Description

  The present invention relates to a law tensioning apparatus and a law tensioning method.

  FIGS. 9 (a) and 9 (b) to 12 show an example of a conventional method of tensioning using a wooden square or plate material and a method of tensioning. In each figure, symbol A is the shoulder, B is the slope, C is the slope, D is earth and sand removed by construction, δ is the slope of the slope, and h is the height from the slope B to the shoulder A. In the following description, the ratio of h: δ × h is expressed as gradient vertical distance: gradient horizontal distance, and the normal gradient 1: δ indicates that the distance moves horizontally by the distance δm per 1 m height. With the vertical line passing through the boundary, the butt B side is defined as the front, and the counter butt B side is defined as the rear.

  As shown in FIG. 9A, first, the temporary tack 1 is driven vertically onto the vertical line of the shoulder A. Let ΔH be the height from the shoulder A to the temporary anchor.

  Next, as shown in FIG. 9B, the first pile 2 is driven perpendicularly to the ground with a distance of δ × H or more rearward from the shoulder A. The value of H is appropriately determined from the positional relationship between the legal gradient 1: δ and the installation plan of the legal order.

  As shown in FIG. 10 (a), the lateral nail 2a is struck at a position on the side face of the first pile 2 where the height from the shoulder A is H, and further, as shown in FIG. 10 (b). Secondly, the second pile 3 is driven vertically behind the first pile 2.

  As shown in FIG. 11 (a), the horizontal penetrating plate 4 is placed in a horizontal posture and the upper end of the horizontal penetrating plate 4 matches the height of the horizontal nail 2a. Fix it. That is, a line with a height H from the shoulder A is represented by the upper end of the transverse plate 4.

  Next, the nail 4a is driven from the upper side to the intersection of the vertical line from the point δ × H and the transverse plate 4, that is, the position where the slope C and the upper end of the transverse plate 4 intersect, Bend to. The nail 4a is called a hook nail.

  As shown in FIG. 11 (b), the slanting plate 5 is adjusted so that the lower end thereof is in contact with the hook nail 4a and the slant so as to be along the slope C is slanted. Nail the first or second pile 2 or 3 with a nail.

  A series of construction operations shown in FIGS. 9A and 9B to FIGS. 11A and 11B are repeatedly performed at predetermined intervals along the envelope of the shoulder A. Thereafter, as guided by the diagonal plate 5, earth and sand are removed using a heavy machine or the like to form a slope C.

  FIG. 12 shows a shoulder A, a slope B, and a slope C after the earth and sand have been removed using a heavy machine or the like. When embankment is required at the time of construction, the first and second piles 2 and 3 may be driven forward from the temporary anchor.

  In the above-described example, the case where the false anchor 1 is driven vertically onto the vertical line of the shoulder A has been described. However, if the relative position with respect to the shoulder A can be grasped, the dummy 1 is driven onto the vertical line of the shoulder A. It is not necessary, and it may be driven into a position near the vertical line of the shoulder A.

  Usually, in the method of tension, the diagonal plate is the reference for the gradient, so the diagonal plate needs to be perfectly straight and uniform in thickness. However, in the conventional law tensioning apparatus using wood, there are many products with processing errors, so it has been necessary to perform a process such as cutting with a saw on the spot to surpass the urgent place.

  In addition, in order to install an accurate law tightening, it is necessary to perform patient work and calculations patiently using skilled surveying techniques, and not only was the work effort spent on this difficult. The part that relied on the intuition of the workers was also large.

  In addition, if the pile driven into the ground is tilted diagonally, apply a stone or the like to the base and push it in or correct it, or strike it again, or insert a blank plate between the pile and the tension It was necessary to adjust with.

  Since these wooden squares and plates are consumables and are discarded once they are used, there has been a demand for a reusable law tensioning device from an economical point of view. In addition, when carrying a large number of wooden squares and plate materials to the site, the weight is large, so there is also a problem that the carrying work requires labor.

  In view of such problems, Patent Document 1 aims to provide a tensioning device that can easily adjust the length and angle, reduce time and cost, and save wood resources. A stringing device has been proposed.

  The tensioning device has a horizontal member in which a plurality of rectangular plate members are stacked in the thickness direction, and these plate members are configured to have the same width and are slidable in the longitudinal direction with respect to each other via rails. .

  According to the tensioning device, the plurality of plate members constituting the horizontal member can slide with each other, so that the length can be freely adjusted, and it is not necessary to cut to the required length every time construction is performed, so that it can be used repeatedly. Can reduce wood consumption and preparation burden. In addition, since they are overlapped in the horizontal direction perpendicular to the slide direction and have the same width in the vertical direction, there is no difference in height between the both end portions and the intermediate portion on either the upper side or the lower side of the horizontal member.

  Moreover, it has a clamp member which fixes a horizontal member to a to-be-fixed object, This clamp member is slidable in the longitudinal direction of the arm part and the clamp part connected to one end of this arm part so that rotation is possible. And a fixed portion connected thereto. If comprised in this way, a tension can be installed, adjusting finely mechanically, without re-staking a pile.

  Further, Patent Document 2 discloses a tension plate configured such that elongated holes are formed in a plurality of tension plates and the tension plates are connected to each other so as to be rotatable with a wing nut, or the length is adjustable. ing.

  However, an example of adjusting the angle of the horizontal member via the clamp member when performing the method of tensioning using the tensioning device disclosed in Patent Document 1 is shown. No specific installation work is disclosed regarding whether to adjust the angle of the clamp member corresponding to the angle of the surface.

  For example, even if the angle between the pile and the horizontal member is adjusted via the clamp member, it is unclear how it must be reused in order to function as a transverse plate or a diagonal plate, realizing efficient work Therefore, there was room for further improvement.

  In addition, in the tension plate described in Patent Document 2, the work of assembling each tension plate is reduced by connecting the tension plates with a wing nut, but with respect to the transverse plate fixed in a horizontal posture. Therefore, even if the diagonal plate is rotated around the wing nut, it is essentially impossible to align the longitudinal side surface of the diagonal plate with the slope, and at that time, the rotational axis is long. There is a possibility that the position may be displaced along the hole, and it is difficult to follow the exact slope.

  In addition, in any configuration, it is necessary to use a separate slope ruler such as a slant in order to adjust the diagonal plate to a predetermined legal gradient, and there is a problem that a complicated operation is required.

  Further, the indicator 61 that indicates the scale line of the transverse plate scale portion 41 and the indicator 61 are guided so as to be movable along the transverse plate 4 so as to indicate the reference position CP of the scale line of the transverse plate scale portion 41. A transverse plate guide member configured to include an instruction portion guide mechanism 63 and a transverse plate guide member support mechanism that supports (axially supports) the transverse plate 4 so as to be movable along the transverse plate vertical guide mechanism 21. . The transverse plate guide member support mechanism is constituted by a fixture 7e.

In the following, another embodiment of the law tensioning apparatus according to the present invention will be described.
In the embodiment described above, an example in which each member is made of a resin material has been described. However, the type is not particularly limited, and a general-purpose resin material such as polypropylene (PP) can be used. In this case, in order to increase the rigidity of each of the horizontal through plate 4, the oblique through plate 5, and the pile members 2 and 3, a reinforcing portion such as a rib may be provided on the surface opposite to the mutual contact surface. In particular, the pile members 2 and 3 are preferably formed in a 'L' shape so that the pile members 2 and 3 are not easily bent by the impact of a hammer when driven into the ground.

  Moreover, each member may be comprised with lightweight members other than the resin material. For example, you may be comprised with light metals, such as aluminum or aluminum alloy. The light metal generally means a metal having a specific gravity of 4 to 5 or less, and titanium or the like can be used in addition to aluminum.

  In the above-described embodiment, a columnar pin having a rectangular cross section is used as the rotation restricting portion 48 that restricts the oblique penetration plate to rotate about the reference point in a state where it is in contact with one longitudinal side edge of the oblique penetration plate. The configuration in which any one corner where the four peripheral walls of the columnar body intersect is located at the reference point BP has been described. What is necessary is just a pin shape provided with the corner | angular part which makes point contact with a side edge.

  Further, in the law tightening apparatus according to the present invention, the rotation restricting portion 48 is not an essential component, and the rotation restricting portion 48 may not be provided. In that case, the diagonal plate 5 is rotated along the arcuate slit constituting the diagonal plate support mechanism 46 so that the longitudinal side edge 52 of the diagonal plate 5 is along the target gradient scale line 45. And it may be adjusted while moving.

  In the embodiment described above, when the transverse plate guide member 6 is provided and the transverse plate 4 is moved along the transverse plate lateral guide mechanisms 42 and 43, the scale line designated by the instruction unit 61 is used as a reference. Although the configuration that can accurately read the necessary distance has been described, a legal tensioning device that does not include the transverse plate guide member 6 may be used. In such a case, the operator may move it while viewing the scale of the transverse plate scale portion 41a while considering the movement distance.

  Further, in the above-described example, the example in which the scale is engraved on the left and right with the center portion as the reference position CP so that the transverse plate scale portion 41 is left-right symmetric is described. However, the scale is symmetric about the reference position CP. It does not need to be engraved, and the scale may be engraved with reference to either left or right end. Also in this case, the transverse plate 4 may be moved by the target gradient horizontal distance with reference to the scale line instructed by the instruction unit 61.

  When the transverse plate 4 is moved in the longitudinal direction along the transverse plate lateral guide mechanisms 42 and 43 while being pivotally supported by the pile members 2 and 3 by the transverse plate support mechanism, the fixtures 7c and 7d which are transverse plate support mechanisms are used. Is in a loosely fixed state, there is a risk that the horizontal posture and the vertical position of the transverse plate 4 will shift. In preparation for such a case, the pile members 2 and 3 may be provided with a stopper member that prevents the transverse through plate 4 from sliding downward.

  FIG. 8 shows the stopper members 24 and 34. The stopper member is formed in a U-shaped cross section, and is fixed to the pile members 2 and 3 so as to sandwich the pile members 2 and 3 from both sides of the pile members 2 and 3, along the pile members 2 and 3. A moving mechanism that allows vertical movement is provided. A rib formed so as to extend in the vertical direction on the back surface of the pile members 2 and 3 as a moving mechanism, and a groove portion that is formed on a surface of the stopper member that faces the back surface of the pile members 2 and 3 and into which the rib is inserted. Can be configured.

  Each of the above-described embodiments is merely one aspect of the present invention, and the technical scope of the present invention is not limited by the description, and the specific structure and shape of each part are within the scope of the effects of the present invention. Needless to say, the size, material, and the like can be changed and designed as appropriate.
