Technical Field
[0001] The present application relates to the technical field of steel hanging box connection, and in particular to a connection structure between a steel-concrete composite hanging box wall panel and a bottom panel. Background Art
[0002] The steel box cofferdam is a water-blocking structure used for cap construction. It forms a water-free and dry space for cap construction through the wall and bottom plates of the box cofferdam, which is convenient for cap pouring.
[0003] In order to ensure the quality and safety of construction, conventional steel hanging boxes first install the bottom plate, which is fixed on the top surface of the corbel of the outer wall of the casing. The casing passes through the bottom plate, and then the bottom plate is used to wrap the wall plate. The size of the bottom plate needs to be increased, and the side beams are prefabricated on the bottom plate for the wall plate installation and water sealing. When the wall plate is removed after the construction is completed, it is affected by the connection structure and water sealing treatment, and the bottom end is easily damaged, which is inconvenient to remove. In addition, the bottom plate is exposed to a large extent and needs special treatment. The construction safety risk is high, the operation is difficult, and the bottom of the foundation is easily damaged. Summary of the invention
[0004] In order to improve the convenience of disassembly and assembly between the wall panel and the bottom plate, the present application provides a connection structure between the steel-concrete composite hanging box wall panel and the bottom plate.
[0005] The present application provides a connection structure between a steel-concrete composite hanging box wall panel and a bottom panel, which adopts the following technical solution:
[0006] A connection structure between a steel-concrete composite hanging box wall panel and a bottom plate comprises a bottom plate, the bottom plate side walls are pre-embedded with connecting pieces, the bottom plate side walls are provided with supporting corbels, the supporting corbels are fixed to the bottom plate via the connecting pieces, the top surfaces of the supporting corbels are fixed with wall panels, and the wall panels surround the bottom plate.
[0007] By adopting the above technical solution, by adding a shelf corbel to connect the bottom plate and the wall panel, the wall panel wraps the bottom plate on the inside. Compared with the prior art, the wall panel is installed on the bottom plate. The present application can make the size of the bottom plate consistent with the bottom surface size of the pedestal, thereby reducing the need to specially deal with the extra-wide part of the bottom plate after the steel hanging box is removed in the later stage, improving the quality of the pedestal and reducing the risk of safe operation. At the same time, the shelf corbel is fixedly connected to the bottom plate by a connecting piece, which is more convenient when removed in the later stage, thereby improving the convenience of disassembly and assembly between the wall panel and the bottom plate.
[0008] Preferably, a sealing layer is provided between the supporting corbel and the bottom plate, one side of the sealing layer is pressed against the side wall of the supporting corbel, and the other side of the sealing layer is pressed against the side wall of the bottom plate, and the supporting corbel, the sealing layer and the bottom plate are fixed by the connecting piece.
[0009] By adopting the above technical solution, one side of the sealing layer abuts against the side wall of the supporting corbel, and the other side of the sealing layer abuts against the side wall of the bottom plate. Under the action of the sealing layer, the sealing performance between the supporting corbel and the bottom plate can be improved, and the situation of water seepage through the gap between the supporting corbel and the bottom plate can be reduced.
[0010] Preferably, a sealing layer is poured in the gap between the wall panel and the bottom plate.
[0011] By adopting the above technical solution, under the action of the sealing layer, the gap between the wall panel and the bottom plate can be sealed, thereby reducing the situation of water seepage through the gap between the wall panel and the bottom plate, so that the space enclosed by the wall panel and the bottom plate is a water-free and dry space, which is convenient for the pouring of the bearing platform.
[0012] Preferably, a limiting block is fixed on the top surface of the supporting corbel, and the side wall of the limiting block abuts against the outer wall of the wall panel.
[0013] By adopting the above technical solution, under the action of the limiting block, the structural stability of the bottom of the wall panel can be increased. The limiting block plays a role of resisting and limiting. When the wall panel is subjected to an outward horizontal force, the limiting block can resist the outward force of the wall panel, so that the wall panel is more stable and the situation of the wall panel shaking and being unstable is reduced.
[0014] Preferably, a first pull rod is connected to one end of the casing close to the wall panel, and the top end of the first pull rod is connected to the bottom of the side wall of the wall panel.
[0015] By adopting the above technical solution, the first pull rod, the wall panel and the bottom plate form a triangle in cross section. The triangle has stability.

[0017] By adopting the above technical solution, the second pull rod, the wall panel and the bottom plate form a triangle in cross section. Under the action of the second pull rod, the second pull rod supports the top of the wall panel. When the wall panel is subjected to a horizontal force, the force received by the top of the wall panel is transmitted to the casing through the second pull rod, and the casing provides a supporting force for the second pull rod, so that the position of the wall panel is more stable and the situation of the wall panel shaking, being unstable and toppling is reduced.
[0018] Preferably, the sealing layer is a rubber cushion layer.
[0019] By adopting the above technical solution, the rubber cushion layer has good elasticity and can maintain the sealing performance between the wall panel and the bottom plate. At the same time, even under the condition of pressure change or temperature fluctuation, the rubber cushion layer can well fill the irregularities of the joint surface, provide a good sealing effect, and reduce the situation of water seepage between the wall panel and the bottom plate.
[0020] Preferably, the limiting block is a right trapezoidal block, the side of the limiting block away from the wall panel is an inclined surface, and the width of the top of the limiting block is smaller than the width of the bottom of the limiting block.
[0021] By adopting the above technical solution, the limiting block is a right trapezoidal block, so that the contact area with the top surface of the supporting bracket can be increased, and then the friction force with the supporting bracket can be increased, further increasing the connection stability between the limiting block and the supporting bracket. The inclined surface of the limiting block forms a triangle with the side wall of the wall panel and the top surface of the supporting bracket, forming a relatively stable structure, which can better provide support force for the wall panel. At the same time, the center of gravity of the limiting block is relatively low, so that the limiting block is not easily overturned after being subjected to a horizontal force.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. By adding supporting brackets to connect the bottom plate and the wall panel, and the wall panel wraps the bottom plate inside. Compared with the prior art where the wall panel is installed on the bottom plate, the present application can make the size of the bottom plate consistent with the size of the bottom surface of the bearing platform, reduce the need to specially process the over-wide part of the bottom plate after the later removal of the steel lifting box, improve the quality of the bearing platform, reduce the safety operation risk, and at the same time, the supporting bracket and the bottom plate are fixedly connected by connecting parts, which is more convenient for later removal, thus improving the disassembly and assembly convenience between the wall panel and the bottom plate.
[0024] 2. One side of the sealing layer abuts against the side wall of the supporting bracket, and the other side of the sealing layer abuts against the side wall of the bottom plate. Under the action of the sealing layer, the sealing performance between the supporting bracket and the bottom plate can be improved, and the situation of water seepage from the gap between the supporting bracket and the bottom plate can be reduced.

[0028] The following is combined with Figure 1-2 This application is described in further detail.
[0029] The embodiment of the present application discloses a connection structure between a steel-concrete composite hanging box wall panel and a bottom panel.
[0030] Reference Figure 1 and Figure 2 A connection structure between a steel-concrete combined hanging box wall panel and a bottom plate includes a bottom plate 1. In the embodiment of the present application, the bottom plate 1 is a rectangular plate, and a connecting piece is pre-embedded in the side wall of the bottom plate 1. In the embodiment of the present application, the connecting piece is a conical bolt 11, and there are multiple conical bolts 11, and the multiple conical bolts 11 are distributed around the bottom plate 1. The side wall of the bottom plate 1 is provided with a shelf corbel 2, and there are multiple shelf corbels 2, and the multiple shelf corbels 2 are distributed around the bottom plate 1. The shelf corbels 2 and the bottom plate 1 are fixed by conical bolts 11. A wall panel 3 is provided on the top surface of the shelf corbel 2, and the wall panel 3 and the shelf corbel 2 are fixed by pre-embedded anchor cones 21. The wall panel 3 surrounds the bottom plate 1.
[0031] By adding a shelf corbel 2 to connect the base plate 1 and the wall panel 3, the wall panel 3 wraps the base plate 1 on the inside. Compared with the prior art, in which the wall panel is installed on the base plate, the present application can make the size of the base plate 1 consistent with the bottom surface size of the pedestal, thereby reducing the need to specially deal with the extra-wide part of the base plate 1 after the steel hanging box is removed in the later stage, improving the quality of the pedestal and reducing the risk of safe operation. At the same time, the shelf corbel 2 is fixedly connected to the base plate 1 by a conical bolt 11, which is more convenient when removed in the later stage, thereby improving the convenience of disassembly and assembly between the wall panel 3 and the base plate 1.
[0032] A sealing layer 4 is provided between the side wall of the shelf corbel 2 and the bottom plate 1, and the shelf corbel 2, the sealing layer 4 and the bottom plate 1 are fixed by means of a conical bolt 11. In the embodiment of the present application, the sealing layer 4 is a rubber pad, and one side of the sealing layer 4 is pressed against the side wall of the shelf corbel 2, and the other side of the sealing layer 4 is pressed against the side wall of the bottom plate 1. Under the action of the sealing layer 4, the sealing between the shelf corbel 2 and the bottom plate 1 can be improved, and the penetration of water from the gap between the shelf corbel 2 and the bottom plate 1 can be reduced.
[0033] Reference Figure 2 A sealing layer 5 is poured in the gap between the wall panel 3 and the bottom plate 1. In the embodiment of the present application, the sealing layer 5 is a 30 mm thick sealing mortar. Under the action of the sealing layer 5, the gap between the wall panel 3 and the bottom plate 1 can be sealed, thereby reducing the penetration of water through the gap between the wall panel 3 and the bottom plate 1, so that the space enclosed by the wall panel 3 and the bottom plate 1 is a water-free and dry space, which is convenient for the pouring of the base.
[0034] A limit block 6 is fixed on the top surface of the supporting bracket 2. In the embodiment of the present application, the limit block 6 is a right trapezoidal block. The side wall of the limit block 6 abuts against the outer wall of the wall panel 3. The side of the limit block 6 away from the wall panel 3 is an inclined surface. The width of the top of the limit block 6 is smaller than the width of the bottom of the limit block 6. Under the action of the limit block 6, the structural stability of the bottom of the wall panel 3 can be increased. The limit block 6 plays a role in resisting and limiting. When the wall panel 3 is subjected to an outward horizontal force, the limit block 6 can resist the outward force of the wall panel 3, so that the wall panel 3 is more stable and the situation of the wall panel 3 shaking and being unstable is reduced.
[0035] The limit block 6 is a right trapezoidal block, so that the contact area with the top surface of the supporting bracket 2 can be increased, and then the friction force with the supporting bracket 2 can be increased, and further the connection stability between the limit block 6 and the supporting bracket 2 can be increased. The inclined surface of the limit block 6 and the side wall of the wall panel 3 form a triangle with the top surface of the supporting bracket 2, forming a relatively stable structure, which can better provide a supporting force for the wall panel 3. At the same time, the center of gravity of the limit block 6 is relatively low, so that the limit block 6 is not easy to turn over after being subjected to a horizontal force.
[0036] Refer to Figure 1 , a first pull rod 71 is fixed at one end of the casing 8 close to the wall panel 3. The top end of the first pull rod 71 is fixed to the bottom of the side wall of the wall panel 3. A second pull rod 72 is fixed at the end of the casing 8 away from the wall panel 3. The top end of the second pull rod 72 is fixed to the top of the side wall of the wall panel 3. The second pull rod 72 is located above the first pull rod 71. The first pull rod 71, the wall panel 3 and the bottom plate 1 form a triangle in cross section. The triangle has stability. Under the action of the first pull rod 71, the first pull rod 71 can support the bottom of the wall panel 3, so as to further improve the stability of the bottom of the wall panel 3 and reduce the situation of the wall panel 3 shaking and being unstable due to horizontal force. Correspondingly, the second pull rod 72, the wall panel 3 and the bottom plate 1 form a triangle in cross section. Under the action of the second pull rod 72, the second pull rod 72 supports the top of the wall panel 3. When the wall panel 3 is subjected to a horizontal force, the force received by the top of the wall panel 3 is transmitted to the casing 8 through the second pull rod 72, and the casing 8 provides a supporting force for the second pull rod 72, so that the position of the wall panel 3 is more stable and the situation of the wall panel 3 shaking and toppling is reduced.
