[0006]

【Example】

The following is a first example in which the present invention is applied to the roof of an aluminum carport. This will be explained with reference to FIGS. 1 to 3. First, in Fig. 3 showing the roofing structure of this example, the left and right sides of the carport are On the top surface of each beam 2, which serves as a long mounting member, is installed at a predetermined interval between girders 1. A locking groove 4 is provided in the longitudinal direction, and the plate material is made of two acrylic resin plates. The plurality of roofing materials 3 are placed on each edge from both sides of the beam 2 in the longitudinal direction. Insert the fitting protrusion 7 of the edge fixture A, which is placed so as to straddle both edges, into the latching groove 4 of the beam 2. By pushing the roofing material 3 into the non-removal state, the edge of the roofing material 3 is fixed to the beam 2 in a watertight manner. There is.

[0007] The beam 2 made by extrusion molding aluminum material has a substantially square cross section as shown in Figure 3. Then, in the center of the width direction of the upper surface 2a, which is the mounting surface for the roofing material 3, a hooking groove 4 is formed. It protrudes integrally in the longitudinal direction. This latching groove 4 has an upward U-shaped cross section. On the inside of each upper end of both legs, engaging claws 4a, 4a facing each other are provided. ing. Further, a long sealing material 5 made of rubber is fitted to both side edges of the upper surface 2a of the beam 2. A fitting groove 2b is integrally provided. In addition, the beam 2A that constitutes the gables at both ends of the roof has a fitting groove 2b only at one edge. It is set up.

[0008] The edge fixture A shown in FIG. A fitting protrusion 7 is integrally provided at the center of the lower surface of the body 6 over its entire length, and a fitting protrusion 7 is provided on both sides of the lower surface. has a structure in which a packing 8 is integrally provided over the entire length. The main body 6 and the fitting protrusion 7 are made of hard synthetic resin with excellent weather resistance, respectively. For example, ASA resin (a copolymer of acrylic rubber, styrene, and acrylonitrile) ) or hard vinyl chloride resin, while packing 8 is made of highly flexible elastic material. materials, such as styrenic thermoplastic elastomers and non-migratory soft vinyl chloride; Alternatively, use non-plastic soft vinyl chloride or the like. The fitting protrusion 7 has an interval that allows the two protrusions 7a, 7a to be inserted into the locking groove 4. The protrusions 7a, 7a each have a hook at the lower end. A pair of engaging claws 7b, 7b that are engaged with a pair of engaging claws 4a, 4a of the service groove 4 face outward. It is set up in

[0009] Figure 2 shows an edge fixture A1 used for the beams 2A at both ends that constitute the gable end of the roof. ing. The difference from the edge fixture A is that the upper surface of the beam 2A has a Since the roofing material 3 is placed only on the main body 6, the packing 8 is also placed only on one side edge of the main body 6. A rib 9 of a predetermined height is provided downwardly on the other side edge of the main body 6.

0010 Next, the action of the edge fixture A will be explained. To cover the roofing material 3 on the beam 2, first, the edges of each of the two roofing materials 3 are It is placed on the upper surface 2a of the beam 2 as shown on the right side of FIG. At this time, the end face of the edge should be Since it is in a positional relationship in which it comes into contact with the outer surface of the mating protrusion 7, it does not cover the latching groove 4. It never happens. Next, the edge fixture A is placed in a state where its fitting protrusion 7 is inserted into the latching groove 4. When the packing 8 is pressed onto the beam 2, the packing 8 is pressed against the edge of the roofing material 3. At the same time, the pair of engaging claws 7b, 7b of the fitting protrusion 7 engage with the engaging groove 4. Lower the pair of hooking claws 4a, 4a to the left and right, and push the edge fixing tool A further. When basting, the engaging claw 7a comes out below the engaging claw 4a, so the pressing force is released at this time. If this occurs, the opposing distance between the engaging claws 4a, 4a, which had been pushed outward, will return to its original state. , each pair of engaging claws 4a, 4a and 7b, 7b are engaged with each other in a manner that they cannot be removed. So Therefore, the edge of the roofing material 3 is compressed with the sealing material 5 attached to the upper surface 2a of the beam 2. It is sandwiched between the gasket 8 and the gasket 8, and is securely fixed to the beam 2 in a watertight state.

[0011] FIG. 4 shows a second embodiment of an edge fixture A2. The difference from the edge fixing tool A of the first embodiment is that the strip-like main body 6 is shaped convexly in the width direction. It is located in a slightly curved area. This increases the rigidity of the main body 6 and makes it resilient against pressing force from above. The deformation recovery property is also increased, and the fixing force of the roofing material 3 by the edge fixing device A2 is increased. Ru. Furthermore, by increasing the wall thickness at both end portions of the main body 6, structural strength can be increased as well. In addition, unevenness is provided on the joint surface between the main body 6 and the packing 8 to increase the joining force between the two. ing.

0012 5 to 7 show a third embodiment of the edge fixture A3. The first difference from the edge fixing tool A is that the fitting protrusion 7 has two pronged ends. As shown in FIG. 5, they are connected to each other by a thin connecting portion 7c. This series The connection point is not limited to the ends of both ends as shown in Figure 7, but is also connected in a way that does not interfere with the bottom of the engagement groove 4. Alternatively, it may be near the tip of the fitting protrusion 7. When the main body 6 is made of a material with a certain degree of flexibility, the connecting portion 7c is connected to the main body 6. Use the same material, but if it is less flexible, use another material with more flexibility to mate. It is co-extruded with the protrusion 7. Alternatively, connect only the both ends of the edge fixing tool A3 of the standard length. The connecting portion 7c may be attached later. The second difference is that the cross-sectional shape of the packing 8A is formed into a solid downward concave shape. It's there. The effect of this embodiment is as shown in Fig. 6 when the material of the roofing material 3 deteriorates over time and is replaced. As shown, for example, a tool is inserted into the inner cavity of the fitting protrusion 7 from the end surface of the edge fixture A3. Insert the tip of a screwdriver 10 or the like and push down the connecting part 7c, Since both engaging claws 7ab and 7b approach each other, the engaging protrusion 7, which was in the prevented state, is engaged. It can be easily pulled out from the groove 4. So, pull this detached end. For example, the edge fixture A3 can be removed easily and quickly.

[0013] In addition, in each of the above embodiments, the latching groove 4 provided in the beam 2 and the latching groove 4 are Of course, the purpose of the present invention can be achieved even if the shape of the fitting protrusion 7 to be fitted is changed as appropriate. will be accomplished. In addition to the beams in the above embodiment, the long mounting members can also be used for frame members of various structures. Of course, the plate material is not limited to an acrylic resin plate.

[0014]

[Effect of the idea]

As is clear from the above explanation, the plate edge fixing device according to the present invention is as follows. It has excellent practical effects as listed above. (a) For example, when roofing aluminum carports, terraces, etc., conventional press If you use the edge fixing device of this invention instead of the presser foot edge, you can remove the bolt from the presser foot edge, which was previously done. Drill the bolt hole, paste the string-like packing, and install nuts at multiple locations on the beam. This eliminates the need for extremely time-consuming and time-consuming preparation work. Instead, the fitting protrusion of the edge fixture is pushed into the latching groove of the elongated mounting member. One-touch installation is now sufficient. (b) And, as in the past, a large number of bolts and nuts fix the presser foot to the beam. It also eliminates the need for string-like packing for water-tight sealing, so there is no need to purchase and store these auxiliary materials. It eliminates the need for time and expense. (c) Therefore, compared to the conventional clamping method using bolts and nuts, In addition to significantly improving work efficiency, the cost of auxiliary materials is eliminated, making it easier to install plate materials. This can significantly reduce the amount of work time and costs required. (d) Furthermore, tighten the aluminum presser foot and the beam with ferrous metal bolts and nuts. It also eliminates the electrochemical corrosion problem of conventional aluminum materials caused by bonding.
