TECHNICAL FIELD

[0001] The utility model relates to steel bar truss technical field, in particular to single upper chord double lower chord same side single web pole bar muscle's plane truss. BACKGROUND

[0002] At present, the existing ordinary steel bar truss is all single upper chord, two lower chords, and each has a web pole bar muscle on the left and right sides, but this can cause low supporting strength, easy deformation, and is not conducive to use, therefore we propose single upper chord double lower chord same side single web pole bar muscle's plane truss. SUMMARY

[0003] In order to overcome the insufficient prior art, the utility model provides single upper chord double lower chord same side single web pole bar muscle's plane truss, can solve the technical problem mentioned in the above background.

[0004] In order to solve the above technical problem, the utility model provides the following technical scheme: single upper chord double lower chord same side single web pole bar muscle's plane truss, including upper chord, web pole bar muscle, angle and lower chord, the upper chord is located at the end of web pole bar muscle, and the upper chord is fixedly connected with web pole bar muscle, the angle is located at the other end of web pole bar muscle, the lower chord is located below the upper chord, and the lower chord is fixedly connected with web pole bar muscle.

[0005] Preferably, the lower chord is provided with two and is located at the bottom of the web pole bar muscle respectively.

[0006] Preferably, the web pole bar muscle and the upper chord welding point are in the left side of the upper chord.

[0007] Preferably, the inclination angle of the angle is forty degrees, and the vertical distance between the bottom of the angle and the lower chord is 15mm.

[0008] Compared with the prior art, the utility model can reach the beneficial effects that are:

[0009] Single web pole bar muscle left and right with angle and angle downward fold about 40 degrees, the vertical distance between the bottom of angle and lower chord muscle is 15mm, the welding point of web pole bar muscle and upper chord is all in the left side of upper chord, and the two lower chord muscles are tightly clamped in the left and right sides of web pole bar muscle, so that high strength free support can be realized.

[0013] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0014] Example:

[0015] like Figs. 1-2 As shown, a planar truss with a single top chord, double bottom chords, and a single web member on the same side includes a top chord 1, a web member 2, a slant 3, and a bottom chord 4. The top chord 1 is located at the end of the web member 2 and is fixedly connected to the web member 2. The slant 3 is located at the other end of the web member 2. The bottom chord 4 is located below the top chord 1 and is fixedly connected to the web member 2.

[0016] Specifically, there are two lower chords 4, located on the bottom sides of the web reinforcement 2 respectively.

[0017] Specifically, the weld point between the web reinforcement 2 and the upper chord 1 is on the left side of the upper chord.

[0018] Specifically, the tilt angle of the left-falling corner 3 is forty degrees, and the vertical distance between the bottom of the left-falling corner 3 and the lower chord 4 is 15mm.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
