DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0021] Please refer to Figures 1 to 3 The utility model provides a kind of technical scheme: a kind of fabricated aluminum alloy formwork, including base 1, vertical pipe 2, inclined strut 3 and supporting plate 4, when using, the bottom of supporting plate 4 and aluminum alloy formwork contact, base 1 and the ground below aluminum alloy formwork contact, supporting plate 4 is connected by vertical pipe 2 and base 1, and inclined strut 3 plays the role of supporting strength.

[0022] In the technical solution, the base 1 comprises a connecting disc 11, a connecting shaft 12, a pad plate 13 and a locking piece 14. The outer periphery of the connecting disc 11 is inserted with three circumferentially distributed pad plates 13. In the embodiment, the three pad plates 13 are circumferentially uniformly distributed relative to the connecting disc 11. The pad plates 13 increase the coverage of the base 1, thereby improving the stability of the base 1. In use, the pad plates 13 are in contact with the ground, and the connecting disc 11 is above the ground. The locking piece 14 is above the connecting disc 11 and is inserted and matched with the connecting disc 11 and the connecting shaft 12. The top of the connecting disc 11 is inserted and connected with the bottom of the stand pipe 2 through the connecting shaft 12. In specific implementation, preferably, the middle part of the top of the connecting disc 11 is fixedly connected with a positioning pipe 113. The connecting shaft 12 is fixedly sleeved with a baffle 121, and the bottom of the baffle 121 is sleeved in the positioning pipe 113. The upper end surface of the baffle 121 abuts against the bottom of the stand pipe 2. That is, when the locking piece 14 is pulled out, the pad plates 13 and the connecting disc 11 can be disassembled. The bottom of the supporting plate 4 is fixedly connected with a positioning shaft 41 which is inserted and matched with the top of the stand pipe 2. The outer peripheral wall of the stand pipe 2 is fixedly provided with an upper baffle 21. The top of the pad plate 13 is fixedly provided with a lower baffle 131. The two ends of the inclined support 3 abut against the upper baffle 21 and the lower baffle 131 respectively. At this time, the entire stand pipe 2 is supported by the three inclined supports 3. The three inclined supports 3 cooperate with the stand pipe 2 to improve the strength and stability of the support of the supporting plate 4. When the locking piece 14 is removed and the supporting plate 4 is pulled out, the inclined supports 3 will automatically disengage from the lower baffle 131 and the upper baffle 21.

[0023] The above-mentioned base 1, stand pipe 2, inclined support 3 and supporting plate 4 of the mold frame and the assembly function of the base 1 itself make the assembly, disassembly, transportation and storage of the mold frame more convenient.

[0024] Specifically, the outer periphery of the connecting disc 11 is provided with a gap 111 which is matched with one end of the pad plate 13. The top of the connecting disc 11 is provided with a limiting hole 112 which is communicated with the gap 111. The bottom of the gap 111 extends to the bottom of the connecting disc 11. The top of the pad plate 13 is provided with a slot 132 which is close to one end. The locking piece 14 comprises a positioning ring 141 and three inserting rods 142 which are located on the outer periphery of the positioning ring 141. The inserting rods 142 are inserted and matched with the limiting hole 112 and the slot 132. Specifically, the three inserting rods 142 pass through the limiting hole 112 on the connecting disc 11 and are simultaneously inserted into the slots 132 on the three pad plates 13. At this time, the pad plates 13 cannot move radially relative to the connecting disc 11 and cannot shake horizontally under the limitation of the gap 111. In addition, a limiting groove can be formed in the gap 111 close to the axis of the connecting disc 11. An inserting plate which is inserted and matched with the limiting groove is welded on one end of the pad plate 13. The pad plate 13 is in a state of zero degree of freedom under the limitation of the inserting rods 142, the inserting plate and the limiting groove.

[0025] In the embodiment, the upper stopper 21 comprises a positioning disc 211 and upper U-shaped seats 212. The positioning disc 211 is fixedly sleeved outside the stand pipe 2, and the upper U-shaped seats 212 are fixedly arranged at the bottom of the positioning disc 211. The opening end of the upper U-shaped seat 212 faces downward, and the number of the upper U-shaped seats 212 is three and they are circumferentially distributed relative to the stand pipe 2. The three upper U-shaped seats 212 are circumferentially uniformly distributed relative to the stand pipe 2. The lower stopper 131 comprises a lower U-shaped seat 1311, which is fixedly arranged at the top of the pad plate 13 and has an opening end facing the stand pipe 2. In use, the two ends of the diagonal brace 3 are respectively inserted into the upper U-shaped seat 212 and the U-shaped groove of the upper U-shaped seat 212.

[0026] Further, the bottom of the connecting shaft 12 is screw-connected with the positioning pipe 113, that is, the lower segment of the connecting shaft 12 is in a screw structure, and the positioning pipe 113 is in a thread sleeve structure. The lower stopper 131 comprises a bolt 1312 which penetrates and is screw-connected with the non-opening end of the lower U-shaped seat 1311. One end of the bolt 1312 abuts against the bottom of the diagonal brace 3. When the rotation of the connecting shaft 12 is controlled, the stand pipe 2 can be lifted and lowered, and the height of the supporting plate 4 can be controlled. When the bolt 1312 is screwed, the diagonal brace 3 is in a stressed state. The purpose is that when the supporting plate 4 is lifted and lowered, the diagonal brace 3 can be in an effective supporting state.

[0027] The outer circumferential wall of the connecting shaft 12 is provided with a driving hole 123 below the stop disc 121. The driving hole 123 is an operation hole for controlling the rotation of the connecting shaft 12. In use, a crowbar is inserted into the driving hole 123, and then the crowbar is pushed to drive the connecting shaft 12 to rotate. This has the effect of making it more convenient to control the rotation of the connecting shaft 12. The positioning ring 141 is gap-sleeved outside the stand pipe 2 and is axially slidably detachably connected. This arrangement avoids the stand pipe 2 from being rotated by the connecting shaft 12 by using friction. In specific implementation, a sliding groove can be formed in the inner wall of the positioning ring 141, and a guide strip which passes through the sliding groove is welded to the outer wall of the stand pipe 2. After the stand pipe 2 is detached, the positioning ring 141 is slid toward the bottom end of the stand pipe 2 to be separated from the stand pipe 2.

[0028] In the embodiment, the top of the supporting plate 4 is provided with a connecting hole 42. The connecting hole 42 is provided to facilitate the installation of a butt plate. The purpose is to adapt to the support of aluminum alloy formworks of different specifications. The structure of the butt plate is determined according to the specification of the aluminum alloy formwork which needs to be supported and fixed.

[0029] Working principle: when the need to disassemble the template for supporting the fixed aluminum alloy template, first use wrench to loosen the bolt 1312, one end of the bolt 1312 away from the bottom of the inclined support 3, at this time can easily take off the inclined support 3, then control the reverse of the interface shaft 12, the interface shaft 12 height is reduced, the riser 2 is lowered, the supporting plate 4 is lowered and separated from the bottom of the aluminum alloy template, at this time the positioning ring 141 and the riser 2 are lifted, the riser 2 is separated from the interface shaft 12, the plug rod 142 is pulled out, the disassembly of the riser 2 is realized, then the positioning ring 141 is slid off the riser 2, finally the gasket 13 and the positioning shaft 41 are pulled out, at this time the whole aluminum alloy template is disassembled into each regular component occupying small space.

[0030] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.
