Description

本発明は、建造物スラブ躯体より滴下する雨水や地下水等の漏水から、照明器具、火災報知器、電線、空調機、空調用ダクト等の設備や天井仕上げ材、および通行人を保護するための、建造物躯体下に設けられる天井漏水バリア構造に関する。 The present invention protects equipment such as lighting fixtures, fire alarms, electric wires, air conditioners, air conditioning ducts, ceiling finishing materials, and passers-by from leakage of rainwater and groundwater dripping from the building slab housing. The present invention relates to a ceiling water leakage barrier structure provided under a building frame.

従来、コンクリ−ト建造物において施工不良または老朽化に伴い、雨水や地下水等が、躯体スラブに発生したクラック部を通って下層階へ浸水する場合がある。図９は従来の代表的な天井工法を示すが、漏水が発生し天井に水が溜まると、天井仕上げ材のジョイントや、天井仕上げ材を留めている小ねじ周縁部から水漏れが生じる。その際、天井仕上げ材が窯業系の場合では、ボ−ド材には耐水性が殆ど無い材料が多いため、十分に水分を吸ったボ−ドが、脆くなり、ボ−ドが落下する事故が多発している。また、天井仕上げ材が金属系の場合では、その水漏れ箇所からの応急的な排水処理として、適当なビニ−ルシ−トを張って、柱又は側壁に沿って漏水を流し、天井下の通行人に、水漏れの有ることの注意を喚起する看板等を立てている。諸設備機器に関しても不具合が生じ、例えば、電気機器などを損傷させている。 Conventionally, rainwater, groundwater, etc. may infiltrate into a lower floor through a crack portion generated in a frame slab due to poor construction or aging in a concrete building. FIG. 9 shows a typical conventional ceiling construction method. When water leaks and water accumulates on the ceiling, water leaks from the joint of the ceiling finishing material and the peripheral part of the small screw holding the ceiling finishing material. At that time, when the ceiling finishing material is ceramic, there are many board materials that have almost no water resistance, so the board that has sufficiently absorbed moisture becomes brittle and the board falls. Has occurred frequently. Also, if the ceiling finish is made of metal, as an emergency drainage treatment from the location of the water leak, a suitable vinyl sheet is stretched, the water leaks along the pillar or side wall, and the passage under the ceiling Signs etc. are erected to alert people that water is leaking. Problems have also arisen with respect to various equipment, for example, electrical equipment and the like are damaged.

近年このような問題に対処するために、種々の工法が提案されている。例えば、躯体スラブ下側に防水板の端縁を梁に近接した状態で配置し、前記梁の下端縁に沿って梁用樋を設けるとともに、この梁用樋の端縁位置より下方で、柱に巻装される回り樋を設け、前記防水板から流水する漏水を前記梁用樋を介して回り樋に集水する漏水回収装置が示されている（例えば、特許文献１参照）。 In recent years, various methods have been proposed to deal with such problems. For example, the edge of the waterproof plate is arranged in the state close to the beam at the lower side of the frame slab, the beam rod is provided along the lower edge of the beam, and the column is located below the edge position of the beam rod. There is shown a leakage recovery device that is provided with a swirl wound around and that collects leaked water flowing from the waterproof plate to the swirl through the beam reed (see, for example, Patent Document 1).

また、天井仕上げ材を多数枚並設して、前記天井仕上げ材長手方向端において直交的に延在する樋兼フレ−ムを配設し、前記天井仕上げ材からの漏水を前記樋兼フレ−ムに流し集水樋に集めて排水させる天井構造が示されている（例えば、特許文献２参照）。 Further, a large number of ceiling finishing materials are juxtaposed, and a trough and frame extending orthogonally at the end of the ceiling finishing material in the longitudinal direction is disposed, and water leakage from the ceiling finishing material is caused to leak from the trough and frame. A ceiling structure is shown which is drained and collected in a water collecting basin and drained (see, for example, Patent Document 2).

さらに、既存天井面の下側に、断面略Ｕ字状で格子に組んだ樋兼用フレ−ムを配設して、前記樋兼用フレ−ムの上に防水板を被せ載置し、前記防水板からの漏水を流水させる防護設備が示されている（例えば、特許文献３参照）。
特開平６−９６８８０号公報実開昭６１−０４７３１５号公報特許第３６５３１６７号公報 Further, a heel / framing frame assembled in a lattice with a substantially U-shaped cross section is disposed below the existing ceiling surface, and a waterproof plate is placed on the glazing / framing frame, and the waterproofing is performed. A protective equipment for flowing water leaking from a board is shown (for example, see Patent Document 3).

しかしながら、前記特許文献１〜３に係わる防水設備では、機能的ならび意匠上、種々の問題の発生が予想される。 However, in the waterproof equipment according to Patent Documents 1 to 3, various problems are expected in terms of functional and design.

先ず特許文献１の場合は、梁を除く天井面のほぼ全面に防水板を配設し、防水板全体を完全に水漏れしない構造としなければならない。実際には天井面全体を一枚の防水板で覆うことは困難であるから、要所に防水板のジョイントが必要となり、この接続部位は高度な水密構造が要求されるが、何ら開示がない。次いで、一般工法での天井を吊る場合は、躯体スラブから吊りボルトを約９０ｃｍ間隔で吊設するが、何ら開示がなく、仮に一般工法と仮定すると、吊りボルトが約９０ｃｍ毎に防水板に当たり、吊りボルト周縁部からの漏水が予想される。また、一般的には、設備機器、および空調用ダクト等の設備も躯体スラブからボルトで吊っているが、何ら開示がなく防水板に対する対処が困難である。 First, in the case of Patent Document 1, a waterproof plate must be provided on almost the entire ceiling surface excluding the beam, so that the entire waterproof plate does not leak completely. In fact, it is difficult to cover the entire ceiling surface with a single waterproof plate, so a waterproof plate joint is required at an important point, and this connection part requires a high degree of watertight structure, but there is no disclosure. . Next, when suspending the ceiling in the general construction method, suspending bolts are suspended from the slab at about 90 cm intervals, but there is no disclosure, and assuming that the general construction method, the suspension bolt hits the waterproof plate every about 90 cm, Water leakage from the periphery of the suspension bolt is expected. In general, equipment such as equipment and air-conditioning ducts are also suspended from the housing slab by bolts, but there is no disclosure and it is difficult to cope with the waterproof board.

次いで、特許文献２の場合は、漏水からの照明器具保護のため防水カバ−を設置しているが、防水カバ−とクリップが交差する接面での漏水が予想される。また、電線、空調機、および空調用ダクト等の設備に対する保護は何ら開示がない。また、樋兼フレ−ムが天井仕上げ面の下に出るため意匠が限られる等の問題がある。 Next, in the case of Patent Document 2, a waterproof cover is installed to protect the lighting apparatus from water leakage, but water leakage at the contact surface where the waterproof cover and the clip intersect is expected. Further, there is no disclosure of protection for facilities such as electric wires, air conditioners, and air conditioning ducts. In addition, there is a problem that the design is limited because the heel and frame is exposed under the ceiling finish surface.

特許文献３の場合は、既存天井面の下側での天井漏水からの防護設備のため、使用用途が限られ、また、天井高が低くなり意匠的にも一般的とは言えない。 In the case of Patent Document 3, the use is limited because of the protective equipment against the ceiling water leakage under the existing ceiling surface, and the ceiling height is low, so it cannot be said that the design is general.

すなわち、漏水から照明器具、火災報知器、電線、空調機、空調用ダクト等の設備、および天井仕上げ材を保護するための、防水機能を十分に発揮出来る工法や、一般天井工法にも適用出来る防水工法は、皆無であった。 In other words, it can also be applied to construction methods that can fully exhibit waterproof functions to protect equipment such as lighting fixtures, fire alarms, electric wires, air conditioners, air conditioning ducts, and ceiling finishing materials from water leakage, and general ceiling construction methods. There was no waterproofing method.

上記課題を解決するための本発明に係わる天井漏水バリア構造は、構築物躯体スラブ下側で、水勾配に沿って段階的に多数本並設されている天井下地材に、鋼板長辺両側縁を断面逆ハット形に折曲形成され、底面を漏水受けとしたガ−ドパネルと、下方開放した断面コ字状のＴバ−下地を交互に並設して、小ねじで係止し、固定された前記Ｔバ−下地のフランジに、底部が樋機能を備えているＴバ−を嵌合することを特徴とする。
上記において、前記天井下地材を吊設してボルト孔を有するＣ形鋼下面に、下方開放した断面コ字状で折曲形成され、所定の位置にボルト孔を有する水切りを、平行方向に配置し、前記ボルト孔が複数形成された、そのボルト孔に吊りボルトを貫通立設し、前記Ｃ形鋼下部フランジの上側と前記水切り下側にナットを配し、ナットにより一体的に締着することで吊りボルトの安定した接合状態が得られる。 In order to solve the above problems, the ceiling water leakage barrier structure according to the present invention has a structure in which a large number of side edges on the long side of the steel plate are attached to a ceiling base material arranged in parallel along the water gradient on the lower side of the structure slab. A guard panel that is bent into a reverse hat shape in cross section and has a bottom receiving water leak, and a T-bar base with a U-shaped cross section that opens downward, are alternately arranged side by side and locked with a small screw. Further, a T-bar having a bottom function is fitted to the flange of the T-bar base.
In the above, a water drainer which is bent and formed in a U-shaped cross-section opened downward on a C-shaped steel lower surface having a bolt hole suspended from the ceiling base material and having a bolt hole at a predetermined position is arranged in a parallel direction. A plurality of the bolt holes are formed, and a suspension bolt is pierced through the bolt hole, and nuts are arranged on the upper side of the lower flange of the C-shaped steel and the lower side of the drainage, and are fastened integrally with the nuts. Thus, a stable joined state of the suspension bolt can be obtained.

（Ａ）本発明に係る天井漏水バリア構造によれば、建造物スラブ躯体と天井仕上げ材、および諸設備器具等との間にバリアパネル等で防水層を作り、建造物スラブ躯体より滴下する漏水から、天井仕上げ材、および諸設備器具等を守る工法である。防水層はバリアパネルと、Ｔバ−および水切りで構成されており、バリアパネル等の部材は、構造が簡単で、小型で、軽量で、取り扱いが容易なため、施工性に優れていて、各防水板同士の接続係止は小ねじで締結される工法ではあるが、小ねじ孔から水漏れする従来技術と異なり、漏水が小ねじ孔の周縁部から水漏れしても、導水装置を有しているので、防水板接続部からの水漏れが一切生じない工法であり、また、既存天井および、重量物である諸設備機材等も十分な取付強度で吊ることが出来る工法である。 (A) According to the ceiling water leakage barrier structure according to the present invention, a water leakage layer is formed by forming a waterproof layer with a barrier panel or the like between the building slab housing, the ceiling finishing material, and various equipment, and dropping from the building slab housing. Therefore, it is a method of protecting ceiling finishing materials and various equipment. The waterproof layer is composed of a barrier panel, a T-bar, and a drainer. The members such as the barrier panel are simple in structure, small in size, lightweight, and easy to handle. The connection locking between the waterproof plates is a method that is fastened with a small screw, but unlike the conventional technology where water leaks from the small screw hole, even if the water leaks from the peripheral part of the small screw hole, the water guiding device is provided. Therefore, it is a construction method that does not cause any water leakage from the waterproof plate connecting portion, and it is a construction method that can suspend the existing ceiling and various heavy equipments with sufficient mounting strength.

First, the guard panel 1 is a long steel plate member having an inverted cross-sectional hat shape, which receives water leakage at the bottom surface 1a, and has a structure in which the flange 1b is attached to the light grooved steel 8 as a base material with a small screw 4. is there. The guard panel 1 has a width of about 20 to 40 cm, a length of about 4 to 6 m, a height of about 2.5 cm, and a plate thickness of about 0.8 mm. If the weight can be constructed, and the weight is important, the thickness of the guard panel 1 is not particularly limited as long as a rib is attached to the bottom surface 1a of the guard panel 1 and sufficient strength can be secured. The material of the guard panel 1 is preferably a metal material such as a hot dip galvanized steel plate, a hot 55% aluminum-zinc alloy plated steel plate and stainless steel, but is not particularly limited.

以下、図面に基づいて本発明に係る天井漏水バリア構造の二つの実施形態例を説明する。 Hereinafter, two exemplary embodiments of a ceiling water leakage barrier structure according to the present invention will be described with reference to the drawings.

（本発明に係る天井下地組第１の実施例）
本発明の実施形態を添付図面に基づき詳細に説明する。図３に示すように、図中符号１はガ−ドパネル、２ａはＴバ−、２ｂはＴバ−下地、３は水切り、８は軽ミゾ形鋼、９はＣ形鋼、１０は吊りＡボルト、１１は吊りＢボルトをそれぞれ示している。 (First embodiment of the ceiling foundation set according to the present invention)

As shown in FIG. 3, reference numeral 1 is a guard panel, 2a is a T-bar, 2b is a T-bar base, 3 is drained, 8 is a light grooved steel, 9 is a C-shaped steel, 10 is a suspended A Bolts 11 are suspension B bolts.

本発明に係る天井漏水バリア構造は、構築物躯体スラブ（図示せず）から吊り下げられた吊りＡボルト１０に、Ｃ形鋼９を固定し、前記Ｃ形鋼９の下面に水切り３を当接し、その水切り３の下側に前記水切りと交差した軽ミゾ形鋼８を配設し、本発明に係るガ−ドパネル１およびＴバ−２ａを、前記軽ミゾ形鋼８に取り付けるとともに、吊りＢボルト１１を前記Ｃ形鋼９に前記水切り３を絡まし取り付け、防水層を形成するものである。 In the ceiling water leakage barrier structure according to the present invention, a C-shaped steel 9 is fixed to a suspended A bolt 10 suspended from a structure slab (not shown), and a drainer 3 is brought into contact with the lower surface of the C-shaped steel 9. A light grooved steel 8 intersecting the draining is disposed below the drainer 3, and the guard panel 1 and the T bar-2a according to the present invention are attached to the light grooved steel 8 and suspended B Bolts 11 are attached to the C-shaped steel 9 by entwining the drainer 3 to form a waterproof layer.

以下、詳細にその構造について施工手順を交えながら詳述する。
先ず、図４に示すように、構築物躯体スラブ１３から所定の位置に吊り下げられた吊りＡボルト１０を、Ｃ形鋼９上部フランジに形成されているボルト貫通孔に挿入し、前記Ｃ形鋼９上部フランジの上側と下側にナット６を配し、水勾配に合わせ前記Ｃ形鋼９の一方を傾斜させて、水勾配の調整を行い前記各ナット６で締着し、前記Ｃ形鋼９を固定する。次いで、前記Ｃ形鋼９の下側に水切り３とアングルピ−ス７を配し、前記Ｃ形鋼９下部フランジに有するボルト孔と、前記水切り３に有するボルト孔と、前記アングルピ−ス７に有するボルト孔とを重ね、その複数形成されたボルト孔にボルト５を挿入立設し、ナット６で締着して、前記Ｃ形鋼９と、前記水切り３、および前記アングルピ−ス７の前記３体を、一体化する。その後、前記Ｃ形鋼９の下側に付着されている、前記アングルピ−ス７垂直のフランジ面と、前記軽ミゾ形鋼８の背面を合わせ、前記アングルピ−ス７と前記軽ミゾ形鋼８のボルト孔に、ボルト５を水平に挿入し、ナット６で締着し、前記軽ミゾ形鋼８を固定する。 Hereinafter, the structure will be described in detail with the construction procedure.
First, as shown in FIG. 4, the suspended A bolt 10 suspended from the structure slab 13 at a predetermined position is inserted into a bolt through-hole formed in the upper flange of the C-shaped steel 9, and the C-shaped steel. 9 Nuts 6 are arranged on the upper and lower sides of the upper flange, one of the C-shaped steels 9 is inclined according to the water gradient, the water gradient is adjusted, and the nuts 6 are fastened to each other. 9 is fixed. Next, a drainer 3 and an angle piece 7 are arranged below the C-shaped steel 9, and a bolt hole provided in the lower flange of the C-shaped steel 9, a bolt hole provided in the drainage 3, and the angle piece 7 are provided. The bolts 5 are stacked, bolts 5 are inserted and installed in the plurality of bolt holes, fastened with nuts 6, the C-shaped steel 9, the drainer 3, and the angle pieces 7. Three bodies are integrated. Thereafter, the angle piece 7 and the light groove 8 are attached to the lower side of the C-shaped steel 9 and the vertical surface of the angle piece 7 is aligned with the back surface of the light groove 8. Bolts 5 are inserted horizontally into the bolt holes and fastened with nuts 6 to fix the light groove steel 8.

次いで、図５に示すように、前述要領によって固定された前記Ｃ形鋼９の下側に水切り３を当接し、前記Ｃ形鋼９の下部フランジに有するボルト孔と、前記水切り３に有するボルト孔とを重ねて、その複数形成されたボルト孔に、下から吊りＢボルト１１を立てながら挿入し、ナット６を前記Ｃ形鋼９下部フランジ上側と前記水切り３下面に配し、前記各ナット６で締着し、前記吊りＢボルト１１を立吊した状態で、固定する。 Next, as shown in FIG. 5, a drainer 3 is brought into contact with the lower side of the C-shaped steel 9 fixed as described above, and a bolt hole provided in a lower flange of the C-shaped steel 9 and a bolt provided in the drained 3. The holes are overlapped, and the suspended B bolts 11 are inserted into the plurality of bolt holes while standing, and the nuts 6 are arranged on the upper side of the lower flange of the C-shaped steel 9 and the lower surface of the drainer 3. Fasten with 6 and fix the suspension B bolt 11 in a suspended state.

前述までの要領によって、天井下地組みが完成されている前記軽ミゾ形鋼８に、ガ−ドパネル１と、Ｔバ−２ｂを係止するには、以下のようして行う。先ず、図５に示すように、ガ−ドパネル１を、吊りＢボルト１１の両サイドに配し、前記吊りＢボルト１１周縁と、前記ガ−ドパネル１のフランジ１ａ端縁に１０ｍｍ前後の隙間をとり、前記軽ミゾ形鋼８に、前記ガ−ドパネル１のフランジ１ｂに小ねじ４で係止する。なお、前記吊りＢボルト１１周縁と、前記ガ−ドパネル１のフランジ１ａ端縁に１０ｍｍ前後隙間をあけるのは、地震等の振動で前記吊りＢボルト１１が振れて、前記ガ−ドパネル１に当たりそのガ−ドパネル１が破損するのを回避するためである。
次に、図３に示すように、所定の間隔で配置されている、前記Ｃ形鋼９の各列中間部の下側に、ガ−ドパネル１を配し、両隣に、Ｔバ−２ａが入るような隙間をあけ、小ねじ４で係止する。 In order to lock the guard panel 1 and the T bar-2b to the light grooved steel 8 in which the ceiling foundation assembly has been completed in the manner described above, the following is performed. First, as shown in FIG. 5, the guard panel 1 is arranged on both sides of the suspension B bolt 11, and a clearance of about 10 mm is formed between the periphery of the suspension B bolt 11 and the flange 1 a edge of the guard panel 1. Then, the light groove 8 is locked to the flange 1 b of the guard panel 1 with a machine screw 4. Note that a clearance of about 10 mm is formed between the periphery of the suspension B bolt 11 and the edge of the flange 1a of the guard panel 1 because the suspension B bolt 11 is swung by vibration such as an earthquake and hits the guard panel 1.

First, as shown in FIG. 7, the upper flange is fixed to a predetermined position of the structure slab 13 with a hole-in anchor 12, and the lower flange is formed on the lower side of the C-shaped steel 9 having a bolt hole. A bolt formed by arranging an angle piece 7 and overlapping the bolt hole provided in the lower flange of the C-shaped steel 9, the bolt hole provided in the drainer 3, and the bolt hole provided in the angle piece 7. Bolts 5 are inserted upright in the holes and fastened with nuts 6 so that the C-shaped steel 9, the drainer 3, and the three pieces of the angle piece 7 are integrated. In that case, prior to the placement of the angle piece 7, a water gradient is determined in advance with a level ink, and an angle piece 7 having an elliptical bolt hole whose height can be adjusted along the water gradient is selected and prepared. To do. After that, the vertical flange surface of the angle piece 7 attached to the lower side of the C-shaped steel 9 and the back surface of the light groove shaped steel 8 are aligned to adjust the water gradient, and the angle piece is adjusted. The bolt 5 is inserted horizontally into the bolt holes of the light groove 8 and the light groove 8 and fastened with a nut 6 to fix the light groove 8.
