Plastic wood staircase with shock absorption and low noise

Abstract

The invention discloses a plastic wood staircase with shock absorption and low noise. The plastic wood staircase with shock absorption and low noise comprises plastic wood transverse boards and two trusses which are arranged at intervals and in an inclined mode. A plurality of triangular brackets are arranged on the upper surfaces of the two trusses in the length direction of the trusses. At leasttwo protrusions are arranged on the upper surface of the second edge of the each of the triangular brackets. Grooves matched with the protrusions are separately formed in the lower surfaces of the two ends of the plastic wood transverse boards, so that the plastic wood transverse boards are arranged on the protrusions in a clamped mode. A plurality of strip-shaped grooves extending towards the two ends of the plastic wood transverse boards are formed in the plastic wood transverse boards, and the two ends of the strip-shaped grooves communicate with the outside. Fire-proof layers and shock-absorbing layers are arranged on the surfaces, except the surfaces where the strip-shaped grooves are located, of the upper surfaces of the plastic wood transverse boards from top to bottom and in sequence. The plastic wood staircase with shock absorption and low noise has simple installation, safety, environmental protection and effective drainage; the inclination angle can be adjusted, different needs can be conveniently achieved; and the lastic wood staircase with shock absorption and low noise has the advantages of and shock absorption and noise-reducing.

Description

technical field [0001] The invention relates to a ladder, in particular to a shock-absorbing and low-noise plastic-wood ladder. Background technique [0002] Ladders are widely used indoors or outdoors. The traditional ladder structure is usually made of cement mortar. This kind of ladder has the disadvantages of long construction time and not suitable for installation and disassembly. Especially for outdoor floors, it is also necessary to take into account the effect of safety and drainage. [0003] In addition, the traditional ladder structure is more difficult to construct after the house is handed over, and the construction period is long. The ladder made of cement is not hygienic and unsuitable for maintenance without marble or ceramic tiles in the later stage. The noise problem when walking also urgently needs to be solved. Contents of the invention [0004] The object of the present invention is to provide a shock-absorbing and low-noise plastic-wood ladder, which...
