Abstract

The purpose of the present invention is to reduce weight in a concrete building having a framework structure in which heat is blocked using an external heat insulation method, without compromising the heat-blocking performance, the ease of construction, etc. An outer wall (W) having a double wall structure is constructed on an open area (α) surrounded by columns (C) and beams (B) of a concrete building (A). The outer wall is configured from a steel structure wall portion (Wa) comprising intermediate columns (4) having a steel structure, and an inner wall portion (Wb) comprising a steel wall base (12-15). The steel structure wall portion has an outer base surface material (6) fixed to the intermediate columns so as to close the open area. The outside surface (1) of the outer base surface material is positioned in the plane of a vertical surface (V) that includes the outside surfaces (10) of the columns and beams. A heat-blocking material (21) and an outer material (22) are constructed using an external attachment heat-blocking method on the outer base surface (1) of the open area, and a heat-blocking material and an outer material are constructed using an external heat-blocking method on the outer base surface (10) of a structure frame area (β). The heat-blocking material and the outer material form a substantially uniform outer heat-blocking layer (G) that is continuous over the entire area of the outside surface of the building.

Description

建築物の外壁構造、断熱構造及び断熱方法Exterior wall structure, heat insulation structure and heat insulation method of buildings
 本発明は、建築物の外壁構造、断熱構造及び断熱方法に関するものであり、より詳細には、異種の断熱工法(外断熱工法及び外張断熱工法)を複合又は併用した複合的断熱工法により軸組構法又はラーメン構法のコンクリート建築物の外壁面全域を断熱することにより、所望の断熱性能を確保しつつコンクリート建築物の軽量化等を図る建築物の外壁構造、断熱構造及び断熱方法に関するものである。 The present invention relates to an outer wall structure, a heat insulating structure, and a heat insulating method of a building, and more specifically, a shaft is formed by a composite heat insulating method in which different types of heat insulating methods (external heat insulating method and external heat insulating method) are combined or used in combination. It is related to the outer wall structure, heat insulation structure and heat insulation method of a building that aims to reduce the weight of the concrete building while ensuring the desired heat insulation performance by insulating the entire outer wall surface of the concrete building of the construction method or ramen construction method. is there.
 一般に、軸組構法又はラーメン構法の鉄筋コンクリート(RC)構造、鉄骨鉄筋コンクリート(SRC)構造又はプレキャスト鉄筋コンクリート(PCa)構造の建築物(以下、「コンクリート建築物」という。)は、RC構造、SRC構造又はPCa構造(以下、「コンクリート構造」という。)の柱、梁、耐力壁、非耐力壁、床スラブ等より構成される。また、建築物の断熱方式として、外断熱工法、内断熱工法、外張断熱工法及び充填断熱工法等が知られている(非特許文献1及び2)。 Generally, a reinforced concrete (RC) structure, a steel-framed reinforced concrete (SRC) structure, or a precast reinforced concrete (PCa) structure (hereinafter referred to as "concrete building") of a frame construction method or a ramen construction method is an RC structure, an SRC structure, or a building. It is composed of pillars, beams, bearing walls, non-bearing walls, floor slabs, etc. of a PCa structure (hereinafter referred to as "concrete structure"). Further, as a heat insulating method for a building, an external heat insulating method, an internal heat insulating method, an external heat insulating method, a filling heat insulating method and the like are known (Non-Patent Documents 1 and 2).
 外断熱工法は、コンクリート建築物の構造躯体の外壁面(屋外側面)に断熱材を密着せしめて建築物の外壁面全域を断熱材で覆い、蓄熱効果を有するコンクリート構造の躯体を断熱層により被覆する断熱方法である。例えば、特許文献1に記載された外断熱工法では、硬質発泡プラスチック板がコンクリート構造の外壁の外側面に密着状態に施工されるとともに、断熱材を被覆する外装材が断熱材の外側に更に施工される。他方、内断熱工法は、蓄熱効果を有するコンクリート構造の躯体の内側(屋内側)に断熱材を施工し、躯体の内側に断熱層を形成する断熱方法である。 In the external insulation method, a heat insulating material is adhered to the outer wall surface (outdoor side surface) of the structural frame of a concrete building, the entire outer wall surface of the building is covered with the heat insulating material, and the concrete structure frame having a heat storage effect is covered with a heat insulating layer. It is a heat insulating method. For example, in the external heat insulating method described in Patent Document 1, a rigid foamed plastic plate is installed in close contact with the outer surface of the outer wall of the concrete structure, and an exterior material covering the heat insulating material is further applied to the outside of the heat insulating material. Will be done. On the other hand, the internal heat insulating method is a heat insulating method in which a heat insulating material is applied to the inside (indoor side) of a skeleton of a concrete structure having a heat storage effect to form a heat insulating layer inside the skeleton.
 内断熱工法は、建築意匠設計の設計自由度、建築工事の施工性、建築物の維持管理等の点で有利である反面、壁体内部に結露(内部結露)が発生し易いという課題や、コンクリート構造の躯体が環境負荷の影響(日射、外気温変化等の影響)を比較的大きく受け、冷暖房効率が低下するといった課題を有する。他方、外断熱工法には、外装材の劣化、建築物の施工性、建築物の維持管理、建築物の耐火性等の点で課題がある反面、構造躯体が環境負荷の影響(日射、外気温変化等の影響)を受け難いことから、住環境の快適性向上や、コンクリート構造の躯体の熱容量を有効利用した冷暖房の効率向上等の点で有利である。一般には、住環境の快適性や、環境負荷軽減等が重視され、断熱性能の点で外断熱工法が内断熱工法よりも優位であると考えられている。 The internal insulation method is advantageous in terms of design freedom in architectural design design, workability of building work, maintenance of buildings, etc., but on the other hand, there is a problem that dew condensation (internal dew condensation) is likely to occur inside the wall body. There is a problem that the skeleton of the concrete structure is relatively greatly affected by the environmental load (effects of solar radiation, changes in outside temperature, etc.), and the cooling and heating efficiency is lowered. On the other hand, the external insulation method has problems in terms of deterioration of exterior materials, workability of buildings, maintenance of buildings, fire resistance of buildings, etc., but the structural frame is affected by environmental load (solar radiation, outside). Since it is not easily affected by changes in temperature, etc.), it is advantageous in terms of improving the comfort of the living environment and improving the efficiency of heating and cooling by effectively utilizing the heat capacity of the concrete structure. In general, the comfort of the living environment and the reduction of the environmental load are emphasized, and it is considered that the external insulation method is superior to the internal insulation method in terms of heat insulation performance.
 このように外断熱工法及び内断熱工法は、構造躯体の熱容量と機能的又は構造的に密接に関連した断熱方法であり、熱容量が大きい外壁(即ち、コンクリート構造の外壁)を有するコンクート建築物特有の断熱方法として知られているが、これに対し、このように熱容量が大きい外壁を備えない建築物、即ち、鉄骨構造又は木構造の建築物の断熱方法として、外張断熱工法及び充填断熱工法が知られている。 As described above, the external heat insulating method and the internal heat insulating method are heat insulating methods that are functionally or structurally closely related to the heat capacity of the structural frame, and are peculiar to a concrete building having an outer wall having a large heat capacity (that is, an outer wall of a concrete structure). In contrast to this, the external insulation method and the filling insulation method are known as insulation methods for buildings that do not have an outer wall with a large heat capacity, that is, steel-framed or wooden structures. It has been known.
 外張断熱工法は、鋼構造又は木構造の軸組の外側に断熱材を施工し、建築物の外壁面全体を断熱材で覆う断熱方法である。例えば、特許文献2に記載された外張断熱工法では、鉄骨構造又は木構造の柱の外側に断熱材及び通気胴縁が施工されるとともに、ALCパネル等の外装材が通気胴縁の外側に施工される。また、特許文献3に記載された外張断熱工法によれば、木構造又は鉄骨構造の柱の外側に支持部材及び断熱材が施工されるとともに、外装材を支持する取付具が支持部材に固定され、窯業系又は金属系サイディング等の軽量な外装材が取付具を介して支持部材に支持される。他方、充填断熱工法は、鉄骨構造又は木構造の骨組内中空域(隣合う間柱の間(又は、間柱及び端柱の間)の空間)に断熱材を充填する断熱方法である。 The external insulation method is a heat insulation method in which a heat insulating material is applied to the outside of the frame of a steel structure or a wooden structure, and the entire outer wall surface of the building is covered with the heat insulating material. For example, in the external heat insulating method described in Patent Document 2, a heat insulating material and a ventilation furring strip are installed on the outside of columns of a steel structure or a wooden structure, and an exterior material such as an ALC panel is placed on the outside of the ventilation furring strip. It will be constructed. Further, according to the external heat insulating method described in Patent Document 3, a support member and a heat insulating material are installed on the outside of columns of a wooden structure or a steel frame structure, and a fixture for supporting the exterior material is fixed to the support member. A lightweight exterior material such as a ceramic or metal siding is supported by the support member via a fixture. On the other hand, the filling insulation method is an insulation method in which a heat insulating material is filled in a hollow area (or a space between adjacent studs (or between studs and end columns)) in a steel frame structure or a wooden structure.

 軸組構法又はラーメン構法のコンクリート建築物の耐震性能は、基本的には、軸組の耐震強度に依存するが、コンクリート建築物は、自重が極めて大きく、建築物に作用する地震荷重は、木造建築物や鋼構造建築物に比べて極めて大きい。このため、コンクリート建築物の構造設計においては、地震力を少なくとも部分的に負担する適当な壁量の耐力壁(耐震壁)を建築物の適所に配置した設計が一般に採用される。他方、耐力壁を有する建築物の構造計画においては、耐力壁の配置と関連した建築物の偏心率を制限しなければならないことから、多くの建築物では、コンクリート構造の非耐力壁の剛性によって建築物の偏心量が増大するのを防止すべく、非耐力壁に構造スリットを形成する必要が生じる。 The seismic performance of concrete buildings using the framework construction method or rigid frame construction method basically depends on the seismic strength of the framework, but concrete buildings have extremely heavy weights, and the seismic load acting on the buildings is wooden. Extremely large compared to buildings and steel structures. For this reason, in the structural design of a concrete building, a design in which a bearing wall (seismic wall) having an appropriate amount of wall that bears at least a partial seismic force is arranged at an appropriate position in the building is generally adopted. On the other hand, in the structural planning of buildings with bearing walls, the eccentricity of the building related to the arrangement of the bearing walls must be limited, so in many buildings, the rigidity of the non-bearing walls of the concrete structure is used. In order to prevent the amount of eccentricity of the building from increasing, it becomes necessary to form a structural slit in the non-bearing wall.
 これに対し、コンクリート構造の躯体を部分的に鋼構造の躯体に設計変更した場合、建築物の自重が比較的大きく軽減し、これに伴って地震荷重が軽減するので、構造的に極めて有利である。例えば、コンクリート建築物の外壁を鋼構造の外壁に設計変更した場合、コンクリート構造の柱及び梁に作用する地震荷重が比較的大きく軽減するので、耐力壁に依存せず、ラーメン構造の軸組の耐震強度のみに依存した構造設計を採用し、或いは、柱・梁の部材断面の縮小、鉄筋本数の低減等を図ることが可能となると考えられる。しかも、鋼構造の外壁は、乾式工法の構造体であるので、現場打ちコンクリートで施工されるコンクリート構造の外壁に比べ、工期短縮、施工性改善等を図る上で実務的に有利である。 On the other hand, when the concrete structure skeleton is partially redesigned to a steel structure skeleton, the weight of the building is relatively greatly reduced, and the seismic load is reduced accordingly, which is extremely structurally advantageous. is there. For example, when the outer wall of a concrete building is redesigned to an outer wall of a steel structure, the seismic load acting on the columns and beams of the concrete structure is relatively greatly reduced, so the frame of the ramen structure does not depend on the bearing wall. It is considered possible to adopt a structural design that depends only on the seismic strength, or to reduce the cross section of columns and beams and reduce the number of reinforcing bars. Moreover, since the outer wall of the steel structure is a structure of the dry construction method, it is practically advantageous in shortening the construction period and improving the workability as compared with the outer wall of the concrete structure constructed by cast-in-place concrete.
 また、コンクリート建築物に関し、必ずしもコンクリート構造の全外壁を鋼構造の外壁として設計しなくとも、非耐力壁として設計すべきコンクリート構造の外壁を鋼構造の外壁に設計変更するだけであっても、建築物をかなり軽量化することができ、しかも、構造スリットをコンクリート構造の非耐力壁に形成するための付加的な工事又は作業工程が不要となる。このような建築物の軽量化や、構造スリットの施工の省略は、建設コスト削減及び工期短縮等を図る上で実務上極めて有益である。 In addition, regarding concrete buildings, even if the entire outer wall of the concrete structure is not necessarily designed as the outer wall of the steel structure, and the outer wall of the concrete structure that should be designed as the non-bearing wall is simply redesigned to the outer wall of the steel structure, The weight of the building can be considerably reduced, and no additional construction or work process is required to form the structural slits in the non-bearing wall of the concrete structure. Such weight reduction of buildings and omission of construction of structural slits are extremely beneficial in practice in order to reduce construction costs and shorten construction periods.
 しかしながら、外断熱工法は、コンクリート構造の躯体の蓄熱作用及びその影響と密接に関連した断熱方法であり、コンクリート構造の躯体に密着した断熱材の存在を前提としたものと考えられているのに対し、鋼構造の外壁は、躯体の蓄熱作用と直接に関係せず、しかも、建築納まり詳細が全く相違する異種の断熱法、即ち、外張断熱工法を採用すべき建築要素である。このような事情より、外断熱工法を採用したコンクリート建築物において鋼構造の外壁を併用又は複合した構成を有する建築構造は知られていない。 However, the external heat insulation method is a heat insulation method closely related to the heat storage action of the concrete structure skeleton and its influence, and is considered to be premised on the existence of a heat insulating material in close contact with the concrete structure skeleton. On the other hand, the outer wall of the steel structure is a building element that should adopt a different type of heat insulation method, that is, an external heat insulation method, which is not directly related to the heat storage action of the skeleton and has completely different building details. Under these circumstances, there is no known building structure having a structure in which an outer wall of a steel structure is used in combination or a composite in a concrete building adopting the external heat insulation method.
 また、中高層階の外壁面に作用する風圧又は地震力の影響(外壁の変形又は挙動等)、壁体の耐火性及び遮音性の低下、外断熱工法及び外張断熱工法における断熱材及び外装材の支持構造及び施工方法の相違等を考慮すると、外断熱工法のコンクリート建築物において鋼構造の外壁を併用又は複合することは、実務的に想定し難い。 In addition, the influence of wind pressure or seismic force acting on the outer wall surface of the middle and upper floors (deformation or behavior of the outer wall, etc.), deterioration of fire resistance and sound insulation of the wall body, heat insulating material and exterior material in the external heat insulating method and the external heat insulating method. Considering the differences in the support structure and construction method, it is difficult to imagine in practice that the outer wall of the steel structure is used together or combined in the concrete building of the external insulation method.
 本発明は、このような事情に鑑みてなされたものであり、その目的とするところは、外断熱工法により断熱される軸組構法又はラーメン構法のコンクリート建築物をその断熱性能を損なうことなく軽量化するとともに、中高層階の外壁面に作用する風圧又は地震力の影響、壁体の耐火性及び遮音性等の低下、異種の断熱工法における断熱材及び外装材の支持構造及び施工方法の相違等の諸課題を克服し得る建築物の外壁構造、断熱構造及び断熱方法を提供することにある。 The present invention has been made in view of such circumstances, and an object of the present invention is to make a concrete building of a frame construction method or a ramen construction method, which is insulated by an external heat insulation method, lightweight without impairing its heat insulation performance. As a result, the influence of wind pressure or seismic force acting on the outer wall surface of the middle and upper floors, deterioration of fire resistance and sound insulation of the wall body, differences in the support structure and construction method of heat insulating materials and exterior materials in different types of heat insulating methods, etc. It is an object of the present invention to provide an outer wall structure, a heat insulating structure, and a heat insulating method of a building that can overcome the various problems.
 上記目的を達成すべく、本発明は、コンクリート構造の柱(C)及び梁(B)より構成される軸組構造のコンクリート建築物(A)に設けられ、建築物の外縁部又は外周部の柱及び梁の屋外側に断熱層が配置された建築物の外壁構造において、
 建築物の外壁構造は、前記柱及び梁より構成される構造躯体領域(β)と、該柱及び梁に囲まれた開口領域(α)とを含み、
 該開口領域には、鋼構造の間柱(4)を備えた鋼構造壁部分(Wa)と、該鋼構造壁部分から屋内側に間隔を隔てて配置された鋼製壁下地の内装壁部分(Wb)とが、二重壁構造の外壁(W)として設けられており、
 前記鋼構造壁部分は、前記間柱の屋外側に配置され且つ前記開口領域を閉塞するように前記間柱に固定された外装下地面材(6)を有し、該外装下地面材、前記柱及び前記梁の屋外側面は、前記構造躯体領域及び開口領域に連続して延在する実質的に単一又は共通の外装下地面(1,10)を形成し、
 前記外装下地面を被覆する断熱材(21)を前記外装下地面に取付け又は敷設し、該断熱材の屋外側に外装材(22)を施工し、前記構造躯体領域及び開口領域に亘って連続する実質的に均一又は均等な外装断熱層(G)を前記柱、梁及び鋼構造壁部分の屋外側に形成することを特徴とする建築物の外壁構造を提供する。
In order to achieve the above object, the present invention is provided in a concrete building (A) having a framework structure composed of columns (C) and beams (B) of the concrete structure, and is provided on an outer edge portion or an outer peripheral portion of the building. In the outer wall structure of a building in which a heat insulating layer is arranged on the outdoor side of columns and beams
The outer wall structure of the building includes a structural skeleton region (β) composed of the columns and beams and an opening region (α) surrounded by the columns and beams.
In the opening region, a steel structure wall portion (Wa) provided with steel structure studs (4) and an interior wall portion (interior wall portion) of a steel wall base arranged at intervals from the steel structure wall portion to the indoor side ( Wb) is provided as the outer wall (W) of the double wall structure.
The steel structure wall portion has an exterior base surface material (6) arranged on the outdoor side of the stud and fixed to the stud so as to close the opening region, and the exterior base surface material, the pillar, and the steel structure wall portion. The outdoor side surfaces of the beam form a substantially single or common exterior substrate surface (1,10) that extends continuously into the structural skeleton area and the opening area.
The heat insulating material (21) covering the exterior base surface is attached or laid on the exterior base surface, and the exterior material (22) is installed on the outdoor side of the heat insulating material, and is continuous over the structural skeleton region and the opening region. Provided is an exterior wall structure of a building, characterized in that a substantially uniform or even exterior heat insulating layer (G) is formed on the outdoor side of the column, beam and steel structure wall portion.
 本発明の上記構成によれば、建築物は、柱及び梁が配置された構造躯体領域(β)においては、コンクリート構造体の外断熱工法に従って外断熱され、柱及び梁に囲繞された開口領域(α)においては、鋼構造体の外張断熱工法に従って外張断熱され、従って、建築物は、外断熱工法及び外張断熱工法の複合的工法又はハイブリット工法により全体的に断熱される。 According to the above configuration of the present invention, in the structural skeleton area (β) where columns and beams are arranged, the building is externally insulated according to the external insulation method of the concrete structure, and the opening area surrounded by the columns and beams. In (α), the external insulation is performed according to the external insulation method of the steel structure, and therefore the building is totally insulated by the combined method of the external insulation method and the external insulation method or the hybrid method.
 鋼構造の外壁は、コンクリート構造の外壁に比べ、その約1/5~1/10の自重を有するにすぎず、従って、上記外壁構造を備えた建築物の自重は、比較的大きく軽減する。前述のとおり、建築物に作用する地震荷重は、建築物の自重の軽減に比例して軽減するので、上記外壁構造は、建築物の耐震性を向上する上で極めて有利である。 The outer wall of the steel structure has only about 1/5 to 1/10 of its own weight as compared with the outer wall of the concrete structure. Therefore, the own weight of the building having the outer wall structure is relatively greatly reduced. As described above, the seismic load acting on the building is reduced in proportion to the reduction of the building's own weight, so that the outer wall structure is extremely advantageous in improving the seismic resistance of the building.
 また、鋼構造の外壁は、乾式工法の構造体であるので、現場打ちコンクリートで施工されるコンクリート構造の外壁に比べ、工期短縮、施工性改善等を図る上で実務的に有利である。 In addition, since the outer wall of the steel structure is a structure of the dry construction method, it is practically advantageous in shortening the construction period and improving the workability as compared with the outer wall of the concrete structure constructed by cast-in-place concrete.
 更に、上記外壁構造は、鋼構造壁部分及び内装壁部分を分離した二重壁構造のものであり、鋼構造壁部分及び内装壁部分の離間は、外部環境と室内空間との間の熱伝達経路において熱伝導又は熱伝達を遮断し又は絶縁するように機能するとともに、鋼構造壁部分及び内装壁部分の相対変位を可能にし、鋼構造壁部分の変形又は挙動の影響で内装壁部分が変形又は挙動する現象を防止する。鋼構造壁部分及び内装壁部分の離間は又、固体伝搬振動や、固体伝播音の伝播又は伝搬を遮断し又は絶縁するように機能する。このような二重壁構造の外壁構造によれば、熱架橋による空調負荷の増大や、結露現象等を防止し得るとともに、非耐力壁としての所望の耐火性能(1時間耐火)を比較的容易に確保することができ、しかも、過大な風圧や地震力に起因した鋼構造壁部分の変形又は挙動や、鋼構造壁部分に伝播又は伝搬した固体伝播音及び振動は、鋼構造壁部分及び内装壁部分の離間によって実質的に絶縁されるので、住環境の快適性等を所望の如く確保することができる。 Further, the outer wall structure is a double wall structure in which the steel structure wall portion and the interior wall portion are separated, and the separation between the steel structure wall portion and the interior wall portion is a heat transfer between the external environment and the interior space. It functions to block or insulate heat conduction or heat transfer in the path, and allows relative displacement of the steel structure wall part and the interior wall part, and the interior wall part is deformed due to the deformation or behavior of the steel structure wall part. Or prevent the phenomenon of behavior. The separation of the steel structural wall portion and the interior wall portion also functions to block or insulate the propagation or propagation of solid propagating vibrations and solid propagating sound. According to the outer wall structure of such a double wall structure, it is possible to prevent an increase in air conditioning load due to thermal cross-linking, a dew condensation phenomenon, etc., and it is relatively easy to achieve a desired fire resistance performance (1 hour fire resistance) as a non-bearing wall. In addition, deformation or behavior of the steel structure wall part due to excessive wind pressure or seismic force, and solid propagating sound and vibration propagated or propagated to the steel structure wall part are caused by the steel structure wall part and the interior.

An air layer 23 is formed between the exterior material 22 and the heat insulating material 21.
 断熱材21、外装材22及び空気層23は、複数の柱スパンγ及び複数の階に亘って連続し、従って、建築物Aの外壁面全域に連続的に延びる外装断熱層Gが形成される。外装断熱層Gの厚さ(幅)T3(図3及び図4)は、従来の外断熱工法の断熱層の厚さと同様、50~200mm、好ましくは、75~150mmの範囲内の寸法(本例では約100mm)に設定される。外装断熱層Gは、柱C及び梁Bが配置される領域(即ち、構造躯体領域β)においては、蓄熱効果を有するコンクリート構造の躯体を断熱材で覆う外断熱層を構成し、他方、構造躯体領域βに囲繞された領域(即ち、矩形開口領域α)においては、鋼構造壁部分Waの外側面に断熱材21を施工して鋼構造壁部分Waを断熱材21で覆う外張断熱層を構成する。かくして、建築物Aは、外断熱工法及び外張断熱工法の複合的工法又はハイブリッド工法により建築物Aの外壁面全域を断熱する外装断熱層Gを備える。 The heat insulating material 21, the exterior material 22, and the air layer 23 are continuous over a plurality of column spans γ and a plurality of floors, and thus an exterior heat insulating layer G that continuously extends over the entire outer wall surface of the building A is formed. .. The thickness (width) T3 (FIGS. 3 and 4) of the exterior heat insulating layer G is the same as the thickness of the heat insulating layer of the conventional external heat insulating method, and has dimensions within the range of 50 to 200 mm, preferably 75 to 150 mm (book). In the example, it is set to about 100 mm). In the region where the columns C and the beams B are arranged (that is, the structural skeleton region β), the exterior heat insulating layer G constitutes an external heat insulating layer that covers the skeleton of the concrete structure having a heat storage effect with a heat insulating material, while the structure. In the region surrounded by the skeleton region β (that is, the rectangular opening region α), the heat insulating material 21 is applied to the outer surface of the steel structure wall portion Wa, and the steel structure wall portion Wa is covered with the heat insulating material 21. To configure. Thus, the building A includes an exterior heat insulating layer G that insulates the entire outer wall surface of the building A by a combined construction method or a hybrid construction method of the external heat insulating method and the external heat insulating method.
 外装材22は、矩形開口領域α及び構造躯体領域βの境界において目地幅だけ離間し、外装用のシーリング材(シリコン系、アクリルウレタン系又はポリサルファイド系シーリング材等)を目地空間に充填してなる縦目地40及び横目地41が、矩形開口領域α及び構造躯体領域βの境界に形成される。目地40、41は、地震時、強風時等に生じ得る構造躯体(柱C及び梁B)と鋼構造壁部分Waとの挙動、変位又は変形の相違を補償し又は吸収するワーキングジョイントとして機能する。 The exterior material 22 is separated by the joint width at the boundary between the rectangular opening region α and the structural skeleton region β, and the joint space is filled with an exterior sealing material (silicon-based, acrylic urethane-based, polysulfide-based sealing material, etc.). The vertical joint 40 and the horizontal joint 41 are formed at the boundary between the rectangular opening region α and the structural skeleton region β. The joints 40 and 41 function as working joints that compensate for or absorb differences in behavior, displacement, or deformation between the structural frame (column C and beam B) and the steel structure wall portion Wa that may occur during an earthquake, strong wind, or the like. ..
 このように構成された建築物Aは、外断熱工法及び外張断熱工法の複合的工法により外壁面全体を屋外側から断熱する外装断熱層Gを備えたコンクリート建築物であり、コンクリート建築物特有の断熱方法である外断熱工法と同等の断熱性能が得られるにもかかわらず、コンクリート構造の壁を有しない。鋼構造壁部分Wa及び内装壁部分Wbから構成される建築物Aの外壁Wは、コンクリート構造の外壁の自重に比べ、その約1/5~1/10の自重を有するにすぎないので、建築物Aの自重は、大きく軽減する。建築物Aの柱C及び梁Bの構造躯体に作用する地震荷重(短期水平荷重)は、このような自重の軽減に伴って比較的大きく軽減し、基礎等の構造的負荷も比較的大きく軽減するので、外断熱工法及び外張断熱工法の複合的工法は、建築物Aの構造計画上、極めて有益である。しかも、鋼構造の外壁の採用は、工期短縮、建設コスト低減等を可能にするので、建築物Aの施工計画の観点においても有益である。 The building A configured in this way is a concrete building provided with an exterior heat insulating layer G that insulates the entire outer wall surface from the outdoor side by a combined construction method of the external heat insulating method and the external heat insulating method, and is peculiar to the concrete building. Although it has the same heat insulating performance as the external heat insulating method, which is the heat insulating method of the above, it does not have a concrete structure wall. The outer wall W of the building A composed of the steel structure wall portion Wa and the interior wall portion Wb has a weight of only about 1/5 to 1/10 of the weight of the outer wall of the concrete structure. The weight of the object A is greatly reduced. The seismic load (short-term horizontal load) acting on the structural frame of the columns C and beams B of the building A is relatively greatly reduced with the reduction of its own weight, and the structural load of the foundation etc. is also relatively greatly reduced. Therefore, the combined construction method of the external insulation method and the external insulation method is extremely useful in terms of the structural plan of the building A. Moreover, the adoption of the outer wall of the steel structure makes it possible to shorten the construction period, reduce the construction cost, etc., and is therefore beneficial from the viewpoint of the construction plan of the building A.
 また、鋼構造壁部分Wa及び内装壁部分Wbの内部空間は、建築設備用の配線・配管空間として使用し得るので、建築設備工事の施工性が向上する。それにもかかわらず、外壁Wの壁厚(図3及び図4に示す壁厚[T0+T1+T2])は、150~250mmであり、通常のコンクリート壁と壁厚と同等の壁厚に設計し得るので、有効利用可能な建築空間を室内空間が大きく縮小することはなく、建築意匠設計上の不利は、生じ難い。加えて、鋼構造壁部分Wa及び内装壁部分Wbからなる二重壁構造の外壁Wは、所望の耐火性能(1時間耐火)を比較的容易に確保することができる。 Further, since the internal space of the steel structure wall portion Wa and the interior wall portion Wb can be used as a wiring / piping space for building equipment, the workability of building equipment construction is improved. Nevertheless, the wall thickness of the outer wall W (wall thickness [T0 + T1 + T2] shown in FIGS. 3 and 4) is 150 to 250 mm, and the wall thickness can be designed to be the same as that of a normal concrete wall. The interior space does not significantly reduce the effectively available architectural space, and disadvantages in architectural design design are unlikely to occur. In addition, the outer wall W of the double wall structure composed of the steel structure wall portion Wa and the interior wall portion Wb can relatively easily secure the desired fire resistance performance (fire resistance for 1 hour).
 更に、建築物Aの中高層階の外壁面には、比較的大きな風荷重が作用するが、鋼構造の鋼構造壁部分Waの面外剛性は、この風荷重に耐えるように比較的容易に設計することができる。また、風荷重に起因した鋼構造壁部分Waの変形、挙動又は振動や、外部騒音の固体伝播等は、緩衝帯Sによって吸収又は絶縁されるので、内装壁部分Wbに影響せず、従って、屋内環境の居住性又は快適性等は、損なわれず、また、外界の気象、日射等の変化に起因した熱伝達も又、緩衝帯Sによって確実に絶縁されるので、金属製の骨組2-5、12-15の採用に伴う空調設計上の不利等は生じ難い。 Further, a relatively large wind load acts on the outer wall surface of the middle and upper floors of the building A, and the out-of-plane rigidity of the steel structure wall portion Wa of the steel structure is designed relatively easily to withstand this wind load. can do. Further, deformation, behavior or vibration of the steel structure wall portion Wa due to the wind load, solid propagation of external noise, etc. are absorbed or insulated by the buffer zone S, and therefore do not affect the interior wall portion Wb. Therefore, The comfort or comfort of the indoor environment is not impaired, and heat transfer due to changes in external weather, solar radiation, etc. is also reliably insulated by the buffer zone S, so that the metal frame 2-5 , 12-15 is unlikely to cause any disadvantages in air conditioning design.
 加えて、実質的に連続する鉛直且つ平坦な単一且つ共通の被施工面を構成する外装下地面1、10や、後述する外装材支持機構は、外壁面全域に亘って実質的に同一又は同等の支持構造により断熱材21及び外装材22を施工することを可能にする。 In addition, the exterior base surfaces 1 and 10 constituting a substantially continuous vertical and flat single and common surface to be constructed, and the exterior material support mechanism described later are substantially the same or substantially the same over the entire outer wall surface. The same support structure makes it possible to construct the heat insulating material 21 and the exterior material 22.

 前述の実施形態においては、建築物Aは、耐力壁(耐震壁)を備えず、全ての外壁Wを鋼構造の鋼構造壁部分Waと鋼製壁下地(JASS26又は同等品)の内装壁部分Wbとから構成される乾式二重壁構造の非耐力壁として設計したものであるので、顕著な自重軽減により、比較的大きく地震荷重が軽減するが、その反面、全地震荷重を柱C及び梁Bの軸組が負担しなければならない。柱C及び梁Bの構造的負荷が過大となり得る場合には、図6及び図7に示す建築物A’の如く、コンクリート構造の耐力壁(耐震壁)KWを所望の外壁位置に施工しても良い。このような外壁構造においては、外装下地面10は、柱C及び梁Bのみならず、耐力壁KWにも連続する。外装断熱層Gを構成する断熱材21は、梁B、柱C及び面材6の屋外側面のみならず、耐力壁KWの屋外側面にも配置される。 In the above-described embodiment, the building A is not provided with a bearing wall (seismic wall), and all the outer walls W are made of a steel structure wall portion Wa of a steel structure and an interior wall portion of a steel wall base (JASS26 or equivalent). Since it was designed as a non-bearing wall with a dry double wall structure composed of Wb, the seismic load is relatively significantly reduced due to the remarkable reduction of its own weight, but on the other hand, the total seismic load is applied to the columns C and beams. B's framework must bear. If the structural load of columns C and beams B can be excessive, a concrete bearing wall (seismic wall) KW is installed at the desired outer wall position as shown in Building A'shown in FIGS. 6 and 7. Is also good. In such an outer wall structure, the exterior base surface 10 is continuous not only with the columns C and the beams B but also with the bearing wall KW. The heat insulating material 21 constituting the exterior heat insulating layer G is arranged not only on the outdoor side surface of the beam B, the pillar C and the face material 6, but also on the outdoor side surface of the bearing wall KW.
 断熱材21は、前述の実施形態と同様の施工方法により、外装下地面1、10に面接触又は密着した状態で係留具(図示せず)によって梁B、柱C、鋼構造壁部分Wa及び耐力壁KWに留付けられる。所望により、透湿防水シート(図示せず)が外装下地面1、10に接着され、断熱材21と外装下地面1、10との間に介挿される。変形例として、透湿防水シート(図示せず)を断熱材21の屋外側面に施工することも可能である。所望により、断熱材21を外装下地面1、10に接着しても良い。 The heat insulating material 21 is provided with a beam B, a column C, a steel structure wall portion Wa, and a steel structure wall portion Wa by a mooring tool (not shown) in a state of surface contact or close contact with the exterior base surfaces 1 and 10 by the same construction method as in the above-described embodiment. It is fastened to the bearing wall KW. If desired, a moisture-permeable waterproof sheet (not shown) is adhered to the exterior base surfaces 1 and 10 and inserted between the heat insulating material 21 and the exterior base surfaces 1 and 10. As a modification, it is also possible to install a moisture permeable waterproof sheet (not shown) on the outdoor side surface of the heat insulating material 21. If desired, the heat insulating material 21 may be adhered to the exterior base surfaces 1 and 10.
 外装材22は、前述の実施形態(図3)と同様、固定具24、28、ブラケット25、縦胴縁26及び留付金具27によって間柱4及び端柱5に支持されるとともに、RC用アンカー29、固定具28、ブラケット25、縦胴縁26及び留付金具27によって柱C及び梁Bに固定される。外装材22は又、柱C及び梁Bの支持形態と同じく、RC用アンカー29、固定具28、ブラケット25、縦胴縁26及び留付金具27によって耐力壁KWに固定される。前述の実施形態と同じく、支持機構24~29は、矩形開口領域α及び構造躯体領域βに跨がって外壁全体に一様又は均等に分散する外装材施工用の外装下地を構成する。また、前述の実施形態と同じく、矩形開口領域α及び構造躯体領域βの境界に目地40、41が形成される。目地40、41は、地震時、強風時等に生じ得る外装材22の挙動、変位又は変形の相違を補償する。  The exterior material 22 is supported by the studs 4 and the end columns 5 by the fixtures 24 and 28, the bracket 25, the vertical furring strip 26 and the fastener 27, and is an RC anchor, as in the above-described embodiment (FIG. 3). 29, the fixture 28, the bracket 25, the vertical furring strip 26, and the fastener 27 are fixed to the pillar C and the beam B. The exterior material 22 is also fixed to the bearing wall KW by the RC anchor 29, the fixture 28, the bracket 25, the vertical furring strip 26, and the fastener 27, as in the support form of the pillar C and the beam B. Similar to the above-described embodiment, the support mechanisms 24 to 29 constitute an exterior base material for exterior material construction that is uniformly or evenly dispersed over the entire outer wall across the rectangular opening region α and the structural skeleton region β. Further, as in the above-described embodiment, the joints 40 and 41 are formed at the boundary between the rectangular opening region α and the structural skeleton region β. The joints 40 and 41 compensate for differences in behavior, displacement, or deformation of the exterior material 22 that may occur during an earthquake, strong wind, or the like.
 このようにコンクリート構造の耐力壁KWと、鋼構造の非耐力壁の外壁Wとを併用した建築物A’によれば、建築物A’の軽量化の効果は若干低下するかもしれないが、柱C及び梁Bの構造的負荷の軽減や、建築物A’の耐震性の改善、更には、鉄筋数量の低減等による建設コストの抑制等を図ることが可能となる。 According to the building A'in which the bearing wall KW of the concrete structure and the outer wall W of the non-bearing wall of the steel structure are used in combination in this way, the effect of weight reduction of the building A'may be slightly reduced. It is possible to reduce the structural load of columns C and beams B, improve the earthquake resistance of building A', and further reduce the construction cost by reducing the number of reinforcing bars.

Is fixed to the bracket 25 by the fixture 28. For example, as the vertical furring strip 26', a square steel pipe having a size of 40 × 40 × 1.6 (mm) can be preferably adopted. Similar to the above-described embodiment, the bracket 25 and the vertical furring strip 26'consisting of a support mechanism for attaching the exterior material 22 to the outside of the heat insulating material 21, and the support mechanism includes a rectangular opening region α and a structural skeleton region β. An exterior base material for construction of an exterior material that is uniformly or evenly dispersed over the entire outer wall is constructed. The inner side surface 26a'of the vertical furring strip 26' comes into contact with the outdoor side surface of the heat insulating material 21 and restrains the heat insulating material 21 from the outdoor side. The outdoor interface of the insulation 21 is defined or specified by a number of inner surfaces 26a'as a vertical Va (FIG. 9) substantially parallel to the exterior substrate surface 1. Since the outer wall structure of the present embodiment is substantially the same as the above-described embodiment in other configurations, duplicated description will be omitted.
 図10には、図8に示す外壁構造の応用例として、柱Cの柱形輪郭を建築物Aの外壁面に表出させる形態の外壁構造が示されている。本発明に係る外壁構造は、このように柱形輪郭(及び/又は梁形輪郭)を外壁面に表出せしめる建築意匠設計においても同様に採用することができる。例えば、図10に示すように柱Cが外壁Wに対して相対的に平面視外側に突出する設計においては、柱Cの外面に沿って断熱材21を取付けるとともに、RC用アンカー29、ブラケット25、縦胴縁26’及び留付金具27を柱Cに固定し、外装材22を留付金具27に取付ける施工方法が採用される。また、柱Cの角部においては、縦胴縁26” (例えば、C-75×45×15×1.6(mm)のC型鋼)をブラケット25に固定し、L形断面に成形した外装材22’を縦胴縁26”に固定すれば良い。このような外壁構造は、梁Bの梁形を外壁面に表出させる形態の外壁構造においても、同様に採用し得る。 FIG. 10 shows an outer wall structure in which the pillar-shaped contour of the pillar C is exposed on the outer wall surface of the building A as an application example of the outer wall structure shown in FIG. The outer wall structure according to the present invention can also be similarly adopted in an architectural design in which a pillar-shaped contour (and / or a beam-shaped contour) is exposed on an outer wall surface in this way. For example, in a design in which the pillar C projects outward in a plan view relative to the outer wall W as shown in FIG. 10, the heat insulating material 21 is attached along the outer surface of the pillar C, and the RC anchor 29 and the bracket 25 are attached. A construction method is adopted in which the vertical furring strip 26'and the fastener 27 are fixed to the pillar C, and the exterior material 22 is attached to the fastener 27. Further, at the corners of the pillar C, the vertical furring strip 26 ”(for example, C-shaped steel of C-75 × 45 × 15 × 1.6 (mm)) is fixed to the bracket 25, and the exterior material 22 is formed into an L-shaped cross section. 'Is just fixed to the vertical furring strip 26'. Such an outer wall structure can be similarly adopted in an outer wall structure in which the beam shape of the beam B is exposed on the outer wall surface.
 図8には、壁端部を内装壁部分Wbの屋内側面に突付け、外壁Wと直交する間仕切壁50が示されている。間仕切壁50は、シングルランナ・千鳥間柱工法の軽量間仕切壁である。間仕切壁50の両側には、居室等の建築空間が形成される。間柱を構成するスタッド51は、スペーサ54の交互の配設により、壁芯方向において片側に交互に偏心した千鳥配列に配置され、下部ランナ52と上部ランナ(図示せず)との間に鉛直に建込まれる。また、端柱55は、スペーサ54によって千鳥配列に配置された一対の鋼製スタッド55a、55bによって形成される。間仕切壁50の端部には、下張りシール材19a及び上張りシール材19bからなる目地19と同様の目地59が形成される。このように内装壁部分Wb及び間仕切壁50の双方を軽量間仕切壁(鋼製壁下地(JASS26)の間仕切壁又は同等品)として施工することにより、作業性の改善、或いは、施工の効率化を図ることが可能となる。 FIG. 8 shows a partition wall 50 in which the wall end is abutted against the indoor side surface of the interior wall portion Wb and is orthogonal to the outer wall W. The partition wall 50 is a lightweight partition wall of the single runner / staggered stud construction method. Architectural spaces such as living rooms are formed on both sides of the partition wall 50. The studs 51 that make up the studs are arranged in a staggered arrangement that is alternately eccentric to one side in the wall core direction due to the alternating arrangement of spacers 54, and are arranged vertically between the lower runner 52 and the upper runner (not shown). It will be built. Further, the end column 55 is formed by a pair of steel studs 55a and 55b arranged in a staggered arrangement by a spacer 54. At the end of the partition wall 50, a joint 59 similar to the joint 19 made of the underlay seal material 19a and the upholstery seal material 19b is formed. By constructing both the interior wall portion Wb and the partition wall 50 as lightweight partition walls (partition walls of the steel wall base (JASS26) or equivalent products) in this way, workability can be improved or construction efficiency can be improved. It becomes possible to plan.
