Abstract

PROBLEM TO BE SOLVED: To prevent the generation of impact sound from a separator and make the removal of separator unnecessary by attaching a bar-shaped separator made of biodegradation plastics as a row material to a form for concrete build ing frame and embedding and leaving the separators in the concrete form after pouring concrete. SOLUTION: Bar-shaped separators 1 made of biodegradation plastics as a row material are arranged from a form 2 of a wall of building 1 to a form 2 of a wall of building 2 where two buildings are located with a clearance for expansion joint portion 4 between exterior walls. The separator 1 passes through a water stopping plate 5 in a wall form 2 and is fastened to the side surface of both the forms 2, 2 with lateral battens 6 and fasteners 7. After pouring and hardening concrete 3 in the wall forms 2, 2, fastener 7, end lateral battens 6 and form 2 are disassembled, and a separator 1 is embedded and left in concrete 3. The separator 1 gradually absorbs moisture from concrete 3 and is decomposed, thereby eliminating contact portions to concrete 3, so that the generation of impact sound due to thermal shrinkage of the separator 1 disappears and even the removal becomes unnecessary.

About 1, and its installation. Separator-1 is a rod-shaped body made of biodegradable plastics as a raw material. The illustrated example is a case where the biodegradable plastic separator 1 is used for the frame of a building having the expansion joint 4. That is, 2
There is a space between the joints 4 between the outer walls of the buildings of the ridge. Separators -1 are arranged in series from the form 2 of the wall of the building A to the form 2 of the wall of the building B. . Separator-1 is
It penetrates through the water blocking plate 5 in the wall form 2 and is fastened on the side surfaces of the form forms 2 and 2 by the thick side members 6 and the fasteners 7. In the figure, reference numeral 8 denotes a stopper called a P-con, and 9 denotes a fixing hardware. After setting and hardening the concrete 3 in the wall forms 2 and 2, the fasteners 7, the thick ends 6 and the form 2 are dismantled, and the separator 1 is embedded in the concrete 3. To keep. At that time, the part protruding from the skeleton to the indoor side is removed.
