Description

The present invention relates to a connector and a structure having the connector.

When it is necessary to temporarily configure the boundary between the roadway and the construction area in road construction, etc., the boundary may be simply formed by previously installing a structure that can function as the boundary. For example, there is a method in which a structure such as a precast concrete block formed in the shape of a wall or a heavy object formed mainly of a steel frame is continuously installed at the boundary portion. In this case, it is necessary to connect adjacent structures so that these structures do not move when a car or the like collides.

In order to achieve such a connection, for example, as a connector for connecting a precast type concrete block, at least one male-side connector fixed to the end surface of the first precast foundation and the first precast foundation are used. At least one female-side connector fixed to an end surface of the second precast foundation to be connected, wherein the male-side connector is a joint surface inclined so that its tip side is upward in the longitudinal direction of the foundation. It has been proposed that the female connector has a joint surface that comes into close contact with the joint surface by overlapping the male connector from above (Patent Document 1). 1).

In such a connection structure of the precast foundation, after the first precast foundation is installed at a predetermined place, the female connector connected to the end surface of the second precast foundation is connected to the male side of the first precast foundation. If the tools are installed so as to overlap with each other from above, the first and second precast foundations are connected to each other, and there is an effect that a state in which they do not move relative to each other is formed.

However, since the precast foundation and the protective fences are very heavy, the female connector attached to the end surface of the second precast foundation is different from the male connector on the first precast foundation side. There is a problem in that it is very difficult to install them so that they overlap each other. On the other hand, in the above-described precast connection structure, it is possible to regulate the adjacent structures by the joining surface inclined in the longitudinal direction, but regulate the displacement in the horizontal direction at right angles to the longitudinal direction. There is no means, and there is a problem that a fairly skilled crane operation is required to guide the deviation to be small. In the worst case, it is necessary to manually correct it and prevent the deviation. In particular, there was a problem in that there is a considerable risk when the correction is performed manually.

The embodiments and the drawings described below exemplify a part of the embodiments of the present invention, are not used for the purpose of limiting these configurations, and are appropriate within a range not departing from the gist of the present invention. Can be changed. In the following embodiments, the case where a protective fence is formed using a precast concrete block as the structure 200 will be described as an example, but the structure according to the present invention is not limited to this, and can be used on a road surface. It is applicable as long as it can be installed, and is not particularly limited to the precast concrete block. In the detailed description of the invention and the claims, the upper surface, the lower surface, the front surface, the back surface, and the end surface respectively indicate the directions of arrows in FIGS. 1 and 3.

FIG. 1 shows a state in which two structures 200 having the connecting tool 100 according to the embodiment are connected, FIG. 2 shows a connecting method, and FIG. 3 shows the connecting tool 100. As shown in FIG. 2, the structure 200 according to the present embodiment slides from above with respect to the connector 100 of the structure 200 already set and the connector 100a of the structure 200a to be connected. It is to be fixed as.

As shown in FIG. 1, the connecting tool 100 is provided on the end surfaces 201 on both sides of a structure installed on a road, for example, a structure 200 that forms a boundary, and by connecting the connecting tools 100 with each other, Adjacent structures 200 are connected and arranged to form a long boundary.

As shown in FIGS. 1 and 3, the connecting tool 100 is formed by projecting outward from an end surface 201 of the structure 200 and an attachment fixing portion 10 for attaching to the structure 200, and the connecting tool 100 is disposed adjacent to the fixing surface 10. It has a hook portion 20 having a function of connecting with. The fixing part 10 for mounting is not particularly limited, and for example, as shown in FIG. 4, a mounting hole 11 is provided as the fixing part 10 for mounting in the coupling tool 100, and the mounting surface 10 is attached to the end surface 201 of the structure 200. It may be directly attached from the outside using a bolt or the like. In short, the structure is not particularly limited as long as it can be attached to the structure 200 with such strength that it does not come off. In this embodiment, a structure in which a part of the connector 100 is embedded in the structure 200 is adopted. Details will be described later.

As shown in FIG. 2, the hook portion 20 is provided on the other end (an end portion on the opposite side) of the attachment fixing portion, and extends from the end surface 201 of the structure 200 when attached to the structure. And is formed into a hook shape that is folded back so as to have a J shape in a top view. An upper end side slidable surface 23 formed in a taper shape is provided from the upper end 21 of the hook portion 20 to the inner side surface 22. Further, similarly to the lower end 24 side of the hook portion 20, as shown in FIG. 5, a lower end side slidable surface 25 formed in a tapered shape from the lower end 24 to the inner side surface 22 is provided. The upper end side slidable surface 23 and the lower end side slidable surface 25 slide on the slanted surface even when the connecting members 100 are slightly displaced from each other when lowering the adjacent structure 200. It is provided to correct the position. It is not always necessary to provide both the upper end side slidable surface 23 and the lower end side slidable surface 25, and either one may be provided. Further, it is preferable that the upper end side slidable surface 23 and the lower end side slanted surface 25 have the same angle. By providing the structures 200 at the same angle, it is easy for the structures 200 adjacent to each other to come into contact with each other on the surface when they are dropped from above, and damage to the connector 100 can be reduced. As shown in FIG. 6, the hooks 20 to be connected have gaps 26 therebetween when the structures 200 are fitted to each other so that the hooks 20 can be installed on a road with a slight curve or a slope. It may be formed to be provided. The gap 26 is not particularly limited, but it is preferable to provide the gap 26 that can be installed at an angle of 5% or more in both longitudinal and transverse traverses.

Further, a positioning plate portion 27 extending in a standing plate shape may be provided on the end face side of the hook portion 20. The positioning plate portion 27 is attached vertically to the hook portion 20. As shown in FIG. 6, the positioning plate portion 27 is fitted into the groove 202 formed on the structure 200 side. In order to make it easier to fit in this case, the positioning plate portion 27 is formed such that the upper portion and the lower portion are thin and the center or the vicinity of the center is thick, as shown in FIG.

The structure 200 is a heavy object that forms a boundary on the road surface. Generally, it is formed in a standing plate shape so as to form a wall surface, but its form and material are not particularly limited. In this embodiment, a so-called precast type concrete block is used, and the base bottom side is thick, and the upper side is formed by using a synthetic guard fence of a thin type. It may be a rigid protective fence or a flexible protective fence, and its form is not particularly limited.

Further, in the structure 200 according to the present embodiment, as shown in FIG. 2, the vertical center or the vicinity of the vertical center of the end face 201 to which the connecting tool 100 is attached is formed to project toward the upper end or the lower end. By adopting such a configuration, it is possible to reduce the possibility that the upper side or the lower side of the end surface of the precast concrete block will collide and be damaged when it is slid up and down. In addition, it is possible to easily confirm the position of each connecting tool 100 when the structure 200 is fitted while being lowered. Further, in order to prevent collision of the upper side or the lower side of the end surface of the precast concrete block, a notch 203 may be provided at the upper end.

Further, as described above, the groove 202 into which the positioning plate portion 27 is inserted is formed in the end surface 201 of the structure 200. The groove 202 is formed wider than the positioning plate portion 27, and is formed so as to become wider as it goes upward. Therefore, it is easy to insert the positioning plate portion 27 into the groove 202, and after the insertion, the position of the connector 100 is corrected as it moves downward along the groove 202, and the other connector automatically. It becomes easy to combine with 100. Further, even after the installation, the horizontal angle between the structures 200 is regulated, and the joint between the structures 200 is prevented from being bent when an automobile or the like collides.

With respect to the structure 200 configured in this way, the connector 100 is attached to both ends of the structure 200 so as to be rotationally symmetrical when the structure 200 is horizontally rotated. As shown in FIG. 8, the attachment method is such that it is embedded in the structure 200 while being fixed to both ends of the connecting bar 80. Therefore, the connecting members 100 at both end portions are fixed in the concrete together with the connecting bar 80, so that they are firmly attached.

The connector 100 and the structure 200 having the connector 100 manufactured as described above are installed as follows. First, the structure 200 having the connector 100 is installed on the road surface where the boundary is to be constructed. At this time, as shown in FIG. 7, a non-slip plate 90 made of a non-slip rubber plate or the like may be arranged between the structure 200 and the road surface. As shown in FIG. 2, with respect to the installed structure 200, a structure 200a scheduled to be adjacently arranged is lifted by a crane or the like, and while checking the position, the structure 200a is moved so as to be adjacent to the installed structure 200. .. Then, the positioning plate portion 27 of the connector 100 is suspended so as to be inserted into the groove 202 of the structure 200. As a result, the position of the suspended structure 200a is corrected as the positioning plate portion 27 descends in the groove 202. When the suspended structure 200a is lowered as it is, it is automatically corrected to a position where the hook portions 20 of the connector 100 are fitted to each other. At this time, in the initial stage of fitting, even if the connecting tools 100 are slightly deviated from each other, the upper end side slidable surface 23 is formed in a tapered shape from the upper end 21 and the lower end 24 of the hook portion 20 toward the inner side surface 22, and By the lower end side slidable surface 25, the slanting surface 25 is slid down to be naturally corrected to a position where the connecting tool 100 fits while sliding. The connector 100 is fitted and connected as shown in FIG. 8 simply by descending as it is. As described above, according to the structure 200 according to the present embodiment, the position is naturally adjusted only by lowering the positioning plate portion 27 along the groove 202, so that the adjacent structure 200 is connected. Cheap. Further, since the relative positions of the connected structures 200 are fixed to each other by the connecting tool 100, the positioning plate portion 27, and the groove 202, even if an automobile or the like collides with the structure 200, the structures 200 are mutually separated. The possibility of coming off can be reduced.

It is needless to say that the present invention is not limited to the above-described embodiments and can be implemented in various modes within the technical scope of the present invention.

In the above-described embodiment, the hook portion 20 is formed to have a rectangular shape in a top view, but it may be formed to have a curved shape as shown in FIG. 9. Even if such a form is adopted, the same effect can be obtained.

Further, in the above-described embodiment, a shielding plate 95 that can hide the connector 100 may be attached as shown in FIG. 10 so that the connector 100 cannot be visually recognized. By attaching the shielding plate material 95, it is possible to create a boundary having an excellent aesthetic appearance.

As shown in the above-mentioned embodiment, it can be industrially used for producing a simple protective fence on a road surface.
