In FIG. 10, the back surface of the standing mold 1 is covered with a fixed net 5 with a clearance, and a bag-like portion 22 is formed between the fixed net 5 and the mold 1, and a stone is placed in the bag-like portion. It shows another embodiment of the present invention to be charged.

This will be explained by taking as an example the case where the mold 1 and the fixed net 5 in the above-mentioned embodiment are used, and the fixing cords 12a and 12b above and below the fixed net 5 are the same as above on the back side of the mold. Lower and upper connecting cords 10a,
Corresponding to 10b, the tip portion of the connecting cord and the tip portion of the fixing cord are fixedly connected 23 by means of binding or the like, and the bag-like portion 22 is formed on the back surface side of the formwork by the fixing net. . After that, the stone 3 is put into the bag-shaped portion 22, and at that time,
By filling the gap G formed between the stone 3 and the mold 1 with the filler 13 so that the bag-shaped portion 22 is swollen with the stone, the back surface of the mold 1 is processed in the same manner as described above. Stones 3 are piled up along with. Subsequent steps of concrete pouring and demolding are the same as those in the above embodiment.

In each of the above-mentioned embodiments, the fixed net is fixed to the mold by the connecting member consisting of the connecting cord 10 protruding to the back side of the form and the fixed string 12 protruding from the fixed net. The member may be constructed with a single continuous string. For example, the connecting cord can be formed long, and its end portion can be passed through the mesh of the fixed net and connected to the fixed net in a fixed state by binding or the like. Alternatively, the length of the fixing cord may be increased, and the fixing cord may be inserted into a through hole provided in the mold toward the front side of the mold. For example, the end portions of the adjacent fixing cords may be bonded to each other. You may fix a part to the surface side of a formwork. Further, the connecting member may be one having no flexibility, and in that case, a hook-like portion may be provided at the tip and the hook may be hooked on a required mesh of the fixed mesh.

Further, as explained in the above embodiment,
The step of filling the granular filler in the gap formed between the stacked stones and the mold may be performed while the stones are being stacked, or may be performed after the stones are held in a fixed state by a fixed net. . The size of the fixed net is set, for example, to a size of 50 cm square or a 1 m square according to the size of the stone. The fixed net may be a wire net.

[0034]

The present invention has the following excellent effects. From stacking stones along the back of the formwork,
As shown in FIG. 3, the finished surface 23 of the masonry portion is naturally finished as a flat surface or a curved surface. Therefore, even an unskilled person can easily form a masonry finished surface that looks good.

Further, since the masonry portion is held on the formwork by the fixed net, the piled stones are stably fixed at a predetermined position. Therefore, it becomes possible to compact the concrete placed between the formwork with a vibrator, and the concrete can be densely filled in the gaps in the masonry portion excluding the portion filled with the filler, and as in the conventional case, There is no fear of creating voids in the gap. Therefore, as in the past, it is difficult to invade water into the masonry wall, avoiding the risk of stone falling off due to concrete peeling, and constructing a structurally highly stable masonry wall. You can

In the conventional method, stones had to be stacked one by one at intervals of several days in order to wait for the setting concrete to harden. According to the invention, since there is no risk of the stones collapsing, it is possible to stack stones up to the required height of the formwork. Therefore, it is possible to pour concrete between the formwork at one time over the entire part where the stones are piled up, and the concrete pouring work can be made extremely efficient as compared with the conventional one, and the construction period can be greatly shortened. It will be possible to reduce the construction cost.
