Description

  The present invention relates to a construction method for constructing a floor surface such as an interior of a building, a rooftop of a building, an exterior floor, and a product (support frame) used therefor.

  Conventionally, stones and tiles in buildings and exterior construction work are laid with empty mortar on the foundation, and then a professional profession sticks stones and tiles along the water thread while watching the joint spacing one by one. It is a general construction method that works by deciding the interval by going or by bonding.

In addition, a surface layer material such as stone or tile is bonded in advance to the surface of the elastic body having a high water absorption rate, and the elastic bodies are lined up after impregnating the elastic bodies with mortar, and the entire surface layer body is pressed from the surface to the same level. There is a construction method in which a profession is cured in a state and a floor is constructed, thereby eliminating the trouble of a professional profession sticking the surface layer material one by one while looking at the joint spacing (see, for example, Patent Document 1).

[Example of joint anchor construction]
The support frame 1 shown in FIGS. 1A, 1B, and 1C is made of a lightweight material such as foamed resin, and has a predetermined joint width on one main surface (upper side) of a rectangular flat plate shape. Then, a plurality of recesses 3 are provided, each of which is divided by a joint frame 2 that crosses vertically and horizontally and into which finishing materials such as stones and tiles enter, and the joint frame 2 penetrates vertically at predetermined intervals. A through-hole 4 that extends at the bottom is provided, a horizontally long recess 5 for installing a curbstone or the like is provided at one end of the support frame 1, and a baseboard mounting groove 6 is provided at both ends. .

  The size of the support frame 1 is not particularly limited, but is set to a size and a weight that can be easily carried by one person, for example, 60 cm × 60 cm to 1.5 m as a size. The thickness may be about 1.5 m and the thickness may be 50 to 300 mm, and the weight may not exceed 20 kg. In addition, white ant material is used for the material of the detached house.

  And when constructing a floor having a large area, a plurality of support frames 1 are arranged side by side. In this case, if the support frame 1 is not used for an end of the floor, a curbstone or the like is used. Since the horizontal recess 5 and the baseboard mounting groove 6 are not necessary, it is only necessary to prepare and prepare the support frame 1 in which these are omitted in advance, and because it is made of foamed resin, The horizontal recess 5 and the baseboard mounting groove 6 may be cut and removed on site, and the support frame 1 installed at the end is scraped off at an arbitrary portion (for example, in the middle of the recess 3) according to the floor area. May be. If a thin heating wire is used for the cutting, the cutting operation can be completed quickly and easily, and there is no need for a conventional chipping operation like concrete. In this case, the finishing material is also cut according to the size of the cut recess 3.

  In addition, the support frame 1 can be connected at the same height, and a level or level can be easily established by inserting a resin or metal plate and connecting it. Yes, there is no problem of being blown away by the wind even when used outdoors.

  2A, 2B, and 2C show a method of forming a floor surface using the support frame 1. First, the support frame 1 is smoothed before the support frame 1 is installed. The ground surface is finished so that it can be attached to the surface. However, for example, if a flow agent is poured on the concrete floor 7, the level material 8 that automatically hardens and forms a smooth ground surface is flown to create a horizontal surface. After the curing, the support frame body 1 shown in FIG. 1 is installed thereon (FIG. 2A). In addition, in order to level out, you may level out using not the level material 8 but empty kneaded mortar and a concrete foundation.

  The base made of the level material 8 and the support frame 1 are fixed with an adhesive or the like. However, since the support frame 1 is lightweight in these constructions, it is not necessary to carry heavy cement or sand as in the prior art. In addition, when it is necessary to dismantle under the floor at the time of inspection, the base and the support frame 1 may not be bonded. Further, when the thicknesses of the finishing materials are different, adjustment is performed by applying a caulking material or the like between the support frame 1 and the finishing material.

  In addition, although not shown in figure, when the magnitude | size of a construction place differs from the support frame 1 as mentioned above, the support frame 1 is cut | disconnected or another support frame is added, and it matches with a process dimension. Lay down.

  Next, after applying adhesive 9 (or caulking) to the bottom surface of the recess 3 of the support frame 1, a stone plate 10 as a finishing material is installed in each recess 3, The baseboard 11 is inserted (FIG. 2B). In some cases, the stone flat plate 10 is merely fitted into the recess 3 without using an adhesive.

  Of course, the part in which the support frame 1 is cut in the middle of the recess 3 uses a stone flat plate 10 cut according to the cut.

  Since the shape of the concave portion 3 of the support frame 1 and the stone plate 10 of the finishing material are the same size, a beautiful finish can be automatically ensured simply by fitting, and work can be done without being a specialist as in the past. As a result, the cost can be greatly reduced, and environmental pollution problems such as noise, dust, and remaining materials at the site can be solved.

  Thereafter, joint material 12 made of elastic mortar or caulking is basically placed in the gap between the stone plates 10 (part of joint frame 2). The joint material 12 also enters the through-hole 4 and reaches the lower enlarged portion (FIG. 2C).

  As in this construction example, the joint depth becomes shallow due to the presence of the joint frame 2, and there is a possibility that the joint will peel off. However, the joint material 12 enters the through-hole 4 and solidifies and integrates. It will serve as an anchor that prevents the entire joint from coming off.

  FIG. 3 is a plan view of the completed floor surface, wherein 13 is a meteorite and 14 is a wall board. Although not shown, when the floor area is large, a plurality of support frame bodies 1 are connected vertically and horizontally to form a floor surface. In this case, the horizontally long recess 5 and the baseboard mounting groove 6 of the support frame body 1 are cut. As a result, the support frames 1 are connected to each other, and the meteorite 13 and the wall board 14 are arranged at necessary portions.

  In the case of this embodiment, the joint frame 2 is continuously formed in all joint formation portions to form complete recesses, but the joint frame 2 is not necessarily provided in all joint formation portions, and the stone plate 10 May be provided as long as it can be fitted and fixed. For example, it may be provided partially only at the four corners of the rectangular portion corresponding to the recess 3 in the drawing, or may be provided partially on the four sides. .

  In the above case, the through hole 4 provided in the joint frame 2 is not necessarily provided only in the upper surface of the joint frame 2, but the joint material 12 may be provided in a planned portion serving as a joint of the support frame 1. In this embodiment, it is a hole that penetrates to the lower surface. However, if the shape and size of the joint material 12 enter, it may be a bottomed hole that does not penetrate to the bottom. good.

[Example of construction of permeable floor]
4 (A), 4 (B), and 4 (C) show a method for forming a permeable floor surface using the support frame body 1 shown in FIG. 1, and first, as in the case of FIG. 2, the support frame Before the body 1 is installed, the level material 8 (or empty kneaded mortar) is poured on the concrete floor 7 to create a horizontal plane. After the level material 8 is cured, the support frame 1 is installed thereon (FIG. 4 (A )).

  Next, after applying the adhesive 9 to the bottom surface of the recess 3 of the support frame 1, a stone plate 10 as a finishing material is installed in each recess 3, and the baseboard 11 is placed in the baseboard mounting groove 6. Is inserted, and the upper opening of the through hole 4 on the upper surface of the joint frame 2 is closed using a plug 15 made of plastic tech square material or the like as a lid (FIG. 4 (B)).

  Thereafter, the joint material 12 is put in the gap between the stone plates 10. The joint material 12 fills the gaps between the stone plates 10, but does not enter the through hole 4 due to the presence of the plug 15.

  If the plug 15 is removed after the joint material 12 is solidified, the upper surface of the through hole 4 is opened, and a permeable floor through which rainwater or the like passes is formed. In this case, since the support frame 1 is a soft material that does not absorb water with the foamed resin, it is waterproof and does not damage the support frame 1.

  In addition, if the lower expansion part of the through-hole 4 is previously connected by the adjacent through-holes 4 and made into a groove shape, this part becomes the water flow path 16 for discharging water.

  The water flowing into the water passage 16 is used as a water storage portion for storing water, and a fiber having high water retention or a similar material (not shown) is pasted on the back side of the stone plate 10, and this portion and the water passage 16 are connected. In the meantime, if a similar material having high water retention or water absorption is attached or interposed by means such as embedding in the support frame 1, the water is transferred from the water passage 16 as the water storage portion to the stone plate 10. Thus, the stone flat plate 10 can always be kept in a water retaining state and can be a floor that can prevent the heat island phenomenon due to a decrease in floor surface temperature due to heat of vaporization.

  FIG. 5 is a completed plan view of the permeable floor performed using the support frame body 1 of FIG. 1. The upper opening of the through hole 4 is exposed at the joint portion of the floor surface, and rainwater and the like are below the floor through this portion. Will be discharged.

  In this embodiment as well, the joint frame 2 is not necessarily provided in all joint formation portions, and may be provided in a partly scattered manner as long as the stone flat plate 10 can be fitted and fixed.

  In the case described above, the through hole 4 is provided on the upper surface of the joint frame 2 provided partially in consideration of the work of the lid with the stopper 15. If a hole (through hole) is separately provided in a portion where the frame 2 is not formed and the lid 15 is not covered with the plug 15, the joint material 12 enters the hole, so that the joints shown in FIGS. It will serve as an anchor.

  Of course, it is also possible to use the through holes 4 formed in the joint frame 2 as the anchors of joints by not using all the through holes 4 as the water permeable holes and without covering the partial through holes 4 with the plugs 15.

[Example of construction using a support frame made of other materials]
The support frame 17 shown in FIGS. 6A, 6B, and 6C is a case where the support frame 17 is made of a material having a relatively high bending strength, such as plastics, GRC, FRP, rubber, and light metal. If the same part as the frame 1 is described with the same reference numerals, one main surface (upper side) of a rectangular flat plate is partitioned by a joint frame 2 that swells vertically and horizontally, A plurality of concave portions 3 into which finishing materials such as tiles and the like enter are regularly arranged.
