Description of the Related Art Conventionally, in a wooden building, in order to provide an entrance having a wide and large opening such as a garage, it is necessary to use a vertical member provided with the opening width of the entrance on the left and right sides. A method has been adopted in which a portal frame having an upper end integrally connected by a beam member is used, and the portal frame having a large opening width and height is formed by standing the portal frame.

[0003] For example, there is a method described in Japanese Patent Application Laid-Open No. Hei 10-77700, and this method uses inner and outer pillar core members opposed to each other with a small interval on the left and right as shown in FIG. Column cores 50, 50 formed by connecting the opposing side surfaces of 51, 52 by a plurality of horizontal rails 53 are disposed on the left and right with the opening width of the entrance and exit and opposing inner column core members 52, 52. Beam core material between
61, the both ends of the beam core 61 are connected to the column cores 52, 52.
After forming a gate-shaped core material by nailing to
Attaching the load bearing surface materials 71 and 72 to the front and rear surfaces of this core material 81
To form a panel-type frame unit A ₂ having a panel structure, and a pair of the gate-type frame units A ₂ , A ₂ are superimposed one on the other and integrated back and forth to have a predetermined strength against vertical load. 2. Description of the Related Art Forming a portal frame having a constant thickness has been performed.

[0004]

However, according to the portal frame having the panel structure as described above, the joint strength is secured only by joining the face members 71 and 72 nailed to the front and rear surfaces of the core member by nailing. Therefore, in order to resist the horizontal load acting on the building due to the low shear strength of the entire frame, the strength of the portal frame with a single structure is insufficient,
Therefore, as described above, a pair of portal frame units
It is inevitable to integrally superposed A _2, A _2, there is a problem that it takes a significant effort to construction.

[0005] Furthermore, a load-bearing surface material is provided on the front and rear surfaces of the gate-shaped core material.
Pair the portal frame unit A _2, A ₂ together form a portal frame unit A ₂ single structure ensuring a predetermined joint stiffness by securing 71 and 72, together superimposed back and forth Since the opposing load-bearing face members 71 and 72 are brought into close contact with each other, the portal frame unit A ₂ is assembled in a state of being laid down in advance, and then the portal frame unit A ₂ is raised and raised as described above. The face materials 71 and 72 must be joined and adhered to each other, and the erecting work requires considerable labor and labor.In addition, the gate-shaped frame itself is used to form the entrance of a house with a full carport in the city. Since it is widely adopted, there are many construction sites in narrow places, and therefore, the assembling and standing work of the portal frame as described above becomes more difficult, and the workability becomes extremely poor. In addition, since the rising part of the foundation that fixes the lower end of the portal frame varies in width depending on the construction site,
There is a problem in that the design and construction of the gate-shaped frame corresponding thereto becomes complicated.

In addition, since the portal frame has a load-bearing wall structure made of a surface material, it is necessary to reduce the nail pitch for fixing the surface material to the core material in order to secure the joint rigidity of the gate-shaped core material. not only requires labor for the work there is, the portal frame is portal frame unit a ₂ as described above, a ₂
And a gate-type frame having a predetermined thickness is superimposed on the front and back, and then a gate-type frame unit is formed by nailing by covering a plate material on the beam upper and lower surfaces and both side surfaces of the pillars and the like of the gate-type frame. Since A ₂ and A ₂ are joined and integrated, the portal frame units A ₂ and A ₂ cannot be firmly integrated with each other only by connection through such a plate material. when a large horizontal load and the vertical load is applied to the portal frame unit a _2, the other portal frame unit
Also there is a problem in strength on not able to evenly share the load on the A _2.

[Operation and Effect] Since the ends of the upper and lower horizontal members are connected and tightened via a metal fitting fixed to the inner surface facing the upper end of the left and right vertical members, the left and right vertical members and the horizontal members are connected. Moment resistance of the joint is increased by constructing a frame structure that is firmly integrated via the joint hardware, and furthermore, the joint is covered and fixed with a load-bearing surface material, so the entire portal frame is Despite the fact that the shear strength is increased and the frame is of a unitary structure, it exerts excellent strength against the horizontal load applied to the building.

Further, since the frame is of a single-frame type, at the construction site, left and right vertical members are erected on the foundation, and then the upper and lower vertical surfaces of the vertical members are connected to the inner surfaces opposed to the upper end portions through metal joints. By connecting and fixing the horizontal members, a portal-shaped frame structure is formed, and the load-bearing surface material can be fixed to the portal frame body to form the portal frame. However, construction can be performed efficiently, and construction costs can be reduced. In addition, since the left and right vertical members and the horizontal member are firmly integrated with the joint metal, the installation of the load-bearing surface material can be easily and accurately performed, and the joint metal is attached to the opposed inner surfaces of the left and right vertical members. Since it is installed, it does not hinder any work for the construction of the load-bearing surface material, and after the construction of the load-bearing surface material, the joint metal is covered with the load-bearing surface material to give an excellent appearance. A portal frame can be built.

According to the second aspect of the present invention, the left and right vertical members constituting the portal frame are formed from a single column member having a thickness equal to the thickness between the front and rear surfaces of the horizontal member. As a result, the structure is simple, the workability can be simplified, the width of the opening between the pillars can be widened, and the end of the load-bearing surface material stretched between the upper and lower horizontal members Since the load-bearing surface material may be nailed to the horizontal member and the column material while covering the upper end portion of the column material, construction of the load-bearing surface material can be easily performed.

On the other hand, according to the third aspect of the present invention, the left and right vertical members are vertically spaced at small intervals between the opposing side surfaces of the pillars that are erected at small intervals inside and outside. Since it is composed of a panel that is integrally connected by a plurality of horizontal rails and is covered and fixed between the front surfaces of the pillars with a load-bearing surface material, it is strong and stable with a large load supporting force and excellent strength. Vertical members can be formed.

According to a fourth aspect of the present invention, a portal frame body is formed by the vertical member according to the third aspect and the upper and lower horizontal members. Both ends are tightened and joined to the upper end opposing side surface of the outer column member of the vertical member via a metal joint, while both end portions of the lower horizontal member are opposed to the upper end portion of the inner column member of the vertical member. Since the side walls are tightened and joined via a metal joint, a portal frame body having a framed structure having a stronger supporting force can be formed, and further, the axial center extension of the lower horizontal member can be formed. Since a short horizontal member is arranged between the opposing side surfaces of the inner and outer column members on the upper side, both ends of the short horizontal member are tightened and joined to the opposing side surfaces of the inner and outer column members via joining hardware, The strength of the vertical member is increased to obtain a portal frame having a wide and large opening. It is possible.
