second support strips

3, 4 are both channel steel. The first supporting strips 3 and the second supporting strips 4 respectively comprise a long strip-shaped bottom plate and wing plates which are perpendicular to the bottom plate and are vertically arranged on two sides of the bottom plate, so that a shape like a ']' is formed, therefore, a first groove is formed on one side of the first supporting strips 3, a smooth surface is formed on the other side of the first supporting strips, and a second groove is formed on one side of the second supporting strips 4, and the smooth surface is formed on the other side of the second supporting strips.

Bolt holes for the long rod bolts 5 to pass through are further formed at two ends of the first and second supporting bars.

The two ends of the first supporting strip 3 and the second supporting strip 4 are connected through a connecting piece in a pulling and tying mode, so that the first limiting strip and the second limiting strip clamp and limit the steel pipes side by side from two sides. In the present embodiment, the connecting member is a long rod bolt 5, and as mentioned above, the two ends of the first and second supporting bars are provided with bolt holes for the long rod bolt 5 to pass through, and the two ends of the first and second limiting bars (i.e. the first end limiting block and the second end limiting block) are provided with through holes 1-4 for the long rod bolt 5 to pass through. Preferably, the diameter of the bolt hole is consistent with that of the connecting hole, so that when the support bar is subjected to hole forming processing, all the bolt holes and the connecting holes can be processed at one time, hole forming tools with different hole diameters do not need to be prepared for processing the bolt holes and the connecting holes in batches, and processing operation is facilitated.

Meanwhile, the long rod bolt also penetrates through the through holes on the first limiting strip and the second limiting strip, so that the long rod bolt limits the first limiting strip and the second limiting strip in the extending direction of the supporting strips.

As shown in fig. 4 and 5, when a plurality of rows of steel pipes are stacked, because the fixture units are located at the same positions on the corresponding steel pipes, in two adjacent rows of steel pipes, the first grooves of the first support strips 3 of one row of steel pipes face the second grooves of the second support strips 3 of the other row of steel pipes, and because the widths of the first grooves are greater than the widths of the second support strips, the second support strips 4 can be clamped into the first grooves of the first support strips 3, so that the fixture units corresponding to the two adjacent rows of steel pipes are mutually clamped and connected, and the steel pipes are prevented from being damaged due to dislocation in the transportation process. At this time, both sides of the second groove of the second supporting bar 4 abut against the bottom surface of the first groove (i.e. the wing plate of the second supporting bar 4 abuts against the bottom plate of the first supporting bar 3), and the bolt head of the long rod bolt 5 and the nut 6 are all accommodated in the second groove. Therefore, the long rod bolt for connection can be prevented from influencing the first supporting strip to be clamped into the second groove, and the first supporting strip is guaranteed to be abutted to the bottom surface of the second groove, so that the overall thickness of the stacked multi-row steel pipes is reduced to the maximum extent, and the stacked stability of the multi-row steel pipes is improved. And, when needs are for example when carrying out land transportation, sea transportation vanning, the steel pipe level that is arranged side by side is placed, and at this moment, the great first support bar 3 of width is located the downside of steel pipe, and the less second support bar 4 of width is located the upside of steel pipe to stability when can promote the steel pipe level multilayer stack.

Based on the structure, the utility model discloses a steel pipe packing fixture possesses following several advantages: firstly, channel steel with inconsistent width is used as a first support bar and a second support bar, when a plurality of rows of steel pipes are horizontally stacked, a first groove at the bottom of a fixture unit of a row of steel pipes at the upper part is clamped with a second groove at the top of the fixture unit of a row of steel pipes at the lower part, so that the height of adjacent contact surfaces is fully reduced, and more layers can be stacked compared with the prior art under the condition that transportation equipment such as land transportation, sea transportation and the like is limited in height, thereby reducing the transportation cost; meanwhile, the risk that the steel pipe package is toppled possibly caused by ground flatness and wind load in the static stacking and transporting process is solved through mutual clamping of the upper and lower clamp units and enhancement of stacking stability, and the steel pipe package is safe and reliable; thirdly, because rigid steel bar-shaped pieces are adopted as the first and second supporting bars, the supporting strength of the fixture, especially the supporting strength in the length direction of the steel pipe is better, so that for the steel pipe with the same length, the straight line strength and the use requirement of the steel pipe can be met by using fewer fixture units than the prior art, for example, if the laminated wood in the prior art is used as the support, 6 fixture units are needed for fixing a row of steel pipes with the length of 11m, and by adopting the first and second supporting bars in the utility model as the support, the strength requirement can be met by only 4 fixture units for the steel pipe with the same length; meanwhile, the support bar is not easy to damage in transportation, can be recycled, can return along with a vehicle after reaching a client, and is durable and easy for one use.

The present invention may be embodied in several forms without departing from the spirit of the essential characteristics thereof, and the embodiments are therefore to be considered in all respects as illustrative and not restrictive, since the scope of the invention is defined by the appended claims rather than by the description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
