Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floor stone pasting method for pasting stone materials such as granite and marble on a large area concrete floor.

Conventionally, the most common method of this type of construction is to spread so-called dry mortar on the concrete floor to a thickness of about 40 m/m to 50 m/m.
Place a stone on top of this dry-mixed mortar, and adjust the height of the stone by hitting the stone with a mallet to make it sink. After adjusting the height, lift the stone once and place it on top of the dry-mixed mortar. Remove the tro mortar from above, place the stones on top of the tro mortar again, and tap the stones with a mallet to adjust the height of the stones and align the joints of each stone. Once the adjustment has been completed over a predetermined area, joint mortar is poured.

By the way, in this conventional method of installing floor stones, it requires skill to adjust the height of the stones and align the joints by pounding the stones with a mallet, and the progress of the construction is affected by the weather, and there is If you simply remove tro mortar on top of air-mixed mortar, which is easily damaged, the adhesion of the stone is strong, and the stone tends to crack over time.Air-mixed mortar has a high water absorption rate, so in cold regions There were problems such as being susceptible to damage from freezing, generally having low work efficiency, resulting in high construction costs and long construction periods.

The present invention was made in view of the above circumstances, and
The purpose of the present invention is to provide a floor stone pasting method that is easy to construct, is susceptible to damage from rain and freezing, is capable of firmly fixing stones, and is capable of reducing construction labor costs and shortening the construction period. It is something.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 6.

The embodiment described here is an embodiment in which the present invention is applied to work in which stone is pasted on a large-area outdoor concrete floor. To paste stones onto a concrete floor, first, as shown in FIG. 1, a plurality of reference lines 2, 2, . . . are drawn at predetermined intervals on the concrete floor 1. Next, as shown in FIGS. 2 and 3, the reference line 2,
A plurality of base mortars 3, 3... are placed at predetermined intervals along the 2..., and the upper surfaces 3a, 3a of each
Construction shall be made so that the heights of ... are approximately the same. When constructing the foundation mortar 3, 3..., apply adhesive-containing tromortar 4, 4... on the concrete floor 1 in advance to ensure that the foundation mortar 3 is firmly fixed on the concrete floor 1. Make it.

Next, as shown in Figure 4, the foundation mortar 3, 3
...A plurality of stones 5, 5... are placed on top of these foundation mortar 3, 3... so as to straddle between adjacent pieces of foundation mortar 3, 3...
Place... The stone material 5 is made by forming a material such as granite or marble into a plate shape, and cutting this into a square. When installing this stone 5, a gasket 6 is interposed between the stone 5 and the foundation mortar 3 to finely adjust the height of the stone 5.
In this case, the packing 6 is preferably adhered to the base mortar 3 in advance using an epoxy adhesive or the like. In addition, in the installation work of the stones 5, a plate 7 having a predetermined thickness is inserted between adjacent stones 5 to align the joints between the stones 5.

In this way, if there is variation in the height of the upper surfaces 5a, 5a of each stone 5, 5..., apply mortar containing adhesive to the upper surface of the packing 6 around the stones 5, and apply the same mortar. Adjust the height depending on the thickness.

Then, after finely adjusting the joint alignment of each stone 5, 5..., the space 8 below each stone 5, 5...
(Stones 5, 5 between foundation mortar 3, 3...
... and the floor 1 and the foundation mortar 3, 3...
As shown in FIG. 5, a high fluidity expansion mortar 10 is injected into the space between the concrete floor 1 and the stones 5, 5..., and the mortar 10 is solidified to move the stones 5, 5... to the concrete floor 1 and the foundation mortar. Glue to 3, 3... Here, since a plate 7 for joint alignment is inserted between adjacent stones 5, 5..., the above-mentioned mortar 10 is inserted from the joint between each stone 5, 5... It will not stick out. and,
After the high fluid expansion mortar 10 has solidified, the plate 7 is removed and finishing mortar is filled in the joints 11 between the stones 5, 5, . . . to complete the work. FIG. 6 is a diagram showing the installed state of the stones 5, 5 after the construction is completed.

In the above embodiment, the packing 6 was interposed between the stone 5 and the base mortar 3 in order to finely adjust the height of the stone 5. However, without using this packing 6, the base mortar 3. A thin layer of adhesive-containing mortar may be applied to the top surface, and the thickness may be adjusted depending on the thickness of the mortar.

In addition, in the above embodiment, the base mortar was provided linearly along the reference line, and each base mortar was arranged in parallel at a predetermined interval, but the shape and arrangement of the base mortar were It is not limited to the example and may be modified as appropriate.

As is clear from the above explanation, according to the present invention, since the stones are installed on the foundation mortar, the height adjustment and joint alignment of the stones can be done extremely easily and accurately, making construction easier. Therefore, it is possible to reduce the construction labor cost and shorten the construction period. In addition, once a foundation mortar is constructed and stones are placed on top of it, even if high-flow expansion mortar is placed, the high-flow expansion mortar will be covered by the stones, making it susceptible to damage from rain and freezing. It has the advantage of being difficult. Furthermore, since high-flow expansion mortar is injected into the space below the stones, the stones can be firmly bonded to the concrete floor, which has the advantage of keeping the stones in beautiful condition for a long period of time.

Claims (1)

[Claims] 1. A plurality of foundation mortars are installed on a concrete floor so that the height of the upper surface of each foundation is approximately the same, and a plurality of stones are placed on these foundation mortars while aligning the joints of adjacent ones, and each foundation Place the stone with a height adjustment member interposed between it and the mortar, then inject high fluid expansion mortar between each stone between each base mortar and the concrete floor to bond each stone to the concrete floor. This floor stone pasting method is characterized by the following:
