Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a steel sheet pile cofferdam supporting device for building construction. Background Art

[0002] The steel sheet pile cofferdam support device for construction is a device used for temporary cofferdam support in civil engineering projects. It is mainly used to provide support and protection for the construction site during earth excavation, foundation pit support and other construction processes. It can provide a stable support structure to prevent earth collapse and ensure construction safety. The device is suitable for construction sites under various soil and terrain conditions, including soft soil, silt, sand, etc., and has strong applicability.

[0003] However, most of the steel sheet pile cofferdam support devices used in construction now have the following problems:

[0004] For example, a support device for steel sheet piles for bank protection with announcement number CN214883426U, although it can provide stable support, its support length is limited. The width of the steel sheet pile cofferdam used in different construction sites is different, and the support cannot be adjusted according to the size and width of the steel sheet pile cofferdam. Therefore, the user needs to reset the support device every time the foundation pit is constructed, which increases the labor cost of construction and affects construction efficiency; at the same time, a foundation pit support and protection device with publication number CN202122198893.3 can provide support and anti-slip through the cooperation of the support plate and anti-slip particles, but the support plate and the anti-slip particles are mostly integrated. The anti-slip particles on the support plate are prone to wear after long-term use, which is easy to affect the support stability during subsequent use, and it is inconvenient to disassemble and replace the support plate and the anti-slip particles.

[0005] Therefore, the applicant has made improvements to this and proposed a steel sheet pile cofferdam support device for construction. Utility Model Content

[0006] The purpose of the utility model is to address the existing problems that the support cannot be adjusted according to the size and width of the steel sheet pile cofferdam, and it is inconvenient to easily disassemble and replace the support plate and the anti-skid particles.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A steel sheet pile cofferdam support device for construction includes a steel sheet pile cofferdam body, a mounting plate and a spring, wherein a mounting plate is arranged inside the steel sheet pile cofferdam body, a rotating member is rotatably connected to the mounting plate, a first bevel gear is fixedly connected to the rotating member, a second bevel gear is meshingly connected to the first bevel gear, a threaded rod is fixedly connected to the second bevel gear, a threaded sleeve is threadedly connected to the threaded rod, a connecting plate is fixedly connected to the threaded sleeve, and a guide rod is fixedly connected to the connecting plate.

[0009] Preferably, the rotating member is fixedly connected to the center of the first bevel gear, the second bevel gears are symmetrically distributed on the left and right sides of the first bevel gear, and the second bevel gears correspond one-to-one with the threaded sleeve through the threaded rod.

[0010] Preferably, the guide rod is limitedly slidably connected in the mounting plate, a support plate is provided on the connecting plate, the threaded rod is fixedly connected to the center of one side of the second bevel gear, and the end face of the guide rod is in contact with the inner side face of the mounting plate.

[0011] Preferably, an anti-slip pad is fixedly connected to the support plate, a fixing plate is arranged inside the support plate, the springs are symmetrically distributed on the left and right sides of the fixing plate, and the springs correspond one-to-one with the first clamping blocks through a limiting plate.

[0012] Preferably, a spring is fixedly connected inside the fixing plate, the other end of the spring is fixedly connected to a limiting plate, the side end surface of the limiting plate is fitted with the inner side surface of the fixing plate, and the first clamping block is fixedly connected to the center part of one side of the limiting plate.

[0013] Preferably, a pull plate is fixedly connected to the limit plate, a second clamping block is fixedly connected to the fixed plate, a first clamping block is fixedly connected to the limit plate, and the second clamping blocks are equidistantly distributed on the fixed plate.

[0014] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0015] 1. Through the threaded sleeve, when supporting the inside of the steel sheet pile cofferdam body, the rotating part on the mounting plate can be rotated, and the rotating part drives the first bevel gear to operate. When the first bevel gear rotates, the threaded rod can be smoothly driven to rotate through the second bevel gear. When the threaded rod rotates, the threaded sleeve can be pushed to move outward. When the threaded sleeve moves, it can provide stable support through the support plate and anti-skid pad installed on the connecting plate. When the connecting plate moves, it can move smoothly through the guidance of the guide rod, and can be used for stable support according to the usage.

[0016] 2. Through the set fixing plate, when the supporting plate on the connecting plate needs to be disassembled and replaced, the pulling plates on both sides of the fixing plate can be squeezed, and the pulling plates drive the limiting plates to move. The limiting plates can squeeze the springs when moving, and at the same time the limiting plates drive the first clamping block to disengage from the connecting plate and the supporting plate and retract into the fixing plate. When the fixing plate is unobstructed, the fixing plate can be taken out from the connecting plate and the supporting plate, and the supporting plate on the connecting plate can be disassembled and replaced. When installing a new supporting plate, the second clamping block on the fixing plate can be inserted into the connecting plate and the supporting plate, and then the pulling plates on both sides are released. The limiting plates are driven to reset under the push of the springs, and the limiting plates simultaneously push the first clamping block to engage in the connecting plate and the supporting plate for engagement and fixation, thereby improving the efficiency of disassembly and replacement.
