Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an extrusion cement board mounting structure for mounting a large panel made of a plurality of extrusion cement boards to a housing.
[0002]
[Prior art]
Extruded cement boards with excellent durability and design are often used for exterior walls of buildings as exterior boards.
By the way, horizontal relative displacement, that is, interlayer displacement, occurs between a certain floor and the floors adjacent to the top and bottom thereof due to horizontal external forces such as earthquake and wind. For this reason, conventionally, each of the extrusion-molded cement boards is attached to the casing by soft joining without being rigidly joined one by one. Thereby, the interlayer displacement of the exterior board could be absorbed between the casings, that is, the flexible joint.
[0003]
However, it takes a lot of labor to attach the extruded cement plates one by one directly to the surface of the casing. In particular, in the case of a multi-story building, the transportation work to the upper floor becomes difficult. In addition, joint construction and painting construction after mounting the extrusion-molded cement board must all be performed on the outer wall of the frame, which increases the construction on site and hinders the shortening of the work period.
[0004]
Therefore, a large-sized panel 3 composed of a plurality of extruded cement plates 1 shown in FIG. 10 is manufactured in advance, and a plurality of extruded cement plates 1 are attached to the housing in units of large panels. Was proposed. In this mounting structure, individual extruded cement plates 1 are rigidly joined with bolts via a base material 5 mounted on a rectangular frame, and a large panel 3 having integral rigidity is manufactured. The large panel 3 is softly joined with bolts to a primary fastener 10 attached to a housing as shown in FIG. 11 via a secondary fastener 9 attached to the frame on a panel basis.
[0005]
[Problems to be solved by the invention]
However, the conventional extruded cement board mounting structure that attaches multiple extruded cement boards to the chassis in units of large panels is a rigid joint where individual extruded cement boards are joined together via a base material. In order to manufacture as a large panel having, the interlayer displacement had to be absorbed between the large panels. For this reason, large-sized large panels must have a structure that can be flexibly joined to the housing, and high strength is required. Therefore, the members, frames, and the like constituting these flexible joints are large and heavy. As a result, the weight of the large panel is further increased, and there is a problem that workability is lowered. In addition, since a flexible joint that can absorb a large amount of displacement and can withstand a large weight must be formed, there is a problem that the mounting structure becomes complicated and adjustment and mounting work becomes troublesome.
The present invention has been made in view of the above situation, and an extrusion molding in which a plurality of extrusion-molded cement boards can be attached at one time and can absorb interlayer displacement without forming a large-weight, high-strength frame and flexible joint. It aims at providing the attachment structure of a cement board.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, an extruded cement board mounting structure according to the present invention is an extruded cement board mounting structure for mounting a large panel composed of a plurality of extruded cement boards to a housing, and is arranged in the same plane. Further, a base material extending over all of the extruded cement plates is arranged on one surface of the plurality of extruded cement plates, and the other end of the lightning bolt metal fitting one end fastened to the extruded cement plates and the extruded cement. The base material is sandwiched and fixed with a plate, and the plurality of extrusion-molded cement plates are assembled as an integrated large panel without being rigidly bonded to the base material, and the base material is directly or according to a necessary pitch. The large panel is attached to the casing by being rigidly joined to the casing via a connecting member.
[0007]
In this extrusion-molded cement board mounting structure, a plurality of extrusion-molded cement boards are softly bonded to the base material, and an integrated large panel is assembled. And a large sized panel is attached to a housing because a base material is rigidly joined to a housing. Therefore, interlayer displacement is absorbed between the extruded cement board and the base material. Thereby, it is not necessary to form a frame and a flexible joint that can withstand a large weight for absorbing interlayer displacement between the large panels for each large panel.

[0009]
In the extruded cement board mounting structure according to this embodiment, a large panel 15 shown in FIG. 1 in which a plurality of extruded cement boards 11 are integrally assembled with a base material 13 is used.
That is, each extrusion-molded cement board 11 is formed in a rectangular shape. In this example, five extruded cement plates 11 are arranged in the same plane (vertical plane) so that the long sides are adjacent to each other. On one surface (back surface) of the extruded cement board 11, a pair of parallel base materials 13 extending over all the extruded cement boards 11 are arranged.
[0010]
One end of a lightning bolt 19 is fastened to the back surface of the extruded cement board 11 with a bolt (not shown). As the base material 13, equilateral angle steel is used. The lightning bolt 19 is clamped at one end, and a part 13 a of the base material 13 is sandwiched and fixed between the other end and the back surface of the extruded cement board 11. That is, the extrusion-molded cement board 11 and the base material 13 are softly joined. Thus, the plurality of extruded cement plates 11 are assembled as a single large panel 15 without being rigidly joined to the base material 13. In FIG. 1, reference numeral 20a denotes an intermediate portion, and 20b denotes a supporting means for supporting the lowermost extruded cement board 11.
[0011]
As for this large sized panel 15, each base material 13 is attached to a housing in the lower part A, the upper part C, and the bracket part which are shown in FIG. Although not shown in FIG. 1, the necessary number of bracket portions are attached at a predetermined pitch.
[0012]
In the lower part A, as shown in FIGS. 2 and 3, a secondary fastener 21 made of equilateral angle steel is welded and fixed to the base material 13 in a direction perpendicular to the back surface of the extruded cement plate 11. On the other hand, a long primary fastener 25 made of equilateral angle steel is welded and fixed to the column 23 which is a casing in the direction in which the longitudinal direction is perpendicular to the back surface of the extruded cement plate 11.
[0013]
On the horizontal piece 25a of the primary fastener 25, a bolt 26 whose head is welded to the horizontal piece 25a is erected in the vertical direction so that the tip is on the upper side. An insertion hole 27 having an inner diameter sufficiently larger than the diameter of the bolt 26 is formed in the horizontal piece 21 a of the secondary fastener 21. A receiving nut 29 is screwed onto the bolt 26 at an appropriate intermediate position. On the receiving nut 29, a square seat 31 inserted through the bolt 26 is placed. On the corner seat 31, a horizontal piece 21 a of the secondary fastener 21 inserted through the insertion hole 27 through the bolt 26 is placed. A square seat 31 is further placed on the horizontal piece 21a, and a tightening nut 33 is screwed thereon.
[0014]
That is, the horizontal piece 21 a of the secondary fastener 21 is sandwiched and fixed by the receiving nut 29 and the fastening nut 33 through the square seat 31, and as a result, is fixed to the column 23 through the bolt 26 and the primary fastener 25. The secondary fastener 21 is moved in the vertical direction by the rotation of the receiving nut 29 so that the support position can be adjusted. As will be described in the work procedure of the extrusion-molded cement plate mounting structure described later, the fastening nut 33, the square seat 31, and the secondary fastener 21 are welded and fixed after adjustment. That is, the base material 13 is finally rigidly joined to the column 23.
[0015]
In the upper part C, as shown in FIG. 4, a secondary fastener 35 made of equilateral angle steel is welded and fixed to the base material 13 in a direction perpendicular to the back surface of the extruded cement plate 11. On the other hand, a primary fastener 37 made of equilateral angle steel is fixed to the column 23 by welding. A connection hole 39 is formed in the secondary fastener 35 and the primary fastener 37. The secondary fastener 35 and the primary fastener 37 are connected by a turnbuckle 41 that is locked to the connection holes 39. Accordingly, in the upper part of the large-sized panel 15, the projecting dimension in the horizontal direction from the housing is adjusted by adjusting the turnbuckle 41. In addition, 43 in FIG. 4 shows the panel suspension hole at the time of lifting the large sized panel 15 with a hoist etc. FIG.
[0016]
In the bracket portion, as shown in FIGS. 5 and 6, a connecting material (secondary fastener) 45 made of equilateral angle steel is welded and fixed to the base material 13. On the other hand, a long connecting material (primary fastener) 47 made of equilateral angle steel is welded and fixed to the column 23 in a direction perpendicular to the back surface of the extruded cement plate 11.
[0017]
The secondary fastener 45 is welded and fixed between the base material 13 and the primary fastener 47 after the adjustment of the lower part A and the upper part C of the large panel 15 is completed. Therefore, in the large panel 15, the base material 13 is finally rigidly joined to the column 23 by the bracket portion. Although not shown, the required number of the bracket portions are attached at a predetermined pitch.
[0018]
In addition, although the lower part A and the upper part C are soft junction, this is for absorbing the position shift only at the time of attachment, and the conventional flexible joint structure for absorbing the interlayer displacement permanently. Is different. Therefore, a simple structure may be used, and the structure can be reduced in size and strength as compared with a conventional permanent flexible joint structure.
[0019]
Next, the working procedure of the mounting structure of the extruded cement board will be described.
First, a plurality of extruded cement boards 11 are assembled as a single large panel 15 that is softly joined to the base material 13 using a lightning bolt 19 and is not rigidly joined.
At the upper part C of the large panel 15, a hoisting machine hook or the like is hooked in the panel suspension hole 43 of the secondary fastener 35 that has been welded and fixed to the base material 13 in advance, so that the large panel 15 is placed at a predetermined position of the casing. lift.
[0020]
In the large panel 15, the secondary fastener 21 is fixed to the base material 13 by welding in the lower part A in advance. Further, a primary fastener 25 is welded and fixed to the column 23 in advance at a position corresponding to the secondary fastener 21.
The large panel 15 first supports the lower portion A on the housing side by inserting the insertion hole 27 of the secondary fastener 21 into the bolt 26 fixed to the primary fastener 25.
Next, the secondary fastener 35 welded and fixed to the base material 13 of the upper part C and the primary fastener 37 welded and fixed to the column 23 are connected by a turnbuckle 41 and suspended by a hoist. No longer needed.
[0021]
Next, the receiving panel 29 and the turnbuckle 41 on the lower part A and the upper part C are adjusted to position the large panel 15.
Thereby, the large panel 15 is in a state where the lower part A and the upper part C are temporarily fixed to the column 23.
When the positioning is completed, first, the fastening nut 33, the square seat 31, and the secondary fastener 21 in the lower part A are welded and fixed.
Next, in the bracket portion, the primary fastener 47 that has been welded and fixed to the column 23 in advance and the base material 13 are welded and fixed by the secondary fastener 45.
[0022]
Thereby, the large panel 15 is rigidly joined between the base material 13 and the column 23, and the attachment to the housing is completed.
[0023]
In addition, before the large panel 15 is attached to the housing, joint construction and painting construction can be completed in units of the large panel 15 in advance. In this case, it is only necessary to perform joint construction between the large panels 15 after being attached to the housing.
[0024]
In this extrusion-molded cement board mounting structure, the extrusion-molded cement board 11 and the base material 13 were softly joined using a lightning bolt 19, and an integrated large panel 15 was assembled without rigid joining. On the other hand, the base material 13 was rigidly joined to the column 23 which is a casing by welding. That is, the interlayer displacement can be absorbed between the individual extruded cement plates 11 and the base material 13.
As a result, there is no need to form a flexible joint for each large panel 15 that can withstand a large weight and absorb a large amount of displacement, and the members, frames, and the like can be made small and lightweight.
[0025]
In addition, a plurality of extrusion-molded cement plates 11 can be collectively attached to the housing, and joint construction and painting construction associated therewith can be performed in advance.
Furthermore, since there is no flexible joint having a complicated structure that can withstand a large weight, adjustment and mounting work can be facilitated, and workability can be improved.
[0026]
Next, the modification of the mounting structure of the extrusion-molded cement board concerning this invention is demonstrated.
FIG. 7 is a plan view showing the height adjustment part of the large panel, FIG. 8 is a plan view showing the horizontal position adjustment part of the large panel, and FIG. 9 is a plan view showing the bracket part mounting part of the large panel.
In the height adjustment portion of the large panel 15 shown in FIG. 7, a secondary fastener 51 made of equilateral angle steel is welded and fixed to the base material 13 in a direction perpendicular to the back surface of the extruded cement plate 11. On the other hand, a long primary fastener 53 made of equilateral angle steel is welded and fixed to the column 23 in a horizontal direction parallel to the back surface of the extruded cement plate 11.
[0027]
On the horizontal piece 51a of the secondary fastener 51, a bolt 26 is vertically suspended so that a tip is on the lower side of a nut whose head is welded to the horizontal piece 51a. In this state, the tip of the bolt 26 rests on the horizontal piece 53a.
Therefore, the secondary fastener 51 moves in the vertical direction by the rotation of the bolt 26, and the support position can be adjusted.
[0028]
In the horizontal position adjustment section of the large panel 15 shown in FIG. 8, the secondary fastener 55 made of equilateral angle steel is arranged so that both pieces face the vertical direction, and one vertical piece 55a is welded and fixed to the base material 13. is there. On the other hand, a primary fastener 57 made of equilateral angle steel is arranged on the column 23 so that both pieces are oriented in the vertical direction, and one vertical piece 57a is welded and fixed to the column 23 via an intermediate member 59. Insertion holes 61 and 62 are formed in the secondary fastener 55 and the primary fastener 57. The secondary fastener 55 and the primary fastener 57 are inserted through the insertion holes 61 and 62 with bolts 63 and sandwiched and fixed by nuts 65. The vertical pieces 57b are provided with push bolts 63. Therefore, the horizontal position adjustment part of the large panel 15 is configured such that the protruding dimension in the horizontal direction from the housing is adjusted by adjusting the push bolt 63.
[0029]
The insertion hole 62 is formed with an inner diameter sufficiently larger than the diameter of the bolt 65a. Accordingly, the nut 65 is configured to fasten the vertical piece 57b via the square seat 31. The push bolt 63 pushes the secondary fastener 55. Thereby, the position shift of the secondary fastener 55 and the primary fastener 57 at the time of attachment can be absorbed.
[0030]
In the bracket portion of the large panel 15 shown in FIG. 9, a connecting material (secondary fastener) 69 made of equilateral angle steel is arranged so that both pieces are directed in the vertical direction, and one vertical piece 69 a is welded to the base material 13. It is fixed. On the other hand, one vertical piece 71 a of a connecting material (primary fastener) 71 made of equilateral angle steel is fixed to the column 23 by welding. The other vertical piece 69 b of the secondary fastener 55 is welded and fixed to the other vertical piece 71 b of the primary fastener 71.
[0031]
After the adjustment of the height and the horizontal direction of the large panel 15 is completed, the secondary fastener 69 is welded and fixed between the base material 13 and the primary fastener 71 according to the required pitch. Therefore, in the large panel 15, the base material 13 is rigidly joined to the column 23 by the bracket portion.
[0032]
Also with this extrusion-molded cement board mounting structure, interlayer displacement can be absorbed between the individual extrusion-molded cement boards 11 and the base material 13, as in the above-described extrusion-molded cement board mounting structure. As a result, there is no need to form a flexible joint that can withstand a large weight, and the members, frames, and the like can be made small and lightweight.
[0033]

Thereby, interlayer displacement can be absorbed between the individual extruded cement boards and the base material. As a result, there is no need to form a flexible joint that can withstand a large weight for each large panel, and the members, frames, etc. can be made small and lightweight. Moreover, a plurality of extrusion-molded cement boards can be collectively attached to the housing, and joint construction and painting construction associated therewith can be performed in advance. Furthermore, since there is no flexible joint having a complicated structure that can withstand a large weight, adjustment and mounting work can be facilitated, and workability can be improved.
