Description

Technical Field

[0001] The utility model relates to a revolving cushion block which can adapt to the height of a hanging formwork and belongs to the technical field of building construction auxiliary tools. Background Art

[0002] In the design of commercial podium construction, the outer beam of the podium is usually higher than the building elevation of the slab. The conventional construction method is to use a hanging formwork to ensure that the beam and slab can be poured with concrete at the same time. The hanging formwork method is generally used in places where there is a height difference between the pouring heights on both sides. Compared with other formwork reinforcement methods, its lower mouth has no fixed support, and lateral reinforcement is used to ensure its stability. The lower part uses mortar pads to support the formwork to ensure its building elevation. However, the conventional mortar pads have a small contact area with the bottom of the hanging formwork, insufficient strength, and cannot be adjusted according to the height of the hanging formwork.

[0016] Figure 2 This is a schematic diagram of the support plate and sleeve structure in Example 2 of the utility model. DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] The reference numerals in the drawings of the specification include: base 1, sleeve 2, screw 3, sleeve 4, support plate 5, first support plate 51, second support plate 52, first adjusting bolt 53, slide plate 54, second adjusting bolt 55, slide groove 56, groove 6.

[0019] Embodiment 1:

[0020] A revolving spacer that can adapt to the height of the hanging mold, such as Figure 1 As shown, it includes a base 1, a screw 3, a sleeve 2, a sleeve 4 and a support plate 5. The base 1 is a truncated cone and is cast by concrete. The screw 3 is coaxially fixed to the upper end of the base 1. The sleeve 2 is sleeved on the outer periphery of the screw 3 and placed on the base 1. The sleeve 4 is threadedly connected to the upper end of the screw 3. The inner and outer diameters of the sleeve 2 are consistent with the inner and outer diameters of the sleeve 4. The function of the sleeve 2 is to isolate the sleeve 4 from the base 1. The support plate 5 is horizontally fixed to the top of the sleeve 4. The upper end surface of the support plate 5 is provided with a groove 6 that cooperates with the hanging mold, and the groove 6 is used to fix the hanging mold.

[0021] By rotating the sleeve 4 relative to the screw rod 3, the sleeve 4 can be rotated up and down relative to the base 1, thereby adjusting the height of the support plate 5, so as to match the hanging molds of different heights. The contact area is increased by the support plate 5 and the hanging mold; in addition, the overall structure is firm and the support strength is good.

[0022] In this embodiment, the sleeve 4 and the support plate 5 are made of stainless steel, and the sleeve 2 is made of plastic.

[0023] The base 1 is made in advance by using a mold and concrete, and the screw 3 is pre-buried in the base 1. During the implementation process at the construction site, the sleeve 2 is inserted into the screw 3, and the sleeve 4 is rotated clockwise, and the sleeve 4 is moved downward and inserted into the screw 3 to form a whole with the base 1. The upper end of the sleeve 2 fits the sleeve 4 to achieve the isolation of the sleeve 4 from the concrete base. According to the height of the beam hanging formwork at the construction site, the sleeve 4 is adjusted to move up and down to reach the specified building elevation, so that the hanging formwork can be stably supported inside the groove 6 at the upper end of the support plate 5. After the concrete pouring is completed and reaches the designed strength, the hanging formwork is removed, and then the sleeve 4 is rotated counterclockwise and moved upward to separate the support plate 5 from the base 1, so as to achieve the purpose of the turnover and recycling of the support plate 5.

[0024] Example 2

[0025] The difference between Example 2 and Example 1 is that: Figure 2 As shown, the support plate 5 includes a first support plate 51 and a second support plate 52 aligned with each other from bottom to top, the first support plate 51 and the second support plate 52 are both steel plates, the first support plate 51 is fixed to the upper end of the sleeve 4, and a first adjusting bolt 53 is threadedly connected to the left and right parts of the first support plate 51 respectively, the first adjusting bolt 53 vertically penetrates the first support plate 51 upward and is rotatably connected to the second support plate 52; the second support plate 52 is moved up and down relative to the first support plate 51 by screwing the first adjusting bolt 53;

[0026] Since it is impossible to ensure that the hanging mold is exactly in the groove 6 when the height of the support plate 5 reaches the requirement during the process of rotating the sleeve 4, and the groove 6 and the hanging mold may be misaligned, therefore, in this embodiment, the height of the support plate 5 is adjusted by rotating the sleeve 4 to a height close to the target height but the groove 6 is exactly parallel to the hanging mold, and then the height of the second support plate 52 is achieved to the target height by screwing the first adjusting bolt 53, at which time it can be ensured that the hanging mold is exactly in the groove 6.

[0027] like Figure 2 As shown, the vertical cross-section of the second support plate 52 is U-shaped, and two slide plates 54 are slidably connected to the middle upper end of the second support plate 52, and a T-shaped slider is fixed to the lower end of the slider 54. A T-shaped slide groove 56 extending in the horizontal direction is provided at the middle upper end of the second support plate 52. The T-shaped slider is inserted into the T-shaped slide groove 56 and can slide left and right along the T-shaped slide groove 56, so that the slide plate 54 can only slide left and right along the second support plate 52. A second adjusting bolt 55 is threadedly connected to each of the two ends of the second support plate 52, and the second adjusting bolt 55 horizontally passes through one end of the second support plate 52 and is rotatably connected to the corresponding slide plate 54. The gap between the two slide plates 54 forms a groove 6.

[0028] The second adjusting bolt 55 is screwed to drive the slide plate 54 to slide left and right, so that the distance between the two slide plates 54 can be adjusted, so as to adapt to hanging molds of different widths and clamp the hanging molds, thereby better supporting and fixing the hanging molds.

[0029] The above description is only a specific implementation method of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present utility model, which should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
