Steel plate concrete modular construction, it is steel module that will be prefabricated in the factory in the field weld splicing good, pours concrete again, this construction method is currently often used in the construction of nuclear power plant. Steel plate concrete structure mainly is by two sides stress steel plate and internal core concrete composition, will carry out the connection between two side steel plate through the tensile type steel, like this guarantees the integrity of steel plate concrete wall.

[0003] Different from general reinforced concrete, the core concrete between two steel plates is not configured with horizontal and vertical stress reinforcement, nor with conventional tie and stirrup shear reinforcement. Compared with the traditional reinforced concrete structure, steel plate concrete structure has obvious advantages in construction schedule. The shortening of construction schedule mainly reflects in the binding of reinforcement before pouring and the removal of formwork after pouring and curing. According to existing data, for steel plate concrete structure and reinforced concrete structure of the same size, the former construction speed is twice that of the latter.

[0004] The existing wall corner only has 90 DEG connecting structure, but in actual construction engineering, because wall body cannot only have 90 DEG corner connection, there will be special situation of non 90 DEG corner connection. For steel plate concrete module wall body in non 90 DEG corner connection, there is no explicit structure, which limits the application and popularization of steel plate concrete structure to some extent. UTILITY MODEL CONTENTS

[0005] In view of the problems existing in the prior art, the utility model provides a steel plate concrete module wall body corner connecting structure to improve the existing steel plate concrete module wall body corner only has 90 DEG connecting structure, and there is no explicit connecting structure for non 90 DEG corner connection, and the strength cannot be guaranteed.

[0006] To achieve the above and other related objectives, this utility model provides a corner connection structure for a steel plate concrete modular wall, comprising two sets of steel plates, reinforcing ribs, a tie member, and a reinforcing member; each set of steel plates includes a first steel plate and a second steel plate arranged opposite to each other, the two sets of steel plates being fixed together, and the angle between the two second steel plates toward the first steel plate being less than 180°; the reinforcing ribs are fixedly disposed on opposite sides of the first steel plate and the second steel plate; both ends of the tie member are fixed to the reinforcing ribs on the first steel plate and the second steel plate, respectively; the reinforcing member is disposed in the connection area of ​​the two sets of steel plates, at least one end of the reinforcing member being connected to the corner of the two first steel plates, and the other end being connected to the corner of the two second steel plates or connected to the second steel plate.

[0007] In one embodiment of this utility model, a stud is included and fixedly disposed on one side opposite to the steel plate, and a stud head is provided on the side of the stud away from the fixed end.

[0008] In one embodiment of the present invention, the reinforcing member includes two members, one end of which is connected to the corner of the first steel plate, and the other end extends along the plane of the first steel plate to the second steel plate of another group.

[0009] In one embodiment of this utility model, the rotation angle of the two first steel plates is α, where 90°≤α≤120°.

[0010] In one embodiment of the present invention, the reinforcing member includes a first member and a second member. The two ends of the first member are respectively fixed at the corner of the first steel plate and the corner of the second steel plate; the two ends of the second member are respectively fixed at the opposite sides of the first steel plate and the second steel plate in the same group.

[0011] In one embodiment of the present invention, the first component is a tie plate, which longitudinally penetrates the corner of the two first steel plates.

[0012] In one embodiment of this utility model, the tie plate is provided with through holes.

[0013] In one embodiment of this utility model, the second component is a tie plate, and the tie plate is provided with through holes.

[0014] In one embodiment of this utility model, the second component is a tie bar, which is perpendicular to the first steel plate.

[0016] In combination with existing technologies, the beneficial effects of this utility model are as follows:

[0017] Existing wall connection structures only have 90° angle connections, lacking a clear connection structure for non-90° corner connections. This leads to instability and compromised strength in non-90° corner connections. In this application, the first and second steel plates are relatively fixed together by reinforcing ribs and tie rods, ensuring stability in the non-plate connection area and allowing concrete to be poured between them. Furthermore, the first and second steel plates are located in the outermost layer, which is most advantageous for bending, resulting in higher bending load-bearing capacity.

[0018] In actual use, the corners of the two first steel plates tend to open or close due to stress. By setting reinforcing members in the connection area of ​​the steel plate group, one end of the reinforcing member is fixed at the corner of the two first steel plates, and the other end is connected to the second steel plate or the corner of the second steel plate, the strength of the corners of the two first steel plates is effectively improved, the problem of cracking or deformation of the corners of the first steel plates is alleviated, and the stability of the corners of the wall is effectively improved.

[0029] Steel plate concrete (SPC) structures are widely used in engineering projects, especially in the construction of nuclear power plants, due to their advantages such as high construction efficiency and good load-bearing performance. However, existing SPC modular walls can only be used at 90° corners. For corners greater than 90°, the SPC module cavity is prone to tensile cracking or extrusion deformation at the corner, making it unusable. However, in actual construction projects, especially in the construction of nuclear power plants, corners greater than 90° are quite common. In view of this, this application provides a corner connection structure for SPC modular walls to improve the strength of the wall corner connection, especially the stability of the wall corner connection greater than 90°.

[0030] Please see Figures 1 to 4This utility model provides a corner connection structure for a steel plate concrete modular wall, including two sets of steel plate groups 100, reinforcing ribs 200, tension members 300, and reinforcing components 400. Each set of steel plate groups 100 includes a first steel plate 110 and a second steel plate 120 arranged opposite each other. The two first steel plates 110 and the two second steel plates 120 are fixed together to fix the two sets of steel plate groups 100. The fixed connection between the two first steel plates 110 includes, but is not limited to, welding connection and integral molding connection. The angle between the two second steel plates 120 and the first steel plate 110 is less than 180°, that is, the first steel plate 110 is on the inner side of the connection structure, and the second steel plate 120 is on the outer side of the connection structure. The width of the first steel plate 110 at the corner connection is less than the width of the second steel plate 120 at the corner connection. Reinforcing ribs 200 are fixedly disposed on opposite sides of the first steel plate 110 and the second steel plate 120. By fixing reinforcing ribs 200 to the first steel plate 110 and the second steel plate 120 respectively, it is convenient for the tension member 300 to be fixed to the first steel plate 110 and the second steel plate 120 respectively. Both ends of the tension member 300 are fixed to the reinforcing ribs 200 on the first steel plate 110 and the second steel plate 120 respectively. The tension member 300 fixes the first steel plate 110 and the second steel plate 120 relatively, preventing relative movement between the first steel plate 110 and the second steel plate 120, and facilitating the pouring of concrete in the area between the first steel plate 110 and the second steel plate 120. Reinforcing members 400 are disposed in the connection area of ​​the two sets of steel plates. At least one end of the reinforcing member 400 is connected to the corners of the two first steel plates 110, and the other end is connected to the corners of the two second steel plates 120 or connected to the second steel plate 120. By fixing reinforcing members 400 at the corners of the two first steel plates 110, the strength at the corners of the first steel plates 110 can be improved. By supporting the corners of the first steel plates 110 with the second steel plate 120 or the corners of the second steel plate 120, the stability at the corners of the first steel plates 110 can be effectively improved when the steel plate concrete wall is subjected to a force parallel to the wall, thus mitigating the situation of tensile cracking or extrusion deformation at the corners of the first steel plate 110, and promoting the application and promotion of steel plate concrete modular walls.

[0031] In one embodiment, the reinforcing rib 200 is a structure that penetrates the wall along the height direction, such as angle steel, channel steel, or other structural steel, to improve the fixing strength of the reinforcing rib 200 to the first steel plate 110 and the second steel plate 120. The fixing methods of the reinforcing rib 200 to the first steel plate 110 and the second steel plate 120 include, but are not limited to, welding connections, with welding connections being preferred, as this facilitates construction and effectively ensures the fixing strength of the reinforcing rib 200 to the first steel plate 110 and the second steel plate 120.

[0032] Please see Figure 1 and Figure 2In one embodiment, the first steel plate 110 and the second steel plate 120 are arranged in parallel to ensure the stability of the wall under stress and reduce stress concentration. Of course, as some optional solutions, the first steel plate 110 and the second steel plate 120 are not arranged in parallel to meet the needs of special situations.

[0033] Please see Figure 1 and Figure 2 In one embodiment, the tension member 300 is arranged in a direction perpendicular to the first steel plate 110. The tension member 300 ensures the connection strength between the first steel plate 110 and the second steel plate 120, preventing the first steel plate 110 and the second steel plate 120 from separating due to concrete compression during pouring. The connection between the tension member 300 and the reinforcing rib 200 includes, but is not limited to, a welded connection, with welding being preferred due to its ease of construction and high connection strength.

[0034] In one embodiment, the tie structures are arranged in an array along the height of the wall to ensure stability at all points along the wall's height. Of course, as optional solutions, the tie structures can be arranged at unequal intervals according to actual needs, such as having more tie structures on the upper side of the wall or more tie structures on the lower side of the wall.

[0035] Please see Figure 1 and Figure 2 In one embodiment, a stud 500 is included, fixedly disposed on the opposite side of the steel plate, with a stud head provided on the side of the stud 500 away from the fixed end. By respectively providing studs 500 on the opposite sides of the first steel plate 110 and the second steel plate 120, the concrete is respectively connected to the first steel plate 110 and the second steel plate 120, ensuring the integrity of the steel plate concrete wall and preventing the concrete from separating from the first steel plate 110 or the second steel plate 120. The connection method between the stud 500 and the first steel plate 110 includes, but is not limited to, welding connection, and the connection method between the stud 500 and the second steel plate 120 includes, but is not limited to, welding connection.

[0036] In one embodiment, the studs 500 are arranged at equal intervals in the height and length directions of the wall to ensure the connection stability between the concrete and the first steel plate 110 and the second steel plate 120, and to ensure the integrity of the steel plate concrete wall.

[0037] Of course, as an alternative, the 500 studs can also be arranged at unequal intervals along the height or length of the wall, depending on the actual needs of the construction.

[0038] Please see Figure 2In one embodiment, the reinforcing member 400 includes two members. One end of the reinforcing member 400 is connected to the corner of the first steel plate 110, and the other end extends along the plane of the first steel plate 110 to the second steel plate 120 of another group. The two reinforcing members 400 provide support for the two first steel plates 110 respectively, which improves the tensile and compressive strength at the corner of the first steel plate 110 and improves the problem that the corner of the first steel plate 110 is prone to cracking or extrusion deformation.

[0039] Please see Figure 2 In one embodiment, the rotation angle of the two first steel plates 110 is α, 90°≤α≤120°. The reinforcing member 400 is connected to the rotation angle of the first steel plate 110 and the second steel plate 120 respectively by welding. When the rotation angle of the first steel plate 110 is less than or equal to 120°, the angle between the reinforcing member 400 and the second steel plate 120 is greater than or equal to 60°, which facilitates the welding operation between the reinforcing member 400 and the second steel plate 120 and improves the connection stability and operation convenience.

[0040] In one embodiment, the reinforcing member 400 is a tie plate 421, which provides stable support for the corner of the first steel plate 110. The tie plate 421 is provided with a through hole 4211 to allow concrete to pass through.

[0041] Please see Figure 4 In one embodiment, the reinforcing member 400 includes a first member 410 and a second member 420. The two ends of the first member 410 are respectively fixed to the corners of the first steel plate 110 and the second steel plate 120. The first member 410 connects the corners of the first steel plate 110 and the second steel plate 120, preventing relative movement between the two corners and thus improving the stability of the wall corners. The two ends of the second member 420 are respectively fixed to the opposite sides of the first steel plate 110 and the second steel plate 120 in the same group. The second member 420 is perpendicular to the first steel plate 110. By reinforcing and fixing the first steel plate 110 and the second steel plate 120 in the same group through the second member 420, the opposite steel plate can provide support when the first steel plate 110 or the second steel plate 120 is under stress, improving the problem of tensile cracking or extrusion deformation at the corners. For example, when the first steel plate 110 is subjected to an external force that causes a tendency for the first steel plate 110 to crack at the corner, the force decomposition determines that the first steel plate 110 is subjected to a force perpendicular to the first steel plate 110 and toward the second steel plate 120. The length direction of the reinforcing member 400 is consistent with the direction of this force, thereby improving the support for the first steel plate 110.

[0042] Please see Figure 4In one embodiment, the first component 410 is a tie plate 421. The tie plate 421 extends longitudinally through the corners of the two first steel plates 110. Both ends of the tie plate 421 are connected to the corners of the first steel plate 110 and the second steel plate 120, respectively. The connection method includes, but is not limited to, welding. The angle between the tie plate 421 and the first steel plate 110 is greater than or equal to 90°, and the angle between the tie plate 421 and the second steel plate 120 is greater than or equal to 45°. This facilitates the operation and processing of fixing the tie plate 421 to the corners of the first steel plate 110 and the second steel plate 120. The first steel plate 110 has good tensile strength, which can effectively ensure the connection strength between the corners of the first steel plate 110 and the second steel plate 120, prevent relative displacement between the corners of the first steel plate 110 and the second steel plate 120, and ensure the stability of the wall corners.

[0043] Please see Figure 3 In one embodiment, the tie plate 421 is provided with a through hole 4211, through which concrete flows, ensuring the integrity of the concrete and improving the integrity of the wall.

[0044] In one embodiment, the through hole 4211 can be a regular-shaped through hole 4211 such as a rectangular hole, a circular hole, or a diamond-shaped hole, or it can be a through hole 4211 with a combination of multiple shapes, or it can be a through hole 4211 with other irregular shapes, depending on actual needs.

[0045] In one embodiment, the through holes 4211 are arranged at equal intervals along the height of the wall to improve the uniformity of concrete flow. Of course, as some optional solutions, the through holes 4211 are arranged at unequal intervals along the height of the wall, depending on the actual construction needs.

[0046] Please see Figure 2 In one embodiment, the second component 420 is a tie plate 421, which has through holes 4211 to effectively ensure the connection strength of the first steel plate 110 and the second steel plate 120 in the connection area.

[0047] Please see Figure 4 In one embodiment, the second component 420 is a tie bar 422, which is perpendicular to the first steel plate 110. The tie bar 422 has sufficient tensile strength and can be directly fixed to the first steel plate 110 and the second steel plate 120. The construction is convenient and simple, and the connection stability is good.

[0048] In one embodiment, the tie bars 422 are arranged in an array along the height direction of the wall and along the width direction of the wall to ensure the connection stability and stress uniformity of the first steel plate 110 and the second steel plate 120 in the connection area.

[0049] Of course, as some optional solutions, the 422 tie bars can be arranged at unequal intervals along the width or height of the wall, depending on the construction needs.

[0050] The steel plate concrete modular wall corner connection structure of this application can effectively ensure the stability of the 100° connection area between two sets of steel plates, and is particularly suitable for improving the stability of non-90° corner connection areas and mitigating tensile cracking or compression deformation in corner connection areas. Simultaneously, the steel plate concrete structure facilitates construction and places the steel plates in the most advantageous outer layer for bending, resulting in higher bending bearing capacity. Under in-plane shear, the steel plates have a much stronger shear capacity than concrete and reinforcing steel, thus allowing for a more relaxed shear-compression ratio limit and saving materials. Concrete cracks are not exposed, improving durability, and the steel plates constrain the structure, resulting in greater stiffness. When the ultimate failure mode of the structure is controlled by the yielding of the tension-side steel plates, it exhibits excellent ductility, and the constraint of the outer steel plates on the inner concrete can largely avoid the insufficient ductility caused by concrete brittleness. As an isotropic material, the steel plates have high stress efficiency in components with complex principal tensile stress directions. The steel-concrete composite structure exhibits strong integrity and toughness, particularly with the back steel plate preventing concrete collapse, significantly enhancing its resistance to explosions and impacts. Furthermore, the steel-concrete composite structure boasts excellent sealing performance, facilitating modular construction and saving construction time. Therefore, this invention effectively overcomes some practical problems in existing technologies, thus possessing high utilization value and practical significance.

[0051] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
