Abstract
The utility model relates to a spiral ground anchor without a center spindle. The spiral ground anchor without the center spindle is characterized in that a spiral blade without a center spindle, a connecting tube and a connecting plate are included, a notch is formed in one end of the spiral blade without the center spindle, one end of the connecting tube is inserted in the notch, and the other end of the connecting tube is connected and mounted on the connecting plate. The spiral ground anchor without the center spindle is suitable for being used in various soils and capable of lowering using cost.
Description
Technical field
The utility model relates to a kind of earth anchor, relates in particular to a kind of spindle-less screw anchor.
Background technology
At present, the pile of support of buildings mainly contains concrete pile and piling bar, and piling bar is divided into again the stake of H type and steel pipe pile by shape.Concrete pile is applicable to any building, and piling bar then is mainly used in light construction.But concrete pile needs maintenance, long construction period, destruction surface vegetation, and the feature of environmental protection is poor, thus at light construction thing (comprising green house of vegetables, solar bracket etc.) take piling bar as main.Piling bar obtains support force by the frictional force of the vertical direction of its surface and soil, and this support force is smaller, has limited the scope of application of piling bar.Now, a kind of mandrel spiral ground pile that has occurred again, it is welded spiral blade by the external surface at the pyramid type mandrel, increases the contact area with soil, has so just improved the support force of its pile.But its helical blade is easy to distortion when running into harder stratum, has limited the soil scope of using; And this have the mandrel spiral ground pile to need special-purpose pile driver to finish the piling installation, greatly increased use cost.
Summary of the invention
For above problem, the purpose of this utility model is to provide a kind of can adapt to the spindle-less screw anchor that various soil used and can reduce use cost.
Technology contents of the present utility model is: a kind of spindle-less screw anchor, it is characterized in that it comprises spindle-less helical blade, tube connector and junction plate, be provided with a recess at spindle-less helical blade one end, tube connector one end is inserted in the recess, tube connector other end connection junction plate.
The advantage that the utility model has is: patent has adopted following innovative design and method:
(1), adopt without the design of pyramid type mandrel, reduced the welding link of blade and pyramid type mandrel, greatly improved support strength.
(2), all on the central axis of earth anchor, whole helical blade self forms an axle center, so that support force remains on the same axle center of earth anchor, so that support force evenly distributes along the axle center center in the arbitrary cross section of spindle-less helical blade.
3, need not in use special-purpose pile driver and finish the piling installation, reduced use cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of spindle-less screw anchor is characterized in that it comprises spindle-less helical blade 1, tube connector 2 and junction plate 3, is provided with a recess 1.1 at spindle-less helical blade 1 one ends, tube connector 2 one ends are inserted in the recess 1.1, tube connector 2 other end connection junction plates 3.
Claims (1)
1. a spindle-less screw anchor is characterized in that it comprises spindle-less helical blade, tube connector and junction plate, is provided with a recess at spindle-less helical blade one end, and tube connector one end is inserted in the recess, tube connector other end connection junction plate.
