Street floor tile

Abstract

The invention relates to a street floor tile. The street floor tile comprises a hollow tile body, and the peripheral wall of the tile body is provided with flow guide holes; a rotary driven barrel is vertically mounted on an inner bottom plate of the tile body; the outer wall of the rotary driven barrel is provided with shifting teeth, and the inner wall of the rotary driven barrel is threaded; a reset pressure spring is mounted in the rotary driven barrel; a ratchet wheel matched with the shifting teeth externally sleeves the rotary driven barrel, and an impeller sleeves the ratchet wheel externally, coaxially and fixedly; a step plate is mounted on a top plate of the tile body and connected with the tile body through a driving rod vertically penetrating the top plate of the tile body; the driving rod is capable of freely rotating around own axis, one end of the driving rod is connected onto the step plate, and the other end of the driving rod extends into the rotary driven barrel to abut against the reset pressure spring. The street floor tile has the advantages of novel structure, functional diversification and effectiveness in prevention of splashing of water accumulated at tile joints.

Description

technical field [0001] The present invention relates to a road paving material, in particular to a floor tile. Background technique [0002] When planning streets, floor tiles are often laid on the surface of the street. On the one hand, the floor tiles can beautify the street. Most of the time, cement mortar is used to level the ground first, and then the floor tiles are directly laid on the street surface. Because the soil layer under the cement mortar layer is soft, it is easy to deform after being eroded by rain for a long time and pedestrians stepping on it for a long time. Concave-convex deformation occurs on the surface, which leads to poor stability of the floor tiles and weakens the bonding force between the floor tiles and the ground; this causes the floor tiles to loosen; in rainy weather, rainwater accumulates in the depression between the ground and the floor tiles, once pedestrians Stepping on loose floor tiles, the rainwater and sludge accumulated under the...
