  Here, from the viewpoint of industrialization of the building, a construction procedure may be considered in which a column or wall panel is attached to a beam material at a factory, and the beam material is transported to a construction site in that state. Thereby, when constructing the standing wall portion, the work burden on the construction site can be reduced.

  By the way, in the structure which the standing wall part does not extend along the peripheral part of the overhanging part but extends along the peripheral part of the building body, the standing wall part is in addition to the beam material to the column. It will be installed. However, the work of installing the standing wall part on the beam and the work of installing the standing wall part on the column are performed in one process due to the convenience of the construction procedure when building the building. It cannot be performed, and it is assumed that it must be performed at different timing in another process. For example, while the installation work of the standing wall part with respect to the beam material is performed at a factory, the installation work of the standing wall part with respect to the pillar may be inevitably performed at a construction site. Therefore, there is room for improvement regarding the industrialization of the standing wall.

  This invention is made | formed in view of the said situation, and it aims at reducing the work burden in a construction site suitably regarding the construction of the wall part which stood outdoors.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, for easy understanding, the corresponding configuration in the embodiment of the invention is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.

  The wall structure of the building of the first invention extends along the peripheral part of the building frame having a column (column 21) and an upper beam (ceiling beam 22) connected to the upper end of the column, It is applied to a building provided with a standing wall portion (parapet 18) standing upwards outdoors, and the standing wall portion includes a pair of standing wall materials (parapet face materials 62, 63) facing each other, and A standing wall base (parapet base 61) provided between a pair of standing wall materials and fixed to the building frame, wherein the standing wall base is fixed to the upper beam. And a wall structure of a building having a support frame portion (adjacent frame portions 65B and 65C) supporting each of the pair of standing wall surfaces, wherein the pillars are interposed between the pair of standing wall materials. On top of the pillar fixed to the pillar A frame part (column top frame part 65A) is provided side by side on the support frame part along the peripheral part of the building frame, and the column frame part is fixed to the upper beam. By being connected to the support frame portion, the standing wall base is constituted together with the support frame portion.

  According to the first invention, in the configuration in which the standing wall portion straddles the boundary portion between the column and the upper beam in the wall width direction, the standing wall portion is connected to the column and the upper via the column upper frame portion and the support frame portion. It is fixed individually for each beam. For this reason, even if the work of installing the standing wall part with respect to the beam material and the work of installing the standing wall part with respect to the column must be performed at different timings in different processes, A part can be properly attached to only one of the column and the upper beam. Therefore, while the installation work of the standing wall part for the beam material is performed at the factory, the support frame part is attached to the upper beam at the factory even when the installation work of the standing wall part for the column is unavoidable at the construction site. Thus, the standing wall portion and the upper beam that do not include the columnar frame portion can be transported to the construction site in an appropriate state. After installing the building frame at the construction site, it is possible to construct the standing wall portion by performing the minimum work of fixing the top frame portion to the pillar and connecting it to the support frame portion.

  As described above, the work burden at the construction site can be suitably reduced when industrializing the standing wall.

  In a second invention, in the first invention, the building is a unit type building constructed by combining a plurality of building units (building units 20), and in the building unit, a unit housing that forms the building housing ( The unit housing 31) includes the column and the upper beam, and the upper end portion of the column to which the column upper frame portion is fixed is connected to the building units and suspended to lift the building unit. A usable working hole (hanging hole 81) is provided in at least one of the hooks of the tool.

  In the unit type building using the building unit for the purpose of industrialization of the building, in the configuration in which the work hole is provided at the upper end of the pillar, the standing wall part is installed at the stage before the building unit is installed at the construction site. If it is installed with respect to the pillar, there is a concern that the standing wall part may become an obstacle when the building unit is installed.

  On the other hand, according to the second invention, since the column provided with the work hole is an attachment target of the columnar frame portion, the large portion of the standing wall portion excluding the peripheral portion of the columnar frame portion is large. The part can be built at the factory. Therefore, the number of work steps at the construction site can be reduced as much as possible with respect to the construction of the standing wall portion.

  In a third invention, in the second invention, the support frame part is attached to the unit housing in a factory, and the columnar frame part is installed after the building unit is installed at a construction site. The unit housing and the support frame portion are attached.

  According to the third aspect of the invention, the support frame portion of the building unit is preceded at the factory, while the columnar frame portion is retrofitted at the construction site. When connecting, it can avoid that a frame on a pillar obstructs.

  In a fourth aspect of the invention, the upper beam is stretched over the adjacent columns, and the support frame portion is disposed between the adjacent columns across the upper beam, and the outdoor side surface of the upper beam The inner wall surface material (inner parapet surface material 63) provided on the inner side of the standing wall base of the pair of standing wall surface materials is provided between the columnar frame portion and the support frame portion. In a state of being stretched, it is fixed to each of the pillar frame portion and the support frame portion.

  According to the fourth invention, since the columnar frame portion is provided, the columnar frame portion and the support frame portion are disposed at a position higher than the column even if the support frame portion is disposed between the adjacent columns. It can be arranged side by side along the inner wall surface material. Therefore, the inner wall surface material can be properly attached to both the columnar frame portion and the support frame portion.

  Here, since the support frame part is disposed on the outdoor side of the upper beam, it is easy to install the support frame part in a state of extending downward from the upper beam. In this case, in the configuration in which the standing wall portion extends upward from the outer wall portion, the support frame portion as the standing wall base also serves as the outer wall base that is the base of the outer wall portion. In order to industrialize both the outer wall portion and the outer wall portion, it is preferable to install the support frame portion at a timing (for example, a factory) for constructing the outer wall portion. On the other hand, because the columnar frame part is installed on the column and independent from the outer wall part, even when the outer wall part is constructed in the process before the installation of the columnar frame part It can suppress that the construction procedure of an outer wall part becomes complicated.

  According to a fifth invention, in any one of the first to fourth inventions, an outer wall surface material (outer parapet surface material 62) provided on the outside of the standing wall base of the pair of standing wall materials and the column top Between the frame parts, a connection base (the outer wall base 35 of the protruding corner panel 32A) that connects the support frame parts adjacent to each other with the columnar frame part interposed therebetween is provided. It is attached to the connection base among the columnar frame part and the connection base.

  According to the fifth invention, since the outer wall surface material is fixed to the support frame portion via the connection base, the outer wall surface material is installed on the outer side of the columnar frame portion before the columnar frame portion. In this case, it is possible to prevent the outer wall surface material from becoming unstable because there is no column top frame. Moreover, when installing the column top frame part in a separate process after the installation work of the support frame part, it is not necessary to perform the work of installing the outer wall surface material outside the column top frame part. The number of work steps can be reduced.

  According to a sixth invention, in the fifth invention, a plurality of the outer wall surface materials are provided side by side along the peripheral edge of the building housing, and the plurality of outer wall surface materials are vertically arranged along the pillars. The wall surface material along the pillar extending in the direction (outer wall surface material 36 of the protruding corner panel 32A) and the adjacent wall surface material adjacent to the wall surface material along the pillar (the outer wall surface material 36 of the adjacent panels 32B and 32C) are included. The adjacent wall surface material is attached to the support frame portion, and the wall surface along the pillar is attached to the connection base.

  According to the sixth invention, since the adjacent wall surface material is provided separately from the wall surface material along the pillar in accordance with the support frame portion, it is supported by the outer wall frame and the outer wall surface material possessed by the outer wall panel as a general-purpose product. A frame part and an adjacent wall surface material can be formed. In this case, unlike the structure in which the wall material as a dedicated product is attached to both the support frame and the column frame, only the wall material along the column of the wall material along the column and the adjacent wall material is manufactured as a dedicated product. Therefore, the cost burden related to the construction of the standing wall can be reduced.

  Also, in this case, the wall surface along the pillar that is separate from the adjacent wall surface material is provided on the outside of the frame on the pillar, but this wall surface material along the pillar is attached to the connection base, The wall material along the pillar can be installed without waiting for the installation of the upper frame part. In other words, the wall surface material along the pillar can be attached to the building frame at the factory, not at the construction site. Therefore, it is possible to suppress an increase in the number of work man-hours at the construction site while realizing a reduction in cost burden regarding the construction of the standing wall portion.

  In a seventh invention, in any one of the first to sixth inventions, the building frame has a lower beam (floor beam 23) connected to a lower end portion of the column, and the standing wall portion is And extending upward from the outer wall portion (outer wall portion 19) of the building, and the outer wall portion is attached to the upper beam and the lower beam in a state of being spanned between the upper beam and the lower beam. An outer wall frame (outer wall base 35) and an outer wall surface material (outer wall surface material 36) attached to the outer wall frame are provided, and the support frame portion is provided in a state of protruding upward from the outer wall portion. Of the pair of standing wall materials, an outer wall surface material (outer parapet surface material 62) provided outside the standing wall base is provided in a state of protruding upward from the outer wall portion. The outer wall surface material.

  According to the seventh invention, the support frame portion and the adjacent wall surface material are formed by an easy operation of installing the outer wall panel in which the outer wall material and the outer wall frame are integrated so as to protrude upward from the upper beam. can do. That is, the frame material and the wall surface material can be shared by the standing wall portion and the outer wall portion. For this reason, compared with the structure by which the frame material and wall surface material were separately provided by the standing wall part and the outer wall part, the work man-hour regarding manufacture of the standing wall part and outer wall part in a factory can be reduced.

  In an eighth invention according to any one of the first to seventh inventions, the upright wall portion includes a first portion (of the parapet 18) having one of the support frame portions adjacent to each other across the columnar frame portion. A first portion 18a) and a second portion (second portion 18b of the parapet 18) having the other and intersecting the first portion, and the upper frame portion of the column is A leg portion (leg portion 71) standing upright, and a first arm portion (first arm) extending from the leg portion along the first portion and connected to the support frame portion of the first portion Part 72) and a second arm part (second arm part 73) extending from the leg part along the second part and connected to the support frame part of the second part.

  According to the eighth invention, in the columnar frame portion arranged at the corner portion of the standing wall portion, the leg portion bends in the direction in which the connecting portion between the first arm portion and the second arm portion moves downward. Can be suppressed. In addition, since at least three members of the first arm portion, the second arm portion, and the leg portion are unitized as a columnar frame portion, the columnar frame is provided at a place where the structure of the corner portion of the wall portion is likely to be complicated. By using one unit called a part, two adjacent frame parts can be easily connected to one pillar.

  According to a ninth invention, in any one of the first to eighth inventions, the columnar frame part includes the first arm part and the second arm part in the first part and the second part, respectively. The support frame portion is overlaid from above, and the overlapped portion is fixed to the support frame portion, thereby being connected to the support frame portion.

  According to the ninth invention, since each arm portion of the columnar frame portion is superimposed on the support frame portion from above, when retrofitting the columnar frame portion to the already installed support frame portion, There is no need to allow the arm portion of the columnar frame portion to enter the lower side of the support frame portion. Therefore, the work of fixing the columnar frame part to the support frame part can be facilitated.

  In the building manufacturing method of the tenth invention, the building manufacturing method includes the wall structure of the second invention, wherein the support frame portion is attached to the upper beam of the unit housing in the factory.

  Next, the construction procedure of the building 10 will be described. First, the process which manufactures the building unit 20 in a factory is performed. In this process, for the building unit 20A, the outer wall panel 32 (protruding corner panel 32A, adjacent panels 32B and 32C) and the roof panel 33 are attached to the unit housing 31 at the factory. In this case, for the adjacent panels 32B and 32C, the outer wall surface material 36 is fixed to the unit housing 31 (ceiling ceiling beam 22) via the adjacent frame portions 65B and 65C, and for the protruding corner panel 32A, the outer wall surface materials 36a and 36b. Is attached to the unit housing 31 via the base horizontal member 45 and the vertical frame member 41. Here, in the building unit 20A, the upper frame portion 65A, the roof waterproof sheet 55, the base plate 66, the inner parapet face material 63, and the like are not attached, so that the upper end portion of the column 21 is exposed upward. It has become.

  Thereafter, the building unit 20 with the panels 32 and 33 attached thereto is transported from the factory to the construction site. After the building unit 20A is transported to the building site, the building unit 20A is lifted by using a heavy machine such as a crane, thereby performing a process of installing the building unit 20A on the building unit 20A of the first floor portion 14. Here, a hook hole 81 for hooking a hook or the like of a lifting tool when the building unit 20A is lifted is provided at the upper end of the column 21 of the building unit 20A. The hook hole 81 is disposed on the upper end surface of the column 21 on the side of the flat roof portion 17 from the parapet 18 in a plan view, and is covered with a roof waterproof sheet 55 from above when the roof 13 is constructed.

  If the columnar frame portion 65A is installed on the column 21, there is a concern that the columnar frame portion 65A may become a hindrance when the hooking tool is hooked in the hooking hole 81, but the columnar frame portion 65A. However, since it is not attached to the building unit 20A in the factory, the concern can be solved. The hook hole 81 corresponds to a work hole that can be used for hooking the lifting tool.

  Incidentally, when lifting the building unit 20 </ b> A, the lifting tool may be hooked in the connecting hole 34 a of the column 21. In this case, the connecting hole 34a is used as a work hole.

  After the building unit 20A is installed on the first floor portion 14, the columnar frame portion 65A is erected on the column 21, the base plate portion 74 is fixed to the upper end portion of the column 21, and the arm portions 72 and 73 are provided.

  In the building unit 20A, since the non-installation part where the adjacent frame parts 65B and 65C are not installed is provided above the pillar 21, the parapet base 61 can be constructed without including the pillar frame part 65A. . In addition, in the protruding corner panel 32A provided outside the column 21, the outer wall surface material 36 is supported by the outer wall substrate 35 (the substrate horizontal member 45) spanned between the adjacent frame portions 65B and 65C. Even if the upper frame portion 65A is not mounted on the pillar 21, it is possible to prevent the outer wall panel 32 of the protruding corner panel 32A from being deformed or damaged during the transportation of the building unit 20A. That is, the building unit 20A can be transported in an appropriate state.

  In the building unit 20 </ b> A, the outer wall panel 32 is provided in a state of projecting upward from the unit housing 31, so that separate base materials and exterior materials are used for the outer wall portion 19 and the parapet 18 on the outer peripheral side of the building 10. There is no need. Therefore, it is possible to reduce the work burden when constructing the outer wall portion 19 and the parapet 18. Moreover, since the outer wall base 35 is provided outside the column 21 in the protruding corner panel 32A, it can be avoided that the outer wall base 35 of the protruding corner panel 32A becomes an obstacle when the building unit 20A is transported. Moreover, since the outer wall base 35 exists also in the protruding corner panel 32A, it can be avoided that the outer wall panel 32 cannot be properly supported because the column top frame portion 65A is retrofitted.

  In the adjacent panels 32B and 32C, the outer wall base 35 is firmly fixed to the unit housing 31 because the outer wall base 35 is suspended over the two members of the ceiling beam 22 and the floor beam 23 of the building unit 20A. become. Here, there is a concern that the upper frame portion 65A has a low fixing strength with respect to the unit housing 31 due to being placed on one member called the column 21, but the first arm portion 72 and Since the second arm portion 73 is fixed to the ceiling beam 22 and the floor beam 23 via the outer wall base 35 (adjacent frame portions 65B and 65C) of the adjacent panels 32B and 32C, the second arm portion 73 is firmly fixed to the unit housing 31. Will be. Therefore, in the parapet 18, the inner parapet face material 63, the headboard 58 and the like can be suitably supported by the columnar frame portion 65 </ b> A.

  In the building unit 20 </ b> A, since the columnar frame portion 65 </ b> A is provided on the column 21, the inner parapet face material is caused by the adjacent frame portions 65 </ b> B and 65 </ b> C being disposed between the adjacent columns 21. Even if 63 is disposed above the column 21, the inner parapet face member 63 can be properly supported by the columnar frame portion 65A.

  In the columnar frame portion 65A, the connection portion between the first arm portion 72 and the second arm portion 73 is supported from below by the leg portion 71, so that the connection portion between the arm portions 72 and 73 (the projecting corner of the parapet 18). It can suppress that a part) bends below. In addition, since the columnar frame portion 65A is formed by unitizing the leg portion 71, the first arm portion 72, and the second arm portion 73, the column portion in the corner portion of the parapet 18 is likely to be complicated. By using one unit of the upper frame portion 65A, the two adjacent frame portions 65B and 65C can be easily connected to the single pillar 21.

  Since the columnar frame portion 65A is superimposed on the overlapping portion 79 of the adjacent frame portions 65B and 65C from above, the alignment and fixing operation of the columnar frame portion 65A with respect to the adjacent frame portions 65b and 65C can be easily performed. it can.
