Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit type rooftop structure and its mounting method, in which rainwater flows smoothly, has good durability, is easy to carry out, and the number of working days and working effort are small.

[0002]

2. Description of the Related Art Conventionally, on the roof of a building, a sheet-shaped heat insulating material or roofing material is adhered to a building concrete with an adhesive to form an inner layer, and the outer layer above it is exposed to sunlight or external impact. In order to prevent the destruction due to the above, color tin, a vinyl chloride steel plate, a copper plate, a stainless metal plate, etc. were attached. However, when this outer layer is a PVC steel plate, etc., it is often damaged by holes, cracks, etc. due to sudden flying objects from the outside or colliding objects with sharp edges. Even if it is a metal plate, it cannot follow the shrinkage of the concrete structure of the building over time and the expansion and contraction of the outer layer itself, causing cracks and deflections,
It has been unavoidable that rainwater enters the inside of the concrete structure from the damaged place of the rooftop structure and causes water leakage inside the concrete structure. The use of a stainless metal plate as the outer layer is ideal in terms of ease of implementation, durability, strength, and cost, but stainless steel has a higher coefficient of thermal expansion than copper, iron, etc. Easy to get
Water leakage into the room due to cracks and flexures was a problem when using a stainless metal plate.

Further, a method of welding a plurality of stainless metal plates as a rooftop structure to form an expansion structure is known from Japanese Patent No. 568725. According to this structure, expansion and contraction of stainless steel and building concrete are absorbed, so that cracks and flexure are less likely to occur, which is ideal. However, in this structure, since all the joints are made by the seam welding method, only the part where the seam welding machine is inserted can be welded. Also, in order to confirm whether or not the welding was done by this welding method, the stainless metal which should have been welded It was necessary to apply a force in the direction of peeling again between the plates, which was a problem in the implementation process.

According to the conventional rooftop structure, as shown in FIG.
As shown in FIGS. 13 and 14, rainwater flowed in the direction of ↓ in the figure because the joint 27 between the roof and the gutter and the part 28 corresponding to the gutter had a slight rise. That is, the rainwater did not flow smoothly to the drainage port 26 and became slow or stagnant on the way. Therefore, it has been expected to develop a rooftop structure in which the outer layer deteriorates or swells due to residual water and rainwater does not rise anywhere up to the drainage port.

Further, when a sheet-shaped heat insulating material or roofing material is adhered onto building concrete, when the building concrete is being struck, irregularities are generated on the surface due to debris in the concrete and the roof slope is also Since it has not been obtained, it is necessary to smooth the surface once, take a gradient, and wait for the adhesive to dry for application. Since this work depends on the weather, it takes days, and improvements were expected.

[0006]

When the conventional rooftop structures shown above are used, the rooftop structure does not sufficiently respond to the contraction of the concrete structure of the building due to aging and the contraction of the metal flat plate itself. In addition to the deformation of structures such as bending, rising, and waviness, cracks and peeling of the joints of metal flat plates sometimes occurred. Even in the expansion structure of the stainless steel flat plate, which is a structure capable of solving this problem, the welding method is a seam welding method, so that there is a problem in the implementation stage. In addition, rainwater collected on the slope of the roof did not flow smoothly due to the rise of the joint surface with the gutter having the drainage port and the rise of the part corresponding to the gutter itself. Furthermore, when a sheet-shaped heat insulating material or moistureproof material is bonded between the building concrete and the stainless metal plate as the outer layer, the conventional method requires useless labor and days.

The problem to be solved by the present invention is to enable smooth movement of rainwater to the drainage port, and also to cope with contraction of concrete structures of buildings due to aging and expansion and contraction of stainless steel itself, which is easy to implement. It is to obtain a rooftop structure and a method of mounting the rooftop structure that require only a few days.

[0008]

Means for Solving the Problems In order to solve the above problems, the present inventor has conducted various studies and completed the following inventions. In the present invention, first, the concrete is poured into the roof of the building, and then the crosspiece member is arranged on the building concrete which has been dried to some extent. This crosspiece member is made by bending a stainless steel flat bar-shaped metal plate into a dogleg shape, and a long bar-shaped crosspiece having a dogleg-shaped cross section and a rectangular crosspiece stopper welded to the crosspiece at regular intervals. It consists of ingredients. This catch member is an anchor that is fixed to building concrete,
At this time, the receiving bar is sloped at the anchor driving depth, and this slope becomes the roof slope.

Further, another stainless flat plate is bent into a box shape having one diagonal side at each lower corner to form a bent stainless plate, and a plurality of flat stainless plates are produced. Furthermore, on the hypotenuse of the lower corner, a sliding claw bracket for attaching the bent stainless plate to the building is welded. Then, the plurality of bent stainless steel plates are joined together by an argon welding method. At this time, these bent stainless steel plates,
The hypotenuses of the lower corners of adjacent objects create gaps that do not join. Then, a mounting body for slidably attaching the stainless metal plate to the concrete of the building is provided in this gap. This mounting body is composed of the slide type claw receiving device and the claw device fixed to the receiving bar. The slide type claw receiving device forms a gap between the bent stainless plate and the bent stainless plate, and the Z type attachment claw is engaged therewith, so that the bent stainless plate and the building are slidably joined together. Since this part is slidable, the expansion and contraction of the stainless metal flat plate in the vertical and horizontal directions can be absorbed.

The bent stainless steel plates joined as described above are regarded as one rooftop structure unit when they have a certain size that can be carried on the roof.
Then, the plurality of rooftop structure units are further joined by an expansion body. This expansion body is
The expansion formed by bending one stainless plate is fitted into the bent part of one end of the bent stainless plate and fixed with a screw. The inside of this expansion body becomes hollow, and the shrinkage of the entire rooftop structure unit is absorbed. It goes without saying that the size and shape of one rooftop structure unit depends on the size and shape of the entire roof.

[0011]

EXAMPLE An example of the present invention will be described with reference to FIGS. Building concrete is poured into the rooftop,
After being dried to some extent, as shown in FIG. 2, the receiving bars 11 previously welded by the argon welding method at regular intervals are used to form the receiving bars 11 as shown in FIG.
Pass the entire width of the roof on top. By doing so, it can also work immediately on this受桟11. Further, as shown in FIGS. 2 and 9, the receiving bar 11 is fixed to the building concrete by the anchor 14 via the beam stopper 12. At this time, depending on the driving depth of the anchor 14,
The receiving bar 11 is sloped, which will be the roof's slope when the roof is subsequently mounted on it. The slope is adjusted by the driving depth of the anchor 14 while the roof is attached later.

On the other hand, as shown in FIG. 3, a stainless metal plate is bent so as to have a joint surface inclined portion 6 . This
As a result, the stainless metal plate becomes the joint inclined part.
Upright surface that joins inclined surfaces and other stainless metal plates
The bent stainless plate 1 has This stainless metal plate has a thickness of about 1.5 in consideration of material cost and strength.
Millimeters are preferable. Further, the slidable claw receiving member 15 is welded to the joining surface inclined portion 6 at one place to several places depending on the vertical width of the roof.

Several to several tens of the bent stainless steel plates 1 are prepared according to the width of the roof, and the bent stainless steel plates 1 are joined as shown in FIGS. At this time, the bent stainless steel plate 1 and the bent stainless steel plate 2 adjacent to each other are welded by the argon welding method. However, as shown in FIGS. 4 and 5, since these stainless steel bent plates are bent, only a part of them is joined. Thus, the joint surface inclined portion 6 is not joined to form the gap 7. Then, the stainless bent plate 1 is attached to the receiving bar 11 by the attachment body 8 in the gap 7. As shown in FIGS. 6, 7 and 8, the attachment body 8 includes a slide type claw receiver 15 fixedly welded to the joint surface inclined portion 6 and an attachment body screw 17 on the receiving bar 11.
And a mounting claw 16 fixed by. Mounting claw 1
6 has a Z-shaped bent shape, and as shown in FIG.
The Z-shaped head is inserted into the gap formed by the sliding claw receiving device 15 and the bent stainless plate 1. By the slide type configuration of this part,
It is possible to flexibly expand and contract the stainless steel plate in the vertical and horizontal directions.

Further, as shown in FIG. 5, when the bent stainless steel plates 1, 2 etc. and the gutter 3 are joined, the rising of the joining surface is caused only by the bent stainless steel plates 1, 2, etc. It exists and does not exist in the joint surface with the gutter 3, that is, in the joint portion in the lateral direction. Therefore, the water flows in the direction of ↓ in FIG. 5, smoothly moves to the gutter 3, and reaches the drain port 26.

The joint with the gutter 3 in this case is as shown in FIG. That is, a stainless steel plate different from the bent stainless steel plates 1 and 2 is bent to form a trough 3, and this stainless steel plate is formed on the back side of the lower end of the roof formed by the bent stainless steel plates 1 and 2. Weld with the argon welding method. At this time, the height of the trough 3 is changed by bending the trough 3 so that the trough 3 is inclined.

A bent stainless steel plate 1 is formed by the method described above.
When 2 etc. are joined and this becomes about 100 square meters in size, as shown in FIG. 10, the one obtained by joining the bent stainless steel plates as one roof structure unit 18,
Further, the unit joining portions 19, 20, 21 of the plurality of rooftop structure units 18 are joined by the expansion body 22 as shown in FIG. Expansion body 22
Is constructed by joining an expansion 23, which is formed by bending a single stainless steel plate, to a portion, which is formed by bending the end portion of the folded stainless steel plate that forms the roof, with a unit joining screw 24. Expansion 22
The inside of the unit becomes the unit joint space 25, and the presence of this space corresponds to the expansion and contraction of the entire rooftop structure unit 18 to some extent.

In all the drawings, the portion indicated by D is formed by the argon welding method. According to the argon welding method, since the electrode for welding is about the size of the thumb, it is possible to weld anywhere in the part where this electrode enters, and moreover, it is possible to confirm the quality of welding while welding.

[0018]

According to the present invention, it becomes possible to walk on a building in a short time after inflowing building concrete,
Since it is not necessary to wait for the concrete to dry completely before the next work, the number of working days can be reduced. Further, the slope of the cross member also determines the slope of the roof, which facilitates the implementation. In addition, since there is no joint that rises in the direction parallel to the roof gutter, water due to rainfall and snow flows smoothly. In addition, the contraction of the stainless metal plate and the contraction of the concrete of the building are caused by the structure of the mounting body, expansion, etc.
Since it is absorbed, the roof structure will not be bent, lifted up, deformed such as wavy, and cracks and peeling of the joint portion of the metal flat plates will not occur.
