Embodiment Construction
[0021] The present invention will be further described below with reference to the accompanying drawings.
[0022] A construction method for initial installation of a hydraulic climbing formwork, using a frame body comprising a lower frame body 6, an upper frame body 9, a large steel formwork 3, a guide rail 10 and a hydraulic drive mechanism 5, including the following construction process:
[0023] A. During the construction of the first floor or podium roof 2 structure, reserve the installation hole 21 of the lower frame according to the plane position of the frame (refer to figure 1 ), tie the first layer of reinforcement;
[0024] B. Use the large steel formwork 3 of the frame to pour the first layer of wall, and pre-embed the climbing cone 4 in the positioning hole of the large steel formwork 3 (refer to figure 1 );
[0025] C. Remove the large steel formwork 3 of the climbing formwork after the first wall reaches the strength requirement;
[0026] D. Install the wal...

The invention relates to an initial mounting construction method for a hydraulic creeping formwork in constructional engineering, which is characterized in that the mounting process comprises the following steps: reserving a mounting hole for a lower frame body of the creeping formwork when the structure of a fist floor is constructed; using a large-scale steel formwork to combine and cast thewall body on the first layer, and embedding a creeping cone; dismantling the large-scale steel formwork of the creeping formwork; mounting a wall-attached device, a guide rail and the lower frame body, and mounting a main platform, an upper frame body and the large-scale steel formwork on the lower frame body; binding the two-layer wall body by steel bars, combining the formworks, embedding the creeping cone, and casting concrete for the two-layer wall body; withdrawing the formworks and mounting the wall-attached device; and carrying out the prior creeping formwork processes later. The construction technique has the advantages that the construction technique overcomes the defect of spatial requirement that the initial mounting of a creeping frame body needs two-layer height in the prior self-creeping hydraulic creeping formwork technique; the creeping cone is embedded in the reserved hole of the large steel formwork, so as to ensure accurate position for initial mounting of a creeping guide rail, and improve mounting efficiency and mounting quality; and the initial mounting of the creeping formwork is finished on the first floor or the skirt floor, and a construction platform does not need to be set, so as to shorten construction period greatly and save construction cost.
Description
technical field [0001] The invention relates to construction engineering technology, in particular to hydraulic climbing formwork construction technology for high-rise buildings. Background technique [0002] Self-climbing hydraulic climbing formwork construction technology is widely used in high-rise buildings. Traditional self-climbing hydraulic climbing formwork construction needs to use ordinary formwork to construct two layers of reinforced concrete walls as the carrier of climbing formwork construction. In the reinforced concrete wall, the climbing formwork guiding embedded parts are installed, and the construction platform needs to be built for installation in the initial installation stage. This method has the following disadvantages: [0003] 1. It is difficult to set the climbing formwork guide and embedded parts accurately when constructing two-layer reinforced concrete walls with ordinary formwork; [0004] Two, the construction period is delayed, the formwork m...
