図１及び図２に示すように、本実施の形態の躯体構造物１００は、床面１上に対向して配置されるとともに、互いに向き合う鋼板表面２ａを有する一対の壁パネル２と、一対の壁パネル２の鋼板表面２ａ上であって、壁パネル２の両側縁近傍で互いに対向して固定されるとともに、上方が開口している二対の受け台４と、各対の受け台４に嵌め込まれる工事機材６載置用の架台２５とを備えている。なお、図１に示すように、一対の壁パネル２は床面１の両端部に配置され、このため一対の壁パネル２により挟まれた領域が床面１とてなる。   As shown in FIG.1 and FIG.2, the frame structure 100 of this Embodiment is arrange | positioned facing the floor surface 1, and a pair of wall panel 2 which has the steel plate surface 2a which mutually faces, and a pair of On the steel plate surface 2 a of the wall panel 2, two pairs of cradles 4 that are fixed to face each other in the vicinity of both side edges of the wall panel 2 and open upward, and each pair of cradle 4 And a mount 25 for placing construction equipment 6 to be fitted. As shown in FIG. 1, the pair of wall panels 2 are disposed at both ends of the floor surface 1, and therefore, the region sandwiched between the pair of wall panels 2 is the floor surface 1.

上記構成部材のうち、架台２５は、受け台４に装着される２本の架台棒５と、２本の架台棒５の間に配置されるとともに工事機材６を載置する架台床１５とを有している。また、壁パネル２の鋼板表面２ａに設けられた一対の受け台４は、工場でのプレハブ制作段階で位置決めが行なわれ、溶接等によって壁パネル２の鋼板表面２ａ上に固定される。   Among the above components, the gantry 25 includes two gantry bars 5 to be mounted on the cradle 4 and a gantry floor 15 that is disposed between the two gantry bars 5 and on which the construction equipment 6 is placed. Have. Further, the pair of cradles 4 provided on the steel plate surface 2a of the wall panel 2 is positioned at the prefab production stage in the factory and fixed on the steel plate surface 2a of the wall panel 2 by welding or the like.

図３に示すように、壁パネル２の鋼板表面２ａに設けられた各受け台４は、鋼板表面２ａに当接する当接面１４ａと、一対の側面１４ｂと、底面１４ｃとを有し、その横断面が四角形の形状を有している。また、この受け台４に装着される架台棒５は、受け台４に嵌め込まれるよう四角柱形状を有している。   As shown in FIG. 3, each cradle 4 provided on the steel plate surface 2a of the wall panel 2 has a contact surface 14a that contacts the steel plate surface 2a, a pair of side surfaces 14b, and a bottom surface 14c. The cross section has a quadrangular shape. The pedestal bar 5 attached to the cradle 4 has a quadrangular prism shape so as to be fitted into the cradle 4.

次に、このような構成からなる本実施の形態の作用について述べる。   Next, the operation of the present embodiment having such a configuration will be described.

図１及び図２において、躯体構造物１００上に工事機材６を載置する方法について述べる。まず、上述のように、予め一対の壁パネル２の鋼板表面２ａ上であって、壁パネル２の両側縁近傍において二対の受け台４が互いに対向して固定されている。   1 and 2, a method for placing the construction equipment 6 on the frame structure 100 will be described. First, as described above, two pairs of cradles 4 are fixed to face each other in the vicinity of both side edges of the wall panel 2 on the steel plate surface 2a of the pair of wall panels 2 in advance.

次に、このように予め二対の受け台４が設けられ、鋼板表面２ａを有する一対の壁パネル２が床面１の両端部に対向して配置される。   Next, two pairs of cradles 4 are provided in advance as described above, and a pair of wall panels 2 having a steel plate surface 2 a are arranged to face both ends of the floor surface 1.

次に、床面１から離れた載置用床（図示せず）上に架台棒５と架台床１５とからなる架台２５を配置される。   Next, a gantry 25 including the gantry bar 5 and the gantry floor 15 is placed on a mounting floor (not shown) separated from the floor surface 1.

次に、載置用床の上に配置した架台２５の架台床１５上に工事機材６を載置される。その後、工事機材６を載置した架台２５の架台棒５に吊りワイヤ８を巻き掛け、架台棒５に巻き掛けた吊りワイヤ８を揚重機７によって持ち上げて操作し、架台２５の架台棒５を載置用床から一対の壁パネル２に設けられた受け台４に装着される。   Next, the construction equipment 6 is placed on the gantry floor 15 of the gantry 25 arranged on the mounting floor. Thereafter, the suspension wire 8 is wound around the gantry bar 5 of the gantry 25 on which the construction equipment 6 is placed. It is mounted on a cradle 4 provided on the pair of wall panels 2 from the mounting floor.

本実施の形態によれば、図１及び図２に示すように、一対の壁パネル２の一対の受け台４上に、工事機材６載置用の架台２５の架台棒５が嵌め込まれ、この架台２５上に機器ユニット、資材等の工事機材６を載置することができる。   According to the present embodiment, as shown in FIGS. 1 and 2, the pedestal bar 5 of the pedestal 25 for placing the construction equipment 6 is fitted on the pair of pedestals 4 of the pair of wall panels 2. Construction equipment 6 such as equipment units and materials can be placed on the gantry 25.

このため、工事機材６を躯体構造物１００内に搬入した場合でも、工事機材６を床面１に仮置きせずにすむので、仮置きした工事機材６を再度床面１から吊上げることなく、床面１を塗装することができ、また床面１上において機器の配管工事をすることができる。さらに、床面１上方に一定のスペースを確保できるので、作業者は床面１上の室内での機器配管工事などを効率よく行うことができる。   For this reason, even when the construction equipment 6 is carried into the frame structure 100, the construction equipment 6 is not temporarily placed on the floor surface 1. Therefore, the temporarily placed construction equipment 6 is not lifted from the floor surface 1 again. The floor surface 1 can be painted, and equipment piping work can be performed on the floor surface 1. Furthermore, since a certain space can be secured above the floor surface 1, the worker can efficiently perform equipment piping work in the room on the floor surface 1.

また、図１に示すように、二対の受け台４は、床面１の両端部に設けられた一対の壁パネル２の鋼板表面２ａ上であって、壁パネル２の両側縁近傍で互いに対向して固定されており、架台２５の架台棒５は、受け台４に嵌め込まれている。このため、架台棒５の間に配置される架台床１５は、床面１と同程度の面積を有することになる。このため、躯体構造物１００内での工事機材６の配置位置に合わせて、架台２５の架台床１５上に予め工事機材６を整頓して配置することができ、架台２５の架台床１５上に配置された工事機材６を再配置することなく短時間で、躯体構造物１００内に配置することできる。   As shown in FIG. 1, the two pairs of cradles 4 are on the steel plate surfaces 2 a of the pair of wall panels 2 provided at both ends of the floor surface 1, and are adjacent to each other in the vicinity of both side edges of the wall panel 2. The pedestal bar 5 of the pedestal 25 is fixed in opposition to the cradle 4. For this reason, the gantry floor 15 disposed between the gantry bars 5 has the same area as the floor surface 1. For this reason, according to the arrangement position of the construction equipment 6 in the frame structure 100, the construction equipment 6 can be arranged in advance on the gantry floor 15 of the gantry 25 and arranged on the gantry floor 15 of the gantry 25. The arranged construction equipment 6 can be arranged in the frame structure 100 in a short time without rearranging.

次に、壁パネル２の鋼板表面２ａに設けられた受け台４の変形例について述べる。   Next, a modified example of the cradle 4 provided on the steel plate surface 2a of the wall panel 2 will be described.

また、図３に示すように、受け台４は、当接面１４ａと、一対の側面１４ｂと、底面１４ｃとを有する四角形の断面形状を有しているが、受け台４の４つの面１４ａ、１４ｂ、１４ｃのうち一対の側面１４ｂと底面１４ｃとが壁パネル２の鋼板表面２ａ上に折りたたまれるように構成してもよい。この場合、工事機材６を載せた架台２５を壁パネル２の受け台４上に配置して、工事機材６を躯体構造物１００内に設置する。次に、受け台４から架台２５を取り外し、その後、受け台４の一対の側面１４ｂと底面１４ｃとを鋼板表面２ａ上に折りたたんで、壁パネル２の鋼板表面２ａ上にコンクリートを塗ることができる。このため、受け台４を壁パネル２の鋼板表面２ａから取り外す必要が無くなり、より簡単に建築物を完成させることができる。   As shown in FIG. 3, the cradle 4 has a quadrangular cross-sectional shape having a contact surface 14 a, a pair of side surfaces 14 b, and a bottom surface 14 c, but the four surfaces 14 a of the cradle 4. , 14b and 14c, a pair of side surfaces 14b and bottom surface 14c may be folded on the steel plate surface 2a of the wall panel 2. In this case, the gantry 25 on which the construction equipment 6 is placed is disposed on the cradle 4 of the wall panel 2, and the construction equipment 6 is installed in the frame structure 100. Next, the gantry 25 can be removed from the cradle 4, and then the pair of side surfaces 14 b and the bottom surface 14 c of the cradle 4 can be folded on the steel plate surface 2 a and concrete can be applied to the steel plate surface 2 a of the wall panel 2. . For this reason, it is not necessary to remove the cradle 4 from the steel plate surface 2a of the wall panel 2, and the building can be completed more easily.

また、図４（ａ）に示すように、横断面が半円形の形状を有する受け台４ａを用いるとともに、その受け台４ａに嵌め込まれるよう円柱形状を有する架台棒５ａを用いることができる。このように、受け台４の横断面を半円形とすることで、架台２５の架台床１５上に載せた工事機材６からの重みを均等に壁パネル２に伝えることができるので、より重い工事機材６を架台２５の架台床１５に載せることができる。   Moreover, as shown to Fig.4 (a), while using the base 4a which has a semicircular cross section, the base rod 5a which has a column shape so that it may be fitted in the base 4a can be used. Thus, by making the cross section of the cradle 4 semi-circular, the weight from the construction equipment 6 placed on the gantry floor 15 of the gantry 25 can be evenly transmitted to the wall panel 2, so that heavier construction work is performed. The equipment 6 can be placed on the gantry floor 15 of the gantry 25.

また、図４（ｂ）に示すように、横断面が三角形の形状を有する受け台４ｂを用いるとともに、その受け台４ｂに嵌め込まれるよう三角柱形状を有する架台棒５ｂを用いることができる。このように、受け台４ｂの横断面を三角形とすることで、壁パネル２に対する架台２５の位置をより堅固に固定することができる。   Moreover, as shown in FIG.4 (b), while using the cradle 4b whose cross section has a triangular shape, the mount rod 5b which has a triangular prism shape so that it may be fitted by the cradle 4b can be used. Thus, the position of the mount 25 with respect to the wall panel 2 can be more firmly fixed by making the cross section of the receiving stand 4b into a triangle.

なお、壁パネル２は圧力プラントの柱などの他の躯体よりも頑丈な構造をしているので、他の躯体を用いた場合よりも、重い工事機材６を架台２５の架台床１５上に載せることができる。   In addition, since the wall panel 2 has a structure stronger than other housings such as a pillar of a pressure plant, the heavy construction equipment 6 is placed on the platform floor 15 of the platform 25 as compared with the case where other housings are used. be able to.

第２の実施の形態
次に図５により本発明の第２の実施の形態について説明する。図５に示す第２の実施の形態は一対の壁パネル２の鋼板表面２ａ上であって、壁パネル２の両側縁近傍で互いに対向して固定される二対の受け台４を用いる代わりに、一対の壁パネル２の鋼板表面２ａ上であって、壁パネル２の両側縁近傍の間に延在するとともに、互いに対向して固定される一対の受け台４を用いたものである。また２本の架台棒５と、この２本の架台棒５の間に配置される工事機材６を載置する架台床１５からなる架台２５を用いる代わりに、一枚の板からなる板状の架台２５が用いられている。図５において、他は図１乃至図４に示す第１の実施の形態と略同一である。 The next Figure 5 a second embodiment will be described a second embodiment of the present invention. The second embodiment shown in FIG. 5 is on the steel plate surface 2a of the pair of wall panels 2 and instead of using two pairs of cradles 4 fixed opposite to each other in the vicinity of both side edges of the wall panel 2. The pair of cradles 4 are used on the steel plate surfaces 2a of the pair of wall panels 2 and extend between the vicinity of both side edges of the wall panel 2 and are fixed to face each other. Further, instead of using the gantry 25 composed of the gantry floor 15 on which the two gantry bars 5 and the construction equipment 6 arranged between the two gantry bars 5 are placed, a plate-shaped plate composed of one sheet is used. A gantry 25 is used. In FIG. 5, the rest is substantially the same as the first embodiment shown in FIGS.

図５に示す第２の実施の形態において、図１乃至図４に示す第１の実施の形態と同一部分には同一符号を付して詳細な説明は省略する。   In the second embodiment shown in FIG. 5, the same parts as those in the first embodiment shown in FIGS.

図５に示すように、一対の壁パネル２の一対の受け台４上に、工事機材６載置用の架台２５が嵌め込まれ、この架台２５上に機器ユニット、資材等の工事機材６を載置することができる。   As shown in FIG. 5, a mounting base 25 for placing the construction equipment 6 is fitted on the pair of receiving bases 4 of the pair of wall panels 2, and the construction equipment 6 such as equipment units and materials is placed on the mounting base 25. Can be placed.

このため、工事機材６を躯体構造物１００内に搬入した場合でも、工事機材６を床面１に仮置きせずにすむので、仮置きした工事機材６を再度床面１から吊上げることなく、床面１を塗装することができ、また床面１上において機器の配管工事をすることができる。さらに、床面１上方に一定のスペースを確保できるので、作業者は床面１上の室内での機器配管工事などを効率よく行うことができる。   For this reason, even when the construction equipment 6 is carried into the frame structure 100, the construction equipment 6 is not temporarily placed on the floor surface 1. Therefore, the temporarily placed construction equipment 6 is not lifted from the floor surface 1 again. The floor surface 1 can be painted, and equipment piping work can be performed on the floor surface 1. Furthermore, since a certain space can be secured above the floor surface 1, the worker can efficiently perform equipment piping work in the room on the floor surface 1.

また、図５に示すように、一対の受け台４は、床面１の両端部に設けられた一対の壁パネル２の鋼板表面２ａ上であって、壁パネル２の両側縁近傍の間に延在するとともに、互いに対向して固定されている。さらに、架台２５は、一対の受け台４に嵌め込まれている。このため、架台２５は、床面１と同程度の面積を有することになる。このため、躯体構造物１００内での工事機材６の配置位置に合わせて、架台２５上に予め工事機材６を整頓して配置することができ、架台２５上に配置された工事機材６を再配置することなく短時間で、躯体構造物１００内に配置することできる。   Further, as shown in FIG. 5, the pair of cradles 4 are on the steel plate surfaces 2 a of the pair of wall panels 2 provided at both ends of the floor surface 1, and between the vicinity of both side edges of the wall panel 2. It extends and is fixed opposite to each other. Further, the gantry 25 is fitted into the pair of cradle 4. For this reason, the gantry 25 has the same area as the floor surface 1. Therefore, the construction equipment 6 can be arranged in advance on the gantry 25 in accordance with the arrangement position of the construction equipment 6 in the frame structure 100, and the construction equipment 6 arranged on the gantry 25 can be re-installed. It can arrange | position in the housing structure 100 in a short time, without arrange | positioning.

図５に示すように、架台２５は一枚の板からなるので、容易かつ安価に架台２５を準備することができる。また、架台２５を嵌め込む受け台４は、広い表面積で壁パネル２に固定されているので、より重い工事機材６を架台２５上に載置することができる。   As shown in FIG. 5, since the gantry 25 is made of a single plate, the gantry 25 can be prepared easily and inexpensively. Further, since the cradle 4 into which the gantry 25 is fitted is fixed to the wall panel 2 with a large surface area, heavier construction equipment 6 can be placed on the gantry 25.
