Description

Technical Field

[0001] The utility model relates to the field of support frames, and more specifically, to an adjustable seamless steel pipe support frame. Background Art

[0002] A seamless steel pipe is a steel pipe formed by piercing a whole round steel, and a steel pipe without a weld on the surface is called a seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, pipe jacking, etc. According to the cross-sectional shape, seamless steel pipes are divided into two types: circular and special-shaped. Special-shaped pipes have various complex shapes such as square, oval, triangular, hexagonal, melon seed-shaped, star-shaped, and finned pipes. The maximum diameter reaches 900 mm, and the minimum diameter is 4 mm. According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes. Seamless steel pipes are mainly used as oil geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.

[0003] For example, a construction steel pipe support frame disclosed in the publication number CN204738558U includes a plurality of vertical rods arranged vertically and in an array, and a plurality of horizontal rods arranged horizontally and in an array. The vertical rods and the horizontal rods are detachably connected. Fine aggregate concrete is poured into each of the vertical rods and the horizontal rods, and a rubber water stop strip is inserted into each of the vertical rods and the horizontal rods. A steel plate water stop ring is welded outside each of the vertical rods and the horizontal rods. By pouring fine aggregate concrete into the vertical rods and the horizontal rods, the strength of the overall support frame is increased; by inserting a rubber water stop strip into the vertical rods and the horizontal rods, and welding a steel plate water stop ring outside the vertical rods and the horizontal rods, the overall support frame can play a waterproof role; the vertical rods are both operating frames and supports for the top surface reinforcement of the slab, which is safe, stable, has strong versatility, good waterproof effect, and can also be used for parts that need to pass through the wall on the exterior wall.

[0004] As can be seen from the above disclosed solution, at present, before welding two steel pipes, it is necessary to limit the positions of the two steel pipes so that the parts to be welded of the two steel pipes are closely attached, and then the welding work is carried out. The limitation of the two steel pipes is mostly carried out by a manually adjustable limiting device. Not only is the limiting stability poor, but it is also not easy to adjust. At the same time, the degree of close attachment at the contact connection of the two steel pipes is manually limited, resulting in a reduced degree of close attachment and affecting the welding effect.
