Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The embodiment is an I-beam structural body, which is used for laying a bridge frame during road and bridge construction. As shown in fig. 1 to fig. 1, the structural body comprises a plurality of i-beams 1 longitudinally arranged side by side and a plurality of steel bars 2 for connecting the i-beams 1 in series, wherein square frames 3 are respectively arranged between the front end and the rear end of each adjacent i-beam 1 in a padding way, and the top surfaces and the bottom surfaces of the square frames 3 are respectively flush with the top surfaces and the bottom surfaces of the i-beams 1 correspondingly; the rib part of each I-beam 3 is provided with a plurality of rib penetrating holes 9, the reinforcing steel bars 2 transversely penetrate through the corresponding rib penetrating holes 9, then the two ends of each reinforcing steel bar are fastened on the I-beams 1 at the two edges by bolts 7, and a gasket 8 is arranged between each bolt 7 and each I-beam 1. The structural body is arranged on a transport trolley, and the bridge girder erection machine connects the erection of the structural body and the former structural body into a whole after the structural body is conveyed to a construction position, and simultaneously forms a walking channel of the transport trolley. The structure body is an organic whole structure, and the bearing capacity is good, and travelling bogie can steady operation, greatly improves the security.
Referring to fig. 1 and 3, two sides of the upper portion of the square frame 3 are respectively attached to the side edges of the upper flange of the i-beam 1. Because the I-beam 1 is wide at the top and narrow at the bottom, a wooden wedge 4 is padded between the two sides of the lower part of the square frame 3 and the side edge of the lower flange of the I-beam 1, and the square frame 3 and the I-beam 1 are tightly contacted to form a whole under the fastening of the steel bars 2.
