Description

本発明は,ウッドデッキやフローリングの床板であって,幅方向両端面を成す側面に床板の長さ方向にスリットが形成された床板を根太等の支持材上に固定するための床板固定具に関し,特に合成木材製の床板の固定に適した床板固定具に関する。 The present invention relates to a floor plate of the wooden deck and flooring, relates floor fixing device for fixing a floor plate which slit the length of the floor plate to the side surface is formed which forms the width direction both end surfaces on the support member, such as joists, in particular to suitable floor fixtures to fix the synthetic wood made of floorboards.

ウッドデッキを例として説明すると,このウッドデッキの施工は,一例として図7に示すように地表等に必要に応じて基礎を打設する等した設置面9上に束柱6を立設し,この束柱6上に根太等の支持材5を架設し,この支持材5上に床板4であるデッキパネルを,所定間隔を介して一定方向に並行に並べて載置すると共に,この床板4を,前記支持材5に固定することにより行われる。 When described as an example wood deck, construction of the wood deck is erected a Tababashira 6 on equal had installation surface 9 for pouring the foundation if necessary to the surface such as shown in FIG. 7 as an example, the bundle bridged the support 5, such as joists on the pillar 6, the deck panel is a floor plate 4 on the support 5, as well as placed side by side in parallel in a predetermined direction through a predetermined distance, the floor plate 4, said It carried out by fixing to the support member 5.

支持材5に対して床板4を固定する最も簡単な手段としては,図8に示すように床板4の表面から支持材5に至る釘や螺子釘7'を打ち込み,この釘や螺子釘によって床板4を支持材5に直接止め付ける手段がある。 The simplest means for fixing the floor plate 4 with respect to the support member 5, driving the nails and compression screw 7 'extending to the supporting member 5 from the surface of the floor plate 4, as shown in FIG. 8, the floor plate by the nail and compression screw 4 there is a direct stop attaching means to support 5.

しかし,この手段による場合,床板4の表面に釘や螺子釘7'の頭部が露出するために見栄えが悪く,また,経時により釘や螺子釘の頭部が床板4の表面より突出した場合には,床板上を歩行等する際に危険を伴う。 However, if by this means, poor appearance to expose the head of the nail and compression screw 7 'to the surface of the floor plate 4, and if the head of the nail and compression screw protrudes from the surface of the floor plate 4 with time in involves a danger when walking, etc. on the floor.

さらに,一旦施工された床板4は,これを取り外した際,床板4の表面に釘や螺子釘によってうがたれた穴が残ることから,例えば解体された家屋等より回収した使用済みの床板を再利用しようとすれば,この孔を埋める等の煩雑な作業が必要となる。 Further, the floor plate 4, which is once construction, when removed it, since the leaving holes drilled by nails and compression screw on the surface of the floor plate 4, the used floorboards recovered from example dismantled house or the like if you try to re-use, a complicated work such as fill this hole is required.

そこで,図9(A),(B)に示すように釘や螺子釘を床板4の表面に直接打ち込むことなく,床板固定具100,110を使用して支持材5に床板4を取り付ける手段も提案されており,このような床板固定具100,110による取り付けを可能とするために,床板4の幅方向における両端を成す側面40に,床板4の長さ方向に連続したスリット41を形成し,このスリット41に嵌合させた床板固定具100,110を支持材5に固定することで,支持材5に対する床板4の固定を行うことも提案されている。 Accordingly, FIG. 9 (A), the without implanting the nail and compression screw directly to the surface of the floor plate 4 (B), the even means for attaching the floor plate 4 to the supporting member 5 by using the floorboard fixture 100, 110 proposed and, in order to enable attachment by such floorboards fasteners 100 and 110, the side surface 40 forming the opposite ends in the width direction of the floorboards 4, a slit 41 consecutive to the length direction of the floor plate 4 the floorboards fixtures 100 and 110 is fitted into the slit 41 by fixing the supporting member 5, it has also been proposed to perform a fixed floor plate 4 with respect to the support member 5.

このように,床板4を支持材5に固定するために,上端開口縁より外向きに突出したフランジ部101を設けた長尺のチャンネル金具を床板固定具100として使用し,この床板固定具100のフランジ部101を,隣接配置された床板4の対向する側面40に形成されたスリット41内にそれぞれ挿入すると共に,長手方向に所定の間隔で底板に形成された釘孔102に挿入された螺子釘7'をそれぞれ支持材5に打ち込む(ねじ込む)ことで,床板固定具100を介して床板4を支持材5に固定する手段〔図9(A)参照〕,他に,架橋片111と該架橋片111の裏面より突出した中間片112を備えた断面T字状の床板固定具110を使用し,この床板固定具110の架橋片111を床板4のスリット41内に挿入すると共に,中間片 Thus, in order to secure the floor plate 4 to the support member 5, by using the channel bracket elongated having a flange portion 101 that protrudes outwardly from the upper end opening edge as the floorboard fixture 100, the floorboard fixture 100 the flange portion 101, respectively is inserted into the slit 41 formed on the side surface 40 facing the floor plate 4 disposed adjacent the inserted screws nail hole 102 formed in the bottom plate at predetermined intervals in the longitudinal direction driving a nail 7 'by the supporting member 5 (screwed) to the means for fixing the floor plate 4 to the supporting member 5 through the floor plate fixture 100 [see FIG. 9 (a)], otherwise crosslinking piece 111 and the using the T-shaped cross section of the floor plate fixture 110 having an intermediate piece 112 which projects from the back surface of the cross piece 111, is inserted crosslinking piece 111 of the floor plate fixture 110 into the slit 41 of the floor plate 4, intermediate piece 112を同図上下方向に貫通する釘孔113に挿入した螺子釘7'を支持材5に打ち込む(ねじ込む)ことで,床板4を支持材5に固定する手段も提案されている〔図9(B)参照〕。 112 driven into the supporting member 5 the compression screw 7 'inserted into nail hole 113 penetrating in the figure the vertical direction (screwing) that is, means for fixing the floor plate 4 to the support member 5 has also been proposed [9 ( B) reference].

なお,図9(A)を参照して説明した床板固定具100の構造において,更に図10に示すようにフランジ部101の先端に鋸歯状の端縁を有する係止爪103を形成し,螺子釘7'による固定時,係止爪103が床板4のスリット41の内壁に食い込むようにしたものや(特許文献1;図10参照),図9(B)を参照して説明した床板固定具110の構造において,支持材5に対して螺子釘7'を締め込んで行くと変形が生じ,この変形によって床板4に設けたスリット41の内壁との接触抵抗を増大させるようにした床板固定具110も提案されている(特許文献2:図11参照)。 Incidentally, in the structure of the floor plate fixture 100 described with reference to FIG. 9 (A), the form of the locking claw 103 with a serrated edge further the tip of the flange portion 101 as shown in FIG. 10, a screw when fixing with nails 7 ', and those to bite into the inner wall of the slit 41 of the locking claw 103 floor 4 (Patent Document 1; see FIG. 10), floor fixtures described with reference to FIG. 9 (B) in the structure of 110, crowded in going and deformation occurs tighten the compression screw 7 'relative to the support member 5, floorboards fixture so as to increase the contact resistance between the inner wall of the slit 41 provided in the floor plate 4 by the deformation 110 has been proposed (Patent Document 2: see FIG. 11).

前述した床板4の固定手段において,図9(A),(B)を参照して説明した固定手段によれば,床板4を支持材5より上方に引きはがそうとしても,床板4の側面40に形成したスリット41の内壁が,床板固定具100,110のフランジ部101乃至は架橋片111と接触するために,床板4は,支持材5上に固定されてこれを引き剥がすことはできない。 In fixing means floorboards 4 described above, FIG. 9 (A), the according to the fixing means described with reference to (B), even if Hagaso pull upward the floor plate 4 from the support member 5, the side surface of the floor plate 4 the inner wall of the slit 41 formed in the 40, in order to flange 101 of the floor plate fixture 100, 110 is in contact with the crosslinking piece 111, floorboards 4 can not peel it is fixed on the support member 5 .

しかし,このような床板固定具100,110による固定では,床板4と床板固定具100,110間の直接的な連結を行っていないために,床板4を上方に引き剥がせないようにする点では効果的であるものの,床板4の長手方向の移動を規制する力が弱い。 However, fixation by such floorboards fasteners 100 and 110, in order to not make any direct connection between the floor 4 and floor fixtures 100 and 110, that will be prevented pull peeled floorboards 4 upward in although effective, is weak force for restricting the longitudinal movement of the floor plate 4.

そのため,このようにして固定された床板4上を人が歩く等して,床板4を長手方向に移動させる力が加わると床板が長手方向に移動して外れてしまうおそれがあり,例えば床板4の長手方向における両端側に,床板4の端部に突合して床板の移動を規制する横木を設ける等の対策が必要となる。 Therefore, in this way the upper floor 4 fixed by such person walks, there is a risk that the floorboard when force is applied to move the floor plate 4 in the longitudinal direction deviates to move longitudinally, e.g., floor 4 of the both ends in the longitudinal direction, measures such as providing a crosspiece which Tsukiawashi the end of the floor plate 4 to restrict the movement of the floor is required.

しかし,このようにして横木を設けることで床板4の端部が横木を越えて移動できないようにしても,床板4の端部と横木との間には,気温や湿度の変化に伴う床板4の膨張,収縮等を考慮して若干の隙間を設ける必要があるために,人が歩く度に床板4がこの隙間分長手方向に移動して床板4の端部が前述した横木に衝突すれば,この衝突により騒音が発生し,ひいては,ゆがみなどの変形,破損が生ずる。 However, as the end of the floor plate 4 by providing the crosspiece in this way you can not move beyond the crosspiece, between the end and the crosspiece of the floor plate 4, floor 4 with changes in temperature and humidity expansion, in order to take into account the contraction it is necessary to provide a slight gap, floorboards 4 each time a person walks is if collides with rungs end described above floorboards 4 to move into the gap amount longitudinal , noise is generated by this collision, therefore, deformation such as distortion, breakage occurs.

図10に示した特許文献1に記載の床板固定具100にあっては,フランジ部101に設けた係止爪103を床板4のスリット41内壁に食い込ませることで隣接する床板4間を連結しようというものであり(特許文献1の「0055」欄),係止爪103を設けることにより,床板固定具100に「かすがい」に類似した機能を付与しようというものであるが,このような係止爪103を設け,これを床板4に食い込ませた場合には,床板4と床板固定具100とが強固に連結されることとなる結果,この床板固定具100を使用する場合には,床板4が長手方向に移動することも効果的に防止し得るものと考えられる。 In the floor plate fixture 100 described in Patent Document 1 shown in FIG. 10, be ligated between floorboards 4 which are adjacent to bite into the locking claws 103 provided in the flange portion 101 into the slit 41 the inner wall of the floor plate 4 are those that ( "0055" column of Patent Document 1), by providing the locking claws 103, but is that attempts to impart a function similar to the "Kasugai" floor plate fixture 100, such engagement the claw 103 is provided, in a case where it was bitten in the floor 4, as a result of the fact that the floor plate 4 and the floorboard fixture 100 is rigidly connected, when using this floor plate fixture 100, floorboards 4 is thought to also be effectively prevented to move longitudinally.

しかし,床板4,特に合成木材によって形成された床板4は,気温の変化や水分の吸収状態等によって比較的大きな寸法変化を生じ,特に,床板4の長手方向における寸法変化は大きい。 However, the floor plate 4, the floor plate 4 formed by a particular synthetic wood, caused a relatively large dimensional change by the absorption state of change and water temperature, in particular, dimensional change in the longitudinal direction of the floorboard 4 is large. 例えば,6mの木質合成板で,以下のとおりとなる。 For example, in the synthetic wood board of 6 m, composed as follows.

そのため,図10の床板固定具100のように,係止爪103を床板4に食い込ませる等して床板4と床板固定具100とを強固に連結してしまうと,膨張や収縮による床板4の寸法変化を吸収できず,床板固定具100に大きな力が加わって床板固定具100の破損や変形,螺子釘7'の抜け落ちが生じて床板4の固定ができなくなり,また,床板4に反りや歪み等の変形が生じるおそれがある。 Therefore, as the floorboard fixture 100 of FIG. 10, the locking claw 103 when in such cutting into floor 4 thus firmly connect the floorboards 4 and the floorboard fixture 100, floorboards 4 due to expansion and contraction can not absorb the dimensional change, and a large force is applied to the floor board fixture 100 breakage or deformation of the floor plate fixture 100, can no longer be fixed fall off the floor plate 4 caused the compression screw 7 ', also warp Ya the floorboards 4 there is a possibility that deformation such as distortion is caused.

そのため床板固定具には,人が歩行等した際に加わる通常の使用状態においてかかる負荷の程度では床板4の移動を規制して固定することができるが,床板4の膨張や収縮により床板4自体に寸法変化が生じた場合等,床板固定具を破損させてしまう程の大きな力で床板4を動かそうとする力が加わった場合には,床板4の移動を許容し得るように床板4を固定できるものであることが望まれる。 Therefore the floorboards fixture, although the degree of load applied in normal use to be applied when a person walks or the like can be fixed to restrict the movement of the floor plate 4, floor 4 itself due to expansion or contraction of the floor plate 4 in such case the dimensional change has occurred, when a force tending to move the floor plate 4 is applied with a large force enough would defeat the floor plate fixture, a floor plate 4 so as to allow movement of the floor plate 4 it is desired in which can be fixed.

このような要求に対して,図11を参照して説明した特許文献2に記載の床板固定具110にあっては,床板固定具110を樹脂材料等の可撓性材料によって形成し,螺子釘7'の締め込みを行うことにより床板固定具110を変形させて床板4の側面40に設けたスリット41の内壁に対する架橋片111の押圧力を高めて床板4の長手方向への移動を規制することにより,床板4上を人が歩行する等の通常の使用状態で加わる力では床板4が移動することはないが,膨張や収縮等によって床板4の寸法自体が変化した場合のように極めて大きな力が加わった場合には,この寸法変化に伴う床板4の移動を許容することができるように構成している。 For such requirements, in the floor plate fixture 110 described in Patent Document 2 described with reference to FIG. 11, the floor plate fixture 110 formed of a flexible material such as a resin material, compression screw by increasing the pressing force of the bridge piece 111 to deform the floor plate fixture 110 against the inner wall of the slit 41 provided on the side surface 40 of the floor plate 4 to restrict the movement of the longitudinal direction of the floorboards 4 by performing tightening of 7 ' by very large as in the case but floorboard 4 in normal applied in use state force such as walking on floor 4 people will never move, the dimensions of the floor plate 4 itself is changed by expansion or contraction If a force is applied is configured to be able to allow the movement of the floor plate 4 with this dimensional change.

しかし,前掲の特許文献2に記載の床板固定具110では,床板固定具110に変形を生じさせるために,好適な実施形態において中間片112に切欠を形成し,あるいは,架橋板111に厚肉部と薄肉部とを形成する構成を採用する等,その形状が複雑なものとなっている。 However, the floor plate fixture 110 described in Patent Document 2 cited above, to produce a deformation in the floor plate fixture 110, a notch is formed in the intermediate piece 112 in the preferred embodiment, or thick crosslinked plate 111 etc. to adopt a configuration that forms a part and a thin part, it has become a complicated shape.

なお,螺子釘7'の頭部が床板4間に形成された隙間内に隠れるように施工するためには,図9(A)及び図10を参照して説明した床板固定具100では,螺子釘7'として頭部の直径rが床板固定具100に形成された溝幅W1以下のものを使用する必要があり,また,図9(B)及び図11を参照して説明した床板固定具110にあっては,頭部の直径rを,隣接する床板4の側面40間の間隔(以下,この間隔を「目地幅」という。)W2以下の螺子釘を使用する必要がある。 In order to the head of compression screw 7 'is construction so as to be hidden in a gap formed between the floor plate 4, the floor plate fixture 100 has been described with reference to FIGS. 9 (A) and 9 10, screw must use those as nails 7 'diameter r of the head fastener 100 follows the groove width W1 formed in the floor plate, also, and FIG. 9 (B) and floor fixtures described with reference to FIG. 11 in the 110, the diameter r of the head, the spacing between the side surfaces 40 of the adjacent floor plate 4 (hereinafter, this distance called "joint width.") it is necessary to use the W2 following compression screw.

そのため,床板4の目地幅W2を比較的狭く施工しようとすれば,必然的に使用する螺子釘7'の頭部直径rも小さくなるために,ドライバ等の工具からのトルクによって頭部に形成された工具嵌合用の窪みが変形してしまい,その結果螺子釘7'を締め込むことができなくなる。 Therefore, formation if an attempt relatively narrow construction of the joint width W2 of floorboards 4, in order to also small head diameter r of compression screw 7 'to necessarily use, the head by the torque from the tool such as a driver It will be depression deformation of the tool engagement that is, can not be tightened resulting compression screw 7 '.

一方,図9(B)及び図11を参照して説明した床板4の固定において,敢えて目地幅W2に対して頭部の直径rが大きな螺子釘を使用した場合には,この螺子釘7'を締め込む際に,螺子釘7'頭部が床板4の側面40を削り取るために,施工後の見栄えが悪くなり,見栄えを向上させるために螺子釘7'の頭部が削り取った部分をパテ等で埋めて補修等しようとすれば,多大な労力が必要となる。 On the other hand, and FIG. 9 (B) and the reference floorboards 4 have been described with fixed 11, when the dare diameter r of the head relative to the joint width W2 is using large compression screw, the compression screw 7 ' when tightening the, 'to head scraping the sides 40 of the floor plate 4, appearance after construction is poor, compression screw 7 in order to improve the appearance' compression screw 7 putty head scraped portion of the if you try to repair or the like, filled with, etc., it required a great deal of effort.

なお,このように床板4の側面40が削り取られることは,頭部の直径が目地幅に対して小さい螺子釘7'を使用した場合であっても,螺子釘7'が斜めに打ち込まれる等した場合には同様に生じ得るものとなっている。 In this way the side surfaces 40 of the floor plate 4 is cut away, the 'even when using a compression screw 7' diameter of the head is smaller compression screw 7 against the joint width, etc. are implanted obliquely It has become what may occur similarly when.

本発明は,上記従来技術における欠点を解消するためになされたものであり,比較的簡単な構造でありながら,人が床板上を歩行等した場合等,通常の使用状態で生じる外力が床板に加わった場合には,床板の長手方向の移動を規制するが,床板が膨張,収縮することにより寸法変化が生じた場合のように,極めて強固な力によって床板固定具との接触位置を長手方向に移動させようとする力が生じた場合には,このような移動を許容することができる床板固定具を提供することを目的とする。 The present invention has been made to solve the drawbacks of the prior art, relatively with a simple structure, such as when a person walks or the like on the floor, an external force occurring in normal use within floorboards when applied is to restrict the longitudinal movement of the floor, floor expansion, as in the case of dimensional changes caused by shrinkage, the longitudinal contact position between the floor plate fixture by a very strong force force to move is when produced is intended to provide a floor plate fixture can tolerate such movement to.

また,本発明は,上記目的に加え,床板固定具を支持材に固定する螺子釘として頭部の直径が可及的に大きなものを使用することができ,且つ,このような頭部の直径が大きい螺子釘を使用した場合であっても,螺子釘の頭部を床板の表面より突出させることなく,且つ,床板の幅方向における側面を螺子釘の頭部によって削ることなく施工することのできる床板固定具を提供することを目的とする。 The present invention, in addition to the above-described object, as a compression screw for fixing the floor plate fixture support can diameter of the head is to use as much as possible large, and the diameter of such heads even when using a compression screw is large, without the head of the compression screw to protrude from the surface of the floor, and, in that construction without scraping the sides in the width direction of the floorboard by the head of the compression screw and to provide a floor plate fixture capable.

以上で説明した本発明の構成により,本発明の床板固定具1によれば,以下の効果を得ることができた。 The configuration of the present invention described above, according to the floorboard fixture 1 of the present invention, it was possible to obtain the following effects.

架橋片3の裏面側のみならず,上面側にも床板4の側面40に挟持されるスペーサ片2を設けることにより,床板固定具1が断面において十字状〔図1(B)参照〕に形成されていることにより,床板固定具1と床板4との接触面積の増大が得られていると共に,スペーサ片2の側面23に複数の凸条22を設けたことにより,床板固定具1と床板4との接触抵抗を大幅に増大させることができた。 Not back side of the bridge piece 3 only, formed by the even upper surface providing a spacer piece 2 is clamped to the side surface 40 of the floor plate 4, floor fixture 1 is cross-shaped in cross-section [FIG. 1 (B) refer to Fig by being, with increasing the contact area between the floorboard fixture 1 and floor plate 4 is obtained, by providing a plurality of projections 22 on the side surface 23 of the spacer piece 2, the floorboard fixture 1 and floor plate the contact resistance between 4 could be increased considerably.

その結果,床板4と床板固定具1とを直接固定することなく,両者の接触抵抗によって床板4上を人が歩行する等の通常の使用状態において加わる力に対して床板4が長手方向に移動することを十分に防止することができる一方,床板4の膨張や収縮に伴う寸法変化が生じた場合のように,極めて強い力で床板4と床板固定具1との接触位置を移動させようとする力が加わった場合には,床板4の移動を許容することができ,床板の膨張,収縮等に伴う床板固定具1の破損や螺子釘7の脱落,床板4に反りや歪み等の変形が発生することを好適に防止することができた。 Moving Consequently, without fixing the floor plate 4 and the floorboard fixture 1 directly, floor plate 4 against the force exerted in normal use, such a person on the floor plate 4 by the contact resistance therebetween is walking in the longitudinal direction while it is possible to sufficiently prevent that, as in the case of dimensional changes due to expansion or contraction of the floor plate 4 occurs, it attempts to move the contact position between the floorboards 4 and the floorboard fixture 1 in a very strong force when the force is applied may be allowed to move the floor 4, the expansion of the floor, dropping of broken or compression screw 7 floorboards fastener 1 caused by the contraction deformation of the warp and distortion at the floor plate 4 There could be suitably prevented from occurring.

床板固定具1の平面視において,前記凸条22,22'の頂部22aを尖鋭状に形成して,スペーサ片2の側面23を鋸歯状とした構成にあっては,床板4と床板固定具1との接触抵抗を更に増大させることができ,床板4上を人が歩行する等の通常の使用状態における床板4の長手方向における移動を更に確実に防止することができた。 In a plan view of the floorboard fixture 1, the top portion 22a of the projections 22, 22 'formed in a pointed shape, in the side 23 of the spacer piece 2 serrated and the structure, floor 4 and floor fixtures 1 and the contact resistance can be further increased, and it was possible to further reliably prevent the movement in the longitudinal direction of the floorboard 4 in normal use, such that the upper floor 4 person walking.

特に,この凸条22の頂部22aを,凸条22の幅方向における一方側に偏って配置した構成にあっては,床板4の長手方向のいずれか一方向きの移動に対し,より強力に規制することができる床板固定具1を提供することができた。 In particular, the top portion 22a of the projections 22, in the configuration which is disposed biased to one side in the width direction of the ridge 22, with respect to the movement of either one direction of the longitudinal floor 4, more strongly regulated it was to provide a floorboard fixture 1 can be.

架橋片3の下端からスペーサ片2の下端迄の長さlを,床板4の裏面からスリット41の裏面側内壁41a迄の高さLに対して短く形成した場合には,螺子釘によって床板固定具1を支持材5上に取り付けた際,架橋片3の下端がスリットの裏面側内壁41aに対して強固に押圧されることで,膨張,収縮に伴う床板の長手方向への移動を許容しつつ,床板の固定を強固に行うことができた。 If the length l from the lower end of the cross piece 3 until the lower end of the spacer piece 2 was formed shorter from the back of the floor plate 4 with respect to the height L of up to the back surface side inner wall 41a of the slit 41, the floor plate fixed by compression screw whereby upon mounting the tool 1 on the support member 5, by the lower end of the bridge piece 3 is firmly pressed against the back side inner wall 41a of the slit, allowing the expansion, the movement in the longitudinal direction of the floorboard due to shrinkage while, it could be carried out to strengthen the fixing of the floorboards.

表面側における幅方向両端の角部が面取りされて面取り部43が形成された床板4を固定対象とし,前記架橋片3の下端から前記釘孔の形成位置における前記スペーサ片2の上端迄の高さhを,固定対象とする前記床板4の裏面側内壁41aから前記面取り部43の下端43b迄の高さと略同一に形成した床板固定具1にあっては,支持材5に対する床板固定具1の固定に隣接する面取り部43の上端43a間の幅に対して直径rが小さな頭部71を有する皿螺子を使用することで,目地幅W2よりも大きな直径rの頭部71を有する皿螺子を使用することができ,これにより螺子釘7の頭部に形成された工具嵌合用の窪みが破損する等といった問題の発生を減少させることができた。 The floorboards 4 which chamfer 43 is formed corners in the width direction both at the surface side is chamfered and the fixed target, the high from the lower end of the cross piece 3 until the upper end of the spacer piece 2 in the formation position of the nail holes is a a is h, the floorboard fixture 1 from the back side inner wall 41a is formed to a height substantially the same up to the lower end 43b of the chamfered portion 43 of the floor plate 4 to a fixed object, the floorboard fixture 1 to the support member 5 by diameter r of the width between the upper end 43a of the chamfer 43 adjacent to the fixed use dishes screw with a small head 71, pan screw having a head 71 of larger diameter r than joint width W2 the can be used, thereby recess for a tool fitting formed on the head of the compression screw 7 is able to reduce the occurrence of equal problems such damage.

また,このように頭部の直径rが目地幅W2に対して大きな螺子釘7を使用した場合であっても,螺子釘7の頭部71を隣接する面取り部43,43間の間隔に嵌合させることができ,螺子釘7の頭部71が床板4の側面40を削ることなく,且つ,床板4の表面より突出させることなく取り付けることができた。 Moreover, in this way also the diameter r of the head even when using a large compression screw 7 against the joint width W2, fitted to the spacing between the chamfered portions 43 and 43 adjacent the head 71 of the compression screw 7 engaged to it can, the head 71 of the compression screw 7 without scraping the sides 40 of the floor plate 4, and could be attached without protruding from the surface of the floor plate 4.

しかも,螺子釘7の頭部71の傾斜側面71aが面取り部43と接触することにより,床板4との接触抵抗を更に増大させて,通常の使用状態において床板4が移動することを更に確実に防止することができた。 Moreover, by tilting the side surface 71a of the head 71 of the compression screw 7 is in contact with the chamfer 43, to further increase the contact resistance with the floor plate 4, more reliably that the floorboards 4 are moved in the normal use It could be prevented.

なお,図1に示す実施形態にあっては,図1(A)の正面図に示すようにスペーサ片2の上端を中央において高く,幅方向の両端において低くなるように形成し,全体として中央が膨出する丸みを帯びた形状に形成しているが,床板固定具1の形状はこれに限定されず,スペーサ片2の上端をいずれの位置においても均一な高さに形成するものとしても良く,又は,中央部分において高く,幅方向の両端において低い,例えば台形状に形成するものとしても良く,更には,図1(B)における釘孔の上端テーパ部に対応する部分の全部又は一部を切り欠いて,図2(A)に示すように中央部が窪んだ形状に形成しても良い。 Incidentally, in the embodiment shown in FIG. 1, high in the middle of the upper end of the spacer piece 2 as shown in the front view of FIG. 1 (A), was formed to be lower in the both ends in the width direction, the center as a whole Although There has been formed into a rounded shape that bulges, the shape of the floorboard fixture 1 is not limited to this, even those that also formed in uniform height at any position an upper end of the spacer piece 2 well, or high in the central portion, lower in both ends in the width direction may be as forming, for example, trapezoidal shape, further, and FIG. 1 (B) all of the portion corresponding to the upper tapered portion of the nail holes in the or one by notching parts may be formed in a shape recessed central portion as shown in FIG. 2 (a).

また,スペーサ片2の幅方向における両端には,一例として図4に示すように,スペーサ片2の端縁から外向きに広がるV字状の変形部24を設けるものとしても良い。 Further, on both ends in the width direction of the spacer piece 2, as shown in FIG. 4 as an example, it may be those providing the V-shaped deformed portion 24 extending outwardly from the edge of the spacer piece 2.

この変形部24は,床板固定具1の取付前の状態では,最大幅がスペーサ片2の肉厚よりも幅広に形成されているものであっても良いが,取付時には変形して,床板4の側面40が,スペーサ片2の側面との挟持接触を規制しない程度の変形性を有するように形成されている。 The deformation portion 24, the floorboards fastener 1 before being mounted, the maximum width may be one that is formed wider than the thickness of the spacer piece 2, at the time mounting is deformed, floor 4 side 40 of is formed to have a deformability so as not to restrict the clamping contact with the side surface of the spacer piece 2.

以上のように形成されたスペーサ片2は,平面視において略長方形に形成された架橋片3の幅方向における中央においてこの架橋片3と交わっており,床板固定具1が全体として図1(B)に示した側面断面図に表れているように十字状に形成されている。 Spacer piece 2 formed as described above is intersects with the cross piece 3 at the center in the width direction of the bridge piece 3 which is formed in a substantially rectangular shape in a plan view, FIG. 1 (B Overall floorboard fixture 1 ) on the side surfaces are formed in a cross shape as appear in cross-sectional view illustrating.

この架橋片3は,床板4の側面40に形成されたスリット41に挿入可能なものであれば,全体が一定の厚みとなるように図2に示すように平坦な形状に形成するものとしても良く,又は,図1に示すように周縁部にリブを備えた形状としても良く,更には,前述したスペーサ片と同様の凸条を架橋片3の床板4との接触する部分に設けるものとしても良い。 The crosslinking piece 3, as long as it can be inserted into the slit 41 formed on the side surface 40 of the floor plate 4, even as forming the flat shape as shown in FIG. 2 as a whole becomes constant thickness well, or it may be shaped with a rib on the periphery as shown in FIG. 1, as further provided with similar ridges and spacers piece described above to the contact portions of the floor plate 4 of the cross piece 3 it may be.

スペーサ片2の下端から架橋片3の下端迄の高さl〔図1(A),(B)参照〕は,固定対象とする床板4の裏面からスリット41の床板裏面側内壁41a迄の高さL〔図5(A)参照〕と同一,好ましくは,これよりも若干低く形成することが好ましい。 Height l from the lower end of the spacer piece 2 up to the lower end of the cross piece 3 [FIG. 1 (A), (B) refer] is from the back surface of the floor plate 4 of the fixed target until the floor plate back surface side inner wall 41a of the slit 41 high identical to the L [FIG 5 (a)], the preferred are preferably formed slightly lower than this.

なお,架橋片3の最大厚さ,図1の実施形態では架橋片3の周縁部の厚さは,床板4の側面40に形成されたスリット41の幅と同一幅に形成して,架橋片3がスリット41内に圧嵌されるようにしても良く,又はスリット41の幅に対して薄く形成して,スリット41内に遊嵌されるように構成しても良い。 The maximum thickness of the cross piece 3, the thickness of the peripheral portion of the bridge piece 3 in the embodiment of Figure 1, and a width identical to the width of the slit 41 formed on the side surface 40 of the floor plate 4, cross pieces 3 may be configured to be press fit into the slit 41, or formed thinner than the width of the slits 41 may be configured to be loosely fitted in the slit 41.

なお,架橋片3は,床板4の側面40間でスペーサ片2を挟持した際に,スリット41の最奥部に存在する内壁と干渉しないサイズに形成する。 Incidentally, the crosslinking piece 3, when sandwiching the spacer piece 2 between the side surface 40 of the floor plate 4 is formed to a size that does not interfere with the inner wall existing in the deepest portion of the slit 41.

以上のように形成された床板固定具1は,螺子釘7を使用して支持材5に固定され,好ましくはこの螺子釘7として皿螺子を使用して支持材5に固定される。 Floorboard fixture 1 formed as described above is fixed to the support member 5 by using the compression screw 7 is preferably fixed to the support member 5 by using countersunk screws as this compression screw 7.

この床板固定具1の固定に使用する螺子釘7は,支持材5に対する打ち込み深さを確保することができるようスペーサ片2の全高に対して長く形成されていると共に,頭部71以外の部分を,スペーサ片2に形成された釘孔21に挿入することができる太さに形成されている。 Compression screw 7 to be used for fixing the floorboard fixture 1, together with the formed long relative to the total height of the spacer piece 2 to be able to secure a depth implantation for support 5, portions other than the head 71 and it is formed in a thickness that can be inserted into a nail hole 21 formed in the spacer piece 2.

〔使用方法及び作用〕 [Usage and operation]
以上のように構成された本発明の床板固定具1は,図5(A),(B)に示すように,隣接配置する床板4の対向する側面40にそれぞれ形成されたスリット41内に架橋片3を挿入すると共に,床板4の側面40がスペーサ片2の側面23と接触するように,床板4の側面40間でスペーサ片2を挟持する。 Floorboard fixture 1 of the present invention configured as described above, FIG. 5 (A), the (B), the crosslinking in the slit 41 formed respectively on the side surface 40 facing the floor plate 4 to be arranged adjacent is inserted pieces 3, the side surface 40 of the floor plate 4 is in contact with the side surface 23 of the spacer piece 2, clamping the spacer piece 2 between the side surface 40 of the floor plate 4.

床板固定具1が図4に示す変形部24を有する場合には,この変形部24の変形により床板4の側面40がスペーサ片2の側面23に対して押圧接触されるように床板4間の間隔を調整する。 If the floorboard fixture 1 has a deformation portion 24 shown in FIG. 4 is a side 40 of the floor plate 4 is between floorboards 4 to be pressed in contact against the sides 23 of the spacer piece 2 by the deformation of the deformable portion 24 to adjust the interval.

この作業により,床板4間に形成される目地幅W2が,スペーサ片2の肉厚によって一定幅に位置決めされ,目地幅W2が揃った美しい状態で床板4を敷設することができる。 This work, joint width W2 formed between the floor plate 4 is positioned in a predetermined width by the thickness of the spacer piece 2, it is possible to lay the floor plate 4 beautiful state joint width W2 are aligned.

この状態で釘孔21内に挿入した螺子釘7を支持材5に打ち込んでいくと,スペーサ片2の下端が支持材5上に押圧されると共に,架橋片3の裏面がスリット41の裏面側内壁41a上に押圧され,これにより床板4は,床板固定具1を介して支持材5上に固定される。 As it by implanting compression screw 7 inserted into the nail hole 21 in this state the support member 5, the lower end of the spacer piece 2 is pressed on the support member 5, the rear surface side of the back surface of the bridge piece 3 is slit 41 is pressed onto the inner wall 41a, thereby floorboards 4 are fixed on the support member 5 via the floorboard fixture 1.

このようにして床板4を,根太等の支持材5の配置間隔に対応して床板4の長手方向に所定間隔,一例として450mm程度の間隔で複数箇所固定する。 Thus the floor 4, the longitudinal direction at a predetermined interval corresponding to the arrangement interval of the support 5, such as joists floor 4, a plurality of positions fixed at intervals of about 450mm as an example.

床板固定具1は,床板4に対して釘や螺子釘,接着剤等によって直接固定せず,前述した架橋片3の裏面とスリット41の床板裏面側内壁41aとの押圧接触と,床板4の側面40とスペーサ片2の側面との押圧接触によって床板を固定した状態となっているが,前述した床板固定具1の構造により,従来技術として説明したT字状の固定具〔図9(B)参照〕に比較して,スペーサ片2が架橋片3の上方にも存在することにより,床板4の側面40と床板固定具1との接触面積の増大が得られ,これにより接触抵抗の増大が得られるものとなっている。 Floorboard fixture 1, a nail and compression screw relative to the floor plate 4, not fixed directly by such as an adhesive, a pressure contact with the floor plate back surface side inner wall 41a of the rear surface and the slit 41 of the cross piece 3 described above, the floor plate 4 While in a state of fixing the floor plate by the pressing contact with the side surfaces 40 and the spacer piece 2, the structure of the floorboard fixture 1 described above, explained as the prior art T-shaped fixture [FIG 9 (B ) compared to the reference], by spacer pieces 2 are also present above the cross piece 3, the increase in contact area between the side surface 40 and the floor plate fixture 1 floor plate 4 is obtained, thereby increasing the contact resistance It has become a thing that can be obtained.

しかも,スペーサ片2の側面23には,図5の実施形態において,該スペーサ片の上下方向を長さ方向とする凸条,従って,前記床板4の側面のスリット長手方向に対して直交方向を成す凸条22が形成されているために,スペーサ片2の側面23と床板4の側面40との接触抵抗も増大している。 Moreover, the side surface 23 of the spacer piece 2, in the embodiment of FIG. 5, ridges and longitudinal in the vertical direction of the spacer piece, thus, the orthogonal direction to the slit longitudinal side of the floor plate 4 to ridges 22 are formed which form the contact resistance between the side surface 23 and the side surface 40 of the floor 4 of the spacer piece 2 is also increasing.

更に,床板固定具1の固定に,前述したように目地幅W2よりも大径の頭部71を有する皿螺子7を使用する場合には,この皿螺子7を締め込んでいくと皿螺子の頭部71に設けられた傾斜側面71aが床板4の上端角部に形成された面取り部43に接触・押圧されることとなるために,この皿螺子の頭部71における傾斜側面71aと床板4との接触抵抗によっても床板4の移動が規制されている。 Furthermore, the fixed floor panel fastener 1, when using a pan screw 7 having a head 71 of larger diameter than the joint width W2 as described above, the pan screw As you tighten the pan screw 7 in order to be an inclined side surface 71a provided on the head portion 71 is contact and pressed against the chamfered portion 43 formed on the upper corner portion of the floor plate 4, the inclined side surface 71a and the floor plate 4 in the head 71 of the pan screw movement of the floor plate 4 is restricted by the contact resistance with the.

更に,スペーサ片2の幅方向における両端に,V字状の変形部24を設けた構成にあっては,この変形部24が弾性復帰しようとする力によって床板4の側面40に押圧されていると共に,床板4が長手方向に移動しようとした際に,床板と共にその先端部が移動しようとするために,いずれか一方の変形部24が外向きに広がろうとするために,床板4の側面40に対する接触抵抗が更に増大する。 Further, at both ends in the width direction of the spacer piece 2, in the configuration in which the deformation portion 24 of the V-shape, is pressed against the side surface 40 of the floor plate 4 by the force the deformation portion 24 is to elastic return with, when the floor plate 4 attempts to move in the longitudinal direction, in order to be moved the distal end with the floorboard, for one of the deformation portion 24 is going to spread outward, the side surface of the floor plate 4 further increase the contact resistance to 40.

そのため,床板4と床板固定具1との接触状態は,床板4上を人が歩行等した場合のように,通常の使用状態で加わる力に対しては,床板4が移動しないように固定するに十分な力を発生する。 Therefore, contact between the floor 4 and the floorboard fixture 1, as in the case of the upper floor plate 4 person walks, etc., against the force exerted in normal use, fixed to the floor plate 4 is not moved to generate a sufficient force.

一方,例えば床板4が気温や湿度の変化に伴って膨張,収縮することにより,床板4の寸法自体が変化して,床板固定具1との接触位置を移動させようとする極めて強い力が生じた場合には,床板4と床板固定具1とは前述したように釘や螺子釘,接着剤等による直接的に固着は行われていないために,床板4の移動を許容し得るものとなっている。 On the other hand, for example, the floor plate 4 is inflated with a change in temperature and humidity, by shrinking the dimensions of the floor plate 4 itself is changed, cause very strong force to move the contact position between the floor plate fixture 1 when the can is assumed that nails or compression screw as described above and the floor plate 4 and the floorboard fixture 1, in order to directly affixed by adhesive or the like is not performed, may allow movement of the floor plate 4 ing.

その結果,床板4のこのような膨張,収縮に伴う寸法変化が生じても,床板固定具1が破損し,床板固定具1を支持材5に固定する螺子釘7が外れ,更には,床板4に反りや歪み等の変形が生じることを好適に防止することができる。 As a result, such expansion of the floorboards 4, even if the dimension change due to contraction occurs, the floorboard fixture 1 is damaged, out-compression screw 7 for securing the floorboard fixture 1 to the support member 5 is, furthermore, floorboards it is possible to suitably prevent 4 that deformation such as warping or distortion occurs in.

なお,図2に示したように,尖鋭状頂部22aを凸条22の幅方向のいずれか一方寄りに偏って配置した凸条22を備える床板固定具1にあっては,この床板固定具1の凸条22が床板4の側面に対して図6(A),(B)に示すように接触しているものとすると,この床板固定具1が床板4の移動を規制しようとする力は,図6(B)に矢印B方向に移動しようとする床板4を規制する場合に比較して,図6(A)に記載した矢印A方向に移動しようとする床板4を規制する力の方が強くなる。 Incidentally, as shown in FIG. 2, in the a pointed shaped top 22a to the floorboard fixture 1 comprises a ridge 22 arranged biased toward either one deviation in the width direction of the ridge 22, the floorboard fixture 1 Figure 6 projections 22 with respect to the side surface of the floor plate 4 (a), when it is assumed that the contact (B), the force the floorboard fixture 1 is to restrict the movement of the floor plate 4 is , in comparison with the case of regulating the floor plate 4 to be moved in the direction of arrow B in FIG. 6 (B), towards the force for regulating the floor plate 4 to be moved in the direction of arrow a described in FIGS. 6 (a) It becomes stronger.

すなわち,上記の例において,図6(A)に示すように床板4が図中矢印Aの方向に移動する場合,可撓性材料によって形成された床板固定具1の凸条22は,頂部22aが床板4の移動に引かれて図中矢印aに示すように,外向きに広がるように変形する。 That is, in the above example, ridges 22 of Figure 6 when the floorboards 4, as shown in (A) is moved in the direction of the arrow in the figure A, the floorboard fixture 1 which is formed by a flexible material, the top 22a There, as shown in FIG arrow a drawn to the movement of the floor plate 4, it is deformed so as to spread outwardly. その結果,この凸条22の変形によって床板4の側面40との接触抵抗は増大する。 As a result, the contact resistance between the side surface 40 of the floor plate 4 by the deformation of the projections 22 is increased.

一方,図6(B)に示すように,床板4が図中矢印B方向に移動する場合,可撓性材料によって形成された床板固定具1の凸条22は,頂部22aが床板4の移動に引かれて図中矢印bに示すように,内向きに狭まるように変形する。 On the other hand, as shown in FIG. 6 (B), if the floorboards 4 are moved in the drawing direction of the arrow B, the floorboard fixture 1 which is formed by a flexible material projections 22, moving the top portion 22a of the floor plate 4 drawn into, as shown in FIG arrow b, deformed to narrow inwardly. その結果,上記形状の凸条22を設ける場合,床板固定具1は,矢印B方向へ移動しようとする床板4に対し,矢印A方向に移動しようとする床板4の移動をより強固に規制する。 As a result, when providing the ridge 22 of the shape, floorboard fixture 1 is to floorboards 4 to be moved in the arrow B direction, more strongly restrict the movement of the floor plate 4 to be moved in the direction of arrow A .

以上のように,図2に示した床板固定具1にあっては,向きによって床板4の移動に対する規制力が異なることから,例えば図6(C)に示すように床板4の長手方向における所定間隔毎に,床板固定具1(1a〜1d)を,例えば交互に逆向きとなるように配置して,床板4が図6(A)中矢印A方向に移動しようとしたときには,床板固定具1a,1cにより,逆に図6(B)中の矢印B方向に移動しようとした場合には床板固定具1b,1dにより強固に移動を規制する作用を発揮させて,床板4が長手方向のいずれの方向に対しても移動しないようにしても良い。 As described above, in the floorboard fixture 1 shown in FIG. 2, a predetermined since the regulating force different to the movement of the floor plate 4, for example in the longitudinal direction of the floorboards 4, as shown in FIG. 6 (C) depending on the direction at intervals, the floorboard fixture 1 (1 a to 1 d), for example, alternately arranged so as to be opposite, when the floorboards 4 attempts to move in the direction of arrow a 6 (a) is floorboards fixture 1a, the 1c, conversely FIG 6 (B) in the arrow B direction floorboard fixture if it tries to move in 1b, by exerting an effect of regulating the strongly moved by 1d, floor 4 a longitudinal it may not be moved to any of the direction.

また,例えば図6(D)に示すように,床板4の長手方向の一端を横木等に突合させてその移動を規制した状態で,この横木から離間する方向への床板4の移動に対する規制力が大きくなるように床板固定具1(1a,1b)を取り付けるようにしても良く,このように構成する場合には,床板4の一端が常に横木に突合した状態に維持される。 For example, as shown in FIG. 6 (D), the longitudinal end of the floor plate 4 while restricting its movement by butted rungs etc., regulating force to the movement of the floor plate 4 in the direction away from the rail becomes large so that the floorboard fixture 1 (1a, 1b) may be attached to, when such a configuration is maintained in a state where one end of the floor plate 4 is always Tsukiawashi rungs.

なお,図6(D)に示したように床板4及び床板固定具1(1a,1b)を取り付ける場合には,予期せざる大きな力が床板4に加わる等して万が一にも床板4が横木より離間する方向に移動してしまった場合であっても,床板4を,一端を横木に突合させた原位置に自動的に復帰させることができる。 Incidentally, the floor plate 4 and the floorboard fixture 1 (1a, 1b) when mounting the can floor 4 to chance unexpected large force to such applied to the floor 4 rungs, as shown in FIG. 6 (D) even if you've moved in a direction more away, the floor plate 4, one end can be automatically returned to the original position that has butted rungs.

すなわち,図6(E)に示すように,一端が横木から離間した状態にある床板4が膨張して寸法を増大するように変形した場合,床板固定具1bに対して床板固定具1aの方が移動を規制する力が弱い。 That is, as shown in FIG. 6 (E), if the floor 4 in a state in which one end is separated from the crosspiece is deformed so as to increase the size and expansion, towards the floor plate fixture 1a relative to the floorboard fixture 1b but a force for restricting the movement is weak. そのため,床板4は図6(E)中に破線で示すように横木側の端部を横木に近付けるように膨張する。 Therefore, the floor plate 4 expands the ends of the crosspiece side closer to rungs as indicated by the broken line in FIG. 6 (E).

一方,床板4が収縮して寸法を減少する場合には,床板固定具1aに比較して床板固定具1bの規制力が弱いために,床板は,同図中右側の端部を縮めるように変形する結果,床板4の膨張,収縮に伴って床板4が自ら横木と突合した原位置(施工時の位置)に自動で復帰させることもできる。 On the other hand, if the floorboard 4 decreases the size and contraction, compared to the floorboard fixture 1a due to weak regulating force floorboards fastener 1b, floorboards, so as to reduce the end portion of the right side in the figure deforming a result, the expansion of the floor plate 4, is floor 4 with the shrinkage may be returned automatically to his rail and Tsukiawashi original position (position during construction).
