Abstract

The utility model relates to the field of constructional engineering and aims at providing a scaffold butt-joint piece. The butt-joint piece comprises a body, wherein extending-in ends are arranged at the upper end and the lower end of the body, the outer diameters of the extending-in ends are less than the diameter of the body, and the extending-in ends can be inserted into inner cavities of steel pipes to be subjected to butt-joint, so that accurate centering of butt-joint is guaranteed. The scaffold butt-joint piece is simple in structure and convenient to use and can greatly shorten time for building scaffolds; and the scaffold butt-joint piece also can be processed and formed by skiving two ends of a short and scrapped common steel pipe, so that the butt-joint piece has the advantage of being low in cost.

Description

The scaffold interfacing part

Technical field

The utility model relates to a kind of scaffold interfacing part.

Background technology

Along with the speed-raising of engineering construction, particularly the infrastructure project such as urban viaduct, building construction is increasing in recent years, is used at large as the part-steel pipe scaffold of constructing in the process of construction of infrastructure.What generally adopt in the building of steel pipe scaffold is the method for pipe fastener, namely takes up and down a fastener that can overlap being fixedly linked as the two during the steel pipe docking; It is loaded down with trivial details to adopt this fastener not only to operate, and allows easily up and down like clockwork centering of steel pipe, thereby so that the steel tube poles on the scaffold shows as eccentric the connection, only transmits load and internal force by skid resistance; When steel pipe scaffold is taken higher and higher, the existence of this eccentric phenomena greatly reduces the resistance to overturning of bearing capacity and the scaffold of steel tube poles, thereby increases the danger of construction.

Summary of the invention

The purpose of this utility model is to overcome deficiency of the prior art, and a kind of centering is the scaffold interfacing part accurately, and cost is low, and is simple and practical.

For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of scaffold interfacing part comprises body, has the inserting end less than the external diameter of body at the up and down two ends of body, can insert in the inner chamber that needs the docking steel pipe.

As further improvement of the utility model, described inserting end is circumference, and has the external diameter identical with pipe diameter to be docked, and can closely cooperate with this steel pipe.

As further improvement of the utility model, the port of described inserting end has chamfering, and the chamfering value is conveniently carried out plug-in mounting at 1:4-10.

As further improvement of the utility model, described inserting end is coniform, and its bottom external diameter is identical with the internal diameter of steel pipe to be docked; Steel pipe is convenient to insert in the tip of circular cone, and the steel pipe that closely cooperates is convenient in the bottom of circular cone.

As further improvement of the utility model, described inserting end is the square or triangle identical with the internal diameter of steel pipe to be docked; Thereby since circle have easily error to cause cooperating can not be smooth, Comparatively speaking square or leg-of-mutton structure is more conducive to the plug-in mounting of inserting end.

As further improvement of the utility model, the length of described inserting end is 2cm.

As further improvement of the utility model, the cross section of described body is circular, and is identical with common steel tube.

As further improvement of the utility model, the outer shape of described body is square or hexagon, is convenient to clamp or stack.

Scaffold interfacing part of the present utility model, be inserted in respectively by the up and down two ends of body in the steel pipe inner chamber of required docking, realize that the accurate centering of steel pipe connects up and down, thereby eliminate the eccentric defect that conventional fastener ease of connection produces, can greatly improve the resistance to overturning of bearing capacity and the enhancing scaffold of steel pipe scaffold, and the utility model scaffold interfacing part is simple in structure, and is easy to use, can greatly shorten the time of setting up scaffold.Scaffold interfacing part of the present utility model can also be processed to form with the short common steel tube skiving two ends of scrapping, thereby has advantage with low cost.

Fig. 3 is the mounting structure sectional view of specific embodiment of the utility model 1.

Fig. 4 is the top view of Fig. 3.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Specific embodiment 1 as shown in Figure 1, this scaffold interfacing part can adopt common two ends of A3 steel pipe skiving to make, therefore this scaffold interfacing part has the body 1 of annular, have two inserting ends 2 less than the external diameter of body 1 at the up and down two ends of body 1, be socketed so that insert in the inner chamber that needs docking steel pipe 3; The structure of socket as shown in Figure 3 and Figure 4, inserting end 2 is for having the external diameter circumference identical with steel pipe 3 internal diameters to be docked, closely cooperate because drawing to have produced with steel pipe 3, thereby the stability of assurance steel tube poles structure.The length of inserting end 2 is 2cm, and its port position generally needs chamfer machining, and the chamfering value is generally at 1:4-10, is socketed in the easy like this inner chamber that enters steel pipe 3.

The distortion of the another kind of specific embodiment 1 is the cancellation chamfering, directly inserting end 2 is become coniformly, just makes its bottom external diameter identical with the internal diameter of steel pipe 3 to be docked.

Fig. 2 is the utility model specific embodiment 2, and its inserting end 2 becomes identical square of internal diameter with steel pipe 3 to be docked, also can be triangle; Because in a single day circular inserting end 2 produces deviation and assembling occurs easily do not conform to, therefore Comparatively speaking square or leg-of-mutton shape is easier cooperates in socket; Square as among Fig. 2 can be made in the outside of body 1, also can be the hexagon identical with bolt, and this shape is convenient on the one hand store and is stacked, and also is convenient on the other hand the rotation adjustment that sometimes needs in installation.

At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above examples of implementation, and many extensionals can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
