Abstract
The utility model discloses a kind of cross bar of guardrail, include the U-shaped pipe portion of strip, and be integrally connected to the junction plate parallel with inner support plate of U-shaped pipe portion aperture position, described junction plate is connected with two symmetrical shrinking plates on the outer wall of opening side, U-shaped pipe portion, and two shrinking plates are formed and U-shaped pipe portion opening reducing shape in the same way; Described U-shaped pipe portion extends to form one first straight wall portion to U-shaped pipe portion opening towards direction, and the first straight wall portion other end is connected with the first curved wall portion, and the first curved wall portion other end is connected with the second straight wall portion, and the second straight wall portion other end connects the second curved wall portion.By arranging the shrinking plate that two form reducing shape, and the plate that is connected, the first straight wall portion, the first curved wall portion, the second straight wall portion, the second curved wall portion, the connector formed between two shrinking plates can be fastened and connected with the connector on other section bars easily, and ensure that the strength and stability of connection.
Description
Technical field
The utility model belongs to guardrail wires construction applications, is specifically related to the crossbar material structure that a kind of guardrail uses.
Background technology
Rail horizontal rod conventional in prior art as shown in Figure 2, its bottom is in order to be connected with other section bars, adopt when connecting and to be slidably socketed or the mode of snapping connects, A position in fig. 2 easily produces the problem that stress is concentrated, easily damage is produced when adopting the mode of snapping to be connected with other section bars, and easily occur gap after connecting and produce and rock, result of use is undesirable.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provides a kind of firmly rational in infrastructure and more save the rail horizontal rod structure of section bar materials being fabricated.
For realizing the object of the utility model, be achieved by the following technical solutions: a kind of cross bar of guardrail, include the U-shaped pipe portion of strip, between two wing plates being integrally connected to U-shaped pipe portion and the inner support plate parallel with the web in U-shaped pipe portion, and be integrally connected to the junction plate parallel with inner support plate of U-shaped pipe portion aperture position, described junction plate is connected with two symmetrical shrinking plates on the outer wall of opening side, U-shaped pipe portion, and two shrinking plates are formed and U-shaped pipe portion opening reducing shape in the same way; Described U-shaped pipe portion extends to form one first straight wall portion to U-shaped pipe portion opening towards direction, the first straight wall portion other end is connected with the first curved wall portion of an indent, the first curved wall portion other end is connected with a second straight wall portion parallel with the first straight wall portion, the second straight wall portion other end is connected with the second curved wall portion of an evagination, and the second curved wall portion other end is connected with described shrinking plate end arc transition; The angle t formed between two described shrinking plates is 3-5 degree, and the described first straight beeline between wall portion and shrinking plate is the twice of the second straight beeline between wall portion and shrinking plate.
Preferably: the distance between described shrinking plate end and junction plate is the 1/4-2/5 of U-shaped pipe portion's web and junction plate distance; The distance of described inner support plate and junction plate is 1.5-2 times of the web distance in inner support plate and U-shaped pipe portion.
Compared with prior art, the beneficial effects of the utility model are: by arranging the shrinking plate that two form reducing shape, and the plate that is connected, the first straight wall portion, the first curved wall portion, the second straight wall portion, the second curved wall portion, the connector formed between two shrinking plates can be fastened and connected with the connector on other section bars easily, and ensure that the strength and stability of connection, connect between latter two section bar and substantially there is not gap, do not produce and rock.The position be connected with shrinking plate when described shrinking plate position and other section bar snappings all can produce certain deformation, especially distortion by a relatively large margin can be produced in the first curved wall portion position, due to the shape that the first curved wall portion position is indent, be just identical with the direction of deformation, such first curved wall portion can stand larger deformation quantity and not produce damage.

Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
According to Fig. 1, the cross bar of a kind of guardrail described in the present embodiment, include the U-shaped pipe portion 1 of strip, between two wing plates being integrally connected to U-shaped pipe portion and the inner support plate 2 parallel with the web in U-shaped pipe portion, and be integrally connected to the junction plate 3 parallel with inner support plate of U-shaped pipe portion aperture position, described junction plate is connected with two symmetrical shrinking plates, 8, two shrinking plates and is formed and U-shaped pipe portion opening reducing shape in the same way on the outer wall of opening side, U-shaped pipe portion; Described U-shaped pipe portion extends to form one first straight wall portion 4 to U-shaped pipe portion opening towards direction, the first straight wall portion other end is connected with the first curved wall portion 5 of an indent, the first curved wall portion other end is connected with a second straight wall portion 6 parallel with the first straight wall portion, the curved wall portion other end of the second curved wall portion 7, second that the second straight wall portion other end is connected with an evagination is connected with described shrinking plate end arc transition; The angle t formed between two described shrinking plates is 3 degree, and the described first straight beeline between wall portion and shrinking plate is the twice of the second straight beeline between wall portion and shrinking plate.
Distance between described shrinking plate end and junction plate is 2/5 of U-shaped pipe portion's web and junction plate distance; The distance of described inner support plate and junction plate is 1.5 times of the web distance in inner support plate and U-shaped pipe portion.
By arranging the shrinking plate that two form reducing shape, and the plate that is connected, the first straight wall portion, the first curved wall portion, the second straight wall portion, the second curved wall portion, the connector formed between two shrinking plates can be fastened and connected with the connector on other section bars easily, and ensure that the strength and stability of connection, connect between latter two section bar and substantially there is not gap, do not produce and rock.The position be connected with shrinking plate when described shrinking plate position and other section bar snappings all can produce certain deformation, especially distortion by a relatively large margin can be produced in the first curved wall portion position, due to the shape that the first curved wall portion position is indent, be just identical with the direction of deformation, such first curved wall portion can stand larger deformation quantity and not produce damage.
