[0005]

However, the fixing of a parapet, which is generally performed in a conventional manner, often requires a fixing device or the like for fixing the parapet, and this fixing device or the like is required as a separate component. It has to be prepared, which increases the cost, and requires skill in forming the parapet in accordance with the shape of the lower edge of the roof unit. In addition, since the roof unit is placed on two building units before construction, work must be performed from a building unit at a location where it is difficult to work, and a scaffold is formed again for fixing this parapet Need to be performed, and the mounting workability is inferior.

In most cases, the parapet is disposed outside the outer wall, and the parapet is largely affected by wind pressure and the like.
A fixture with high rigidity had to be used, and the appearance of the fixture was often deteriorated due to the increase in the size of the fixture.

Further, since a rain gutter for receiving rainwater or the like flowing down from the roof unit is disposed separately from the roof unit and the parapet along the lower edge of the roof unit, furthermore, the mounting workability and the appearance are further improved. There was also a problem that the quality deteriorated.

[0008] Therefore, an object of the present invention is to provide a parapet disposition structure having good attachment workability and good appearance quality.

[0009]

According to a first aspect of the present invention, there is provided a parapet disposition structure that is bridged between two spaced apart building units. Mounting bolts at the corners of
The parapet is protruded upward from the building unit, and both ends of the parapet are attached to the protruding corners. At both ends of the parapet, insertion holes into which the mounting bolts are inserted are formed, and the parapet is mounted on the building unit. It is characterized by a parapet disposition structure in which a mounting portion is provided.

According to the second aspect of the present invention, the roof unit is bridged between the two building units by mounting bolts projecting upward from the corners of the two separated building units. A parapet arrangement structure in which both ends of the parapet are attached to the protruding corners and are disposed along the lower end of the roof unit, wherein the mounting bolts are inserted into both ends of the parapet. A parapet arrangement structure is provided in which an insertion hole is formed and an attachment portion is provided between the building unit and the roof unit.

Further, according to the third aspect of the present invention, the upper surface of the parapet is provided along the longitudinal direction of the parapet.
3. A parapet arrangement structure according to claim 1, wherein a rain gutter having a length extending between said building units is formed.

[0012]

According to the present invention configured as described above, two building units are separated from each other by using mounting bolts for arranging a roof unit projecting from the corners of the two building units. Since it is installed and bridged between units, there is no need to prepare separate parts for mounting, and it can be installed before mounting the roof unit, eliminating the need to separately form a scaffold . For this reason, the workability of the construction is better than the fixing of the parapet, which is generally performed conventionally.

In addition, since the mounting portions formed at both ends of the parapet are mounted on mounting bolts for arranging the roof unit projecting from the protruding corners, conventionally, the mounting portions are generally mounted on the lower edge of the roof unit. The mounting strength is improved as compared with the ones. Moreover, since this mounting portion is interposed between the building unit and the roof unit, it is pressed against the building unit by the weight of the roof unit,
With the mounting strength further improved, this parapet mounting part is hidden by the building unit and the roof unit,
The appearance quality is also good.

Further, since the rain gutter is formed on the upper surface of the parapet with a length extending in the longitudinal direction of the parapet and extending between the two building units, the construction is completed at the same time by disposing the parapet. Therefore, the workability of construction is better than that of a parapet that is separately provided.

Further, since the rain gutter is formed on the upper surface of the parapet, it is difficult to see from below, and the appearance quality can be improved.

The upper surface plate 5b of the parapet 5 is formed at both ends with insertion holes 7 into which the mounting bolts 4 and 4 are inserted, and the building unit 1 and the roof unit 3 are mounted in the mounted state. A long plate-shaped mounting portion 6 interposed therebetween is protruded from the rear edge toward the building unit 1 side. Then, the parapet 5 is formed by
And is arranged along the lower end 3 a of the roof unit 3.

On the back surface of the parapet end 5f,
Engagement projection 1 formed on the front surface of outer wall material 10 at the corner 2
1 is provided, and a locking projection 11 is inserted into the locked portion 12 and locked when the parapet is placed from above. .

Further, the rain gutter 8 has a length extending along the longitudinal direction of the parapet 5 and extending between the building units 1 and 1. At both end portions 8a of the rain gutter 8, inclined portions 8b, 8b inclined toward the rear of the parapet are formed, respectively. Then, the rain gutter 13 provided on the upper end surfaces of the frame member 14 and the outer wall member 10 of the building unit 1 from the inclined portion 8b through the opening 8c formed in the back plate portion 5c. The rainwater in the rain gutter 8 is configured to flow down.

Next, the operation of the first embodiment will be described. According to the parapet arrangement structure of the first embodiment, first, the mounting bolts 4 and 4 are erected at the protruding corners 2 and 2 of the two building units 1 and 1, which are separated from each other. Are inserted through the mounting bolts 4 and 4 and fixed on the rain gutter 13 on the building unit 1 side.

Next, the parapet 5 is lowered from above so that the insertion holes 7, 7 formed in the mounting portion 6 of the parapet 5 are inserted into the mounting bolts 4, 4. At this time,
Locked part 1 formed on parapet end 5f, 5f back surface
2 and 12 are locked by the locking projections 11 and 11 and the parapet ends 5f and 5f are fixed to the outer wall 10 surface. Since this operation only lowers the parapet 5 from above, for example, an operator can get on the building unit 1 and perform the operation.

The side plates 5d, 5d are
6, the outer wall 10 is fixed to the screw hole 10a. Further, in this state, the mounting portion 6 may be temporarily tightened and fixed to the mounting bolts 4 and 4 with a fixing tool such as a nut.

Then, the roof unit 3 is placed over both the building units 1 and 1 with the mounting portion 6 interposed therebetween, and is fixed to the mounting bolts 4 and 4 with a fixture such as a nut (not shown). Tighten and fix.

As described above, the parapet 5 is attached to the two building units 1 by using the mounting bolts 4 and 4 for arranging the roof units projecting from the corners 2 and 2 of the two building units 1 and 1. , 1 so that there is no need to prepare separate parts for mounting, and it is possible to dispose the roof unit 3 before placing it, eliminating the need to separately form a scaffold. For this reason, the workability of the construction is better than the fixing of the parapet, which is generally performed conventionally.

The mounting holes 6 of the mounting portion 6 formed at both ends of the parapet 5 are used to insert mounting bolts 4 and 4 for arranging the roof unit projecting from the protruding corners 2 and 2. As a result, the mounting strength is improved as compared with a conventional roof unit which is generally mounted on the lower edge 3a or the like. Especially in the case of steel building units,
Since the mounting bolts 4 and 4 are provided on the capital, sufficient strength can be obtained. Moreover, since the mounting portion 6 is interposed between the building units 1 and 1 and the roof unit 3, the weight of the roof unit 3 presses the mounting unit 6 against the building units 1 and 1, thereby further improving the mounting strength.

Further, since the mounting portion 6 of the parapet 5 is interposed between the building unit 1 and the roof unit 3, it is hidden by the building unit 1 and the roof unit 3 so that it cannot be seen from the outside and the appearance quality is low. Good.

The rain gutter 8 is provided on the upper surface of the parapet 5.
Along the longitudinal direction of the parapet 5, both building units 1,
Since it is formed with a length extending over one space, the installation is completed at the same time by disposing the parapet 5. Therefore, the construction workability is better than the parapet 5 that is separately provided.

The rain gutter 8 also receives rainwater flowing down the front wall surface of the roof unit 3 and does not fall down to the ground as it is. Since the rain gutter 8 is formed on the upper surface of the parapet 5, it is difficult to see from below, and the appearance quality can be improved.

The rainwater in the rain gutter 8 is discharged from both ends 8a,
The frame member 1 of the building unit 1 is formed from the inclined portions 8b, 8b formed toward the rear of the parapet 8a, through the openings 8c formed in the back plate 5c.
It flows down to the rain gutter 13 provided on the upper end surface of the outer wall material 4 and the outer wall material 10. The position of the building unit 1 where it flows down to the rain gutter 13 is changed from the inclined portions 8b, 8b inclined toward the rear of the parapet formed at both ends 8a, 8a to the openings formed in the rear plate portion 5c. Since it is performed through 8c, it cannot be seen from the front of the parapet 5 at all. Therefore, the appearance quality is further improved.

In the first embodiment, a long plate-like mounting portion 6 is provided on the parapet 5 so as to protrude from the rear edge toward the building unit 1. However, the present invention is not limited to this. At the both ends of the parapet 5, insertion holes 7, 7 into which the mounting bolts 4, 4 are inserted are formed between the building units 1, 1 and the roof unit 3, for example. If it is a mounting part interposed in
It goes without saying that the mounting portion may have any shape.

In the first embodiment, the parapet 5
The roof unit 3 is placed above the
However, the present invention is not limited to this. For example, two building units 1, 1 separated from each other, such as a combination pattern having no roof unit 3 or the like.
It goes without saying that any parapet 5 can be used as long as the parapet 5 is bridged between them.

[0035]

As described above, according to the present invention, the parapets are separated from each other by using the mounting bolts for arranging the roof units projecting from the corners of the two building units. Since it is arranged between two building units, there is no need to prepare separate parts for mounting, and it is possible to arrange before the roof unit is placed, and it is not necessary to separately form a scaffold. For this reason, the workability of the construction is better than the fixing of the parapet, which is generally performed conventionally.

Further, since the mounting portions formed at both ends of the parapet are interposed between the building unit and the roof unit, the mounting rigidity is improved. In particular, in the case of a steel-frame-based building unit, mounting bolts are provided on the capitals, and sufficient strength can be obtained. In addition, the parapet attachment portion is hidden by the building unit and the roof unit, and has a good appearance quality.

Further, since the rain gutter is formed on the upper surface of the parapet so as to extend in the longitudinal direction of the parapet and to extend between the two building units, the construction is completed simultaneously by disposing the parapet. Therefore, the workability of construction is better than that of the arrangement separately provided with the parapet.

Further, since the rain gutter is formed on the upper surface of the parapet, it has a practically useful effect that it is difficult to be seen from below and the appearance quality can be improved.
