Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0045] The prefabricated column manufacturing die provided in the embodiments of the present application comprises a plurality of small cavity molds enclosed to form a large cavity mold, so that the large cavity mold is used to construct the cavity structure inside the prefabricated column; and the inner wall of the cavity structure is constructed into a mortise and tenon structure or a rough surface through the mortise and tenon structure on the small cavity mold. The mortise and tenon structure can increase the bonding strength between new and old concrete, so that the overall strength of the prefabricated column is better.

[0046] The small cavity mold comprises one or more of the following:

[0047] The drawing die 1 can be directly vertically drawn; as an example, the structure can be square or other shapes.

[0048] The rotating die 2 can be removed by rotation; the rotating die 2 is provided with an exposed reinforcement baffle 3, and the exposed reinforcement baffle 3 is constructed with a gap 6 for the transverse reinforcement 4 and / or longitudinal reinforcement 5 of the prefabricated column to pass through. As an example, the rotating die 2 can be circular or semicircular.

[0049] The rotating die 2 comprises an arc surface structure, and the side part of the arc surface structure is provided with the exposed reinforcement baffle 3; the gap for the transverse reinforcement 4 and / or longitudinal reinforcement 5 of the prefabricated column to pass through is multiple and vertically spaced along the exposed reinforcement baffle 3. In this way, the transverse reinforcement 4 and the longitudinal reinforcement 5 can pass through the gap 6 without being affected.

[0050] The surface of the arc surface structure is further provided with a transverse protruding structure 7 extending along the peripheral surface of the arc surface structure. This structure can increase the bonding area of new and old concrete, instead of roughening.

[0051] Further, the drawing die 1 is also provided with a shear groove structure 8 along the vertical direction as a kind of mortise and tenon structure, which can also increase the bonding area of the new and old concrete, so that the strength of the prefabricated column is more stable.

[0052] In this embodiment, the shear groove structure 8 is a wedge-shaped structure that gradually narrows towards the cavity structure, which can make the new and old concrete form a mutually embedded structure, thereby improving the overall strength of the prefabricated column.

[0057] Further, the inner wall of the cavity structure has any one or more of the following structures:

[0058] The shear groove 14 is arranged vertically along the inner wall of the cavity structure;

[0059] The arc-shaped groove is arranged vertically along the inner wall of the cavity structure.

[0060] Further, the arc-shaped grooves are arranged vertically in a concave-convex structure on the inner wall of the cavity structure, i.e., the first arc-shaped groove 15 and the second arc-shaped groove 16 are arranged alternately.

[0061] According to one aspect of the present application, a prefabricated column manufacturing method is also provided, which is realized by using the above-mentioned manufacturing die. The method comprises:

[0062] Surrounding the small die into a large cavity die so that the large cavity die is used to construct the cavity structure inside the prefabricated column;

[0065] After the concrete is solidified, the small molds are removed to obtain the precast column.

[0066] Further,

[0067] The removal method of the small mold comprises:

[0068] For the pulling mold that can be directly vertically pulled, the pulling mold is directly vertically pulled and removed;

[0069] For the rotating mold, the rotating mold is controlled to rotate and move to the inside of the precast column at the same time, and the rotating mold is removed from the inside of the precast column after the rotating mold is rotated to a position that is not affected by the transverse and longitudinal intersecting steel bars.

[0070] The above only describes the preferred embodiments of the present application. It should be noted that, for those skilled in the art, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
