Description

FIELD

The present disclosure relates to a stilt device, and more particularly relates to a supporter.

BACKGROUND

Supporters are applied to fields such as waterscape fountains, balcony gardens, and square paving, e.g., stilting a WPC (Wood- Plastic Composites) or metal keel, and supporting a raised stone floor, etc. Particularly, for the sake of water drainage, a constructed road surface or top layer will be sloped to avoid water accumulation. Although the slope is relatively small, construction quality issues such as uneven and displaced floor tiles easily occur when typical or universal supporters are used.

An objective of the present disclosure is to provide a supporter adapted to stilting woodwork plates, ceramic tiles, and stonework like marble to be paved on a sloped ground surface.
To achieve the objective above, the present disclosure adopts the following technical solution: a slope-adjustable supporter, comprising: a base, a support plate, and a height-adjusting part that is disposed between the base and the support plate to adjust a height of the support plate through thread fit, a top portion of the height-adjusting part being provided with a recessed arc surface, a bottom portion of the support plate being provided with a convex arc surface, the convex arc surface being supported inside the recessed arc surface and being slidable relative to the recessed arc surface.
Preferably, the height-adjusting part comprises a screw having the recessed arc surface, a center of the support plate being provided with a through-hole, a center of the screw being provided with a convex column protruding above the recessed arc surface, a center of the convex column being provided with a plug hole into which a wrench driving the screw to rotate is insertable.
Preferably, an anti-rotation plug preventing a relative rotation is disposed between the support plate and the screw.
Preferably, catch positions are evenly distributed at an outer wall of the convex column along a peripheral direction, the anti-rotation plug is provided with catch bosses for being caught into the catch positions, and the anti-rotation plug is provided with a plug pin for being plugged into the plug hole.
Preferably, positioning convex ribs distributed in a cross shape are provided at a top face of the support plate around a center of the top face.
Preferably, a rubber gasket is provided on the support plate.
Preferably, a material-saving recessed groove is opened in an upper plane of the support plate.
The technical solution of the present disclosure mainly involves horizontal adjustment and height adjustment of the plastic supporter, wherein the height adjustment scheme achieves change of the product height by rotating male and female threads of the height adjustment part, and the horizontal adjustment scheme achieves horizontal adjustment in such a manner as: providing a recessed arc surface at a top portion of the height adjustment part, and providing a convex arc surface at a bottom portion of the support plate, the convex arc surface of the support plate being slidable within a certain range in the recessed arc surface of the top portion of the height adjustment part, such that when the product is placed on a ground surface with a certain slope, due to gravity or external force, sliding of the support plate will cause a change to the included angle between the support plate and the ground surface, and by calibration with a tool, supported faces may become horizontal. Under a certain slope, combination of the horizontal adjustment and height adjustment enables the top surfaces of supporters at different positions to a same horizontal height, such that after stonework slabs are paved thereon, the mounted plates may also be horizontal due to the principle of stress equilibrium. Therefore, the supporter in this technical solution enables stilting of slabs and stonework tiles on a sloped ground surface and enables the mounted slabs and stonework tiles to meet designed standards.

DETAILED DESCRIPTION OF EMBODIMENTS

As illustrated in Figs. 1 and 2, a slope-adjusted supporter 1 is provided, comprising a base 10, a support plate 13, and a height adjustment part disposed between the base 10 and the support plate 13 to adjust a height of the support plate through thread fit, the support plate 13 being slidable relative to the height adjustment part.
Particularly, the height adjustment part comprises a screw 12. To implement relative sliding between the support plate 13 and the screw 12, a recessed arc surface 122 is provided at a top portion of the screw, a convex arc surface 134 is provided at a bottom portion of the support plate, and the convex arc surface 134 is supported inside the recessed arc surface 122 to implement the relative sliding.
As illustrated in Fig. 3, before adjustment of the support plate 13 and the screw 12, an upper plane of the support plate is parallel to a lower plane of the base. As illustrated in Figs. 4 and 7, after the supporter is placed on a sloped face, due to its own gravity or external force, an included angle between the upper plane of the support plate and the sloped face will change after the convex arc surface 134 supported in the recessed arc face 122 has a relative slide, and the upper plane of the support plate may be calibrated to be horizontal through a level gauge.
As illustrated in Fig. 2, to facilitate adjusting the height of the screw 12, a center of the support plate is provided with a through-hole 132, a center of the screw is provided with a convex column 123 protruding above the recessed arc surface. The convex column functions to limit a movable range of the support plate and prevent the supporter from sliding off. A center of the convex column is provided with a plug hole 1231. As illustrated in Fig. 5, a wrench 16 driving the screw 12 to rotate may be inserted in the plug hole 1231. The wrench 16 is in a T shape, a head portion of which has a drive head 161, the drive head 161 being inserted into the plug hole 1231, rotation of the wrench 16 drives rotation of the screw 12 to thereby implement height adjustment of the screw 12. Of course, those skilled in the art may understand that the drive head 161 and the plug hole 1231 may have a variety of shapes, e.g., an elongated bar shape adopted in this embodiment, or various kinds of polygonal shapes.
If the supporter is applied to a smooth ground, the support plate 13 needs to be locked to limit sliding of the support plate 13; therefore, an anti-rotation plug 15 preventing relative rotation therebetween is disposed between the support plate 13 and the screw 12. Catch positions 1232 are evenly distributed at an outer wall of the convex column along a peripheral direction. The anti-rotation plug 15 is provided with a catch boss 152 for being caught in the catch positions 1232 and a plug pin 151 for being plugged in the plug hole 1231, wherein positioning of the anti-rotation plug 15 is implemented by plugging the plug pin 151 into the plug hole 1231, such that the anti-rotation plug 15 will not be displaced freely; and the catch boss 152 being caught in the catch position 1232 achieves the objective of limiting the support plate from sliding.
As illustrated in Fig. 6, the present disclosure is mainly applied to support a ground tile 2, wherein positioning convex ribs 131 distributed in a cross shape are provided at a top face of the support plate around a center of the top face. Corners of the floor tile are positioned by the positioning convex ribs, which facilitates paving and positioning of the floor tile. The positioning convex ribs 131 may be snapped or cut off. For example, when the floor tiles are completely paved for final finish, the positioning convex ribs 131 may be removed.
As a further improvement to the present embodiment, a rubber gasket 14 is provided on the support plate 13, for achieving sufficient contact between the floor tile and the supporter as well as a slide-proof. A wrench via-hole 141 is provided at a center of the rubber gasket for the wrench 16 to pass through to thereby adjust rotation of the screw 12. Of course, when the anti-rotation plug 15 is provided, it is also available for the anti-rotation plug 15 to pass through. Moreover, a bar-shaped hole 142 for the positioning convex ribs 131 to pass through is provided at the rubber gasket 14 surrounding the wrench via-hole.
Further, a material-saving groove 133 is opened in the upper plane of the support plate. The material-saving groove is disposed to correspond to a bottom portion convex arc surface of the support plate, which may reduce consumption of the material, reduce weight, and lower cost, without affecting the strength of the support plate per se.
In this embodiment, the height adjustment part further comprises an adjusting disc 11 having a screw part 111. A center of the adjusting disc is hollow and provided with an inner thread fitted to the screw 12, the base 10 is provided with a threaded sleeve part 101 having an inner thread, the inner thread of the threaded sleeve part being fitted with the external thread of the screw part. In this way, height may be adjusted through thread fitting between the adjusting disc 11 and the screw 12 and between the adjusting disc 11 and the base 10. Particularly, the wrench 16 drives the screw 12 to rotate, for adjusting a relative height between the screw 12 and the adjusting disc 11, while the relative height between the adjusting disc 11 and the base 10 is adjusted manually; therefore, provision of both of the adjusting disc 11 and the screw 12 may expand a height adjustment scope of the supporter.
The screw sleeve part 101 of the base is disposed on a base plate 102. To secure the supporter, a fixing hole 1021 for a screw to penetrate through is provided on the base plate 102 so as to fix the base plate. A reinforcing rib 103 is provided between the threaded sleeve part 101 and the base plate 102.
