Example 1
A fireproof member 110 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. 1A and 1B are perspective views from one end side and the other end side of the refractory member 110 of the present embodiment. 2A to 2C are a front view, a rear view, and a side view of the refractory member 110, respectively. 3A and 3B are an AA cross-sectional view and a BB cross-sectional view of the refractory member 110, respectively.

  The refractory member 110 of this embodiment is integrally formed of a thermally expanded material that can maintain its own shape. More specifically, the heat-expandable material is a heat-expandable rubber, and when this heat-expandable rubber is exposed to high heat (for example, 300 ° C. or higher), an expandable material whose volume expands more than twice that before heating ( Rubber obtained by mixing (expanded graphite) and molding into a predetermined shape (after the molding process) is subjected to a vulcanization process. The vulcanization step is a step of applying heat to the rubber that has undergone the molding step to cause a vulcanization (crosslinking) reaction or an adhesion reaction to obtain a product having rubber elasticity. The refractory member 110 is maintained in a cylindrical shape (shape) by the thermally expandable rubber itself.

  As shown in FIGS. 1 and 2, the refractory member 110 has a refractory member main body 111 extending from one end to the other end, and a filling portion having a bottom portion where the putty member 120 is filled on the wall front side (one end side) of the refractory member main body 111. A region 117 and a putty support 118 that protrudes from the wall surface side end surface of the refractory member main body 111 along the outer peripheral edge 117a of the filling region 117 (bottom portion) to the wall surface. Note that the “wall surface side” in the present embodiment means at least a position closer to one end (wall surface) than the center of the cylindrical portion 112 in the axial direction. The refractory member main body 111 and the tubular portion 112 formed in a hollow cylindrical shape disposed in the wall hole H of the wall material W, and projecting integrally outward from one end side of the tubular portion 112. It consists of a plate-like flange portion 114.

  As shown in FIG. 2C, the cylindrical portion 112 has a uniform diameter along the axial direction and extends linearly from one end to the other end. An insertion portion 113 into which the wiring / pipe material P can be inserted is defined in a hollow space inside the inner peripheral surface 112 a of the hollow cylindrical portion 112. On the other hand, the outer shape (contour) of the cylindrical portion 112 is defined by the outer peripheral surface 112b. That is, the thick part (thermally expansible material) between the inner peripheral surface 112a and the outer peripheral surface 112b of the cylindrical part 111 is arrange | positioned between the inner wall of the wall hole H and the outer surface of the wiring and piping material P. The outer diameter of the outer peripheral surface 112b is substantially the same (slightly smaller) as the diameter of the wall hole H, and the shape of the outer peripheral surface 112b (circular) and the shape of the wall hole H (circular) are approximately It is the same.

  The cylindrical portion 112 of the refractory member main body 111 has a cylindrical wall having a predetermined thickness between the inner peripheral surface 112a and the outer peripheral surface 112b along the radial direction. The refractory member main body 111 is heated by heat generated by a fire or the like, expands in the inner diameter direction of the cylindrical portion 112 and closes the insertion portion 113 (that is, fills the inner space of the inner peripheral surface 112a). It is preferable to have. In addition, when the cylindrical portion 112 of the refractory member main body 111 is heated and expanded from the inner peripheral surface 112a side, the thickness that maintains the shape of the outer peripheral surface 112b side of the cylindrical portion 112 is secured on the outer peripheral surface side. Preferably it is. In other words, the thickness of the cylindrical portion 112 is set such that when the inner peripheral surface 112a side is heated, the heat does not affect the outer peripheral surface 112b side from the inner peripheral surface 112a of the cylindrical portion 112. It is preferable. In the present embodiment, the thickness of the cylindrical wall of the cylindrical portion 112 is set to be thicker than the value of the ratio of the expansion coefficient of the thermally expandable rubber to the inner diameter of the inner peripheral surface 112a. Moreover, the thickness of the cylindrical wall of the cylindrical part 112 is constant along the circumferential direction. In the present embodiment, the thickness of the cylindrical wall of the cylindrical portion 112 is about 20 mm. According to the preferred embodiment, when the refractory member main body 111 is heated from the inner peripheral surface 112a side by heating the cable core wire (as shown in the prior art document 1), the optimum thermal expansion to the inside of the insertion portion 113 is achieved. Is possible. However, since the present invention is not intended only for such heating from the inner peripheral surface 112a, the shape and size of the refractory member of the present invention is not limited to this embodiment.

  The flange portion 114 is formed in a thin wall shape (in this embodiment, about 2 mm thick) over the entire circumferential direction of the refractory member main body 111 so as to extend in the radial direction from the outer peripheral edge of one end of the cylindrical portion 112. As shown in FIGS. 2 (a) and 2 (b), the outer edge that defines the contour of the flange portion 114 has a circular shape, and its diameter is larger than the diameter of the wall hole H. That is, the back surface of the flange portion 114 can abut against the peripheral wall surface of the wall hole H.

  Furthermore, a closing portion 115 for closing the insertion portion 113 on one end side in the axial direction is formed at the approximate center of one end surface (flange portion 114) of the fireproof member main body 111. On the other hand, the other end surface of the refractory member main body 111 is opened. As shown in FIGS. 3A and 3B, the closing portion 115 is formed in a thin shape like the flange portion 114, and closes one end of the refractory member main body 111 (or the insertion portion 113). The closing portion 115 is divided into a plurality of cuts passing through the center thereof. That is, the closing portion 115 is formed with a plurality of tongue pieces 115a that extend radially inward (center side) from the inner peripheral surface 112a at one end of the cylindrical portion 112. Each tongue piece 115a can be elastically deformed along the axial direction with the base end as a fulcrum (like the phantom lines in FIGS. 3A and 3B). By elastically deforming the tongue piece 115a, the closing portion 115 is deformed so as to be able to pass through the wiring / pipe material P so as to open the end face of the refractory member main body 111. In the closing portion 115, the tongue piece 115a is elastically restored after the wiring / pipe material P is inserted, so that each tongue piece 115a comes into close contact with the outer surface of the wiring / pipe material P and closes the end face again. .

  Further, the fireproof member main body 111 is formed with a slit portion 116 that extends over the entire axial direction of the tubular portion 112 and extends in a direction (radial direction) orthogonal to the axial direction. And the slit part 116 is connected so that the inner peripheral surface 112a, the outer peripheral surface 112b, and the flange part 114 outer periphery of the fireproof member main body 111 may be connected. By elastically deforming the refractory member main body 111, the slit portion 116 can be opened and the insertion portion 113 can be opened. That is, the wiring / piping material P can be inserted into the insertion portion 113 from the radial direction via the slit portion 116. The slit 116 is one of a plurality of cuts for forming the tongue piece 115a, and is used for forming the tongue piece 115a.

  Further, in the refractory member 110, a region where the putty member 120 is filled on one end surface on the wall surface side of the refractory member main body 111 is defined as a filling region 117. The bottom of the filling region 117 is a surface on which the putty member 120 is placed, and is not limited to the shape of the present embodiment, and is arbitrarily set as necessary. That is, the “filling region” is a region filled with a putty member for the purpose of sealing a fine gap of the refractory member or reinforcing a thin portion of the refractory member in terms of fire resistance.

  Then, the putty member 120 is filled in the filling region 117 so as to seal a fine gap on one end surface of the refractory member 110. More specifically, the putty member 120 is directly placed on the bottom which is the outer surface of the filling region 117. The putty member 120 is a clay-like heat-expandable heat-resistant sealing material. When the heat-expandable rubber is exposed to high heat (for example, 300 ° C. or higher), the volume of the expandable material expands more than twice that before heating ( (Expanded graphite) or the like is mixed with non-added rubber. However, the putty member of the present invention is not limited to this, and may be non-thermally expandable as long as it is at least heat resistant and can seal a fine gap.

  As shown in FIGS. 2A and 2C, the filling region 117 is bordered by an outer peripheral edge (outline) 117a having a keyhole shape. The filling region 117 is connected to the circular filling region 117b extending on the thin portion (closing portion 115) of the end surface of the cylindrical portion 112, and the slit portion 116 of the flange portion 114 is connected to the circular filling region 117b. It is combined with a rectangular filling region 117c extending upward.

  The putty member 120 filled in the circular filling region 117b fills a gap generated between the outer periphery of the wiring / pipe material P and the refractory member main body 111, fills a gap between the sections 115a of the closing portion 115, and The refractory member 110 thin portion (closed portion 115) is reinforced in terms of fire resistance. In other words, the putty member 120 is arranged mainly for the purpose of filling a fine gap by the fireproof member 110 and / or to supplement the fireproof performance, and the putty member 120 itself thermally expands radially inwardly to the wiring. -It is not arranged for the purpose of crushing the piping material P. That is, the putty member 120 of the present embodiment is clearly distinguished from the putty member 321 filled for the purpose of crushing the wiring / pipe material P in the insertion portion 313 as will be described later with reference to FIG. Can be done.

In the present embodiment, a part of the bottom of the filling region 117 (circular filling region 117b) is defined on the outer surface on the wall front side of the closing portion 115. In the present embodiment, the diameter or area of the filling region 117 (circular filling region 117b) in the front view is substantially the same as the diameter or area of the insertion portion 113, or larger than the diameter or area of the insertion portion 113. Is preferred. This is because the entire portion having a low fire resistance such as the thin wall portion on the wall surface side of the insertion portion 113 can be covered with the putty member 120 and effectively reinforced.

  On the other hand, the putty member 120 filled in the rectangular filling region 117c fills the gap on the cylindrical wall 112 and the flange portion 114 generated by the slit portion 116 (outside the closing portion 115). That is, in this embodiment, a part of the bottom of the filling region 117 (rectangular filling region 117c) is defined as a part of the outer surface on the wall surface side of the flange portion 114.

  And the putty support part 118 for supporting the putty member 120 with which the filling area | region 117 was filled is formed in the outer side (radial direction) of the filling area | region 117 along the outer periphery 117a. As shown in FIG. 2A, the putty support portion 118 extends with a substantially uniform width over the entire outer peripheral edge 117 a and surrounds the filling region 117. More specifically, the frame-like putty support portion 118 surrounds the circular filling region 117b and the rectangular filling region 117c except for the boundary between the circular filling region 117b and the rectangular filling region 117c. A portion of the putty support portion 118 extends in a direction intersecting the slit portion 116 at the periphery of the flange portion 114 so as to border the rectangular filling region 117c, and sandwiches the slit portion 116. It extends in parallel.

  Further, as shown in FIGS. 3A and 3B, the putty support 118 protrudes from the bottom of the outer peripheral edge 117a of the filling region 117 to the wall surface side with a predetermined height h from the wall surface side end surface of the refractory member main body 111. ing. The protrusion height h of the putty support portion 118 is a distance from the base end of the putty support portion 118 (the outer peripheral edge 117a of the filling region 117) to the end surface thereof. The protrusion height h is preferably equal to or higher than the required filling height of the putty member 120. The required filling height of the putty member 120 is defined by various conditions such as required fire resistance performance and dimensions of the fire resistance member. For example, in the refractory member 110 of the present embodiment, the putty filling with clay of 3 mm or more is required by definition. In such a case, the protrusion height h of the putty support portion 118 is preferably 3 mm or more so as to prevent the putty member 120 from protruding in the axial direction from the putty support portion 118.

  Then, with reference to FIG.4 and FIG.5, the fire prevention division wall structure 10 of one Embodiment of this invention is demonstrated in detail. FIG. 4 is a perspective view of the fire prevention compartment wall structure 10 in which the fireproof member 110 of the present embodiment is installed in the wall hole H of the wall material W for the fire prevention compartment. 5 (a) and 5 (b) are a front view and a CC cross-sectional view of the fire protection compartment wall structure 10. FIG.

  The wall material W for the fire prevention compartment of the present embodiment is a hollow fireproof wall erected vertically. The wall material W is made of gypsum board, and is constructed by being fixed to a plurality of standing pillars (not shown). By constructing these two wall materials W on the front and back with the interposition between them, a hollow space (wall back space) is formed between the wall materials W. In order to penetrate the hollow fireproof wall, each wall member W is provided with a wall hole H having a diameter through which a wiring / pipe material P having a predetermined thickness can be penetrated by a hole saw or the like. The wall hole H has a perfect circular shape, and the inner diameter thereof is formed to be substantially the same (slightly larger) as the outer diameter of the cylindrical portion 112 of the fireproof member 110. And the wall surface space of one wall material W and the wall surface space of the other wall material W are connected by the two wall holes H. That is, the fire prevention partition wall structure 10 can penetrate the wiring / pipe material P through both wall holes H and the hollow space. In addition, the wall material of this invention is a concept also including structures, such as a ceiling and floor for fire prevention compartments, and is not limited to the form of this embodiment. Further, the wiring / pipe material P of the present embodiment includes wiring (control cable, coaxial cable, optical cable, etc.) and piping material (synthetic resin flexible conduit, steel conduit, etc.) disposed in the building. However, the wiring / pipe material of the present invention is a broad concept that means various long materials, and is not limited to this. That is, the wiring / pipe material of the present invention may not have a metal core wire.

  The fire prevention compartment wall structure 10 of the present embodiment can be arranged by penetrating the wiring / pipe material P through the wall hole H, and the fire resistant member 110 is arranged in the wall hole H of the wall material W for the fire prevention compartment, The wiring / pipe material P is inserted into the insertion portion 113 of the refractory member 110, and a predetermined amount of putty member 120 is filled on the filling region 117 of the refractory member 110. In other words, the fireproof member 110 and the putty member 120 function cooperatively as a penetration part forming device for forming a penetration part for the wiring / pipe material P in the wall material W for the fire prevention compartment.

  More specifically, in the fire prevention partition wall structure 10, as shown in FIG. 5B, the hollow cylindrical tubular portion 112 of each fireproof member 110 is inserted into the wall hole H of the wall material W. Two fire-resistant members 110 are respectively installed in the wall holes H of the pair of wall members W, and each wall member has a penetrating portion communicated so as to be able to penetrate the wiring / pipe member P through the two wall members W. W is formed. As described above, since the outer diameter of the cylindrical portion 112 of the refractory member main body 111 is substantially equal to the inner diameter of the wall hole H, the outer peripheral surface 112b of the cylindrical portion 112 and the inner peripheral surface of the wall hole H are almost in close contact. Yes. Moreover, one end of the refractory member 110 is disposed on the wall front side, and the other end faces the wall back side. The rear surface of the flange portion 114 is in contact with the wall surface of the peripheral edge of the wall hole H. The other end surfaces of the pair of refractory members 110 on the wall side are opposed to each other at positions close to each other in the wall space.

  A single wiring / pipe material P is disposed through substantially the center of both wall holes H so as to penetrate the two wall materials W. The wiring / pipe material P penetrates the insertion portion 113 of the refractory member main body 111 of the refractory member 110 in the axial direction. And each tongue piece 115a of the closing part 115 bends in the other end side in the insertion part 113, and each tongue piece 115a is closely_contact | adhered to the outer surface of the wiring and piping material P by the elastic return force. That is, the blocking portion 115 closes the space between the outer surface of the wiring / pipe material P and the inner peripheral surface 112b of the main body 110 so that the insertion portion 113 in the fireproof member 110 is not exposed on the wall surface.

  Further, as shown in FIGS. 5A and 5B, a thermally expandable putty member 120 is filled on a filling region 117 defined on one end face of the refractory member 110. The putty member 120 seals the gap between the closing portion 115 and the wiring / piping material P, the gap between the tongue pieces 115 a of the closing portion 115, and the entire slit portion 116 in the filling region 117.

  As shown in FIG. 5A, in the front view, the putty member 120 fills both the circular filling region 117b and the rectangular filling region 117c without any gap, and does not protrude from the outer peripheral edge 117a of the filling region 117. It is entirely surrounded by the portion 118. As shown in FIG. 5B, the putty member 120 has a substantially flat outer surface on the wall surface side so as not to exceed the protruding height h of the putty support portion 118. That is, the putty member 120 is leveled by a filling jig (for example, a spatula) according to the protruding height h of the putty support portion 118. A putty support portion 118 extends below the outer peripheral edge 117 a of the filling region 117. That is, the putty support portion 118 supports the putty member 120 on the filling region 117 from the lower side in the vertical direction, and reduces the possibility that the putty member 120 falls due to gravity. Further, since the putty support portion 118 extends over the entire outer peripheral edge 117a, the putty member 120 is filled so as not to protrude outside the filling region 117. In addition, in the present fire prevention partition wall structure 10, the slit 116 is arranged so that the tip of the slit 116 faces the 9 o'clock direction. However, since the putty support part 118 surrounds the entire filling region 117, Even if is changed, the same dripping prevention effect and protrusion prevention effect can be stably exhibited.

  Moreover, in the fire prevention partition wall structure 10 of this embodiment, in order to make a fire prevention function more reliable, this putty member 120 is stacked so that the filling height is about 3 mm. In this embodiment, the protrusion height h of the putty member 120 is set to about 3 mm (that is, the required filling height or more), which is the same as the minimum protruding amount, so that the putty member 120 exhibits the desired fire resistance. Is prevented from projecting in the axial direction (the wall surface side) beyond the putty support portion 118.

In the present embodiment, the putty member 120 is filled in the filling region 117 covering the closing portion 115 and the slit portion 116 in a state where the insertion portion 113 is hollow, but the present invention is not limited to this form. For example, although not shown, for the installation structure in which a putty member is separately filled in the insertion portion 113 inside the closing portion 115, the end surface on the wall front side of the fireproof member 110 is used for the purpose of filling a small gap in the fireproof member 110. The putty member 120 may be filled into the predetermined filling region 117 afterwards. In the fire prevention compartment wall structure constructed in this way, a larger amount of putty members are used and fine gaps are further closed by the putty members 120, so that higher fire prevention performance is exhibited.

  FIG. 6 is a schematic diagram of a fire prevention compartment wall structure 10 ′ in which the wall hole H is closed when a fire occurs. This fire prevention partition wall structure 10 ′ assumes that a fire has occurred only in the space on one side (left side in FIG. 6) and the refractory member 110 on one side is heated from the fire space. As shown in FIG. 6, when the fireproof member 110 and the putty member 120 are thermally expanded, flame, smoke, and toxic gas generated on one side flow into the space on the other side (right side in FIG. 6) through the wall hole H. To be prevented.

  More specifically, as shown in FIG. 6, in the fire protection wall structure 10 ′, a part of the covering material of the wiring / piping material P burns on the fire space side, and the metal core P ′ is partially exposed. Yes. In the fire-resistant member 110 on one side, the inner peripheral surface 112a of the fire-resistant member main body 111 expands radially inward to surround the partially exposed outer surface of the core wire P 'in a close contact state. In other words, the initial gap between the outer surface of the wiring / piping material P and the inner peripheral surface 112a of the refractory member 110 is partially filled with the thermally expandable material and hermetically closed. Further, the flange portion 114, the putty support portion 118, and the putty member 120 are heated and thermally expanded to the wall front side. As the putty member 120 expands, the putty support portion 118 expands in the axial (wall surface) direction, so that the thermally expanded putty member 120 is supported by the putty support portion 118 without dropping. And in the fireproof member 110 of the other side, the other end of the fireproof member main body 111 is heated and thermally expanded. However, since heat is not sufficiently transmitted to the wall surface on the other side, one end surface (flange portion 114, putty support portion 118) of the fire-resistant member 110 on the other side remains in its original shape without being thermally deformed.

  It should be noted that the fire prevention compartment wall structures 10 and 10 'described here are merely examples, and the fire prevention compartment wall structure of the present invention is not limited thereto. For example, the wall material may not be a hollow fireproof wall but may be a single concrete wall that does not include a hollow space (or wall space). In addition, the form of expansion of the refractory member always changes depending on the fire environment and the like. Therefore, the fire prevention compartment wall structure 10 ′ described here is merely an example of an expanded form, and does not limit the present invention.

  Next, with reference to FIGS. 7 and 8, a method for constructing the fire-proof compartment wall structure 10 by installing the fire-resistant member 110 and the putty member 120 of the present embodiment on the wall material W will be described. 7 and 8 show that one refractory member 110 is installed for one wall material W for convenience of explanation.

  First, a wall hole H having a predetermined size is drilled in the wall material W with a horuseau or the like. Next, the wiring / pipe material P is disposed through the wall hole H. Next, as shown in FIG. 7, the fireproof member 110 is elastically deformed to open the slit portion 116, and the wiring / pipe material P is inserted into the insertion portion 113 through the opened slit portion 116. Then, by elastically restoring the refractory member 110, the slit portion 116 is closed and the wiring / pipe material P can be held in the insertion portion 113.

  Next, as shown in FIG. 8, the refractory member 110 is slid along the wiring / pipe material P so that the cylindrical portion 112 of the refractory member main body 111 is disposed in the wall hole H and the flange portion 114 is brought into contact with the wall surface. . In this state, the putty member 120 is filled into the filling region 117 of the refractory member 110. The putty member 120 is an approximately rectangular parallelepiped clay-like substance in the initial form, and can be deformed into a desired shape by applying a force with a hand or the like. That is, the putty member 120 is placed on the end surface of the fireproof member main body 111 so as to be deformed, and the putty member 120 is filled on the desired filling region 117 surrounded by the putty support portion 118.

  Then, the portion raised from the putty support portion 118 to the wall surface side (or protruding to the wall surface) is leveled with a jig such as a spatula. At this time, since the putty support portion 118 surrounds the entire filling region 117, the spatula was raised by running the spatula along the end surface (in the protruding direction) of the putty support portion 118 over the entire filling region 117. Unnecessary portions of the putty member 120 can be easily scraped off. Further, since the protruding height h of the putty support portion 118 is higher than the required filling height of the putty member 120, the putty member 120 having the required filling height can be transferred to the filling region 117 simply by leveling the surface with a spatula. Easy to fill. Thus, the fireproof member 110 is installed on the wall material W in a state of being sealed with the putty member 120. And if the same operation | work is implemented also with respect to the other wall material W, the fire prevention division wall structure 10 of FIG. 5 will be constructed | assembled.

  Note that the method described here is merely an example, and those skilled in the art can change the order of the steps or omit unnecessary steps depending on the situation. For example, the fire-resistant member 110 is first installed in the wall hole H, and the wiring / pipe material P is inserted into the insertion portion 113 from the longitudinal direction of the wall / pipe material P through the opening of one end or the other end thereof. Can be included.

  Hereinafter, the operation and effect of the fireproof member 110 (or the fireproof partition wall structure 10) according to an embodiment of the present invention will be described.

  In the fireproof member 110 (or the fire prevention partition wall structure 10) of the present embodiment, the putty member 120 filled in the filling region 117 is supported by the putty support portion 118 that protrudes from the outer peripheral edge 117a of the filling region 117 to the front side of the wall. In particular, since the putty support portion 118 is provided below the outer peripheral edge 117a of the filling region 117, the putty member 120 in which the putty support portion 118 is filled in the filling region 117 when the fireproof member 110 is installed in the wall hole H. Is supported from below in the vertical direction. Further, since the protruding height h of the putty support portion 118 is substantially the same as the required filling height of the putty member 120, the putty member 120 is filled in an amount (height) necessary to ensure the desired fire resistance. Even when the region 117 is filled, the putty member 120 does not protrude from the putty support portion 118 to the wall surface side. Furthermore, by filling the putty member 120 in accordance with the protrusion height h of the putty support portion 118, it is possible to prevent the putty member 120 from being excessively filled. That is, according to the present embodiment, the putty member 118 protrudes laterally from the filling region 117 in order to surround the putty member 120 and prevent the putty member 118 from projecting to the wall surface more than the putty member 118. The risk of shifting, shifting or dripping can be greatly reduced. Therefore, in the fireproof member 110 and the fireproof partition wall structure 10 of the present embodiment, the putty support portion 118 can more securely retain the putty member 120 in the predetermined filling region 117, thereby maintaining desired fireproof performance. is there. Furthermore, by preventing the putty member 120 from dripping or shifting, as a result, it is possible to keep the appearance of the wall material W and the floor surface around the fireproof member 110 (wall hole H) so as not to become dirty.

  In the refractory member 110 of this embodiment, the slit 116 extends from the substantially center position (closed portion 115) to the outer edge of the flange portion 114 over the circular filling region 117b and the rectangular filling region 117c. The putty support portion 118 extends in the direction intersecting the slit portion 116 at the periphery of the flange portion 114, and extends parallel to the slit portion 116 so as to sandwich the slit portion 116. That is, according to the present embodiment, when the putty member 120 is filled in the filling region 117, the entire slit portion 116 is covered and sealed with the putty member 120, and deterioration in fire resistance due to the formation of the slit portion 116 can be suppressed. . Furthermore, it is possible to effectively prevent the putty member 120 that covers the slit portion 116 on the rectangular filling region 117c from protruding sideways or dripping down.

The refractory member main body 211 includes a tubular part 212, an insertion part 213, a flange part 214, a closing part 215, and a slit part 216. In the present embodiment, unlike the refractory member 110 of the first embodiment, the filling region 217 is defined as a circular region on the closing portion 215 formed at a position recessed from one end surface of the tubular portion 212. In other words, the bottom of the filling region 217 is positioned on the front side of the wall from the center in the axial direction of the cylindrical portion 212. On the outer peripheral edge 217a of the filling region 217, a putty support portion 218 is formed in an annular shape when viewed from the front. That is, the putty support portion 218 has a predetermined height h (see FIG. 10 (FIG. 10 ()) from the filling surface 217 retracted from the end surface of the refractory member main body 211 to the wall back (other end) side than the wall front side end surface of the refractory member main body 211. It protrudes in b). In this embodiment, the putty member 220 may be filled on the slit portion 216 extending at the flange portion 214, but this location is not defined as the “filling region” of the present invention.

As shown in FIG. 10A, in the front view, the putty member 220 is filled in the circular filling region 217 without a gap, and is not entirely protruded from the outer peripheral edge 217a of the filling region 217 by the putty support portion 218. Besieged. 10B, the putty member 220 has a substantially flat outer surface on the wall surface side so as not to exceed the protruding height h of the putty support portion 218. A putty support portion 218 extends below the outer peripheral edge 217 a of the filling region 217. That is, the putty support portion 218 supports the putty member 220 on the filling region 217 from the lower side in the vertical direction. Therefore, in the present fire prevention wall structure 20, as with the fire protection wall structure 10, the putty support portion 218 supports the putty member 220, thereby greatly reducing the possibility that the putty member 220 will drop due to gravity. Yes. In this embodiment, as compared with the first embodiment, since the filling region 217 is in a deep position, the protrusion height h can be relatively increased, and more putty members 220 can be filled. Is possible.

At a part of the outer peripheral edge 317a of the rectangular filling region 317, a putty support portion 318 is formed so as to protrude in a rectangular frame shape opened upward in a front view. That is, the filling region 317 is formed on the flange portion 314 along the slit portion 316 at the end face of the fireproof member main body 311. In addition, one end surface of the refractory member main body 311 is open, and the other end surface is closed by a closing portion 315.

That is, the tip of the slit portion 316 faces the 6 o'clock direction, and the putty support portion 318 that intersects the slit portion 316 supports the putty member 320 from the lower side in the vertical direction. On the other hand, even when the tip of the slit portion 316 is oriented in the direction of 3 o'clock or 9 o'clock, the putty support portion 318 extending in parallel to the slit portion 316 supports the putty member 320 from the lower side in the vertical direction. That is, in this embodiment, as long as the open portion of the putty support portion 318 does not face downward, the putty support portion 318 functions to support the putty member 320 from the lower side in the vertical direction. Therefore, in this fire protection partition wall structure 30, the putty support portion 318 is disposed at least below the filling region 317 to support the putty member 320, thereby greatly reducing the possibility that the putty member 320 will drop due to gravity. Yes. Furthermore, since the slit part 316 is covered with the putty member 320 and sealed, a reduction in fire resistance due to the formation of the slit part 316 is suppressed.

(Modification)
Although the embodiment of the present invention has been described, the present invention is not limited to the first to fourth embodiments. For example, in the above-described embodiment, the outer peripheral shapes of the wall hole and the end surface of the refractory member main body are all round, but these may be other shapes such as an ellipse or a polygon, and may be different from each other. And in the fire prevention division wall structure of the said embodiment (Examples 1-3), although the penetration part formation apparatus was installed in both wall material W of a hollow fireproof wall, this invention is not limited to this. In other words, the fireproof partition wall structure of the present invention includes a structure in which the penetration forming device is installed only on one wall material W of the hollow fireproof wall.
