ことはなかった。[Conventional technology] The traveling method has an advantage that the roof construction of the building and the lower frame construction can be performed in parallel. To take advantage of this advantage, finishing materials and equipment are installed immediately after the steel truss construction of the roof truss. To move to the building site. In this case, as shown in FIGS. 8 and 9, the truss is set so that the central portion 31 of the truss is higher than both end portions 32 and 32 by a height corresponding to its own weight and the deflection caused by the load of the finishing material and equipment. Although the one assembled on the receiving material 33 is used, there is a large difference in the loading load between the truss with only steel frame and the truss with the finishing material 34 and equipment installed, and also on the temporary stage 35 of the steel assembly yard. Looking at the load sharing of the assembled truss, as shown in Fig. 10,
At 36, the load applied to the street truss 30b is 1 of 1 span because the street truss 30 is supported on the temporary stage 35.
/ 2, while the truss 30a on the street that moved to the right from the temporary stage 35 supports the load of the entire span, so a difference in load occurs between the two trusses based on the load sharing ratio. Therefore, there is also a difference in the amount of deflection of the truss. However, since the length of the conventional truss is relatively small, the difference in the amount of deflection is small, and there is no particular problem in joining the connecting members.

余分な応力が発生する等の問題がある。[Problem to be Solved by the Invention] Recently, the length of a truss such as a large-scale multipurpose hall has been increasing.
In the traveling method of a long truss exceeding 100m, there is a large difference between the case where the deflection amount at the center of the truss is only the steel frame and the case where the finishing material is attached. For this reason,
In Figure 10, the amount of deflection at the center of the truss differs greatly between streets, and bolt holes may not be aligned at the time of joining steel connecting material 36 between streets. Even if the truss is fully tightened, there is a problem that the truss bends when the finishing material 34 is attached after moving from the temporary stage 35 and extra stress is generated in the members.

れら問題を解決することを課題とするものである。As a countermeasure for these problems, (a) the finishing member 34 after the steel frame is assembled between the streets in advance, and the truss 30b on the street is caused to bend in advance by the loaded load, or (B) It is conceivable to reduce the amount of deflection of the truss 30a by performing the installation of the finishing material 34 between the streets between the streets. Are connected by temporary bolts, and the shearing force acting on the temporary bolts may increase.Therefore, there is a possibility that the strength will be insufficient. In the case of (b), there is a problem that the work is delayed and the work stage and the curing stage for the work between the streets are additionally required, so that the temporary construction cost is increased and the work space is reduced. There is a problem that caused the trouble in the lower working construction, and the like. An object of the present invention is to solve these problems.

するものである。Since the long truss 1 is deflected by its own weight and the load of the finishing materials and equipment, the central portion 2 is assembled so as to be higher than both ends 3, 3, and is moved to the rail 6 in front of the assembling stage 5 for finishing. When the material 7 is attached, the first truss
In order to connect with the second truss 1b in the high state of the central portion 2 by lowering the central portion 2 with the deflection of 1a, the connecting member 8 at the lower position at both ends of the second truss 1b After connecting the both ends of the first truss 1a at a low position with temporary bolts, the vicinity of the center of the lower chord 9 of the next second truss 1b to be connected is pulled down with a hydraulic jack 17 to forcibly bend. Not
Both ends of the first truss 1a are adjusted to the level of the lower chord of the first truss 1a so that both ends of the first truss 1a and the ends of the second truss 1b at the low position are tightened with bolts. Then, the finishing material 7 is attached to the second truss 1b to prevent the occurrence of extra stress or the like that occurs at the time of temporary bolt tightening due to mismatching of the bolt holes.

無理なく行うことが可能となる。That is, first, in FIG. 2, after assembling the first truss 1a in which the central portion 2 is higher than both ends 3 and 3 on the assembling stage 5 in the first step, the first truss 1a is moved from the assembling stage 5 to the first truss 1a. It is moved onto the front rail 6. In the second step, a finishing material 7 such as a roof is mounted on the truss 1a. In this state, the first truss 1a has substantially the same height at both ends 3 and 3 at the center 2 due to its own weight and the weight of the finishing material 7. Next, in the third step, the first truss is placed on the assembly stage 5.
The connecting member 8 at the low position of the second truss 1b similar to 1a is connected to both ends of the first truss 1a by temporary bolting. Subsequently, in a fourth step, a hydraulic jack 17 is attached near the center of the length of the second truss 1b to pull the lower chord material 9 of the second truss 1b downward, as shown in FIGS. 3 and 4. Chain line position 1c
From the lower end of the first truss 1a in the second step so as to match the level of the lower end of the lower chord of the first truss 1a in the second step. .
As shown in FIG. 5 and FIG. 6, the details are as follows.
A universal joint 14 is constituted by a pin 12 parallel to the lower chord member 9 and a pin 13 orthogonal thereto, and a hydraulic jack 17 is pivotally connected to an H-shaped steel 15 constituting a lower gantry by a pin 18 at a receiving seat 16 and a hydraulic jack 17 is provided. Piston rod
The tip of 19 is screwed 21 to the mounting piece 20 of the universal joint 14 and hydraulic pressure is supplied from the return port 22 of the piston by a manual pump or an electric pump to pull down the piston rod 19, thereby pulling the lower chord 9 downward and in a substantially horizontal state. To
At this time, in FIG. 4, the left end of the lower chord of the truss is fixed 5a on the assembly stage, but the right end is slidable 5b, so that the truss 1b extends to the right by the reduced height. However, since the hydraulic jack 17 is connected to the H-shaped steel 15 and the lower chord member 9 by the pin 18 and the universal joint 14, no excessive force is applied to the truss 1b. Thereafter, as a fifth step, the bolts of the connecting material 8 temporarily tightened are tightened, and then, as a sixth step, the finishing material 7 is laid as shown in FIG. As a result, the hydraulic pressure of the hydraulic jug 17 that caused the forced deflection is gradually reduced, so the pressure is read by a pressure gauge, and when the pressure becomes zero, the seventh step of removing the hydraulic jack 17 and releasing the forced deflection is performed. This makes it possible to easily connect long trusses in the traveling method.

The workability that can be easily performed is improved,
(2) Since the amount of deflection of the truss hardly changes after the bolts are fully tightened, the quality can be improved without generating extra stress at the joints of the connecting members. Also, as in the case of installing the finishing material after the steel frame construction,
(3) There is no fear that the strength of the bolts for temporary bolt tightening will be insufficient, and (4) there will be no time spent on the work for advance lifting of the finishing material, so that the construction period will not be delayed and the finishing material will be attached. (5) No extra stage temporary installation cost is required as in the case where the truss is moved from the assembly stage to the truss immediately after moving from the assembly stage, and (6) there is no hindrance to the lower work due to the reduced work space. .
