to the intermediate part of the other side of the ascending beam member.
[0014] It is preferable that the ascending beam member, the column member, and the ridge-side
beam support member have wood members having the same cross-sectional shape and different
length dimensions, for example, thinned wood of the same cross-sectional shape. Such
thinned timber is easy to obtain, and is also excellent in terms of cost reduction
and effective utilization of resources. As the other material of each member, a material
such as a metal material, a metal pipe, a resin material, a resin pipe, a bamboo material,
etc. may be selected, and a combination of a plurality of materials such as a combination
of wood and a metal material It may be selected.
[0015] Also, in the column and beam unit for the hut construction of the above-described
structure, and an eaves-side beam support member which is installed and connected
to the ascending beam member and the column member connected thereto is provided.
According to this constitution, the ascending beam member is provided with a ridge-side
beam support member linked with the other ascending beam member facing the other,
and the support is obtained from two directions by an eaves-side beam support member
installed on a column member to which the ascending beam member is connected.
[0016] Further, the end portions of the ridge-side beam support member and the eaves-side
beam support member are joined together at the Connection portion between the ridge-side
beam support member and the eaves-side beam support member of the ascending beam member.
Here, as a connection form of both members, they may be connected via a specific coupling
member. As the coupling member, for example, a metal plate may be used, after the
Connection portion of each member is covered with a metal plate, the member may be
screwed together with this.
[0017] In addition, in joining the end portions between the members, it is characterized

or a wing nut.
[0021] Here, as a pin coupling, there is a mode in which a pin formed on one side is fitted
(press-fitted) into a bush arranged on the other. As for the rigid coupling, as described
above, in addition to a mode in which each member is screwed and screwed after covering
the Connection portion of each member with a coupling member such as a metal plate,
when each member is a wooden material, There is also a mode of nailing.
[0022] Further, when the resin material and resin pipe, and the each members are good even
when adopting a form adhesive material is used. As the fitting and coupling, and a
cylindrical formed on one side, and the mode is fitted to the recessed part and the
other is formed of the same shape as the predetermined shape projecting part is of
square column. As the engagement bond, there is a form reference with each other a
protrusion formed on the both.

rotatable. As a result, it is possible to appropriately change the dimension between
the standing members between the column members and the tilt angle of the ascending
beam member, and it is also possible to fold the column members close to each other.
[0024] The hut structure using the column and beam unit having the above-described configuration
is characterized by having the following constitution. That is, the pair of ascending
beam members are held at a predetermined bending angle, and the column member is erected
and held at an installation position, and the column and beam unit for hut construction

beam member 2. The other ridge-side beam support member 4 is symmetrical with the
above one ridge-side beam support member 4 and the right upper end is symmetrical
with the ridge-side beam support member 4 of the upper joining portion which is lowered
from the ridge of the right-side ascending beam member 2 to the eaves girder side
and its lower left end is rigidly connected to the lower surface near the middle of
the left-side ascending beam 2.A pair of ridge-side beam support members 4,4 is arranged
so as to draw an approximately x-shape in which the upper side crosses the ascending
beam member 2 and the whole of the Present unit 1 is held in shape.
[0036] The ridge-side beam support member 4 positioned on the right side is connected to
the rear side with respect to the left ascending beam member 2 and the ridge-side
beam support member 4 positioned on the left side is connected to the front side with
respect to the right ascending beam member 2 and is connected to the front side of
the ridge-side beam support member 4 on the right side. The intersections of the ridge-side
beam support member 4 are also connected by the same connection means 7 as the other
members.
[0037] An eaves-side beam support member 5 is connected to each column member 3 so as to
be connected to the ascending beam member 2 to which the column member 3 is connected.
Specifically, one eaves-side beam support member 5 is connected at the lower right
end to the upper side of the right side column member 3 and below the connection position
of the ascending beam member 2, and the left upper end thereof is connected to the
right ascending beam member 2 to the lower surface side in the vicinity of the middle
of the two. The other eaves-side beam support member 5 is symmetrical with the one
