FIG. 1 is a schematic diagram of the structure of the present utility model;
Fig. 2 is a right side view of fig. 1.
Detailed Description
The technical solution of the present utility model will be further described by means of specific embodiments with reference to fig. 1 and 2.
The polyurethane runway of easy disassembly and recombination as shown in fig. 1 comprises: the polyurethane runway precast block 2 and the positioning framework can be prefabricated in factories, and the convenience of site construction is improved.
In order to improve the anti-slip effect, an anti-slip layer 10 is arranged on the top surface of the polyurethane runway precast block 2. In this embodiment, the anti-slip layer 10 adopts elastic colloidal particles, and the elastic colloidal particles are dispersed on the top surface of the polyurethane runway precast block 2 before the polyurethane runway precast block 2 is precast and cured, so as to realize the fixation of the elastic colloidal particles.
The polyurethane runway precast blocks 2 are sequentially arranged on a positioning framework, the positioning framework comprises two fixing strips 1 which are arranged left and right in parallel, in the embodiment, stepped holes 11 are formed in the fixing strips 1 at intervals, the polyurethane runway precast blocks are conveniently fixed on a base layer through bolts, and the structure is stable. The bottom of the fixing strip 1 can be leveled through the cushion block, so that the requirement on the flatness of the base layer is reduced, and the manufacturing cost of the base layer is reduced.
The bottom surface of the polyurethane runway precast block 2 is concavely provided with an embedded groove 12 corresponding to the fixing strip 1, so that the polyurethane runway precast block 2 can be conveniently arranged and combined in sequence. In this embodiment, the top surface indent of embedded groove 12 is provided with constant head tank 9, be provided with the locating piece 5 that corresponds with constant head tank 9 on the fixed strip 1, the locating piece 5 adopts the rigid plastic structure of integration with fixed strip 1, stable in structure.
