Description

Double Truss Structure {DOUBLE TEE TRUSS STRUCTURE}

The present invention relates to a double truss truss structure, and in particular, to ensure that the double tee of the same type is coupled to the coupling groove provided in the upper and lower portions of the bracing portion, to support a high load or to enable a long span truss.

In general, the truss refers to a skeleton structure in which several linear members are connected at the nodes so that one or more triangular members are arranged in a triangular shape. The truss is composed of upper and lower chords, vertical members and yarns, and is commonly used in construction or civil engineering structures.

As the upper and lower chords of the truss are axially stressed, the larger the distance between the centers of the upper and lower chords, the less the axial stresses, while the stiffness of the trusses increases. In addition, the upper and lower chords subjected to the compressive force are determined by the three pieces of equipment, As the main shaft thinner and the minor shaft thinner by the buckling interval of the compressive material restrained by the member installed in the perpendicular direction of the truss are approximated, the efficiency of the member increases.

For this reason, the conventional truss has been the most economical to use two angles as the upper current or lower current, but because of the limited size of the angle is not suitable for high load or long span truss and has the disadvantage of difficult to prevent corrosion and fire-resistant paint.

When single tee steel is used as the top and bottom chords of the truss, the ready-made stem (web) has a width-to-thickness ratio exceeding the allowance and the section efficiency is reduced. Therefore, there is a technique of constructing a truss with a tee-shaped section made by welding a thick steel plate, but a heavy load truss is not suitable due to the disadvantage of manufacturing cost of the cross section and installing a separate member to control out-of-plane buckling. not.

If the truss is composed of a round steel pipe, the weight is relatively light, but the second-order radius of the two axes is the same, so that the spacing of the booters determines the member strength, so that the efficiency is lowered, and the strength against bending is small, which is not suitable for high load or long span. Therefore, in the case of a long span truss, a triangular steel pipe truss which is composed of two steel pipes, which is compressed and has a high current or a low current, is widely used. Therefore, the local stress in the main pipe is considerably generated, and the application of a large amount of vertical or sand axial force is limited, and it is difficult to carry along with the increase in cost since it must be transported by welding at the factory. There is an under tension structure that tensions the lower part of the steel pipe truss to apply to the long span, but the cost of the tension increases.

 Conventional high load trusses generally use H-beams as top or bottom chords, but in the case of long spans, stress due to the truss own weight is considerable, resulting in a problem of low efficiency.

In the present invention, two constituting the double tee

Figure 112010052236621-pat00001
By increasing the stiffness by increasing the efficiency of the cross section by bringing the center of the cross section closer to the flange, the high load is supported and the long span can be supported at the same time.

In the present invention, the bracing part 20 is coupled to the coupling groove 12 formed in the double tee part 10 of the upper and lower parts of the double tee part 10 having the same shape as the upper and lower parts of the bracing part 20. In the double tee truss structure, the upper and lower double tee 10 have two

It is characterized by consisting of any one of.

In the present invention, by increasing the cross-sectional efficiency of the double tee to increase the truss rigidity, it is possible to obtain the effect that the high load is supported and the long span can be stably supported.

In addition, by allowing the cross-sectional secondary radius to be enlarged on the outside of the double tee, it is possible to obtain an effect of reducing the member while reducing the effect of lateral buckling.

In addition, it is possible to use the ready-made products through this, it is possible to obtain the effect of reducing the production cost while maintaining the supply and demand smoothly to increase the reliability of the strength.

In this way, the truss can be easily manufactured, transported, and installed, thereby reducing work time and cost.
