Description of the Related Art FIGS. 5 (A) and 5 (B) use a hoist such as a one-to-one pair of electric chain blocks to alternately elevate and lower a formwork and a scaffolding column to pour concrete upward. It is a conceptual diagram which shows the construction method of the conventional concrete formwork construction, FIG. 5 (A) has shown the operation | movement at the time of scaffolding pillar rising, and FIG. 5 (B) has shown the formwork rising. In the figure, a is precast concrete, b is a pair of scaffolding pillars, c is a fixed scaffolding provided on each scaffolding pillar b, d is a formwork, and e is attached to the upper end of each scaffolding pillar b. A hoisting machine such as an electric chain block, f is a pulley attached to the bottom of each scaffolding b, g is a hoisting wire of each hoisting machine e, h is an anchor fixed to already-placed concrete a, and i is A bracket for fixing each scaffolding b to the concrete a that has been cast, j is a reinforcing bar, and k is a separator of the form d. In the conventional concrete formwork construction, when the concrete is spliced to the upper part of the concrete a which has been previously cast to the height shown in FIG. 5 (A), the hoisting wire g is moved from the hoisting machine e to the pulley f below the scaffolding b. It is made a half turn and is attached to an anchor h whose tip is fixed to the cast concrete a, and the bracket i at the bottom of the scaffolding b is removed from the cast concrete a. Then, if the winding machine e is driven in the winding direction,
The hoisting wire g is hoisted up, and the scaffolding pillar b self-elevates to the solid line position in FIG. (A) with the anchor h of the placed concrete a as a reaction force point. When the scaffolding b is raised, the bracket i is fixed to the placed concrete a, the form d of the placed concrete a is removed, the winding wire g is connected to the form d, and the hoist e is wound up.
As shown in FIG. 5 (B), the form d is raised to the upper concrete pouring position. That is, according to the conventional concrete formwork construction in which the formwork and the scaffolding are alternately raised and lowered and the concrete is spliced upward, the wire of the hoisting machine must be reconnected each time the scaffolding and the formwork are raised and lowered. However, it took a lot of time and effort, and the efficiency of concrete formwork construction was significantly impaired.

First, the operation of the present invention will be described with reference to FIG. In the formwork construction device of the present invention consisting of one to one set, the winding wire 5 is wound endlessly on the electric crane type winder 3 and the pulley 4 attached to the upper and lower ends of each scaffolding pillar 2, and the winding wire is wound. 5
The upper and lower scaffolds or the upper and lower sides of the formwork 6 are attached to both ends of the. The lifting scaffold is omitted in the conceptual diagram of FIG. In the figure, 7 is precast concrete, and each scaffolding post 2 of the formwork construction device 1 is precast concrete 7.
It is fixed to the upper and lower brackets 9 and 9 which are detachably attached by anchor bolts 8 and 8 (Fig. 1).
(A)). When the concrete is spliced on top of the cast concrete 7, the reinforcing bars 10 are extended to the top of the cast concrete 7 and the separators 11 and 11 of the formwork 6 and 6 are removed, so that each scroll type hoist 3 By driving the in the winding direction, the molds 6, 6 rise. When the molds 6, 6 are raised to a predetermined position, the separator 11,
11 is put and the molds 6 and 6 are assembled (FIG. 1 (B)). Next, concrete 12 is cast into the above-mentioned molds 6 and 6, and when the concrete 12 is hardened, the brackets 9 and 9 are removed from the anchor bolts 8 and 8, and the respective crane type hoisting machines 3 are driven in the hoisting direction. 6 and 6 are separators 11 and 1
Since it is fixed to the concrete 7 and 12 that has been hardened by 1, the scaffolding posts 2 and 2 themselves instead rise up relative to the formwork 6 and 6 (FIG. 1 (C)). When the scaffolding pillars 2 and 2 are raised to a predetermined position, the brackets 9 and 9 of the scaffolding pillars 2 are attached to the anchors 13 and 13 that are driven into the concrete 7.
Fixed, and proceed with formwork in the same way (Fig. 1

築に好適なことは云うまでもない。FIG. 4 shows, in order, one construction example of constructing caisson bulkheads using the formwork construction apparatus shown in FIG. 3, and the right half of each of the illustrated formwork construction apparatuses. Indicates a process that is one process advanced from the left half. The construction process will be described with reference to the drawings. First, the formwork construction apparatus 1 is hung by a crane or the like at the center position of each partition that constructs the partition wall (FIG. 4 (1)). Next, the elevating scaffolding 16 is raised to an appropriate height, and the projecting plate 17 is projected to assemble the reinforcing bars 21 in the lower stage of the partition wall (FIG. 4 (2)). Next, the overhanging plate 1 of the lifting scaffold 16
7, the box-shaped mold 22 is hung in each section of the partition by a crane or the like, and the molds 22 and 22 on both sides of the partition are assembled by the separator 23 (FIG. 4 (3)). Next, the formwork 22, 2
Concrete 24 is placed in 2 (Fig. 4 (4)). Next, the elevating scaffold 16 is raised and the projecting plate 17 is projected to assemble the reinforcing bar 25 on the upper stage of the partition wall. (FIG. 4 (5)). After hardening the concrete 24 in the lower part of the partition wall, the elevating scaffold 16 is lowered, and the form 22 is fixed to the overhanging plate 17 of the upper elevating scaffold 16 to remove the separator 23 of the form 22.
The mold 22 fixed to the overhanging plate 17 by retracting 7 is contracted and released from the concrete 24 (FIG. 4 (6)). Next, the formwork 2 fixed to the lifting scaffold 16 together with the lifting scaffold 16
2 to the concrete pouring position on the upper part of the bulkhead, and the overhanging plate 17 of the elevating scaffold 16 is overhanged to form the molds 2 on both sides of the bulkhead.
2 and 22 are widened, and both molds 22 and 22 are separated by a separator 2.
Assemble with 3. At this time, the anchor 26 is attached to the separator 23 which penetrates the concrete 24 below the form 22 (FIG. 4 (7)). Next, the elevating scaffold 16 is raised, and concrete 27 in the upper part of the partition wall is placed between the molds 22 and 22, and the elevating scaffold 16 is fixed to the form 22 (FIG. 4).
(8)). Next, the formwork construction apparatus 1 itself is raised to fix the base frame 15 to the anchor 26 (see FIG. 4).
(9)). The formwork construction apparatus 1 itself is lifted by driving the climbing type hoisting machine 3 in the direction opposite to that when the liftable scaffold 16 is raised, so that the formwork 22 is immovable because the liftable scaffold 16 is fixed to the formwork 22. Raised as a reaction point. Next, the mold 22 is contracted and released from the concrete 27, and the above steps are repeated to pour the concrete above the partition wall to complete the partition wall (FIG. 4 (10)). In the actual construction, the above steps may be appropriately changed in order, and the construction example of the caisson partition wall is as follows.
Formwork construction equipment is put into each of the sections that construct the caisson bulkheads, and construction work is carried out in parallel.However, the retaining plates are inserted into the formwork, and the bulkheads are divided as appropriate for construction. Of course, it is possible. Needless to say, this formwork construction apparatus is not limited to the partition wall of the caisson and is suitable for construction of earth retaining walls and other general wall bodies.
