DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of lifting a building frame for performing a steel frame work, a roof work, an inner and outer wall finishing work, etc. of a building such as an experimental building and a gymnasium having a medium-sized large space.

[0002]

2. Description of the Related Art Conventionally, in a construction of a building having a large space, a scaffold is assembled in parallel while constructing a steel frame, the scaffold is removed after the steel frame is completely tightened, and a scaffold for internal finishing is assembled again. After the internal finishing, the scaffold is removed. Therefore, for example, the following construction method has been proposed.

[0003] (1) A frame of an outer peripheral wall or a pillar is constructed, a steel frame and a finish of a roof are assembled on the ground and lifted up, and a scaffold is assembled to finish inner and outer walls (lift-up method). (2) Assemble the steel frame and the finish of the roof part on the ground, push up several times while adding the frame of the wall or the pillar below, and finish the inner and outer walls with the scaffold (push-up method).

[0004]

As described above, in the conventional construction method, it is necessary to assemble the scaffold to a level close to the ceiling in order to finish the inner and outer walls on the outer periphery, so that there are many temporary materials and the work at a high place is required. The construction period was lengthened, and there was a problem in surrounding safety. This is because if lift-up or push-up is performed while finishing the inner and outer walls, structural problems will occur with respect to wind pressure and seismic force during construction.

[0005] In addition, the method of continuous push-up several times has a complicated jacking device and cannot be adopted in a medium-sized building from the viewpoint of cost.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method of lifting a building frame in which the number of scaffolds, labor and work at heights are reduced, the construction period is shortened, costs are reduced, and the surrounding safety is improved. .

[0007]

According to the lifting method of the building frame of the present invention, after the pile, the foundation or the foundation beam is constructed, the pedestal having the jack at the upper part at a required position such as the four corners of the frame is provided. Erect the roof truss, lay the roof truss at a height close to the ground, set the wire in the jack, connect the wire to the roof truss, operate the jack to lift up the roof truss, and the lifted roof truss Finish the roof and outer wall by assembling the first outer wall truss divided into several parts under the roof, lift up the roof truss and the first outer wall truss and lift the second outer wall under the first outer wall truss Finish the outer wall by attaching a three-dimensional truss,
Thereafter, the outer wall truss is assembled under the outer wall truss which is sequentially lifted to finish the outer wall, and the final outer wall truss is assembled and fixed to the foundation to finish the outer wall and remove the gantry.

Further, according to the present invention, the lower portion of the outer wall space truss is supported by the base plate and is positioned by the stopper.

[0009]

According to the present invention, for example, 1 /
With a height of about 5, most construction is possible, and construction can be done safely and quickly without causing structural problems against wind pressure and seismic force during construction.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

(1) A gantry installation step (FIGS. 1 and 2). After constructing the pile 1 and the foundation or foundation beam 2, for example, for the plane A having a frontage W of 40 m and a depth D of 25 m, the gantry 3 is placed on the foundation or foundation beam 2 at the middle of the four corners and the frontage W, respectively. Stand up. The specifications of the pile 1, the foundation or foundation beam 2, and the gantry 3 are determined so as to withstand external force during construction. The gantry 3 is provided with a jack 4. (2) Roof truss construction process (Fig. 3). Roof truss 10 is laid at a height close to the ground, and jack 4
Set the wire 5 on the roof truss 1
Connect to 0. (3) Roof and exterior wall finishing process (Fig. 4). The roof truss 10 is lifted up by expanding and contracting the jack 4, and for example, the first outer wall three-dimensional truss 12 a divided into five is assembled under the roof truss 10 to finish the roof 11 and the outer wall 13 a. (4) Second outer wall finishing step (FIG. 5). The roof truss 10 and the first outer wall truss 12a are lifted up, the second outer wall truss 12b is assembled below the first outer wall truss 12a, and the outer wall 13b is finished. (5) Lift-up completion step (FIG. 6). The outer wall finishing step is performed up to the fifth outer wall three-dimensional truss 12e, the outer wall truss 12e is fixed to the foundation 2, and the outer wall 13e is finished to complete the lift-up. (6) The stand removal process (Fig. 7). The gantry 3 is removed, and the roof truss 10 and the outer wall three-dimensional truss 12
Then, a shutter or the like (not shown) is attached to the completed building frame B of the outer wall 13 to complete the work.

As described above, according to the present invention, the building frame can be effectively lifted up and constructed, and the gantry only needs to have a certain height, and the construction period is shortened. .

FIGS. 8 and 9 show a preferred mode of supporting the outer wall space truss 12. FIG. A mortar layer 13 is formed on the base 2, and a base plate 15 is provided on the mortar layer 13, and the base plate 15 is fixed by anchor bolts 14. The outer wall space truss 12 having the rib 12n is mounted on the base plate 15. A plurality of (two in the illustrated example) fasteners 16 are movably fixed to the base plate 15 by screws 18 by long holes 17 provided in the base plate 15.

Therefore, the front and rear, right and left positions of the lower part of the outer wall truss 12 can be set correctly by setting the stopper 16 at a predetermined position and making the lower part of the outer wall truss 12 along the stopper 16. By doing so, the accuracy of the position of the outer wall space truss can be improved, and after the last lift-up, the lower portion of the outer wall space truss 12e may be fixed to the base plate by welding.

[0015]

As described above, according to the present invention, most of the steel work, the roof work, and the inner and outer wall finishing works can be performed on the ground, and the safety due to the saving of temporary materials and the reduction of work at a high place can be achieved. , Shortening the construction period, improving surrounding safety, and reducing costs.

In addition, compared to the conventional construction method, it can be implemented on a light-weight and small-scale frame, and horizontal deployment is easy.
