Description

[Technical Field]

[0001] The present invention relates to a building construction method. [Background technology]

[0002] One technique that has been proposed for dividing a building into multiple construction sections for construction is to construct the frame sections of two above-ground structures in two construction sections, and then suspend the roof section of another above-ground structure between the two frame sections via a rail body separately installed between them, and then construct the remaining section of the other above-ground structure below the roof section (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 09-273311 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, there has been a growing need to avoid delays in construction due to wind when constructing a building. However, in the above-mentioned conventional technology, as described above, the construction of the frame parts of two above-ground structures and the laying of the roof part of another above-ground structure are carried out first, which makes the building more susceptible to the effects of wind when constructing the building, and there is a risk that it may become difficult to avoid delays in construction due to the wind. Therefore, there is room for improvement in terms of avoiding delays in construction of buildings.

[0005] The present invention has been made in view of the above, and aims to provide a building construction method that makes it possible to avoid delays in the construction of a building. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems and achieve the objectives, the building construction method described in claim 1 is a construction method for dividing a building into multiple construction sections and constructing it, and includes: a first construction process for constructing a first ground structure that constitutes the building in a first construction section; a second advance construction process for constructing a second ground structure that constitutes the building in a second construction section adjacent to the first construction section after or during the first construction process, while supporting a portion of the second ground structure that constitutes the building, including at least an exterior wall portion, on the first ground structure; and a second subsequent construction process for constructing another portion of the second ground structure after the second advance construction process, while supporting the other portion on the first ground structure.

[0007] The building construction method described in claim 2 is the building construction method described in claim 1, wherein in the second advance construction process, the portion including the outer wall portion and roof portion of the second above-ground structure is constructed.

[0008] The building construction method according to claim 3 is the building construction method according to claim 2, which further includes, after the second preceding construction step, an air conditioning adjustment step of adjusting the air conditioning in at least the second construction area.

[0009] The building construction method described in claim 4 is a building construction method described in any one of claims 1 to 3, wherein the exterior wall portion of the second ground structure is connected to the column or beam portion of the second ground structure via an exterior wall support material and a base member, and the base member comprises a support beam material and a furring strip material connecting the exterior wall support material and the support beam material, and the support beam material and the furring strip material are each made of H-beam steel.

[0010] A building construction method according to a fifth aspect of the present invention is the building construction method according to the fourth aspect of the present invention, wherein the base member includes a position adjustment portion for adjusting the horizontal position of the furring strip material.

[0011] The building construction method described in claim 6 is a building construction method described in any one of claims 1 to 3, which includes a reinforcement process of providing reinforcing material to the first ground structure before the second advance construction process. [Effects of the Invention]

[0012] According to the building construction method described in claim 1, the method includes a second preceding construction step in which, after or during the first construction step, a portion of the second ground structure, including at least the exterior wall portion, is constructed in the second construction section while the portion is supported on the first ground structure, and a second following construction step in which, after the second preceding construction step, another portion of the second ground structure is constructed while the other portion is supported on the first ground structure. Therefore, when constructing the second ground structure after or during construction of the first ground structure, the second ground structure can be supported on the first ground structure, eliminating the need for temporary members, thereby improving the ease of construction of the building. Furthermore, by constructing the portion of the second ground structure, including the exterior wall portion, in advance, the impact of wind can be reduced when constructing the other portion of the second ground structure, thereby avoiding delays in construction of the building.

[0013] According to the building construction method described in claim 2, in the second advance construction process, a portion of the second ground structure including the exterior wall and roof portions is constructed. Therefore, by constructing a portion of the second ground structure in advance, the effects of wind and weather can be reduced when constructing other portions of the second ground structure, making it possible to further avoid delays in the construction of the building.

[0014] According to the building construction method described in claim 3, an air conditioning adjustment process is included after the second advance construction process to adjust the air conditioning in at least the second construction area, so that the air conditioning in at least the second construction area can be adjusted and various processes carried out in at least the second construction area after the air conditioning adjustment process can be carried out comfortably.

[0015] According to the building construction method described in claim 4, the outer wall portion of the second ground structure is connected to the column portion or beam portion of the second ground structure via an outer wall support material and a base member, and the base member comprises a support beam material and a furring strip material, and the support beam material and the furring strip material are each made of H-steel material, so that the support beam material and the furring strip material can be manufactured easily and inexpensively, and the manufacturability of the base member can be improved.

[0016] According to the building construction method described in claim 5, the base member is equipped with a position adjustment portion, which makes it possible to easily adjust the horizontal position of the furring strip material, thereby improving the ease of installation of the base member.

[0017] According to the building construction method described in claim 6, a reinforcement process of installing reinforcing materials on the first ground structure is included before the second preliminary construction process, so that when the second ground structure is constructed, the first ground structure can stably support the second ground structure, ensuring safety during the construction of the building.

[0043] In the following, as necessary, of the inner wall portions 27, the inner wall portion 27a of the first layer 21a will be referred to as the "first inner wall portion 27a," the inner wall portion 27b of the second layer 21b will be referred to as the "second inner wall portion 27b," the inner wall portion 27c of the third layer 21c will be referred to as the "third inner wall portion 27c," and the inner wall portion 27d of the fourth layer 21d will be referred to as the "fourth inner wall portion 27d."

[0044] (Building construction method) Next, the construction method for the building 1 will be described.

[0045] The construction method for this building 1 is a method for dividing building 1 into multiple construction sections and constructing it, and in the embodiment, as shown in Figures 2, 3, 6, and 7, includes a first construction section construction process, a first construction section second construction section construction process, a first air conditioning adjustment process, a first construction section third construction section construction process, a second air conditioning adjustment process, a second construction section third construction section construction process, a third air conditioning adjustment process, a third construction section construction process, and a finishing process.

[0046] (Building construction method - Construction process for the first section) First, we will explain the construction process for the first section.

[0047] The first construction section construction step is a step of constructing a part of a part of the first ground structure 10a (specifically, the columns 24 and beams 25 of each story 21 of the first ground structure 10a) in the first construction section 2a.

[0048] In the embodiment, as shown in FIG. 2, the columns 24 and beams 25 of the first ground structure 10a are constructed in the order from the first floor 21a to the fourth floor 21d (i.e., constructed sequentially from the lowest floor 21 to the highest floor 21) using a known construction method (e.g., a layering method) and known construction machinery (e.g., a crane, etc.) not shown.

[0049] (Building construction method - Construction process for the first section - Construction of the first floor of the first ground structure) First, for the construction of the first floor 21a on a part of a part of the first ground structure 10a, the first column portion 24a is finally fixed to the ground surface (or to a pile body installed underground), and then the first beam portion 25a is finally fixed to the first column portion 24a.

[0050] Here, "permanent fixation" means firmly fixing a component so that it cannot be removed from the object to be fixed. For example, when permanent fixation is performed using a bolt, this would include tightening the bolt so that the torque of the bolt is equal to or greater than a threshold value.

[0051] On the other hand, "temporary fixation" means that a component can be easily removed from the object to be fixed, but is fixed to such an extent that it will not fall off from the object to be fixed due to external forces such as vibration. For example, when temporarily fixing using a bolt, this would include tightening the bolt so that the torque of the bolt is less than a threshold value.

[0052] (Building construction method - Construction process for the first section - Construction of the second floor of the first ground structure) In addition, when constructing the second floor 21b on a part of a part of the first ground structure 10a, the second column portion 24b is finally fixed to the first column portion 24a or the first beam portion 25a, and then the second beam portion 25b is finally fixed to the second column portion 24b.

[0053] (Building construction method - Construction process for the first section - Construction of the third floor of the first ground structure) In addition, when constructing the third floor 21c on a part of a part of the first ground structure 10a, the third column portion 24c is finally fixed to the second column portion 24b or the second beam portion 25b, and then the third beam portion 25c is finally fixed to the third column portion 24c.

[0054] (Building construction method - Construction process for the first section - Construction of the fourth floor of the first ground structure) In addition, when constructing the fourth story 21d on a part of a part of the first ground structure 10a, the fourth column portion 24d is finally fixed to the third column portion 24c or the third beam portion 25c, and then the fourth beam portion 25d is finally fixed to the fourth column portion 24d.

[0055] This first section construction process allows the first section 2a, located at the edge of the construction area 2, to be constructed first, making it easier to formulate an efficient construction plan for the building 1 (for example, a plan for transporting components, a plan for deploying workers, etc.) compared to when the second section 2b, located in the center, is constructed first.

[0056] (Building construction method - Construction process for the first and second sections) Next, we will explain the construction process for the second section of the first section.

[0057] The construction process for the second section of the first construction area is a process in which another part of a part of the first ground structure 10a (specifically, the exterior wall section 26 of each story 21 of the first ground structure 10a and the roof section 23 of the first ground structure 10a) is constructed in the first construction area 2a, and a part of a part of the second ground structure 10b (specifically, the column section 24 and beam section 25 of each story 21 of the second ground structure 10b) is constructed in the second construction area 2b.

[0058] In this embodiment, as shown in Figure 3, the exterior wall portions 26 of each story 21 in the first ground structure 10a are installed against the column portions 24 and / or beam portions 25 of each story 21 in the first ground structure 10a using known construction machinery.

[0059] In addition, using a known construction method (for example, a folding screen construction method) and known construction machinery, the columns 24 and beams 25 of the second ground structure 10b are constructed in the order from the first floor 21a to the fourth floor 21d, while the columns 24 and beams 25 of the second ground structure 10b are supported by the columns 24 and / or beams 25 of the first ground structure 10a.

[0060] The construction order of the construction process for the second construction section of the first construction section is arbitrary, but in this embodiment, a part of a part of the second ground structure 10b is constructed after another part of a part of the first ground structure 10a is constructed.

[0061] However, this is not limiting, and for example, after constructing a part of a part of the second ground structure 10b, another part of a part of the first ground structure 10a may be constructed. Alternatively, another part of a part of the first ground structure 10a and a part of a part of the second ground structure 10b may be constructed simultaneously.

[0062] (Building construction method - Construction process of the first construction section, second construction section - Construction of the first above-ground structure) Here, in constructing the roof portion 23 of the first ground structure 10a, the roof portion 23 is permanently fixed to the fourth column portion 24d or the fourth beam portion 25d.

[0063] Furthermore, with regard to the construction of the exterior wall portion 26 of the first ground structure 10a, as shown in Figure 3, on each floor 21, the exterior wall portion 26 is connected to the column portion 24 or beam portion 25 of the first ground structure 10a via the exterior wall support material 30 and the base material 40 (specifically, the exterior wall portion 26 is permanently fixed to the column portion 24 or beam portion 25 of the first ground structure 10a).

[0064] (Building construction method - Construction process of the first and second sections - Construction of the first above-ground structure - Exterior wall support material) Here, the exterior wall support material 30 is a member for connecting the exterior wall portion 26 to the column portion 24 or the beam portion 25 of the first ground structure 10a. This exterior wall support material 30 is constructed using, for example, a known support material (for example, a long steel support material), and a plurality of such materials are provided on each story 21.

[0065] Specifically, as shown in Figures 4 and 5, the exterior wall support material 30 is arranged so that the longitudinal direction of the exterior wall support material 30 is along the vertical direction, and multiple pieces are arranged side by side at predetermined intervals approximately along the horizontal direction, and are connected to the exterior wall portion 26 by fixing devices or the like.

[0066] (Building construction method - Construction process of the first and second sections - Construction of the first above-ground structure - Base materials) In addition, the base member 40 is a member for connecting the outer wall portion 26 to the column portion 24 or beam portion 25 of the first ground structure 10a, and as shown in Figure 5, it is equipped with a support beam material 41, a furring strip material 42, and a position adjustment portion 43.

[0067] (Building construction method - Construction process of the first and second sections - Construction of the first above-ground structure - Base materials - Support beams) Of these, the support beams 41 are part of the basic structure of the base member 40. The support beams 41 are long bodies, and as shown in Fig. 5, they are provided between the column parts 24 or beam parts 25 of each story 21 and the exterior wall support material 30 so that the longitudinal direction of the support beams 41 is approximately along the horizontal direction, and are connected to the column parts 24 or beam parts 25 of each story 21 and the exterior wall support material 30 by fasteners, welding, or the like.

[0068] (Building construction method - Construction process of the first and second sections - Construction of the first above-ground structure - Base materials - Furring strips) The furring strips 42 are another part of the basic structure of the base member 40. The furring strips 42 are elongated bodies, and as shown in Fig. 5, are arranged between the exterior wall support members 30 of adjacent stories 21 so that the longitudinal direction of the support beams 41 is substantially horizontal, and are arranged to abut against the exterior wall portions 26 and the support beams 41, and are connected to the support beams 41 via position adjustment portions 43.

[0069] Furthermore, the specific configuration of the support beam material 41 and the furring strip material 42 is arbitrary, but in the embodiment, the support beam material 41 and the furring strip material 42 are each made of H-beam steel.

[0070] This allows the support beam material 41 and the furring strip material 42 to be manufactured simply and inexpensively, thereby improving the manufacturability of the base member 40.

[0071] However, the present invention is not limited to this, and for example, the support beam material 41 and the furring strip material 42 may be made of steel material other than H-beam steel (for example, C-beam steel, etc.).

[0072] (Building construction method - Construction process of the first construction section, second construction section - Construction of the first above-ground structure - Base material - Position adjustment section) The position adjustment section 43 is used to adjust the horizontal position of the furring strip 42, and as shown in FIG. 5, includes a position adjustment section main body 43a and an elongated hole section 43b.

[0073] Of these, the position adjustment unit main body 43a is the basic structure of the position adjustment unit 43. This position adjustment unit main body 43a is constructed using a known angle bar (a steel angle bar, for example) that has a vertical piece and a horizontal piece, and as shown in Fig. 5, it is placed on the top surface of the support beam material 41, inside the furring strips 42 of the building 1, and is connected to the furring strips 42 by welding or a fastener or the like (alternatively, it may be formed integrally with the furring strips 42).

[0074] The elongated hole 43b is a long through-hole for adjusting the horizontal position of the furring strip 42. As shown in Fig. 5, the elongated hole 43b is provided in the vertical piece of the position adjustment part main body 43a so that the longitudinal direction of the elongated hole 43b is along the approximately horizontal direction, and a plurality of elongated hole 43b are arranged side by side at intervals along the horizontal direction (two are arranged side by side in Fig. 5). However, this is not limiting, and only one elongated hole 43b may be provided in the vertical piece of the position adjustment part main body 43a.

[0075] Furthermore, the method of connecting the position adjustment portion 43 and the supporting beam material 41 is arbitrary, but in the embodiment, the position adjustment portion 43 and the supporting beam material 41 are connected by inserting bolt members (not shown) into multiple through holes (not shown) provided in a connecting piece (not shown) attached to the supporting beam material 41 and into multiple long hole portions 43b of the position adjustment portion 43, and then attaching nut members to each of these bolt members.

[0076] This allows the horizontal position of the furring strip material 42 to be easily adjusted, making it possible to improve the ease of installation of the base member 40.

[0077] (Building construction method - Construction process of the 1st construction section, 2nd construction section - Construction of the 2nd above-ground structure) Returning to FIG. 3, construction of a portion of the second ground structure 10b is as follows in this embodiment.

[0078] (Building construction method - Construction process for the first and second sections - Construction of the second above-ground structure - First floor) First, for the construction of the first story 21a on a part of a part of the second ground structure 10b, the first column 24a of the second ground structure 10b is permanently fixed to the ground surface. Also, the first beam 25a of the second ground structure 10b is temporarily fixed to the first column 24a of the second ground structure 10b, and is also temporarily fixed to the first beam 25a or the first column 24a of the first ground structure 10a.

[0079] The reason for temporarily fixing the first beam portion 25a of the second ground structure 10b is that if the first beam portion 25a of the second ground structure 10b were to be permanently fixed at this time, it would be necessary to install temporary materials near the first column portion 24a of the second ground structure 10b, etc., but since the installation of temporary materials is not necessarily required when temporarily fixing the first beam portion 25a, it is possible to omit the work of installing temporary materials (note that the reasons for temporarily fixing the other beam portions 25 are substantially the same).

[0080] It should be noted that "temporary components" refer to components that are temporarily installed on or around the ground structure 10 to allow workers to work safely, and include, for example, temporary scaffolding (e.g., topics, columns, horizontal nets), temporary equipment, etc.

[0081] However, this is not limited to this, and for example, the first beam portion 25a of the second ground structure 10b may be fixed to the first column portion 24a of the second ground structure 10b, and may also be fixed to the first beam portion 25a or the first column portion 24a of the first ground structure 10a (note that the same applies to the second beam portion 25b, third beam portion 25c, and fourth beam portion 25d of the second ground structure 10b).

[0082] (Building construction method - Construction process for the 1st construction section, 2nd construction section - Construction of the 2nd above-ground structure - 2nd floor) Furthermore, with regard to the construction of the second floor 21b on a part of a part of the second ground structure 10b, after the second column portion 24b of the second ground structure 10b is permanently fixed to the first column portion 24a of the second ground structure 10b, the second beam portion 25b of the second ground structure 10b is temporarily fixed to the second column portion 24b of the second ground structure 10b, and is also temporarily fixed to the second beam portion 25b or the second column portion 24b of the first ground structure 10a.

[0083] (Building construction method - Construction process for the 1st construction section, 2nd construction section - Construction of the 2nd above-ground structure - 3rd floor) Furthermore, the construction of the third story 21c on a part of a part of the second ground structure 10b is carried out in substantially the same manner as the construction of the second story 21b on a part of a part of the second ground structure 10b described above.

[0084] (Building construction method - Construction process for the 1st construction section, 2nd construction section - Construction of the 2nd above-ground structure - 4th floor) Furthermore, the construction of the fourth story 21d on a part of a part of the second ground structure 10b is carried out in substantially the same manner as the construction of the second story 21b on a part of a part of the second ground structure 10b described above.

[0085] (Building construction method - Construction process of the first and second sections - Construction of the second above-ground structure - Other) Furthermore, the specific configuration of the first ground structure 10a and the second ground structure 10b during the construction process of the second work section of the first work section is arbitrary, but in the embodiment, a portion of the first ground structure 10a is configured to be able to support the horizontal force of a portion of the first ground structure 10a and the horizontal force of a portion of the second ground structure 10b, as well as the vertical force of a portion of the first ground structure 10a, and a portion of a portion of the second ground structure 10b is configured to be able to support the vertical force of that portion (note that the specific configuration of the second ground structure 10b and the third ground structure 10c during the construction process of the third work section of the first work section described below, and the specific configuration of the second ground structure 10b and the third ground structure 10c during the construction process of the third work section of the second work section described below are approximately the same).

[0086] Specifically, for a portion of the first ground structure 10a, the shape, size (specifically, the length in the left-right direction, the length in the front-to-back direction, and the length in the up-to-down direction) and material of the various components of the first ground structure 10a (specifically, the roof portion 23, the column portion 24, the beam portion 25, the outer wall portion 26, and the inner wall portion 27) are set so that they can withstand the horizontal force of the first ground structure 10a, the horizontal force of the second ground structure 10b, and the vertical force of the first ground structure 10a that may act on the first ground structure 10a according to the design.

[0087] In addition, the shape, size, and material of various components of a portion of the second ground structure 10b (specifically, the column portion 24 and the beam portion 25) are set so that the portion can withstand only the vertical force of the second ground structure 10b that may act on the second ground structure 10b according to the design.

[0088] With this configuration, when constructing a portion of a portion of the second ground structure 10b, a portion of the first ground structure 10a can reliably support a portion of a portion of the second ground structure 10b, allowing the portion of the portion of the second ground structure 10b to be constructed safely. Also, it is possible to avoid setting the strength of the portion of the portion of the second ground structure 10b too high, ensuring the manufacturability of the portion of the portion of the second ground structure 10b.

[0089] Furthermore, the above-described construction process for the first construction section and second construction section allows a portion of the second ground structure 10b to be supported on the first ground structure 10a when constructing that portion, eliminating the need for temporary materials, thereby improving the ease of construction of that portion of the second ground structure 10b. Furthermore, by constructing a portion of the first ground structure 10a in advance, the effects of wind and weather can be reduced when constructing the other portion of the first ground structure 10a, thereby avoiding delays in construction. In particular, because the floor 22 of the first ground structure 10a is made of concrete, concrete pouring for that floor 22 can be performed in all weather conditions, preventing delays in construction of that floor 22 due to rain, etc.

[0090] During the construction of the first construction section, second construction section construction process, the first ground structure 10a corresponds to the "first ground structure" in the claims, and the second ground structure 10b corresponds to the "second ground structure" in the claims. Furthermore, during the first construction section construction process and the first construction section, second construction section construction process, the process of constructing another part of the first ground structure 10a corresponds to the "first construction process" in the claims. Furthermore, during the first construction section, second construction section construction process, the process of constructing a part of a part of the second ground structure 10b corresponds to the "second preceding construction process" in the claims (specifically, the "second preceding construction process" carried out during the first construction process).

[0091] (Building construction method - First air conditioning adjustment process) Next, the first air conditioning adjustment step will be described.

[0092] The first air conditioning adjustment process is an air conditioning adjustment process for adjusting the air conditioning in the first construction section 2a after the first construction section second construction section construction process.

[0093] In this embodiment, a known air conditioning device (for example, a heating and cooling device and / or a ventilation device, etc.) is installed on at least one or more floors 21 of the first ground structure 10a, and the air conditioning within the first construction area 2a is adjusted by operating the air conditioning device.

[0094] In this embodiment, the first air conditioning adjustment process is performed until the finishing process is completed. However, this is not limiting, and the implementation may be terminated, for example, when the construction process of the third work section of the first work section is completed.

[0095] This first air conditioning adjustment process allows the air conditioning within the first construction area 2a to be adjusted, making it possible to comfortably carry out various processes (e.g., the construction process of the third construction section of the first construction area, the finishing process, etc.) that are carried out within the first construction area 2a after the first air conditioning adjustment process.

[0096] (Building construction method - Construction process for Section 1, Section 3) Next, we will explain the construction process for the third section of the first construction section.

[0097] The construction process for the third section of the first construction section is a process in which another portion of the first ground structure 10a (specifically, the floors 22 and interior walls 27 of each story 21 of the first ground structure 10a) is constructed in the first construction section 2a, another portion of a portion of the second ground structure 10b (specifically, the exterior walls 26 of each story 21 of the second ground structure 10b and the roof 23 of the second ground structure 10b) is constructed in the second construction section 2b, and a portion of a portion of the third ground structure 10c (specifically, the columns 24 and beams 25 of each story 21 of the third ground structure 10c) is constructed in the third construction section 2c.

[0098] In this embodiment, as shown in Figure 6, the floors 22 and interior walls 27 of each story 21 in the first ground structure 10a are installed against the columns 24, beams 25, and / or ground surface of each story 21 in the first ground structure 10a using known construction machinery.

[0099] In addition, using a known construction method (for example, a folding screen construction method) and known construction machinery, the outer wall portion 26 and roof portion 23 of the second ground structure 10b are constructed while being supported by the first ground structure 10a.

[0100] In addition, using a known construction method (for example, a folding screen construction method) and known construction machinery, the columns 24 and beams 25 of the third ground structure 10c are constructed in the order from the first floor 21a to the fourth floor 21d, while the columns 24 and beams 25 of the third ground structure 10c are supported by the columns 24 and / or beams 25 of the second ground structure 10b.

[0101] The construction order of the construction process for the third construction section of the first construction section is arbitrary, but in this embodiment, another part of the first ground structure 10a is constructed first, then another part of a part of the second ground structure 10b is constructed, and then a part of a part of the third ground structure 10c is constructed.

[0102] However, this is not limiting, and for example, another part of a part of the second ground structure 10b may be constructed first, then another part of the first ground structure 10a, and then a part of a part of the third ground structure 10c may be constructed. Alternatively, another part of a part of the second ground structure 10b, another part of the first ground structure 10a, and a part of a part of the third ground structure 10c may be constructed simultaneously.

[0103] (Building construction method - Construction process of the 1st construction section, 3rd construction section - Construction of the 1st above-ground structure) Here, construction of the floor portion 22 of the first ground structure 10a is carried out as follows.

[0104] That is, in constructing the first story 21a of the first ground structure 10a, first, a formwork for the first floor 22a of the first ground structure 10a (for example, a formwork including a felled deck) is installed on the ground surface, concrete is poured into the formwork, and the concrete is allowed to harden for a predetermined period of time, thereby installing the first floor 22a of the first ground structure 10a on the ground surface. Accordingly, the first column 24a and the first outer wall 26a are permanently fixed to the first floor 22a.

[0105] Regarding the construction of the second story 21b of the first ground structure 10a, first, formwork for the second floor 22b of the first ground structure 10a is installed above the first columns 24a and first beams 25a, concrete is poured into the formwork, and the concrete is allowed to harden for a predetermined period of time, thereby installing the second floor 22b on the first columns 24a and first beams 25a. Accordingly, the second columns 24b and second outer wall 26b are permanently fixed to the second floor 22b.

[0106] The construction of the third story 21c and fourth story 21d of the first ground structure 10a is carried out in substantially the same manner as the construction of the second story 21b of the first ground structure 10a described above.

[0107] In addition, regarding the construction of the inner wall portions 27 of the first ground structure 10a, the inner wall portions 27 are permanently fixed to the columns 24 or beams 25 of the first ground structure 10a on each story 21.

[0108] Furthermore, the method for installing the inner wall portions 27 is arbitrary, but in this embodiment, by installing fewer than the number that should be installed, workability in the processes from the first construction section, third construction section construction process onwards is ensured. However, this is not limited to this, and for example, all of the number that should be installed may be installed (note that the installation method for the inner wall portions 27 in other processes (excluding the finishing process) is approximately the same).

[0109] (Building construction method - Construction process of the 1st construction section, 3rd construction section - Construction of the 2nd above-ground structure) In addition, when constructing the roof portion 23 of the second ground structure 10b, the roof portion 23 is temporarily fixed to the fourth column portion 24d or the fourth beam portion 25d.

[0110] However, the present invention is not limited to this, and for example, the roof portion 23 may be permanently fixed to the fourth pillar portion 24d or the fourth beam portion 25d.

[0111] Furthermore, the construction of the exterior wall portion 26 of the second ground structure 10b is carried out in substantially the same manner as the construction of the exterior wall portion 26 of the first ground structure 10a described above, in that the exterior wall portion 26 is connected to the column portion 24 or beam portion 25 of the second ground structure 10b on each floor 21 via the exterior wall support material 30 and the base member 40 (specifically, the exterior wall portion 26 is permanently fixed to the column portion 24 or beam portion 25 of the second ground structure 10b).

[0112] The specific configuration of the exterior wall support material 30 and the base material 40 is arbitrary, but in this embodiment, they are configured in approximately the same way as the exterior wall support material 30 and base material 40 used in constructing the exterior wall portion 26 of the first ground structure 10a described above.

[0113] (Building construction method - Construction process of the 3rd section of the 1st section - Construction of the 3rd above-ground structure) In addition, in this embodiment, the construction of a portion of the third ground structure 10c is carried out in approximately the same manner as the construction of a portion of the second ground structure 10b in the first construction section, second construction section construction process described above.

[0114] Through the above-described construction process for the first section, third section, the second ground structure 10b can be partially supported on the first ground structure 10a when constructing the second ground structure 10b, eliminating the need for temporary structures. This improves the ease of construction of the second ground structure 10b. Furthermore, the third ground structure 10c can be partially supported on the second ground structure 10b when constructing the third ground structure 10c, eliminating the need for temporary structures. This improves the ease of construction of the third ground structure 10c. Furthermore, by constructing the second ground structure 10b in advance, the effects of wind and weather on the construction of the remaining portion of the second ground structure 10b can be reduced, thereby avoiding construction delays. In particular, because the floor 22 of the second ground structure 10b is made of concrete, concrete pouring for the floor 22 can be performed in all weather conditions, eliminating delays in construction of the floor 22 due to rain, etc.

[0115] During the construction of the second ground structure 10b in the first construction section, third construction section construction process, the first ground structure 10a corresponds to the "first ground structure" in the claims, and the second ground structure 10b corresponds to the "second ground structure" in the claims. Also, the process of constructing another part of the first ground structure 10a in the first construction section construction process and the first construction section, second construction section construction process, and the process of constructing another part of the first ground structure 10a in the first construction section, third construction section construction process correspond to the "first construction process" in the claims. In addition, the process of constructing a part of a part of the second ground structure 10b in the construction process of the second work section of the first work section, and the process of constructing another part of a part of the second ground structure 10b in the construction process of the third work section of the first work section correspond to the ``second advance construction process'' in the claims (specifically, the ``second advance construction process'' that is carried out in the middle of the first construction process).

[0116] Furthermore, during the construction of the third ground structure 10c in the construction process of the third work section of the first work section, the second ground structure 10b corresponds to the "first ground structure" in the claims, and the third ground structure 10c corresponds to the "second ground structure" in the claims. Furthermore, the process of constructing a part of a part of the second ground structure 10b in the construction process of the second work section of the first work section, and the process of constructing another part of a part of the second ground structure 10b in the construction process of the third work section of the first work section, correspond to the "first construction process" in the claims. Furthermore, the process of constructing a part of a part of the third ground structure 10c in the construction process of the third work section of the first work section corresponds to the "second preceding construction process" in the claims (specifically, the "second preceding construction process" carried out during the first construction process).

[0117] (Building construction method - 2nd air conditioning adjustment process) Next, the second air conditioning adjustment step will be described.

[0118] The second air conditioning adjustment process is an air conditioning adjustment process for adjusting the air conditioning in the second construction section 2b after the first construction section third construction section construction process.

[0119] In this embodiment, similar to the first air conditioning adjustment process, a known air conditioning device is installed on at least one or more floors 21 of the second ground structure 10b, and then the air conditioning within the second construction area 2b is adjusted by operating the air conditioning device.

[0120] In this embodiment, the second air conditioning adjustment process is performed until the finishing process is completed. However, this is not limiting, and the implementation may be terminated, for example, when the second construction section, third construction section construction process is completed.

[0121] This second air conditioning adjustment process allows the air conditioning within the second construction area 2b to be adjusted, making it possible to comfortably carry out various processes (e.g., construction process of the third construction section of the second construction area, finishing process, etc.) that are carried out within the second construction area 2b after the second air conditioning adjustment process.

[0122] (Building construction method - Construction process for the 2nd and 3rd sections) Next, we will explain the construction process for the third section of the second construction section.

[0123] The construction process of the third section of the second construction section is a process of constructing another part of the second ground structure 10b (specifically, the floor section 22 and interior wall section 27 of each story 21 of the second ground structure 10b) in the second construction section 2b, and constructing another part of a part of the third ground structure 10c (specifically, the exterior wall section 26 of each story 21 of the third ground structure 10c and the roof section 23 of the third ground structure 10c) in the third construction section 2c.

[0124] In the embodiment, as shown in Figure 7, using a known construction method (for example, folding screen construction method) and known construction machinery, the floors 22 and inner walls 27 of each story 21 of the second ground structure 10b are constructed while the floors 22 and inner walls 27 of each story 21 of the second ground structure 10b are supported by the first ground structure 10a.

[0125] In addition, using a known construction method (for example, a folding screen construction method) and known construction machinery, the outer wall portion 26 and roof portion 23 of the third ground structure 10c are constructed while being supported by the second ground structure 10b.

[0126] The construction order of the construction process for the second construction section, third construction section is arbitrary, but in this embodiment, another part of the second ground structure 10b is constructed first, and then another part of a part of the third ground structure 10c is constructed.

[0127] However, the present invention is not limited to this, and for example, another part of the third ground structure 10c may be constructed first, followed by another part of the second ground structure 10b. Alternatively, another part of the second ground structure 10b and another part of the third ground structure 10c may be constructed simultaneously.

[0128] (Building construction method - Construction process for the 2nd construction section, 3rd construction section - Construction of the 2nd above-ground structure) Here, construction of the floor portion 22 of the second ground structure 10b is carried out as follows.

[0129] That is, in constructing the first story 21a of the second ground structure 10b, first, a form for the first floor 22a of the second ground structure 10b is installed on the ground surface, concrete is poured into the form, and the concrete is allowed to harden for a predetermined period of time, thereby installing the first floor 22a of the first ground structure 10a on the ground surface and connecting it to the first floor 22a of the first ground structure 10a. After that, the first beam 25a of the second ground structure 10b is finally fixed to the first column 24a of the second ground structure 10b, and is also finally fixed to the first beam 25a or the first column 24a of the first ground structure 10a.

[0130] Regarding the construction of the second story 21b of the second ground structure 10b, first, formwork for the second floor 22b of the second ground structure 10b is installed above the first columns 24a and first beams 25a, concrete is poured into the formwork, and the concrete is allowed to harden for a predetermined period of time, thereby installing the second floor 22b on the first columns 24a and first beams 25a. Then, after the second columns 24b are permanently fixed to the second floor 22b, the second beams 25b are permanently fixed to the second floor 22b or the second columns 24b.

[0131] The construction of the third story 21c of the second ground structure 10b is carried out in substantially the same manner as the construction of the second story 21b of the second ground structure 10b described above.

[0132] Furthermore, the construction of the fourth floor 21d of the second ground structure 10b is carried out in substantially the same manner as the construction of the second floor 21b of the second ground structure 10b described above, and then the roof portion 23 of the second ground structure 10b is finally fixed to the fourth beam portion 25d or the fourth column portion 24d of the second ground structure 10b.

[0133] The construction of the inner wall portion 27 of the second ground structure 10b is carried out in substantially the same manner as the construction of the inner wall portion 27 of the first ground structure 10a in the first construction section, third construction section construction step described above.

[0134] (Building construction method - Construction process of the 2nd construction section, 3rd construction section - Construction of the 3rd above-ground structure) In addition, when constructing the roof portion 23 of the third ground structure 10c, the roof portion 23 is temporarily fixed to the fourth column portion 24d or the fourth beam portion 25d.

[0135] However, the present invention is not limited to this, and for example, the roof portion 23 may be permanently fixed to the fourth pillar portion 24d or the fourth beam portion 25d.

[0136] Furthermore, the construction of the exterior wall portion 26 of the third ground structure 10c is carried out in substantially the same manner as the construction of the exterior wall portion 26 of the first ground structure 10a described above, in that the exterior wall portion 26 is connected to the column portion 24 or beam portion 25 of the second ground structure 10b on each floor 21 via the exterior wall support material 30 and the base member 40 (specifically, the exterior wall portion 26 is permanently fixed to the column portion 24 or beam portion 25 of the second ground structure 10b).

[0137] Through the above-described construction process for the second construction section, third construction section, when constructing another portion of the second ground structure 10b, the other portion of the second ground structure 10b can be supported on the first ground structure 10a, eliminating the need for temporary structures, thereby improving the workability of the other portion of the second ground structure 10b. Furthermore, when constructing a portion of the third ground structure 10c, the other portion of the third ground structure 10c can be supported on the second ground structure 10b, eliminating the need for temporary structures, thereby improving the workability of the portion of the third ground structure 10c. Furthermore, by constructing a portion of the third ground structure 10c in advance, the effects of wind and weather can be reduced when constructing the other portion of the third ground structure 10c, thereby avoiding delays in the construction. In particular, since the floor 22 of the third ground structure 10c is made of concrete, concrete can be poured for the floor 22 in all weather conditions, and delays in construction of the floor 22 due to rain or the like can be avoided.

[0138] During the construction of the second ground structure 10b in the second construction section, third construction section construction process, the first ground structure 10a corresponds to the "first ground structure" in the claims, and the second ground structure 10b corresponds to the "second ground structure" in the claims. Also, the process of constructing another part of the first ground structure 10a in the first construction section construction process and the first construction section, second construction section construction process, and the process of constructing another part of the first ground structure 10a in the first construction section, third construction section construction process correspond to the "first construction process" in the claims. Furthermore, the process of constructing a portion of the second ground structure 10b in the construction process of the second section of the first construction zone, and the process of constructing a portion of the second ground structure 10b in the construction process of the third section of the first construction zone, correspond to the "second preceding construction process" in the claims (specifically, the "second preceding construction process" carried out during the first construction process). Furthermore, the process of constructing another portion of the second ground structure 10b in the construction process of the third section of the second construction zone, corresponds to the "second subsequent construction process" in the claims.

[0139] Furthermore, during the construction of the third ground structure 10c in the second construction section, third section construction process, the second ground structure 10b corresponds to the "first ground structure" in the claims, and the third ground structure 10c corresponds to the "second ground structure" in the claims. Furthermore, the process of constructing a part of a part of the second ground structure 10b in the first construction section, second section construction process, the process of constructing another part of a part of the second ground structure 10b in the first construction section, third section construction process, and the process of constructing another part of the second ground structure 10b in the second construction section, third section construction process correspond to the "first construction process" in the claims. In addition, the process of constructing a part of a part of the third ground structure 10c in the construction process of the third section of the first construction area, and the process of constructing another part of a part of the third ground structure 10c in the construction process of the third section of the second construction area, correspond to the ``second advance construction process'' in the claims (specifically, the ``second advance construction process'' that is carried out in the middle of the first construction process).

[0140] (Building construction method - 3rd air conditioning adjustment process) Next, the third air conditioning adjustment step will be described.

[0141] The third air conditioning adjustment process is an air conditioning adjustment process for adjusting the air conditioning in the third construction section 2c after the second construction section third construction section construction process.

[0142] In this embodiment, similarly to the second air conditioning adjustment process, a known air conditioning device is installed on at least one or more floors 21 of the third ground structure 10c, and then the air conditioning within the third construction area 2c is adjusted by operating the air conditioning device.

[0143] This third air conditioning adjustment process allows the air conditioning within the third construction area 2c to be adjusted, making it possible to comfortably carry out various processes (e.g., third construction area construction process, finishing process, etc.) that are carried out within the third construction area 2c after the third air conditioning adjustment process.

[0144] In this embodiment, the second air conditioning adjustment process is performed until the finishing process is completed. However, this is not limiting, and the implementation may be completed, for example, when the third construction section construction process is completed.

[0145] (Building construction method - Third construction section construction process) Next, we will explain the construction process for the third section.

[0146] The third construction section construction process is a process of constructing another part of the third ground structure 10c (specifically, the floor section 22 and interior wall section 27 of each story 21 of the third ground structure 10c) in the third construction section 2c after the third air conditioning adjustment process.

[0147] In the embodiment, using a known construction method (for example, folding screen construction method) and known construction machinery, the floors 22 and inner walls 27 of each story 21 of the third ground structure 10c are constructed while the floors 22 and inner walls 27 of each story 21 of the third ground structure 10c are supported by the second ground structure 10b.

[0148] Specifically, the construction of the floor 22 of the third ground structure 10c is carried out in substantially the same manner as the construction of the floor 22 of the second ground structure 10b in the second construction section, third construction section construction step described above.

[0149] The construction of the inner wall portion 27 of the third ground structure 10c is carried out in substantially the same manner as the construction of the inner wall portion 27 of the second ground structure 10b in the second construction section, third construction section construction step described above.

[0150] By performing the above-described third section construction process, when constructing another part of the third ground structure 10c, the other part of the third ground structure 10c can be supported on the second ground structure 10b, and there is no need to install temporary members, thereby improving the workability of the other part of the third ground structure 10c.

[0151] During the construction of the third construction section construction process, the second ground structure 10b corresponds to the "first ground structure" in the claims, and the third ground structure 10c corresponds to the "second ground structure" in the claims. Also, the process of constructing a part of a part of the second ground structure 10b in the third construction section construction process, the process of constructing another part of a part of the second ground structure 10b in the first construction section third construction section construction process, and the process of constructing another part of the second ground structure 10b in the second construction section third construction section construction process correspond to the "first construction process" in the claims. Furthermore, the process of constructing a part of a part of the third ground structure 10c in the construction process of the third section of the first construction area, and the process of constructing another part of a part of the third ground structure 10c in the construction process of the third section of the second construction area, correspond to the "second preceding construction process" in the claims (specifically, the "second preceding construction process" carried out during the first construction process). Furthermore, the construction process of the third construction area corresponds to the "second subsequent construction process" in the claims.

[0152] (Building construction method - finishing process) Next, the finishing process will be described.

[0153] The finishing process is a process of finishing building 1 after the third construction section construction process.

[0154] Specifically, the remaining members (for example, the remaining inner wall portions 27, etc.) in the first ground structure 10a to the third ground structure 10c are permanently fixed to the corresponding floor portions 22, beam portions 25, column portions 24, outer wall portions 26, or inner wall portions 27.

[0155] In addition, exterior construction work (e.g., painting work on the exterior surface of the exterior wall 26 or roof 23) and interior construction work (e.g., painting work on the interior surface of the exterior wall 26, interior wall 27, or floor 22) of the building 1 is carried out on the first ground structure 10a to the third ground structure 10c.

[0156] In addition, heavy construction machinery and various equipment (e.g., air conditioning equipment) used in each process will be removed.

[0157] Through such a finishing process, the building 1 shown in FIG. 1 can be constructed.

[0158] With the construction method of the building 1 described above, when one of the two adjacent ground-based structures 10 of the building 1 is constructed after or during the construction of the other ground-based structure 10, the other ground-based structure 10 can be supported by the other ground-based structure 10, eliminating the need to install temporary members, thereby improving the constructability of the building 1. Furthermore, by constructing a portion of the other ground-based structure 10 including the exterior wall portion 26 in advance, the effects of wind can be reduced when constructing the other portion of the other ground-based structure 10, making it possible to avoid delays in the construction of the building 1.

[0159] (Effects of the embodiment) Thus, according to the embodiment, after or during the first construction process, a second preceding construction process is performed in the second construction section, in which a portion of the second ground structure 10, including at least the exterior wall portion 26, is constructed while the portion is supported on the first ground structure 10, and a second following construction process is performed after the second preceding construction process, in which another portion of the second ground structure 10 is constructed while the other portion is supported on the first ground structure 10. Therefore, when constructing the second ground structure 10 after or during the construction of the first ground structure 10, the second ground structure 10 can be supported on the first ground structure 10, eliminating the need for temporary members, thereby improving the constructability of the building 1. Furthermore, by constructing the portion of the second ground structure 10, including the exterior wall portion 26, in advance, the effects of wind can be reduced when constructing the other portion of the second ground structure 10, thereby making it possible to avoid delays in the construction of the building 1.

[0160] Furthermore, in the second advance construction process, a portion of the second ground structure 10 including the exterior wall portion 26 and the roof portion 23 is constructed. Therefore, by constructing a portion of the second ground structure 10 in advance, the effects of wind and weather can be reduced when constructing other portions of the second ground structure 10, thereby making it possible to further avoid delays in the construction of the building 1.

[0161] In addition, since the second advance construction process includes an air conditioning adjustment process for adjusting the air conditioning in at least the second construction area, the air conditioning in at least the second construction area can be adjusted, making it possible to comfortably carry out various processes that are carried out in at least the second construction area after the air conditioning adjustment process.

[0162] In addition, the outer wall portion 26 of the second ground structure 10 is connected to the column portion 24 or beam portion 25 of the second ground structure 10 via the outer wall support material 30 and the base member 40, and the base member 40 is provided with a support beam material 41 and a furring strip material 42, and the support beam material 41 and the furring strip material 42 are each made of H-steel material, so that the support beam material 41 and the furring strip material 42 can be manufactured easily and inexpensively, thereby improving the manufacturability of the base member 40.

[0163] Furthermore, since the base member 40 is provided with a position adjustment portion 43, the horizontal position of the furring strip material 42 can be easily adjusted, thereby improving the ease of installation of the base member 40.

[0164] [III] Modifications to the embodiment Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions set forth in the claims. Such modifications will be described below.

[0165] (About the problem to be solved and the effects of the invention) First, the problems to be solved by the invention and the effects of the invention are not limited to those described above, and the present invention may solve problems not described above or achieve effects not described above. Also, the present invention may solve only some of the problems described or achieve only some of the effects described.

[0166] (shape, numbers, structure, time series) The components illustrated in the embodiments and drawings may be modified and improved as desired within the scope of the technical concept of the present invention in terms of shape, numerical value, or the structure or chronological relationship of multiple components.

[0167] (About the building) In the above embodiment, the floor portion 22 is described as being made of concrete, but the present invention is not limited to this and may be made of, for example, a material other than concrete (for example, steel).

[0168] In the above embodiment, a portion of the second ground structure 10b is described as including the exterior wall portion 26 and the roof portion 23, but this is not limited to this. For example, a portion of the second ground structure 10b may include the exterior wall portion 26, and another portion of the second ground structure 10b may include the roof portion 23 (note that the same applies to a portion of the third ground structure 10c).

[0169] Furthermore, in the above embodiment, the exterior wall portion 26 of the ground structure 10 is described as being connected to the columns 24 or the beams 25 via the exterior wall support material 30 and the base member 40, but this is not limiting. For example, it may be connected directly to the columns 24 or the beams 25. Alternatively, the exterior wall portion 26 may be reinforced by further attaching exterior wall reinforcing members (for example, buttress members or vertical surface frames provided at predetermined intervals) to the inner surface of the exterior wall portion 26.

[0170] (About the base material) In the above embodiment, the base member 40 is described as having the position adjustment portion 43, but this is not limiting, and for example, the position adjustment portion 43 may be omitted.

[0171] (About the construction method of the building) In the above embodiment, the construction method for building 1 has been described as including the first air conditioning adjustment step, the second air conditioning adjustment step, the third air conditioning adjustment step, and the finishing step, but is not limited to this. For example, at least one of the first air conditioning adjustment step, the second air conditioning adjustment step, the third air conditioning adjustment step, and the finishing step may be omitted.

[0172] For example, when the first air conditioning adjustment step is omitted, the air conditioning in the first work area 2a and the second work area 2b may be adjusted in the second air conditioning adjustment step. Also, when the first air conditioning adjustment step and the second air conditioning adjustment step are omitted, the air conditioning in the first work area 2a, the second work area 2b, and the third work area 2c (or the air conditioning in the second work area 2b and the third work area 2c) may be adjusted in the third air conditioning adjustment step.

[0173] In the above embodiment, the construction method for building 1 has been described as including the first construction section construction process, the first construction section second construction process, the first air conditioning adjustment process, the first construction section third construction process, the second air conditioning adjustment process, the second construction section third construction process, the third air conditioning adjustment process, the third construction section construction process, and the finishing process, but is not limited to this. For example, in addition to these processes, a reinforcement process may be included.

[0174] Here, the reinforcement process is a process of installing reinforcing materials (for example, well-known building reinforcing materials (for example, building brace materials, etc.)) on the first ground structure 10 to reinforce the first ground structure 10 before the second advance construction process.

[0175] As an example, before the construction process of the second work section of the first work section, at least one reinforcing member may be connected to the column sections 24 or beam sections 25 of the first ground structure 10a (first ground structure 10) on adjacent floors 21 (or adjacent column sections 24 and beam sections 25 on the same floor 21) using fasteners or the like (note that the same applies to the second ground structure 10b before the construction process of the third work section of the first work section).

[0176] By performing such a reinforcing process, when constructing the second ground structure 10, the first ground structure 10 can stably support the second ground structure 10, thereby ensuring safety during construction of the building 1.

[0177] In the above embodiment, the construction section to be constructed first in the construction method for building 1 is described as first construction section 2a, but this is not limited to this. For example, it may be a construction section other than first construction section 2a (for example, second construction section 2b or third construction section 2c).

[0178] In the above embodiment, it has been described that in the first construction section, second construction section construction process, a portion of a portion of the second ground structure 10b is constructed after another portion of a portion of the first ground structure 10a has been constructed (i.e., during the first construction process), but this is not limited to this. For example, a portion of a portion of the second ground structure 10b (or the entire portion) may be constructed after another portion of the first ground structure 10a has been constructed (i.e., after the first construction process) (note that the same applies to the construction of a portion of a portion of the third ground structure 10c in the first construction section, third construction section construction process).

[0179] Furthermore, in the above embodiment, it was explained that the entire portion of the second ground structure 10b is constructed after the construction process of the second construction section of the first construction area and the construction process of the third construction section of the first construction area, but this is not limited to this, and it may be constructed, for example, after the construction process of the second construction section of the first construction area.

[0180] Furthermore, in the above embodiment, it was explained that the entire portion of the third ground structure 10c is constructed after the construction process of the third section of the first construction area and the construction process of the third section of the second construction area, but this is not limited to this, and it may be constructed, for example, after the construction process of the third section of the first construction area.

[0181] (Addendum) The building construction method of Appendix 1 is a construction method for dividing a building into multiple construction sections and constructing it, and includes: a first construction process for constructing a first ground structure that constitutes the building in a first construction section; a second advance construction process for constructing a second ground structure that constitutes the building in a second construction section adjacent to the first construction section after or during the first construction process, while supporting the first ground structure on a portion of the second ground structure that comprises at least an exterior wall portion; and a second subsequent construction process for constructing another portion of the second ground structure while supporting the other portion on the first ground structure after the second advance construction process.

[0182] The building construction method of Supplementary Note 2 is the building construction method of Supplementary Note 1, wherein in the second advance construction process, the portion including the exterior wall portion and roof portion of the second above-ground structure is constructed.

[0183] The building construction method of Supplementary Note 3 is the building construction method of Supplementary Note 2, which includes, after the second preceding construction process, an air conditioning adjustment process of adjusting the air conditioning in at least the second construction area.

[0184] The building construction method of Appendix 4 is a building construction method described in any one of Appendixes 1 to 3, in which the exterior wall portion of the second ground structure is connected to the column or beam portion of the second ground structure via exterior wall support material and base member, and the base member comprises a support beam material and a furring strip material connecting the exterior wall support material and the support beam material, and the support beam material and the furring strip material are each made of H-beam steel.

[0185] The building construction method of Supplementary Note 5 is the building construction method of Supplementary Note 4, wherein the base member is provided with a position adjustment portion for adjusting the horizontal position of the furring strip material.

[0186] The building construction method of Appendix 6 is a building construction method described in any one of Appendixes 1 to 3, which includes a reinforcement step of providing reinforcing material to the first ground structure before the second advance construction step.

[0187] (Effect of supplementary notes) The building construction method described in Appendix 1 includes a second preceding construction process in which, after or during the first construction process, a portion of the second ground structure, including at least the exterior wall portion, is constructed in the second construction section while the portion is supported on the first ground structure, and a second following construction process in which, after the second preceding construction process, another portion of the second ground structure is constructed while the other portion is supported on the first ground structure. Therefore, when constructing the second ground structure after or during the construction of the first ground structure, the second ground structure can be supported on the first ground structure, eliminating the need for temporary members, thereby improving the ease of construction of the building. Furthermore, by constructing the portion of the second ground structure, including the exterior wall portion, in advance, the impact of wind can be reduced when constructing the other portion of the second ground structure, thereby avoiding delays in the construction of the building.

[0188] According to the building construction method described in Appendix 2, in the second advance construction process, a portion of the second ground structure including the exterior wall and roof portions is constructed. By constructing a portion of the second ground structure in advance, the effects of wind and weather can be reduced when constructing other portions of the second ground structure, making it possible to further avoid delays in the construction of the building.

[0189] According to the building construction method described in Appendix 3, an air conditioning adjustment process for adjusting the air conditioning in at least the second construction area is included after the second advance construction process, so that the air conditioning in at least the second construction area can be adjusted and various processes carried out in at least the second construction area after the air conditioning adjustment process can be carried out comfortably.

[0190] According to the building construction method described in Appendix 4, the exterior wall portion of the second ground structure is connected to the column portion or beam portion of the second ground structure via exterior wall support material and base member, and the base member comprises a support beam material and a furring strip material, and the support beam material and the furring strip material are each made of H-steel material, so the support beam material and the furring strip material can be manufactured easily and inexpensively, and the manufacturability of the base member can be improved.

[0191] According to the building construction method described in Appendix 5, the base material is equipped with a position adjustment section, which makes it possible to easily adjust the horizontal position of the furring strip material, thereby improving the ease of installation of the base material.

[0192] According to the building construction method described in Appendix 6, a reinforcement process of installing reinforcing materials on the first ground structure is included before the second preliminary construction process, so that when the second ground structure is constructed, the first ground structure can stably support the second ground structure, ensuring safety during the construction of the building.
