Such a basic block is convenient because it can be used in common for various devices having different sizes and positions of legs, and the devices can be easily installed. Such a basic block is disclosed in the following patent document, for example. In these basic blocks, the groove is made of a mold material such as aluminum embedded in the block surface.
Japanese Patent Laid-Open No. 11-230491 Japanese Utility Model Publication No. 49-89560 Japanese Utility Model Publication No. 2-13921 Japanese Utility Model Publication No. 4-3198 Design Registration No. 1166052

  The conventional basic block described above has the following problems. That is, when a force to fall is applied to the equipment due to an earthquake or the like, the force acts on fixing means such as a bolt. At that time, the force (pull-out force) acting on the bolt or the like is received only by the mold material constituting the groove, and an excessive stress is generated in the mold material. Vending machines, in particular, are quite heavy when combined with the weight of the main unit and the product weight, so the conventional foundation block was extremely fragile when fixing such equipment during an earthquake. .

  The present invention develops a basic block that has high strength against pulling force acting on fixing means such as bolts, can safely support even heavy equipment such as vending machines, and is easy to install equipment. Is made as an issue.

The present invention relates to a head groove having a width that allows a bolt head to slide and prevents rotation of the bolt head, and a washer plate formed in the upper portion of the head groove and inserted into the bolt having a wider groove width than the head groove. And a washer groove formed at the upper part thereof , the lowermost part being narrower than the head groove and the washer groove, and the bolt shaft part being slidable and the upper part being open on the upper surface of the foundation block A bolt groove having at least one end opened in the outer peripheral portion of the block, the head groove and the washer groove of the bolt groove are embedded with a metal or resin extrusion molding material, It is an installation foundation block of a vending machine or the like characterized in that all or part is formed of a concrete surface by die cutting .

  A bolt fitted with a washer plate is inserted from one end of the bolt groove opening, and is slid to be fastened and fixed with a nut screwed onto the bolt tip at an appropriate position. At this time, even if the nut is turned, the rotation of the bolt is prevented by the head groove so that it is not carried around. When a pulling force is applied to a bolt during an earthquake or the like, the force is transmitted from the bolt head to the washer to the upper wall of the washer groove. The shaft groove at the upper part of the washer groove has a narrower groove width than the washer groove, so that the force transmitted to the upper wall of the washer groove is received by the concrete of the foundation block and dispersed and transmitted in the concrete. Therefore, even if the bolt groove is made of a fragile aluminum or resin mold material, the tensile stress and bending stress generated in the mold material are small (almost compressive stress), the pulling force is received by the concrete, and the pulling strength is extremely increased. . For this reason, it is desirable to provide the washer groove at a sufficient depth inside the foundation block. The depth of the upper surface of the washer groove is preferably 40 mm or more.

  Reinforcing bars can be embedded along the washer groove directly above the washer groove. Here, “directly above” means that the distance (shortest distance) between the washer groove and the reinforcing reinforcing bar is within 10 mm. By providing the reinforcing reinforcing bars, the force transmitted from the washer groove to the concrete is dispersed in a wider range, and the pull-out resistance is further improved.

  All or part of the bolt groove can be formed by embedding a metal or resin extrusion molding material. The metal is suitably aluminum or an alloy thereof. The resin can be appropriately selected from vinyl chloride resin, polyethylene resin, polypropylene resin, and the like. Since almost no tensile stress or bending stress is generated in the bolt groove, a resin mold material with low cost can be used, and even when a metal mold material is used, the thickness can be made thinner than the conventional one.

  The head groove and the washer groove are preferably formed of the above-described mold material. This is because the upper washer groove is wider than the lower head groove, so it is difficult to form with concrete by die cutting. The shaft groove can be formed of concrete by die cutting. Thereby, the mold material can be reduced in size, and even if the head groove and the washer groove are formed in a deep portion inside the block, the mold material can be manufactured at a minimum mold material cost. Even in this case, the entire shaft groove does not have to be a concrete surface, and a part (only the lower part) can be formed of a mold material.

  An insert nut for connecting the foundation blocks or for lifting the foundation block can be planted on the surface or the outer periphery of the foundation block. When an overturning force is applied to the equipment during an earthquake, etc., even if the equipment and the foundation block are firmly fixed, if the weight of the foundation block is insufficient relative to the total weight of the equipment, the equipment There is a risk of falling. In order to avoid this, there are a method of connecting a plurality of foundation blocks to increase the weight of the foundation block, and a method of firmly fixing the foundation block to the ground or the like. If an insert nut is planted in the foundation block, a plurality of foundation blocks can be easily coupled by bolting the coupling plate to the insert nut. Moreover, by screwing the bolt of the lifting jig into the insert nut, the foundation block can be lifted by a lifting machine such as a crane, and can be moved and constructed. As such an insert nut, a known one can be used.

  A plurality of anchor holes penetrating the front and back surfaces can be provided through which anchors for mounting the foundation block on the ground or the like are inserted. The lower part of the anchor hole is an enlarged diameter part having a large diameter. The foundation block can be easily fixed to the ground or the like using the anchor hole.

  When fixing a foundation block to a concrete surface such as concrete pavement, first, a foundation block having anchor holes is laid on the concrete surface. In this case, it is desirable to apply an adhesive (such as cement containing an adhesive) between the concrete surface and the lower surface of the foundation block. Then, a hole is drilled in the concrete surface using the anchor hole as a guide. That is, a drill blade is inserted through an anchor hole to drill a concrete surface. At this time, the perforated scrap of concrete is stored in the enlarged diameter portion below the anchor hole. An anchor is set in this hole, and a foundation block is fixed by this anchor. Various well-known methods can be employed for fixing the anchor and the base block. For example, a nut can be fastened and fixed to the male screw of the anchor. Moreover, the kind of anchor is not specifically limited, A well-known expansion anchor, an adhesive fixed type anchor, etc. can be used.

  When fixing a foundation block to an asphalt pavement surface, first, a foundation block having an anchor hole is laid on the asphalt pavement. In this case, it is desirable to apply an adhesive (such as cement containing an adhesive) between the asphalt surface and the lower surface of the foundation block. Thereafter, using the anchor hole as a guide, an anchor bar having a sharp point at the lower end is inserted, and a thrust is applied to the anchor bar so as to enter the pavement surface (driving with a hammer, hammer drill or the like). Various well-known methods can be used to fix the anchor rod and the base block. For example, a head having an enlarged diameter is formed at the base of the anchor, and the base block can be pressed and fixed by the head. .
