摘要： PURPOSE:To easily and firmly attach a building plate material by providing an elastic bed material attaching part having a U-shaped cross section with a locking piece through a standing up piece, and locking a locking protrusive piece formed at the end of the building plate material to the locking piece. CONSTITUTION:An end part fixture which is formed of an elastic U-shaped attaching piece 4 and a locking piece 2 vertically provided at the end of the piece 4 through a standing up piece 1a is provided. A connecting fixture 6 which is formed of an attaching piece 11 severally provided with elastic U-shaped parts on its upper and lower sides, a standing up piece 7 protrusively provided at the middle of the piece 11, and a locking piece 9a having a locking part 8 vertically provided at the end of the piece 7 are provided. The backs of both the ends of a building plate material 15 are severally provided with locking protrusive pieces 16, and its front face is provided with a protrusive piece 18 and a convex part 20 through grooves 17, 19. After fixing the fixture 1 to a bed material the locking piece 2 is engagedly inserted in the groove 17, and after attaching the fixture 6 to the protrusive piece 16 through the locking piece 9a, the fixture 6 is fixed to the bed material. Thus the unlevelness of the bed material can be regulated, and the prevention of the damage of a plate material and the improvement of an outside appearance become possible.

摘要： PURPOSE:To form a flash setting agent for cement having excellent setting property not only at an usual temp. but at a low temp. by compounding alkali metal aluminate, alkali metal carbonate, calcium aluminate and aluminum sulfate. CONSTITUTION:The flash setting agent for cement is formed from following components (a)-(d). 10-25wt.% alkali metal aluminate (a), 5-25wt.% alkali metal carbonate (b), 50-70wt.% calcium aluminate (c) and 5-13.8wt.% aluminum sulfate. A part of the calcium aluminate can be replaced by quicklime and(or) slaked lime in not more than about 15wt.%. Quicklime and slaked lime are somewhat inferior to calcium aluminate in respect of exhibiting strength in cement material but, since they are cheaper than calcium aluminate, and especially quicklime reacts quickly with water even at a low temp. and supplies calcium ion required at the initial stage of hydration reaction while generating heat, they are preferably used when the flash setting agent above-mentioned is used at a low temp.
