Abstract

The present invention seeks to provide a non-embedded shovel installation anchor that can withstand loads and transverse pressures with a strong bearing force in a short time, and is based on a short steel cross section whose cross section is cross (+). An upward barb is formed on the wing formed along the longitudinal direction, and the upper end of the base material includes an inner end of each wing, and concave in the middle, and a steel plate head is attached to the bottom thereof. Achieve this with a buried anchor installation anchor with a donut flange for fixing the bottom of the strut.

Description

Non-embedded Shovel Pile {Pile}

The present invention relates to a buried pile installation file.

Non-embedded struts are long objects that cannot be built directly on the ground, such as the main tower (column) of a wind power generator, and are struts that must be erected by flange welding or flange fastening.

Commonly used files include PC file and steel pipe file. These piles are generally long and weighty. The construction or type of non-embedded shoring piles on the ground or on the seabed or the sea floor may be carried out depending on the conditions of the ground or by mobilizing a rider or auger and navigator together.

The problem of using a long file as a non-embedded prop file is very inefficient due to the long construction or type time per file.

For example, it is uneconomical that heavy machinery occupies a large portion of the anchor installation ratio, for example, to enter or type a ready-made PC file or a steel pipe file of a standard or the like, or mobilize a ride.

On the other hand, when the load on the non-embedded shoreline is small and the pile does not need to be deeply buried in the ground, a shorter file than a conventional PC file or steel pipe file may be effective.

However, short piles have small frictional force, so they have a limited bearing capacity when they are typed on the ground, and the posture may be unbalanced due to inadvertent lateral pressure, such as strong winds, which are difficult to measure directionality.

Therefore, the present invention is to provide a non-embedded strut installation pile that can withstand load and lateral pressure with a strong bearing force in a short time.

This problem is based on a short steel cross-section cross (+) of the base material, the upper barb formed on the wing formed along the longitudinal direction in the base material, the upper end of the base material includes the inner end of each wing It can be achieved with a non-embedded strut installation pile with a concave cut in the middle and a steel head at its bottom, and a donut-type flange for fixing the bottom of the unfilled strut at the top of the wing.

Particularly suitable for piles of small ground structures such as small wind turbines, small wind compressors, traffic lights, street lights, etc., which are constantly loaded after construction and are less affected by wind pressure. It is shorter and lighter than conventional PC or steel pipe pile, so it is easy to type on the ground, and the price is low, and the barb given to each wing improves bearing capacity, and even though the type length is short, it exhibits an anchor force that is not as good as that of ordinary long PC files or steel pipe piles. Once you get stuck in the ground, it doesn't bounce back, so it's perfect for anchor piles.

In Fig. 1, the base material 10 for non-embedded props proposed by the present invention is a steel having a cross section. The reason for choosing the cross-type steel as the base material is that it is easy to procure as a commercially available steel, and it has a structure that is easy to attach the flange for the installation of the head and the non-embedded strut. This is because it has the strength to show enough friction ability.

In Figure 2, the tip of the base material 10 is processed by the needle 12 to increase the typeability to the ground. Each blade 14 is provided with a barb 16 at a predetermined pitch. These barbs 16 do not oscillate and do not bounce back against external forces such as vibrations acting in the reverse type direction after anchors are embedded in the ground, strong winds or ground reflection winds, and impacts that flow through the ground, and are not supported by the wings 14. This prevents the file from shaking and shaking.

The portion where the wings 14 intersect at the upper end of the base material 10 is cut to the same width and height based on the center of the intersection to be the acupuncture seat 18.

In FIG. 3, the head plate 20 is attached to the bottom of the head restraint 18. The throttle plate 20 is a thick steel plate having durable strength suitable for rudder piercing by focusing the driving force of the helm when the anchor is typed so that it can be effectively typed without damaging other parts. Place it flat on the bottom and fix it by welding.

The donut-shaped flange 24 is attached to the top of the wing 14 of the base material 10. The donut-shaped flange 24 is for preventing the deformation of the upper end of the wing 14, and the hole 26 drilled in the abdomen is equal to the width of the head plate 20 so that the hammer of the rider can freely move in and out. do. The donut-type flange 24 is suitable for abutting or fastening a flange attached to the lower end of the non-embedded shore, and also serves to reinforce the upper end of the wing 14 whose strength is lowered as the anti-head seat 18 is formed. do.

As shown in Fig. 4, the pile (a) of the present invention is erected vertically on the ground where the non-embedded strut is to be installed, and then the hammer (c) of the cruiser (b) is inserted into the acupuncture seat (18) through the hole (26). The hammer engine is operated with the lower end touching the head plate 20 to drive to a predetermined depth. The type pile (a) cannot swing back, forth, left, and right in the ground due to the resistive force of the blades 14, and the pulled by the barb 16 is also prevented together. Therefore, even though the anchor is a long anchor as long as the anchor will exhibit enough strength.

After this type of pile (a), and withdrawal of the ride, as shown in FIG. 5, the flange 32 attached to the lower end of the non-embedded strut 30 is placed on the flange 24 to hold the center and weld or bolt-nut. Install in order to tighten.
