Description

Technical Field

[0001] The invention relates to a mold for a prefabricated 3D house, and belongs to the technical field of prefabricated house molds. Background Art

[0002] The existing 3D house is a pentahedral prefabricated house with four walls and a roof prefabricated in the factory. It is cast using a prefabricated concrete house mold. After casting, the mold is removed by a screw rod of the inner mold. The inner top mold also needs to be raised and lowered, making it difficult to remove the mold. The side mold is also easily deformed, which increases the workload. It needs to be re-trimmed when used again, which reduces the service life of the mold.

[0003] Announcement No. CN216732326U, named as a Chinese utility model patent for a mold of a prefabricated integral house, in which the inner top mold, four inner side molds and corner molds (i.e., angle steels) of the inner mold are respectively fixed to the bracket of the bottom mold by screw rods. When removing the mold, personnel enter the bottom mold, loosen the screw rod connected to the inner top mold, so that the sliding sleeve slides downward along the column, and the surface of the inner top mold is separated from the component. Correspondingly, the screw rod connected to the inner side mold is loosened to retract the inner side mold, and the surface of the inner mold is separated from the component. That is, both the inner top mold and the inner mold need to be disassembled, which is costly and laborious, and unsafe for personnel.

[0004] Publication number CN112796509A, named as a Chinese invention application of a prefabricated house mold structure system, when removing the mold, the side molds and corner molds of the inner mold need to be disconnected from all connections, which is labor-intensive and time-consuming; the side molds are first retracted inward, and it is difficult to pull the corner molds inward because the contact surface with the concrete is large, and even external auxiliary knocking is required to remove the mold.

Seat 61; a guide rod support 64 is horizontally installed on the outer side of the column 11 corresponding to the U-shaped inclined groove support 61, and the guide rod 63 is horizontally and vertically installed at the end of the guide rod support 64; the corresponding gaps at both ends of the guide rod 63 are set in the inclined groove 62; when the sliding demolding assembly drives the long inner mold 22, the wide inner mold 23 or the right-angle inner angle mold 24 to demold inward, the roller B54 rolls obliquely downward along the track inclined plate 52, and the U-shaped inclined groove support 61 slides obliquely downward along the guide rod 63 through the inclined groove 62, which can be used as the track for sliding.

[0040] As attached Figure 1 , 14 As shown, the outer mold of the present invention includes two groups of long side molds 701 and two groups of wide side molds 702. An eave 700 is arranged on the outer side of the top of the wide side mold. Tie pillars 703 are installed at intervals on the top of each group of long side molds 701. Tie screws 704 are installed between the tie pillars 703 corresponding to the two groups of long side molds 701 through bolts. The wide side molds are clamped to close the mold to prevent mold expansion, and the tie screws 704 are removed when the mold is removed.

[0041] Sleeves A705 are fixedly installed horizontally from top to bottom on the outside of the side of the long side mold 701, and a threaded pull hook 706 is inserted through the gap of the sleeve A705 and set at the end. A square sleeve B707 corresponding to the sleeve A705 is installed on the side of the wide side mold 702, and a connecting sleeve C708 with a through hole on the outer end is inserted in the inner gap of the square sleeve B707. The end of the pull hook 706 is threaded through the through hole and then fixed with a nut. The two groups of long side molds 701 and the two groups of wide side molds 702 are connected in a square shape, which is convenient for connection and disassembly.

[0042] As attached Figure 1 , 3 As shown in Figures 15, the sliding assembly of the present invention includes a guide rail 709 installed on the outer side of the bottom of the inner support frame 1, a triangular support frame 710 installed at intervals on the outer wall of the long side mold 701 or the wide side mold 702 corresponding to the guide rail 709, and a track wheel 711 rotatably installed on the bottom of the triangular support frame 710; the triangular support frame 710 drives the long side mold 701 or the wide side mold 702 to move on the guide rail 709 through the track wheel 711, which is convenient for pushing and pulling.

[0043] Embodiment 2:

[0044] The difference between this embodiment and the first embodiment is: Figure 1 , 3 As shown in FIG. 15 , the present invention sets an anti-overturning component on the outer side of the bottom of the triangular support frame 710; two triangular support frames 710 are installed at intervals on the outer side of each group of long side molds 701 or wide side molds 702.

[0045] The anti-overturning assembly includes an inclined support plate 712 installed on the outside of the bottom beam of the triangular support frame 710 and an anti-overturning wheel 713 rotatably installed at the end of the inclined support plate 712, and the anti-overturning wheel 713 rotates in the side groove of the guide rail 709. The triangular support frame 710 drives the long side mold 701 or the wide side mold 702 to move on the guide rail 709 through the track wheel 711, and the anti-overturning assembly prevents the triangular support frame 710 from derailing, that is, prevents the long side mold 701 or the wide side mold from tipping over.

[0046] Embodiment three:

[0047] The difference between this embodiment and the first and second embodiments is that: Figure 1 , 3 As shown in Figures 16, a connecting plate A714 is fixedly installed at the end of the guide rail 709 corresponding to the inner support frame 1, a connecting plate B101 corresponding to the connecting plate A714 is installed on the outer side of the bottom of the inner support frame 1, and bolts and nuts are installed in the corresponding long holes of the connecting plates A714 and B101 to facilitate the position adjustment, disassembly and installation of the guide rail 709.

[0048] When the inner mold is disassembled and closed, the nut D41 on the outside of the sliding demolding assembly is rotated to drive the pull rod 33 to rotate inward, and the two thrust ball bearings 36 bear the axial load. The pull rod 33 drives the U-shaped ear seat 32 to move inward in the rectangular groove body 31 and drives the roller A37 to roll in the rectangular groove body 31, so that the connecting rod 34 drives the long inner mold 22, the wide inner mold 23 and the right-angle inner corner mold 24 obliquely downward in sequence through the roller B54 to roll along the track inclined plate 52, and the U-shaped inclined groove support 61 slides obliquely downward along the guide rod 63 through the inclined groove 62 to demold. When closing the mold, the pull rod 33 is rotated outward, and the connecting rod 34 drives the right-angle inner corner mold 24 obliquely upward first, and then drives the long inner mold 22 and the wide inner mold 23 to close the mold. There is no need to operate the inner top mold, which saves time and effort.

[0049] When the outer mold is disassembled or assembled, the pulling screws 704 on the top of the two sets of long side molds 701 are removed or installed, and the pulling hooks 706 of the adjacent long and wide side molds are removed or installed. The triangular support frame 710 is pushed and pulled to drive the long side mold 701 or the wide side mold 702 to move on the guide rail 709 through the track wheel 711, so that the long side mold 701 or the wide side mold is away from or close to the inner mold.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
