Embodiment Construction
[0029] Hereinafter, the inverse hydraulic die-cutting device and the die-reducing method thereof proposed by the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will be more apparent from the following description and claims. It should be noted that all the drawings are in very simplified form and use inaccurate scales, which are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.
[0030] to combine figure 1 and Figure 4, describe in detail the hydraulic formwork lowering device 100 according to an embodiment of the present invention. The hydraulic formwork lowering device 100 is used for hoisting the formwork system 4 of the underground reinforced concrete structure cast on site. The underground reinforced concrete structure includes several layers of reinforced concrete floors (or be...

The invention provides a reverse method hydraulic mold lowering device and a method thereof, which belong to the field of building construction and are used to solve the problems that the existing reverse method mold lowering device cannot be used universally, has low efficiency, and requires multiple disassembly and assembly of formwork systems. The hydraulic mold lowering device of the reverse method includes a stressed suspender assembly, an upper bearing support, a lower bearing bearing and an oil cylinder. Including two and a half nuts, nut sleeves and open gaskets, the oil cylinder is a hollow structure, and the length of the stressed boom assembly can be adjusted according to the actual situation to meet the needs of different projects. The oil cylinder drives the stressed boom assembly and the formwork to lower to achieve efficient reduction Formwork; the method of dropping the formwork can avoid the situation that the formwork needs to be disassembled and assembled many times in the construction of the reverse method. The invention provides a reverse hydraulic mold lowering device and a mold lowering method thereof, which can effectively reduce engineering cost, improve work efficiency and reduce labor intensity of operators.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a reverse hydraulic mold lowering device and a mold lowering method thereof. Background technique [0002] With the rapid development of the city, in the field of urban construction, especially in the construction of deep foundation pits in soft soil geological structures (such as Shanghai), the upside-down method of construction is short due to its short construction period, high safety, and adverse effects on surrounding buildings. (Structure) The advantages of small impact on buildings have attracted more and more attention from people, and have been applied to more and more engineering projects. [0003] The traditional reverse method is to continue to over-excavate a certain space after digging to the design elevation, and use this part of the over-excavation space to build a formwork system and formwork support structure for the reinforced concrete structure (floor or b...
