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 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 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 make the most of high productivity of an immediate form removal method and to dispense with a process of surface finishing of concrete after forming. CONSTITUTION:A double form composed of a main form 1 giving a mechanical strength as a form mainly and of an internal auxiliary form 2 fitted on the inside of the main form 1 and constituted of a sufficiently thin plate material is provided. Concrete 3a of a very small slump is placed in this double form and filled up therein by applying pressure and vibration thereto and a semi- finished product 3b covered with the internal auxiliary form 2 is removed from the main form before the concrete is set. After the semi-finished product 3b is cured properly, the internal auxiliary form is removed.

摘要： PURPOSE:To carry out an easy or automatic removing operation of stain such as cement paste leaked out on the front surface side of stone materials or the like. CONSTITUTION:In a joint layout process, a large number of stone materials 3 are arranged on a form bed 1 for manufacturing a PC (precast concrete) panel under the condition that the front surface side of the stone material is faced downwards. At the same time, between the stone materials 3, temporary joint materials 2 are provided so as to position the whole of them and, in the interval parts on the upper surface side of the temporary joint materials 2, ultrasonic shielding members 4 are fittingly installed. Next, in a concrete placing process, concrete C is placed in a form, in which joint layout is completed, Next, in a demolding process, by demolding after the curing of the concrete C and removing the temporary joint materials 2, a PC panel 5, onto the under side of the concrete of which the stone materials 3 and the ultrasonic shielding member 4 are bonded, is obtained. Further, in a washing process, the stone material arranged surface side of the PC panel 5 is ultrasonically washed by being immersed in the washing solution in an ultrasonically washing tank. Furthermore, in a joint finishing process, after the washed PC panel is dried, finishing joint materials 6 are mounted to the joint parts of the stone materials 3.
