  The present invention relates to a jig for constructing a large building material (particularly, a large tile exterior material). Specifically, the construction material can be moved to a construction position without damaging the building material, and can be safely used by a small number of people. The present invention relates to a construction jig for large building materials that can be easily constructed. Moreover, it is related with the construction method of the large sized building material using this construction tool for large sized materials.

  In recent years, exterior materials have been increased in size because of their high designability and shortening of the construction period, and various jigs and construction methods for constructing such large exterior materials have been developed. In particular, tile-type exterior materials (porcelain porcelain plates) have been further increased in size in recent years, and it has become necessary to develop jigs and construction methods for constructing such exterior materials.

  Conventionally, as disclosed in Patent Documents 1 and 2, jigs for constructing large exterior materials have been developed. These jigs are used to prevent peeling after construction of tile exterior materials (patents). Document 1) and the purpose of improving positioning work when attaching a tile exterior material to a wall surface and preventing peeling after construction (Patent Document 2).

However, since a large-sized exterior material is large in weight because of its large size, equipment and labor are required for the operation of moving to the construction position or the operation of actually attaching to the construction position. In addition, since the dimensions are large, breakage tends to occur during such work. In other words, the stage (process) that requires the most attention when constructing a large exterior material is the stage (process) that moves the large exterior material to the construction position or the stage (process) that is actually attached to the construction position. It is.
Therefore, in the jig and construction method for constructing a large exterior material, it is useful at the stage of moving the large exterior material to the construction position (process) and at the stage of actually attaching it to the construction position (process). It becomes important.

  In addition, the mounting member 2, the receiving member 3, and the connecting member 4 may be provided with a cushioning material (not shown) for preventing damage to the large building material when the large building material is placed or stood.

  In addition, the material of the mounting member 2, the receiving member 3, and the connecting member 4 is not particularly limited, and various materials such as metal, plastic, and wood can be used.

For the connecting member 4, an adjusting means 6 that adjusts the distance between the mounting member 2 and the receiving member 3 can be further provided.
The structure of the adjusting means 6 is not particularly limited as long as the distance between the mounting member 2 and the receiving member 3 can be adjusted. For example, for adjusting the receiving member 3 with a bolt. A structure in which several bolt holes (6a, 6b) are provided in the upper part of the connecting member 4 can be exemplified.
And when constructing a large building material having a large dimension in the height direction, as shown in FIG. 1 (a), a bolt through hole (not shown) is provided in advance in a bolt through hole (6a) provided at the uppermost portion of the connecting member 4. 1), after fitting the holes of the receiving member 3 with the bolts, the nuts are passed through the bolts, and when constructing a large building material having a small height dimension, as shown in FIG. The distance between the mounting member 2 and the receiving member 3 is adjusted by fitting a bolt through hole (not shown) of the receiving member 3 to a hole (6b) provided below the upper portion and then fastening the nut through the bolt. The method etc. can be mentioned.

  Next, the operation | movement (construction method of the large building material which concerns on this invention) and effect | action of the construction jig for large building materials comprised as mentioned above are demonstrated. FIG. 2 is a schematic diagram showing the first step of the construction method for large building materials according to the present invention, FIG. 3 is a schematic diagram showing the second step of the construction method for large building materials according to the present invention, and FIG. It is a schematic diagram which shows the 2nd jig | tool used for the construction method of the large-sized building material which concerns on invention, FIG. 5 is a schematic diagram which shows the 3rd process of the construction method of the large-sized building material which concerns on this invention, FIG. It is a schematic diagram which shows the 4th process of the construction method of the large sized building material which concerns, and FIG. 7 is a schematic diagram which shows the 5th process of the construction method of the large sized building material which concerns on this invention.

(First step)
First, the large building material 7 to be constructed is laid down, and the operator lifts both ends of the large building material 7 in such a state by using an auxiliary jig (not shown) or the like as necessary and moves it to the vicinity of the mounting member 2. Let
Next, the worker starts up the large building material 7 and the large building material 7 so that the front side of the large building material 7 faces the receiving member 3 as shown in FIG. 2 (so that the back surface 7a of the large building material 7 is opened). Is placed on the placement member 2. At this time, an adhesive may be applied to the back surface (construction surface) of the large building material 7 as necessary.

(Second step)
Next, the upper end portion of the large building material 7 is leaned against the receiving member 3, and the upper end portion of the large building material 7 and the receiving member 3 are clamped using the second jig 8 having a clamping function as shown in FIG. The building material 7 is fixed to the first jig 1 (the construction jig 1 for large building materials according to the present invention). In addition, in FIG. 3, although the upper end part of the large sized building material 7 and the receiving member 3 are clamped, it is not limited to this, The lower end part of a large sized building material and a mounting member are clamped as needed. Alternatively, both the lower end and the upper end of the large building material may be sandwiched between the placing member and the receiving member.

(Second jig)
Here, the structure of the second jig used in the second step is not particularly limited as long as it has a clamping function. For example, a U-shaped main body portion 9 and a fastening bolt portion as shown in FIG. 10 and the clamp 12 provided with the holding | suppressing part 11 can be mentioned.

(Third step)
Next, the first jig 1 on which the large building material 7 is placed is moved to the construction position. Here, since the large building material 7 is mounted on the first jig 1 and is fixed to the first jig 1 by the second jig 8, it can be moved to the construction position without being damaged. become.
The moving means is not particularly limited. However, as shown in FIG. 5, if a means for attaching a horizontal beam 14 to the scaffold 13 and installing a simple winch 15 on the horizontal beam 14 is adopted, the hook 16 of the simple winch 15 is attached. By simply hooking on the handle portion 5 of the first jig 1, the large construction material 7 can be installed by lifting the first jig 1 or moving along the cross rail 14 without using a large facility. It is suitable because it can be moved up to.

(4th process)
Next, after applying an adhesive to the construction position of the large building material 7 in the wall surface 17, the lower end of the mounting member 2 is inserted with the large building material 7 placed on the first jig 1 as shown in FIG. 6. In this way, the lower end portion of the large building material 7 is brought into contact with the construction position of the wall surface 17.

(5th process)
Next, by removing the second jig 8 sandwiching the upper end portion of the large building material 7 and the mounting member 2, as shown in FIG. 7, the large building material 7 is tilted from the member 3 to the wall surface 17. The upper end portion of the large building material 7 is brought into contact (adhesion) with the construction position of the wall surface 17 to complete the construction. At this time, the removed second jig 8 can be used to sandwich the upper end or lower end of the large building material 7 and the wall surface 17 until sufficient adhesive strength is exhibited.

Therefore, since the construction method for large building materials according to the present invention uses the construction jig for large building materials (first jig 1) according to the present invention, the large building materials (particularly large tile exterior materials) are damaged. Therefore, it can be safely and easily constructed by a small number of people.
In addition, since the construction work is performed with the lower end of the large building material always placed on the placing member, it is possible to prevent the large building material from falling during construction, and it is safe and easy. It will be possible to construct.

  The above is the basic operation of the construction method of the large building material according to the present invention, but the construction method of the large building material according to the present invention is not limited to this, for example, when constructing a large building material on a multilayer floor Can perform another step instead of the fourth step. FIG. 8 is a schematic diagram showing a jig temporary fixing step of a construction method for a large building material according to the present invention, and FIG. 9 is a schematic diagram showing a third jig used in the construction method for a large building material according to the present invention, FIG. 10 is a schematic diagram showing the induction process of the construction method for large building materials according to the present invention.

  First, the first to third steps are performed.

(Jig temporary fixing process)
Next, instead of the fourth step, a large building material 7 as shown in FIG. 8 is used by using a third jig 21 including a plate-like member 18, two insertion members 19 (19 a, 19 b), and a distance changing member 20. The third jig 21 is inserted into the gap 23 between the floors of the wall panel 22 existing at the lower end of the construction position, and the interval change member 20 is used to widen the interval between the insertion members 19 (19a, 19b). 3 Temporarily fix the jig 21.

(3rd jig)
Here, the structure of the third jig used in the third step is not particularly limited as long as it can be temporarily fixed in the gap between the floors of the wall panel, but the upper side plate portion 18a and the middle side as shown in FIG. A plate-like member 18 having a crank shape in side view composed of a plate portion 18b and a lower side plate portion 18c, two insertion members 19 (19a, 19b) projecting in the same direction connected to the upper side plate portion 18a, and an upper side plate It is preferable to use a member provided with a distance changing member 20 (an insertion bolt is used in FIG. 9) that changes the distance between two insertion members provided in the portion 18a, since the guidance process described later can be performed smoothly. .

(Guidance process)
Next, as shown in FIGS. 10 (a) and 10 (b), in the state where the large building material 7 is placed on the first jig 1, the lower end of the large building material 7 is temporarily fixed in the gap 23 between the floors. The large building material 7 is guided to the construction position of the wall surface 17 by being lowered onto the insertion member 19a of the tool 21 and sliding the lower end portion of the large building material 7 on the insertion member 19a.
Then, the construction of the large building material 7 is completed by performing the fifth step.

Therefore, even when constructing large building materials on multi-story floors, it is possible to construct safely and easily with a small number of people without damaging large building materials (particularly large tile exterior materials) by using the third jig. It will be possible.
In addition, since the construction work is performed with the lower end of the large building material always placed on the mounting member or the insertion member, it is more effectively prevented that the large building material falls during construction. Therefore, even when a large building material is constructed on a multi-story floor, it can be constructed safely and easily.

  The construction jig for large building materials of the present invention can be used for construction of large building materials (particularly, large tile exterior materials).
