BACKGROUND OF THE INVENTION This invention, using a pillar joining brackets
For details on the building construction method, rotate the pillars from the laid state
It relates to a building method for erecting and assembling a building.

[0002]

2. Description of the Related Art Conventionally, as a construction method for houses and other buildings for houses, a construction method as shown in FIGS.
That is, after the base 302 is fixed on the foundation 300, pillars 304 such as through columns and studs are erected on the base 302, and the eave girder 308, the beam 310, etc. are fixed to the upper end of the pillar 304, and A construction method is used in which a roof 316 is constructed by assembling 312 and rafters 314 to form the entire framework of the building.

Here, in the example of FIG. 9, the fixing structure between the lower end of the pillar 304 and the base 302 has a structure as shown in FIG. Specifically, a tenon at the lower end of the pillar 304
Mortise 320 formed in base 302
9 and is fixed (see A in FIG. 9).
Part shown with).

The upper end of the pillar 304, the beam 310 and the eaves girder 3
08 and the like, as shown in FIG.
A tenon 318 provided at the upper end of the beam 310 and the end of the beam 310 is inserted into a tenon hole 320 formed in the eaves girder 308, and then fixed with a metal fitting (feather plate bolt) 328 (shown by B in FIG. 9). part).

Similarly, the fixing of the column 304 to the body insert 322 or the beam 326 (portions indicated by C, D, E and F in FIG. 9) is performed as shown in FIGS. 10 (C) to 10 (F). The tenon 318 provided on the trunk 322, the beam 326, the pillar 304, etc. is inserted into a mating member 320, ie, a tenon 320 formed on the pillar 304, the trunk 322, etc., and then fixed with a metal fitting 328.

[0006]

However, in the case of such a conventional construction method, it is necessary to work on a high place after assembling a scaffold, and to lift various building materials such as beams using a crane. Because of the necessity, the work is difficult, requiring a skilled work and increasing the cost. Further, there is a problem that the work is dangerous and a crash may occur in some cases.

[0007]

The invention of the present application has been made to solve such a problem. Thus, the invention of the present application is to assemble a roof structure above a top end of a pillar, including a horizontal structure member such as a beam or an eave girder as a roof structure member, into a final shape in advance, and to provide an upper end portion of the pillar Of the roof structure assembled into the final shape, is rotatably connected to a mating member to which the column is to be joined by a column joining bracket , and the lower end of the column is lower than the lower end of the column. for the mating member of the structure leave rotatably connected at column joining bracket is raised the upper and lower ends thereof pillar from the state laid down the pillar while relatively rotated with respect to each mating member Then, the upper end and the lower end of the pillar are non-rotatably fixed to the corresponding counterpart member to assemble the building.
As described above, the column joining metal fitting includes a metal fitting body and a fixing piece.
Wherein the fixing piece is fixed to an end side surface of the pillar.
The metal fitting body is connected to the mating member to which the pillar is to be connected and the pillar.
On the other hand, a fitting fixing portion that fits with substantially no gap,
Form a plate and sandwich the column and the mating member vertically
And one of the upper and lower surfaces is in close contact with the lower or upper surface of the pillar
Abuts and supports the column or is supported by the upper end surface of the column.
And a holding plate serving as a supporting surface, and
The piece is located at the joint between the pillar and the mating member, and
Around an axis located outside the column in the plane direction of the support surface
It is rotatably connected to the metal fitting body (claim 1).

According to another aspect of the present invention, in claim 1, the building is a two-story building, wherein the pillar is a pillar on a second floor, and a lower end of the pillar on the second floor is thereby rotatably connected to the horizontal structural members boundary between second floor and the first floor, the respective upper ends of the pillars of the first floor portion relative horizontal structural members, also on the base of the lower portion pillar For joining
It is connected rotatably with metal fittings , and those 2nd floor part and 1
The two-story building is assembled by rotating and raising each pillar of the floor portion from a laid state, and fixing each upper end and lower end to the corresponding counterpart member so as not to rotate. 2).

[0009]

As described above, according to the present invention, the lower end and the upper end of the column are rotatably connected in advance to a mating member to be joined by using a column joint fitting , and the column is connected to these members. It is configured to stand upright while being rotated relative to the counterpart member, and to be non-rotatably fixed to each counterpart member to construct the framework of the building.

According to the present invention, it is possible to assemble the roof structure in advance and lift the column together with the pillar when the column is rotated. Therefore, according to the present invention, it is possible to obviate the need to perform various high-place work after assembling a scaffold when building a building, and to lift various building materials to a high place using a crane or the like. Can be eliminated,
The construction cost of the building can be reduced, and dangerous work at high places can be omitted, and the occurrence of a crash or the like can be avoided.
In addition, there is an advantage that construction work can be performed without the need for skilled workers at high places.

Further, in the present invention, the roof structure above the upper end of the pillar is assembled into a final shape in advance, and then the pillar is rotated to lift the roof structure. It can be firmly assembled to the assembly structure, and this can be made into a strong structure.

Further, in the present invention, a fixing member fixed to a side surface of an end portion of a pillar is provided on the fitting so as to be rotatable with respect to the fitting main body. This is provided with each fitting and fixing portion with a mating member.

[0013] By using the column joint fitting, it is possible to favorably raise the column by rotating the column from a laid state while maintaining the connection between the end of the column and the mating member. Thus, it is possible to firmly fix the end of the pillar after standing up so as not to rotate relative to the counterpart member.

In addition, in the case of this column joint fitting, the lower end surface or the upper end surface of the column is brought into close contact with the supporting surface of the fitting, and the axis of the connecting portion between the fixing piece and the fitting body is
Since it is located outside of the surfaces in close contact and at the joint position between the column and the mating member, the upper load is not applied to the axis, and the column and mating member are formed by the column joint fitting by an excessive load. This has the advantage that the connection with the metal is not loosened and the metal fitting is not damaged or broken.

Further, in the case of this column joint fitting, a plate-like holding member is provided.
The holding plate has one of the upper and lower surfaces
The supporting surface is in close contact with the lower or upper surface of the pillar
On the other hand, even on the surface opposite to the support surface,
Due to the close contact, the load on the upper part is
To the lower member, that is, not only the shaft but also the
The body is not directly loaded by the upper part.
And therefore excessive load is applied to the column fittings including the shaft
No loosening of joint between column and mating member, damage to metal fittings
-Destruction can be more reliably prevented.

The invention according to claim 2 is for a two-story building.
At the top of the first floor,
Part and the lower end are non-rotatably fixed to the mating member.
According to the present invention, in the case of a two-story building,
Even then, rotate the whole and assemble it into the final shape
