Description

本発明は、例えば、浴室やプールサイド等に設けられている排水用の溝の上部開口を覆うグレーチングとその設置方法およびグレーチング用のスペーサに関する。   The present invention relates to a grating that covers an upper opening of a drainage groove provided in a bathroom, a poolside, or the like, a method for installing the grating, and a spacer for grating.

従来、この種のグレーチングとしては例えば、図３３，図３４に示すように、溝１１０の上部開口面を覆うものがある。このグレーチング１１２は、複数の並設されたバー部材１１３と、これら複数のバー部材１１３を連結する複数の連結部材１１４とを有している。尚、バー部材１１３はその長手方向Ａが溝１１０の幅方向Ｂと同じになるように並べられている。   Conventionally, as this type of grating, for example, there is one that covers the upper opening surface of the groove 110 as shown in FIGS. The grating 112 includes a plurality of bar members 113 arranged in parallel and a plurality of connecting members 114 that connect the plurality of bar members 113. The bar members 113 are arranged so that the longitudinal direction A thereof is the same as the width direction B of the groove 110.

バー部材１１３は両端に端部開口部１１５を有している。また、連結部材１１４は、端部開口部１１５に嵌着するキャップ部１１６と、隣接する連結部材１１４のキャップ部１１６と連結するための連結用突片１１７とを有している。   The bar member 113 has end openings 115 at both ends. In addition, the connecting member 114 includes a cap portion 116 that fits into the end opening 115 and a connecting protrusion 117 for connecting to the cap portion 116 of the adjacent connecting member 114.

これによると、連結部材１１４のキャップ部１１６をバー部材１１３の端部開口部１１５に嵌着し、連結用突片１１７を隣接する連結部材１１４のキャップ部１１６に差し込むことにより、複数本のバー部材１１３が複数個の連結部材１１４を介して連結される。   According to this, a plurality of bars can be obtained by fitting the cap portion 116 of the connecting member 114 into the end opening 115 of the bar member 113 and inserting the connecting protrusion 117 into the cap portion 116 of the adjacent connecting member 114. The member 113 is connected through a plurality of connecting members 114.

尚、上記のようなグレーチング１１２は例えば下記特許文献１に記載されている。   The grating 112 as described above is described in, for example, Patent Document 1 below.

実用新案登録第３０２９２３０号Utility model registration No. 3029230

しかしながら上記の従来形式では、バー部材１１３毎に連結部材１１４を設けているため、多数のバー部材１１３を連結するには、バー部材１１３の本数に応じて多数の連結部材１１４が必要となり、グレーチング１１２の組立作業に多大な手間を要するという問題がある。   However, in the above conventional type, since the connecting member 114 is provided for each bar member 113, in order to connect a large number of bar members 113, a large number of connecting members 114 are required according to the number of the bar members 113, and the grating is performed. There is a problem that much labor is required for the assembly work 112.

また、図３３に示すように、バー部材１１３の長さＬが長くなると、バー部材１１３の長手方向Ａにおける中央部分に、上方から荷重が作用した場合、隣り合うバー部材１１３間の間隔１１８が変化し易いといった問題がある。   Further, as shown in FIG. 33, when the length L of the bar member 113 is increased, when a load acts on the central portion in the longitudinal direction A of the bar member 113 from above, the interval 118 between the adjacent bar members 113 is increased. There is a problem of being easy to change.

本発明は、組み立てが容易であり、また、バー部材間の間隔の変化を防止することができるグレーチングとその設置方法およびグレーチング用のスペーサを提供することを目的とする。   An object of the present invention is to provide a grating that can be easily assembled and can prevent a change in the interval between bar members, a method for installing the grating, and a spacer for the grating.

上記目的を達成するために、本第１発明は、溝の上部開口面を覆うグレーチングであって、
複数の並設されたバー部材と、これら複数のバー部材を連結する連結部材とを有し、
バー部材は両端部に端部開口部を有し、
連結部材は、取付部と、取付部上に取り付けられた複数の挿入部とを有し、
これら挿入部は、バー部材の配列方向において並べられ、バー部材の端部開口部に挿入可能であるものである。 In order to achieve the above object, the first invention is a grating covering the upper opening surface of the groove,
A plurality of bar members arranged side by side, and a connecting member that connects the plurality of bar members;
The bar member has end openings at both ends,
The connecting member has an attachment portion and a plurality of insertion portions attached on the attachment portion,
These insertion portions are arranged in the arrangement direction of the bar members and can be inserted into the end openings of the bar members.

これによると、連結部材は取付部上に複数の挿入部を有しているため、各挿入部を各バー部材の端部開口部に挿入することにより、複数のバー部材を一括してまとめて連結部材で連結することができる。これにより、連結部材の個数を減らすことができ、グレーチングを容易に組み立てることができる。   According to this, since the connecting member has a plurality of insertion portions on the attachment portion, the plurality of bar members are collectively gathered by inserting each insertion portion into the end opening of each bar member. It can connect with a connection member. Thereby, the number of connecting members can be reduced, and the grating can be easily assembled.

本第２発明におけるグレーチングは、挿入部は、先端ほど縮小するテーパー部を有し、テーパー部から端部開口部に挿入可能であるものである。
これによると、連結部材の挿入部をテーパー部からバー部材の端部開口部に挿入することにより、挿入部が端部開口部内に圧入され、挿入部とバー部材の端部とがテーパー部の楔作用によって強固に接合される。 In the grating according to the second aspect of the invention, the insertion portion has a tapered portion that decreases toward the tip, and can be inserted from the tapered portion into the end opening.
According to this, by inserting the insertion portion of the connecting member from the tapered portion into the end opening of the bar member, the insertion portion is press-fitted into the end opening, and the insertion portion and the end of the bar member are inserted into the tapered portion. It is firmly joined by the wedge action.

本第３発明におけるグレーチングは、バー部材は、下端が開放されたバー溝を、全長にわたり有し、
端部開口部はバー溝の両端部に開口するものである。 In the grating according to the third aspect of the present invention, the bar member has a bar groove whose lower end is opened over its entire length,
The end openings are open at both ends of the bar groove.

本第４発明におけるグレーチングは、連結部材はその長手方向において伸縮自在であるものである。
これによると、連結部材を長手方向において伸縮させることにより、バー部材間の間隔およびグレーチングの長さを調節することができる。 In the grating according to the fourth aspect of the present invention, the connecting member is extendable in the longitudinal direction.
According to this, the space | interval between bar members and the length of grating can be adjusted by expanding / contracting a connection member in a longitudinal direction.

本第５発明におけるグレーチングは、連結部材はバー部材の長手方向において円弧形状に湾曲可能であるものである。
これによると、溝がカーブ（湾曲）している場合、連結部材を溝のカーブに沿って湾曲させることができ、これにより、溝のカーブ部分にグレーチングを容易に設置することができる。 In the grating according to the fifth aspect of the invention, the connecting member can be bent in an arc shape in the longitudinal direction of the bar member.
According to this, when the groove is curved (curved), the connecting member can be curved along the groove curve, whereby the grating can be easily installed in the curved portion of the groove.

本第６発明におけるグレーチングは、隣り同士のバー部材間に所定の間隙が形成され、
バー部材の上面に複数の滑り止め用の凸部又は凹部が形成され、
凸部又は凹部はバー部材の長手方向において所定ピッチおきに位置しているものである。 In the grating according to the sixth invention, a predetermined gap is formed between adjacent bar members,
A plurality of anti-slip convex portions or concave portions are formed on the upper surface of the bar member,
The convex portions or concave portions are located at predetermined pitches in the longitudinal direction of the bar member.

これによると、滑り止め用の凸部又は凹部を形成したことにより、バー部材の上面を通る人や物が滑るのを防止することができる。また、凸部又は凹部は、バー部材の長手方向において所定ピッチおきに位置しているため、バー部材の大まかな長さを把握するための目盛の役目を果たす。これにより、溝の実際の幅寸法が正規の寸法（設計寸法）と若干違っていても、凸部又は凹部を目安にしてバー部材の端部を切断し、バー部材の長さを溝の実際の幅寸法に合うように微調整することが容易に行える。   According to this, by forming the anti-slip convex portion or concave portion, it is possible to prevent a person or an object passing through the upper surface of the bar member from slipping. Moreover, since the convex part or the recessed part is located at predetermined pitch intervals in the longitudinal direction of the bar member, it serves as a scale for grasping the approximate length of the bar member. As a result, even if the actual width dimension of the groove is slightly different from the normal dimension (design dimension), the end of the bar member is cut using the convex or concave portion as a guideline, and the length of the bar member is set to the actual length of the groove. It can be easily fine-tuned so as to fit the width dimension.

本第７発明は、上記第１発明から第６発明のいずれか１項に記載のグレーチングの設置方法であって、
挿入部を端部開口部に挿入して、複数のバー部材を連結部材で連結し、
溝の上部両側に形成された一対の段付部に連結部材を設置するものである。 The seventh aspect of the present invention is a method for installing a grating according to any one of the first to sixth aspects of the present invention,
Insert the insertion portion into the end opening, connect the plurality of bar members with the connecting member,
A connecting member is installed on a pair of stepped portions formed on both upper sides of the groove.

これによると、グレーチングを組み立てて容易に溝に取り付けることができる。この場合、バー部材は連結部材を介して溝の段付部上に支持されるため、溝の段付部からバー部材の上面までは連結部材を含んだ高さになる。   According to this, the grating can be assembled and easily attached to the groove. In this case, since the bar member is supported on the stepped portion of the groove via the connecting member, the height including the connecting member is from the stepped portion of the groove to the upper surface of the bar member.

本第８発明は、上記第１発明から第６発明のいずれか１項に記載のグレーチングの設置方法であって、
挿入部をバー部材の端部開口部に挿入して、複数のバー部材を連結部材で連結し、
連結部材を溝の上部両側に形成された一対の段付部よりもさらに内側へ移動させ、
バー部材の端部を溝の段付部に設置するものである。 The eighth invention is the method of installing a grating according to any one of the first to sixth inventions,
Insert the insertion portion into the end opening of the bar member, connect the plurality of bar members with a connecting member,
Move the connecting member further inward than the pair of stepped portions formed on both sides of the upper part of the groove,
The end of the bar member is installed in the stepped portion of the groove.

これによると、グレーチングを組み立てて容易に溝に取り付けることができる。この場合、バー部材は、連結部材を介さずに、直接に溝の段付部上に支持される。これにより、溝の段付部からバー部材の上面までは連結部材を含まない高さになるため、溝の段付部からバー部材の上面までの高さを低く抑えることができ、床面から溝の段付部までの深さが浅い場合でも対応できる。   According to this, the grating can be assembled and easily attached to the groove. In this case, the bar member is directly supported on the stepped portion of the groove without using the connecting member. As a result, since the height from the stepped portion of the groove to the upper surface of the bar member does not include the connecting member, the height from the stepped portion of the groove to the upper surface of the bar member can be kept low. Even when the depth to the stepped portion of the groove is shallow, it can be handled.

本第９発明は、複数の並設されたバー部材と、これら複数のバー部材を連結する連結部材とを有し、溝の上部開口面を覆うグレーチングに設けられるスペーサであって、
隣り合うバー部材の下端に当て付けられる本体部と、隣り合うバー部材間に挿入されてバー部材間の間隔を維持する間隔維持部と、バー部材の浮き上がりを防止する浮上り防止手段とを有するものである。 The ninth invention comprises a plurality of bar members arranged side by side and a connecting member for connecting the plurality of bar members, and is a spacer provided in the grating covering the upper opening surface of the groove,
It has a main body part applied to the lower end of adjacent bar members, an interval maintaining part that is inserted between adjacent bar members to maintain an interval between the bar members, and a lift preventing means for preventing the bar members from being lifted Is.

これによると、隣り合うバー部材間にスペーサの間隔維持部を挿入することにより、間隔維持部がバー部材間に挟まれ、バー部材間の間隔を所定の間隔に維持することができる。このため、バー部材に、上方から荷重が作用した場合でも、隣り合うバー部材間の間隔が変化するのを防止することができる。また、浮上り防止手段によって、バー部材の浮き上がりを防止することができる。   According to this, by inserting the spacer interval maintaining portion between the adjacent bar members, the interval maintaining portion is sandwiched between the bar members, and the interval between the bar members can be maintained at a predetermined interval. For this reason, even when a load acts on the bar member from above, it is possible to prevent the interval between adjacent bar members from changing. Further, the bar member can be prevented from being lifted by the lift preventing means.

本第１０発明は、複数の並設されたバー部材と、これら複数のバー部材を連結する連結部材とを有し、溝の上部開口面を覆うグレーチングに設けられるスペーサであって、
複数のバー部材の下端に当て付けられる本体部と、隣り合うバー部材間に挿入されてバー部材間の間隔を維持する間隔維持部と、バー部材間の間隔が圧縮される方向に複数のバー部材と間隔維持部とを締め付けて結合する締結手段とを有するものである。 The tenth aspect of the present invention is a spacer provided on a grating that has a plurality of bar members arranged in parallel and a connecting member that connects the plurality of bar members and covers the upper opening surface of the groove,
A main body portion that is applied to the lower ends of the plurality of bar members, a spacing maintaining portion that is inserted between adjacent bar members and maintains a spacing between the bar members, and a plurality of bars in a direction in which the spacing between the bar members is compressed. Fastening means for fastening and joining the member and the interval maintaining part is provided.

これによると、隣り合うバー部材間にスペーサの間隔維持部を挿入することにより、間隔維持部がバー部材間に挟まれ、バー部材間の間隔を所定の間隔に維持することができる。このため、バー部材に、上方から荷重が作用した場合でも、隣り合うバー部材間の間隔が変化するのを防止することができる。   According to this, by inserting the spacer interval maintaining portion between the adjacent bar members, the interval maintaining portion is sandwiched between the bar members, and the interval between the bar members can be maintained at a predetermined interval. For this reason, even when a load acts on the bar member from above, it is possible to prevent the interval between adjacent bar members from changing.

また、締結手段によって、バー部材間の間隔が圧縮される方向に複数のバー部材と間隔維持部とが締め付けられるため、間隔維持部とバー部材とが圧接され、バー部材間の間隔を確実に所定の間隔に維持することができる。   Further, since the plurality of bar members and the interval maintaining portion are tightened in the direction in which the interval between the bar members is compressed by the fastening means, the interval maintaining portion and the bar member are pressed against each other, and the interval between the bar members is ensured. It can be maintained at a predetermined interval.

以上のように本発明によると、グレーチングを容易に組み立てることができ、また、バー部材間の間隔の変化を防止することができる。   As described above, according to the present invention, the grating can be easily assembled, and the change in the interval between the bar members can be prevented.

突起部２４は、挿入部２３を端部開口部１２に挿入したバー部材７の端部間の間隔を維持するための部材であり、隣り合う挿入部２３間に設けられている。
一方の接合部２５は、挿入部２３のテーパー部２８と、逆Ｔ形状の接合凸部３１とを有している。また、他方の接合部２６は、挿入部２３の挿入部本体２７と、逆Ｔ形状の接合凹部３２とを有している。図１１に示すように、接合凸部３１は接合凹部３２に挿脱自在であり、接合凸部３１を接合凹部３２に挿入することにより、互いに隣接する連結部材８の端部同士が接合される。この際、一方の接合部２５のテーパー部２８と他方の接合部２６の挿入部本体２７とが接合することにより、連結部材８同士の端部接合部分にも、挿入部本体２７とテーパー部２８とを有する挿入部２３が形成される。 The protruding portion 24 is a member for maintaining the interval between the end portions of the bar member 7 in which the insertion portion 23 is inserted into the end portion opening portion 12, and is provided between the adjacent insertion portions 23.
One joint portion 25 has a tapered portion 28 of the insertion portion 23 and a reverse T-shaped joint convex portion 31. The other joint portion 26 includes an insertion portion main body 27 of the insertion portion 23 and an inverted T-shaped joint recess 32. As shown in FIG. 11, the joint convex portion 31 can be inserted into and removed from the joint concave portion 32, and the end portions of the connecting members 8 adjacent to each other are joined by inserting the joint convex portion 31 into the joint concave portion 32. . At this time, the taper portion 28 of the one joint portion 25 and the insertion portion main body 27 of the other joint portion 26 are joined, so that the insertion portion main body 27 and the taper portion 28 are also formed at the end joint portion between the connecting members 8. Is formed.

次に、第２の連結部材８ｂの構成を説明するが、上記第１の連結部材８ａと同じ構成を有する部材については、同一の符号を付して、詳細な説明を省略する。
図１２〜図１５に示すように、第２の連結部材８ｂは、曲線部用の連結部材であって、連結部材８ｂの長手方向Ｅに伸縮自在であるとともに、バー部材７の長手方向Ａ（すなわち第２の連結部材８ｂの幅方向）において円弧形状に湾曲可能であって（図１３の仮想線参照）、帯板状の取付部３７と、取付部３７上に取り付けられた複数の挿入部２３と、取付部３７の一端部に設けられた一方の接合部２５と、取付部３７の他端部に設けられた他方の接合部２６とを有している。 Next, the configuration of the second connecting member 8b will be described, but members having the same configuration as the first connecting member 8a are denoted by the same reference numerals, and detailed description thereof is omitted.
As shown in FIGS. 12-15, the 2nd connection member 8b is a connection member for curved parts, Comprising: It can be expanded-contracted to the longitudinal direction E of the connection member 8b, and the longitudinal direction A ( That is, it can be curved in an arc shape in the width direction of the second connecting member 8b (see the phantom line in FIG. 13), and has a strip-shaped attachment portion 37 and a plurality of insertion portions attached on the attachment portion 37. 23, one joining portion 25 provided at one end of the attaching portion 37, and the other joining portion 26 provided at the other end of the attaching portion 37.

取付部３７は、連結部材８ｂの長手方向Ｅにおいて分割された複数の分割取付片３８と、これら分割取付片３８間に設けられた可変結合部材３９とを有している。各挿入部２３はそれぞれ各分割取付片３８上に取り付けられている。   The attachment portion 37 includes a plurality of divided attachment pieces 38 divided in the longitudinal direction E of the connecting member 8b, and a variable coupling member 39 provided between the divided attachment pieces 38. Each insertion portion 23 is mounted on each divided mounting piece 38.

図１６に示すように、可変結合部材３９は、分割取付片３８同士を結合する柔軟性のある変形自在な部材であり、分割取付片３８の厚さよりも薄い逆Ｖ形状の結合片３９ａ，３９ｂを有している。可変結合部材３９が長手方向Ｅに伸縮することにより、連結部材８ｂが長手方向Ｅに伸縮自在となり、さらに、可変結合部材３９の変形により、連結部材８ｂがバー部材７の長手方向Ａにおいて円弧形状に湾曲可能となる（図１３の仮想線参照）。   As shown in FIG. 16, the variable coupling member 39 is a flexible and deformable member that couples the divided mounting pieces 38, and has inverted V-shaped coupling pieces 39 a and 39 b that are thinner than the thickness of the divided mounting pieces 38. have. When the variable coupling member 39 expands and contracts in the longitudinal direction E, the connecting member 8b can expand and contract in the longitudinal direction E. Further, due to the deformation of the variable coupling member 39, the connecting member 8b has an arc shape in the longitudinal direction A of the bar member 7. (See the phantom line in FIG. 13).

以下、上記構成における作用を説明する。
溝２の直線部分２ａにグレーチング１を設置する場合、第１の連結部材８ａの挿入部２３をバー部材７の端部開口部１２に挿入して、複数のバー部材７を一対の連結部材８ａで連結することにより、グレーチング１を組み立てる。その後、図１，図３に示すように、両連結部材８ａを溝２の段付部３に設置することにより、グレーチング１を溝２に取り付けることができる。 Hereinafter, the operation of the above configuration will be described.
When installing the grating 1 in the straight portion 2a of the groove 2, the insertion portion 23 of the first connecting member 8a is inserted into the end opening 12 of the bar member 7, and the plurality of bar members 7 are connected to the pair of connecting members 8a. Assemble the grating 1 by connecting them together. Thereafter, as shown in FIGS. 1 and 3, the grating 1 can be attached to the groove 2 by installing both connecting members 8 a in the stepped portion 3 of the groove 2.

この際、図７に示すように、一本の連結部材８ａは取付部２２上に複数の挿入部２３を有しているため、各挿入部２３を各バー部材７の端部開口部１２に挿入することにより、複数のバー部材７を一括してまとめて連結部材８ａで連結することができる。これにより、連結部材８ａの本数を減らすことができ、グレーチング１を容易に組み立てることができる。   At this time, as shown in FIG. 7, since one connecting member 8 a has a plurality of insertion portions 23 on the attachment portion 22, each insertion portion 23 is connected to the end opening portion 12 of each bar member 7. By inserting, the plurality of bar members 7 can be collectively connected by the connecting member 8a. Thereby, the number of the connection members 8a can be reduced, and the grating 1 can be assembled easily.

また、挿入部２３をテーパー部２８から端部開口部１２に挿入することにより、端部開口部１２が挿入部２３で閉塞されて、挿入部２３が端部開口部１２内に圧入され、挿入部２３とバー部材２８の端部とがテーパー部２８の楔作用によって強固に接合される。これにより、挿入部２３とバー部材２８とを接着する接着剤を不要にすることも可能である。   Further, by inserting the insertion portion 23 into the end opening 12 from the tapered portion 28, the end opening 12 is closed by the insertion portion 23, and the insertion portion 23 is press-fitted into the end opening 12 and inserted. The portion 23 and the end of the bar member 28 are firmly joined by the wedge action of the tapered portion 28. Thereby, it is possible to eliminate the need for an adhesive that bonds the insertion portion 23 and the bar member 28.

尚、挿入部２３は孔部２９を形成したことにより弾性変形し易くなり、このため、挿入部２３を端部開口部１２内に容易に挿入することができる。
また、溝２のカーブ部分２ｂ（曲線部分）にグレーチング１を設置する場合、第２の連結部材８ｂの挿入部２３をバー部材７の端部開口部１２に挿入して、複数のバー部材７を一対の連結部材８ｂで連結することにより、グレーチング１を組み立てる。その後、図２，図３に示すように、両連結部材８ｂを溝２の段付部３に設置する。この際、図１３の仮想線で示すように、バー部材７の長手方向Ａにおいて相対向する一対の連結部材８ｂを溝２のカーブに沿って湾曲させることができ、これにより、溝２のカーブ部分２ｂにグレーチング１を容易に設置することができる。 The insertion portion 23 is easily elastically deformed by forming the hole portion 29, and therefore, the insertion portion 23 can be easily inserted into the end opening portion 12.
Further, when the grating 1 is installed in the curved portion 2b (curved portion) of the groove 2, the insertion portion 23 of the second connecting member 8b is inserted into the end opening portion 12 of the bar member 7, and the plurality of bar members 7 are inserted. Are connected by a pair of connecting members 8b to assemble the grating 1. Thereafter, as shown in FIGS. 2 and 3, both connecting members 8 b are installed in the stepped portion 3 of the groove 2. At this time, as shown by phantom lines in FIG. 13, the pair of connecting members 8 b facing each other in the longitudinal direction A of the bar member 7 can be curved along the curve of the groove 2. The grating 1 can be easily installed in the portion 2b.

また、図４，図６に示すように、バー部材７に第１および第２凸部１５，１６を形成したことにより、バー部材７の上面を通る人や物が滑るのを防止することができる。また、第１凸部１５は、バー部材７の長手方向Ａにおいて所定ピッチＰおきに位置しているため、バー部材７の大まかな長さを把握するための目盛の役目を果たす。これにより、溝２の実際の幅寸法Ｗが正規の寸法（設計寸法）と若干違っていても、第１凸部１５を目安にしてバー部材７の端部を切断し、バー部材７の長さを溝２の実際の幅寸法Ｗ（図３参照）に合うように微調整することが容易に行える。   Moreover, as shown in FIGS. 4 and 6, by forming the first and second convex portions 15 and 16 on the bar member 7, it is possible to prevent a person or an object passing through the upper surface of the bar member 7 from slipping. it can. Moreover, since the 1st convex part 15 is located every predetermined pitch P in the longitudinal direction A of the bar member 7, it plays the role of the scale for grasping | ascertaining the rough length of the bar member 7. FIG. Thus, even if the actual width dimension W of the groove 2 is slightly different from the normal dimension (design dimension), the end of the bar member 7 is cut using the first convex portion 15 as a guideline, and the length of the bar member 7 is increased. It is possible to easily finely adjust the height to match the actual width dimension W of the groove 2 (see FIG. 3).

尚、上記のようにしてグレーチング１を溝２に取り付けた場合、図３に示すように、バー部材７は連結部材８ａ，８ｂを介して溝２の段付部３上に支持されるため、段付部３からバー部材７の上面までは連結部材８ａ，８ｂを含んだ高さＨ１になる。   When the grating 1 is attached to the groove 2 as described above, the bar member 7 is supported on the stepped portion 3 of the groove 2 via the connecting members 8a and 8b as shown in FIG. The height from the stepped portion 3 to the upper surface of the bar member 7 is a height H1 including the connecting members 8a and 8b.

また、図１１に示すように、長手方向Ｅにおいて互いに隣接する第１の連結部材８ａのうち、一方の連結部材８ａの一方の接合部２５の接合凸部３１を他方の連結部材８ａの他方の接合部２６の接合凹部３２に挿入することにより、隣接する一方の連結部材８ａの端部と他方の連結部材８ａの端部とを接合することができる。また、上記と同様にして、長手方向Ｅにおいて互いに隣接する第１の連結部材８ａと第２の連結部材８ｂとを接合することができ、或いは、長手方向Ｅにおいて互いに隣接する第２の連結部材８ｂ同士を接合することができる。   Moreover, as shown in FIG. 11, among the first connecting members 8a adjacent to each other in the longitudinal direction E, the connecting convex portion 31 of one connecting portion 25 of one connecting member 8a is connected to the other connecting member 8a. By inserting into the joint recessed part 32 of the junction part 26, the edge part of the adjacent one connection member 8a and the edge part of the other connection member 8a can be joined. Similarly to the above, the first connecting member 8a and the second connecting member 8b adjacent to each other in the longitudinal direction E can be joined, or the second connecting members adjacent to each other in the longitudinal direction E. 8b can be joined.

（第２の実施の形態）
第２の実施の形態では、図１７に示すように、第１又は第２の連結部材８ａ，８ｂの挿入部２３をバー部材７の端部開口部１２に挿入して、複数のバー部材７を第１又は第２の連結部材８ａ，８ｂで連結することにより、グレーチング１を組み立てる。 (Second Embodiment)
In the second embodiment, as shown in FIG. 17, a plurality of bar members 7 are inserted by inserting the insertion portions 23 of the first or second connecting members 8 a and 8 b into the end openings 12 of the bar members 7. Is assembled by connecting the first and second connecting members 8a and 8b.

この際、挿入部２３をバー部材７の端部開口部１２からバー溝１１に沿って内側にスライドさせ、連結部材８ａ，８ｂを溝２の段付部３よりもさらに内側へ移動させ、バー部材７の両端部を溝２の両段付部３に設置する。   At this time, the insertion portion 23 is slid inward along the bar groove 11 from the end opening 12 of the bar member 7, and the connecting members 8 a and 8 b are moved further inward than the stepped portion 3 of the groove 2. Both end portions of the member 7 are installed on both stepped portions 3 of the groove 2.

これによると、バー部材７は、連結部材８ａ，８ｂを介さずに、直接に溝２の段付部３上に支持される。これにより、段付部３からバー部材７の上面までは連結部材８ａ，８ｂを含まない高さになるため、段付部３からバー部材７の上面までの高さＨ２を先述した第１の実施の形態における高さＨ１（図３参照）よりも低く抑えることができ、床面４から溝２の段付部３までの深さが浅い場合でも対応できる。従って、第１の実施の形態における高さＨ１（図３参照）と本第２の実施の形態における高さＨ２（図１７参照）とを使い分けることにより、床面４から溝２の段付部３までの大小２種類の深さに対応可能となる。   According to this, the bar member 7 is directly supported on the stepped portion 3 of the groove 2 without passing through the connecting members 8a and 8b. Accordingly, since the height from the stepped portion 3 to the upper surface of the bar member 7 does not include the connecting members 8a and 8b, the height H2 from the stepped portion 3 to the upper surface of the bar member 7 is the first described above. The height can be kept lower than the height H1 (see FIG. 3) in the embodiment, and even when the depth from the floor surface 4 to the stepped portion 3 of the groove 2 is shallow, it can be dealt with. Therefore, the stepped portion of the groove 2 from the floor surface 4 can be obtained by properly using the height H1 (see FIG. 3) in the first embodiment and the height H2 (see FIG. 17) in the second embodiment. 2 types of depths up to 3 can be accommodated.

（第３の実施の形態）
上記第１および第２の実施の形態では、図２に示すように、一対の第２の連結部材８ｂを円弧形状に湾曲させて溝２のカーブ部分２ｂに設置したが、第３の実施の形態では、図１８に示すように、一対の第２の連結部材８ｂを溝２の直線部分２ａの端部等に設置してもよい。この際、図１９に示すように、連結部材８ｂを長手方向Ｅにおいて伸縮させることにより、バー部材７間の間隔４１およびグレーチング１の長さを調節することができる。 (Third embodiment)
In the first and second embodiments, as shown in FIG. 2, the pair of second connecting members 8b are curved in an arc shape and installed in the curved portion 2b of the groove 2, but the third embodiment In the embodiment, as shown in FIG. 18, the pair of second connecting members 8 b may be installed at the end of the linear portion 2 a of the groove 2 or the like. At this time, as shown in FIG. 19, the distance 41 between the bar members 7 and the length of the grating 1 can be adjusted by expanding and contracting the connecting member 8 b in the longitudinal direction E.

また、図２０，図２１に示すように、５０はグレーチング１に設けられるスペーサである。図２０〜図２５に示すように、スペーサ５０は、弾力性のあるエラストマーを材質としており、隣り合うバー部材７の下端に当て付けられる本体部５１と、隣り合うバー部材７間に挿入されてバー部材７間の間隔４１を維持する間隔維持片５２（間隔維持部の一例）と、端部開口部１２からバー溝１１内に挿入可能な一対の挿入片５３，５４（挿入体の一例）と、バー部材７の浮き上がりを防止する一対の浮上り防止爪５５，５６（浮上り防止手段の一例）と、接合用突部５７（接合手段の一例）と、接合用溝部５８（接合手段の一例）とを有している。   As shown in FIGS. 20 and 21, reference numeral 50 denotes a spacer provided in the grating 1. As shown in FIGS. 20 to 25, the spacer 50 is made of elastic elastomer and is inserted between the main body portion 51 applied to the lower end of the adjacent bar member 7 and the adjacent bar member 7. An interval maintaining piece 52 (an example of an interval maintaining portion) that maintains the interval 41 between the bar members 7 and a pair of insertion pieces 53 and 54 (an example of an insert) that can be inserted into the bar groove 11 from the end opening 12. And a pair of lifting prevention claws 55 and 56 (an example of lifting prevention means) for preventing the bar member 7 from lifting, a joining protrusion 57 (an example of joining means), and a joining groove 58 (of the joining means) One example).

一対の挿入片５３，５４は本体部５１の両端部に立設され、間隔維持片５２は両挿入片５３，５４間において本体部５１に立設されている。また、浮上り防止爪５５，５６は挿入片５３，５４に設けられている。   The pair of insertion pieces 53, 54 are erected on both ends of the main body 51, and the interval maintaining piece 52 is erected on the main body 51 between the insertion pieces 53, 54. Further, the lifting prevention claws 55 and 56 are provided on the insertion pieces 53 and 54.

接合用突部５７は、台形状に形成され、スペーサ５０の一端に上下方向にわたり設けられている。接合用溝部５８は、蟻溝状に形成され、スペーサ５０の他端に上下方向にわたり設けられている。スペーサ５０の接合用突部５７を別のスペーサ５０の接合用溝部５８に挿入することにより、図２０，図２１に示すように、複数のスペーサ５０を一直線状に接合してスペーサユニット５９を形成することができる。   The joining projection 57 is formed in a trapezoidal shape, and is provided at one end of the spacer 50 in the vertical direction. The joining groove 58 is formed in a dovetail shape and is provided at the other end of the spacer 50 in the vertical direction. A spacer unit 59 is formed by joining a plurality of spacers 50 in a straight line as shown in FIGS. 20 and 21 by inserting the joining protrusion 57 of the spacer 50 into the joining groove 58 of another spacer 50. can do.

以下、上記構成における作用を説明する。
例えば、図１８，図１９に示すように、第２の連結部材８ｂを溝２の直線部分２ａの端部に設置し、連結部材８ｂを長手方向Ｅにおいて短縮することにより、バー部材７間の間隔４１が縮小され、グレーチング１の長さを短くすることができる。このように長さを短くしたグレーチング１を溝２に取り付けた場合、連結部材８ｂは強制的に圧縮されている状態から伸長しようとする反発力によって上向きに逃げようとし、これにより、図１９の仮想線で示すように、バー部材７が浮き上がろうとする。 Hereinafter, the operation of the above configuration will be described.
For example, as shown in FIGS. 18 and 19, the second connecting member 8 b is installed at the end of the linear portion 2 a of the groove 2, and the connecting member 8 b is shortened in the longitudinal direction E. The interval 41 is reduced, and the length of the grating 1 can be shortened. When the grating 1 having a reduced length is attached to the groove 2 in this way, the connecting member 8b tries to escape upward by a repulsive force that tries to extend from the state where it is forced to be compressed, and as a result, FIG. As indicated by the phantom line, the bar member 7 is about to float up.

これに対して、図２０に示すように、複数のスペーサ５０を接合してスペーサユニット５９を形成し、バー部材７の端部から、間隔維持片５２を隣り合うバー部材７間に挿入するとともに、一対の挿入片５３，５４を端部開口部１２からバー溝１１内に挿入する。   On the other hand, as shown in FIG. 20, a plurality of spacers 50 are joined to form a spacer unit 59, and a spacing member 52 is inserted between adjacent bar members 7 from the end of the bar member 7. The pair of insertion pieces 53 and 54 are inserted into the bar groove 11 from the end opening 12.

これにより、図２０，図２１に示すように、スペーサユニット５９がグレーチング１の裏側に取り付けられ、一方の浮上り防止爪５５が隣り合う一方のバー部材７のバー段付部１３に上方から係合し、他方の浮上り防止爪５６が隣り合う他方のバー部材７のバー段付部１３に上方から係合するため、バー部材７の浮き上がりを防止することができる。   As a result, as shown in FIGS. 20 and 21, the spacer unit 59 is attached to the back side of the grating 1 and one lifting prevention claw 55 is engaged with the bar stepped portion 13 of one adjacent bar member 7 from above. In addition, since the other lifting prevention claw 56 engages with the bar stepped portion 13 of the other adjacent bar member 7 from above, the lifting of the bar member 7 can be prevented.

また、間隔維持片５２がバー部材７間に挟まれることにより、バー部材７間の間隔４１を所定の間隔に維持することができるため、バー部材７に、上方から荷重が作用した場合でも、隣り合うバー部材７間の間隔４１が変化するのを防止することができる。   Moreover, since the space | interval maintenance piece 52 is pinched | interposed between the bar members 7, since the space | interval 41 between the bar members 7 can be maintained at a predetermined space | interval, even when a load acts on the bar member 7 from upper direction, It can prevent that the space | interval 41 between the adjacent bar members 7 changes.

上記第３の実施の形態では、図１８に示すように、スペーサユニット５９を、バー部材７の長手方向Ａにおける一箇所に設けたが、バー部材７の長さに応じて複数箇所に設けてもよい。また、第２の連結部材８ｂとスペーサユニット５９とを溝２の直線部分２ａの端部に設置しているが、直線部分２ａの端部に限定されるものではなく、溝２の直線部分２ａの途中に設けてもよい。   In the third embodiment, as shown in FIG. 18, the spacer unit 59 is provided at one place in the longitudinal direction A of the bar member 7, but is provided at a plurality of places according to the length of the bar member 7. Also good. Further, the second connecting member 8b and the spacer unit 59 are installed at the end of the straight portion 2a of the groove 2, but are not limited to the end of the straight portion 2a, and the straight portion 2a of the groove 2 is not limited. You may provide in the middle.

Note that female screws are formed at both ends of the core member 78.

以下、上記構成における作用を説明する。
バー部材７の端部から、分割スペーサ片７４の間隔維持片６８を隣り合うバー部材７間に挿入するとともに、挿入片６９，７０を端部開口部１２からバー溝１１内に挿入し、さらに、端部スペーサ片７５の挿入片８１を端部開口部１２からバー溝１１内に挿入する。 Hereinafter, the operation of the above configuration will be described.
From the end of the bar member 7, the interval maintaining piece 68 of the divided spacer piece 74 is inserted between the adjacent bar members 7, and the insert pieces 69 and 70 are inserted into the bar groove 11 from the end opening 12, The insertion piece 81 of the end spacer piece 75 is inserted into the bar groove 11 from the end opening 12.

次に、貫通孔７７の位置と連通孔９の位置とが一直線上になるように合わせ、貫通孔７７と連通孔９とに芯材７８を挿通し、ねじ７９を芯材７８の両端部の雌ねじに螺合して締め込む。これにより、図２５，図２７に示すように、スペーサ６６が組み立てられてグレーチング６５の裏側に取り付けられ、間隔維持片６８がバー部材７間に挟まれることによって、バー部材７間の間隔４１を所定の間隔に維持することができるため、バー部材７に、上方から荷重が作用した場合でも、隣り合うバー部材７間の間隔が変化するのを防止することができる。   Next, the position of the through hole 77 and the position of the communication hole 9 are aligned so that the core material 78 is inserted into the through hole 77 and the communication hole 9, and screws 79 are attached to both ends of the core material 78. Screw into the female screw and tighten. Thus, as shown in FIGS. 25 and 27, the spacer 66 is assembled and attached to the back side of the grating 65, and the interval maintaining piece 68 is sandwiched between the bar members 7, thereby reducing the interval 41 between the bar members 7. Since the predetermined interval can be maintained, even when a load is applied to the bar member 7 from above, it is possible to prevent the interval between the adjacent bar members 7 from changing.

また、スペーサ６６の両端部は溝２の両段付部３上に設置されるため、上方からバー部材７に作用した荷重はスペーサ６６を介して両段付部３で受けられる。これにより、バー部材７が下方に撓むのを防止することができる。   Further, since both end portions of the spacer 66 are installed on the two stepped portions 3 of the groove 2, the load acting on the bar member 7 from above is received by the both stepped portions 3 through the spacer 66. Thereby, it can prevent that the bar member 7 bends below.

また、ねじ７９を芯材７８の両端部の雌ねじに締め込むことにより、バー部材７間の間隔４１が圧縮される方向Ｊに複数のバー部材７と間隔維持片６８とが締め付けられるため、間隔維持片６８とバー部材７の側壁部７ａとが圧接され、バー部材７間の間隔４１を確実に所定の間隔（すなわち間隔維持片６８の厚さに相当する間隔）に維持することができる。   Further, by tightening the screws 79 into the female screws at both ends of the core member 78, the plurality of bar members 7 and the interval maintaining pieces 68 are tightened in the direction J in which the interval 41 between the bar members 7 is compressed. The maintaining piece 68 and the side wall 7a of the bar member 7 are pressed against each other, and the interval 41 between the bar members 7 can be reliably maintained at a predetermined interval (that is, an interval corresponding to the thickness of the interval maintaining piece 68).

上記第４の実施の形態では、図２５に示すように、スペーサ６６を、バー部材７の長手方向Ａにおける一箇所に設けたが、バー部材７の長さに応じて複数箇所に設けてもよい。
上記各実施の形態では、図４に示すように、バー部材７の上面に滑り止め用の第１および第２凸部１５，１６を形成したが、凸部の代りに第１および第２凹部を形成してもよい。 In the fourth embodiment, as shown in FIG. 25, the spacer 66 is provided at one place in the longitudinal direction A of the bar member 7, but it may be provided at a plurality of places according to the length of the bar member 7. Good.
In each of the above embodiments, as shown in FIG. 4, the first and second convex portions 15 and 16 for preventing slip are formed on the upper surface of the bar member 7, but the first and second concave portions are used instead of the convex portions. May be formed.
