Abstract

PURPOSE:To stick a machined sliding face block to a concrete main body precisely not to require post-machining without using a special insert member. CONSTITUTION:In addition to sticking a machined sliding face block 2 to the match face B of a concrete main body, an adhesive is injected and solidified into a gap A between an anchor bolt 3 buried in the match face of the concrete main body so that a head section with projections or recesses coupled in the axial direction of a screw or a groove is protruded and a hole with projections or recesses bored on the sliding face block side so that the anchor bolt head section can be inserted with a gap and coupled in the axial direction.

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure such as a frame or bed for a machine tool, etc., which is constructed by bonding blocks of metal material or the like to a concrete body.

0002

[Prior Art] Conventionally, when constructing a structure such as a frame or a bed using concrete as a base material, as shown in FIG. The sliding surface block 10 is then machined, or as shown in FIG.
4 is bolted. Alternatively, as shown in FIG. 4, a processed sliding surface block 105 may be bonded to the concrete body, or as shown in FIG. There are methods of fixing the moving surface block 107.

0003

[Problem to be Solved by the Invention] The methods shown in FIGS. 2 and 3 described in the prior art are expensive, and this is one of the reasons why structures based on concrete are not widely adopted. The method shown in Fig. 4 has a problem in terms of strength, particularly in that it is weak against force in the direction of F, and the method shown in Fig. 5 requires post-processing because the area where the bolt is tightened sinks, resulting in high costs. However, if the mounting hole is located on the sliding surface, there is a problem in that dirt and the like are likely to get caught. The present invention was devised in view of these problems of the conventional technology, and its purpose is to provide a highly accurate processed material that does not require post-processing without using special insert members. The purpose is to provide a structure in which sliding surface blocks and the like can be bonded to the concrete body.

0004

[Means for Solving the Problems] In order to achieve the above object, the adhesive structure of the structure according to the present invention provides a structure in which a block of metal material or the like is adhered to a concrete body. The anchor bolt is embedded in such a way that the head has a protrusion or a recess that engages in the axial direction on the mating surface with the block, and the head engages in the axial direction so that the head can be inserted with a gap. The block includes a block in which a hole having a convex portion or a concave portion is bored, and is hardened by not only adhering the mating surfaces but also injecting an adhesive into the gap between the hole and the head.

[0005]

[Operation] Apply adhesive to the mating surfaces and attach the sliding surface block to the concrete body, and at the same time fill the gap between the hole and the head with adhesive and let it harden.

[0006]

[Example] An example will be described with reference to FIG. An anchor bolt 3 is buried so that its head protrudes from a mating surface B of the concrete body 1 with the sliding surface block 2. As the anchor bolt 3, a commercially available one having a screw 3a carved in the head can be used. At the position corresponding to the anchor bolt of the sliding surface block 2, there is a screw 3 of the anchor bolt head.
A first-stop screw hole 2a is drilled through which the hole 2a can be inserted with a gap, and an adhesive injection hole 2 is connected to the back of the screw hole.
b is drilled from the side.

[0007] To bond the sliding surface block 2 to the concrete body 1, apply adhesive to the mating surface B and stick it together, and fill the gap A between the anchor bolt head and the screw hole of the block 2 with adhesive. , wait for the glue to harden. The adhesive to be filled in gap A will utilize not only the adhesive effect after curing, but also the strength of the adhesive itself, so use one that has greater strength rather than adhesive performance, and
As the adhesive, adhesives having different properties may be used, such as those having good adhesive performance.

[0008] The head of the anchor bolt and the hole through which the head is inserted with a gap are not limited to those with screws, for example, the shafts of grooves, ridges, etc. Of course, any convex portion or concave portion that engages in the direction can be used regardless of the shape.

[0009]

[Effects of the Invention] Since the present invention is constructed as described above, it produces the following effects. In addition to gluing the processed sliding surface block to the concrete body, we also filled the gap between the anchor bolt head, which has a screw or groove, and the hole in the sliding surface block, with sufficient adhesive. It is now possible to ensure the strength and accuracy after installation,
No post-processing is required, and a structure with a short construction period can be obtained at low cost.
