Description

本発明は、道路側部に沿って、又は道路を横断して埋設設置されたU字溝の改修方法に関する。   The present invention relates to a method for repairing a U-shaped groove embedded and installed along a road side or across a road.

埋設設置されたU字溝は、設置直後でもガタツキによる騒音の問題に悩ませられたり、年月が経過するに従って老朽化し、強度が低下していたり、地上に露出している部分や蓋受部が磨り減ったり欠けたりするので、このような騒音を発するU字溝や老朽化したU字溝の蓋受部を補修する必要がある。また、従来のU字溝の蓋は、厚さが100mm程度あり、その重さは45kg程度であった。したがって、蓋はかなり重く、側溝内の清掃作業をする場合などにおいて、蓋を着脱する作業が困難を極める。そこで、このような既存の蓋を騒音防止型や厚さの薄い軽量の蓋に交換したいという要望もある。   The U-shaped groove installed under the ground suffers from noise problems due to rattling, becomes obsolete over time, decreases in strength, or is exposed to the ground or lid receiving part Therefore, it is necessary to repair the U-groove that generates such noise and the lid receiving portion of the old U-groove. The conventional U-shaped groove cover has a thickness of about 100 mm and a weight of about 45 kg. Therefore, the lid is quite heavy, and it is extremely difficult to attach and detach the lid when cleaning the inside of the side groove. Therefore, there is also a demand to replace such an existing lid with a noise prevention type or a thin lightweight lid.

下記特許文献1には、既存の蓋と交換するための軽量な薄い蓋が開示されている。図14は、従来の、老朽化した側溝に軽量蓋を装着して改修する方法を説明する、蓋受部付近の断面図である。地中に埋設された既存のU字溝の既存蓋(図示せず)を取り除き、蓋受部(蓋受面1a及び縦壁1bからなる)の欠けた部分を補修する。符号21はこのような補修部で、モルタルなどの適宜の補修材を塗り、コテ仕上げをしたものである。その後、従来の蓋よりも薄く軽量な蓋20を装着する。蓋20は、レジンコンクリート製など、曲げ強度が大きいもので、下面の両側に脚部20a(角パイプなど)が設けられている。
また、蓋受部を補修する際に、蓋受面1aを、モルタルなどで脚部20aの高さまで嵩上げし、脚部を有しない蓋を装着する方法もある。
また、U字溝の蓋受部付近、例えば図14の線Xよりも上の部分をカッターで切断して取り除き、現場で、型枠を組み、コンクリートを流し込んで、取り除いた部分を作り直し、新たな蓋を装着する方法もある。
登録実用新案公報第3108053号
Patent Document 1 below discloses a lightweight thin lid for replacing an existing lid. FIG. 14 is a cross-sectional view in the vicinity of a lid receiving portion for explaining a conventional method of refurbishing a light-weight lid attached to an aged side groove. The existing lid (not shown) of the existing U-shaped groove embedded in the ground is removed, and the missing portion of the lid receiving portion (consisting of the lid receiving surface 1a and the vertical wall 1b) is repaired. Reference numeral 21 denotes such a repair portion, which is obtained by applying an appropriate repair material such as mortar and finishing with a trowel. Thereafter, the lid 20 that is thinner and lighter than the conventional lid is attached. The lid 20 is made of resin concrete and has high bending strength, and leg portions 20a (such as square pipes) are provided on both sides of the lower surface.
Further, when repairing the lid receiving portion, there is a method in which the lid receiving surface 1a is raised to the height of the leg portion 20a with mortar or the like and a lid having no leg portion is attached.
Also, remove the U-groove near the lid receiving part, for example, the part above line X in FIG. 14 by cutting with a cutter, assemble a formwork, pour concrete into the site, recreate the removed part, There is also a method to attach a simple lid.
Registered Utility Model Publication No. 3108053

上記の、蓋受部を補修した後に、脚部20aの付いた蓋を装着する方法は、補修作業が面倒な上、補修部が乾燥して強度を発現するまで蓋を装着することができないので相当の工期を要し、また、脚部20aの付いた蓋を特別に製作しなければならないという問題がある。
上記の、蓋受面1aを、モルタルなどで脚部20aの高さまで嵩上げする方法は、モルタルなどで嵩上げする作業が面倒な上、当該部分が乾燥して強度が発現するまで蓋を装着することができないので相当の工期を要するという問題がある。
上記の、U字溝の蓋受部付近を取り除き、作り直す方法は、作り直す作業がさらに面倒な上、作り直した部分が乾燥して強度が発現するまで蓋を装着することができないのでかなりの工期を要し、またコンクリート廃棄物が発生するという問題がある。
上記いずれの手法で既存の側溝形状を復元しても、蓋のガタツキによる側溝と蓋の破壊は改善されず、同等の改修工事を繰り返している現状がある。
また、上記いずれの方法も、老朽化したU字溝の強度を改善することはできない。すなわち、U字溝の近くを車両が通行した際など、U字溝には土圧と共に車輛の積載荷重が作用し、U字溝の側壁が内側に傾き、これが繰り返されることで側壁が破壊されるおそれがある。
The above-described method of attaching the lid with the leg portion 20a after repairing the lid receiving portion is troublesome in the repair work and cannot be attached until the repair portion is dried and develops strength. There is a problem that a considerable work period is required and a lid with a leg portion 20a must be specially manufactured.
The above-described method of raising the lid receiving surface 1a to the height of the leg 20a with mortar or the like is troublesome to raise the height with the mortar or the like, and attaches the lid until the portion is dried and develops strength. However, there is a problem that it takes a considerable work period.
The above-mentioned method of removing the U-groove cover receiving part and recreating it requires a considerable work period because the reworking process is more troublesome and the reworked part is dry and the cover cannot be mounted until strength is developed. In addition, there is a problem that concrete waste is generated.
Even if the shape of the existing side groove is restored by any of the above methods, the destruction of the side groove and the cover due to rattling of the lid is not improved, and there is a situation in which equivalent repair work is repeated.
In addition, none of the above methods can improve the strength of the aging U-shaped groove. That is, when a vehicle passes near the U-shaped groove, the load of the vehicle acts on the U-shaped groove together with earth pressure, and the side wall of the U-shaped groove is tilted inward, and this is repeated, thereby destroying the side wall. There is a risk.

本発明は、既存U字溝の蓋受部分の補修を省略し、従って、補修時に発生するコンクリート廃棄物がなく、容易に新たな軽量蓋を装着でき、現場での工期も短縮できるようにすることを課題とするものである。
また本発明は、老朽化したU字溝の強度を改善できるようにすることも課題とするものである。
The present invention eliminates the repair of the lid receiving portion of the existing U-shaped groove, so that there is no concrete waste generated at the time of repair, a new lightweight lid can be easily attached, and the construction period on site can be shortened. This is a problem.
Another object of the present invention is to improve the strength of an aged U-shaped groove.

本発明は、既存U字溝の既存蓋に代えて新たな蓋を装着するU字溝の改修方法であって、前記新たな蓋が、フレーム状の一次蓋と、該一次蓋の開口部に脱着自在の二次蓋からなり、既存U字溝の上部を切除することなく、前記一次蓋が前記既存U字溝の既存蓋受部に装着され、接着一体化されることを特徴とするU字溝の改修方法である。 The present invention is a method for repairing a U-shaped groove in which a new lid is mounted instead of the existing lid of an existing U-shaped groove, and the new lid is formed in a frame-shaped primary lid and an opening of the primary lid. Ri Do from detachable secondary lid, without ablating the top of an existing U-shaped grooves, the primary lid is attached to the existing lid receiving portion of the existing U-shaped grooves, characterized by Rukoto bonded and integrated This is a method of repairing the U-shaped groove.

また本発明は、既存U字溝の上部を切除することなく、所定間隔を隔てて平行に対向する2本の蓋受部材を、幅方向の連結部材を仮留めすることで仮に一体化した結合蓋受部材を、既存U字溝の既存蓋受部に装着し、該蓋受部と前記結合蓋受部材を接着一体化した後、前記連結部材を取り外し、前記2本の蓋受部材に既存蓋よりも薄い新たな蓋を装着することを特徴とするU字溝の改修方法である。 In addition, the present invention is a combination in which two lid receiving members facing each other in parallel at a predetermined interval are temporarily integrated without temporarily cutting an upper portion of an existing U-shaped groove by temporarily fastening a connecting member in the width direction. existing lid receiving member, attached to the existing lid receiving section of the existing U-shaped grooves, after bonding integrated with the lid receiving the coupling cap receiving member, detaching the coupling member, to the two cover receiving member A method for repairing a U-shaped groove, characterized in that a new lid thinner than the lid is attached.

本発明は、既存の蓋よりも薄い蓋を使用するので、蓋が軽量化され、側溝内の清掃作業をする場合などにおいて、蓋を着脱する作業が容易となる。
既存U字溝の蓋受部の補修が必要ないので、現場での作業が容易となり、コンクリート廃棄物も無くし工期も短縮できる。
一次蓋の連結部材が横梁として作用するので、既存U字溝の強度が改善され、既存U字溝の側壁が内側に傾くのを防止できる。
二次蓋として、騒音の発生しない蓋を用いることが容易にでき、車両が蓋の上を通過した際の蓋鳴りを防ぐことが可能となる。
蓋受部材に垂下壁を設けると、U字溝の蓋受面の角が欠けていても、せき板を設けることなく接着剤の注入を容易に行うことができる。
Since the present invention uses a lid that is thinner than the existing lid, the lid is reduced in weight, and the operation of attaching and detaching the lid is facilitated when cleaning the inside of the side groove.
Since there is no need to repair the existing U-shaped groove lid receiving part, the work at the site becomes easy, the concrete waste is eliminated, and the construction period can be shortened.
Since the connecting member of the primary lid acts as a cross beam, the strength of the existing U-shaped groove is improved, and the side wall of the existing U-shaped groove can be prevented from tilting inward.
As the secondary lid, it is possible to easily use a lid that does not generate noise, and it is possible to prevent the lid from ringing when the vehicle passes over the lid.
When the hanging wall is provided on the lid receiving member, even if the corner of the lid receiving surface of the U-shaped groove is missing, it is possible to easily inject the adhesive without providing a skirting plate.

本発明において、二次蓋は、既存の蓋よりも厚さが薄く、軽量のものを用いることが望ましい。   In the present invention, it is desirable to use a secondary lid that is thinner and lighter than existing lids.

本発明において、一次蓋は、既存U字溝の蓋受部に接着一体化する。接着剤としては、モルタル、セメントミルクなどの無機系接着剤、エポキシ樹脂などの樹脂系接着剤など、任意の接着剤を使用できる。一次蓋と既存U字溝の蓋受部を接着一体化することで、既存U字溝が強化される。すなわち、U字溝の側壁に土圧・積載荷重が作用したとき、一次蓋の連結部材が横梁として土圧・積載荷重に対抗し、U字溝の側壁が内側に傾くのを防止する。接着剤は、一次蓋を装着する前にU字溝の蓋受部に塗布してもよいし、一次蓋を装着した後に注入してもよい。
In the present invention, the primary lid, bonded and integrated to the lid receiving section of the existing U-shaped grooves. As the adhesive, any adhesive such as inorganic adhesives such as mortar and cement milk, and resin adhesives such as epoxy resins can be used. By bonding and integrating the primary lid and the lid receiving portion of the existing U-shaped groove, the existing U-shaped groove is strengthened. That is, when earth pressure / loading load acts on the side wall of the U-shaped groove, the connecting member of the primary lid acts as a transverse beam to counteract earth pressure / loading load and prevent the side wall of the U-shaped groove from inclining inward. The adhesive may be applied to the lid receiving part of the U-shaped groove before mounting the primary lid, or may be injected after mounting the primary lid.

本発明において、一次蓋を、所定間隔を隔てて平行に対向する2本の蓋受部材と、該2本の蓋受部材を連結する幅方向の連結部材とからなり、全体がコンクリートで一体に成形されているものとすることができる。この場合、一次蓋の蓋受部材の二次蓋と接する部分を曲面等の騒音防止型形状とし、騒音の発生しない二次蓋を用いることが容易にできる。   In the present invention, the primary lid is composed of two lid receiving members facing each other in parallel at a predetermined interval, and a connecting member in the width direction connecting the two lid receiving members, and the whole is integrally made of concrete. It can be molded. In this case, it is possible to easily use a secondary lid that does not generate noise by making a portion of the lid receiving member of the primary lid contacting the secondary lid into a noise prevention shape such as a curved surface.

また、一次蓋を、所定間隔を隔てて平行に対向する2本の蓋受部材と、該2本の蓋受部材を連結する幅方向の連結部材とからなり、全体が金属で一体に成形されているものとすることもできる。一次蓋を金属製とすることで、軽量化でき、現場での作業がより容易になる。   The primary lid includes two lid receiving members facing each other in parallel at a predetermined interval and a connecting member in the width direction for connecting the two lid receiving members, and the whole is integrally formed of metal. It can also be assumed. When the primary lid is made of metal, the weight can be reduced, and the work at the site becomes easier.

本発明において、蓋受部材に、その蓋受面の内側から下方に形成した垂下壁を設けることができる。これにより、U字溝の蓋受面の角が欠けていても、せき板を設けることなく接着剤の注入を容易に行うことができる。   In the present invention, the lid receiving member can be provided with a hanging wall formed downward from the inside of the lid receiving surface. Thereby, even if the corner | angular of the lid | cover receiving surface of a U-shaped groove | channel is missing, injection | pouring of an adhesive agent can be performed easily, without providing a skirting board.

以下、実施例を説明する図面に基づいて、本発明を詳細に説明する。図1はコンクリート製の一次蓋2及び二次蓋5の例を示す斜視図、図2は、図1の一次蓋2を既存U字溝1に装着した断面図、図3は一次蓋2を既存U字溝1に装着した平面図、図4は一次蓋2を既存U字溝1に装着した要部断面図、図5は図1の二次蓋5の斜視図、図6は二次蓋5の断面図、図7は二次蓋5の装着部分の詳細説明図、図8、9はコンクリート一次蓋の他例を示す平面図、図10は金属製一次蓋2及び結合蓋受部材12の例を示す斜視図、図11は図10の一次蓋2を既存U字溝1に装着した断面図、図12は金属製一次蓋2を既存U字溝1に装着した要部断面図、図13はコンクリート製一次蓋の他例の要部断面図である。   Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments. 1 is a perspective view showing an example of a primary lid 2 and a secondary lid 5 made of concrete, FIG. 2 is a cross-sectional view of the primary lid 2 of FIG. 1 attached to an existing U-shaped groove 1, and FIG. FIG. 4 is a cross-sectional view of the main part of the primary lid 2 attached to the existing U-shaped groove 1, FIG. 5 is a perspective view of the secondary lid 5 of FIG. 1, and FIG. 7 is a cross-sectional view of the lid 5, FIG. 7 is a detailed explanatory view of a mounting portion of the secondary lid 5, FIGS. 8 and 9 are plan views showing other examples of the concrete primary lid, and FIG. 10 is a metal primary lid 2 and a coupling lid receiving member. FIG. 11 is a cross-sectional view in which the primary lid 2 of FIG. 10 is mounted in the existing U-shaped groove 1, and FIG. 12 is a cross-sectional view of the main part in which the metal primary lid 2 is mounted in the existing U-shaped groove 1. FIG. 13 is a cross-sectional view of a main part of another example of the primary cover made of concrete.

図1〜4、7に示す一次蓋2は、コンクリートで全体が一体成形されており、所定間隔を隔てて平行に対向する2本の蓋受部材3と、その2本の蓋受部材3を連結する幅方向の連結部材4とからなり、全体が四辺形状をなし、中央部分が2枚の二次蓋5を装着する開口部となっている。既存のU字溝1の既存蓋を取り外し、その蓋受部を清掃した後、図2、3に示されるように、一次蓋を連続して既存のU字溝1の蓋受部に装着する。一次蓋2の開口部には、図1〜7に示す二次蓋5が着脱自在に装着される。二次蓋5はレジンコンクリート製又は繊維補強コンクリート製とすることが望ましいが、ダクタイル鋳鉄製や鋼製グレーチング等にすることもできる。レジンコンクリートは曲げ強度、引張強度を有するので、必要強度を得るのに蓋の厚さを薄くすることができる。さらにレジンコンクリートは可使時間の制御が可能であり、早期に高強度を発現し、接着性、水密性、耐凍結融解性、耐薬品性、耐摩耗性、電気絶縁性等に優れる。繊維補強コンクリートは、ガラス繊維、鋼繊維、カーボン繊維などの繊維をコンクリート中に分散させたものである。繊維補強コンクリートも曲げ強度、引張強度を有するので、蓋の厚さを薄くすることができる。このようにすることで、二次蓋5の厚さ、重量共に既存の蓋の1/2〜1/3程度とすることができる。したがって、U字溝の清掃作業時などにおける蓋の着脱作業を容易にすることが可能となる。二次蓋5には、雨水の流入のため、また蓋を取り外すときの手掛とするため、多数のスリット6が形成されている。   The primary lid 2 shown in FIGS. 1 to 4 and 7 is made of concrete and integrally formed, and includes two lid receiving members 3 facing each other in parallel at a predetermined interval, and the two lid receiving members 3. It consists of a connecting member 4 in the width direction to be connected, the whole is a quadrilateral shape, and the central part is an opening for mounting two secondary lids 5. After removing the existing lid of the existing U-shaped groove 1 and cleaning the lid receiving portion, the primary lid is continuously attached to the lid receiving portion of the existing U-shaped groove 1 as shown in FIGS. . A secondary lid 5 shown in FIGS. 1 to 7 is detachably attached to the opening of the primary lid 2. The secondary lid 5 is preferably made of resin concrete or fiber reinforced concrete, but may be made of ductile cast iron or steel grating. Since resin concrete has bending strength and tensile strength, the lid thickness can be reduced to obtain the required strength. In addition, the resin concrete can control the pot life, exhibits high strength at an early stage, and is excellent in adhesion, water tightness, freeze-thaw resistance, chemical resistance, wear resistance, electrical insulation, and the like. Fiber reinforced concrete is obtained by dispersing fibers such as glass fiber, steel fiber, and carbon fiber in concrete. Since the fiber reinforced concrete also has bending strength and tensile strength, the thickness of the lid can be reduced. By doing in this way, the thickness and the weight of the secondary lid 5 can be reduced to about 1/2 to 1/3 of the existing lid. Therefore, it is possible to facilitate the attaching / detaching operation of the lid at the time of cleaning the U-shaped groove. The secondary lid 5 is formed with a large number of slits 6 for inflow of rainwater and as a clue when removing the lid.

図7に、一次蓋の蓋受部材3の蓋受面と、二次蓋5の関係を示す。蓋受部材3の蓋受面3a及び二次蓋5の接面部8はいずれも曲面となっており、蓋受面3aの曲率中心O1と二次蓋の接面部8の曲率中心O2とが僅かに(0.1〜0.5mm)離れている。二次蓋5の接面部8の曲面は、O1(蓋受部材3の蓋受面3aの曲率中心)を基準として垂線から角度αの所から始まり角度βにわたって形成されている。αは、二次蓋に跳ね上がりを防止する突起部10を設けた関係上設けたもので、30°〜35°程度が適当である。突起部を設けない場合は0°でもよい。α+βは60°が適当である。接面部8の上端部は接合点9(二次蓋を装着したとき蓋受面3aと接する部分)となっており、その上部は蓋受部材3に干渉しないように、接合点9でやや折れ曲がった後直線となっている。蓋受面3aは、積載荷重がかかったときに、蓋の接面部8となるべく広い面積で接するように設計すればよい。図7に示すように、O2はO1のやや外側上方にずらすのがよい。また、蓋受面3a及び接面部8の曲率半径を11〜25mmにすると、二次蓋の上に積載荷重が作用したときの曲げ強度が大きくなり、好ましい。なお、図7ではO1とO2の距離、及び蓋受部材と二次蓋の曲面の離れ具合を強調して表している。   FIG. 7 shows the relationship between the lid receiving surface of the lid receiving member 3 of the primary lid and the secondary lid 5. The lid receiving surface 3a of the lid receiving member 3 and the contact surface portion 8 of the secondary lid 5 are both curved, and the curvature center O1 of the lid receiving surface 3a and the curvature center O2 of the contact surface portion 8 of the secondary lid are slight. (0.1 to 0.5 mm) apart. The curved surface of the contact surface portion 8 of the secondary lid 5 is formed from the perpendicular to the angle α with respect to O1 (center of curvature of the lid receiving surface 3a of the lid receiving member 3) over the angle β. α is provided for the purpose of providing a protrusion 10 for preventing the secondary lid from jumping up, and about 30 ° to 35 ° is appropriate. When no projection is provided, it may be 0 °. α + β is suitably 60 °. The upper end portion of the contact surface portion 8 is a junction point 9 (a portion that comes into contact with the lid receiving surface 3a when the secondary lid is attached), and the upper portion thereof is slightly bent at the junction point 9 so as not to interfere with the lid receiving member 3. After a straight line. The lid receiving surface 3a may be designed so as to come into contact with the contact surface portion 8 of the lid with as large an area as possible when a load is applied. As shown in FIG. 7, it is preferable to shift O2 slightly outward and upward of O1. Moreover, when the curvature radius of the lid | cover receiving surface 3a and the contact surface part 8 shall be 11-25 mm, the bending strength when a load load acts on a secondary lid becomes large, and it is preferable. In FIG. 7, the distance between O1 and O2 and the distance between the curved surface of the lid receiving member and the secondary lid are emphasized.

図7に示すのは二次蓋を一次蓋に装着した(積載荷重のない)状態で、蓋受部材3と二次蓋5とは、接面部8の端部の接合点9で接する線状の接触である。これに積載荷重が作用すると、二次蓋が僅かに変形し、蓋受面3aと接面部8とが面接触となり、接触面積が広くなって、二次蓋に作用した力が有効に一次蓋に伝達される。   FIG. 7 shows a linear shape in which the secondary lid is attached to the primary lid (no load), and the lid receiving member 3 and the secondary lid 5 are in contact with each other at the junction 9 at the end of the contact surface portion 8. Contact. When a load is applied to this, the secondary lid is slightly deformed, the lid receiving surface 3a and the contact surface portion 8 are brought into surface contact, the contact area is widened, and the force acting on the secondary lid is effectively applied to the primary lid. Is transmitted to.

二次蓋5は、一次蓋に装着した(積載荷重のない)状態では線接触で、蓋の上を車両が通行した際、蓋鳴りすることがない無騒音蓋である。   The secondary lid 5 is a noiseless lid that is in line contact when mounted on the primary lid (no load) and does not ring when the vehicle passes over the lid.

U字溝1の蓋受部と一次蓋2の間には、図4に示すように、接着剤13が充填される。この場合は、矢印Aに示す隙間から接着剤を注入している。同図に示すように、U字溝の蓋受面の角が欠けているような場合は、必要に応じて、せき板14を用いて接着剤が漏れないようにする。せき板14は、接着剤、コンクリート釘などでU字溝側壁内面に仮固定するか、突っ張り棒やターンバックルを対向する側壁内面の間に架け渡して仮固定するなど、周知の方法で仮固定され、注入作業終了後に取り外される。   As shown in FIG. 4, an adhesive 13 is filled between the lid receiving portion of the U-shaped groove 1 and the primary lid 2. In this case, the adhesive is injected from the gap indicated by the arrow A. As shown in the figure, when the corners of the U-groove lid receiving surface are missing, the slat plate 14 is used as necessary to prevent the adhesive from leaking. Temporarily fixing the dam plate 14 using a known method such as temporarily fixing the U-shaped groove side wall with an adhesive, concrete nails or the like, or suspending a tension rod or turnbuckle between the opposing side wall inner surfaces. And removed after completion of the injection operation.

一次蓋2の形状は四辺形状とは限らない。図8の一次蓋2は、全体がコンクリート製で、2本の平行する蓋受部材3の中間部を2本の連結部材4で連結している。中央の開口部に2枚の二次蓋が、両側の開口部にそれぞれ1枚の二次蓋が装着されるものである。   The shape of the primary lid 2 is not necessarily a quadrilateral shape. The primary lid 2 in FIG. 8 is entirely made of concrete, and the intermediate portions of two parallel lid receiving members 3 are connected by two connecting members 4. Two secondary lids are attached to the central opening, and one secondary lid is attached to each of the openings on both sides.

図9の一次蓋2は、全体がコンクリート製で、2本の平行する蓋受部材3の中央部を1本の連結部材4で連結している。両側の開口部にそれぞれ1枚の二次蓋が装着されるものである。   The primary lid 2 in FIG. 9 is entirely made of concrete, and the central portions of two parallel lid receiving members 3 are connected by one connecting member 4. One secondary lid is attached to each of the openings on both sides.

図10に示すのは、金属製の一次蓋2の例である。同図の一次蓋2は、鋼板を加工して製造されたもので、所定間隔を隔てて平行に対向する2本の蓋受部材3と、その2本の蓋受部材3を連結する幅方向の連結部材4とからなり、全体が四辺形状をなし、中央部分が2枚の二次蓋5を装着する開口部となっている。蓋受部材3には、蓋受面3aが形成され、その下面に、高さ調整のための台足部11が各2個所形成されている。また、蓋受面3aの内側には、垂下壁7が垂下形成されている。既存のU字溝1の既存蓋を取り外し、その蓋受部を清掃した後、図11に示されるように、一次蓋を連続して既存のU字溝1の蓋受部に装着する。一次蓋を装着すると、台足部11がU字溝1の蓋受面の上に載置される。一次蓋2の開口部には、図11、12に示されるように、既存の蓋の1/2〜1/3程度の厚さの二次蓋5が着脱自在に装着される。二次蓋5はレジンコンクリート製又は繊維補強コンクリート製とすることが望ましいが、ダクタイル鋳鉄製や鋼製グレーチング等にする事もできる。この場合は、蓋受面3aが平面に形成され、二次蓋5の接面部も平面となっているが、前記実施例に示されるような蓋受面3aを曲面などの騒音防止型構造とし、無騒音蓋を使用することも可能である。   FIG. 10 shows an example of a metal primary lid 2. The primary lid 2 shown in the figure is manufactured by processing a steel plate, and two lid receiving members 3 facing each other in parallel at a predetermined interval, and a width direction connecting the two lid receiving members 3. The connecting member 4 is formed in a quadrilateral shape, and the central portion is an opening for mounting two secondary lids 5. A lid receiving surface 3a is formed on the lid receiving member 3, and two foot portions 11 for height adjustment are formed on the lower surface thereof. Further, a hanging wall 7 is formed on the inner side of the lid receiving surface 3a. After removing the existing lid of the existing U-shaped groove 1 and cleaning the lid receiving portion, the primary lid is continuously mounted on the lid receiving portion of the existing U-shaped groove 1 as shown in FIG. When the primary lid is mounted, the foot portion 11 is placed on the lid receiving surface of the U-shaped groove 1. As shown in FIGS. 11 and 12, the secondary lid 5 having a thickness of about 1/2 to 1/3 of the existing lid is detachably attached to the opening of the primary lid 2. The secondary lid 5 is preferably made of resin concrete or fiber reinforced concrete, but may be made of ductile cast iron or steel grating. In this case, the cover receiving surface 3a is formed in a flat surface, and the contact surface portion of the secondary cover 5 is also a flat surface. However, the cover receiving surface 3a as shown in the above embodiment has a noise prevention type structure such as a curved surface. It is also possible to use a noiseless lid.

U字溝1の蓋受部と一次蓋2の間には、図12に示すように、接着剤13が充填される。この場合は、矢印Aに示す隙間から接着剤を注入している。一次蓋2には垂下壁7が形成されているので、U字溝の蓋受面の角が欠けているような場合でも、図4に示すようなせき板を用いる必要がない。   As shown in FIG. 12, an adhesive 13 is filled between the lid receiving portion of the U-shaped groove 1 and the primary lid 2. In this case, the adhesive is injected from the gap indicated by the arrow A. Since the drooping wall 7 is formed in the primary lid 2, even if the corner of the lid receiving surface of the U-shaped groove is missing, it is not necessary to use a dam plate as shown in FIG.

図10において、連結部材4を両側の蓋受部材3に仮留めすると、本願発明の結合蓋受部材12となる。仮留めは、適当な間隔の点溶接、ボルト留めなど、容易に取り外すことができる留め方である。その場合は、結合蓋受部材12をU字溝の蓋受部に装着し、接着剤で固定した後、連結部材4を取り外し、その後二次蓋を両側の蓋受部材に支持させて装着する。二次蓋を装着した状態は、図12に示されている場合と同じになる(連結部材4がない点のみ異なる)。連結部材4は、蓋受部材を所定の間隔を保ってU字溝の蓋受部に装着するための定規として作用する。   In FIG. 10, when the connecting member 4 is temporarily fastened to the lid receiving members 3 on both sides, a combined lid receiving member 12 of the present invention is obtained. Temporary fastening is a fastening method that can be easily removed, such as spot welding or bolting at an appropriate interval. In that case, after attaching the coupling lid receiving member 12 to the lid receiving portion of the U-shaped groove and fixing with the adhesive, the connecting member 4 is removed, and then the secondary lid is supported by the lid receiving members on both sides and attached. . The state in which the secondary lid is attached is the same as that shown in FIG. 12 (the only difference is that there is no connecting member 4). The connecting member 4 acts as a ruler for attaching the lid receiving member to the U-groove lid receiving portion at a predetermined interval.

垂下壁7は、コンクリート製の一次蓋に設けることも可能である。図13はその例で、コンクリート製の一次蓋の蓋受部材3の蓋受面3aの内側から垂下壁7を垂下形成している。これにより、U字溝の蓋受面の角が欠けているような場合でも、図4に示すようなせき板を用いる必要がなくなる。   The hanging wall 7 can also be provided on a primary cover made of concrete. FIG. 13 shows an example in which a hanging wall 7 is suspended from the inner side of the lid receiving surface 3a of the lid receiving member 3 of the concrete primary lid. Thereby, even when the corner of the lid receiving surface of the U-shaped groove is missing, it is not necessary to use a dam plate as shown in FIG.

本発明において、二次蓋の材質はコンクリート製に限らず、金属製(例えば鋼板、鋳鉄製)、木製、プラスチック製やこれらの組み合わせなど、種々の材質を用いることができる。二次蓋として無騒音蓋を用いる場合、実施例に示したタイプのものに限らず、種々の周知のタイプのものを用いることもできる。また、二次蓋としてグレーチングを採用することもできる。1つの一次蓋に装着する二次蓋の数は自由であり、所望の枚数を装着するように自由に設計することができる。   In the present invention, the material of the secondary lid is not limited to concrete, and various materials such as metal (for example, steel plate, cast iron), wood, plastic, and combinations thereof can be used. When a noiseless lid is used as the secondary lid, not only the types shown in the embodiments but also various known types can be used. Moreover, grating can also be employ | adopted as a secondary cover. The number of secondary lids attached to one primary lid is arbitrary, and can be freely designed to attach a desired number of lids.
