508395 五、發明說明（1) 發明背景： 目前一般橋柱接頭，主要之施工法均採場铸之方式實 施，然其場鑄之施工法則存有許多之缺點，如：1、施工 時間過長易導致工程之延誤及交通之阻塞，2、成本過 高，3、品質不易控制，4、施工時會受現場場地之限制 等，而採場鑄施工法之橋柱接頭雖有上列之各種缺點，然 仍被延用至今，其主要之原因在於若採預鑄之方式雖無上 述之問題存在，但其整體之安全性（如能量消散能力、動 性值等）卻大幅降低，因此若能有一全新之裝置或工法能 擺脫場鑄之缺點，且又無安全危害之虞者，將能大幅提高 整體之施工品質者。 發明目的： 本發明之主要目的在於透過一種耐震橋柱塑鉸區預鑄 接頭之實施，可廣泛應用於橋梁結構之鋼筋混凝土橋柱， v 且可採預鑄之方式取代場鑄之施工法，除無場鑄之各項缺 點外亦無安全上之危害，且可適用於各種中空斷面（如， 矩形柱、圓形柱、不規則形狀柱）之鋼筋混凝土橋柱上 者。 詳細說明： 以下特列舉一實施例，以詳細說明本發明之作用、構 造與特徵： 請參閱第一、二圖所示係基座模板組及混凝土灌製示508395 V. Description of the invention (1) Background of the invention: At present, the main construction methods of bridge and column joints are implemented by field casting. However, the construction method of field casting has many disadvantages, such as: 1. The construction time is too long. It is easy to cause engineering delays and traffic blockages. 2. The cost is too high. 3. The quality is not easy to control. 4. The construction site will be restricted by the site and so on. Disadvantages, however, are still being used till now. The main reason is that if the method of mining is not as described above, the overall safety (such as energy dissipation capacity, kinetic value, etc.) is greatly reduced. Therefore, if Those who can have a brand-new device or method that can get rid of the shortcomings of field casting without the risk of safety hazards will greatly improve the overall construction quality. Purpose of the invention: The main purpose of the present invention is to implement a reinforced concrete bridge column of a bridge structure through the implementation of a plastic joint in a hinged area of an earthquake-resistant bridge column. In addition to the shortcomings of field casting, there is no safety hazard, and it can be applied to reinforced concrete bridge pillars of various hollow sections (such as rectangular columns, circular columns, and irregularly shaped columns). Detailed description: An example is given below to explain the function, structure and features of the present invention in detail: Please refer to the base formwork group and concrete pouring instructions shown in the first and second figures
