DETAILED DESCRIPTION

[0022] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0023] Please refer to Figs. 1-3 In the embodiments of the present application, a prefabricated concrete part mold for fabricated building comprises a mold assembly 1 composed of an L-shaped template 101 and a steel bar slot 102, the steel bar slot 102 is evenly arranged on the side surface of the vertical part of the L-shaped template 101 and completely penetrates the other side of the vertical part of the L-shaped template 101, the L-shaped template 101 is connected with a support assembly 2 through the steel bar slot 102, and the support assembly 2 is used for providing height support for the embedded steel bar.

[0024] The support assembly 2 comprises a lower support unit and an upper blocking unit.

[0025] The lower support unit is used for providing support for the embedded steel bar passing through the steel bar slot 102, and the upper blocking unit is used for forming blocking for the embedded steel bar.

[0026] The lower support unit comprises an inverted U-shaped support block 201, a connecting block 202, an adjusting bolt 203, a fixed circular block 204 and a fixed screw cylinder 205.

[0027] The fixed screw cylinder 205 is fixed to the top of the horizontal part of the L-shaped template 101 and is horizontally aligned with the steel bar slot 102.

[0028] The connecting block 202 is fixed to one side of the inverted U-shaped support block 201, the inverted U-shaped support block 201 vertically slides in the inner side of the steel bar slot 102 and is sleeved with the vertical part of the L-shaped template 101, the adjusting bolt 203 penetrates from the top of the connecting block 202 to the bottom of the connecting block 202, the fixed circular block 204 is distributed at the bottom of the connecting block 202 and is fixed with the screw rod part of the adjusting bolt 203, and the screw rod part of the adjusting bolt 203 is threadedly connected with the fixed screw cylinder 205.

[0029] By rotating or loosening the adjusting bolt 203 relative to the fixed screw cylinder 205, the height adjustment of the inverted U-shaped support block 201 is realized, and the inverted U-shaped support block 201 is used for providing support for the embedded steel bar.

[0030] The upper blocking unit comprises a blocking plug 206, both end faces of the blocking plug 206 are formed with vertical clamping grooves matched with the vertical part of the L-shaped template 101, and the blocking plug 206 is inserted into the inner side of the steel bar slot 102 through the vertical clamping grooves to form blocking for the space above the embedded steel bar.

[0031] The top of the inverted U-shaped supporting block 201 and the bottom of the plugging plug 206 are formed with an arc-shaped groove matching the outer diameter of the embedded steel bar.

[0032] In the embodiment, it should be noted that the L-shaped template 101 can be assembled into a rectangular frame structure by combining the long side and the wide side of the prefabricated mold, and then assembled into a prefabricated mold of a prefabricated wallboard by cooperating with a bottom plate.

[0033] In use, the inverted U-shaped supporting block 201 is installed inside the steel bar slot 102. When installing the embedded steel bar, the height adjustment bolt 203 can be rotated according to the height requirement between the embedded steel bar and the bottom plate. The height adjustment bolt 203 and the fixed screw cylinder 205 are tightened or loosened, and the height adjustment bolt 203 can drive the connecting block 202 and the inverted U-shaped supporting block 201 to move up and down synchronously through the fixed circular block 204, thereby realizing the height adjustment of the inverted U-shaped supporting block 201. Different heights of the inverted U-shaped supporting block 201 can meet the support requirements of different heights of the embedded steel bar.

[0034] After the height adjustment of the inverted U-shaped supporting block 201 is completed, the embedded steel bar can be laid, and then the corresponding number of plugging plugs 206 are taken out, so that the plugging plugs 206 are inserted from the top of the steel bar slot 102 and finally fit with the upper surface of the embedded steel bar. In this way, not only the height of the embedded steel bar is fixed, but also the height of the embedded steel bar remains stable during pouring of the concrete, and the gap above the steel bar slot 102 is sealed to prevent the concrete from leaking out (it should be noted that the plugging plug 206 has a large frictional resistance with the outer wall of the L-shaped template 101, which can ensure the position of the plugging plug 206 is fixed).

[0035] Please refer to Figs. 1-3 , the vertical part of the L-shaped template 101 is integrally formed with a first protruding block 103, and the two end faces of the L-shaped template 101 are respectively formed with a butt joint groove 104 and a second protruding block 105, and the distribution law of the butt joint groove 104 and the second protruding block 105 matches and is the same as that of the first protruding block 103.

[0036] The two end faces of the L-shaped template 101 are also provided with a connecting hole 106, and the connecting hole 106 is distributed in a staggered manner with the butt joint groove 104 and the second protruding block 105.

[0037] In the embodiment, it should be noted that the L-shaped template 101 has two types, one of which is integrally formed with a butt joint groove 104 and a second protruding block 105 at the two ends, and the other of which is integrally formed with a butt joint groove 104 at the two ends.

[0038] When two adjacent L-shaped templates 101 are spliced, the automatic alignment of the connecting holes 106 can be realized by the butt joint of the butt joint grooves 104 and the second protruding blocks 105, and the relative limiting force of the two L-shaped templates 101 can be effectively enhanced, then the two L-shaped templates 101 can be connected and fixed by penetrating the connecting holes 106 with bolts and screwing the nuts;

[0039] When the L-shaped templates 101 are combined to form a wide side (or a long side) of a mold, the last L-shaped template 101 is selected as the L-shaped template 101 with the butt joint grooves 104 at both ends, so that the wide side formed has the butt joint grooves 104 at both ends, and then when the rectangular frame is combined, the first protruding blocks 105 on the long side are clamped in the butt joint grooves 104 on the wide side, so that the relative limiting force of the long side and the wide side can be further enhanced;

[0040] It should be further pointed out that the mold assembly 1 is a plastic mold, and the fixing between the L-shaped templates 101 and the bottom plate is a prior art structure, which will not be described in detail here.

[0041] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
