The utility model has the advantages of simple structure, convenient operation and strong versatility, and can be disassembled and assembled at any time, thereby improving the flexibility of the combination of the Bailey frame and widening the application surface of the Bailey frame.

Description

An I-shaped steel hoop-type device for hanging under the lower chord of a Bailey frame

technical field

The utility model relates to an I-shaped steel hoop-type device for hanging under the lower chord of a Bailey frame. the

Background technique

Currently in the period of rapid development of high-rise buildings, higher and higher buildings continue to emerge, and the application of top formwork systems is becoming more and more extensive. In the traditional top formwork system, the lower chord of the Bailey frame and the I-beam of the crane beam are connected by bolts or welding. According to the characteristics of the Bailey frame, a kind of I-shaped steel hoop type device is invented, which is easy to operate, has strong versatility, and is easy to disassemble and move at any time. the

Utility model content

The technical problem to be solved by the utility model is to provide an I-steel hoop-type device for hanging under the lower chord of the Bailey frame, which can greatly improve the construction efficiency of operators, and is safe and reliable. the

The technical problem to be solved by the utility model is achieved through the following technical solutions:

An I-shaped steel hoop-type device for hanging under the lower chord of a Bailey frame, which is characterized in that it includes a platform connector I-beam, a U-shaped hoop-type clamp, a connecting plate and high-strength bolts, and the U-shaped hoop-type clamp The bottom end is connected with the connecting plate; the U-shaped hoop clamp hugs the I-beam of the platform connector; the high-strength bolts pass through both ends of the U-shaped hoop clamp, and The upper flange plates of the I-beams of the platform connector are in contact with each other; the connecting plates are provided with T-shaped grooves, and the upper flange plates of the I-beams of the crane beam are inserted into the T-shaped grooves.

In the above solution, the width of the T-shaped groove is slightly larger than the width of the upper flange plate of the I-beam of the crane beam, and the T-shaped groove matches the upper flange plate of the I-beam of the crane beam. the

In the above solution, the I-beam of the platform connector is perpendicular to the I-beam of the crane beam. the

Compared with prior art, the beneficial effect of the utility model:

The utility model is a clamp used for hanging I-beams under the lower chord of a Bailey frame. application side of the rack.

Detailed ways

In order to better understand the utility model, the content of the utility model is further explained below in conjunction with the accompanying drawings, but the utility model is not limited to the following embodiments. the

As shown in Figure 1-3, an I-beam hoop-type device for hanging under the lower chord of a Bailey rack includes a platform connector I-beam 1, a U-shaped hoop-type clamp 2, a connecting plate 4 and high-strength bolts 5. The bottom end of the U-shaped hoop clamp 2 is connected to the connecting plate 4; the U-shaped hoop clamp 2 embraces the I-beam 1 of the platform connector; the high-strength bolt 5 passes through the U The two ends of the hoop type clamp 2, and abut against the upper flange plate of the I-beam 1 of the platform connector; the connecting plate 4 is provided with a T-shaped groove, and the upper wing of the I-beam 3 of the crane beam The edge plate is inserted into the T-groove. the

The width of the T-shaped groove is slightly larger than the width of the upper flange plate of the crane beam I-beam 3 , and the upper flange plate of the crane beam I-beam 3 can just be inserted into the T-shaped groove. the

The I-beam 1 of the platform connector is perpendicular to the I-beam 3 of the crane beam. the

During the installation process of the top formwork system, it is necessary to hang the I-beam under the lower chord of the Bailey frame to install the monorail crane, put the U-shaped hoop clamp on the I-beam of the platform connector, and then fix it with high-strength bolts, and then install the I-beam of the crane beam. The upper flange of the steel is inserted into the T-shaped groove on the lower connecting plate of the U-shaped hoop clamp, so that the connecting piece of the Bailey frame platform and the I-beam of the crane beam can be connected as a whole. the
