Technical field
The utility model relates to a kind of novel coal-stopping wall structure that is used for circular coal storage structure, is widely used in becoming in the various coal storages places such as power plant and colliery.Belong to and construct equipment technical field.
Background technology
At present, circular coal bunker coal-stopping wall master is in being applied to various coal storages places such as power plant or colliery.Recognize that by inquiry present circular coal bunker coal-stopping wall mainly contains two kinds of counterfort formula and monolithics.
Counterfort formula coal-stopping wall is made up of ring foundation, wallboard and buttress, and buttress arranges evenly that along annular build-in is on ring foundation, and the wallboard freely-supported is on buttress and ring foundation, and adjacent two blocks of wallboards separate by deformation joint; The monolithic coal-stopping wall is made up of ring foundation, continuous body of wall and annular back timber, compares with counterfort formula structure, does not establish buttress and deformation joint.
These two kinds of coal-stopping walls are cast-in-place concrete structure, and common shortcoming is that the on-site concrete amount of building is big, long construction period.In addition, counterfort formula coal-stopping wall is owing to the characteristics of not utilizing each member of circular configuration to support mutually cause material usage too much; Though the monolithic coal-stopping wall has remedied this shortcoming of counterfort formula structure, but consequent deficiency is because the spontaneous combustion of coal, very big to concrete wall infringement as main bearing member, because the unreasonable structure of coal-stopping wall integral body, therefore easily cause coal-stopping wall integral body to collapse, there is big potential safety hazard, and, need increases amount of reinforcement for overcoming temperature action because the rigidity of structure is big.
The utility model content
The purpose of this utility model, it is the deficiency that overcomes existing coal-stopping wall form in order to be, a kind of novel coal-stopping wall structure that is used for circular coal storage structure is provided, have construction and easy to maintenance, shorten the construction period, improve the characteristics of anti-coal spontaneous combustion ability of structure and reduction construction costs.
The purpose of this utility model can reach by taking following technical scheme:
Be used for the novel coal-stopping wall structure of circular coal storage structure, its design feature is: be made up of main member and secondary member; Described main member is arranged on the outside of steel plate space enclosing structure, and secondary member is arranged on the inboard of steel plate space enclosing structure; Main member is that notes member and/or prefabricated units form of structure are watered in the scene, and secondary member is a prefabricated units form of structure; Main member comprises ring foundation, buttress and apical ring beam, connects into main body framework by ring foundation, buttress and apical ring beam; Secondary member comprises wallboard, and this wallboard is fixedly connected on the inboard of the main body framework that is connected into by ring foundation, buttress and apical ring beam
The purpose of this utility model can also reach by taking following technical scheme:
A kind of embodiment of the present utility model is: secondary member also comprises ring beam some times, and described time ring beam can be between ring foundation and apical ring beam, and this time ring beam is connected with buttress, and wallboard is connected with time ring beam; Be the secondary ring beam support on buttress, wallboard is supported on time ring beam.
A kind of embodiment of the present utility model is: the ring foundation of main member, buttress and apical ring beam can be the integrated poured structure in scene.
A kind of embodiment of the present utility model is: the ring foundation of main member and apical ring beam can be the cast-in-site structure, the buttress of main member can adopt precast construction, in ring foundation, reserve several cramp joint mouths, the cramp joint mouth that the lower end of some buttresses is inserted ring foundation is respectively fixedlyed connected with ring foundation, and the apical ring beam is fixedly connected on the top of apical ring beam by the mode of cast-in-place shaping.
A kind of embodiment of the present utility model is: described buttress is provided with one for 5 °～10 ° along the every interval of the circumference of ring foundation, arranges 36～72 altogether; Inferior ring beam can be arranged together along highly every 3m～5m as required.
