Abstract
The utility model discloses a U-shaped cold bending steel sheet piling, which comprises an approximately U-shaped steel sheet body, a left bending body joint and a right bending body joint, wherein the left bending body joint and the right bending body joint are outwardly arranged at the U-shaped opening ends of steel plate body; and the U-shaped steel sheet body, the left bending body joint and the right bending body joint are all formed by steel plates through cold-bending. The utility model has a reasonable structure and high strength, and can greatly improve the bearing capacity of building foundation excavation protection engineering, wharf construction engineering, levee revetment engineering, retaining wall engineering, dock engineering, flow-breaking engineering, bridge building and cofferdam engineering, flood prevention engineering, rollsteinfluten prevention engineering, snowslip prevention engineering and other engineering.
Description
Technical field:
The utility model relates to a kind of steel, especially relates to a kind of novel cold-pressing quality steel sheet pile.
Background technology:
A kind of novel environment friendly steel of steel sheet pile effect, be widely used in engineerings such as the building foundation excavation protects, harbour is built, levee revetment, retaining wall, dock, cutout, bridge construction cofferdam, flood control, anti-mud-rock flow, anti-snowslide abroad, use amount is the gesture of quick growth.According to foreign market survey, global steel sheet pile demand is 2,500,000 tons-3,000,000 tons, and wherein the cold-pressing quality steel sheet pile accounts for 30%, is mainly used in some island countries and the rivers coastline is longer, country, area that the river is more.According to global agent's prediction, Chinese steel sheet pile potential market is bigger, and annual requirement is about 600,000 tons, main cause is that the China sea water front is longer, and rivers and lakes are more, and China is a developing country simultaneously, civil works is more, so the formation of Chinese market is extremely urgent.These novel environmental-friendly construction material steel of steel sheet pile with the very big gap of external existence, are promoted the use of the new demand that steel sheet pile helps adapting to Chinese Water Conservancy, engineering and the development of foundation construction building field in the present annual production of China 10,000 tons of less thaies also.There are problems such as unreasonable structure, intensity is low, bearing capacity is little in common steel sheet pile.
Summary of the invention:
The purpose of this utility model is: a kind of rational in infrastructure, intensity is high, bearing capacity is big U type cold-pressing quality steel sheet pile is provided.
The technical solution of the utility model is: comprise the steel plate body that roughly takes the shape of the letter U and be positioned at steel plate body U-shaped openend outside about curved body joint, about the wrap direction of curved body joint opposite, the curved body joint of one end is rolled over downwards and is had a downward opening, the curved body joint of the other end is upwards rolled over and is had upwards an opening, the steel plate body of U-shaped and about curved body joint adopt steel plate cold bending to process.
The beneficial effects of the utility model are: the steel sheet pile that is formed by clod wash by the high-strength weathering shaped steel plate adapts to the various damage capabilities under the nature, improves the bearing capacity of its structure, does not adopt any preservative treatment, high-efficiency environment friendly.Because its structure is special, it has unique advantage: 1, high strength, light-duty, anticorrosion, water isolating is good; 2, can reuse, generally can use five to eight times; 3, environment protecting is remarkable, reduces in construction and fetches earth and the concrete use; 4, have stronger disaster relief and rescue function, control flood, cave in, subside, express train takes effect in the rescue and relief work of drift sand; 5, construction is simple, and the duration is short, and construction cost is economized.The utility model can improve the bearing capacity of engineerings such as steel sheet pile is built at the protection of building foundation excavation, harbour, levee revetment, retaining wall, dock, cutout, bridge construction cofferdam, flood control, anti-mud-rock flow, anti-snowslide greatly.
Description of drawings:
Fig. 1 is a kind of embodiment of the present utility model;
Fig. 2 is an another kind of embodiment of the present utility model;
Fig. 3 is that embodiment shown in Figure 1 designs the connected mode of using in engineering construction;
Fig. 4 is that embodiment shown in Figure 2 designs the connected mode of using in engineering construction.
The specific embodiment:
From two kinds of embodiments of the present utility model illustrated in figures 1 and 2 as can be seen, the utility model comprise the steel plate body that roughly takes the shape of the letter U 2 and be positioned at steel plate body U-shaped openend outside about curved body joint 1,4, about the wrap direction of curved body joint 1,4 opposite, the curved body joint of one end is rolled over downwards, and the curved body joint of the other end is folding upwards, about curved body joint all have opening, so that be connected to each other, about the opening direction of curved body joint 1,4 opposite, an end upwards, the other end is downward.The steel plate body 2 of U-shaped and about curved body joint 1,4 adopt the clod washes of high-strength weathering shaped steel plate to process, the high-strength weathering shaped steel plate can adopt Q450NQR1.
Fig. 1 is a kind of embodiment of the present utility model, go up wide by 535 * following wide by 270 * high by 162, steel plate thickness 3～16mm.Center line part at the transverse slat 3 of the steel plate body of U-shaped is inwardly recessed.
Fig. 2 is an another kind of embodiment of the present utility model, go up wide by 535 * following wide by 270 * high H162, steel plate thickness 3～16mm.Can bring the intensity about 10～20% to improve by effect of cold work when the cold-pressing quality steel sheet pile is produced, bearing capacity exceeds more than 15% of design bearing capacity.Therefore, under the identical situation of bearing capacity, the cold-pressing quality steel sheet pile can suitably reduce partial component, rod member specification, realizes that the cold-pressing quality steel sheet pile falls heavy target than hot rolled steel plate stake.
The scheme that Fig. 3 uses in design and construction such as building, enclose Haihe River, flood control, anti-soil for the utility model shown in Figure 1, the scheme that Fig. 4 uses in design and construction such as building, enclose coast defence river, flood control, anti-soil for the utility model shown in Figure 2 is buckled together connection mutually.The utility model mainly is applicable to and prevents in corollary failure, occasions such as the convenient construction that social development is taked nature reformation, engineering protection demand and other steel structure bodies and unit construction use.
