Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] Such as Figure 1 to Figure 8 As shown, the dismounting method of the bridge high pier turning formwork described in the present invention adopts telescopic device to dismantle template 10, and described telescopic device comprises sliding box 1, telescopic rod 2; One end surface penetrates to the other end surface; the telescopic rod 2 is slidingly matched with the sliding box 1;
[0030] The two opposite sides on the sliding box 1 are all provided with track limiting devices; The direction perpendicular to the axis of the telescopic rod 2 is distributed; the limit wheel set 4 includes a track inner runner 41 and a track outer runner 42; the outer circumference of the track inner runner 41 and the outer circumference of the track outer runner 42 There is a track installation gap between the surfaces;
[0031] Also includes the following steps...

The invention discloses a bridge high pier rollover template disassembly method which is easy and simple to operate, and capable of improving the template disassembly efficiency. The disassembly method adopts a telescopic device for disassembly. The telescopic device comprises a sliding box and a telescopic rod. The telescopic rod penetrates into the other end face of the sliding box from one end face; the telescopic rod and the sliding box are matched in a sliding way. The disassembly method also comprises the steps of 1, installing the telescopic device; 2, extending one end of the telescopic rod of the telescopic device out to be fixedly connected with a template; 3, disassembling a fastener used for hooping the template on concrete; 4, controlling the telescopic device to make the end, connected with the template, of the telescopic rod move towards the direction of a vertical guide beam, so that the template is separated from the concrete and an interval is formed between the template and the concrete; and 5, controlling the telescopic device to slide upwards or downwards along the vertical guide beam; completing the disassembly of the template. By adopting the disassembly method of the template, the labor intensity can be reduced, and the construction cost is lowered.
Description
technical field [0001] The invention relates to the field of dismantling the overturned formwork for bridge pier columns, in particular to a method for disassembling the overturned formwork for high bridge piers. Background technique [0002] It is known that during the construction of the traditional formwork formwork for bridge pier columns today, hydraulic pressure, hoists and other telescopic devices are used to lift the formwork into place vertically. The sliding track and the load-bearing components under the track are set to complete the horizontal disassembly and placement of the formwork. These today's general bridge pier column formwork removal methods are not safe, troublesome to operate, high in labor intensity and low in construction efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for dismantling the overturned formwork for high pier bridges, which is easy to operate and can imp...
