Description

[Detailed description of the invention] (Field of industrial application) This invention is applicable to anchor bolts buried in the railings, for example, in order to install soundproof walls on top of concrete railings on the side of roads in the future. The present invention relates to a decorative plate for an anchor bolt for covering the upper end of the anchor bolt, that is, when the anchor bolt is not in use.

(Prior Art) Conventionally, anchor bolts buried in concrete railings to install soundproof walls, etc., are
The upper ends of the bolts may be left protruding from the top of the railing until a soundproof wall is installed, or a concrete or wooden block is placed on the top of the railing and is removably attached to the top of the anchor bolt. was covered.

(Problem that the invention aims to solve) However, if the upper ends of the bolts are left protruding from the top of the railing, the beauty of the surrounding area will be significantly impaired, and the protruding upper ends of the bolts may cause injuries or accidents. There was a risk that this would occur. In addition, when concrete or wooden blocks are used, although the above problems have been solved to a certain extent, it is still not sufficient; the blocks are heavy, making construction time-consuming, and heavy blocks of various sizes are required. There were problems in that it was troublesome to transport and store the blocks, and the cost was relatively high. Furthermore, wooden blocks had the problem of poor durability.

The object of the present invention is to provide a decorative plate for anchor bolts that solves these conventional problems.

(Means for solving the problem) In order to solve the above problem, the decorative plate for anchor bolts of the present invention is made into a lightweight box shape with a fresh concrete input opening at the top, and is buried in the concrete base. It has a bolt insertion hole that penetrates vertically to correspond to the anchor bolt.

(Example) The present invention will be described below with reference to the drawings.

In the drawings, A is the decorative plate of the present invention, which is made of synthetic resin, metal, or the like. The decorative plate A has a suitably shaped lightweight box shape, generally a substantially rectangular lightweight box shape, with a fresh concrete inlet 1 opened at the top. The fresh concrete inlet 1 may be provided so that a part of the top surface of the decorative plate A is opened as shown in FIG. 1, or may be provided so that the entire top surface is opened as shown in FIG. Further, the decorative plate A is provided with bolt insertion holes 2 that pass through it vertically. Bolt insertion holes 2 are provided corresponding to anchor bolts 7 to be buried in a concrete base 6, which will be described later. Further, in the case of FIG. 3, the bolt insertion holes 2 are formed in the upper and lower surfaces of the decorative plate A, and a cylindrical body 3 is provided between the holes. The cylindrical body 3 is shaped such that its upper part is widened so that a countersunk bolt 4 can be inserted therethrough, and is installed so that the countersunk bolt 4 inserted therein does not come into direct contact with the concrete 5 filled inside the decorative plate A. . In the case of FIG. 6, the bolt insertion hole 2 is bored in the lower surface of the decorative plate A, and the cylindrical body 3 is provided in alignment with the hole in the lower surface during use.

The decorative plate A of the present invention is applied to a concrete base 6 such as a concrete railing generally installed on the side of a road.
It is removably attached to the upper end of the anchor bolt 7 buried in the concrete base 6 at the same time as construction.
This will be explained with reference to FIGS. 3, 3, and 4.

First, before constructing the concrete base 6, an anchor bolt 7 is installed at a predetermined location, and a joint nut 8 is screwed onto the upper end of the anchor bolt 7. Next, the bolt insertion hole 2 of the decorative plate A is made to correspond to the joint nut 8 of the anchor bolt 7, and the countersunk bolt 4 is
is screwed into the joint nut 8 through the bolt insertion hole 2 to fix the decorative plate A. Next, concrete is poured to form the concrete base 6, and the fresh concrete inlet 1 of the decorative plate A is poured.
Fill the inside of the decorative plate A with concrete 5. At this time, it is preferable to insert a reinforcing material such as a reinforcing bar or a wire mesh inside the decorative plate A to improve the strength. Note that the decorative plate A may be attached after the concrete base 6 is constructed, instead of being attached at the same time as the coiclete base 6 is constructed.

The above state is maintained until a structure 9 such as a soundproof wall is installed on the concrete base 6, that is, when the anchor bolt 7 for fixing the structure 9 is not used. When installing the structure 9, loosen the countersunk bolts 4, remove the decorative plate A, and fix the structure 9 with the mounting bolts 10 and nuts 11 screwed into the joint nuts 8 as shown in FIG. In addition, in FIG. 5, 12 is a non-shrinking mortar.

(Effects of the invention) As detailed above, the decorative plate of the present invention has a box shape with a fresh concrete input opening at the top, so it is lighter in weight than conventional concrete or wooden blocks, and is easier to construct. In addition to being convenient for transportation and storage, the cost can also be reduced. In addition, plates of various sizes can be easily constructed, and are durable and aesthetically pleasing.

In addition, it has a box shape with a fresh concrete input opening at the top, and bolt insertion holes are penetrated at the top and bottom to accommodate anchor bolts, so when installing structures such as soundproof walls on the concrete base, Can be easily removed from the anchor bolt. or,
At the same time as concrete base construction, it is attached to an anchor bolt and concrete can be poured into the plate from the fresh concrete inlet, making construction easier.
