change in the outside air temperature, the slide member 40 slides along the longitudinal direction of the joist body 30 in response to the change in the outside air temperature, and the coil spring 50 elastically expands and contracts. Thus, the fixed state of each joist 3 can be kept constant. That is, when the length of the joist main body 30 is reduced due to the temperature drop of the outside air temperature, the slide member 40 biased by the coil spring 50 slides toward the wall portion 7, thereby extending the overall length of the joist 3. It is possible to prevent the fixing to the wall portions 6 and 7 from being loosened to the extent that misalignment occurs. Further, when the length dimension of the joist body 30 is increased due to the temperature rise of the outside air temperature, the slide member 40 slides toward the end 30B of the joist body 30 against the bias of the coil spring 50, The overall length of the joist 3 can be shortened, and an excessive pressing force can be suppressed from being applied to the wall portions 6 and 7.
Furthermore, the tension force with respect to the walls 6 and 7 can be adjusted by adjusting the lengths of the length adjusters 60 and 70.
Moreover, the position in the longitudinal direction of the joist body 30 can be adjusted by adjusting the length of the length adjuster 60, and the degree of freedom in installation can be expanded.
On the other hand, the joist body 3 of the slide member 40 is maintained while maintaining the position of the joist body 30 in the longitudinal direction by adjusting the length with the length adjusting tool 70 in a state where the joist 3 is stretched and fixed between the wall portions 6 and 7. The position with respect to 30 can be adjusted, and the pressing force on the walls 6 and 7 can be adjusted.
(2) Since the protruding amount of the contact member 62 with respect to the joist main body 30 can be adjusted by adjusting the length of the length adjusting tool 60, the length adjusting tool 60 is used for adjusting the position of the joist main body 30 and adjusting the total length of the joist 3. it can. On the other hand, since the protrusion amount of the contact member 72 with respect to the slide member 40 can be adjusted by adjusting the length of the length adjuster 70, the length adjuster 70 can be used for adjusting the biasing force.
