Description

Technical Field

[0001] The utility model relates to the technical field of climbing formwork, in particular to a hydraulic climbing formwork. Background Art

[0002] At present, the hydraulic climbing formwork mainly adopts the method of overall climbing. The existing technology includes a utility model patent for a new type of hydraulic climbing formwork with application number 202121494897.X. It is necessary to wait until the wall concrete strength reaches 15MPa before the climbing formwork can climb on the wall for the next step of construction, which affects the construction efficiency. In addition, the strength of the newly poured wall is relatively low. The overall climbing of the climbing formwork can easily cause the newly poured concrete to deform under pressure, reduce the quality of the project and easily affect the safety of the construction. Utility Model Content

[0003] The purpose of the implementation mode of the utility model is to provide a hydraulic climbing formwork, aiming to solve the problems of low construction efficiency of the hydraulic climbing formwork in the prior art, easy deformation of concrete under pressure, resulting in poor project quality and affecting construction safety.

[0004] In order to solve the above technical problems, the utility model provides a hydraulic climbing formwork, including a formwork, wherein the formwork is installed on a formwork platform, a casting platform is fixedly installed on the upper end of the formwork platform through a fixing device, a lifting platform is fixedly installed below the formwork platform, and a hanging platform is connected to the bottom of the lifting platform through a hydraulic cylinder; the lifting platform is connected to a guide rail, and the guide rail is fixedly connected to a wall through a fixing device, and there are rollers on the hanging platform, which are in rolling contact with the wall, and the lifting platform and the hanging platform are fixed to the wall through a fixing device.

[0005] The widths of the pouring platform, the template platform, the lifting platform and the hanging platform increase in sequence.

[0006] The part of the template platform with a wider width compared to the casting platform is the third safety protection platform, the part of the lifting platform with a wider width compared to the template platform is the second safety protection platform; the part of the hanging platform with a wider width compared to the lifting platform is the first safety protection platform.

[0007] Protective fences are installed on the edges of the first safety protection platform, the second safety protection platform and the third safety protection platform.

[0008] More than one lifting device is installed on the casting platform.

[0009] The lifting device has a telescopic boom.

[0010] A hydraulic power device is installed between the lifting platform and the guide rail.

[0011] Beneficial Effects

[0012] Compared with the prior art, the implementation mode of the utility model is as follows: after the concrete of the wall is solidified, the hanging platform continues to be fixed on the wall by the fixing device and does not move, and the lifting platform moves upward through the guide rail. At the same time, the oil cylinder between the hanging platform and the lifting platform is lifted upward, giving the lifting platform an upward force while supporting the lifting platform, thereby ensuring the safety of the lifting platform's ascent, reducing the pressure on the newly cast wall, and avoiding wall deformation. The utility model does not need to wait until the concrete strength of the newly cast wall reaches 15 MPa before further construction can be carried out in advance, which greatly improves the construction efficiency. After the strength of the newly cast concrete is further increased to reach 15 MPa, the hanging platform is pulled up by the hydraulic cylinder, and the rollers on the hanging platform can make it more convenient for the hydraulic cylinder to pull up the hanging platform.

[0013] The utility model has a first safety protection platform, a second safety protection platform and a third safety protection platform, and the edges of the first safety protection platform, the second safety protection platform and the third safety protection platform are equipped with protective fences, which greatly improves the safety of the climbing formwork, avoids the life safety caused by improper operation of personnel falling, and avoids the safety problems caused by falling objects to the people below. Construction materials can be piled on the first safety protection platform, the second safety protection platform and the third safety protection platform, and the construction materials are transported by the lifting mechanism, which can improve the construction efficiency. Because the lifting platform is fixed on the wall with greater concrete strength before being pulled up by the oil cylinder, it can withstand greater pressure, and the first safety protection platform can stack more construction materials, which greatly increases the efficiency of construction material transportation.
