Abstract

PROBLEM TO BE SOLVED: To shorten the time required for the construction of a fireproof coating of a fireproof building with a narrow gap between the column member of a corner part and an exterior wall.SOLUTION: A sheet-like fireproof coating material 14 is wound around column members 1 erected at positions to be four corners of a mechanical multistory parking lot which is a fireproof building. Then, an external wall is constructed with a panel 4 locked through a hook to a furring strip member 2 attached to the column member 1 and a corner material 16 arranged at the corner part in the state of attaching a sheet-like fireproof coating material 15 to the inner surface thereof beforehand. Thereafter, a spray fireproof coating material 17 is sprayed to the inner surface of the panel 4 to be a part other than the attaching part of the fireproof coating material 15 of the corner material 16 on the inner surface of the external wall 9 to be a required thickness and density. Thus, when constructing the fireproof coating to the inner surface of the external wall 9, the work of the fireproof coating by spraying to the inner surface of the corner material 16, where the fireproof coating by spraying of the spray fireproof coating material 17 is most difficult, can be omitted.

Description

本発明は、機械式立体駐車場等の耐火建築物における主要構造部となる柱や外壁等を耐火被覆するために用いる耐火建築物の耐火被覆施工方法に関するものである。   TECHNICAL FIELD The present invention relates to a fireproof construction method for a fireproof building used to fireproof a pillar, an outer wall, or the like, which is a main structure in a fireproof building such as a mechanical multistory parking lot.

機械式立体駐車場等に用いられる建築物の１つの形式として、複数の柱と、該各柱に掛け渡した桁材により骨組みとなる構造体を形成し、且つ該構造体を取り囲むように外壁を設けてなる構成とした鉄骨造の建築物がある。又、この種の鉄骨造の建築物では、外壁を構築するための外壁材として、特殊塗装鋼板等の薄い鋼板製の外壁材が用いられることがある。   As one type of building used for mechanical multistory parking lots, etc., a structure that becomes a framework is formed by a plurality of columns and girders spanned over each column, and the outer wall is surrounded by the structure. There is a steel-framed building that has a structure constructed of In this type of steel structure building, an outer wall material made of a thin steel plate such as a specially coated steel plate may be used as an outer wall material for constructing the outer wall.

図６は鉄骨造の建築物の一例として、機械式立体駐車場を示すもので、かかる機械式立体駐車場を建築する場合は、先ず、機械式立体駐車場の四隅となる位置に立設させた柱部材１と、該柱部材１間に取り付けた図示しない梁部材により骨組構造体３を形成する。次に、上記骨組構造体３の内側に、図示しない機械式駐車装置を設ける。   FIG. 6 shows a mechanical multistory parking lot as an example of a steel structure building. When constructing such a mechanical multistory parking lot, first, it is erected at positions that are four corners of the mechanical multistory parking lot. A frame structure 3 is formed by the column members 1 and beam members (not shown) attached between the column members 1. Next, a mechanical parking device (not shown) is provided inside the framework structure 3.

次いで、隣接する柱部材１の外側に、胴縁部材（桁材）２を多段に掛け渡すようにブラケット等の所要の取付手段を介して取り付ける。   Subsequently, it attaches to the outer side of the adjacent pillar member 1 via required attachment means, such as a bracket, so that the trunk edge member (spar) 2 may be spanned in multiple stages.

その後、外壁材として、所定の幅寸法で上下方向に所要寸法延びる薄い鋼板製の波板状のパネル４を、上記胴縁部材２の四方の側面に沿わせて水平方向に並べて配置すると共に、該各パネル４に個別に取り付けてあるフック５を介して上記骨組構造体３の最下段の胴縁部材２に順次係止させた後、上記各フック５を胴縁部材２にビス止めして上記各パネル４を胴縁部材２に固定する。   After that, as the outer wall material, the corrugated panel 4 made of a thin steel plate extending in the vertical direction with a predetermined width dimension is arranged side by side in the horizontal direction along the four side surfaces of the trunk edge member 2, and After sequentially engaging with the lowermost trunk edge member 2 of the frame structure 3 via hooks 5 individually attached to the respective panels 4, the respective hooks 5 are screwed to the trunk edge member 2. Each panel 4 is fixed to the trunk edge member 2.

しかる後、上記骨組構造体３の各コーナー部６において隣接する２枚のパネル４に、該各パネル４の端部間の隙間を埋めるためのコーナー材としての隅包板７を、外側から上記２枚のパネル４に所要量ずつ重なるように配置すると共に、該隅包板７をねじ部材８により上記胴縁部材２に取り付けて、上記骨組構造体３の各コーナー部６に配置された４つの隅包板７と、該各隅包板７の間を繋ぐ各パネル４からなる最下段の外壁９を完成させ、以下同様の手順で、順次上段の外壁９を完成させるようにしてある（たとえば、特許文献１参照）。   Thereafter, a corner wrapping plate 7 as a corner material for filling a gap between the end portions of each panel 4 is provided on the two adjacent panels 4 in each corner portion 6 of the frame structure 3 from the outside. The four pieces of panels 4 are arranged so as to overlap each other by a required amount, and the corner wrapping plate 7 is attached to the trunk edge member 2 by a screw member 8 and is arranged at each corner portion 6 of the skeleton structure 3. The bottom outer wall 9 composed of two corner wrapping plates 7 and the panels 4 connecting the corner wrapping plates 7 is completed, and then the upper outer wall 9 is sequentially completed in the same procedure ( For example, see Patent Document 1).

ところで、建築基準法における耐火建築物には、学校、体育館、病院等の他、機械式立体駐車場等の自動車車庫も含まれる。このため、機械式立体駐車場においても建築基準法の耐火建築物の基準を満たすために、建築基準法上に規定されている主要構造部としての柱や外壁等を耐火被覆して耐火構造にする必要がある。   By the way, fireproof buildings in the Building Standard Law include not only schools, gymnasiums, hospitals, etc. but also automobile garages such as mechanical multistory parking lots. For this reason, in order to satisfy the standards of fire-resistant buildings of the Building Standards Act even in mechanical multistory parking lots, the pillars and outer walls, etc., as the main structural parts specified in the Building Standards Act are covered with fire-resistant structures. There is a need to.

そのため、上記図６に示した機械式立体駐車場のような薄い鋼板製のパネル４及び隅包板７からなる外壁９を備えた鉄骨造の建築物を耐火構造とする場合は、建築基準法上の主要構造部となる柱部材１や外壁９の内面に、耐火被覆を設ける必要がある。   Therefore, when a steel structure building having an outer wall 9 comprising a thin steel plate panel 4 and a corner wrapping plate 7 such as the mechanical multistory parking lot shown in FIG. It is necessary to provide a fireproof coating on the inner surface of the pillar member 1 and the outer wall 9 which are the upper main structural portions.

上記のような建築物の柱や外壁等を耐火被覆する手法としては、柱や完成した外壁に対し、ポンプにより圧送されるロックウール等を含有する吹付け用耐火被覆材を、ホース等を介して吹付けて、上記柱や外壁の内面に、上記吹付け用耐火被覆材を所要の厚さ、密度で付着させるようにする吹付け方式の耐火被覆施工方法が、複雑な形状のものや不定形なものに適用し易いという観点から広く一般的に採用されている（たとえば、特許文献２参照）。   As a method of fireproofing the pillars and outer walls of the building as described above, a fireproof covering material for spraying containing rock wool etc. pumped by a pump to the pillars and the finished outer wall is provided via a hose or the like. The spray-type fire-resistant coating construction method in which the above-mentioned fire-resistant coating material for spraying is adhered to the inner surfaces of the pillars and the outer wall with the required thickness and density is not suitable for complicated shapes or Widely and generally adopted from the viewpoint that it can be easily applied to a standard one (for example, see Patent Document 2).

なお、耐火建築物の主要構造部を耐火被覆する施工方法の他の例としては、たとえば、図７に示すように、天井スラブ１１に取り付けるためのＨ形断面の鉄骨梁１２を、上記天井スラブ１１と当接する上部フランジ面１２ａと、上部フランジのエッジ面１２ｂと、鉄骨梁１２の両端支持部１２ｃとを残してフェルト状（シート状）の耐火被覆材１３で予め被覆した後、上記天井スラブ１１に取り付けるようにすることが提案されている（たとえば、特許文献３参照）。   In addition, as another example of the construction method for fireproof covering the main structural part of the fireproof building, for example, as shown in FIG. 7, the steel beam 12 having an H-shaped cross section to be attached to the ceiling slab 11 is used as the ceiling slab. 11 is previously covered with a felt-like (sheet-like) fireproof covering material 13 except for an upper flange surface 12a that contacts the upper edge 11, an edge surface 12b of the upper flange, and both end support portions 12c of the steel beam 12, and then the ceiling slab. 11 (see, for example, Patent Document 3).

ところが、近年、機械式立体駐車場では、建屋をコンパクトにすることが求められるようになってきており、そのために、上記図６に示したような機械式立体駐車場の建屋では、コーナー部６において、柱部材１とその外側に配置されている外壁９との間隔が狭くなる傾向にある。   However, in recent years, in a mechanical multi-story parking lot, it has been required to make the building compact. For this reason, in the mechanical multi-story parking building as shown in FIG. In FIG. 2, the interval between the column member 1 and the outer wall 9 disposed outside the column member 1 tends to be narrowed.

このように機械式立体駐車場の建屋のコーナー部６における柱部材１と外壁９との間隔が狭くなると、該機械式立体駐車場について、上記特許文献２に記載された吹付け方式の耐火被覆施工方法を用いて耐火被覆を施工しようとする場合、上記柱部材１と外壁９との隙間に吹付け用耐火被覆材を吹付けるためのホース等を挿入することが困難になるというのが実状である。   Thus, when the space | interval of the pillar member 1 and the outer wall 9 in the corner part 6 of the building of a mechanical multistory parking space becomes narrow, about the said mechanical multistory parking lot, the fireproof coating of the spraying system described in the said patent document 2 When trying to construct a fireproof coating using a construction method, it is difficult to insert a hose or the like for spraying a fireproof coating material for spraying into the gap between the column member 1 and the outer wall 9. It is.

そのために、建屋のコーナー部６では、外壁９の内面や、柱部材１における外壁９に臨む側面に、吹付け用耐火被覆材を吹付け施工して所要の厚さ、密度で付着させるための作業が実施し難くなることから、該コーナー部６の耐火被覆の施工に時間を要してしまい、よって、上記機械式立体駐車場全体の耐火被覆を施工するための作業時間が嵩んでしまう。   Therefore, in the corner portion 6 of the building, a fireproof coating material for spraying is sprayed on the inner surface of the outer wall 9 or the side surface facing the outer wall 9 of the column member 1 so as to adhere to the required thickness and density. Since it becomes difficult to carry out the work, it takes time to apply the fireproof coating on the corner portion 6, and thus the work time for applying the fireproof coating on the entire mechanical multistory parking lot increases.

又、建屋のコーナー部６での上記吹付け用耐火被覆材を吹付ける作業は、狭い隙間での作業になるため、該吹付け用耐火被覆材の吹付け量の管理にも手間がかかる。   Moreover, since the operation | work which sprays the said fireproof coating material for spraying in the corner part 6 of a building becomes a work in a narrow clearance gap, management of the spraying quantity of this fireproof coating material for spraying also takes time.

なお、上記特許文献３に記載されたものは、Ｈ形断面の鉄骨梁１２を予めフェルト状の耐火被覆材１３で被覆した後、天井スラブ１１に取り付けるようにするものであるため、内側に耐火被覆材を取り付けたコーナー材に隣接する外壁材に対し、耐火被覆材を吹付けるようにするような考えのものではなく、又、このような考えを示唆するものでもない。   In addition, since what was described in the said patent document 3 coat | covers the H-shaped cross-section steel beam 12 with the felt-like fireproof covering material 13 previously, and attaches it to the ceiling slab 11, it is fireproof inside. It is not the idea of spraying the fireproof coating material on the outer wall material adjacent to the corner material to which the coating material is attached, nor does it suggest such an idea.

しかも、上記特許文献３に示されたフェルト状の耐火被覆材１３は、シート形状であるため、上記Ｈ形断面の鉄骨梁１２のような単純な形状の部材に巻き付ける場合に適しているとしても、複雑な形状のものに適用するには加工が必要になる。更に、上記フェルト状の耐火被覆材１３は、複雑な形状のものや不定形なものに適用し易いという利点が広く一般的に知られている吹付け用耐火被覆材に比してコストが嵩む。よって、特許文献３に示されたものは、上記フェルト状の耐火被覆材１３を、薄い鋼板製のパネルとコーナー材を組み合わせて形成されるような複雑な構造の建築物の外壁の耐火被覆に適用する考えを何ら示唆するものではない。   Moreover, since the felt-like fireproof covering material 13 shown in Patent Document 3 has a sheet shape, it may be suitable for winding around a simple-shaped member such as the steel beam 12 having the H-shaped cross section. In order to apply to complicated shapes, processing is required. Further, the felt-shaped fireproof covering material 13 has an advantage that it can be easily applied to a complex shape or an irregular shape, and the cost is higher than a widely known fireproof covering material for spraying. . Therefore, what was shown by patent document 3 is the above-mentioned felt-like fireproof covering material 13 to the fireproof covering of the outer wall of the building of a complicated structure formed by combining a thin steel plate panel and a corner material. It does not suggest any ideas to apply.

そこで、本発明は、耐火建築物におけるコーナー部に設置された柱部材と、その外側に設けられる外壁との間隔が狭くても、該耐火建築物に対する耐火被覆の施工を短時間で行うことができ、且つ吹付け用耐火被覆材の吹付け量の管理に要する手間を減らすことができるようにするための耐火建築物の耐火被覆施工方法を提供しようとするものである。   Therefore, the present invention can perform the construction of the fireproof coating on the fireproof building in a short time even if the interval between the pillar member installed at the corner portion in the fireproof building and the outer wall provided on the outside thereof is narrow. An object of the present invention is to provide a fireproof coating construction method for a fireproof building so as to be able to reduce the labor required for managing the spraying amount of the fireproof coating material for spraying.

本発明は、上記課題を解決するために、請求項１に対応して、耐火建築物のコーナー部となる位置に立設させた柱部材を耐火構造とし、上記耐火建築物のコーナー部となる位置に配置するコーナー材を、予め内面に耐火被覆材を取り付けた状態として上記コーナー部に配置するようにし、上記各コーナー材に連結して外壁を構成する外壁材に上記各コーナー材を連結して外壁を構築し、次いで、上記外壁の内面における上記コーナー材に取り付けてある耐火被覆材により被覆された部分を除く領域に、吹付け用耐火被覆材を吹付けて、上記外壁の内面を、上記コーナー材に取り付けてある耐火被覆材と上記吹付け用耐火被覆材により全面に亘り被覆する方法とする。   In order to solve the above-mentioned problem, the present invention has a fire-resistant structure in which a pillar member erected at a position to be a corner portion of a fireproof building is a corner portion of the fireproof building. The corner material to be arranged at the position is arranged in the corner portion with the fireproof covering material attached to the inner surface in advance, and each corner material is connected to the outer wall material constituting the outer wall by connecting to each corner material. The outer wall is constructed, and then sprayed with a fireproof coating material for spraying on a region excluding the portion covered with the fireproof coating material attached to the corner material on the inner surface of the outer wall, the inner surface of the outer wall is A method of covering the entire surface with the fireproof covering material attached to the corner material and the fireproof covering material for spraying.

又、上記構成において、コーナー材の両側端部に、外壁材の端部に設けてある係合部に係合させるための係合部をそれぞれ設けて、該各係合部を含むコーナー材の内面に耐火被覆材を取り付けるようにする。   Further, in the above-described configuration, an engaging portion for engaging with an engaging portion provided at an end portion of the outer wall material is provided at both end portions of the corner material, and the corner material including the engaging portions is provided. Attach fireproof coating on the inner surface.

本発明の耐火建築物の耐火被覆施工方法によれば、以下の如き優れた効果を発揮する。
（１）耐火建築物のコーナー部となる位置に立設させた柱部材を耐火構造とし、上記耐火建築物のコーナー部となる位置に配置するコーナー材を、予め内面に耐火被覆材を取り付けた状態として上記コーナー部に配置するようにし、上記各コーナー材に連結して外壁を構成する外壁材に上記各コーナー材を連結して外壁を構築し、次いで、上記外壁の内面における上記コーナー材に取り付けてある耐火被覆材により被覆された部分を除く領域に、吹付け用耐火被覆材を吹付けて、上記外壁の内面を、上記コーナー材に取り付けてある耐火被覆材と上記吹付け用耐火被覆材により全面に亘り被覆するようにしてあるので、耐火建築物のコーナー部において柱部材と外壁との隙間を通しての吹付け用耐火被覆材の吹付けによる耐火被覆の施工が最も困難なコーナー材の内面に対する吹付けによる耐火被覆の施工作業を省略することができ、これにより、耐火建築物の主要構造部に対して行う耐火被覆の施工を短時間に行うことができる。又、吹付け用耐火被覆材の吹付け量の管理にかかる手間も減らすことができる。
（２）又、外壁の内面におけるコーナー材に取り付けてある耐火被覆材により被覆された部分を除く領域に対して吹付け用耐火被覆材を吹付けるようにしてあるので、外壁の内面に吹付けて付着させた吹付け用耐火被覆材と、上記コーナー材に予め取り付けてある耐火被覆材との間に隙間が生じる虞を容易に且つ確実に防ぐことができる。更に、柱部材を耐火構造にしてあると共に、コーナー材には耐火被覆材を取り付けるようにしてあるので、建築現場で用いる吹付け用耐火被覆材の量を減らすことが可能になる。
（３）上記（１）（２）により、本発明の耐火被覆施工方法は、コーナー部において柱部材とその外側に配置されている外壁との間隔が狭く設定される傾向にある機械式立体駐車場の建屋のような耐火建築物の耐火被覆の施工に適したものとすることができる。
（４）コーナー材の両側端部に、外壁材の端部に設けてある係合部に係合させるための係合部をそれぞれ設けて、該各係合部を含むコーナー材の内面に耐火被覆材を取り付けるようにすることにより、コーナー材に取り付ける耐火被覆材の面積を広く取ることができるため、耐火建築物の主要構造部に対して行う耐火被覆の施工をより短時間に行うことができる。しかも、コーナー材の内面を予め全面に亘って耐火被覆材により被覆した状態で外壁の構築に供することができるようになるため、建築現場で用いる吹付け用耐火被覆材の量をより減らすことができ、又、該コーナー材の内面に対して上記耐火被覆材を取り付ける作業に要する手間及び時間の低減化を図る効果が期待できる。 According to the fireproof coating construction method for fireproof buildings of the present invention, the following excellent effects are exhibited.
(1) The pillar member erected at the position that becomes the corner portion of the fireproof building is made into a fireproof structure, and the corner material that is placed at the position that becomes the corner portion of the fireproof building is previously attached with the fireproof covering material on the inner surface. As the state, it is arranged at the corner part, and the outer wall is constructed by connecting the corner material to the outer wall material constituting the outer wall by connecting to the respective corner materials, and then the corner material on the inner surface of the outer wall. A fireproof coating material for spraying is sprayed on an area excluding a portion covered with the fireproof coating material that is attached, and the fireproof coating material and the fireproof coating for spraying are attached to the inner surface of the outer wall on the corner material. Therefore, it is best to apply fireproof coating by spraying the fireproof coating material through the gap between the pillar member and the outer wall at the corner of the fireproof building. It is possible to omit the installation work of the refractory coating by spraying with the inner surface of the hard corner member, thereby, the construction of the refractory coating to be performed on the main structure portion of the fire-resistant buildings can be performed in a short time. Moreover, the effort concerning management of the spraying amount of the fireproof coating material for spraying can be reduced.
(2) In addition, since the fireproof coating material for spraying is sprayed on the area excluding the portion covered with the fireproof coating material attached to the corner material on the inner surface of the outer wall, spraying is performed on the inner surface of the outer wall. Therefore, it is possible to easily and reliably prevent a gap from being generated between the fireproof coating material for spraying attached thereto and the fireproof coating material previously attached to the corner material. Furthermore, since the pillar member has a fireproof structure, and the corner material is provided with a fireproof coating material, the amount of the fireproof coating material for spraying used at the construction site can be reduced.
(3) According to the above (1) and (2), the fireproof coating construction method of the present invention is a mechanical multi-story parking in which the interval between the column member and the outer wall arranged outside thereof tends to be set narrow in the corner portion. It can be suitable for the construction of fireproof coatings for fireproof buildings such as car buildings.
(4) An engagement portion for engaging with an engagement portion provided at an end portion of the outer wall material is provided at both end portions of the corner material, and fire resistance is provided on the inner surface of the corner material including each engagement portion. By attaching the covering material, it is possible to increase the area of the fireproof covering material attached to the corner material, so that the construction of the fireproof covering applied to the main structure of the fireproof building can be performed in a shorter time. it can. Moreover, since the outer wall can be used for construction of the outer wall in a state where the entire inner surface of the corner material is previously covered with the fireproof coating material, the amount of the fireproof coating material for spraying used at the construction site can be further reduced. Moreover, the effect which reduces the effort and time which are required for the operation | work which attaches the said fireproof covering material with respect to the inner surface of this corner material can be anticipated.

図１乃至図５は本発明の耐火建築物の耐火被覆施工方法の実施の一形態として、耐火建築物としての機械式立体駐車場の建屋に対する耐火被覆施工に適用する場合の例を示すもので、以下のようにしてある。   FIG. 1 thru | or 5 shows the example in the case of applying to the fireproof coating construction with respect to the building of the mechanical multistory parking lot as a fireproof building as one Embodiment of the fireproof coating construction method of the fireproof building of this invention. It is as follows.

すなわち、本発明の耐火建築物の耐火被覆施工方法は、図６に示した機械式立体駐車場と同様に、先ず、機械式立体駐車場の四隅となる位置に柱部材１をそれぞれ立設させた後、該各柱部材１に、シート状（フェルト状）の耐火被覆材１４を取り付ける。   That is, according to the fireproof construction method for fireproof buildings of the present invention, as in the case of the mechanical multilevel parking lot shown in FIG. After that, a sheet-like (felt-like) fireproof covering material 14 is attached to each column member 1.

次に、上記柱部材１間に梁部材１８を取り付けて、該柱部材１と梁部材１８からなる骨組構造体３を構成し、次いで、上記柱部材１に、胴縁部材２を図示しないブラケットを介して多段に掛け渡した後、上記骨組構造体３の外側に、予め内面にシート状（フェルト状）の耐火被覆材１５を取り付けた状態で機械式立体駐車場の建屋の各コーナー部６と対応する個所に配置させる薄い鋼板製のコーナー材１６と、該各コーナー材１６同士の間に複数枚ずつ並べて配置した外壁材としての薄い鋼板製の波板状のパネル４からなる外壁９を構築する。   Next, a beam member 18 is attached between the column members 1 to form a frame structure 3 composed of the column member 1 and the beam member 18, and then the trunk member 2 is not shown in the bracket. After being spanned in multiple stages, each corner portion 6 of the building of the mechanical multi-story parking lot with a sheet-like (felt-like) fireproof covering 15 attached to the inner surface in advance on the outer side of the framework structure 3 A thin steel plate corner material 16 disposed at a corresponding location, and an outer wall 9 composed of a corrugated panel 4 made of thin steel plate as an outer wall material arranged side by side between each corner material 16.

It is assumed that it has been set.

次いで、図３に示すように、図６に示したと同様の薄い鋼板製の波板状の外壁材としての波板状のパネル４を、上記骨組構造体３の四方の側面に沿わせて水平方向に並べて配置すると共に、隣接するパネル４の突合せ端部同士を、該各パネル４の幅方向の一端側と他端側にそれぞれ設けてある雄形状の係合部４ａと雌形状の係合部４ｂとを互いに係合させながら、該各パネル４に個別に取り付けてあるフック５を介して上記胴縁部材２に順次係止させた後、上記各フック５を胴縁部材２にビス止めすることで、上記各パネル４を対応する胴縁部材２に固定する。なお、この際、上記骨組構造体３のコーナー部６に最も接近して配置される各パネル４については、該各パネル４のコーナー部６寄りのすべての端部が、図３に示すように、後述するコーナー材１６の両側端部に設ける雌形状の係合部１６ａ（図４参照）に対して外側から係合可能な雄形状の係合部４ａになるようにしてある。
又、上記骨組構造体３のコーナー部６に最も接近して配置される各パネル４におけるフック５の取付位置は、図３に示す如く、該各パネル４における柱部材１と対面する部分から外れた位置になるようにして、該フック５が柱部材１に取り付けてある耐火被覆材１４と干渉しないようにしてある。（図３では、図示する便宜上、各柱部材１の間の梁部材１８（図２参照）の記載は省略してある。後述する図４、図５も同様。）
又、上記コーナー材１６は、平面形状を上記骨組構造体３の各コーナー部６において隣接するパネル４の端部間の隙間を埋める略Ｌ字形状とし、且つ上記骨組構造体３のコーナー部６に最も接近して配置される各パネル４のコーナー部６寄り端部に設けてある雄形状の係合部４ａを内側（骨組構造体３に近接する側）から受けるための雌形状の係合部１６ａが両側端部に設けてあり、このコーナー材１６の内面側に、図４に示すように、上記柱部材１に巻き付けたのと同様のシート状（フェルト状）の耐火被覆材１５を、工場や建築現場等で接着剤等により予め全幅に亘り貼り付けておく。 Next, as shown in FIG. 3, a corrugated panel 4 as a corrugated outer wall material made of a thin steel plate similar to that shown in FIG. 6 is placed horizontally along the four side surfaces of the framework structure 3. The male engaging portions 4a and the female engaging portions, which are arranged side by side, are provided on the one end side and the other end side in the width direction of the panels 4 respectively. The hooks 5 are individually locked to the trunk edge member 2 through hooks 5 individually attached to the panels 4 while being engaged with each other, and then the hooks 5 are screwed to the trunk edge member 2. Thus, each panel 4 is fixed to the corresponding trunk edge member 2. At this time, with respect to each panel 4 arranged closest to the corner portion 6 of the frame structure 3, all the end portions near the corner portion 6 of each panel 4 are as shown in FIG. A male-shaped engagement portion 4a that can be engaged from the outside with respect to a female-shaped engagement portion 16a (see FIG. 4) provided at both end portions of the corner member 16 to be described later.
Further, the hook 5 is attached to each panel 4 arranged closest to the corner portion 6 of the frame structure 3 as shown in FIG. Thus, the hook 5 does not interfere with the fireproof covering material 14 attached to the column member 1. (In FIG. 3, the description of the beam member 18 (refer FIG. 2) between each pillar member 1 is abbreviate | omitted for convenience of illustration. The same applies to FIG. 4, FIG. 5 mentioned later.)
The corner member 16 has a planar shape substantially L-shaped to fill a gap between the end portions of the adjacent panels 4 in each corner portion 6 of the framework structure 3, and the corner portion 6 of the framework structure 3. Female-shaped engagement for receiving the male-shaped engaging portion 4a provided at the end close to the corner portion 6 of each panel 4 that is disposed closest to the frame from the inner side (side close to the frame structure 3) A portion 16a is provided at both end portions, and a sheet-like (felt-like) fireproof covering material 15 similar to that wound around the column member 1 is provided on the inner surface side of the corner member 16 as shown in FIG. Affixed in advance at the factory or construction site with an adhesive or the like over the entire width.

その後、内面にシート状の耐火被覆材１５を取り付けた状態としてある上記コーナー材１６を、上記骨組構造体３の各コーナー部６に配置させる。この際、上記骨組構造体３のコーナー部６に最も接近して配置される各パネル４のコーナー部６寄りの端部を外側へ撓ませた状態で上記コーナー材１６をコーナー部６に配置するか、あるいは、上記コーナー材１６を、上記骨組構造体３のコーナー部６に最も接近して配置される各パネル４に対して上下方向の片側からスライドさせるようにしてコーナー部６に配置することで、上記コーナー材１６の両側端部の雌形状の係合部１６ａに対し、上記骨組構造体３のコーナー部６に最も接近して配置されている各パネル４のコーナー部６寄り端部の雄形状の係合部４ａを係合させるようにする。次いで、この状態で、上記コーナー材１６を、その両側の各パネル４に接合して該各パネル４を介して上記胴縁部材２に対して固定することにより、上記各コーナー材１６と、それぞれのコーナー材１６同士の間を繋ぐ複数枚のパネル４からなる外壁９を組み立てるようにする。以下同様の手順で、順次上段の外壁９を組み立て、上記機械式立体駐車場の建屋の外壁９を構築する。   Thereafter, the corner material 16 having the sheet-like fireproof covering material 15 attached to the inner surface is disposed at each corner portion 6 of the framework structure 3. At this time, the corner material 16 is arranged in the corner portion 6 in a state where the end portion near the corner portion 6 of each panel 4 arranged closest to the corner portion 6 of the frame structure 3 is bent outward. Alternatively, the corner material 16 is arranged at the corner portion 6 so as to slide from one side in the vertical direction with respect to each panel 4 arranged closest to the corner portion 6 of the frame structure 3. Thus, with respect to the female engaging portions 16a at both end portions of the corner member 16, the end portions near the corner portions 6 of the panels 4 arranged closest to the corner portions 6 of the frame structure 3 are arranged. The male engaging portion 4a is engaged. Next, in this state, the corner members 16 are joined to the panels 4 on both sides of the corner members 16 and fixed to the trunk edge member 2 via the panels 4, respectively. The outer wall 9 composed of a plurality of panels 4 connecting the corner members 16 is assembled. Thereafter, the upper outer wall 9 is sequentially assembled in the same procedure, and the outer wall 9 of the mechanical multilevel parking garage building is constructed.

しかる後、上記構築された外壁９の内面における上記各コーナー材１６の上記シート状の耐火被覆材１５で予め被覆された個所を除く部分の全面、すなわち、各パネル４の内面の全面に対し、図５に示す如く、図示しないポンプで圧送させた上記吹付け用耐火被覆材１７を、図示しないホース等を介して吹付け施工し、外壁９を構築している該各パネル４の内面に、上記吹付け用耐火被覆材１７を所要の厚さ、密度になるように付着させるようにする。この際、上記骨組構造体３のコーナー部６に最も接近して配置されている各パネル４の内面に上記吹付け用耐火被覆材１７を吹付けるときには、上記各コーナー材１６に貼り付けてあるシート状の耐火被覆材１５の端部にも密着するように吹付けるようにすることで、上記各パネル４の内面に吹付けた吹付け用耐火被覆材１７と、コーナー材１６に取り付けてある耐火被覆材１５との間に隙間が生じないようにする。   Thereafter, with respect to the entire surface of the inner surface of the constructed outer wall 9 excluding the portion previously covered with the sheet-like fireproof coating material 15 of the corner material 16, that is, the entire inner surface of each panel 4. As shown in FIG. 5, the fireproof coating material 17 for spraying that has been pumped by a pump (not shown) is sprayed through a hose or the like (not shown), and the inner surface of each panel 4 constructing the outer wall 9, The spraying fireproof coating material 17 is adhered to a required thickness and density. At this time, when spraying the fireproof coating material 17 for spraying on the inner surface of each panel 4 arranged closest to the corner portion 6 of the frame structure 3, it is stuck to each corner material 16. It is attached to the fireproof coating material 17 for spraying sprayed on the inner surface of each panel 4 and the corner material 16 by spraying the sheet-shaped fireproof coating material 15 in close contact with the end portion. A gap should not be formed between the fireproof covering material 15.

以上により、上記外壁９の内面を、上記各コーナー材１６に取り付けてある上記シート状の耐火被覆材１５と、上記各パネル４の内側に付着させた吹付け用耐火被覆材１７によって全面に亘って覆うようにして、耐火被覆を完成するようにする。   As described above, the inner surface of the outer wall 9 is spread over the entire surface by the sheet-like fireproof covering material 15 attached to each corner member 16 and the spraying fireproof covering material 17 attached to the inside of each panel 4. To complete the refractory coating.

このように、本発明の耐火建築物の耐火被覆施工方法によれば、耐火建築物としての機械式立体駐車場の建屋の四隅の各コーナー部６となる位置に立設させた柱部材１に、シート状の耐火被覆材１４をそれぞれ全周に亘り巻き付けて耐火構造とし、その後、該各柱部材１の外側で、内面に予め耐火被覆材１５を貼り付けた状態のコーナー材１６と、パネル４を用いて外壁９を構築するようにしてあるため、該構築された外壁９の内面側に吹付け用耐火被覆材１７を吹付け施工する際には、上記機械式立体駐車場の建屋のコーナー部６において柱部材１と外壁９との隙間を通しての吹付け用耐火被覆材１７の吹付け施工が最も困難となるコーナー材１６の内面に対する吹付け施工による耐火被覆の工程を省略することができる。したがって、耐火建築物である上記機械式立体駐車場の建屋における主要構造部全体に対する耐火被覆の施工を短時間に行うことができる。しかも、上記したように、コーナー部６において吹付け用耐火被覆材１７の吹付け施工が最も困難となるコーナー材１６の内面に対する吹付け施工が不要なため、上記吹付け用耐火被覆材１７の吹付け量の管理にかかる手間も減らすことができる。   Thus, according to the fireproof covering construction method for a fireproof building of the present invention, the column member 1 is erected at positions corresponding to the corner portions 6 of the four corners of the building of the mechanical multistory parking lot as the fireproof building. The sheet-like fire-resistant coating material 14 is wound around the entire circumference to form a fire-resistant structure, and then the corner material 16 in a state in which the fire-resistant coating material 15 is pasted to the inner surface in advance on the outer side of each column member 1, 4, the outer wall 9 is constructed. Therefore, when the fireproof covering material 17 for spraying is sprayed on the inner surface side of the constructed outer wall 9, It is possible to omit the process of fireproof coating by spraying the inner surface of the corner material 16 where the spraying of the fireproof coating material 17 for spraying through the gap between the column member 1 and the outer wall 9 at the corner portion 6 is most difficult. it can. Therefore, the fireproof coating can be applied in a short time to the entire main structure in the building of the mechanical multilevel parking garage that is a fireproof building. In addition, as described above, since the spraying operation to the inner surface of the corner material 16 where the spraying of the spraying fireproof coating material 17 is most difficult in the corner portion 6 is unnecessary, the spraying fireproof coating material 17 It is possible to reduce the time and effort required to manage the spray amount.

又、柱部材１とコーナー材１６に耐火被覆材１４と１５を取り付けるようにしてあるので、建築現場で吹付け施工に用いる吹付け用耐火被覆材１７の量を減らすことができる。   Moreover, since the fireproof covering materials 14 and 15 are attached to the column member 1 and the corner member 16, the amount of the fireproof covering material 17 for spraying used for spraying construction at the construction site can be reduced.

更に、柱部材１には、予めシート状の耐火被覆材１４を全周に亘り巻き付けるようにしてあるので、該柱部材１に対する吹付け用耐火被覆材１７の吹付け施工も省略することができる。   Further, since the sheet-like fireproof coating material 14 is wound around the column member 1 over the entire circumference, the spraying of the spraying fireproof coating material 17 to the column member 1 can be omitted. .

更に又、各パネル４に対しては、吹付け用耐火被覆材１７を吹付けることにより耐火被覆を施工するようにしてあるので、パネル４に吹付けられた上記吹付け用耐火被覆材１７と、コーナー材１６に貼り付けた耐火被覆材１５との間に隙間が生じる虞を容易に且つ確実に防止することができる。   Furthermore, since the fireproof coating material 17 is applied to each panel 4 by spraying the fireproof coating material 17 for spraying, the fireproof coating material 17 for spraying sprayed on the panel 4 and Further, it is possible to easily and surely prevent a gap from being generated between the corner member 16 and the fireproof covering material 15 attached to the corner material 16.

又、コーナー材１６の両側端部には、パネル４端部の雄形状の係合部４ａを内側から受けるための雌形状の係合部１６ａがそれぞれ設けてあるので、該各係合部１６ａを含むコーナー材１６の内面の全面に、上記シート状の耐火被覆材１５を貼り付けることができて、該コーナー材１６の内面に対する上記シート状の耐火被覆材１５の貼り付ける作業に要する手間及び時間の低減化を図る効果が期待できる。   Moreover, since the female-shaped engaging part 16a for receiving the male-shaped engaging part 4a of the panel 4 edge part from the inner side is each provided in the both-sides edge part of the corner material 16, each said engaging part 16a The sheet-like fireproof coating material 15 can be attached to the entire inner surface of the corner material 16 including the work required for the operation of attaching the sheet-shaped fireproof coating material 15 to the inner surface of the corner material 16 and The effect of reducing time can be expected.

以上により、本発明の耐火建築物の耐火被覆施工方法は、建屋のコンパクト化が図られることに伴って、コーナー部６において柱部材１とその外側に配置されている外壁９との間隔が狭くなる傾向にある機械式立体駐車場の耐火被覆の施工に適したものとすることができる。   As described above, according to the fireproof construction method for fireproof buildings of the present invention, the space between the column member 1 and the outer wall 9 disposed outside the corner portion 6 is narrow as the building is made compact. It can be made suitable for construction of fireproof coatings in mechanical multistory parking lots.

なお、本発明は上記実施の形態のみに限定されるものではなく、上記実施の形態では、耐火建築物の一例としての機械式立体駐車場の建屋における主要構造部に対して耐火被覆を施工する場合について説明したが、建築物のコーナー部に立設された柱部材１の外側で、コーナー材１６とパネル４の如き外壁材からなる外壁９を構築するようにしてある耐火建築物であれば、機械式立体駐車場以外のいかなる使用目的、いかなる形式の耐火建築物の主要構造部に対して耐火被覆を施工する場合にも適用してよい。   In addition, this invention is not limited only to the said embodiment, In the said embodiment, a fireproof coating is applied with respect to the main structure part in the building of a mechanical multistory parking lot as an example of a fireproof building. As for the case described above, if it is a fireproof building in which the outer wall 9 made of the outer wall material such as the corner material 16 and the panel 4 is constructed outside the column member 1 standing at the corner of the building, The present invention may be applied to any use purpose other than a mechanical multistory parking lot, and when a fireproof coating is applied to a main structure portion of any type of fireproof building.

又、上記実施の形態では、柱部材１をＨ形鋼とした場合について説明したが、柱部材１は他の構造鋼でもよい。   Moreover, although the said embodiment demonstrated the case where the column member 1 was made into H-section steel, the column member 1 may be another structural steel.

外壁９の構築を開始する前に柱部材１に取り付ける耐火被覆材１４は、前記したように、柱部材１の全周に亘って巻き付けることが好ましいが、柱部材１における耐火建築物のコーナー側に臨む側面（後の工程で構築する外壁９に対峙する側面）のみに耐火被覆材１４を取り付けた状態として、その外側で外壁９を構築し、その後、柱部材１の残りの部分の耐火被覆を、外壁９のパネル４の内面と同様の吹付け用耐火被覆材１７の吹付け施工により行うようにしてもよい。更に、柱部材１における少なくとも耐火建築物のコーナー側に臨む側面に確実に取り付けることができるようにしてあれば、外壁９の構築を開始する前に柱部材１に取り付ける耐火被覆材は、板状やその他、シート状（フェルト状）以外のいかなる形状、形式の耐火被覆材を用いるようにしてもよい。   As described above, the fireproof covering material 14 attached to the column member 1 before starting the construction of the outer wall 9 is preferably wrapped around the entire circumference of the column member 1, but the corner side of the fireproof building in the column member 1 The outer wall 9 is constructed on the outside, with the fireproof covering 14 being attached only to the side facing the outer wall (the side facing the outer wall 9 constructed in the later step), and then the remaining part of the pillar member 1 is fireproof coated. May be performed by spraying the fireproof coating material 17 for spraying similar to the inner surface of the panel 4 of the outer wall 9. Furthermore, if the pillar member 1 can be reliably attached to at least the side facing the corner side of the fireproof building, the fireproof covering material attached to the pillar member 1 before starting the construction of the outer wall 9 is plate-shaped. In addition, any shape and type of fireproof coating material other than a sheet shape (felt shape) may be used.

更に、外壁９を構築する場合の手順としては、コーナー材１６を任意のブラケットを介して骨組構造体３の各コーナー部に固定しておいてから、後から外壁材としてのパネル４を、胴縁部材２及び上記コーナー材１６に取り付けるようにしてもよい。又、コーナー材１６の内面にシート状の耐火被覆材１５の取り付けを容易にできるようにするという観点から考えると、該コーナー材１６の両側端部には、前記したように隣接して配置される外壁材としてのパネル４の端部に設けてある雄形状の係合部４ａを内側（骨組構造体３に近接する側）から受けるための雌形状の係合部１６ａを備えることが望ましいが、隣接して配置されるパネル４の端部と係合させて該パネル４と連結できるようにしてあれば、図示した雌形状の係合部１６ａ以外のいかなる形状の係合部を設けるようにしてもよい。なお、コーナー材１６の両側端部に設けてある係合部と、隣接するパネル４の端部に設けてある対応する係合部とを係合させることに伴って、パネル４の端部の係合部の方がコーナー材１６の係合部よりも内側（骨組構造体３に近接する側）に配置されるようになる場合は、外壁９の構築前に上記コーナー材１６の内面に予め貼り付けるシート状（フェルト状）の耐火被覆材１５を、上記コーナー材１６における両側端部の係合部を除く位置にのみ貼り付けるようにすればよい。このようにしても、外壁９の構築後に該外壁９の内面に対して吹付け用耐火被覆材１７を吹付け施工することにより、上記コーナー材１６の内面に貼り付けてあるシート状の耐火被覆材１５と、吹付け施工された吹付け用耐火被覆材１７とからなる耐火被覆を、外壁９の内面全面を覆う状態で設けることができる。   Furthermore, as a procedure for constructing the outer wall 9, the corner member 16 is fixed to each corner portion of the frame structure 3 through an arbitrary bracket, and then the panel 4 as the outer wall member is later attached to the body. You may make it attach to the edge member 2 and the said corner material 16. FIG.
