本発明は、壁柱を市松状に配設した建物に関する。 The present invention relates to a building in which wall columns are arranged in a checkered pattern.
従来、内柱をローコストでなくすことができる建物構造を提供することを目的として、建物の外側構面のみを地震力を負担可能な壁梁及び壁柱によって構成し、当該建物の内部の梁として鉄骨梁と鉄筋コンクリート床とからなる合成小梁を採用して内柱をなくした建物構造が提案されている（特許文献１）。 Conventionally, for the purpose of providing a building structure that can eliminate the inner pillar at low cost, only the outer surface of the building is composed of wall beams and wall pillars that can bear seismic force, and as the beams inside the building. There has been proposed a building structure in which a composite beam composed of a steel beam and a reinforced concrete floor is used to eliminate the inner pillar (Patent Document 1).
この内柱をなくした建物構造は、内柱をなくすことができるものの、壁梁の梁成が高くなって垂れ壁と腰壁が形成されることから、開口部形状が制約されるという問題がある。
また、外壁部には柱型と梁型の突出を少なくすることができるが、天井面には梁型が突出するという問題もある。
さらにまた、全ての構造材が現場打ちのＲＣ造であるので、施工期間が長期化して施工コストが嵩む。
This building structure without the inner pillar can eliminate the inner pillar, but the problem is that the shape of the opening is restricted because the wall beams are so high that the hanging wall and the waist wall are formed. is there.
In addition, the protrusions of the columnar and beam types can be reduced on the outer wall, but there is also a problem that the beam shape protrudes on the ceiling surface.
Furthermore, since all structural materials are on-site RC construction, the construction period is prolonged and construction costs increase.
本発明は、上述した種々の課題を解決するために創作されたもので、高度に省力化して工期短縮を図り建築コストを低減化するとともに、室内に柱型、梁型の突出が少ないフレキシビリティの高い内部空間を有する建物を提供することを目的とするものである。 The present invention was created to solve the various problems described above, and is highly labor-saving to shorten the construction period and reduce the construction cost. The object is to provide a building having a high interior space.

さらにまた、壁柱はプレキャストコンクリート製であること、及び、市松状に配置されて左右に隣接する壁柱が存在せず隣接する壁柱同士の湿式の接合工程を省くことができることから、工期期間を短縮して施工コストを大幅に削減することができ、また、型枠等の廃材を減少して環境負荷を低減することもできる。
According to the first aspect of the present invention, the wall columns are arranged in a checkered pattern, and the lower surfaces of both end portions of the upper floor wall columns are joined to the upper surfaces of the opposite end portions of the adjacent wall columns of the lower floor. Since the through pillar structure with the pillars passed through the both ends of the wall pillar, the beam connected to the upper and lower ends of the wall pillar can be a flat beam. It can be configured as a ramen frame with a seismic wall.
In addition, the flat beam has a structure extending in the outer peripheral direction of the building, and the flat slab is integrally joined to the upper and lower surfaces of the flat beam so as to be approximately the same thickness as the flat beam. The projections of the mold and the beam mold can be reduced, and the degree of freedom in designing the floor plan can be increased, thereby ensuring high flexibility.
Furthermore, since the flat slab is any one of a void slab, a precast concrete slab, and a half precast concrete composite floor slab, the floor weight can be reduced or the construction period can be shortened.
Furthermore, since the wall column is made of precast concrete, and there is no wall column adjacent to the left and right, and the wet joining process between adjacent wall columns can be omitted, the construction period The construction cost can be greatly reduced by shortening the construction cost, and the environmental burden can be reduced by reducing waste materials such as formwork.
請求項２に係る発明によれば、壁柱を幅寸法が異なる複数種類のモジュール化して、各種モジュールを選択して組み合わせることによって、開口幅を任意に調整することができる。
また、柱部の鉄筋の一部を他の鉄筋よりも太径としてフープ筋で拘束する構成にすれば、設計耐力を大きくとる部位において幅が狭い壁柱を多数配置することにより、耐力を増強することができる。反対に設計耐力をさほど大きくとる必要のない部位においては、幅が広い壁柱を配置して広い開口を確保することもできる。要するに、設計条件に合わせて簡易に壁量を調整することが可能である。
According to the invention which concerns on Claim 2, the opening width | variety can be arbitrarily adjusted by making a wall pillar into several types of modules from which a width dimension differs, and selecting and combining various modules.
In addition, if a part of the reinforcing bars in the column part is made thicker than the other reinforcing bars and restrained by the hoop bars, the strength is increased by arranging a large number of narrow wall columns in the part where the design strength is increased. can do. On the other hand, a wide opening can be secured by arranging a wide wall column in a portion where the design proof stress is not required to be so large. In short, it is possible to easily adjust the wall amount according to the design conditions.
請求項３に係る発明によれば、壁柱の外面寄り上・下端部に壁柱外面と面一に立ち上げ・垂下形成された、肋筋が埋設された前記壁柱より薄いプレキャストコンクリート突出部が、扁平梁のハーフプレキャストコンクリート、すなわち捨て型枠兼躯体となり、フラットスラブの型枠上にコンクリートを打設する単一の工程で、フラットスラブコンクリートと一体の扁平梁の現場打設部を造成することが可能であり、独立した扁平梁造成工程を省略でき、この点においても工期期間の短縮に寄与することができる。 According to the invention which concerns on Claim 3, the precast concrete protrusion part thinner than the said wall pillar by which the reinforcement was embedded and it was formed in the upper and lower end part near the outer surface of the wall pillar, and was formed in the flush with the wall pillar outer surface. However, it becomes a half precast concrete of flat beams, that is, a discarded formwork and enclosure, and a flat beam slab integrated with flat slab concrete is created in a single process of placing concrete on a flat slab formwork. In this respect, it is possible to omit an independent flat beam forming step, which also contributes to shortening the construction period.

A protrusion 51 that is thinner than the wall 42, in which 57 and the stirrup 52 are embedded, is erected flush with the outer surface of the wall column 4. In other words, as shown in FIG. 2, the upper end of the column part 41 of the wall pillar 4 on the lower floor is notched, and the corner of the projecting part 53 formed in the notch 44 depending on the lower end of the wall pillar 4 on the floor. The two main bars D35 protruding from the upper ends of the opposing column portions 41 of two adjacent wall columns 4 on the lower floor are fitted into the sleeve 43 of the mechanical joint and grouted. The one wall pillar 4 on the floor and the two adjacent wall pillars 4.4 on the lower floor are joined.
この作業を繰り返して当該階の壁柱４の建て込みと下階の壁柱４との接合を実行する。
この作業によって、壁柱４の両端部において柱部４１が垂直方向に通った通し柱構造を構築していく。
By repeating this work, the wall pillar 4 on the floor is built and the wall pillar 4 on the lower floor is joined.
Through this work, a through-column structure in which the column portion 41 passes in the vertical direction at both ends of the wall column 4 is constructed.
図４を参照して、壁柱４は、縦横筋が配筋された壁部４２と、その両端部に一体的に形成された、主筋及び主筋を拘束するフープ筋が配筋された柱部４１と、からなるプレキャストコンクリート製版である。
柱部４１の複数本の主筋のうち壁柱の厚さ方向中央に位置する２本の主筋は、直径が他の主筋Ｄ１３より太いＤ３５とされ、壁柱４の柱部４１上端、すなわち切欠き４４から突出している（図２参照）。
Referring to FIG. 4, the wall column 4 includes a wall portion 42 in which vertical and horizontal bars are arranged, and a column portion in which main bars and hoop muscles for restraining the main bars are integrally formed at both ends thereof. 41 is a precast concrete plate making.
Of the plurality of main bars of the column 41, the two main bars located at the center in the thickness direction of the wall column are D35 having a diameter larger than that of the other main bars D13, and the upper end of the column 41 of the wall column 4, that is, the notch It protrudes from 44 (refer FIG. 2).
下階の壁柱４の切欠き４４から突出している主筋Ｄ３５は、図５に模式的に示されるように、上下左右に壁柱４が存在しない市松状に配置される当該階の壁柱４の柱部４１の下端部に形成されている機械式継手４３に挿入され、グラウト注入されて縦方向に接合される。
図５をみて分かるように、壁柱４は、横方向には連続しないで間隔を置いて配設されている関係から接合されないので、通常の湿式工法による横方向に並ぶ壁柱４同士の接合工程を省略し得る。
壁部４２は、上述の柱部４１の奥行き寸法である厚さと同厚とされ、Ｄ１３の縦横筋が配筋されている。
このため、建物の外周部には柱型の突出を少なくできる。
As shown schematically in FIG. 5, the main bar D35 protruding from the notch 44 of the wall pillar 4 on the lower floor is arranged in a checkered pattern in which the wall pillar 4 does not exist on the top, bottom, left and right. It is inserted into a mechanical joint 43 formed at the lower end of the column part 41, grouted and joined in the longitudinal direction.
As can be seen from FIG. 5, the wall columns 4 are not joined because they are not continuous in the lateral direction but are spaced apart from each other. Therefore, the wall columns 4 are joined together in the lateral direction by a normal wet method. The process can be omitted.
The wall portion 42 has the same thickness as the thickness dimension of the column portion 41 described above, and the vertical and horizontal stripes of D13 are arranged.
For this reason, columnar protrusions can be reduced on the outer periphery of the building.
なお、この実施例の建物１の壁柱４は、建物外周の隅部の交差する両面の１スパンについては、同一幅の壁柱４を全ての階に配設して耐力を増強しているが、この部分においても通常の市松状に配設することとしても良い。 In addition, the wall pillar 4 of the building 1 of this embodiment is strengthening the proof stress by arranging the wall pillar 4 of the same width on all the floors for one span on both surfaces where the corners of the outer periphery of the building intersect. However, it is good also as arrange | positioning in the normal checkered pattern also in this part.

同じく壁柱４の外面寄り下端部にも、壁柱の全幅にわたって当階の扁平梁の肋筋５８とふかし筋５４が埋設された、壁部４２よりも薄い突出部５３が、壁柱４の外面と面一に垂下形成されている。
≪Flat beam≫
As already mentioned in paragraph 0016, the upper end of the wall 42 of the wall column 4 near the outer surface is embedded with the barb 57 and the braid 52 of the flat beam 5 on the upper floor and is thinner than the wall 42. The part 51 is erected flush with the outer surface of the wall column 4.
Similarly, at the lower end near the outer surface of the wall column 4, a protruding portion 53 thinner than the wall portion 42, in which the barb 58 and the braided line 54 of the flat beam of this floor are embedded over the entire width of the wall column 4, It hangs down from the outer surface.
これらの壁柱４の外面寄り上下端部に形成された突出部５１．５３は、ハーフプレキャストコンクリート扁平梁である。
このハーフプレキャスト扁平梁５１．５３は、後述するようにフラットスラブ６のコンクリートが打設されたとき、捨て型枠兼躯体となって現場打設部５５．５６と一体となって完成した扁平梁５となり、壁柱４とフラットスラブ６と一体化されて建物の外周方向に延びる構造となる。
The protrusions 51.53 formed at the upper and lower end portions near the outer surface of these wall columns 4 are half precast concrete flat beams.

図３を参照して、フラットスラブ６の型枠（図示省略）を仮設し、さらに壁柱４と扁平梁５とフラットスラブの取り合い配筋（図示省略）及びフラットスラブ配筋（図示省略）を行い、ワインディングパイプを設置した後、上記したハーフプレキャストコンクリート扁平梁５１．５３の高さに相当する厚みのコンクリートを打設して、扁平梁５の現場打設部５５．５６とフラットスラブ６を同時に一体的に施工する。
≪Floor≫
The flat slab floor 6 is a void slab having the same thickness as the completed flat beam 5 and is integrally joined to the upper and lower surfaces of the flat beam 5 in the same plane.
Referring to FIG. 3, a formwork (not shown) of flat slab 6 is temporarily installed, and further, wall bar 4, flat beam 5, flat slab joint arrangement (not shown) and flat slab arrangement (not shown). After the installation of the winding pipe, the concrete having a thickness corresponding to the height of the half precast concrete flat beam 51.53 described above is placed, and the on-site placement part 55.56 of the flat beam 5 and the flat slab 6 are placed. At the same time, work together.
本発明においては、図３に示される、肋筋５７．５８及びふかし筋５２．５４が配されている部位を扁平梁５の現場打設部と称し、上記ハーフプレキャスト扁平梁５１．５３と合わせて扁平梁５と称している。
上記のコンクリート打設工程により、壁柱４と扁平梁５が一体化された構造、及び、扁平梁５とフラットスラブ６が一体化された構造を構築する。
扁平梁５とフラットスラブ６は上記構成を備えているため、梁型は柱型と同様に室内空間に突出して現れることがないので、室内空間は建物の使用時に高いフレキシビリティを確保することができる。
In the present invention, the portion where the gluteal reinforcement 57.58 and the stiffening reinforcement 52.54 shown in FIG. 3 are arranged is referred to as an in-situ placement portion of the flat beam 5, and is combined with the half precast flat beam 51.53. This is referred to as a flat beam 5.
By the concrete placing process, a structure in which the wall column 4 and the flat beam 5 are integrated and a structure in which the flat beam 5 and the flat slab 6 are integrated are constructed.
Since the flat beam 5 and the flat slab 6 have the above-described configuration, the beam type does not appear to protrude into the indoor space like the column type, so that the indoor space can ensure high flexibility when the building is used. it can.
≪耐震壁≫
本発明の建物１の外周は、上記した市松状に配設された壁柱４の下階から上階に通る柱部４１と、建物の外周方向に延びる扁平梁５と、市松状に配設された壁柱４とが、耐震壁付ラーメン構造として、十分な耐力を備えることとなる。
≪Seismic wall≫
The outer periphery of the building 1 of the present invention is arranged in a checkered pattern, a column 41 passing from the lower floor to the upper floor of the wall pillar 4 arranged in a checkered pattern, a flat beam 5 extending in the outer peripheral direction of the building, and the checkered pattern. The made wall pillar 4 has sufficient strength as a ramen structure with a seismic wall.
実施例１では、図２、図５に示すように、壁柱４の幅が同一サイズのものを市松状に配設して建物１を構築したが、本実施例では図６に示すように、幅寸法が異なる複数種類のモジュールのプレキャストコンクリート製壁柱４Ａ．４Ｂ．４Ｃ．４Ｄ．４Ｅを予め製作しておいて、各種モジュールを選択して組み合わせて外周壁２を構築する。
このようにすると、その幅がバラエティに富んだ開口を自在に形成することが可能となり、柱型と梁型の突出が少ないフレキシビリティと相俟って意匠設計の自由度を高めることができる。
In the first embodiment, as shown in FIGS. 2 and 5, the building 1 is constructed by arranging the wall pillars 4 having the same width in a checkered pattern, but in this embodiment, as shown in FIG. , Precast concrete wall columns 4A. 4B. 4C. 4D. 4E is manufactured in advance, and the outer peripheral wall 2 is constructed by selecting and combining various modules.
If it does in this way, it will be possible to freely form an opening with a wide variety of widths, and it is possible to increase the degree of freedom in design design in combination with the flexibility with few protrusions of the column type and the beam type.
柱部４１の鉄筋Ｄ３５を壁部の鉄筋より太径としてフープ筋で拘束する構成としたから、設計耐力を大きくとる部位において幅が狭い壁柱、例えば図６の４Ａ．４Ｂを多数配置することにより、耐力を増強することができる。
反対に、設計耐力をさほど大きくとる必要のない部位においては、幅が広い壁柱、例えば図６の４Ｄ．４Ｅを配置して広い開口を確保して開放感のある建物とすることもできる。
Since the reinforcing bar D35 of the column part 41 has a larger diameter than the reinforcing bar of the wall part and is constrained by the hoop bar, a wall column having a narrow width at a portion where the design strength is increased, for example, 4A. By arranging a large number of 4B, the proof stress can be enhanced.
On the other hand, in a portion where the design strength is not required to be so large, a wide wall column such as 4D. 4E can be arranged to secure a wide opening and make the building open.
この実施例は、実施例２の壁柱の幅を変更するものとは異なり、壁柱の幅の異同とは無関係に、柱部４１の幅を大きくすることにより耐力を増強しようとするものである。
例えば図６の壁柱４Ｃの両側の柱部の幅を、破線で示すように異なる寸法にして、通し柱の強度を変更自在とする。
これにより、設計耐力を大きくとる部位において通し柱の幅を広くして必要な強度を確保する。
This embodiment is different from the embodiment in which the width of the wall column is changed, and is intended to enhance the proof stress by increasing the width of the column portion 41 regardless of the difference in the width of the wall column. is there.
For example, the width of the column portions on both sides of the wall column 4C in FIG.
Thereby, the width | variety of a through pillar is widened in the site | part which takes a design yield strength, and required intensity | strength is ensured.
そして、外周偏平梁を全てＰＣａとして壁柱と分離して構築することも可能である（図示省略）。 And it is also possible to construct the outer flat beams separately from the wall columns as PCa (not shown).
