Description

  The present invention relates to a survey point display plate that is installed at a survey point, a boundary, or the like and displays a point.

  A large number of surveying point display plates are usually installed at predetermined intervals or at predetermined locations over a wide area such as a city unit or an address block unit. Each sheet has a slightly different display content, and many are installed in a limited space such as on an outdoor road.

  Conventionally, as this survey point display plate, there is a combination plate formed by combining an internal plate on a fixed plate fixed to the ground (see, for example, Patent Document 1).

  The conventional combinable plate has the following advantages. In other words, by installing a combination of different shapes of internal plates on the surface of a washer-like combinable plate, the display content can be easily given a width, or even if the shape of the internal plates is different, The appearance can be arranged by unifying them.

  Specifically, the above-described conventional combinable plate configuration is such that a recessed portion in which the inner plate is accommodated is provided on the upper surface of a substantially rectangular plate, and a columnar central protrusion is provided at the center thereof. This is because the tip of the central protrusion is projected through the center hole of the inner plate by fitting the inner plate in which the central hole is formed, through the central hole of the inner plate, and the tip of the protrusion is It is crushed and spread, and is fixed integrally with the inner plate combined with the washer plate. Then, it is fixed with a nail or the like together with the internal plate in the combined state, and is installed on the ground or the like.

  Here, since a large number of surveying point display plates are installed over a wide area such as a municipality or a division unit, it is necessary to perform easy and reliable fixing to a grounding point. Moreover, since it is always installed outdoors and exposed to severe external environments such as wind and rain, it must be securely fixed to a grounded location such as the ground. In particular, the combinable plate as described above needs to be fixed more securely so that the combination is not released.

  However, in the conventional plate, it is relatively difficult to uniformly crush the protrusion around the periphery, and if it fails to be crushed, fixing is not sufficient, such as insufficient fixation. It was.

Moreover, since it fixes only by the center protrusion, an internal plate may rotate, and it will become a bad appearance by rotating the display of an internal plate.

  It is an object of the present invention to provide a survey point display plate that securely fixes the internal plate P and is excellent in appearance by unifying the display direction.

  In order to solve the above problems, the following means (1) to (4) are adopted.

(1) The survey point display plate of the present invention includes a flat plate 1 on which an internal plate P can be disposed at an internal plate disposition position on the upper surface, and a crush margin provided at a plurality of locations around the internal plate disposition position. And a presser claw 2 that holds the inner plate P. The crushing margin 21 of the holding claw 2 has a top portion 2t in the vicinity of the outer periphery in plan view of the disposed inner plate P, and has an outer surface 2o inclined so as to spread outward from the top portion 2t in plan view. And
By applying an impact force from above the plate to the outer side surface 2o by the striking means, the top portion 2t of the crushing margin 21 is brought down to the arranged inner plate P side, and the crushing margin 21 is arranged on the arranged inner plate. It is crushed so as to cover P, and is in a fixed state in which the internal plate P is fixed to the flat plate 1.

  By crushing the crushing margin 21 of each presser claw 2, it can be fixed to the upper surface of the flat plate 1 (the survey point display plate of the present invention) so as to press a plurality of positions around the disposed internal plate P.

(2) the flat plate 1 has on its upper surface, Ri Na provided substantially regular hexagonal fitting recesses 11 of the internal plate P can fitted, when the internal plate P is fitted, the fitting recess 11 is At least a part of the outer periphery of the inner plate P is brought into contact with the inner plate P so that positional displacement of the inner plate P after the placement is suppressed. It is preferable. By fitting the inner plate P in the fitting recess 11, the inner plate P can be more securely fixed by the presser claw 2.

  (3) The crush margin 21 of the presser claw 2 has at least the outer side surface 2o as a top portion 2t in the vicinity of the outer periphery in plan view of the disposed internal plate P, and spreads outward from the top plate 2t to the outer side in plan view. Thus, it is preferable to have an inclined outer surface.

  By applying force (striking or crushing) to the outer surface 2o from above the plate, the crushing allowance 21 is crushed, so that the crushing allowance 21 is crushed so as to cover the disposed internal plate P.

  (4) In the presser claw 2, the inner plate facing surface 2 i facing the disposed inner plate P is inclined from the disposed position of the inner plate P toward the outer top portion 2 t (an installation surface). Or a plane perpendicular to the surface).

  That is, the presser claw 2 is composed only of a vertical surface or an outer inclined surface, and does not have an inner inclined surface that is inclined inward to the inner side. If it is such, a stamping (pressing) process becomes possible and it can shape | mold easily. The inner plate facing surface 2i is along the outer periphery of the disposed inner plate P in plan view. The internal plate facing surface 2i of the embodiment is a flat surface slightly inclined from the top 2t toward the internal plate P.

The back surface of the flat plate 1 is provided with a plurality of continuous minute concave and convex shapes (specifically, for example, knurling) as anti-slip means 12 that is anti-slip with respect to the installation surface (FIG. 4 and the like). Further, as a display direction indicating means for indicating the display direction of the front surface, a manufacturer display pattern is attached to one of the four corners on the back surface (not shown).

(Fixing hole 13)
In the flat plate 1, fixing holes 13 for fixing to the installation surface are provided at the center of the inner plate disposition position and symmetrical positions near the left and right ends of the flat plate 1. The right and left fixing holes 13 a provided at symmetrical positions near the left and right ends are inner cones whose diameter decreases from the upper surface to the lower surface of the flat plate 1, and the heads of the countersunk screws reach the same height as the upper surface of the flat plate 1. It is supposed to fit. The center fixing hole 13b provided at the center of the inner plate disposition position is provided with the inner plate P and the flat plate plate 1 as required when the fixing hole 13 is provided at the center of the inner plate disposition position. Both are pierced with screws (nails, anchor bolts, etc.) and struck against the installation surface. Thereby, the inner plate P and the central flat plate 1 can be further firmly fixed, and at the same time, the flat plate 1 can be firmly fixed to the installation surface.

  However, these fixing holes 13 are not necessarily required. The flat plate 1 is fixed by an arbitrary fixing means such as application of an adhesive to the back surface of the flat plate 1 or embedding and fixing in a structure such as mortar.

(Presser claw 2)
Accordingly, the plurality of pressing claws 2 are provided on the outer side in plan view from the periphery of the inner plate placement position so as not to overlap with the inner plate placement position in plan view. The presser claws 2 of the first embodiment project two presser claws 2 at a pair of opposing corners of the fitting recess 11 in a substantially regular hexagonal shape in plan view so as to protrude toward the center in plan view and upward in front view. Provided. Of the pair of opposing corners of the substantially regular hexagon in plan view, a pair on the diagonal diagonal line in plan view is selected as being away from the left and right fixing holes 13b, and the holding claws 2 are provided here (FIGS. 2 and 2). 3).

  Specifically, each presser claw 2 includes an inner plate facing surface 2i facing the outer periphery of the disposed inner plate P, and an outer surface 2o in the outer side direction in plan view excluding the inner plate facing surface 2i. In addition, the inner plate P is formed in a substantially partial mountain shape having a top portion 2t in the vicinity of the outer periphery in plan view. The top 2t is located in the vicinity of the center in the width direction of the pressing claw 2 in the plane between the inner plate facing surface 2i and the outer surface 2o (FIGS. 2 and 6).

(Crushing cost 21)
The crushing allowance 21 has a function of plastic deformation that crushes in a direction covering a plurality of locations around the disposed internal plate P from above. The shape is a mountain shape or a partial mountain shape depending on the inclination direction of the outer surface 2o. In the embodiment, the partial mountain shape is a half mountain shape that is cut in half by a vertical surface perpendicular to the installation surface. The cut surface is the inner plate facing surface 2i, and the inner plate facing surface 2i has a bilateral mountain shape that is symmetrical.

  When the crushing margin 21 of the presser claw 2 is cut along the radial vertical surface (cross section AA) of the disk-shaped inner plate P, a substantially right triangle is formed as shown in FIG. In FIG. 4, the elevation angle of the outer surface 2 o, that is, the base angle θ of a substantially right triangle in front view or vertical section view, is greater than about 45 °. Thereby, the big crushing allowance 21 can be ensured. Moreover, when it cut | disconnects by the vertical surface (BB cross section) orthogonal to the radial direction of the disk-shaped internal plate P, the vertical substantially parabolic mountain shape which spreads in the downward direction like FIG. 6 is comprised. Then, in a plan view, when cut along an arbitrary horizontal plane, as shown in FIG. 2, a substantially partial arc having a curved outer side and a straight inner side (more specifically, a circumscribed line of the inner plate P) is formed. Out of this substantially partial arc, the outer curve is the outer surface 2o, and the inner straight line is the inner plate facing surface 2i.

(Outer surface 2o)
The outer side surface 2o of the first embodiment constitutes an outer side surface of the crushing margin 21 that faces away from the arrangement direction of the inner plate P. At least the outer surface 2o has an outer inclined surface that is inclined so as to extend from the top 2t to the outer side in plan view from the inner plate P. The outer side surface 2o is an outer inclined surface that is inclined so that the vicinity of the outer periphery of the inner plate P in plan view is a top portion 2t and further spreads outward from the vicinity of the outer periphery of the inner plate P in plan view. The inclined surface of the outer surface 2o may be a flat surface or a curved surface.

(Internal plate facing surface 2i)
The inner plate facing surface 2i is a surface facing the disposed inner plate P, and is a surface shown on a substantially parabola in FIG. It may be constituted by an inclined surface inclined from the inner plate P (positioning position) toward the outer top 2t or a vertical surface perpendicular to the installation surface. The inner plate facing surface 2i is along the outer periphery of the inner plate P arranged in a plan view (FIG. 2). The inner plate facing surface 2i of the present embodiment is a flat surface slightly inclined from the top 2t toward the inner plate P.

  That is, the presser claw 2 of the present embodiment is composed of only a vertical surface or an outer inclined surface as a whole, and does not have an inner inclined surface that is inclined inward toward the inside. If it is such, a stamping (pressing) process becomes possible and it can shape | mold easily.

(Raised stand 22)
Each presser claw 2 is provided with a raised base 22 raised above the flat plate 1 at the base end (base) of the crushing allowance 21 (FIGS. 4 and 6). That is, each presser claw 2 is formed of a stepped mountain shape with two or more steps, at least the lowest step being the raised base 22 and at least the uppermost step being the crushing margin 21 (FIG. 6). The ridge stand 22 of the embodiment is composed of a trapezoidal flat plate base having the same ridge height, and constitutes a two-tiered lower stage. The upper stage of the two-tier mountain type is the crushing allowance 21.

  The raised table 22 can be a strong presser claw 2 that is not easily separated from the flat plate 1 even when force is applied by an impact or the like. Alternatively, it is possible to suppress the surface of the flat plate 1 from being dented or severely damaged due to impact caused by striking.

(Fixing method)
The survey point display plate of the present invention is fixed by, for example, the following fixing method. First, the flat plate 1 is installed at the installation location without the internal plate P being combined, and the anchor pins Nb and the like are inserted through the left and right fixing holes 13b and fixed to the installation location. At this time, an adhesive may be applied to the back surface of the internal plate P.

  Next, the internal plate P is disposed at the position of the internal plate on the surface of the flat plate 1 and fixed to the upper surface of the flat plate 1. Basically, the flat plate 1 is fixed on the flat plate 1 by pressing the crush allowances 21 of the press claws 2 so that a plurality of positions around the disposed internal plate P are pressed.

  Specifically, an impact force or a pinching pressure is applied from above the plate by hitting the outer surface 2o with a striking means such as a hammer or crushing with a pinching means such as a pliers. Thereby, the top part 2t of the crushing allowance 21 is brought down to the disposed internal plate P side (FIGS. 3, 5, and 7). The crushing allowance 21 is crushed so as to cover the disposed internal plate P, and is in a fixed state in which the internal plate P is fixed to the flat plate 1.

  Thereafter, if necessary, the center fixing pin Nb (nail, anchor pin, etc.) can be inserted into the center fixing hole 13b together with the center hole of the inner plate P, and this can be driven into the grounding location (FIG. 3). As a result, the fixed state can be held more firmly.

  In Example 2 (FIG. 8), a substantially circular fitting recess 11 having substantially the same inner diameter as or slightly larger than the inner plate P, and three locations obtained by dividing the substantially circular shape of the fitting recess 11 into three equal parts at substantially equal intervals. The three holding claws 2 having a substantially rectangular shape in plan view projecting in the center direction (inner side) in plan view. The presser claw 2 of the second embodiment does not have the raised base 22.

  Example 3 (FIG. 9) is a substantially regular hexagonal fitting recess 11 that is substantially the same inner diameter as or slightly larger than the inner plate P, and four planes that are planar and out of the substantially regular hexagonal shape of the fitting recess 11. And four holding claws 2 having a substantially rectangular shape in a plan view projecting in the center direction (inner side) in the plan view. The presser claw 2 of the second embodiment does not have the raised base 22.

  Example 4 (FIG. 10) is a plan view center direction (at least two points facing each other among the fitting dent 11 substantially the same inner diameter as or slightly larger than the inner plate P and the substantially regular hexagon of the fitting dent 11). And at least two presser claws 2 that are substantially rectangular in plan view and projecting inwardly). The crush margin 21 of the presser claw 2 of the fourth embodiment is formed in a horizontally long rectangular shape in cross section so as to cover the upper surface of the disposed internal plate P before being crushed. When the crushing margin 21 having a horizontally long rectangular shape in cross section is applied with a force from above, the tip on the center side is curved downward to hold the inner plate P (not shown).

  In the second, third, and fourth embodiments, other main configurations that are not specified are the same as those in the first embodiment. In addition, this invention is not limited to each Example, A various deformation | transformation is possible in the range which does not deviate from the meaning of this invention.

  The survey point display plate of the present invention can be used as various display plates such as a signboard display and a nameplate display in addition to the display of survey points.
