摘要： PURPOSE:To automatically absorb or correct the irregularity due to shrinkage or deformation generated in a transfer material by forming the transfer material transferring an uneven pattern to the surface of cast concrete by blow molding so that mutually engaged stepped parts are provided to the mutually adjacent parts of the transfer materials when a plurality of the transfer materials are assembled at the time of use. CONSTITUTION:Since the outer shape of the transfer surface of a transfer material is generally polygonal, a side having a protruding part 2 and a side having a recessed part 3 are provided to the mutually fitted structural part 1 of the polygonal transfer materials. By combining both parts 2, 3, the dimensional irregularity of the transfer materials can be absorbed. Therefore, the transfer materials can be assembled on a wall surface without hindrance and no concrete leaks from the gaps between the transfer materials. A stepped part is constituted only of the recessed part and a separate member may be inserted. Further, when the rear of the transfer material is formed into a concentrically circular bellows structure, flexibility can be provided to that part.

摘要： PURPOSE:To enhance the number of times of repeated use of a transfer material, in the blow molding of the transfer material made of a synthetic resin transferring an uneven pattern to the surface of cast concrete, by bonding a part of a parison forming a hollow body under pressure at the time of clamping and providing a tie bar hole to the pressure-bonded part. CONSTITUTION:A protruding part 13 is provided at a predetermined position within the cavity of molds 10, 11 used in blow molding and a part of a parison is bonded under pressure at the time of clamping. At this time, a projection 14 or slide core for opening a through-hole is provided to the tip of the protruding part 13 and the through-hole 3 is opened to perform molding. When this transfer material is used, the tie bar attached to a form 5 is passed through the through-hole 3. When concrete is injected in the molds, exuded concrete is accumulated in the recessed part of the pressure-bonded part 6. Therefore, no concrete flows in the hollow body and the transfer material can be repeatedly used. Further, bonded concrete is easily removed and can also be recovered to be reutilized.

摘要： PURPOSE:To easily disassemble and separate, as independent parts, a transfer material, a metal material frame, and a connecting hook material assembled in a prescribed process after using them for a required purpose by removing assembling bolts and nuts, and recycle them. CONSTITUTION:A concrete placing transfer material 10 consisting of a thermoplastic resin such as polypropylene is integrated into a metal frame 11, and assembled through a connecting hook material 12. A hook part 12a is fitted to a stepped part 13a to mount the connecting hook material 12, and the transfer material 10 is inserted into the metal frame 11 until its collar part 10d makes contact with the upper edge part of the metal frame 11, and fastened and fixed by a bolt 17 in this state. No mounting metal such as nut is buried in the concrete placing transfer material, which thus can contribute to environment protection in recycling.

摘要： PURPOSE:To obtain a transfer material improved in the releasability from cast concrete, capable of being used repeatedly and capable of imparting diversity to a pattern by molding a transfer material applying unevenness to cast concrete into various polygonal shapes using a synthetic resin and combining a plurality of the molded ones having different polygonal shapes in using. CONSTITUTION:Unit pieces having an octagon 1, a tetragon 2, a trapezoid 3 or the like composed of a synthetic resin are combined to be used. A tie bar attaching hole 4 is pref. provided to a unit piece having a specific polygonal shape, for example, a tetragon 2 among them. Further, the unit pieces are pref. molded as hollow bodies by blow molding. By this constitution, tie bars supporting a form are passed through the holes 4 of tetragonal unit pieces 2 to attach the pieces 2 at predetermined positions. Then, octagonal unit pieces 1, trapezoidal unit pieces 3 or the like are fitted in the gaps between the pieces 2 to be fixed. By combining polygonal unit pieces, a change of patterns such that natural stones are embedded can be obtained.

摘要： PROBLEM TO BE SOLVED: To simplify structure and to make manufacture and execution of work easy by a method wherein channel steels or the like are fixed to both ends of a sheathing plate protecting a side wall of an excavated trench while a reinforcement member is fixed at the center, and vertical frames are formed therewith while the sheathing plates are being heaped up. SOLUTION: Channel steels each having a projected fitting part and a recessed fitting part at its upper and lower part are fixed back to back to both sides of a horizontal stiffness reinforcing member (sheathing plate) 2 made up of a beltlike steel plate or the like by bend-forming, and a reinforcement member 1' made from a channel steel is fixed at the center. The sheathing plates 2 in plural numbers are installed in heaping-up at a side wall of an excavated trench for laying portable water pipes, sewer pipes or the like therein, and thereby a sheathing panel 10 is formed. With the shathing plates 2 heaped up on installation, the projected parts and the recessed parts of the channel steels on both sides are fitted together and a vertical beam 1 is formed thereby while the reinforcement members 1' at the center are connected together to form a vertical beam. Connecting parts of the channel steels are fixed with pins or connecting metal fixtures. The structure of the sheathing plate 2 is simplified while the number of component parts are reduced, making manufacture and transport easy. Thereby, sheathing works can be executed efficiently.

摘要： PURPOSE:To form a natural stone pattern by a method wherein concrete is placed inside a wall-surface form panel, the binder of the panel, and concrete are unified to form a projecting section having a stone mansonry patter and forms for shaping the pattern of the panel is peeled. CONSTITUTION:The insides of the indented sections of forms for forming a concrete pattern are filled with mortar 10 and mortar is solidified, thus shaping composite forms 11. A plurality of the forms 11 are built crosswise through an end-thick material 12 at a desired inclination, thus forming a wall-surface form panel 13. A rear form panel 14 is formed while being oppositely faced to the wall-surface form panel 13, and the form panels 13, 14 are held at a specified interval by a separator 15. Concrete 16 is placed between the form panels 13, 14, and mortar 10 is unified with concrete 16, thus shaping projecting sections 17 having stone mansonry patters. Concrete 16 is solidified, the form panels 13, 14 are peeled, and the surfaces of the projecting sections 17 having the stone mansonry patterns are washed out and treated.

摘要： PROBLEM TO BE SOLVED: To lighten a support jack for earth retaining consisting of a rotational adjusting member having a screw shaft with a screw section on an outer circumference and a female screw screwed to the screw shaft on an inner circumference and a cylindrical body, in which the screw shaft is fitted in a freely forwarding-retreating manner by operating the rotational adjusting member, and to prevent the occurrence of scuffing in a section, etc., between the screw section of the screw shaft and the female screw of the rotational adjusting member. SOLUTION: Each member of the support Jack 1 for earth retaining is composed of the casting of aluminum or an aluminum alloy while the screw section 2 of a screw shaft 3 and the female screw 4 of a rotational adjusting member 6 are formed in different hardness and/or surface properties. For example, either of the screw section 2 or the female screw 4 is cast by a sand mold, another is cast by a mold, difference is formed under heat-treatment conditions after casting, or either is cast of aluminum or the aluminum alloy having the different quality of material. It is preferable that a part of the outer circumferential surface of the rotational adjusting member 6 is formed in a polygonal shape or a plurality of projecting strips 20 or recessed sections 21 are formed.
