Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved panel connector.

When constructing large-span ceilings in large bathrooms and other assembled structures, the most important requirement is the connection strength of the panels. Workability when connecting panels is required.

Technical studies have been carried out from the above viewpoint, but the existing methods cannot satisfy the above-mentioned requirements, and there is still room for improvement.

For example, in the case of the conventional example shown in FIG.
Ribs b and b' are provided protruding from the connecting end of a', and panels are connected by abutting these ribs b and b' against each other and bolting, but in this conventional example, the connection work is simple. The connecting part (rib b,
There is an inconvenience that the strength of the entire panel must be increased more than necessary to ensure the strength of b'), and in addition, it is difficult to process panels a and a' by integrating ribs b and b'. Furthermore, if the panels a and a' become distorted due to aging, an unsightly gap will occur between the ribs b and b'.

For this reason, a means has been adopted for connecting the panels a, a' by means of a panel connecting tool which is processed separately from the panels a, a'.

Figure 2 shows an example of the panel connector c. In the case of this panel connector c having an I-shaped cross section, the connecting ends of panels a and a' are fitted into the recesses on both sides of the panel connector c. At the same time, in the remaining space, there is a square piece d,
d' is compensated for, and the panels a and a', the square members d and d', and the panel connector c are fixed to each other with screws, adhesive, or the like.

When using the panel connector c in Fig. 2, it is possible to ensure sufficient panel connection strength by having an I-shaped cross section with excellent strength and by using the square members d and d' as auxiliary members, and the connector itself Although it can be said that the processing is simple, there is the hassle of having to fit not only the panel connecting ends but also the square pieces d and d' into the recesses of the connector c, and fixing each member one by one. In particular, as the thickness of panels a and a′ changes, the square pieces d and
Since d' must also be prepared in different sizes, square timbers d and d' of various sizes are required.

On the other hand, a panel connector shown in Fig. 3 has been proposed as a panel connector that can omit screws and adhesives, etc. This panel connector c has a flat approximately I-shaped fitting part e and a vertically long approximately C-shape. A reinforcing groove f is formed integrally with the reinforcing groove f, and a reinforcing plate g that can be freely fitted into the reinforcing groove f is combined.

In the panel connector c shown in Fig. 3, the work is completed by simply fitting the connecting ends of panels a and a' into the fitting part e and fitting the reinforcing plate g into the reinforcing groove f. Since the connection state is stable, there is no need for screwing or gluing, so compared to the above-mentioned method, the number of steps is considerably reduced, and there is no need to worry about strength.

However, in the panel connector c in Fig. 3, the inset part e is compatible only with a single size panel with respect to the thickness of panels a and a'. Moreover, since the cross-sectional shape is complicated, it is difficult to process.

Other conventional techniques include Utility Model Application No. 48-98908, Utility Model Application No. 52-127616, Utility Model Application No. 52-148417,
The panel connecting means disclosed in Japanese Patent No. 54-28917 is known.

In these known techniques, protrusions and grooves are formed relative to each other on the plate-like portions of the pair of connecting members,
When such a connecting member is used, the panels are connected by sandwiching the panel connecting ends between these plate-shaped portions in a sandwich-like manner, and at the same time, engaging the protrusions and grooves relative to each other.

At this time, the connecting members are fixed to each other by a projection, a locking shape formed relative to the groove, or a screw.

Among the above-mentioned known examples, those in which a retaining shape is formed in the protrusion or groove are more convenient in that they do not require screws or adhesives, but the panel connection state is not as solid as screws or adhesives. In addition, it is difficult to obtain a high degree of adhesion of the connecting member (particularly the plate-shaped portion) to the panel surface.On the other hand, screw fastening means can ensure a solid panel connection state, but the connecting member It takes time and effort to drill the holes and to prevent the screws from loosening.Other problems common to these known examples include the lack of any means to provide the connecting member with a sufficient reinforcing function.

In view of the above-mentioned problems, the present invention has been developed to satisfy the technical requirements of this type of panel connector in a multifaceted and comprehensive manner.The configuration of the panel connector will be explained below with reference to the illustrated embodiment. do.

In Figures 4 and 5, 1 and 2 are a pair of connecting members molded mainly from synthetic resin such as vinyl chloride or FRP, and both connecting members 1 and 2 are long ones. By cutting it to an appropriate length, it has a predetermined dimension (length).

One of the connecting members 1 in the above is the clamping plate portion 3
and a piercing protrusion 4 protruding from the plate surface of the clamping plate 3, and screw holes 5a and 5b protruding from both sides of the piercing protrusion 4 on the plate surface of the clamping plate 3. It is equipped with

Moreover, in the illustrated case, the concave groove part 7 is formed by protruding to the back surface of the connecting member 2, that is, to the back side of the clamping plate part 6, and the widthwise middle of the clamping plate part 6 also extends in the same direction. It is warped so that it protrudes.

One embodiment of the present invention consists of the above, and when connecting the panels a and a', as shown in FIG. 4 and FIG.
The insertion convex piece 4 is inserted into the recessed groove part 7 with the two facing each other. In this state, after the connecting ends of panels a and a' are clamped by both clamping plates 3 and 6, the through holes 8a and By tightening the screws 10, 10' inserted from 8b across the screw holes 5a, 5b, both the clamping plate parts 3, 6 are attracted to each other,
This fixes the panel clamping state to obtain a predetermined panel connection state.

At this time, the clamping plate part 6 of the connecting member 2, which has been warped as shown in the figure, comes to follow the surfaces of panels a and a', and the biting tooth surface 9 of the clamping plate part 6
A and 9b also partially or completely dig into the panel surface.

When connecting panels a and a′ in the above manner,
The pair of connecting members 1 and 2 are connected to these clamping plate parts 3 and 6.
and the insertion convex piece 4 form two fitting recesses, and the outer surfaces of the screw holes 5a, 5b are in the same position when the panel connecting end is fitted into these fitting recesses. Since it also serves as a fixing stopper, by fitting the panel connecting ends into the respective fitting recesses, the predetermined panel butting state can be achieved accurately, and both the clamping plate parts 3 and 6 also fit into the insertion convex piece 4 and the concave groove part. 7 are relatively fitted, so that the facing state of the two parts 3 and 6 does not collapse involuntarily, and therefore, the operation is simple in that the insertion convex piece 4 and the groove part 7 are relatively fitted. The panel connection work can be performed accurately based on this.

In addition, by tightening the clamping plates 3 and 6 using the inserted convex piece 4 and groove 7 in the fitted state as guides, a large clamping force for the panel connection end can be secured, and further The convex piece 4 and the concave groove part 7 exhibit the rib effect of the triple wall structure, and the combined structure of both the connecting members 1 and 2 has an inverted T-shape cross section with excellent strength, so it is possible to connect panels over a large span. can also withstand this.

Of course, even if the panels a and a' shrink or become distorted over a long period of time, as long as their connecting ends are held by the holding plates 3 and 6, harmful and unsightly gaps will not occur.

Furthermore, the clamping plate portion 3 in both the connecting members 1 and 2,
By adjusting the relative spacing of 6, it is possible to accommodate panels of various thicknesses, so that 1
Versatility and compatibility not limited to different panel thicknesses can be obtained, and since the connecting members 1 and 2 are both inverted T-shaped in cross section and do not have unique or complicated shapes, they are easy to process. .

In addition, the clamping plate portion, which is also provided with screw holes 5a and 5b in addition to the insertion convex piece 4, is hard to bend, and has screw holes 5a, 5b.
As described above, the bent holding plate portion 6 without 5b is easily bent.

Therefore, from the through holes 8a, 8b, the screw hole portions 5a,
When the clamping plate parts 3 and 6 of both connecting members 1 and 2 are tightened with the screws 10 and 10' inserted into the screws 5b, one of the clamping plate parts 3 comes into close contact with the panel surface without being deformed. On the other hand, the other holding plate part 6 deforms from a warped state to a flat state and comes into close contact with the panel surface.

Moreover, at this time, the panel connecting end easily comes into contact with the unwarped clamping plate part 3, and the clamping plate part 6, which has deformed from the warped state to the flat state, prevents the screws 10 and 10' from loosening due to the reaction force. to do.

In addition, in a normal usage mode, the holding plate part 6 having the groove part 7 faces the ceiling.

The outer shape of the screw holes 5a and 5b is a polygon such as a quadrangle.

The biting tooth surfaces 9a, 9b are formed on either or both of the clamping plate parts 3, 6, or
The biting tooth surfaces 9a, 9b of these clamping plate portions 3.6 are omitted.

As explained above, the present invention provides a panel connector for connecting the connecting end of one panel and the connecting end of the other panel by abutting each other. The pair of connecting members each include holding plate portions facing each other, and the inner surface of the holding plate portion of one of the connecting members has a spike rising from the widthwise middle of the inner surface with a dimension larger than the panel thickness. An insertion protrusion piece is provided, and in correspondence with the insertion protrusion piece, the inner surface of the clamping plate portion of the other connecting member is recessed from the middle in the width direction of the inner surface to accommodate the clamping plate part. A concave groove rising toward the outer surface of the plate is provided, and between both ends of the one clamping plate and both sides of the insertion convex piece, the inner surface of the clamping plate is formed with a dimension equal to or less than the panel thickness. A screw hole protruding in the same direction as the insertion convex piece is provided, and corresponding to the screw hole, a screw hole is provided between both ends of the plate and both sides of the groove in the other holding plate. , through holes for screw insertion are provided, and the holding plate portion having these grooves and through holes is characterized in that the middle portion of the inner surface in the width direction is curved in the direction of separating from the panel surface. .
