Description

本発明は、給油所及びガス充填所等のように、危険物を取り扱う敷地の周囲に構築される組立式防火塀及びその施工方法に関する。   The present invention relates to an assembly-type fire retardant constructed around a site that handles dangerous materials, such as a gas station and a gas filling station, and a construction method thereof.

給油所及びガス充填所等のように危険部を取り扱う場所では、隣接する建築物との延焼を防止するために、車両が出入りする面を除いた外周を防火塀で囲うことが法令によって義務付けられている。この防火塀は、鉄筋コンクリート製又は不燃材のパネルを組み立てて作っている。   In places where dangerous parts are handled, such as gas stations and gas filling stations, it is required by law to surround the outer periphery of the vehicle except for the surface where vehicles enter and exit, with fire retardants in order to prevent the spread of fire with adjacent buildings. ing. This fire pit is made by assembling panels of reinforced concrete or incombustible material.

鉄筋コンクリート製の防火塀は、現場で組んだ型枠にコンクリートを打設して基礎を作り、数日してコンクリートが固まった後に型枠を外し、基礎の上に組んだ型枠にコンクリートを打設して防火塀を作り、更に数日してコンクリートが固まった後に型枠を外して構築している。このように鉄筋コンクリート製の防火塀は、現場で多くの手間と日数が掛かる不都合があり、工期が長く掛かるためにコストが嵩む問題がある。また、鉄筋コンクリート製の防火塀は、重量が重くて耐震性が弱い問題もある。   Reinforced concrete fire pits are made by placing concrete in a formwork assembled on site to create a foundation, and after a few days after the concrete has hardened, remove the formwork and place the concrete on the formwork assembled on the foundation. It is set up to make fire pits, and after a few days, the concrete is solidified and then removed from the formwork. As described above, the reinforced concrete fire retardant has the disadvantage that it takes a lot of labor and days at the site, and the construction period is long, and there is a problem that the cost is increased. In addition, reinforced concrete fire pits have a problem that they are heavy and weak in earthquake resistance.

不燃材のパネルを組み立てた防火塀では、現場で組んだ型枠にコンクリートを打設して基礎を作り、数日してコンクリートが固まった後に型枠を外し、基礎の上に立設した支柱にパネルを取り付けて構築している。このように不燃材のパネルを組み立てた防火塀では、パネルで防火塀を作っているので、防火塀の作成の工期は短くなり、コストを低減できる。そして、防火塀がパネルで構成されているので、軽量化できて耐震性が高まる。しかし、基礎は現場で組んだ型枠にコンクリートを打設して作るので、工期が長く掛かり、基礎部分のコストが嵩む問題がある。   In a fire pit with non-combustible panels assembled, concrete was cast into a formwork assembled on-site to create a foundation, and after several days the concrete solidified, the formwork was removed, and the pillars were erected on the foundation It is constructed by attaching a panel. Thus, in the fire retardant assembling the non-combustible panel, the fire retardant is made from the panel, so the construction period of the fire retardant is shortened and the cost can be reduced. And since the fire pit is comprised with the panel, it can reduce in weight and an earthquake resistance increases. However, since the foundation is made by placing concrete in a formwork assembled at the site, there is a problem that the construction period is long and the cost of the foundation portion increases.

以下図面を参照して、本発明の実施の形態を説明する。
図１は本発明の組立式防火塀を実施した給油所Ｂを示す斜視図であり、図２乃至図５は組立式防火塀Ａ及びその施工方法を示す図で、図６は組立式防火塀の断面図である。 Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing a gas filling station B in which an assembled fire retardant of the present invention is implemented. FIGS. 2 to 5 are views showing an assembled fire retardant A and its construction method. FIG. FIG.

図１に示すように、組立式防火塀Ａは、給油所Ｂの敷地Ｔの道路Ｒ側を除いた周囲に築造されている。   As shown in FIG. 1, the assembly fire retardant A is built around the site R of the gas station B except for the road R side.

図２、図３に示すように、敷地Ｔの周囲の防火塀を作る場所に、一定間隔毎に溝１、１、・・・を掘る。この溝１は、例えば間隔Ｌ１＝２００ｃｍ程度で、後述するパネルの形状によって決まる。また、溝１の形状は、例えば長さＬ２＝２００ｃｍ・幅Ｌ３＝５０ｃｍ・深さＬ４＝５０ｃｍ程度で、後述する鉄骨基礎の形状により決まる。   As shown in FIGS. 2 and 3, grooves 1, 1,... Are dug at regular intervals in a place where fire pits around the site T are made. The groove 1 is determined by the shape of the panel described later, for example, with an interval L1 = about 200 cm. Further, the shape of the groove 1 is, for example, a length L2 = 200 cm, a width L3 = 50 cm, and a depth L4 = 50 cm, and is determined by the shape of the steel foundation described later.

図４に示すように、溝１に複数本、例えば２本のアンカー２が間隔をあけて打ちこまれ、そのアンカー２に鉄骨基礎３を溶接又はボルトにより取り付ける。そして、鉄骨基礎３には複数の長孔５Ａ、鉄骨支柱４には複数の長孔５Ｂが互いの接続用（図５参照）に明けられており、また鉄骨支柱４には、後述するパネルを取り付けるボルト挿通用の孔５が複数個明けられている。   As shown in FIG. 4, a plurality of, for example, two anchors 2 are driven into the groove 1 at intervals, and a steel foundation 3 is attached to the anchor 2 by welding or bolts. A plurality of long holes 5A are opened in the steel foundation 3 and a plurality of long holes 5B are opened in the steel column 4 for connection to each other (see FIG. 5). A plurality of bolt insertion holes 5 are provided.

アンカー２は、例えば長さＬ５＝１２０ｃｍ程度で、鉄骨基礎３は、例えば長さＬ６＝１００ｃｍ程度である。また、鉄骨支柱４は、例えば長さＬ７＝２００ｃｍ程度で、後述するパネルの形状によって決まる。   The anchor 2 has a length L5 = 120 cm, for example, and the steel foundation 3 has a length L6 = 100 cm, for example. Moreover, the steel-frame support | pillar 4 is length L7 = 200cm grade, for example, and is decided by the shape of the panel mentioned later.

図６に示すように、溝１の部分に仮固定してコンクリート６を打設し、アンカー２、鉄骨基礎３を固定する。このコンクリート６の打設は、溝１に流し込むだけであるので、型枠が不用である。   As shown in FIG. 6, the concrete 6 is placed by temporarily fixing the groove 1, and the anchor 2 and the steel foundation 3 are fixed. Since the casting of the concrete 6 is merely poured into the groove 1, a formwork is unnecessary.

図７、図８に示すように、コンクリート６が固まったならば、前記長孔５Ａ、５Ｂにボルト８を挿通して鉄骨基礎３と鉄骨支柱４とをナット１０で固着し（図５参照）、そして鉄骨支柱４にパネル７を取り付ける。パネル７の鉄骨支柱４への取り付けは、鉄骨支柱４に明けられた孔５にボルト８を挿通し、このボルト８をパネル７の取り付け孔９を挿通し、ボルト８にナット１０を螺合してパネル７を鉄骨支柱４に固定する。   As shown in FIGS. 7 and 8, when the concrete 6 is hardened, the bolts 8 are inserted into the long holes 5A and 5B, and the steel foundation 3 and the steel support 4 are fixed with the nut 10 (see FIG. 5). Then, the panel 7 is attached to the steel column 4. The panel 7 is attached to the steel column 4 by inserting a bolt 8 through the hole 5 opened in the steel column 4, inserting the bolt 8 through the mounting hole 9 of the panel 7, and screwing a nut 10 into the bolt 8. The panel 7 is fixed to the steel frame support 4.

パネル７は、例えば、ガラス繊維補強セメント・ガラス繊維補強プラスチック等の不燃材で作られ、板厚が薄いので軽量である。なお、パネル７の長さＬ８＝２ｍ以下で、通常のトラックで運搬できる長さであり、幅は築造される防火塀の高さによって異なるが、幅Ｌ９＝２ｍ程度である。   The panel 7 is made of a non-combustible material such as glass fiber reinforced cement and glass fiber reinforced plastic, and is light in weight because of its thin plate thickness. The length L8 of the panel 7 is 2 m or less and can be transported by a normal truck. The width varies depending on the height of the fire pit to be built, but the width L9 is about 2 m.

なお、パネル７は鉄骨支柱４の両側に取り付けても、片側だけに取り付けてもよい。   The panel 7 may be attached to both sides of the steel column 4 or may be attached to only one side.

このようにして鉄骨支柱４に取り付けたパネル７の連接部分を、不燃性のコーキング材１１でコーキングする。そして、打設コンクリート６の上面を含めた敷地Ｔないに鉄筋Ｉを配筋して設置し、その上にコンクリート１２を打設し、敷地Ｔをコンクリート舗装して、組立式防火塀Ａが完成する。   In this way, the connecting portion of the panel 7 attached to the steel column 4 is caulked with a nonflammable caulking material 11. The rebar I is placed on the site T including the top surface of the concrete 6 to be placed, the concrete 12 is placed thereon, the site T is concrete paved, and the assembly-type fire prevention fence A is completed. To do.

このように施工された防火塀Ａは下記の通りの構成を具備している。   The fire pit A thus constructed has the following configuration.

敷地Ｔ内には複数本のアンカー２に取付けられた鉄骨基礎３がコンクリート６で配設されており、その鉄骨基礎３により鉄骨支柱４を立設して固定されている。この鉄骨支柱４は塀Ａを施工する範囲に複数本が立設されており、したがって溝１は連続して長く掘削してもよく或いは１本又は２本の鉄骨支柱４を固定して間隔をあけて掘削してもよい。   In the site T, a steel foundation 3 attached to a plurality of anchors 2 is arranged with concrete 6, and a steel column 4 is erected and fixed by the steel foundation 3. A plurality of the steel struts 4 are erected in the range where the fence A is to be constructed. Therefore, the groove 1 may be continuously excavated long, or one or two steel struts 4 may be fixed and spaced apart. You may drill and drill.

このようにして立設されている複数本の鉄骨支柱４の両側にパネル７が固着手段であるボルト８およびナット１０により取付けられている。このボルト８を挿通する取付け孔９がパネル７の適所に穿孔されている。なお、この固着手段の位置は鉄骨支柱４との関連において適宜選択できる。また必要に応じて鉄骨支柱４に図示しない挿通孔を穿孔してもよい。このようにして極めて丈夫な防火塀Ａを鉄骨支柱４に組立てることができる。   Panels 7 are attached to both sides of the plurality of steel struts 4 erected in this way by bolts 8 and nuts 10 as fixing means. Mounting holes 9 through which the bolts 8 are inserted are drilled at appropriate positions on the panel 7. Note that the position of the fixing means can be selected as appropriate in relation to the steel column 4. Further, an insertion hole (not shown) may be drilled in the steel column 4 as necessary. In this way, the extremely strong fire retardant A can be assembled to the steel column 4.

危険部を取り扱う場所の外周を囲う防火塀の耐震性が高められ、築造コストを低減することができる。   The earthquake resistance of the fire pit surrounding the outer periphery of the place where the dangerous part is handled can be improved, and the construction cost can be reduced.
