図1は、本発明による飛散防止養生システム100の一実施例で、解体される高層ビル50の正面図である。本実施例の高層ビル50は11階で地上から屋上(RFL)までは、約45mである。図1は南側の側面であり、図1に示すように、5基の工事用エレベータ3が約10mの間隔で立設される。北面側の側面にも、同様に5基の工事用エレベータ3が立設される。工事用エレベータ3は地上から屋上に伸びるガイドレール6と、ガイドレール6に装着され昇降する昇降載置台11からなる。高層ビル50の前後左右の側面には、地上から屋上に向かって伸びる養生足場5が設けられる。養生足場の外側には、高層ビル50をすっぽりと覆うように矩形の防音パネル4が固定具で取付けられ、外部に音が漏れないようにされる。工事用エレベータ3は、防音パネル4の内側にあって、外からは見えない。 FIG. 1 is a front view of a skyscraper 50 to be demolished in an embodiment of the anti-scattering curing system 100 according to the present invention. The skyscraper 50 of this embodiment is on the 11th floor, and the distance from the ground to the roof (RFL) is about 45 m. FIG. 1 is a side surface on the south side, and as shown in FIG. 1, five construction elevators 3 are erected at intervals of about 10 m. Similarly, five construction elevators 3 will be erected on the north side. The construction elevator 3 includes a guide rail 6 extending from the ground to the rooftop, and an elevating stand 11 mounted on the guide rail 6 to move up and down. Curing scaffolds 5 extending from the ground toward the roof are provided on the front, rear, left, and right sides of the skyscraper 50. A rectangular soundproof panel 4 is attached to the outside of the curing scaffold with a fixture so as to completely cover the skyscraper 50 so that sound does not leak to the outside. The construction elevator 3 is inside the soundproof panel 4 and cannot be seen from the outside.

高層ビル50の屋上には、5本の屋根トラス2が架け渡される。屋根トラス2は鋼材からなるトラス構造で、全体が切妻状又は上部が平坦なほぼ水平な梁状で、切妻状の屋根トラス2の脚部又は梁状の屋根トラス2の両端が南北2本の工事用エレベータ3、3の昇降載置台11、11に取り付けられる。屋根トラス2は、重機7を屋上に投入するため、屋上より上側に突出する。飛散防止ネット及びシート1は、屋根トラス2に取り付けられ、前後左右の側面と上面を覆う。飛散防止ネット及びシート1は、破片や張力ボルトの外への飛散を防止し、例えば網目サイズが1〜3cmで、衝撃にも強いネットと、衝撃で破損しやすいが、ほこりや粉塵を通さず、防音や防水(雨)の効果があるシートからなる。図1に示すように、屋根トラス2の間は、水平つなぎ31と筋交17で連結される。 Five roof trusses 2 are laid on the roof of the skyscraper 50. The roof truss 2 is a truss structure made of steel, and has a gable-shaped shape or a substantially horizontal beam shape with a flat upper part. The legs of the gable-shaped roof truss 2 or both ends of the beam-shaped roof truss 2 are two north and south. It is attached to the elevating mounts 11 and 11 of the construction elevators 3 and 3. The roof truss 2 projects upward from the roof because the heavy machinery 7 is thrown into the roof. The shatterproof net and the seat 1 are attached to the roof truss 2 and cover the front, rear, left and right side surfaces and the upper surface. The shatterproof net and sheet 1 prevent debris and tension bolts from scattering to the outside.

以下、切妻状の屋根トラス2を主として図2以下で説明する
図2は、切妻状の屋根トラス2を用いた場合の図1の高層ビル50の左側面図である。一端の屋根トラス2には、複数の間柱32と、筋交17が設けられる。これにより屋根トラス2を安定化でき、また、飛散防止ネット及びシート1が風で揺れないように固定できる。
Hereinafter, the gable-shaped roof truss 2 will be mainly described with reference to FIGS. 2 and 2. FIG. 2 is a left side view of the skyscraper 50 of FIG. 1 when the gable-shaped roof truss 2 is used. The roof truss 2 at one end is provided with a plurality of studs 32 and braces 17. As a result, the roof truss 2 can be stabilized, and the shatterproof net and the sheet 1 can be fixed so as not to be shaken by the wind.

図3は梁状の屋根トラス2を用いた場合の高層ビル50の左側面図である。
ここでは、内部が分かるように、防音パネル4、飛散防止ネット及びシート1等は省略した。梁状の屋根トラス2の両端は工事用エレベータ3の3、3の昇降載置台11、11に取り付けられる。
この場合、内側で重機7が動きやすいように、切妻状の屋根トラス2の場合より、ガイドレール6は上方に延長される
FIG. 3 is a left side view of the skyscraper 50 when the beam-shaped roof truss 2 is used.
Here, the soundproof panel 4, the shatterproof net, the sheet 1, and the like are omitted so that the inside can be seen. Both ends of the beam-shaped roof truss 2 are attached to the elevating stands 11 and 11 of the construction elevators 3 and 3.
In this case, the guide rail 6 is extended upward from the case of the gable-shaped roof truss 2 so that the heavy machine 7 can move easily inside.

図4は、図1の高層ビル50の平面図である。5本の屋根トラス2が、前後方向(南北方向)に架け渡される。屋根トラス2は、クレーンで屋上に揚重され、屋上で組み立てる。屋根トラス2は、所定の長さの部材で、連結して屋根トラス5とする。クレーンで吊り上げて、切妻状の屋根トラス2の脚部又は梁状の屋根トラス2の両端が工事用エレベータ3の昇降載置台11に取り付ける。屋根トラス2は、斜めに交差する大筋交12で互いに連結される。大筋交12にはパイプが使用される。屋根トラス2に装着した飛散防止ネット及びシート1は、上面中央部に出し入れ口15(太い点線で示す)があり、カーテンのように開口可能に構成される。屋根トラス2の上端が屋上付近に来るよう工事用エレベータ3を下降させておけば、飛散防止ネット及びシート1の取付作業がしやすい。 FIG. 4 is a plan view of the skyscraper 50 of FIG. Five roof trusses 2 are bridged in the front-rear direction (north-south direction). The roof truss 2 is lifted on the roof by a crane and assembled on the roof. The roof truss 2 is a member having a predetermined length and is connected to form a roof truss 5. It is lifted by a crane, and the legs of the gable-shaped roof truss 2 or both ends of the beam-shaped roof truss 2 are attached to the elevating stand 11 of the construction elevator 3. The roof trusses 2 are connected to each other by diagonally intersecting general lines 12. A pipe is used for the main line twelve. The shatterproof net and the sheet 1 attached to the roof truss 2 have an entrance / exit 15 (indicated by a thick dotted line) at the center of the upper surface, and are configured to be openable like a curtain. If the construction elevator 3 is lowered so that the upper end of the roof truss 2 is near the rooftop, the shatterproof net and the sheet 1 can be easily attached.

図5は、図4のA部拡大図(平面図)である。図5は昇降載置台11と養生足場5との関係を示す図である。高層ビル50の外壁16の外側には、養生足場5が組み付けられる。大梁18は外壁16の内側にある。養生足場5は、筋交17が縦横に連結され、足場となるプレート19が取付けられる。養生足場5の外側に防音パネル4が取付けられる。ガイドレール6は、長尺で垂直に伸びるハシゴ形状のもので、中央にラック22が取り付けられる。ラック22は、昇降載置台11の底部に設けられた昇降用モータ21で駆動されるピニオン(図示せず、駆動歯車のこと)と噛み合う。昇降載置台11に、切妻状の屋根トラス2の脚部又は梁状の屋根トラス2の両端が固定される。昇降載置台11が上下方向に昇降するので、迅速に屋根トラス2を昇降できる。工事用エレベータ3の頂部付近は、養生足場5が左右に分断された形となる。 FIG. 5 is an enlarged view (plan view) of part A of FIG. FIG. 5 is a diagram showing the relationship between the elevating platform 11 and the curing scaffold 5. A curing scaffold 5 is assembled on the outside of the outer wall 16 of the high-rise building 50. The girder 18 is inside the outer wall 16. In the curing scaffold 5, the brace 17 is connected vertically and horizontally, and a plate 19 serving as a scaffold is attached. A soundproof panel 4 is attached to the outside of the curing scaffold 5. The guide rail 6 is long and has a ladder shape extending vertically, and a rack 22 is attached to the center. The rack 22 meshes with a pinion (not shown, a drive gear) driven by an elevating motor 21 provided at the bottom of the elevating platform 11. The legs of the gable-shaped roof truss 2 or both ends of the beam-shaped roof truss 2 are fixed to the elevating stand 11. Since the elevating platform 11 moves up and down in the vertical direction, the roof truss 2 can be quickly moved up and down. Near the top of the construction elevator 3, the curing scaffolding 5 is divided into left and right.

図6は、養生足場5と工事用エレベータ3の関係を示す図である。昇降載置台11が高層ビル50の頂部付近に移動させた後は、昇降載置台11の下側の空間は、作業員が往復するので、プレート19が取付けられ、養生足場5が左右に分断されることがない。なお、フロア解体(各階の床と壁の解体)が進み、昇降載置台11が下降してくれば、この部分のプレート19が撤去される。 FIG. 6 is a diagram showing the relationship between the curing scaffold 5 and the construction elevator 3. After the elevating platform 11 is moved to the vicinity of the top of the high-rise building 50, the space under the elevating platform 11 is reciprocated by workers, so that the plate 19 is attached and the curing scaffold 5 is divided into left and right. There is nothing to do. If the floor is dismantled (the floor and walls of each floor are dismantled) and the elevating stand 11 is lowered, the plate 19 in this portion is removed.

図7は、養生足場5の足元を示す詳細図(側面図)である。高層ビル50の外壁16の外側には、養生足場5が組み付けられる。養生足場5の外側に防音パネル4が取付けられる。養生足場5は、筋交17が自在クランプ20で固定され、足場となるプレート19が取付けられる。ハシゴ形状の長尺なガイドレール6は、垂直に立設される。 FIG. 7 is a detailed view (side view) showing the feet of the curing scaffold 5.

In the curing scaffold 5, the brace 17 is fixed by the universal clamp 20, and the plate 19 serving as the scaffold is attached. The ladder-shaped long guide rail 6 is erected vertically.

図8は、養生足場5の上部を示す詳細図(側面図)である。工事用エレベータ3の昇降載置台11に、切妻状の屋根トラス2の脚部又は梁状の屋根トラス2の両端が固定される。屋上より上の部分には、防音パネル4を設けず、養生足場5の外側を飛散防止ネット及びシート1が覆う。屋根トラス2が下降されると、飛散防止ネット及びシート1も下降することになるので、フロア解体(各階の床と壁の解体)が進行すれば、これに合わせて、養生足場5も上部側から順次撤去される。その分工期も短くできる。図8に示すように、昇降載置台11は、ガイドレール6に装着され上下方向に昇降できる。昇降載置台11の底部には、昇降用モータ21が設けられ、ピニオン(歯車)が設けられ、該ピニオンがラック22と噛み合って、昇降載置台11が昇降する。図8の右側の写真は、ガイドレール6を含めて取り出した昇降載置台11の写真である。写真では昇降載置台11の天板は外している。切妻状の屋根トラス2の脚部又は梁状の屋根トラス2の両端は、昇降載置台11に左右方向に1つの接点で連結される。 FIG. 8 is a detailed view (side view) showing the upper part of the curing scaffold 5. Both ends of the gable-shaped roof truss 2 or the beam-shaped roof truss 2 are fixed to the elevating stand 11 of the construction elevator 3. A soundproof panel 4 is not provided on the portion above the roof, and the outside of the curing scaffold 5 is covered with a shatterproof net and a sheet 1. When the roof truss 2 is lowered, the shatterproof net and the seat 1 are also lowered. Therefore, if the floor dismantling (floor and wall dismantling of each floor) progresses, the curing scaffolding 5 is also on the upper side. Will be removed sequentially from. The construction period can be shortened. As shown in FIG. 8, the elevating platform 11 is mounted on the guide rail 6 and can be moved up and down in the vertical direction. An elevating motor 21 is provided at the bottom of the elevating platform 11, and a pinion (gear) is provided. The pinion meshes with the rack 22 to elevate the elevating platform 11. The photograph on the right side of FIG. 8 is a photograph of the elevating stand 11 taken out including the guide rail 6. In the photograph, the top plate of the elevating stand 11 is removed. The legs of the gable-shaped roof truss 2 or both ends of the beam-shaped roof truss 2 are connected to the elevating stand 11 at one contact point in the left-right direction.

図9は、屋根トラス2の構成を示す説明図である。屋根トラス2は、これに限るものではないが、本実施例では、長さLが5mの部材を使用した。(a)に示すように、4本の部材を連結した場合、底辺の長さBL1を15.5mにできる。(b)に示すように、12本の部材を連結した場合、底辺の長さBL2を53.5mにできる。このように高層ビル50の幅に対応して、屋根トラス2の長さを調節できる。図には示さないが、短い寸法出しの調整部材(トラス)もある。 FIG. 9 is an explanatory view showing the configuration of the roof truss 2.
