Abstract
The utility model relates to a high-strength steel hoop bar used for construction; a circular high-strength steel material is folded into square, circular or special-shape; both ends of the steel material are welded together and receive quick hot treatment processing, so that the original strength is kept, the overall strength is three times of the common steel bar strength, and the steel material wasted by the overlapped and connected ends of the prior steel hoop bar is saved. The high-strength steel hoop bars can be sleeved on the high-steel bars by batch to be tied into a steel bar cage for concrete casting, and are widely applied to houses, bridges and other buildings, in particular applicable to large buildings, and facilitates for earthquake resistance.
Description
Technical field the utility model relates to high strength steel hoop for construction such as a kind of bridge, house.
Background technology is present, the connection of building the steel bar muscle in the particularly heavy construction is both at home and abroad buckled outside the bundle with iron wire except overlapping in the end, and very big some has begun employing and has been welded to connect, but weld is not generally heat-treated, and all has the problem of strength deficiency.Stirrup muscle particularly, general all as required shape and size, it is square, circular or special-shaped that craft or machinery are converted into, and two ends overlap, with the manual bundle of buckleing of iron wire.Iron wire intensity is little, and under being subjected to the external force effect or earthquake when taking place, very there is huge potential safety hazard in frangibility.In addition, use existing stirrup to have shortcomings such as shearing resistance is less, shock resistance is low, end overlapping connection waste steel, building costs height.
The summary of the invention the purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of high strength steel hoop for construction is provided, and substitutes existing traditional stirrup muscle.
The purpose of this utility model is achieved in that it according to building the different size of stirrup muscle and the requirement of shape, is converted into square, circle or special-shaped with a high strength steel as the muscle body, and the relative butt welding in its two ends is linked together, and forms the stirrup muscle; The automatic butt welding machine of my invention is adopted in welding, during welding, the waste heat that utilizes welding carries out the 1-8 heat treatment of time second in temperature under for 700-1020 ℃ of condition, makes it after welding and heat treatment, the original high-strength characteristic of basic maintenance, bulk strength reaches more than three times of plain bars intensity.
The beneficial effects of the utility model are: (1) the utility model adopts high strength steel to make, weld is through rapid thermal treatment, bulk strength is three times of common iron, during use, can suitably reduce the rugosity of stirrup, add that having reduced the stirrup end overlaps and connect the waste that causes, use the utility model and can save steel about 40% and about 20% cost, make the building increase the safety factor more than a times simultaneously.(2) heat treatment time is short, easy to operate, has advantage energy-conservation, abridged edition.(3) the utility model can use special-purpose machinery geometry and size on demand to carry out mechanization bending and sweating heat processing, can increase work efficiency significantly, and can be mass-produced and wide popularization and application remarkable in economical benefits.(4) the utility model can directly be enclosed within batches on the bar muscle and be bundled into reinforcing cage, and is easy to use; The connection of the bar muscle that is complementary with it also can be used the automatic butt welding machine welding and the heat treatment of my invention.(5) because the bulk strength of high strength steel hoop and bar muscle improves greatly, can increase substantially the intensity and the reliability of building, help antidetonation, guarantee the people's lives and property safety.
Appended drawings 1 is a square structural representation of the present utility model, and accompanying drawing 2 is circular configuration schematic diagrames of the present utility model.
Among the figure: on behalf of hoop body, (2), (1) represent hoop body one end, (3) to represent the hoop body other end, (4) to represent weld.
The utility model will be further described for example below in conjunction with accompanying drawing for the specific embodiment.
Example 1: as shown in Figure 1, the utility model square bar stirrup is made up of square high strength hoop body (1), and the one end (2) and the other end (3) fuse.Add man-hour, with high strength steel as required size be cut into long 81 centimetres one section as hoop body (1), it is converted into square with machinery then, 21 centimetres of the length on one side that two ends (2) and (3) join, each long 20 centimetres on other three limits, then, with the end of one end (2) and the other end (3) mutually on the automatic butt welding machine that is fixed on my invention well, switch on through 5-8 time second and to be heated to temperature more than 950 ℃, weld and form weld (4), immediately weld (4) is carried out 1-5 rapid thermal treatment in second then.The finished product bulk strength is three times of plain bars intensity.
Example 2: as shown in Figure 2, the utility model circular steel stirrup is made up of circular high strength hoop body (1), and the one end (2) and the other end (3) fuse.Add man-hour, with the high strength steel hoop body as required size be cut into long 60 centimetres one section, then it is converted into circle with machinery, then that one end (2) is relative with the other end (3), be fixed on the automatic butt welding machine of my invention, switching on through 5-8 time second is heated to temperature more than 950 ℃, docks welding, form weld (4), and the place of connecing of butt welding immediately (4) carries out 1-5 rapid thermal treatment in second and gets final product.The finished product bulk strength is three times of plain bars intensity.
Claims (1)
1, a kind of high strength steel hoop for construction, be converted into square, circular or special-shaped as hoop body (1) by a high strength steel, it is characterized in that its two ends (2) relative butt welding with (3) links together, weld utilizes the welding waste heat to carry out rapid thermal treatment in welding.
