Technical field
The utility model relates to fixedly structures technical field, discloses a kind of foundation structure, particularly a kind of coke oven base structure.
Background technology
It is the developing direction of coking technology that coke oven maximizes.Introduce the coking technology of USSR (Union of Soviet Socialist Republics) after founding of New, at Anshan iron and steel plant, built the coke oven that the coking chamber height by USSR (Union of Soviet Socialist Republics) design is 4.3m.1971, China seat of honour 5.5m coke oven was constructed and put into operation climbing steel.1985, the 6m M Formed Coke Furnace that China's seat of honour is introduced from Japan was constructed and put into operation at Baosteel.1987, the seat of honour 6m coke oven JN60 type of China's designed, designed was constructed and put into operation in coke-oven plant, Beijing.2010, the seat of honour 6.98m coke oven of China's designed, designed was constructed and put into operation at Angang Bayuquan.Along with the progress of large capacity coke oven coking technology, more and more higher to the requirement of coke oven base structure.
The ultra-large volume coke oven have occupation of land less, high, the Environmental Protection Level of large, the reduced investment of volume, efficiency and level of automation high and realize the characteristics such as energy-saving and emission-reduction, technical progress and the equipment upgrading of Chinese coking industry had to significant meaning.Ultra-large volume coke oven construction characteristics are that coking chamber height and width between centers strengthen, and hole count is many, and the coke oven base roof plate overlength, more than having reached 90m at present.Certain temperature difference being arranged when producing during coke oven basic top plate construction, is to solve thermal stress, and external the employing increases the expansion joint method, increased like this Proper Design and furnace binding complicacy.Take this structure technology, can solve the overlength coke oven base roof plate and not stay expansion joint thermal stress can be controlled in allowed band, both guaranteed the coke oven base security, make again furnace binding simple, save construction investment.
Certain JNX3-70-1 of iron and steel enterprise type multistage heating coke oven, the high 7m of 60 hole carbonizing chamber, length is 93m, width is 16.4m, requires supporting structure not stay in flexible situation in overlength, meets the demand of coke oven technique, equipment and the strain of coke oven base Concrete Structure Temperature.This has just proposed new requirement to coke oven base.
Summary of the invention
The purpose of this utility model is to provide a kind of coke oven base structure, this foundation structure can be born and the effect of satisfied temperature stress and earthquake stress simultaneously, the exploitativeness of security and the construction of the coke oven base structural system that can guarantee to maximize, novel structure, advanced technology, safe and reliable.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of coke oven base structure, this foundation structure is arranged framework, 2 side bars and 1 top board by N and is formed, and described top board is the structure that vertical 93m ultra-long concrete does not stay expansion joint; Laterally minutes four across, often across the post of frame column apart from equating, and middle frame column medullary ray overlaps with the coke oven medullary ray; In N row framework, front 6 row's frame columns at two ends and base plate adopt and are articulated and connected longitudinally, and middle N-12 row frame column adopts with base plate the mode be fixedly connected with.
Described longitudinal framing post post is apart from the distance of getting two coking chamber medullary rays.
Described top board is the integral forming structure that ultra-long concrete does not stay expansion joint.
Compared with prior art, the beneficial effects of the utility model are:
(1) compare with traditional method, effectively utilize space, foundation structure top and the bottom, when the ultra-large volume coke oven, structural system, under the requirement of technique limit for height, limit for width, is achieved process program.
(2) compare with traditional method, take full advantage of the continuity of super-long structural, both met processing requirement, improved again speed of application and construction quality.
(3) with traditional method, compare, this kind of coke oven base structure can be born and satisfied temperature stress and earthquake stress effect simultaneously.
(4) with traditional method, compare, the structural system novelty, stressed clear and definite, the technical progress for ultra-large volume coke oven technique, provide development space.
