Description

  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.

  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.

  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.

  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.

  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.

  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).

  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.

  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.

  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).

  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).

Japanese Patent No. 2878006 JP 2006-26499 A JP 2005-179905 A

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

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.

It is a schematic perspective view which shows the other example of the fireproof coating construction method of the main structure part in the conventional fireproof building.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  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.

  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.

  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. To construct.

  After that, for the entire surface of the inner surface of the outer wall 9 constructed by the respective corner members 16 and the respective panels 4 except for the portions previously covered with the sheet-like fireproof covering material 15 of the respective corner members 16, The fireproof coating material 17 for spraying containing rock wool or the like is sprayed.

  More specifically, in the step of attaching the sheet-like fireproof covering material 14 to each pillar member 1, as shown in FIG. 2, the pillar members 1 such as H-shaped steels are erected at positions corresponding to the four corners of the mechanical multistory parking lot. 2, which are attached to each column member 1 in a later step in the state of being made to interfere with the beam member 18 and the trunk member 2 as shown by a two-dot chain line in FIG. 2, and the trunk member 2 is attached to each column. A sheet-like (felt-like) fireproof covering material 14 in which a portion that interferes with an installation location of a bracket (not shown) for attaching to the member 1 is wound around and attached to each column member 1 over the entire circumference. To.

  For example, as shown in FIG. 2, the refractory coating material 14 is wound around the corresponding pillar member 1 from the center portion of the flange 1a of one of the pillar members 1 (inward of the frame structure 3 in FIG. 2). Winding in parallel to the flange surface, bending at the end of the one flange 1a, then winding in parallel to the web of the column member 1, then bending at the end of the other flange 1b, Is then rolled in parallel to the surface of the flange 1b, then bent at the end of the other flange 1b and advanced in parallel to the web of the column member 1, and then bent at the end of the one flange 1a. The refractory coating material 14 is wound up to the winding start end position, and the wrapping state of the refractory coating material 14 around the column member 1 becomes a square shape in plan view as shown in FIG. Thus, the fireproof covering 14 is a pillar It is so as to prevent the fall off from the timber 1. The fireproof covering 14 is fixed to the column member 1 by an adhesive, a so-called pin welding method using a number of well-known fixing pins, a so-called wire netting method using a PVC-coated turtle shell wire net, or the like. It is.

  As described above, when the wrapping of the fireproof coating material 14 on all of the pillar members 1 erected at the four corners of the mechanical multilevel parking lot is completed, next, as shown by the two-dot chain line in FIG. The beam members 18 are attached between the column members 1 to form the frame structure 3, and the trunk member 2 is stretched in multiple stages via brackets (not shown) outside the adjacent column members 1. And attach. In addition, the said trunk edge member 2 is the length which does not interfere with the sheet-like fireproof coating | covering material 15 of the corner material 16 inner surface arrange | positioned in the location corresponding to each corner part 6 of the building of a mechanical multistory parking lot in a later process. It shall be set.

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.

  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.

  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.

  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.

  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, and the panel 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.

  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.

  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. .

  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.

  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.

  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.

  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.

  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.

  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.

  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. Further, from the viewpoint of facilitating the attachment of the sheet-like fire-resistant coating material 15 to the inner surface of the corner material 16, it is disposed adjacent to both ends of the corner material 16 as described above. It is desirable to provide a female engaging portion 16a for receiving the male engaging portion 4a provided at the end of the panel 4 as an outer wall member from the inside (side close to the frame structure 3). Any engagement portion other than the female engagement portion 16a shown in the figure may be provided as long as it can be connected to the panel 4 by being engaged with the end portion of the adjacent panel 4. May be. In addition, as the engaging portions provided at both end portions of the corner member 16 and the corresponding engaging portions provided at the end portions of the adjacent panels 4 are engaged, When the engaging portion is arranged on the inner side (side closer to the frame structure 3) than the engaging portion of the corner member 16, the inner surface of the corner member 16 is preliminarily formed before the outer wall 9 is constructed. The sheet-like (felt-like) fireproof covering material 15 to be pasted may be pasted only at a position excluding the engaging portions at both end portions of the corner material 16. Even in this case, after the outer wall 9 is constructed, the fire-resistant coating material 17 for spraying is applied to the inner surface of the outer wall 9, so that the sheet-shaped fire-resistant coating adhered to the inner surface of the corner material 16 is applied. A fireproof coating composed of the material 15 and the sprayed fireproof coating material 17 that has been sprayed can be provided so as to cover the entire inner surface of the outer wall 9.
