Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which a gate-shaped frame structure is incorporated into a framed wall construction building to form an internal space.

[0002]

2. Description of the Related Art Conventionally, in a wooden frame wall construction method based on a method of assembling a bearing wall by a wall framework on a floor slab, for example, the front surface of the first floor of a two-story or three-story building. When creating an internal space such as a garage or store where the opening width is equal to the space between the left and right supporting walls of the building, that is, the span is full, without forming a wall in the building, the above-mentioned wooden left and right supporting walls alone make up the upper building structure. Since it cannot be said that it has sufficient proof strength to support loads such as earthquakes and resist wind force and wind pressure, the internal space is constructed with a steel frame structure that is different from that of wooden buildings, There was no choice but to consider combining the structure and other wooden structures made by the original framed wall construction method.

[0003]

However, as described above, in a conventional wooden framed wall construction building, if a building portion of another structure such as a steel structure having strength instead of the bearing wall structure is incorporated, it becomes an eclectic building. In that case, a different construction method will be adopted, which will cause a problem in terms of economic efficiency such as high material costs, and the conventional frame wall construction method will be affected, including problems such as joint fitting. However, the technical burden was increased and there was a problem in workability.

In view of the above situation, the present invention provides a wooden framed wall construction building in which an opening formed by a wooden member having a sufficient proof strength capable of replacing the proof wall over the space between the left and right supporting walls, that is, the span. The purpose of the present invention is to provide a wooden building that can be constructed in space and therefore can be constructed within the framework of the conventional frame wall construction technique and is excellent in workability and economy.

FIG. 1 is a perspective view showing a skeleton state of a building of the present invention in which an opening without a wall is formed by applying a gate frame of a wooden ramen structure, and FIG. 2 is a gate frame of FIG. 1 showing a mounting state to a foundation. FIG. 3 is a partially cutaway perspective view of FIG. 3, FIG. 3 is a partial perspective view showing a rigid connection state between a vertical member and a horizontal member of the gate-shaped frame of FIG. 2, and FIG. 4 is a metal fitting to the lower end of the vertical member of the gate-shaped frame of FIG. 5 is a partial perspective view showing the installation situation of the floor set and the wall set in the building of FIG. 1, and FIG. 6 is a portal frame, the floor set and the wall according to another embodiment of the present invention. FIG. 7 and FIG. 15 are perspective views showing a construction situation of a set, respectively, and are schematic views showing a building according to another embodiment of the present invention.

In a building A having a two-story structure shown in FIG. 1, three portal frames 1 (1A, 1A, 1A, 1) having a space between left and right supporting walls, that is, an opening width of 1 span, in the front part of the first floor portion.
(B, 1C) are arranged side by side on the foundation 2 in the front-rear direction so as to create a space portion having no wall set or pillar inside.
With the intermediary of the portal frames 1A, 1B, 1C of the base,
The first-floor wall set 4 is constructed on the base 3 by the frame wall construction method, and the first-floor wall set 5 including the bearing walls on the left and right side wall parts and the rear wall part.
Is attached, and the corner post 6 is attached at the intersection of the load bearing walls. Then, the second-floor set 7 is constructed on the assembled first-floor wall set 5 by a conventional method, and the corner posts 8 are mounted on the second-floor set 7 and the second floor including the bearing wall. The wall group 9 is constructed, and further the roof group 10 is constructed.

As shown in FIG. 2, the gate-shaped frame 1 has two vertical members 11A and 11B each made of laminated wood.
And a horizontal member 13 horizontally joined to the upper portions of the two vertical members 11A and 11B by a steel L-shaped bonding metal plate 12. The length of the cross member 13 is adjusted to the distance between the left and right supporting walls of the building, that is, the span, and the steel joint fittings 14 are attached to the lower ends of the vertical members 11A and 11B, respectively.
When the vertical members 11A and 11B are mounted on the mounting base 2a of the base 2 via the joint fittings 14, as will be described later, the upper surface of the gate-shaped frame 1 is the upper surface of the joist of the second floor. It is set to be flush with the floor so that the underfloor of the second floor can be evenly attached.

Further, the vertical members 11A of the portal frame 1,
11B and the cross member 13 have a square or rectangular cross section having a sufficient thickness in the front-rear direction and a width in the left-right direction, which is thicker than the load-bearing walls of the first floor wall set 5, and are calculated to withstand the load of the superstructure. It has a rigid contact strength and at least a rigidity equal to or greater than the amount of wall required when building by the framed wall construction method. In addition, the laminated wood is characterized in that the dried sawn plate, the small square wood, and the like are laminated and bonded by an adhesive with the fiber directions parallel to each other, and there are few cracks and deviations and a strong compressive load.

To explain further, as shown in FIG. 3, the vertical member 11A and the horizontal member 13 are each formed with a cut groove 15 at the end thereof, and the cut metal 15 has an L-shaped joining metal plate 12. Both end portions are fitted and 24 pin holes 16 are penetrated from the side surface in a predetermined arrangement in the overlapping portion, and drift pins 17 are driven to fix the vertical member 11A and the horizontal member 13 to the joining metal plate 12. Thus, the vertical member 11A and the horizontal member 13 are joined together, and the vertical member 11B is similarly joined to form the portal frame 1. Although the number of the drift pins 17 is 24 in this embodiment, the number of the drift pins 17 is arbitrary depending on the portal frame.

In this case, the drift pin 17 for fixing the overlapped portion has an effective length of 8 times or more of the diameter in order to have toughness, and the joining metal plate 12 and the longitudinal member 1 are used.
1A, 11B and the cross member 13 overlap with the drift pin 1 at both lengthwise ends of the wood material.
7 or more times and 2 times or more of the margin of the diameter of 7, and
The widthwise edges of these wood materials are each provided with a blank space of 4 times or more the diameter of the drift pin 17, and the pitch between the drift pins is arranged to be 7 times or more of the diameter of the drift pin 17. As a result, a load having an arbitrary load angle by the combined force of the distribution force, the shearing force, and the axial force due to the moment applied to each drift pin 17 in the portal frame 1 is applied to the drift pin 17.
It does not exceed the short-term allowable proof stress of any load angle calculated by the arrangement of. Therefore, the gate-shaped frame 1 is configured as a wooden rigid frame structure in which the nodes are rigidly connected, and it has sufficient strength and tenacity to replace the bearing wall against external forces such as loads and seismic forces due to the upper building structure. Is to hold.

Further, as described above, the joining metal fitting 14 which is a base mounting portion is attached to the lower end portions of the vertical members 11A and 11B which are the leg portions of the portal frame 1. That is, as shown in FIG. 4, the joining metal fitting 14 has a plate portion 14a which is welded to each other.
And the box portion 14b, the plate portion 14a is fitted into the cut groove 18 formed in the lower end portion of the vertical member 11A to be superposed, and after fitting, a predetermined number of pin holes are formed in a predetermined arrangement by perforation from the side surface. Then, the drift pin for polymerization is driven into this pin hole to be fixed. Further, the box portion 15b is divided into two parts, front and rear, and two bolt holes 19 are preliminarily formed in each bottom face portion thereof so that the box portion 15b can be attached to the anchor bolt of the foundation 2 as described later. I am doing it.

The portal frame 1 thus constructed is
At the construction site, it is hoisted by a crane and mounted directly on the foundation 2. That is, the portal frame 1
Is mounted on a mounting base portion 2a having an overhang inside the base 2 as shown in FIG. When the foundation extends in a direction orthogonal to the foundation 2 along the outer wall portion of the first floor, the orthogonal portion may be used as the mounting foundation portion. An anchor bolt 20 is embedded in advance in the mounting base portion 2a so as to fit into the bolt hole 19 of the joint fitting 14,
By inserting the anchor bolt 20 into the bolt hole 19 and tightening the nut, the portal frame 1 is mounted and the foundation portion 2 is attached.
