Detailed ways

The specific embodiment of the present utility model refers to Fig. 1-13:

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The specific casting method and process of the cylinder are well-known technologies and will not be described here.

The technical scheme of the present utility model is:

A new type of cylindrical formwork, as shown in Figure 1-7, includes 4 formwork assemblies 1 that can be bent and deformed. Formwork assembly 1 is made of white iron sheet. There is a folded edge 1-1 that is folded outward, and two adjacent folded edges 1-1 are stacked together. The supporting plate 2 is connected with five assembly bolts 3 passing through the folded edges 1-1 to ensure that the folded edges 1-1 are tightly stitched together. The top of the supporting plate 2 is provided with a sunken slot 2-1. The bottom is provided with a plug-in board 2-2 that protrudes downward and matches the slot 2-1. The depth of the socket 2-1 is greater than the length of the plug-in board 2-2, and the upper part of the support board 2 is provided with a pass-through slot. The docking hole A 4 of 2-1, the middle part of the plug-in board 2-2 is provided with a docking hole B 5 which runs through both ends, the centers of the docking hole A 4 and the docking hole B 5 are both located on the center line of the support plate 2, and the docking hole The distance from A4 to the upper edge of the support plate 2 is equal to the distance from the docking hole B5 to the upper edge of the insert plate 2-2, to ensure that the template can be installed smoothly when it is used on site. A rubber pad is set between -1 to increase the sealing performance when the folded edges 1-1 are stacked.

When the cylindrical formwork is assembled on site, as shown in Figure 8-10, the support mechanism is first put in place. The support mechanism includes a base 7, a rotating shaft 8, a sleeve 9, a telescopic rod 10 and an arc-shaped support plate 11.
