Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an outer wall structure of a building by a unit construction method.

[Prior Art] Conventionally, as shown in FIG. 3 (first conventional example), in the case of a large wall that covers the wall surface of the pillar 1 flush, from the outer wall frame member 3 and the outer wall surface member 4 of the outdoor side U Since the wall thickness “t ₁ + B” of the outer wall panel 5 that is formed protrudes from the pillar 1 to the outdoor side U, the total wall thickness D ₁ is D ₁ = l + B + t ₁ + t ₂ when the thickness t ₂ of the inner wall 9 is added. It has a large thickness. However, B is the thickness of the outer wall frame member 3, and t ₁
Is the thickness of the outer wall surface material 4.

As a technique similar to the first conventional example, there is JP-A-61-176743 (prior application).

Further, as shown in FIG. 4 (second conventional example), in the case of the type in which the outer wall frame member is inserted between the beams 2 and 2 ', the thickness l of the pillar 1 is equal to the thickness t ₁ of the outer wall surface member 4 and the inner side. The total wall thickness dimension D ₂ including the thickness t _{2 of the} wall 9 can be made thin as D ₂ = l + t ₁ + t ₂ , but the outer wall surface materials 40, 41, 42 are divided into three.

As a technique similar to the second conventional example, there is Japanese Utility Model Laid-Open No. 58-138701.

Furthermore, as shown in FIG. 5 (third conventional example), in order to integrate the outer wall surface member 4 with the shape of the outer wall frame member shown in FIG.
It is necessary to add an auxiliary material 31 for the outer wall surface material 4 separately from the skeleton (stud) 30 or to thicken the outer wall surface material 4 itself to make it strong.

[Problems to be solved by the device]

However, in the case of FIG. 3, when the wall thickness “t ₁ + B” is added to the thickness 1 of the pillar 1 and the thickness t ₂ of the inner side wall 9 is further added, the total thickness D ₁ becomes very large, resulting in an increase in cost. In addition, the actual floor area is lost, which is disadvantageous to the owner, and there is a risk that the unit may come into contact with transportation restrictions (the width of the unit must be within 2,500 mm).

Then, in the case of FIG. 4, the number of parts and joints are increased due to the division of the outer wall surface material, the cost is increased, and the joints deteriorate the appearance.

Further, in the case of FIG. 5, the cost is increased by increasing the number of parts due to the addition of the auxiliary material for the outer wall surface material, or the cost is increased by increasing the thickness of the outer wall surface material 4.

Therefore, in order to solve such a problem, the present invention,
By devising and improving the horizontal installation of beams within the width of the pillar, the thickness of the entire outer wall panel mounting area can be reduced, and the outer wall structure of the building by the unit construction method that can minimize the number of constituent parts The purpose is to obtain.

[Means for Solving the Problems]

In the outer wall structure of the building by the unit construction method according to the present invention, the beam width of the beam of the building unit horizontally installed between the upper ends and the lower ends of the adjacent columns of the building unit is made narrower than the column width of the column. And, the narrowed beam is arranged to be shifted toward the indoor side within the width of the column, and the outer wall frame member that is integrated with the outer wall surface material and constitutes the outer wall panel of the building unit is formed by the column and the beam. It is characterized in that it is housed in a space formed on the outdoor side within the width of the pillar, and the outer wall frame member is attached to the outdoor side of the beam.

[Action]

According to the above configuration, the beam width of the beam laterally installed between the upper end portions and the lower end portions of the adjacent columns of the building unit is made narrower than the column width of the column, and then the beam is narrowed. Since it is arranged so as to be biased toward the indoor side within the column width, a predetermined space is formed on the outdoor side within the column width. Then, in this space, the outer wall frame member in the outer wall panel of the building unit is stored,
In this state, the outer wall frame member is attached to the outside of the beam.

As described above, according to the present invention, since the outer wall frame member is housed in the space formed on the outdoor side within the width of the column, the thickness of the entire outer wall panel mounting portion is reduced.

Further, according to the present invention, the beam width of the beam of the building unit is narrower than the column width of the column, and the beam is arranged on the indoor side within the column width, and the beam has outer wall frame members. Since the outer wall frame member is attached to the outside of the beam, the outer wall frame member is not directly placed. Therefore,
It is not necessary to divide the outer wall surface material into upper and lower parts as in the conventional structure.

Further, according to the present invention, for the same reason as described above, since the attachment strength of the outer wall frame member to the building unit is sufficiently secured, it is also necessary to supplement the outer wall surface member with an auxiliary member as in the conventional structure. Disappear.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 and 2 show an embodiment of the present invention,
As can be seen from FIG. 1, within the column width 1 of the column 1, beams 2a and 2b narrower than the column width 1 of the column 1 are provided above and below, respectively, and these beams 2a and 2b are placed on the indoor side R. Of the outer wall panels 5 that are laterally arranged close to each other, and on the outdoor side U of these beams 2a and 2b, the outer wall frame member 3 (specifically shown in FIG. 2) and the outer wall surface member 4 are integrated, Substantially all of the outer wall frame member 3 is housed in the column width l, and the outer wall frame member 3 is further fixed to the beams 2a and 2b by bolts 6 and nuts 7.

That is, in order to make the wall thickness as thin as possible with respect to the pillar 1, the outer wall panel 5 is formed so that the pillar width l + α = inner wall (kabeuchinori) dimension D. (Α; escape dimension) Therefore, assuming that the thickness of the outer wall frame member 3 is B and the beam width is C, B + C≈l (= l + α) is set so that the beam 2a,
2b is housed inside the column width l toward the room side R. (When the inner side wall 9 lowers to the position 9b when the floor is soiled, etc., it interferes with the beam 2b. It is necessary that the beams 2a and 2b are housed within the l)). As a result,
Substantially all of the outer wall frame member 3 of the outer wall panel 5 including the outer wall frame member 3 and the outer wall surface member 4 having a simple integrated structure is the column width l.
It is stored and provided inside. Further, since the outer wall panel formed by integrally forming the outer wall surface material 4 and the outer wall frame material 3 is fixed to the beams 2a and 2b, the outer wall panel substantially shares the force as a load bearing structure for supporting a lateral force. The above is also extremely advantageous.

When the floor (not shown) is accommodated above the beam 2b (lower beam), the inner wall 9 is accommodated at the position 9a, and therefore the beam 2b does not have to be accommodated within the column width l.

Further, the outer wall surface material 4 is attached in a vertically integrated manner by reducing the dimension E for the joint 8 from the height H of the outer wall frame material 3 (see FIG. 2).

Furthermore, the inner wall 9 shown by a chain line is attached by a normal construction method leaving a gap F in the beam 2b.

At the time of the earth floor, the inner wall 9 is formed so as to extend from the lower end 9a to the lowermost end 9b.

[Effect of device]

As described above, the outer wall structure of a building by the unit construction method according to the present invention has a beam width of a beam of a building unit horizontally installed between upper ends and lower ends of adjacent columns of the building unit. A beam narrower than the width, and the beam narrowed to the side is arranged to the indoor side within the width of the column, and the outer wall frame member that is integrated with the outer wall surface material to form the outer wall panel of the building unit is formed. Since the outer wall frame member was attached to the outer side of the beam while being housed in the space formed on the outer side within the width of the column by the column and the beam, the thickness of the entire attachment portion of the outer wall panel was reduced, and It has an excellent effect that the number of constituent parts can be minimized.
