Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a roof tile which is integrally formed into a single piece in a state where small pieces of running water of several rows and several rows are appropriately laid together and a roof tile using the roof tile. It relates to the laying method that can be laid every time.

[Conventional technology]

Conventionally, for example, in order to tile a roof with a gable, a ridge, etc., in the same bank, a roof tile with an edge at one end is used as a roof start for the roof, and most of the roof is substantially rectangular. The roofing length is adjusted by mixing and using a roof tile or, if necessary, a rectangular adjustment roof tile shorter than this roof tile, and adjacent roof tiles are used for laying along with the roof tile for rain. Laying between each other via the roofing section,
Moreover, the end of the roof is sewn through the roofing section using several types of tiles toward the upper ridge part by using sleeve end tiles with edges, and further to the ridge part at the top of the roof The laying work is being done by connecting ridged roof tiles. In this case, the tiles are laid in various patterns such as a lattice as a roofing pattern of the entire roof or a staggered pattern in order to finish the appearance beautifully.

In addition to the materials used to form the roof tiles, other than those that fire clay like this tile, the cement was compressed and cured and solidified like thick cement tiles, and the asbestos was used like slate tiles Some were formed using small pieces made of a thin metal plate such as copper, aluminum, stainless steel or the like, such as a color iron plate.

[Problems to be solved by the invention]

However, in each of the above conventional tiles, several types of tiles (ground tiles) each having a predetermined size and formed in a substantially rectangular plane are manufactured one by one, and the tiles are adjacent to each other in the left-right direction. Since the tiles located in the ascending or descending direction are laid one by one on the baseboard one by one through the roofing portion arranged so that they overlap with each other, and via the roofing overlap portion,
A lot of cost and labor are required for the production cost and the laying work.

In addition, among the above-mentioned conventional roof tiles, flat tiles, which are particularly compression-molded with cement or slate, cannot be reinforced because of the thickness in order to guarantee the strength. As a result, cracking and cracking sometimes occurred due to the inability to bear the weight. Since this is a structure in which the tiles are superposed particularly at the roofing portions of the tiles adjacent to each other on the left and right sides, the only option is to reduce the wall thickness. Simply increasing the thickness of the tiles to address this and strengthening the structure would increase the weight of a single tile per unit area, and would also be necessary when laying roof tiles on a roof. With dangerous work at high places, and inconvenient handling and transportation, the cost was high. Moreover, when the roof tile is laid and constructed on the roof, the thickness of the roof tile is increased due to the overlapping of the roofing parts. In addition, since the size of each tile body is small and the laying area is small, the efficiency of laying roof tiles to be laid at one time is poor and inefficient.

In addition, since the tiles are laid from the eaves to the upper ridge, they are laid in such a way that the roof area has a slope if the size of each tile is simply increased to increase the laying area. A continuous space corresponding to the thickness of the tile bodies between the field board and the back surface of each tile body on which the upper edge and the lower edge are vertically laid on the field board The overall width of the tiles is wide, the range of the load received by the worker when riding on the top surface of the tiles is wide, and the measures against cracks and chips on the tile body have not been sufficient enough to withstand the weight of the weight.

In addition, when forming a single piece of tile using cement or slate, the tile may be distorted or warped when the tile is transported after compression or when the tile is cured. However, it was not suitable for mass production.

Therefore, the present invention provides a unit which does not increase the weight even if a small piece of flowing water destined for several sheets is formed integrally in a suitable number of rows and columns so that the laying area can be efficiently laid by a single laying. By reducing the weight per area, transportation and handling are facilitated, and roofing work can be performed safely and efficiently. In addition, the structure is robust, but the weight is reduced. It is an object of the present invention to provide a roof tile suitable for mass production, which can prevent cracking and chipping even when the weight is stepped on and does not cause distortion or warpage during molding, and is suitable for mass production and a method of laying the roof tile.

[Means for solving the problem]

The present invention has been made in view of the above-mentioned point, and the roofing portion is provided in a substantially symmetrical manner on the right and left front and back surfaces. In the roof tile which is integrally formed by laterally displacing the flowing water piece portion and the descending flowing water piece portion, peripheral reinforcing ribs are provided on the rear surface of the tile main body in up, down, left and right directions, and in the inner region of the peripheral reinforcing ribs. The horizontally flowing roofing section that vertically divides the back surface of the tile body into the ascending running water piece section and the descending running water piece section, and a plurality of reinforcing ribs vertically provided in a branched shape from the roofing polymerization section,
A means is employed in which a recess is formed in an inner area surrounded by the peripheral reinforcing rib, the overlapping overlapped portion, and the reinforcing rib.

Further, the present invention also provides a roof tile body having a roofing portion provided substantially symmetrically on the left and right front and back surfaces, appropriately dividing the surface of the tile body into several rows and several rows of running water pieces, and ascending and descending running water pieces. In the roof tile laying method that is integrally formed by displacing left and right,
Peripheral reinforcing ribs are provided on the back surface of the tile main body in the upper, lower, left and right directions, and the inner surface of the peripheral reinforcing rib is divided vertically into the ascending flowing water piece portion and the descending flowing water piece portion. A plurality of reinforcing ribs are provided in a longitudinally branched shape from the horizontally overlapping overlapping portion and the overlapping overlapping portion, and a concave is formed in an inner region surrounded by the peripheral reinforcing rib, the overlapping overlapping portion, and the reinforcing rib. A peripheral reinforcing rib provided on the upper edge of the roof tile in which the tile body is formed thin and the roof main body is formed thinly is placed on the upper surface of the roofing base plate and provided on the lower edge. A means is adopted in which the peripheral reinforcing ribs are attached and laid at one time by being laid on the floor board via the upper edge of the lower tile main body which is overlapped and arranged downward.

[Action]

Since a plurality of small pieces of running water were integrally formed in several rows and columns as appropriate, for example, when roof tiles are gabled on a gabled roof, first, for example, by overlapping the symmetrically provided roofing parts, A tile body having running water pieces corresponding to the tile body is laid at once in several rows and several columns from a lower edge of a roof base plate via a roofing material. Next, the lower edge of the flowing water piece located in the lower row of the new tile body to the desired width from the upper surface of the upper edge of the running water piece in several rows located in the upper row of the already-roofed tile body is sequentially laid to the ridge. For example, they are laid in a zigzag pattern.

At the time of roofing, a peripheral reinforcing rib is provided on the back side of the tile body at the upper, lower, left and right sides, and an inner side of the peripheral reinforcing rib is a horizontally long roof that separates an ascending flowing water piece and a descending flowing water piece. Since the reinforcing ribs are provided vertically from the overlap portion and the roof overlap portion, the peripheral reinforcement ribs on the upper edge and the roof overlap portion are placed on the field board and the peripheral reinforcement ribs provided on the lower edge are provided. The lower part, which is arranged in the lower row, is supported by being laid on a noji board via the upper edge of the tile body. Therefore, the tile body is supported at three places in the vertical direction with respect to the base plate so that a continuous space is not formed between the tile body and the base plate. The roof body is thin and flat because a recess is formed in the area where the reinforcing ribs provided vertically and the horizontally long overlapping overlapping section for separating the ascending and descending running water pieces are formed. Since it is made thin, the weight per unit area is reduced. In this way, although the tile body is reduced in weight, the load and the like are dispersed through the peripheral reinforcement ribs provided in the upper and lower, left and right surroundings and the inner region thereof, and the roof overlapping portion provided in the inner region of the peripheral reinforcement ribs, The structure becomes robust without generating chips and cracks, and warpage and distortion can be prevented during transportation and curing during molding.

In the same manner as above, nails are driven into the plurality of mounting holes 10 and the opposing ends of the other adjacent tile bodies 1 mounted on the base plate 12 are laid. Also, if necessary, the concave portions 6A ₁ , 7A ₁ ; 6B ₁ , 7B ₁ of the roofing portions 6B, 7B; 6A, 7A facing each other are overlapped, and the tile bodies 1 adjacent to each other are roofed for waterproofing. Also, if necessary, an adhesive such as cement is filled into the recesses 6A ₁ and 7A ₁ ; 6B ₁ and 7B ₁ and solidified. In this way, the tile body 1 is sequentially laid in the same row over substantially the entire area in the left-right direction. At this time, for the remaining space located at the beginning and end of the roof in the same row, one tile body 1 is cut to a sufficient length from the end as shown by the imaginary line in FIG. The main body 1 'and the roof end tile main body 1 "are prepared according to the situation at the site, respectively, and the roofing sections 6A, 7A; 6B, 7B are similarly roofed, and the first and second rows are roofed thoroughly. .

Concave portions O, O 'surrounded by R ₉ and R ₁₀ are formed and disposed between the roof Y and the base plate 12. Therefore, this recess O,
O 'serves as an air layer to exhibit the heat insulating function, or it can be used as a storage part for packing a heat insulating material (not shown) into a predetermined position without moving, thereby ensuring sufficient heat insulating properties. it can. Also, as described above, the recesses O, O '
Is formed, the rain sound during rainfall is quiet because an air layer is formed and the sound is blocked.

Thereafter, the third and fourth rows from the tip of the eave are provided with running water pieces 2a, 2b, 2c; 3a, 3b, 3c of 2 rows and 3 columns by the same procedure.
One roof body 1 is used for roofing at a time in the left-right direction. At this time, the lower edges of the small pieces of flowing water 3a, 3b, 3c located in the third row are covered with a desired width with respect to the upper edge of the small pieces of flowing water 2a, 2b, 2c in the second row from the eaves. (See FIGS. 1 and 2).

In this manner, the entire roof Y is laid in a zigzag pattern using the tile body 1 from the inclined surfaces on both sides of the roof ridge portion toward the ridge portion, and mortar, cement, etc. Laying work can be performed by filling with an adhesive and closing it with a roof tile (not shown).

Considering the amount of drainage of rainwater in the small pieces of flowing water in each row and column when rain falls on the roof Y laid in this way, the following is obtained.

In FIG. 1, it is assumed that rainwater of 1V is rained on each of the flowing water pieces 2a, 2b, 2c,... Arranged in the first row closest to the ridge.

Next, considering the amount of drainage of the flowing water pieces 3a, 3b, 3c, for example, with respect to the flowing water piece 3b (hatched portion in FIG. 1), the flowing water piece 3b has a rainfall of 1 V and From the flowing water small pieces 2b and 2c which are partitioned and arranged in ascending order, 1 / 2V of the rainfall 1V is drained respectively. At this time, since the grooves 5 which are substantially coincident with the lower edge center line M of the ascending flowing water piece 2b and partition the running water small pieces 3a, 3b adjacent to the descending are arranged, the descending flowing water piece 3b is arranged. The rainfall of 1 / 2V + 1 / 2V is distributed from the flowing water pieces 2b and 2c located on the ascending line respectively. Therefore, the rainfall amount 1V and the drainage amount 1 / 2V + 1 / 2V become the total drainage amount 2V in the flowing water piece 3b.

Similarly, the total drainage of the flowing water small pieces 3a and 3b in the second row is the same as that of the flowing small water flowing 2
The sum of the drainage amounts distributed by 1 / 2V from b and 2c, that is, 2V is each drainage amount.

Then, considering the drainage amount of the flowing water pieces 2a, 2b, 2c,... For example, the flowing water pieces 2c (the hatched portion in FIG. 1), the rainfall of itself is 1V, whereas From the small flowing water pieces 3a and 3b located on the ascending line, 1/2 of the drainage amount 2V, that is, 1V × 2 is distributed and drained. Therefore, the sum of the rainfall amount 1V and the drainage amount 2V distributed from the two adjacent running water pieces 3a and 3b located in the ascending line is added.
V is the total drainage amount for the small flowing water portion 2b in the third row.

In the following fourth, fifth, sixth rows, etc., the flowing water pieces 3a, 3b, 3c ...; 2a, 2b, 2c ... each have a drainage volume of 4V,
5V, 6V…

Thus, the tile body 1 under this embodiment has the groove 5
Ascending running water pieces 2 that are separated from each other
a, 2b, 2c Descending flowing water pieces 3a, 3b, 3c on the lower edge center line M
Has a width l ₁ , for example, about 5 to 15 cm, and a thickness l ₂ on the surface so that the grooves 5 that define
Since it is integrally molded in a horizontally displaced state through a horizontally overlapping roofing section 4 of about 1.4 to 4.5 cm, the flowing water small pieces 2a, 2b, 2c; 3a, 3b, 3c located in The amount of drainage that increases exponentially with the rainfall of
From b, 2c; 3a, 3b, 3c, the water is surely distributed in approximately 1/2 amount and drained. Therefore, the ascending running water pieces 2a, 2b, 2c or the running water piece 3
a, 3b, and 3c are distributed efficiently and drained in an amount of about 1/2 on average without any local bias, so that the tile body 1 does not cause excessive force and is used for a long period of time. As a result, there is little deterioration and damage of the material, and the life resistance is improved. Moreover, as described above, 1
One of the flowing water nubs 2a positioned in a row on the tile main body 1, 2b, running water nubs 3a located 2c and descending, 3b, the width l ₁ and 3c, for example 5
The thickness l ₂ smaller width of about ~15cm is integrally molded via Fukiai Align overlapping portion 4 of the oblong about 1.4～4.5Cm, flowing water nubs 2a rain is located at the top row, 2b, and 2c The rainfall during rainfall is ensured without water leaking and infiltrating between the small flowing water pieces 3a, 3b, 3c located below. And temporarily
42.5cm, indeed roof Y area when using the tile main body 1 of about transverse 64.6Cm, 3.3 m the tile main body 1 of about 15 sheets can Fukiai Align used per ^2, also economical laying work efficiency Become The roof tile body 1 is provided with roofing portions 6A, 7A; 6B, 7B that are substantially symmetrically and laterally displaced on the front and back surfaces of both ends of the flowing water small pieces 2a, 2c; 3a, 3c located in the ascending and descending directions. Therefore, when the adjacent tile bodies 1 are laid on each other in the left-right direction,
Because the roofing parts 6A, 6B; 7A, 7B are displaced and do not coincide with one location, rainwater is drained without concentrating on the roofing location with respect to drainage during rainfall. There is no water leakage or leakage.

9 to 10 show another embodiment of the present invention. In this embodiment, small pieces 2a and 2 of flowing water are arranged in two rows and two columns.
b; 3a, 3b are arranged displaced in the left and right direction, the number of small pieces of running water has been reduced compared to the above embodiment, making it easier to reduce the weight and handling, other The configuration and operation are the same as in the above embodiment.

In the above embodiment, the roof tile body 1 is formed of flowing water pieces in an array of 2 rows and 3 columns, or 2 rows and 2 columns. However, the number of rows and columns can be freely increased and the tiles are always located on the upper row and the lower row. The small pieces of flowing water 2a, 2b, 2c; 3a, 3b, 3c are not limited to being arranged in a zigzag pattern with different left and right phases, but the present invention does not depart from the present invention even if they are arranged in the same lattice pattern. .

Further, in the above embodiment, adjacent running water pieces 2a, 2b,
2c; 3a, 3b, and 3c are divided by a plurality of vertically arranged grooves 5 to divide them. However, in order to distribute rainwater downward and discharge it, the running water dividing means is not necessarily provided as shown in the figure. For example, a ridge may be used instead of the simple groove 5. The width of this ridge varies from narrow to wide. The distribution of running water is not limited to 1/2. The installation position or the number of the grooves 5 or the ridges can be easily increased or decreased. Further, the width of the groove 5 is not limited to the illustrated case, but may be narrow or wide.

〔The invention's effect〕

As described above, according to the present invention, a suitable number of recesses are formed on the back surface of the tile body to reduce the weight per unit area. When laying and constructing a small piece of running water equivalent to several tiles on the roof at one time, the worker can easily transport the tile body on a roof or other high places. It is easy to handle, and the roofing work can be done efficiently and safely without time and labor.

On the back side of the tile body, a vertically extending branching rib is provided inside the surrounding reinforcing ribs surrounding the periphery, and a horizontally long overlapping part that separates the ascending flowing water piece and the descending flowing water piece. The tile body itself is reinforced by the provision. Moreover, at the time of roofing of the tile body, the peripheral reinforcing ribs provided on the upper edge and the roofing overlapping portion provided horizontally in the inner area of the peripheral reinforcing ribs placed on the periphery are placed on the top surface of the roofing board And the surrounding reinforcing ribs provided on the lower edge are placed on the field board via the upper edge of the lower tile body which is laid down in the lower row, and are supported by the field board at three places in the vertical direction. Therefore, a space portion corresponding to the thickness of the tile body is formed almost entirely continuously between the tile body and the base plate as in the related art, and the tile body is laid in a state of being raised from the base plate. There is no. For this reason, the structure of the tile body is ruggedly stiffened instead of being lightened so as to have a large laying area. Therefore, when the worker steps on the tile body and applies weight while working, the cracks and chips of the tile body can be prevented and the tile body can be transported after compression during molding, or the tile body can be distorted or warped during curing. Can be prevented,
