The utility model content
Because the above-mentioned defective of prior art, technical problem to be solved in the utility model provides that a kind of cost is low, the batter post formula iron tower foundation of good stability.
For achieving the above object, the utility model provides a kind of batter post formula iron tower foundation, comprise concrete sole plate, described sole plate has a bottom surface and an end face, be set with anchoring piece in the described sole plate, the described relatively bottom surface of described anchoring piece is obliquely installed, and the angle of inclination of described anchoring piece is roughly the same or identical with the angle of inclination of iron tower column foot.
Preferably, described anchoring piece by the welding of a plurality of angle steel make and form can ccontaining described iron tower column foot hollow hub.
Preferably, the whole or bottom of described anchoring piece is arranged in the described sole plate.
Preferably, also be provided with the arrangement of reinforcement that improves described sole plate intensity in the described concrete sole plate.
Batter post formula iron tower foundation of the present utility model has adopted the anchoring piece that is obliquely installed.After batter post formula iron tower foundation is long owing to service time, between concrete and steelwork, be formed with the slit because of rising-heat contracting-cold.Because anchoring piece is to tilt to be inserted in the concrete sole plate in the utility model, so the slit that forms between the sole plate of the anchoring piece of steel and concrete system also tilts.The body of the tower deadweight is decomposed into a vertical stress component and a horizontal component after transmitting along the column foot that tilts.This vertical stress component makes iron tower integral body have power to lower slider, thereby iron tower is when the generation of the slit of above-mentioned inclination, can do slight moving down (this minute movement can be ignored the accuracy of tower body position), fill up this slit, thereby make iron tower integral body have good stable.
Structure of the present utility model makes iron tower foundation whole stressed reasonable, and good stability has anti-overturning preferably.When making iron tower foundation obtain good stability, because it is stressed reasonable, given full play to concrete resistance to pressure, the quantity of the arrangement of reinforcement that is provided with on the iron tower foundation also can reduce significantly, therefore the utility model generally can reduce construction cost significantly than concrete and the amount of reinforcement (deciding on geological condition) about straight column type basis saving 10%-40%.
Be described further below with reference to the technique effect of accompanying drawing, to understand the purpose of this utility model, feature and effect fully design of the present utility model, concrete structure and generation.
Description of drawings

Fig. 3 is an A-A cross-sectional schematic among Fig. 2;
Fig. 4 is a B-B cross-sectional schematic among Fig. 2.
The specific embodiment
As shown in Figure 2, the utility model is applied in the specific embodiment in the soft foundation.Batter post formula iron tower foundation 1 comprises the sole plate 11 that concrete makes, and as shown in Figure 4, sole plate 11 has an end face, one bottom surface, be divided into big end down integrally formed two-layerly, be set with anchoring piece 12 in sole plate 11, anchoring piece 12 is used for fixedlying connected with the iron tower column foot.
Be illustrated in figure 3 as the shape of cross section of anchoring piece 12 in the present embodiment, be welded, have the jack of a hollow, to allow the iron tower column foot plug by angle steel.
In the present embodiment, the Lower Half of anchoring piece 12 is arranged in the sole plate 11, and the first half is arranged in the basic pilum.In other embodiments, anchoring piece 12 can integral body be arranged in the sole plate 11 and only reserves jack.
Special character of the present utility model is that the bottom surface of anchoring piece 12 relative sole plates 11 is for being obliquely installed, and the angle of inclination of anchoring piece 12 is identical with the angle of inclination of iron tower column foot.
For improving the bonding strength of sole plate 11 and anchoring piece 12, in sole plate 11, also be provided with arrangement of reinforcement 13.The quantity of arrangement of reinforcement 13 depends primarily on the size of body of the tower load, and load is big more, and arrangement of reinforcement 13 quantity are many more; Load is more little, and arrangement of reinforcement 13 quantity can be few more.
After the body of the tower of batter post formula iron tower inserted anchoring piece 12 by column foot master material, batter post formula iron tower foundation 1 mainly stressed was that sole plate 11 is directly passed in the body of the tower deadweight, and the top of anchoring piece 12 only acts on the very little horizontal component of body of the tower deadweight.Therefore, the moment of flexure that acts on the whole basic pilum is very little, thereby not only improved the stability of batter post formula iron tower foundation 1 overturning or slip resistance analysis greatly, and because the moment of flexure that acts on the anchoring piece 12 is very little, the cross-sectional area of anchoring piece 12 can determine that the arrangement of reinforcement of general basic pilum also can be just passable by the structure configuration by the structure minimum dimension.Because reducing of the clean reagency of ground makes the moment of flexure that acts on the sole plate 11 reduce, thereby the concrete of sole plate 11 and quantity of reinforcement have also reduced many accordingly.
Batter post formula iron tower foundation of the present utility model owing to adopted the anchoring piece that is obliquely installed, makes iron tower foundation whole stressed reasonable, good stability.When making iron tower foundation obtain good stability, because it is stressed reasonable, the quantity of the arrangement of reinforcement that is provided with on the iron tower foundation also can reduce significantly, and therefore the utility model generally can reduce construction cost significantly than concrete and the amount of reinforcement about straight column type basis saving 10%-40%.
