摘要： PROBLEM TO BE SOLVED: To obtain a composite light-weight floor slab having excellent structural performance, fire-resistive performance and sound-insulating performance in spite of light weight by forming a mortar layer on the underside of a reinforcing truss, a light-weight concrete layer on a top face and a foamed mortar layer in an intermediate section. SOLUTION: Reinforcing trusses 20, 20 consisting of top chord bars 22, 22, lower chord bars 24, 24 and lattice bars 26, 26 are installed into forms, and mortar is placed and a mortar layer 12 is formed. Foamed mortar having specific gravity of approximately 0.5 is poured and cured immediately after the placing of mortar, and a foamed mortar layer 16 is formed. The foamed mortar layer 16 is cured, light-weight concrete is placed and a light-weight concrete layer 14 is formed, and the composite light-weight floor slab 10A is manufactured. The composite light-weight floor slab 10A has structural performance, fire-resistive performance, sound-insulating performance, etc., equivalent to or higher than that of the conventional reinforced concrete floor slab in spite of light weight. A beam is laid on the floor slab 10A, concrete is placed in a joint section, and adjacent floor slabs 10A and beams are integrated at the time of the execution of works.

摘要： PURPOSE:To enhance work efficiency by setting a transverse cross section shape to a hollow cross section shape in a long beam receiving member having a top and a bottom and installing slidingly a transfer board having a circular hole on the bottom. CONSTITUTION:A load receiving beam 1 is formed with a long receiving beam member having a hollow part 7 by a top 2, a bottom 3 and both sides 4 and 5 while a board-shaped stopper 10 is installed in the longitudinal direction of a long hole of the bottom on both sides and the both sides of the top 3 is folded, thereby forming a groove 11. Then, a transfer board 6 having a circular hole is fitted into the groove 11 and forced to move slindingly between the board- shaped stoppers 10. This construction makes it possible to comply with readily any change, even if it is made about the spacing between both sided vertical levers of a vertical frame of timbering which fits in the circular hole and the long hole.

摘要： PURPOSE:To erect one side scaffolds, by fixing a base bracket on the wall of a veranda and providing tread plates and handrails on the vertical rods fitted to a receiving member and spanning support members or the like to prevent from falling down, on the vertical rods from support rods. CONSTITUTION:The upper part of wall in a veranda or the like is held from both right and left sides to contact the wall face by wall face plates of the vertical support member of a base bracket body 1 and the vertical holding member of a clamping member 2. Next, a horizontal member and a horizontal fitting member are fitted to each other and a female screw with handle is fastened to a male screw bar protruded from a pierced hole. Then, the wall face is held from both right and left sides by a vertical support member and a vertical holding member by fastening with the handle to fix the base bracket. Subsequently, the base bracket fixed at the end of wall face like a veranda is fixed by inserting the vertical rod 3. And further, the vertical rod 3 is erected and scaffold plates 5 are fitted in accordance with the stories of the building. Then a support member 19 for preventing from falling down is erected and fixed between the vertical rod 3 and the support rod 14.

摘要： PURPOSE:To provide a fold type moving work bench, which does not require large space for storage by enabling the bench to move in an easily folded manner even in a narrow space, and to be stored in a stacked manner. CONSTITUTION:A fold type moving work bench has an upper-stage handrail frame part 1, an intermediate-stage scaffold plate support part 2, and a lower- stage caster part 3, and all of them can be freely and respectively attachable/ detachable. A pair of frame bodies of the handrail frame part 1 has fixed lateral rods 6 and rotating lateral rods 5, which are rotated to be attached to or detached from the fixed lateral rods 6. The scaffold plate support part 2 is linked with vertical rods 11 at both end parts so that the support part can be rotated freely, and has fold type lateral rods 13, which are folded into flat M-shape, with hinges 14 provided on the center in the longitudinal direction, and scaffold plates 24 can be put on the support part attachable/detachable. The caster part 3 comprises two frame bodies consisting of vertical rods 26 and lateral rods 27 having a caster 29 in the lower part.
