Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments of the present disclosure.

Embodiment 1, as shown in fig. 1-3, this embodiment aims at providing a light in weight and can replace the storehouse top purlin of traditional channel-section steel or I-steel, and for this reason, the storehouse top purlin for steel sheet storehouse that this embodiment provided, including the purlin body, in this embodiment, the purlin body is including controlling left side angle steel 1 and the right side angle steel 2 that sets up, be provided with reinforcing plate 3 between left side angle steel 1 and the right side angle steel 2, welded fastening between left side angle steel 1 and right side angle steel 2 and the reinforcing plate 3, constitute the T font setting between left side angle steel 1 and right side angle steel 2 and the reinforcing plate 3. In this embodiment, choose angle steel and add board welding setting for use, and the main reason that does not directly adopt T shaped steel is the general cold drawing or the hot rolling shaping of current T shaped steel, its thick basic unanimity of board, and this just leads to the pressure-bearing can be limited, and constitute the T font setting between left side angle steel 1 and right side angle steel 2 and the reinforcing plate 3, the width of the vertical portion of effectual bin top purlin of increase, thus, its intensity obtains effectual increase, and simultaneously, the width of its top surface also obtains the extension, and then the stress surface increases, thereby ensure intensity, cold drawing or hot rolling mould's resetting has also been avoided like this, corresponding material can be purchased directly on the market, the welding forms, and the production cost is reduced. Finally, by adopting the structure, the specification can be selected to be lower than that of channel steel or I-steel, so that the self weight is reduced, the overall steel consumption of the steel plate bin is reduced, and the construction cost is more economic.

For the convenience of welding, improve the wholeness between left side angle steel 1 and right side angle steel 2 and the reinforcing plate 3, the top surface of reinforcing plate 3 and the top surface level setting of left side angle steel 1, right side angle steel 2, because the top needs support, for this reason, the top surface of whole storehouse top purlin is the horizontal plane, and the bottom surface of reinforcing plate 3 is higher than the bottom surface setting of left side angle steel 1, right side angle steel 2. The construction of welding is facilitated, and the integrity of the purline on the bin top is improved.

In order to further lighten the weight of the purlin body, in the embodiment, the vertical part of the purlin body is provided with the reinforcing holes 4, and the reinforcing holes 4 are arranged on the purlin body at intervals. Strengthen the setting of hole 4, be favorable to the key that alleviates again when the dispersion atress, in addition, still increased the welding point to make the wholeness of purlin body more.

In order to further improve the strength of the purlin body, in the embodiment, a reinforcing rib 5 is arranged between the horizontal part and the vertical part of the purlin body, one end of the reinforcing rib 5 is welded on the left side angle steel 1 or the right side angle steel 2, and the other end of the reinforcing rib is welded on the reinforcing plate 3. The setting of strengthening rib 5 forms the structure setting of triangular supports, has improved the intensity of whole purlin body, and welds the 5 other ends of strengthening rib on reinforcing plate 3, and like this, strengthening rib 5 just need stretch into in strengthening hole 4, like this, can make the more integrated setting of purlin body to ensure the stability of storehouse top purlin, provide the guarantee for its permanent use.

The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
