Description
Technical Field
The utility model relates to a wind power fan foundation, in particular to a prefabricated assembly beam plate type fan foundation.
Background
At present, a wind power market often adopts a cast-in-place extension foundation on the basis of a natural foundation fan, so that an ideal economic and technical effect is difficult to obtain, the construction quality in a severe cold area is difficult to guarantee, the construction progress is slow, the construction period of a wind power project is difficult to guarantee, and the burden of the environment is increased. At present, the following defects exist in common expanded foundations and cast-in-place beam-slab fan foundations:
1) the expansion foundation is widely applied to natural foundations, the concrete consumption is large, and pouring difficulty exists in foundation construction in severe cold areas.
2) For enlarging the plate type fan foundation in the conventional cast-in-place design, the beam plate type fan foundation can save the concrete consumption, but the defects of difficult formwork support, small steel bar interval, difficult vibration and compaction of concrete, slow construction progress and the like exist simultaneously.
Disclosure of Invention
In order to solve the problems in the prior art, the utility model aims to provide a prefabricated beam-slab type fan foundation which is hoisted on site through a prefabricated beam-slab foundation module, can solve the problems of difficult formwork support, small steel bar spacing, slow construction progress, difficult vibration and compaction of concrete in severe cold regions and difficult guarantee of construction quality in the construction of the traditional beam-slab type fan foundation, and has the advantages of simple structure and convenient installation.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a prefabricated assembly beam slab fan basis, includes fan-shaped precast beam template 4 of polylith, precast beam template 4 includes rib 1, and 1 both sides of rib are the side of symmetric connection bottom plate 3 respectively, and polylith precast beam template 4 encloses to close and forms the ring form, and the ring center is connected with central pillar 2.
And two sides of the rib beam 1 are integrally connected with the connecting bottom plate 3.
The prefabricated beam template 4 which is enclosed to form a circular ring shape and the central column 2 at the center of the circular ring are arranged on the concrete cushion 5.
The precast beam template 4 is reserved with bolt holes and is fixedly connected with the concrete cushion 5 through bolts.
And a reinforcing steel bar is reserved at the inner side end of the precast beam template 4 and is inserted into the central column 2 to be poured into a whole with the central column 2.
The utility model has the beneficial effects that:
1. high structural reliability, prefabrication and construction, and easy quality control
The prefabricated foundation adopts the prefabricated technology of wholesale, compares with cast-in-place foundation, and it is better to pour the environment, easily controls the maintenance problem of bulky concrete, reduces the concrete because of the maintenance is improper, the intensity loss that leads to, promotes the quality of concrete.
2. The concrete consumption is reduced, compared with the conventional gravity type foundation, the concrete consumption is greatly reduced, and the project construction period is shortened.
3. The construction period is shortened, and the construction period can be greatly shortened. After the assembly is finished, the wind turbine tower drum and the iron tower can be directly hoisted, the wind turbine foundation is saved by about 24 days, and the wind turbine foundation is suitable for a grid connection project for a construction period.
4. The application range is wide, the method is suitable for onshore machine type and non-pile foundation, and the problems that the construction quality of the foundation can not be guaranteed in winter and the like can be solved well.
