The pultruded glass fiber reinforced plastic shapes of the utility model is hollow or solid square steel, hollow or solid square steel glass fiber reinforced plastic pole, i iron, channel-section steel or non-conventional glass steel pultruded steel.
A kind of preferred scheme is to mark time by constituting with the pultruded glass fiber reinforced plastic shapes of two above through holes and the pultruded glass fiber reinforced plastic bar that runs through said through hole, perhaps is made up of pultruded glass fiber reinforced plastic bar and the overcoat pultruded glass fiber reinforced plastics hollow pipe on it; Handrail then is a bar overcoat tubular structure.
In order to strengthen the ladder bulk strength; In assembling process, between each pulling and extruding glass fiber section bar, particularly in the through hole; Also available adhesive bonds is firm; As between the pultruded glass fiber reinforced plastic shapes of pultruded glass fiber reinforced plastic bar of marking time and band through hole, perhaps between the pultruded glass fiber reinforced plastic bar of said handrail and the glass fiber reinforced plastic pultruded hollow circular-tube, be provided with adhesive layer.
A kind of scheme is the both sides frame portion of said handrail to be installed and to be equipped with between the said both sides frame portion of marking time angle is arranged.This angle can ladder top and wait to lean between the thing bigger contact area arranged, and make ladder keep in use one fixing, increase stability.
The both sides frame can adopt the pulling and extruding glass fiber section bar of the solid square steel of pultruded glass fiber reinforced plastic, the solid hollow square steel of pultruded glass fiber reinforced plastic or other specifications.
This ladder is that the glass fiber reinforced plastic drawing and extruding section bar by all size model assembles, and only need use the section bar of all size model during making, and assembling gets final product according to customer requirements.A kind of preferred scheme is: the both sides frame adopts the solid square steel of pultrusion, and middle marking time is square steel and bar with two through holes, and handrail is solid pole overcoat hollow circular-tube, and the both sides frame is used dowel fixes; Each material all adopts pultruded glass fiber reinforced plastic material.
The beneficial effect of the utility model:
The utility model can be assembled into the ladder of all size model arbitrarily, in the manufacturing process loss few, energy consumption is low, can effectively reduce production costs, and has improved production efficiency greatly.This ladder light weight is brought construction and easy for installation; Antiseptic property is superior, and the length of service is longer.
