Description

Technical Field

[0001] The invention belongs to the technical field of nuclear facility construction, and particularly relates to the layout and connection joints of a steel plate concrete shielding workshop and a reinforced concrete wall. Background Art

[0002] The shielding workshop of a nuclear facility is a cylindrical structure, which is required to have the functions of anti-impact and anti-radiation. Usually, a reinforced concrete structure is adopted, so that the reinforced concrete wall connected to the periphery of the shielding workshop is integrally cast to meet the use requirements of the shielding workshop. However, the cross-sectional size of the shielding workshop with a reinforced concrete structure is relatively large, increasing the floor area of the workshop.

[0003] Compared with the traditional reinforced concrete structure shielding workshop, the shielding workshop with a steel plate concrete structure has a smaller cross-sectional size and higher bearing capacity, and has higher anti-impact and anti-radiation capabilities. However, the shielding workshop with a steel plate concrete structure has the following disadvantages:

[0004] 1. There is a conflict in the spatial position of the crane track beam extending from the reinforced concrete wall arranged around the outside of the circular arc steel plate concrete shielding workshop. The distance between the circular arc shielding workshop and the reinforced concrete wall cannot meet the requirements of the crane span and travel range. Usually, it is necessary to adjust the spatial layout of the circular arc shielding workshop and the reinforced concrete wall arranged around to meet the requirements of the crane span and travel range, but this will increase the floor area of the entire workshop and even affect the layout of the entire nuclear facility plant area.

[0005] 2. Since the shielding workshop with a steel plate concrete structure and the reinforced concrete wall arranged around are of different structures and cannot be integrally cast, the circular arc steel plate concrete shielding workshop is connected to the surrounding reinforced concrete wall at a small angle approximately tangent. The horizontal steel bars of the reinforced concrete wall cannot extend into the inside of the arc steel plate concrete shielding workshop for anchoring, and a reliable connection between the reinforced concrete wall and the steel plate concrete wall cannot be achieved. Summary of the Invention

[0006] Aiming at the defects or deficiencies in the prior art, the invention provides the layout and connection joints of a steel plate concrete shielding workshop and a reinforced concrete wall, which can not only meet the requirements of the crane span and travel range, but also realize the reliable connection between the reinforced concrete wall and the steel plate concrete wall.

[0007] To achieve the above object, the invention adopts the following technical solutions:

[0008] Embodiments of the present invention provide an arrangement and connection node of a steel plate concrete shielding workshop and a reinforced concrete wall, including an outer steel wall panel arranged on the outside of the steel plate concrete shielding workshop. The steel plate concrete shielding workshop is arc-shaped, and the reinforced concrete wall is connected to the steel plate concrete shielding workshop along the normal direction and the approximate tangent direction of the arc-shaped steel plate concrete shielding workshop.

[0009] A locally concave area and a locally protruding area are provided on the outer steel wall panel. The outer side of the locally concave area, the outer side of the locally protruding area, and the outer side of the reinforced concrete wall connected along the approximate tangent direction of the arc-shaped steel plate concrete shielding workshop are connected in sequence and are coplanar.

[0010] Further, the locally protruding area includes a first vertically protruding panel and a second vertically protruding panel. The first vertically protruding panel extends out of the outer steel wall panel along the approximate tangent direction of the arc-shaped outer steel wall panel, and the second vertically protruding panel is arranged at one end of the first vertically protruding panel extending out of the outer steel wall panel.

[0011] The locally protruding area is correspondingly arranged with the surrounding reinforced concrete wall. A plurality of holes are provided on the second vertically protruding panel, and the plurality of holes correspond to the horizontal steel bars in the reinforced concrete wall.

[0012] Further, a locally concave area is provided on the outer steel wall panel. The locally concave area includes a first vertically concave panel and a second vertically concave panel. The first vertically concave panel extends into the interior of the arc-shaped steel plate concrete workshop along the approximate tangent direction of the arc-shaped outer steel wall panel, and the second vertically concave panel is arranged at one end of the first vertically concave panel extending into the outer steel wall panel.

[0013] The ratio of the distance between the first vertically concave panel and the outer steel wall panel to the radius of the outer steel wall panel does not exceed 1%.

[0014] Further, the outer steel wall panel is connected to the inner steel wall panel through tension bars, and concrete is poured between the outer steel wall panel and the inner steel wall panel.

[0015] Further, one end of the second vertically concave panel is connected to the outer steel wall panel, and the other end is connected to the first vertically concave panel. Horizontal concave panels are provided at both the upper and lower ends of the first vertically concave panel and the second vertically concave panel.

[0016] Further, one end of the second vertically protruding panel is connected to the outer steel wall panel, and the other end is connected to the first vertically protruding panel.

[0017] Further, mechanical connection sleeves are provided at the holes of the second vertically protruding panel.

[0018] Furthermore, a channel-shaped support plate is also provided on the outer steel wall panel, and the channel-shaped support plate protrudes outside the outer steel wall panel along the normal direction of the arc-shaped outer steel wall panel.

[0019] Furthermore, the channel-shaped support plate corresponds to the surrounding reinforced concrete wall, and a plurality of holes are formed in the channel-shaped support plate, and the holes correspond to the positions of the horizontal steel bars of the reinforced concrete wall.

[0020] Furthermore, mechanical connection sleeves are provided at the holes of the channel-shaped support plate.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. By providing a locally concave area on the outer steel wall panel of the present invention and extending it into the arc-shaped steel plate concrete shielding plant along the approximate tangent direction of the arc, irregular excision inside the arc-shaped shielding plant is realized, and a concave space is formed within the cross-sectional thickness range of the arc-shaped steel plate concrete shielding plant;

[0023] By providing a locally protruding area on the outer steel wall panel and extending it outside the outer steel wall panel along the approximate tangent direction of the arc, a protruding area corresponding to the reinforced concrete wall connected along the approximate tangent direction of the arc-shaped steel plate concrete shielding plant is formed;

[0024] By connecting and coplanarly arranging the outer side of the locally concave area, the outer side of the locally protruding area, and the outer side of the reinforced concrete wall connected along the approximate tangent direction of the arc-shaped steel plate concrete shielding plant, on the basis of not adjusting the spatial layout of the arc-shaped shielding plant and the surrounding connected reinforced concrete walls, the problem of spatial position conflict of the crane track beam extending from the outside of the arc-shaped steel plate concrete shielding plant and the surrounding connected reinforced concrete walls is avoided, meeting the requirements of the span and travel range of the crane.

[0025] 2. By providing a locally protruding area on the outer steel wall panel of the present invention, and the locally protruding area corresponds to the surrounding reinforced concrete wall, and a plurality of holes are formed in the second vertically protruding panel, and the plurality of holes correspond to the horizontal steel bars in the reinforced concrete wall, so that the horizontal steel bars of the reinforced concrete wall can directly extend into the arc-shaped steel plate concrete shielding plant through the holes, meeting the requirements of the anchorage length, thereby realizing the reliable connection between the reinforced concrete wall and the steel plate concrete wall.

[0031] The present invention will be further described below in conjunction with the drawings and embodiments.

[0032] A typical implementation manner of the present invention is as shown in Figure 1 and Figure 2 The layout and connection nodes of the steel - plate concrete shielding workshop and the reinforced - concrete wall include an outer steel wall panel 1 and an inner steel wall panel 2. The outer steel wall panel 1 and the inner steel wall panel 2 are connected by a plurality of tie - bars 3. Concrete is poured between the outer steel wall panel 1 and the inner steel wall panel 2. By the combined action of the inner and outer steel wall panels and the concrete, the overall strength of the steel - plate concrete wall is ensured.

[0033] A local concave area 4 is provided on the outer steel wall panel 1. The local concave area includes a first vertical concave panel 41 and a second vertical concave panel 42. The first vertical concave panel 41 extends into the steel - plate concrete shielding workshop 5 along an approximately tangential direction of the circular - arc - shaped outer steel wall panel 1. The second vertical concave panel 42 is arranged at one end of the first vertical concave panel 41 extending into the outer steel wall panel 1. One end of the second vertical concave panel 42 is connected to the outer steel wall panel 1, and the other end is connected to the first vertical concave panel 41. Horizontal concave panels 43 are arranged at the upper and lower ends of the first vertical concave panel 41 and the second vertical concave panel 42. By providing the horizontal concave panels 43, the upper and lower ends of the local concave area 4 are closed, thereby ensuring the integrity of the outer steel wall panel 1.

[0034] The ratio of the distance between the first vertical concave panel 41 and the outer steel wall panel 1 to the radius of the outer steel wall panel does not exceed 1%, so that the first vertical concave panel 41 extends into the interior of the steel - plate - shaped earth shielding workshop 5 along an approximately tangential direction of the circular - arc - shaped outer steel wall panel 1.

[0035] By setting a locally concave area 4 on the outer steel wall panel 1, a locally concave space is formed within the cross-sectional thickness range of the circular arc steel plate concrete shielding plant 5, realizing the irregular excision inside the circular arc shielding plant 5.

[0036] A locally protruding area 6 is also set on the outer steel wall panel 1. The locally protruding area 6 includes a first vertical protruding panel 61 and a second vertical protruding panel 62. The first vertical protruding panel 61 extends out of the outer steel wall panel 1 along the tangent direction of the circular arc outer steel wall panel 1. The second vertical protruding panel 62 is arranged at one end of the first vertical protruding panel 61 that extends out of the outer steel wall panel 1. One end of the second vertical protruding panel 62 is connected to the outer steel wall panel 1, and the other end is connected to the first vertical protruding panel 61.

[0037] The locally protruding area 6 is arranged corresponding to the surrounding reinforced concrete wall 7. A plurality of holes are formed in the second vertical protruding panel 62, and the plurality of holes correspond to the horizontal steel bars 8 inside the reinforced concrete wall 7. The horizontal steel bars 8 of the reinforced concrete wall 7 can directly extend into the circular arc steel plate concrete shielding plant 5 through the holes to meet the requirement of the anchorage length, thereby realizing the reliable connection between the reinforced concrete wall 7 and the steel plate concrete wall.

[0038] A mechanical connection sleeve 9 is arranged at the joint of the horizontal steel bar 8 of the reinforced concrete wall 7 and the hole of the second vertical protruding panel 62.

[0039] By setting the locally protruding area 6, a locally protruding space is formed outside the circular arc steel plate concrete shielding plant 5. The locally protruding space corresponds to the surrounding reinforced concrete wall 7, avoiding the direct connection of the reinforced concrete wall 7 to the circular arc steel plate concrete shielding plant 5 at a small angle approximately tangent.

[0040] If the locally protruding area 6 is not set outside the circular arc steel plate concrete shielding plant 5, the reinforced concrete wall 7 is directly connected to the circular arc steel plate concrete shielding plant 5 at a small angle approximately tangent. The thickness of the reinforced concrete wall 7 in the connection area is a variable cross-section that gradually changes from 0 along the arc length direction to the thickness of the reinforced concrete wall 7, making it impossible to guarantee the bearing capacity of the connection area. At the same time, with the approximate tangent small angle connection, the horizontal steel bars 8 of the reinforced concrete wall 7 cannot extend into the circular arc steel plate concrete shielding plant 5 for anchorage, and the reliable connection between the reinforced concrete wall 7 and the steel plate concrete wall cannot be realized.

[0041] A channel-shaped support plate 12 is also provided on the outer steel wall panel 1. The channel-shaped support plate 12 protrudes outside the outer steel wall panel 1 along the normal direction of the arc-shaped outer steel wall panel 1. The channel-shaped support plate 12 corresponds to the surrounding reinforced concrete wall 7. A plurality of holes are formed in the channel-shaped support plate 12, and the positions of the holes correspond to the horizontal steel bars 8 of the reinforced concrete wall 7. The horizontal steel bars 8 of the reinforced concrete wall 7 can pass through the holes in the channel-shaped support plate 12 and directly extend into the interior of the arc-shaped steel plate concrete shielding workshop 5 to meet the requirements of the anchorage length, thereby realizing the reliable connection between the reinforced concrete wall 7 and the steel plate concrete wall.

[0042] A mechanical connection sleeve 9 is provided at the connection between the horizontal steel bar 8 of the reinforced concrete wall 7 and the hole of the channel-shaped support plate 12.

[0043] As Figure 3 shown, the intersection of the horizontal steel bar 8 of the reinforced concrete wall 7 and the steel wall panel of the steel plate concrete shielding workshop 5 is divided into inner and outer sections. The horizontal steel bar 8 of the reinforced concrete wall located inside the steel plate concrete shielding workshop 5 is fabricated and installed simultaneously with the mechanical sleeve 9 and the steel wall panel. The horizontal steel bar 8 of the reinforced concrete wall located outside the steel plate concrete shielding workshop is connected by a mechanical sleeve after the installation of the steel wall panel is completed. Thus, during the fabrication stage of the steel plate concrete shielding workshop 5, no steel bars protrude outside the steel wall panel, reducing the overall external dimension, facilitating the hoisting, flipping, alignment and transportation of the steel wall panel, and ensuring the safety and convenience of construction.

[0044] The crane girders 11 are arranged in a straight line outside the local concave area 4, the local protruding area 6 and the reinforced concrete wall 7 connected along the approximate tangent direction of the arc. The first vertical concave panel 41, the first vertical protruding panel 61 and the outer side surface of the reinforced concrete wall 7 connected along the approximate tangent direction of the arc are connected and coplanar, avoiding increasing the overall plane dimension of the entire workshop to meet the requirements of the crane's span and travel range, and meeting the functional layout requirements without increasing the plane dimension of the workshop, thereby reducing the floor area of the workshop.

[0045] As Figure 4 shown, a plurality of steel corbels 10 are also provided on the outer steel wall panel 1. The plurality of steel corbels 10 are arranged side by side, and some of the steel corbels 10 are located below the local concave area 4. The crane girders 11 are supported above the plurality of steel corbels 10.

[0046] The steel corbels 10 are directly connected to the inner and outer steel wall panels of the steel plate concrete shielding workshop 5 and form an integral structural member with the arc-shaped steel plate concrete shielding workshop 5 to jointly bear the load, increasing the overall stiffness of the steel corbels 10, improving the load-bearing capacity of the steel corbels 10, reducing the deformation of the steel corbels 10, and at the same time reducing the fabrication and installation difficulty.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
