DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for erection of a suspended roof, which is installed between columns by lifting up suspended members assembled on the ground.

[0002]

2. Description of the Related Art There are two methods for constructing a suspended roof: a method in which the roof is erected and then raised using a crane, and a method in which the roof is constructed on a total scaffold assembled under the roof. However, because the suspended roof has low rigidity, the former method loses stability in the presence of wind, which affects the progress of construction, and the latter method requires much time and expense for temporary construction. become.

The present invention has been made in view of the problem of the conventional method of constructing a suspended roof, and proposes a method which does not require a construction period and a construction cost while ensuring stability.

[0004]

According to the present invention, a suspension member is constituted by a steel member that bears tension and a laminated material that surrounds the steel member and bears a bending moment, and a plurality of suspension members are provided in a state where tension is introduced into the suspension member. By lifting the unit made of hanging material, the instability during lifting due to insufficient rigidity of the suspended roof will be overcome, and the construction period will be shortened and the construction cost will be reduced.

The hanging members constitute a hanging roof in parallel in one direction, and a plurality of hanging members are assembled on the ground as a unit during lift-up. The unit is lifted with tension applied to the hanger between previously opposing columns at a distance.

Prior to assembling the suspending members, the supporting members are erected on the suspending roof side of the opposing columns on the plane at a distance in the direction in which the suspending members are arranged in parallel, and are movable in that direction. A lift is erected between the parallel columns so as to be able to move up and down on the columns,
A wire is stretched from the lift to the ground via the top of the pillar,
One end is connected to the lift and the other end is connected to the winding device.

After the temporary work is completed, the unit is assembled on a lift facing the direction in which the columns face each other, and the tension is applied to each of the hanging members of the unit, and the lift is raised to end each of the hanging members. Is connected to the top of the pillar to complete the installation of the unit. Thereafter, the lift is lowered and the support is moved by a fixed distance, and the procedure from assembly of the unit on the lift to movement of the support is repeated to complete the installation of all units, thereby completing the suspension roof.

A suspended roof unit, which is a unit for lift-up, has resistance to out-of-plane force by introducing tension into the suspended material, and has a shape maintaining ability due to the bending rigidity of the laminated wood, and stability against wind at the time of lift-up. To secure.

[0009] In addition, the strut and the lift necessary for lifting up the hanging material move in the direction in which the hanging materials are arranged in parallel with each installation of the unit, whereby the construction is continuously performed, and the progress of the construction is achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a method for assembling a part of a suspended roof 2 in which hanging members 3 are arranged in parallel in one direction as a unit 20 on the ground, and then constructing the preceding and constructing a pillar 1 facing away at a distance. , 1 in which the unit 20 is lifted and erected.

As shown in FIG. 8, the suspending member 3 is composed of a steel member 31 which bears a tension and a laminated member 32 which surrounds the steel member 31 and bears a bending moment. , And retains the shape maintaining ability from the time of lifting the unit 20 due to the bending rigidity of the laminated wood 32.

FIG. 1 shows a lift-up procedure of the suspended roof 2, and FIG. 2 shows a partial plan view thereof. The columns 4 are erected so as to be movable in the direction in which the columns 3 are arranged in parallel. The columns 4 and 4 move each time the lift-up of the unit 20 is completed along the rail 5 laid in the direction in which the columns 1 are arranged in parallel.

A lift 6 is erected between the parallel columns 4 and 4 so as to be able to move up and down with respect to the column 4, and a wire 7 is stretched from the lift 6 to the ground via a pulley 9 connected to the top of the column 1. One end is connected to the lift 6 and the other end is connected to a winding device 8 installed on the ground. The lift 6 moves up and down along rails 10 laid on the columns 4.

As shown in FIG. 3 which is a detailed view of FIG. 2, and FIG. 4 which is a cross-sectional view of FIG.
This is performed for each unit 20 consisting of Unit 20 is pillar 1,
1 is assembled on the lifts 6 facing each other in the opposite direction using the ground gantry 11 assembled between the lifts 6, 6, and the adjacent hanging members 3 are maintained at intervals by the connecting hardware 12. Linked to each other. The position adjustment of the hanging member 3 is performed by adjusting the position of the pedestal 14 on which the hanging member 3 directly rests with the jacks 13 at both ends. After the assembly of the unit 20, tension is introduced into the steel material 31 of each hanging member 3 by its own weight (gravity), and lift-up is performed with the tension applied to the hanging member 3.

After assembling the unit 20 shown in FIG. 5, the lifts 6 and 6 are raised by winding the wire 7 by the winding device 8 (FIG. 6), and the end of each hanging member 3 is placed on the top of the pillar 1. When lifted up, the end of the hanging member 3 is connected to the top of the pillar 1 (FIG. 7), and the installation of the unit 20 is completed.

Thereafter, the lifts 6 and 6 are lowered, and the columns 4 and 4 are moved by a predetermined distance. After the unit 20 is assembled on the lifts 6 and 6 shown in FIG. 5 again, as shown in FIGS. Repeat the procedure of raising the unit 20 and connecting the suspending material 3 to the pillar 1 so that all units 20 are
And the suspension roof 2 is completed.

After the suspension roof 2 is completed, the pillars 4 are removed, but the pillar 1 bears a compressive force on the suspension roof 2 side and a tensile force on the outside of the suspension member 3 against the tension of the suspension member 3. 3
And keep a balance.

[0018]

The present invention is as described above. A suspension member is constituted by a steel member which bears a tension and a laminated material which surrounds the steel member and bears a bending moment. Since this method lifts a unit consisting of hanging materials, the unit has resistance to out-of-plane forces by introducing tension into the hanging material, and has a shape maintenance ability due to the bending rigidity of the glued laminated wood. The stability against the wind at the time of up can be secured. As a result of erection by lift-up, the construction period can be shortened and construction costs can be reduced.

Further, the struts and lifts necessary for lifting up the hanging members are moved continuously in the direction in which the hanging members are arranged in each installation of the unit, whereby the construction is carried out continuously, and the progress of the construction is achieved.
