摘要： PROBLEM TO BE SOLVED: To provide an expansion form which ensures enhancement of the economy by arranging so that it can be collected and reused to another place as a hollow foundation inner form or sheathing form in a deep foundation. SOLUTION: An expansion form is embodied as a cylindrical form 14 with the periphery divided in the circumferential direction, and the form 14 is arranged expandable in the radial direction from the center. The cylindrical concrete form 14 is exfoliated from the concrete by contracting it in the radial direction, and thereby collecting of the form and its reuse to another place are made practicable. Various expanding/contracting structures of the concrete form are considerable, but one preferred is that coupling is generated by an arm 13 fitted with an expansion joint interposed between the cylindrical form 14 and a shaft located in the center. It is also preferable that a suspension frame 11 is provided in the neighborhood of the joint of the arm 13.

摘要： PROBLEM TO BE SOLVED: To facilitate a reinforcing work of an opening, by fitting a drawing-out tool which has a specified length in the depth and a width reduced from the upper side toward the lower side, at appropriate side faces of a form in which the four side plates are decomposably combined. SOLUTION: Four plates 5, 6 are assembled to be decomposable at the corners and shape a form 4. A drawing-out tool 1 which has a specified length A in the depth and a width W reduced from the upper side toward the lower side is fitted to an appropriate outside face of longer side plates 5, 6 of the form 4 with a bolt 3. This form 4 is nailed at a specified position on a concrete form P and concrete is placed to construct a concrete floor C. Then the form 4 is removed to form an opening on the concrete floor C. And an insertion reinforcing metal is pushed in the narrow groove at the lowermost part in a cavity formed at the side face of the opening. Thereafter, a plywood form or the like is arranged to contact the lower face of the opening and concrete is replenished in the opening to complete a repair work.

摘要： PURPOSE: To provide guardrail support fixing method in which fixation is light weight, water resistant and sturdy, and easy, and a paper-made elliptic pipe form inner frame for concrete foundation fixing the support pole. CONSTITUTION: A waterproof treated, elliptic pipe form, paper-made inner frame for forming an elliptic hole 31 is placed upright within a recess hole formed along edge of a road. Raw concrete is then injected into gap between inner face and outer face of the recess hole. After setting of the raw concrete, the inner frame is removed, so that a concrete foundation 30 having a section elliptic hole 31 for inserting a support pole 11 within the recess hole is formed. A support pole 11 is inserted in the hole 31 of concrete foundation 31. Additional raw concrete is filled in gap between the support pole 11 and the inner face of the hole 11, so that the support pole 11 is fixed.

摘要： PURPOSE:To make efficient construction work by providing a mold releasing member having high bearing strength reinforced with honeycomb cores or hollow cylinders to a specific position in the case through-holes or recesses, etc., are provided to a concrete structure, and removing the mold releasing member after the solidification of concrete. CONSTITUTION:In case that through-holes or recesses are provided to a concrete structure such as a wall, floor, etc., a mold releasing member 3 with the surface coated with polyethylene resin, etc., and reinforced with hollow bodies such as honeycomb cores, etc., is provided to a specific position. The mold releasing member 3 can be mounted directly to a form or mounted through a temporary member 2. Water, etc. can be injected in the form to increase compressed strength. Concrete is placed in the form, and the mold releasing member 3 and temporary member are eliminated after the solidification. According to the constitution, construction work can be carried out efficiently.

摘要： PURPOSE:To dispense with the ensuring of a clearance, use a sleeve with a necessary minimum diameter, solve a limitation on structure, simplify piping work and repairing work as much as possible, and realize overall cost reduction. CONSTITUTION:Blind plug 7 are fitted to the other end parts of metal pipes of an inner pipe 4 and an outer pipe 5 the end parts of which are mutually fitted in such a manner as to be capable of sliding. The blind plug 7 has a bolt hole, and the cap 7 is fixed to the inside of a beam form 10 through the bolt hole by a bolt 13, whereby the metal pipes are arranged as a sleeve in the form 10, and after concrete placing and form removal, the metal pipes are used as an actual pipe for duct.
