Abstract

PURPOSE:To improve work efficiency by mounting a finish material on a truss with a high central part, fitting up the truss and another truss, tightening after deflecting a lower chord of another truss material downward and laying the finish material. CONSTITUTION:A truss 1a with the central part higher than both ends thereof is built up on a built-up stage 5, and after that, it is moved onto a rail 6. Then, after mounting a finish material 7 such as a roof and the like on the truss 1a, a truss 1b is built up, and a tie 8 of the truss 1b and the truss 1a are coupled with a fitting-up bolt. Then, a hydraulic jack is provided to right and left of the central part of the length of the truss 1b, drawing the lower chord of the truss 1b downward, deflecting downward from a chain wire 1c to correspond with a level of the lower chord of the truss 1a. In addition, the fitting-up bolt of the tie 8 is tightened, laying the finish material 7, and when the hydraulic pressure of the jack is reduced to zero, the jack is removed to released the forced deflection.

[Conventional technology] The traveling construction method has the advantage of being able to perform roof construction and lower frame construction in parallel to a building, but in order to take advantage of this advantage, finishing materials and equipment are installed immediately after the steel frame of the roof truss is erected. and then move to the construction site. In this case, the truss is designed so that the center part 31 of the truss 30 is higher than both end parts 32 and 32, as shown in FIGS. A truss assembled on a support material 33 is used, but there is a large difference in the carrying load between a truss with only a steel frame and a truss with finishing materials 34 and equipment attached. Regarding the load sharing of the assembled truss, as shown in Fig. 10, the connecting material 36 of the truss 30 is
The load applied to is 1/2 of one span, whereas the truss 30a from ■ street to ■ street, which was moved to the right from the temporary stage 35, supports the load of the entire span, so from the load sharing ratio 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 materials. It never happened.

[Problem to be solved by the invention] Recently, the length of trusses such as large-scale multipurpose halls is 1
In the traveling construction method for long trusses weighing over 1,000 m, there is a large difference in the amount of deflection at the center of the truss between when only the steel frame is used and when finishing materials are attached. For this reason,
In Fig. 10, the amount of deflection in the center of the truss is large between the ■ street and the ■ street, and when joining the steel frame connecting material 36 between the ■ street and C is gone, and even if the bolts can be temporarily tightened, if the final tightening is performed, temporary stage 3 will occur.
When the finishing material 34 is attached after moving from 5, the truss is bent, causing problems such as extra stress being generated in the member.

As a countermeasure for these problems, (a) Install the finishing material 34 after assembling the steel frame between the ■ street and the ■ street in advance, so that the truss 30b of the ■ street is deflected in advance due to the applied load. (or entrance) The finishing material 34 that was previously installed between the ■ street and ■ street will be replaced with ■ street and ■.
It is possible to reduce the deflection of the street truss 30a between the streets, but in the case of (a) above, the connecting material 3
6 are connected with temporary bolts, and the shearing force acting on the temporary bolts becomes large and there is a risk of insufficient strength.Additionally, the preliminary lifting and installation of finishing materials takes time, which lengthens the traveling process and delays construction work. There is a problem of delays in completion, and in the case of (b) above, an extra work stage and curing stage are required for work between ■ street and ■ street, which increases temporary construction costs and reduces work space. There is a problem that causes problems with lower structure work such as lower structure work.

In this state, due to its own weight and the weight of the finishing material 7, the center portion 2 of the truss 1a has a height equal to that between both end portions 3.3 and the gap. Next, in a third step, a truss 1b similar to the truss 1a is assembled on the assembly stage 5, and the connecting member 8 of this truss 1b and the truss 1a are connected by temporary bolting. Subsequently, in the fourth step, hydraulic jacks are attached to the left and right sides of the center of the length of the truss 1b to pull the lower chord of the truss 1b downward, and as shown in FIGS. Collect it downward as shown in , and match the level of the lower chord of the truss 1a in the second step. The details are shown in Figures 5 and 6.
As shown in the figure, a hanging metal fitting 11 reinforced with a reinforcing plate 10 at the front and back is welded to the lower chord member 9, and a pin 12 parallel to the lower chord member 9 is welded to the lower chord member 9.
A universal joint 14 is formed by a pin 13 perpendicular to the universal joint 14, and a hydraulic jack 17 is pivotally connected to an H-shaped steel 15 constituting the lower gantry by a pin 18 with a receiving seat 16, and the tip of the piston rod 19 of the hydraulic jack 17 is A screw 21 is screwed to the mounting piece 20 of the universal joint 14, and hydraulic pressure is supplied from the return port 22 of the piston using a manual pump or an electric pump to pull down the piston rod 19, thereby pulling the lower chord member 9 downward to a substantially horizontal state. 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.
Since the height of the truss 1b is lowered, the hydraulic jack 17 extends to the right by the amount that the height of the truss 1b is lowered.
Since the truss 1b is connected to the H-shaped steel 15 and the lower chord member 9 by the universal joint 14, no unreasonable force is applied to the truss 1b. After the 41st step, the bolts of the temporarily bolted connecting material 8 are fully tightened, and the finishing material 7 is laid as shown in FIG. As a result, the pressure of the hydraulic jack 17 that caused the forced deflection is gradually reduced, which is read by the pressure gauge, and when the pressure reaches zero, the fifth step is to remove the hydraulic jack 17 and release the forced deflection. By doing so, it becomes possible to easily connect long trusses using the traveling construction method.

[Effects of the invention] According to the method of this invention, the installation of the truss and finishing materials is completed by simply constructing the steel frame, and there is no difference in the level of the truss. (2)
Since there is almost no change in the amount of deflection of the truss after the bolts are fully tightened, no extra stress is generated at the joints of the connecting materials, and quality can be improved. In addition, (3) there is no risk that the strength of the bolts temporarily tightened will be insufficient, as is the case when finishing materials are installed in advance of steel frame erection, and (4)
There is no need to spend time pre-lifting finishing materials, so there is no delay in the construction period, and furthermore, finishing materials can be installed on a truss beyond the assembly stage, rather than on the truss immediately after it has been moved. (5) There is no need for extra stage temporary construction costs, and (6) there is no problem with lower work due to a reduction in work space.
