The cross section of the strip-shaped button cap 50 is inverted U-shaped.
More specifically:
A horizontal boom 60 is welded in the left concave cavity 121 of the left semicircular tube 12 and in the right concave cavity 221 of the right semicircular tube 22 for easy lifting.
After the right side of the main road prefabricated panel 10 and the left side of the auxiliary road prefabricated panel 20 are abutted together and the left semicircular tube 12 and the right semicircular tube 22 are combined together in pairs to form a complete circular tube shape, the nut 40 is screwed on the left semicircular tube 12 and the right semicircular tube 22 which are combined together. That is, the nuts 40 connect the left and right half pipes 12 and 22 together, and then connect the main and auxiliary prefabricated panels 10 and 20 together.
The lower side of the left connecting bar 31 presses the upper part of the left extending step 11, the lower side of the right connecting bar 32 presses the upper part of the right extending step 21, the left semicircular tube 12 is positioned in the left concave area 311, the right semicircular tube 22 is positioned in the right concave area 321, the left part of the nut 40 presses the left pressing step 312, the right part of the nut 40 presses the right pressing step 322, and the left connecting bar 31 and the right connecting bar 32 are attached together. That is, the interconnection of the adjacent main road prefabricated panels 10 and the interconnection of the adjacent auxiliary road prefabricated panels 20 are achieved, and the screw cap 40 is supported, so that the structure is more compact. Obviously, the left connecting bar 31 may be provided with a recess for supporting the nut 40, and the right connecting bar 32 may be provided with a recess for supporting the nut 40, and the nut 40 is just clamped in the corresponding recess, so that the connection is more reliable.
The bar-shaped button cap 50 is fastened to the upper portions of the left and right connection bars 31 and 32 attached together. Namely, the function of hiding the components, preventing rain, and the like can be achieved.
In this way, the precast concrete road is laid by precast slabs, and the main road precast slabs 10 and the auxiliary road precast slabs 20 are connected by nuts 40, so that the connection is ensured to be stable and reliable. Meanwhile, the connection between the parts is compact and reasonable, and the integrity of the pavement is ensured.
Optimizing:
The main road precast slab 10 and the auxiliary road precast slab 20 are respectively provided with a plurality of vertically-penetrating adjusting holes 71, the upper diameters of the adjusting holes 71 are smaller, adjusting nuts 711 are fixed on the adjusting holes, and the lower diameters of the adjusting holes are larger to form a large-diameter part 712. It is apparent that the adjustment nut 711 is preferably welded to the corresponding main or auxiliary road reinforcement net 13 or 23. The adjusting nut 711 is internally screwed with a hollow bolt 72, and a plurality of through holes (not shown in the figure) are arranged on the side surface of the hollow bolt 72. Meanwhile, the support blocks 80 made of concrete are pre-buried on the roadbed 100, the lower ends of the hollow bolts 72 are supported on the support blocks 80, and the hollow bolts 72 are filled with concrete slurry 90. That is, once the height is adjusted in place, the concrete slurry 90 is poured into the hollow bolt 72, the concrete slurry 90 flows out of the through hole at the same time, and enters the large diameter portion 712 and the like, and after solidification, the concrete slurry 90 ensures the integrity of the component, at least ensures that the hollow bolt 72 is not easy to rotate and loose, and ensures the continuous stability of the component structure. That is, the distances between the main road prefabricated panels 10 and the auxiliary road prefabricated panels 20 and the corresponding supporting blocks 80 can be adjusted according to circumstances, and after the concrete grout 90 is injected after the adjustment is in place, the adjusted distances are not easily changed, and the flatness of the ground and the stability between the components are further ensured.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the descriptions and drawings of the present invention or directly or indirectly applied to other related technical fields are included in the scope of the invention.
