Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling a wooden ramen in which a column member and a beam member made of wooden members are rigidly connected to each other with a reinforcing bar, and in particular, a three-story wooden structure constructed on a limited site. Suitable for buildings such as apartment houses.

[0002]

2. Description of the Related Art While the advantages of a wooden building have been re-recognized, a rigid wooden frame structure has been developed in which a beam-to-column connection is made of steel for bonding.

For example, Japanese Unexamined Patent Publication No. Hei 7-90937 discloses that a plurality of holes 3 having the same diameter are formed in both a wooden pillar member 1 and a wooden beam member 2 to be joined as shown in FIG. By joining a deformed reinforcing bar 4 in each hole, filling the hole 3 with an adhesive 5 such as an epoxy resin and curing the same, a wooden member called a rigid bar rigid connection for rigidly connecting the column member 1 and the beam member 2 is formed. A method is described.

[0004] Further, as for wooden members, those which have been subjected to secondary processing to improve the performance as structural members, such as a laminated veneer for structural use, have been used.

[0005] Such a wooden ramen structure has attracted attention because it is excellent in terms of workability and cost, particularly in a two-story, three-story house, an apartment house, and the like.

[0006] In addition, as a technique related to a wooden frame structure, Japanese Patent Application Laid-Open No. 7-62878 discloses an assembly and holding device used for rigidly connecting a wooden column member and a beam member to a steel frame structure in a wooden frame structure. Have been.

Japanese Patent Application Laid-Open No. 7-90937 described above discloses a method for constructing a wooden frame structure in which a beam joining protrusion is rigidly joined to a column member in advance, and the beam joining protrusion is attached to the pillar member. On the other hand, a method of joining beam members on site is described.

[0008]

SUMMARY OF THE INVENTION In the case of wooden ramen,
Since the beam-column joints and the like are rigidly joined, it is difficult to apply the conventional method of building a wooden building as it is. In particular, in the case of rigid reinforcing joints, pillars are set up one after another,
The task of joining beams while filling with adhesive is difficult.

As a method of assembling such a wooden ramen, the column member and the beam member are laid on the ground (ground erection), and after a curing period of about one week to 10 days, the adhesive is sufficiently cured. , Move the rigidly connected portal-type ramen or mountain-type ramen with a crane or the like and start up.
In general, the column base is fixed to the foundation, and the beam is joined between the adjacent ramen, so that a proper workability and assembling accuracy can be obtained.

[0010] Alternatively, as in the invention described in Japanese Patent Application Laid-Open No. 7-90937, a beam joining projection is rigidly joined in advance to a column member, and the beam member is joined to the beam joining project in-situ. The way to go.

However, in the case of a ground structure, a large plane space is required, and it is assumed that the site has a sufficient area. In addition, it is necessary to raise the grounded structure with a crane or the like, and there is a possibility that the members and member joints may be distorted when erecting.

Further, in the case where the projecting portion for beam connection is rigidly joined in advance with a reinforcing bar, the projecting portion not only obstructs the work, but also requires the columns to be erected individually, and a high position using a reinforcing bar and an adhesive. There is a problem that the work efficiency is poor because of the increase in beam joining work in the field.

The present invention is intended to solve the above-mentioned problems in the prior art, and can effectively utilize a narrow assembly space in a limited site, and is expected to have good workability and high assembly accuracy. It is an object of the present invention to provide an efficient and economical method of assembling wooden ramen.

[0014]

According to the present invention, there is provided a so-called reinforcing steel rigid connection in which a column member and a beam member made of a wooden member are rigidly connected via a reinforcing bar passing through a hole provided at a joint portion between the two members. In assembling a wooden ramen, a surface unit including a plurality of pillar members and one or a plurality of beam members constituting one surface is sequentially assembled in an assembling space on the premises in a state where the surface unit is erected. After assembling with multiple units arranged in parallel, after curing the assembled surface units,
It is characterized in that it is sequentially moved to a predetermined installation position and connected to a foundation, and adjacent structural units are connected to each other by beam members bridged between the structural units.

A second aspect of the present invention limits the case in which the joining of the column member and the beam member constituting the surface unit in the assembly space is performed on the scaffold of the support device, and the support device includes a plurality of parallel structures. It is installed so as to support the column member of the surface unit.

Although various forms of the support device are conceivable, for example, a framed scaffold type or the like can be used. After the support device is basically installed in the assembly space on the premises, it is fixed until the frame of the building is completed, but if the site area is not particularly large, it can be moved or moved as the work progresses. It is also conceivable to dismantle gradually.

[0017]

FIG. 1 shows an embodiment of an assembling method according to the present invention, in which a one-way wooden framed three-story building is located within a site boundary line a indicated by a one-dot chain line. It is assumed that a house is built.

In this example, a three-layer wooden beam member 2 is erected between two wooden pillar members 1 to construct a surface unit c, and the surface unit c is mounted on a foundation 6 already constructed. The wooden frame is assembled on the foundation 6 by connecting the adjacent structural units c with the wooden beam members 2 in the girder direction corresponding to each layer.

The assembling of the surface unit c is performed in the supporting device b installed in an assembling space set on one side of the site. In the drawings, the support device b is shown by a two-dot chain line in a simplified manner for easy understanding. For example, a framed scaffold type or the like can be used. Rigid reinforcement of the member 1 and the beam member 2 can be performed.

In the assembling space, a plurality of the surface units c are sequentially assembled and, while being supported by the support device b, are cured until the adhesive used for the rigid connection of the reinforcing bars hardens.

Since the surface unit c after curing is in an upright state, it is moved in parallel with a crane or the like to
It is fixed in the upper predetermined position. In the illustrated example, the reinforcing bar 4 is projected from the lower surface of the column member 1 of the structural unit c, and the reinforcing bar 4 is inserted into a hole formed in the upper surface of the foundation 6, and filled with mortar or the like and fixed.

Subsequently, as described above, the beam member 2 in the row direction is used.
By connecting adjacent structural units c with
A frame of the directional frame structure is formed.

[0023]

According to the invention of the present application, since the surface unit is assembled in an upright state, the occupied plane space is smaller than that of the terrain, and is limited when a low-rise apartment building is built up over the site area. Can be used effectively, and efficient construction is possible.

In the present invention, a plurality of surface units are arranged side by side in an upright state without being stacked as in the case of a terrain. Therefore, it is not necessary to raise the assembled surface unit with a crane or the like, and there is no problem such as deformation caused by the operation.

Curing can be performed while holding a large number of surface units in a small space, so that there is no waste in the work cycle.

By unitizing the surface unit, the work is easier and higher construction accuracy can be ensured than in the case where the column members are individually erected and the beam members are individually joined. Especially,
In the case of rigid reinforcing joints, if the accuracy is poor, it takes time to insert the reinforcing bar, etc., and the workability is greatly improved by securing the construction accuracy.

The assembling of the surface unit is performed by using a scaffold of a supporting device such as a frame scaffold assembled in an assembling space position.
Work can be performed continuously at the same position. In addition, the assembling of the surface unit requires almost no work of moving the scaffold, which is advantageous in terms of workability and economy.
