Description

[DESCRIPTION] [Invention Title] STEEL PLATE STRUCTURE AND STEEL PLATE CONCRETE WALL
[Technical Field]
The present invention relates to a steel plate structure and a steel plate concrete wall. More particularly, the present invention relates to a steel plate structure and a steel
- plate concrete wall that can effectively exhaust vapor created by high levels of heat created inside the steel plate concrete wall and reduce the thickness of both the steel plate concrete wall and the steel plates.
[Background Art]
As structures become taller and larger, it is becoming more important to provide higher strength and improved workability. For reinforced concrete structures, steel frame structures, steel framed reinforced concrete structures, etc., which have been in common use, a structure may be constructed by assembling mold forms and steel bars or steel frames, etc., and casting the concrete directly at the construction site, inevitably prolonging the construction times and lowering the reliability of quality. Receiving attention as an alternative to such structures is the steel plate concrete structure (hereinafter referred to as "SC structure"), which is made by filling concrete on the inside of steel plates and provides desirable properties in terms of strength, load-bearing, strain characteristics, workability, etc. The SC structure can be made by filling in concrete between two steel plates and arranging studs, tie bars, etc., for keeping the concrete and the steel materials moving together, so that the steel plates and the concrete may move as an integrated body. In particular, the SC structure can be utilized in the construction of large-scale structures, such as nuclear power plants, etc., by using modularization to reduce construction times.
When using an SC structure, even if the load causes the inside concrete to reach its failure point, the steel plates may continue to restrict the concrete, so that a greater level of load-bearing may be provided. Also, as the concrete is placed on the inside of the steel plates, the concrete can be prevented from being degraded by the external environment, so that the durability of the structure may be improved.
Figure 1 is a perspective view of a steel plate structure according to the related art before casting concrete. In the descriptions that follow, the steel composition made of steel plates, etc., before casting the concrete to form an SC structure wall, will be referred to as a "steel plate structure." An SC structure wall using steel plate structures according to the related art may be constructed by vertically positioning steel plates 102 on both sides of the wall that is to be formed, connecting the steel plates 102 by using tie bars 106 shaped as steel rods for securing the steel plates 102, and then casting concrete in the space inside the steel plates 102. Here, numerous studs 104 may be formed on the inner surfaces of the steel plates 102 for better adhesion between the steel plates 102 and the concrete.
In an SC structure wall for skyscrapers, nuclear power plants, etc., formed using steel plate structures according to the related art, the high levels of heat created in the event of a fire may evaporate the moisture in the concrete and increase the vapor pressure inside the SC structure wall. The vapor pressure may not be effectively displaced to the outside by the steel plates on the outside of the SC structure, causing the steel plates to expand and damaging the wall.
In particular, when the SC structure wall is used in high-temperature environments, such as in nuclear power plants, etc., the vapor pressure in the concrete may generate thermal stresses inside the concrete, creating a risk of cracks forming in the concrete.
Also, when forming SC structure walls for large-scale constructions, such as skyscrapers, nuclear power plants, etc., by using steel plate structures according to the related art, spatial limitations may be increased, due to the increases in thickness of the SC structure walls.
Furthermore, in order to support large loads, the thicknesses of the steel plates and concrete may need to be increased. However, an increase in the thickness of the steel plates may entail an increase in thermal deformations when welding the steel plates together, and may necessitate thermal post-treatment. In particular, a structure for a skyscraper or a nuclear power plant may have to effectively withstand axial forces caused by the self- weight of the structure as well as lateral forces caused by earthquakes.
Since the concrete within the steel members has low shear strength, the remaining shear stresses that are not borne by the concrete may have to be withstood by the steel plates. Thus, to withstand the shear stresses from lateral forces caused by earthquakes, the thickness of the steel plates may have to be increased.
[Disclosure] [Technical Problem] An aspect of the present invention is to provide a steel plate structure and a steel plate concrete wall that can readily displace vapor in the concrete created by high levels of heat.
Another aspect of the present invention is to provide a steel plate structure and a steel plate concrete wall that include structural members for supporting loads together with the steel plates and the concrete, making it possible to reduce the thickness of the steel plate concrete wall and the thickness of the steel plates, as well as to effectively withstand axial and lateral forces applied on the wall.
[Technical Solution]
One aspect of the present invention provides a steel plate structure for forming a wall by casting concrete therein. The steel plate structure may include: a pair of steel plates that are separated from each other with one side of one steel plate facing one side of the other steel plate such that a space is defined in-between, a strut maintaining a distance between the pair of steel plates, and a perforated pipe positioned in the space that extends from one end of the space to the other end of the space and has a multiple number of holes formed therein.
The steel plate structure can further include an insertion rod inserted in the perforated pipe.

However, this is not intended to limit the present invention to particular modes of practice, and it is to be appreciated that all changes, equivalents, and substitutes that do not depart from the spirit and technical scope of the present invention are encompassed in the present invention. In the description of the present invention, certain detailed descriptions of related art are omitted when it is deemed that they may unnecessarily obscure the essence of the present invention.
The terms used in the present specification are merely used to describe particular embodiments, and are not intended to limit the present invention. An expression used in the singular encompasses the expression of the plural, unless it has a clearly different meaning in the context. In the present specification, it is to be understood that the terms such as "including" or "having," etc., are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof disclosed in the specification, and are not intended to preclude the possibility that one or more other features, numbers, steps, actions, components, parts, or combinations thereof may exist or may be added.
The steel plate structure and steel plate concrete wall according to certain embodiments of the invention will be described below in more detail with reference to the accompanying drawings. Those components that are the same or are in correspondence are rendered the same reference numeral regardless of the figure number, and redundant descriptions are omitted.
Figure 2 is a perspective view of a steel plate structure according to a first disclosed embodiment of the present invention, and Figure 3 is a side view illustrating a portion of a steel plate structure according to the first disclosed embodiment of the present invention while Figure 4 is a perspective view illustrating a portion of a steel plate structure according to the first disclosed embodiment of the present invention. Illustrated in Figure 2 through Figure 4 are a steel plate structure 10, steel plates 12, struts 16, studs 18, perforated pipes 17, and an insertion rod 19.
A steel plate structure 10 according to the present embodiment may be a steel plate structure for forming a wall by casting concrete within. The steel plate structure 10 may be composed mainly of: a pair of steel plates 12 that are separated, with one side of one steel plate facing one side of the other steel plate, such that a certain space is defined in-between; one or more struts 16 that maintain a distance between the pair of steel plates 12; and one or more perforated pipes 17 positioned in the space that extend from one end to the other end of the space and include numerous holes formed therein.
The steel plate structure 10 can effectively displace vapor created in the steel plate concrete wall by high levels of heat, to prevent the steel plate concrete wall from expanding or bursting and to improve durability.
The pair of steel plates 12 may be separated, each with one side facing each other, to define a particular space between the steel plates 12. This space is where the concrete is to be cast in later, and the distance between the steel plates 12 can be determined in accordance with the load that will be applied on the steel plate concrete wall. When the wall is formed, the steel plates 12 will be integrated with the concrete to withstand the load. Also, the steel plates 12 may restrict the concrete after the concrete reaches its failure point, to thereby increase the load-bearing capacity of the steel plate concrete wall.
The struts 16 may maintain a distance between the steel plates 12, so that the pair of steel plates 12 may provide the space in-between. A strut 16 can have both ends coupled respectively to the pair of steel plates 12, respectively, to maintain the distance between the steel plates 12.
The struts 16 may maintain the distance between the steel plates 12 in consideration of the thickness of the wall, and may provide sufficient rigidity in consideration of operations for transporting the steel plate structure 10, etc. hi the case of a wall for a large-scale structure, the large thickness of the wall may require a large distance between the two steel plates 12, and thus steel beams having high rigidity may be used for the struts 16.
Various types of structural material, such as steel rods, L-beams, C-beams, H-beams, I-beams, T-beams, etc., can be used for the struts 16. This particular embodiment presents an example in which steel rod type struts 16 are used.
The perforated pipes 17 may be positioned within the space defined by the pair of steel plates 12 and may extend from one end to the other end of the space. The perforated pipes 17 may include numerous holes formed along their perimeters.
A steel plate concrete structure may experience an increase in vapor pressure when the moisture in the concrete is turned into vapor due to high levels of heat. As the steel plates of the steel plate concrete structure hinder the effective displacement of such vapor, the steel plates may expand and cause damage to the wall. In particular, since steel plate concrete walls used in a nuclear power plant may be subject to a high-temperature environment, the vapor pressure of the concrete can create thermal stresses within the concrete, creating a risk of cracks forming in the concrete.
Thus, in order to effectively displace the vapor created in the concrete to the exterior, perforated pipes 17 having numerous holes may be positioned within the space formed by the steel plates 12. For example, the perforated pipes 17 can be joined to one side of a steel plate 12, as illustrated in Figure 2, or coupled to the studs 18 to be arranged inside the space, as illustrated in Figure 7.
The perforated pipes 17 may extend from one end to the other end of the space defined by the pair of steel plates 12. Thus, if the steel plate structure 10 is used as a unit module and a wall is to be formed by assembling multiple unit modules, the perforated pipes 17 of the unit modules may be interconnected.
While the present embodiment has been described using an example in which the perforated pipes 17 are arranged vertically to displace the vapor created in the concrete through the top and bottom of the steel plate concrete wall, it is also possible to arrange the perforated pipes 17 horizontally to displace the vapor through the left and right of the steel plate concrete wall. Of course, the perforated pipes 17 may be arranged in a variety of different forms, such as in diagonal directions.
Holes may be formed in the perimeters of the perforated pipes 17, so that when vapor is created inside the steel plate concrete wall due to high levels of heat, the vapor may enter the perforated pipes 17 through the many holes formed in the perforated pipes
17, while the vapor that has entered the perforated pipes 17 may move through the perforated pipes 17 to be displaced to the exterior.
The steel plate structure 10 according to the present embodiment can further include insertion rods 19 that are inserted through the perforated pipes 17. When forming a steel plate concrete wall by casting concrete inside the steel plate structure 10, the insertion rods 19 may prevent unhardened concrete from flowing into the perforated pipes 17. When the concrete is cured to a certain degree of hardness after the concrete is cast, the insertion rods 19 may be pulled out, as illustrated in Figure 4. The steel plate structure 10 according to the present embodiment can also include studs 18 that are coupled as protrusions from one side of the steel plate 12. The studs 18 may be embedded in the concrete, to allow the steel plates 12 and the concrete to move as an integrated body, so that the combined effect of the steel plates 12 and concrete may withstand external loads. The studs 18 can be arranged uniformly over the steel plates 12 such that the concrete and steel plates 12 are integrated over the entire area.
Figure 5 is a perspective view illustrating steel plate structures joined together according to the first disclosed embodiment of the present invention, and Figure 6 is a perspective view illustrating the coupling of perforated pipes according to the first disclosed embodiment of the present invention. Illustrated in Figure 5 and Figure 6 are steel plate structures 10, steel plates 12, struts 16, studs 18, perforated pipes 17, and a sleeve 21.
A steel plate structure 10 according to the present embodiment can form a unit module. After manufacturing numerous unit modules in a factory, the unit modules can be joined together on site to form a wall. It is also possible to form steel plate concrete walls by assembling many unit modules of steel plate structures 10 to fabricate one large module, hoisting and installing the large module in the final position, and then casting concrete therein. The unit modules, i.e. steel plate structures 10, can be coupled together by welding adjacent steel plates 12 to each other or by adding reinforcing plates and fastening with high-tension bolts or rivets. In such cases, the perforated pipes 17 of adjacent steel plate structures 10 may be interconnected, so that vapor may move through the perforated pipes 17 and be displaced to the exterior.
As illustrated in Figure 6, the perforated pipes 17 can be interconnected by way of sleeves 21, into which the end portions of the perforated pipes may be inserted. It is also possible to screw-join the perforated pipes 17, by forming a male thread in the end portion of one perforated pipe 17 and forming a female thread in the end portion of the perforated pipe 17 being joined.
Figure 7 is a side view illustrating a steel plate structure according to a second disclosed embodiment of the present invention. Illustrated in Figure 7 are steel plates 12, struts 16, perforated pipes 17, and studs 18.
A steel plate concrete wall may be formed by casting concrete in the steel plate structure, but if the wall is thick, the perforated pipes 17 installed at the end portions of the wall may not be sufficient for effectively displacing vapor inside the concrete. Thus, as illustrated in Figure 7, many perforated pipes 17 can be arranged in the space defined by the pair of steel plates 12, in addition to those arranged at the end portions of the steel plate structure, so that the vapor created in the concrete may be displaced more easily.
The number of perforated pipes 17 formed in the steel plate concrete wall may vary as necessary, according to the thickness of the wall.
The other components of the present embodiment are substantially the same as those described above, and thus will not be described again.
Figure 8 is a perspective view illustrating a steel plate structure according to a third disclosed embodiment of the present invention, and Figure 9 is a perspective view illustrating steel plate structures joined together according to the third disclosed embodiment of the present invention. Illustrated in Figure 8 and Figure 9 are steel plate structures 10, steel plates 12, structural members 14, struts 16, perforated pipes 17, and studs 18.
A steel plate structure 10 according to the present embodiment may include: a pair of steel plates 12 that are separated, with one side of one steel plate facing one side of the other steel plate, such that a certain space is defined in-between; one or more struts 16 that maintain a distance between the pair of steel plates 12; one or more perforated pipes 17 positioned in the space that extend from one end to the other end of the space and include numerous holes formed therein; and one or more structural members 14 that are positioned in the space and structurally rigidly joined to one side of the steel plate 12 along a direction of gravity. The structural members 14 may be located in the space formed by the pair of steel plates 12, and may be rigidly joined along a direction of gravity to one side of the steel plate 12. These structural members 14 may withstand the loads applied on the steel plate concrete wall, along with the steel plates 12 and the concrete. The structural members 14 may be arranged along a direction of gravity, to withstand axial loads applied on the steel plate concrete wall and withstand lateral loads caused by earthquakes, wind, etc. That is, the structural members 14 may be coupled to one side of each steel plate 12 along a longitudinal direction of the steel plate concrete wall. Together with the concrete in the steel plate structure 10 and the steel plates 12, the structural members 14 may withstand loads in the axial direction, as well as shear forces in the lateral direction caused by earthquakes, etc., when the steel plate concrete wall is rigidly joined to the foundation.
Together with the studs 18, which will be described later in further detail, the structural members 14 may also contribute to integrating the steel plates 12 with the concrete. Thus, as the structural members 14 may serve as structural elements along with the steel plates 12 and the concrete, the overall thickness of the steel plate concrete wall can be reduced, to be useful in forming a wall in a large-scale structure, and the thickness of the steel plates 12 can be reduced, to reduce the amount of thermal deformations during welding operations. Furthermore, the structural members 14 can prevent deformations in the steel plate structures 10 due to eccentricity or twisting while transporting the steel plate structures 10 after manufacture at the factory, and can also prevent deformations in the steel plate structures 10 caused by the lateral pressures of unhardened concrete while casting the concrete in the steel plate structures 10.
The structural members 14 may be rigidly joined to the steel plates 12, so as to move as an integrated body with the steel plates 12. Methods of rigidly joining the steel plates 12 and the structural members 14 can include joining the steel plates 12 with the structural members 14 by using high-tension bolts or rivets, and welding the structural members 14 to the steel plates 12, so that the structural members 14 may move as an integrated body with the steel plates 12.
Various types of structural material, such as L-beams, H-beams, I-beams, T-beams, etc., can be used for the structural members 14. This particular embodiment presents an example in which H-beams are used for the structural members 14, with the flanges of the H-beams rigidly joined to one side of each steel plate 12.
It is possible to rigidly join the structural members 14 to just one of the two steel plates 12 or to both of the steel plates 12. A suitable number of structural members 14 can be coupled to one side of a steel plate 12 in accordance with the load applied on the steel plate concrete wall. When rigidly joining the structural members 14 to both of the steel plates 12, the structural members 14 can be arranged facing each other, as illustrated in Figure 8. In such cases where the structural members 14 are arranged on the steel plates 12 to face each other, struts can be coupled to opposing pairs of structural members 14. With the structural members 14 rigidly joined to the steel plates 12 along the direction of gravity, the combined effect of the steel plates 12, concrete, and structural members 14 can increase load-bearing strength, so that a thick wall, for a skyscraper, nuclear power plant, etc., can be formed without increasing the thickness of the steel plates 12. Thus, since the load-bearing strength can be increased without increasing the thickness of the steel plates 12, the minimized thicknesses for the steel plates 12 allow easy manufacture and installation of the steel plate structure 10, and in cases where the steel plate structure 10 is modularized and assembled on site, the size of the modules may be increased.
The other components of the present embodiment are substantially the same as those described above, and thus will not be described again.
Figure 10 illustrates the construction of a steel plate concrete wall according to the third disclosed embodiment of the present invention. Illustrated in Figure 10 are steel plate structures 10, concrete 30, and a concrete feeder 28.
A steel plate concrete wall according to the present embodiment may be a wall formed by coupling together a multiple number of steel plate structures 10, each of which is made as a unit module, and then casting concrete therein. The steel plate structure 10 may include a pair of steel plates that are separated from each other with one side of one steel plate facing one side of the other steel plate such that a space is defined in-between, struts maintaining a distance between the pair of steel plates, and perforated pipes positioned in the space that extend from one end of the space to the other end of the space and have a multiple number of holes formed therein. The perforated pipes of adjacent steel plate structures 10 maybe interconnected.
A steel plate structure 10 may form a unit module, where many unit modules can be assembled to form a wall of a particular size. That is, the steel plate structures 10 can be manufactured as unit modules at a factory and joined together on site to form walls. It is also possible to form steel plate concrete walls by assembling many unit modules of steel plate structures 10 to fabricate one large module, hoisting and installing the large module in the final position, and then casting concrete therein. After manufacturing a required number of the steel plate structures 10, which form unit modules, the unit modules of steel plate structures 10 may be transported to the construction site and assembled to form one large module. Then, the concrete 30 may be cast inside, using a concrete feeder 28, to form a steel plate concrete wall.
Manufacturing the steel plate structures 10 at a factory can provide higher quality, due to the relatively easier quality management, and can shorten the construction time, due to the minimized amount of work required on site.
While the present invention has been described with reference to particular embodiments, it is to be appreciated that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention, as defined by the appended claims below.
[Industrial Applicability] Vapors created by high levels of heat within a steel plate concrete wall can be effectively displaced, to prevent the steel plate concrete wall from expanding or bursting and to improve durability.
By utilizing structural members, which can support loads together with the steel plates and the concrete, the overall thickness of the steel plate concrete wall can be reduced, allowing for a more efficient use of space.
