Description

[Detailed description of the invention]

This invention relates to a tiling construction method, in which the tiles are temporarily attached to the concrete formwork in advance and the tiles are attached at the same time as the concrete is poured. We would like to be able to easily perform tiling on-site so that it can be adapted to the conditions of the construction site, and to achieve construction that is significantly superior in terms of accuracy, efficiency, and economy. Conventionally, tiles are temporarily attached to the concrete formwork in advance, and the tiles are attached at the same time as the concrete is poured.For the purpose of promoting efficiency, the tiles are placed at the factory using the specified unit materials described below. The use of so-called unit tiles, which are pre-installed in buildings, etc., was significant. In particular, typical materials for the units mentioned above include styrofoam boards, vinyl chloride sheets, rubber mats, and plywood veneers. However, in construction using unit tiles, the common thing is that the unit tiles are manufactured based on the design drawings at the design stage, or the unit tiles are manufactured to an extremely flush size, so the on-site dimensions and design drawings It was difficult to control on-site due to errors in the process and inability to adapt to the diversity of site dimensions, shapes, etc., and it was very time-consuming to install tiles by pouring, requiring extensive site management. . In addition, handling the tiles as unit tiles during transport is bulky and expensive. Among the above unit materials, in the case of styrofoam boards, it is necessary to securely hold the tiles and fix the position, so simply installing tiles on a board cannot withstand vibrations during concrete pouring. It has also been proposed to form a recess in the body for inserting the tile and to fit the tile into the recess in advance (see, for example, Japanese Patent Publication No. 48-19016), but since the dimensions of the tiles vary widely,
It has the drawback that it is difficult to enter, and there are gaps around the tile, resulting in insufficient tile retention. In addition, in the case of units that hold tiles using vinyl chloride sheets (for example, see Japanese Patent Publication No. 48-10854), there is a problem in disposing of the remaining material after use, and especially when manufacturing sheets by pouring, the thickness and other dimensions of the unit material are In addition to the lack of uniformity and the risk of poor tile finish, the finishing process at the factory was time consuming and the market price was high. Furthermore, with unit materials made of rubber mats, the tiles are held only at the joints, so tile retention is insufficient.
Repair work required after the concrete has fallen is troublesome, and the cost of the rubber itself is high, making it uneconomical. Moreover, because rubber mats are relatively thick and hard in order to maintain their shape, they are not suitable for use in small round-shaped parts of the site when holding tiles in areas corresponding to joints, as described above. there were. Furthermore, as a custom-made unit tile, in the case of a unit tile that is made of plywood as a unit material, the tiles are temporarily attached according to the blueprint and joints are filled between the tiles, which requires a lot of work to make into units. In particular, during on-site construction, many unit tiles must be arranged in an accurate order, requiring multiple on-site management, and it is not economical to transfer to other sites. Therefore, in this invention, in order to eliminate the drawbacks and inconveniences of the conventional tiling construction using various unit tiles mentioned above, we have developed a tiling construction method by placing tiles that can be applied immediately on site without using tiles as units. According to the construction method of the present invention, a temporary sheet made of an elastic sheet having a layered body capable of regulating expansion and contraction on at least one side and adhesive layers formed on both sides is temporarily attached to one concrete formwork. Next, place a joint frame made of hard material, which has squares formed by spaces corresponding to the tiles by increasing the joint spacing, on the temporary attachment sheet, and sequentially place the tiles in the squares of the joint frame. After inserting it and adhering it to the temporary sheet,
Remove the joint massing frame and leave only the tiles on the temporary sheet, then fill the joints between the tiles with a flexible and elastic joint massing sheet that matches this, adhere it to the temporary sheet, and then Concrete is poured between the rear tile and the other concrete formwork behind the tile, and after the tile is firmly fixed to the concrete, the concrete formwork on the tile surface side is removed and the temporary adhesive sheet is removed from the tile surface along with the joint mass sheet. It is characterized by being peeled off. Next, embodiments of the present invention will be illustrated below with reference to the drawings together with temporary attachment sheets and other items used for carrying out the embodiments. Figure 1 [1] to (9) sequentially show the process of tiling construction, Figures 2 and 3 show a part of the process, and 10 of each figure shows one of the concrete formworks. This shows a case where the stud 11 is arranged at appropriate intervals and the board 12 is made of plywood or the like. 20 is a temporary sheet, 30 is a joint mass frame made of hard material,
Reference numeral 40 indicates a flexible and elastic joint mass sheet, which is a necessary member for carrying out the tiling work of the present invention. 50 indicates tiles, and 60 indicates poured concrete. Before explaining the construction, the members necessary for the above-mentioned implementation will be sequentially explained.
It is shown in Figures to Figure 6, and is an elastic sheet,
A layered body 22 capable of regulating expansion and contraction is laminated on at least one side of a flexible sheet 21, and pressure-sensitive adhesive layers 23, 23/ are formed on both sides of the laminated sheet.
A release sheet 24 and 24' is attached to 23' so that it can be peeled off during use. In particular, for the flexible sheet 21, a foam sheet with a thickness of 2 to 3 mm and made of flexible and elastic resin such as foamed polyethylene sheet or foamed polypropylene sheet is suitable. A thin layer of metal such as aluminum is suitable, but
For the former, other foam sheets or the like can be used, and for the latter, sheets other than thin metal layers can be used, and both can be wound. Such a temporary sheet 20 has layered materials 22, 22 on both sides.
' (Fig. 5), and the layered body 23 on the tiled side may be printed with a checkerboard circular line 25 (Fig. 6), and the line 25 is used during the tiling construction described later. It has the advantage of being able to perform construction while checking to ensure that there are few deviations in parallel and perpendicular directions, and in the same way, forming go board-shaped lines on one of the release sheets is convenient for allocating tiles on site. Next, the joint mass frame 30 shown in FIGS. 7 and 8 is made entirely of metal, hard resin, or other hard material, and is a narrow body with a width corresponding to the joint spacing between tiles. 31 are arranged in a row to form a grid 32 with a space corresponding to the size of the tile. There are corresponding cases (Fig. 8), and in any case, the case where the entire body is made of aluminum is lightweight and easy to handle. The dimensions of the finished horizontal joints and vertical joints in tiling are, for example, when the size of the tile is 108 x 60 mm. When using the shape shown in Figure 8, the finished joints are, for example, horizontal joints 8wn,
In the combination of vertical joint 7rrrrn, the horizontal joint a of the joint square frame 30 is 7 m, the vertical joint b is 7 m, the horizontal dimension C of the square 32 is between two tiles and the joint 223, and the vertical dimension d is the horizontal joint. It is easy to use if you add 1 mm/Js less than the finished joint in a and make it 61 mm, which is one tile margin. Also, in the case of the other combinations of finished joint dimensions described above, the joint mass frame 30 is 1r from the finished joint on the horizontal joint a side.
rtm less, vertical dimension of grid 32 lf than tile size
Fl'm If you make it thick, it will be tile 500 which will be explained later.
This is preferable because the temporary fitting work can be carried out smoothly. Furthermore, the joint mass sheet 40 shown in FIG. 9 is formed from a flexible and elastic sheet, and for example, a foam sheet made of a synthetic resin such as a cross-linked foamed polyethylene sheet or a foamed polypropylene sheet is suitable. It is made up of a series of narrow bodies 41 having a width corresponding to the joint spacing between the tiles, forming grids 42 with spaces corresponding to the size of the tiles. In order to carry out tiling construction at a construction site using the above-mentioned members as shown in Fig. 1, the concrete formwork 10 (
Cl) step), first temporarily attach the temporary sheet 20 with the layered body 22 side facing the tile temporary attaching surface.
2.1 stage). Then, the joint mass frame 30 made of hard material is attached to the temporary attachment sheet 20.
([3] stage). Next, after sequentially inserting the tiles 50 into the squares 32 of the joint square frame 30 and adhering them to the temporary adhesive sheet 20 (step [4]),
The joint massing frame 30 is removed and only the tiles 50 remain on the temporary adhesive sheet 20 (step [5] and FIG. 2), and then the joint massing sheet 40 having flexibility and elasticity is filled into the joints 51 between the tiles 50. (Step [6]) The thickness of the tile 50 (for example, 6 to 7 mm) is the joint mass sheet 40.
(for example, 3 rrrm), so if it is difficult to fill, reuse the joint mass frame 30 that was removed earlier, or
Use other items to stuff the joint mass sheet 40, push the joint mass sheet 40 deep into the tile joints 51, and adhere the joint mass sheet 40 to the temporary adhesive sheet 20 ([7
] stages and Figure 3). Thereafter, concrete 60 is poured between the tile 50 and the other concrete formwork (not shown) behind the tile (step [8]). After a period of time necessary for the adhesion strength between the tile 50 and the concrete 60 to exceed the adhesion between the tile 50 and the temporary adhesive sheet 20, the concrete formwork 10 on the tile surface side is removed, and the temporary adhesive sheet is removed. Part 20 joint part 4
When peeled off from the tile surface together with 0, the tile 50 becomes attached to the concrete 60 (

[9] Stage). Incidentally, when driving the concrete IJ-contact 60, although not shown in the drawings, reinforcing bars are placed as appropriate if necessary. This invention is constructed with tiles as described above.
A hard material having grids 32 formed by spaces corresponding to tiles is formed on a temporary sheet 20 which is temporarily attached to one concrete formwork 10 using an adhesive layer without the need for nailing or the like. Apply the joint square frame 30 consisting of the square 32 of this
The tiles 50 are sequentially enlarged to match the temporary sheet 20.
Since the space corresponding to the size of the tile formed in the joint square frame 30 will not be distorted when it is adhered to the temporary adhesive sheet 20, the tile 50 will serve as a tile dividing ruler. It is possible to securely insert the joint mass frame 30 at predetermined positions one after another and achieve temporary adhesion using adhesive, which is also useful for controlling some errors between the design drawing and the site dimensions. Furthermore, since the joint massing sheet 40 inserted into the joint between the tiles 50, 50 is a flexible and elastic sheet, the joint massing sheet is made to expand and contract to accommodate dimensional errors in the tiles when inserted into the tiles 50. Not only is it very easy to perform joint filling, but it is also very easy to peel and remove the joint mass sheet 40 after concrete is poured, and the tiles can be removed without peeling or damaging them. It has the advantage that joints can be easily shaped. Moreover, the temporary adhesive sheet 20 to which the tiles 50 and the joint mass sheet 40 are adhered is made of an elastic sheet, and has a layered structure that allows the temporary attachment of the tiles to be good and that can restrict expansion and contraction on the side of the temporary attachment surface of the tiles. 22, the flexible seat 21
Dayu is suitable for preventing the entire temporary installation sheet 20 from sagging due to the weight burden during temporary installation of tiles,
In particular, if a thin layer of metal such as aluminum is used as the layered body 22, the adhesive layer 23 can be easily formed and the layered body 22 can be heat resistant to the curing heat of concrete, making it suitable. Furthermore, in the case of this invention, the tiles 50 are first adhered to the temporary adhesive sheet 20 using the joint mass frame 30 made of many hard materials. Since the joint mass sheet 40 having the following properties is packed into the tile joint, there is no risk of the joint mass sheet 40 being pressed down under the tiles 50, and is particularly suitable for tiling on a wide and flat construction site. Become something. Furthermore, in construction, tiles are not made into units, so it eliminates the disadvantages and inconveniences of using unit tiles.
In particular, the tiles can be transported to the site in boxes, making handling convenient. In addition, the above construction is very reliable in tiling that corresponds to the site conditions. R-Mo allows reliable tiling to be achieved without being affected by concrete pouring or rough removal of concrete formwork, and there is no floating or flowering phenomenon (hanatare) of the tiles, and it does not require skilled workers to perform the installation. This invention is a method that can be fully implemented in both cases, can shorten the construction period and reduce construction costs, and is an invention that can be expected to become popular in the future.
