BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a benchmark display tool for displaying the height of a building as a standard.

[0002]

2. Description of the Related Art In constructing a building, it is necessary to set an origin, which serves as a height reference, at a predetermined position on or near the site and to indicate that the position is the origin. This origin is called a benchmark, and the period during which construction is performed, especially the period until the foundation is completed, is an important criterion for determining the height of a building.

[0003]

Here, the benchmark is generally displayed by drawing a horizontal line on a fixed object such as a utility pole, a retaining wall, a block wall, or a standing tree inside or outside the site by using a felt-tip pen, for example. However, in such a display method, there are problems that the display becomes difficult to see due to dirt adhered or washed away due to rain, and that it is troublesome to turn off the display after the construction is completed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a benchmark display device which is easy to install and remove and has high visibility.

[0005]

In order to achieve the above object, the benchmark display device of the present invention has a predetermined structure of a main body fixed to a fixed object such as a utility pole or a retaining wall as described in claim 1. In addition to providing a sign indicating that the site is the reference height, an information sheet describing information about the sign is detachably attached to the main body.

Further, the benchmark display device according to the present invention is such that a display holder made of a transparent material is attached to the main body, and the information sheet is stored in the display holder.

Further, the benchmark display tool according to the present invention is configured such that the mark is formed by a linear pattern by coloring, embossing, slits or the like.

Further, the benchmark display tool according to the present invention is such that the linear patterns are arranged orthogonally.

Further, in the benchmark display tool according to the present invention, the predetermined portion is a peripheral edge of the main body.

In the benchmark display device of the present invention,
The main body provided with the sign is fixed to a fixed object such as a telephone pole, and information indicating what the height of the sign means in terms of design is displayed on an information sheet and attached to the main body. On the information sheet, for example, it is displayed that the position 400 mm lower than the sign is the average GL. Then, the height direction is measured by using these signs as a reference, and the site is excavated and the foundation is constructed in sequence. After the construction is completed, the main body is removed from the fixed object, and the information sheet is also removed from the main body and replaced with a new one, to prepare for the next diversion.

Here, when the marker is constituted by a linear pattern formed by coloring, embossing, slits, etc., if the benchmark display is attached so that the linear pattern is horizontal, the linear pattern will be at the origin of height. You can see at a glance what is there, and it will be easier for the workers on the site to check. Further, by arranging the straight line patterns at a right angle, the benchmark display tool can be mounted vertically or horizontally depending on the fixed object.

Further, when a display holder made of a transparent material is attached to the main body and the information sheet is stored in the display holder, characters or numbers on the information sheet may be smeared or soiled by rain. There is no danger of becoming unreadable.

Further, when the predetermined portion is the peripheral edge of the main body, a triangle-shaped arrow, for example, is attached in the vicinity of the peripheral edge to form a marker, which indicates that the height is a reference.

The markers 4 and 5 are formed in a linear pattern so that the height reference can be seen at a glance from a distance. For example, colors such as red and green are applied or embossing or It can be configured by slit processing. Further, fluorescent paint can be used in consideration of night work.

The markers 4 and 5 are arranged at positions orthogonal to each other, so that the benchmark display tool 1 can be mounted vertically or horizontally depending on the fixed object. ing. In the present embodiment, for convenience, the markers 4 and 5 will be described as being embossed and colored red and green, respectively.

A predetermined hole 6 is formed in the plate 2, and by inserting a nail, a screw or the like into the hole 6, the plate 2 can be easily fixed to a stand or the like. A double-sided adhesive tape 7 is attached to the back surface of the plate 2 so that it can be easily fixed to the side surface of a concrete retaining wall, its top end, manhole top end, and the like. The plate 2 is made of a weather resistant and light material, such as stainless steel or plastic,
It is preferable that the width is, for example, 30 mm, and the lengths of the triangular portion and the rectangular portion are about 20 mm and 70 mm, respectively.

On the other hand, a slit 8 is formed at the other end of the plate 2 which is the main body, and the end of the display holder 3 is wound around and fixed to the slit 8. The display holder 3 is
It has a bag-like shape, at least the front side of which is made of a transparent material such as vinyl, and the other end thereof is provided with an airtight fastener 9 as used in a food storage bag. Then, the fastener 9 is opened to insert an information sheet in which information regarding the marker 4 or the marker 5 is inserted, and this can be stored in the display holder 3.

Next, a method of using the benchmark display tool 1 will be described.

First, the situation of the site and its surroundings is grasped to select a place suitable for installing the benchmark display tool 1, and the level in the site is measured by a commonly known method to set the average GL. . Next, the benchmark display tool 1 is attached to a predetermined place.

FIG. 2A shows a state in which the benchmark table jig 1 is attached to the side surface of the retaining wall 11. Here, the benchmark display tool 1 is laterally fixed with an adhesive tape 7 so that the marker 4 is located at a predetermined height position. The benchmark display tool 1 can be installed at an arbitrary height position, but if it is installed near the ground, it may be damaged. Therefore, as shown in FIG. It is preferable to position and install the marker 4 at a height 400 mm higher than the average GL 13.

On the other hand, as shown in FIG. 2B, two strip-shaped information sheets 21 made of, for example, paper are prepared, and information about the marker 4, that is, "height of red line- Write 400 characters = average GL "with a felt-tip pen and insert them into the display holder 3.
Close the zipper 9 tightly to prevent rain.
If the information sheet 21 is made of, for example, a yellow background and a black character sticker is attached to the sheet, a noticeable color scheme that can alert the operator, as well as readability and appearance will be improved.

When the benchmark display tool 1 is attached in this manner, the height direction is measured by using the marker 4 as a reference, and site excavation and foundation construction are sequentially performed. Then, when the construction is completed, the benchmark display tool 1 is removed from the retaining wall 11, the information sheet 21 is removed from the display holder 3 and replaced with a new one, in preparation for the next diversion.

FIG. 3 shows the benchmark display 1 with the utility pole 31.
It shows how it is attached to. Even in such a case, the average GL 13 to 4 is adjusted according to the top of the foundation 12.
Although the benchmark display tool 1 is attached so that the height is increased by 00 mm, unlike the case of FIG. 2, the benchmark display tool 1 is arranged in the vertical direction so that the marker 5 is horizontal, and the marker 5 is installed as described above. And the information sheet 21 correspondingly displays the characters "height of green line-400 fall = average GL". When fixing the plate 2 to the electric pole 31, the adhesive tape 7 may be used, or nails or screws for wood or concrete may be passed through the hole 6 and fixed to the electric pole 31. In addition, it is possible to install it on a standing tree or the like by the same method.

FIG. 4 shows how the benchmark display tool 1 is mounted on the manhole 41. In such a case, the tip of the mark 4, that is, the plate 2
If the top of the manhole 41 is lower than the average GL by 100 mm, for example, if the tip of the triangular portion of the manhole 41 is located at the center of the manhole 41 and the top of the manhole is 100 mm lower than the average GL, the information sheet 21 reads "manhole top +100". Rise = average GL ". In addition, it is possible to install it on the roof top of the trout, the top of the retaining wall, the top of the gutter, etc. in the same manner.

As described above, according to the benchmark display tool of the present embodiment, the plate serving as the main body is provided with a mark serving as a height reference, and the plate is attached to a fixed object such as a retaining wall and the benchmark is displayed. Since the information about the benchmark is written on the information sheet and attached to the main body, the visibility of the benchmark is improved compared to the conventional method where the benchmark was displayed directly on the retaining wall etc., and the worker should be a benchmark at first glance. You can check and understand the contents immediately.

Further, according to the benchmark display tool of the present embodiment, since the adhesive tape is attached to the back surface of the plate and the holes of the nails and the screws are punched in the plate, these can be used properly according to the material of the fixed object. Alternatively, by using together, it is possible to easily install and remove.

Further, since the information regarding the height of the sign is displayed on the information sheet and is stored in the display holder, by removing the information sheet and replacing it with a new one, the information sheet can be repeatedly used at different sites. Can be used repeatedly.

Further, since the information sheet is housed in the transparent display holder, there is no risk that the information sheet gets wet or soiled by rain and the characters and numbers on the sheet become unreadable.

Further, since the sign is composed of a linear pattern by coloring, embossing, slits, etc., if the benchmark display is attached so that the linear pattern is horizontal, the linear pattern is the origin of height. This makes it easier for workers in the field to check things at a glance. Further, since the straight line patterns are further arranged at right angles, the benchmark display tool can be mounted vertically or horizontally depending on the fixed object.

In the present embodiment, the markers having a linear pattern are arranged orthogonally, but one marker may be omitted if the benchmark display tool is always used in a fixed direction.

Further, in the present embodiment, the height reference mark is formed by a linear pattern, but it is not necessarily a linear pattern and may be, for example, a triangular arrow pattern. Further, in the present embodiment, the predetermined portion having the reference height is, for example, the center of the plate surface, and the marker 4 having a linear pattern is provided at the portion, but the predetermined portion having the reference height may be, for example, the peripheral edge of the plate.

FIG. 5 shows a benchmark display tool 51 according to this modification. As you can see in the figure,
Similar to the benchmark display tool 1, the benchmark display tool 51 is also configured by attaching the display holder 3 to a substantially rectangular plate 52 which is a main body, but instead of the linear pattern markers 4 and 5, a triangular pattern marker 53. Through sign 55
Is attached to the plate 52, and the upper edge, the left edge, and the upper left corner of the plate 52 are respectively indicated as the reference height, which is different from the above-described embodiment.

Further, although the present embodiment has been described on the assumption that the information sheet is exchanged at each site, for example,
If the information sheet is composed of a plastic plate, information is written on it with a felt-tip pen, etc., and after the construction is completed, the plastic plate can be taken out from the display holder to erase characters etc. can do.

Further, in this embodiment, the information sheet is stored in the display holder, but if stains or bleeding do not pose a problem, the information sheet can be attached to the plate which is the main body by other means without using the display holder. It only needs to be detachably attached. When the information sheet is detachably attached to the plate, various design changes can be made by using known means.

FIG. 6 shows such a modification. As shown in the figure, in the benchmark display tool 61 according to the modified example, a pair of claws 63 are arranged facing each other on the surface of a substantially rectangular plate 62 which is a main body, and an information sheet 64 shown in FIG. As shown in FIG. 3D, the claw 63 and the plate 6
It can be sandwiched between two. In addition, the plate 62 has a marker 53 similar to that of the modified example described above.
A label 55 is attached.

FIG. 7 shows the benchmark display tool 61 as the retaining wall 1.
1, the state of being attached to the telephone pole 31 and the manhole 41 is shown. As can be seen from the figure, the method of using the benchmark display tool 61 is basically the same as that of the benchmark display tool 1, but the portion indicating the reference height is set on the plate 62.
Due to the peripheral edge, the attachment position to the fixed object is slightly different from that of the benchmark display tool 1.
