Abstract

The utility model relates to a device for abutting steel pipe vertical rods in a steel pipe scaffold. The device comprises an upper steel pipe (1) and a lower steel pipe (2) which are needed to be abutted, and is characterized in that guide pipes (3) which are movably connected are arranged between the upper steel pipe (1) and the lower steel pipe (2), the upper ends and the lower ends of the guide pipes (3) are respectively inserted in the upper steel pipe (1) and the lower steel pipe (2) to form a cup-joint structure. Through the device, the centers of the two steel pipe vertical rods can be conveniently enabled to be in the same line, and the device can ensure that the axes are abutted, therefore, the bearing capacity and integral stability of the steel pipe scaffold can be greatly enhanced, the time for lapping the scaffold is shortened, and the device is safe and convenient.

Description

A kind of device of steel tube poles docking in steel pipe scaffold

Technical field

The utility model relates to the steel pipe scaffold that adopts in the construction work, especially relates to the device that in setting up the steel pipe scaffold process steel tube poles is docked.

Background technology

Increasing along with infrastructure projects such as urban viaduct, building constructions, most structure need to adopt steel pipe scaffold in the process of construction of infrastructure, the present construction field of method of the vertical rod docking in the steel pipe scaffold has mainly adopted the method for fastener, the docking calculation of this fastener is not only loaded down with trivial details in operation, and unavoidably have a joint unfitness of butt joint, so that steel tube poles shows as eccentric the connection, transmit load and internal force by skid resistance, therefore greatly reduce the resistance to overturning of bearing capacity and the scaffold of steel tube poles.

Summary of the invention

The purpose of this utility model is to overcome deficiency of the prior art, a kind of device of steel tube poles docking in steel pipe scaffold.

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

A kind of device of steel tube poles docking in steel pipe scaffold, comprise the upper steel pipe and the lower steel pipe that need docking, be provided with the guide pipe that is movably connected between upper steel pipe and lower steel pipe, insert respectively in steel pipe and the lower steel pipe at the up and down two ends of guide pipe, forms the socket joint type structure.

As further improvement of the utility model, the external diameter at two ends is consistent with the internal diameter of upper steel pipe and lower steel pipe respectively about the described guide pipe, and length is at 2cm-5cm.

As further improvement of the utility model, the described guide pipe up and down port position at two ends has chamfering, and the chamfering value is at 1:4-10.

As further improvement of the utility model, described guide pipe is the A3 steel, and it is circular that cross section is.

The device of steel tube poles docking of the present utility model, the guide pipe that middle employing can be socketed up and down links to each other, and the top and the bottom of guide pipe are stretched in the up and down steel tube poles of intending docking, are socket joint and fix, thereby steel pipe is fixedly connected one by one, and it is simple and practical to connect effect.Compared to existing technology, the beneficial effects of the utility model are: by this device can allow easily two steel tube poles the center be on the same line, guarantee its axle center docking, therefore can greatly improve the resistance to overturning of bearing capacity and the enhancing scaffold of steel pipe scaffold, and shorten the time of setting up scaffold, and safe ready.

Description of drawings

Fig. 1 is the structural representation in the specific embodiment of the utility model.

Fig. 2 is the top plan view of Fig. 1.

The specific embodiment

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

As shown in Figure 1, the device of the utility model steel tube poles docking in steel pipe scaffold, comprise the upper steel pipe 1 and the lower steel pipe 2 that need docking, between upper steel pipe 1 and lower steel pipe 2, a guide pipe that is movably connected 3 is arranged, insert respectively in steel pipe 1 and the lower steel pipe 2 at the up and down two ends of guide pipe 3, forms the socket joint type structure.

As shown in Figure 2, the material of guide pipe 3 is the same with steel pipe, all adopt the A3 steel, it is circular that cross section is, and it is consistent with the internal diameter of steel tube poles that upper and lower side intends stretching into steel pipe external diameter partly, and length is 2cm, wall thickness 4mm, the external diameter of mid portion is consistent with the external diameter of steel tube poles, and internal diameter is consistent with the internal diameter of top and the bottom, and length is 3cm.

The port position at guide pipe two ends about in the of 3 can have chamfering, and the chamfering value is between 1:4-10, and chamfering is convenient to when inserting up and down steel pipe more smooth.

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.
