Abstract

[purpose]

It is easy to assemble on site and carry out total load test with soil and gravel which is easy to get anywhere.After loading test, it is convenient to get off the pile, empty the soil and then dismantle it to move to another place or transport it to the storage place. To provide a load box for the vertical load test.

[Configuration]

It consists of the front plate (1) and the back plate (2) and the left and right side plates (3) and the bottom plate (4) attached with a plurality of clasps (5) inside the sides that meet each other, assembled in each direction Insert the clamp (6) between the front plate (1) and the back plate (2) and the side plate (3) and the bottom plate (4) by the clamps (6) and connect the brackets exposed to the opposite side of the clamps (5). The nut (7) is fastened to both ends of (6) to be assembled into a box body so that the weight can be used as a dead load.

The present invention relates to a load box for the vertical load test of piles, which is conducted as part of the method of grasping the behavior of the foundation piles. Specifically, the static vertical load test is carried out by containing soil, gravel, etc. After loading test, it is related to load box for vertical load test of pile, which is convenient for emptying the soil and then dismantling it and moving it to another place or transporting it to a storage place.

Vertical load tests of piles require large dead weight loads that exceed the tip bearing capacity and the principal surface friction of the piles. Heavy materials are used for large concrete blocks, construction materials such as reinforcement bundles around the site or unbreakable cement bags.

Among such heavy materials, construction materials such as concrete blocks, rebar bundles, and cement bags are inconvenient because the vertical load tests are usually possible only when two or four times the pile design load is sufficient.

If it is difficult to procure the dead weight in all conditions of the construction site, it is inevitable to adopt the vertical load test method using the test cost and the reaction force of the long anchor pile.

Therefore, the purpose of the present design is to load the soil, gravel, etc., which can be easily obtained at any site, and can carry out vertical load test quickly and inexpensively, and can be dismantled and transported and stored in small volume for pile vertical load test. To provide a load box.

This load box is composed of sheets of face plates in each face direction. Each faceplate is transported to the site, and the bracket is flowered and the nut is tightened with a nut to form a box. Also, the nut is removed and the bracket is disassembled into each faceplate. When the plate is stacked and stacked in the direction of the plane for long and short distances, the loading volume is small, and it takes up less space by stacking it at the place of storage.

Hereinafter, the present invention will be described in detail according to the accompanying drawings prepared based on the preferred embodiment.

As shown in Figure 1, the load box of the present invention is woven into the front plate (1) and the back plate (2), the left and right side plate (3) and the bottom plate (4). A plurality of clasps 5 are attached to just inside of all sides that meet other face plates on the inner surface of each face plate. The clasp 5 may be attached by riveting or bolt-nut fastening, but a welding attachment method is preferable to eliminate the protrusion to reduce the stacking height and make it easier to use.

Combining each of the face plate material in each direction has the same aspect as that of FIG. 2. In the assembled load box, the clamps 6 as shown in FIG. 3 are mobilized to fix the face plates that are in contact with each other in each direction. These brackets (6) are made of front plate (1) and both side plates (3), back plate (2) and both side plates (3), bottom plate (4) and front plate (1) and back plate (2) Both sides of the side plate (3) are connected to each other at right angles, and fixed to each other, which can be simultaneously hooked into the face plate side clasps (5) of different directions to be connected to each other, and must also have sufficient strength, as well as to be fixed on site do. All these conditions are met with U bolts of considerable thickness. After inserting the clamp 6 into the collar 5, tighten the nut 7 to the lead portion.

4 is an enlarged cross section taken along line B-B in FIG. In the front plate 1 and the back plate 2, a hook 9 is attached to the upper side of the center of gravity on a line passing vertically through the center of the width. It is easy to move the rope of heavy equipment such as a crane or tower crane to this hanger (9), move it to another place, put it on the head of the test pile, or lower it from the head of the test pile after the test. In that figure, the recess 8 is an optional element that may be formed to avoid the hook 9 from protruding from the outside of the front plate 1 and the back plate 2.

FIG. 5 is an example in which the load box (a) of FIG. 2 is prepared in a state in which the vertical load test is possible on the pile to be tested. The pile cap 11 is placed on the test pile 10 and the measuring device is placed on the pile cap 11. And universal beams are installed one after the other, and then hydraulic pressure is applied to a load box (a) filled with soil, rock, gravel, or water bag on the beam beam, and hydraulic pressure is applied to the test pile (10). You can go in.

As described above, the vertical load test box of the pile of the subject innovation is convenient to carry out the vertical load test quickly and easily by using soil, rock, gravel, and water, which are easy to obtain in the field, and it is convenient to disassemble each face plate. It is provided as a lamination convenience at the time of loading or in the place of loading, as well as being small in loading volume, which is convenient.
