Abstract
The utility model discloses an opening-type square steel tube. A plurality of holes along the length direction are arranged on four walls of the steel tube; the forms of the holes are in an oval shape; the long edges of the oval holes are formed in a vertical square; the short edges are arranged in the horizontal direction. The opening-type square steel tube disclosed by the utility model can be applied to a practical condition in a valid strength experiment; the holes in the wall of the square steel tube are applied to connection under the condition of requirement of the building structure size; a connection plate just needs to be welded on each hole.
Description
Technical field
The utility model relates to a kind of open type rectangular steel tube, belongs to building materials technology field.
Background technology
At present, as the square bar tubing string in building, mainly the form with real abdomen formula occurs, and steel pipe is entity from without, there is no the hole.But in the practical application framework, can have hole on the wall of rectangular steel tube with material saving, not reduce resistance to compression and shear strength simultaneously, paper and Patent from retrieval not yet carry out for the research of this respect.
The utility model content
The utility model provides a kind of open type rectangular steel tube, can overcome above defective, and this steel pipe wall has hole, controls the distance between adjacent holes, makes it not affect the structural strength of rectangular steel tube, and this square steel pipe can the material saving amount.
For solving above technical problem, the utility model provides following technical scheme: a kind of open type rectangular steel tube, have a plurality of holes along its length on the wall of described steel pipe, and hole hole form is oval.
Further, the long edge position of described hole is in vertically square, and minor face is in horizontal direction.
Further, the bond length of described hole is less than 1/4th of the steel pipe walls width.
This open type rectangular steel tube that the utility model relates to can be applied to reality under the experiment of effective intensity.If in the situation that the building structure size needs, make that on the square bar tube wall, the place, hole is applied to connect, only need that junction plate of many welding get final product at porose place.
Description of drawings
Fig. 1 is a kind of open type rectangular steel tube of the utility model structural representation.
The specific embodiment
As shown in Figure 1, have a plurality of holes 2 along its length on the wall of described steel pipe 1, hole 2 hole forms are oval.No matter slotted eye is that resistance to compression or shear resistance are all due to square opening, polygonal hole and circular port.
The long edge position of oval hole 2 is in vertically square, and minor face is in horizontal direction.
The bond length of oval steel pipe 1 is less than 1/4th of steel pipe walls width.
The specific embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection domain of the present utility model.
Claims (3)
