Description

Novel bolt type scaffold fastener

Technical Field

The utility model relates to a construction scaffolding technical field especially relates to a novel bolt formula scaffold fastener.

Background

Scaffold fastener that present job site used is mostly the bolt formula, and bolt formula scaffold fastener is because pretightning force ration, under mechanical vibration and nature are not hard up, the fastener glides easily. The quality of the connection of the fastener joint is significantly affected by the quality of the fastener itself and the operation of the worker. The bolt and nut have fine threads, and the rotation along the threads is blocked due to mortar falling and corrosion, so that the fastener is difficult to mount and is only destructively removed after being disassembled. In addition, in the processes of disassembly, assembly and storage, the bolts and the nuts are easy to lose, so that the maintenance cost is increased. The bolt and the nut need to be cleaned by kerosene before being used every time, and the thread is changed again to pass through the nut, so that the working hour and the cost are increased. Technical shortcoming to the existence of above-mentioned current bolt formula scaffold fastener, the utility model provides a novel bolt formula scaffold fastener here.

the utility model provides a novel bolt formula scaffold fastener, includes first semi-ring and the second semi-ring that mutual symmetry set up, the one end of first semi-ring and second semi-ring is through the articulated installation of pivot, the one end that the pivot was kept away from to first semi-ring and second semi-ring all is equipped with the horizontal segment, and two horizontal segments insert jointly and be equipped with the bolt, the top of bolt is equipped with the stopper, the bolt is close to the position department of bottom and transversely inserts and be equipped with the wedge.

Furthermore, the wedge is long-strip-shaped, and a square hole matched with the wedge is formed in the bottom of the plug pin.

Further, one side of the wedge is provided with a protrusion.

Further, the protrusion is hemispherical.

Compared with the prior art, the beneficial effects of the utility model reside in that:

1. the utility model discloses a bolt formula scaffold frame fastener replaces original bolt and nut by the bolt, has reduced bolt and nut loss, bolt and nut and has lost produced expense.

2. The utility model discloses an installation easy operation has reduced the required time of construction bolt nut, avoids frequently dismantling bolt nut, and it is fast to dismantle, and is safe in utilization, can long-time used repeatedly.

3. The utility model discloses production is convenient, and the structure of bolt is compared in bolt and nut simpler, and technical requirement is lower, can improve production efficiency greatly.

In summary, compared with the bolt type scaffold fastener, the bolt type scaffold fastener of the utility model has wider application range and simple operation, and can avoid frequently disassembling the bolt and the nut; the use is safe, and the disassembly speed is high; sturdy and durable, can long-time used repeatedly practices thrift construction cost, and in addition, utility model's bolt formula scaffold frame fastener can increase the pretightning force, avoids the not hard up scheduling problem of fastener.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-6, a novel bolt formula scaffold fastener, including first semi-ring 1 and the second semi-ring 2 that mutual symmetry set up, the one end of first semi-ring 1 and second semi-ring 2 is articulated through pivot 3 and is installed, and the one end that pivot 3 was kept away from to first semi-ring 1 and second semi-ring 2 all is equipped with the horizontal segment, and two horizontal segments are inserted jointly and are equipped with bolt 4, and the top of bolt 4 is equipped with the stopper, and bolt 4 transversely inserts near the position department of bottom and is equipped with wedge 5.

The wedge 5 is a long strip, and the bottom of the bolt 4 is provided with a square hole matched with the wedge 5. One side of the wedge 5 is provided with a protrusion 6. The protrusion 6 has a hemispherical shape.

The utility model discloses a theory of operation and use flow:

the first half ring 1 and the second half ring 2 are rotatably connected together through a rotating shaft 3 to form a fastener body. After the fastener sleeve is sleeved on a scaffold steel pipe needing to be fixed, jacks are formed in the first half ring 1 and the second half ring 2 in advance, and the bolt 4 is inserted into the jacks to be fixed and adjusted. After the adjustment is completed, the wedge 5 is placed into a square hole reserved in the bolt 4, then the wedge 5 is knocked, the protrusion 6 on the surface of the wedge 5 also enters the square hole, the bolt 4 can generate certain displacement (about 1mm) at the moment, the top surface of the wedge 5 extrudes one of the half rings (as shown in fig. 1, the top surface of the wedge 5 extrudes the lower surface of the second half ring 2), and the fastener can generate pretightening force at the moment, so that the fixing effect is achieved.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
