Description of the Related Art As a technique for protecting a building from disturbances such as winds and earthquakes, a technique for structuring a building using a viscoelastic damper has recently been adopted. The viscoelastic damper used in this building's vibration damping structuring technology has a laminated structure of a metal plate and a viscoelastic resin, and absorbs the energy of displacement between the metal plates using the characteristics of the viscoelastic resin. By doing so, a vibration damping function is obtained. In the manufacturing process of such a viscoelastic damper, a plurality of metal plates and a layer of a viscoelastic resin are laminated,
After forming the main body of the viscoelastic damper, heat treatment is performed to cure the viscoelastic resin to obtain appropriate viscoelastic characteristics. For this heat treatment, an air atmosphere furnace or a steam heating furnace used for heat treatment of general resin products has been used.

められている。In recent years, this viscoelastic damper has been actively employed in larger buildings.
Accordingly, many larger viscoelastic dampers having a weight of 500 kg or more have been used. When a general air atmosphere furnace or a steam heating furnace is used to perform heat treatment on such a large molded product, the product is heated to a desired temperature as compared with the case where heat treatment is performed on a conventional small molded product. More time is needed. In order to mass-produce large viscoelastic dampers, a heat treatment apparatus capable of heating a large molded product in a short time is required.

た。Further, in order to heat-treat such a large-sized product on a large scale on an industrial scale, a steam heating furnace using steam heated by a boiler is advantageous in that energy cost is lower than that of electric heating. It is. However, in the heat treatment of the viscoelastic damper, it is necessary to heat the viscoelastic resin at a temperature of about 70 degrees in order to cure the viscoelastic resin with an appropriate hardness and obtain sufficient viscoelastic properties. In a normal steam heating furnace, the temperature of steam is 100 ° C. or more at normal pressure, and the temperature is too high.

処理方法において、上記成形品を積層構造の層面と概略
垂直となる側面より熱伝導により加熱することである。According to a first aspect of the present invention, there is provided a method for heat treating a molded article having a laminated structure of a metal layer such as a viscoelastic damper and a resin layer, wherein the molded article is substantially perpendicular to the layer surface of the laminated structure. Heating from the side by heat conduction.

The molded article can be heated to a desired temperature in a shorter time.

全体が速やかに均一な温度で加熱されることになる。In a molded article having a laminated structure of a metal layer and a resin layer such as a viscoelastic damper, there is a large difference in thermal conductivity between the metal layer and the resin layer. Therefore, in this means, a molded article having a laminated structure of a metal layer and a resin layer is thermally conductively heated from a side surface substantially perpendicular to the layer surface of the laminated structure. In this case, each metal layer constituting the laminated structure is heated from the end by heat conduction. Thus, the applied heat is quickly transmitted to the entire molded article through each layer of the metal layer having high thermal conductivity, and the entire molded article is quickly heated at a uniform temperature.

粘弾性特性がばらつくようなおそれが少なくなる。The present invention is particularly suitable for heat treatment of a viscoelastic damper which is a large molded product in which a temperature difference easily occurs during heating. According to the present invention, since the entire molded article is heated at a temperature nearly uniform, the curing of the viscoelastic thermal resin by heat treatment proceeds uniformly throughout the viscoelastic damper, and the viscoelastic properties of the resin vary from place to place. Risk is reduced.

置を熱処理炉に備えることができる。As an invention of a heat treatment furnace suitable for heat-treating a molded article as described above, a high-temperature member for heating a molded article to be heated, and a heat-conductive member for transferring the high-temperature member to the molded article to be heated. The heat treatment furnace may be provided with a driving device for moving the contact so as to be separated from the heat treatment furnace.

ることが可能である。In the heat treatment furnace of the present invention, the high-temperature member is heated in advance before the molded article is put into the heat treatment furnace, and after the molded article is put into the furnace, the high-temperature member is moved to contact the molded article with heat. By doing so, the molded article can be heated quickly. In particular, if a high-temperature member having a large heat capacity is used and the temperature is set slightly higher than the target temperature for heating the molded article, the molded article can be heated in a short time with a sufficient amount of heat.

ュートが生じる。In the case of heating a molded article by heat conduction, a mechanism for moving a high-temperature member as in the present invention is not used.
For example, it is also possible to adopt a method in which a heat source such as an electric heater is always kept in contact with the molded product, and the temperature is controlled by turning on and off the electricity. However, in such a method, it takes a considerable time for the temperature of the electric heater itself to rise, and since the output of the electric heater is limited, it takes a long time to heat the molded article. If the temperature of the molded article is to be raised quickly, the temperature of the electric heater must be higher than the temperature of the molded article. In such a case, heating will continue for a while after the electric heater is turned off. In addition, an overshoot occurs in which the ultimate temperature of the molded product becomes higher than the target.

ない。According to the present invention, the heat conduction to the molded article can be instantaneously interrupted by moving the high temperature member so as to thermally contact and separate the molded article. Thereby, the heating of the molded article can be quickly and reliably controlled, and if the high-temperature member is immediately separated when the molded article reaches a desired temperature, there is no possibility that the temperature of the molded article will overshoot.

定の温度とすることが容易となる。If a temperature sensor is directly attached to the molded article to be heated to measure the temperature, and the measured value is used to control the contact and separation of the high-temperature member using a control device, the temperature of the molded article can be accurately measured. It becomes possible to control. The temperature of the molded product is directly measured by a temperature sensor, and when the molded product reaches a desired temperature, the driving of the high-temperature member is controlled so as to separate the high-temperature member, thereby allowing the molded product to reach the desired temperature in a short time. After heating, it is easy to keep the temperature constant without overshooting the temperature.

なる。[0016] The heating by steam has a feature that the calorific value is large as compared with the heating by electricity and the energy cost is low by boiler cooking. Therefore, a large heat capacity can be obtained economically, and the high-temperature member can have a large heat capacity. This makes it more suitable for quickly heating a large molded product on an industrial scale. One problem with using steam for heating is that the boiling point of water is 1
Since the temperature is 00 ° C., the temperature of the steam becomes 100 ° C. or more at normal pressure, which is not suitable for heating a viscoelastic damper requiring a heating temperature of about 70 ° C. However, according to the present invention, once the high-temperature member is heated by steam, and the heated high-temperature member is brought into contact with and separated from the molded product by heat conduction, the contact and the separation are performed in accordance with the ultimate temperature of the molded product. By controlling, even if a heat source by steam is used, the molded article can be heated to about 70 degrees to control the temperature.
