The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Referring to fig. 1, 2 and 3, in a first aspect, the present embodiment provides a ground overhead supporter 100, which includes a keel support 1 and a ground connector 2. The keel support 1 is used to support the keel 200, the ground connector 2 is placed on the ground and in contact with the ground, and the keel support 1 is located above the ground connector 2.

The keel support 1 includes a keel carrying portion 11 and a first connecting portion 12, and the keel carrying portion 11 is connected to an upper portion of the first connecting portion 12. The keel bearing part 11 and the first connecting part 12 can be of an integrated structure and can also be connected in a threaded manner, a welding manner and the like, and the application does not limit the structure.

The ground connection member 2 includes a ground connection portion 21 and a second connection portion 22, and the second connection portion 22 is connected to an upper portion of the ground connection portion 21. Similarly, the connection manner of the second connection portion 22 and the ground connection portion 21 can refer to the connection manner of the keel bearing portion 11 and the first connection portion 12, and the description of the application is omitted.

Wherein the first connecting portion 12 is connected with the second connecting portion 22, thereby connecting the keel support 1 with the ground connection 2.

When the ground built on stilts eyelidretractor 100 of this application was laid floor 400, place ground built on stilts eyelidretractor 100 subaerial to ground connecting portion 21 through ground connecting piece 2 is connected with ground, because ground connecting portion 21 loops through first connecting portion 12, second connecting portion 22 and is connected with fossil fragments bearing part 11, so can fix fossil fragments 200 on fossil fragments bearing part 11 of fossil fragments support piece 1, thereby realize the effect of the fixed fossil fragments 200 of ground built on stilts eyelidretractor 100. In this way, the above steps are repeated, the plurality of keels 200 are fixed by the plurality of floor overhead supporters 100, and the floor 400 is fixed to the plurality of keels 200, so that the entire floor 400 is elevated. Compared with the ground connected with the floor 400 through large-area concrete, the ground overhead supporter 100 of the present application has a smaller contact area with the floor 400 and the ground. Thus, the floor 400 is laid on the upper portion of the floor support 100, and the moisture transferred to the floor 400 from the floor through the floor support 100 is reduced, thereby improving the service life of the floor 400. Moreover, the ground supporter 100 provided by the application can be produced in batches in a factory, and can be directly installed and used when the floor 400 is laid, so that the installation site is pollution-free, the time for laying the floor 400 is shortened, and the labor cost is saved.

The first connection portion 12 and the second connection portion 22 may be connected by a stud bolt, a screw, a thread, and the like, which is not limited herein.

In order to ensure that the whole floor 400 is horizontal, it is necessary to make the plurality of keels 200 supported by the plurality of floor overhead supporters 100 be at the same horizontal level. However, the ground of some houses may be uneven, and if a plurality of ground support devices 100 with fixed height are used to be placed on the uneven ground, the keel 200 supported by the ground support devices 100 may not be on the same plane, so that the paved floor 400 is uneven. Therefore, in order to solve the above problem, the first connection portion 12 and the second connection portion 22 are screwed.

When the height of the ground overhead supporter 100 needs to be adjusted, the first connecting part 12 and the second connecting part 22 can be rotated relatively by rotating the keel supporting part 1 or the ground connecting part 2, so as to change the height position of the keel supporting part 1, thereby adjusting the total height of the ground overhead supporter 100, and enabling the keel 200 installed on one ground overhead supporter 100 to be flush with the adjacent other keels 200. Repeating the above adjusting process for a plurality of times can finally achieve the effect of making a plurality of keels 200 supported by a plurality of ground overhead supporters 100 be in the same horizontal plane.

In some embodiments, as shown in fig. 1 and 2, the first connecting portion 12 has a cylindrical structure with an external thread, the second connecting portion 22 has a cylindrical structure with an internal thread, and the first connecting portion 12 and the second connecting portion 22 are connected by the matching of the internal thread and the external thread.

In other embodiments, the first connecting portion 12 has a cylindrical structure with an internal thread, the second connecting portion 22 has a cylindrical structure with an external thread, and the first connecting portion 12 and the second connecting portion 22 are connected by the matching of the internal thread and the external thread.

Further, the ground connection portion 21 may have a disc-shaped structure, a square structure, a triangular structure, or the like.

It should be noted that, when the height of the ground overhead supporter 100 needs to be adjusted, since the keel 200 is connected to the keel supporting portion 11, and the laying direction of the keel 200 in the room is generally preset, the keel supporting portion 11 of one ground overhead supporter 100 is rotated to be limited by the keel 200 of another adjacent ground overhead supporter 100, and therefore, the ground connecting portion 21 needs to be rotated to adjust the height of the ground overhead supporter 100. As shown in fig. 4, the ground connection portion 21 of the present application may be configured in a disc-shaped configuration. The ground connection part 21 of the disc-shaped structure is not affected by other obstacles (e.g., floor heating pipes, etc.) beside during the rotation process, so that the operation of adjusting the height of the ground overhead supporter 100 is convenient.

Further, the keel support 1 further comprises a support portion 13, the support portion 13 being located between the keel carrying portion 11 and the first connecting portion 12. The support portion 13 supports the keel carrying portion 11. The keel bearing part 11 is formed with a locking groove 111. As shown in fig. 9, the keel 200 includes a bearing portion 220 and a hook 210 connected with each other, wherein the hook 210 is engaged with the engaging groove 111, and the bearing portion 220 can bear the lining board 300 or the floor 400.

Based on the above design, the keel 200 can be snapped into the keel carrier 11 by a simple push-pull operation. Also, after the keel 200 is snapped into the keel bearing 11, the keel bearing 11 limits the keel 200 from 4 degrees of freedom. For example, as shown in fig. 4, if one keel 200 is inserted into the keel supporting portion 100 along the X-axis direction, two degrees of freedom in the Y-axis direction and two degrees of freedom in the Z-axis direction of the keel 200 are both limited, the keel 200 has only two degrees of freedom in the X-axis direction, after the lining board 300 and the floor board 400 are laid on the upper portion of the keel 200, the keel 200 needs to support the gravity of the floor board 400 and the lining board 300, and under the influence of the gravity, when the keel 200 moves in the X-axis direction, a large friction force needs to be overcome, so that the keel 200 is not easily displaced. And, the joint department of fossil fragments bearing part 11 and fossil fragments 200 is closely laminated, can receive the gravity of floor 400 and the pressure that the user trampled floor 400 for a long time at fossil fragments 200, and fossil fragments bearing part 11 still has better support to fossil fragments 200 to avoid the emergence of bad conditions such as fossil fragments 200 deformation, prolonged fossil fragments 200's life.

Illustratively, as shown in fig. 1, the keel bearing part 11 is approximately square, and the slot 111 is formed around the side surface of the keel bearing part 11, and the slot 111 is square and annular. The hooks 210 of the keel 200 may be snapped into the opposite sides of the snap groove 111 as shown in fig. 4. For example, the keel 200 may be installed on the keel bearing portion 11 along the X-axis direction, or may be installed on the keel bearing portion 11 along the Y-axis direction, which satisfies the requirement that the keel 200 is installed along multiple directions.

The locking groove 111 may be located in the middle of the keel supporting portion 11, or in the upper portion of the keel supporting portion 11. The position of the specific slot 111 can be set by referring to the length (the length direction is the Z-axis direction in fig. 4) of the hook 210 of the keel 200, so as to ensure that the keel 200 and the slot 111 are tightly attached, which is not limited in the present application.

Further, the keel carrying portion 11 may be one or a plurality of. If there are a plurality of keel bearing parts 11, the keel bearing parts 11 are distributed on the supporting part 13 in a rectangular array. Illustratively, as shown in fig. 2, the number of the keel carriers 11 may be 9, and the 9 keel carriers 11 may be distributed on the supporting portion 13 in a 3 × 3 array. The number of the keel bearing parts 11 can be 12, and 12 keel bearing parts 11 can be distributed on the supporting part 13 in a 3 x 4 array.

It should be noted that the above examples are merely for convenience of description and are not to be construed as limiting the present application. The number of keel bearing parts 11 and the array distribution mode of keel bearing parts 11 can be configured according to actual requirements, and the application is not limited to the configuration.

Based on above-mentioned design, be the rectangular array with a plurality of fossil fragments supporting part 11 and distribute on supporting part 13, an overhead ground support 100 can carry out horizontal and vertical multidirectional joint with a plurality of fossil fragments 200 to a fossil fragments 200 can also carry out the joint with a plurality of fossil fragments supporting part 11, further improves fossil fragments 200's fixed strength.

Optionally, as shown in fig. 2, the keel bearing parts 11 and the supporting parts 13 both adopt a square structure, and 9 keel bearing parts 11 are arranged on the supporting parts 13 along a rectangular array. And, the arrangement direction of the rectangular array is the same as the extending direction of the sides of the supporting portion 13. Therefore, the gap between the adjacent keel bearing parts 11 can be small, and as many keel bearing parts 11 as possible can be arranged on the supporting parts 13 with the same area, so that the space utilization rate of the upper surface of the supporting part 13 is high, and the material consumption of the keel supporting part 1 is reduced.

After keel bearing part 11 and keel 200 joint, can further fix keel bearing part 11 and keel 200 through first fastener, further improve keel 200 and keel bearing part 11's joint strength. Wherein the first fastener may be a self-tapping screw, a rivet, or the like.

Therefore, the load bearing part 220 of the present application is formed with the groove 221, and the depth of the groove 221 is greater than the height of the head of the tapping screw. The head of the self-tapping screw can be accommodated in the groove 221, and the top of the head of the self-tapping screw cannot exceed the groove 221, so that the lining plate 300 cannot interfere with the head of the self-tapping screw, and the flatness of the subsequently laid lining plate 300 is ensured.

Based on the above, one groove 221 may be provided, as shown in fig. 9, the groove 221 is opened along the longitudinal direction of the keel 200, and the tapping screw may tap into any position in the longitudinal direction of the groove 21. The grooves 221 can be formed in multiple numbers, the grooves 221 are distributed at intervals along the length direction of the keel 200, and tapping screws can tap into different grooves 21. The shape of the groove 221 may be a circle or a square, which is not limited in the present application.

Further, as shown in fig. 1 and 2, a first reinforcing rib 14 is provided at a connection portion of the supporting portion 13 and the first connecting portion 12. The shape of the first reinforcing rib 14 may be triangular or fan-shaped, which is not limited in the present application. The first reinforcing ribs 14 improve the strength of the floor support 100 and make the connection of the support portion 13 with the first connection portion 12 more stable.

Similarly, a second reinforcing rib 23 is provided at the connection point of the ground connecting portion 21 and the second connecting portion 22. Similarly, the shape of the second reinforcing rib 23 may be triangular or fan-shaped, which is not limited in the present application. The second reinforcing rib 23 improves the strength of the floor support 100 and makes the connection of the floor connecting part 21 and the second connecting part 22 more stable.
