Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a post-cast strip supporting device. Background Art

[0002] Post-cast strips are designed to prevent harmful cracks in reinforced concrete structures due to uneven shrinkage or settlement. In accordance with design or construction specifications, concrete strips are left at corresponding positions of foundation slabs, walls, and beams. During the construction of post-cast strips, supporting devices are usually required to support the post-cast strips to prevent them from deformation and collapse.

DETAILED DESCRIPTION

[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0029] See also Figure 1-5 The present invention provides a technical solution: a post-cast strip support device. The device comprises a base 110, on which are mounted four sets of fixing components for fixing the support device, a lifting component for adjusting the height of the support device, a supporting component for supporting the post-cast strip mounted on the lifting component, and an adjusting component for adjusting the supporting range of the supporting component mounted on the supporting component;

[0030] The fixing component includes a first movable groove 210, which is opened at the bottom of the base 110. A first threaded rod 220 is rotatably connected to the top inner wall of the first movable groove 210. A movable rod 240 is threadedly connected to the first threaded rod 220. A ball head shaft 241 is installed at one end of the movable rod 240. A ball head seat 251 is hinged on the ball head shaft 241. A base plate 250 is installed on the ball head seat 251. One end of the first threaded rod 220 passes through the base 110, and one end of the first threaded rod 220 is installed with a first turning handle 230.

[0031] When the support device is fixed, the first handle 230 is rotated to cause the first handle 230 to rotate the first threaded rod 220. The rotation of the first threaded rod 220 drives the movable rod 240 to move vertically, and the movable rod 240 drives the bottom plate 250 to move vertically, so that the bottom plate 250 contacts the ground. By adjusting the height of the four sets of bottom plates 250 and the ground, the base 110 is kept horizontal. Under the hinged action of the ball head shaft 241 and the ball head seat 251, when the bottom plate 250 contacts the inclined ground, the movable rod 240 and the bottom plate 250 rotate, so that the bottom plate 250 is in contact with the ground. At the same time, the base 110 is also in a horizontal position, and the contact area between the bottom plate 250 and the ground is not reduced, making it difficult to clean the base 110, thereby not affecting the use of the support device.

[0032] A first guide block 242 is installed on the moving rod 240 . A first guide groove 211 is defined in the first moving groove 210 . A first guide rod 212 is installed in the first guide groove 211 . The first guide rod 212 and the first guide block 242 are slidably connected.

[0033] The arrangement of the first guide block 242 and the first guide rod 212 allows the moving rod 240 to remain stable during the vertical movement, so that the moving rod 240 will not rotate along with the first threaded rod 220 .

[0034] The lifting assembly includes a fixed column 310, which is mounted on the base 110. A partition 320 is installed within the fixed column 310. A second threaded rod 330 is rotatably connected to the partition 320. A first gear 331 is mounted on one end of the second threaded rod 330. A movable rod 340 is threadedly connected to the other end of the second threaded rod 330. A second guide block 341 is mounted on one end of the movable rod 340. The second guide block 341 is slidably connected to the fixed column 310. A connecting block 342 is mounted on the other end of the movable rod 340. A rotating rod 350 is rotatably connected to the side wall of the fixed column 310. A second gear 351 is mounted on one end of the rotating rod 350, which meshes with the first gear 331. A second turning handle 352 is mounted on the other end of the rotating rod 350.

[0035] When adjusting the height of the support device, the second handle 352 is turned, causing the second handle 352 to rotate the rotating rod 350, which in turn causes the rotating rod 350 to rotate the second gear 351. Under the meshing action of the second gear 351 and the first gear 331, the second threaded rod 330 rotates, causing the second threaded rod 330 to drive the movable rod 340 to move vertically, and the movable rod 340 to drive the first support plate 410 to move vertically, thereby adjusting the height of the support device. The second guide block 341 is rectangular, allowing the second guide block 341 to move vertically within the fixed column 310, so that the movable rod 340 does not rotate with the second threaded rod 330.

[0036] The support assembly includes a first support plate 410, a connecting base 420 is installed at the bottom of the first support plate 410, a card slot 421 is provided on the connecting base 420, the card slot 421 is engaged with the connecting block 342, a second guide groove 430 is provided on the connecting base 420, a second guide rod 431 is installed in the second guide groove 430, a baffle 440 is slidably connected to the second guide rod 431, a first magnet 441 is installed on the top and bottom of the baffle 440, a third magnet 451 is installed at the bottom of the first support plate 410, a second magnet 450 is installed on the connecting base 420, and the third magnet 451 and the second magnet 450 are respectively used in conjunction with two groups of first magnets 441.

[0037] The connecting block 342 is snapped onto the connecting seat 420, facilitating replacement of the first support plate 410. A baffle 440 is provided to limit the connecting block 342, preventing the connecting block 342 and the connecting seat 420 from falling off during use of the first support plate 410. When the first support plate 410 needs to be disassembled, the baffle 440 is pulled to move it vertically, releasing the limit on the connecting block 342, thereby facilitating separation of the connecting block 342 and the connecting seat 420 and disassembly of the first support plate 410, thereby reducing the time required to disassemble the first support plate 410. The baffle 440 is fixed by the first magnet 441, the second magnet 450, and the third magnet 451, ensuring that the baffle 440 remains stable during use.

[0038] The adjustment assembly includes a second movable slot 510, which is provided on the first support plate 410. A fixed plate 520 is mounted within the second movable slot 510. A bidirectional threaded rod 530 is rotatably connected to the fixed plate 520. A worm gear 540 is mounted on the bidirectional threaded rod 530. Both ends of the bidirectional threaded rod 530 are threadedly connected to movable blocks 570. Two sets of movable blocks 570 are slidably connected within the second movable slot 510. A second support plate 580 is mounted on both sets of movable blocks 570. A worm 560 is rotatably connected to the side wall of the first support plate 410. The worm 560 meshes with the worm gear 540. A third turning handle 561 is mounted on one end of the worm 560.

[0039] When adjusting the support range of the first support plate 410, by rotating the third handle 561, the third handle 561 drives the worm 560 to rotate, and under the meshing action of the worm 560 and the worm wheel 540, the bidirectional threaded rod 530 rotates, and the bidirectional threaded rod 530 drives the moving block 570 to move, and the moving block 570 drives the second support plate 580 to move, thereby adjusting the support range of the support device, improving the convenience of adjusting the support range of the support device, and at the same time allowing the support range of the support device to be adjusted in real time.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
