摘要： PURPOSE:To facilitate the manufacturing and improve the water sealing performance by a method wherein for manufacturing a PC panel, when concrete has not been cured, swelling waterproof agent including bentonite, as major component, is scattered over the surface of the concrete so as to be uniformly applied thereto. CONSTITUTION:For manufacturing a waterproof type driving PC panel form 10, concrete C is cast into a molding form 12, following which in an initial stage of hydration reaction wherein the concrete C becomes cured to some extent, a swelling waterproof agent 14 including bentonite, as major component, is scattered over the surface of the concrete so as to be uniformly applied thereto by means of a trowel or the like. Next, after the concrete is cured, it is removed from the form 12. Further, when the waterproof agent 14 can not be applied to the surface of the PC panel 10, a sheet impregnated with the agent 14 is bonded to the surface of the form 12 and thereafter concrete is placed into the form 12. And the PC panel can be used as a form when an underground wall or the like is constructed. Thus, waterproof agent can be made integral to the PC panel easily, and waterproof is achieved by the use of a three- layered structure comprising PC panel, waterproof agent, and cast-in-place concrete.

摘要： PURPOSE:To improve outer appearance and durability by absorbing relative displacement in the surface direction caused by differential thermal expansion between an external wall base material and an external surface material in simple installation structure. CONSTITUTION:This external wall material is furnished with an external wall base material 2, an external surface material 4 arranged on the outdoor side of this external wall base material 2, a protruded part 5 provided on the back surface of this external surface material 4, an installation member 3 provided on the outdoor side of the external wall base material 2 and having an opening part 6 the diameter of which is larger than that of the projected part 5 and coming-out stop members 7, 8 provided on the projected part 5 inserted into the opening part 6 of this installation member 3. Consequently, relative displacement in the surface inside direction caused by differential thermal expansion between the external wall base material 2 and the external surface material 4 is absorbed in a clearance (s) between the protruded part 5 and the opening part 6 of the installation member 3, and it is possible to improve outer appearance and durability.

摘要： PURPOSE:To provide a state, wherein water can be absorbed to effect swelling, only after being in contact with a cast concrete without being unnecessarily swelled even if being in contact with water. CONSTITUTION:When a PC panel driving form 16 for constituting an inside form of an underground wall is manufactured, during the time at which cast concrete C is not cured, a swelling waterproof material 12 containing bentonite is applied to the surface of the concrete. And thereafter, emulsion of polymer which is soluble in alkali but insoluble in water is applied to the surface of the agent 12 and cured to form a waterproof film 14.

摘要： PURPOSE:To protect a concrete surface in removal from a form and remarkably improve an integrity of a surface finishing material through a woven or nonwoven fabric by a method wherein before a concrete is placed, the woven or nonwoven fabric is previously attached to a concrete-contact surface of the form so as to be integrated in the concrete surface at the time of removal. CONSTITUTION:Before a concrate 14 is placed inside a form 12, a woven (or nonwoven) fabric 16 is attached to an inner surface 12a of the form 12. Immediately after the concrete 14 is placed inside the woven fabric 16, a vibrating rod 2U is inserted into the center of the form 12 to pressurize and vibrate the concrete 14, and the concrete 14 is immediately removed from the form. At the time of removal of the concrete 14 from the form, the woven fabric 16 adheres to the surface of the concrete 14 to prevent the surface of the concrete 14 from being directly rubbed with the form surface 12a. Furthermore, an integrity of a finishing material is remarkably improved through the woven fabric 16.

摘要： PURPOSE:To ensure bending strength in beams effectively by reducing height difference between beam lower end main reinforcing bars and joint reinforcing bars to a column for forming lapped joints and, at the same time, to obtain such a PC beam form as bending strength of the beams can be advantaged by reducing height difference between them against the joint reinforcing bars even if the beams are arranged at right angles. CONSTITUTION:A PC beam form 10 is so precasted that it has a U-shaped section, and a plurality of beam lower end main reinforcing bars 26 are buried in the bottom 10a along the extended direction of the beam from 10. First grooves 30 positioned at sides of the beam lower end main reinforcing bars 26 and for arranging the ends of reinforcing bars 14a of joint reinforcing bars 14 are formed in the bottom 10a into which the beam lower end main reinforcing bars 26 are buried. In the case beams are constructed, the ends of the reinforcing bars 14 on the lower sides of the joint reinforcing bars 14 are arranged to the first grooves 30 in a state to mount the end of the PC beam form 10 on the upper end face of a PC column form 20. Under such a state, concrete is placed in the PC beam form 10 to form lapped joints of the reinforcing bars 14a and beam lower end main reinforcing bars 26 horizontally.

摘要： PURPOSE:To carry out the immediate removal of a PC product by a method wherein water is previously absorbed into an absorbent polymer which does not gel but keeps its independent form even when absorbing water, and the polymer absorbing water is mixed with a cement, an aggregate, and an admix ture, and the mixture is placed in a form and vibrated. CONSTITUTION:A molding form 10 consists of an inner form 14 and an outer form 16 which are coaxially disposed. A concrete 40 is placed into a space part 18 between the both forms 14, 16. Water is previously absorbed into a special water absorbent polymer which does not gel but keeps its independent form even when absorbing water. The concrete 40 is composed of the mixture of the polymer absorbing water, a cement, an aggregate, and an admixture. The placed concrete 40 is vibrated by a vibrator 22 mounted on the outer form 16. In this manner, water in the water absorbent polymer is exuded to make the concrete warkable. The concrete 40 is contacted and pressurized by a pressurizer 24, therefore being acceleratedly set. Therefore, the concrete 40 has a sufficient removal strength and can be immediately removed as a PC product.

摘要： PURPOSE:To achieve wt. reduction and to enhance productivity by forming a PC curtain wall panel from a PC base panel integrally molded from concrete in such a state that ribs are arranged on the rear surface of a surface layer panel in a lattice shape to be integrally molded by concrete and casting forms composed of a lightweight refractory heat insulating material integrally provided so as to be left in the lattice-shaped ribs. CONSTITUTION:A PC curtain wall panel 2 consists of a PC base panel 8 wherein lattice-shaped thin-walled ribs 6 are integrally provided to the rear of a rectangular thin-walled surface layer panel 4 and casting forms 10 composed of a lightweight refractory heat insulating material integrally provided so as to be left in the lattice-shaped thin-walled ribs 6. The PC base panel 8 is integrally molded from concrete and, as the lightweight refractory heat insulating material constituting the casting forms 10, mortar using inorg. or org. foam or lightweight aggregate such as pearlite is used. The casting forms 10 are left to function as refractory heat insulating layers. Fasteners 16 and hanging insert metal fittings 18 are provided to the lattice-shaped thin-walled ribs 6.
