Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

According to one aspect of the present invention, there is proposed a mortar which is fixed in the course of building materials. 1, the building material is exemplified by bricks 11, blocks 12, and tiles 13, but is not limited thereto. The equipment for generating mortar is excluded and only the water is added at the same time as the mooring so that the fixation proceeds.

The mortar member 20 according to the present invention is formed into a standard set by mixing cement, sand, a fine powder mixture, carbon fiber, acrylic resin powder, and additives. Cement, sand, and fine powder mixture are mixed in the range of 65 ~ 85wt% as the main component. Cement is made by mixing Portland cement containing a lot of lime components as a main component and fast cement selected from alumina cement or calcium sulfoaluminate (CSA). The sand is preferably mixed with two or more species having different particle sizes in the same ratio. The fine powder mixture is mixed with blast furnace slag powder, titanium powder and kaolin powder selectively. The carbon fiber is a pitch system having a length of 12 mm or more and, in some cases, it is advantageous to increase the strength by mixing with PVA fibers. Acrylic resin is an admixture which is pulverized to a size that quickly reacts with water in the field. The additives may be selected from a fluidizing agent, an organic thickener, a coagulation retardant, and a crack inhibitor depending on the application.

The mortar member 20 thus formed is produced in various sizes as shown in FIGS. 3 and 4 to be described later, so that it can be selected in the construction process.

According to the present invention, the sealing sheet (25) for preventing moisture from penetrating into the inside easily dismounts the outer surface of the mortar member (20). And is individually packed in the sealing sheet 25 so as to prevent sticking due to moisture while the mortar member 20 is stored and transported. The sealing sheet 25 is made of a resin having strength, abrasion resistance, heat resistance and weather resistance, and is integrally formed except the inlet of the structure which is easy to disassemble. As described above, the sealing sheet 25 is opened in the field so that the mortar member 20 is immediately used, and even if the mortar member 20 is left after the completion of the construction, the waste material can be minimized.

The mortar member 20 includes a core material 21 on at least one side of the core material 21 and a shell material 22 which is formed by further adding staple fibers to the core material 21 . 2 illustrates a state in which the cover material 22 is formed on the upper surface of the core 21. FIG. The staple fiber is a short-length fiber material having a length of 5 mm or less, which improves the water permeability while maintaining the physical properties of the core material 21. As the short fibers, polyethylene fibers, polypropylene fibers, polyacrylonitrile fibers, and polyamide fibers are selectively used. The shell material 22 may slightly increase the content of the admixture than the core material 21.

As a detailed configuration of the present invention, the mortar member 20 is standardized to be at least one of a rectangular shape 31, a concave and convex shape 32, an A-shaped 33, an L-shaped 34 and a square 36 . FIG. 3 (a) illustrates use for block 12, FIG. 3 (b) illustrates use for brick 11, and FIG. 4 illustrates use for tile 13.

3 (a), a block 12 in which the through hole 15 is circular and a block 12 in which the through hole 15 is square are arranged adjacent to each other. In the construction of the block 12, the mortar member 20 of the rectangular shape 31, the concavo-convex shape 32 and the A-shape 33 is divided by dividing the region (upper surface and side surface) The rectangular shape 31 can be standardized to have a short length arranged horizontally and a long length arranged vertically. The concavo-convex mold 32 can be standardized in a form having at least one surface bent in the rectangular box 31. [ The A-shape 33 can be standardized in a shape corresponding to half of the mortar area.

In Fig. 3 (b), the brick 11 can be used as the mortar member 20 of the rectangular shape 31 described above. However, it is preferable to use the mortar member 20 of the L-shape 34 because the brick 11 and the block 12 intersect at right angles at the corner of the building. Of course, the L-shaped portion 34 is not limited to such use, and can be standardized in various forms.

In FIG. 4, the tiles 13 having a relatively small size and a small weight can be arranged in a predetermined area and the mortar member 20 can be applied at the same time. In this case, it is preferable to use an auxiliary member 40 which temporarily provides an adhesive force on the entire surface of the tile 13. [ It is possible to add the mortar member 20 of the square 36 to the rear surface of the plurality of tiles 13 attached to the auxiliary member 40. [ The square 36 is formed in a larger size and thinner than the rectangular shape 31. Of course, if the number of the tiles 13 attached to the auxiliary member 40 is increased, a rectangular shape 31 having a narrow and long band shape may be used instead of the square shape 36. [

1, the auxiliary member 40 may be used in the process of constructing the bricks 11 and the blocks 12. In this case, the auxiliary member 40 is used in the form of a plate or a jig rather than a sheet.

As a modification of the present invention, the mortar member (20) is further provided with a groove (23) for temporarily storing water on at least one surface thereof. 1 and 2 illustrate a state in which recesses 23 are formed on the upper surface of the mortar member 20. As shown in FIG. The water is temporarily stored in the groove 23 in order to delay the flow of water added to the mortar member 20 in the process of assembling the building material. Water filled in the groove (23) is sufficiently and rapidly transferred to the core (21) through the shell material (22) to cause stable fixing.

As a detailed construction of the present invention, the sealing sheet (25) is further provided with a release agent on its inner surface so as to be easily separated from the mortar member (20). The releasing agent is a resin component having an environmentally friendly property, and the liquid phase is excluded and added in powder form. The releasing agent may be applied directly to the inner surface of the sealing sheet 25 or the releasing paper may be closely attached to the inside of the sealing sheet 25. [ In any case, the sealing sheet 25 can be easily separated without damaging the mortar member 20 during the construction process.

According to another aspect of the present invention, there is proposed a method of constructing using the instantly fixed mortar of claim 1. The mortar member 20 described above is used for building materials such as bricks 11, blocks 12, and tiles 13 to facilitate quick and convenient and eco-friendly construction.

According to the present invention, the standard combinations of the mortar members 20 are selected in accordance with the shapes of the bricks 11, the blocks 12 and the tiles 13, which are building materials. The right side of FIG. 3 (a) shows a case where six short rectangles 31, two long rectangles 31, and two concave-convex types 32 are selected for one block 12. The left side of FIG. 3 (a) is a case where two A-shaped portions 33 are selected for one block 12. FIG. Of course, this is merely an example and various combinations are possible. The side face where the block 12 and the block 12 are adjacent may use a rectangular shape 31 or an L shape 34. [

Further, according to the present invention, after the sealing sheet 25 of the mortar member 20 is removed, it is placed in a predetermined position or inserted, and water is added. The mortar member 20 from which the sealing sheet 25 has been removed is placed on the upper surface or inserted into the side surface as shown in Fig. 3, and water is added by a water gun, spray or the like.

As a detailed configuration of the present invention, at least one of the bricks 11, the blocks 12 and the tiles 13 is provided with a mortar member 20 in a state of being gathered through a plurality of auxiliary members 40 . 1 illustrates an auxiliary member 40 for the brick 11 and block 12 and an auxiliary member 40 for the tile 13 in FIG. In any case, it is possible to collect a large number of units at different locations and move them using the equipment so that they can be quickly assembled and assembled in the field.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
