Abstract
The utility model discloses a scaffold connecting fastener. A bolted connection method is adopted in existing scaffolds and assembly and disassembly are inconvenient. The scaffold connecting fastener comprises a cross-shaped body and a fixed part. A cross-shaped hole is arranged inside the cross-shaped body, and a round hole is arranged in the middle of the cross-shaped hole. The fixed part is a wedge-shaped hard board and inserted into the cross-shaped hole. The method that the fixed part is in pin joint with the cross-shaped body replaces the bolted connection method, and therefore connection is firm and assembly and disassembly are convenient.
Description
Technical field
The utility model relates to the scaffold that building is built usefulness by laying bricks or stones, especially the scaffold connection fastener.
Background technology
In the building building process, use connection fastener to set up scaffold and be absolutely necessary, at present, the connection fastener of setting up scaffold mostly uses bolt and nut fastening; This structure receives mechanical shock and glides easily, and stability is not good enough, has potential safety hazard; And when dismounting, fastener of every button needs the long period, not only wastes time and energy; And reuse is very low, and maintenance cost is also high.
Though some self-locking fasteners have also appearred now, as the applying date be on March 26th, 2006 the disclosed patent No. 200420102591.5 Chinese utility model patents just disclose so a kind of fastener, fastening without bolt and nut; And adopt removable pin to connect; Dismounting has relatively also made things convenient for a lot, but structure is comparatively complicated, and production and processing is rather time-consuming; Cost is higher, and intensity and stable aspect are also undesirable.
Summary of the invention
For addressing the above problem, the utility model provides a kind of simple and reliable for structure, good stability, scaffold connection fastener easy for installation.
The technical scheme of the utility model is following: a kind of scaffold connection fastener, comprise cross main body and fixture, and open cruciform vent in the described cross main body, the middle part is provided with a circular hole, and described fixture is a wedge shape hardboard, and fixture inserts cruciform vent.Fixture is fixed in body two ends of scaffold; The cross main body then is enclosed within on another body of scaffold; When fixture inserted main body, because fixture adopts wedge-shaped design, it is firm more that the darker then whole connection fastener that fixture is inserted connects; And fixture naturally can be slotting more dark more under action of gravity, so the connection of connection fastener is also reliable more; When needing the dismounting scaffold,, can easily unload as long as upwards beat fixture because total does not have bolt.
The middle part of described cross main body is to up and down both sides are protruding, forms a hollow cylinder.It is more firm being sleeved on the body of scaffold.
The material of described fixture is an iron and steel.
The length on the last base of described fixture is greater than the length of cruciform vent one side.Fixture can wholely not slide in the hole, guarantees to be connected firmly.
Compared with prior art, the outstanding advantage of the utility model is: cross main body and fixture adopt pin joint, and fixture is wedge-shaped design, and under action of gravity, connection fastener is solid and reliable, does not worry becoming flexible; And when dismounting is very convenient as long as can become flexible and pull down upwards beaing fixture because the utility model neither one bolt, save time, and the reduction of erection time, simultaneously simple in structure, practice thrift cost.

Fig. 2 is the elevation of cross main body.
Fig. 3 is the sectional view of cross main body.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done concrete description.
A kind of scaffold connection fastener; Comprise cross main body 1 and fixture 2; Open cruciform vent 3 in the described cross main body 1, the middle part of cruciform vent 3 is provided with a circular hole 4, and described fixture 2 is a wedge shape hardboard; Material can be selected iron and steel for use, and fixture 2 is connected the two ends of body 6 and inserts cruciform vent 3.For guaranteeing to be connected firmly, the length on the last base of described fixture 2 is greater than the length of cruciform vent 3 sides.
The middle part of described cross main body 1 convexes to form to both sides up and down and is hollow cylinder 5, and body 6 injects hollow cylinders 5, guarantees Stability Analysis of Structures.
In the present embodiment, with cross main body 1 and fixture 2 pin joints, and fixture 2 is wedge-shaped design, and under action of gravity, connection fastener is solid and reliable, does not worry becoming flexible, and overall structure does not have bolt, and is easy to loading and unloading.
