DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support plate device for anchor anchoring having a function of correcting axis deviation of an anchor.

[0002]

2. Description of the Related Art An anchor construction method has been known as a method for preventing a slope from collapsing, in which an anchor having a length reaching a deep part of the ground is formed, and the anchor is tensioned and fixed from the slope side to restrain the collapsed soil. I have. In this anchor method, as shown in FIG. 6, a pressure receiving plate c made of a concrete block or the like is inserted into an anchor b protruding from a slope a, and further, a supporting plate d and a pedestal e are inserted into the anchor b to be tensioned and fixed by a fixing device f. are doing. At this time, the pedestal e is formed by providing an angle in advance on its front surface and back surface so that the axis of the anchor b in the fixing device f and the axis of the anchor b located in the ground are on the same straight line. I have.

[0003]

However, the above-mentioned conventional anchor head fixing technique has the following problems.

<A> Due to the unevenness of the slope a and the inclination due to the molding error of the pressure receiving plate c on which the pedestal e is mounted, the axis of the anchor b exposed from the pressure receiving plate c and the axis of the anchor located in the ground are determined. It is technically difficult to position the two on the same straight line. Therefore, when fixing is performed in such a state, the anchor b is easily bent and broken at the fixing device f.

<B> As a method for solving the above-mentioned problems, there are a method of accurately shaping the installation surface of the pressure receiving plate c and a method and a shape (inclination angle) of manufacturing the pedestal e according to the condition of the site. A method of manufacturing a plurality of types of pedestals e and cambers (not shown) different from each other and selectively using the pedestals e and the cambers according to the state of the site can be considered. All of these methods are burdensome in terms of construction cost and construction period, and the management becomes complicated, which makes them less feasible, and the basic problems cannot be completely solved.

May be omitted.

<B> Installation of Substrate / Laying Board Before the hardening material is hardened, the substrate 30 is put on the mouth of the anchor 50 and seated on the ground 60. When the substrate 30 is mounted, the guide tube 40 functions as a guide member. Next, the floor plate 21 is installed on the substrate 30. Before the installation of the base plate 21, the convex body 22 is fixed to the upper surface of the base plate 21 in advance by welding or the like. Then, as shown in FIG. 3, the guide tube 40 extending from below is inserted into the center hole 211, the bolt 31 protruding from the substrate 30 is inserted into the elongated hole 212, and the floor board 21 is disposed on the substrate 30. Furthermore, convex body 2

A nut is attached to each of the bolts 31 extending from the base 12, and the floor plate 21 is fixed to the substrate 30.

<C> Installation of Transmission Tube As shown in FIG. 4, the concave surface 121 of the curved plate 12 is
The transmission tube 10 is arranged on the pedestal 20 so as to match the second convex surface 222. At this time, the direction of the transmission cylinder 10 is determined by lowering the transmission cylinder 10 so as to match the direction of the transmission cylinder 10 with the direction of the anchor 50 extending from the guide tube 40. Then, the fixing device 5 is placed on the fixing plate 13 of the transmission cylinder 10 via the support plate 52.
1 is set, and the anchor 50 is primarily tensioned.

<D> Construction of pressure receiving plate After temporarily anchoring the anchor 50, a pressure receiving plate 53 made of reinforced concrete is constructed around the substrate 30. The pressure receiving plate 53 is constructed such that the fixing plate 13 is exposed on the upper surface thereof. When the pressure receiving plate 53 is completely cured, the anchor 5
0 is re-tensioned with a predetermined strength, and the anchoring work is completed.

Embodiment 2 A curved plate 12 is provided at the lower end of the transmission tube 10 of Embodiment 1.
A convex surface is provided in place of, and a concave surface is formed on the upper surface of the pedestal 20,
The transmission cylinder 10 may be configured to be able to adjust the inclination angle with respect to the pedestal.

[0020]

Third Embodiment As shown in FIG. 5, a spherical body may be attached to the lower end of the transmission cylinder 10 instead of the curved plate 12, and a concave surface may be provided on the upper surface of the pedestal 20 without attaching the convex body 22. That is, the support plate device of the present embodiment includes the transmission cylinder 10a having the sphere 14 attached to the lower end, the pedestal 20b having the concave surface 23 on the upper surface, and the substrate 30. The concave surface 23 is a spherical concave surface, and a center hole 211b is formed at the center of the concave surface 23 so as to penetrate the pedestal 20b. The center hole 211b is preferably formed in a tapered shape whose diameter increases downward so that the inserted anchor 50 does not contact the peripheral surface. Further, the concave surface 23 is formed to have a size that fits the spherical body 14. For this reason, the spherical body 14 freely rotates within the concave surface 23, and the transmission cylinder 10a can be directed in any direction about the spherical body 14. Therefore, the transmission tube 10a can be easily set according to the angle of the anchor 50 derived from below, and the anchor 50 does not bend. In the case of the present embodiment, the pedestal 20b and the substrate 30 may be provided integrally.

As described above, the present invention has the following effects.

<A> The pedestal was attached to the substrate so as to be freely rotatable, and the transmission cylinder was attached to the pedestal so as to be adjustable in inclination. For this reason, the transmission cylinder can be set in any direction with respect to the substrate. Therefore, the axis of the anchor exposed from the pressure receiving plate and the axis of the anchor located in the ground can be completely located on the same straight line. No risk of breakage.

<B> Since the transmission cylinder and the pedestal have a simple structure, they can be manufactured at low cost.

<C> The transmission tube can be easily set in any direction, despite its simple structure. Therefore, the anchoring operation of the anchor head can be performed quickly.
