Retard-bonded prestressed tendon tensioning and heating device and heating method
The invention discloses a retard-bonded prestressed tendon tensioning and heating device and heating method. The heating device comprises a plurality of first heating plates used for covering the horizontal plane of a to-be-tensioned member and a plurality of second heating plates used for covering the vertical plane of the to-be-tensioned member; the first heating plates are spliced into a whole through bonding parts; the multiple second heating plates are detachably connected with the vertical surface through clamping and fixing parts; each of the first heating plates and the second heating plates comprises two layers of thermal radiation films; a thermal insulation layer is arranged between the two layers of thermal radiation films; a heating belt is laid on one side, opposite to the thermal insulation layer, of each thermal radiation film. The heating device also has the characteristics of high thermal efficiency, fire prevention, flame retardance, one-way heat transfer, convenience in manufacturing, firmness in connection, high adaptability, capability of performing fixed-length processing according to the size of the member and the like, and can ensure that the tensioning of a retard-bonded prestressed tendon is not influenced under the condition of low temperature, so that the influence of the temperature on the tensioning construction of the retard-bonded prestressed tendon is effectively avoided.
本发明的缓粘结预应力筋张拉升温装置及升温方法，升温装置包括：包括用于覆盖待张拉构件的水平面的多块第一加热板以及用于覆盖待张拉构件的竖直面的多块第二加热板，多块该第一加热板通过粘连件拼接成一个整体，多块该第二加热板通过卡固件可拆卸地连接至该竖直面，该第一加热板和该第二加热板均包括两层热辐射膜，两层该热辐射膜之间设有保温层，该热辐射膜相对于保温层的一侧敷设有加热带。该升温装置还具有热效高，防火阻燃，单向传热，制作方便、连接牢固、适应性强、可根据构件尺寸定尺加工等特点，能够在低温的条件下，使缓粘结预应力筋张拉不受影响，有效地避免温度对缓粘结预应力筋张拉施工的影响。
