摘要： PROBLEM TO BE SOLVED: To employ a gasket for joint sealing thereby to eliminate the need for backup materials required to place secondary seals and omit works related to the secondary seals thereby to simplify processes and reduce costs. SOLUTION: A gasket 15 consisting of a mainbody 15a at least as wide as a joint and long in one direction and a shed 15b constituting flanges 15c integrally formed on the single face of the mainbody 15a with both sides extending from the side faces of the mainbody is used as a joint material. Backing treatment is given to the gasket mainbody 15a, which is fitted to the back of the joint 14 for decorative panels 11 set at the bottom of a form. The flanges 15c are abutted to the backs of the decorative panels 11 on both sides of the joint. Secondary seals 16, 17 are applied to the abutted portions by using optional means to prevent the leakage of concrete slag with the gasket 15.

摘要： PROBLEM TO BE SOLVED: To maintain water proofing performance and prevent cracking in a light cellular concrete plate corresponding to a joint around decorative plates due to temperature change and wind pressure by laminating the light cellular concrete plate and a plurality of large decorative plates to be relatively movable in a plane direction via a water-proof layer. SOLUTION: For a light cellular concrete (ALC) combined panel A, a plurality of large decorative plates 1 formed from large ceramic plates such as tiles having an area of 0.1 m or more each on the surface side are laminated on a ALC plate 2 via a water-proof layer 3 so that the ALC plate 2 and the large decorative plates 1 are relatively movable in a plane direction with the water- proof layer 3. The water-proof layer 3 includes a water-proof material layer 4 such as a water-proof paint layer showing water proofing performance and a stress relaxing layer 5 such as a sponge capable of relatively moving the large decorative plates 1 and the ALC plate 2 in the plane direction. Latching pawls 18, 19 for a stopper fitting 6 are latched to latched holes 1a in the large decorative plates 1 and an anchor portion 9 of the stopper fitting 6 is locked to a fixing groove 7 formed in the ALC plate 2 for connection.

摘要： PROBLEM TO BE SOLVED: To prevent an anchor auxiliary member from being loosened from concrete by providing a projection piece orthogonally projected outward and formed to have a wedge shape at a forward end on the end of each wall panel erected in parallel, and integrally providing a seat plate with a loose hole between the wall panels. SOLUTION: The ends of wall panels 4e arranged in parallel are respectively provided with wedge form projection pieces 4c orthogonally projecting externally and forming to have wide breadth at forward ends 4d. A seat plate 4b with a loose hole 4a is integrally provided between the wall panels 4e laid in parallel, thereby forming an anchor auxiliary member 4 having spring elasticity. At the time of construction, an anchor bolt is erected on a decorative panel and the loose hole 4a of the anchor auxiliary member 4 is externally coupled to the end of the anchor bolt. Thereafter, a washer is laid between a nut and the seat plate 4b and the nut is screwed to the threaded part of the anchor bolt. In addition, backing concrete is placed on the reverse side of the decorative panel for burying the anchor auxiliary member 4. Thus, the anchor auxiliary member 4 can be prevented from being loosened from the backing concrete.

摘要： PROBLEM TO BE SOLVED: To easily and accurately center an anchor bolt and displace it in accordance with the movement of back-filling concrete when it gets hard and shrinks by providing deformable projections protruding inward at a plurality of positions of the periphery of the hole for an anchor bolt to be embedded in back-filling concrete for a building face panel. SOLUTION: Projections 3 are formed at every equal distance at the periphery of a bolt hole 4, in a stainless steel anchor 1 to be embedded in back-filling concrete for a building face panel. The projections 3 are deformably protruded from at least three positions of the periphery of the bolt hole 4 to the inside of the hole 4 and the protruded length H is decided in accordance with the movement difference and the following-up property against the displacement of the face panel and the back-filling concrete. When the front ends of the projections 3 at the periphery of the bolt hole 4 come into contact with the anchor bolt due to the displacement of the anchor resulting from the solidification and shrinkage of the back-filling concrete, the projections 3 are deformed to absorb the shrink stress. Accordingly, the clearance between the front ends of the projections 3 and the anchor bolt can be sufficiently made small and hence, the anchor 1 can be favorably centered.

摘要： PROBLEM TO BE SOLVED: To prevent the cracking or breakage of large decorative plates, prevent water permeation, improve workability, hardly stain them with dirt and sustain a beauty by laminating a plurality of large decorative plates with a specified surface area in close contact with a backing precast concrete and filling elastic mortar in their joints. SOLUTION: A plurality of large decorative plates such as large ceramic plates having an area of 0.1 m or more each on the surface side and a width and length of 300 mm or more are laminated in close contact with the surface of a backing precast concrete plate 2 while leaving their joints 3 at preset spaces and elastic mortar 4 is filled in the joints 3. The backing precast concrete plate 2 is preferably formed as alight-weight cellular concrete plate. The elastic mortar 4 is preferably formed by mixing acryl, styrene or ethylene vinyl acetate based latex in a range of 10-50 wt.% in polymer amount to a total weight of cement and sand into cement such as ordinary Portland cement and fine sand having a grain size of 1.2 mm or less.

摘要： PURPOSE:To mitigate the stress generated between a hook claw and an anchor section and improve durability by forming a stress mitigating shape section on an arm section, and hooking the hook claw provided with the anchor section fixed to an outer wall on the hook groove of an external facing board. CONSTITUTION:A hook claw 3 is inserted into the hook groove 7 of an external facing board 5, and the tip of the hook claw 3 is brought into contact with the deepest position of the hook groove 7. When a tensile load is applied to a clamp metal 25, the cross section receiving the shearing force secures the maximum area from the deepest position of the hook groove 7 to the surface of the external facing board 5. When a repeated load by the wind pressure is applied to the external facing board 5 in this hooked state, for example, stress is generated between a rigidly fixed anchor section 1 and the hook claw 3. The stress is dispersed and mitigated by a stress mitigating shape section 23. The stress applied between the anchor section 1 and the hook claw 3 is reduced, and the durability of the clamp metal 25 can be improved.

摘要： PROBLEM TO BE SOLVED: To provide an anchor metal fitting for a decorative panel, by which firm bonding to backing concrete is obtained. SOLUTION: In the anchor metal fitting 4, an anchor body section 5 is formed in a grooved shape and holding pawls 6a, 6b are fitted, the holding pawls 6a, 6b are held into grooves in parallel in the rear of the decorative panel under the resiliency of the main body section 5, and the two-leg plates 5b, 5c of the groove-shaped body section 5 are constrained so as not to be separated by a constraining member 13. A projecting piece 14 having a fan-shaped wedge shape is formed to the side end of the web 5a of the groove-shaped main body section 5 at that time. Accordingly, the firm bonding of the anchor metal fitting 4 to backing concrete is obtained.
