DETAILED DESCRIPTION

[0053] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0054] A mold for making a prefabricated column provided in an embodiment of the present invention includes a large cavity mold formed by enclosing a plurality of small cavity molds, so that the large cavity mold is used to construct a cavity structure inside the prefabricated column; the inner wall of the cavity structure is constructed into a mortise and tenon structure or a flushing rough surface through the mortise and tenon grooves on the small cavity molds. The mortise and tenon structure can increase the bonding strength between new and old concrete, making the overall strength of the prefabricated column better.

[0055] Small cavity molds include one or more of the following:

[0056] A drawing die 1 capable of direct vertical drawing; as an example, the structure may be square or may be other shapes.

[0057] The rotating mold 2 can be removed by rotating; the rotating mold 2 is provided with a bar-exposed baffle plate 3, and the bar-exposed baffle plate 3 is configured with a gap 6 for the transverse reinforcement 4 and / or the longitudinal reinforcement 5 of the prefabricated column to pass through. As an example, the rotating mold 2 can be circular or semicircular.

[0058] The rotating mold 2 includes a curved surface structure, and a bar-exposed baffle plate 3 is arranged on the side of the curved surface structure; there are multiple gaps for the transverse reinforcement 4 and / or the longitudinal reinforcement 5 of the prefabricated column to pass through, and the gaps are arranged vertically at intervals along the bar-exposed baffle plate 3. In this way, the transverse reinforcement 4 and the longitudinal reinforcement 5 can pass through the gap 6 without being affected.

[0059] The surface of the cambered surface structure is also provided with a transverse protrusion structure 7 extending along the periphery of the cambered surface structure. This structure can increase the bonding area of ​​new and old concrete instead of roughening.

[0060] Furthermore, 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, it can also increase the bonding area between new and old concrete, making the strength of the prefabricated column more stable.

[0061] In this embodiment, the shear groove structure 8 is a wedge-shaped structure that gradually narrows toward the cavity structure, so that the new and old concrete can form a mutually embedded structure, thereby improving the overall strength of the prefabricated column.

[0062] Furthermore, the bottom of the rotating mold 2 has a connecting portion 9, which is connected to the elongated fixing groove 11 through a horizontally arranged connecting pin 10, so that after the connecting pin 10 is pulled out, the rotating mold 2 can also move along the elongated fixing groove 11 toward the inner side of the cavity structure during rotation.

[0063] Furthermore, a reinforcement structure is provided on the top of the small cavity mold. In this embodiment, the reinforcement structure can be a reinforcement plate 12 connected to the top of the small cavity mold and arranged in a staggered manner in the horizontal and vertical directions.

[0064] Furthermore, the exposed reinforcement baffle plate 3 is located on the side of the rotating mold 2 close to the inner wall of the precast column in the rotating mold 2. Taking the circular rotating mold 2 as an example, with the center line of the circular outer wall as the boundary, the exposed reinforcement baffle plate 3 is closer to the center line toward the precast column, so that the protruding concrete on the inner side of the precast component can be reduced.

[0065] According to one aspect of the present invention, a prefabricated column is provided, which is manufactured by the above-mentioned manufacturing mold, and includes a concrete body 13, and the inner side of the concrete body 13 is a cavity structure constructed by a large cavity mold surrounded by multiple small cavity molds. The concrete body 13 has vertical steel bars 17 inside.

[0066] Furthermore, the inner wall of the cavity structure has any one or more of the following structures:

[0067] Shear grooves 14, which are arranged vertically along the inner wall of the cavity structure;

[0068] Arc-shaped grooves; the arc-shaped grooves are arranged vertically along the inner wall of the cavity structure.

[0069] Furthermore, the arc-shaped grooves are vertically alternately arranged in a concave-convex structure on the inner wall of the cavity structure, that is, the first arc-shaped grooves 15 and the second arc-shaped grooves 16 are alternately arranged.

[0070] According to one aspect of the present invention, there is also provided a method for manufacturing a prefabricated column, which is implemented using the above-mentioned manufacturing mold, and the method comprises:

[0071] Enclosing the small molds into a large cavity mold, so that the large cavity mold is used to construct the cavity structure inside the prefabricated column;

[0072] The steel bars that are staggered horizontally and vertically pass through the exposed steel bar baffle;

[0073] Casting the outer part of the large cavity mold to form the cast-in-place concrete structure of the precast column;

[0074] After the concrete solidifies, the small molds are removed to obtain prefabricated columns.

[0075] Further,

[0076] Methods for removing small molds include:

[0077] For drawing dies that can be directly drawn vertically, they can be removed by direct vertical drawing;

[0078] For the rotating mold, control its rotation while moving toward the inside of the precast column, and take it out from the precast column when it is rotated to a position where it is not affected by the horizontal and vertical crisscrossed steel bars.

[0079] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
