。[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a place used as a truss material for heavy temporary structures such as temporary piers and temporary structures that relax in reverse due to severe repeated loads, vibrations, etc. It concerns construction methods.

あった。``Prior art'' Conventionally, angle iron was often used as the truss material for these heavy temporary structures, but since it sagged due to its own weight, it was prone to shaking when vehicles passed, making it difficult to use. Recently, the above-mentioned turnbuckle place has been increasingly used instead of this, and it is safe because it can be used with proper tension, so there is less shaking, but turnbuckle places are subject to repeated loads, vibrations, etc. continuously for a long period of time. Since the torso was reversed and the tension loosened frequently, it was necessary to perform regular inspections and tightening.

を発生し易い。In other words, in the case of heavy temporary structures such as dump trucks, crane trucks, and other work vehicles entering foundation construction sites that support heavy objects, and temporary piers, the operation of dump trucks and crane trucks that carry 80 degrees above the W& installed cover plate. Since the vertical columns and cross members are subjected to severe repeated loads and vibrations due to the operation of power shovels working directly below the structure, diagonal members are installed between the columns to form a truss and reinforce it. The upright columns, cross members, and place members of the above structure are connected by bolts, welding, or toothed clamps, but in any case, they are subject to the above-mentioned repeated loads and vibrations. Such loads and vibrations are applied to the place material, which applies compressive, tensile, and bending stress to the place material.If a section is used as the place material, it will bend due to plastic deformation and will be difficult to restore, resulting in cracks and separation at the joints at both ends. etc. are likely to occur.

あった（特公昭５８−２３０７号）。To solve this problem, by interposing a turnbuckle in the place material and applying tension in the longitudinal direction, the above-mentioned curvature can be easily restored and the resistance and strength against loads and vibrations can be improved. However, due to vibration due to repeated compression and tension in the longitudinal direction of the place and vertical vibration, the threaded part breaks and the turnbuckle rotates along the thread, causing the turnbuckle to screw into both ends of the turnbuckle. There was a defect in which the threaded part of the place moved to the outside of the turnbuckle, causing the place to relax and curve downward, causing the tension force to become unbearable to the above loads and vibrations (Special Publication No. 58-2307). ).

。``Problems to be solved by the invention'' The present invention aims at a place construction method for heavy temporary structures that can withstand repeated loads and vibrations and has little risk of loosening. ``Means'' The present invention is a heavy temporary structure such as a temporary pier or a temporary trestle that is subject to repeated loads, vibrations, etc., in which a place with a turnbuckle interposed in the middle is fixed in the xtq* rotation direction, and the turnbuckle is A metal fitting is fixed and supported in the direction of movement at the end of the place screwed into the place, and the metal fitting is engaged with the turnbuckle in the direction of rotation to prevent the turnbuckle from reversing. It is constructed using the place construction method for temporary structures characterized by:

互摺動が無くなり同プレース３の緊張力は保持される。``Function'' The heavy temporary structure l formed by the vertical pillars 4, horizontal members 6, places 3, top cover plate or floor plate 7, etc. is subjected to repeated loads, shocks and shocks due to the operation of the dump truck 9, crane truck 8, etc. These forces act on place 3 as it receives vibrations. However, this place 3 has turnbuckle 2.
Because tension is applied in the longitudinal direction by can be restored. Then, due to the tension, compression, and vertical bending, the turnbuckle 2 receives rotational inertia along the screw thread to the return side due to the tightening of the screw, and the place end in the buckle 2 Since the metal fitting 5 supported by the metal fitting 5 engages with the buckle 2, the inertial rotation of the buckle 2 is prevented. Therefore, mutual sliding in the longitudinal direction between the buckle 2 and the place 3 is eliminated, and the tension force of the place 3 is Retained.

。These forces repeatedly act on the place 3 as tensile, compressive and bending forces. This place 3 consists of two 19 rods 3', 3' located at the same center as shown in FIGS. 1 and 2. The mutually opposite male threads 11.11 formed on the opposite ends of the tuning rods 3', 3' are connected to the mutually opposite female threads 12.12 formed on both ends of the turnbuckle 2. Connect both sticks 3' and 3' with wax, and then connect both IP13'
The flat plate 13 is welded to the other end of each of A and A, and the flat plate 13 is
A bolt hole 14 is drilled in the hole 14, and the other ends of the fR rods 3', 3' are connected to the upright column 4.4 directly or indirectly through the cross member 6, as shown in FIG. Two places 3.3 are installed between the vertical pillars 4.4 so as to intersect with each other. Therefore, rotation of the steel rods 3', 3' around the center line 3 is fixed, and the turnbuckle 2 can be rotated around the center line a to apply tension to the place 3. A protrusion 15 is provided at the tip of at least one of the steel rods 3 screwed into the buckle 2, and a through hole 16 formed in the metal fitting 5 is fitted into the protrusion 15. Protrusion 1

Opposing surfaces 15' and 16' are formed to prevent the metal fitting 5 from rotating around the center line a of the protrusion 15.
The protrusion 15 and the through hole 16 are formed in a cylindrical shape, and the through hole 16 is hexagonal (Fig. 3), quadrangular (Fig. 4, 5), semicircular (Fig. 6), or oval. It is also possible to form a concavo-convex strip for male and female fitting. The five metal fittings constructed in this manner are fixed without rotating around the center line a of the autonomous fittings 3'. As shown in FIGS. 3, 4, 7, and 8, this metal fitting 5 includes an arm 5' that engages with the turnbuckle 2 in the rotational direction.
5' is provided to prevent the turnbuckle 2 from rotating around the center line a of the steel rod 3. In the figure, numeral 17 indicates a bottle to prevent the metal fitting 5 from sliding and falling off, and 18 indicates a hole for the bottle.
