Temporary supporting device and support replacing method
The invention discloses a temporary supporting device and a support replacement method, and the method comprises the following steps that the temporary supporting device is installed at a position close to the side surface of a support, and the temporary supporting device is adjusted in place; a load is gradually applied to the temporary support device until the support is unloaded; the support tobe replaced is taken out, and a new support is installed; the temporary supporting device is unloaded and adjusted, so that the support bears the load; the temporary supporting device is dismounted,and installation is completed. The temporary supporting device comprises a height adjusting system and a power driving device, the height adjusting system comprises an upper plate, a lower plate and an adjusting block, an open groove is formed in the bottom face of the upper plate and is of a V-shaped structure, an adjusting cavity is formed between the open groove and the lower plate, and the adjusting block is located in the adjusting cavity and can slide in the adjusting cavity to enable the upper plate to rise or fall. Jacking of the support with large vertical bearing capacity can be achieved through small horizontal or lateral loads, the jacking force and/or stroke can be accurately controlled, the relative jacking difference of all supporting points can be accurately controlled to be within an allowable range, and damage to the structure is reduced to the maximum extent.
本发明公开了一种临时支撑装置及支座更换方法，包括以下步骤：在临近支座侧面位置安装临时支撑装置，调节就位；对临时支撑装置逐步施加荷载，至支座卸载；取出待更换支座，安装新支座；对临时支撑装置进行卸载调节，使支座承受荷载；拆除临时支撑装置，安装完成。临时支撑装置包括调高系统和动力驱动装置，调高系统包括上板、下板和调节块，所述上板底面设有开口槽，开口槽呈类V形结构，开口槽与下板之间形成调节腔，调节块位于调节腔内且能在调节腔内滑动并使得上板高度上升或下降。本发明可采用很小的水平或侧向荷载实现较大竖向承载力支座的顶升，且能准确控制顶升力和/或行程，并能准确控制各支点相对顶升高差在容许范围内，最大限度降低对结构的损伤。
