Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in a roofing method using long galvanized iron plates.

Prior Art and Problems There are known galvanized iron roofs in which the waterproofing material is compressed between the lower legs, lower legs, and hangers (for example, Japanese Utility Model Publication No. 57-41296, Japanese Utility Model Application Publication No. 62-11111118, 1986
(Refer to Publication No.-1111819, etc.).

Since the above-mentioned conventional technology uses a hanger that is passed through a hanger,
When compressing the waterproofing material, the three stacked roof panels, the lower deck, lower deck, and through-hanger, had to be bent along their entire length.
It requires a lot of labor, and the hanging ropes are cut out in the valleys of the roof, and the lower legs and lower legs where the hanging ropes are missing are laid down, and the valleys made of galvanized iron plates are replaced with the above-mentioned fallen hanging ropes. It is necessary to form a winding piece with the roof plate and connect the roof plate to the trough, which requires a lot of work and is not as efficient. In addition, since the roof panels are made of three stacked roof panels: the lower deck, the lower deck, and the through-hanging panels, we are bending the roof panels, so if there are a large number of stacked galvanized iron panels, the phenomenon of breakage at the bent portions (cracks may occur and the roof is on the verge of being cut) is also avoided. condition, disconnected condition, etc.) are more likely to occur. This breaking phenomenon occurs when the roof surface of a building
This often occurs when the roof panels are bent along the corner with the standing earthen wall around the roof surface, so construction work is carried out by increasing the radius of the bend in the roof panels to prevent this phenomenon. If this is done, a large triangular space will be formed between the corner and the bent portion of the roof sheet, resulting in insufficient strength of the bent portion of the roof sheet against wind pressure, snow load, etc. In addition, since there is no waterproofing material holding part formed in the berm, which is made up of the lower bezel, the lower bevel, and the threaded hanger, the waterproofing material may leak out during the construction process. However, the grooves were flattened during the construction process, resulting in inadequate retention of the waterproofing material, and there is room for improvement in the waterproofness of the ribs.

The present invention was developed in view of the above circumstances, and can be constructed with less labor, has excellent workability, prevents the occurrence of breakage, has sufficient strength against wind pressure, snow load, etc., and is waterproof. The purpose of this project is to propose a construction method that can produce a tin roof with excellent quality.

Means for Solving the Problems Means taken by the present invention to achieve the above-mentioned object are the use of partial hangers, the formation of retaining grooves for waterproofing material in the lower roof plate, and Combining a partial hanger formed with an upper bent part with a protruding length shorter than the bending width of the inwardly inclined bent part with the lower part of the roof board, such as the lower part of the roof panel, The provided waterproofing material is temporarily fixed and tightened three times to be held in the retaining groove and other parts.

Example This will be explained with reference to FIGS. 2 to 11 of the drawings.

1st Step This step is a construction step for the roof panels used in the construction method of the present invention.

The roof board A is a suitable part on the width side of a long galvanized iron board (for example,
For engaging with the dovetail hanger 14 provided in advance on the elongated roof base material 13 of the building C over the entire length of the central part of the width side, the part biased toward the edge of one longitudinal side, or the edge of the other longitudinal side, etc. The upward engaging portion 3 is formed into a U-shape in cross section, an Ω-shape in cross-section (not shown), or the like.

The roof plate A is formed by bending the entire length of the edge side of one longitudinal side upward to form an upwardly bent part 4, and the entire length of the edge side of the upwardly bending part is directed to the opposite side of the upward engaging part 3. The outwardly inclined bent portion 5 is formed by bending the outwardly inclined bent portion downward, and the entire length of the edge side of the outwardly inclined bent portion is bent downward to form the downward bent portion 6. The entire length of the end edge side of the curved part is slightly bent toward the upwardly bent part 4 side to form the end downwardly bent part 7, thus forming the lower leg 1 having an arcuate cross section. The downward bent portion 7 at the end of the lower bridge 1 is used to make the lower bridge 1 adhere to or bite into the waterproof material 12 of the lower bridge 2 during tightening processes such as the sixth, seventh, and eighth steps. to improve the retention of the waterproof material. The entire length of the other longitudinal edge of the roof plate A is bent upward to form an upwardly bent portion 8, and the entire length of the edge of this upwardly bent portion is bent forward toward the upward engaging portion 3 side. An inwardly inclined bent portion 9 is formed by bending downwardly, and a retaining groove 10 for the waterproof material 11 is formed into a ■-shaped cross section, a U-shaped cross section (not shown), etc. over the entire length of this inwardly inclined bent portion. It is constructed by molding a lower bar 2 having a substantially side-shaped cross section (1-shaped cross section) with improved retention of waterproof material. Thus, in the first step, as shown in the second diagram, the lower part 1,
A roof plate A is constructed in which the lower roof plate 2 and the upward engaging portion 3 are formed parallel to the width direction and have the entire length in the length direction. Waterproof material 1 on the underside of
1 is injected using an appropriate injection means (for example, injection using an automatic injection machine, manual injection, etc.) to form a first waterproof layer, thereby forming the entire roof panel A. The waterproof material 11 is
It is a well-known caulking material that is soft and highly ductile, easily adheres to metal, and does not have water absorption properties.
If the tightening in the process, 8th process etc. is strongly tightened in the process,
It fills all the gaps in the bridge parts, and even if distortion occurs in the lower bridge 1, lower barrier 2, partial hanger B, etc., it is absorbed by the above-mentioned strong tightening, and the waterproof material of the lower bridge 1 and lower barrier 2 is retained. Combined with improved performance, it exhibits excellent waterproof properties (Figure 2).

Second Step This step is a step of applying waterproofing material to the roof panel A.

A waterproof material 12 is attached and provided on the lower surface of an inwardly inclined bent part 9 formed on a lower frame 2 of a roof board A. The second waterproof layer is formed using a well-known sealing material that is highly adhesive but does not exhibit fluidity or water absorption (Figure 3).

3rd process Roofing work starts from this process. Before explaining the process, I would like to introduce the partial hanger B used after this process.
The configuration of is explained.

The partial hanger B includes a horizontal upper bent portion 15 whose protrusion length is shorter than the bending width dimension of the inwardly inclined bent portion 9 of the lower beam 2, and a raised portion 1.
The upper bent part 15 and the lower bent part 18 formed by bending laterally in the opposite direction are configured to have a substantially two-dimensional cross section. The reason why the protruding length of the upper bent portion 15 of the partial hanger B is formed to be shorter than the bending width dimension of the inwardly inclined bent portion 9 of the lower beam 2 is that
Tightening process, 7th process, 8th process, etc. is a process, waterproofing material 1
1 extends from the edge side of the upper bent portion 15 to the upper surface of the inwardly inclined bent portion 9 of the lower ridge 2 and is easily held in the holding groove 10.

Next, the process will be explained.

The roof board A is assembled by engaging the upward engaging portion 3 with the dovetail rope 14 attached to the elongated roof base material 13 provided in advance on the building C.
is placed on the long roof base material 13, a plurality of partial hangers B are arranged at appropriate intervals in the longitudinal direction of the lower roof 2 of the roof board A, and the upper bent part 15 of the hanger is lowered. It is placed on the inwardly inclined bent portion 9 of the armrest 2. The means for arranging the partial hanger B is the rising part 17.
is brought into contact with the upwardly bent portion 8 of the lower lever 2, and the lower bent portion 18
are attached to the building C (more specifically, to the rafters of the building via the elongated roof base material and sheathing boards) and arranged along the longitudinal direction of the sill 2 (FIG. 4).

4th step The lower frame 1 with the waterproof material 11 formed on another roof board A is placed over the lower frame 2 and the partial hangers B placed on the elongated roof base material 13 (FIG. 5).

5th step The downward bent portion 6 and the downward bent portion 7 of the lower end 1 covered in the 4th step are placed at appropriate intervals in the longitudinal direction, and partially towards the waterproof material 12 of the lower rim 2. It is bent and temporarily fixed to the lower beam 2, and a plurality of temporary fixing parts 19 are formed at appropriate intervals in the longitudinal direction. This temporary fixing part 19 allows the waterproof material 11 to extend to the edge side of the upper bent part 15 of the partial hanger B, and from that edge to above the inwardly inclined bent part 9 of the lower beam 2, and extends into the retaining groove. 10 (Figures 6 and 7).

6th step The entire length of the downward bent part 6 and the end downward bent part 7 of the lower bezel 1 that was partially temporarily fixed to the lower berm 2 in the 5th step is
Bend it towards the waterproof material 12 and tighten it firmly to the lower frame 2 for the first time (referred to as the first tightening). This tightening process uses a known tightening machine (not shown) (FIG. 8).

Seventh step: A waterproofing material 16 is adhered to the entire exposed surface of the downwardly bent portion 6 and the downwardly bent portion 7 of the lower end 1, which were tightened in the sixth step, to form a third waterproof layer. , then lower 1
Bend it toward the upward bent part 4 and the upward bent part 8 of the lower bar 2, and tighten it firmly with the second machine of a well-known tightening machine to perform a second tightening (referred to as second tightening). . The waterproofing material 16 used in this step is a well-known sealing material of the same quality as the waterproofing material I2. In addition, the parts of the roof sheet A that are bent and tightened in this step are the outwardly inclined bent portion 5, the downwardly bent portion 6, the downwardly bent end portion 7 of the lower beam 1, and the inwardly inclined bent portion of the lower beam 2. Part 9,
These are the overlapping parts such as the upper bent part 15 of the partial hanger B and the waterproof material 11, 12, and 16. This tightening depends on the process.
The waterproofing material It, 12.16, etc. is evenly packed into the gap, and at the same time, the waterproofing material prevents the holding groove lO from being flattened, and the waterproofing material is held by the holding groove (Fig. 9). , Fig. 1θ).

Eighth Step This step is a finishing tightening step, and a well-known electric tightening machine is used to perform firm tightening (referred to as third tightening) following the seventh step. Through this process, even though the holding groove 10 may be slightly deformed, the groove shape is maintained and the waterproof material 11 is held, and at the same time, the shaped portions such as the outwardly inclined bent portions 5 of the lower ridge 1 are made waterproof. Material 11.1
2.16, etc., and exhibits excellent waterproof properties both in the area where the partial hanger B is installed and the area where it is not installed (Fig. 11).

In this way, the entire process of roofing is completed, and the waterproofing material 11°12
, 16, a dovetailed long galvanized iron roof with three-point waterproofing was completed (Figure 1).

In the embodiment described above, when connecting the roof board A to the valley (not shown) at the valley of the roof by using the partial hanger B,
When roofing is to be done on a part of the roof where the bending part of the roof shingle A is likely to break, etc., the partial hanger B should not be placed in that area, but the partial hanger B should be installed by slightly changing the location. It is possible to set

Effects of the Invention The present invention uses partial hangers such as those on the diagonal, so that only the areas where the hangers are present require some effort, but since there are many areas where there are no partial hangers, it is possible to The bending process can be completed quickly with less labor, and the construction method as a whole can be constructed with less labor. In addition, for areas of the roof where breakage is likely to occur, such as in the valleys of the roof or bent areas of roof plates, it is possible to slightly change the location of the hangers instead of installing partial hangers. This eliminates the hassle of construction work in the valleys of the roof, improving work efficiency, and reduces the radius of the roof plate bends in roof areas where bending of the roof plates is likely to occur. By making it smaller, the space formed between it and the building can be kept to a small triangular space, and a tin roof can be constructed that has sufficient strength against wind pressure, snow loads, etc. Furthermore, a retaining groove for the waterproofing material is formed in the lower part of the roof plate, and an upper bent part with a protruding length shorter than the bending width of the inwardly inclined bent part of the lower part is formed on the upper part of the partial hanger. The bent part is placed on the inwardly inclined bent part of the lower part of the lower part, and the cast material provided at three places such as the lower part of the part is temporarily fastened, and the third tightening is done in the process, including the retaining groove. By holding the roof in place, a highly waterproof galvanized iron roof with three-point waterproofing is constructed, eliminating concerns about rain leaks and roof leaks.
