The existing common fan foundation mainly comprises a circular expansion foundation and a beam slab foundation, wherein the upper part of the circular expansion foundation is a cylinder, the lower part of the circular expansion foundation is a round table body, and the circular expansion foundation is poured by reinforced concrete.
The center of beam slab formula basis is the cylinder, and the periphery is the circular ring roof beam that highly is less than this cylinder, is equipped with a plurality of beam slabs of evenly arranging between circular ring roof beam and this cylinder, and beam slab formula basis has reduced reinforced concrete's use amount, nevertheless owing to set up multichannel concrete beam slab for the inside reinforcing bar of basis arranges unusually intensively, and the reinforcing bar quantity is big and the concrete is difficult for pouring, and construction quality can not guarantee.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a casing fan basis, intensity that can full play reinforced concrete material saves reinforced concrete's quantity.
In order to achieve the purpose, the utility model is realized by adopting the following technical scheme:
the utility model provides a casing fan foundation, the inverted cone shell including the inner circle, the top surface girth, the just circular cone shell and the bottom surface girth of outer lane, the inverted cone shell of inner circle is located fan foundation's center, the just circular cone shell of outer lane passes through the inverted cone shell fixed connection of top surface girth and inner circle, the just circular cone shell and the bottom surface girth fixed connection of outer lane, the top surface girth upwards is connected with fan tower cylinder's flange, the elevation of each point reduces gradually along the direction from top surface girth to bottom surface girth on the just circular cone shell of outer lane, and the zero point of elevation is place ground, the orthographic projection of the inverted cone shell summit of inner circle and the orthographic projection of the just circular cone shell summit of outer lane coincide completely.
Furthermore, the elevation of the vertex of the inverted conical shell of the inner ring is lower than that of the top ring beam.
Furthermore, a foundation ring or an anchor bolt cage is embedded in the top ring beam, and the top ring beam is connected with a connecting flange of the fan tower cylinder through the foundation ring or the anchor bolt cage.
Furthermore, the elevation of the top ring beam is 300mm higher than the ground of the site.
Furthermore, the inverted conical shell of the inner ring and the regular conical shell of the outer ring are both arranged below the ground of a field.
Furthermore, the bottom ring beam is arranged below the ground of the field.
Compared with the prior art, the utility model discloses the beneficial effect who reaches includes at least:
under the action of fan load, the inverted conical shell of the inner ring bears pressure, and the right conical shell of the outer ring and the bottom ring beam bear tensile stress, so that the strength of reinforced concrete materials can be fully exerted, and the using amount of reinforced concrete is saved.
Drawings
Fig. 1 is a top view of a housing fan base according to an embodiment of the present invention;
fig. 2 is a front view of a housing fan base provided in an embodiment of the present invention;
in the figure: 1. an inverted conical shell of the inner ring; 2. a top ring beam; 3. a right circular conical shell of the outer ring; 4. the bottom surface is a ring beam.
Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
It should be noted that, in the description of the present invention, the terms "upper" and "lower" indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, and the terms "inner" and "outer" respectively refer to the directions toward or away from the geometric center of a specific component, which are only for convenience of description of the present invention and do not require that the present invention must be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 to 2, the embodiment of the utility model provides a pair of casing fan foundation, including the inverted cone shell 1 of inner circle, top surface gird 2, the positive cone shell 3 and the bottom surface gird 4 of outer lane, the inverted cone shell 1 of inner circle is located the center on fan foundation, the positive cone shell 3 of outer lane is through top surface gird 2 and the inverted cone shell 1 fixed connection of inner circle, the positive cone shell 3 and the bottom surface gird 4 fixed connection of outer lane, pre-buried foundation ring or crab-bolt cage in the top surface gird 2, top surface gird 2 upwards is connected through foundation ring or crab-bolt cage and the flange of fan tower section of thick bamboo, the elevation on the inverted cone shell 1 summit of inner circle is lower than the elevation of top surface gird 2, the elevation of top surface gird 2 exceeds place ground 300mm, bottom surface gird 4, the inverted cone shell 1 of inner circle and the positive cone shell 3 of outer lane all arrange the below the place in. The elevation of each point on the right circular cone shell 3 of the outer ring is gradually reduced along the direction from the top ring beam 2 to the bottom ring beam 4, the zero point of the elevation is the ground surface, and the orthographic projection of the vertex of the inverted circular cone shell 1 of the inner ring is completely overlapped with the orthographic projection of the vertex of the right circular cone shell 3 of the outer ring.
The shell foundation is a foundation form capable of giving full play to the strength of materials, has sufficient strength, rigidity and stability, and has the advantages of small settlement, material saving and low manufacturing cost compared with an entity foundation, and the technical and economic effects are obvious.
Under the effect of fan load, the reverse conical shell 1 of the inner circle in the embodiment of the utility model bears pressure, and the normal conical shell 3 and the bottom ring beam 4 of the outer circle bear tensile stress, thereby the intensity of reinforced concrete material can be fully exerted, and the dosage of reinforced concrete is saved.
