Description

[Detailed description of the invention] This invention relates to a support stand for pile erection, and in particular, a hanging beam is supported by at least three vertically expandable jacks, and the hanging beam has at least three The posture of the hanging beam on which the piles are suspended is controlled by connecting the strips of books, and the vertical accuracy of the piles can be easily adjusted by moving the strips up and down and erecting piles while adding piles. You will be able to submit it to

Conventional support stands for pile erection have all adopted means for fixedly supporting the piles, such as supporting the piles with brackets and supporting the brackets with vertical jacks and beams.

However, according to this method, the support is fixed, so in order to achieve vertical accuracy while supported, another horizontal jack must be installed, which requires the work of pushing the pile laterally and the work required to do so. Accordingly, it is necessary to release the vertical jack and to support it again, which not only makes the work unnecessarily complicated, but also leaves insufficient accuracy.

In particular, it was troublesome to obtain the vertical accuracy of the piles when building a structure by adding piles.

Therefore, this invention was provided to eliminate such drawbacks of the conventional method, and its purpose is to improve the vertical accuracy of piles,
In particular, the purpose is to easily improve the vertical accuracy of piles when erecting piles by adding parts, and the purpose is to improve the vertical accuracy. The purpose is to provide a low support base.

That is, this invention, as in the illustrated embodiment, has a suspension beam in which a turret 9 for holding the pile 1' added from above is disposed at the upper part, and a hanging beam configured to pass the pile 1 added below in the center. 2, at least three strips 3 whose lower ends are connected to the lower stake 1 for hanging it are connected so that the strips 3 are arranged around the lower stake 1; In addition, the hanging beam 2 is supported by at least three jacks 4 that extend and contract in the vertical direction independently, at positions where the jacks 4 surround the pile 1 located below. Regarding the support stand.

Next, this invention will be explained according to illustrated embodiments.

A suspension beam 2 is supported by jacks 4 on a base 5 made of shaped steel assembled in the shape of a flat parallel girder.

Although the hanging beam 2 is made of two parallel steel sections in this embodiment, it is not limited to this embodiment as long as it has a structure in which the stake 1 is vertically passed through the center thereof.

Each jack 4 can be operated independently,
They are arranged to expand and contract in the vertical direction and are placed at each of the four corners of the hanging beam 2, for a total of four pieces.

The four corners of the suspension beam 2 here mean the respective ends of the two section steels that constitute the beam 2.

If the suspension beam 2 does not have the shape as in this embodiment, three jacks 4 are sufficient.

However, this does not mean that five or more jacks 4 are excluded.

Four pairs of guide brackets 6 for guiding the elevation of the beam 2 are fixed to the base 5, and the beam 2 and the jack 4 are interposed between the opposing surfaces of the guide brackets 6 of each village.

Four strips 3 are connected to the suspension beam 2, the lower ends of which are connected to the pile 1 for hanging.

The strip 3 is made of wire rope, and four of the strips 3 are arranged around the pile 1 so as to surround the pile 1.

Although four strips 3 are used here, at least three strips are sufficient.

Further, it may be five or more, but a large number, such as 10, would complicate the work and is therefore not suitable.

A hanging bracket 7 is fixed to the pile 1 in advance, and the strip 3
A metal fitting 8 fixed to the lower end is connected with a pin to the hanging bracket 7 to connect the strip 3 and the stake 1.

The four strips 3 are arranged so that the distance between them widens upward, and the hanging bracket 7 is fixed to the pile 1 with an inclination in the same direction as the strips 3.

Reference numeral 9 denotes a tower for erecting the pile 1, and a support base for erecting the pile according to this invention is arranged at the bottom of the turret.

While the pile erecting support supports and suspends the lower pile 1 from its upper part, the turret 9 supports the upper pile 1' which is continuous with the lower pile 1.

Moreover, 10 is an excavated hole for erecting the pile 1.

Thus, the pile 1 suspended by the strips 3 moves a part of the suspension beam 2 up and down by operating the jack 4 as appropriate, so that some of the four strips 3 are moved up and down. By moving up and down, the inclination is corrected and vertical accuracy is achieved.

Therefore, according to this, the vertical accuracy of the pile 1 can be achieved extremely easily by only operating a part of the jack 4.

When the upper pile 1' is added to the lower pile 1, the upper pile 1' is slightly lifted by a crane or winch that is lifting the upper pile 1', and the lower pile 1 is also lifted at the same time. Therefore, it is only necessary to release the tension on the strip 3 and remove the strip 3 from the pile 1 below.

Next, both piles 1 and 1' are suspended into the excavated hole 10, and the lower pile 1' is connected to the strip 3 in the same manner as described above, thereby automatically ensuring vertical accuracy.

At this time, if the continuous two-way joints 1, 1 are tilted due to the center of gravity of the upper pile 1' being shifted, vertical accuracy can be achieved only by the above-mentioned jacking operation.

Therefore, according to this invention, the jacks that support the piles with high precision, as in the past, are released, and then the piles are suspended together with the added piles above, which are then supported again by the jacks, and the vertical accuracy is further improved. Since there is no need for the complicated operation of estimating the height, high vertical accuracy can be achieved with a simple operation.

Moreover, since the structure is extremely simple, such as eliminating the need for horizontal jacks, the cost is low and it is convenient to move and handle.
