Detailed Description

The invention will be further explained in detail with reference to the drawings and the following detailed description:

example (b):

referring to fig. 1, a concrete placement template is to drawing mechanism, including the pull rod 3 that passes inner formword 1 and outer formword 2, be located the first closure plate 4 that is used for preventing the concrete leakage of inner formword 1 keeping away from outer formword 2 one side, be located the second closure plate 5 that is used for preventing the concrete leakage of outer formword 2 keeping away from inner formword 1 one side, be located between inner formword 1 and the outer formword 2 and be used for carrying out spacing sleeve pipe 6 to inner formword 1 and outer formword 2, threaded connection is at the nut 7 of pull rod 3 one end, be located pull rod 3 keep away from nut 7 one end be used for with the nut 7 cooperation thereby prevent inner formword 1 and outer formword 2 interval grow. Be equipped with on the inner formword 1 with the first recess 14 of first shutoff board 4 adaptation, first shutoff board 4 is located first recess 14, be equipped with on the exterior sheathing 2 with the second recess 15 of 5 adaptations of second shutoff board, second shutoff board 5 is located second recess 15. The first plugging plate 4 is square and the second plugging plate 5 is square. The anti-rotation section 9 is square in cross section.

The pull rod 3 comprises a threaded section 8 in threaded fit with the nut 7, an anti-rotation section 9 penetrating through the first plugging plate 4 and a counter-pull section 10 with a smooth surface; the pull rod 3 is an integrally formed structure.

The opposite-pulling section 10 penetrates through the inner template 1, the sleeve 6, the outer template 2 and the second plugging plate 5.

The projection of the cross section of the anti-rotation section 9 towards the counter-pulling section 10 is positioned in the cross section of the counter-pulling section 10, and the projection of the cross section of the thread section 8 towards the anti-rotation section 9 is positioned in the cross section of the anti-rotation section 9.
