Description

Technical Field

[0001] The present invention relates to the field of building construction, and more specifically, to a supporting device for steel sheet piles for cofferdams. Background Art

[0002] Steel sheet piles are a type of steel structure with linkage devices on the edges that can be freely combined to form a continuous and tight retaining wall or water retaining wall.

[0003] Since the steel sheet piles mainly bear the pressure from the outside, the inner side of the cofferdam structure formed by them needs to be supported. The usual support structure is a support column, that is, the support column is directly tilted to support the inner side of the steel sheet pile, or placed horizontally and directly supported on the inner wall of the steel sheet pile on both sides of the cofferdam. Regardless of the support method, the support column needs to be welded and fixed. This support method is not only slow to construct, but also easy to cause the support column to slip due to factors such as rust, and has poor reliability.

[0004] Therefore, a new type of supporting device for steel sheet piles for cofferdams is needed to solve the above problems. Summary of the invention

[0005] One purpose of the present invention is to solve the problems of poor reliability and slow construction of the existing steel sheet pile support device for cofferdam.

[0006] According to one aspect of the present invention, there is provided a supporting device for steel sheet piles for cofferdams, comprising support columns and a frame, wherein the frame comprises a mounting seat and a hanging frame, wherein the hanging frame is fixed to one side of the mounting seat and is used for hanging on the top of the steel sheet pile, the mounting seat is horizontally arranged and is used for mounting the support columns, one end of the mounting seat abuts against the inner side surface of the steel sheet pile, and when in use, both ends of the support column are mounted on the mounting seat, and a fixing mechanism is provided on the mounting seat.

[0007] Through this solution, the scaffolding is directly erected to the top of the steel sheet pile, and the support columns are directly erected and set without welding, which greatly improves the efficiency of support construction; the fixing mechanism can temporarily fix the support columns, and the erection arrangement will not cause safety accidents due to welding quality and rust problems at the welding points, which greatly improves safety during use.

[0008] Preferably, a connecting rod is vertically fixed to one end of the hanging bracket, and the bottom of the connecting rod is fixed to the mounting seat; a stabilizing frame is fixed to the other end of the hanging bracket, and the stabilizing frame abuts against the outer side surface of the steel sheet pile.

[0009] Through this solution, the stabilizer and the mounting base clamp the steel sheet piles together to prevent the hanger from sliding left and right, thereby improving the stability of the device during use.

[0010] Preferably, the stabilizing frame comprises a stabilizing plate, the width of the stabilizing plate is not less than twice the width of the steel sheet piles, and the stabilizing plate is arranged parallel to the steel sheet piles.

[0011] Through this solution, the stabilizing plate can reach the back of the steel sheet pile to increase the contact area, thereby reducing the pressure and improving the protective effect on the steel sheet pile.

[0012] Preferably, a top column is provided on the inner side surface of the stabilizing plate, and the top column is arranged perpendicular to the stabilizing plate and abuts against the recess of the steel sheet pile.

[0013] Through this solution, the top column is inserted into the depression of the steel sheet pile to fix the device laterally, avoiding the support column from falling due to left and right sliding, thereby improving stability during use; and it can also support the middle part of the stabilizing plate, avoiding excessive external pressure causing depression and damage to the stabilizing plate.

[0014] Preferably, the hanging rack includes two hanging rods arranged in a "V" shape, the angle between the hanging rods is consistent with the angle of the two side walls of the steel sheet pile, and the hanging rods are respectively placed on the top of the two side walls of the steel sheet pile.

[0015] Through this solution, the contact area between the steel sheet pile and the hanging rod can be increased, so that the point force is increased to the surface force, and the damage of the hanging rod caused by excessive local pressure is avoided.

[0016] Preferably, the fixing mechanism comprises a stopper, and the stopper is at least arranged on two sides of the mounting seat.

[0017] Through this solution, the stopper can limit the support column, preventing the support column from sliding sideways out of the mounting seat when it is collided or squeezed, causing danger.

[0018] Preferably, the top column passes through the stabilizing plate and is slidably connected to the stabilizing plate, and a magnetic suction cup is provided at the end of the top column.

[0019] Through this solution, the magnetic suction cup can be firmly adsorbed to the outer wall of the steel sheet pile to further improve the stability of the device; the slidingly connected top column can control the magnetic suction cup to move away from or close to the steel sheet pile to facilitate the installation and placement of the device.

[0020] Preferably, the fixing mechanism includes a positioning hole, and the positioning hole is arranged on a vertical surface of the mounting seat toward the end of the support column. The end of the support column is provided with a positioning pin matching the positioning hole, and the height of the positioning hole is consistent with the height of the magnetic suction cup.

[0021] Through this solution, the positioning pin can be inserted into the positioning hole for positioning under the attraction of the magnetic suction cup, so as to improve the stability of the support column during the supporting process and avoid it from falling due to vibration.

[0022] Preferably, a slide groove is provided at the top of one end of the support column, the positioning pin is slidably connected to the slide groove, and a lever is provided at the top of the positioning pin.

[0023] Through this solution, the positioning pin mainly serves to prevent it from detaching upwards. After the magnetic suction cup is easily disassembled, the lever can push the positioning pin to disengage from the positioning hole.

[0024] One of the technical effects of the present invention is that the device has a simple structure, is easy to use, and does not require welding operations, which greatly improves the support operation efficiency of steel sheet piles; and the support reliability is higher, and the support column will not slip due to problems such as desoldering and rust, which greatly improves safety during use.

[0043] In this embodiment or other embodiments, the stabilizing frame 230 includes a stabilizing plate 231, the width of the stabilizing plate 231 is not less than twice the width of the steel sheet pile 300, and the stabilizing plate 231 is arranged parallel to the outer side of the steel sheet pile 300. The stabilizing plate 231 can reach the back of the steel sheet pile 300 to increase the contact area, thereby reducing the pressure and improving the protective effect on the steel sheet pile 300.

[0044] In this embodiment or other embodiments, a top column 232 is provided on the inner side of the stabilizing plate 231, and the top column 232 is arranged perpendicular to the stabilizing plate 231 and abuts against the depression of the steel sheet pile 300.
