DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to FIGS. FIG. 1 shows a wall 4 for partitioning a room between pillars 3 and 3 of a building such as an apartment house, and the wall 4 is constructed from the floor 1 on the first floor to the lower part of the floor 2 on the second floor. .

As shown in FIG. 2, the wall 4 is formed by combining a vertical member 8 and a horizontal member 9 in a lattice shape with a reinforcing bar or a wire rod at a factory according to the design.
The intersections 9a are welded to form various lattice planes 5, 6, 7
Is manufactured, and the pieces of the lattice planes 5, 6, and 7 are connected and constructed at a construction site. What forms a grid with a reinforcing bar is called a reinforcing bar grid, and those formed with a wire are called a welded wire mesh. The welding strength of the intersection 9a is defined so that the welded wire mesh is larger than the reinforcing wire grid. . The shape, size, and the like of each piece of the lattice planes 5, 6, and 7 are manufactured according to the layout drawing according to the design of the wall 4 as described above.

FIG. 2 (a) shows one piece of a regular lattice plane member 5 which is often used as a wall, and is manufactured in such a size that ten vertical members 8 are arranged at equal intervals. The horizontal members 9 which intersect with the vertical members 8 to form a lattice are disposed at equal intervals in the vertical direction between the vertical members 8 at both ends and are welded to the vertical members 8 at the intersections 9a. . A joint portion 10 projecting horizontally from the vertical member 8 and joining the horizontal member 9 between the pieces is formed in a loop from the upper horizontal member 9 to the horizontal member 9 immediately below, and The joint portion 10 is formed by connecting the cross member 9 to the left and right staggers. Note that the length of the uppermost portion and the lowermost portion of the continuous horizontal member 9, which protrudes horizontally from the vertical member 8 on the opposite side to the joint portion 10, is required to be equal to the joint length with each piece. It is.

Further, the loop shape of the joint portion 10 enhances the easiness of stacking of the joint portion 10 and the joint strength of each piece of the lattice plane members 5, 6, 7 when the wall 4 described later is constructed. For this reason, it is formed in an arc shape, but may be formed in a polygonal shape.
Alternatively, only the end portion of the joint portion 10 previously formed into an arc-shaped loop may be manufactured and placed, and then welded to the cross member 9 to be integrated. The fixed lattice plane 5 is provided with only the vertical members 8 standing upright to connect the lattice-like portion having the five joints 10 on the left and right sides and the wall 4 between the first floor and the second floor. It consists of the part which did.

Next, the lattice plane member 6 shown in FIG. 2B will be described. At the time of constructing the wall 4 to be described later, the lattice planar body 6 shifts the joint positions of the pieces of the lattice planar bodies 5, 6, 7 in the longitudinal direction of the wall so that the joints 10 do not come to the same position. It is used for adjusting the length of the wall in the vicinity of the columns 3 and 3 to maintain the strength.

The lattice plane 6 is formed of the above-mentioned regular lattice plane 5.
The size is reduced to half, and five vertical members 8 are arranged at equal intervals. The horizontal member 9 projects horizontally from the vertical member 8 like the standard lattice plane member 5 and is formed in an arc-shaped loop in a staggered right and left direction. At the same time, the upper part of the vertical member 8 is
Similarly, only the vertical member 8 is erected vertically. The structure of the intersection 9a between the vertical member 8 and the horizontal member 9 and other portions are the same as those of the regular lattice plane member 5.

Next, a description will be given of the pillar fixing lattice plane 7 fixed to the pillars 3 and 3 shown in FIG. 2 (c). The column fixing lattice plane 7 is formed by welding one of the vertical members 8 and the horizontal member 9 in a lattice shape at intersections 9a at equal intervals in the vertical direction. The cross members 9 project from the vertically parallel portions having a length fixed to the columns 3 and 3 and the vertical members 8, and form the cross members 9 into an arc-shaped loop to form each of the lattice plane members 5, 6. Joint part 10 that overlaps with joint part 10
Are formed to have five. In addition, the projecting portion of the upper horizontal member 9 from the vertical member 8 is required for the bonding length of the lattice planes 5 and 6 to be bonded to the horizontal member 9. In addition, the length of the upper vertical member 8 is also set up vertically by the length necessary for connection with the upper wall 4 as described above.

Next, according to FIGS. 1A and 1B, the wall 4
The construction method will be described. After constructing the pillars 3,3, the required number of the lattice planes 5,6 manufactured in the factory at the construction site of the wall 4
7 is carried in by a lifting machine (not shown). Thereafter, a pair of the joint fixing portions 10 are disposed inside the pillars 3 and 3 toward the outside of the pillars 3 and 3 with one piece of the grid fixing lattice-shaped body 7 spaced apart according to the design wall thickness. The columns 3, 3 and the cross members 9, 9,... Are appropriately bound by a wire (not shown) or the like so as not to be displaced.

Next, the joint portion 10 of one of the pillar fixing lattice planar members 7 and the joint portion 10 of the fixed lattice planar member 5 are overlapped and positioned so as to secure a circular shape. One piece of the regular lattice plane 5 is disposed. The joint 10
It is sufficient for the overlapping portions of the competitors to be tied every other place with the wire 11 or the like. In order to shift the position of the joint portion, the joint portion 10 of the other pillar fixing lattice planar member 7 is overlapped with the joint portion 10 of the lattice planar member 6 so as to secure a circular shape, and the positioning is performed. Then, one piece of the lattice planar body 6 is provided. The joints of the overlapping portions of the joint portions 10 are bound at every other position by the number line 11 or the like as described above.

In the case where the regular lattice plane 5 and the lattice plane 6 are erected, spacers 12 to be described later are sometimes added to the regular lattice plane 5 in order to secure a wall thickness. Horizontal material 9
And the cross member 9 of the lattice plane member 6 is engaged to perform positioning. Thereafter, one piece each of the next fixed lattice planes 5 and 5 is disposed in the longitudinal direction of the fixed lattice plane body 5 and the wall 4 of the lattice plane body 6, respectively. Are overlapped so as to ensure a circular shape, and a wire 11

In order to adjust the length of the wall 4 at the joint portion with the column fixing grid plane member 7 disposed at a predetermined position, a piece of the grid plane body 6 is erected at a position opposite to the other column and fixed. Is formed.

Each piece of the lattice planes 5 and 6 is
When the pieces are extended in the longitudinal direction, it takes too much time to alternately stack the pieces, and thus, when the pieces are overlapped from one side in order as shown in the figure, the time required for the work is reduced. Further, since the joint portions 10 of the respective pieces are provided in a staggered manner on the left and right sides, the joining between the pieces is disposed on the back side for each piece, and the joining is performed such that the loops of the joint portions 10 overlap.

FIG. 1 (c) shows another embodiment of the plane of the wall 4 shown in FIG. 1 (b).

As shown, one pillar 3 moves to the other pillar 3
The arrangement of the lower lattice planes 5 and 6 and the overlapping position in the wall thickness direction are formed the same as in FIG. 1B, but the upper lattice planes facing the wall thickness direction are arranged in the same manner. The superposition position of the bodies 5 and 6 in the wall thickness direction is performed outside the lattice plane body 6 opposite to the one shown in FIG. Hereinafter, the overlapping position of the next regular lattice planar body 5 to be arranged is sequentially performed outside.

The positional relationship between the front and back surfaces of the regular lattice planes 5, 5,... Facing the wall thickness direction is the same as in FIG.

Also, the fixed lattice planar bodies 5, 5 facing each other.
The spacers 12 that are positioned in some places are disposed between them.

FIG. 3 shows a spacer 1 for maintaining the wall thickness.
2 is made of resin or metal.

In order to arrange the pieces of the lattice planes 5, 5 at a predetermined interval L, the engaging portions 14, 14 on both sides are pulled to the reinforcing bar of the cross member 9 of the lattice planes 5, 5. Hang and attach.
The engaging portions 14, 14 are formed by three large, medium, and small circles communicating with the openings 14a, 14a so as to be able to engage with reinforcing bars of three different sizes. It can be used for different places. The engaging part 14, 1
In order to maintain a distance L at substantially the center between the four members 4, they are connected by a member 13 and integrated. Since the spacer 12 is merely for maintaining the interval L, the thickness T may be thin and may be manufactured by punching. After arranging the pieces of the lattice planar bodies 5, 6, 7,... Between the columns 3, 3, a formwork (not shown) is assembled on the outside of each piece in accordance with the design wall thickness. A wall is formed between the rooms by filling concrete in the formwork.

It should be noted that the shape, size, number of vertical members and horizontal members, etc. of the lattice plane shown in the embodiment are not limited to these, and may be appropriately changed depending on the design of the wall. Further, although the embodiment has been described with respect to the construction of the wall, it can be used in the construction of the slab. In this way, by arranging the lattice planes 5, 6, 7,... Efficiently, the construction of the wall 4 becomes simpler than the conventional work.

The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified ones.

[0027]

According to the present invention, the joints of the lattice planes are formed in a loop shape, and the joints are overlapped and joined to each other, whereby the mutual positioning of the lattice planes can be facilitated, and the binding points In addition to reducing the number of materials used, the joint material can be saved and the joint strength can be ensured. In addition, since the end of the joining portion is formed in a loop shape, the worker can safely work without being injured by the protrusion of the end in assembling the lattice plane body or the like. Further, since the end portions of the lattice planes are formed with a loop-like joint in a staggered right and left direction, a plurality of lattice planes can be efficiently arranged and joined when joining. In addition, a column fixing grid surface having a loop-shaped joint portion on the column is provided, and the material used for the joint portion is reduced by polymerization with the joint portion of the grid surface member, thereby securing joint strength. The joining operation can be easily performed.

The same effect can be obtained in the joining operation of the lattice planes continuously arranged. Therefore, while reducing the material cost of the joint part, the man-hour for the joint part is reduced, the construction period is greatly shortened in wall construction, and it contributes to the cost reduction of the construction cost. This is an invention having a great effect.
