Figure 4 for image 3 Enlarged view of part A. Figure 5 It is a top view of an exemplary structure of prefabricated concrete beams in the prefabricated concrete structure layer of Embodiment 1 of the present invention, Image 6 It is a top view of the partial assembly effect of the prefabricated concrete structure layer in Embodiment 1 of the present invention.
[0033] Such as Figure 1 to Figure 5 As shown, the prefabricated concrete structure layer mainly includes: a plura...
Embodiment 2
[0041] Figure 7 It is a schematic diagram of the fixing method of the prefabricated concrete structure layer according to the second embodiment of the present invention. On the basis of Example 1, as Figure 7 , Figure 5 and figure 1 As shown, in the prefabricated concrete structure layer of this embodiment, the prefabricated concrete beam 12 is provided with a through hole 122 corresponding to the position of the fixing rod 111 . For example, the fixing rod 111 is a bolt or a screw rod, and a bolt hole matching the fixing rod may be reserved in the prefabricated beam.
[0042] In one possible implementation, such as figure 1 and Figure 5 As shown, the fixing rod 111 passes through the corresponding through hole 122 to fix the precast concrete beam 12 on the step structure 110 .
[0043] In one possible implementation, such as Figure 7 As shown, the upper part of the through hole 122 in the prefabricated concrete beam 12 has a fixing groove 123, and a gasket 124 is in...

[0046] Figure 8 It is a flow chart of the assembly method of the prefabricated concrete structure layer according to the third embodiment of the present invention. like Figure 8 As shown, for the prefabricated concrete structure layer of any structure in the above-mentioned embodiment, its assembly method may include:
[0047] Step 801, hoisting multiple precast concrete slabs to designated positions in the construction area;
[0048] Step 802, lifting a plurality of precast concrete beams above the plurality of precast concrete slabs, and placing the plurality of precast concrete beams on both sides of the plurality of precast concrete slabs;
[0049] Step 803, after leveling and fixing the precast concrete slab and the precast concrete beam, dismantling the precast concrete slab and the precast concrete beam above the step structure of the spreader;
[0050] Step 804, perform grouting through the installation tunnel of the spreader.
[0051] Specifically, prefabricated...
