摘要： PURPOSE: To simplify a positioning and installation work of a form and eliminate the need for a skilled work and omit a form support work and save manpower and shorten a construction period and execute safety work without a high elevation work and further increase the durability of a concrete structure by protecting the surface of the concrete structure with a PC form. CONSTITUTION: In a PC(precast concrete) form construction method where a PC form 12 is assembled as a form for a concrete structure and concrete is placed and this PC form is left over even after the concrete placement, a support steel material 13 for the next assembled PC form 12 is installed to the PC form 12. After the form 12 with the support steel material 13 is installed and concrete 16 is cast, the next assembled PC form 12 is positioned along the projecting support steel material 13. The PC form 12 and the support steel material 13 are fixed with bolts or the like so that concrete may be cast.

摘要： PURPOSE:To correctly perform the construction by inserting reinforcing bars penetrating a formwork box and the pressure supporting wall of the formwork box into a groove, connecting the formwork box to another formwork box inserted previously with tie rods, then placing concrete at the back of the formwork box. CONSTITUTION:Tips of reinforcing bars 6 penetrate the pressure supporting wall 3 between both side plates 4 of a formwork box 2 with a nearly U-shaped cross section, the reinforcing bars 6 are connected to the formwork box 2. Deformed reinforcing bars 8 are protruded from the front and back faces through the pressure supporting wall 3. The formwork box 2 is inserted into a groove 1 and connected to another formwork box 2 inserted previously with tie rods 10. Concrete 13 is placed and hardened at the back of the digging advance direction of the formwork box 2, then crushed stone 17, a cover plate 14, a support section 15 and a guide section 19 are extracted from the groove 1.

摘要： PURPOSE:To eliminate damage to the cross section of top plate by shortening the setting depth of sheathing materials by a method in which a coping stone serving as guide wall in combination is connected to the top of a sheathing material, the inside of the sheathing material is excavated for an underground continuous wall to the lower end of the top plate, and the top plate is constructed on the head. CONSTITUTION:The ground on both sides of a place where an underground continuous wall is to be constructed is improved while mixing it with a hardener, and sheathing materials 8, e.g., H-steel, etc., are vertically set. Concrete for guide wall 6 in an underground continuous wall construction method is placed up to the height of the excavated face of a top plate 2 in such a way as to bury its head. A coping stone 4 serving as guide wall 6 is provided for the head of the material 3 for connecting and underground continuous wall 1 is constructed to the height of the top plate 2 until a given depth is reached inside of the material 3. The ground surrounded by the material 3 is excavated to the lower end of the top plate, and the top plate 2 is constructed on the wall 1. The needs for shoring strut construction can be eliminated during the excavation of top plate portion, and the construction work can thus be economized.

摘要： PURPOSE:To exactly support horizontal forces to be applied by a method in which a bearing wall, a form box, and a reinforcing bag cage are set in a trench, the bearing walls on both ends of the form box are connected with tie rods, concrete is placed into the form box, and cover plates are set in front of the excavating direction. CONSTITUTION:A given depth of trench 1 is excavated in the ground, and a form box 2 consisting of a bearing wall 3 and side plates 4 and reinforcing bars 6 are integrally penetrated into the trench 1. The form box 2 is fixed with tie rods 10 through the wall 3 by using nuts 11. Concrete 13 is placed in the rare part of the excavating direction of the box 2, and cover plates 14 are set in front of the excavating direction of the box 2 to close the trench 1. The ground in front is excavated. The underground wall can thus be exactly constructed without causing the displacement of the form box because of support by the tie-rods and can withstand the horizontal forces such as soil pressure, etc.
摘要翻译：目的：为了通过将轴承壁，形式箱和加强袋保持架设置在沟槽中的方法来精确地支撑水平力，将成型箱两端的支承壁与拉杆连接，混凝土被放置在形式箱中，并且盖板被设置在挖掘方向的前面。构成：在地面上挖出一定深度的沟槽1，并将由轴承壁3和侧板4以及钢筋6构成的成形盒2整体地贯穿到槽1中。成型箱2用拉杆通过使用螺母11，通过壁3将混凝土13放置在箱体2的挖掘方向的罕见部分中，并且将盖板14设置在箱体2的挖掘方向前方以封闭沟槽1。前面的地面被挖掘。因此，地下墙可以精确地构造，而不会由于拉杆的支撑而导致成型箱的位移，并能够承受水平力如土压力等。

摘要： PURPOSE:To rationalize building and shorten a term of works through restraining of only the one side, by a method wherein a well foundation is constructed in a way that L-continuous walls are interconnected to a always extend in the same direction, and an interlocking plate is used for interconnection of wall bodies. CONSTITUTION:A first wall body 2a is built in a way that, after holes are bored at intervals of one piece, an L-oblong hole is formed. After a bottom is processed with slime, a reinforced cage 4 and a rocking plate are built, and concrete is placed. After a second wall body is excavated according to similar precedures described above, the rocking plate 8 is pulled off. After a partition plate 5 and overhanging bars for connection are cleaned, slime processing is applied, the reinforced cage 4, to which the partition plate 5 is attached, are built, the rocking plate is built, concrete is placed, and the followings are carried out by the same precedures to build a well foundation. This enables rationalization of building and shortening of a term of works.

摘要： PURPOSE:To obtain an artificial bottom slab integrated with the foot-protected portion by a method in which the foot-protected portion is formed by pouring cement mortar through a pipe buried in the continuous underground wall, and cement mortar is placed to the area surrounded by the underground wall through a bored hole. CONSTITUTION:Cement mortar, etc., is poured through a pipe 6 buried in a continuous underground wall 5 from the ground's surface and jetted to just below the wall 5 to form a foot-protected portion 7. Boring is then made in the area surrounded by the wall 5, and cement mortar, etc., is injected through the bore hole 8 to form a bottom slab little by little to much the same level as the foot- protected portion 7. The boring process and the cement mortar pouring process are alternately repeated to widen the area of the bottom slab to obtain an artificial bottom slab 10 integrated with the foot-protected portion 7. Afterwards, a top slab 11 is placed on the underground wall 5 and then a superstructure 12 such as bridge, etc., is constructed on the top slab 11.

摘要： PURPOSE:To enhance the close contact ability and to prevent cracks by building a steel cell in which stud dowels are arranged on the lower inner side surface of a horizontal opening, on the lower structure of a reinforced concrete section, by placing core concrete from the opening, and by applying a tension to a PC steel member. CONSTITUTION:A steel cell 5 is built on the lower structure 13 of reinforced concrete section, reinforcement 14 is arranged along stud dowels 11 using a horizontal opening 9 as an access opening, and then PC steel members 15 is arranged. Further, reinforcement 14' in the reinforced concrete section in the lower structure 13 is connected to reinforcement 14, and the PC steel members 15 are connected to PC steel members 15' in the lower structure 13 through the intermediary of couplers 16. Thereafter, core concrete 17 is placed through the opening 9 after a fixing plate 21 is set below a horizontal plate 10, and after the hardening of the concrete, the PC steel members 15 are applied with a tension so as to give a prestress to the core concrete 17. Further, a plate 18 is laid on the horizontal plate 10 so as to block the opening 9, and then the horizontal plate 10 and the plate 18 are fixed by using bolts 20. Further, a gap at the top of the core concrete section 17 is filled therein with a grout material 19.
