Description

Technical Field

[0001] This utility model relates to the field of floor support technology, specifically an adjustable floor support structure. Background Technology

[0002] When aluminum formwork support structures are needed to provide auxiliary support for floor slabs during construction, first move the base of the support device to the designated position, then adjust the height of the support column until the aluminum formwork top plate is pressed firmly against the floor slab.

[0003] When using support devices, the common support structures on the market are simple, mostly consisting of just two telescopic and adjustable columns. Although there are support structures at the ends of the columns, the contact area between the support structures and the concrete at the ends is not easily adjustable, resulting in poor support stability. Therefore, it is necessary to design an adjustable floor support structure to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable floor support structure to solve at least one technical problem existing in the above-mentioned background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable floor support structure, comprising:

[0007] The main support rod has a first adjusting ring installed at its lower end. A top ring is provided on the outer side of the first adjusting ring. A first docking ring is fixed on the surface of the first adjusting ring. A first docking groove is opened on the surface of the top ring. The first docking ring is located in the first docking groove. A support rod is also installed on the surface of the top ring.

[0008] The first support plate is installed on the end of the main support rod near the first adjusting ring. The first support plate has a storage cavity, and an extension plate is provided inside the storage cavity. The end of the support rod away from the top ring is connected to the extension plate.

[0009] A secondary support rod is located inside the main support rod. A drive ring is threadedly connected to the surface of the secondary support rod.

The two ends of the support rod 6 are respectively hinged to the top ring 3 and the extension plate 9. The extension plate 9 forms a telescopic structure with the first support plate 7 through the storage cavity 8, which facilitates the adaptive angle rotation of the two ends of the support rod 6 on the top ring 3 and the extension plate 9 respectively. Under the push of the support rod 6, the extension plate 9 can be telescopically adjusted within the storage cavity 8.

[0035] A secondary support rod 10 is located inside the main support rod 1. A drive ring 13 is threadedly connected to the surface of the secondary support rod 10. The drive ring 13 is rotatably mounted on the end of the main support rod 1 away from the first support plate 7. A second adjusting ring 19 is mounted on the surface of the end of the secondary support rod 10 away from the main support rod 1. A top ring 3 is also mounted on the outer side of the second adjusting ring 19. A second support plate 20 is also mounted on the end of the secondary support rod 10 near the second adjusting ring 19.

[0036] In one embodiment, a guide rod 11 is fixed to one end of the secondary support rod 10 inside the main support rod 1. A guide groove 12 is provided on the inner wall of the main support rod 1, and the guide rod 11 is located in the guide groove 12. The guide rod 11 and the guide groove 12 cooperate to restrict the secondary support rod 10 from rotating inside the main support rod 1, thereby improving the stability of the two during telescopic adjustment.

[0037] In one preferred embodiment, a second docking ring 14 is fixed to the surface of the drive ring 13, and a second docking groove 15 is provided at one end of the main support rod 1 near the drive ring 13. The second docking ring 14 is located in the second docking groove 15. The drive ring 13 is rotatably connected to the main support rod 1 through the second docking ring 14 and the second docking groove 15, and the drive ring 13 can be rotated on the main support rod 1 through the second docking ring 14 and the second docking groove 15.

[0038] In one embodiment, the surface of the drive ring 13 is provided with conical tooth blocks 16 at equal angles, and a conical gear 17 is provided on the outer side of the drive ring 13. The conical gear 17 is meshed with the drive ring 13 through the conical tooth blocks 16. A crank 18 is installed on the conical gear 17. When the crank 18 is held and the conical gear 17 is rotated, the conical gear 17 can push the drive ring 13 to rotate through the conical tooth blocks 16.

[0039] In one preferred embodiment, the second adjusting ring 19 is threadedly connected to the secondary support rod 10.

The displaced second adjusting ring 19 can push the top ring 3 to move synchronously.

[0040] In one preferred embodiment, the relevant structure on the second support plate 20 is the same as that on the first support plate 7, which is beneficial for the second support plate 20 to extend the extension plate 9 like the first support plate 7, thereby improving the stability of the support.

[0041] The working principle of this utility model is as follows: First, the main support rod 1 and the auxiliary support rod 10 are erected. Then, the first adjusting ring 2 and the second adjusting ring 19 are turned respectively. At this time, the first adjusting ring 2 and the second adjusting ring 19 are displaced on the main support rod 1 and the auxiliary support rod 10 respectively through the thread. The first adjusting ring 2 and the second adjusting ring 19 push the top ring 3 to move synchronously. The top ring 3 pushes the extension plate 9 out of the storage cavity 8 through the support rod 6. Then, the crank handle 18 is turned according to the required support height. At this time, the crank handle 18 drives the bevel gear 17 to rotate. The rotating bevel gear 17 pushes the drive ring 13 to rotate through the bevel tooth block 16. At this time, the drive ring 13 rotates on the main support rod 1 through the second docking ring 14 and the second docking groove 15. The rotating drive ring 13 pushes the auxiliary support rod 10 out of the main support rod 1 through the thread.

[0042] At this time, the secondary support rod 10 rises from the main support rod 1 through the cooperation between the guide rod 11 and the guide groove 12 until the lower end of the main support rod 1 and the upper end of the secondary support rod 10 are supported on the ground and the aluminum formwork by the first support plate 7 and the second support plate 20 respectively, so that the aluminum formwork is pressed tightly against the ceiling.
