Description

Technical Field

[0001] The utility model relates to the technical field of dry-method integral paving, in particular to an overhead ground structure of a building. Background Art

[0002] Indoor prefabricated dry floor paving with heating is usually done wet, and the basic steps are: design, leveling, drawing lines, laying cement mortar, and laying boards. The disadvantage of this method is wet paving, the working environment is poor, the cement mortar is thick, and the floor load is increased. It is only suitable for horizontal and vertical board paving, and for floors with irregular board paving requirements, the construction steps are often cumbersome, and materials are seriously wasted. In addition, the lower part of the board is wet-pasted with cement mortar, and the board surface is prone to alkali return, and the lower part of the board is prone to hollowing. The construction period is long, and it is necessary to reserve time for the cement mortar to harden after the board is laid.

[0003] At present, the Chinese patent with the existing patent application number: CN201921840157.X discloses an overhead frame structure of an assembled floor, which includes: a keel, whose side is "convex"; a connecting leveling part, which includes a bearing platform, a connecting plate, a connecting platform and an adjusting screw, the connecting platform is protruding from the bearing platform, and the connecting platform is in a "cross" shape, the adjusting screw is threadedly connected to the center of the bearing platform and the connecting platform, and the adjusting screw is located at the bottom of the bearing platform; the end of the keel is sleeved on the connecting plate and docked with the end of the connecting platform; the keel is arranged in multiple pieces, and the connecting leveling parts are arranged in multiple pieces, and the multiple connecting leveling parts connect the keels to form a closed frame structure; a base plate, which is arranged in a unit frame surrounded by the keel and the leveling connector. Although it solves the waste and process caused by paving to a certain extent, it is necessary to lay a supporting structure during use. After the support structure is installed, the overall structure cannot be adjusted. Therefore, multiple measurements are required before installation to ensure the stability and accuracy of the installation, which also takes a lot of time and effort. In addition, the existing installation mostly uses bolts to fix, which increases the difficulty of subsequent adjustments. In addition, the existing Chinese patent application number is CN202010855276.3, which discloses a dry ground overhead system. The key points of its technical solution are that it includes an elastic expansion pad, a screw, a support nut and a plate body. The elastic expansion pad is buckled at the lower end of the screw rod, and the support nut is threadedly connected to the upper end of the screw rod. The elastic expansion pad, the screw rod and the support nut are arranged through, and a screwing port for the screwdriver head to be inserted and rotated is opened at the bottom of the screw rod; a support flange is provided on the outer edge of the support nut; a rivet point is provided on the upper end of the support nut, and the rivet point is at the upper end of the support flange, and the number of rivet points is 2-6; in the plate body A circular plug hole is opened in the center, and a raised positioning strip is provided on the upper surface of the plate body. The positioning strip is used to position the ground base plate. The positioning strip is an arc-shaped strip, and the positioning strip is located on the circumference of the same circle. The upper end of the support nut is inserted into the plug hole, and the support flange supports the lower surface of the plate body. Although it can improve the convenience of installation, in actual use, since the floor cannot be perfectly adapted to the device, "interference fit" or "clearance fit" often occurs during actual use. After long-term use, noise will occur due to vibration, and the external device will become loose or fall off over time.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] The installation is cumbersome and the floor is prone to collision with the frame: Most of the existing elevated floors are laid by installing the frame first and then the floor, that is, a rectangular frame structure is first installed on the ground. This requires prior measurement and adjustment, otherwise it cannot be compatible with the floor to be installed, which results in the need for continuous debugging during the installation process. Even after multiple adjustments, "interference fit" or "clearance fit" will still occur. These problems will continue to appear after long-term use, and because the frame is connected by bolts, it is very difficult to adjust or correct. Secondly, the existing elevated floor is noisy or loose because the frame cannot perfectly fit the floor, resulting in a gap between the floor and the frame. During the user's stepping, the floor and the frame will collide, thereby generating noise. For this reason, we propose a building elevated floor structure. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies of the prior art, the utility model provides a building elevated floor structure, which solves the technical problems that the existing building elevated floor structure is complicated to install and the floor is prone to collision with other objects when in use.

[0008] (II) Technical solution

[0009] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] A building overhead ground structure, the structure comprising:

[0011] Splice board;

[0012] A support member connected to the ground, wherein the support member can support the splicing plate;

[0013] The support member includes a cylindrical support column, and a rotatable screw is connected at the center of the support column, that is, the two can rotate relative to each other, and the screw is consistent with the length of the support column, and a sliding support is sleeved on the outside of the screw, and the two are connected by a thread, so that the height of the sliding support can be adjusted by rotating the screw (lifting structure), and a base is installed at the bottom of the support column, which is connected to the ground through the base to provide sufficient supporting force for the support column;

[0014] Four spherical ball heads are installed on the sliding support, and docking pieces that can be plugged into the ball heads are installed at the corners of the splicing plate.

[0015] Preferably, the sliding support comprises four groups of sliding blocks arranged in a circle, and the four groups of sliding blocks are connected by threaded rings, and the threaded rings are connected to the outside of the screw rod by threads, and when the screw rod rotates, the sliding blocks can be driven to move up and down;

[0016] Wherein, a sliding groove extending along the length direction of the support column is opened on the surface of the support column, and the sliding block is located in the sliding groove.

[0017] Preferably, the sliding support includes four groups of sliding blocks arranged in a circle, and the four groups of sliding blocks surround the outside of the screw. The inner wall of the sliding block can be directly threadedly connected to the outer wall of the screw, so when the screw is rotated, different sliding blocks can be driven to perform lifting movements respectively. On this basis, since the sliding block can be taken out from the slide groove, the height of two adjacent sliding blocks can be adjusted by adjusting the time when the four sliding blocks are inserted into the slide groove, that is, after one of the sliding blocks is inserted, the screw is rotated so that the sliding block drops a certain distance, and then the next sliding block is installed, thereby adjusting the distance between the two adjacent sliding blocks.

[0018] Preferably, an arc-shaped limiting piece is respectively provided on both sides of the sliding block, and the two limiting pieces are respectively located on the inner and outer sides of the supporting column and fit together to limit the movable range of the sliding block.

[0019] Preferably, the ball head is connected to the connecting rod at the top of the sliding block, and the connecting rod is connected to the top of the sliding block through a thread. Connecting rods of different lengths can be replaced as needed. In this way, when the ball head is plugged into the docking piece, it can be ensured that the bottom of the splicing plate is always not in contact with the top of the sliding block, avoiding collision noise.

[0020] Preferably, a plurality of elastic arc sheets are installed inside the docking piece, and the plurality of elastic arc sheets are arranged in a circle to form a hemispherical "cover". In this way, when the ball head is plugged into the docking piece, the fit between the ball head and the inner wall of the elastic arc sheet can be ensured, thereby stably grasping the ball head and ensuring the stability of the connection between the docking piece and the ball head.

[0021] Preferably, the docking piece includes a sleeve, and a limiting ring which is also annular is connected to the inner wall of the sleeve. The limiting ring is located between the sleeve and the elastic arc piece, so that when the ball head and the docking piece are plugged in, the gap between the sleeve and the elastic arc piece can be occupied, thereby locking the position between the ball head and the docking piece to avoid separation between the two. When the ball head and the docking piece are plugged in, the distance between the sleeve and the elastic arc piece is consistent with the thickness of the limiting ring.

[0022] Preferably, the structure further comprises a plug provided at the intersection of the splicing plates, wherein the plug is cylindrical and can be inserted into the groove at the top of the screw.

[0023] (III) Beneficial effects

[0024] 1. Since the splicing plate and the support are connected together by plugging, and the support and the splicing plate are fixed in a "point-to-face" manner, and the floor is raised, so that the floor can only contact with the ball head and cannot contact with other components of the support. Therefore, the technical problems of the existing building overhead floor structure being cumbersome to install and easy to collide with other objects during use are effectively solved. The floor is quickly installed while being raised to prevent it from colliding with other objects, thereby ensuring the stability of the floor and preventing noise, thereby improving the use effect of the overhead floor.

[0025] 2. Since the sliding blocks are arranged in a circular row, the screw at the center is exposed, and the sliding block can be driven to move up and down by rotating the screw, thereby realizing the adjustment of the floor installation, thereby ensuring the convenience of adjustment, and can also be freely adjusted in subsequent use as needed, thereby improving the convenience of adjustment. Secondly, a plug is inserted at the top of the screw, and the plug is clamped by the floor, so that the screw cannot rotate after installation, thereby ensuring stability after adjustment.

[0026] 3. Since a threaded sliding block is used in conjunction with a screw rod, and the sliding block is plugged into the outer wall of the support column, it is convenient for him to adjust the height between each sliding block, so that the floor above it forms a "staircase" or "inclination", thereby improving the applicability of the device.

[0043] The embodiment of the present application provides a building elevated floor structure, which effectively solves the technical problems of the existing building elevated floor structure being cumbersome to install and the floor being easy to collide with other objects when in use. When the existing building elevated floor structure is used, the splicing plate and the support are connected together by plugging, and the support and the splicing plate are fixed in a "point-to-face" manner, and the floor is erected, so that the floor can only contact with the ball head but cannot contact with other components of the support, thereby achieving rapid installation of the floor and suspending the floor so that it cannot collide with other objects, thereby ensuring the stability of the floor and preventing noise, thereby improving the use effect of the elevated floor; since the sliding blocks are arranged in a circular row, the screw at the center is exposed, and the sliding block can be driven to move up and down by rotating the screw, thereby achieving the adjustment of the floor installation, thereby ensuring the convenience of adjustment, and can also be freely adjusted in subsequent use according to needs, thereby improving the convenience of adjustment, secondly, a plug is inserted at the top of the screw, and the plug is clamped by the floor, so that the screw cannot rotate after installation, thereby ensuring the stability after adjustment. Example

[0044] The technical solution in the embodiment of the present application effectively solves the technical problems that the existing building overhead ground structure is cumbersome to install and the floor is prone to collision with other objects when in use. The overall idea is as follows:

[0045] In view of the problems existing in the prior art, the utility model provides a building overhead ground structure, a rectangular splicing plate 1, for subsequent use, a circular notch is opened on the edge of the splicing plate 1 (in order to reserve a gap for the plug 3), and different structural parts can be freely installed on the splicing plate 1 according to needs, which is not limited here, and the focus of this application is:

[0046] Support member 2 (capable of supporting the splicing plate 1 and connected to the ground): comprises a cylindrical support column 21, and a rotatable screw rod 22 is connected to the center of the support column 21, that is, the two can rotate relative to each other, and the screw rod 22 is the same length as the support column 21, such as Figure 4 As shown, a sliding support 23 is provided on the outer sleeve of the screw rod 22, and the two are connected by a thread, so that the height of the sliding support 23 can be adjusted by rotating the screw rod 22 (lifting structure), and a base 24 is installed at the bottom of the support column 21, which is connected to the ground through the base 24 to provide sufficient supporting force for the support column 21.

[0047] In order to be able to erect the floor, we install four spherical ball heads 235 on the sliding support 23, and the corners of the splicing plate 1 are installed with docking pieces 4 that can be plugged into the ball heads 235. Figure 8 and Fig. 9 As shown, a plurality of elastic arc pieces 42 are installed inside the docking member 4, and the plurality of elastic arc pieces 42 are arranged in a circular row to form a hemispherical "cover", so that when the ball head 235 is plugged into the docking member 4, the fit between the ball head 235 and the inner wall of the elastic arc piece 42 is ensured, thereby stably grasping the ball head 235. Figure 8 As shown, the stability of the connection between the docking piece 4 and the ball head 235 is ensured. Based on this, the ball head 235 is connected to the connecting rod 234 at the top of the sliding block 231, and the connecting rod 234 is connected to the top of the sliding block 231 through a thread. The connecting rod 234 of different lengths can be replaced as needed, so that when the ball head 235 is plugged into the docking piece 4, it can be ensured that the bottom of the splicing plate 1 is always not in contact with the top of the sliding block 231, avoiding collision noise.

[0048] During installation, the butt joint 4 at the bottom of the splicing plate 1 is aligned with the ball head 235 at the top of the support column 21, and then the splicing plate 1 is pressed to separate the elastic arc pieces 42 inside the butt joint 4. At this time, the ball head 235 can enter the space surrounded by the elastic arc pieces 42. Figure 8As shown, the connection between the splicing plate 1 and the support column 21 is completed in this way. The whole process is simple and convenient, and the disassembly is also simple, and only the two need to be separated.

[0049] In order to prevent the elastic arc piece 42 from separating from the ball head 235 after installation, a similarly annular limiting ring 43 is connected to the inner wall of the sleeve 41. The limiting ring 43 is located between the sleeve 41 and the elastic arc piece 42. In this way, when the ball head 235 is plugged into the docking piece 4, the limiting ring 43 occupies the gap between the sleeve 41 and the elastic arc piece 42, thereby locking the position between the ball head 235 and the docking piece 4 to prevent the two from separating from each other.

[0050] Lifting structure: The sliding support 23 is composed of four sliding blocks 231 arranged in a circle, and the four sliding blocks 231 are all connected to the same threaded ring 232. The threaded ring 232 is threadedly connected to the outside of the screw rod 22, so when the screw rod 22 rotates, it can drive the sliding blocks 231 to move up and down, thereby realizing the lifting and lowering of the entire structure. In order to prevent the screw rod 22 from rotating after adjustment, a plug 3 is set at the intersection of the splicing plate 1. The main body of the plug 3 is cylindrical (the bottom is in the shape of a hexagonal wrench) and has four branches, which can be inserted into the gap between two adjacent splicing plates 1, such as Figure 1 As shown, the bottom of the plug 3 can be inserted into the groove (hexagonal groove) at the top of the screw 22, so that the rotation of the screw 22 can be limited by the limit of the splicing plate 1, thereby completing the locking of the screw 22, and when adjustment is needed later, the plug 3 can be removed as needed, and the hexagonal wrench can be inserted into the groove at the top of the screw 22 to adjust it, such as Figure 6 shown.

[0051] The surface of the support column 21 is provided with a sliding groove in the same direction as its length. Figure 2 and Figure 3 As shown, the sliding block 231 is located in the slide groove, so that the sliding block 231 can move up and down along the slide groove. In order to ensure the stability of the movement of the sliding block 231, an arc-shaped limiting piece 233 is provided on both sides of the sliding block 231. Figure 5 As shown, the two limiting pieces 233 are respectively located on the inner and outer sides of the support column 21 and fit together, so that the range of motion of the sliding block 231 can be limited, just like a clip. Figure 7 shown.

[0052] In the specific implementation process, the splicing plate 1 (including a structural plate 11 and a frame 12 supporting the structural plate 11) is installed: the docking piece 4 at the bottom of the splicing plate 1 is made to correspond to the ball head 235 at the top of the support column 21, and then the splicing plate 1 is pressed to separate the elastic arc pieces 42 inside the docking piece 4. At this time, the ball head 235 can enter the space surrounded by the elastic arc pieces 42, such as Figure 8As shown, the connection between the splicing plate 1 and the support column 21 is completed in this way. The whole process is simple and convenient, and the disassembly is also simple, and only the two need to be separated.

[0053] To adjust the height, insert a hexagonal wrench into the groove at the top of the screw rod 22 and then rotate the hexagonal wrench to drive the screw rod 22. Figure 6 As shown, the four sliding blocks 231 are all connected to the same threaded ring 232, and the threaded ring 232 is threadedly connected to the outside of the screw rod 22, so when the screw rod 22 rotates, it can drive the sliding blocks 231 to move up and down, thereby realizing the lifting and lowering of the entire structure. In order to prevent the screw rod 22 from rotating after adjustment, a plug 3 is set at the intersection of the splicing plates 1. The main body of the plug 3 is cylindrical (the bottom is in the shape of a hexagonal wrench) and has four branches, which can be inserted into the gap between two adjacent splicing plates 1, as shown in FIG. Figure 1 As shown, the bottom of the plug 3 can be inserted into the groove (hexagonal groove) at the top of the screw 22, so that the rotation of the screw 22 can be limited by the limit of the splicing plate 1, thereby completing the locking of the screw 22, and when adjustment is needed later, the plug 3 can be removed as needed, and the hexagonal wrench can be inserted into the groove at the top of the screw 22 to adjust it, such as Figure 6 shown. Example

[0054] Based on Example 1, the embodiment of the present application is to adjust the height difference between two adjacent splicing plate assemblies as needed. The overall idea is as follows:

[0055] like Fig.10 As shown, the sliding support 23 includes four groups of sliding blocks 231 arranged in a circle, and the four groups of sliding blocks 231 surround the outside of the screw rod 22. The inner wall of the sliding block 231 can be directly threadedly connected to the outer wall of the screw rod 22, so when the screw rod 22 is rotated, different sliding blocks 231 can be driven to perform lifting movements respectively. On this basis, since the sliding block 231 can be taken out from the slide groove, the height of two adjacent sliding blocks 231 can be adjusted by adjusting the time when the four sliding blocks 231 are inserted into the slide groove, that is, after one of the sliding blocks 231 is inserted, the screw rod 22 is rotated so that the sliding block 231 drops a certain distance, and then the next sliding block 231 is installed, thereby adjusting the distance between the two adjacent sliding blocks 231.

[0056] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
