本発明は、既設組積建物と補強鉄筋コンクリート構造体
との接合方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of joining an existing masonry building and a reinforced reinforced concrete structure.
最近、明治、大正期の煉瓦建物を景観保存の立場から建
設地で保存するケースが増えている。Recently, there has been an increase in the number of cases in which brick buildings from the Meiji and Taisho eras are being preserved at their construction sites for the sake of landscape preservation.
特に煉瓦造等の組積構造の場合は耐震性に問題があり、
既設組積建物の内側に鉄筋コンクリート構造等で耐震補
強を行う必要がある。Especially in the case of masonry structures such as brick construction, there are problems with earthquake resistance.
It is necessary to provide seismic reinforcement inside the existing masonry building with a reinforced concrete structure.
こうした場合、既設の組積建物は工学的に妥当な支持地
盤には必ずしも基礎底を選んでいない場合があり、永年
の建物の重みで、ある程度沈下を起している場合が多い
。In such cases, existing masonry buildings may not always have foundations that are suitable for supporting ground from an engineering point of view, and the weight of the building over the years has often caused some degree of subsidence.
このような既設組積建物を耐震補強する場合、新しく補
強した鉄筋コンクリート構造物は既設組積壁に密着して
建るため、既設組積建物の基礎底より深く根切底を設け
るのは難しく、若干の圧密沈下が避けられない場合があ
る。When seismically reinforcing an existing masonry building like this, it is difficult to install a root cut deeper than the foundation of the existing masonry building because the newly reinforced reinforced concrete structure is built in close contact with the existing masonry wall. Some consolidation settlement may be unavoidable.
この場合、地盤改良を行う手段もあるが、既設の基礎が
残い場合は難しい。In this case, there are methods to improve the ground, but this is difficult if the existing foundation remains.
そこで、本補強構造はある程度補強構造物が圧密沈下を
起しても、その補強効果を損わないように工夫して創作
した接合方法である。Therefore, the present reinforced structure is a joining method devised and created so that even if the reinforced structure undergoes consolidation settlement to some extent, its reinforcing effect is not impaired.

仕上げるものである。Hereinafter, the present invention will be described with reference to the accompanying drawings, in which 1 is a masonry wall that requires preservation, 2 is an insulating plate made of plywood or the like provided on the back side of the masonry wall and attached to the masonry wall; 3 is an embedded reinforcement inserted into the masonry wall through the insulating plate; 4 is a short pipe with an oval or rectangular cross section 5 or rectangular 6 and an elongated cross section, which is fitted into the embedded reinforcement; After holding the embedded reinforcement 3 so that a void 7 is secured above it, the necessary reinforcing bars and formwork are arranged, and the tip of the embedded reinforcement 3 is filled with easily removable objects such as styroform, and concrete 8 is formed. After curing, the formwork is dismantled, and easily broken materials such as styro foam are removed. Washers 9 and nuts 10 are screwed onto embedded reinforcing bars 3, and objects such as styro foam are removed. A gap is left at the position where the gap and the superficial barb material 14 meet, and the connecting portion between the gap and the superficial barb material 14 is filled with plywood or the like, and the surface is finished by applying the finishing material 14.

の力は伝達されない。The method of joining an existing masonry building and a reinforced reinforced concrete structure according to the present invention is as described in "-", so that the masonry walls and embedded bars do not move in the vertical direction, and when the reinforced reinforced concrete structure sinks. The two are insulated by an insulating plate attached to the back side of the masonry wall, and even if the back side of the masonry wall is uneven, the reinforced reinforced concrete structure sinks smoothly, and the embedded reinforcement 3 Since the gap 7 is provided between the upper part and the pipe 4, the embedded reinforcing bars do not move downward due to the subsidence of the reinforced reinforced concrete structure, and no vertical force is transmitted to the masonry wall 1.

ものである。In addition, in the event of an earthquake, if the masonry wall 1 is subjected to an action that causes it to collapse out of plane, the tensile force of the embedded reinforcing bars 3 transmits the force to the reinforced reinforced concrete structure to prevent it from falling, and the in-plane force is applied. In response to shear forces, the large size of the embedded reinforcing bars has the effect of transmitting the force of the masonry wall to the reinforced reinforced concrete structure.

It is divided into sections and an insulating plate made of thin corrugated iron plate 13 is inserted between both walls, and the masonry wall 1 and reinforced concrete IJ
- The rear wall 11 is completely integrated and reinforced with concrete.
- The load-bearing wall 12 alone bears the vertical load, and both reinforced concrete walls 11 and 12 act cooperatively against the horizontal force, and the shear force situation of the masonry wall It can be used depending on the situation.
