Under this state, form the joint effect between fixture block 97 and the draw-in groove 98, first semicircle frame 1 and the unable separation of second semicircle frame 2 to guaranteed that two 3 tip of semicircle boards are in the same place. When first semicircle frame 1 and second semicircle frame 2 need be separated, only need to rotate round bar 96 and drive fixture block 97 and rotate half a circle for fixture block 97's arcwall face upset, then first semicircle frame 1 of reverse pulling and second semicircle frame 2, insert block 92 from slot 91 when leaving laminating fixture block 97's arcwall face and with fixture block 97 promotion entering holding tank 93 in, until fixture block 97 leaves from draw-in groove 98. The first semicircular frame 1 and the second semicircular frame 2 are continuously pulled reversely, and the fixture block 97 is attached to the side wall of the insertion block 92 and slides relative to the side wall of the insertion block 92 until the insertion block 92 leaves the slot 91.
The end of the round rod 96 outside the slot 91 is fixedly provided with a limiting wheel 99, and the end surface of the limiting wheel 99 is provided with a square groove 910. The outer side walls of the first semicircular frame 1 and the second semicircular frame 2 are horizontally matched with a limiting frame 911 matched with the square groove 910 in a sliding manner. In the concrete pouring process, the limiting wheel 99 is limited through the matching of the limiting frame 911 and the square groove 910, so that the limiting wheel 99 and the round rod 96 are prevented from freely rotating, the insertion block 92 is prevented from being separated from the slot 91, and the end faces of the first semicircular frame 1 and the second semicircular frame 2 are attached together.
An Contraband-shaped positioning frame 10 is horizontally and slidably matched on the guide sleeve 6. The surfaces of the first semicircular frame 1 and the second semicircular frame 2 are horizontally provided with positioning holes 11 matched with the positioning frame 10. Under the state that locating rack 10 inserted locating hole 11, the terminal surface of two semicircle boards 3 is respectively with first semicircle frame 1 and the 2 terminal surfaces parallel and level of second semicircle frame. Realized the location of semicircle board 3, first semicircle frame 1 and 2 relative position of second semicircle frame through locating rack 10 and locating hole 11 to when having guaranteed to separate first semicircle frame 1 and second semicircle frame 2, 3 terminal surfaces of semicircle board respectively with first semicircle frame 1 and 2 parallel and level of second semicircle frame, avoid semicircle board 3 to cause the interference to the separation of first semicircle frame 1 and second semicircle frame 2.
As shown in fig. 1, the embodiment further provides a high-strength building concrete column pouring construction method, which is completed by matching the high-strength building concrete column pouring construction device, and includes the following steps:
step one, butt joint and fixation: the end parts of the first semicircular frame 1 and the second semicircular frame 2 are butted together through the clamping mechanism 9, so that the first semicircular frame 1 and the second semicircular frame 2 are fixedly connected to form a circular frame, and the end parts of the two semicircular plates 3 are attached together to form a circular plate with the axis of the circular frame coinciding.
Step two, pouring and trowelling: and (3) smearing a release agent on the inner walls of the semicircular plates, pouring concrete on the inner sides of the two semicircular plates 3, simultaneously rotating the two semicircular plates 3 to drive the guide rod 5 and the guide sleeve 6 to synchronously rotate, and trowelling the outer circumferential surface of the concrete column through the inner walls of the semicircular plates 3.
Step three, standing for heat dissipation: the poured concrete column is placed still, and during the standing, the sealing rod 74 is driven to move in the vertical groove 73 by pressing the connecting plate 76 downwards, so that the air in the heat dissipation groove 71 is dissipated.
Step four, stripping and separating: through lifting ring 85 in the lifting mechanism 8, semicircular arc plate 3 and guide sleeve 6 are lifted, so that semicircular arc plate 3 is separated from the outer circumferential surface of the concrete column along the axial direction of the concrete column, the clamping between first semicircular frame 1 and second semicircular frame 2 is released through clamping mechanism 9, and first semicircular frame 1 and second semicircular frame 2 are separated.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
