Abstract
The utility model provides a glass fiber reinforced plastic ladder, which consists of a vertical rod, transverse rods and a connecting assembly, wherein the vertical rod is a cylindrical inner hollow glass fiber reinforced plastic product, and a triangular steel lining is arranged in an inner hollow part of a cylinder; and the transverse rods are square-column-shaped inner hollow glass fiber reinforced plastic products, and the steel lining is arranged in the inner hollow part of the cylinder. The glass fiber reinforced plastic ladder disclosed by the utility model has the advantages of light weight, high strength, corrosion resistance and durability.
Description
Technical field
The utility model relates to a kind of ladder, a kind of specifically glass fiber reinforced plastic ladder.
Background technology
Ladder is the instrument that often uses in people's daily life and the industry, but general ladder all is wooden or steel, all has different defects.Not high, yielding, perishable like wooden ladder intensity, and steel ladder weight is too big, also perishable, on-insulated, be not suitable for the operation relevant with electricity.
Glass fiber reinforced plastic (FRP) also is called GRP, and promptly fiber-reinforced plastic refers generally to strengthen unsaturated polyester, epoxy resin and phenolic resin as matrix resin with glass fiber.Make the reinforced plastic of reinforcing material with glass fiber or its goods, appellation is a glass fiber reinforced plastics, or appellation glass fiber reinforced plastic.Because employed resin kind is different, therefore the title of organic toughened glass, fiber glass epoxy, phenolic fiberglass reinforced plastics is arranged.Glass fiber reinforced plastic had both had the hardness of glass, high temperature resistant, erosion-resisting character, had the equally hard not broken characteristics of iron and steel again, so glass fiber reinforced plastic light weight and hard; Non-conductive; Mechanical strength is high, recycles few, corrosion-resistant; But consider the cost of the pure goods of glass fiber reinforced plastic, we can consider glass fiber reinforced plastic and the compound use of other materials.
Summary of the invention
The purpose of the utility model is in order to overcome the problem that traditional ladder is not corrosion-resistant, weight is big, cost is high, a kind of glass fiber reinforced plastic ladder to be provided.
The technical scheme of the utility model is: a kind of glass fiber reinforced plastic ladder, form by montant, cross bar and connector, wherein montant be cylindrical in empty glass fiber reinforced plastics product, and this cylinder inside is arranged with the triangle steel lining; Cross bar is an empty glass fiber reinforced plastics product in the cubic cylindricality, and should also be provided with steel lining by four directions cylinder inside branch.
Preferably, the cubic cylindricality inside of cross bar is arranged with square steel lining.
Advantage and the good effect that the utlity model has are:
A kind of glass fiber reinforced plastic ladder of the utility model has light weight, cost is low, intensity is high, anticorrosion, long-lived advantage.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the cross-sectional view of Fig. 1 along the A-A direction;
Fig. 3 is the cross-sectional view of Fig. 1 along the B-B direction.
Among the figure:
1, montant 2, cross bar 3, connector
4, triangle steel lining 5, square steel lining
The specific embodiment
Shown in Fig. 1-3, a kind of glass fiber reinforced plastic ladder of the utility model is made up of montant 1, cross bar 2 and connector 3, wherein montant 1 be cylindrical in empty glass fiber reinforced plastics product, and this cylinder inside is arranged with triangle steel lining 4; Cross bar 2 is an empty glass fiber reinforced plastics product in the cubic cylindricality, and this tetragonal body inside is arranged with square steel lining 5.This glass fiber reinforced plastic ladder has light weight, cost is low, intensity is high, anticorrosion, long-lived advantage.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
