Description

Fixing structure of scaffold board

Technical Field

The utility model relates to an engineering construction field especially relates to a fixed knot of scaffold board constructs.

Background

In order to meet the requirements of construction operation, a fastener-type steel pipe scaffold (collectively referred to as a scaffold) is commonly used in engineering construction. The scaffold has the main function of being used together with the scaffold board, thereby providing a temporary operation platform and playing a certain enclosing role. In the construction, the scaffold board is mostly fixed by galvanized steel wires, the galvanized steel wires are very easy to be detached for other use, and the galvanized steel wires are difficult to recycle after being used once, so that the material waste is caused. If the springboard is not fixed and walks on the springboard, the springboard is easy to shake, which is very dangerous for the operator holding heavy objects.

SUMMERY OF THE UTILITY MODEL

For overcoming the prior art defect, the utility model aims at providing a fixed knot of scaffold frame scaffold board constructs is provided with the lock hoop that can adjust length in a flexible way to but rotation angle can fix scaffold board locking on the crossbeam of scaffold frame both sides, also can fix on erecting the roof beam, adjusts in a flexible way, and locking is firm, simple to operate.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

The utility model provides a fixed knot of scaffold frame scaffold board constructs, includes scaffold board, lock hoop, connecting rod the bilateral symmetry of scaffold board sets up a plurality of connecting rods, the connecting rod has the internal thread, the lock hoop passes through the threaded rod and is connected with the connecting rod and lock through the nut.

The lock hoop comprises a hoop, a top plate, a spring, a telescopic rod, a threaded rod and a lock catch, wherein the two semicircular hoops are oppositely buckled, one end of the hoop is connected with the other end of the hoop through the shaft, the telescopic rod penetrates through the hoop, the top plate is fixed at one end, stretching into the hoop, of the telescopic rod, the spring is sleeved on the telescopic rod, one end of the spring abuts against the top plate, the other end of the spring abuts against the hoop, and the telescopic rod is fixedly connected with the threaded rod at one end, outside the hoop, of the hoop.

The hasp includes locking closure, lock axle, locking strip, and locking closure and locking strip are fixed at the both ends of lock axle, and the lock axle sets up in the round hole of a staple bolt tip, is equipped with the slot hole with locking strip looks adaptation at the tip of another staple bolt.

The threaded rod is linear or bent into a Z shape.

compared with the prior art, the beneficial effects of the utility model are that:

the utility model relates to a fixed knot of scaffold frame scaffold board constructs is provided with the lock hoop that can adjust length in a flexible way to but rotation angle can fix scaffold board locking on the crossbeam of scaffold frame both sides, also can fix on erecting the roof beam, adjusts in a flexible way, and locking is firm, simple to operate.

In the figure: 1-scaffold board, 2-lock hoop, 3-connecting rod, 4-lock hoop, 5-top plate, 6-spring, 7-lock catch, 8-telescopic rod, 9-threaded rod, 10-long hole, 11-locking bar and 12-nut.

Detailed Description

The following further describes the embodiments of the present invention:

Referring to fig. 1-4, a scaffold board fixing structure comprises a scaffold board 1, locking hoops 2 and connecting rods 3, wherein a plurality of connecting rods 3 are symmetrically arranged on two sides of the scaffold board 1, the connecting rods 3 are provided with internal threads, and the locking hoops 2 are connected with the connecting rods 3 through threaded rods 9 and locked through nuts 12.

The lock hoop 2 comprises a hoop 4, a top plate 5, a spring 6, a telescopic rod 8, a threaded rod 9 and a lock catch 7, two semicircular hoops are buckled with each other in a 4-to-4 mode, one end of each hoop is connected with the corresponding shaft, the other end of each hoop is connected with the corresponding lock catch 7, the telescopic rod 8 penetrates through the corresponding hoop 4, the top plate 5 is fixed to one end, stretching into the corresponding hoop 4, of the telescopic rod 8, the spring 6 is sleeved on the telescopic rod 8, one end of the spring 6 abuts against the top plate 5, the other end of the spring abuts against the corresponding hoop 4, and the telescopic rod 8 is fixedly connected with the threaded rod.

the lock catch 7 comprises a lock cover, a lock shaft and a lock bar, the lock cover and the lock bar are fixed at two ends of the lock shaft, the lock shaft is arranged in a round hole at the end part of one hoop 4, and a long hole 10 matched with the lock bar 11 is arranged at the end part of the other hoop 4.

the threaded rod 9 is linear or bent into a Z shape.

The utility model discloses a staple bolt 4 can 8 rotations of telescopic link relatively for connect the scaffold frame (for example crossbeam or perpendicular roof beam) that fixed equidirectional setting set up. The inside of the lock hoop 2 is provided with a telescopic rod 8 and a top plate 5 which are sleeved with springs 6 and used for tightly holding and locking connecting positions with different diameters. Connecting rod 3 is fixed on scaffold board 1, and connecting rod 3 and threaded rod 9 can adjust length, are applicable to different installation distance. When the fixing position is consistent with the height of the scaffold board 1, the lock hoop 2 with the linear threaded rod shown in the figure 2 is used for fixing on a cross beam of the scaffold which is consistent with the height of the scaffold board. When the fixing position does not coincide with the height of the scaffold board, the locking band 2 with the Z-shaped threaded rod shown in fig. 3, such as a vertical beam on a scaffold, can be used. Referring to fig. 4, the lock catch 7 is disposed on one hoop 4 and can rotate relative to the hoop 4, after the two hoops 4 are fastened, the lock strip 11 passes through the long hole of the other hoop, and the lock cover is screwed, so that the lock catch 7 rotates 90 degrees, and the two hoops 4 are fixed through the lock strip 11.
