Description
本考案は、マンホ―ルのマンホ―ル躯体内周壁に設置される中間スラブの改良に関するものである。 The present invention relates to an improvement of an intermediate slab installed on the peripheral wall of the manhole body in the manhole.
従来、マンホ―ルのマンホ―ル躯体内周壁に設置される中間スラブとしては、断面L字形周縁部を有する支持板をマンホ―ル躯体内周壁に固定し、該支持板の上に中間スラブを設けたものがある（例えば、特許文献１参照。）。また、中間スラブに形成した開口に開口蓋を載置するための受枠を設けたものがある（例えば、特許文献２参照。）。 Conventionally, as an intermediate slab installed on the peripheral wall of the manhole body of the manhole, a support plate having an L-shaped peripheral edge is fixed to the peripheral wall of the manhole body, and the intermediate slab is placed on the support plate. Some are provided (for example, refer to Patent Document 1). Moreover, there exists what provided the receiving frame for mounting an opening cover in the opening formed in the intermediate | middle slab (for example, refer patent document 2).
ところで、前記公知のものでは、中間スラブを構成するのに複数個の部材を使用することでコストが高くなると共にマンホールのマンホ―ル躯体内周壁に簡単に中間スラブを設置することが困難であるという問題があった。また、後者の公知のものでは、中間スラブ上の開口蓋を載置するために設けた受枠に段差があり作業者の足が引っかかってしまい安全性に問題があった。 By the way, in the said well-known thing, cost becomes high by using a some member to comprise an intermediate slab, and it is difficult to install an intermediate slab easily in the manhole housing inner peripheral wall of a manhole. There was a problem. Further, in the latter known one, there is a step in the receiving frame provided for placing the opening lid on the intermediate slab, and there is a problem in safety because the operator's foot is caught.
本考案は、従来の技術の有するこのような問題点に鑑みてなされたものであり、その目的とするところは、マンホールのマンホ―ル躯体内周壁に中間スラブを簡単・自在に設置することができ、コストの削減にもつながると共に安全性にも優れたマンホ―ル用中間スラブを提供しようとするものである。 The present invention has been made in view of such problems of the prior art, and the object of the present invention is to easily and freely install an intermediate slab on the inner wall of the manhole housing of the manhole. It is possible to provide an intermediate slab for manholes that can reduce costs and is excellent in safety.
上記目的を達成するために、本考案におけるマンホ―ル用中間スラブは、中間スラブが本体と開口蓋とボルトアンカーとから成り、前記本体が、グレ―チングとスラブ取付部と前記開口蓋を載置するための受枠とで一体に成形されていることを特徴とするものである。 In order to achieve the above object, an intermediate slab for manholes according to the present invention comprises an intermediate slab comprising a main body, an opening lid, and a bolt anchor, and the main body carries a grating, a slab mounting portion, and the opening lid. It is integrally formed with a receiving frame for placing.
本考案のマンホ―ル用中間スラブは、中間スラブが本体と開口蓋とボルトアンカーとから成り、前記本体が、グレ―チングとスラブ取付部と前記開口蓋を載置するための受枠とで一体に成形されているので、マンホ―ルのマンホ―ル躯体内周壁に中間スラブを簡単・自在に設置することができ、コストの削減にもつながると共に作業者の安全性にも優れたものとなる。 The intermediate slab for manhole according to the present invention comprises an intermediate slab comprising a main body, an opening lid, and a bolt anchor, and the main body is integrated with a grating, a slab mounting portion, and a receiving frame for placing the opening lid. The intermediate slab can be easily and freely installed on the inner wall of the manhole body of the manhole, leading to cost reduction and excellent worker safety. .
図１及び図２は本考案の一実施例に関するものであり、図１は本考案に係るマンホ―ル用中間スラブの斜視概略図、図２はマンホ―ル躯体内周壁に中間スラブを設置した一部断面側面図である。 1 and 2 relate to an embodiment of the present invention, FIG. 1 is a schematic perspective view of an intermediate slab for manholes according to the present invention, and FIG. 2 shows an intermediate slab installed on the peripheral wall of the manhole housing. It is a partial cross section side view.
図において、１はマンホ―ル用中間スラブであり、該中間スラブ１は平面視環状円形の本体２と、本体２に形成された昇降用孔３に載置する開口蓋４と、本体２をマンホ―ル躯体内周壁Wに固定するボルトアンカー５，５, …とで構成されている。 In FIG. 1, reference numeral 1 denotes an intermediate slab for manholes. The intermediate slab 1 includes an annular circular main body 2 in plan view, an opening lid 4 placed in a lifting hole 3 formed in the main body 2, and a main body 2. It is comprised with the bolt anchors 5, 5, ... fixed to the manhole housing inner peripheral wall W.
前記本体２は例えば格子状に形成されたグレ―チング６と、該グレ―チング６の外周側面に複数箇所（例えば４箇所）設けられマンホ―ル躯体内周壁Wに前記ボルトアンカー５，５, …で固定させるスラブ取付部７，７, …と、前記開口蓋４を載置するための受枠８とで、硬質合成樹脂材により一体に成形されている。 The main body 2 has, for example, a grating 6 formed in a lattice shape, and a plurality of locations (for example, four locations) provided on the outer peripheral side surface of the grating 6, and the bolt anchors 5, 5, The slab mounting portions 7, 7,... To be fixed at... And the receiving frame 8 for placing the opening lid 4 are integrally formed of a hard synthetic resin material.
前記開口蓋４は平面視円形状で全体が格子状に硬質合成樹脂材により形成されている。 The opening lid 4 has a circular shape in plan view and is formed of a hard synthetic resin material in a lattice shape as a whole.
前記各スラブ取付部７にはマンホ―ル躯体内周壁Wに埋め込まれたボルトアンカー５，５, …で固定される複数の（例えば３個）のアンカー挿入孔９，９, …が形成されている。 A plurality of (for example, three) anchor insertion holes 9, 9,... Are fixed to the slab mounting portions 7 by bolt anchors 5, 5,. Yes.
前記受枠８は前記開口蓋４が載置された状態で本体２の上面に段差がないように断面視L字状に形成されている。 The receiving frame 8 is formed in an L shape in cross section so that there is no step on the upper surface of the main body 2 in a state where the opening lid 4 is placed.
以上の構成からなるマンホ―ル用中間スラブ１において、本体２を硬質合成樹脂材によりグレ―チング６とスラブ取付部７，７, …と受枠８とを一体に成形することでコストの削減につながり、部材数の減少で運搬，設置作業も容易にできるようになる。
マンホールの内部には複数の中間スラブ１が一定間隔に設置されているが、該中間スラブ１を設置する場所のマンホ―ル躯体内周壁Wにボルトアンカー５，５, …を打ち込み、ボルトアンカー５のねじ部分をマンホール内面に突出させるようにする。そして、本体２に形成されたスラブ取付部７のアンカー挿入孔９にパッキン１０を介して前記ボルトアンカー５のねじ部分を挿着したあと、突出してるネジ部分に固定ナット１１とを螺合させることにより本体２はマンホ―ル躯体内周壁に簡単・容易に自在に固定することができる。
In the intermediate slab 1 for manholes having the above-described configuration, the main body 2 is formed of a hard synthetic resin material with the grating 6, the slab mounting portions 7, 7,. Connection and reduction of the number of parts makes it easy to carry and install.
A plurality of intermediate slabs 1 are installed at regular intervals in the manhole. Bolt anchors 5, 5,... Are driven into the peripheral wall W in the manhole housing where the intermediate slabs 1 are installed. The threaded part of this is projected on the inner surface of the manhole. And after inserting the screw part of the said bolt anchor 5 into the anchor insertion hole 9 of the slab attachment part 7 formed in the main body 2 via the packing 10, the fixing nut 11 is screwed together with the protruding screw part. Thus, the main body 2 can be easily and easily fixed to the peripheral wall of the manhole housing.
そして、本体２がマンホ―ル躯体内周壁Wに固定された後、開口蓋４を本体２に形成された受枠８に載置させて、マンホ―ル用中間スラブ１はマンホール内に設置される。受枠８が本体２に一体成形されていることから、開口蓋４を本体２に載置しても段差はできず例えば作業者がマンホ―ル用中間スラブ１上に乗っても段差でつまずくこともなく安全に作業ができるものとなる。 After the main body 2 is fixed to the peripheral wall W of the manhole housing, the opening lid 4 is placed on the receiving frame 8 formed on the main body 2, and the manhole intermediate slab 1 is installed in the manhole. . Since the receiving frame 8 is integrally formed with the main body 2, even if the opening lid 4 is placed on the main body 2, a step cannot be formed. It is possible to work safely without any problems.
