Description

  The present invention relates to a resin concrete block that can be used as a building material that substitutes for bricks.

  Conventionally, a brick block is generally constructed by stacking rectangular parallelepiped blocks and applying cement mortar or the like to the bonding surfaces between the blocks, thereby forming joints between the bricks.

  However, the walls and walls made by this method have a structural problem that they are vulnerable to lateral forces such as rolling earthquakes. In addition, the brick stacking work is complicated, such as leveling and soaking the bricks, and jointing with cement mortar requires the skill of the installer in order to make the joint width and depth clean. It was.

  Therefore, Patent Document 1 discloses a structure of a brick block that can be stably stacked having a concrete guard that forms a concave connection surface. However, compared with the conventional block, although this can increase the amount of concrete and mortar between bricks and can be stably connected, it is not reinforced in strength against the force from the side. . In addition, since the joints that are normally seen when loading bricks are not formed, the brick stacking operation can be simplified, but there is a problem that the atmosphere is different from the bricks having joints.

  Therefore, the present invention overcomes the drawbacks associated with conventional brick blocks, and is capable of seismic construction with sufficient strength against lateral force, and simplifies brickwork while keeping the joints clean. The issue is to provide resin concrete blocks.

  The present invention solves the above-described problem, and is a resin concrete block in which two side walls are arranged in parallel, and a plurality of partition walls are provided between the side walls to bridge and join both side walls. A notch is formed at the upper end of the outer surface of the side wall so that the side formed at the upper end of the side wall is convex in side view, and the resin concrete block is stacked at the side formed at both side walls and the lower end of the partition wall It is a resin concrete block characterized in that it is formed in a concave shape in side view that sometimes fits with the convex portion.

That is, since the resin concrete block of the present invention is formed in an uneven shape in a side view so that the upper and lower portions of each block are fitted when stacked up and down, it is also strong against the force from the side, In addition, by reinforcing the reinforcing bars in the vertical holes formed inside, it is possible to perform seismic construction that is not possible with conventional bricks. Furthermore, since no jointing work is required, anyone can easily perform construction, while the finish of the joints is neat and the construction period can be shortened to about one-third compared to ordinary bricks. Further, only a small amount of concrete is required for bonding between the blocks, and cement mortar for joints is unnecessary, so that raw materials can be reduced.

  Furthermore, by using resin concrete as a block material, it becomes possible to manufacture a high-strength product, and it is possible to increase the bonding strength of the parts to be fitted. And since it becomes possible to make the thickness of the whole block thin with such high intensity | strength, it can reduce in weight to about 40% compared with a normal brick, Therefore Laying work becomes easy.

  Hereinafter, embodiments of the resin concrete block of the present invention will be specifically described. Note that the present invention is not limited to these embodiments.

  1 is a perspective view of a resin concrete block according to the present invention, FIG. 2 is a front view thereof, FIG. 3 is a side view thereof, FIG. 4 is a plan view thereof, FIG. 5 is a bottom view thereof, and FIG. It is. In the figure, 1 is a block, 2 is a side wall, 3 is a partition wall, 4 is a decorative wall, 5 is a vertical hole, 21 is a notch, and 22 is a joint. As shown in each figure, the resin concrete block according to the present invention is provided with six partition walls 3 that face two side walls 2 in parallel and bridge and connect these side walls 2. Since the plurality of partition walls 3 are provided at predetermined intervals, a vertical hole portion 5 surrounded by the side walls 2 and the partition walls 2 is formed.

  And the resin concrete block which concerns on this invention is formed so that the side part formed by the side wall 2 and the upper end of the partition 3 may become convex as a whole, as shown in FIG. And the side part formed at the lower end of the partition 3 is formed to be concave. That is, the upper ends of the side wall 2 and the partition wall 3 are formed to have the same height except for a part on the outer surface side of the side wall 2, and the notch portion is formed so that a part on the outer surface side of the side wall 2 is one step lower than the partition wall 3. 21 is formed. In addition, the side walls 2 and the lower ends of the partition walls 3 are formed so that the side walls 2 protrude below the partition walls 3. Here, as shown in FIG. 7, when the blocks 1 are stacked, the cutout portion 21 is cut so that the convex upper end portion and the concave lower end portion formed by the side walls 2 and the partition walls 3 are fitted to each other. A notch dimension and a downward projecting dimension of the side wall 2 are formed. More specifically, the side wall 2 is formed so that the thickness thereof gradually decreases from the upper side to the lower side, and the thickness of the lower end portion thereof and the width of the notch portion 21 are substantially matched. On the other hand, the partition wall 3 is formed in a substantially trapezoidal shape in a side view, and the width of the lower end thereof is formed to be substantially equal to the total length of the width of the upper end and the thickness of the upper end of the side wall 2 excluding the notch 21. Has been. Thus, the convex upper end and the concave lower end are fitted to each other, so that the connecting portion between the blocks has sufficient strength against the force from the lateral direction.

  Further, two decorative walls 4 are formed on the outer surface of one of the side walls 2. The decorative wall 4 is projected in such a position and size that a horizontal joint 22 is formed at the lower end of the side wall 2 and a vertical joint 22 is formed at substantially the center and right end thereof. In addition, the upper end of the decorative wall 4 is provided to be the same height as the partition wall 3.

  FIG. 6 is a transverse central sectional view of the block 1. As shown in the figure, the partition wall 3 is formed so that its thickness gradually decreases from the upper part to the lower part. By forming the partition wall 3 in such a shape, the die-cutting operation at the time of molding becomes easy.

  The construction method of the resin concrete block of the present invention is as follows. First of all, the way of stacking blocks is the same as that of normal bricks, and the blocks are stacked upward while shifting horizontally by half a block (in the present invention, 1/4). At that time, it is only necessary to apply and stack concrete on the edges of the side wall 2 and the partition wall 3, and no cement mortar for joints is required, so material costs can be reduced. Further, the work time required for the conventional filling work can be reduced as it is. Moreover, if the vertical hole part 5 formed by the side wall 2 and the partition wall 2 is filled with concrete and reinforced with reinforcing bars, earthquake-proof construction with further improved strength is possible.

  The resin concrete block of the present invention constructed by such a method has a finish shown in FIG. In this way, the joints 22 formed in each block are connected, and the joints found in ordinary bricks are naturally formed.

  Since the resin concrete, which is the material of the resin concrete block of the present invention, is superior in strength to ordinary concrete, sufficient strength can be obtained even if the overall thickness is reduced. Therefore, the weight per block can be reduced to about 40% of the brick block, and the laying work becomes easy.

  Furthermore, as the above-mentioned concrete fine aggregate, the main component is calcium carbonate obtained by crystallizing the calcium component in hard water, which is generated with water hardness reduction in dam water and groundwater at the water treatment plant in Okinawa Prefecture. Use of pellets or molten slag discharged from an incinerator is preferable because it can protect resources by recycling and reduce manufacturing costs.

  In addition, the resin concrete block of the present invention pulverizes fine aggregate pellets, fires and colors the pulverized pellets, and mixes them with a colored molten slag at a certain ratio, so that natural stones with a shade or travertine tone Can be finished in the wind. The pulverized pellets may have a particle size of about 0.15 to 1.2 mm, and more preferably about 0.3 to 0.6 mm. When this is corrected to the coarse particle ratio (FM value), the preferred coarse particle ratio is 1.8 to 2.1. The molten slag preferably has a particle size of about 0.3 to 2.5 mm. The resin is preferably an epoxy resin type, an acrylic type, an acrylic resin type, an unsaturated polyester resin or the like, and an unsaturated polyester resin adhesive having a high transparency is particularly preferable.

  Table 1 shows an example of a blending ratio of resin concrete in which pulverized pellets and molten slag are used as fine aggregates and unsaturated polyester resin is used as the resin as the brick-like block material of the present invention. In addition, Table 2 shows an example of a blending ratio of resin concrete using pulverized pellets as fine aggregates and using an emulsion mixture as a resin.

  A resin concrete block formed by such a blend has a bending strength of about 5 to 6 times and a compressive strength of about 2 to 3 times that of general cement concrete.
