Detailed Description

The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments shown in the drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand the invention and to implement the invention, and are not intended to limit the scope of the invention in any way.

Referring to fig. 1-2, an embodiment of the present invention provides a core mold for a prefabricated part, including a core mold main body 1, wherein one end of the core mold main body 1 is connected to a side mold 2 and extends a distance relative to the side mold 2.

The core body 1 has a substantially box shape with a cavity therein, and the cavity portion includes a space 3 for receiving a longitudinal reinforcing bar. In this embodiment, the core mold body 1 has portions protruding to both front and rear sides to form the tendon grooves 4 for receiving the longitudinal tendons. The reinforcing bar groove 4 can be formed in several numbers (e.g. 2 in fig. 1 and 3 in fig. 3) on the core mold body 1.

In this embodiment, the longitudinal reinforcing bars 15 include two longitudinal reinforcing bars arranged along the front and rear sides of the core mold body 1, the bottoms of the two longitudinal reinforcing bars are connected together by the closed reinforcing bar 5, and the closed reinforcing bar 5 is substantially arc-shaped, so that the bonding area between the longitudinal reinforcing bar and the concrete is increased, and the anchoring strength of the upper and lower prefabricated members when connected is improved.

An openable baffle 6 is arranged on one side of the core mould main body 1 far away from the side mould 2, and the openable baffle 6 is connected with the core mould main body 1 through a rotating shaft 7, so that the space 3 for accommodating longitudinal steel bars is opened and closed. Certain gaps are left between the front side and the rear side of the openable baffle 6 and the inner edge of the core mould main body 1 to form a hole 8 for the longitudinal steel bar to pass through. When concrete is poured into the mold, the openable and closable shutter 6 is in a closed state to block the entry of concrete, so that a cavity corresponding to the shape of the core mold body 1 is formed in the precast member. When the prefabricated member is completed, the core mold is withdrawn from the prefabricated member, and the closing rib 5 at the bottom is brought into contact with the openable and closable stopper 6 to push it open, so that the core mold main body 1 and the longitudinal reinforcing bars 15 are separated.

The side of the space 3 for accommodating the longitudinal steel bars of the prefabricated part is provided with a first steel bar positioning baffle plate 9 in the horizontal direction, and one end of the space 3 for accommodating the longitudinal steel bars of the prefabricated part, which is close to the side formwork 2, is provided with a second steel bar positioning baffle plate 10 in the vertical direction. In this embodiment, the two ends of the first rebar positioning baffle 9 are fixed on the inner wall of the rebar groove 4. The second steel bar positioning baffle 10 is vertically fixed with the first steel bar positioning steel plate. The first reinforcing bar positioning baffle 9 may be disposed on both sides of the longitudinal reinforcing bar 15, or may be disposed only on one side of the longitudinal reinforcing bar 15, and the other side forms a barrier by the inner wall of the core mold main body 1. The longitudinal steel bars 15 are blocked and positioned by the first steel bar positioning baffle 9 in the horizontal direction and by the second steel bar positioning baffle 10 in the vertical direction, so that the horizontal and vertical directions cannot deviate, and the position of the longitudinal steel bars 15 is accurate after the prefabricated part is manufactured.

As described above, one end of the core mold body 1 protrudes with respect to the side mold 2. In this embodiment, a core mold fixing member is fixed to the side wall of the extension portion, and the core mold fixing member is detachably connected to the side mold 2. According to the embodiment of the present invention, the core mold fixing member is an angle member 11 having two mutually perpendicular surfaces, one surface of the angle member 11 is fixedly connected to the side surface of the core mold main body 1, and the other surface is connected to the side mold 2, and the connection means may be a screw 12, a bolt, or the like. After the core mould is fixed, the core mould is not easy to move in the manufacturing process of the prefabricated part, and the precision of the position of the cavity in the prefabricated part is also improved.

The number of the angle members 11 is two, and the angle members 11 are provided on both sides of the core mold body 1, respectively, and if the angle members 11 are provided diagonally, a more uniform fixing force can be exerted.

One end of the core mould main body 1 close to the side mould 2 is provided with a connecting structure for dragging the core mould. In this embodiment, the connecting structure includes two parallel connecting plates 13 and a cross bar 14 connecting the two connecting plates 13 together.
