Description

TECHNICAL FIELD

[0001] The present application relates to the field of building construction equipment, and particularly relates to a hydraulic climbing form windproof structure and a construction method, mainly applied to the construction process of high-rise buildings, bridge piers and other high-rise structures, to improve the stability and safety of the hydraulic climbing form in strong wind environment. BACKGROUND

[0002] In modern building construction, hydraulic climbing form, as an advanced construction equipment, is widely used in the construction of high-rise buildings, bridge piers and other high-rise structures. Hydraulic climbing form has the advantages of high construction efficiency, good construction quality, and reusability, which can effectively shorten the construction period and reduce the construction cost. For example, in the construction of some super high-rise buildings, the hydraulic climbing form can automatically climb with the floor rising, without the need to frequently disassemble and install the formwork, greatly improving the construction efficiency. However, in coastal areas and some areas with strong winds, the hydraulic climbing form faces severe windproof challenges during construction. Strong winds can cause the hydraulic climbing form to sway, displace, or even collapse, seriously threatening the safety of construction personnel and the smooth progress of the project. According to relevant statistical data, in some past building construction projects, due to inadequate windproof measures for the hydraulic climbing form, several safety accidents occurred in strong wind weather, causing huge casualties and economic losses.

[0003] Traditional hydraulic climbing form structures often do not adequately consider windproof performance in design. The wind-resistant stability of the frame structure is insufficient, and it is prone to deformation under strong wind. At the same time, the connection between the formwork and the frame is not firm enough, and under the action of wind, the formwork may loosen or fall off. In addition, the existing hydraulic climbing form lacks effective measures to deal with different wind grades, and cannot adjust the structure state in time according to the change of wind force to ensure construction safety.

[0004] In terms of construction methods, the existing operation process has many defects after the typhoon warning is issued. For example, the reinforcement operation of the formwork and the frame is not standardized and systematic, resulting in poor reinforcement effect. Moreover, there is no clear and reasonable construction guidance under different wind grades, and construction personnel often do not know what to do, and cannot take the correct response measures.

[0005] In some existing hydraulic climbing form windproof technologies, although measures such as increasing the density of attached wall supports and setting double anti-falling devices are taken, these methods still have certain limitations. Increasing the density of attached wall supports will increase the construction cost and difficulty, and under the action of strong wind, the attached wall supports themselves may also fail under excessive pressure. The double anti-falling device is mainly designed to prevent the formwork from falling, and has limited effect on improving the wind-resistant stability of the overall structure.

[0006] In summary, the existing hydraulic climbing formwork has obvious deficiencies in windproof structure and construction method, and cannot meet the demand of safe construction in strong wind environment. Therefore, it has important practical significance and engineering application value to develop an efficient and reliable hydraulic climbing formwork windproof structure and construction method.

The opposite pulling screw rod 103 is used for fixing the inner formwork 104 and the outer formwork 105 together in the formwork closing condition, and fixing the outer formwork 105 on the steel bar or the already poured wall in other conditions. The cable-stayed seat 100 is used for tensioning the formwork, enhancing the stability of the formwork. The basket bolt 101 is installed on the upper platform, used for connecting with the steel bar, further enhancing the connection between the formwork and the frame.

The reinforcing member 108 is used for connecting the formwork withdrawing device and the upper platform frame, enhancing the overall stability of the frame.

[0029] The formwork state adjusting assembly: in the formwork closing condition, through specific mechanical structure or operating device, the inner and outer formworks can be accurately at the same height and smoothly closed, so as to carry out the subsequent fixing operation.

[0030] Construction method comprising the above structure: Step one, typhoon warning response: when receiving the typhoon warning signal, according to the forecast of the Central Meteorological Observatory, stop lifting the climbing formwork frame and pouring concrete within 3 days before the typhoon arrives. Immediately check the formwork and frame body to prepare for subsequent reinforcement work.

[0031] Step two, connection inspection and reinforcement: before the typhoon arrives, comprehensively check all connections. Focus on checking whether the spring washer is used according to the design requirements for bolt connections, and use double nuts on important bolt connections and ensure tightening.
