Abstract
The utility model discloses a replaceable bituminous street square block, and belongs to a building material, and the replaceable bituminous street square block is mainly applied to maintenance and paving of a bituminous street and is also applicable to other pavements. The replaceable bituminous-street square block comprises a concrete subgrade and a bituminous pavement paved on the concrete subgrade, wherein a plurality of criss-cross reinforcing steel bars are embedded in the concrete subgrade; and a lifting hook is pre-buried in each of four corners of the street square block. The subgrade is built, and then leveled, and then the pavement square blocks are orderly paved. When the pavement is replaced, the damaged pavement square blocks are lifted away by a hoist, and then the new pavement square blocks are mounted after the subgrade is leveled. The replaceable bituminous-street square block has the following advantages: the pavement is formed into a plurality of blocks jointed together and the blocks can be applicable to construction of various pavements; the damaged pavement square blocks can be replaced quickly, conveniently and rapidly; the square block is convenient to repair and the repair quantity can be reduced; the street square block can be recycled after being repaired; and the repair cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of road constructional materials, specifically is a kind of removable asphalt road square.Mainly be applicable to the maintenance and the laying of asphalt road, also be applicable to other road surfaces.
Background technology
Present employed asphalt road mostly is an overall structure, and is easy to be damaged, once the maintenance of damaged back is cumbersome, and keeps in repair and lose time, influences traffic.
Summary of the invention
For addressing the above problem, the utility model provides a kind of removable asphalt road square, and easy to maintenance, labor and material saving is saved time, and member can be recycled, and reduces maintenance cost greatly.
The utility model is realized with following technical scheme: a kind of removable asphalt road square; Comprise concrete substrate and be laid on the asphalt surface on the concrete substrate; Built-in many crisscross reinforcing bars in concrete substrate, each pre-buried suspension hook on four angles of road square.
Carry out roadbed, the road surface square is completed in levelling then in order.When changing the road surface, hang away the road surface square that damages with crane, levelling is installed new road surface square and is got final product.
The beneficial effect of the utility model is: the utility model is processed some pleadings together with the road surface, can be used for the construction on various road surfaces.The road surface square that damages can be changed rapidly, and is convenient and swift; Easy to maintenance, can dwindle maintenance capacity; Can reuse after the maintenance of road square; Maintenance cost is greatly reduced.

Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is the suspension hook structural representation.
Fig. 4 is the bar construction sketch map.
Among the figure: 1, concrete substrate, 2, asphalt surface, 3, reinforcing bar, 4, suspension hook.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the structure of the utility model is further specified.
As depicted in figs. 1 and 2; A kind of removable asphalt road square comprises concrete substrate 1 and is laid on the asphalt surface 2 on the concrete substrate 1; Built-in many crisscross reinforcing bars 3 in concrete substrate 1, each pre-buried suspension hook 4 on four angles of road square.Concrete substrate 1 thickness is 110mm.
As shown in Figure 3, suspension hook 4 is a Ω shape, its underpart to the bending of both sides be embedded in built-in reinforcing bar 3 in the concrete substrate 1 below, the upper end is concordant with the road surface, and and concrete substrate between leave and hang the gap.Present embodiment suspension hook 4 usefulness ￠ 16 galvanizing reinforcing bars are made, and the arc radius R of upper end is 34mm.
As shown in Figure 4, reinforcing bar 3 equates basically that with the concrete base body length present embodiment reinforcing bar 3 length are 4000mm, and there is inside crotch at two ends, and crotch length is 150mm, is used for colluding each other between the reinforcing bar and draws.
