Description

The present invention relates to a mounting height setting member for a slope reinforcing member mounting bolt for installing an anchor bolt for mounting a slope reinforcing member.

Various pressure receiving panels are attached to reinforce the slope. For example, Patent Document 1 and Patent Document 2 propose various pressure receiving panels. Any pressure receiving panel is attached to the tip of an anchor bolt installed on a slope in advance. An anchor bolt is passed through a hole in the center of the pressure receiving panel, and a nut is attached from above to install the pressure receiving panel.

For this purpose, the tip of the anchor bolt must protrude to the ground at an appropriate height that matches the pressure receiving panel. It can not be attached to lower if the nut than that, that excessively projecting nuts tip from slopes is higher. However, Patent Document 1 and Patent Document 2 do not particularly explain the installation method of the anchor bolt.

Until now, when installing anchor bolts, determine the protruding height using a ruler, etc., and fix the anchor bolts temporarily with a wooden stick etc. until the cement for fixing is hardened. The wooden stick was removed.

In the conventional installation of anchor bolts, temporary support of the anchor bolts is performed by combining wood or the like each time. However, mounting and removing of such support members is a complicated operation .

An object of the present invention is to provide a mounting height setting member for a slope reinforcing member mounting bolt that can be easily attached to and detached from the slope reinforcing member mounting bolt.

In order to solve the above problems, the mounting height setting member of the slope reinforcing member mounting bolt according to the present invention introduces the slope reinforcing member mounting bolt into the anchor mounting hole after digging the anchor mounting hole in the slope. This is a mounting height setting member for the slope reinforcing member mounting bolt, which is inserted into the cement for fixing the slope reinforcing member mounting bolt and installed at a desired height and then removed. A slope contact member that contacts the slope across the installation hole, and a slope reinforcement member attachment bolt connection member that is detachably connected to the slope reinforcement member attachment bolt. Further, the slope reinforcing member mounting bolt installation method of the present invention digs a hole for installing the slope reinforcing member mounting bolt on the slope, and attaches a mounting height setting member on the top of the slope reinforcing member mounting bolt, The slope reinforcement member mounting bolt is introduced into the hole, cement for fixing the slope reinforcement member mounting bolt is inserted, and the slope reinforcement member mounting bolt is projected to a predetermined length by the mounting height setting member until the cement is solidified. When the cement is solidified, the mounting height setting member is removed from the slope reinforcing member mounting bolt.

The mounting height setting member of the slope reinforcing member mounting bolt of this invention can be attached to the upper part of the slope reinforcing member mounting bolt by the slope reinforcing member mounting bolt connecting member, and the slope reinforcing member mounting bolt is used as the slope. Can be installed.

It is a front view which shows the attachment height setting member of a slope reinforcement member attachment bolt. It is the same side view. It is sectional drawing which shows the installation method of a slope reinforcement member attachment bolt. It is a front view which shows another example of the attachment height setting member of a slope reinforcement member attachment bolt.

EMBODIMENT OF THE INVENTION The form for implementing this invention is demonstrated in detail based on drawing. FIG. 1 is a front view showing a mounting height setting member of a slope reinforcing member mounting bolt, and FIG. 2 is a side view thereof.

The mounting height setting member 1 of the slope reinforcing member mounting bolt includes a slope contacting member 2 that contacts the slope GL and a slope reinforcing member mounting bolt connecting member that is detachably connected to the slope reinforcing member mounting bolt x. 3 and a slope reinforcing member mounting bolt upper end contact member 4 provided at a predetermined distance from the slope contact member 2.

The slope contact member 2 only needs to be wide enough to contact the slope GL across at least the anchor installation hole, and here, a metal rod is used .

The slope reinforcing member mounting bolt connecting member 3 is a member that can be detachably connected to an upper portion of the slope reinforcing member mounting bolt x serving as an anchor. Since the slope reinforcing member mounting bolt x is a metal rod that is usually called an anchor bolt and is provided with a male screw on the top, a member having a female screw that engages with the male screw is suitable. In this example, a nut is used and is fixed to the slope contact member 2 by welding. In addition to this, a clamp-like member that can be attached and detached by sandwiching may be applied.

An L-shaped metal rod 4 whose tip is bent at a substantially right angle is attached to the outer periphery of the nut which is the slope reinforcing member attachment bolt connecting member 3 by welding. The tip of the metal bar 4 is bent toward the inside of the nut. The distance L from the lower end of the bent portion 4a to the lower end (slope contact portion) of the slope contact member 2 defines the length that the slope reinforcing member mounting bolt protrudes from the slope, as will be described later. Yes, the distance L is set according to the desired protruding length.

Next, a method for installing a slope reinforcing member mounting bolt using a mounting height setting member and a method for installing a slope reinforcing member will be described. FIG. 3 is a cross-sectional view showing a method for installing a slope reinforcing member mounting bolt.

First, a hole y for installing the slope reinforcing member mounting bolt x is dug in a predetermined position on the slope. Usually, it is a position corresponding to the center of the slope reinforcing member, and in this example, a hole is formed in a direction perpendicular to the slope GL. However, other drilling angles may be selected depending on the construction method.

On the other hand, the attachment height setting member 1 is attached to the upper part of the slope reinforcing member attachment bolt x. The attachment height setting member 1 may be attached first or after the slope reinforcing member attachment bolt x is introduced into the hole y. In this example, the slope reinforcing member mounting bolt connecting member 3 is a nut having a female thread that engages with the upper end portion of the slope reinforcing member mounting bolt x, so that the nut 3 is connected to the upper end portion of the slope reinforcing member mounting bolt x. In accordance with the male screw, it is attached so that the upper end of the slope reinforcing member mounting bolt x hits the bent portion 4b of the slope reinforcing member mounting bolt upper end contact member 4.

The slope reinforcing member mounting bolt x is introduced into the hole y, and cement for fixing the slope reinforcing member mounting bolt x is added. While it takes some time for the cement to solidify, the slope reinforcing member mounting bolt x is supported by the mounting height setting member 1 of the present invention in a state in which the predetermined protruding length L is maintained. Until the cement is solidified, the installation work of the next slope reinforcing member mounting bolt may be started.

When the cement is solidified, the mounting height setting member 1 is removed from the slope reinforcing member mounting bolt x. In this example, the attachment height setting member 1 can be separated by rotating the attachment height setting member 1 in a direction away from the slope reinforcing member attachment bolt x. The collected mounting height setting member 1 can be reused. In this way, the slope reinforcing member mounting bolt x is installed on the slope GL in a state where an appropriate protruding length is realized.

Then, there is no particular limitation on the subsequent work of attaching the slope reinforcing member, and a conventional method can be applied as it is. For example, a hole at the center of a slope reinforcing member z composed of a concrete plate, a metal plate, or a lattice-like member is applied to the slope reinforcing member mounting bolt x, and the slope reinforcing member z is attached with a mounting member such as a nut. Fix it. Since the slope reinforcing member mounting bolt x is installed with an appropriate protruding length, these operations can be performed reliably and accurately. Even after the construction, the slope reinforcing member mounting bolt x protruding excessively is not present, and the tip portion thereof is aligned at a uniform height.

Furthermore, another example of the mounting height setting member of the slope reinforcing member mounting bolt will be described. FIG. 4 is a front view showing another example of the mounting height setting member of the slope reinforcing member mounting bolt.

In this example, a nut is welded to the central portion of one metal bar. Here, the metal rod is connected so as to straddle the upper surface of the nut, and this portion becomes a slope reinforcing member mounting bolt upper end contact member. On the other hand, the portion of the metal rod extending on both sides of the nut functions as a slope contact member.

The method of installing the slope reinforcing member mounting bolt and the method of installing the slope reinforcing member using the mounting height setting member of this example are the same as the example shown in FIG. When the mounting height setting member of this example is used, the height of the upper end of the slope reinforcing member mounting bolt x is the same as the height of the slope GL. Some slope reinforcing members have a depressed central portion, and can be used when installing such a slope reinforcing member. Therefore, in the present invention, the predetermined distance from the slope contact member includes a case where the distance is 0 or a negative value.
