Description

Technical Field [0001] The present invention relates to an apparatus and a method for manufacturing a light transmitting concrete block,

The present invention relates to a light transmitting concrete block, and more particularly, to a light transmitting concrete block, in which a light-permeable rod or tube is embedded in a concrete block to transmit light from one side to the other side of the concrete to realize a transparent or translucent concrete block To a light transmitting concrete block, an apparatus and a method for manufacturing the same.

Translucent concrete was introduced by the Hungarian architect Aron Losonczi in 2001 and was selected as "The 36th Inventions of the Year" in 2004 by America Time Magazine.

International Publication No. WO 03097954 discloses building blocks for materials such as cement mortars through which optical fibers pass light from one side of the block to the other.

This conventional translucent concrete block utilizes the role of the light passing through the optical fiber through the total reflection principle of light to transmit light to both ends of the optical fiber as it is. When a few hundred or several small optical fibers are arranged in a concrete block or a panel, And the shape or silhouette of the object can be transmitted to the opposite side through the light. In addition, since the optical fiber can be arranged in a bidirectional lattice not in one direction in a block or a panel, another object in the perpendicular direction can be expressed.

In a translucent concrete block, the optical fiber mixes about 4 to 10% of the total block volume and can be used for wall and roof structures of a few meters thickness because the optical fiber is hardly lost even to a distance of tens of meters in the longitudinal direction, This is because information can be transmitted. Depending on the amount of optical fiber used, not only can the shadow of the opposite object be clearly displayed, but also it can be expressed in various colors by using the characteristics of the optical fiber. In addition, since the concrete block exhibits a compressive strength of 30 MPa or more, it can be used as a construction structural material.

However, since the semitransparent concrete block using the optical fiber having such excellent functions requires a technique of arranging a fine-size optical fiber in a certain direction without being disturbed and keeping a straight line arrangement after curing, the workability is low, There is a problem that the use of architectural interiors and outdoor spaces is extremely limited due to the high price due to the use of the expensive optical fiber in the production process and the wide use of the whole industry is limited.

Korean Patent Laid-Open Publication No. 2011-0094061 discloses a cement mortar composite panel in which a through hole is formed in the cement mortar so as to penetrate in the width direction and a transparent material is filled in the through hole opening surface to have transparent characteristics.

However, the composite panel of the present invention is manufactured by arranging transparent materials in the form of a plate in a mold (molding mold) at regular intervals using a frame such as a movable rod, and placing the cement mortar in the mold, There is a problem that it is difficult and costly to manufacture because it is very difficult to arrange the transparent plates within the gap and to maintain the spacing.
