Description
Technical field
The utility model relates to Hydraulic and Hydro-Power Engineering, particularly and a kind of power station crucible shell support structure of steel die.
Background technology
Power station crucible hull shape body is similar to hodmadod, and it act as water inlet impact current and redistributes by changing modes such as fluidised form in the crucible shell, and it is imported seat ring, impacts the stator rotation and the conversion of generation magnetoelectricity.According to " powerhouse of hydropower station design specifications " (SD335-89) regulation of 4.3.21 bar, the crucible shell is divided into two kinds on metal crucible shell and steel concrete crucible shell, when head appropriate to the occasion employing metal crucible shell more than 40m; If adopt steel concrete crucible shell, the Technological Economy authentication should be arranged then.Two kinds of basic combination of steel concrete crucible shell bearing load combination branch and specific combination, basic combination: dead load+machine pier transmits load+turbine floor load+internal water pressure+external water pressure; Specific combination need consider also that the external water pressure under internal water pressure off-load under the crucible shell emptying state, the check flood state increases and the variations in temperature condition under situations such as thermal stresses variation, its critical role and bearing load situation have determined must to guarantee the smooth-going of the accuracy of crucible housing shape and body in work progress, be the emphasis and the difficult point of the construction of powerhouse of hydropower station engineering second stage concrete.
The traditional handicraft of wooden form+combined steel formwork on-site consolidation is adopted in the conventional construction of steel concrete crucible shell, and the job practices of traditional wooden model processing+combined steel assembly unit has following characteristics and shortcoming:
(1) skilled worker's professional standards of Yao Qiuing, qualification height, quantity is more, and has experience or the experience of being engaged in similar construction;
(2) technological service will put in place, can not make mistakes
To measuring setting-out, putting a required precision height, need the all-the-way tracking service; The workload of doing over again that produces of going wrong is big, causes the serious waste of duration, material resources and manpower, has a strong impact on the duration.
(3) long construction period
Because influences such as complexity, the narrow and different specialties in machine crucible construction operation place, the operation operation of crucible shell structure intersect mutually, steel concrete crucible shell is because of the temperature requirements construction in layer, it is big that interlayer is connected difficulty, adopt the method construction period of traditional wooden model processing, assembly unit inevitable longer, the COMPREHENSIVE CALCULATING separate unit crucible shell construction period is no less than 2.5 months, and it is long in time limit to take straight line.
(4) bodily form is difficult for guaranteeing
Conventional steel reinforced concrete crucible shell job practices is many owing to wooden form assembly unit slit, plank rigidity is less relatively, the limit inner corner trim is difficult for reasons such as construction, the crucible shell morphology easily produces distortion during concreting, the time faulting of slab ends arranged, run mould, quality problems such as spillage take place, later stage defect processing workload is big, the difficulty height.
(5) construction cost height
The high material consumption that the crucible shell job practices of the processing of tradition wooden model, assembly unit causes, particularly all the more so to difficult timber of regenerating, steel pipe etc., and be difficult to turnover utilization, the construction cost stand disappears greatly.
The utility model content
At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of power station crucible shell to support structure of steel die, and the construction simple and fast, bodily form quality is guaranteed and can repeatedly have enough to meet the need use, cost is low.
The technical solution of the utility model is: a kind of power station crucible shell supports structure of steel die, connect and compose by a plurality of template systems unit, wherein each template system unit comprises crucible shell profiled template, and the support system that supports profiled template, wherein profiled template comprises the last oblique mould that from top to down forms the semi-surrounding structure from left to right around support system, backform, side form and declivity mould, support system comprises the left and right sides i iron door frame column that is fixed on the crucible shell bottom board concrete face, be connected and fixed on the door frame crossbeam between the door frame column of the left and right sides, and the lumps of wood, adjustable supports and adjustable diagonal brace, wherein the door frame crossbeam comprises top rail, middle cross beam and lower transverse beam, and top rail is fixed by adjustable supports and adjustable diagonal brace and left and right sides door frame column, between the door frame column between adjacent forms system unit and between each profiled template connection is arranged all, wherein going up oblique mould is supported on the left-hand door frame column by adjustable diagonal brace connection, backform connect to be gone up oblique mould and side form and is connected on the top rail by the channel-section steel secondary beam, side form is connected on the right door frame column by the channel-section steel secondary beam, and the declivity mould stands on the crucible shell bottom board concrete face and by the lumps of wood and left-hand door frame column and is connected and fixed.
The beneficial effects of the utility model are: the utlity model has accelerating construction progress, save duration, the bodily form, quality is guaranteed and can repeatedly have enough to meet the need distinguishing feature such as use, innovation point such as have pre-assembly unit simultaneously, can regulate, application prospect is very wide, the promotional value height.
