Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a watt-

The present invention relates to an apparatus for connecting a plurality of steel plates.

When concrete construction such as construction, civil engineering, and underground structures is completed, the submerged construction can be carried out following the installation of the line.

As the concrete of the after trowel is dried, voids may be generated at the joint between the line casting part and the after troweling part. A waterproof plate may be used to prevent water leakage generated through the gap at this time.

Since the joint portion between the line-poured portion and the after-tread portion is usually straight, the plate is generally formed in a plate shape extending in one direction.

However, in the case where the joint portions of the sun lay portion and the follower portion are not straight lines, a plurality of the water level plates may be installed crosswise in different directions.

If the processing at the crossing point at this time is insufficient, the leakage phenomenon may not be reliably prevented. Thus, the importance of the members connecting the respective plate members at the intersection points is emerging.

Korean Patent Publication No. 0761567 discloses a structure for connecting two water level plates. However, the structure is intended to connect two steel plates extending in the same direction, and it is difficult to install them at the intersections of the steel plates extending in different directions.

Korean Patent Registration No. 0761567

The present invention is intended to provide an apparatus for connecting a plurality of metal plates.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not intended to limit the invention to the precise forms disclosed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator. Definitions of these terms should be based on the content of this specification.

1 is a cross-sectional view showing a tunnel constructed by the NATM (New Austrian Tunneling Method) method. Fig. 2 is a schematic view showing a structure of the installation of a water resistance plate in the tunnel of Fig. 1;

During the construction of the tunnel by the NATM method, a circular excavation (1) is formed by injecting shotcrete on the wall surface to prevent gradual blasting of the ground and collapse of the rocks. Shotcrete refers to pouring concrete or mortar onto the wall by spraying it with air pressure or the like.

The waterproof sheet 2 is applied to the wall surface of the circular oyster 1 in which the shotcrete is placed, and a cylindrical mold (not shown) can be inserted. The length of the formwork is formed within a few meters in consideration of workability.

Then, concrete is injected and cured in a space between the cylindrical mold and the circular oyster 1, and then the cylindrical mold is separated to form a concrete lining (3). The concrete lining (3) of the next part is continuously laid while repeating this process.

At this time, the waterproof sheet 2 may be used to protect the interior of the tunnel from penetration of groundwater.

The waterproof sheet 2 can be attached in the circumferential direction of the circular oyster 1. [ Since it is difficult to prevent the leakage of water by the waterproof sheet 2 only at the joint portion of each concrete lining 3, the waterproof sheet 2 prevents water leakage at the joint by attaching the waterproof plate 4 as shown in Fig. At this time, the water level plate 4 may be interposed between the concrete lining 3 and the waterproof sheet 2. [

Fig. 3 is a schematic view showing a cross section of the diaphragm 4 installed in the tunnel.

The diaphragm 4 has a plate-like body portion 10 covering a joint portion formed between each concrete lining 3, that is, a lining joint 9, a body portion 10 extending from the body portion 10 toward the concrete lining 3 And may include a protruding central portion 25 and a second anchor portion 30.

The central portion 25 protrudes in the vertical direction of the main body portion 10 having a planar shape and can be disposed in the lining joint 9 in which two lining concrete faces as shown in FIG.

A hollow bulb-shaped hollow portion 24 may be provided in the central portion 25. According to the hollow portion 24, the central portion 25 can be freely deformed in conformity with the shape of the lining joint 9. As a result, the central portion 25 can effectively close the lining joint 9 against leakage.

A plurality of second anchors 30 are provided on the left and right sides of the central portion 25 in a sectional view, and can be coupled to the two lining concrete, respectively. The protrusion 31 may be provided at an end of the second anchor portion 30. [

The protrusion 31 may be a wrinkle formed on the side surface of the second anchor portion 30 or an element protruding laterally from the side surface of the second anchor portion 30. [ According to the projection 31, the coupling force between the second anchor portion 30 and the concrete lining 3 can be increased.

According to the above configuration, even if foreign matter such as rainwater penetrates the circular oyster 1 including the shotcrete and the waterproof sheet 2, the foreign matter can reach the lining joint 9 only if it passes through the path. The path a is a gap between the main body 10 and the concrete lining 3, a gap between the second anchor part 30 and the concrete lining 3 provided in plural, a gap between the center part 25 and the concrete lining 3, It is virtually impossible for foreign matter to penetrate through the path through the gap.

If the support portion 40 for supporting the water expansive index agent 50 is added to the body portion 10, the path expansions will become more complicated by the water expansive index agent 50 that absorbs water and expands.

However, since the length of the water level plate 4 is not infinite, the water level plate 4 can be cut at a specific position of the construction member including the circular oysters and the like. At this time, another water resistance plate may be connected to the water resistance plate. At this time, leakage is likely to occur through a gap between the two water resistance plates (4).

Particularly, when the water resistance plate 4 intersects at the point X as shown in FIG. 2, a problem may occur in the waterproof function. From another point of view, the waterproof function can be greatly damaged if a plurality of waterproof plates are connected at the X-point of the construction member.

Referring to FIG. 2, it can be seen that the diaphragm 4 extending horizontally lies above the diaphragm 4 extending vertically at the intersection X. In this case, there is no problem in the waterproof function of the vertically extending waterproof plate 4, but the waterproof function of the waterproof plate 4 extending in the horizontal direction may be damaged. This is because a part of the second anchor portion 30 may be detached from the concrete lining as the transverse diaphragm rides over the longitudinal diaphragm.

In order to prevent such a phenomenon, the present invention can be used with a plate connecting device.

FIG. 4 is a perspective view showing the apparatus for connecting the apparatus of the present invention, and FIG. 5 is a plan view showing the apparatus for connecting the apparatus of the present invention.

The diaphragm connector 100 shown in the figure may include a body portion 110 and a lid portion 150.

The body portion 110 may be formed in a plate shape whose side faces the end portion of the water resistance plate 4. The body 110 may be in close contact with a construction member, for example, a concrete lining 3, on which the water resistance plate 4 is installed. That is, the body portion 110 may cover the concrete lining 3. [ The body 110 may be disposed at a point where a plurality of the water resistance plates 4 are connected to each other in the lining joint 9. Or the body portion 110 may be disposed at a point where a plurality of lining joints 9 that extend in different directions meet, i.e., at an intersection point X. At this time, the intersection point X may be a point where the plurality of the water level plates 4 intersect.

The body part 110 may be provided with a first anchor part 130 protruding toward the installation member and installed on the installation member. Specifically, the first anchor portion 130 may protrude from the body portion 110 in a direction perpendicular to the plate-like body portion 110.

The first anchor portion 130 may be inserted into the concrete lining 3 in the same manner as the second anchor portion 30 provided in the water level plate 4. [ In addition, the end of the first anchor portion 130 may face the end of the second anchor portion 30. [

A plurality of the water level plates 4 may be connected to the body 110. At this time, the first anchor portion 130 may extend from a specific water level plate to another water level plate.

For example, when the first and second watertight plates provided with the second anchor portion 30 are connected to the body portion 110, the first anchor portion 130 may extend from the first watertight plate toward the second watertight plate . At this time, one end of the first anchor part 130 is in close contact with the second anchor part of the first water level plate, and the other end of the first anchor part 130 is in close contact with the second anchor part of the second water level plate.

According to this, if the first and second watertight plates extend along the same imaginary line, the first anchor portion 130 can be linearly formed on a plane. At least a part of the section between the opposite ends of the first anchor part 130 may be bent if the first and second diaphragms are connected to the body part 110 in different directions. The bending of a part of the first anchor part 130 may be performed such that one end of the first anchor part 130 extends in the same direction as the extending direction of the first end plate 130, As shown in FIG. The second anchor portion 30 provided in each of the water level plates 4 also extends in the same direction as the water level plate 4 so that at least the extending direction of the end portion of the first anchor portion 110 can be the same as that of the water level plate 4. As a result, the end portion of the first anchor portion 130 can be firmly attached to the end portion of the second anchor portion 30. In addition, the above-described path N may be formed continuously on the watertight plate 4 in the watertight connection apparatus.

However, it is not preferable that the curvature of the first anchor part 130 is abrupt according to the molded member.

For example, when the molded member is a concrete lining 3, the concrete lining 3 may include a steel structure such as gravel. At this time, the gravel having a predetermined curvature may be positioned on the bent portion of the first anchor 130. If the curvature of the curb is larger than the curvature of the curb, there may be a gap between the curb and the curb to allow foreign matter to penetrate. To eliminate these gaps, the bend can be curved in a plane.

In other words, the first anchor portion 130 can be bent in a plane with a set curvature. The set curvature at this time may be equal to or less than the curvature of the material constituting the construction member. In other words, the curvature radius R1 of the curved surface may be equal to or larger than the curvature radius of the material constituting the installation member. According to this, the installation member can be surely adhered to the side surface of the first anchor portion 130.

According to the above configuration, a plate-like plate connection apparatus of a type similar to that of the plate 4 can be provided. However, when only the body 110 and the first anchor 130 are formed, a gap is generated again at the joint between the first anchor 130 and the second anchor 30. Therefore, .

In order to prevent this, the cover plate portion 150 may be added to the plate connector of the present invention.

The lid portion 150 may extend from the side surface of the body portion 110 toward the diaphragm 4 so as to cover the diaphragm 4. [

The lid part 150 may be integrally formed with the body part 110 and may have a plate shape having the same thickness as the lid part 150. The lid part 150 may be provided in the same number as the number of the water resistance plates 4 connected to the body part 110.

For example, when four water level plates 4 are connected to the upper, lower, left, and right sides of the body 110 in a plan view, the lid 150 may be provided at four places on the upper, lower, left, and right sides of the body 110. Each lid 150 may extend along the extending direction of each of the water resistance plates 4 connected to the body 110.

Specifically, it is assumed that the body 110 is placed in the xy plane in an xyz three-dimensional space having x-axis, y-axis, and z-axis orthogonal to each other. When the diaphragm 4 connected to the body 110 extends in the x-axis direction or the y-axis direction, the lid 150 is moved from the body 110 in the positive x-axis direction, the negative x- The positive y-axis direction, and the negative y-axis direction.

The four water level plates 4 may be connected to the body 110 corresponding to the number of the lid units 150. For example, the four diaphragms 4 may be similar to the diaphragm 4 intersecting each other in Fig. 2 with the intersection point X removed.

Fig. 6 is a plan view showing a state in which the diaphragm 4 is installed on the diaphragm connecting device of the present invention.

The body portion 110 is disposed at the intersection point X and each lid portion 150 extending from the body portion 110 can be superimposed on each of the water level plates 4. In FIG. 6, two lids 150 are provided in the x-axis direction and two in the y-axis direction with the body 110 as the center.

According to the lid unit 150 described above, it is possible to restrict the inflow of foreign matter penetrating along the positive direction of the z-axis in the gap between the main body 110 and the diaphragm 4, which face each other.

The first anchors 130 may be formed in a variety of ways corresponding to the second anchors 30 provided on the respective watertight plates 4 connected in a plurality of directions.

For example, two of the plurality of adjacent water surface plates 4 are assumed to be the first water surface plate 1 and the second water surface plate 2. At this time, the lid 150 may include a first lid part a over which the first lid plate 1 overlaps and a second lid part b over which the second lid 2 overlaps.

In order to maximize the waterproof effect, the body portion 110 may be provided with a mounting portion 170 extending from one side facing the first side plate to the other side facing the second side plate. The mounting portion 170 may extend in the same direction as the first anchor portion 130 in a plan view. At this time, the mounting portion 170 may be provided for installing the rod-shaped water expansile index agent 50.

For example, the water expansive index agent 50 may be inserted or bonded to the mounting portion 170.

7 is a schematic view showing the mounting portion 170. Fig. Fig. 7 is a cross-sectional view taken along the line A-A 'in Fig.

The mounting portion 170 may protrude in the vertical direction from the body portion 110 similarly to the first anchor portion 130. The mounting portion 170 may be provided with an insertion space 171 into which the water expansive index agent 50 can be inserted and a locking protrusion 173 from the water expansition index agent 50 from being released. According to this structure, the water expansive index agent 50 can be inserted into the mounting portion 170 in such a manner as to be fitted from the end portion of the mounting portion 170. An adhesive may be applied between the mounting portion 170 and the water expansition index agent 50. According to the adhesive, the water expansition index agent 50 is bonded to the mounting portion 170, so that the water expansition index agent 50 and the mounting portion 170 can be fastened more reliably.

When a plurality of the water level plates 4 extending in different directions are connected to the body 110, the mounting part 170 can be curved in a curved shape like the first anchor part 130 in plan view.

8 is a schematic view showing a state in which the water expansition index agent 50 is inserted into the installation part 170. Fig. 8 shows a mounting portion 170 having one end extending in the y-axis direction and the other end extending in the x-axis direction.

The mounting portion 170 can be bent in a curved shape so that both ends extend along different directions.

At this time, the curved shape may be for advancing the end of the water expansile index agent 50 fitted to one side of the installation part 170 to the other side of the installation part 170. Therefore, the radius of curvature R2 of the curved portion of the curved portion of the mounting portion 170 can be determined to a degree that the water expansion index can be advanced while being bent by a force applied in a specific direction. R2 can be obtained through repeated experiments. 8, a state in which the water expending exponent 50 entering the mounting portion 170 in the positive direction of the y-axis is bent along the mounting portion and is advanced in the negative direction of the x-axis is started.

On the other hand, the end of the second anchor portion 30 is installed in a state of being aligned with the end portion of the first anchor portion 130 in order to allow the path (s) good.

However, the lid 150 or the body 110 may not be provided with a separate means for aligning the lid 4, except for the lid 150. In this case, when the diaphragm 4 is disposed on the lid 150, it may be difficult for the first anchor portion 130 and the second anchor portion 30 to be aligned on exactly the same imaginary line L1. Accordingly, the first anchor portion 130 and the second anchor portion 30 may be disposed in a staggered state. The end face of the second anchor portion 30 facing the first anchor portion 130 may be formed of a material having a high elastic modulus as long as the second anchor portion 30 has a flexible property It is easy to bend in various forms. At this time, the first anchor 130 and the second anchor 30 may be difficult to come into contact with each other due to the warping.

The first anchor portion 130 of the present invention may have a special structure for reliably bringing the first anchor portion 130 and the second anchor portion 30 into close contact with each other.

9 is a perspective view showing the first anchor 130 of the present invention.

For example, the width W0 of the end portion of the first anchor portion 130 facing the second anchor portion 30 may be greater than the width of the end portion of the second anchor portion 30. [ The end of the second anchor portion 30 can be accurately brought into contact with the end portion of the first anchor portion 130 even if the second anchor portion 30 is partially displaced or bent from the first anchor portion 130 have.

On the other hand, the body 110 may be made of a flexible material like the water resistance plate 4. For example, the body 110, the first anchor 130, and the lid 150 may include polyvinyl chloride (PVC).

Flexible steel plate connection devices may be flammable, which can cause difficulties in handling during storage, transportation and installation. In order to solve this problem, it is recommended that measures be taken to eliminate some of the flicker.

For example, when the body portion 110 is disposed in the xy plane, the body portion 110 is prone to flaring along the z-axis. However, the fussing of the body portion by the first anchor portion 130 or the like protruding in the z-axis direction can be limited to a level at which there is no problem in handling.

However, since the lid part 150 extending from the body part 110 does not have an element protruding in the vertical direction from the lid part 150, the lid 150 may be severely curled. The lid 150 may be provided with a first guide 111 to restrict the loudness of the lid 150.

4 and 5, the first guide part 111 may protrude from the lid part 150 in the vertical direction. If the first guide part 111 is formed only on the lid part 150, the lapping of the lid part 150 itself may be restricted. However, if the first guide part 111 is formed only on the lid part 150, Fuzziness is difficult to limit.

The first guide portion 111 may be formed to extend from a specific lid portion to another lid portion or may be formed over a specific lid portion and a body portion in order to reduce the flickering of the lid portion 150 with respect to the body portion 110 . For example, in FIG. 4, a first guide portion 111 formed over two adjacent lid portions 150 is disclosed. If one first guide portion 111 is formed over a plurality of lid portions, flickering may occur only when the plurality of lid portions 150 are moved together. However, the movement of the plurality of lid parts 150 together is not easy compared with that of the one lid part 150, so that the lapping of the lid part 150 with respect to the body part 110 can be reduced.

One end of the first guide part 111 extends along the extending direction of the specific lid part 150 and the other end of the first guide part 111 extends along the extension direction of the specific lid part 150. When the first guide part 111 is formed over the lid part 150 extending in different directions, The other end of the one guide part 111 may extend along the extending direction of the other lid part 150. According to this, the lapping of each lid portion can be minimized.

The first guide part 111 can be used for aligning the water proof plate 4 and the body part 111 by using the characteristic protruding from the lid part 150.

For example, when the diaphragm 4 is connected to the body 110 in the first direction, the lid 110 is provided with two first guide portions 111 at different positions in a second direction perpendicular to the first direction, May be provided. The distance between the first guide portions 111 may be the same as the width of the water guide plate 4 so that the water guide plate 4 is aligned with the body portion 110.

Specifically, the lid b in Fig. 4 will be described.

The lid part (b) may extend in the x-axis direction from the body part (110). The lid part (b) may be provided with a water resistance plate (4) extending along the x-axis corresponding to the first direction in the x-axis direction. At this time, two first guide portions 111 may be used as a means for regulating both end portions in the width direction (y-axis direction) of the water guide plate 4. [

Two first guide portions 111 may be formed at y1 and y2, respectively, in the width direction of the diaphragm 4 corresponding to the second direction. At this time, if the distance between y1 and y2 is equal to the width of the diaphragm 4, that is, between the diaphragm 4 and the diaphragm 4, the diaphragm 4 can be sandwiched between the two first guide portions 111. [

Thus, the diaphragm 4 fitted to the first guide portion 111 is restricted in the movement in the second direction and can be aligned with the body portion 110 at least in the second direction.

In this state, when the alignment of the diaphragm 4 and the body 110 is completed in the first direction, alignment between the diaphragm 4 and the body 110 can be completed.

In order to guide the position of alignment of the diaphragm in the first direction, the second guide part 112 may be provided on the plate connector of the present invention.

The second guide portion 112 may be formed on the side surface of the body portion 110 facing the diaphragm 4. The second guide part 112 may protrude from the body part 110 in the vertical direction.

The cover 150 may extend from the side of the body 110 as previously described. Therefore, the end of the diaphragm 4 approaching the body 110 along the first direction on the lid 150 can be caught by the second guide 112. If the first direction is the x-axis and the first guide part 112 is formed at the x1 position, the end of the diaphragm 4 can be aligned to x1.

Fig. 10 is a cross-sectional view showing a plate connector of the present invention. Fig. Fig. 10 is a cross-sectional view of a part of the lid b in Fig.

When the side surface of the body portion 110 is provided at the x1 position in the first direction, the second guide portion 112 may protrude from the x1 along the z-axis direction. The second guide portion 112 protruding in the z-axis direction can function as a latching jaw that prevents the movement of the diaphragm 4 entering the lid 150 in the x-axis direction.

and the end of the first anchor part 130 may be positioned at the x1 position. Since the first anchor portion 130 is a line contact element to the second anchor portion 30 formed on the water level plate 4, the movement of the water level plate 4 may be blocked by the anchor portions 130 and 30. However, due to the flexible nature, each of the anchor portions that are line-contacted is prone to collapse, and the end portion of the diaphragm 4 may not be accurately aligned to x1 due to the collapse at this time. This phenomenon may be more prominent if each anchor portion is not in line contact due to bending of each anchor portion due to its flexible property, and is in point contact.

The second guide portion 112 is provided for accurately aligning the diaphragm 4 in the first direction at the set position x1 and can be opposed to the main body portion 10 of the diaphragm 4 instead of the second anchor portion 30. [ have.

The protrusion height W1 of the second guide portion 112 may be equal to the thickness of the diaphragm 4 with respect to the lid portion 150 in order to abut the end portion of the main body portion 10. [ The body portion 10 in the water level plate 4 may be less prone to collapse due to collision with the waterproof plate connecting device as compared with the second anchor portion 30. [ Therefore, according to the second guide portion 112 for blocking the main body 10, the diaphragm 4 can be accurately aligned with x1.

However, if the second guide portion 112 is collapsed along the first direction due to the collision with the water level plate 4, the alignment effect of the water level plate 4 can be attenuated. In order to prevent the second guide part 112 from being distorted in the first direction, the second guide part 112 may extend along the first direction. In order to reduce the material required for forming the extended second guide part 112, the protrusion height of the second guide part may be increased from the specific position x0 of the body part 110 to the edge x1 of the body part 110. [ In other words, the second guide portion 112 may be formed to be inclined in the first direction.

10, the height of the second anchor portion 30 may be the same as the height of the first anchor portion 130 in a state where the diaphragm 4 is superimposed on the cover portion 150. [ The protrusion height W4 of the first anchor part 130 and the protrusion height W3 of the second anchor part may be different from each other.

For example, the protrusion height W4 of the first anchor portion 130 protruding from the body portion 110 is equal to the sum of the thickness W1 of the body portion 10 constituting the diaphragm 4 and the protrusion height W3 of the second anchor portion Can be the same.

When the plurality of water resistance plates 4 are connected to the flexible body portion 110, the body portion 110 can be twisted by the force applied from each of the water level plates 4 irrespective of the first anchor portion 130 have. The body 110 may also perform a waterproof function at the intersection X by the first anchor 130. [ However, if the body part 110 is twisted, the waterproof function may be damaged.

Therefore, regardless of the force provided from each of the water level plates 4 and the force to twist the body portion 110, the body portion 110 may be in close contact with the intersection point X or the like. To this end, an element may be provided for receiving an external force applied from the water level plate 4 or the like and biting the body part 110 in place of the body part 110. [

11 is a perspective view showing a rear surface of a waterproof plate connecting apparatus according to the present invention.

For example, the body portion 110 may be provided with a groove-shaped rib 190. At this time, the ribs 190 may extend in the direction from the center O of the body portion 110 to the respective diaphragms 4. The rib 190 formed at the center O of the body 110 may be deformed earlier than the body 110 when an external force for deforming the body 110 is applied. According to the ribs 190, the body 110 can be prevented from being deformed. The rib 190 is an element on the extension of the central portion 25 of the diaphragm 4 and can also serve to close the lining joint 9 located at the crossing point X or the like.

According to the present invention, it is possible to increase the installation convenience of the water level plate 4 by using the lid 150 functioning as a guide, and to prevent leakage of water between the water level connection with the water level plate 4 . In addition, the first anchors 130 connected to the plurality of the water level plates 4 and bent to form a pathway in which foreign matter hardly passes can be provided. Further, the width of the end portion of the first anchor portion 130 is enlarged to easily connect the diaphragm 4. A rib 190 may be provided to prevent the body 110 from being warped.

The second guide portion 112 can align the position of the diaphragm 4 and the diaphragm connecting member 100 in the first direction.

As described above, the end portion of the first anchor portion 130 provided on the diaphragm connecting member 100 is formed to be thicker than the end portion of the second anchor portion 30. For this, the width of the end portion in the first groove portion 213 may be larger than the width of the specific section between the both ends.

The plate portion 211 and the plate portion 221 may be provided with a second groove portion 217 in order to form the mounting portion 170 in which the water expansive index agent 50 is installed.

However, as described above, the mounting portion 170 may be provided with a latching protrusion 173 for preventing the water expansive index agent 50 from coming off. It is possible to prevent the diaphragm connecting member 100 from being detached from the mold 200 by the engaging jaw 173 at this time. The insert core 290 may be inserted into the second groove 217 to prevent the diaphragm connecting member 100 from being caught in the second groove 217. [

14 is a perspective view showing an insert core 290 installed in the connecting member manufacturing apparatus of the present invention.

The insert core 290 includes a space forming portion 291 for forming an insertion space 171 into which the water expansive index agent 50 is inserted in the mounting portion 170, And an extension portion 293 extending in the vertical direction of the protrusion 293. The width of the extending portion 293 may be smaller than the width of the space forming portion 291 in order to form the latching step 173 of the mounting portion 170. [ A barrier 295 may be formed between the space forming portion 291 and the extending portion 293 to form the engaging protrusion 173 of the diaphragm connecting member 100.

The second groove portion 217 and the insert core 290 prevent the insertion space 171 into which the water expansive index agent 50 is inserted and the water expansive index agent 50 from being separated from each other A mounting portion 170 having a locking protrusion 173 may be formed.

15 is a schematic view showing a cross section of the second groove 217 and the insert core 290. Fig.

The mounting portion 170 provided in the die plate connecting member 100 may be formed by the space between the insert core 290 inserted into the second groove 217 and the second groove 217. [ The width of the second groove 217 may be larger than the width of the space forming portion 291 of the insert core 290 and the width of the extending portion 293 so as to form a space.

An insertion groove 218 for inserting an extension portion 293 of the insert core 290 is formed on the bottom surface of the second groove portion 217 so as to fit the insert core 290 .

Fig. 15 (b) shows a state of the insert core 290 provided in the second groove portion 217 through the insertion groove 218. Fig. 15 (b), it is understood that the shape is the same as the cross-sectional shape of the mounting portion 170 shown in FIG.

Meanwhile, the insertion groove 218 may be provided with a spin pin hole 280 into which the spin pin 60 is inserted. The microneedle 60 may be a mechanism for pushing the diaphragm connecting member 100 from the mold 200 after molding is completed. The microneedle 60 may move through the microneedle hole 280 provided in the mold 200. The microneedle 280 may be disposed at various places other than the insertion groove 218. [ However, there is an advantage that no mark is left on the diaphragm connecting member 100 even after the diaphragm connecting member 100 is formed in the insertion groove 218.

In the above configuration, the insert core 290 may remain in the die plate connecting member 100 separated from the mold 200 by the microneedle 60. At this time, the insert core 290 may be released in the lateral direction of the mounting portion 170. If the mounting portion 170 has a curved shape at a specific point, the insert core 290 may be divided into a plurality of members. The water expansion index agent 50 may be inserted into the mounting portion 170 where the insert core 290 is removed.

According to one embodiment of the present invention, the insert core 290 may be a water expansive index agent 50 inserted into the mounting portion 170 in the diaphragm connecting member 100. The insert core 290 and the mold 200 can be contacted with the molding material of the diaphragm connecting member 100 having the molten state. Therefore, the water expansion index agent 50 used for the insert core 290 needs to be insoluble at the temperature of the molding material. That is, it is preferable that the melting point of the water expansion index agent (50) has a melting point higher than that of the water resistance member (100).

According to this, the step of removing the insert core 290 from the die 200 and removing the diaphragm connecting member 100 and providing the water expansive index agent 50 in place can be omitted. This is because the water expansile index agent 50 is provided on the mounting portion 170 only by removing the diaphragm connecting member 100 from the mold 200.

In addition, according to this, it is possible to easily form the mounting portion 170 and the water expansive index agent 50 having various sectional shapes.

16 is a cross-sectional view showing a water expansion index agent 50 used as an insert core 290. Fig.

The cross-sectional shape of the water expansition index agent 50 shown in Fig. 16 has a complicated shape compared to the water expansition index agent 50 of Fig. Even if a wrinkle extending in the radial direction from the center of the water expansition index agent 50 is provided in the cross section, the water expansition index agent 50 in a state of being installed on the mounting portion 170 can be obtained without any difficulty.

In addition, since the molten molding material is naturally adhered to the water expansive index agent 50, a separate adhesive for the two adhesives may not be required.

Referring back to FIG. 12, the mold 200 may include a first mold 210 and a second mold 220 facing each other.

The first mold 210 may have plate portions 211 and 221, a first groove portion 213, a second groove portion 217, a third groove portion 219, and the like.

For reference, the plate portions 211 and 221 may be formed separately from the first and second molds 210 and 220.

For example, when the thickness of the plates 211 and 221 is a, the first plate 210 may be provided with a first plate 211 having a thickness b smaller than a (intaglio height). The second mold 220 may be provided with a second plate 221 having a thickness c obtained by subtracting b from a.

The first mold 210 may be formed with a spin pin hole 280. As described above, the shaft pin 60 for detaching the diaphragm connecting member 100 from the first mold 210 may be inserted into the shaft hole 280 (see FIG. 15). The first mold 210 is provided with a first groove 213 in which the formed index plate connecting member 100 is tightly tightened. Therefore, it is preferable that a pin hole 280 for applying an external force is provided. The second mold 220 may be provided with a miliphin hole 280 according to the user's selection.

In order to prevent damage to the first anchor 130 protruding in the vertical direction from the body 110 in the diaphragm connecting member 100, the dipper hole 280 is formed at a position where the first anchor 130, . For example, the pin hole 280 may be provided at a position facing the body 110 of the diaphragm connecting member 100 in a plane or at a position where the insert core 290 is inserted.

Meanwhile, the second mold 220 may be provided with an injection port 260 through which the molding material of the diaphragm connecting member 100 is injected.

17 is a schematic view showing an injection port 260 provided in the second mold 220. FIG.

Only one injection port 260 may be disposed in the second mold 220. The injection port 260 may be formed to face the center of the plate portions 211 and 221 so as to uniformly propagate the molding material injected from the injection port 260 to the entire plate portions 211 and 221, have.

Meanwhile, the first mold 210 may be provided with a third trench 219. The third trench 219 may extend vertically and laterally from the center of the plate portions 211 and 221 on a plane.

The second mold 220 may be provided with a cross-shaped insertion portion 223 inserted into the third groove 219 corresponding to the third groove 219. At this time, the formation position of the insertion portion 223 may overlap the formation position of the injection port 260.

The insertion portion 223 may be an element protruding from the second plate portion 221 in the position of the second mold 220. Therefore, when the injection port 260 is provided in the insertion portion 223, propagation of the molding material by the insertion portion 223 can be restricted.

A communication groove 261 extending in the radial direction from the injection port 260 may be formed on the inserting portion 223 in a planar manner so that the molding material is effectively propagated.

For example, referring to FIG. 17, the insertion portion 223 extends from the injection port 260 in four directions orthogonal to each other, that is, in a cross shape. At this time, the communication groove 261 may extend in a diagonal direction, that is, a shape in which the upper cruciform shape is rotated by 90 degrees.

According to this, the molding material can easily spread into the plate portions 211, 221 or the first groove portion 213 through the communication groove 261.
