Embodiment 1

[0078] Embodiment 1 Referring to Figure 1-6, the steps of using the hydraulic climbing formwork to construct the wall:

[0079] (1), see Figure 1, bind the steel bars at the initial layer, install the formwork system and hydraulic lifting system, and connect the formwork system and the operating platform system into a whole by the hydraulic lifting system.

[0080] (2), referring to Fig. 2, pour concrete 25 in formwork by conventional construction method.

[0081] (3), referring to Fig. 3, concrete maintenance; During this period, the reinforcement 26 of the upper part is bound.

[0082] (4) When the concrete reaches the demoulding strength, the pull bolts of the formwork system are removed, and the formwork is retreated 80mm from the concrete by the stripper, see Figures 7 and 8.

[0083] (5), referring to Fig. 4, the supporting rod 6 descends to the concrete top surface or the top surface backing plate.

[0084] (6) Fix the support rod to the concrete top surface, see Figu...

Embodiment 2

[0101] Embodiment 2 Referring to Fig. 12, the steps of using the hydraulic climbing formwork to construct the column:

[0102] (1), see Figure 1, bind the steel bars at the initial layer, install the formwork system and hydraulic lifting system, and connect the formwork system and the operating platform system into a whole by the hydraulic lifting system.

[0103] (2), referring to Fig. 2, pour concrete 25 in formwork by conventional construction method.

[0104] (3), referring to Fig. 3, concrete maintenance; During this period, the reinforcement 26 of the upper part is bound.

[0105] (4) When the concrete reaches the demoulding strength, the pull bolts of the formwork system are removed, and the formwork is retreated 80mm from the concrete by the stripper, see Figures 7 and 8.

[0106] (5), referring to Fig. 4, the supporting rod 6 descends to the concrete top surface.

[0107] (6), use the semi-conical cast steel wedge to fix the supporting rod and the perforated hole on...

Abstract

The invention discloses a liftable hydraulic climbing mould and construction method, which comprises the following parts: mould system, hydraulic elevation system and operation platform system, wherein the mould system connects two moulds through extended bolt, whose back connects the steel back deck; the stripper is set on the mould at each space; the liftable jack of hydraulic elevation system crosses on the top of support rod, which connects the support ridge cross-shape; the elevation rack and operation system are connected under the support ridge; the pillar of elevation rack contains moving support leg and channel clamp; the moving support leg contains horizontal extension lead-screw in the clamp, which connects the mould back ridge; the bottom of elevation pillar connects the adjustment lead-screw vertically.

Description

1. Technical field [0001] The invention relates to a building construction climbing formwork, in particular to a liftable hydraulic climbing formwork. 2. Background technology [0002] Climbing formwork is an advanced formwork technology suitable for the construction of vertical structures of cast-in-place reinforced concrete in high-rise buildings or towering structures. Climbing formwork is a formwork that is attached to the building structure and rises layer by layer with the construction of the structure. When the structural engineering concrete reaches the demoulding strength and is demoulded, the formwork does not fall to the ground, relying on mechanical equipment and supports to climb the formwork and climbing formwork device up one level, positioning and tightening, and repeated cycle construction. [0003] Foreign climbing forms mostly use the embedded parts of the wall as the support body, and the hydraulic cylinder is used as the power. The climbing formwork fra...
