When described with reference to the above-mentioned drawings, in the method of manufacturing a seismic coupler manufacturing unit for a computational bolt for fixing a structure according to an embodiment of the present invention and a manufacturing method of a seismic coupler for a computational bolt for fixing a structure using the same, first, the structure is fixed It will be described with respect to the seismic coupler manufacturing unit for computational bolts for.

Prior to the detailed description, the seismic coupler in the present invention, as described above, in order to maintain and fix the structure spaced apart from the ceiling, the anchor bolts fixed to the ceiling and the computerized bolts installed on the pedestal on the side of the structure or the structure itself As a configuration interposed between the body 100 as a buffer member, the first binding sphere 200 of the anchor bolt side, and the second binding sphere 300 of the computerized bolt side are coupled.

Seismic coupler is preferably a first binding sphere 200 is bolted to the anchor bolt 2 as shown in FIG. 5 , and the second binding sphere 300 is bolted to the computerized bolt 3 . At this time, upon completion of manufacture, both end sides of the body 100 are deformed to narrow while forming a curved surface toward the narrowest portion 211 while surrounding the spherical portion 211 of the first binding sphere 200 and , while enclosing the spherical part 311 of the second binding sphere 300 and forming a curved surface toward the narrowest part 311, the width is narrowed, respectively, as a result, the body 100, the first binding As the sphere 200 and the second binding sphere 300 are connected as shown in FIG. 5 , when vibration is applied, the body 100 , the first binding sphere 200 and the second binding sphere 300 are 3 It absorbs vibration while moving in the axial direction, and when the vibration is removed, it functions as an earthquake-resistant coupler in a way that it returns to its original state in a straight line. That is, in the height direction, each width is limited to the narrowest portions 212 and 312 so that vibration is absorbed while both ends of the body 100 are moved, and in other directions, both ends and a spherical shape of the body 100 are defined in all directions. Vibration is absorbed by the free hinge movement due to engagement with the portions 211 and 311 and the narrowest portions 212 and 312 .

At this time, in the present invention, the body 100 does not have any strength weakening elements such as any slits, and at the same time, the spherical parts 211 and 311 are forcedly inserted in a state where both ends are narrowed in width. The first binding sphere 200 or the second binding sphere 300 and the body 100 do not completely return to the narrowed state from the widened state due to the forced fitting of both end sides to maintain this narrowed state. ) to completely prevent the separation phenomenon, a manufacturing unit and a manufacturing method using the same are applied to be described later.

In the present invention, the same description and technical features will be applied to the binding spheres 200 and 300 without distinction unless there is a characteristic description for each of the binding spheres 200 and 300 in the present invention, and the body 100 is As shown in FIG. 3, the shape before manufacturing the earthquake-resistant coupler and the width of both ends are narrowed as shown in FIG. It should be understood as a concept that includes all the shapes of the manufactured state so that movement in all directions is possible at the same time while preventing separation by jamming with each other according to each manufacturing process.

When described based on the above concept, the manufacturing unit specifically includes the first mold 10 as shown in (a), (b), (c), (d) of FIG. 1 . The first mold 10 includes a pair of semi-cylindrical first sub molds 11 and 12 equally divided in the radial direction to form a cylinder when in contact with each other. A first area 112 with an open short side is formed on the short side to accommodate the narrowest part of the first binding sphere 200 fastened to the anchor bolt or the second binding sphere 300 fastened to the computerized bolt, and the other The short side accommodates the spherical parts 211 and 311 of the first binding sphere 200 or the second binding sphere 300, and at the same time, a second region 111 with an open short side so that the cylindrical body 100 can be inserted. ) is formed, and the second region 111 is formed to have a narrow width while forming the curved surface 113 in the direction toward the first region 112 .

As a specific example, as shown in the drawings, the second region 111 accommodates the spherical parts 211 and 311 and at the same time allows the body 100 to be fitted into the spherical parts 211 and 311. , the maximum width d3 of the second region 111 is greater than the width of the body 100, preferably the maximum width d4 of the spherical parts 211 and 311 as shown in the drawings and the body 100 In relation to the outer thickness d6 of , at least d3 may be set to be d4+2xd6.

On the other hand, the width of the region closest to the first region among the regions in which the curved surface 113 is formed is the width d5 of the narrowest portions 212 and 312 of the binding spheres 200 and 300 and the outer shape of the body. The thickness d6 may be formed to be a value obtained by adding the values of both sides. Through this, when the seismic coupler is manufactured, when a strong press is applied in a state in which each binding hole 200 and 300 is inserted to accommodate the body 100, the body 100 receives pressure along the curved surface 130 and the The width of both ends is deformed to be narrow, and finally the narrowest part of the short side is in contact with the narrowest parts 212 and 312 of each binding sphere 200, 300, so that the earthquake resistance as shown in FIG. The coupler can be completed.

On the other hand, the first mold 10 forms a cylindrical shape while a pair of first sub molds 11 and 12 are in contact, which is a case in which the first sub molds 11 and 12 are not separated during manufacture. , 300) and the body 100 cannot be arranged. For this reason, when each of the first sub molds 11 and 12 having a semi-cylindrical shape are brought into contact with each other to complete the shape of the first mold 10, and then press in the direction toward the body 100, the The first sub molds 11 and 12 are separated. In order to prevent this phenomenon, the second mold 20 is applied to strongly maintain the shape of the first mold 10 .

Referring to (a) and (b) of Figure 2, the second mold 20 has a non-separated cylindrical structure, and one end in the height direction is coupled to the anchor bolt or the computerized bolt of the first binding tool 200 in the height direction. A third region 22 into which the region can be inserted is formed, and on the other end side, a fourth region (no identification number, shown in FIG. 2 ) with an open end so that the first mold 10 can be inserted and fixed 1 is a configuration in which a dotted line region corresponding to the mold 10) is formed.

In the above-described example, since the body 100 has to be coupled with the two binding spheres 200 and 300 , the first mold 10 and the second mold 20 described above are also one each on the side of the anchor bolt and the computerized bolt. By disposing the two binding spheres 200 and 300 with the body at the same time during manufacturing, both end sides of the body 100 can be simultaneously deformed into a shape corresponding to the curved surface 130 .

A specific process for manufacturing the earthquake-resistant coupler using the first mold 10 and the second mold 20 is as follows.

First, as shown in Fig. 4 (a), the first pair of sub-molds 11 and 12 in a state where the inner open area of the body 100 in the form of Fig. 3 is arranged to accommodate the first binding sphere 200 . ) wrapped around the first binding sphere 200 and brought into contact with each other to form a cylindrical first mold 10 , and the inner open area of the body 100 is arranged to accommodate the second binding sphere 300 . The pair of first sub-molds 11 and 12 are placed in contact with each other while wrapping the second binding sphere 300 to form another first mold 10-1 having a cylindrical shape.

Thereafter, as shown in (b) of FIG. 4, the pair of first molds 10 are inserted and fixed to the pair of second molds 20 and 20-1 through the fourth region. By arranging the second mold (20. 20-1), and applying a press (P) in the longitudinal direction, specifically, in the direction toward the body 100, between the second molds (20. 20-1), the first As the body 100 is in contact with the curved surface 130 of the molds 10 and 10-1 according to the press, the short side 101 of the body is deformed to a curved surface along the curved surface 103, both end sides of the body 100 The curved surface of 101 prevents the first binding sphere 200 and the second binding sphere 300 from being separated from the body, and is manufactured to maintain fluidity in the vertical and circumferential directions with respect to the body 100 .

If this is described as each process step, the first pair of sub molds 11 and 12 are first bound in a state where the inner open area of the body 100 in the form of FIG. 3 is arranged to accommodate the first binding tool 200 . The first step of arranging the sphere 200 to be in contact with each other while enclosing the sphere 200 to form a cylindrical first mold 10, the second binding sphere 300 in a state where the inner open area of the body 100 is arranged to accommodate the second binding sphere 300 The second step of arranging a pair of sub-molds 11 and 12 to form another cylindrical first mold 10-1 by contacting the pair of sub-molds 11 and 12 while enclosing the second binding sphere 300 is described as (a) of FIG. 4 . can be

Then, a pair of second molds 20. 20-1 are arranged so that each of the pair of first molds 10 is inserted and fixed to the pair of second molds 20 and 20-1 through the fourth region. In the third step, by applying the press P in the longitudinal direction, specifically, in the direction toward the body 100, between the second molds 20. 20-1, the curved surfaces of the first molds 10 and 10-1 A fourth step in which the body 100 is brought into contact with the press with respect to 130 and the end side 101 of the body is deformed to a curved surface along the curved surface 103 may be described as (b) of FIG. 4 .

Thereafter, as the second molds 20 and 20-1 and the first molds 10 and 10-1 are separated in this order, the end side 101 of the body is deformed to a curved surface along the curved surface 103, and the body 100 ), the first binding sphere 200 and the second binding sphere 300 are not separated from the body by the curved surfaces of both end sides 101, and at the same time, maintain fluidity in the vertical and circumferential directions with respect to the body 100 The manufacturing process is complete.

According to the present invention, according to such a manufacturing unit and manufacturing method, it is possible to completely avoid a state in which the strength is weakened by forming a slit in the body 100, and the spherical protrusion parts 211 and 311 are suppressed after the slit is formed.
