Problems solved by technology

[0005] The existing steel pipe racks have a short service life and a high wear rate, resulting in high post-use costs, and the recycling of waste racks leads to secondary environmental damage
[0006] In addition, due to the thicker thickness of the existing steel pipe racking pipes, the weight is relatively heavy, which is not convenient for transportation, and there is a large safety hazard during transportation. The overall weight of the tube system is pressed on the bottom frame tube, which may easily cause the bottom frame tube to be crushed and damaged, endangering the safety of the frame tube system

Embodiment 1

[0032] Take the construction of frame pipes with an outer diameter of 48mm as an example. The production process is:

[0033] S1: Choose a plate steel with a thickness of 3mm and carry out surface treatment. The surface treatment includes smoothing the surface and removing rust on the surface;

[0034] S2: Roll the surface-treated plate to reduce the thickness of the plate, the specific rolling is 2.4mm;

[0035] S3: Testing, testing the thickness of the plate after rolling, if the thickness of the plate after rolling is in the range of 2.4mm-2.5mm, it meets the requirements;

[0036] S4: Pre-bending and bending the tested plates, and curling the plates into a circle through the bending;

[0037] S5: Weld the butt joint of the flange, cut off the excess welding slag, level the surface of the frame, and finally form the finished frame.

[0038] The 3mm plate steel is rolled to a thickness of 2.4mm, and the thickness reduction is in the range of 20%-35%, that is, the thickness of the steel...

Embodiment 2

[0042] Basically similar to Example 1, the difference is that S3: detection, detecting the thickness of the plate after rolling, if the thickness of the plate after rolling is outside the range of 2.4mm-2.5mm, it does not meet the requirements; adjust the S2 rolling For the gap, if the thickness of the plate after rolling is greater than 2.5 mm, the rolling gap is reduced, and if the thickness of the plate after rolling is less than 2.4 mm, the rolling gap is increased.

Embodiment 3

[0044] A kind of frame tube for construction, the material of the frame tube is Q235 or Q345 steel, the thickness of the steel plate material is 2.5-3mm, the steel plate is cold rolled to a thickness of 2mm-2.5mm by cold rolling, and then the cold rolled steel plate is rolled into a tube , And then welded to form.

[0045] Furthermore, the frame tube includes two specifications, namely an outer diameter of 48mm or an outer diameter of 51mm,

[0046] For plates with an outer diameter of 48mm, the thickness is 2mm;

[0047] For a sheet with an outer diameter of 51m, the thickness is 2.4mm.

Abstract

The invention provides a construction frame tube and a frame tube system and a production method thereof. According to the construction frame tube and the frame tube system and the production method thereof, because a process of cold rolling after pressing rolling is used, the raw material cost and the own weight are obviously reduced while the frame tube mechanical property is guaranteed, after asteel plate after the cold rolling is curled into a tube, the nuclear mechanical property (the bending resistant capacity) of the tube is improved about 30% compared with an original Q235 national standard steel tube, about 15-30% of steel materials are saved, the national standard requirements can be completely met, and the better performance can be achieved.

Description

Technical field [0001] The invention relates to the field of construction, in particular to a frame pipe for construction, a frame pipe system and a production method thereof. Background technique [0002] Scaffolding pipe is also called scaffolding pipe, which is what we call the material used to build scaffolding, because most of the scaffolding uses tubular bamboo or steel pipes. There are generally two types of steel pipes used to build scaffolding: one has an outer diameter of 48mm and a wall thickness of 3.5mm; the other has an outer diameter of 51mm and a wall thickness of 3mm. According to its location and function, it can be divided into vertical poles and horizontal poles. Sweeping pole and so on. [0003] Moso bamboo and other bamboos are scaffolding pipes that have been used for a long time. However, due to insufficient safety and durability, they are now only used in small buildings such as self-occupied buildings in rural areas and relatively backward urban areas. I...
