Description

  The present invention, for example, when various structures such as steel or resin (curing) floor plates and mats are placed (placed) on various base surfaces such as road surfaces, ground surfaces or floor surfaces. The present invention relates to a step eliminating block (also referred to as a step eliminating slope) for eliminating a step formed by a base surface and an end surface of the structure (a side surface of the structure positioned in a state of being raised from the base surface).

  Conventionally, as this kind of step elimination block (slope), in the state where the step is constituted by the base surface and the end surface of the structure, the step is eliminated between the end surface of the structure and the base surface. Known is one having an inclined portion capable of forming a slope (for example, Patent Document 1: “Title Slope” of the invention), and one end side of the inclined portion with respect to the end surface of the structure is known. It is fixed so that it can rotate freely.

  According to such a configuration, by fixing one end side of the inclined portion to the end surface of the structure, the inclined portion can be installed with a downward gradient from the upper end surface of the structure toward the upper base surface. Therefore, the step between the end surface of the structure and the base surface can be eliminated. As a result, there is no obstacle to the traffic of people and vehicles, and an external load acts directly on the end surface by interposing an inclined portion between the end surface of the structure and the base surface. Since this can be eliminated, early deterioration of the end face (and consequently the structure) can be prevented in advance.

  By the way, in the conventional level difference cancellation block (slope) as shown in Patent Document 1, when installing the inclined portion between the end surface of the structure and the base surface, by a fastener such as a predetermined screw or bolt, A method is adopted in which one end side of the inclined portion is fixed to the end surface of the structure.

  However, in the fixing method using fasteners such as screws and bolts, it is necessary to prepare fasteners such as screws and bolts, and the cost required for fixing is extra, so the cost of the step elimination block (slope) itself can be reduced. In addition, since it takes time to fix, it is not possible to simplify and increase the efficiency of the entire work required to install the step elimination block (slope).

Furthermore, in the fixing method using fasteners such as screws and bolts, the types of structures on which the inclined portions can be arranged are limited to those that can be fixed using fasteners such as screws and bolts. It cannot meet a wide range of needs and applications.
Further, the step elimination block (slope) is required to improve the durability at the same time while reducing the cost. However, there is no known one that satisfies these two requirements at the same time.

  The present invention has been made to solve such problems, and its purpose is to respond to a wide range of needs and applications for step elimination, and it is possible to easily and efficiently eliminate steps in a short time. An object of the present invention is to provide a step elimination block having excellent durability at low cost.

In order to achieve such an object, the present invention is arranged on the base surface in order to eliminate a step formed by the base surface and the end surface of the structure when the structure is arranged on the base surface. A step elimination block that can be arranged along the end surface of the structure, and a gap intervention that extends from the step elimination portion and can be interposed in the gap between the base surface and the structure The step eliminating portion has a contact surface on which the end surface of the structure abuts and an end surface of the structure abuts on the contact surface when the step elimination portion is disposed along the end surface of the structure. In such a state, there is provided an inclined surface that is continuous downwardly from the upper end surface of the structure toward the upper base surface, and when the stepped portion is disposed along the end surface of the structure, The gap interposed portion interposed in the gap between the base surface and the structure is the base surface. By being sandwiched between the structure and the structure, the relative displacement between the stepped portion and the end face of the structure in the positional relationship where the end surface of the structure is in contact with the contact surface of the stepped portion is generated. In addition, the inclined surface of the step eliminating portion is maintained in a continuous state with a downward gradient from the upper end surface of the structure toward the upper base surface.
In the present invention, the height of the contact surface of the step eliminating portion is set in accordance with the height of the end surface of the structure.
In the present invention, the step elimination block is provided with a first grip surface that comes into contact with the base surface with a predetermined frictional force when the step elimination block is disposed on the base surface. A second grip surface is provided that comes into contact with the structure with a predetermined frictional force when sandwiched between the base surface and the structure.
In the present invention, an anti-slip is provided on the inclined surface of the step eliminating portion.
In the present invention, the step eliminating block is configured to have water resistance, corrosion resistance, and durability.

  According to the present invention, it is possible to meet a wide range of needs and applications for step elimination, and realize a low-cost and durable step elimination block that can easily and efficiently eliminate a step in a short time. be able to.

Sectional drawing which follows the XX line of FIG. The side view which shows the structure of the level | step difference elimination block which concerns on the Example of this invention.

Hereinafter, a step elimination block according to an embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in FIGS. 1 to 4, the step elimination block 2 of the present embodiment has the base surface 4 and the structure 6 when the structure 6 is placed (placed) on the base surface 4 (see FIG. 4). Is disposed on the base surface 4 in order to eliminate the step G (see FIG. 3) formed by the end surface 6s. This will be specifically described below.

  The base surface 4 can be assumed to be, for example, a road surface, the ground, a floor surface, and the structure 6 is, for example, a steel or resin (curing) floor plate, various mats, or the like. However, here, as an example, a steel path that is placed (placed) on the passage (base surface 4) is defined as a base surface 4 in a construction site where a worker and a work vehicle come and go. The floorboard is a structure 6 (see FIGS. 3 and 4).

  In such an embodiment, as shown in FIGS. 1A and 1B, the step eliminating block 2 includes a step eliminating portion 8 that can be disposed along the end surface 6s (see FIG. 3) of the structure 6. And a gap interposition part 10 that extends from the step elimination part 8 and can be interposed in a gap between the base surface 4 (see FIG. 4) and the structure 6.

  Here, when this is disposed along the end surface 6 s of the structure 6, the contact surface 8 a with which the end surface 6 s of the structure 6 abuts and the end surface 6 s of the structure 6 are abutted with the step eliminating portion 8. In contact with the contact surface 8a, there is provided an inclined surface 8b that forms a downward slope from the upper end surface 6s of the structure 6 toward the upper portion of the base surface 4 and continues.

  In such a configuration, the height H1 of the contact surface 8a of the step eliminating portion 8 is set in correspondence with the height H2 (see FIG. 3) of the end surface 6s of the structure 6. That is, the steel floorboard as the structure 6 is required to have strength (rigidity), durability, and the like according to various needs in its intended use and usage environment, and accordingly, the height of the end face 6s of the structure 6 is increased. The height H2 also changes in height. Therefore, as a technical scope of the present invention, it is preferable that the height H1 of the contact surface 8a of the step eliminating portion 8 can be arbitrarily set according to various needs.

  Here, for example, assuming that the height H1 of the contact surface 8a of the step eliminating portion 8 is set to coincide with the height H2 of the end surface 6s of the structure 6, in this case, the step eliminating portion 8 is structured. In a state of being arranged along the end surface 6s of the object 6, the inclined surface 8b of the step eliminating part 8 can be continuously formed with a downward gradient from the upper part of the end surface 6s of the structure 6 toward the upper part of the base surface 4. Therefore, the step G formed by the base surface 4 and the end surface 6s of the structure 6 can be completely wiped away (see FIGS. 3 and 4).

  In the above-described step elimination block 2 (see FIGS. 1A and 1B), the total height T (the height H1 of the contact surface 8a of the step elimination portion 8 and the thickness (high) of the gap interposition portion 10 are shown. And the total width L (the total length from the step eliminating portion 8 to the gap intervening portion 10), the inclination angle θ of the inclined surface 8b of the step eliminating portion 8, the entire width S, and the like. Is set according to the purpose of use, the environment of use, etc. of the level difference elimination block 2, and is not specifically limited here.

  In this case, in particular, the thickness (height) W of the gap interposition part 10 can be interposed in the gap between the base surface 4 and the structure 6, and the base surface 4 and the structure 6. It is preferable to set a dimension such that it is sandwiched between the base surface 4 and the structure 6 (in other words, a dimension that is sandwiched between the base surface 4 and the structure 6).

  According to such a level difference elimination block 2, when the level difference elimination part 8 is arranged along the end surface 6s of the structure 6, the gap interposition part 10 interposed in the gap between the base surface 4 and the structure 6 is provided. By being sandwiched between the base surface 4 and the structure 6, the step eliminating portion 8 and the structure 6 in the positional relationship in which the end surface 6 s of the structure 6 abuts against the contact surface 8 a of the step eliminating portion 8. The relative displacement with respect to the end surface 6s of the structure 6 is prevented, and the inclined surface 8b of the step eliminating portion 8 is continuously descending from the upper end surface 6s of the structure 6 toward the upper portion of the base surface 4. Is maintained.

  As described above, according to the step elimination block 2 of the present embodiment, the step elimination portion 8 that can be disposed along the end surface 6 s of the structure 6, and the base surface 4 and the structure 6 are extended from the step elimination portion 8. Since it can be configured only by having the gap interposition part 10 that can be interposed in the gap, and there is no need for conventional fasteners such as screws and bolts, the manufacture of the step elimination block 2 itself Cost can be significantly reduced compared to the conventional one.

  Further, according to the step elimination block 2 of the present embodiment, positioning of the contact surface 8 a of the step elimination portion 8 with respect to the end surface 6 s of the structure 6 (that is, prevention of displacement) is performed by using the step elimination portion 8 as the base surface 4. Since it is realized only by a simple process of interposing (i.e., sandwiching) between the structure 6 and a conventional fastener such as a screw or a bolt is not required, the end face 6s of the structure 6 is not required. The labor and time required for positioning (preventing misalignment) of the contact surface 8a of the step eliminating portion 8 can be greatly reduced as compared with the conventional one. Thereby, a level | step difference can be eliminated efficiently in a short time.

  Further, when positioning the contact surface 8a of the step eliminating portion 8 with respect to the end surface 6s of the structure 6 (preventing misalignment), if a fastener such as a screw or a bolt is required as in the prior art, the inclined portion 8b is disposed. Although the types of possible structures 6 are limited to those that can be fixed with fasteners such as screws and bolts, according to the step elimination block 2 of the present embodiment, conventional screws and bolts such as Since no fasteners are required, it is possible to meet a wide range of needs and applications for step elimination regardless of the type (for example, material) of the structure 6.

  Further, according to the step elimination block 2 of the present embodiment, since it has an extremely simple structure consisting of only the step elimination portion 8 and the gap interposition portion 10, the degree of freedom in selecting the material for forming the step elimination block 2 is greatly increased. Can be spread. Thereby, the level | step difference elimination block 2 can be comprised with water resistance, corrosion resistance, and durability.

  Furthermore, according to the step elimination block 2 of this embodiment, an external load is applied to the end surface 6s by interposing the inclined surface 8b of the step elimination unit 8 between the end surface 6s of the structure 6 and the base surface 4. Therefore, it is possible to prevent early deterioration of the end face 6s (and consequently the structure 6 itself).

  Here, in this embodiment, the step elimination block 2 has a first grip surface 2g (see FIG. 2) that contacts the base surface 4 with a predetermined frictional force when it is disposed on the base surface 4. Is preferably provided. In this case, the first grip surface 2g is formed on the back surface of the step eliminating block 2 (that is, the entire surface extending from the back surface 8t of the step eliminating unit 8 and the back surface 10t of the gap interposed unit 10), for example By forming a plurality of grooves, dents, protrusions, protrusions, or the like in the combination direction, it is possible to construct a grip (non-slip) structure in which undulations and unevenness are provided in the vertical and horizontal (crossing) directions.

  Further, in the present embodiment, the gap interposed portion 10 has a second grip surface 10g that comes into contact with the structure 6 with a predetermined frictional force when the gap is interposed between the base surface 4 and the structure 6. (See FIGS. 1 (a), (b) and FIG. 3). In this case, the second grip surface 10g is provided with a plurality of grooves, depressions, protrusions, protrusions, or the like on the surface 10f of the gap interposition part 10 in, for example, a vertical and horizontal direction, a crossing direction, or a combination direction thereof. It can be constructed as a grip (non-slip) structure with undulations and irregularities in the (crossing) direction.

  According to the step elimination block 2 of this embodiment provided with such a grip (slip prevention) structure, when the step elimination portion 8 is arranged along the end surface 6s of the structure 6, the gap interposition portion 10 and the base surface 4 are disposed. In a state of being sandwiched between the structure 6 and the second grip surface 10g of the gap interposed portion 10 can be brought into contact with the structure 6 with a predetermined frictional force, The first grip surface 2g can be brought into contact with the base surface 4 with a predetermined frictional force.

  As a result, in the positional relationship in which the end surface 6s of the structure 6 is in contact with the contact surface 8a of the step eliminating portion 8, the relative displacement between the step eliminating portion 8 and the end surface 6s of the structure 6 is further generated. It can be surely prevented. As a result, the inclined surface 8b of the step eliminating portion 8 can be maintained for a longer period in a continuous manner with a downward gradient from the upper end surface 6s of the structure 6 toward the upper portion of the base surface 4.

  Moreover, in this embodiment, it is preferable to provide the anti-slip | skid 8g to the inclined surface 8b of the level | step difference elimination part 8. FIG. In this case, the anti-slip 8g is formed in the inclined surface 8b of the step eliminating portion 8 by applying a plurality of grooves, dents, protrusions, protrusions, or the like in the vertical / horizontal direction, the crossing direction, or a combination direction thereof. ) It can be constructed as a grip structure with undulations and irregularities in the direction.

  Thereby, when the worker or the work vehicle is coming and going, the slip stopper 8g of the inclined surface 8b can be brought into contact with the shoe sole of the worker or the tire of the worker with a predetermined friction force, for example. Safe and reliable transportation of workers and vehicles is possible.

  In the above-described embodiment, as the slip stopper, the first grip surface 2g (see FIG. 2) is provided on the back surface of the step elimination block 2, and the second grip surface 10g (FIG. ), (b), see FIG. 3). However, the first grip surface 2g and the second grip surface 10g are not necessarily required. For example, the back surface of the step elimination block 2 and the gap interposition portion 10 are provided. Either one or both of the surfaces may be a flat surface without unevenness (that is, a flat surface).

<Embodiment of the present invention>
As a specific embodiment of the present invention, for example, as shown in FIG. 5, each of the inclined surface 8 b of the step eliminating portion 8 and the surface 10 f of the gap interposed portion 10 is extended along the longitudinal direction thereof. By providing a plurality of protrusions Pg, it is possible to assume the step elimination block 2 in which the above-described second grip surface and anti-slip are configured. In this case, the number, interval, and shape of each protrusion Pg can be arbitrarily set according to the use of the step elimination block 2. In particular, the ratio of the base width to the height is 2 for the shape. It is preferable that the protrusions Pg have a triangular cross section so as to be pair 1.
