  However, it is necessary to attach the rafter 8 that forms the other end 2b of the roof portion 2 to the outer wall T1 of the building main body T such as a house by screwing or the like. It has been necessary to open a hole, and it is necessary to install an adjustment member between the building external structure A and the outer wall T1.

  In view of the above circumstances, the present invention provides a building exterior structure that can flexibly cope with the unevenness of the outer wall of the building body and can reliably prevent the appearance from deteriorating and the gap between the building body and the outer wall. With the goal.

  In order to achieve the above object, the present invention provides the following means.

The building exterior structure of the present invention has a front wall, a roof provided with one end connected to the front wall, one end connected to the front wall, and an upper end connected to the roof. A side wall portion provided as a building exterior structure constructed by building the other end side of the roof portion and the other side end side of the side wall portion next to the outer wall of the building body, The external structure main body comprising the front wall portion, the roof portion, and the side wall portion, the other end of the roof portion and the other side end of the side wall portion of the external structure main body, and the outer wall of the building main body An intervening structure interposed between the outer wall and the intervening structure, with one side spaced from the outer wall where the opening of the building body is formed and facing the outer wall. The external structure is provided, and the other side includes at least the roof portion and a support column that supports the roof portion. A U-shape consisting of a pair of vertical members connected to the top end of the roof portion of the object main body and erected with the lower end portion buried in the foundation, and a cross member connected at the upper ends of the pair of vertical members comprising a Jo frame body further includes a closure member for closing the gap between the outer wall of the building body being disposed opposite to one side of one side and the frame body of the frame body, wherein The closing member attached to the vertical member is fixed to the vertical member so that one end portion covers at least a part of the side surface of the vertical member, and the other end portion is in contact with the outer wall of the building body. It is characterized by.

In the building exterior structure of the present invention, the closing member closes a gap in a side part between the frame and the outer wall of the building body between the frame and the outer wall of the building body. It is desirable that the first closing member is provided and a second closing member for closing an upper gap between the frame body and the outer wall of the building body.

  In these inventions, a substantially U-shaped frame body made up of a pair of vertical members and cross members is provided with a gap between the outer wall of the building body, and side wall portions are provided on the pair of vertical members of the frame member. A building exterior structure such as a solarium can be constructed by connecting the side end portion of the roof portion to the front end portion (the other end) of the roof portion. And even if there are irregularities on the outer wall of the main body of a building such as a house, by connecting the frame body in advance with a gap between the outer wall and the front wall portion, An external structure body comprising a roof portion and side wall portions can be constructed.

  Further, the side gap between the frame body and the outer wall of the building body is closed by the first closing member, and the upper gap between the frame body and the outer wall of the building body is closed by the second closing member, so that the outside Rain water and outside air can be prevented from entering the interior of the structure (indoor).

  Furthermore, for example, even when snow accumulates on the roof and a snow load acts or wind pressure acts, the tip of the roof (rafter hanging, tip girder) is connected to the U-shaped frame to support it. And since the rigidity is raised, it can suppress that a deflection | deviation arises in the front-end | tip part of a roof part compared with the past.

  In addition, the first closing member and the second closing member are interposed between the external structure main body and the outer wall of the building main body instead of the front end of the roof part, so that the frame does not easily displace even when snow load or wind pressure is applied. By being connected, even if snow load or wind pressure acts, the gap provided between the frame body and the outer wall of the building body is surely closed by the first closing member and the second closing member, and this state It becomes possible to hold.

Furthermore, in the building exterior structure according to the present invention, the second closing member includes a frame-side closing member disposed by fixing one side end portion side to the upper end portion of the frame body, and one side end portion side of the second closing member. and a closing and secured to the outer wall of the building body disposed the outer wall member, the other end side of the frame side closing member is arranged so as to overlap the other end portion side of the outer wall side closing member It is more desirable.

  In this invention, the second closing member that closes the gap between the frame body and the upper part of the outer wall of the building is composed of two members, the frame side blocking material and the outer wall side blocking material, and the other side of the frame side blocking material. By disposing the end side on the upper surface side of the other side end portion side of the outer wall side blocking material, this displacement can be absorbed when a relative displacement occurs between the frame body and the building body, It can prevent more reliably that a clearance gap arises.

  Further, in the building exterior structure of the present invention, the frame side closing material is formed by bending the other side end portion upward with respect to the one side end portion side, and the outer wall side closing material is formed with respect to the one side end portion side. The other side end portion is bent downward, the other side end portions of the frame side closing material and the outer wall side closing material are engaged with each other so as to be relatively displaceable, and the frame side closing member is connected. It is further desirable that at least one bent portion of the material and the outer wall side closing material is formed as a hinge portion.

  In this invention, the second closing member that closes the gap between the frame body and the upper part of the outer wall of the building is composed of two members, the frame side blocking material and the outer wall side blocking material, and the other side of the frame side blocking material. The end side is bent upward, the other side end side of the outer wall side closing material is bent downward, and the other side end sides are overlapped and engaged with each other, so that the frame body and the building body are connected. When a relative displacement occurs between the two, the displacement can be absorbed, and the generation of a gap can be further reliably prevented.

  Further, since at least one bent portion of the frame side closing material and the outer wall side closing material is formed as a hinge portion, when the relative displacement occurs between the frame body and the building main body, It bends at the hinge and can reliably absorb the displacement. Therefore, it becomes possible to more reliably prevent rainwater, snowmelt water, outside air and the like from entering the room due to a gap.

  In the building external structure of the present invention, even if the outer wall of the building main body such as a house has irregularities, it is interposed between the outer structure main body and the outer wall including the front wall portion, the roof portion, and the side wall portion. It is possible to efficiently construct a building external structure by interposing a frame of the mounting structure and connecting the frame to the external structure main body.

  In addition, since the roof portion of the external structure body is supported by connecting to the substantially U-shaped frame body, it is possible to bend the leading end girder of the leading end portion (the other end) of the roof portion as compared with the conventional case. Even if a snow load or wind pressure acts, the gap provided between the frame and the outer wall of the building body can be blocked by, for example, the first closing member and the second closing member, and this state can be maintained. It becomes possible.

  Therefore, according to the building external structure of this invention, it can respond flexibly to the unevenness | corrugation of the outer wall of a building main body, and it can prevent reliably that a clearance gap generate | occur | produces between the deterioration of appearance and the outer wall of a building main body.

A roof material 18 such as a plate or a glass plate is provided. Moreover, in this embodiment, the adjacent rafter 9 is connected by the middle aggregate (connecting material) 19 extended in the horizontal direction S1, and the roof part 2 is comprised.
Note that the rafters 17, the rafters 9, and the middle aggregates 19 constituting the roof portion 2 are also formed by using aluminum extruded shapes.

  Each of the pair of side wall portions 3 of the external structure main body B1 is formed, for example, with the waist wall portion 4 and the daylighting wall portion 11 like the front wall portion 1, or with a window, or the folding door 20 It is constructed by appropriately selecting a configuration such as forming a door or door so that it can enter and exit, or eliminating the waist wall portion 4 and only the daylighting wall portion 11.

  In this embodiment, one end is connected to the upper end of the front wall 5 of the front wall 1 and the other end is connected to the front 5 of the side wall 3 on the outer wall T1 side of the building body T. Shaped beams 21 are horizontally installed along the depth direction. Furthermore, a polycarbonate or the like (FIX window 22) is installed in a substantially triangular frame surrounded by the end beam 21, end rafter 9 and end column 5, or an inward window that falls down indoors is installed, and the side wall Part 3 is formed.

On the other hand, as shown in FIGS. 1, 2, and 3 , the interposed structure B < b > 2 of the present embodiment includes a pair of longitudinal members 25 and a transverse member 26 that connects upper ends of the pair of longitudinal members 25. The frame body 27 is provided. Further, the frame body 27 is disposed so as to be opposed along the outer wall T1 of the building body T, and is erected with a predetermined interval (gap H) between the frame body 27 and the outer wall T1 of the building body T.

  Here, the frame body 27 is constructed by excavating the ground, laying the cracked stone 28 and placing concrete 29, and burying the lower end portion of the vertical member 25 in this 300 mm square concrete 29, for example. At this time, it is preferable that the vertical member 25 has its lower end embedded in the lower end of the concrete 29. As a result, the substantially U-shaped frame 27 can be fixedly supported and erected.

  In addition, when connecting the lower end part of each vertical member 25 on the foundations 7 such as soil concrete, the soil concrete is suspended, and the cracked stone 28 is laid and the concrete 29 is cast in the same manner as above. It is preferable that the vertical member 25 is erected firmly by burying the lower end thereof. Accordingly, even when the lower ends of the vertical members 25 are connected to the foundation 7 such as soil concrete, the frame body 27 can be fixedly supported and erected.

Furthermore, as shown in FIGS. 1, 3, and 4, the interposition structure B < b> 2 is a first closing member for closing a gap H on both sides between the frame 27 and the outer wall T < b> 1 of the building body T. 30 and a second closing member 31 for closing a gap H on the upper side between the frame 27 and the outer wall T1 of the building body T.

As shown in FIGS. 1 and 3, the first closing member 30 is formed in a band shape, and is fixed to the side surface of the longitudinal member 25 of the frame body 27 by screwing the one side end portion 30 a side and the other side. The end 30b side is disposed in contact with the outer wall T1 of the building body T. Accordingly, the gap H extending in the vertical direction S < b > 2 between the frame body 27 and the outer wall T < b> 1 of the building body T is closed by the belt-like first closing member 30.

Further, in the present embodiment , the first closing member 30 is formed in a rectangular flat plate shape, is fixed by bringing the one side end 30a side into surface contact with the side surface of the longitudinal member 25, and extends straight to the outer wall T1 side. The first closing material 32 that closes the gap H and the one side end portion 30a side are fixed to the side surface of the longitudinal member 25 with a space therebetween, extend straight to the outer wall T1 side, and the tip side thereof is the first closing material 32. It is comprised with the 2nd blocking material 33 which bend | folds so that the front end side may be pressed and may block the gap H.

The first closing member 30 is not particularly limited in its configuration as long as it can close the gap H extending in the vertical direction S2 between the frame body 27 and the outer wall T1 of the building body T. The other end 30b side may be fixed to the outer wall T1 of the building body T. The first closing member 30 may be an elastic body such as rubber, a metal plate, or the like.

  As shown in FIGS. 1 and 4, the second closing member 31 is formed in a substantially band shape, and is fixed to the upper surface of the cross member 26 of the frame body 27 by screwing the one side end portion 35a side. A frame-side blocking material 35 provided, and an outer-wall-side blocking material 36 that is formed in a substantially band shape and is fixed to the outer wall T1 of the building body T by, for example, screwing one side end portion 36a side. It is configured.

  Further, the second closing member 31 of the present embodiment is disposed so that the other side end portions 35b and 36b of the frame side closing material 35 and the outer wall side closing material 36 are in contact with each other and overlap each other. Further, in the present embodiment, the frame-side closing member 35 is formed by bending the other end 35b upward with respect to the one end 35a. The outer wall side closing material 36 is formed to be bent so that the other side end 36b side is inclined downward with respect to the one side end 36a side. And it arrange | positions so that the other side edge part 36b side of the outer wall side blocking material 36 may overlap with the upper surface side at the other side edge part 35b side of the frame side closing material 35. FIG.

  Further, in the second closing member 31 of this embodiment, the frame side closing material 35 and the outer wall side closing material 36 are provided with engaging claws 37 and 38 on the other side end portions 35b and 36b, respectively. The other end portions 35b and 36b are engaged with each other by the engaging claws 37 and 38 so as to be relatively displaceable. Further, the outer wall side closing material 36 has a bent portion formed as a hinge portion (hinge structure) 39, and is formed so as to be able to absorb displacement by being bent at the hinge portion 39.

The second closing member 31 is not necessarily configured as described above as long as the gap H extending in the lateral direction S1 between the frame body 27 and the outer wall T1 of the building body T can be closed. Good. Further, an elastic body such as rubber or a metal plate may be applied to the second closing member 31.

  Furthermore, in this embodiment, as shown in FIG.3 and FIG.4, in order to improve the external appearance of the building external structure B, the 1st closing member 30 and the 2nd closing member 31 are each coat | covered with the coating | coated member 40. .

  And in the building exterior structure B of this embodiment which consists of the said structure, the clearance gap H is opened between the outer wall T1 of the building main body T, and the U-shaped frame which consists of a pair of vertical member 25 and the horizontal member 26 27, and a pair of vertical members 25 of the frame body 27 are connected to the side ends of the side wall portion 3 of the external construction body B1 and the cross member 26 is connected to the tip end portion (the rafter 17) of the roof portion 2. Build a building exterior structure B such as a room.

  As a result, even if the outer wall T1 of the building body T such as a house is uneven, by installing the frame body 27 with a gap H from the outer wall T1 in advance, the frame body 27 can be attached regardless of the unevenness. It is possible to construct an external structure body B1 that is connected and includes the front wall part 1, the roof part 2, and the side wall part 3.

Further, the side gap H between the frame 27 and the outer wall T1 of the building body T is closed by the first closing member 30, and the upper gap H between the frame 27 and the outer wall T1 of the building body T is set to the second. By closing with the closing member 31, rainwater and outside air can be prevented from entering the interior (indoor) of the external structure body B1.

  Further, for example, even when snow accumulates on the roof portion 2 and a snow load acts on the roof portion 2 or wind pressure acts on the roof portion 2, the end portion of the roof portion 2 (the rafter 17) has a U-shaped frame. Since the rigidity is enhanced by being connected to 27, it is possible to prevent the deflection of the tip portion of the roof portion 2 compared to the conventional case.

  In addition, the first closing member 30 and the second closing member 31 are interposed between the external structure main body B1 and the outer wall T1 of the building main body T instead of the front end portion of the roof portion 2, and snow load or wind pressure acts. Since it is connected to the frame body 27 that is difficult to displace, the gap H provided between the frame body 27 and the outer wall T1 of the building main body T is surely connected to the first closing member 30 even if snow load or wind pressure acts. While being closed by the second closing member 31, this state can be maintained.

  Therefore, according to the building exterior structure B of the present embodiment, it is possible to flexibly cope with the unevenness of the outer wall T1 of the building body T, and it is ensured that the appearance is deteriorated and a gap is generated between the outer wall T1 of the building body T. Can be prevented.

Further, in the building exterior structure B of the present embodiment, the second closing member 31 that closes the gap H between the frame body 27 and the outer wall T1 of the building body T is formed by the frame-side closing material 35 and the outer wall-side closing material 36. The frame body is composed of two members and is arranged so that the other side end portion 35b side of the frame side closing material 35 is overlapped with the upper surface side of the other side end portion 36b side of the outer wall side closing material 36. When a relative displacement occurs between the main body 27 and the building body T, the displacement can be absorbed, and a gap can be prevented more reliably.

  Furthermore, in the building exterior structure B of the present embodiment, the second closing member is composed of two members of the frame side closing material 35 and the outer wall side closing material 36 and the other side end of the frame side closing material 35. 35b side is bent upward, the other side end part 36b side of the outer wall side closing material 36 is bent downward, and the other side end parts 35b, 36b side are overlapped and engaged with each other, thereby being connected to each other. This displacement can be absorbed when a relative displacement occurs between the main body 27 and the building body T, and the occurrence of a gap can be further reliably prevented. For example, as shown in FIG. 4, even if a displacement M of about 10 mm occurs, it can be absorbed.

  Moreover, in the building exterior structure B of this embodiment, since the bending part of the outer wall side closing material 36 was formed as the hinge part 39, the relative displacement arose between the frame 27 and the building main body T. At this time, it is bent at the hinge portion 39 of the bent portion, so that the displacement can be reliably absorbed. Therefore, it becomes possible to more reliably prevent rainwater, snowmelt water, outside air and the like from entering the room due to a gap.

  As mentioned above, although one Embodiment of the building exterior structure concerning this invention was described, this invention is not limited to said one Embodiment, It can change suitably in the range which does not deviate from the meaning.

  For example, in this embodiment, the building exterior structure B has been described as a garden room type building exterior structure. However, the building exterior structure according to the present invention is a side-through type or an open side-through with only a pillar on the front surface. It may be a type of building exterior structure. Moreover, although the front wall part 1 of the external structure main body B1 was comprised with the waist wall part 4 and the lighting wall part 11, it is not necessary to provide the waist wall. That is, the external structure main body according to the present invention only needs to include the front wall part 1, the roof part 2, and the side wall part 3, and there is no need to particularly limit other configurations. And even in such a case, of course, it is possible to obtain the same effect as this embodiment.

  Further, in the present embodiment, the bent portion of the outer wall side closing material 36 of the second closing member 31 is formed as the hinge portion 39, but the bent portion of the frame side closing material 35 may also be used as the hinge portion. The bent portions of the frame side closing material 35 and the outer wall side closing material 36 may be hinge portions.
