Description

  The present invention relates to a spacer that is interposed between concrete products to keep the interval between the concrete products when the concrete products are stocked or transported.

  For example, this type of spacer has a linear plate shape as disclosed in Patent Document 1 below, and both ends serve as connecting portions so that a plurality of spacers can be connected. One connecting portion is a thin plate-like body, and the other is a hollow portion into which the plate-like body is inserted in the axial direction. An engagement convex portion is formed on the plate surface of the plate-like body, and an engagement hole is formed in the hollow portion. When the plate body is inserted into the hollow portion, the engagement convex portion engages with the engagement hole and the connection portion is removed. It becomes difficult.

  When interposing between concrete products stacked in the vertical direction, the spacer may be a simple plate, but when interposing between concrete products arranged in the horizontal direction, the spacer is attached to an axis at one end of the spacer. By providing an engaging portion extending in a direction perpendicular to the direction and hooking the engaging portion on the upper surface of the concrete product and interposing the spacer between the concrete products, the spacer is prevented from falling.

Japanese Patent No. 3007028

  Since the spacer of Patent Document 1 is a straight plate, a plurality of spacers must be interposed at one location between concrete products, and the plurality of spacers interposed at one location is Since they are not connected to each other, the positional deviation is likely to occur, and the spacer interposing work is complicated.

  An object of the present invention is to facilitate the work of interposing a spacer between concrete products.

  The present invention is a spacer that is interposed between concrete products and maintains the space between the products, and has a bar shape, both ends are high, and a center part hangs down on both ends of the main body, The spacer is characterized in that a latching portion projecting in a perpendicular direction is formed.

  The shape in which both ends are high and the central portion hangs down is, for example, a shape that is substantially U-shaped, V-shaped, or W-shaped.

  The spacer of the present invention is not a simple linear shape, but is a shape that spreads in a plane, so that the concrete product can be stabilized only by inserting one between each part of the concrete product. Can be arranged.

  In addition, since the spacer body of the present invention is rod-shaped, material can be saved significantly compared to conventional plate-shaped spacers.

  The shape of the latching portion is desirably a columnar shape or a saddle shape. When the spacer of the present invention is used by interposing between concrete products arranged in a horizontal direction, the spacer is prevented from falling by hooking the latching portion on the upper surface of the concrete product. . When a plurality of concrete products arranged in the horizontal direction are stacked in this way, the latching part becomes a spacer between the upper and lower concrete products, and the latching part is shaped like a cylinder or a bowl, so that The contact area with the product surface is reduced, and the color unevenness of the concrete surface with which the latching portion comes into contact can be minimized.

  The spacer of the present invention forms a plurality of bulges at arbitrary intervals on the main body, and when the spacer is interposed in a concrete product, the bulge contacts the concrete product surface, and the main body itself contacts the concrete product surface You can avoid it.

  By doing in this way, the contact area of a spacer and a concrete product surface becomes very small, and the color nonuniformity on the surface of a concrete product can be suppressed to the minimum.

Since the spacer of the present invention only needs to be interposed between one portion of the concrete product, the operation of inserting the spacer between the concrete products can be facilitated.
In addition, since the spacer body of the present invention is rod-shaped, material can be saved significantly compared to conventional plate-shaped spacers.

It is a front view of spacer 1 'of an Example.

1 to 7 relate to the spacer 1 of the embodiment.
The spacer 1 is formed by integrally molding plastic by injection molding. As shown in FIGS. 1 and 3, the main body 2 is shaped like a rod having a square cross section, and has a frontal shape that is generally U-shaped with both ends being high and the center portion depending. At both ends of the main body 2, there are formed latching portions 3 projecting in a direction perpendicular to the surface to which the main body belongs (direction passing through the front and back in FIG. 1). In the case of the present embodiment, the shape of the latching portion 3 is a substantially bowl shape (cross-sectional semicircular shape).

  The main body 2 is formed with bulging portions 4 at appropriate intervals. In the case of the present embodiment, the bulging portion 4 has a spherical shape. The shape of the bulging portion is not limited to a spherical shape, and may be a disc shape, a square plate shape, a polygonal plate shape, or the like. At both ends of the lower side of the main body 2, corner portions 5 having a large cross-sectional area are formed in order to increase rigidity.

4 and 5 show a case where plate-shaped concrete products 6 such as side groove lids are arranged in the horizontal direction and the spacer 1 is interposed therebetween.
Since the spacer 1 is hooked on the upper surface of the concrete product 6, the spacer 1 is not likely to fall.
As shown in FIG. 5, the spacer 1 is not a simple linear shape, but a U-shape having a planar extension, so that one spacer is interposed between concrete parts. Just put the concrete products in a stable state. For large concrete products, a plurality of spacers 1 can be interposed at one place.

  As shown in FIGS. 4 and 5, when the spacer 1 is interposed between the concrete products, the bulging portion 4 comes into contact with the concrete product surface, and the main body 2 itself does not contact the concrete product surface. For this reason, the contact area between the main body 2 and the concrete surface becomes extremely small, and the uneven color of the concrete surface can be minimized.

  FIG. 6 shows the concrete products 6 arranged in the horizontal direction as shown in FIG. In this case, the latching part 3 becomes a spacer between the upper and lower concrete products. Since the shape of the latching portion 3 is a bowl shape, the contact area between the latching portion and the concrete product surface is reduced, and the color unevenness of the concrete surface with which the latching portion comes into contact can be kept small.

  FIG. 7 shows a case where the concrete products 6 are stacked in the vertical direction and the spacer 1 is interposed between the concrete products. Thus, the spacer 1 can also be used when stacking concrete products in the vertical direction.

  FIG. 8 is a front view of a spacer 1 ′ according to another embodiment. The spacer 1 has the same configuration as the spacer 1 except that the front shape of the main body 2 is different. In this case, the front shape of the main body 2 is substantially W-shaped. As described above, the front shape of the main body may be any shape as long as both ends are high and the central portion is hung down. Specifically, the main body may have a U shape, a V shape, a W shape, or the like.
