Detailed Description

Referring to fig. 1 and 2, the present utility model provides a high strength roof returning support movable support for being mounted on the top of a scaffold riser 2, and for supporting the roof returning at the bottom of a concrete floor 3 having a vertical member 4 above.

In a first embodiment, the movable bracket 1 provided by the utility model comprises a supporting plate 5, an upper bracket 6, a lower bracket 7, a baffle plate 8, a movable sleeve 9 and a rib plate 10.

The supporting plate 5 is rectangular and plate-shaped, and can directly support the concrete floor slab 3 in a back-jacking mode, and can also support the concrete floor slab 3 in a back-jacking mode through a batten. The lower part of the supporting plate 5 is fixedly connected with an upper supporting pipe 6, the upper supporting pipe 6 is vertically arranged, and external threads are arranged outside the upper supporting pipe 6.

The lower support pipe 7 is vertically arranged, an internal thread is arranged in the lower support pipe 7, and the upper support pipe 6 extends into the lower support pipe 7 and is in threaded connection with the lower support pipe 7. Rotation of either the upper or lower support 6, 7 adjusts the height by which the pallet 5 extends upwardly.

The bottom of the lower supporting tube 7 is fixedly connected with a horizontally arranged partition plate 8, a movable sleeve 9 is fixedly connected to the lower side of the partition plate 8, the lower supporting tube 7 and the movable sleeve 9 are separated by the partition plate 8, and the inside is not communicated. A plurality of triangular rib plates 10 are welded between the lower support pipe 7 and the partition plate 8 for increasing the strength.

The inner diameter of the movable sleeve 9 is larger than the outer diameter of the scaffold riser 2, so that the movable sleeve 9 can be sleeved on the top of the scaffold riser 2.

When in use, the movable sleeve 9 is sleeved on the top of the scaffold vertical pipe 2, and the upper support pipe 6 or the lower support pipe 7 is rotated, so that the supporting plate 5 gradually rises up until the supporting plate is tightly propped against the bottom surface of the concrete floor slab 3, and a top returning support is provided for the concrete floor slab 3.

It should be noted that, the lead screw of traditional movable support directly stretches into in the scaffold riser 2, and the lead screw is limited by scaffold riser 2 internal diameter size, and can't set up bigger diameter size, when vertical bearing capacity surpassed lead screw self bearing range, takes place to crookedly easily, causes vertical force to be unable to transfer downwards, returns the top support and loses efficacy. The diameter of the scaffold vertical pipe 2 is similar to that of a screw rod, but a transverse pipe and an inclined pipe support are arranged in the scaffold to form a stable support system, and the screw rod is independently extended out of the vertical pipe without other external supports, so that the screw rod becomes the weakest link in the whole support system. According to the utility model, by arranging the movable sleeve 9, the diaphragm plate 8 and the lower support tube 7, the upper support tube 6 is not limited by the inner diameter size of the scaffold vertical tube 2, but can be provided with a larger diameter, so that the vertical force bearing capacity is improved, and the overall supporting strength is improved.

Referring to fig. 3, in a second embodiment of the present utility model, the pallet 5 is provided in a foldable configuration for portability, transportation and storage. Specifically, the supporting plate 5 is rectangular, and comprises a fixing plate 11 and folding plates 12, wherein the two folding plates 12 are located on two sides of the fixing plate 11, the folding plates 12 are hinged to the fixing plate 11 through hinges 13, when the two folding plates 12 are in a folding state, the two folding plates 12 are contained below the fixing plate 11, and when the two folding plates 12 are in an unfolding state, the two folding plates extend out of two sides of the fixing plate 11.

Referring to fig. 4, in a third embodiment of the present utility model, the locking pipe 14 and the ring buckle pipe 16 are further installed outside the upper supporting pipe 6.

The inner wall of the locking pipe 14 is provided with internal threads, the locking pipe 14 is connected with the upper supporting pipe 6 through threads, the outer wall of the locking pipe 14 radially and outwards extends to form a plurality of symmetrical inclined support plates 15, and the top of each inclined support plate 15 is abutted to the bottom of the supporting plate 5.

The ring buckling pipe 16 is formed by abutting two semi-rings, the two semi-rings are connected through bolts, and the plurality of ring buckling pipes 16 are sleeved outside the upper supporting pipe 6 and are located between the upper supporting pipe 6 and the lower supporting pipe 7. The upper ends and the lower ends of the adjacent ring buckling pipes 16 are mutually abutted, the upper end of the ring buckling pipe 16 positioned at the uppermost part is abutted with the locking pipe 14, and the lower end of the ring buckling pipe 16 positioned at the lowermost part is abutted with the lower supporting pipe 7.

The locking tube 14 and the collar tube 16 function to provide additional support to share the vertical force load of the transfer section. When the locking pipe 14 is screwed up to the tightest, the top of the inclined support plate 15 is abutted against the supporting plate 5, one part of the vertical force born by the supporting plate 5 is transferred to the lower supporting pipe 7 through the upper supporting pipe 6, the other part of the vertical force can be transferred to the locking pipe 14 through the inclined support plate 15, and the locking pipe 14 is transferred to the lower supporting pipe 7 downwards through the ring buckling pipe 16.

It should be noted that, the height of the supporting plate 5 extending upward is not an integer multiple of the height of the single ring fastening pipe 16 in most cases, so that after the corresponding number of ring fastening pipes 16 are installed, a gap is still formed between the lower ends of the ring fastening pipes 16 and the lower supporting pipe 7, and the supporting effect of auxiliary load transmission is not achieved. At this time, a gasket can be added between the ring buckle pipe 16 and the lower supporting pipe 7, or between the movable sleeve 9 and the scaffold vertical pipe 2, so as to realize fine adjustment.

The above description is only of the preferred embodiments of the present utility model, and is not intended to limit the utility model in any way, and some simple modifications, equivalent variations or modifications can be made by those skilled in the art using the teachings disclosed herein, which fall within the scope of the present utility model.
