This invention relates to a mold for forming a groove for mounting a joint.

担が増大する欠点があつｆＣ。Conventionally, in reinforced concrete buildings, a continuous rigid frame structure of columns and beams has been the basis of strength and earthquake resistance, and the lower walls of windows between columns and the window earthen walls have been ignored in terms of stress in structural calculations, but in reality During an earthquake, the stress of the wall acts on the column, causing damage to the column. Therefore, as an earthquake-resistant measure, the lower wall of the window must be treated as a beam, and the reinforcing bar in the cross section of the column must be increased by 1ft, which is added to the column foundation. fC has the disadvantage of increasing the overall weight itσ, increasing the diameter and number of foundation piles, increasing the amount of building materials, and increasing the economic burden.

特徴とするものである。In order to solve the above-mentioned drawbacks, the present invention uses special formwork to insulate the walls between the columns and the columns when concrete is poured into the concrete structure, and the walls are made up of beams and one independent wall. This invention relates to a special formwork and a rigging joint for forming a continuous wall by interposing a fitting joint in the gap between a column and a wall, which prevents the vibration of the wall during an earthquake. In order to prevent damage to the pillars due to the stress of the walls absorbed by the Yoai joints, the building structures such as pillars can be constructed using conventional construction methods, with the aim of saving reinforcing bars and concrete materials and simplifying construction. Furthermore, it is characterized by being able to prevent infiltration of the joint, sound insulation, heat insulation, and fire resistance.

顕著な諸効果を奏するものであ−る０The wall insulating fitting joint 4 is assembled and fitted into the groove gap 3 formed by the special formwork 18, and it is inserted and fitted into the groove gap 3! By tightening the long poles 13 and 14, each member is connected as one unit, and the rubber backings 7a and 7b at the outer ends are pressed against the inner surface by the elastic presser plates 10a and 10b, and The tapered surface is in close contact with the inner surface of the groove gap 3, and the groove gap @3 is completely sealed.
Mortar coating finish on the inner and outer surfaces of column l and wall 2 30.30
At the time of installation, the inner and outer surfaces of the fitting joint 4 are jointed with caulking material 31, and the fitting joint 4 makes the wall 2 an independent wall integrated with the beam 32, and the styrofoam plate 5 or rubber The elasticity of the backings 7a and 7b can absorb the vibration of the wall 2 during an earthquake and prevent stress from being applied to the column l. It also has excellent heat resistance and fire resistance, and if the component deteriorates, it can be used as a caulking material 31. Replacement and repair is easy by removing the asbestos covers 17a and 17b and pulling out the long bolts 13. : It has the remarkable effects mentioned above, such as making it possible to create a building structure with sufficient earthquake resistance using conventional construction methods without sacrificing damage, and thus making it possible to plan for a large reduction in construction costs.
