And the four cross beams of the square frame fixing frame are welded and fixed.
The four beams of the square frame are connected through square bolts, a row of through holes are formed in the end parts of the front beam and the rear beam, a row of through holes are formed in the end parts of the left beam and the right beam, and square bolts penetrate through the two through holes.
Compared with the prior art, the frame fixing frame has the technical effects that the frame fixing frame is prefabricated, is fixed through bolts, and is more convenient and faster to operate compared with field welding.

FIG. 2 is a schematic diagram of the present utility model in use.
Fig. 3 is an enlarged schematic view of the front cross member.
Detailed Description
The utility model will be described in detail below with reference to the drawings and detailed description thereof.
1-2, A steel trestle bailey beam assembled connection structure comprises a square frame fixing frame, wherein the square frame fixing frame is of a bilateral symmetry structure and comprises a front beam 11, a left beam 13, a rear beam 12 and a right beam 14 which are sequentially connected, the front beam 11 and the rear beam 12 are connected with a lower pressing plate 20 through pressing bolts A21, the lower pressing plate 20 extends to the inner side of the square frame fixing frame and is used for pressing the upper edge of a bailey beam 92, the left beam 13 and the right beam 14 are connected with an upper pressing plate 30 through pressing bolts B31, the upper pressing plate 30 extends to the inner side of the square frame fixing frame and is used for pressing the lower edge of a distribution beam 91 (I-steel).
The front cross member 11, the left cross member 13, the rear cross member 12, and the right cross member 14 are collectively referred to as four cross members.
The four cross beams of the square frame fixing frame can be welded and fixed, and at this time, in order to adapt to the widths of the beret beams 92 and the distribution beams 91, the lengths of the lower pressing plate 20 and the upper pressing plate 30 can be adjusted.
But if the lengths of the lower and upper platens 20, 30 are too long, the compression may be loose due to their own deflection.
For this purpose, as shown in fig. 3, four beams of the square frame are connected by square bolts 15, the ends of the front beam 11 and the rear beam 12 are respectively provided with a row of through holes 111, the ends of the left beam 13 and the right beam 14 are respectively provided with a row of through holes, and the square bolts 15 penetrate through the two through holes 111. Thus, by selecting the through holes at the proper positions, the distances between the front beam 11 and the rear beam 12 and between the left beam 13 and the right beam 14 are adjusted, so that the widths of the bailey beam 92 and the distribution beam 91 can be conveniently adapted.
The working principle is as follows:
When constructing the steel trestle, lay bailey beam 92 after ending, place the square frame mount suitable position, specifically: the front beam 11 and the rear beam 12 are respectively placed outside the upper edge of the bailey beam 92, so that the lower pressure plate 20 is positioned below the upper edge of the bailey beam 92, and corresponds to the bolt holes of the front beam 11 and the rear beam 12, and when the compression bolts a21 are screwed down by nuts, the fixation of the front beam 11, the rear beam 12 and the bailey beam 92 is completed.
The distribution beam 91 is placed on the bailey beam 92, the left cross beam 13 and the right cross beam 14 are respectively placed outside the lower edge of the distribution beam 91, the upper pressing plate 30 is positioned on the upper side of the lower edge of the bailey beam 92, and corresponds to the bolt holes of the left cross beam 13 and the right cross beam 14, and when the pressing bolt B31 is screwed down by using a nut, the fixation of the left cross beam 13 and the right cross beam 14 and the distribution beam 91 is completed.
In this way, the fixation of the distribution beam 91 and the beret beam 92 is completed.
It should be noted that, for the sake of firmness, the junction of each distribution beam 91 and each beret beam 92 needs to be connected and fixed by a connecting structure according to the present application.
The utility model has the characteristics that:
S1, on-site welding is replaced by bolts, so that the installation is convenient and quick, the construction efficiency is improved, and the construction period is shortened.
S2, the additional square frame fixing frame fixed by welding is prefabricated, so that the defects of high processing difficulty and long construction period of a construction site are overcome.
S3, the square frame fixing frame can be adjusted according to the size of the distribution beam, and the proper upper pressing plate is replaced to be suitable for the distribution beams of various types.
See the prior art for further content.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
