JP-A-9-152065 Japanese Utility Model Publication No. 6-46749 Japanese Utility Model Publication No. 5-37251 Japanese Utility Model Publication No. 5-81582 JP 2007-56536 A JP-A-9-178052

  The refractory member that is arranged around the resin tube and is expanded by heat described in Patent Documents 1 to 5 expands at a location previously disposed by heating during a fire, so the resin tube is softened and dissolved. Even if the expansion progresses toward the generated space, especially when it is used for a resin standpipe such as a floor slab, a large amount of the fireproof member falls from the place where it is placed in the process of expansion. By doing so, the dropped refractory member does not contribute to fire resistance.

In addition, since the fire-resistant member that did not fall expands from the place where it was originally placed, when the state after the expansion is viewed, the fire-resistant member expands so as to have a density that can exhibit the fire-proof function in the vicinity of the place where it was originally placed. However, it is far from the point where the expansion started, especially in the vicinity of the center axis of the tube where the resin tube originally existed. It cannot be said that refractory members are present at a density of.
Further, by embedding a shape memory alloy spring in a heat-foamable refractory material as described in Patent Document 6, the softened or softened plastic tube is closed by the force of reducing the diameter of the shape memory spring. According to the means, the plastic tube may certainly shrink, but even if the foaming of the heat-foamable refractory proceeds toward the space created by the shrinkage, the heat-foamable refractory is still initially provided. As the starting point is foaming, it is difficult to reliably fill the space generated by the reduced diameter of the plastic pipe with the foamed refractory material, and as a result, sufficient fire resistance performance can not be demonstrated. Absent.

The present invention is formed from the inside by forming a refractory material layer such as a first thermally expandable member layer, a shrinkable material layer that may optionally be provided, and a refractory material layer such as a second thermally expandable member layer. It is a cylindrical fireproof closure composite material, the two thermally expandable member layers contain a thermally expandable material and a resin, rubber, or the shrinkable material layer has a heat shrinkable cylindrical resin, rubber, or The sheet may be formed with a net or hole made of a shape memory alloy.
Further, the first thermally expandable member layer may be formed with a V-shaped or U-shaped groove from the inner surface, and the expansion start temperature of the first thermally expandable member layer is T ₁ , Assuming that the shrinkage start temperature of the material layer is T ₂ and the expansion start temperature of the second thermally expandable member layer is T ₃ , T ₂ ≦ T ₁ and T ₂ ≦ T ₃ . When the temperature is equal to or higher than the softening point temperature of the resin material to be inserted into the composite material, or at the same time as or after the start of softening of the resin tube or resin-coated cable, the shrinkable material starts to shrink, and the shrinkable material It is a fireproof plugging composite material including a case where the first and second thermally expandable member layers start to expand simultaneously with or after the contraction.

  In addition, the present invention provides a pipe joint, pipe sleeve, cable sleeve inserted into an opening provided in a floor, ceiling or wall of a building, a fireproof for connecting to a floor, ceiling or wall forming the opening. A fire prevention device with a built-in composite material for closure, comprising a fixture for connecting to the pipe joint, the sleeve, the floor, the ceiling or the wall, and a surface other than the inside of the cylindrical shape of the fireproof closure composite material Is a fireproof blocking composite built-in fire prevention device formed by integrating the fixing member and the fireproof member, a location facing the fireproof plugging composite material on the upper and lower surfaces of the fireproof plugging composite material, And a fireproof closure composite material built-in fire prevention device in which a heat insulating material layer may be provided between the outer surface of the fireproof closure composite material and the fireproof member. Insert any of the fireproof plugging composites, and the fireproof plugging Non-combustible pipe joints for resin pipes, resin pipes or resin-coated cables inserted into openings provided in floors, ceilings or walls of buildings where resin pipes or resin-coated cables are inserted inside composite materials It is a sleeve.

The present invention is a cylindrical composite material having a shrinkage material layer between an inner first refractory material layer and an outer second refractory material layer. When a fire breaks out after the resin cable is inserted and installed in the building, and the resin loses its volume due to melting or disappears due to this heat, the shrinking material shrinks due to the heat during the fire. The inward force acts on the inner first refractory material layer by the contraction force. Then, at least a part of the inner first refractory material layer moves to the central portion of the original cylindrical composite material due to deformation or movement, and after that movement, the inner first refractory material layer As a result, the refractory material layer fills the space of the volume reduction or disappearance due to melting of the resin or the like.
As a result, it is possible to prevent fire flames, heat, and toxic gases from moving through the original resin pipe or resin cable portion to other floors or adjacent rooms.

In addition to the effect, the inner first refractory material layer and the outer second refractory material layer are respectively divided into an inner first thermal expandable member layer and an outer second thermally expandable member layer. In this case, the first thermally expandable member layer is pushed inward while the first thermally expandable member layer on the inside expands itself or by contraction of the heat shrinkable material. Then, it will be pushed into the space inside the cylinder.
As a result, the pressed first thermal expansion member layer is present in the inner space portion of the cylindrical composite material, or the first thermal expansion is performed in the inner space while being pressed. Since the expandable member layer is sufficiently expanded, the result of the presence of the expanded heat expandable member layer having a sufficient density inside the heated tube shape, that is, the expansion body is formed by the heat of the fire, and the tube shape As a result of the blockage of the inside, the flame, hot air, and toxic gas are blocked and cannot pass through the center of the cylinder.

  Furthermore, when such a composite material is provided on a pipe joint, a pipe sleeve, a cable sleeve, or a floor, ceiling, or wall forming the opening, which is inserted into an opening provided on the ceiling or wall of the building, Even when an object is hit by a fire, it expands by heating, and the opening is sealed by an expanding body that securely seals the entire opening, so that the fire can further spread through the opening and smoke And the spread of toxic gases.

Hereinafter, the present invention will be described with reference to the drawings.
FIG. 1 is an overall view of a fireproof plugging composite material, FIG. 2 is a sectional view thereof, and the fireproof plugging composite material 1 includes a first refractory material layer 2, a shrinkage material layer 3, A second refractory material layer 4 is laminated.
Regarding the size of the fireproof plugging composite material, the inner diameter of the composite material is an inner diameter such that a vinyl chloride resin pipe or a resin-coated cable can be inserted therein, and the outer diameter is the diameter of the inserted vinyl chloride pipe. The diameter takes into account the thickness reflecting the amount of refractory material that can provide the necessary fire resistance. Also, the height needs to be high enough to ensure fire resistance and fire prevention.
The fireproof closure composite material is cylindrical, and a resin tube or resin-coated cable is inserted into it. The cylindrical shape is most commonly cylindrical, but its outer and inner surfaces are 6 Polygonal cylinders such as corners and octagons, ellipses, and other shapes may be used as long as they can surround the inserted resin tube or resin-coated cable.
For example, when three resin-coated cables are bundled in a triangular shape, if the cylindrical inner surface is triangular so as to correspond to the triangular shape, the first thermally expandable member layer is in close contact with the resin cable. It is desirable to ensure fire resistance in the event of a fire.

The fire-resistant material used for the first and second fire-resistant material layers is not particularly limited as long as it is a fire-resistant material. For example, silica, diatomaceous earth, sand, kaolin, talc, perlite, shirasu, Mica, glass, glass fiber, rock wool, cement, borax, alum, inorganic substances such as aluminum hydroxide, magnesium hydroxide, inorganic boron compounds, phosphorus-containing organic compounds such as phosphates, inorganic compounds, organic sulfonic acid compounds One or more arbitrary substances can be selected and used from known substances such as bromine-containing organic compounds and halogen-containing organic compounds.
Further, a resin or rubber may be contained as a binder for the material having fire resistance, and the resin may be silicone resin, polyvinyl chloride, chlorinated polyvinyl chloride, polyester, etc., and rubber may be butyl rubber, NBR, IIR, Synthetic rubber such as NR and natural rubber can be used.

The thermally expandable member used for the first and second thermally expandable member layers is foamed by heating of thermally expandable graphite, vermiculite, phosphate, boron-containing compound, nitrogen-containing organic compound or the like. A composition containing a swelling agent that expands and a resin or rubber as a binder component can be used. It is also possible to contain various inorganic compounds such as silica, calcium carbonate and talc as fillers.
The width (in the height direction of the cylinder) of the first refractory material layer may be 5 to 50 mm, the thickness may be 10 mm or less, and the heat when the first refractory material layer is a thermally expandable member layer. The content ratio of the expansible member is 10 to 50 wt%, and examples of the component that can be contained in addition to the binder component include a plasticizer and a stabilizer.

  As the shrinkable material, a heat-shrinkable resin or rubber tube or sheet or a shape memory alloy sheet can be used. As the heat-shrinkable resin or rubber tube or sheet, polyvinyl chloride stretched by blow molding is used. , EPR, silicone rubber, fluororubber resin, etc., rubber tubes and sheets, biaxially stretched polyester films, etc. In addition, a stretched net of heat-shrinkable resin or rubber, a stretched sheet with holes formed therein, a product in which stretched fibers are wound in multiple layers, and the like can be used. As the shape memory alloy, a known alloy such as titanium-nickel alloy, iron-manganese-silicon alloy, copper-zinc alloy, cobalt-nickel alloy can be selected and used. And, what is necessary when inserting a resin tube or the like into the fireproof plugging composite material is that the shrinkage material at the time of fire is such that the first fireproof material can be reliably moved in the inner diameter direction by shrinkage. Is to generate. Therefore, the thickness of the shrinkable material is 0.1 to 10 mm, and the width is cut to an appropriate length as necessary.

Further, as shown in FIG. 3, the first refractory material layer may have a V-shaped or U-shaped groove 5 formed from the inner surface, and the groove 5 extends to the surface of the shrink material, that is, the groove. The refractory material layer may be divided into a plurality of members by 5.
When such a groove 5 is formed, the shrinkable material layer contracts in the event of a fire, so that when the first thermally expandable member layer receives a force in the inner diameter direction, the width of the groove 5 is reduced. Thus, the first thermally expandable member layer moves toward the center of the cylinder.
Of course, the groove 5 is not necessarily provided, and the groove may not be provided when the first refractory material layer is flexible enough to move to the inside by the contraction force of the contraction material.

  When the first and second thermally expandable member layers are employed as the first and second refractory material layers, respectively, the above effects can be achieved by the expansion of these thermally expandable member layers at the time of a fire. It is necessary to select these materials according to the expansion ratio and the expansion start temperature so that the expanded member can fill the volume reduction part of the resin tube or the resin-coated cable.

In some cases, T ₁ the expansion starting temperature of the first thermal expansion member _layer, the shrinkage starting temperature of the shrinkable material layer T _2, the expansion starting temperature of said second heat expandable member layer T ₃ and T ₂ ≦ T ₁ and T ₂ ≦ T ₃ on the assumption that these temperatures are higher than the softening temperature of the resin tube. The reason for this is that the heat-shrinkable material first shrinks in order to move the first thermally expandable member layer in the inner diameter direction after the resin of the previously inserted resin tube or resin-coated cable is softened. Is necessary, or in some cases, the pressing force generated by expanding the second thermally expandable member layer to move the first thermally expandable member layer in the inner diameter direction and the contraction force of the heat shrinkable material. Depending on what can be used.

  In order to bias the force received by the first thermally expansible member layer of the fireproof plugging composite material of the present invention from the shrinkable material under the above temperature condition, the expansion of the second thermally expansible member layer is utilized. You may do it.

  Furthermore, the present invention comprises inserting the above-mentioned fireproof closure composite material into a resin pipe pipe joint, a resin pipe sleeve or a resin-coated cable sleeve to be inserted into an opening provided on a floor, ceiling or wall of a building, It may be a resin pipe pipe joint or a resin pipe sleeve in which the resin pipe or resin-coated cable is inserted into the fireproof closure composite material. Specifically, the joint end into which the resin pipe of the resin pipe joint is inserted. By inserting and installing a fire-resistant plugging composite material on the inner surface of the pipe joint, the joint end after installation on the building is connected to the non-flammable material part of the pipe joint, The material part, the resin tube or the resin-coated cable are in a state of overlapping in order.

In addition, it has a shape that covers the cylindrical shape of the fireproof plugging composite material, and an opening for passing a resin tube or resin-coated cable is provided to correspond to the hole of the cylindrical fireproof plugging composite material. It is also possible to use a fireproof blocking composite built-in fire spread prevention device. This fire-blocking composite built-in fire prevention device has an outer layer made of a fire-resistant material such as metal, wraps the upper and lower surfaces and peripheral surface of the fire-blocking composite material, and corresponds to the hole of the cylindrical fire-proof plug composite material The fireproof plugging composite material is placed inside the fireproof plugging composite material, the upper and lower surfaces, the outer peripheral surface, and the inner surface of the outer layer of the fireproof plugging composite built-in fire prevention device. A space may be provided between the two and a heat insulating material layer may be provided in the space.
Since the heat insulating material layer particularly has an action of delaying the temperature rise of the first and second thermally expandable member layers and the shrinkable material layer, the selection of the expansion start temperature of the first and second thermally expandable materials as described above. It is possible to adjust the expansion start timing of the first and second thermally expansible materials and the contraction timing of the shrinkable material by matching the shrinkage temperature of the shrinkable material. According to the result of such adjustment, if the heat-shrinkable material first contracts after the softening of the resin of the resin tube or resin-coated cable and then the first and second heat-expandable materials expand, the resin tube or resin The first thermally expandable material can expand where the covered cable was, and the second thermally expandable material can expand to fill the space created by the movement of the first thermally expandable material. It becomes.
As the heat insulating material, known heat insulating materials such as glass fiber, rock wool, silica glass, and ceramic fiber can be selected and used.
