Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The embodiment provides an aluminum film plate opposite-pulling device, as shown in fig. 2, which includes an embedded part 10 and pull tab parts 20 disposed at two ends of the embedded part 10, wherein the pull tab parts 20 are detachably connected with the embedded part 10 by threads; the embedded part 10 is a solid cylinder structure; the length of the embedded part 10 is matched with the thickness of the wall body, and the embedded part is fixedly arranged between the aluminum formworks at the two sides of the wall body; and the end of the embedded part 10 is provided with a blind hole groove of internal thread matched with the pulling piece part 20.

Further, the degree of depth in blind hole groove is not less than 100mm and be not more than 1/2 of its length, and when the degree of depth in blind hole groove was less than 100mm, pull tab portion 20 was too shallow with pre-buried portion 10 complex degree of depth, and cooperation intensity is not enough for operating personnel can't promote or operate pre-buried portion 10 through pull tab portion 20 and construct. When the depth of the blind hole groove is larger than 1/2 of the length of the blind hole groove, the matching depth of the pull tab part 20 and the embedded part 10 is too deep, so that the time for detaching the pull tab part 20 and the embedded part 10 is too long, and the overall strength of the embedded part 10 is reduced.

Further, the outer wall surface generatrix of the embedded part 10 is a straight line, that is, the embedded part 10 is a straight-wall cylinder, the embedded part 10 in the shape can be a circular cylinder structure, and the cross-sectional structure is shown in fig. 3; or a polygonal column structure, the cross section structure of which is a regular quadrangle, a regular pentagon or a regular hexagon, as shown in fig. 4-6 respectively; of course, other regular polygon structures are possible; other column solid structures with straight wall structures can also be adopted.

Furthermore, the generatrix of the outer wall surface of the embedded part 10 is a curve, that is, the outer wall surface of the embedded part 10 is a non-straight wall structure. One of the external structures is a truncated cone structure arranged for alignment connection as shown in fig. 7, and the end parts of the truncated cone structure are small-diameter surfaces, and the middle connection part is a large-diameter surface. Of course, the outer wall surface of the wavy line structure can be adopted, and the drawings are omitted.

Further, no matter what kind of structure of the outer wall surface of the embedded part 10, the blind hole groove is always arranged at the circle center position of the inscribed circle at the end part of the blind hole groove, and the embedded part 10 is integrally made of an iron material.

Further, the tab portion 20 includes a tab segment 21, and a pin 22 disposed perpendicular to the tab segment 21; the end part of the pulling segment 21 close to the embedded part 10 is provided with a screw rod which can be arranged in a blind hole groove, and one end of the pulling segment far away from the embedded part 10 is a pulling plate with a flat structure. And a gasket 23 is arranged at the connecting position of the pulling plate and the screw rod.

And a first through hole 25 matched with the pin 22 is formed in one end, far away from the screw, of the pulling plate.

Further, the pin 22 is arranged through the first through hole 25; one end of the pin 22, which is far away from the first through hole 25, is provided with a wing plate 24 which penetrates through the diameter of the pin; the wing plates 24 are symmetrically arranged relative to the axis of the pin 22, and one end of each wing plate 24 is provided with a second through hole 26.
