Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to horizontal roofs for houses, etc., in which horizontal roof panels are roofed from the top to the bottom from the rising edge of the roof ridge to the eaves, and to a construction method thereof. be.

[Conventional technology]

In general, when horizontally roofing a roof using face plates made of long metal steel plates, etc., a major challenge is to improve the rain protection at the seams between the face plates and to prevent the face plates from lifting up due to wind pressure. It is becoming.

Conventionally, in the case of a normal roof that is roofed from the bottom to the top, the metal hanger is placed on the ridge side of one metal face plate, as shown in Figure 13 A, B, C, and D. This was done by locking and fixing the bottom part, that is, the bottom part. In addition, because the position where the hanger is fixed is closer to the ridge of the roof than the lower ridge, under strong winds and rain, the fixed position floats up in the direction of the air, which is one of the causes of rain build-up, creating problems in terms of watertight structure. Improvements were expected from at least two aspects: the hanger structure and the hanger fixing position. When doing this type of roofing, first, scaffolding is erected around the roof, and using this scaffolding, hangers are attached to the rafters placed on the main building on the roof support material, and the face plates are moved from the eaves to the ridge. This is done by sequentially connecting and fixing them in a step-by-step manner.

[Problem that the invention seeks to solve]

However, in the case of such conventional horizontal roofs, the face plate is joined from the eaves to the ridge side, that is, from the bottom to the top with the eaves as a reference.
Particularly on roof structures with steep slopes, work is not only extremely difficult and dangerous, but also as construction is carried out in stages, the top of the face plate after construction may be used as a foothold for workers, or Because they are often used as a place to store things, the face plate is inevitably easily damaged, and moreover, it takes a great deal of effort to lift the face plate. Furthermore, in the final stage of construction, the width dimension of the top face plate assembled based on the eaves tends to be incorrect at the ridge rise part of the roof, and the ridge side seam of the top face plate is attached to the ridge rise part. The work of fixing using hanging members is troublesome and requires skill, and if it is a part close to the eaves, there is no problem even if some rain accumulates, but when it comes to roofs, rain is fatal. There is a possibility that it will occur in nearby areas. Also, during construction,
The hanger that fixes each face plate is designed so that the ridge side part of the face plate can be held down by a hook part extending from the ridge side, and the fixed part can be attached to the upper and lower face plates. Since it is off toward the ridge side than the seam joint, the installation strength is low. Therefore, when wind pressure acts on the seam joint of the face plate from the eaves side, the wind blow-through load will be applied upward to the hanging part of the hanger. As a result, the hanger is blown up and easily peels off.
This caused various problems such as the face plate lifting up and becoming one of the causes of rain build-up.

This invention was made under the above circumstances, and its purpose is to improve workability by making it possible to roof from the ridge of the roof to the eaves, that is, from top to bottom. To provide a side-thatched roof and a construction method thereof, which can reliably prevent floating joints of adjacent boards from rising up and sufficiently prevent rain from accumulating.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a horizontal roofing roof in which the horizontal roofing face plates are connected and fixed in successive stages from the ridge rising part of the roof to the eaves, and A hanging member to which the ridge side seam of the uppermost face plate is hung is provided in the part, and the base member inserted into the lower surface of the uppermost face plate latched to the hanging member is placed on the rafter. , the eave side seam of the uppermost face plate is secured to a hanger having a fixing piece that comes into contact with the eave side end face of the base member and projects further toward the eaves than the eave side seam of the uppermost face plate; ,
Fix the hangers on the rafters, connect the eave side seams of the topmost face plate to the ridge side halves of the next level face plate through the hangers, and then connect the face plates, base members, and hangers in series. This is what I did.

The present invention also provides a construction method for horizontal roofing in which horizontal roofing face plates are successively connected and fixed in stages from the ridge rising part of the roof to the eaves, and a hanging member is fixed to the ridge rising part. After latching the ridge side part of the uppermost face plate to the hanging member, insert the base member to the underside of the uppermost face plate and place it on the rafters, and then attach the fixed piece ridge of the hanger. The upright piece standing up from the side edge is brought into contact with the eave side end face of the base member, and the eave side end of the hanger fixing piece is made to protrude toward the eave side beyond the eave side seam of the topmost face plate to fix the above. After fixing the pieces to the rafters, lock the eave side seam of the topmost face plate to the support piece that protrudes toward the eaves from the free end of the hanging piece, and then attach it to the eave side seam of the topmost face plate. This is a construction method in which the ridge side seam of the next stage face plate is hooked and connected, and then the next stage and subsequent face plates are repeatedly and sequentially connected together with the base member and the hanger.

[Effect]

That is, the present invention has the above configuration,
Since the face plate is joined from the rising edge of the ridge to the eaves, that is, from top to bottom, there is no need for scaffolding, and construction can be done without using the top of the face plate as a scaffold, which prevents damage to the face plate and allows construction on steep slopes. It is also possible to easily horizontally lay the face plates on roofs, and since the rising part of the ridge is used as a reference, finishing accuracy can be improved without requiring any skill.

In particular, the hangers are fixed on the rafters by positioning these fixing pieces closer to the eaves than the eave-side seam of the upper face plate, so they are resistant to wind blow-up and the face plate does not float up much. The risk of rain can be significantly reduced.

〔Example〕

Hereinafter, the present invention will be explained in detail based on an illustrated embodiment.

FIG. 1 shows a horizontally roofed roof according to an embodiment of the present invention, which is horizontally roofed by a construction method described later. Reference numeral 1 in FIG. 1 denotes a roof support member. A main house 2 is disposed on the roof support member 1, and a rafter 3 made of a channel member having a C-shaped cross section is installed on the main house 2. Incidentally, the rafters may have an appropriate shape such as a hat-shaped cross section or a multi-stage type. On the rafters 3, horizontally roofed face plates 4 made of metal plates are joined in stages from the main building 21 forming the rising part of the ridge toward the eaves, and between the lower surface of these face plates 4 and the upper surface of the rafters 3. A base member 5 made of wood wool board is interposed on the rafters 3.

As shown in Fig. 2, the horizontal roofing face plate 4 is made of a long steel plate of a predetermined width that has been painted with anti-corrosion baking paint, etc., and is shaped into a central portion along the longitudinal direction using a roll forming machine or the like. It is of a predetermined unit length in which a ridge side bevel 42 is continuously bent on the ridge side edge 4a and an eave side bevel 43 is continuously bent on the eave side edge 4b, leaving the face plate portion 41, The ridge side seam part 42 and the eave side seam part 43 are shaped so that they can be jointed to each other. In addition, the face plate 4 has a second

Furthermore, the fixing piece 81 of the hanger 8 has a structure in which the eaves side end 81a serving as the fixed part protrudes further toward the eaves than the free end 83a of the locking piece 83, and is attached to the rafter 3. The mounting strength is increased.

Next, we will introduce the above-mentioned horizontal roof construction method in the sixth section.
This will be explained with reference to FIGS. 11 to 11.

As shown in FIG. 6, first, the hanging member 6 is fixed to the side wall surface 21a of the ridge rising portion 21 with screws or the like, and then, as shown in FIG.
The ridge side seam portion 42 of the topmost face plate 4 is rolled up and latched. In this state, as shown in FIG. 8, the base member 5 is inserted between the lower surface of the uppermost face plate 4 and the upper surface of the rafter 3 from the eaves side, and the base member 5 is inserted from the eave side end. At the same time, as shown in FIG. 9, the fixing piece 81 of the hanger 8 is positioned and fixed on the rafter 3, and the eave side seam 43 of the uppermost face plate 4 is pressed down and supported.

Further, since changes can be made to the above structure without departing from the spirit and scope of the invention, the above description is merely an example and should not be interpreted in any limiting sense.

The scope of the claims is intended to cover every feature of the invention and all matters that may be omitted due to language problems.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, horizontal roofing face plates can be joined in stages from top to bottom from the rising part of the ridge to the eaves, and the upper and lower face plates adjacent to each other can be joined together in stages. A hanger is provided that is hung so as to press down the seam joint part of the base plate, and through the intervention of the hanger, the base member inserted and placed on the lower surface of the face plate can be locked from the eaves side. Because it has a positioning structure, it is easier to transport the face plate compared to the conventional roofing method that roofs from the bottom to the top from the eaves to the rising edge of the ridge, and there is no need for scaffolding, which prevents damage to the face plate. It is easy to roof steep slopes, and the finish is very beautiful. In addition, it does not require any skill, which improves workability, and it also has excellent effects in that the construction cost is low.

Furthermore, according to the present invention, the fixing piece of the hanger is fixed at a position closer to the eaves than the bulge of the face plate, which eliminates the problem of conventional hangings in which the hanger is fixed at a position closer to the ridge than the bulge. It is much more resistant to wind blowing up compared to a child, and as a result, there is no risk of rainwater entering through the raised parts of the goby part, so a great watertight effect can be expected.
