Description

The square tube with holes of iron skill fence and use thereof

Technical field

The utility model relates to a kind of fence structure, also relates to a kind of rhs-structure.

Background technology

Do the with a long history of fence with steel, what have uses angle bar round steel, also useful cast iron materials manufacturing.In recent years, major part is made with the iron square tube, adds some the casting ornamental work of iron or punching press ornamental work of irons, just is called iron skill fence.This fence cost is low, easy for installation, has therefore obtained using widely.

As shown in Figure 1, be a kind of structural representation of existing iron skill fence, it is between two upright square tubes, with the square tube transverse weld connection of uniform thickness.Adopt such structure, need a lot of short square tubes to do horizontal connection, need a large amount of work that cuts and welding job, obvious time-consuming taking a lot of work, and the fence that is made into exists a large amount of pads, not only influences attractive in appearancely, and the structural strength of fence also has been lowered.

Again as shown in Figure 2, it is the structural representation of another kind of existing iron skill fence, it is the both sides in upright square tube, each transverse weld has several pieces band irons, these band irons need not cut into shorter length, but have a large amount of solder joints equally, time-consuming taking a lot of work, also being heated easily produces distortion, influences attractive in appearance and structural strength fence.

For this reason, the applicant is desirable to provide a kind of iron skill fence, reduces the manufacture difficulty of iron skill fence, increases work efficiency.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model is: the square tube with holes of a kind of iron skill fence and use thereof is provided, simplifies the connection technology of iron skill fence, when reducing the Welder, improve the appearance property of iron skill fence.

For achieving the above object, the technical solution adopted in the utility model comprises:

A kind of iron skill fence, it is characterized in that: it is provided with the square tube with holes that at least two rows are parallel to each other, on two sides that are parallel to each other of this square tube with holes respectively punching press several square holes are arranged, and the position of the square hole on these two sides that are parallel to each other is corresponding mutually, ordered series of numbers connects square tube and wears and fix in the square hole of this square tube with holes, and this connection square tube intersects vertically to connect into fenestral fabric with this square tube with holes.

In a preferable technical scheme: this connect square tube with the outside dilatancy in square hole junction of square tube with holes, thereby forming to fix with the square hole of this square tube with holes is connected.

In a preferable technical scheme: the size of each square hole is identical with the sectional dimension that this connects square tube.

In a preferable technical scheme: the sectional dimension of this square tube with holes is 20mm * 40mm, and the sectional dimension of described connection square tube is 20mm * 20mm, and the size of the square hole of punching press also is 20mm * 20mm on this square tube with holes.

In a preferable technical scheme: the square hole junction of this connection square tube and square tube with holes also is welded to connect.

For achieving the above object, the technical solution adopted in the utility model also comprises:

A kind of square tube with holes is characterized in that: on two sides that are parallel to each other of this square tube with holes respectively punching press several square holes are arranged, and the position of the square hole on these two sides that are parallel to each other is corresponding mutually.

In a preferable technical scheme: the sectional dimension of this square tube with holes is 20mm * 40mm, and the size of the square hole of punching press also is 20mm * 20mm on this square tube with holes.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be:

1, manufacturing process is simple, and it is time saving and energy saving to install, and has improved operating efficiency;

2, need not to cut, square tube still is kept perfectly, and the overall construction intensity of fence is good;

3, need not welding or the only a small amount of welding of do, saved installation work-hour, and owing to do not have solder joint or solder joint seldom, also do not had temperature distortion, the fence good looking appearance of producing is generous.

The specific embodiment

As shown in Figure 3, Figure 4, the utility model provides a kind of iron skill fence, and it is provided with the square tube with holes 10 that at least two rows are parallel to each other, and ordered series of numbers connects square tube 20 and intersects vertically mutually to connect into fenestral fabric with this square tube 10 with holes.

In the present embodiment, the square tube that this square tube 10 with holes is 20mm * 40mm, the size of described connection square tube 20 then is 20mm * 20mm, two parallel side 11 upper punches of this square tube 10 with holes are pressed with several paired square holes 12, the size of each square hole 12 is identical with the sectional dimension that this connects square tube 20, also is 20mm * 20mm.

As for the making of this square tube 10 with holes, can be directly square tube to be placed on the punch press, stamp out paired square hole then, this method is suitable for small lot batch manufacture; Also can stamp out the symmetric double hole on the band steel, roll into square tube then, this method is suitable for producing in enormous quantities.

When installing, from the square hole of square tube 10 with holes, pass, manage then to make to connect square tube, be connected thereby form fixing with the square hole 12 of square tube 10 with holes in the outside dilatancy of link position with connecting square tube 20.As for above-mentioned expanding method, only do concise and to the point the description herein, be in connecting square tube 20, to stretch into an expansion-head, the width of this expansion-head connects between the catercorner length of the length of side of endoporus of square tube 20 and this endoporus between this, the application of force rotates a circle this expansion-head then, can will connect square tube 20 outwards strut distortion corresponding to the position of this expansion-head, be connected with the formation fixing.Fix after the connection, more firm in order to guarantee connection, can also weld on a small quantity at the link position that connects square tube 20 and this square tube 10 with holes.

Hence one can see that, uses the iron skill fence of this structure, has following advantage:

2, need not to cut, it is complete that square tube still keeps, and the overall construction intensity of fence is good;

More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, in the situation that does not break away from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
