Description

Description: TECHNICAL FIELD The present invention relates to a roofing method using a long roof plate and an improvement in a roof structure.

(Prior Art and Problems) There is known a galvanized iron roof in which a waterproof material is pressed by upper and lower halves and suspensions (for example, Japanese Utility Model Publication No. 57-41296 and Japanese Utility Model Publication No. 62-118818, (See Japanese Utility Model Publication No. 62-118819, etc.).

In the above-mentioned conventional technique, since the suspension is used, when the waterproof material is pressed down, the roof plate in which the three upper sheaves, the lower sheaves and the through suspension are stacked must be bent over the entire length. However, it requires a lot of labor, and cuts through the suspension hooks in the roof valleys, and lays the upper and lower halves of the parts where the suspensions have disappeared side by side. The roof and the roof plate must be connected to the trough material by constructing a coil and a roof part, which requires time and effort for the construction work, resulting in poor workability.

In addition, since the roof plate, which is a stack of three upper and lower halves, and a suspension hook, is bent, the phenomenon of breakage of the bent part (cracking and cutting that tends to occur when the number of stacked tin plates is large) Dimensional condition, cut condition, etc.) are likely to occur. This breaking phenomenon often occurs when the roof plate is bent along the corner between the roof surface of the building and the rising wall around the roof surface, so in order to prevent the breaking phenomenon, Construction work is done with a large radius, but if this is done, a large triangular space will be formed between the above-mentioned corner and the bent part of the roof plate, and the strength of the bent part of the roof plate against wind pressure and snow load will be insufficient. Will be enough. And, since the waterproof material holding part is not formed in the mouth part composed of the upper garment, the lower garment, and the through suspension, the waterproof material may flow out during the construction process, and the recessed groove part may be formed on the through suspension. Some of them were formed, but since the recessed grooves deform flat during the construction process, the waterproof material is insufficiently held, and there is room for improvement in the waterproof property of the fender.

The present invention has been made in view of such circumstances, can be constructed with a small amount of labor, and is excellent in workability, has sufficient strength against wind pressure, snow load, etc. by preventing occurrence of breakage phenomenon, and is waterproof. The purpose is to propose a construction method and roof structure that can provide a long roof with excellent performance.

(Example) An explanation will be given with reference to FIGS. 2 to 11 of the drawings.

The roof plate A is a long roof of the building C in advance over the entire length of an appropriate portion on the width side of the long galvanized iron plate (for example, a center portion on the width side, a portion deviated to the longitudinal one side edge side or the longitudinal other side edge side). The upward engaging portion 3 for engaging the dovetail suspension 14 provided on the base material 13 is formed by forming an inverted U-shaped section, an Ω-shaped section (not shown) or the like.

The roof plate A is formed by bending up the entire length of both side edges in the longitudinal direction of the long galvanized iron plate to form the upright portions 4 and 8, and one of the upright portions 4 is extended outward (the above-mentioned upward direction). The outward bending portion 5 is formed by obliquely bending forward and downward toward the side opposite to the engaging portion 3), and the entire length of the edge of the outward bending portion 5 is bent downward to bend downward. The portion 6 is formed, and the entire length of the edge of the downward bent portion 6 is slightly bent toward the inside to form the downward bent end portion 7 to form the upper mouth 1. Standing part 8
Is bent toward the inside (upward engaging portion 3 side) toward the front and downward to form an inward bent portion 9, and the entire inward bent portion 9 will be described later. As described above, the waterproof material holding groove 10 for holding the first waterproof material 11 expanded by the fastening and preventing the waterproof material 11 from being scattered is recessed into a V-shaped section and a U-shaped section (not shown). To form the lower dent 2, and the first waterproof material 11 is applied to the lower surface of the outward bent portion 5 of the upper dent 1 by an appropriate injection means (for example, injection by an automatic injection machine or injection by hand). It is provided by injecting it, and further, a second waterproof material 12 is attached and provided on the lower surface of the inwardly bent portion 9 of the lower casing 2.

The first waterproof material 11 is a well-known caulking material that is soft and has a good spreadability, easily adheres to metal, and does not have water absorption property. Moreover, with the above-mentioned strong tightening, even if the upper and lower doors 1 and 2 and the partial suspension B described later are distorted, they are absorbed and excellent waterproofness is exhibited.

The second waterproof material 12 is a well-known sealing material that is rich in adhesiveness but does not exhibit fluidity and water absorption (third embodiment).
Figure).

Further, the downwardly bent end portion 7 of the upper dent 1 is for allowing the upper dent 1 to be brought into close contact with or dig into the second waterproof member 12 of the lower dent 2, and the holding property of the second waterproof member 12 is maintained. Improve.

Next, the partial suspension B used in the main roof structure will be described.

The partial suspension B is overlapped on the upper surface of the lower dent 2 formed to have a protruding length shorter than the bending width dimension of the inward bent portion 9 of the lower dent 2, and the lateral direction for locking the portion. Upper locking portion 15, a lower bent portion 18 that is bent and formed laterally in a direction opposite to the upper locking portion 15 and is nailed to the roof base material 13, and the upper locking portion 15
And an upright portion 17 connecting the lower bent portion 18 to each other to have a substantially Z-shaped cross section.

The protruding length of the upper locking portion 15 of the partial suspension B is formed to be shorter than the bending width dimension of the inward bending portion 9 of the lower dent 2.
The first waterproof material 11 spreads from the end edge side of the upper locking portion 15 to the upper surface of the inward bent portion 9 of the lower door 2 by the fastening, and the groove of the waterproof material holding groove 10 on the upper surface of the inward bent portion 9 This is because it is easier to be retained by penetrating inside.

Then, a method of constructing a long roof using the above roof plate A and partial suspension B will be described.

The roof board A is placed on the roof base material 13 by engaging the upward engaging portion 3 with the dovetail suspension 14 installed on the roof base material 13 previously provided in the building C. It is arranged on a plurality of partial suspensions B at appropriate intervals in the longitudinal direction on the lower casing 2, and the upper side engaging portions 15 of the partial suspensions B are arranged so as to overlap with the inward bent portions 9 of the lower casing 2. To do. The means for arranging the partial suspension B is such that the rising portion 17 is brought into contact with the rising portion 8 of the lower sill 2 and the lower bending portion 18 is connected to the building C (specifically, the roof base material and the ground plate are used to interpose the building Rafter)
It is fixed to the roof base material 13 by fixing it to the roof by fixing it to the roof (13)
Figure).

Next, the upper roof 1 of the adjacent roofing board A is put on the lower roof 2 fixedly placed on the roof base material 13 from above the partial suspension B (5th embodiment).
Figure).

Then, the downwardly bent portion 6 and the downwardly bent end portion 7 of the upper treat 1 are partially bent toward the second waterproof material 12 on the lower surface of the lower treat 2 at appropriate intervals in the longitudinal direction. Temporarily fixed to the lower den 2 and a plurality of temporarily fixed portions 19 are formed at appropriate intervals in the longitudinal direction.
By the work of this temporary fixing portion 19, the first waterproof material 11 of the upper one is clamped by the outward bent portion 5 of the upper one and the inward bent portion 9 of the lower one 2, so that the partial suspension B is locked on the upper side. While extending to the edge side of the part 15, extending from the edge to above the inward bent part 9 of the lower dent 2, it penetrates into the waterproof material holding groove 10 formed on the upper surface of the inward bent part 9. And pushed in (Figs. 6 and 7).

Then, the entire length of the downwardly bent portion 6 and the downwardly bent end portion 7 of the upper treat 1 partially temporarily fixed to the lower treat 2 is set to the second waterproof material of the lower treat 2.
Bend toward 12, and firmly tighten to the lower garment 2 for the first tightening (referred to as the first tightening). For this tightening process, the first machine in the well-known unshown fastener machines (not shown) is used.
Figure).

Further, the third waterproof material 16 is attached and provided on the entire exposed surface of the downwardly bent portion 6 and the downwardly bent end portion 7 of the upper mouth 1 tightened in the above-mentioned step, and thereafter, outwardly of the upper mouthpiece 1. Folded part 5, downward bent part 6
And the downwardly bent end portion 7 and the inwardly bent portion 9, the partial suspender B, the first waterproof material 11, and the second waterproof material 1 of the lower dent 2 sandwiched therebetween.
2 and the third waterproof material 16 are integrally bent toward the upright portion 8 of the lower casing 2, and are firmly tightened by the second machine in the well-known fastener machine to perform the second tightening (referred to as the second tightening). To do.

By this tightening process, each waterproof material 11, 12, 16 is evenly filled in the gap, and at the same time, by the second waterproof material 12,
Further, due to the second waterproof material 12 and the third waterproof material 16, the lower surface side of the waterproof material holding groove 10 formed in the inward bent portion 9 buffers the clamping force at the time of tightening, and the waterproof material holding groove 10 is formed. The flat deformation is prevented and the first waterproof material 11 is prevented from being scattered (FIGS. 9 and 10).

The third waterproof material 16 used in this step is a known sealing material of the same quality as the second waterproof material 12.

Then, the electric fastening machine in the well-known fastening machine is used, and subsequently, tight fastening (referred to as third fastening) is performed. After this step, even if the waterproof material holding groove 10 is deformed to some extent, the groove shape is maintained and the first waterproof material 11 is held in the groove, and at the same time, the outward bent portion 5 of the upper treat 1 and the like. The overlapping portions of the above-mentioned parts are in close contact with or bite into the respective waterproof materials 11, 12, 16 and exhibit excellent waterproofness both in the disposition part and the disposition part of the partial suspension B (Fig. 11).

Thus, the whole process for the roofing of the long roof is completed,
A long galvanized iron roof that is waterproofed to three points with each waterproof material 11, 12, 16 is completed (Fig. 1).

In the embodiment described above, the use of the partial suspension B
When the roof plate A is maintained as a trough material (not shown) in the valley part of the roof, and when the roof part is easily roofed at the bent part of the roof plate A, a partial suspension member is applied to the part. It is possible to dispose the partial suspension B by slightly disposing the disposing site without disposing.

(Effect of the invention) Since the invention is constructed as described above,
As a result, since the number of parts in which the partial suspension is not present increases, it becomes possible to finish the bending process of the part with a small amount of labor, and the construction method as a whole can be constructed with a small amount of labor.

And, in the valley part of the roof, the roof part where the breakage phenomenon is likely to occur in the bent part of the roof plate, etc.
It becomes possible to arrange the suspension installation part slightly different,
This saves time and effort for construction work in the valley of the roof, improves workability, and reduces the radius of the bent part of the roof plate at the roof part where the bent part of the roof plate easily breaks. The space formed with the building can be limited to a small triangular space, and a long roof having sufficient strength against wind pressure and snow load can be configured.

Further, according to claim 2, the second waterproof material interposed on the lower surface side of the inward bent portion of the lower roof roof cushioning buffers the clamping force applied to the inward bent portion at the time of tightening, and The waterproof material holding groove formed on the upper surface is prevented from being deformed flat, and the first waterproof material spread and held in the waterproof material holding groove is prevented from being scattered. Therefore, a long roof having excellent waterproof property is constructed, and the fear of rain leak, spill leak, etc. is eliminated.

Further, according to claim 3, the clamping force applied to the inwardly bent portion of the lower garment at the time of tightening is buffered by the third waterproofing material together with the second waterproofing material, and as a result, it is formed on the upper surface of the inwardly bent portion. The shape retention of the waterproof material retaining groove is further enhanced.
Therefore, the fear of rain leaks, spillage, etc. is eliminated, and a long roof superior in waterproofness is constructed.
