At present, the mold structure for preparing prefabricated U-shaped concrete members is complex, and the mold disassembly and assembly process is cumbersome, resulting in low efficiency of preparing prefabricated U-shaped concrete members. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the present application provides a prefabricated U-shaped concrete member mold, aiming at improving the technical problems of complex mold structure and cumbersome mold disassembly and assembly process for preparing prefabricated U-shaped concrete members.

[0004] The present application provides a prefabricated U-shaped concrete member mold, which has a mold closing state and a mold disassembly state, and comprises:

[0005] The first mold plate piece comprises an inner mold piece and two extension ear plates, the cross section of the inner mold piece is U-shaped and extends along a first direction, the inner mold piece comprises a first plate and two second plates, the two second plates are respectively fixedly connected to the second direction sides of the first plate, and the second direction is perpendicular to the first direction; the two extension ear plates are respectively fixedly connected to the second direction sides of the second plate away from the first plate, the extension ear plate is provided with a first insertion slot extending along the first direction, and the first end of the first insertion slot is in an open structure;

[0006] The second mold plate piece has a U-shaped cross section, and comprises a third plate and two fourth plates extending along the first direction, the two fourth plates are respectively fixedly connected to the second direction sides of the third plate, each fourth plate is provided with a second insertion slot extending along the first direction, and the first end of the second insertion slot is in an open structure; when the prefabricated U-shaped concrete member mold is in the mold closing state, the first mold plate piece and the second mold plate piece are in the same plane at least one end of the first direction, the inner mold piece is located on the inner side of the second mold plate piece, each fourth plate is arranged in one first insertion slot, each extension ear plate is arranged in one second insertion slot, and the second end of the first insertion slot and the second end of the second insertion slot are in abutment; and

[0007] Two limiting units are respectively connected with the two fourth plates, each limiting unit comprises a first limiting part and a second limiting part, the first limiting part and the second limiting part are used for abutting with both sides of the extension lug plate along a third direction respectively, so as to limit the extension lug plate in the third direction, and the third direction is perpendicular to the first direction and the second direction.

[0008] Preferably, a reinforcing rib is arranged at the connection between the extension lug plate and the second plate.

[0009] Preferably, the prefabricated U-shaped concrete component mold further comprises a mold opening part, the mold opening part is arranged on the first plate and / or the third plate, and the mold opening part is used for being connected with an external force applying device.

[0010] Preferably, the mold opening part is a through hole arranged on the first plate, and the mold opening part is located on the side of the second end of the insertion slot along the first direction.

[0011] Compared with the prior art, the prefabricated U-shaped concrete component mold provided by the application at least has the following beneficial effects:

[0012] The precast U-shaped concrete component mold provided in this application, in the mold-closed state, has at least one end of the first template member and the second template member on the same plane in the first direction, with the inner mold member located inside the second template member. Each fourth plate passes through a first slot, and each extension ear plate passes through a second slot. The second ends of the first and second slots abut against each other, thus forming a U-shaped cavity between the first and second template members. At this time, the slot wall of the first slot limits the fourth plate in the second direction, and the slot wall of the second slot limits the extension ear plate in the second direction. The first and second template members are fixed in position in the second direction and cannot move relative to each other. At the same time, the slot wall at the second end of the first slot restricts the movement of the fourth plate in the first direction, and the slot wall at the second end of the second slot restricts the movement of the extension ear plate in the second direction. The movement is in the first direction; and each limiting unit is connected to a corresponding fourth plate, and each limiting unit includes a first limiting part and a second limiting part. When the precast U-shaped concrete component mold is in the closed state, the first limiting part and the second limiting part abut against the two extended ear plates on both sides along the third direction, respectively, limiting the extended ear plates in the third direction, so that the first template cannot move relative to the second template in the third direction; in addition, the first limiting part and the second limiting part of each limiting unit abut against the extended ear plates on both sides along the third direction, and can limit the extended ear plates in the third direction, so that the first template and the second template are fixed in the third direction and cannot generate relative movement; thus, the mold structure after mold closing is reliable, ensuring the stability of the cavity structure, thereby ensuring that the prepared U-shaped concrete component has a high qualification rate and stable quality. Moreover, the precast U-shaped concrete component mold structure provided in this embodiment is simple. Compared with the prior art, it does not require setting multiple template parts for splicing, installation and fixing. The mold closing process and demolding process are simple, improving the preparation efficiency of U-shaped concrete components.

[0013] Of course, any product implementing this application need not specifically need to achieve all of the technical effects described above at the same time.
