Description

本発明は、配管類やケーブル等の長尺体を建物内に敷設するための長尺体支持ラックに関し、特に、長尺体支持ラック内を通じて火災や火炎が伝播するのを抑止する技術に関するものである。   The present invention relates to a long support rack for laying long bodies such as pipes and cables in a building, and more particularly to a technique for suppressing the propagation of fire and flame through the long support rack. It is.

建物の壁体（区画体の一例）に形成された貫通穴に長尺体支持ラックを挿通する場合、その貫通穴を通じて他室に火災や火炎が伝播するのを抑止するため、貫通穴の開口部と長尺体支持ラックとの間、及び、長尺体支持ラックと長尺体との間に耐火措置を施す必要がある。   When a long support rack is inserted through a through hole formed in a wall of a building (an example of a compartment), an opening in the through hole is used to suppress the propagation of fire and flame to other rooms through the through hole. It is necessary to take fireproof measures between the section and the long body support rack and between the long body support rack and the long body.

そして、従来では、長尺体支持ラックと長尺体との間に耐火措置を施すのに、長尺体支持ラックに長尺体を設置したのち、耐火措置用の軟質のパテ材や熱膨張性成形体（隙間埋め材の一例）を長尺体と長尺体支持ラックとの隙間に配設する工法が採られていた（例えば、下記特許文献１、２を参照）。   Conventionally, in order to provide a fireproof measure between the long body support rack and the long body, after installing the long body on the long body support rack, a soft putty material or thermal expansion for fireproof measures A construction method has been adopted in which a molded article (an example of a gap filling material) is disposed in a gap between a long body and a long body support rack (see, for example, Patent Documents 1 and 2 below).

特開２００７−２９１７９５号公報JP 2007-291895 A 特開平８−１２６１６４号公報JP-A-8-126164

ところが、上記従来の工法では、結果的に、長尺体支持ラック内の耐火措置よりも長尺体の設置が優先されることになって、長尺体の設置工程の後工程となる隙間埋め材の配設工程の際に長尺体支持ラックの側板部と長尺体と間に十分な量の隙間埋め材を配設することができず、そのことで、耐火性能が不十分になったり、或いは、長尺体支持ラックの側板部と貫通穴の内周面との間にも隙間埋め材を配設する非効率な工程を要する問題があった。   However, in the conventional construction method, as a result, the installation of the long body is prioritized over the fireproofing measures in the long body support rack, and the gap filling, which is a subsequent process of the long body installation process, is performed. A sufficient amount of gap filling material cannot be disposed between the side plate portion of the long body support rack and the long body during the material disposing process, which results in insufficient fire resistance. Alternatively, there is a problem that an inefficient process of disposing a gap filling material between the side plate portion of the long body support rack and the inner peripheral surface of the through hole is required.

本発明は、上述の如き実情に鑑みてなされたものであって、その主たる課題は、長尺体支持ラックの側板部と長尺体と間に十分な量の隙間埋め材を確実且つ効率的に配設し得る長尺体支持ラック内の耐火措置工法及び長尺体支持ラックを提供する点にある。   The present invention has been made in view of the above-described circumstances, and the main problem is that a sufficient amount of gap filling material is reliably and efficiently provided between the side plate portion and the long body of the long body support rack. In the point which provides the fireproof measure construction method and long body support rack in the long body support rack which can be arrange | positioned.

本発明の第１特徴構成は、長尺体支持ラック内の耐火措置工法に係り、左右の側板部と底板部を備えた長尺体支持ラックの長手方向所定位置における側板部の内面に隣接する領域に、前記底板部における長尺体の設置可能領域を制限する状態で耐火措置用の隙間埋め材を配置したのち、長尺体支持ラックの底板部に長尺体を設置する点にある。   A first characteristic configuration of the present invention relates to a fireproofing method in a long body support rack, and is adjacent to an inner surface of a side plate portion at a predetermined position in a longitudinal direction of a long body support rack having left and right side plate portions and a bottom plate portion. In the region, the gap filling material for fireproofing is disposed in a state in which the installable region of the long body in the bottom plate portion is limited, and then the long body is installed on the bottom plate portion of the long body support rack.

上記構成によれば、長尺体支持ラックの底板部に長尺体を設置するのに先立って、耐火措置用の隙間埋め材を長尺体支持ラックの側板部の内面に隣接する領域に配置するから、長尺体の設置量等に優先する形態で耐火措置用の隙間埋め材の配設量を確保することができ、これにより、所期の耐火性能を確実且つ効率的に得ることができる。   According to the above configuration, prior to installing the long body on the bottom plate portion of the long body support rack, the gap filling material for fireproof measures is disposed in the region adjacent to the inner surface of the side plate portion of the long body support rack. Therefore, it is possible to secure the arrangement amount of the gap filling material for the fireproofing measures in a form that has priority over the installation amount of the long body, and thereby, the desired fireproof performance can be obtained reliably and efficiently. it can.

本発明の第２特徴構成は、前記長尺体支持ラックの前記側板部の上部に連なる突片部又は天板部と前記底板部との間に、側板部よりも高さ寸法の大きな前記隙間埋め材を押し込むことにより、前記側板部の内面に隣接する領域に前記隙間埋め材を配設する点にある。   According to a second characteristic configuration of the present invention, the gap having a height dimension larger than that of the side plate portion between the protruding piece portion or the top plate portion and the bottom plate portion connected to the upper portion of the side plate portion of the long body support rack. The gap filling material is disposed in a region adjacent to the inner surface of the side plate portion by pushing in the filling material.

上記構成によれば、前記突片部又は天板部と前記底板部との間に側板部よりも高さ寸法の大きな前記隙間埋め材を押し込むだけで、側板部の内面に隣接する領域に隙間埋め材を配設することができるから、例えば、側板部の内面に隣接する領域で隙間埋め材を保持操作する場合や隙間埋め材を位置保持する専用の固定手段を用いる場合に比べ、隙間埋め材の配設工程の容易化を図ることができる。   According to the above configuration, the gap filling material having a height dimension larger than that of the side plate portion is pushed between the protruding piece portion or the top plate portion and the bottom plate portion, and a gap is formed in an area adjacent to the inner surface of the side plate portion. Since the filling material can be disposed, for example, the gap filling is performed in comparison with the case where the gap filling material is held and operated in the region adjacent to the inner surface of the side plate portion or the dedicated fixing means for holding the gap filling material is used. The arrangement process of the material can be facilitated.

本発明の第３特徴構成は、長尺体支持ラックに係り、左右の側板部と長尺体設置用の底板部が備えられているとともに、
前記底板部における長尺体の設置可能領域を制限するように、長手方向所定位置における前記側板部の内面に隣接する領域に隙間埋め材が設けられている点にある。 A third characteristic configuration of the present invention relates to a long body support rack, which includes left and right side plate portions and a bottom plate portion for long body installation,
A gap filling material is provided in a region adjacent to the inner surface of the side plate portion at a predetermined position in the longitudinal direction so as to limit the installable region of the long body in the bottom plate portion.

上記構成によれば、長尺体支持ラックの底板部に長尺体を設置する際には、耐火措置用の隙間埋め材が長尺体支持ラックの側板部の内面に隣接する領域に存在しているから、長尺体の設置量等に優先する形態で耐火措置用の隙間埋め材の配設量を確保することができ、これにより、所期の耐火性能を確実且つ効率的に得ることが可能になる。   According to the above configuration, when installing the long body on the bottom plate portion of the long body support rack, the gap filling material for fireproof measures exists in the region adjacent to the inner surface of the side plate portion of the long body support rack. Therefore, it is possible to secure the amount of gap filling material for fireproof measures in a form that takes precedence over the amount of installation of the long body, etc., thereby obtaining the desired fireproof performance reliably and efficiently. Is possible.
