【発明の詳細な説明】 [産業上の利用分野] 本発明は、木造住宅等建物の各階層間又は階層と屋根
層間の上下連結装置に係り、特に耐振破壊防止用上下連
結装置に関する。Description: TECHNICAL FIELD The present invention relates to a vertical coupling device between floors of a building such as a wooden house or between a floor and a roof layer, and particularly to a vertical coupling device for preventing vibration damage.
[従来の技術] 建物の各階層又は階層と屋根層とは、梁、桁或いは根
太等の構造材で上下層に画されているが、これら構造材
は上下両層の柱や耐力壁等を連結した上下層共通の構造
材であるため、従来建物は、最下階層から屋根層に及ん
で上記梁、桁、柱等を一体的に連結したフレーム全体と
しての強度を有している。[Prior Art] Each floor or floor of a building and the roof layer are separated into upper and lower layers by structural materials such as beams, girders or joists. These structural materials have columns and bearing walls of both upper and lower layers. Since it is a structural material common to the upper and lower layers that are connected, the conventional building has the strength of the entire frame in which the beams, girders, columns, and the like are integrally connected from the lowest floor to the roof layer.
しかし、かかる従来建物は全体構造が剛で層間変位が
許されないから、地震や強風によって各層に不均一且つ
過大な衝撃力が加わると、上記梁等と通し柱や管柱の接
合部などの上下層の連結部分に力が集中して破壊に至る
可能性があった。However, since the conventional structure has a rigid overall structure and displacement between layers is not allowed, if an uneven and excessive impact force is applied to each layer due to an earthquake or strong wind, the upper and lower layers such as the joint between the beam and the through column or tube column will be There was a possibility that the power would be concentrated on the connecting part of and lead to destruction.

案されている。This point can be pointed out for new buildings, of course, but especially when the roof layer of the existing building or only the roof layer and the upper layer is removed and a new renovation is performed, it is difficult to use through columns and the age of both upper and lower layers Since the degree of deterioration is greatly different, for example, the impact force that the upper layer, which is superior in strength, withstands deformation and transmits,
In fact, there is a possibility of causing damage to the connecting portion with the lower layer, which is actually inferior in strength, and it is necessary to further consider the strength resistance of the connecting portion between these upper and lower layers. Further, in order to prevent the vibration applied to the foundation from being transmitted to the upper structure, a cushion body having an elastic body interposed between a plurality of opposing hard plates is prepared, and one cushion body is provided between the foundation and the foundation or the pillar. An earthquake-proof structure for a house with the above intervention is proposed as Japanese Patent Laid-Open No. 52-75036.

がある。However, since the upper and lower hard plates are not connected to each other by members other than the elastic body so as to be movable in the height direction and the horizontal direction and with a space therebetween, the elastic body deteriorates and loses its elasticity. Then, the space between the upper and lower hard plates is narrowed to incline the building, or the upper and lower hard plates are separated, and as a result, the building may be seriously damaged before the deteriorated cushion body is replaced.

される建物の免震構造としては不適当なものである。However, this is a pedestal on which a computer or the like is placed, and is completely different in its use and basic technical idea from the invention of the present application, which is a connecting device between each layer in a building, and has a spring having elasticity. In addition to the members, there is no member for firmly connecting the floor and the base to the displacement in the height direction and the horizontal direction and maintaining a gap therebetween, and therefore the spring member deteriorates. When it becomes brittle, the connection between the floor and the base becomes very unstable, which makes it unsuitable as a seismic isolation structure for buildings that require a high degree of safety.
従って、これらの従来技術は、通し柱を設けること無

As a result, it is possible to expand and reconstruct the upper layer without through columns, which was almost impossible in the past, and the building is not damaged seriously even if the elasticity of the shock absorber is lost. The purpose is to provide a device.

On the other hand, the shock absorber, which is elastically interposed between the upper and lower structural members, elastically deforms when the force applied non-uniformly to the upper and lower layers is transmitted to the other layers, prolongs the action time of the transmitted force and impacts it. It not only relaxes it, but also transforms the energy of vibration to a part of heat during deformation and reduces it. The connecting arm connects the upper and lower structural members while keeping a space therebetween, and further follows the shearing force without damaging the absorption of the vibration by the shock absorbing device at some vibrations. Further, the exterior material shields the gap between the layers.

いられるべきである。On the other hand, the shock absorber may employ a coil spring, a natural or synthetic rubber, a honeycomb core made of an aluminum alloy, or the like, in addition to the leaf spring and the foamed resin. Among the foamed resins, urethane foamed resins are particularly excellent in elasticity and water resistance, but other urea foams and phenol foams can be adopted, and the latter is particularly advantageous. Since the foamed styrene resin and the vinyl chloride foam are relatively weak to heat, they should be used so that the temperature rise can be suppressed within the safe range by the exterior material.

る。It is also possible to construct the shock absorber with an elastic adhesive. Various types of elastic adhesives are provided, for example, as a combination of a main component of a special silicone and a modified polymer, or a main component of an epoxy resin and a curing agent of a special silicone and a modified polymer. If a structural frame like a foamed resin is filled and the two structural materials are bonded together, the elastic adhesive, which is initially a viscous liquid, becomes a rubber-like elastic body after solidification, and receives the load of the upper layer between the upper and lower structural materials. And the upper and lower layers are connected by the adhesive force.

る。[Curing of the Invention] The present invention is configured as in the above-mentioned gist, and the structural members that demarcate each layer or the layer and the roof layer are double-layered separately for the upper and lower layers, and a shock absorber is provided between the upper and lower structural members. Since the upper and lower layers are connected elastically, the upper and lower layers are individually resistant to each other due to the structural materials arranged separately, and each structure can be kept strong against earthquakes and strong winds. At the same time, since the interlayer displacement is allowed elastically between the upper and lower layers by the shock absorber, it is possible to extend the action time of the impact force transmitted between the upper and lower layers and to alleviate the impact force. Since the force transmitted and transmitted is received by the structural materials having strong resistance to both the upper and lower layers, the upper and lower layers and the shock absorber are installed for the vibration accompanying the shock such as an earthquake or strong wind. Effective structural destruction at any part of the lower connecting part Can be prevented. As a result, it is possible to add or renovate the upper layer that is not connected by through columns, which has been almost impossible in the past, and it is possible to cope with various renovation plans. Further, even if the elasticity of the shock absorber is lost due to aging or the like, the upper and lower structural members are connected by the connecting arms so as to maintain a space and follow the displacement in the height direction and the horizontal direction, so that the upper and lower structures are connected. The space between them will not be uneven, and the building will not tilt, and the horizontal deformation between the upper and lower layers will not become too large. Since it follows the movement in the height direction and the horizontal direction, there is no risk of damaging the vibration absorption by the shock absorber or damaging it. In addition, it is possible to cover each interlayer gap and the shock absorber by an exterior material arranged on the outer periphery of each interlayer gap, and to obtain a harmony of the entire appearance in a building in which such upper and lower interlayer displacement is allowed. .
