Description

Technical Field

[0001] The present invention relates to the technical field of building materials, and in particular to a road slab, an assembled road and a construction method thereof. Background Art

[0002] In construction sites such as house construction, subway construction, underground pipeline laying, underground sidewalk construction, etc., it is usually necessary to lay temporary roads on the construction site because of the need to transport earth out of the site and to transport various building materials such as steel bars, concrete, bricks, and formwork into the site.

[0003] If excavated soil is used directly for paving, the temporary road will easily become muddy; if concrete is poured for construction, it will not only damage the roadbed but also generate a large amount of construction waste when it is demolished later.

[0004] At present, the use of prefabricated temporary roads can meet the use needs of most construction sites, and the prefabricated road surface is flat and will not generate construction waste. For example, the Chinese patent document with publication number CN106881366A records an assembled road, which includes a shaped steel frame, the shaped steel frame has four corners, and also includes a lifting lug, which can be movably installed on the four corners of the shaped steel frame, and the four corners of the shaped steel frame are respectively provided with lifting lug holes, and the lifting lug can extend from the lifting lug hole. The assembled road recorded in the patent document has the following shortcomings: First, it is inconvenient to build.

[0054] The support bottom plate 111 and the support top plate 112 are both 5 mm thick embossed carbon steel plates, and the support column 113 is a hollow steel column, which is fixed between the support bottom plate 111 and the support top plate 112 by riveting. Figure 3 As shown, the axial centers of adjacent support columns 113 are spaced 200 mm apart, the support columns 113 are densely packed, and the support frame has a strong load-bearing capacity, and can be used for passing concrete tank trucks, trucks transporting slag, and the like.

[0055] Furthermore, a lower steel frame 131 is provided around the supporting frame, and an upper steel frame 132 is provided around the road layer 12. The lower steel frame 131 and the upper steel frame 132 are fixed to the supporting frame. The lower steel frame 131 is made of C-shaped steel, and the upper steel frame 132 is made of angle steel. By providing the lower steel frame 131, the surrounding of the supporting frame is closed to prevent water from entering and causing corrosion of the supporting frame. By providing the lower steel frame 131, the surrounding of the road layer 12 is closed to prevent the edge of the road layer 12 from being damaged, and the laying of the road layer 12 is also convenient.

[0056] The road layer 12 is a permeable road layer, which is formed by paving and pressing environmentally friendly rubber particles bonded with polyurethane. The entire road plate is 150 mm thick, of which the road layer 12 is 30 mm thick. The permeable road layer is easy to wash clean, which is beneficial to road environmental protection.

[0057] like Figure 3 As shown, hoisting holes 121 are respectively provided at the four corners near the road slab, and the hoisting holes 121 penetrate the road layer 12 and the supporting frame, so as to facilitate hoisting when the road slab is used to pave the road.
