Description

[Detailed Description of the Invention] This invention relates to a panel wall structure in which a wall surface is constituted by panels.

In the conventional panel wall structure, as shown in FIG. 1, for example, a flat aluminum plate 42 is pasted with adhesive on the surface of a fireproof panel 41, and a semicircular groove 43 is provided on the longitudinal side surface of the fireproof panel 41. The panels 44 are arranged with predetermined joint gaps, and the grooves 43
is filled with mortar M for bonding, and the backer 45
A caulking layer 46 was provided therebetween. However, during this construction, joint bars (boards) were installed in the joint gaps 48, 48 formed before and after the groove 43.
49 is inserted and sealed, mortar is poured into the groove 43, and after waiting for the mortar to harden, the joint bar 49 is removed, the backer 45 is inserted, and the caulking agent is filled with the backer 45 as the bottom. , these joint rod insertion/extraction operations,
The backer insertion work, caulking work, etc. were extremely complicated. Furthermore, since most of these works are carried out from the outside of the wall, it is necessary to erect scaffolding, and erecting high scaffolding, especially in high-rise buildings, is troublesome and time-consuming.

This idea solves the above-mentioned conventional drawbacks.
The purpose is to provide a panel wall structure that is easy to construct.

However, the gist of this invention is that a first gasket in the shape of a rectangular bar with a fitting part extending in the longitudinal direction such as a recessed groove on the surface side is attached to the side surface of a metal covering panel part attached to a fireproof panel. A plurality of fixed panels are arranged vertically and horizontally to form a horizontal joint gap and a vertical joint gap between the side surfaces, and between the first gaskets facing at the intersection of the horizontal joint gap and the vertical joint gap, A four-pronged second gasket is fitted on both sides facing the surface of the gasket, and the second gasket is provided with a fitting part that fits into the fitting part, and the two gaskets face each other at the horizontal joint gap and the vertical joint gap. Fitted between the first gaskets is a square rod-shaped third gasket, which has fitting portions on both sides facing the surface of the gasket to fit into the fitting portions of the gasket, and whose end reaches the second gasket. It is located in a panel wall structure characterized by a cladding.

An embodiment of this invention will be described below with reference to FIGS. 2 to 8.

A panel 1 for forming a flat wall is a composite fireproof panel in which a covering panel 3 such as an enamel panel is attached to a fireproof panel 2 such as a lightweight aerated concrete board. The covering panel 3 has a main plate part 4 facing the surface of the fireproof panel 2, and bent pieces 5, 5 continuous to the four circumferences of the main plate part 4, and has a box shape. A semicircular groove 7 is provided on the longitudinal side surface of the fireproof panel 2, and a sidewall portion 8 formed on the back side of the fireproof panel of this groove 7 is covered with a sidewall portion 9 formed on the front side of the fireproof panel. It is made to protrude laterally from the surface of the bent piece part 5. On the side surface of the panel 1, that is, on the surface of the bent pieces 5 and 6 of the covering panel 3, a first gasket 12 in the shape of a long and square bar having a groove-shaped fitting part 11 extending in the longitudinal direction on the front side is glued. It's fixed. As shown in the third figure, the first gasket 12 is formed by appropriately combining a rectangular bent body for a corner and a straight gasket, adhesively bonded to each other, and fixed to the panel 1 at a factory. Also the fourth
The corner panel 14 shown in the figure is also the same as the panel 1 above.
Similarly, a covering panel 3 is attached to a fireproof panel 2, but the main plate part 4 of the covering panel 3 has a bent plate shape, and bent pieces 6 are formed at the upper and lower ends of this main plate part.
The fireproof panel 2 has the same structure as the panel 1 in FIG. 3, except that it has an L-shape, and the groove 7 of the fireproof panel 2 is provided only on one longitudinal side surface. Portions or corresponding portions are designated by the same reference numerals as in FIG. 3. Further, the four-pronged second gasket 15 shown in FIG. 5 is provided with protrusions 17 on both side surfaces (wide surfaces) of each branch portion 16 to fit into the fitting portion 11 of the first gasket 12. . Further, the elongated third gasket 18 shown in the figure also has the same cross-sectional shape as the second gasket 15.
Each gasket 12, 15, 18 is made of a sealing material such as rubber or synthetic resin. The above-mentioned rubber is mainly made of specially modified rubber, and because it contains a hydrophilic part, when it comes in contact with water, it has a
It is also preferable to use water-swellable rubber that expands about 1.3 times.

In order to construct a panel wall at a building construction site using each of the above-mentioned members, first, as shown in Figure 6, the panel 14a at the left end in the figure with the first gasket 12 attached is assembled.
(The suffix a represents the first stage) is set up, and the third gasket 18 is fitted into the first gasket 12 in the horizontal joint gap 22 part on the upper side of the panel, and the third gasket 18 is similarly fitted in the vertical joint gap 21 part. Above first gasket 1
2 and fitting the third gasket 18 to
The second gasket 15 for the intersection 23 of the horizontal joint gap 22 between the first and second stage panels and the vertical joint gap 21 at the left end is fitted into the first gasket 12 at the upper right corner of the panel 14a. Next, attach the panel 1a to the right, and attach the end face of the side wall 8 to the panel 14a.
The first gasket 12 is fitted into the second gasket 15 and the third gasket 18 in the vertical joint gap 21 portion.
Similarly, the third gasket 1 for the horizontal joint gap is
8 on the upper side of the panel, a third gasket 18 for the vertical joint gap, and a second gasket 15 for the joint intersection part between the panels, respectively.
A are arranged horizontally one after another to form a first row of panels. If each panel 1, 14 is erected with the end surfaces of its side wall portions 8 abutting each other, a predetermined vertical joint gap 21 will be formed between the bent pieces 5, 5. Then the second
The panel 14b at the left end of the tier (subscript b indicates the second tier) is erected on the panel 14a of the first tier with a predetermined horizontal joint gap 22, and the horizontal joint gap 2 on the lower side is
Two-part third gasket 18 and second gasket 1
After fitting the first gasket 12 of the panel 14b to the panel 14b, the third gasket 18 for the horizontal joint gap (upper side) and the vertical joint gap (right side) and the joint intersection part ( upper right corner)
The second gasket 15 for
It is fitted into the gasket 12, and the same operation is performed for the panel 1b to form a panel wall. The third gasket 18 is cut to a length in which both ends (one end for the lowest vertical joint gap) reach the end surface of the branch part 16 of the second gasket 15 set at the joint intersection. Both gaskets 15 and 18 are fitted together while being bonded to each other with an adhesive. Note that, in principle, it is not necessary to use adhesive in the fitting portions between the first gasket 12, second gasket 15, and third gasket 18, but depending on the depth of the fitting portion, etc., adhesive may be used. good.

At the time of the above panel arrangement, the panels are attached to the building frame as follows. That is,
As shown in FIG. 7, the lower ends of the fireproof panels 2 of the panels 1 and 14 are supported by the brackets 27 attached to the angles 26 fixed to the building frame 25 via the brackets 28 as necessary. By adjusting the vertical joint and horizontal joint gaps, reinforcing bars 3 are placed in the cylindrical space 29 formed by the groove 7 on the side surface of the fireproof panel 2 of the adjacent panel, as shown in FIGS. 2 and 8.
0 is inserted, this reinforcing bar 30 is fixed to the receiving metal fitting 27, and the space 29 is filled with mortar M and solidified. At this time, since the space 29 is sealed by each gasket and the side wall portion 8 of the fireproof panel 2, mortar does not leak to the outside, and no joint bar is required. In addition, one end of the corner panel 14 is attached to a pillar 3 of the building via a mounting bracket 31.
It is attached to the building frame by a method of fixing it to the building frame.

As described above, simply by fitting the second gasket 15 and the third gasket 18 between the first gasket 12 and arranging the panels 1 and 14 in the vertical and horizontal directions, joints with sealing properties against rainwater are formed, and the grooves 7
This eliminates the need for the troublesome work of attaching and detaching joint rods for filling mortar into sections and for waiting for the mortar to solidify.

and the first gasket 12 at each joint.
and the second gasket 15 and the third gasket 1
8 is wide due to the fitting between the fitting portion 11 and the protrusion 17 and the surface contact between the surface of the first gasket other than these fitting portions and the side surfaces of the second and third gaskets opposing this. A contact area is formed, providing excellent sealing performance against rainwater. Moreover, excellent sealing performance can be obtained by the four-pronged second gasket 15 even at the intersection of the vertical joint and the horizontal joint.
Furthermore, since the first gasket 12 is fixed to the side surface of the metal covered panel section, the smooth side surface and the first gasket 12
There is little risk of rainwater entering between the gaskets, and good sealing performance is maintained.

Note that a caulking agent may be filled in the vertical joint gap 21 and horizontal joint gap 22 portions on the outside of each gasket 12, 15, 18 in order to further improve sealing performance. Further, the abutting surfaces of the second gasket 15 and the third gasket 18 may not be perpendicular to the longitudinal direction of the gasket.

FIG. 9 shows an embodiment in which a hollow portion 35 is provided in the third gasket 18. Since the third gasket 18 has a large amount of deformation in the joint width direction, it has the advantage that the permissible adjustment accuracy of the joint gap size can be increased. .

Further, in FIG. 10, a widened portion 36 having a width slightly wider than the joint gap dimension is formed in the third gasket 18, and a side surface 37 of the widened portion 36 is formed on the bent pieces 5 and 6 of the covering panel 3 when constructing a panel wall. An example is shown in which the sealing properties against rainwater are improved by abutting and sealing. Although it is aesthetically preferable that the outer surface of the widened portion 36 substantially coincide with the surface of the main plate portion 4 of the covering panel 3 as shown in the figure, it may be located inside the said surface as shown by the chain line in the figure.

The above shows the case where a concave groove is used as the fitting part 11 of the first gasket 12.
As shown in FIG. 2, the fitting portion 11 may be a convex strip. At this time, the third gasket 18 has a concave groove 3 on the side surface.
8 is provided and fitted into the fitting portion 11. 11th
The figure corresponds to FIG. 2, and FIG. 12 corresponds to FIG. 10, and corresponding parts are given the same reference numerals.

Although the third gasket 18 is illustrated in FIGS. 9 to 12 above, the second gasket 1
5 may also have a similar cross-sectional shape.

This invention is not limited to the above-mentioned embodiments; for example, the fitting part 11 of the first gasket 12
The cross-sectional shape of the second gasket 15 and the third gasket 1 can be various shapes such as a tapered groove or a semicircular groove instead of a square groove (or a square convex strip).
8 may also have a cross-sectional shape that fits into this fitting portion 11. Alternatively, the rear side wall portion 8 of the groove 7 of the fireproof panel 2 may have the same dimensions as the front side wall portion 9, and the top surfaces of the side wall portions 8 of adjacent panels may be spaced apart. In this case, it is necessary to insert a joint rod only between the side walls 8, 8 when filling the mortar, but this can be easily done from inside the building.

Furthermore, the panel 1 may be of a type that does not have the semicircular groove 7 on the longitudinal side surface and is attached to the building frame by a method other than the above embodiment.

As explained above, according to this invention, joints with excellent sealing properties against rainwater and mortar can be formed by simply arranging panels vertically and horizontally while fitting the second and third gaskets, and it is possible to form joints with excellent sealability against rainwater and mortar. The insertion/removal work can be omitted or halved,
There is no need to insert a backer, making panel wall construction easier. In particular, if the second and third gaskets have widened parts that contact the side of the panel to improve sealing performance, panel wall construction work can be done from inside the building, and scaffolding on the outside of the wall can be done. Since this is not necessary, the panel wall construction work is further simplified. In addition, the joint intersection is a quaternary second
In addition to being sufficiently sealed by the gasket, the second gasket and the third gasket are abutted against each other on their entire end surfaces, so that a large adhesion area can be obtained, so that a panel wall structure with excellent sealing performance can be obtained.
