Description

[Detailed description of the device]

[0001]

[Industrial applications]

 As the work performed at the civil engineering work site, there is level setting work for the foundation of buildings, foundations of pillars, road surfaces, slopes, gutters, GL, etc. The present invention relates to a metal-made tensioning pile, which can save labor in this tensioning work, shorten the process, and reduce the cost.

[0002]

[Prior art]

 Conventionally, in the civil engineering construction site, the work of staking is done by cutting the rafters cut to a certain length, shooting the rafter piles that have been made into the opposite ground surface, and then piercing the rafters to set a horizontal level setting machine etc. The same black ink (mark) is set via.

[0003] According to the set black ink, wood such as a furring strip or a skirting board is passed to the opposite side surfaces of the rafter pile, and nailing is performed to set the level between them. It is also practiced to directly hit nails and set water thread.

However, even if a level of water is stretched to set the level, the middle of the stretched thread is affected by slack wind, so that it is not possible to accurately determine the level, and the furrow and the width of the fur It is common to pass wood such as wood to set the level.

[0005] Although the taut work is performed as described above, the rafter pile is made by cutting the rafter tip, and can easily be shot on a frozen ground surface, a gravel-mixed road surface, a rock bed, or the like. However, it is not possible to pierce, and this creates the problem of being forced to make a hole in advance with a golden lever or pickaxe.

[0006]

[Problems to be solved by the device]

 The rafter pile used in the conventional tensioning work cannot be easily shot or pierced on the frozen ground surface, road surface mixed with gravel, bedrock, etc. Wastes extra labor and costs.

As described above, the rafter piles are hard to be shot into the frozen ground surface, gravel-mixed road surface, bedrock, etc., are not easily pierced, and are easily broken, and waste materials are also generated. In this way, construction using a large amount of lumber such as rafters goes against the problems of natural destruction and protection due to forest resource cutting, which is now being called all over the world.

The present invention has developed a metal tensioning pile that can effectively perform tensioning work even on a frozen ground surface, a gravel-mixed road surface, rock, etc., which saves labor and shortens the process. Strikes will be mitigated, and at the same time, some of the problems related to natural destruction and conservation due to deforestation will be resolved.

[0009]

[Means for Solving the Problems]

 In the present invention, instead of the rafter pile, a metal cylindrical columnar body is used as the pile main body, and the point to pierce into the ground is a cone or pyramid spear shape, and the upper part is a hitting part and it is shot by a hammer etc. It was formed into an easy shape.

Since it is a metal tension pile formed in this way, it can be smoothly shot and pierced on frozen ground surfaces, gravel-mixed road surfaces, rocks, etc. Unlike the rafter pile, the metal tension pile enables reuse.

[0011]

[Action]

 The development of the metal-clad piles according to the present invention makes it possible to smoothly carry out pile-pulling work even in civil engineering construction sites that exhibit various adverse conditions such as frozen ground surfaces, gravel-mixed road surfaces, and bedrock. Therefore, the labor can be saved and the process can be shortened, and the cost can be reduced.

[0012] Furthermore, since the pile itself is made of metal, it can be reused after use, and the cone or the pyramid tip and the striking part that are heavily consumed can be replaced at any time, so they are hard to stab and break easily The present invention is also useful for preventing natural destruction due to logging of forest resources, since timber such as rafters used as piles is not used.

【Example】

 The present invention will be described with reference to the drawings. FIG. 1 is a partial front sectional view of the whole assembly of a metal tension pile according to the present invention, FIG. 2 is a partial side sectional view of the same assembly of a metal tension pile, and FIG. 3 is a conventional crossing work. FIG. 4 is a side view of an example, and FIG. 4 is a side view of an example of implementation using a metal-made tension pile according to the present invention.

Conventionally, as shown in FIG. 3, in the work of tensioning civil engineering works, a rafter pile Z is shot and pierced against a ground surface G1 before leveling. On each side of the pierced rafter pile Z, through a horizontal level setting machine, etc., mark the measured back ink G3 at a position slightly higher than the position where it becomes the ground surface G2 after leveling.

When the surveyed back ink G3 is marked on the side surface of the rafter pile, the underlisting of the wood Y such as the furring (in some cases, it may be heaven) is also marked, and it is struck with a nail or the like. The entire listing of the timber Y such as the struck furring strip becomes the reference for the ground surface G2 after leveling.

[0016] Based on the above-mentioned work, level values such as the foundation of the building, the foundations of pillars, road surfaces, slopes, gutters, and GL are set to determine the ground surface G2 after leveling. Since it cannot be easily shot or pierced on the frozen ground surface, road surface mixed with gravel, or rock, and it breaks easily because it is easily broken, it is often done by pre-drilling with a lever or pickaxe.

FIG. 4 shows an embodiment of a claw work using the metal claw pile X according to the present invention. The metal claw pile X is struck and pierced against the ground surface G1 before leveling. When piercing, slide the slide pipe D up and down via a horizontal level setting machine, etc., align it with the survey setting position E2 which is the lower part of the wood fixing tool E, and raise it slightly higher than the position where it becomes the ground surface G2 after leveling. Set the survey value at the position.

When the surveyed value is set, the slide pipe D is fixed by the slide rotation fixing bolt D1, and when the wood Y such as the furring strip is fitted into the wood fixing bracket E, the wood fixing nail Y1 is hammered and fixed. The entire listing of the timber Y such as the struck furring strip becomes the basis for the ground surface G2 after leveling.

Based on this criterion, the margin H between the ground surface after leveling and the back ink is subtracted, and the ground surface G2 after leveling is determined as described above, but the metal tension pile X according to the present invention is used. Since it is used, it can easily hit and stab frozen ground surfaces, gravel-mixed road surfaces, and bedrock.

As can be seen from FIG. 4, since the wood fixing metal fitting E attached to the metal tension pile X rotates in parallel and horizontally to the side surfaces of the slide pipe D and the pile main body A, This is especially effective at construction sites where the level is set diagonally.

The metal tension pile X will be described with reference to FIGS. 1 and 2. The pile main body A has a cylindrical shape, and the tip of the pile that is struck and struck on the ground surface G1 before leveling is formed as the tip B of the cone or the pyramid, and the tip attachment screw portion B1 can be attached and detached for replacement. It

Since the pile main body A is shot and stabbed into the ground surface G1 before leveling with a hammer or the like, a hitting portion C is formed on the upper portion, and the hitting portion mounting screw portion C1 can be attached, removed, and replaced.

The pile body A is provided with a slide pipe D and a wood fixing bracket E. The slide tube D is fixed by sliding to the upper part and the lower part of the cylinder showing the pile body A, so that it can be rotated 360 ° around the cylinder and fixed at any position.

The wood fixing bracket E is formed integrally with the slide pipe D, and has a function of rotating in the direction of arrow E3, which is parallel to the side face of the slide pipe D and the pile main body A and which indicates the rotation direction of the horizontal turntable. It has a U shape when viewed from the side.

In accordance with the survey setting position E2, which is the lower part of the wood fixing bracket E, the survey value is set to a position slightly higher than the position where the ground surface G2 after leveling is set, and the U-shaped wood fixing bracket is set. When timber Y such as a furring strip is fitted into E, the timber is nailed and fixed with timber fixing nails Y1, and the entire listing of timber Y such as the furnished furring becomes the ground surface G2 after leveling. Therefore, the ground surface G2 after leveling is subtracted from the ground surface G2 after leveling and the return ink from the entire listing of the timber Y such as furring strips, and the ground surface G2 after leveling is set.

[Effect of device]

 The present invention uses metal stakes for the staking work, so that the stakes can be used even in civil engineering construction sites that exhibit various adverse conditions such as frozen ground surfaces, gravel-mixed road surfaces, and bedrock. Since it is possible to carry out the shooting work smoothly, it is possible to save labor and shorten the process, thus reducing the cost.

Further, unlike the rafter pile, the metal tension pile can be reused. Furthermore, since rafter piles are not used, it will have a better effect on problems related to natural destruction and protection due to deforestation of forest resources.
