The number of described middle annulus beam can be individual arbitrarily, as more than two.
Linking beam is provided with between described two adjacent middle annulus beams, linking beam is in radiation beam, middle annulus beam and the closed interval of encircling a city between annulus beam in another, and linking beam one end is connected to a point of intersection of radiation beam and middle annulus beam, the linking beam other end is connected to radiation beam and a point of intersection of annulus beam in another, and described two intersection points are non-conterminous.
The utility model is reasonable in design, stressed clearly, good stability, integral rigidity are large, command displacement ability is strong, soil excavation is convenient, greatly can save the duration, under the prerequisite ensureing deep pit monitor, improves economic and social profit.
The beneficial effects of the utility model are: brace summer flexible arrangement, according to the demand such as support stiffness, soil excavation reasonable Arrangement annulus beam, can comprise the diameter of annulus beam, cross section and number of channels etc.; Resistance to overturning is good, rigidity is large, effectively can control the displacement of foundation pit enclosure structure, and the construction of structures of protection foundation ditch periphery, reduces the impact on surrounding enviroment to greatest extent; Shoveling speed is fast, the saving duration, and for large-scale excavation, use many annulus beam combined support structure, can ensure the larger foundation pit construction scope of operation, soil excavation is convenient, greatly saves the duration, the remarkable in economical benefits indirectly brought.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See Fig. 1, the utility model comprises inner circle ring beam 2, cylindrical ring beam 4, middle annulus beam 3, radiation beam 5 and encloses purlin 1, described inner circle ring beam 2, cylindrical ring beam 4 and middle annulus beam 3 are positioned at the same center of circle, radiation beam 5 is at inner circle ring beam 2 and enclose between purlin 1, and radiation beam 5 is by inner circle ring beam 2, cylindrical ring beam 4, middle annulus beam 3 and enclose purlin 1 and link into an integrated entity.
Linking beam 6 is provided with between inner circle ring beam 2 and middle annulus beam 3, linking beam 6 radiation beam 5, between inner circle ring beam 2 and middle annulus beam 3 besieged city closed interval in, and linking beam 6 one end is connected to a point of intersection of radiation beam 5 and inner circle ring beam 2, linking beam 6 other end is connected to a point of intersection of radiation beam 5 and middle annulus beam 3, described two intersection points non-conterminous (namely described closed interval is squarish, and linking beam is positioned on the diagonal of squarish).
Linking beam 6 is provided with between middle annulus beam 3 and cylindrical ring beam 4, linking beam 6 radiation beam 5, between cylindrical ring beam 4 and middle annulus beam 3 besieged city closed interval in, and linking beam 6 one end is connected to a point of intersection of radiation beam 5 and cylindrical ring beam 4, linking beam 6 other end is connected to a point of intersection of radiation beam 5 and middle annulus beam 3, and described two intersection points are non-conterminous.
