DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for lifting a structure such as a roof of a large space building such as a hangar or a factory, and joining the structure to a pillar.

[0002]

2. Description of the Related Art When building structures such as roofs of large space buildings such as hangars, factories, event halls, and gymnasiums, a lift-up method has conventionally been used. In the lift-up method, temporary columns are provided in addition to the main columns for constructing the building by joining the above-mentioned structures such as roofs, and after the temporary columns are used to lift the structure, the main columns are lifted. This is a method of joining structures to a building.

[0003]

SUMMARY OF THE INVENTION The above prior arts include:
The following problems exist. <A> Since the construction of the temporary columns is required, the construction cost is increased and the construction period is prolonged.

<B> When joining a structure to a main column, it is necessary to move the structure from the temporary column to the main column, which makes the joining operation difficult.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems, and eliminates the need for temporary pillars to reduce the construction cost, shorten the construction period, and simplify the joining work. It is an object of the present invention to provide a structure of a pillar for lifting and joining a structure and a method of lifting and joining the structure.

[0006]

Means for Solving the Problems That is, the present invention provides a column for joining by lifting the structure, and the supporting lifting unit causes out Zhang horizontally from the upper supporting region portion, placing the lifting structure thereof And a part of the structure installed vertically on the shelf
A space portion can be passed, provided integrally with the top supporting region portion, the more a joint for joining the lifting structure thereof,
These are columns for lifting and joining structures. Further, in the method of lifting a structure using the above-mentioned column, a part of the structure is partially removed from the space of the shelf by the lifting device installed above the joint.
And lifting the lower end of the structure to a height above the shelf by passing the structure through the section, and then placing the structure on the shelf.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. [1] Pillar Structure As shown in FIG. 1, a pillar 1 of the present invention is a main pillar for joining a structure to form a building, and a supporting portion 11, a shelf portion 12, and a joining portion in order from the bottom. This is a reinforced concrete pillar having an integral structure of the portion 14.

<A> Supporting part Since the supporting part 11 is a part for mainly supporting the weight of the structure, the supporting part 11 is designed and constructed to have a required rigidity in terms of its cross-sectional dimensions and the like. As shown in FIG. 2, the supporting portion 11 can secure a minimum gap L1 for lifting the structure 3 such as a roof assembled on the ground when the structure 3 is lifted. To construct.

<B> Shelf As shown in FIG.
Are formed so as to extend substantially horizontally on the lifting side of the structure 3. A space 13 is provided in the middle of the shelf 12. The space 13 is designed to have a size that allows a part of the structure 3 to pass through during lifting. The structure 3 suspended to a predetermined height is placed on the shelf 12, and the vertical load of the structure 3 is transmitted to the support 11 via the shelf 12.

<C> Joint The joint 14 is a pillar member integrally provided on the upper part of the support part 11 and has a smaller cross-sectional dimension than the support part 11. As shown in FIG. 2, the structure 3 of the support portion 11 and the joint portion 14
Is designed so that the surface of the joint portion 14 is retracted by L2. Therefore, the structure 3 in the lifted state
The gap L3 between the joint portion 14 and the gap L1 between the support portion 11 and the support portion 11 have a larger dimension. The gap L3 secures a space that allows the joining operation between the structure 3 and the joining portion 14 to be performed. When the structure 3 is joined to the joint 14, the horizontal load of the structure 3 is transmitted to the column 1 via the joint 14.

[2] Construction Method Next, a method of lifting and joining a structure using the column 1 configured as described above will be described. <B> Installation of lifting device and lifting jig The gantry 2 is installed above the joint 14. The gantry 2 is installed so as to protrude on the lifting side of the structure 3 and on the opposite side thereof, and a lifting device 21 is installed above the lifting side. A lifting jack or the like is used for the lifting device 21, and a hanging member 22 such as a steel rod is made to penetrate through the gantry 2. One lifting device 21 is provided on the gantry 2 to reduce the number and facilitate cost reduction and management. For that, FIG.
So that it can be lifted at one point,
A special hanging jig 31 is mounted on the structure 3. In the case of two-point suspension, it is difficult to adjust both lifting devices. However, in the case of single-point suspension, no adjustment is required, and the lifting operation is facilitated. Note that a reaction rod 23 such as a steel bar is provided on the opposite side to the lifting side of the gantry 2 so that the column 1 does not fall or deform to the lifting side when the structure 3 is lifted. The reaction rod 23 has an upper end fixed to the gantry 2 and a lower end fixed to a fixing portion 24 projecting from the opposite side of the shelf 12.

<B> Structure lifting columns 1 are to be provided at the planned positions of the side wall portions because they serve as support columns for the side wall portions of a building such as a hangar. Next, a structure 3 such as a steel truss structure serving as a roof of the building is assembled on the ground portion between the opposing columns 1. Further, a suspending jig 31 is attached to the upper end of the end of the structure 3 on the pillar 1 side.
To the lower end of the suspension member 22 suspended from the lifting device 21. Then, the lifting device 21 is operated to lift the structure 3 along the column 1. At this time, the support part 1 of the pillar 1
The gap L1 between the structure 1 and the structure 3 has a minimum dimension required for lifting, and the gap L3 between the joint 14 has a dimension required for joining.

<C> Joining of structures The structure 3 passes through the space 13 between the shelves 12 and
Is lifted to a position higher than the shelf 12. Then, as shown in FIG. 3, the receiving beam 5 is bridged between the shelves 12, and the structure 3 is placed on the receiving beam 5 or the like. Thus, the vertical load of the structure 3 can be stored in the shelf 12. Next, the joining members 4 and 41, such as a steel plate, are attached to the structure 3 and the joining portion 14, respectively. Then, by connecting these joining members 4 and 41 and joining the structure 3 and the joint 4 integrally, the horizontal load of the structure 3 is reduced to the joint 1.
4 can be transmitted. The joining member 4 may be attached in advance before lifting the structure 3.
Also, since the joining member 4 only needs to have a function of joining the structure 3 and the joining portion 14, various other structures other than the steel plate can be adopted.

[0014]

Since the present invention has been described above, the following effects can be obtained. <A> Since the structure can be lifted by the permanent pillar, a temporary pillar is not required. Therefore, it is possible to reduce the construction cost and the construction period.

<B> Since the lifting and joining work of the structure can be continuously performed with only the main pillar, the conventional moving work from the temporary pillar to the main pillar is unnecessary. for that reason,
The work of joining the structure to the main pillar can be simplified.

<C> The vertical load of the structure can be received by the shelf, and the horizontal load of the structure can be received by the joint. Therefore, the joining strength between the structure and the main pillar can be increased.
