A drive mechanism may be included so that the carriage 42 can be moved in the traveling direction of the carriage 41 on the lift table 42b.

Next, the steps of installing the floor formwork and the steps of constructing the beam using the floor formwork installing device 4 described above will be described with reference to FIGS.
This will be described with reference to FIG.

First, one beam form 7 is transported from the stockyard 13 to the hoisting lift 81 by the forklift 86, is carried to the construction floor by the hoisting lift 81, and is transferred from the hoisting lift 81 to the roller conveyor 82. . Then, the placing table 43 of the floor form setting device 4 is positioned below the roller conveyor 82, the placing table 43 is raised, and the floor form 7 is supported by the placing table 43 of the floor form installing device 4, By moving the floor form installation device 4, the floor form 7
Is transferred from the roller conveyor 82 to the mounting table 43 of the floor form installation device 4. Then, if necessary, the mounting table 43 of the floor form installation device 4 is lowered.

The floor form 7 is held by the floor form holding piece 44b of the floor form holding mechanism 44 by operating the actuator 44a of the floor form setting device 4. At this time, by operating the mounting table moving mechanism 46, the positions of the floor form 7 and the beam member 6 on which the floor form 7 is installed are approximately aligned (arrow A ″).

In this state, as shown in FIG. 17, by operating the mounting table tilting mechanism 45 to swing the mounting table 43 around the shaft 43a, the plane projection length of the floor form 7 in the longitudinal direction is projected. The floor formwork 7 is tilted in the longitudinal direction until L1 becomes shorter than the distance L2 between the beam members 6 on which the floor formwork 7 is installed (arrow B ″). While maintaining this state, the lifting mechanism 42 is operated. Thus, the floor formwork 7 is lifted together with the mounting table 42 (arrow C ″), and is passed between the beam members 6 on which the floor formwork 7 is installed from below to above. Then, the platform tilting mechanism 45 is operated to swing the platform 43 around the shaft 43a in the direction opposite to the direction in which the floor frame 7 is returned to the horizontal state (arrow D ″), and the lifting mechanism is moved. By operating 42, the floor formwork 7 is lowered together with the mounting table 42 (arrow E ″), and the floor formwork 7 is lowered onto the beam member 6. At this time, the mounting table moving mechanism 46
The floor form 7 and the beam member 6 are aligned with each other by operating (arrow F ″).

Then, as shown in FIG. 19, by operating the floor form moving mechanism 47, the floor form 7 is pushed and moved to the side of the previously installed floor form 7a (arrow G "), and one sheet is placed. Installation of the floor formwork 7 is completed.

When the floor formwork 7 cannot be lowered at a right angle to the beam member 6, as shown in FIG. 18, the floor formwork moving mechanism, that is, the floor formwork moving mechanism 47 is moved. One of the floor form moving pieces 47b is connected to the actuator 4
By operating with 7a, the installation direction of the floor form 7 can be corrected (arrows G1 ", G2").

By repeating the above steps, the floor formwork 7 can be installed on the beam member 6 without a gap, but the last floor formwork is installed with the width of the floor formwork first. If it is formed to have the same width W1 as the gap between the floor molds 7a, 7a, it cannot be installed by the above method. For this reason, as shown in FIG. 20, the last floor formwork 7b, 7b has the width W1 of the gap between the floor formwork 7a, 7a, which is the floor formwork width W2 previously installed.
Floor molds 7b and 7b that are narrower and have the width W2 of the two floor molds 7b and 7b added to form the width W1 of the gap between the floor molds 7a and 7a. After lowering the frames 7b, 7b on the beam member 6 by the same method as described above,
By using an appropriate method, the two floor molds 7b, 7b
It should be installed in the gap between a and 7a (arrow H ").

After that, floor rebars are installed on the floor formwork and concrete is poured to complete the construction of the floor.

In order to improve the efficiency of the concrete pouring work, part of the concrete pouring in the pillar building process, the beam building process, and the floor building process, for example, in the beam building process and the floor building process. Concrete pouring or all can be done simultaneously.

In order to avoid a decrease in work efficiency due to the work of removing the formwork, a driving formwork is used for the pillar formwork, beam formwork and floor formwork of the mechanized construction method of the reinforced concrete building of the present invention. Is desirable. In this case, as the formwork, a driving formwork is used in which the base is made of a cement extrusion plate having a hollow portion continuous in the longitudinal direction, and if necessary, a reinforcing bar is provided in the hollow portion for reinforcement. As a result, it is possible to manufacture a large amount of molds at low cost, and further, since the manufactured molds have high dimensional accuracy, installation work by a machine is facilitated and installation accuracy is improved. be able to. In addition, if necessary, prestress can be introduced into the reinforcing bar arranged in the hollow part of the driving form, whereby the strength of the form can be remarkably improved, and the number of supporting works to be erected. It is possible to improve the workability and the productivity by simplifying the steps of erection of the support work and removal of the support work in the subsequent process. Also,
If necessary, it is possible to fill the hollow part through which the reinforcing bar is inserted with a filler, which allows the reinforcing bar to be positioned as a part of a reinforced concrete building, and simplifies the assembly of the reinforcing bar. The installation accuracy of the rebar can be improved.
