Embodiment 1

[0033] In this embodiment, the construction of the cast-in-situ arc-shaped reinforced concrete wall 1 is taken as an example. The inner formwork 20 is assembled by wooden formwork, and the outer formwork is an assembled all-steel formwork, and the outer formwork is vertically spliced ​​by three shaped sub-formworks. Formed, respectively, the upper shaping sub-template 11, the middle shaping sub-template 12 and the lower shaping sub-template 14, and the adjacent two shaping sub-templates are threadedly connected by a connecting screw, and the following combination Figure 1 to Figure 11 Describe the formwork reinforcement device of this embodiment, which includes: a pair of parallel and spaced connecting rods 15, a supporting member, three buckle members 17, and a plurality of wall-through screws 18, and the supporting member is fixedly connected to the lower part At the bottom of the shaped sub-formwork 14, a pair of connecting rods 15 are vertically arranged on the outside of ...

Embodiment 2

[0039] combine Figure 1 to Figure 11 Illustrate the arc combined shaped steel formwork 10 of the present embodiment, it comprises at least two shaped sub-formworks, and a plurality of formwork reinforcement devices as described in embodiment 1, the shaped sub-formworks are assembled and screwed together vertically and horizontally, multiple A template reinforcement device is arranged vertically and at intervals along the horizontal extension direction of the assembled shaped sub-formwork, and the supporting parts of the formwork reinforcement device are fixedly connected to the shaped sub-formwork at the bottom, and a pair of connecting rods 15 are vertically arranged on the outside of the shaped sub-formwork. The bottom of the connecting rod 15 is detachably connected to the supporting member, at least two buckle parts 17 are arranged along the length direction of the connecting rod 15, and at least one buckle part 17 is correspondingly arranged on each sub-formwork for shapi...

Embodiment 3

[0043] combine Figure 12 to Figure 16 Illustrate the use method of arc-shaped combined shaped steel formwork 10 of the present invention, concrete steps are as follows:

[0044] Such as Figure 12 As shown, the pre-embedded steel bars of the arc-shaped reinforced concrete shear wall to be poured in the current layer are bound, the arc-shaped inner formwork 20 is set up, and three shaped sub-formworks are hoisted in turn, which are respectively the lower shaped sub-formwork 14, the middle shaped sub-formwork 12 and The upper shaped sub-formwork 11, three shaped sub-formworks are assembled vertically and preliminarily connected into a piece of shaped steel formwork by connecting bolts 13, such as Figure 13 As shown, a plurality of formwork reinforcement devices are arranged vertically and at intervals along the horizontal extension direction of the shaped steel formwork, the support parts of the formwork reinforcement devices are fixed on the outer bottom of the shaped steel ...

Abstract

The invention relates to a steel formwork reinforcing device, an arc-shaped combined shaping steel formwork and a using method thereof, which aims to solve the problems that in an existing formwork splicing and reinforcing mode, the flatness of a wall is difficult to guarantee, and overall hoisting and lifting cannot be achieved. The formwork reinforcing device comprises a pair of connecting rods, bearing pieces, buckling pieces and through-wall screws, wherein the bearing pieces are fixedly connected to the bottom of a shaping sub-formwork, the bottoms of the pair of connecting rods are inserted into the bearing pieces, the connecting rods are detachably connected to the shaping sub-formwork through the buckling pieces, one end of the through-wall screws sleeve the connecting rods, and the other ends of the through-wall screws penetrate through an inner formwork and an outer formwork and then are locked and fixed. The arc-shaped combined shaping steel formwork comprises the shaping sub-formworks and the formwork reinforcing devices, wherein a plurality of shaping sub-formworks are spliced and connected in a threaded mode, and a plurality of formwork reinforcing devices are vertically arranged at intervals in the horizontal extending direction of the shaping sub-formworks. The using method comprises the steps that the arc-shaped combined shaping steel formwork is assembled and is connected with the inner formwork, and after pouring of a current-layer wall is completed and formwork removal is conducted, the shaping steel formwork is integrally lifted to pour an upper-layer arc-shaped reinforced concrete shear wall.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a steel formwork reinforcement device, an arc-shaped combined shaped steel formwork and a method for using the same. Background technique [0002] Cast-in-place reinforced concrete walls include straight walls, T-shaped walls, curved walls, etc. The main types of formwork and reinforcement systems used in cast-in-place reinforced concrete walls include: wood formwork square wood back corrugated wall-through screw reinforcement system, aluminum formwork steel back-corrugated wall through-wall screw reinforcement system, all-steel large formwork wall-through screw reinforcement system, finalized Small steel formwork scattered pull piece or steel back corrugated screw reinforcement system, etc. Among them, the wood formwork square wood back corrugated wall screw reinforcement system is suitable for all kinds of cast-in-place reinforced concrete walls. When pouring cur...
