Description

  The present invention relates to a bevel block installed at the top of a block wall.

  Conventionally, a block fence or the like has been installed by covering a horizontal streak portion (top end) of the uppermost block to prevent penetration of rainwater and the like from the block lateral streak portion.

Conventionally, a technique using a mounting bracket (for example, refer to Patent Document 1), a technique using a mortar (for example, refer to Patent Document 2), and the like are known for fixing such a scabbard block to a block below the block. Yes.
JP-A-11-303461 JP-A-8-13647

  Among the above-mentioned conventional techniques, the latter technique using mortar and filling the mortar between the bottom surface of the block block and the horizontal cross section of the block below it does not require a mounting bracket and is excellent in versatility. However, there were the following problems to be solved.

  In this way, in the structure in which the slab block and the block below the mortar are combined, there is a difference in durability depending on the construction technique.

  That is, in general, a mortar filling recess is formed on the bottom surface of the bevel block, and when filling the mortar, the recess and a horizontal joint disposed on both sides of the recess are provided. The mortar is filled and adhered.

  However, depending on the installer, there is often a rough construction in which the mortar is not filled in the indented portion but is filled only in the lateral joint portions on both sides thereof.

  In this way, when the rough construction in which the mortar is filled only in the horizontal joints facing in the vertical direction between the block and the block below the block, the bonding strength decreases with time, When a child rides on a umbrella and plays with an external force on the umbrella block, the mortar peels off and the rattle or float occurs as a result of bearing the resistance against the external force only at the side joint. There was a problem that it might occur, and there was a problem that the scab block could fall off eventually.

  Therefore, the present invention provides a timber block and a block fence structure that can increase the bond strength between the timber block and the block below the mortar, and that can prevent the occurrence of poor construction. The purpose is to do.

  In order to achieve this object, the present invention is a bulkhead block which is installed at the upper end of a block ridge and is bonded by filling mortar between the horizontal bars of the block arranged below the block. A mortar groove for filling the mortar was formed on the bottom surface of the bevel block facing the horizontal stripes of the block.

  According to the configuration of the present invention, a plurality of mortar grooves are formed on the bottom surface of the bevel block, so that the contact area with the mortar in the bevel block is increased as compared to the prior art in which this mortar groove is not formed. The adhesion force and shearing force of the mortar increase, deterioration with time is less likely to occur, and even when an external force is input, this input can be dispersed to suppress mortar peeling.

  In addition, when mortar is filled between the bottom surface of the bevel block and the horizontal cross section of the block below it, a plurality of grooves for mortar are formed on the bottom surface of the bevel block. The effect of recognizing and enlightening the filling of the mortar with the mortar groove is obtained, and this makes it possible to suppress poor construction with an inappropriate mortar filling range.

  In addition to the above-described effects, in the invention described in claim 2, it is possible to improve the bonding strength by the mortar of the horizontal joint portion of the scab block. In addition, even when poor construction that does not fill mortar in the recesses between the horizontal joints is performed, the joint strength of the horizontal joints is higher than before, thereby preventing damage and falling off of the block An effect is obtained.

  In the invention according to the third aspect, the bonding strength in the indented portion can be improved.

  In the invention according to claim 4, since the mortar groove is formed in the longitudinal direction of the scab block, the drag force against the input in the width direction orthogonal to the longitudinal direction can be improved.

  In the invention according to claim 5, since the mortar groove is formed in a polygonal shape, a large adhesion area with the mortar can be secured, and the bonding strength can be further increased.

  In the invention according to claim 6, since the hollow portion is not exposed at the other end surface of the scab block, the appearance quality when arranged at the end portion of the block cage is excellent.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
