Abstract

The utility model provides a truss, which is characterized by comprising four pipe strings 1, transverse ribs 2 and oblique ribs 3, wherein the four pipe strings 1 are arranged in square form whose four sides are fixed by the transverse ribs 2 to limit the position of the oblique ribs 3; two transverse ribs 2 at each side are fixed by an oblique rib 3, to prevent four-link function; the pipe strings 1 are round pipes or square pipes to reduce weight and improve strength. The truss has the advantages of low weight, high strength, standard position of the oblique ribs and easy connection.

Description

A kind of truss

Technical field

The utility model relates to truss.

Background technology

Existing truss is to be welded by metal bar and diagonal bar, and its shortcoming is: weight is big, and intensity is low, and the diagonal bar position is lack of standardization.

Summary of the invention

The purpose of this utility model be to provide a kind of in light weight, intensity big, the truss (comprising Display Rack, lamp bracket etc.) of diagonal bar location specification.

The utility model provides a kind of truss, it is characterized in that: comprise 4 tubing strings 1, horizontal bar 2 and diagonal bar 3,4 tubing string 1 squarelys are arranged, four sides are fixing with horizontal bar 2, and with the position of standard diagonal bar 3,2 of every side two horizontal bars are fixing with diagonal bar 3, prevent four connecting rod effects, tubing string 1 is pipe or square tube, and weight reduction is gained in strength simultaneously.

The truss that the utility model provides, can there be bindiny mechanism 4 one or both ends of its tubing string 1, so that connect between truss.

The truss that the utility model provides, its bindiny mechanism 4 can comprise dististyle 42, bolt 41, sleeve 43 and latch 44, bolt 41 inserts dististyle 42, be with sleeve 43 on the bolt 41, in the pin hole of latch 44 by the hole inserting bolt 41 on the sleeve 43, its dististyle 42 of bindiny mechanism's 4 usefulness is connected with tubing string 1, and the outer end of bolt 41 is connected with the bolt 41 of another bindiny mechanism 4 by the attaching nut.

The truss that the utility model provides, its bolt 41 upper bushes have spring 45 for 43 li, in the pin hole of latch 44 by hole on the sleeve 43 and spring 45 inserting bolts 41, increase the axial compression between each part on the bolt 41, in order to avoid bolt and nut unclamps voluntarily.

The truss that the utility model provides, the profile of its sleeve 43 are six side's or have two parallel planes, so that hold or swivel bolt 41.

The truss that the utility model provides, its bindiny mechanism 4 is cube of framves, and bolt 41 holes are arranged on four sides of frame plate and the outer end, so that use standard component---bolt is connected with another cube frame.

The truss that the utility model provides, its cube frame are to be welded by 12 angle steel, and are welded on the termination of 4 tubing strings 1.

The truss that the utility model provides can be connected with cube connector 5 in its bindiny mechanism 4, comprises that 8 six faces have the square toes 51 of screwed hole and the square bar 52 that there is same bindiny mechanism 4 at 12 two ends, and square toes 51 are threaded with square bar 52.

The truss that the utility model provides, its advantage is: in light weight, intensity is big, and the diagonal bar location specification is convenient to connect.
