Description
【0001】[0001]
本考案は、主として鉄骨造りの新築建物を構築する際に好適に使用される床穿 孔用型枠材に関するものである。 The present invention mainly relates to a floor perforating frame material which is preferably used when constructing a new steel frame building.
【0002】[0002]
前記のような建物を構築する際の建築工事に当たっては、電気、瓦斯、水道及 び通気換気等に関する種々の設備工事に関連して、コンクリート打設時に床に対 して貫通部分を形成する必要がある。床穿孔用型枠材は、この貫通部分の形成に 使用される。 In constructing the building as described above, it is necessary to form a penetration part to the floor at the time of placing concrete, in connection with various facility works related to electricity, gas, water supply, ventilation ventilation, etc. There is. Forming material for perforating the floor is used to form this penetration.
【0003】 従来のこの種の床穿孔用型枠材としては、紙管が一般に使用されている。すな わち、従来工法においては、例えば図12に示すように、デッキプレートaの所 定位置に紙管bを配置し、この状態でデッキプレートaにコンクリートcを打設 し、このコンクリートcが硬化した後に紙管bを除去して貫通部分Sが形成され るようにしている。紙管bは、貫通部分Sへのコンクリートcの侵入を防止する ために下端とデッキプレートaとの間に空隙を生じないことが要求される。A paper tube is generally used as a conventional form material for perforating floors of this type. That is, in the conventional method, as shown in FIG. 12, for example, a paper tube b is arranged at a predetermined position of the deck plate a, and in this state concrete c is placed on the deck plate a, and the concrete c After the paper is cured, the paper tube b is removed so that the penetrating portion S is formed. The paper tube b is required to have no gap between the lower end and the deck plate a in order to prevent the concrete c from entering the penetrating portion S.
【0004】[0004]
従来の床穿孔用型枠材にあっては、床穿孔用型枠材を配置する作業が繁雑であ るという不具合があった。すなわち、デッキプレートは、強度を向上させるため に底板部と頂板部との間を一定角度に傾いた斜板部で連結した凹凸形状をなして いることが通例であるが、凹凸の位置は現場の状況によって決定されるため設計 段階では定められていない。一方、前記所定位置は種々の配線、配管等の要求に より設計段階で定められている。このため、床穿孔用型枠材の下端とデッキプレ ートの空隙を解消するには、前記所定位置におけるデッキプレートの凹凸形状に 対応して床穿孔用型枠材の下端を現場で加工する必要があった。 The conventional form material for perforating floors has a problem that the work of placing the form material for perforating floors is complicated. That is, in order to improve strength, the deck plate usually has an uneven shape in which the bottom plate and the top plate are connected by a swash plate that is inclined at a certain angle, but the position of the unevenness is different on the site. It is not determined at the design stage because it is determined by the situation of. On the other hand, the predetermined position is determined in the design stage according to the requirements of various wirings, pipes, and the like. Therefore, in order to eliminate the gap between the bottom edge of the floor drilling formwork and the deck plate, it is necessary to machine the bottom edge of the floor drilling formwork on site to correspond to the uneven shape of the deck plate at the predetermined position. was there.
【0005】 また、床穿孔用型枠材が紙管であるとコンクリートの打設後に除去しなければ ならないという問題点があった。すなわち、床穿孔用型枠材は現場で下端を加工 可能とする必要上から紙管であることが望ましいが、紙管は可燃であるので防火 上の必要からコンクリートの硬化後に必ず除去しなければならなかった。 また、床穿孔用型枠材が紙管であると固定が不十分となりやすいという問題点 があった。すなわち、紙管をコンクリートの硬化後に除去しやすくするために、 デッキパネルに対する固定は粘着テープやモルタル等を介して予め除去しやすく 行うことが通例であり、コンクリートの打設作業において例えばホースによる打 撃等により外れやすかった。Further, if the form material for perforating the floor is a paper tube, there has been a problem that it must be removed after the concrete is poured. That is, it is desirable that the form material for perforating the floor is a paper tube because it is necessary to be able to process the lower end on site, but since the paper tube is flammable, it must be removed after hardening of the concrete because it is necessary for fire protection. did not become. In addition, if the form material for perforating the floor is a paper tube, there is a problem that fixing is likely to be insufficient. That is, in order to make it easy to remove the paper tube after the concrete has hardened, it is customary to fix it to the deck panel beforehand with adhesive tape, mortar, etc. It was easy to come off by a shot.

以下、本考案の一実施例を、図1〜図6を参照して説明する。 本考案を適用した床穿孔用型枠材2は、図1に示すように、デッキプレート1 に載設して、コンクリート6の打設の際に貫通部分Sを形成するために用いられ るものである。 An embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, a floor perforating formwork 2 to which the present invention is applied is used to mount a deck plate 1 and to form a through portion S when pouring concrete 6. Is.
【0012】 デッキプレート1は、断面凹凸形状をなして圧延された鋼板であって、段差D を有する底板部1aと頂板部1bとが所定角度Aで傾いた斜板部1cを介して結 合されている。 床穿孔用型枠材2は、鋼板製であって、図2及び図3に示すように、略直方体 の本体3と、この本体3の側壁31に固定する第一補助板4及び第二補助板5と を具備するものである。なお、この床穿孔用型枠材2は、プラスチック製として もよい。The deck plate 1 is a rolled steel plate having an uneven cross-section, and a bottom plate portion 1 a having a step D 1 and a top plate portion 1 b are joined via a swash plate portion 1 c inclined at a predetermined angle A.

And a plate 5. The floor perforating mold material 2 may be made of plastic.
【0013】 本体3は、板金を折曲加工したもので、四面の側壁31からなる上下に開放し た方形パイプ形状をなすものである。各側壁31には、複数のボルト係合孔32 を同一高さに一定間隔をおいて穿設する。また、デッキプレート1の下端3aで は、凹凸方向と平行となる2つの側壁31から延出部33を内側方へ水平に延出 させ、この延出部33には複数のボルト挿通孔を穿設しておく。この本体3は、 2つの延出部33の内側端とデッキプレート1の延長方向と平行となる2つの側 壁31とで平面視略正方形をなすように構成する。The main body 3 is formed by bending a sheet metal, and has a rectangular pipe shape which is composed of four side walls 31 and which is opened vertically. A plurality of bolt engaging holes 32 1 are formed in each side wall 31 at the same height at regular intervals. In addition, at the lower end 3a of the deck plate 1, an extending portion 33 is horizontally extended inward from two side walls 31 that are parallel to the uneven direction, and a plurality of bolt insertion holes are formed in the extending portion 33. Set up. The main body 3 is configured such that the inner ends of the two extending portions 33 and the two side walls 31 that are parallel to the extending direction of the deck plate 1 form a substantially square shape in a plan view.
【0014】 第一補助板4は、水平幅をデッキプレート1の頂板部1b間の間隔と略同一と し、上下幅をデッキプレート1の段差Dより十分大きくしたもので、水平方向に 延びるボルト挿通溝41を穿設するとともに、下辺4aの二隅を所定角度Aで斜 めに切り欠いて斜辺4bを形成する。切り欠かれた後の下辺4a及び斜辺4bの 長さは、デッキプレート1の底板部1a及び斜板部1cの幅とそれぞれ略同一と する。また、下辺4aからは、延出部42を外側方へ水平に延出させ、この延出 部42には例えば2つのボルト挿通孔を穿設しておく。The first auxiliary plate 4 has a horizontal width substantially equal to the space between the top plate portions 1b of the deck plate 1 and a vertical width sufficiently larger than the step D of the deck plate 1, and is a bolt extending in the horizontal direction. The insertion groove 41 is bored, and two corners of the lower side 4a are obliquely cut at a predetermined angle A to form a slanted side 4b. The lengths of the lower side 4a and the oblique side 4b after being cut out are substantially the same as the widths of the bottom plate portion 1a and the swash plate portion 1c of the deck plate 1, respectively. Further, the extending portion 42 is horizontally extended outward from the lower side 4a, and the extending portion 42 is provided with, for example, two bolt insertion holes.
【0015】 第二補助板5は、デッキプレート1の延長方向と平行となる側壁31と略同形 のもので、上下方向に延びる複数のボルト挿通溝51をボルト係合孔32と対応 させて穿設する。また、下辺5aからは、延出部52を外側方へ水平に延出させ 、この延出部52には例えば2つのボルト挿通孔を穿設しておく。 この床穿孔用型枠材2を鉄骨造りの建物を構築する際の建築工事に使用する方 法を図4〜図6に基づいて説明する。図4に示すように、予めデッキプレート1 の上方に鉄筋11が配置された状態で、設計時に貫通部分Sの位置と定められた デッキプレート1の所定位置に、本体3の側壁31の一つが直立しつつデッキプ レート1の延長方向に平行となるように床穿孔用型枠材2を載設する。この際、 前記所定位置のデッキプレート1の凹凸形状によって、本体3の下端3aにはデ ッキプレート1に添接しない部分が生じる。本実施例では、デッキプレート1の 延長方向と平行な1つの側壁31とデッキプレート1の凹凸方向と平行な2つの 側壁31の一部が頂板部1bに添設しているのみである。このため、デッキプレ ート1の凹凸方向と平行となる2つの側壁31には、該側壁31直下の底板部1 a及び該底板部1aに隣接する2つの斜板部1cにそれぞれ下辺4a及び2つの 斜辺4bが添接可能な位置で、2枚の第一補助板4をボルト挿通溝41に挿通し たボルトをボルト係合孔32に螺着することにより固定する。また、頂板部1b に添接しないデッキプレート1の延長方向と平行な側壁31には、該側壁31直 下のデッキプレート1の底板部1aもしくは斜板部1cに下辺5aが添接可能な 位置で、第二補助板5をボルト挿通溝51に挿通したボルトをボルト係合孔32 に螺着することにより固定する。次いで、図5に示すように、延出部33、42 、52のボルト挿通孔に挿通したタッピングビス21を介して床穿孔用型枠材2 をデッキプレート1に固定し、本体3の上端に蓋22を蓋着したのち、デッキプ レート1にコンクリート6を打設する。この蓋22は、本体3内にコンクリート 6が侵入するのを防止するだけでなく、本体3を補強する役割をも担うものであ る。コンクリート6が硬化した後、蓋22を除去すれば床穿孔用型枠材2の内空 間が貫通部分Sを形成するので、図6に示すように、貫通部分S内に露出したデ ッキプレート1に瓦斯バーナー等により配管孔7を穿設し、ここに必要な配管8 を配設する。配管8は、貫通部分Sに注入するモルタル9により固定する。なお 、貫通部分Sの形状は、従来の紙管を用いた場合と異なり平面視略方形であって 、特に隅部と円柱パイプ形状の配管8との間に十分な量のモルタル9を注入する ことができる。また、この床穿孔用型枠材2は金属製であり不燃なので、コンク リート6の打設後にも取り外す必要はない。The second auxiliary plate 5 has substantially the same shape as the side wall 31 parallel to the extension direction of the deck plate 1, and has a plurality of vertically extending bolt insertion grooves 51 corresponding to the bolt engagement holes 32. Set up. Further, an extension portion 52 is horizontally extended outward from the lower side 5a, and for example, two bolt insertion holes are formed in the extension portion 52. A method of using the floor-piercing formwork 2 for construction work when constructing a steel frame building will be described with reference to FIGS. 4 to 6. As shown in FIG. 4, in a state where the reinforcing bars 11 are arranged above the deck plate 1 in advance, one of the side walls 31 of the main body 3 is placed at a predetermined position of the deck plate 1 which is determined as the position of the penetrating portion S at the time of design. The form material 2 for floor perforation is placed so as to be upright and parallel to the extension direction of the deck plate 1. At this time, due to the concavo-convex shape of the deck plate 1 at the predetermined position, the lower end 3a of the main body 3 has a portion which is not attached to the deck plate 1. In this embodiment, only one side wall 31 parallel to the extension direction of the deck plate 1 and two side walls 31 parallel to the uneven direction of the deck plate 1 are attached to the top plate portion 1b. Therefore, the two side walls 31 that are parallel to the uneven direction of the deck plate 1 have lower sides 4a and 2 respectively on the bottom plate portion 1a immediately below the side wall 31 and the two swash plate portions 1c adjacent to the bottom plate portion 1a. The two first auxiliary plates 4 are fixed by screwing the bolts inserted into the bolt insertion grooves 41 into the bolt engagement holes 32 at the positions where the two oblique sides 4b can be attached. Further, on the side wall 31 parallel to the extension direction of the deck plate 1 not abutting on the top plate portion 1b, a position where the lower side 5a can be abutted on the bottom plate portion 1a or the swash plate portion 1c of the deck plate 1 immediately below the side wall 31. Then, the second auxiliary plate 5 is fixed by screwing the bolt inserted in the bolt insertion groove 51 into the bolt engagement hole 32. Then, as shown in FIG. 5, the floor drilling formwork 2 is fixed to the deck plate 1 via the tapping screws 21 inserted into the bolt insertion holes of the extending portions 33, 42 and 52, and is fixed to the upper end of the main body 3. After the lid 22 is attached, concrete 6 is placed on the deck plate 1. The lid 22 not only prevents the concrete 6 from entering the main body 3 but also serves to reinforce the main body 3. After the concrete 6 is hardened, if the lid 22 is removed, the inner space of the form material 2 for perforating the floor forms the penetrating portion S, so that the deck plate 1 exposed in the penetrating portion S is formed as shown in FIG. A pipe hole 7 is bored by a gas burner or the like, and the necessary pipe 8 is arranged therein. The pipe 8 is fixed by a mortar 9 injected into the penetrating portion S. It should be noted that the shape of the penetrating portion S is substantially rectangular in plan view unlike the case where a conventional paper tube is used, and in particular, a sufficient amount of mortar 9 is injected between the corner and the pipe 8 having a cylindrical pipe shape. be able to. Further, since the frame material 2 for perforating the floor is made of metal and is incombustible, it is not necessary to remove it even after the concrete 6 is placed.
【0016】 なお、本体3は平面視略正方形に限定されるものではなく、例えば、図7に示 すように、デッキプレート1の凹凸方向に延長されて複数の頂板部1bを股がる ものでもよく、図8に示すように、デッキプレート1の延長方向に延長されたも のでもよい。 また、他の実施例として、本体3が平面視略正方形であるときには、図9に示 すように、第一補助板4を、水平幅が本体3の水平幅と略同一とし、上下幅がデ ッキプレート1の底板部1aと頂板部1bとの段差Dより十分大きいものとして 、第二補助板5として第一補助板4を上下反転させたものを使用可能とするよう 構成したものが挙げられる。The main body 3 is not limited to a substantially square shape in a plan view, and for example, as shown in FIG. 7, the main body 3 extends in the uneven direction of the deck plate 1 and has a plurality of top plate portions 1b. Alternatively, as shown in FIG. 8, it may be extended in the extension direction of the deck plate 1. As another embodiment, when the main body 3 has a substantially square shape in a plan view, as shown in FIG. 9, the first auxiliary plate 4 has a horizontal width substantially the same as the horizontal width of the main body 3 and a vertical width. An example of the deck plate 1 which is sufficiently larger than the step D between the bottom plate portion 1a and the top plate portion 1b is a second auxiliary plate 5 which is configured so that a vertically inverted first auxiliary plate 4 can be used. .
【0017】 また、他の実施例として、図10に示すように、第一補助板4を、水平幅をデ ッキプレート1の凹凸方向と平行な本体の水平幅と略同一とし、上下幅をデッキ プレート1の延長方向と平行な本体3の水平幅と略同一として、第二補助板5と して斜辺4bを形成していない側辺を下にした第一補助板4を使用可能とするよ う構成したものが挙げられる。As another embodiment, as shown in FIG. 10, the first auxiliary plate 4 has a horizontal width substantially the same as the horizontal width of the main body parallel to the concave-convex direction of the deck plate 1 and the vertical width of the deck. With the horizontal width of the main body 3 parallel to the extension direction of the plate 1 being substantially the same, it is possible to use, as the second auxiliary plate 5, the first auxiliary plate 4 with the side not forming the oblique side 4b facing down. The ones that have been configured are listed.
【0018】 また、他の実施例として、図11に示すように、所定角度Aで斜めに切り欠い た斜辺10aを具備する台形状の第三補助板10を第一補助板4の代替としてデ ッキプレート1の凹凸方向と平行な側壁31に固定したものが挙げられる。この 第三補助板10は、デッキプレート1の延長方向と平行であってデッキプレート 1の頂板部1bに添設しない本体3の側壁31が斜板部1cの直上にあるときに 好適に使用できる。すなわち、第1補助板4は、本体3の頂板部1aから斜板部 1cの直上にのりだす部分が小さいと側壁31に添設する部分が小さくなって固 定しにくくなるが、第三補助板10では上下に固定位置をずらして対応すること ができ、かつ第一補助板4より小さくできるので取り扱いも容易である。As another embodiment, as shown in FIG. 11, a trapezoidal third auxiliary plate 10 having oblique sides 10a obliquely cut at a predetermined angle A is used as a substitute for the first auxiliary plate 4. One fixed to the side wall 31 parallel to the uneven direction of the kick plate 1 may be mentioned. The third auxiliary plate 10 can be suitably used when the side wall 31 of the main body 3 which is parallel to the extension direction of the deck plate 1 and is not attached to the top plate portion 1b of the deck plate 1 is directly above the swash plate portion 1c. . That is, if the portion of the first auxiliary plate 4 protruding from the top plate portion 1a of the main body 3 directly above the swash plate portion 1c is small, the portion attached to the side wall 31 becomes small and it becomes difficult to fix it. The plate 10 can be accommodated by shifting the fixed position up and down and can be made smaller than the first auxiliary plate 4, so that it is easy to handle.
【0019】 なお、本考案の構成は以上説明したものに限定されないのは勿論である。例え ば、本考案は、本体3と第一補助板4及び第二補助板5との固定をボルトにより 行う構成に限定されるものではない。また、第一補助板4及び第二補助板5の数 は変更可能であって、側壁31に対して複数の第一補助板4及び第二補助板5を 必要に応じて固定してよい。その他、各部材の数、位置、素材及び形状等、本考 案の趣旨を逸脱しない範囲内で種々変形が可能である。Of course, the configuration of the present invention is not limited to that described above. For example, the present invention is not limited to the configuration in which the main body 3, the first auxiliary plate 4, and the second auxiliary plate 5 are fixed by bolts. Further, the numbers of the first auxiliary plate 4 and the second auxiliary plate 5 can be changed, and the plurality of first auxiliary plates 4 and the second auxiliary plates 5 may be fixed to the side wall 31 as necessary. In addition, various modifications such as the number, position, material and shape of each member can be made without departing from the spirit of the present invention.

According to the present invention, by changing the fixing positions of the first auxiliary plate and the second auxiliary plate to the side wall of the main body, the shape of the lower end of the form material for perforating the floor is adjusted to correspond to the uneven shape of the deck plate at a predetermined position. It can be changed easily.
【0021】 そして、床穿孔用型枠材を金属材料等によって製造することができるので、ボ ルト等を介して床穿孔用型枠材をデッキパネルに十分強固に固定することができ る。 さらに、床穿孔用型枠材を金属材料等の不燃性材料によって製造することがで きるので、コンクリートの硬化後に除去する必要を解消することができる。Since the form material for perforating the floor can be manufactured from a metal material or the like, the form material for perforating the floor can be firmly fixed to the deck panel via a bolt or the like. Furthermore, since the floor perforating frame material can be manufactured from a non-combustible material such as a metal material, it is possible to eliminate the need to remove the concrete after hardening.
【0022】 また、第一補助板及び第二補助板を同一部材とすることによって、必要な部品 点数を削減して作業を容易とすることができるとともに、製造コストを抑制する ことができる。 また、所定角度で斜めに切り欠いた斜辺を具備する台形状の第三補助板を前記 第一補助板の代替として使用可能とすることによって、本体の頂板部から斜板部 の直上にのりだす部分が小さくても側壁に容易に固定することができる。Further, by using the same member for the first auxiliary plate and the second auxiliary plate, it is possible to reduce the number of necessary parts, facilitate the work, and suppress the manufacturing cost. Also, by making it possible to use a trapezoidal third auxiliary plate having oblique sides cut out at a predetermined angle as an alternative to the first auxiliary plate, it is possible to protrude from the top plate part of the main body to just above the swash plate part. Even if the portion is small, it can be easily fixed to the side wall.
