2. Description of the Related Art A cloth frame water laying frame device of this type, which is already known, for example, is disclosed in Japanese Patent Publication No. 1-292828, is a flat rectangular support frame in which four sides are surrounded by side plates. A cloth form frame is stretched, settled and settled at a predetermined position on the water bottom, and when the concrete poured into the cloth form frame reaches the required hardening state, only the support frame is lifted and removed. .

Since the side plate has the steel plates stretched over the side surfaces of the upper and lower steel pipes connected to each other above and below the truss member, the support frame surrounded by the steel plates is
Although it is strong in strength, in order to make it heavier by that amount, the suspension crane used for this must naturally be of a large size corresponding to it.
Further, if sand mud adheres to or is clogged with the truss member or the portion between the upper and lower steel pipes of the side plate, or if the steel pipe is filled with water, the suspended weight is added, so that as a suspension crane It is necessary to make it more powerful. One of the objects of the present invention is, as described above, a structure in which sand or mud does not adhere or become clogged, and water does not enter the inside, whereby the suspension crane is smaller and smaller in capacity than conventional ones. It's about getting things done.

Further, the above-mentioned supporting frame has marking rods projecting above the water at its four corners. For example, in order to construct a scour preventive concrete floor at the bottom of the water below the jetty, It is necessary to insert one end of the support frame into the lower part of the pier so that the bottom of the support settles down. Another object of the present invention is not to provide such a marking rod, and to make it possible to easily insert one end portion of the support frame below the pier or the like.

Furthermore, since the support frame is a flat rectangular one in which four sides are surrounded by side plates, the cloth form frame fitted and stretched inside the support frame cannot be brought into continuous contact with the shore wall. Is. That is, since the side plate on one side inevitably intervenes between the cloth formwork and the quay wall surface, when the support frame is lifted up after placing concrete, there is a gap between the cloth formwork and the shore wall surface. You can Therefore, it has been necessary to separately fill the void as necessary. Still another object of the present invention is to make it possible to bring them into continuous contact with each other without forming a gap between the cloth formwork and the quay wall surface.

In this case, the support frame A is, as is apparent from the above, the large-diameter steel pipes 1, 1 on the left and right sides and the tip side.
2. The medium-diameter steel pipe 3 and the small-diameter steel pipe 4 are simply assembled vertically and horizontally, and each steel pipe is a sealed hollow steel pipe by closing both end openings with end plates 6, 7 and 8. Since sand mud adheres to or is clogged with the assembled voids and water etc. does not infiltrate and fill each steel pipe, it is not weighted, and on the contrary, the above-mentioned sealing gives buoyancy and makes it lighter, so the capacity of the lifting crane is relatively small. Things are enough. Also, the support frame A
A series of hoisting work can be smoothly and safely carried out without causing an unbalanced load on the support frame A when hoisting the machine and causing a danger or breaking.

As is apparent from the above description,
According to the present invention, the following effects can be obtained. The support frame is simply composed of large-diameter steel pipe, medium-diameter steel pipe and small-diameter steel pipe vertically and horizontally, and each steel pipe is made into a sealed hollow steel pipe by closing the openings at both ends. Is not attached or clogged, water is infiltrated into each steel pipe, and it is not weighted.On the contrary, since the above sealing gives buoyancy and makes it lighter, the capacity of the lifting crane is relatively small. Is enough. Also, when lifting the support frame, an unbalanced load is applied to the support frame, which is dangerous,
A series of lifting operations can be carried out smoothly and safely without any breakage.

Since the supporting frame has a U-shaped base frame formed of a large-diameter steel pipe and is open at the base end side, the end face of the cloth form frame can be brought into continuous contact with the shore wall. That is,
Like the conventional one, the side plate of the support frame is interposed between the cloth formwork and the quay wall surface, and when the support frame is lifted up, a gap is created between the cloth formwork and the shore wall surface. There is no need for a separate work to fill the gap.
