Abstract
The utility model discloses a kind of metal handrail section bar, include the upper curved wall of an evagination, be connected to the semicircle wall of the evagination of curved wall both sides, the first curved wall of evagination, the surperficial side wall surface for plane in turn, and the lower wall surface be connected with two side wall surfaces of both sides; Described upper curved wall is connected by a concaved circular cambered surface transition with between the first curved wall, and the first described curved wall is connected by a concaved circular cambered surface transition with between semicircle wall, the first curved wall underpart and side wall surface perpendicular; A transversely strengthening wall is connected with between described two side wall surface upper end portions, this metal handrail profile structure of two longitudinal reinforcement walls is also connected with novel between two side wall surface upper end portions and the same side end of upper curved wall, during grasping and hand comes in contact area large, grasp comfortable.
Description
Technical field
The utility model belongs to metal section construction applications, is specifically related to a kind of special profile structure being used as stair or accommodation rail.
Background technique
Existing metal handrail mostly adopts round metal tube, and structural type is single, is difficult to meet the more and more higher individual demand of the people.And it is comfortable not during existing handrail grasping.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provides a kind of novel structure firm, grasps comfortable metal handrail profile structure.
For realizing the object of the utility model, be achieved by the following technical solutions: a kind of metal handrail section bar, include the upper curved wall of an evagination, be connected to the semicircle wall of the evagination of curved wall both sides, the first curved wall of evagination, the surperficial side wall surface for plane in turn, and the lower wall surface be connected with two side wall surfaces of both sides; Described upper curved wall is connected by a concaved circular cambered surface transition with between the first curved wall, and the first described curved wall is connected by a concaved circular cambered surface transition with between semicircle wall, the first curved wall underpart and side wall surface perpendicular; Be connected with a transversely strengthening wall between described two side wall surface upper end portions, between two side wall surface upper end portions and the same side end of upper curved wall, be also connected with two longitudinal reinforcement walls; The radius of arc of described semicircle wall is the 1/8-1/7 of upper curved wall radius of arc; The radius of arc of described semicircle wall is 2-3 times of the first curved wall radius of arc.
Preferably: the described body jointly surrounding a rectangle between two side wall surfaces, lower wall surface and transversely strengthening wall, described lower wall surface internal surface forms two end faces raised line triangular in shape; Be connected with the second curved wall of an evagination between described lower wall surface and side wall surface, described second curved wall and lower wall surface tangent, form the angle of 150 degree between the second curved wall upper end portion and side wall surface.
Compared with prior art, the beneficial effects of the utility model are: this metal handrail profile structure is novel, during grasping and hand comes in contact area large, as snug as a bug in a rug, and form semicircle wall and the first curved wall due to side wall surface top, hand grasps to be not easy to produce and skids, and has higher Security as balustrade.Described rectangular tube is beneficial between adjacent two section bars carries out grafting by the connecting tube of rectangle, during described second curved wall, rectangular tube has certain elasticity, be beneficial to section bar to coordinate closely with connecting tube, described raised line is also the soundness in order to increase grafting.

Fig. 1 is structural representation of the present utility model.
1, upper curved wall; 2, semicircle wall; 3, the first curved wall; 4, side wall surface; 5, the second curved wall; 6, lower wall surface; 7, transversely strengthening wall; 8, longitudinal reinforcement wall.
Embodiment
With reference to the accompanying drawings embodiment of the present utility model is made a detailed explanation below.
According to Fig. 1, a kind of metal handrail section bar described in the present embodiment, include the upper curved wall 1 of an evagination, be connected to the semicircle wall 2 of the evagination of curved wall both sides, the first curved wall 3 of evagination, the surperficial side wall surface 4 for plane in turn, and the lower wall surface 6 be connected with two side wall surfaces of both sides; Described upper curved wall is connected by a concaved circular cambered surface transition with between the first curved wall, and the first described curved wall is connected by a concaved circular cambered surface transition with between semicircle wall, the first curved wall underpart and side wall surface perpendicular; Be connected with 7, two, a transversely strengthening wall between described two side wall surface upper end portions and between side wall surface upper end portion and the same side end of upper curved wall, be also connected with two longitudinal reinforcement walls 8; The radius of arc of described semicircle wall is the 1/8-1/7 of upper curved wall radius of arc; The radius of arc of described semicircle wall is 2-3 times of the first curved wall radius of arc.
The described body jointly surrounding a rectangle between two side wall surfaces, lower wall surface and transversely strengthening wall, described lower wall surface internal surface forms the raised line 9 that two end faces are triangular in shape; Be connected with the second curved wall 5 of an evagination between described lower wall surface and side wall surface, described second curved wall and lower wall surface tangent, form the angle of 150 degree between the second curved wall upper end portion and side wall surface.
This metal handrail profile structure is novel, large with hand comes in contact area during grasping, and as snug as a bug in a rug, and form semicircle wall and the first curved wall due to side wall surface top, hand grasps and is not easy to produce skidding, has higher Security as balustrade.Described rectangular tube is beneficial between adjacent two section bars carries out grafting by the connecting tube of rectangle, during described second curved wall, rectangular tube has certain elasticity, be beneficial to section bar to coordinate closely with connecting tube, described raised line is also the soundness in order to increase grafting.
