Abstract

(57) [Abstract] [Purpose] In a tiled PC board that has a part to which tiles are to be pasted, measures are taken to improve the adhesive strength to the mortar for tile pasting on the concrete surface to which the tiles are to be pasted. . [Structure] In a portion where tiles are to be attached later, a dam plate 2 having irregularities 21 on the surface on which concrete 3 is placed is arranged to produce a tile-dried PC plate 1. When the barrier plate 2 is removed, irregularities are formed on the concrete surface on which the tiles of the tile driving PC plate 1 will be attached later. This improves the bite between the applied mortar and the concrete surface and prevents the tile from peeling.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tile-injected PC (precast concrete) plate having a portion to which tiles are later attached.

[0002]

[Prior art]

 For tile-cast PC boards (including tile-cast PC F <precast concrete foam> boards, etc.) that are attached to the frame as outer walls, scaffold ties can be connected to this to install scaffolds, and external work in the vicinity can be performed. is there. In such a tile driven PC board 1, as shown in FIG. 6, an anchor 6 is driven into concrete 3 and a long nut 6a for connection for connecting a scaffolding connection is connected to the outer end of the anchor 6.

Therefore, when manufacturing such a tile-driving PC board 1, as shown in FIG. The dam plate 12 having the added thickness is arranged by screwing the mounting bolts 4 into the connecting long nuts 6a, and the concrete 3 is placed. At the time of external work, a scaffolding joint is connected to the connection nut 6a, and at the end of the external work, the tile 5a is post-applied with mortar.

Conventionally, as such a dam plate, a steel plate or a wood plate whose surface on the concrete pouring side is smooth has been used, so that the concrete surface 31 to which the tiles are later attached has been formed smooth.

[0005]

[Problems to be solved by the device]

 As described above, in the conventional tile-implanted PC board having a portion to which the tile is later attached, since the concrete surface to which the tile is later attached is smooth, the adhesive strength between the applied mortar and the concrete surface is weak, and the tile Was often peeled off with the mortar.

Further, since such a post-pasting work of tiles is the final process of the external construction, the completion date of the construction period is approaching, so that it is not possible to take sufficient time for the work, and it is possible to improve the adhesive strength during the work. There was also a situation in which it was not possible to devise a device. The present invention has been made in view of the above-mentioned problems of the prior art. In a tile driving PC board having a part to which tiles are later attached, the mortar to be attached to the concrete surface to which the tiles are later attached. It is an object of the present invention to provide a tile-implanted PC board that has been devised to improve the adhesive strength with.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the tile-driving PC board of the present invention is a tile-driving PC board formed by disposing a weir board in place of a tile in a portion where a tile is to be attached later. The feature is that the surface on the driving side is provided with irregularities.

[0008]

[Action]

 According to the tile-driving PC board of the present invention, since the surface of the dam plate disposed in the portion where the tiles are to be post-applied is provided with irregularities, the tiles can be post-applied if the dam plate is removed. Unevenness is formed on the concrete surface. This improves the bite between the concrete surface and the applied mortar when the tile is later applied.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are cross-sectional views showing a tile driving PC board in this embodiment, FIG. 3 is a cross-sectional view showing the weir board in FIG. 1, and FIG. 4 is a plan view showing an example of the weir board. .

As shown in FIG. 1, in this tile-implanted PC board 1, a dam plate 2 having a thickness obtained by adding a margin to the thickness of a tile to be attached later is arranged in a portion where the tile is attached later. Although formed, a large number of irregularities 21 are provided on the surface of the barrier plate 2 on the side where the concrete 3 is cast. As the barrier plate 2, for example, as shown in FIG. 3, one side of a thick plate material 2a made of a steel plate or wood is provided with irregularities in a lattice shape or a stripe shape as shown in FIGS. 4 (a) and 4 (c). An elastic material such as a formed rubber sheet, or one having a concavo-convex member 21a made of a polyethylene sheet having a large number of cylindrical protrusions containing air as shown in FIG. 4 (b) is used. it can.

In addition, a hole 22 is formed in the central portion of the barrier plate 2 for passing the mounting bolt 4. As shown in FIG. 3, this hole 22 has an insertion hole 22a (a hole through which the shaft portion a of the mounting bolt 4 is inserted) having a small diameter on the side of the irregularities 21 and a storage hole 22b (a hole having a larger diameter and being concentric). The head 4b of the mounting bolt 4 is communicated with the hole).

Then, for example, as shown in FIG. 1, a tile 5 is arranged at a predetermined position of a bed (not shown), and a dam plate 2 is arranged at a portion to which the tile is to be attached, and a temporary joint material (not shown) is formed at a joint portion. And the concrete 3 is placed from above, and the tile-dried PC board 1 is produced by a conventionally known method. At this time, the shaft portion 4a of the mounting bolt 4 is inserted into the hole 2 of the barrier plate 2 from the side of the housing hole 22b so as to protrude before the insertion hole 22a, and the tip of the shaft portion 4a is connected to the scaffold joint. The head 4b of the mounting bolt 4 is housed in the housing hole 22b by being screwed into one side of the 6a, and the anchor 6 driven into the concrete 3 is screwed into the other side of the long nut 6a. .

Therefore, after the concrete 3 is hardened and cured, if the mounting bolt 4 is removed and the barrier plate 2 is removed, as shown in FIG. 2, the tile of the tile driving PC plate 1 is placed on the concrete surface 31 on which the tile is post-applied. Unevenness is formed. Then, when this tile driving PC board 1 is attached to the frame and is used for external construction, a scaffold tie can be connected to the long nut 6a for connection to install a scaffold, and after removing the scaffold tie, the tile 5a is attached later.

As a result, as compared with the conventional case as shown in FIG. 6 (where the tile post-pasting portion is formed smooth), the pasting mortar and the tile post-pasting are performed during the post-pasting work of the tile 5a. The bite with the concrete surface 31 to be removed is improved. As shown in FIG. 5, if the cross-sectional shape of the concave-convex member 21a of the barrier plate 2 is formed in a taper shape whose diameter becomes smaller as it goes away from the thick plate member 2a side, the concave-convex member 3 is removed from the cured concrete 3. It is suitable because it is easy.

[0015]

[Effect of device]

 As described above, according to the present invention, since unevenness is formed on the concrete surface to which the tile is to be applied later, the adhesiveness between the adhesive mortar and the concrete surface is improved during the operation of applying the tile to the posterior surface. Even if it is not possible to devise to improve the adhesive strength during the post-pasting work of tiles, the adhesive strength can be improved as compared with the conventional one.

As a result, it is possible to prevent the post-attached tiles from peeling off together with the mortar even if a sufficient time cannot be taken for the tile post-attachment work.
