Description

Buried Anchor Bolt Fixture {FIXING CONSTRUCTION OF ANCHOR BOLT FOR LAYING}

The present invention relates to an anchor bolt fixture that is installed on a concrete foundation for the installation of a structure, and more particularly anchors that can maintain a constant spacing and height between a plurality of anchor bolts to be supported and significantly reduce the manufacturing cost The structure of the bolt fixture.

In general, anchor bolts are bolts that connect the foundation of concrete or reinforced concrete, such as the base of steel structures or wooden pillars or girders of bridges, buried most of their length into the foundation and part of the projections over the foundation surface. By inserting the upper structure into the nut to be fixed in this way, the structure is firmly fixed to the foundation and thus serves to prevent vibration and shaking of the structure and to prevent it from falling down or falling down by the impact.

In addition, such an anchor bolt is to bend the end of the buried portion or to install a separate anchor plate so as not to fall off from the foundation of the buried portion or to use a separate barbed bolt to bury.

These anchor bolts are mainly used for fixing the vibrating machine tool, or mainly for the purpose of fixing the street lamps or display panels on the side of the road, and in addition to the rigid fixing of various steel structures.

In addition, the anchor bolt may be buried in a buried part, that is, a single individual in concrete, but most of the anchor bolts are prepared to maintain a distance of equal intervals or unequal intervals by using one pair of four to have a rectangular structure in plan view. After the foundation surface is embedded, this preparation work is a separate connecting rod (101,101 ') between each anchor bolt (100,100') in a vertically installed state of the plurality of anchor bolts (100,100 ') as shown in FIG. The plurality of anchor bolts 100 and 100 'are fixed to each other by the connecting rods 101 and 101' to have a predetermined interval, and the anchor bolt fixing body prepared in advance is moved to the site by means of a conveying means. The lower part is to install concrete buried.

However, such a conventional anchor bolt support structure is made by welding work, not only takes excessive work time, but also uses 8 to as many as 12 connecting rods of metal to unnecessary overuse of raw materials and increase in weight. There was a problem inconvenient transportation and management.

In addition, the anchor bolt support structure is inconvenient to be equipped with a welding device in the handling company and the site, the distance or height of the completed anchor bolt by adjusting the separation distance and height between each anchor bolt by the welding operation is one Not to increase the defective rate, as well as after the concrete is cured by embedding such a bad body there is a problem that can not be combined with the structure can not be stable structure support.

The present invention has been proposed to improve the problems of the conventional anchor bolt support, by providing an anchor bolt fixture structure that can be fixed in the center so that the spacing and height between anchor bolts can be maintained the same during manufacturing The purpose is to reduce the defective rate of the product.

In addition, another object of the present invention is to improve the workability and workability according to the manufacturing by fixing the anchor bolt can be made in the assembly rather than the conventional welding.
