[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example 1: Plate Insertion Structure

[0023] like Figures 1-4 The prefabricated steel pavement shown includes a base layer and a panel layer.

[0024] The foundation layer includes a subgrade 1, which is a compacted soil base. A square steel elevation band 2 is installed on the subgrade 1. The square steel elevation band 2 consists of several interconnected grid units, each formed by several square steel bars surrounding a single grid. A specific example is a rectangular structure formed by connecting longitudinal and transverse square steel bars, with a transverse spacing of 1.2m and a longitudinal spacing of 1.0m. Mortar 3 is filled between the square steel elevation band 2 and the subgrade 1. A coarse sand leveling layer 4, i.e., a sand cushion layer, is laid on top of the mortar 3. The coarse sand leveling layer 4 is compacted and leveled using a compaction machine, ensuring that the upper surface of the coarse sand leveling layer 4 is flush with the upper surface of the square steel elevation band 2.

[0025] The panel layer includes a bottom panel and a top panel. The bottom panel is installed on the base layer, and the top panel is installed on the bottom panel. The bottom panel is formed by splicing several bottom steel strip panels 5; the top panel is formed by splicing several top steel strip panels 6. The bottom steel strip panels 5 and the top steel strip panels 6 are fixed together by pins 7.

[0026] Specifically, both the bottom steel duct panel 5 and the top steel duct panel 6 are regular hexagons of the same size, with an example angle length of 1.498m. Corresponding to the size of the grid unit of the square steel elevation band 2, this ensures that at least a portion of each bottom steel duct panel 5 presses against the square steel, thus allowing the square steel to bear the pressure of the panel layer and preventing subsidence and deformation during use. Furthermore, the center of each top steel duct panel 6 is located at one vertex of the bottom steel duct panel 5, and one vertex of each top steel duct panel 6 is located at the center of the bottom steel duct panel 5, meaning the bottom and top steel duct panels 5 are installed in a staggered manner. Both the bottom and top steel duct panels 5 and 6 are equipped with corresponding pin cylinders 12, with pin shafts 7 passing through the pin cylinders 12. Each top steel duct panel 6 is fixed to three bottom steel duct panels 5 via pin shafts 7.

[0027] In this example, the bottom steel duct panel 5 and the top steel duct panel 6 are installed by interlocking and pinning with each other through staggered installation and fixing with pin 7, achieving the goal of eliminating panel gaps and avoiding the impact of accumulated errors. Fixing with pin 7 also allows for quick replacement of duct panels, enabling them to be reused.

[0028] In the example, the bottom steel pavement panel 5 and the top steel pavement panel 6 each include an outer frame 8, one side of the outer frame 8 is provided with a cover plate 9, a plurality of rib plates 10 are connected in the outer frame 8, and the outer frame 8 is filled with foamed concrete, and the surface of the foamed concrete is flush with the outer frame 8. The foamed concrete can greatly reduce the self-weight of the single steel pavement panel, facilitate the storage and on-site paving construction of the steel pavement. The cover plate 9 of the bottom steel pavement panel 5 is located at the bottom thereof and is used to support the entire assembled steel pavement, and the cover plate 9 of the top steel pavement panel 6 is located at the top thereof and is used as a running track pavement.

[0029] The bottom plate and the top plate further include irregular steel pavement panels around the periphery, and the edges of the bottom plate and the top plate are flush.

[0030] In addition, the edge of the bottom steel pavement panel 5 is further provided with a positioning hole 11, and three adjacent positioning holes 11 at the joint part of every three bottom plates are fixed by using a positioning plate during construction.

[0031] The construction steps of the assembled steel pavement of the embodiment are as follows:

[0032] 1. Construction of the leveling layer elevation belt

[0033] On the compacted soil base, a square steel elevation belt is installed, the transverse spacing of the square steel elevation belt is 1.2 m, and the longitudinal spacing is 1.0 m. The gap between the square steel elevation belt and the compacted soil base is filled with mortar.

[0034] 2. Construction of the leveling layer

[0035] The coarse sand leveling layer is laid in the square steel elevation belt, and the sand cushion layer is compacted and leveled by using a compactor.

[0036] 3. The foamed concrete is filled in the steel pavement panel, and the top surface of the concrete is flush with the surface of the steel profile. The compressive strength of the concrete is not less than 3 MPa, and the dry density is less than 800 kg / m3.

[0037] 4. Laying of the tooling

[0038] The simple assembly trolley is used to form a lifting tool, and five magnet blocks are arranged on the lifting tool. The magnet blocks are located in the middle of the steel pavement panel and the middle of the rib plate, so that the steel pavement panel can always maintain a horizontal state during hoisting, and the joint control and pin shaft installation are facilitated.

[0039] The simple assembly trolley can reduce the labor intensity of the operator during installation by using the lever principle.

[0040] The magnet adsorption mode is used for auxiliary installation, and no lifting point needs to be arranged on the steel pavement panel, which reduces the processing workload and saves the on-site assembly time.

[0041] 5. Laying of the bottom plate

[0042] The steel cover plate of the magnet adsorbed steel pavement top layer plate is used to install the steel pavement top layer plate of the steel pavement in sequence.

[0043] 6. Install the positioning plate

[0044] After installing the three bottom layer plates, the positioning plate is fixed in the three adjacent positioning holes at the joint of every three bottom layer plates.

[0045] 7. Remove the positioning plate in the range of the single top layer plate to be paved in sequence.

[0046] 8. Install the positioning pin shaft

[0047] At least two pin shafts are installed on the bottom layer plate in the range of the single top layer plate to be paved as the positioning reference of the top layer plate.

[0048] 9. Pave the top layer plate

[0049] The steel cover plate of the magnet adsorbed steel pavement top layer plate is used to install the steel pavement top layer plate of the steel pavement in sequence.

[0050] 10. Install the positioning pin shaft between the bottom layer plate and the top layer plate.

[0051] Six pin shafts are installed between the bottom layer plate and the top layer plate.

[0052] 11. Install the irregular plate around the steel pavement

[0053] The steel pavement plate around the irregular part of the top layer plate and the bottom layer plate is installed to ensure that the four sides of the steel pavement are flush and linear.

[0054] 12. Fill the top surface of the positioning pin with silicone

[0055] The top surface of the pin shaft is filled with silicone to reduce the dust entering the gap between the pin shaft and the steel pavement plate.

[0056] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and its equivalents.
