Description

Technical Field

[0001] The utility model relates to the technical field of precast part molds, in particular to a precast mold for concrete structural parts. Background Art

[0002] Concrete precast structural parts are building components prefabricated in a factory with concrete as the basic material. Molds are required during the prefabrication of concrete precast structural parts. In the existing prefabrication process of concrete components, pouring is usually carried out in a fixed mold, and the mold is removed after the concrete is formed.

[0003] There is a existing concrete precast part mold (its authorization announcement number is: CN218518867U). By adjusting the cooperation between the mold plate and the mold side plate, the adjusting screw will drive the movement of the adjusting mold plate to engage and fix the mold side plate. The concrete is poured between the mold side plates for prefabrication, so that it can be adjusted to a suitable length for prefabrication as needed. Only by carrying mold side plates of different lengths can the formation of concrete precast parts be completed.

[0004] However, this kind of concrete precast part mold has some deficiencies in the actual use process: when prefabricating concrete structural parts of different length dimensions, it is necessary to configure and replace mold side plates of different lengths, which increases the material cost of accessories and reduces the practicability of the precast part mold. Therefore, we propose a precast mold for concrete structural parts to solve the above problems. Summary of the Utility Model

The same mold side plate is movably installed between the corresponding first installation groove and the second installation groove. Positioning grooves are opened on one side wall of the two mold side plates. A positioning plate is movably installed inside the precast mold base and the mold frame. The two protruding plates on one side wall of the positioning plate are respectively inserted into the corresponding positioning grooves. A first translation adjustment mechanism for the positioning plate is arranged on one side wall of the mold frame. A translation groove is opened inside the precast mold base. A translation plate is movably installed inside the translation groove. The translation plate is fixedly connected to the two mold side plates. A second translation adjustment mechanism for the translation plate is arranged on one side wall of the precast mold base.

[0008] Preferably, the first translation adjustment mechanism includes a first rotating seat, a first threaded rod, a turntable and a guide rod. One side of the positioning plate is fixedly installed with the first rotating seat. One end of the first threaded rod is rotatably installed on one side of the first rotating seat. The other end of the first threaded rod threadedly penetrates outside the mold frame and is fixedly installed with the turntable. One ends of two guide rods are respectively fixedly installed on one side of the positioning plate, and the other ends of the two guide rods movably penetrate outside the mold frame. By screwing the turntable on the first threaded rod, under the guiding action of the two guide rods, the two protruding plates on one side wall of the positioning plate are inserted into the positioning grooves on one side of the two mold side plates, so as to form a precast chamber for concrete structural members between the precast mold base, the mold frame, the two mold side plates and the positioning plate.

[0009] Preferably, both the first installation groove and the second installation groove are arranged in a convex structure, and the translation groove is communicated with the two second installation grooves; it is convenient for the translation plate in the translation groove to move and drive the mold side plate in the second installation groove to move.

[0010] Preferably, the second translation adjustment mechanism includes a second rotating seat, a second threaded rod and a grip disc. A second rotating seat is arranged on the inner wall of one side of the translation groove. One end of the second threaded rod is rotatably installed on one side of the second rotating seat. The other end of the second threaded rod threadedly penetrates outside the translation plate and is fixedly installed with the grip disc. By screwing the grip disc on the second threaded rod, the length of the two mold side plates extending into the mold frame can be indirectly adjusted.

[0011] Preferably, a first scale is arranged on the inner wall of one side of the mold frame, and the first scale is located on the inner wall of the mold frame close to the positioning plate; it is convenient to know the height of the concrete injected into the precast chamber.

[0012] Preferably, two second scales are arranged on the top side of the mold frame, and one side of each of the two mold side plates is respectively attached to and points to the corresponding scale value on the corresponding second scale; by observing the values on the second scale pointed to by one side of the two mold side plates, the length of the two mold side plates extending into the mold frame can be known.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] For this precast mold for concrete structural members, by screwing and adjusting the grip plate on the second threaded rod, the translation plate synchronously drives the two mold side plates to move on the two side walls of the mold frame. By observing the values corresponding to the second scale on one side of the two mold side plates, the length of the two mold side plates on the two side walls of the mold frame can be adjusted, forming precast cavities for concrete structural members of different lengths, thus realizing the precasting of concrete structural members of different length dimensions.

A second translation adjustment mechanism for the translation plate 13 is provided on one side wall of the precast mold base 1.

[0022] Further, the first translation adjustment mechanism includes a first rotating seat 8, a first threaded rod 9, a turntable 10, and a guide rod 11. One side of the positioning plate 7 is fixedly installed with a first rotating seat 8. One end of a first threaded rod 9 is rotatably installed on one side of the first rotating seat 8. The other end of the first threaded rod 9 threadedly penetrates outside the mold frame 2 and is fixedly installed with a turntable 10. One ends of two guide rods 11 are respectively fixedly installed on one side of the positioning plate 7. The other ends of the two guide rods 11 movably penetrate outside the mold frame 2. By screwing the turntable 10 on the first threaded rod 9, under the guiding action of the two guide rods 11, the two protruding plates on one side wall of the positioning plate 7 are driven to be inserted into the positioning grooves 6 on one side of the two mold side plates 5, so as to form a precast cavity for concrete structural members among the precast mold base 1, the mold frame 2, the two mold side plates 5, and the positioning plate 7.

[0023] Further, both the first installation groove 3 and the second installation groove 4 are arranged in a convex structure. The translation groove 12 is communicated with the two second installation grooves 4; it is convenient for the translation plate 13 in the translation groove 12 to move and drive the mold side plate 5 in the second installation groove 4 to move.

[0024] Further, the second translation adjustment mechanism includes a second rotating seat 14, a second threaded rod 15, and a grip plate 16. A second rotating seat 14 is arranged on one inner wall of the translation groove 12. One end of a second threaded rod 15 is rotatably installed on one side of the second rotating seat 14. The other end of the second threaded rod 15 threadedly penetrates outside the translation plate 13 and is fixedly installed with a grip plate 16; by screwing the grip plate 16 on the second threaded rod 15, the length of the two mold side plates 5 extending into the mold frame 2 can be indirectly adjusted.

[0025] Further, a first scale 17 is arranged on one inner wall of the mold frame 2. The first scale 17 is located on one inner wall of the mold frame 2 close to the positioning plate 7; it is convenient to know the height of the concrete injected into the precast cavity.

[0026] Specifically, two second scales 18 are provided on the top side of the mold frame 2, and one side of each of the two mold side plates 5 is respectively attached and pointed at the corresponding scale values on the corresponding second scales 18; by observing the values pointed at by one side of the two mold side plates 5 on the corresponding second scales 18, the lengths of the two mold side plates 5 extending into the mold frame 2 can be known.

[0027] During use: during the prefabrication of concrete structural members, by screwing the grip plate 16 to drive the second threaded rod 15 to rotate, the translation plate 13 is moved in the translation groove 12, and then the two mold side plates 5 are synchronously driven to move in the corresponding first installation groove 3 and the second installation groove 4 until one side of the two mold side plates 5 points at the corresponding values on the second scale 18, completing the length adjustment of the concrete structural member. After that, by screwing the turntable 10 to drive the first threaded rod 9 to rotate, the positioning plate 7 is moved to the left, and the two protruding plates on one side wall of the positioning plate 7 are inserted into the positioning grooves 6 on one side of the two mold side plates 5, so as to form a prefabrication chamber for the concrete structural member between the prefabrication mold base 1, the mold frame 2, the two mold side plates 5 and the positioning plate 7. Then, by pouring concrete into the prefabrication chamber, when the concrete solidifies and forms in the prefabrication chamber, by reversely screwing the turntable 10 on the first threaded rod 9, the positioning plate 7 is moved to the right to be separated from the prefabricated concrete structural member. After that, by reversely screwing the grip plate 16 on the second threaded rod 15, the two mold side plates 5 are driven to move to the left and be separated from the prefabricated concrete structural member. At this time, it is convenient to take out the prefabricated concrete structural member, completing the demolding of the concrete structural member.

[0028] For the prefabrication mold of the concrete structural member in this case, by screwing and adjusting the grip plate 16 on the second threaded rod 15, the translation plate 13 synchronously drives the two mold side plates 5 to move on the two side walls of the mold frame 2. By observing the values pointed at by one side of the two mold side plates 5 on the corresponding second scale 18, the lengths of the two mold side plates 5 on the two side walls of the mold frame 2 are adjusted, forming prefabrication chambers for concrete structural members with different length dimensions, so that prefabricated concrete structural members with different lengths can be realized, avoiding the need to configure and replace mold side plates 5 with different lengths, saving the material cost of accessories, and improving the practicability of the prefabrication mold of the concrete structural member.
