Description

  The present invention relates to a civil or architectural block used for standing structures such as fences, safety fences, retaining walls, and the like, and a fixing method thereof, and more particularly, to a block having improved standing stability and a fixing method thereof.

  Conventionally, a block made of concrete for civil engineering or construction is produced in a factory, and this is transported to the site, and installed and fixed on the site. As a fixing method, it is common to fix the block by a method in which a reinforcing bar is stretched around the lower part of the block, and then raw basic concrete is filled and the lower part of the block is filled together with the reinforcing bar.

  However, in the above conventional block fixing method, the raw concrete is filled into the hardened concrete constituting the block, and therefore the adhesive force between the hardened concrete and the raw basic concrete is weak. Therefore, the bottom concrete and the foundation concrete that fills the bottom of the block are not sufficiently connected, so the foundation concrete that fills the bottom of the block and the bottom of the block is easily separated by impact, vibration, etc., so sufficient stability and durability for the fixed block Sex was not obtained.

  In view of the various problems with the conventional block, the present inventor has developed a block having improved stability and durability, and a fixing method thereof, as a result of extensive research.

  The block according to the present invention is a block having a vertical wall portion, wherein a vertical reinforcing bar is arranged on the vertical wall portion in the block, and the upper portion of the block is supported on the vertical reinforcing bar from the outside of the vertical wall portion. It is characterized by having a coupling structure for connecting the two.

  Further, as a configuration of the block according to the present invention, in a block composed of a vertical wall portion and a base portion provided at a lower portion of the vertical wall portion, a bent reinforcing bar extending from the vertical wall portion to the base portion is arranged in the block, A configuration in which a vertical reinforcing bar is attached to the bending reinforcing bar in the vertical wall portion and a connecting structure for connecting a block upper supporting reinforcing rod that supports the upper portion of the block from the outside of the vertical wall portion to the vertical reinforcing bar may be provided. .

  By configuring as described above, it is possible to easily connect a block upper support reinforcing bar, which improves the installation stability of the block and reduces the influence of the block upper portion to impact and vibration, to the vertical wall portion of the block. Convenient. In addition, if the connecting means capable of connecting the block upper support reinforcing bar is provided, the block upper support reinforcing bar can be easily connected to the block. If the block upper support reinforcing bar is connected, the height of the vertical wall portion is increased. The greater the effect, the greater the effect of supporting the upper part of the block, which is extremely advantageous.

  Furthermore, as a configuration of the block according to the present invention, in a block composed of a vertical wall portion and a base portion provided at a lower portion of the vertical wall portion, a bent reinforcing bar extending from the vertical wall portion to the base portion is arranged in the block, It is good also as a structure provided with the connection structure for connecting the block lower part supporting reinforcement which supports the lower part of a block from the base part outside to the bending reinforcement in a base part.

  With this configuration, it is possible to easily connect the block lower support reinforcing bar to the block base to improve the installation stability of the block and reduce the influence of the block lower part on impact and vibration. Convenient.

  Furthermore, as a configuration of the block according to the present invention, in a block including a vertical wall portion and a base portion provided at a lower portion of the vertical wall portion, a bent reinforcing bar extending from the vertical wall portion to the base portion is arranged in the block. , Provided with a connecting structure for connecting the lower part of the block supporting the lower part of the block from the outside of the base part to the bent reinforcing bar in the base part, and further, a vertical reinforcing bar is attached to the bent reinforcing bar in the vertical wall part, It is good also as a structure provided with the joint structure for connecting to the said vertical reinforcing bar the block upper part supporting reinforcing bar which supports the upper part of a block from the vertical wall part outer side.

  By configuring in this way, it is possible to easily connect the block upper support rebar which improves the installation stability of the block and reduces the influence of the block upper part on impact and vibration to the vertical wall part of the block, It is convenient because it can be easily connected to the base part of the block to improve the installation stability of the block and reduce the influence of the lower part of the block on impact and vibration. . Moreover, if it has the joint end which can connect a block upper support reinforcement and a block lower support reinforcement easily in this way, each support reinforcement can be easily connected to a block, and if each support reinforcement is connected to a block, This is very advantageous because the stability and durability of the block is significantly increased.

  Moreover, as a structure of the block which concerns on this invention, it is good also as a structure which provided the collar part in the base part width direction of the said block in the block which consists of a vertical wall part and the base part provided in the lower part of this vertical wall part.

  With this configuration, when the base portion is buried and fixed with foundation concrete, the foundation concrete and the flange portion are fitted together, and the base portion of the block meshes with the foundation concrete to be integrated and cannot be removed. Improves. In addition, even if rainwater or the like enters from a gap generated between the block and the foundation concrete, it is blocked by the heel part, so that weakening due to moisture intrusion can be prevented and durability is increased.

  Furthermore, as a structure of the block which concerns on this invention, it is good also as a structure which provided the hole for concrete fillings in the base part with respect to said block.

  With this configuration, when the block is installed and the lower part of the block is hardened with foundation concrete, if the foundation concrete is filled from the concrete filling hole, the foundation concrete will enter the lower part of the base part. There is an advantage that a complete foundation can be solidified without any gaps.

  Moreover, as a structure of the block which concerns on this invention, in the block which has a vertical wall part, it is good also as a structure which provided the horizontal groove in the width direction edge part of the top part of a vertical wall part, and provided the vertical hole in the appropriate location in this horizontal groove.

  By configuring in this way, when the blocks are arranged in the width direction, the U-shaped rebar is inserted so as to straddle the vertical hole in the lateral groove of each adjacent block so that the U-shaped rebar is buried. If the vertical holes and the horizontal grooves are filled with concrete, each block can be fixed in the width direction, so that the stability of the block in the standing state can be improved and collapse can be prevented.

  In the block fixing method according to the present invention, a bent reinforcing bar extending from the vertical wall portion to the base portion is arranged in a block including a vertical wall portion and a base portion provided at a lower portion of the vertical wall portion. A vertical reinforcing bar is attached to the bent reinforcing bar, and a block having a coupling structure for connecting a block upper supporting reinforcing bar that supports the upper part of the block from the outside of the vertical wall portion is erected to the vertical reinforcing bar. After connecting the block upper support reinforcing bar to the vertical reinforcing bar from the outside of the vertical wall, the block upper support reinforcing bar is embedded together with the base portion of the block by filling the basic concrete, and the block is fixed.
