Detailed Description

The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and functions of the present invention, but the present invention is not limited thereto.

Referring to fig. 1 to 4, the present invention provides a formwork device for post-cast plate of pipe well, which is composed of a laminated plate 1, a first batten 4, a second batten 3, a steel pipe 5, etc. Rows of round holes 6 corresponding to the positions are reserved on concrete walls 7 on the two sides of the pipe well; the steel pipe 5 is transversely inserted between the two concrete walls 7 through the round hole 6; first flitch 4 is equipped with to 1 lower surface equipartition of tectorial membrane multiply wood, and the both sides of every first flitch 4 are fixed with second flitch 3 respectively, and first flitch 4 and second flitch 3 constitute opening groove structure down, a steel pipe 5 of buckle in every recess.

The general post-cast plate design is applied to the pipe shaft beside the elevator shaft and is used for unloading and subsequent pipe installation at the pipe shaft part. The construction method of the formwork device for the post-cast plate of the pipe well comprises the following steps:

step one, before the concrete is poured on the pipe well concrete wall 7, a row of round holes 6 are reserved on the concrete wall 7 at the lower side position of each rear pouring plate in advance, the round holes 6 are used for steel pipes 5 to pass through, and the smoothness of the round holes 6 after the concrete wall 7 is poured is guaranteed. The positions of the reserved round holes 6 on the two opposite concrete walls 7 of the pipe well are the same.

And step two, when the construction of the post-cast plate of the pipe well is started after the construction of the peripheral main body structure is finished, penetrating the steel pipes 5 into the circular holes 6 reserved in the opposite concrete wall 7 from the circular holes 6 reserved in the concrete wall 7 on one side to form a row of steel pipes 5, as shown in fig. 2.
