DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a positioning jig used for installing a floor panel used as a floor material of a house at a predetermined position on a beam.

[0002]

2. Description of the Related Art Usually, when constructing floors such as houses,
First, after assembling the frame, a floor panel made of lightweight cellular concrete (hereinafter, referred to as “ALC”) or the like is arranged on a floor beam assembled so as to be arranged at a predetermined position, and mortar is put on joints. Pour and join to form a floor slab. Thereafter, a floor is formed by attaching a floor base and a floor finishing material on the floor slab.

Here, when the floor panel is arranged on the floor beam, it is usually performed by the following method. That is, as shown in FIG. 9, first, several floor panels 12 are lifted and moved by a crane in a state of being stacked, and placed on the floor beams 7. On this occasion,
The lowermost floor panel 12a of the superimposition is accurately placed at the position where it is to be finally placed. Next, the superimposed floor panels 12 are sequentially moved from the top and arranged around the lowermost floor panel 12a. And by repeating this work,
The floor panel 12 is arranged on the entire floor surface. The floor panel 12 is lifted and arranged by a crane,
The reason is to prevent danger when the operator carries it because of its heavy weight, and to prevent damage due to strong impact or the like.

[0004]

When the floor panel 12 is placed on the floor beam 7 by the above-described method, if the position where the lowermost floor panel 12a is placed is displaced, the surroundings of the floor panel 12a are displaced. The other floor panels 12 placed at the same time cannot be placed at the correct positions. On the other hand, it is difficult to move the superimposed floor panel 12 to an accurate position after the floor panel 12 is removed from the crane in view of the weight of the floor panel 12, and there is a possibility that the floor panel 12 may be damaged when moving. .
Therefore, when the superimposed floor panel 12 is lifted by a crane and placed on the floor beam 7, it is necessary to arrange it at an accurate position.

Therefore, conventionally, a dimension 13 is previously measured from a reference position, and a mark 13 is attached to the floor beam 7 at an accurate position where the lowermost floor panel 12 is to be arranged. The floor panel 12 was lifted and lifted by a crane, and the crane was lowered while being adjusted by an operator to match the mark 13. However, in such a conventional method, first, the work for measuring the dimensions is complicated and time-consuming, and the work of accurately arranging the floor panel 12 in accordance with the mark 13 is difficult. There was a problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is provided when the floor panel is arranged on the floor beam.
In particular, the present invention provides a panel positioning jig for lifting and moving the superimposed floor panel by using a crane and allowing the panel to be easily and accurately positioned when being arranged on the floor beam. It is a technical task to do so.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A panel positioning jig according to an embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a panel positioning jig 1 according to an embodiment of the present invention includes a main body 4 having a bottom surface 2 and a vertical contact surface 3 formed at right angles to the bottom surface 2 and a beam. A plurality of positioning pins 5 protruding from the bottom surface 2 for insertion into the mounting holes, and a width of the vertical contact surface 3 so as to be perpendicular to the bottom surface 2 and the vertical contact surface 3. And a contact protruding plate 6 protruding from the center in the direction. Hereinafter, this will be described in more detail.

As shown in FIG. 1, the main body 4 of the panel positioning jig 1 is formed in an L shape in which two rectangular flat plates are joined at one side to each other so as to be perpendicular to each other. Thus, the main body 4 has the bottom surface 2 and the vertical contact surface 3 perpendicular to the bottom surface 2. The two rectangular flat plates may be joined by welding, bolting, or the like. However, in some cases, the L-shaped main body 4 may be formed by cutting out one member. The shape of the main body 4 is not limited to this, and may be any shape as long as it has a bottom surface 2 and a vertical contact surface 3 that are perpendicular to each other. Therefore, for example, as shown in FIG.

On the bottom surface 2 of the main body 4, a plurality of positioning pins 5 are provided to protrude. The positioning pin 5 is provided to fit into a mounting hole formed in the beam, and is provided corresponding to the shape and position of the mounting hole formed in the beam. Normally, as shown in FIG. 3, a large number of mounting holes 9 are formed at predetermined positions of a flange portion 8 in a beam 7 made of a steel frame so as to be combined with a column or another beam or to attach a bracing. . The positioning pin 5 is formed so as to be able to be inserted into such a mounting hole 9. That is, the positioning pins 5 are mounted on the bottom surface 2 of the main body 4 at the same intervals as the intervals at which the mounting holes 9 are provided, and the diameter thereof is slightly smaller than the diameter of the mounting holes 9. It is formed in a cylindrical shape having a smooth surface. The length of the positioning pin 5 is not particularly limited, and it is sufficient that the length is slightly longer than the thickness of the flange portion 8 of the beam 7 in which the mounting hole 9 is formed.

The bottom surface 2 of the main body 4 of the positioning pin 5
A method such as welding or bolting is used for attachment to the base. At this time, in order to ensure that the bottom surface 2 of the main body 4 is in close contact with the flange portion 8 of the beam 7, a fillet is used when mounting is performed by welding, and a bolt is used when mounting is performed by bolting. It is necessary that both ends do not protrude from the bottom surface 2 of the main body 4.
For this reason, a through hole is formed upward from the bottom surface 2 of the main body 4, and the positioning pin 5 inserted into the through hole is fixed and attached by welding from above or by bolting from above or from the side. It is good to do. The number of the positioning pins 5 is four in FIGS. 1 and 2, but may be two or three.

The vertical contact surface 3 of the main body 4 is perpendicular to both the bottom surface 2 and the vertical contact surface 3.
A contact protruding plate 6 is provided so as to protrude from the widthwise central portion of the vertical contact surface 3. The contact plate 6 is a rectangular flat plate, one side of which is joined to the vertical contact surface 3. Therefore, the side surfaces 10 on both sides of the contact protruding plate 6
And the vertical contact surface 3 form two corners which intersect at right angles, and these two corners become the contact corners 11 for positioning the panel. That is, as shown in FIG. 4, the panel 12 can be accurately and easily positioned by contacting the contact corner 11 with the corner of the panel 12 so as to be fitted. For this reason, when the panel positioning jig 1 is mounted by inserting the positioning pin 5 into the mounting hole 9 of the beam 7, the positional relationship between the contact angle portion 11 and the positioning pin 5 is determined. The abutment corner 11 is formed so as to coincide with the corner of the panel 12 when the panel 12 to be positioned is to be finally arranged.

The thickness t of the contact protruding plate 6 is equal to the thickness of the panel 1.
2, the thickness is equal to the specified dimension of the gap d between the joints of the adjacent panels 12. As a result, FIG.
As shown in (2), when the corners of the panel 12 are positioned in contact with each other, the gap d of the joint of the panel 12 can be set to a specified size. In addition, mortar is poured into the gaps between the joints of the panels 12 from above, thereby joining the panels 12 to each other.

The height h of the contact protruding plate 6 is not limited to the same height as the height of the vertical contact surface 3 as shown in FIG. The height may be about half the height of the contact surface 3 or may be another height. That is, the contact protruding plate 6
Forms the contact corner 11 for positioning the panel 12 as described above, so that one of the contact surfaces for contacting the corner of the panel 12 for positioning is used. It is sufficient that a sufficient size can be ensured, and for that purpose, it is sufficient that the panel has a height of about half or more of the thickness of the panel. However, even in that case, it is necessary that the lower end of the contact protruding plate 6 be formed near the bottom surface 2 of the main body 4. Similarly, the amount of protrusion of the contact protruding plate 6 from the vertical contact surface 3 is not particularly limited, and the other contact for abutting the corner of the panel 12 for positioning. It suffices if a sufficient size can be secured as the contact surface.

A method such as welding or bolting is used to join the contact protruding plate 6 to the vertical contact surface 3. At this time, the corner of the panel 12 is
In order to make sure that the contact angle can be brought into close contact with the contact surface, the contact angle portion 11 is joined so as to be exactly perpendicular to both the bottom surface 2 and the vertical contact surface 3. When joining is performed by welding, it is necessary to prevent both the fillet and the tip of the bolt from projecting into the contact angle portion 11 of the main body 4 when the joining is performed by bolting. For this reason, the mounting is performed by a welding method with a small fillet, or a female screw is provided on the joint surface of the contact protruding plate 6, and a through hole is provided at a position corresponding to the vertical contact surface 3, and It is good to join them by bolting them.

Next, a method of using the panel positioning jig 1 according to the embodiment of the present invention will be described. Usually, when constructing floors such as houses, first assemble the frame,
A floor panel 12 made of ALC or the like is arranged on a floor beam 7 assembled so as to be arranged at a predetermined position, and mortar is poured into joints and joined to form a floor slab. Thereafter, a floor is formed by attaching a floor base and a floor finishing material on the floor slab, respectively.

When arranging the floor panels 12 on the floor beams 7, as shown in FIG. 6, the floor panels 12 are first lifted and moved by a crane in a state where several floor panels 12 are stacked. And place it on the floor beam 7. next,
As shown in FIG. 7, the superimposed floor panels 12 are sequentially moved from the top and arranged around the bottom floor panel 12a. By repeating this operation, the floor panel 12 is arranged on the entire floor surface.

When the floor panel 12 is arranged on the floor beam 7 by such a method, the position of the lowermost floor panel 12a of the superimposed floor panels 12 is determined as follows.
If the floor panel 12a is displaced from the position where the floor panel 12a is finally to be arranged, it becomes impossible to arrange another floor panel 12 closely arranged around the floor panel 12a at an accurate position.
On the other hand, it is difficult to move the position after removing the superimposed floor panel 12 from the crane in view of the weight of the floor panel 12, and the floor panel 12 may be damaged during the movement. There is also. Therefore, when the superimposed floor panel 12 is lifted by a crane and placed on the floor beam 7, the lowermost floor panel 12a needs to be accurately placed at a position where it should be finally placed. is there.

Therefore, the panel positioning jig 1 according to the present embodiment is attached to the floor beam 7 in advance as shown in FIG. 6, and the floor panel 12 lifted by a crane there is attached to the panel positioning jig. By arranging the floor panel 12a with the tool 1 as a reference, the lowermost floor panel 12a is accurately arranged at a position where it is to be finally arranged. The number of the panel positioning jigs 1 is at least one, preferably, as shown in FIG.
As shown in (2), two of the floor panels 12 are attached at positions corresponding to the corners at both ends of the long side.

The floor beam 7 has a large number of mounting holes 9 at predetermined positions of a flange portion 8 for coupling with columns and other beams, and the panel positioning jig 1 is connected to the floor beam 7. As shown in FIG. 8, the mounting is performed by inserting a positioning pin 5 provided on the bottom surface 2 of the main body 4 into a mounting hole 9 of the floor beam 7. Then, the panel positioning jig 1
As described above, when the positioning pin 5 is inserted into the mounting hole 9 of the beam 7, the contact angle portion 11 finally moves the lowermost floor panel 12a to be positioned. Since it is formed so as to coincide with the position of the corner of the panel 12a when it is arranged at the position where it should be arranged, FIG.
As shown in FIG. 3, the lowermost floor panel 12a is brought into contact with the contact corner 11 by fitting the corner of the lower floor panel 12a into the lowermost floor panel 12a. The positioning of the panel 12a can be performed accurately and easily. Thereafter, another floor panel 12 is arranged around the lowermost floor panel 12a accurately arranged at the position where the floor panel 12 is to be finally arranged, so that the floor panel 12 is placed on the entire floor surface. Can be arranged. When the floor area on which the floor panels 12 are arranged is large, it is necessary to lift and move the superimposed floor panels 12 by using a crane, and to perform the disposing operation several times. Also in this case, the panel positioning jig 1 is disposed at a predetermined position of the floor beam 7 each time, and the same operation as the above-described operation is repeatedly performed, whereby the floor panel 12 can be disposed on the entire floor surface. it can.
