The schematic structure of the plane structure in the building proposed in this way is shown in FIGS. 4 to 6.

Here, FIG. 4 is a perspective explanatory view schematically showing a partially cut-away schematic structure of the vertically-roofed roof structure in this case, and FIG. 5 is the same as the vertically-roofed roof structure. FIG. 6 is an enlarged cross-sectional view of the joint portion of FIG. 6, and FIG. 6 is a perspective view showing the joint member used for the joint portion in the same manner as shown in FIG.

That is, in the already proposed vertical roofing roof structure shown in FIGS. 4 to 6, reference numeral (61) is a vertical roofing roof plate member (hereinafter referred to as a main member of the vertical roofing surface, which is a single member of the faceplate, , Roof plate members), (71) is a joining member that joins adjacent roof plate members (61), (61) to each other at their respective side edges, and (81) is each joined member. Roof plate member (6

Also here, the left and right pressing portions (83) and (83) bent inward and downward are formed at the presser fixing portions (63) and (63), respectively, and the respective extension end portions ( 85) and (85) are folded back to form engagement recesses (84) and (84) which are fixedly engaged with the left and right engagement edges (77) and (77), respectively. .

In this case, on the main building material (91) of the building, first, arrange a plurality of the joining members (71) at predetermined intervals in the vertical direction from the ridge side to the eaves side. In addition, the attachment part (73) is used to fix and fix it with an appropriate fastener (93), and a wood wool cement plate or the like is placed between the joining members (71), (71). The base plate (92) is laid so as not to create a gap as much as possible.

Then, the face plate supporting portions (75), (7

Material (71)
Is a substitute for a rain gutter that discharges rainwater that infiltrates from the joint to the outside, and in this way, the desired vertical roof can be raised.

[Problems to be Solved by the Invention]

Here, in the case of the already proposed vertical roof structure constructed as described above, the adjacent roof plate members (61), (61)
And a covering member (81) interposed therebetween, a joining member (71) serving as a fixed base for the purlin (91) side.
However, since it is formed into a so-called continuous suspension type, it is not necessary to fix it with another suspension member or the like, and one member can be used for both joining and fixing. It has the practical advantage that it can be done, and the application place and its application form, for example,
Since it is possible to construct a preferable thatched roof structure when it is adopted with a relatively small amount of rainfall or a portion which is not exposed to rainfall, probably with the intention of appearance and decoration. On the other hand, on the other hand, in the case of being used for an ordinary general thatched roof structure, during its construction, the joining member
With respect to each joint (76), (76) of (71), the roof plate members (61), (61) each of the presser fixing portions (63), (63) are simply overlaid, The fact that it is fastened with the fastening screws (94), (94), etc. also caused dust and it was difficult to avoid the following disadvantages.

That is, first, regarding the joining member (71) itself, the mounting portion (73) raised in the widthwise intermediate portion of the board portion (72) aims to completely prevent rain leakage to the side of the main material (91). However, due to the existence of this attachment part (73), if it is firmly fixed to the purlin (91) side by the fastening device (93), the fastening force will be increased. The larger (P ₁ ) is, the easier it is for the entire member to deform, as shown by the chain double-dashed lines in FIGS. 5 and 6, and the joints (76), (76) and the parts that are fastened to the same are secured. The roof plate members (61), (61) have a reaction force (P ₂ ) acting in the presser fixing portions (63), (63) opposite to the joining direction. As a result, the roof plate members (6)
The face plate portions (62) and (62) of 1) and (61) float above the upper surface of the base materials (92) and (92), causing not only a wavy phenomenon on the entire roof surface but also the covering member (81) at the same time. A separation phenomenon occurs between each of the pressing portions (83) and (83), and the most important joining mode is broken, and this gap portion and the fastening portion by the fastening screws (94), (94), etc. From each joint (76), (76) and each presser fixing part (6
3), (63) has the disadvantage that it will leak through the rain,
On the other hand, when the mounting portion (73) reduces the space in the joint member (71) that also functions as a rain gutter and is divided, and a relatively large amount of rainwater flows temporarily, this rainwater However, the deformation of the joining member (71) as described above is caused, for example, by forming a rib portion orthogonal to the longitudinal direction of the joining member (71). Although it can be considered that this can be prevented, it is substantially difficult because the joining member (71) is continuously formed in the longitudinal direction by roll forming or the like using a thin steel plate as a material.

Furthermore, in the case of this vertical thatched roof structure, during the roofing work, the joining member (7) by the fastener (93) to the main material (91) side is used.
In addition to the mounting and fixing of 1), the fixing screws (94), (94), etc. of the presser fixing parts (63), (63) for the joint parts (76), (76) must be fixed and fixed one by one. Since it has to be done, the work itself is troublesome and requires a certain amount of skill, which is very troublesome.

Therefore, the object of the present invention is to improve such problems in the related art, and to perform the work well and effectively so that there is no fear that the face plate single members will leak each other. The object is to provide a surface structure in a building of this kind that can be joined with good properties.

(44) and (44), which are further folded back outward to form edge-bending portions (45) and (45) .The water receiving gutter member (41) is the same as the above roof. It is formed by the same means as the plate member (11).

In this case, the adjacent roof plate members (11), (1
As shown in FIG. 1, with respect to the face plate portions (12) and (12) of 1), by making the connecting surface portion (22) of the joining member (21) slightly lower, One division or change may be given to the appearance, and the roof plate member (11) may be appropriately arranged along the longitudinal direction of its face plate portion (12) as shown in FIG. A step (17) or the like is formed on the surface to give the same effect, and the surface itself cannot be reinforced.

Then, in the case of this embodiment configuration, the roofing of the vertical thatched roof structure is performed as follows.

That is, first, on the main building material (51) of the building, through the first base plate (52) such as a wood wool cement plate and the asphalt-fing (53) on the surface, first, , A plurality of water receiving gutter members (41) are arranged at predetermined intervals at predetermined positions in the vertical direction from the ridge side to the eaves side, and each of these water receiving gutter members (41) is arranged at appropriate positions in the longitudinal direction. Straddle each of the suspension members (31) on the left and right
Both 6) and (36) are fixedly attached to the purlin (51) side by a fitting attachment fastener (54) such as a thin washer.

Here, the water receiving gutter member is thus provided by the suspension member (31).
With the (41) attached and fixed, the water receiving gutter member (41)
The laying part (42) of each of the rising parts (33), (3
Depending on the lower end of (3), the left and right folding parts (44), (4
4) is strongly pressed and held toward the purlin (51) side by the lower surface of each face plate support portion (34), (34), and the left and right folded portions (44), (44) and later Each part of each is a downward space part
The space is housed in (40) and (40), and the upward space (37) in the middle of the suspension member (31) is arranged open.

Then, after the second base material (52) is laid again between the adjacent ones of the respective suspension members (31), (31), each face plate of these suspension members (31) Corresponding roof plate members (11) on the support parts (34), (34) and the second base material (52), respectively.
Is placed, and the backing material (16) on the back side thereof is pressure-welded, and at the same time, the presser plate fixing parts (13), (13) that are opposed to the left and right of the adjacent roof plate members (11), (11) are attached. ) Each locking part (1
4) and (14) are joined to each other, that is, the left and right locking edges (39) and (3) of the suspension member (31) exposed in the upward space (37).
For 9), lock each from the outside (opposing side).

Further, the left and right locking edges (3
9), fitting the joining member (21) from above each locking part (14), (14) in each roof plate member (11, (11) locked to (39), Left and right joints at (21) (24), (24)
Is joined to the left and right facing locking portions (14) and (14), and at the same time, the left and right facing presser fixing portions (13) of the roof plate members (11) and (11) are joined. ), (13)
The left and right pressing parts (23) and (23) of (1) are tightly pressed against each other, and as a result, at each joint, the adjacent roof plate members (11) and (11) do not touch each other. Each locking part facing the
(14), (14) are the left and right locking edges (39), (39) of the suspension member (31).
And the left and right joints (24), (24) of the joint member (21) are firmly joined together in a state of being sandwiched, and in this state, water is stored in the joint and formed into a series in the longitudinal direction. Receiving gutter member
(41) is a rain gutter that discharges rainwater that infiltrates from the joint to the outside, and in this way, it is possible to raise a vertical thatched roof as expected.

Therefore, in the case of the configuration of this embodiment configured as described above, roughly speaking, this is attached and fixed to the water receiving gutter member (41) by the suspension member (31), and the roof plate member. (11) and the joint member (21) are designed so as to have the dual functions of mutual joint engagement at the same time. Therefore, these water receiving gutter members (4
1), the roof plate member (11), and the joining member (21) are independent of each other, and these can be independently acted on the respective purpose groups, and further, they can be directly connected to the outside. Roof plate members (11) and joint members (2
For the mutual joining of 1), no fastening means such as a fastening screw is used, that is, in other words, it is not necessary to make a hole in the fastening relevant part. In contrast to the case of the previously proposed configuration described above, the water receiving gutter member that is independently pressed and held by the suspension member (31) is different.
(41) does not deform as a whole, and at the same time, the roof plate member (1
1) and the joining member (21) are also affected by the mounting and fixing of the suspension member (31) to the main material (51), and the base material (52)
Since it does not float from above, there is no fear of undulating phenomenon on the entire roof surface or rain leakage from each joint, and furthermore, the water receiving trough member (41) has sufficient flow passage. Even if a relatively large amount of rainwater flows temporarily because the cross-sectional area is promised, this rainwater will not overflow.

In addition, in the said embodiment, although the case where this invention was applied to the thatched roof structure was described, other, for example,
It is needless to say that the same action and effect can be obtained by applying it not only to the roof structure by the side-roofing type but also to the inner and outer wall structures.

〔The invention's effect〕

As described above in detail, according to the present invention, at least the face plate portion that extends in the longitudinal direction, the presser fixing portion that is bent obliquely outward and downward at the joints on both sides of the face plate portion, and the end portions of each presser fixing portion are turned inward. Face plate unit members each having a locking portion to be folded back, a connecting surface portion extending in the longitudinal direction, and a pressing portion that is bent obliquely inward downward at both joint portions of the connecting surface portion and is pressed against the presser fixing portion. , Joining members each formed with a joining portion that is folded back to the outside at the end of each pressing portion and joined to the locking portion from the outside, and a rising portion that rises on both sides of the combined substrate portion, each rising portion It is bent outward at the upper end of the part,
A face plate support portion that receives and supports the face plate portion from the back side, a substrate attachment portion that hangs downward at the end of each face plate support portion, and is attached and fixed to the base side, and diagonally inside the upward opening of each rising portion.

Since it is provided with a water receiving gutter member having a side wall portion formed in contact with the back surface side of each face plate support portion, respectively, after laying a laid portion of the water receiving gutter member on the base side, By using a suspension member, the water receiving gutter member is arranged so as to straddle the water receiving gutter member, and the rising portions are pressed by the rising portions to attach and fix the water receiving gutter member to the base side. Can be fixedly held, and the engaging portions of the adjacent face plate single members are engaged with the opposing engaging edges of the suspension member from the outside, and the face plates are supported on the face plate supporting portions. By engaging and joining the joining portions of the joining members to the respective engaging portions of the adjacent face plate single-member members that are opposed and engaged with each other, the respective press-fixing portions are respectively attached. The pressing part of can be pressure-welded. Since the joining member can be independently engaged and fixedly held, the relationship between the attachment and fixation of the water receiving gutter member and the engagement and fixing of the face plate single member and the joining member is broken, and thus the joining surface It is possible to maintain good form and prevent rain from leaking from the joint. As a result, the desired surface structure is formed by combining a face plate single member with a water receiving gutter member on the base side and a joint member. Can be configured very easily and easily with good workability.In addition, a backing material is attached to the back surface of the face plate portion of the face plate single member or the back surface including a part of the presser fixing portion, and further, When interposing a base material between the side surface of the base and the back surface of the face plate unit outside the suspension member, the joining and mounting operations can be ensured to further promote the effect, and the overall structure is also compared. Easy, easy and cheap It is those having the excellent features of the Runado.
