Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a roof, and more particularly to a method for installing a roof panel. Also, the present invention relates to a roof construction method capable of minimizing a dimensional error between opposed roof slopes. 2. Description of the Related Art Conventionally, a roof of a building constructed by a panel construction method is constructed as follows. That is, the roof panels are lifted one by one by a crane, and at one roof inclined portion, a connecting girder having a triangular cross section attached to an upper portion of the outer wall panel, a roof cutting panel, and a beam erected between the roof cutting panels. The roof panels are placed one by one on the upper part with a predetermined roof inclination. And every time one roof panel is placed, on the top or beam of the outer wall panel,
After the fixing of one roof panel is completed by fixing with a screw nail or the like, the next roof panel is placed and fixed in the same manner. Thus, after one roof slope is formed, the other roof slope is formed by the same operation.
In addition, the order of installation of the roof panel in the above work,
FIG. 3 shows the reference numerals 1 to 18. [0003] By such a work, the installation of the roof panel is completed, the roof inclined portion is formed, and after the roof portion is constructed, the roof finishing material is applied to the upper surface of the roof panel face material as a finishing process of the roof portion. The roof is waterproofed. However, when the roof panels are installed in the order shown in FIG. 3, one of the roof inclined portions 100 including the roof panels 1 to 9 in FIG.
And the other roof slope 2 composed of roof panels 10 to 18
A large error sometimes occurred in the length in the longitudinal direction of the roof portion from 00. That is, first, the roof panels 1 to 9 are joined and installed in numerical order, and one of the roof inclined portions 100 is formed. Then, the roof panel 10 is attached to the opposite side of the roof panel 9, and then the roof panels 11 to 18 are sequentially joined and installed. When installing the roof panels 10 to 18, the opposite roof panels 1 to 18 are installed. 9 may be slightly deviated at the opposed installation position. In particular, after the last roof panel 9 constituting one roof inclined section 100 is installed, the roof panel 1 constituting the other roof inclined section 200 based on this roof panel 9 is set.
When 0 to 18 are installed, if one of the roof slopes 100 is displaced, the other roof slope 200 is formed based on the shifted roof panel 9 and finally. Specifically, there is a problem that a large displacement may occur between the two inclined portions 100 and 200. [0007] In addition, the installation of the roof finishing material is performed as a finishing process of the roof portion, but the work of mounting the roof finishing material on the upper surface of the roof panel is a cumbersome operation and burdens the operator. This was contrary to the demand for industrial mass production of buildings. Therefore, a roof finishing material can be attached to the upper surface of the face material of the roof panel in a factory in advance. In this case, after the roof panels are joined and installed, the work of attaching the sealing material must be performed to waterproof the joints of the roof panels, and the burden on the operator cannot be reduced. SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned disadvantages of the prior art, and an object of the present invention is to minimize an error in length between opposed roof slopes. Another object of the present invention is to provide a method for constructing a roof, which can omit a work of attaching a roof finishing material on site. [0010] In order to achieve the above object, a roof construction method according to the present invention is a method of joining a plurality of roof panels formed by attaching a face material to a core material assembled in a rectangular shape. The method for constructing a roof, comprising: a roof inclined portion formed as described above; and another roof inclined portion formed by joining a plurality of the roof panels at a position facing the one roof inclined portion in an intersecting direction. Panels are attached to adjacent roof panels

Next, the overlapping portion of the roof panel in a subsequent order to be joined adjacent to the roof panel already installed in the preceding order on the one roof inclined portion side is the anti-overlapping portion of the roof panel in the preceding order. By joining the side end surfaces of the roof panel in contact with each other in a state where they are superimposed on the top surface
The sealing material is tightly polymerized on the roof finishing material on the anti-polymerization side.
And repeating the process. Incidentally, in the present invention, the anti-polymerized portion means a portion where no polymerized portion is formed. According to the roof construction method of the present invention described above, since the roof finishing material is previously attached to the surface of the roof panel face material, the work of attaching the roof finishing material at the construction site is performed. Is no longer necessary. [0013] In addition, since one roof panel has an overlapped portion at a joint end with another adjacent roof panel, this overlapped portion overlaps with a joint end of another roof panel. , So as to close the gap between the joints. Therefore, the waterproof effect of the roof portion can be obtained without performing the work of attaching the roof finishing material to the joint between the roof panels at the site. Next, since the roof construction method according to the present invention is constructed by the above-described steps, after the roof panel is attached to one roof slope, another roof panel is opposed to the other roof slope. Can be attached to Thereby, both roof slopes can be installed with reference to the same side, and as a result, it is possible to minimize the displacement of the roof slopes. In addition, the superposed member is provided by the extension portion.

it can. Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing a roof panel 20 in a roof construction method according to the present invention. The roof panel 20 includes a roof finishing material 41 and a conventional roof panel in which a face material 32 is attached to a core material 31 framed in a rectangular shape.
The overlapping member 42 is attached, and a sealing member 43 is attached to the overlapping surface 42 a of the overlapping member 42. A flat slate is used as the roof finishing material 41, and the roof finishing material 41 is attached to the surface of the face material 32 in a factory in advance. Thereby, industrial mass production can be achieved, and the work of attaching the roof finishing material on site can be omitted. In addition, since the overlapping member 42 is attached to the face member 32 via a roofing (not shown) as described below, the roof finishing material 41 is smaller than the face member 32 by the area of the mounting portion 42b of the overlapping member 42. ing. The overlapping member 42 has a long shape, and has a mounting portion 42b for mounting to a side end of the face member 32 constituting a part of the roof panel 20, and an extending portion extending at a right angle from the mounting portion 42b. The extended portion 42c and the overlapping portion 42d which is perpendicular to the extended portion 42c and deviates from the extended portion 42c to a position facing the mounting portion 42b. The mounting portion 42b is adjacent to the roof finishing material 41 on the surface of the face material 32 via a roofing (not shown) at the side where the roof panel 20 is continuously connected, that is, at the longitudinal end. It is a long plate-shaped part that can be attached. This installation is performed, and a sealing material (not shown) is provided at a joint with the roof finishing material 41, whereby the roof panel 20 according to the present embodiment is completed. Since the overlapping member 42 is formed only on one side end of the roof panel 20, the overlapping portion 42d of the overlapping member 42 of the roof panel 20 to be attached in a later order is provided on the other side end. It is designed to polymerize. The overlapping portion 42d is formed at a position deviated from the mounting portion 42b by the extending portion 42c, and is fixed between the surface of the roof finishing material 41 of the roof panel 20 installed in the first order. An interval is formed. Therefore, it is possible to secure a space for attaching the sealing material 43 in advance on the overlapping surface 42a of the overlapping portion 42d, and to overlap the overlapping portion 42d with the side end portion of the roof finishing material 41 of the roof panel 20 in the preceding order via the sealing material 43. Then, the roof panel 20 can be installed in a later order. By doing so, the sealing material 4
3, the waterproof effect can be sufficiently achieved, and since the sealing member 43 and the overlapping member 42 are attached at the factory, the work of waterproofing on site can be simplified. The roof panel 20 in the present embodiment is configured as described above. Next, the steps of performing the roof construction method according to the present invention using the roof panel 20 will be described with reference to FIG. Will be explained. First, the roof panel 21 is installed on the roof inclined section 100 side, and the roof panel 22 is installed on the opposite roof inclined section 200 side. These are the roof ramps 100, 2
At 00, the roof panel to be installed first is not used, and there is no roof panel in which the overlapping member is to be superimposed first, so that the roof panel is attached to the conventional roof panel without attaching the overlapping member. Will do. When the roof panel 22 is installed, adjustment is made so that the position of the roof panel 21 does not deviate from that of the already installed roof panel 21. Next, the overlapping portion 42d of the overlapping member 42 of the roof panel 23 is overlapped on the side end of the existing roof panel 21, and the roof panel 23 is joined and installed. In addition,
As described above, the sealing member 43 is attached to the overlapping surface 42a of the overlapping portion 42d, so that the overlapping member 42 and the roof panel 21 are in close contact with each other and overlap. Then, similarly, at a position adjacent to the roof panel 22, the overlapping portion 42d is overlapped on the side end of the roof panel 22, and the roof panel 24 is joined and installed. At this time, the position of the roof panel 24 and the position of the opposing roof panel 23 are checked for deviation, and if there is a deviation, adjustment is made so as to eliminate the deviation. Thus, the roof panels 25 to 2
8 is installed, and the roof panel 20 is further installed at a position (not shown) to complete the construction of the roof. According to this roof construction method, both of the opposing roof inclined portions 100 and 200 can be installed on the basis of one side, so that when the roof portion is completed,
It is possible to obtain a roof structure in which there is very little error in the length in the longitudinal direction of the roof portion with the opposed roof inclined portions 100 and 200. The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the invention. For example, in the present embodiment, a flat slate is used as the roof finishing material 41 for a simple configuration, but a corrugated slate or a metal roof finishing material may be used. An existing hook bolt can be used to attach the slate having the waveform to the face material. When using the slate of this waveform,
The slate can be made larger than the face material, and the portion protruding from the face material can be used as the overlapping portion. As described above in detail, according to the roof construction method according to the present invention, the roof finishing material is attached to the surface of the roof panel in advance, so that the The work of attaching the roof finishing material can be omitted, and the burden on the operator can be reduced. Further, since the gap between the joints between the roof panels can be closed by the overlap portion formed on the roof panel, it is possible to prevent rainwater from entering. Also, heavy
