Description

{DRY PREFABRICATED VIBRATION ISOLATION TABLE AND ITS MANUFACTURING METHOD}

The present invention relates to a vibration damping device for reducing vibration, and more specifically, to a dry-assembled assembly-type vibration damping device capable of easily installing an externally manufactured vibration damping plate in a dry manner on site and securing performance equivalent to that of a conventional integral vibration damping device, and a method for manufacturing the same.

Precision equipment such as semiconductors and displays are very vulnerable to external vibrations during their manufacturing process, so vibration isolation tables are used to secure high quality and yield by creating a vibration-free environment.

These dampers are typically located between the floor and the precision manufacturing equipment to absorb and damp external vibrations, preventing the precision manufacturing equipment from making contact with the ground and transmitting vibrations directly through the floor.

To this end, a vibration isolation platform is manufactured outside the clean room to match the size of the target manufacturing equipment, and then transported to the site through a lifting process to be installed.

However, when a vibration isolation stand manufactured as a single body is brought into the site according to the size of the target manufacturing equipment, a large space is required for the route, and there are many cases where there are restrictions on lifting work depending on the installation environment. In particular, not only the process of securing the route, but also the process of installing the vibration isolation stand requires a lot of manpower and various costs, and various safety issues also arise due to the dust generated during the installation process, which causes the protection of the manufacturing equipment.

For this reason, some people manufacture the vibration dampers in a split form, bring them to the site, and then install them by welding or wet pouring the joints.

This is because the space required for installation is relatively small, but since the process of connecting the joints on site involves wet methods such as welding and concrete pouring, problems such as fire or dust, which can be fatal to the clean room where precision equipment is installed, can occur.

In particular, there are still issues to be resolved, such as the need to secure a separate curing period to achieve the desired strength during wet pouring of concrete at the joint and concerns about reduced bonding strength at the joint.

Meanwhile, a vibration isolation board can be manufactured in a segmented form and assembled by connecting them in the space provided. In the case of such an assembled vibration isolation board, if a large concentrated load is applied between each segmented vibration isolation board (e.g., vibration isolation plates), the joints connecting each vibration isolation board may be damaged and separated, which may cause stability problems. Therefore, the method of joining the connection parts of each vibration isolation board and the method of connecting each vibration isolation board to the connection part are very important.

Therefore, the definition should be made based on the contents throughout this specification.

The manufacturing process of precision equipment such as semiconductors and displays is a very precise process, so it is very vulnerable to vibrations transmitted from the outside. For example, in the case of photolithography equipment that performs a photo process, since it performs a very precise process of transferring a semiconductor circuit pattern drawn on a photomask substrate onto a wafer, if vibrations occur from the outside, problems in the process may occur. In other words, it is important to absorb and alleviate external vibrations during the manufacturing process of precision equipment.

Accordingly, a vibration damping table is utilized in the manufacturing process of precision equipment. A vibration damping table may refer to a device that is provided to prevent vibration from being transmitted through a medium. Such a vibration damping table is generally located between the floor surface and the precision manufacturing equipment to absorb and alleviate external vibrations so that the precision manufacturing equipment does not come into contact with the ground and vibration is not directly transmitted through the floor surface.

For example, when semiconductor equipment is installed in a semiconductor manufacturing line, it is not installed directly on the floor of the semiconductor manufacturing line, but is installed on a vibration isolation table that absorbs and alleviates external vibration to a certain extent. In other words, a vibration isolation table is prepared in advance in the location where precision equipment vulnerable to vibration, etc. is to be installed, and the precision equipment is installed on the vibration isolation table that is prepared in advance.

Meanwhile, a vibration isolation table installed in a general semiconductor manufacturing line is configured through a single body and can be equipped to support a single semiconductor device. In other words, this vibration isolation table is configured in a structure that cannot be disassembled. In this case, when the semiconductor device is relocated, the existing vibration isolation table cannot be relocated due to its size and body structure. Accordingly, when the semiconductor device is relocated, the existing vibration isolation table cannot be relocated together with the semiconductor device and is dismantled, and a new vibration isolation table is installed again in the new location where the semiconductor device is to be relocated. In this case, not only does the removal of the vibration isolation table generate dust or vibration inside the semiconductor manufacturing line, which has a negative impact on the semiconductor manufacturing environment, but there is also the disadvantage of requiring a lot of manpower, cost, and time to install a new vibration isolation table.

In accordance with these circumstances, some are using prefabricated vibration isolation platforms. In the case of prefabricated vibration isolation platforms, multiple vibration isolation panels are manufactured separately, brought to the site, and then the vibration isolation platform is installed by welding and joining the joints. This has the advantages of requiring relatively little space for installation, being highly convenient to construct, and being advantageous in terms of dust generation and environmental safety.

To explain in more detail, a conventional assembly-type vibration damping device (1000a) can be installed by manufacturing a plurality of vibration damping plates (100a) as shown in Fig. 1 and connecting each manufactured vibration damping plate (100a) on site.

In the case of a conventional seismic plate (100a), as shown in Fig. 1, reinforcing bars (20a) can be formed by stacking them on the inside of a square frame (10a) having a certain height and a square shape. The reinforcing bars (20a) can be arranged in a grid shape in the horizontal and vertical directions as well as the up-down direction inside the square frame (10a), and reinforced concrete is formed as concrete is poured on the upper and lower sides of the arranged reinforcing bars.

As shown in Fig. 2, an assembly member may be formed on one side of each of the damping plates (100a) produced through this process. An assembly member may be welded to an outer side of a square frame, and connection or combination with another damping plate is possible through the assembly member. The assembly member may be configured in various forms. For example, the assembly member may be provided in the form of a metal plate, as shown in Fig. 2, and one end may be welded to one side of the square frame, while the other end may protrude vertically along the side where assembly is performed.

Specifically, a first assembly member (200a-1) may be formed on an outer surface of a first damping plate (100a-1), and a second assembly member (200a-2) may be formed on an outer surface of a second damping plate (100a-2). That is, each assembly member may be welded so as to protrude from one surface of each damping plate. In this case, each of the first assembly member (200a-1) and the second assembly member (200a-2) includes a joining hole, and when the bolting portion (300a) is fastened while each joining hole is aligned, the first damping plate (100a-1) and the second damping plate (100a-2) are connected.

That is, as illustrated in Fig. 3, each of the first damping plate (100a-1) and the second damping plate (100a-2) is formed by pouring concrete while reinforcing bars (20a) are arranged in a grid shape inside each square frame, and a plurality of assembly members are formed on one side corresponding to the side wall. In addition, the first damping plate (100a-1) and the second damping plate (100a-2) can be connected through fastening between the respective assembly members.

In the case of such conventional vibration damping plates (1000a), the development and use are mainly focused on increasing the joint strength between assembly members so that a vibration damping table in which multiple vibration damping plates are assembled in an assembly manner can have a rigidity similar to that of a single integral vibration damping table.

Meanwhile, in order to implement high rigidity of the vibration damping plate, the method of joining between the assembly members of each vibration damping plate (i.e., the method of joining between the first assembly member and the second assembly member) is very important, but the integration between each vibration damping plate and the assembly member can also be a very important consideration.

For example, in the case of a conventional assembly-type vibration isolation stand (1000a), as described above, since the vibration isolation plate and the assembly member are provided with different structures and joined by welding or other methods, a fatal problem may occur in that they may be damaged or separated if a large concentrated load is applied between them.

That is, in order to secure the rigidity and stability of the vibration isolation board implemented through assembly, it is important to improve durability by securing improved connectivity between each vibration isolation board and assembly members.

In addition, in the case of a conventional damping plate (100a) in which reinforcing bars (20a) are arranged in a grid shape on the inside, the durability and quality of the damping plate (100a) body may vary depending on the reinforcement arrangement specifications. Accordingly, in order to improve the durability and quality of the damping plate (100a) itself, it is necessary to increase the amount of reinforcing bars (20a) arranged on the inside, or to design reinforcement arrangement for a solid arrangement. However, if the amount of reinforcing bars (20a) arranged on the inside is increased, the reinforcing bars (20a) must be laminated in a grid shape, which may increase the manufacturing process time.

In summary, in the case of the conventional assembly-type vibration isolation stand (1000a), there is a disadvantage in that the bonding strength between the vibration isolation plate and the assembly member is low, so that concentrated load occurs, and durability is not guaranteed when used for a long period of time. In addition, in the case of the conventional assembly-type vibration isolation stand (1000a), in order to improve the durability and quality of the vibration isolation plate (100a) itself, a large number of reinforcing bars must be placed inside the square frame (10a), but since a large number of reinforcing bars are provided, the manufacturing process takes a long time.

Accordingly, the present invention aims to improve the durability of the connection between a damping plate and an assembly member by integrating the damping plate and the assembly member, increase the rigidity of the damping plate itself, and reduce the amount of reinforcing bars used in manufacturing the damping plate, thereby shortening the manufacturing period.

That is, the dry assembly type damping plate of the present invention has the advantage of significantly improving the rigidity of the joint portion between the damping plate and the assembly member, thereby greatly improving the strength against a concentrated load applied to the joint portion, greatly improving the rigidity of the damping plate itself, and reducing the difficulty of the manufacturing process and shortening the manufacturing period.

Hereinafter, the structure of a dry assembly type vibration isolation device capable of dry assembly according to the present invention will be specifically described with reference to FIGS. 4 to 14.

The dry assembly type vibration isolation board (1000) of the present invention is a structure in which a plurality of vibration isolation plates (100) manufactured to a set standard are dry-assembled at a site, and a plurality of vibration isolation plates (100) are provided in a grid shape inside a square frame (110) of a set standard, and concrete is poured to a set thickness above and below the reinforcement bars, so that they can be interconnected at the site.

In the case of the seismic plate (100), the square frame (110) is basically a rectangular frame made of metal material with a known configuration, and can be manufactured in various sizes and shapes depending on the installation location. H-shaped steel (120) and reinforcing bars (130) are arranged inside the square frame (110), and concrete (140) is poured to accommodate the H-shaped steel (120) and reinforcing bars (130) arranged inside the square frame (110), thereby forming reinforced concrete.

In this case, at least a part of the H-shaped steel (120) may be provided to protrude outward from one side of the square frame (110) forming the outer wall of the damping plate (100). That is, at least a part of the H-shaped steel (120) protrudes outward from one side of the square frame (110). The part of the H-shaped steel (120) protruding outward serves as an assembly member (121) that connects or joins each damping plate (100). That is, the assembly member (121) may correspond to at least a part of the H-shaped steel (120), and the H-shaped steel (120) is placed inside the square frame (110) with the assembly member (121) protruding outward and is poured with concrete.

Referring to Fig. 4, the first damping plate (100a) and the second damping plate (100b) can be manufactured separately, and the first damping plate (100a) and the second damping plate (100b) can be connected through the connection between the assembly members (121) of each damping plate. Each assembly member formed on each damping plate can be connected by one or more connecting plates (200). For example, each assembly member and one or more connecting plates (200) have holes formed so that they can be fastened by bolts, and each assembly member is connected by connecting each hole of the bolt while being aligned and communicating with each hole.

The attached drawing shows a pair of damping plates (100) being joined together and an assembly member (121) being formed on one side of the damping plate (100), but in an actual product, the assembly members (121) may be formed on each of two sides, three sides, or four sides of the damping plate (100), so that a plurality of damping plates (100) may be joined in a side selected from the front, back, left, and right.

According to one embodiment of the present invention, the damping plate (100) may include a square frame (110). The square frame (110) may have a shape of a square frame and may form a side wall of the damping plate (100). The square frame (110) is basically a rectangular frame made of metal and may be manufactured in various sizes and shapes depending on the installation location. H-shaped steel (120) and reinforcing bars (130) are arranged inside the square frame (110), and concrete is poured, thereby forming a reinforced concrete, i.e., a damping plate (100). Accordingly, when the damping plate (100) is formed, the square frame (110) may form a side wall of the damping plate (100) and may include H-shaped steel (120), reinforcing bars (130), and concrete (140) inside.

In one embodiment, at least one surface of the square frame (110) may be formed with one or more connecting grooves (111a). Specifically, as illustrated in FIG. 5, the first surface (111) of the square frame (110) may be provided with one or more connecting grooves (111a) that penetrate through the H-shaped steel (120). The one or more connecting grooves (111a) refer to grooves through which the H-shaped steel (120) penetrates, and are provided in a shape corresponding to the cross-section of the H-shaped steel (120). That is, as illustrated in FIG. 5, the one or more connecting grooves (111a) may refer to H-shaped grooves. One or more H-shaped steels (120) may penetrate and fit into each of the one or more connecting grooves (111a).

The square frame (110) is a square-shaped frame, and is configured by a first surface (111) on which one or more connecting grooves (111a) are formed, a second surface (112) parallel to the first surface (111), and two longitudinal surfaces (113) vertically connecting the first surface (111) and the second surface (112). The two longitudinal surfaces (113) can be perpendicular to the first surface (111) and the second surface (112), respectively.

According to one embodiment, the H-shaped steel (120) may be a steel having an H-shaped cross section. The H-shaped steel is composed of a wide and thick flange and a thin web, has excellent cross-sectional performance, and is easy to assemble and join, so it is used as structural steel.

In an embodiment, at least a portion of the H-shaped steel (120) may be characterized by forming an assembly member (121). Specifically, as illustrated in FIG. 6, an assembly member (121) may be formed at one end of the H-shaped steel (120). In an embodiment, the assembly member (121) may be provided to protrude in the outward direction of the square frame (110) as a structure for connection or combination with another damping plate (100).

According to one embodiment, the assembly member (121) may include a pair of horizontal plates (121a) that are parallel and a vertical plate (121b) that vertically connects the horizontal plates (121a), as illustrated in FIGS. 6 and 7. Each of the horizontal plates (121a) and the vertical plates (121b) may be characterized by having a plurality of perforations formed therein for coupling with one or more connecting plates (200). Specifically, each of the horizontal plates (121a) may be provided with a first coupling hole (121a-1), and the vertical plate (121b) may be provided with a second coupling hole (121b-1). In the embodiment, the first coupling hole (121a-1) and the second coupling hole (121b-1) may be perforations formed at positions or intervals corresponding to the plurality of perforations provided in each of the one or more connecting plates (200).

In a specific embodiment, the H-shaped steel (120) may be characterized by being provided with a first length (120-1). Here, the first length (120-1) may be characterized by being longer than the second length corresponding to the length (113) of the square frame (110).

In an embodiment, the longitudinal side (113) of the square frame (110) may mean a side that is vertically connected to one side (i.e., the first side (111)) provided with a connecting groove (111a). Specifically, referring to FIG. 5, two sides connecting the first side (111) on which one or more connecting grooves (111a) are formed and the second side (112) that is parallel to the first side (111) may be the longitudinal side (113).

Since the H-shaped steel (120) is provided with a first length that is greater than a second length corresponding to the longitudinal surface (113), at least a portion thereof may protrude outside the square frame (110). Here, a portion of the H-shaped steel (120) that protrudes outside the square frame (110) may be an area where an assembly member (121) is formed.

Referring to FIGS. 5 to 7, more specifically, one end of the H-shaped steel (120) is inserted into and fitted into a connecting groove (111a) formed on the first surface (111) of the square frame (110), so that at least a portion of the H-shaped steel (120) is positioned on the inside of the square frame (110).

In this case, since the length of the H-shaped steel (120) (i.e., the first length) is greater than the length of the longitudinal side of the square frame (110) (i.e., the second length), when one end of the H-shaped steel (120) comes into contact with the second side (112), the other end of the H-shaped steel (120) (i.e., the end corresponding to the area where the assembly member (121) is formed) is positioned on the outside of the square frame (110). That is, a part of the H-shaped steel (120) positioned on the outside of the square frame (110) based on the connecting groove (111a) may be an assembly member (121) that performs the role of connecting each damping plate (100).

That is, when one end of the H-shaped steel (120) comes into contact with the second surface (112), the assembly member (121) formed on the other end of the H-shaped steel (120) may be provided so as to protrude outward from the square frame (110).

The assembly member (121) may be configured with a pair of horizontal plates (121a) that are formed parallel and have a plurality of first joining holes (121a-1) and a vertical plate that vertically connects the horizontal plates (121a) and has a plurality of second joining holes (121b-1) formed, so that the cross section may be H-shaped.

As shown in FIGS. 4, 7, and 9, a plurality of such assembly members (121) may be provided vertically along the side wall of the damping plate (100). Although the above drawing illustrates six assembly members (121), it will be apparent to those skilled in the art that the number may be increased or decreased depending on various implementation aspects of the present invention (e.g., the size of the damping plate).

According to an embodiment, the damping plate (100) may include reinforcing bars (130) arranged on the inside of a square frame (110) and concrete (140) poured above and below the H-shaped steel (120) and reinforcing bars (130) in the inner direction of the square frame (110).

Specifically, as illustrated in FIG. 7, one or more H-shaped steel bars (120) may be inserted into each of one or more connecting grooves (111a) formed in a square frame (110), thereby positioning a portion of the H-shaped steel bars (120) inside the square frame (110). In this case, reinforcing bars are arranged inside the square frame (110) together with the H-shaped steel bars (120).

With a portion of H-shaped steel (120) and reinforcing bars (130) provided inside a square frame (110), concrete (140) is poured, and accordingly, a vibration damping plate (100) corresponding to the reinforced concrete is formed, as shown in FIG. 9.

As described above, since the H-shaped steel (120) having a relatively wider thickness than the reinforcing bar (130) and excellent durability is provided inside the body of the vibration damping plate (100), the concrete joint cross-sectional area inside the body is greatly expanded, so that the rigidity of the vibration damping plate body itself can be greatly improved. In addition, the amount of reinforcing bar placed inside the body of the vibration damping plate (100) is reduced through the H-shaped steel (120).

In various embodiments, when the H-shaped steel (120) is provided to penetrate the connecting groove (111a) of the square frame (110), it may be characterized in that a fixed connection between the H-shaped steel (120) and the square frame (110) is performed. Specifically, as the H-shaped steel (120) is fitted into the connecting groove (111a), at least a portion of it is provided on the inner side of the square frame (110). In this case, a joining process for fixing the H-shaped steel (120) and the square frame (110) may be performed. In a specific embodiment, as illustrated in FIG. 8, the joining process between the H-shaped steel (120) and the square frame (110) may be performed corresponding to each of the first region (111-1) and the second region (112-1). For example, the joining process may mean a joining process through welding. Here, the first region (111-1) may mean a region corresponding to the first surface (111) of the square frame (110) provided with the connecting groove (111a), and the second region (112-1) may mean a region corresponding to the second surface (112) of the square frame (110) that contacts one end of the H-shaped steel (120) inserted through the connecting groove (111a). That is, when one end of the H-shaped steel (120) is inserted and fitted into the connecting groove (111a), a joining process may be performed on the second region (112-1) corresponding to the second surface (112) of the square frame (110) that contacts one end of the H-shaped steel (120) and the first region (111-1) corresponding to the first surface of the square frame (110) that supports the H-shaped steel (120). Through this bonding process, even if reinforcing bars and concrete are injected into the inside of the square frame (110), the position of the H-shaped steel (120) may not be distorted, and furthermore, the H-shaped steel (120) may be more firmly fixed to the damping plate (100), so that the stability of the connection portion between the damping plates (100) may be further improved.

As described above, a part of the H-shaped steel (120) is fixed to the inside of the square frame (110), and only the assembly member (121) area may be provided to protrude outside the square frame (110). That is, the assembly member (121) is not provided in a form that is simply joined to one surface of the damping plate (100) by welding or the like, but is provided in a form that extends from the inside of the damping plate (100). This increases the stability of the joint between each damping plate and the assembly member, thereby ensuring improved durability against various impacts, thereby improving the stability of the device.

In addition, since H-shaped steel (120) with a relatively wider thickness than the reinforcing bar (130) and excellent durability is provided inside the body of the vibration damping plate (100), the cross-sectional area of the concrete joint inside the body is greatly expanded, so that the rigidity of the vibration damping plate body itself can be increased, which has the advantage of maximizing the vibration reduction performance, which is the main function of the vibration damping plate.

Additionally, the amount of reinforcing bar arrangement process during the manufacture of the damping plate can be drastically reduced through the use of H-shaped steel (120), thereby simplifying the damping plate production process.

In an embodiment, a plurality of damping plates (100) may be characterized in that they are indirectly connected via one or more connecting plates (200). A plurality of damping plates (100) may be characterized in that they are connected via assembly members (121) provided on each, but are indirectly connected via the connecting plates (200).

According to one embodiment, the assembly member (121) may include a pair of horizontal plates (121a) that are parallel and a vertical plate (121b) that vertically connects the horizontal plates (121a), as illustrated in FIGS. 6 and 7. Each of the horizontal plates (121a) and the vertical plates (121b) may be characterized by having a plurality of perforations formed therein for coupling with one or more connecting plates (200). Specifically, each of the horizontal plates (121a) may be provided with a first coupling hole (121a-1), and the vertical plate (121b) may be provided with a second coupling hole (121b-1). In the embodiment, the first coupling hole (121a-1) and the second coupling hole (121b-1) may be perforations formed at positions or intervals corresponding to the plurality of perforations provided in each of the one or more connecting plates (200).

In an embodiment, one or more connecting plates (200) may include a first connecting plate (210) that contacts the horizontal plate (121a) of each assembly member and a second connecting plate (220) that contacts the vertical plate (121b) of each assembly member. One or more connecting plates (200) may be in contact with the assembly member (121), and when fastening is performed through the bolting portion (300) in a state where one or more connecting plates (200) are in contact with the assembly member (121), a coupling or connection between the assembly members (121) may be performed.

In various embodiments, the dry assembly damping member may further include a bolting member (300) that is sequentially connected by penetrating a joining hole formed in each of the assembly members of each of the plurality of damping plates and a joining hole formed in each of one or more connecting plates.

Referring to Fig. 10 for more detailed explanation, each damping plate is connected to one or more connecting plates (200) in a state where the ends of each assembly member (i.e., the first assembly member (121-1) and the second assembly member (121-2)) formed on each surface face each other. In this case, it is preferable that each assembly member is spaced apart by a predetermined interval for smooth damping characteristics.

The first connecting plate (210) can be in contact with the outer side of each of the horizontal plates (121a) of the first assembly member (121-1) and the second assembly member (121-2). That is, with reference to FIG. 10, the first connecting plate (210) can be in contact with each of the upper surface of the upper horizontal plate (121a) and the lower surface of the lower horizontal plate (121a). In this case, the first connecting plate (210) can be provided with a third connecting hole (211) corresponding to the first connecting hole (121a-1) formed in each of the first assembly member (121-1) and the second assembly member (121-2).

In addition, the second connecting plate (220) can be brought into contact with both sides of the vertical plates (121b) of each of the first assembly member (121-1) and the second assembly member (121-2). That is, two second connecting plates (220) come into contact with both sides of the vertical plates (121b) corresponding to the first assembly member (121-1) and the second assembly member (121-2). In this case, the second connecting plate (220) can be provided with a fourth connecting hole (221) corresponding to the second connecting hole (121b-1) formed in each of the first assembly member (121-1) and the second assembly member (121-2).

In addition, when the first connecting plate (210) and the second connecting plate (220) are in contact with each assembly member, the bolting member (300) is connected in sequence through the holes formed in each assembly member and the connecting plate, thereby connecting the assembly members and each connecting plate. That is, the first assembly member (121-1) and the second assembly member (121-2) can be fixedly connected by being connected to two first connecting plates (210) and two second connecting plates (220).

That is, referring to Fig. 11 as an example of a connection between one assembly member (121) and one or more connecting plates (200), a first connecting plate (210) is formed on the outside of a horizontal plate (121a) that is parallel to each other, and a second connecting plate (220) is formed on each side of a vertical plate (121b), and a third connecting hole (211) corresponding to the first connecting hole (121a-1) is formed on the first connecting plate (210), and a fourth connecting hole (221) corresponding to the second connecting hole (121b-1) is formed on the second connecting plate (220). The bolting part (300) can be fastened to both the third connecting hole (211) connected to the first connecting hole (121a-1) and the fourth connecting hole (221) connected to the second connecting hole (121b-1), and through this process, the assembly members corresponding to the two damping plates are connected.

When connecting such assembly members, it is preferable to first connect the second connection plate (220) to both sides of the adjacent vertical plates (121b), and then connect the first connection plate (210) to the outside of the upper and lower horizontal plates (121a). It is also preferable to configure the width of the first connection plate (210) to be relatively narrower than the width of the horizontal plate (121a), and to sufficiently secure the spacing between the assembly members (121) so that a tool for bolting the first connection plate (210), i.e., connecting a bolt and nut, can sufficiently pass through the space between them. The above-described structure has the advantage of providing improved reinforcing capacity in response to external forces in the up-down, left-right, and front-back directions due to the symmetrical structure of the assembly members in the up-down and left-right directions. That is, through the H-beam-shaped structure as described above, the connection strength (or bonding strength) of the joints (i.e., between the assembly members) of each vibration damping plate (100) is improved, thereby securing high rigidity of the vibration damping table.

FIG. 12 is a flow chart exemplarily showing a method for manufacturing a dry assembly type vibration isolation platform according to one embodiment of the present invention. According to one embodiment of the present invention, the method for manufacturing a dry assembly type vibration isolation platform may be composed of the following steps. The order of the steps illustrated in FIG. 12 may be changed as necessary, and at least one or more steps may be omitted or added. That is, the following steps are merely one embodiment of the present invention, and the scope of the rights of the present invention is not limited thereto.

According to one embodiment, a method for manufacturing a dry assembly damper may include a step (S110) of providing a square frame (110).

The square frame (110) may have a rectangular frame shape and may form a side wall of the damping plate (100). The square frame (110) is basically a rectangular frame made of metal and may be manufactured in various sizes and shapes depending on the installation location. H-shaped steel (120) and reinforcing bars (130) may be arranged inside the square frame (110), and as concrete is poured, reinforced concrete, i.e., the damping plate (100), may be formed. Accordingly, when the damping plate (100) is formed, the square frame (110) may form a side wall of the damping plate (100) and may include H-shaped steel (120), reinforcing bars (130), and concrete (140) inside.

In one embodiment, at least one surface of the square frame (110) may be formed with one or more connecting grooves (111a). Specifically, the first surface (111) of the square frame (110) may be provided with one or more connecting grooves (111a) that penetrate through the H-shaped steel (120). The one or more connecting grooves (111a) refer to grooves through which the H-shaped steel (120) penetrates, and are provided in a shape corresponding to the cross section of the H-shaped steel (120). One or more H-shaped steels (120) may be inserted into each of the one or more connecting grooves (111a).

The square frame (110) is a square-shaped frame, and is configured by a first surface (111) on which one or more connecting grooves (111a) are formed, a second surface (112) parallel to the first surface (111), and two longitudinal surfaces (113) vertically connecting the first surface (111) and the second surface (112). The two longitudinal surfaces (113) can be perpendicular to the first surface (111) and the second surface (112), respectively.

According to one embodiment, a method for manufacturing a dry assembly damper may include a step (S120) of providing one or more H-shaped steel members through one side of a square frame (110).

In a specific embodiment, the step of providing one or more H-shaped steel bars (120) by penetrating through one surface of a square frame (110) may include the steps of inserting one end of the H-shaped steel bars (120) into a first surface where a connecting groove (111a) is formed, bringing one end of the H-shaped steel bars (120) into contact with a second surface parallel to the first surface, and performing a joining process for a first area (111-1) corresponding to the connecting groove (111a) that comes into contact with the H-shaped steel bars (120) and a second area (112-1) corresponding to one surface that comes into contact with one end of the H-shaped steel bars (120).

Specifically, when the H-shaped steel (120) is provided by penetrating the connecting groove (111a) of the square frame (110), it may be characterized in that a fixed connection between the H-shaped steel (120) and the square frame (110) is performed. Specifically, as the H-shaped steel (120) is fitted into the connecting groove (111a), at least a portion of it is provided on the inside of the square frame (110). In this case, a joining process for fixing the H-shaped steel (120) and the square frame (110) may be performed. In a specific embodiment, as illustrated in FIG. 8, the joining process between the H-shaped steel (120) and the square frame (110) may be performed corresponding to each of the first region (111-1) and the second region (112-1). For example, the joining process may mean a joining process through welding. Here, the first region (111-1) may mean a region corresponding to the first surface (111) of the square frame (110) provided with the connecting groove (111a), and the second region (112-1) may mean a region corresponding to the second surface (112) of the square frame (110) that contacts one end of the H-shaped steel (120) inserted through the connecting groove (111a). That is, when one end of the H-shaped steel (120) is inserted and fitted into the connecting groove (111a), a joining process may be performed on the second region (112-1) corresponding to the second surface (112) of the square frame (110) that contacts one end of the H-shaped steel (120) and the first region (111-1) corresponding to the first surface of the square frame (110) that supports the H-shaped steel (120). Through this bonding process, even if reinforcing bars and concrete are injected into the inside of the square frame (110), the position of the H-shaped steel (120) may not be distorted, and furthermore, the H-shaped steel (120) may be more firmly fixed to the damping plate (100), so that the stability of the connection portion between the damping plates (100) may be further improved.

According to one embodiment, a method for manufacturing a dry-type prefabricated vibration damper may include a step (S130) of arranging reinforcing bars inside a square frame in which one or more H-shaped steel beams are positioned.

Specifically, one or more H-shaped steel bars (120) can be inserted into each of one or more connecting grooves (111a) formed in the square frame (110), and thus, a part of the H-shaped steel bars (120) is positioned inside the square frame (110). In this case, reinforcing bars (130) are arranged together with the H-shaped steel bars (120) inside the square frame (110). As described above, since the H-shaped steel bars (120) having a relatively wider thickness than the reinforcing bars (130) and superior durability are arranged inside the body of the vibration damping plate (100), the concrete joint cross-sectional area inside the body is greatly expanded, and thus the rigidity of the body of the vibration damping plate itself can be greatly improved. In addition, the amount of reinforcing bars arranged inside the body of the vibration damping plate (100) is reduced through the H-shaped steel bars (120).

According to one embodiment, a method for manufacturing a dry prefabricated vibration damping plate may include a step (S140) of forming a vibration damping plate (100) by pouring concrete into the inside of a square frame (110).

With a portion of H-shaped steel (120) and reinforcing bars (130) provided inside a square frame (110), concrete (140) is poured, and accordingly, a vibration damping plate (100) corresponding to the reinforced concrete is formed.

As described above, at least a portion of the H-shaped steel (120) is fixed to the inside of the square frame (110), and only the area of the assembly member (121) may be provided so as to protrude to the outside of the square frame (110). That is, the assembly member (121) is not provided in a form that is simply joined to one surface of the damping plate (100) by welding or the like, but is provided in a form that extends from the inside of the damping plate (100). This increases the stability of the joint between each damping plate and the assembly member, thereby ensuring improved durability against various impacts, thereby improving the stability of the device.

According to one embodiment, a method for manufacturing a dry assembly-type vibration damping plate may include a step (S150) of interconnecting a plurality of vibration damping plates (100) to create an assembly-type vibration damping plate (1000).

Specifically, the step of interconnecting a plurality of damping plates (100) to create an assembled damping table (1000) may include a step of contacting one or more connecting plates (200) between assembly members (121) of adjacent pairs of damping plates, and a step of sequentially connecting the assembly members of each damping plate and one or more connecting plates by passing through joint holes formed in each of the assembly members (121) and the connecting plates through bolting members (300) while the assembly members of each damping plate and each of the one or more connecting plates are in contact.

More specifically, the step of contacting at least one connecting plate (200) between the assembly members (121) of an adjacent pair of damping plates may include the step of contacting a first connecting plate (210) in which a third connecting hole (211) corresponding to a first connecting hole is formed on an outer side of each of the adjacent horizontal plates (121a) in a state in which the ends of the assembly members of the adjacent pair of damping plates face each other, and the step of contacting a second connecting plate (220) in which a fourth connecting hole (221) corresponding to a second connecting hole (121b-1) is formed on each of both sides of the adjacent vertical plates (121b).

Each damping plate is connected to one or more connecting plates (200) in a state where the ends of each assembly member (i.e., the first assembly member (121-1) and the second assembly member (121-2) formed on each surface face each other. In this case, it is preferable that each assembly member is spaced apart by a predetermined interval for smooth damping characteristics.

The first connecting plate (210) can be in contact with the outer side of each of the horizontal plates (121a) of the first assembly member (121-1) and the second assembly member (121-2). That is, with reference to FIG. 10, the first connecting plate (210) can be in contact with each of the upper surface of the upper horizontal plate (121a) and the lower surface of the lower horizontal plate (121a). In this case, the first connecting plate (210) can be provided with a third connecting hole (211) corresponding to the first connecting hole (121a-1) formed in each of the first assembly member (121-1) and the second assembly member (121-2).

In addition, the second connecting plate (220) can be brought into contact with both sides of the vertical plates (121b) of each of the first assembly member (121-1) and the second assembly member (121-2). That is, two second connecting plates (220) come into contact with both sides of the vertical plates (121b) corresponding to the first assembly member (121-1) and the second assembly member (121-2). In this case, the second connecting plate (220) can be provided with a fourth connecting hole (221) corresponding to the second connecting hole (121b-1) formed in each of the first assembly member (121-1) and the second assembly member (121-2).

In addition, when the first connecting plate (210) and the second connecting plate (220) are in contact with each assembly member, the bolting member (300) is connected in sequence through the holes formed in each assembly member and the connecting plate, thereby connecting the assembly members and each connecting plate. That is, the first assembly member (121-1) and the second assembly member (121-2) can be fixedly connected by being connected to two first connecting plates (210) and two second connecting plates (220).

That is, referring to Fig. 11 as an example of a connection between one assembly member (121) and one or more connecting plates (200), a first connecting plate (210) is in contact with the outside of a horizontal plate (121a) that is parallel to each other, and a second connecting plate (220) is in contact with each of both sides of a vertical plate (121b). A third connecting hole (211) corresponding to the first connecting hole (121a-1) is formed in the first connecting plate (210), and a fourth connecting hole (221) corresponding to the second connecting hole (121b-1) is formed in the second connecting plate (220). The bolting portion (300) can be fastened to both the third connecting hole (211) that is connected to the first connecting hole and the fourth connecting hole that is connected to the second connecting hole (121b-1), and through this process, the assembly members corresponding to both damping plates are connected.
