DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure of an outer wall panel constituting an outer wall of a building, and more particularly to a joint structure having a waterproof sealing function.

[0002]

2. Description of the Related Art Conventionally, as an outer wall of a building, there is a structure in which a concrete panel having a predetermined size or a lightweight cellular concrete panel is attached to a steel frame adjacently to form a panel wall. In this case, as a method of sealing joints between adjacent outer wall panels, it is common to assemble the panel walls at a building site and then fill the joints of the outer wall panels with a flowable amorphous sealing material. However, in the case of processing by this method, it is necessary to provide a scaffold for construction outside of the outer wall. Also, depending on the skill of the operator, sufficient performance as a joint seal cannot be obtained, and the sealing effect tends to deteriorate due to aging.

Further, as shown in Japanese Patent Application Laid-Open No. 63-63843, a soft sealing material is fixed to only one joint surface of the facing outer wall panel in advance over its entire length.
At the time of assembly, there is also a method of applying a flowable sealing material or an adhesive to the joint surface of the other outer wall panel and bonding them, but there is the same problem as described above because it is limited to on-site construction. On the other hand, as shown in Japanese Patent Application Laid-Open No. 2-289736, there is also a method in which gaskets having irregularities that can be fitted are fixed to both joint surfaces of opposed outer wall panels, and both are fitted together during assembly. However, if the position of the facing outer wall panel shifts during construction, there is a problem that the fitting becomes insufficient and the sealing effect is reduced.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and eliminates the necessity of installing a scaffold when assembling a panel wall at a building site. An object of the present invention is to provide a joint structure of an outer wall panel in which a seal can be obtained.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a first sealing member which is fixed over the entire length of one of the opposed joining surfaces of an outer wall panel which is achieved adjacently. An outer wall panel having a second seal member fixed to the other joint surface over the entire length of a position where the second seal member can contact the first seal member, and both of which are pressed against each other to form a waterproof seal. In the joining structure of (1), the first seal member is formed of an elastic body and has a protrusion having an arc-shaped cross section at one end and at least one protrusion protruding in the same direction as the protrusion at the other end. The second seal member is made of an elastic body like the first seal member, and is easily elastically deformed by the pressing of the ridge to receive the ridge in a tight fit. The joint structure of the outer wall panel, which has a seat, is provided here. It is intended to.

[0006]

According to the present invention, when the adjacent wall panels are joined to each other on site, the arc-shaped ridge of the first seal member is strongly pressed against the seat of the second seal member. As will be apparent from the later-described embodiment, the seat is formed of a hollow groove-shaped member as the second seal member or is formed of a softer elastic material than the first seal member 20 including the ridge in order to facilitate elastic deformation. As a result, the seat is easily elastically deformed into a shape surrounding the ridge, and as a result, the ridge and the seat form a tight fitting structure. Since the restoring elasticity of the seat works in the direction of urging the close fitting force between the first seal member and the second seal member on the opposite side of the same outer wall panel, the outer wall panels are firmly joined in the coupling direction. Place. The fins of the first seal member serve as primary windbreaks and waterproofs for one opening (front opening) of the joint joint space, and the first and second seal members located inside the first sealing member are closely fitted to each other. It acts as a secondary windbreak and waterproof. As can be seen from the above joining procedure, in the present invention, joining is achieved by a continuous operation of simply pushing one outer wall panel into the mating panel in the coupling direction, so that joining work is extremely simple. In addition, there is an advantage that it is not necessary to adopt a wide foothold for workers as in the prior art.

Embodiments of the present invention will be described below. FIG. 1 is a partial longitudinal sectional side view of a joint state when the joint structure of the present invention is applied to a case where outer wall panels are vertically coupled (FIG. 3).
FIG. 2 is a view similar to FIG. 1 but before joining, FIG. 3 is a partially cutaway side view showing a coupled state of the outer wall panel, and FIG. FIG. 5 is a side view of another embodiment of the seal member, FIG. 5 is a side view showing another embodiment of the second seal member, and FIG. 6 is a case where the joint structure of the present invention is applied to the case where the outer wall panel is coupled in the left-right direction. FIG. 4 is a partial cross-sectional plan view of the joined state of FIG. FIG.
1 and 2, which are longitudinal sectional views taken along line AA of FIG. 1, a first seal member 20 is attached to one of the opposing side surfaces 11 of the outer wall panel 10 assembled vertically adjacently over its entire length. Have been. As shown in FIG. 2, the first seal member 20 has a protrusion 21 having an arcuate cross section at one end, and one fin 22 in the same direction as the protrusion 21 at the other end. Fitting 23 projecting from the back surface of the projection 21
1 is provided along the entire length of the side surface 11 of the panel.
2 and fixed. As shown in FIG. 2, the height H1 of the ridge 21 is equal to or less than the interval between the panels after assembly, that is, １ ／ the width of the joint 40, and the height H2 of the fin 22 is slightly larger than the width of the joint 40. It is large and does not protrude outward from the outer surface of the panel. Fins 22
May be provided as required, as in the embodiment of FIG. 4, or more than two may be provided.

The other opposite side surface 13 of the outer wall panel 10
, A second seal member 30 is fixed over the entire length. The second seal member 30 is a channel material having a quarter-arc shape in cross section, is made of an elastic body softer than the first seal member 20, and has a seat 32 facing the ridge 21. A fitting strip 31 projecting from the back side of the seat 32 is fitted and fixed in a groove 14 provided over the entire length of the side surface 13 of the panel. The height H3 is slightly larger than the width of the joint 40, and the width D3 is larger than the width D2 of the ridge 21.

The second seal member 30 may be a hollow body having a trapezoidal cross section as shown in another embodiment of FIG. 5, or a hollow body having a right-angled triangle (not shown). This is because the material of the sealing member 30 in the embodiment of FIG. 5 is the same as that of the first sealing material. Therefore, when the receiving seat 32 is made of a hollow groove, it is easily elastically deformed when pressed by the ridge 21. The ridge 21 is easily received in a tight fit. As in the previous example, the material of the second seal member 30 may be an elastic body softer than the first seal member.

FIG. 6 is a partial cross-sectional view taken along the line BB of FIG.
FIG. 4 shows a cross section of a joint portion when the outer wall panel is joined in the left-right direction. Notch surfaces 15 and 16 are formed on the front sides of both opposed side surfaces 11 and 13 over the entire length of the side surface. Grooves 1 are provided in the backs connected to the cutout surfaces 15 and 16.
2 and 14 are formed, the groove 12 has a fitting 23 of the first seal member 20, and the groove 14 has a second seal member 3.
Zero fittings 31 are fitted and fixed respectively.

It is desirable that the seal members 20, 30 have elasticity and are excellent in weather resistance and heat resistance, and silicone rubber, silicone sponge and the like can be used.

A method of assembling the panel according to the embodiment will be described below. Before assembling, the first sealing member 20 is fixed to the joint surface 11 corresponding to the side surface and the bottom surface of the one panel 10 and the notch 15, and the joint surface 13 corresponding to the side surface and the upper surface of the outer wall panel facing each other. The second seal member 3 is fixed to the notch 16, and if necessary,
An adhesive is applied to the surface of 30. Thereafter, one of the outer wall panels is vertically fixed to a steel frame (not shown), and then the opposing outer wall panel is transferred to a position adjacent to the fixed outer wall panel to assemble the panel wall.
After the first seal member 20 and the second seal member 30 fixed to both outer wall panels 10 are brought into contact with each other and adjusted so that a predetermined joint width is set between the opposing outer wall panels. Then, the opposing panels are fixed in close contact. By repeating this operation, a desired panel wall can be assembled.

In this case, since both sealing members 20 and 30 are made of an elastic material, it is only necessary to bring the opposing panels into contact with each other to assemble the panel wall. There is no need to go construction. Therefore, it is not necessary to construct a scaffold when assembling the panel wall at the construction site, and a good sealing result without fitting misalignment or defective filling of the sealing material can be obtained irrespective of the weather or the skill of the operator. In addition, if a painted panel or a panel with a metal or tile attached to its surface is used, it is not necessary to finish the panel wall.

[0014]

As described in detail above, the present invention presses the first seal member and the second seal member made of an elastic body which are fixed in advance over the entire length of the opposing joint surface of the adjacent outer wall panel. The panel wall can be easily assembled on the construction site because it is configured to be closely fitted. Also,
Since both seal members are in elastic contact with each other, it is possible to cope with changes in joint width due to expansion and contraction of the outer wall panel, vibration, etc.In addition, primary waterproofing and windproof action by fins and tightness of both seal members Since a good sealing effect can be obtained due to the secondary waterproofing and windproofing action by the fitting structure, there is a great contribution to the industry.
