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 6, the retractable formwork device for cast-in-place concrete preformed hole provided by the present invention comprises a formwork system and a fixing bracket 8; the template system comprises a bottom plate 5, a rotating shaft 3, a supporting rod 1 and supporting arc plates 2, wherein the bottom plate 5 is fixedly connected with the rotating shaft 3, the rotating shaft 3 is movably connected with the supporting rod 1, the supporting rod 1 is movably connected with the supporting arc plates 2, and the supporting arc plates 2 are connected by adopting a diagonal plane lap joint structure; the rotating pin 6 vertically penetrates through the upper part of the rotating shaft 3, the rotating shaft 3 vertically penetrates through the fixed support 8, and a groove 9 for clamping the rotating pin 6 is formed in the fixed support 8.
The rotating shaft 3 and the supporting arc plate 2 are respectively connected with two ends of the supporting rod 1 through a first pin shaft 4.
The rotation pin 6 is connected to the rotation shaft 3 through a second pin shaft 7.
The fixing support 8 is provided with a through hole 10, and the through hole 10 is positioned in the groove 9. The upper end of the rotating shaft 3 penetrates through the through hole 10, the rotating pin 6 at the upper end of the rotating shaft 3 is installed, and the rotating pin 6 is placed in the groove 9 to lock and fix the template system.
The number of the supporting arc plates 2 is more than 2, and the optimal number is 8; the supporting rods 1 are divided into an upper group and a lower group, the number of the supporting rods is 2 times that of the supporting arc plates 2, and the number of the supporting rods is preferably 16.
Referring to fig. 3, the connecting surfaces of the supporting arc plates and the supporting arc plates are inclined planes, and the inclined planes of the two supporting arc plates are complementarily lapped together, so that the phenomenon that concrete flows into the reserved hole due to the fact that a right-angle splicing seam is easy to open is avoided; when the supporting arc plates are stressed unevenly and gaps appear, the inclined plane lapping structure between the supporting arc plates effectively prevents concrete from flowing into the preformed hole template.
Referring to fig. 2, the rotating pin 6 is rotated to drive the rotating shaft 3 to open the supporting arc plate 2, and the rotating pin 6 is placed in the groove 9 to lock the template system. And placing the unfolded template device at the specified position of the prepared hole, and leveling the plane position of the prepared hole by using the fixed support 8 to perform concrete operation. After the concrete operation is completed, the rotating pin 6 is taken out of the groove 9, the rotating shaft 3 is reversed, the supporting arc plate 2 is contracted, the diameter of the template system is reduced to be smaller than the diameter of the preformed hole, the template device is pulled out from the preformed hole, and the template device is rapidly dismantled.
Finally, it is noted that: the preferred embodiments of the present invention have been shown and described, and it will be understood that modifications and variations may be made by those skilled in the art without departing from the scope of the invention.
