Description

  The present invention supports supporting objects such as pipes (for example, electric pipes, water supply / drainage pipes) and devices (for example, outdoor units of air conditioners) on the upper side of the installation surface such as the ground or the rooftop. Regarding the block and the manufacturing method thereof, in detail, an engaging portion that can be engaged with a connection object to the support object and / or a mounting portion on which the support object can be placed, or both of them are provided in the upper part. The present invention relates to a support block and a manufacturing method thereof.

  This type of support block needs a certain amount of weight in order to stably support the object to be supported. And, conventionally, as a support block, after pouring the ready-mixed concrete in a state where the metal dovetail groove forming member and the core material constituting the engaging portion are held at a predetermined position in the molding mold, Formed from solid concrete with dovetail forming member and core material embedded by removing the molding form (see Patent Document 1 below), or synthetic resin form with downward opening constituting the outer shell There is known a structure in which concrete and a formwork case are integrated by pouring ready-mixed concrete into the case and curing the structure (see Patent Document 2 below).

Japanese Utility Model Publication No. 3-123182 JP-A-8-42761

In the conventional support block, a curing period is required until the ready-mixed concrete poured into the mold form or the synthetic resin form case is cured, and the manufacturing period becomes long, and the material is limited to concrete. Therefore, the manufacturing cost is likely to increase.
Moreover, when cracks or the like occur in the hardened concrete, in the former case, since it peels off from the solid concrete constituting the formwork case, not only the appearance design is impaired, but also the function as a support block May be lost. In the latter case, concrete is placed in the formwork case, so that the appearance design can be maintained, but the cracked concrete pieces cannot be removed from the opening of the formwork case. The function of is reduced.

  The present invention has been made in view of the above circumstances, and its main problem is to reliably maintain the desired stable support function by weight while increasing the degree of freedom of material selection as a weight adjusting material. In addition, the present invention is to provide a support block manufacturing method and a support block that can increase productivity while simplifying the structure.

  According to a first characteristic configuration of the present invention, in the method for manufacturing a support block, an engaging portion that can be engaged with a connector for a support object, a placement portion on which the support object can be placed, or both of them are arranged at the top. A block main body formed with a storage chamber capable of storing a weight adjusting material loaded through an opening that opens to the outside is molded with resin, and the weight of the block main chamber is reduced during the molding cooling period of the block main body. The adjustment material is loaded, and a lid is attached to the opening, and the lid is held and held by the molding contraction force of the block body.

  According to the above configuration, since the housing body closed by the lid is formed in the block body of the resin molded product constituting the outline of the support block, and the weight adjusting material is loaded into the housing chamber, the weight adjusting material In addition to concrete, it is possible to use granular materials that do not require hardening treatment such as sand and gravel as they are, and it is possible to freely select an appropriate material considering productivity, handling, cost, etc. it can.

  Further, even when using concrete as the weight adjusting material, since it can be produced in advance in a form that can be loaded into the block body, it is possible to complete the support block at the completion of the molding of the block body, Even if cracking occurs in the concrete, the broken concrete piece does not fall off, and the stable support function by weight can be maintained.

  In addition, when the lid is attached to the opening of the block body, the lid is opened by using the molding shrinkage force of the block body during the molding cooling period of the block body formed of a resin material. Can be held and held by the part.

  Therefore, it is possible to reliably maintain the desired stable support function by weight while increasing the degree of freedom in selecting the material as the weight adjusting material, and to insert the weight adjusting material during the molding cooling period of the block body. Since only the body is mounted, productivity can be enhanced while simplifying the lid mounting structure.

A storage chamber for storing the weight adjusting material loaded through the opening opening to the outside is formed in the resin-molded block main body, and a lid for closing the opening in a state in which the weight adjusting material is loaded in the storage chamber is provided. The block body is held and held by the molding shrinkage force.

  According to the above configuration, since the housing body closed by the lid is formed in the block body of the resin molded product constituting the outline of the support block, and the weight adjusting material is loaded into the housing chamber, the weight adjusting material In addition to concrete, it is possible to use granular materials that do not require hardening treatment such as sand and gravel as they are, and it is possible to freely select an appropriate material considering productivity, handling, cost, etc. it can.

  Further, even when using concrete as the weight adjusting material, since it can be produced in advance in a form that can be loaded into the block body, it is possible to complete the support block at the completion of the molding of the block body, Even if cracking occurs in the concrete, the broken concrete piece does not fall off, and the stable support function by weight can be maintained.

  In addition, when the lid is attached to the opening of the block body, the lid can be held and held in the opening of the block body by using the molding shrinkage force of the block body formed of a resin material.

  Therefore, it is possible to reliably maintain the desired stable support function by weight while increasing the degree of freedom in selecting the material as the weight adjusting material, and to insert the weight adjusting material during the molding cooling period of the block body. Since only the body is mounted, productivity can be enhanced while simplifying the lid mounting structure.

  According to a third characteristic configuration of the present invention, in the support block, an engaging portion that can be engaged with a connection tool with respect to a support object and / or a placement portion on which the support object can be placed, or both of them are provided at the top. The block body of the resin molding is provided with a storage chamber for storing the weight adjusting material loaded through the opening opening to the outside, and a lid for closing the opening of the storage chamber is provided. The lid mounting dimension of the opening after molding shrinkage is such that the lid mounted in the opening can be held and held by the molding contraction force of the block body.
