DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a wall of a building and a panel unit used for the method.

[0002]

2. Description of the Related Art As is well known, the construction of an outer wall in a low- to middle-rise building is generally performed by a dry construction method in which various wall plates are attached to a skeleton. Various materials and forms such as cement plates, slate plates, and metal plates are used as wall plates in the dry method, but recently, sandwich panels having a configuration in which steel plates are attached to both front and back surfaces of a core material have been used. Because they are lightweight, easy to handle, and inexpensive, they have been widely used as outer wall materials for relatively low-cost buildings such as store buildings and warehouses.

[0003] In the construction of the outer wall by such a dry method, first, a rim as a wall base material is attached to the skeleton, and a wall plate is attached to the rim by fastening or welding. Becomes In that case, the installation position of the body edge to the skeleton and the form of attachment of the wall plate to the body edge differ depending on the material, shape, and dimensions of the wall plate.For example, when adopting a horizontally long sandwich panel as the wall plate, Usually, several vertical waist edges are required for one panel, and each of the sandwich panels is screwed and attached to the plurality of vertical waist edges.

[0004]

However, in the case where the outer wall is formed by the sandwich panel as described above, the work of attaching a large number of vertical trunks to the frame firstly requires a great deal of work. Since the mounting accuracy of the vertical torso to the skeleton directly affects the finishing accuracy of the outer wall, it is necessary to accurately output the streets of each vertical torso, so that the work must be troublesome and require careful attention. Absent. In addition, the work to attach the sandwich panel to the many vertical rims attached to the frame in this way is not only inefficient because of the large number of screwing points, but also because of the external work required for that work. It is essential to set up a working scaffold.

[0005] The above is a problem that arises more or less not only in the case where the outer wall is constructed by sandwich panels, but also in the dry construction method in which various wall panels are attached to the frame through the rim. An effective measure that can be performed more easily and accurately has been desired.

[0006]

SUMMARY OF THE INVENTION In view of the above circumstances, the construction method of the present invention, when constructing a wall of a building, comprises a panel unit formed by connecting a plurality of panel-shaped wall plates with a plurality of connecting members.

The present embodiment is a construction method for forming an outer wall of a building using the above-described sandwich panel, but a vertical body edge is attached to a body in advance and a sandwich is provided for the vertical body edge as in the related art. Instead of attaching one panel at a time, a panel unit is formed by connecting a plurality of sandwich panels on the ground in advance with a connecting material serving as a vertical fuselage, and the panel units are lifted at once to form a frame. It is intended to be attached to.

As shown in FIG. 1, a panel unit 1 according to the present embodiment has a plurality of (six in this example) horizontally long sandwich panels 2 arranged vertically and a plurality of (three in this example) sandwich panels.
This is a form connected by a long connecting material 3. In this embodiment, square steel pipes are used as the connecting members 3, and each of the sandwich panels 2 is connected to the connecting members 3.
Are fixed by screws. These connecting members 3 not only connect the respective sandwich panels 2 but also function as vertical frame edges as they are fastened to the building frame as described later.
The dimensions of the entire panel unit 1 and the dimensions of the individual sandwich panels 2 and the number of connections thereof may be appropriately set according to the scale and form of the building to be constructed, and are not particularly limited. However, it is appropriate that the overall height dimension of the panel unit 1 is equivalent to, for example, one to two levels of a building, and the width dimension is equivalent to, for example, half a span to one span of a building. . Further, the material, cross-sectional shape, dimensions, required number, installation interval, and the like of the connecting member 3 can secure such a strength that the panel unit 1 can be lifted without hindrance when the panel unit 1 is mounted on a skeleton. After the unit 1 is attached to the skeleton, it may be determined so that the unit 1 can function as a vertical waist without trouble.

The construction method of the present embodiment using the panel unit 1 will be described in detail below.

First, the panel unit 1 is assembled in a work yard on the ground. As shown in FIG. 2, a plurality (three in the illustrated example) of gantry 4 are laid in parallel in a sufficiently horizontal and flat work yard.
The above-mentioned connecting members 3 are horizontally placed on the connecting members 3, and the sandwich panels 2 are sequentially arranged on the connecting members 3 and fixed by screws. A positioning tool 5 is provided on the upper surface of each mount 4 in advance.
Are fixed, and the connecting members 3 are
Is positioned so that each connecting member 3 is naturally positioned at an appropriate position. A positioning ruler 6 is provided around the gantry 4 so as to extend in two directions orthogonal to each other.
(Indicated by a dashed line), and the positioning ruler 6
It is preferable that the end of the connecting member 3 or the one end of the sandwich panel 2 be abutted against the side surface of the connecting member 3 so that the positioning of the connecting member 3 or the sandwich panel 2 is appropriately performed. By doing so, the panel unit 1 can be easily and accurately formed without being distorted or deformed. In addition, as the gantry 4 and the positioning ruler 6, an appropriate steel material (for example, a square pipe material or a pre-made steel material for a ridge) may be diverted.

After the panel unit 1 is formed as described above, a hanging member 7 is connected to the upper part thereof as shown by a chain line in FIG. Then, the panel unit 1 is attached to the frame by fastening the connecting member 3 to the frame.

The connection member 3 can be fastened to the frame in any suitable form. In this embodiment, the fastening is performed as shown in FIGS. That is, the bolts 8 as mounting hardware are respectively protruded to the back side (building side) near the upper end and the lower end of the connecting member 3 and fixed in advance by welding or the like, and the building frame (in this example) On the floor slab), mounting hardware 9 is previously mounted at a position corresponding to the installation position of the bolts 8. The mounting hardware 9 in the present example is an angle-shaped metal that is fixed to the skeleton by a hole-in anchor,
Vertical grooves 9b corresponding to the bolts 8 are formed in the wall portion 9a, and the entire panel unit 1 can be supported by engaging the bolts 8 with the vertical grooves 9b. The bolt 8 engaged with the vertical groove 9b
By screwing a nut 12 through a washer 11 and tightening the panel unit 1, the panel unit 1 is firmly fastened to the skeleton while being supported by a mounting hardware 9 via a bolt 8. 3 directly functions as a vertical waist edge. The upper portion of the vertical groove 9b formed in the mounting hardware 9 is formed as a tapered wide portion 9c so that the bolt 8 is guided by the wide portion 9c so as to be easily dropped into the vertical groove 9b. Has become. FIG.
Reference numeral 14 in FIG. 4 denotes a reinforcing angle member previously attached to the skeleton (floor slab), and reference numeral 15 in FIG. 4 denotes a lock for closing a gap between the floor slab and the panel unit to form a fire protection section. Wool.

As described above, the outer wall of the building is formed by mounting the panel unit 1 on the frame and similarly mounting other panel units 1 on the left, right, up and down without any gap. In addition, as shown in FIG.
It is preferable to connect the connecting members 3 of the panel units 1 connected vertically via the attachment plate 13. Also, joints (vertical joints and horizontal joints) between the panel units 1 as necessary.
Should be provided.

According to the construction method of this embodiment, a plurality of sandwich panels 2 and a plurality of connecting members 3 are pre-assembled to form a panel unit 1, which is lifted all together and attached to a frame. Therefore, the work efficiency can be remarkably improved as compared with the conventional construction method in which each sandwich panel 2 is attached one by one, and an external work scaffold conventionally required is not required. Can be. Moreover, since the connecting member 3 for connecting the sandwich panels 2 is used as it is as the vertical body edge, the work of attaching the vertical body edge to the frame, which conventionally required high accuracy, can be substantially omitted. It is. Of course, in the present construction method, the assembling work of the panel unit 1 can be easily performed in the work yard on the ground, and therefore, the accuracy of the panel unit 1 itself can be easily ensured.

An embodiment of the present invention has been described above.
The present invention is not limited to the above, and various design modifications are possible. For example, in the above-described embodiment, the mounting hardware 9 in which the bolt 8 previously fixed to the connecting member 3 is mounted on the skeleton side.
And the panel unit 1 is supported and fastened in that state, so that the panel unit 1 can be easily attached to the frame and can bear the weight of the panel unit 1 by its own weight. And the strength against the out-of-plane force (the force acting to separate the panel unit from the building) can be sufficiently secured. However, the form of attachment of the panel unit 1 to the skeleton is not limited to the above, and is appropriate. For example, the connecting member 3 may be directly locked or fastened to the beam or the column, or the connecting member 3 may be directly welded to the frame if there is no problem. It does not hinder.

FIGS. 6 and 7 show another preferred example of the mounting structure of the panel unit 1 to the frame. In this case, a mounting hardware 20 having a mechanism capable of more securely bearing the weight of the panel unit 1 and performing vertical positioning is used. That is, the mounting hardware 20 used in the present embodiment has the plate material 21 welded to the upper part of the wall 9a of the angle material as the mounting hardware 9 in the above-described embodiment, and the connecting material 3 of the panel unit 1 has the plate material 21 attached thereto. The angle member 22 is welded to a position above the member 21 so as to face the same, and the angle member 22 is welded.
, A level adjusting bolt 23 is screwed downward.
In addition to engaging the tip of the bolt 8 welded to the connecting member 3 with the groove 9b of the mounting hardware 9 as in the above embodiment, the tip of the level adjusting bolt 23 is , The weight of the entire panel unit 1 can be more strongly received by the plate member 21 via the angle member 22 and the level adjusting bolt 23. Also, the level adjustment bolt 23
By simply adjusting the screwing amount of the panel unit 1, the vertical positioning of the panel unit 1 with respect to the skeleton can be easily performed, and the mounting work of the panel unit 1 can be further improved. Of course, the out-of-plane force acting on the panel unit 1 is borne by the engagement between the bolt 8 and the mounting hardware 9 without any trouble, as in the case of the above embodiment.

Still another example of the structure for attaching the panel unit 1 to the frame is shown below. 8 employs angle members 30 instead of the bolts 8 in the above-described embodiment as mounting hardware to be attached to the connecting member 3 and welds the angle members 30 to both sides of the connecting member 3. The angle member 30 is supported and fixed to the mounting hardware 9 via a bolt 31. 9 is applied to the end of the panel unit 1, in which the angle member 30 is attached to only one side of the connecting member 3, and the mounting hardware 9 is also halved. The bolt 8 in the above-described embodiment is inconvenient and may be bent at the time of transportation because it protrudes largely from the connecting member 3. However, such a situation is improved by adopting the angle member 30 as described above. be able to.

FIG. 10 is similar to FIG. 6 and FIG.
In place of the plate member 21 of the mounting hardware 20 shown in FIG. 6, a mounting hardware 32 to which a long nut 33 is welded is employed, and the head of a positioning adjustment bolt 34 screwed to the long nut 33 is brought into contact with the lower surface of the angle material 22. Thus, the panel unit 1 receives its own weight and performs vertical positioning.

FIG. 11 shows an example in which one panel unit 1 is mounted by using the above three types of mounting structures in combination, and two upper intermediate portions are shown in FIG.
), And the upper and lower four places on both sides are shown in FIG.
IX), and the two lower intermediate portions have the structure (shown by the symbol X) shown in FIG.

In the above embodiment, since the sandwich panel 2 is used as the wall plate and the panel unit 1 using the square steel pipe as the connecting member 3, the panel unit 1 is used.
Although the panel unit 1 can be made sufficiently lightweight and inexpensive and have sufficient strength, it is particularly suitable for application to the outer wall construction of a relatively low-cost building.
The present invention is of course not limited to the above embodiment,
Not only the sandwich panel 2 but also a panel-shaped wall plate of various materials, forms and dimensions can be used in the same manner, and the connecting member 3 is not limited to a square steel pipe, but may be a channel material or an H-shaped steel. As long as the required strength can be ensured, not only steel materials of other cross-sectional shapes but also other materials such as aluminum materials can be adopted. Naturally, the attachment of the wall plate to the connecting member 3 is not limited to screwing. What is necessary is just to select the optimal form.

When an opening such as a window or an air supply / exhaust port is provided on the wall surface, such an opening may be formed when assembling the panel unit 1, and if possible, a fitting and the like are assembled. You just have to put it in. Of course, the present invention can be applied not only to the outer wall construction but also to the construction of a wall plate as a partition wall or an exterior finishing material (for example, a case where a panel-like wall plate is attached as a finishing material to the surface of a concrete outer wall). ) Can be applied in the same manner.

Further, in the above embodiment, the panel unit 1 is assembled in the work yard at the site when the wall surface is constructed. However, the panel unit 1 may be manufactured in advance in a factory, and may be carried to the site and used. Of course, in this case, if the panel unit 1 is mass-produced according to a predetermined standard, the cost can be further reduced.

[0024]

As described above, according to the construction method of the present invention, a panel unit in which a plurality of panel-shaped wall plates are connected by a plurality of connecting members is assembled in advance, and the panel unit is lifted and guided to an installation position. Since the connecting material is attached to the building frame as a vertical frame, the vertical frame and a large number of wall panels can be simultaneously mounted simply by attaching the connecting material to the frame, Therefore, the work efficiency of wall construction can be significantly improved, and the need for external work scaffolds can be eliminated.Moreover, it has an excellent effect that construction accuracy can be easily secured. It is suitable. In particular, if a fitting that can be engaged with each other is attached to the connecting member and the skeleton in advance, and the panel unit is supported by the skeleton and fastened by the engagement thereof, the panel unit mounting work can be performed. There is an advantage that it can be performed more easily and reliably. In addition, if the mounting hardware has a strength capable of bearing the weight of the panel unit and an out-of-plane force and can adjust the vertical positioning of the panel unit, the mounting strength of the panel unit can be further increased. In addition, the mounting work can be performed more easily.

The panel unit according to the present invention is formed by connecting a plurality of panel-shaped wall plates serving as wall surfaces of a building in advance with a plurality of connecting members serving as vertical frame edges of the building. It is suitable as a material used when carrying out the method, especially if a mounting material such as an angle material is attached to the connecting material, it can be easily attached to the skeleton, and a steel plate is attached to both sides of the core material as a wall plate. If a horizontally long sandwich panel is used and a steel material is used as a connecting material, there is an advantage that the material can be made sufficiently lightweight and inexpensive and have sufficient strength.
