DETAILED DESCRIPTION

[0054] 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.

[0055] Please refer to Figure 1-30 According to an embodiment of the utility model, a combined structure of a prefabricated component mold is provided, including a side mold 1 of the prefabricated component mold, and a side end cavity mold 3 for constructing a side end cavity 2 at the side end of the prefabricated component, and a horizontal stirrup 4 is sleeved on the outer side of the side end cavity mold 3; when the mold is removed, the side end cavity mold 3 can be longitudinally pulled out from the horizontal stirrup 4. The combined structure also includes a concave-convex structure that is connected to the end of the horizontal stirrup 4 and is provided with convex areas 5 and concave areas 6 alternately distributed, and the edge of the horizontal stirrup 4 is placed in the concave area 6 of the concave-convex structure. In this way, the edge of the horizontal stirrup 4 can be hidden in the concave-convex structure, and when concrete is poured into the prefabricated component mold, the convex area 5 forms a barrier to the concrete, so that after the concrete is formed and the mold is removed, the edge of the horizontal stirrup 4 will be exposed at the side end of the cavity.

[0056] According to the different configurations of prefabricated component molds, they are introduced below.

[0057] In one embodiment, Figure 3-7 , the prefabricated component mold is a linear component mold, accordingly, Figure 8-9 If the manufactured component is a straight wall, the concave-convex structure is arranged on the inner side of the side mold 1.

[0058] In another embodiment, the combined structure also includes a mold box 7 for setting a prefabricated component mold. If the prefabricated component mold is an L-angle component mold, the side end of the mold box 7 is constructed with a corner area 8 that is adapted to the corner portion of the L-angle component mold. A concave-convex structure is arranged on the surface of the corner area 8 for the horizontal stirrups 4 of the side end cavity mold 3 of the L-angle component mold at the corner to be placed.

[0059] The L-angle component mold includes a straight portion 9 and a corner portion 10, and the side end cavity mold 3 includes a first side end cavity mold 11 arranged at the side end of the straight portion 9, and a second side end cavity mold 12 arranged at the corner portion 10, which are respectively used to make a first side end cavity 27 and a second side end cavity 28. A gap is left between the first side end cavity mold 11 and the second side end cavity mold 12, and the horizontal stirrup 4 is sleeved on the outside of the first side end cavity mold 11 and the second side end cavity mold 12.

[0060] In another embodiment, if the horizontal stirrups 4 of the prefabricated component are exposed in the middle of the prefabricated component, that is, used for a T-shaped wall, a middle cavity mold 13 is set in the middle of the prefabricated component mold, and the horizontal stirrups 4 are also sleeved on the outside of the middle cavity mold 13; the concave-convex structure is set on the surface of the middle cavity mold 13.

[0061] As an example, the concave-convex structure can be a plurality of plate-like structures welded on the side mold 1, the mold box 7, and the middle cavity mold 13, with gaps left between adjacent plate-like structures so that the plate-like structures constitute the raised area 5 of the concave-convex structure, and the adjacent gaps constitute the recessed area 6, in which the horizontal stirrups 4 are placed.

[0062] The prefabricated component mold further includes a bottom mold 14 and a core mold 15; bosses 16 are arranged at intervals on the bottom mold 14 to form a flange 26 at the bottom of the prefabricated component; the bosses 16 are arranged with a first cavity 17 for fixing the bottom of the core mold 15, so that the fixing of the core mold 15 is more stable. The bottom of the first cavity 17 is connected to the second cavity 18, which is used for a mechanical support component that lifts the core mold 15 when the mold is removed, such as a push rod of an oil cylinder, or for a connecting component or a force-bearing component at the bottom of the core mold 15 to pass through. The connecting component and the force-bearing component are used to cooperate with the mechanical support component that lifts the core mold 15 when the mold is removed. For example, the force-bearing component can be a columnar protrusion protruding from the bottom of the core mold 15.

[0063] As an example, the side end cavity mold 3 is wide on the outside and narrow on the inside to form a wedge-shaped structure to enhance the bonding strength between new and old concrete.

[0064] The steel bars in the prefabricated component mold are prefabricated steel bars or post-inserted steel bars. For example, the vertical steel bars 19 can be prefabricated steel bars or post-inserted steel bars that are inserted into the vertical cast-in-place cavity 20 later.

[0065] The prefabricated component mold is a prefabricated component mold without insulation or a prefabricated component mold with insulation. If it is a prefabricated component mold with insulation, the prefabricated component mold also includes an insulation layer 21 and a steel mesh 23 arranged on the outside of the insulation layer 21 for combining with the outer page 22.

[0066] In another embodiment, the combined structure further comprises a mold box 7, the surface of which is provided with protrusions 24 to construct grooves 25 on the surface of the prefabricated component. This structure is particularly suitable for constructing a prefabricated component with a large area of ​​grooves 25 on the surface.

[0067] Combination Fig.31 There is an anti-ridge 29 structure at the bottom of the core mold 15, and its cross-sectional area is smaller than the cross-sectional area of ​​the upper part of the core mold 15, so that in the prefabricated component produced, an anti-ridge 30 is formed at the bottom of the vertical cast-in-place cavity 20, so that the new and old concretes are better combined, the strength is higher, and the concrete slippage and the like are prevented.

[0068] 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.
