[0027] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0028] See also Figure 1-6 The assembled steel pontoon provided by the present invention comprises a plurality of mutually connectable boxes 1, and the boxes 1 are surrounded by at least six box panels 2 to form a rectangular structure. Adjacent box panels 2 are fixed by bolts for easy disassembly and assembly. Among them, the box panels 2 located on the top surface of the boxes 1 are also provided with inspection holes 7 to facilitate installation and maintenance personnel to enter the boxes 1. For details, please refer to Figure 3The box panels 2 are provided with flange plates 21 on all four sides, and a plurality of transverse or longitudinal ribs are connected between the two opposing flange plates 21. In this application, the transverse ribs are made of flat steel, and the vertical ribs are made of angle steel 4. In particular, angle steel 4 is provided on the outer edges of the box body 1, and the surfaces of the two wing plates of the angle steel 4 are provided with through holes corresponding to the flange holes on the flange plates 21, so that the angle steel 4 can be fixed to the flange plates 21 by bolts, thereby realizing vertical splicing of two adjacent box panels 2 through the angle steel 4. A sealing strip is also sandwiched between the flange plates 21 and the wing plates of the angle steel 4. Please refer to Figure 2 The box body 1 is also provided with a steel inner frame 3 for connecting and supporting the box panels 2. The inner frame is generally arranged in a cross shape to resist deformation of the box panels 2. A plurality of stiffening plates 42 are also provided on the angle steels 4 located on the four sides of the top surface of the box body 1. The stiffening plates 42 are provided with lifting holes. Stiffening plates 42 with lifting holes are provided on the side of the top angle steel 4 to facilitate the lifting of the box body 1 using snap rings.

[0029] As a further improvement to the above scheme, please refer to Figure 4-6 The assembled steel pontoon provided by the present invention is also provided with at least one vertical steel pipe on the edges of both wings of the vertical angle steel 4, and the steel pipes on the left and right sides of the interface between the two boxes 1 are staggered. When the two boxes 1 are spliced ​​together, the vertical steel pipes at the staggered positions in the interface between the two boxes 1 are connected in series by inserting rods to achieve the initial splicing of the two boxes 1. It is convenient to lay I-beams 6 between the top surfaces of the two adjacent boxes 1 to achieve stable series positioning between the boxes 1, thereby enhancing the connection stability between the boxes 1. When multiple boxes are arranged in a field shape, such as Figure 1 As shown, two layers of I-beams need to be laid. If the bottom I-beam is arranged longitudinally and connected to the box, the top I-beam is arranged horizontally and connected to the bottom I-beam, thereby realizing multi-box splicing. Example

[0030] This embodiment aims to provide a method for fastening the box 1 and the I-beam 6 thereon. Figure 5The stiffening plates 42 are arranged in pairs. Each of the two stiffening plates 42 is provided with a first folding plate 45 on its opposite side, and the first folding plate 45 has a first bent portion at the end away from the stiffening plate 42. The first folding plates 45 have a first mounting hole on the side near the stiffening plate 42, facilitating the fastening of the first folding plates 45 to the stiffening plate 42 by passing a bolt through the first mounting hole and the lifting hole. Obviously, a single long bolt can be used to simultaneously lock and secure the two first folding plates 45. If the first bent portions of the two first folding plates 45 are positioned facing each other, they can be closed to form a claw. The specific application scenario and usage method of the claws are as follows: when laying the I-beam 6 between the top surfaces of two adjacent boxes 1, the first bent portions of the two first folded plates 45 are first inverted on the surfaces of the left and right wing plates at the bottom of the I-beam 6, and then a long bolt is passed through the two first folded plates 45 and the two stiffening plates 42 in sequence and then tightened to clamp the I-beam 6; one box 1 has two sets of claws that simultaneously clamp the I-beam 6, and the two assembled box 1 has four sets of claws that simultaneously clamp the I-beam 6, and multi-point clamping can achieve a stable connection between the box 1 and the I-beam 6. Example

[0031] This embodiment aims to provide a fastening method different from that of the first embodiment. Figure 7-9 Multiple clamping members 5 are also provided on the angle steels 4 located on the four sides of the top surface of the box body 1. These clamping members 5 include a bottom plate 51 connected to the angle steel 4. A second folding plate 52 is hingedly connected to each end of the bottom plate 51. The second folding plate 52 has a second bent portion at the end away from the bottom plate 51. A second mounting hole is also defined on the surface of the second folding plate 52, located between the bottom plate 51 and the second bent portion. The second mounting hole facilitates connecting the two second folding plates 52 in series with long bolts to create a clamping effect at the second bent portion.

[0032] In particular, in the second embodiment, there are two ways to connect the bottom plate 51 and the angle steel 4: one is that the bottom plate 51 is directly welded to the angle steel 4 before clamping; the other is that an adjustment hole that is compatible with the through hole of the angle steel 4 is opened on the surface of the bottom plate 51. Before clamping, the bottom plate 51 and the angle steel 4 are connected by connecting bolts 53 and connecting nuts, and the connecting nuts are not tightened so that the bottom plate 51 can be pulled upward for a certain distance. Then, after the I-beam is clamped at the second bending portion (at this time, the long bolts connecting the two second folding plates 52 are loosely tightened instead of being completely tightened), the connecting nuts are tightened. The connecting bolts 53 and the connecting nuts are used in combination to apply a downward pulling force to the clamping component 5 to strengthen the clamping force. After the vertical connecting nuts are tightened, the horizontal long bolts are tightened completely. Among them, the connecting bolt 53 includes a head, a screw segment and a prism segment connected in sequence. During installation, the connecting bolt 53 is passed from below the flange plate 21, that is, inside the box body 1, so that its head is hidden in the box body 1 and the screw segment passes through the adjustment hole of the bottom plate 51. Then, the connecting nut is loosely tightened to ensure that the connecting bolt 53 does not fall off. When the second bending portion clamps the I-beam 6, the prism segment is held by a wrench to limit the rotation of the connecting bolt 53, and the connecting nut is tightened by another wrench.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
