摘要： PROBLEM TO BE SOLVED: To provide a scaffold-cum-sound absorption system having a good effect of reducing noise generated from vehicles running on a lower road and an upper road on the back side of an under-girder of an elevated road. SOLUTION: Small beams C such as a H-shape steel suspended on the back side of the elevated road or the like are installed at spaces substantially horizontally. Plural metallic louvers 2 are substantially parallelly disposed at small spaces between them, and bolted to the lower side of a lower flange of the small beam. A sound absorption material 8 is placed on the metallic louvers, and the top face thereof is held at the level equal to the top face of an upper flange of the small beam. A metallic corrugated plate 9 is laid as a corridor member on the top face of the upper flange of the small beam, and the intersecting part of the metallic corrugated plate and the small beam is bolted. The metallic louvers have sound absorption holes 2b on the whole surfaces thereof.

摘要： PROBLEM TO BE SOLVED: To reduce noises from a car, etc., by hanging down beams on the rear side approximately horizontally at intervals, arranging a plurality of louvers made of steel in approximately parallel and fixing the louvers on the flange underside sides on the lower sides of the beams by bolts through spacers. SOLUTION: The sound-absorbing system is constituted by laying sound-absorbing materials 8 on a beam (c) suspended on the under-girder rear side of a viaduct in the horizontal direction together with a corridor material. A louver 1 made of steel is fixed on the underside side of the lower-side flange 2 of the beam (c) by bolts 4 through a spacer 3. The height of the spacer 3 is adjusted in response to effective thickness for reducting noises from a road in the sound-absorbing materials 8. Consequently, the top face of the sound-absorbing materials 8 is kept at the same level or less as the top face of the upper-side flange 10 of the beam (c), and a corrugated plate 9 made of steel can be installed directly onto the top face of the flange 10. Accordingly, stability in strength as the scaffold for a corridor is improved, the barrier properties of sound waves from the upper and lower sections of the viaduct, etc., are ensured, and sound-absorbing performance is displayed and noises from the road can be reduced.

摘要： PURPOSE:To mount a hanger metal fixture suspending a ceiling, service pipes, etc., under a floor slab firmly. CONSTITUTION:Arms 15 are respectively mounted inward on both sides of a metal fixture body 12 of a hanger metal fixture 11 so that they are capable of turning. The arms 15 have hook sections 15a on the upper ends of them. The arms 15 are energized inward with torsion springs 14. A hole 12e is bored in the bottom plate 12a of the metal fixture body 12, and a nut 13 is fixed thereto. A hanger bolt 18 is screwed to the nut 13. When the hanger metal fixture 11 is mounted on the bottom of a floor slab, in the case the hanger metal fixture is pushed up from a downward position of the bottom of the floor slab, the hook sections 15a on the upper ends of the arms 15 are so contacted that they hold right and left inclined web surfaces on a deck-plate of the bottom of the floor slab between them and are slid to interlock with channels form in the inclined web surfaces. When the hanger bolt is screwed in until the bottom of the deck-plate is strongly pushed up, the hook sections 15a of the arms 15 are strongly cut into the channels, and the hanger metal fixture 11 is firmly fixed to the bottom of the floor slab.

摘要： PURPOSE:To contrive to improve work efficiency by installing a valley-channel cell to a position deviated from the center of the valley formed between two ridge sections to the slope-side of one of the ridge sections, and by planting and welding, at the same time, a headed stud to the foot of the slope of another ridge section. CONSTITUTION:A deck plate 1 having two ridge sections 2 and one valley section 7 is laid over structural steel beams B. A cell 6 and a cell 6' are respectively formed under the ridge sections 2 with cell bottom boards 5 laid respectively thereto. Then a valleychannel cell 2 in box-like section is installed to the valley section 7 on a position deviated from the center of the valley to the slope-side of one of the ridge sections 2. At the foot of the slope of another ridge section 2, a headed stud 9 is planted and the stud is further welded thereto. After this, concrete 20 is placed over the deck plate 1 and a floor is formed therewith. Thereby ducts for floor wiring capable of corresponding to requirements for office automatization at an intelligent building or the like are formed. With the above-mentioned arrangement, execution of work can be simplified and, at the same time, floor strength can be secured.

摘要： PURPOSE:To prevent the inclination, etc. of a housing or its fence by a method in which a fan-shaped sheathing plate is provided at the back of the side-strut of a sheathing structure, and the sheathing plate is inclined or pushed into a trench according to a slope at which the soil and sand of the trench bottom flow during further excavation period and the depth of the excavated trench. CONSTITUTION:Struts 4 connected by a support jack 3 with a guide groove 2 are erected in a trench 1', and one side end of a sheathing plate 5 is fitted into the guide groove 2 of one side of the struts 4 facing each other. And, the guide groove 2 of the other side of the next struts 4 facing each other is fitted with the other end side of the sheathing plate 5 to fabricate a sheathing structure 6. Then, a fan-shaped sheathing plate 8 is provided at the back of the struts 4 facing each other on the side part of the sheathing structure 6. While excavating the trench 1', the sheathing plate 5 and the struts 4 are pushed down by a back hoe and while pushing down the sheathing plate 8 by the back hoe, is inclined along the slope of the bottom of the trench 1' in order to prevent the flow of soil and sand on the outside of the sheathing plate into the side part of the sheathing structure 6.
