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 open air floor structure in which an open air floor is conveniently constructed using open air floor panels (e.g., corrosion-resistant wood panels, composite panels, etc.) and the adjustable support of the present application.

The adjustable stand of the present application can provide an adjustable support height for the flooring sheets to support the flooring sheets at a consistent desired height. The adjustable support may be provided in a variety of sizes, each size having a corresponding range of adjustable support heights. Some exemplary configurations of the adjustable support of the present application are described below.

First, as shown in fig. 1 and fig. 2, a possible embodiment of the adjustable bracket 100 mainly includes: a base 1; a riser 2, the lower end of which is riveted to the base 1 and which has the ability to rotate about the 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 so that the screw 3 can be screwed into the riser 2 from the upper end of the riser 2 and the height of the screw 3 exposed 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; and a substantially flat support plate (top plate) 8 riveted to the upper end of the screw 3.

The base 1 is pressed from a metal sheet, is adapted to be mounted on the ground by means of an adhesive or a fastener, and may have various shapes such as a circular shape, a square shape, a polygonal shape, etc., which are suitably supported and arranged on the ground. The base 1 is raised in the middle and riveted with the lower end of the stand pipe 2. A plurality of mounting holes may be formed in the base 1 around the riveting portion. The mounting holes may be of different sizes for different sizes of nails/bolts/screws or the like to be connected to the ground.

The riser 2 may be machined from metal tubing (including extrusion processes). The riser 2 may comprise a plurality of diameter change locations, which may be achieved by extrusion. The lower part or other parts of the riser 2 are pressed so as to form at least one pair of circumferentially distributed clamping planes 21 located opposite each other at the outer periphery. An operator can grip the gripping surface 21 (or simply grasp the gripping surface 21 by hand) with a tool such as a wrench to rotate the riser 2 relative to the base 1.

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.

The body portion of the screw 3 is formed with an external thread and is riveted to the support plate 8 at the upper end of the body portion. The screw 3 may be hollow. The support plate 8 is a metal member. In the assembled state, the support plate 8 is perpendicular to the central axis of the adjustable support 100. Screw holes 81 may be formed in the support plate 8.

As shown in fig. 3, the upper surface of the support plate 8 is adapted to receive the support strip 10, and the support strip 10 and the support plate 8 are fastened together (and/or with an adhesive) by screws passing through the screw holes 81.

When the support strip 10 is not installed, an operator holds the vertical pipe 2 with one hand and rotates the support plate 8 with the other hand, so that the screw 3 can be driven to rotate relative to the vertical pipe 2, and the height of the support plate 8 can be adjusted. This adjustment may be referred to as a preliminary adjustment. After the support strip 10 and the support plate 8 are fastened together (even floor boards are laid on the support strip 10) and the base 1 is installed on the ground, the support strip is clamped on the clamping plane 21 of the vertical pipe 2 by using a tool such as a wrench in a state that the nut 4 is loosened, and the vertical pipe 21 is rotated, as shown in fig. 3, so that the height of the support plate 8 can be finely adjusted. During the fine adjustment, the base 1, the support plate 8 and the support strip 10 are kept against rotation. In this way, the transverse position of the laid floor panels is not affected.

Fig. 4 shows another possible embodiment of the adjustable support 100, in which an angled support plate (top plate) 9 is riveted to the upper end of the screw 3. The angled support plate 8 may be a metal piece having a transverse portion and a longitudinal portion perpendicular to each other. In the assembled state, the transverse portion is perpendicular to the central axis of the adjustable support 100. The upper surface of the transverse portion and the inner surface of the longitudinal portion are adapted to be abutted by the bottom surface and one side surface of the support strip 10, respectively. To this end, screw holes 81 may be formed in the transverse and longitudinal portions for fastening the support strip 10 to the gusset plate 8 with screws (and/or with an adhesive). Other aspects of the adjustable support 100 of fig. 4 are the same as or similar to those of fig. 1 and 2 and will not be described again here.

Fig. 5 shows another possible embodiment of an adjustable support 100, mainly comprising a base 101; a first screw 102, the lower end of which is fixed on the base 101; a support plate 8, similar to that of fig. 1, 2, or similar to that of fig. 4; a second screw 103, the upper end of which is fixed to the support plate 8; a stand pipe 104 having a lower end internal thread and an upper end internal thread, an upper side portion of the first screw 102 being screwed into the stand pipe 104 and engaged with the lower end internal thread thereof, and a lower side portion of the second screw 103 being screwed into the stand pipe 104 and engaged with the upper end internal thread thereof. The rotation directions of the external threads of the first screw 102 and the internal threads at the lower end of the stand pipe 104 are opposite to the rotation directions of the external threads of the second screw 103 and the internal threads at the upper end of the stand pipe 104. The first nut 105 and the second nut 106 are used for locking the first screw 102 and the second screw 103 to the stand pipe 104 respectively. The riser 104 is formed at its outer periphery with at least one pair of clamping planes 21 located opposite to each other. An operator can use a wrench or other tool to clamp on the clamping plane 21 (or simply grasp the clamping plane 21 with a hand) to rotate the stand pipe 104 relative to the base 101 and the support plate 8 (or the angled support plate 8), so that the support plate 8 (or the angled support plate 8) can move up and down to adjust the supporting height of the adjustable support 100. Similarly, after the support strip 10 and the support plate 8 are fastened together (even when the floor boards are laid on the support strip 10) and the base 101 is installed on the ground, the height of the support plate 8 can be finely adjusted by turning the stand pipe 104 by clamping the stand pipe 104 on the clamping plane 21 of the stand pipe 104 with the

nuts

105 and 106 loosened. During the fine adjustment, the base 101, the support plate 8 and the support strip 10 are kept against rotation. In this way, the transverse position of the laid floor panels is not affected.

Fig. 6 and 7 show another adjustable support 100 of the present application, which is different from the adjustable support 100 of fig. 1 and 2 in that a support plate 8 is not riveted to the upper end of a screw rod 3, but a support plate 6 is rotatably supported on the upper portion of the screw rod 3. Specifically, the support sleeve 5 is screwed to the screw 3 above the nut 4. The support plate 6 is 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. Further, a protruding screw portion 31, 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 screw 3. An operator can use a wrench to catch on the screw portion 31 to rotate the screw 3 relative to the riser 2. Alternatively, a recessed screw portion, such as a rectangular groove, a hexagonal groove, a straight groove, or the like, into which a tool such as a plug wrench can be inserted may be formed in the upper end of the screw rod 3. An operator can insert a plug wrench into the screw to turn the screw 3 relative to the riser 2. The support plate 6 can support floor boards thereon. After the base 1 is installed on the floor and the floor board is laid on the support plate 6, the screw 3 is rotated with respect to the support plate 6 by rotating the screw part 31 from above with a tool such as a wrench in a state where the nut 4 is tightened and the nut 7 is loosened, thereby finely adjusting the height of the support plate 6. During fine adjustment, the base 1, the support plate 6 and the floor panels supported on the support plate 6 are held against rotation. In this way, the transverse position of the laid floor panels is not affected.

As an important feature of the present application,the main components of the adjustable support 100 are made of steel 20 with a protective film 30, as shown in fig. 8. The protective film 30 can protect the steel material 20 from being rusted. The protective film 30 is a magnesium-containing zinc-based film, for example, a magnesium-containing zinc-aluminum film, such as

One of the characteristics of this protective film is that, if a certain portion (for example, a portion indicated by 40 in the drawing) of the steel material 20 is exposed due to processing, assembly, or the like, aluminum and magnesium are precipitated from the protective film 30 over a period of time (for example, several months to several years), and a fine zinc-based protective film is formed on the exposed portion, as shown in fig. 9. Thus, the entire surface of the steel material 20 can be protected from corrosion. Thereby extending the useful life of the adjustable support 100. The parts that can be made of steel 20 with protective film 30 can be the base, riser, screw, and support plate in adjustable support 100.

Next, some possible operation ways of constructing an open floor using the adjustable support 100 of the present application will be described.

As schematically shown in fig. 10, the adjustable bracket 100 shown in fig. 1 and 2, or the adjustable bracket 100 shown in fig. 4 or 5 is used. First, the supporting plate 8 of each adjustable support 100 is fastened to a supporting strip 10 by screws (and/or by means of an adhesive) and then turned over to fix the base 1 to the ground by screws (and/or by means of an adhesive). The riser 2 is turned relative to the base 1 by a wrench being stuck on the clamping plane 21 (or by gripping the clamping plane 21 by hand) in order to provide a fast and accurate levelness of the support bars 10 and a consistent levelness between the individual support bars 10. Thereby, the plurality of support bars 10 are distributed over the ground in a predetermined distribution pattern. Alternatively, each adjustable support 100 may be installed at positions distributed along each row on the ground, and then the supporting height of each adjustable support 100 is adjusted so that the supporting plates 8 of each adjustable support 100 are substantially equal to each other. Then, a respective support strip 10 is mounted on each row of adjustable supports 100. In this way, it is also possible to distribute a plurality of support strips 10 over the ground in a predetermined distribution pattern. The support strips 10 mounted on the ground are parallel to each other as shown in fig. 11.

Thereafter, as shown in fig. 12, a floor panel 200, such as a wood or composite floor panel, is laid on each support strip 10. The floor panel 200 may be an elongated panel. After a certain number (or even all) of the floor panels 200 have been laid, the flatness between the floor panels is measured and, if necessary, a fine adjustment of one or some of the adjustable supports 100 is/are carried out. Specifically, the nuts 4 (or the nuts 105 and 106) are loosened, the riser 2 is screwed by using the clamping plane 21 on the riser 2, so that the floor boards are accurately leveled, and then the nuts are screwed.

Thus, the open floor is completed. The open floor thus formed has high surface flatness.

Fig. 13 shows the way in which an open floor is constructed using the adjustable support 100 shown in fig. 6, 7. First, the adjustable supports 100 are distributed on the indoor floor in a matrix. Then, the floor panel 200 is laid on the support plate 6 of the adjustable bracket 100. In order to make the upper end of the screw 3 of the adjustable bracket 100 free, the corners of the building boards 200 are chamfered in advance, thereby creating a space 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.

In this way, the floor panel 200 is fully paved in the entire predetermined area. Thereafter, the flatness between the floor panels is measured and, if necessary, a fine adjustment of the or some adjustable support 100 is performed. Specifically, the nut 7 is loosened from above, the screw 3 is screwed from above by the screwing portion 31 of the screw 3, the floor boards are accurately leveled, and then the nut 7 is screwed. Thus, fine adjustment of the adjustable bracket 100 does not affect the lateral position of the flooring board 200 thereon.

After the fine adjustment, a filler block 202 is filled in the space between the corners of the flooring board 200 to close the space defined between the chamfered corners of the flooring board 200. In this way, the open floor of the present application is constructed.

Another possible way of operating to construct an open floor with an adjustable support 100 is schematically shown in fig. 14. In which the adjustable bracket 100 of fig. 1 and 2 (or the adjustable bracket 100 shown in fig. 4 or 5) is used to support the flooring material 200 at the boundary position of the open floor, and the adjustable bracket 100 shown in fig. 6 and 7 is used to support the flooring material 200 at other positions than the boundary. After some or all of the flooring boards 200 are laid, the surface flatness of the flooring boards 200 is measured, and if necessary, some or some of the adjustable brackets 100 are finely adjusted, thereby completing the open floor.

Another possible way of operating to construct an open floor with an adjustable support 100 is schematically shown in fig. 15. Wherein a vertical support wall 400 is constructed at the boundary position of the open air floor, and the support wall 400 has a support portion thereon for supporting the edge of the flooring board 200 at the boundary position of the open air floor. The adjustable support 100 shown in fig. 6 and 7 (or the adjustable support 100 shown in fig. 1 and 2, or the adjustable support 100 shown in fig. 4 or 5) is used to support the flooring board 200 at other positions than the boundary. After some or all of the flooring boards 200 are laid, the surface flatness of the flooring boards 200 is measured, and if necessary, some or some of the adjustable brackets 100 are finely adjusted, thereby completing the open floor.

Other types of adjustable supports can be constructed and other operational modes of constructing an open-air floor using the adjustable supports and floor panels can be devised in accordance with the basic principles and specific needs of the present application.

It can be seen that the adjustable support used in the open floor construction according to the application is made of metal. Compared with the prior art adopting a plastic support, the metal support has high strength and durability, and the service life of the support can be prolonged.

According to the preferred embodiment of the application, the main components of the adjustable bracket are made of steel with the protective film, and the protective film is a zinc film containing magnesium and has self-repairing capability, so that the main components of the adjustable bracket are reliably prevented from being rusted, and the service life of the adjustable bracket is prolonged.

Further, according to the application, the adjustable support is adopted in the open-air floor structure to support the open-air floor boards, the support height of the support can be adjusted through the adjustment of the support, before the installation of the support, after the support is installed and after some or all boards are paved, so that the flatness of the surfaces of the boards can be conveniently and quickly realized, and the construction speed is improved.

In addition, with the adjustable support of various forms of the present application, the supporting height can be finely adjusted by rotating the height adjusting part arranged on the vertical pipe or the screw rod under the condition that the base and the top plate at the upper end are not rotated, and the paved plate can not be dislocated (even if slightly dislocated) due to the fine adjustment. 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.
