Abstract
The invention provides a corner bend for an aluminum alloy bridge frame. The corner bend is used for an ocean engineering platform and comprises wall beams on two sides, the wall beam on the left side is formed by enabling a first side wall to be connected with a second side wall, an included angle between the first side wall and the second side wall is an obtuse angle, the wall beam on the right side comprises a third side wall, the length of the third side wall is smaller than that of the first side wall, the first side wall is parallel to the third side wall, the outer end of the second side wall is positioned on the horizontal extending line of the first side wall, an opening is arranged between the outer end of the second side wall and the third side wall, a vertical ledge is arranged in the opening, and a horizontal ledge perpendicular to the vertical ledge is arranged between the vertical ledge and the first side wall and the second side wall. The corner bend for the aluminum alloy bridge frame has the advantages of being simple in structure, high in intensity and light in weight, having the service life as long as forty years and enabling the manufacturing cost to be relatively lowered.
Description
Technical field
The present invention relates to supply the crane span structure device field in the distribution, it is curved logical especially to relate to a kind of aluminum alloy crane span structure corner.
Background technique
Crane span structure is the support of a support and payout.It is very general that crane span structure is used on engineering; As long as cable laying will be used crane span structure, cable testing bridge does not still have special standard at present and instructs as a supporting project of wiring installation; The specification formula of individual manufacturer lacks versatility; Existing cable testing bridge mostly has the bulk metal framework to process, and overall structure is heavy, and cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, intensity is high, the aluminum alloy crane span structure corner of in light weight, long service life, low cost of manufacture is curved logical.
Technological scheme of the present invention is:
Aluminum alloy crane span structure corner is curved logical; Be used for the ocean engineering platform, comprise the two side beam, said left side wall beam is formed by connecting the first side wall and second sidewall; And the angle between said the first side wall and said second sidewall is the obtuse angle; Said right side wall beam comprises the 3rd sidewall, and the length of said the 3rd sidewall is less than said the first side wall, and said the first side wall and said the 3rd sidewall parallel; The external end head of said second sidewall is on the horizontal elongation line of said the 3rd sidewall; Between the external end head of said the 3rd sidewall and said second sidewall opening is set, is provided with vertical crosspiece in the said opening, between said vertical crosspiece and said the first side wall and said second sidewall, be provided with the horizontal crosspiece vertical with said vertical crosspiece.
Further, said vertical crosspiece is one to three.
Further, said horizontal crosspiece is five to nine, and all said horizontal crosspieces link to each other with said vertical crosspiece.
Further, said vertical crosspiece and said horizontal crosspiece are the flat hollow tube.
Further, said vertical crosspiece and said horizontal crosspiece are provided with through hole.
Further again, said through hole is a strip hole, and the long limit of said strip hole and said vertical crosspiece or said horizontal crosspiece are perpendicular.
Advantage and good effect that the present invention has are: simple in structure, intensity is high, in light weight, reach 40 years working life, manufacture cost reduces relatively.

Embodiment
As shown in Figure 1; Entire body of the present invention is that aluminum alloy material is made, and comprises the two side beam, and said left side wall beam is formed by connecting the first side wall 1 and second sidewall 2; And the angle between said the first side wall 1 and said second sidewall 2 is the obtuse angle; Said right side wall beam comprises the 3rd sidewall 3, and the length of said the 3rd sidewall 3 is less than said the first side wall 1, and said the first side wall 1 is parallel with said the 3rd sidewall phase 3; The external end head of said second sidewall 2 is on the horizontal elongation line of said the 3rd sidewall 3; Between the external end head of said the 3rd sidewall 3 and said second sidewall 2 opening 4 is set, is provided with vertical crosspiece 5 in the said opening 4, between said vertical crosspiece 5 and said the first side wall 1 and said second sidewall 2, be provided with the horizontal crosspiece 6 vertical with said vertical crosspiece 5.
Said vertical crosspiece 5 is three.
Said horizontal crosspiece 6 is seven, and all said horizontal crosspieces 6 link to each other with said vertical crosspiece 5.
Said vertical crosspiece 5 is the flat hollow tube with said horizontal crosspiece 6.
Said vertical crosspiece 5 is provided with through hole 7 with said horizontal crosspiece 6.
Said through hole 7 is a strip hole, and the long limit of said strip hole and said vertical crosspiece 5 or said horizontal crosspiece 6 are perpendicular.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
