Description

Adjustable plate support

Technical Field

The application relates to an adjustable plate support for supporting various building plates.

Background

Various plate supports are used for supporting plates in factory buildings, houses and other places. For example, on a foundation or a floor, the sheet material can be laid above the ground by using the sheet material support, so that an elevated building structure layer, such as a floor, a bed and the like, is formed by using the sheet material. And water, electricity, gas, communication and heating pipelines and the like can be discharged in the space below the plate.

One type of sheet metal bracket is highly fixed. Such sheet supports are typically provided in a series of sizes, each size having a fixed height, and the user may select the size of the sheet support based on the desired sheet height. The plate support has a simple structure, but is difficult to realize any plate height, and the leveling operation after the plate is paved is difficult.

Another type of sheet metal bracket is highly variable. Such sheet supports are also provided in a series of sizes, each size having an adjustable height range. With the plate support, the plate can be supported at any height. However, existing adjustable sheet material supports typically have a single height adjustment mechanism. After the board is laid, the board has restrictions on the height adjustment mechanism, and thus it may be difficult to level the board using the height adjustment mechanism. Therefore, it is necessary to precisely level the supporting height of each panel bracket and then lay the panels, or lay the panels while leveling the panels. In any leveling method, there is a problem that the construction efficiency is difficult to improve.

Detailed Description

Some possible embodiments of the present application are described below with reference to the drawings. It should be noted that the figures are not drawn to scale. Some details may be exaggerated for clarity and some details not necessarily shown may be omitted.

The present application relates generally to an adjustable panel bracket (or simply adjustable bracket) that provides an adjustable support height to support a building panel at a desired height. The adjustable support may be provided in a variety of sizes, each size having a corresponding range of adjustable support heights.

One possible embodiment of the adjustable support 100 of the present application is shown in fig. 1, 2. As shown in the drawings, the adjustable support 100 mainly includes: a base 1; a riser 2 defining a central axis, the lower end of the riser 2 being riveted to the base 1 and having the ability to rotate about said central axis relative to the base 1, the upper end of the riser 2 having an internal thread formed therein; a screw 3 having an external thread adapted to engage with the internal thread of the riser 2 along all or most of the height (i.e., length) so that the screw 3 can be screwed into the riser 2 from the upper end of the riser 2 and the height at which the screw 3 emerges from the riser 2 is adjusted by relative rotation between the screw 3 and the riser 2; a nut 4 with an elastic washer screwed on the screw 3 for screwing against the upper end of the stem 2 to lock the screw 3 with respect to the stem 2; a support sleeve 5 screwed to the screw 3 above the nut 4, the axial position (i.e., height) of the support sleeve 5 on the screw 3 being adjustable by rotation of the support sleeve 5 relative to the screw 3; a support plate 6 supported by the support sleeve 5 and fixed to the support sleeve 5; a nut 7 with an elastic washer and a flat washer is screwed to the screw rod 3 for axially locking the support plate 6 between the nut 7 and the support sleeve 5 and for fixing the support sleeve 5 to the screw rod 3.

Possible configurations of the main components of the adjustable support 100 are shown in fig. 3-9.

First, fig. 3-5 show a possible configuration of the base 1. The base 1 is stamped from sheet metal and has a flat base 11 and a raised portion 12 offset upwardly relative to the base 11 at the middle of the base 11. The bulge portion 12 has a central through hole 13 formed therein for being inserted therethrough by a lower end edge portion of the stand pipe 2 so as to be caulked with the base 1. The base 11 has formed therein a number of mounting holes 14 distributed around the ridge 12. The mounting holes 14 may be of different sizes for attachment of different sized fasteners such as cement nails/expansion bolts/screws to the support surface.

The base 11 is adapted to be supported on a support surface (e.g., a floor) for laying the building boards and may have various shapes, such as circular (fig. 4), square (fig. 5), etc., suitable for supporting and arranging on the support surface. The non-circular base 11 is beneficial for positioning each mounting hole 14 during construction. For example, fastener locations for multiple adjustable brackets 100 may be marked or formed uniformly on the support surface in advance. For a circular base 11, locating features may also be formed on the base 11 to facilitate location of each mounting hole 14 on a support surface.

For support surfaces that are not suitable for fasteners, the base 1 may be secured to the support surface with an adhesive applied to the bottom surface of the base 11. Excess adhesive may be squeezed into the mounting holes 14 and may spill somewhat, which contributes to the strength of the connection of the base 1 on the support surface.

One possible construction of the riser 2 is shown in fig. 6. The riser 2 may be machined from metal tubing (including extrusion processes). The riser 2 comprises: a body portion 21, a lower portion 22 located below the body portion 21 and having an increased diameter relative to the body portion 21, and an upper portion 25 located above the body portion 21 and having a reduced diameter relative to the body portion 21. The lower portion 22 is riveted to the base 1 at the lower end thereof, and in one specific way, a ring of bulge 23 is formed on the lower portion 22, an outward flange 24 is formed on the lower edge of the lower portion 22, and the inner peripheral edge of the bulge 12 of the base 1 is axially clamped between the bulge 23 and the flange 24. The upper portion 25 has an internal thread formed therein for engagement with the external thread of the screw 3.

The diameter change in the riser 2 can be achieved by extrusion.

Depending on the specifications of the adjustable support 100, the risers 2 have different heights (lengths), mainly depending on the axial length of the body portion 21. Of course, for the smallest sized riser 2, the body portion 21 may be eliminated such that the upper portion 25 directly engages the lower portion 22.

The lower portion 22 is pressed so as to form at least one pair of clamping planes 26 circumferentially distributed and located opposite each other on the outer periphery. An operator can use a tool such as a wrench to catch on the gripping surface 26 (or simply grasp the gripping surface 26 by hand) to rotate the riser 2 relative to the base 1.

It will be appreciated that the clamping plane 26 may also be formed at other locations of the riser 2.

The riser 2 and the base 1 are fitted at a riveting point which allows mutual rotation between the riser 2 and the base 1. To rotate the stand pipe 2 relative to the base 1, the stand pipe 2 needs to be screwed in order to overcome a screwing torque. The amount of the tightening torque may be selected based on the specifications of the adjustable bracket 100, the application, and the like. For example, the screwing torque may be between 0 and 10 nm, preferably between 0 and 5 nm.

As shown in fig. 7, one possible screw 3 has a body portion 31, and the entire body portion 31 is formed with an external thread. Further, a protruding screw part 32, such as a square head, a hexagonal head, or the like, for holding a tool such as a wrench or the like is formed on the upper end of the main body part 31. An operator can use a wrench to catch on the screw head 32 to turn the screw 3 relative to the riser 2. As another possible structure, as shown in fig. 8, a recessed screw portion 32, such as a quadrangular groove, a hexagonal groove, a straight groove, or the like, into which a tool such as a plug-type wrench can be inserted, is formed in the upper end of the body portion 31. An operator can insert a plug wrench into the screw 32 to turn the screw 3 relative to the riser 2.

Further, for smaller diameter screws 3, they may be solid. If the screw 3 is of a larger diameter, it may be hollow.

One possible construction of the support sleeve 5 is shown in fig. 9 and includes a flat support flange 51 and a skirt 52 extending upwardly from the middle of the support flange 51. The cylindrical portion 52 has an internal thread formed therein for engagement with the external thread of the screw 3. Screw holes 53 may be formed in the support flange 51 for fastening the support flange 51 and the support plate 6 together with screws passing through the screw holes 53 (and/or with an adhesive). In the assembled state, the support flange 51 is perpendicular to the central axis.

The internal thread in the support sleeve 5 is of the same direction as the internal thread in the riser 2. In this way, by turning the clamping portion 26 of the riser 2, with the nut 7 locked, a quick adjustment of the axial distance between the support sleeve 5 and the support plate 6 and the riser 2 can be achieved. With the nut 4 locked, by turning the screw part 32 of the screw 3, a precise adjustment (fine tuning) of the axial distance between the support sleeve 5 and the support plate 6 and the riser 2 can be achieved.

The support plate 6 is a plate body of wood/metal/resin/other material having a certain thickness and length and width (radial) dimensions, and is formed with a hole at the middle portion thereof so as to fit over the cylindrical portion 52 of the support sleeve 5, and the support plate 6 is supported by the support flange 51. The outer contour shape of the support plate 6 may be circular, square, hexagonal, etc. The upper surface of the support plate 6 is adapted to support a building board. The distance between the lower surface of the building board supported by the adjustable bracket 100 and the supporting surface is defined as the supporting height of the adjustable bracket 100.

As an alternative connection between the support sleeve 5 and the support plate 6, the support sleeve 5 can be directly fitted and fixed in the support plate 6 without using screws, as shown in fig. 10.

As an alternative connection between the support sleeve 5 and the screw 3, as shown in fig. 11, a reduced diameter shaft portion 33 having a reduced diameter with respect to the main body portion 31 and not having a thread may be formed at the upper end of the main body portion 31 of the screw 3, and the support sleeve 5 having no internal thread is fitted over the reduced diameter shaft portion 33 and supported by a shoulder created between the reduced diameter shaft portion 33 and the main body portion 31. The reduced diameter shaft portion 33 is formed at its upper end with a threaded portion 34 of reduced diameter relative thereto for engagement with the nut 7. The threaded portion 34 may have a male threaded portion 32 formed thereon (a female threaded portion 32 may also be formed in the threaded portion 34).

As an alternative to the support sleeve 5 and the support plate 6 in the adjustable support 100, a substantially flat support plate (top plate) 8 may be riveted to the upper end 35 of the screw 3, as shown in fig. 12. The support plate 8 may be a metal piece. In the assembled state, the support plate 8 is perpendicular to the central axis. The upper surface of the support plate 8 is adapted to receive a support strip. Screw holes 81 may be formed in the support plate 8 for fastening the support strip to the support plate 8 with screws (and/or with an adhesive).

As a further alternative to the support sleeve 5 and the support plate 6 in the adjustable support 100, an angled support plate (top plate) 9 may be riveted to the upper end 35 of the threaded rod 3, as shown in fig. 13. The angular support plate 9 may be a metal piece having a transverse portion 91 and a longitudinal portion 92 perpendicular to each other. In the assembled state, the transverse portion 91 is perpendicular to the central axis. The upper surface of the transverse portion 91 and the inner surface of the longitudinal portion 92 are adapted to be abutted by the support strip. To this end, screw holes 93 may be formed in the transverse portion 91 and the longitudinal portion 92 for fastening the support strip to the gusset 9 by means of screws (and/or by means of an adhesive).

Other aspects of the adjustable support 100 of fig. 12 and 13 are the same as or similar to the embodiment of fig. 1 and 2 and will not be described in detail.

The various parts of the adjustable support 100 can be specifically designed according to specific needs.

Fig. 14 and 15 show a possible way of using the adjustable support 100 of fig. 1 and 2. A plurality of adjustable supports 100 may be arranged in a matrix and fixed at the base 1 to a support surface by means of fasteners and/or adhesives or the like. The building board 200 is supported at its corners by the support plates 6 of the adjustable bracket 100.

In order to give way to the upper end of the screw 3 of the adjustable bracket 100, the corners of the building boards 200 are chamfered, so that a space 201 is created between the corners where each building board 200 is laid. The outer shape of the building board 200 may be triangular, square, rectangular, hexagonal, etc., as long as a complete structural layer can be formed by splicing a plurality of building boards 200. Each building panel 200 may be supported at its respective corners by a respective adjustable bracket 100, for example, in the case of square or rectangular building panels 200, each building panel 200 may be supported at its four corners by a respective adjustable bracket 100. On the other hand, each adjustable bracket 100 may simultaneously support the corners of a plurality of building boards 200.

After the building boards 200 are laid, additional boards 210, such as decorative boards, may be laid on top of the building boards 200, if necessary, as shown in fig. 14. Of course, in some applications, only the building board 200 itself may be sufficient.

Further, as shown in fig. 16, if necessary (especially when there is no additional panel above the building panel 200), a filler block 202 may be filled in a space 201 between corners of the building panel 200 to close the space 201.

In laying the building board 200, the adjustable bracket 100 may be installed as follows. First, each adjustable support 100 is fixed to a support surface at the base 1 by a fastener and/or an adhesive or the like. The screw 3 is then locked with respect to the riser 2 by means of the nut 4.

The support plate 6 is then, if necessary, pressed and the riser 2 is turned with the screw 3 relative to the base 1 by means of a wrench catching on the clamping plane 26 (or gripping the clamping plane 26 by hand) in order to quickly adjust the axial distance between the support sleeve 5 and the support plate 6 and the riser 2, thus achieving a quick adjustment of the support height of the adjustable support 100 to a predetermined value. As shown in fig. 17.

Next, the building boards 200 may be laid on the support plate 6. After all or a certain number of the building boards 200 are laid, the surface flatness of the laid building boards 200 is measured as a whole. If necessary, the nut 7 is first loosened from above, and then the screw 3 is screwed with respect to the support sleeve 5 and the support plate 6 at the male screw part 32 (or the female screw part 32) by using a wrench so as to precisely adjust the axial distance between the support sleeve 5 and the support plate 6 and the riser 2, as shown in fig. 18, thereby achieving precise adjustment of the support height of the adjustable bracket 100 to a desired/horizontal precise height. The support plate 6 is then locked with respect to the screw 3 by means of the nut 7.

It can be seen that the most significant feature of the adjustable support 100 of fig. 1 and 2 is that the support height of the adjustable support 100 can be finely adjusted from above in the case of paving the road building board.

Fig. 19 shows a possible use of the adjustable support 100 shown in fig. 12, in which the screw 3 is first rotated relative to the vertical tube 2 by means of the support plate 8 of the adjustable support 100, so that an initial adjustment of the support height of the adjustable support 100 is achieved. The screw 3 is then locked with respect to the riser 2 by means of the nut 4. The support plate 8 is then fastened to the support strip 220 with screws (and/or with an adhesive). It may be desirable to secure a plurality of adjustable stands 100 at spaced locations from one another in a support strip 220. Thereafter, each adjustable support 100 is secured to a support surface, thereby distributing a plurality of support strips 220 in a predetermined distribution pattern over the support surface.

Alternatively, each adjustable support 100 may be fixed at positions distributed along each row on the supporting surface, and then the supporting height of each adjustable support 100 may be adjusted so that the supporting plates 8 of each adjustable support 100 are substantially equal to each other. A respective support strip 220 is then installed on each row of adjustable supports 100. In this way, a plurality of support strips 220 can also be distributed over the support surface in a predetermined distribution pattern.

Thereafter, a building board (without a chamfer) is laid on each support bar 220. After the whole or a certain number of building boards have been laid, the flatness between the building boards is measured and if necessary a certain support strip or strips 220 is/are finely adjusted (loosening the nuts 4 and then using the clamping plane 26 on their vertical pipes 2) to achieve a leveling of the building boards, after which the nuts 4 are tightened. With respect to fine adjustment, it should be noted that if the adjustable bracket 100 is not yet completely surrounded by the building board 200, a wrench may be inserted from the side of the adjustable bracket 100 not yet surrounded for fine adjustment; if the adjustable support 100 is already fully enclosed by the building boards 200, a building board 200 can be lifted and then a wrench can be inserted for fine adjustment. When the riser 2 is rotated, the screw 3 and the support plate 6 fixed thereto are not rotated, so that the front, rear, left, and right positions of the paved building board 200 are not affected.

Fig. 20 shows a possible use of the adjustable support 100 shown in fig. 13, in which the screw 3 is first rotated relative to the stand pipe 2 by means of the angle support plate 9 of the adjustable support 100, so that an initial adjustment of the support height of the adjustable support 100 is achieved. The screw 3 is then locked with respect to the riser 2 by means of the nut 4. The angled support plate 9 is then fastened to the support strip 220 from the bottom and one side by means of screws (and/or by means of an adhesive). It may be desirable to secure a plurality of adjustable stands 100 at spaced locations from one another in a support strip 220. Of course, it is also possible to first fix the adjustable supports 100 at positions on the supporting surface distributed along the rows, and then to mount the corresponding support strip 220 on the adjustable support 100 of each row, as described above. After the plurality of support bars 220 are distributed over the support surface in a predetermined distribution pattern, the operations of laying the building board 200 and fine-tuning are the same as or similar to those described with reference to fig. 19 and will not be described in detail.

It is understood that for the two adjustable brackets 100 shown in fig. 12 and 13, each adjustable bracket 100 may be fixed on the supporting surface, and then the supporting strip 220 may be installed on each adjustable bracket 100. Of course, this type of construction is generally only possible when the adjustable support 100 is tall, allowing the operator to install the support strip 220 from below, and requires a high degree of precision in the positioning of each adjustable support 100 on the support surface.

For the adjustable stand 100 having the structure shown in fig. 11, first, a preliminary adjustment of the support height of the adjustable stand 100 may be achieved by rotating the stand pipe 2 by the clamping portion 26 of the stand pipe 2 or rotating the screw 3 by the screwing portion 32 of the screw 3. And then paving the building board thereon. After the building board is paved, if the flatness of the building board needs to be finely adjusted, the fine adjustment can be realized by screwing the clamping part 26 or the screwing part 32 of the corresponding adjustable bracket 100. And will not be described in detail herein.

Other forms of adjustable support 100 are contemplated based on the principles of the present application.

From the above description it can be seen that the adjustable support of the present application has two height adjustment portions, one of which is associated with the riser to act on the riser and the other of which is associated with the screw to act on the screw. In this way, one of the two height adjustment portions can be used primarily for the preliminary adjustment of the support height of the adjustable support, which is carried out substantially before the laying of the building panels, and the other height adjustment portion is used primarily for the fine adjustment of the support height of the adjustable support, which is carried out substantially after the laying of all or a certain number of building panels, in order to achieve the leveling of the building panels. Adopt two altitude mixture control portions, carry out preliminary regulation and accurate adjustment to adjustable support before and after the building board of mating formation respectively, compare with the accurate adjustment before mating formation or the scheme of the accurate adjustment of limit side of mating formation limit, can simplify the construction degree of difficulty, improve the efficiency of construction.

In a preferred embodiment of the present application, the first height adjusting part is at least one pair of clamping planes formed on the outer circumference of the riser for preliminary adjustment of the supporting height, and the second height adjusting part is a male or female screw part formed on the upper end of the screw for precise adjustment of the supporting height. Such a bracket may be referred to as an up-regulation bracket since the screw portion may be screwed with a wrench from above. By adopting the upward-adjusting support, even after the plates are paved, the screw rod can still be rotated by the screwing part from the upper part, and the accurate adjustment of the supporting height is realized. This has made things convenient for the roughness of panel of mating formation to adjust widely.

In addition, according to the various adjustable supports of the present application, the supporting height can be finely adjusted by rotating the height adjusting part while the base and the top plate (plate material supporting member) at the upper end are not rotated, and the laid plate material is not displaced (even if slightly displaced) due to the fine adjustment. Particularly, for the fine adjustment of the up-regulation type bracket, the fine adjustment can be realized without taking down the plate. For the fine adjustment realized by the vertical pipe, only when the lower operation space is needed after all the plates are laid, the fine adjustment can be carried out from the lower part by lifting one plate. In contrast, in the prior art, in the support using the vertical pipe and the screw rod, the vertical pipe is fixed (e.g., riveted) to the base, the top plate is fixed to the screw rod, and the vertical pipe cannot rotate relative to the base, so that after the base is fixedly mounted, the screw rod is inevitably required to rotate the top plate, and as long as the plate is already mounted on the support, the plate on the support needs to be removed or lifted before the screw rod and the top plate are rotated.

Although the present application has been described herein with reference to particular embodiments, the scope of the present application is not intended to be limited to the details shown. Various modifications may be made to these details without departing from the underlying principles of the application.
