[0031] Embodiment 1

[0032] See also Figure 1-5 The present embodiment provides a prefabricated component forming mold, including a bottom mold 1, two side molds 2 and an end mold 3 that enclose an open mold cavity 7, and also includes a first molding mold 4, and one or more first molding molds 4 are detachably installed on the upper ends of the two side molds 2; wherein the first molding mold 4 is provided with one or more limiting holes 41 for embedded parts to pass through so as to be at least partially located in the open mold cavity 7 and to limit the embedded parts.

[0033] Specifically, at least one first molding mold 4 is detachably connected to the upper end of the two side molds 2, and the first molding mold 4 has a limiting hole 41 for the embedded part to pass through so as to be at least partially located in the open mold cavity 7 and to limit the embedded part, so that when forming the prefabricated component, at least one embedded part for docking can be embedded in the longitudinal direction of the prefabricated component, so that when the prefabricated component is docked, it can be directly connected to other prefabricated components through the embedded parts, without the need to connect the central component unit through the end face embedded structure to change the connection direction for indirect connection, so that docking is simpler and the connection operation is simpler.

[0034] In detail, when forming a prefabricated component, the position of the first molding die 4 on the upper end of the side mold 2 is set according to the predetermined position of the embedded part in the longitudinal direction of the prefabricated component. A plurality of first molding dies 4 can be arranged at intervals on the upper end of the side mold 2, which is not specifically limited here and is arranged according to production requirements. The first molding die 4 can be fixed to the upper end of the side mold 2 by bolts, or can be directly placed on the upper end of the side mold 2 and then pressed on the upper end of the side mold 2 by other structures (such as a pressure clamp, a pressure plate, etc.), which is not specifically limited here, as long as the first molding die 4 can be detachably connected to the side mold 2. In the longitudinal direction, the gaps between adjacent first molding dies 4 and between the first molding die 4 and the end mold 3 form a material distribution opening to ensure that the concrete material can enter the open mold cavity 7. One end of at least one embedded part passes through the limiting hole 41 and is located in the open mold cavity 7, and the other end is located at the upper end of the first molding die 4. The part of the embedded part located at the upper end of the first molding die 4 is used to dock with other prefabricated components. When the prefabricated components are docked, the embedded parts are overlapped together and fixed by bolts, or welded. The embedded part is preferably connected to the rigid frame in the molding die to achieve force transmission, so that the connection between adjacent prefabricated components is more stable. When molding the prefabricated components, one end of the embedded part can be first set in the open mold cavity 7, and then the first molding die 4 is mounted on the embedded part and installed on the upper end of the side mold 2; of course, the first molding die 4 can also be installed on the upper end of the side mold 2 first, and then one end of the embedded part is inserted into the open mold cavity 7 through the limiting hole 41, without specific limitation.

[0035] For further information, see Figure 2 , Figure 4 The limiting hole 41 includes a bending hole 411 through which one end of the embedded part can pass to extend into the open mold cavity 7, see Figure 5 The longitudinal cross section of the bending hole 411 is at least partially Z-shaped, L-shaped, ∪-shaped, V-shaped or wavy, that is, the bending hole 411 can be penetrated by an embedded part that is at least partially Z-shaped, L-shaped, ∪-shaped, V-shaped or wavy, that is, the embedded part can have a bearing part and a positioning part, the bearing part can be used to bear the embedded part of another prefabricated component, the positioning part can limit the position of the embedded part of another prefabricated component, and the two prefabricated components can be directly overlapped, reducing the difficulty of the connection operation. Among them, not only Figure 5 The Z-shape, L-shape, U-shape, V-shape and wave-shape shown may also be an inverted Z-shape, an inverted L-shape, an inverted ∪-shape, an inverted V-shape or an inverted wave-shape, and does not specifically refer to exactly the same Z-shape, L-shape, ∪-shape, V-shape or wave-shape, as long as the general shape is similar.

[0036] For further information, see Figure 4The limiting hole 41 includes a first through hole 412 through which one end of the positioning member can pass to connect with the embedded member. In order to further enhance the connection strength between adjacent prefabricated components, a first through hole 412 is arranged around the bending hole 411, that is, the embedded member includes a rigid bearing member arranged at the bending hole 411 and an embedded nut located around the rigid bearing member. The positioning member can be a bolt, and the bolt passes through the first through hole 412 and is screwed into the embedded nut so that the embedded nut is fixed to the first molding die 4. The positioning member can also include a bolt and a positioning nut. The outer diameter of the positioning nut is larger than the aperture of the first through hole 412. The bolt is screwed to the positioning nut and clamped on the first molding die 4, so that the positioning nut and the embedded nut can be screwed directly from the upper end to achieve the fixing of the embedded nut on the first molding die 4. The positioning nut can be removed before the prefabricated component is transported to the construction site for assembly after the prefabricated component is formed, so as to protect the embedded nut and reduce the process of plugging a sealing cover in the embedded nut after the prefabricated component is formed. When the prefabricated components are butted, the embedded nut is connected to the embedded nut of another prefabricated component through the connecting mechanical connector. Preferably, the embedded nut is connected to the rigid frame in the forming mold through the embedded rib to achieve force transmission, so that the connection between adjacent prefabricated components is more stable.

[0037] For further information, see Figure 4 The first molding die 4 has two or more first through holes 412 spaced apart, and the diameter of at least some of the first through holes 412 is different from the diameter of other first through holes 412. In order to make prefabricated components of different sizes or to be suitable for different construction conditions, it is necessary to embed pre-embed nuts of different sizes. Therefore, the different diameters of the first through holes 412 can improve the versatility of the first molding die 4. Alternatively, see Figure 2 A backing plate 6 is provided on the side of the first molding mold 4 facing away from the open mold cavity 7. The backing plate 6 has a second through hole connected to the first through hole 412 and having a different diameter. Preferably, the diameter of the first through hole 412 is larger than the diameter of the second through hole, that is, the first through hole 412 can be used for embedded nuts with a maximum aperture, and the backing plate 6 can be provided to be used for embedded nuts with a smaller aperture.

[0038] For further information, see Figure 2 , Figure 4 The first molding die 4 forms a depression toward the direction approaching the open mold cavity 7 or the first molding die 4 forms a protrusion toward the direction away from the open mold cavity 7, and the bending hole 411 is arranged at the depression or protrusion. The setting of the depression or protrusion can increase the surface area of ​​the butt joint end of the prefabricated component. Usually, after the butt joint is completed, it is necessary to cast concrete at the butt joint of the embedded parts, so that the depression or protrusion of the prefabricated component increases the contact area between the prefabricated component and the cast-in-place concrete, thereby enhancing the bonding effect.

[0039] Furthermore, a reinforcement piece is provided on the side of the first molding die 4 facing away from the open mold cavity 7 to improve the strength of the first molding die 4 .

[0040] For further information, see Figure 3 The end mold 3 is provided with a positioning hole 31, in which an inclinometer tube is inserted, and the inclinometer tube is at least partially located in the open mold cavity 7. During the production process of the prefabricated component, the inclinometer tube is fixed to the positioning hole 31 of the end mold 3, so that the inclinometer tube is pre-buried in the prefabricated component. The end mold 3 is a rigid mold. By opening a positioning hole 31 on the end mold 3 to position and fix the inclinometer tube, the smoothness of the inclinometer tube pre-buried in the prefabricated component can be greatly improved, which is beneficial to improving the monitoring data accuracy of the inclination of the prefabricated component. Preferably, the end of the inclinometer tube extends out of the positioning hole 31 and extends a predetermined length in a direction away from the open mold cavity 7, and the end of the inclinometer tube is fixed by an external component, or the end of the inclinometer tube does not exceed the positioning hole 31, and the inclinometer tube is connected to the end mold 3 by gluing or binding.

The embedded nut is fixed on the second molding die 5 through the positioning member, so that when the prefabricated component is formed, the embedded nut can be embedded at the end of the prefabricated component, which is convenient for the later connection with the connecting beam or the bottom plate through the mechanical connecting member, wherein the positioning member can be a bolt, or it can include a bolt and a positioning nut, which is the same as the positioning member of the first embodiment and will not be repeated here.
