Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a panel connecting device used for the exterior or interior of a building, and particularly to a panel connecting device that can be installed selectively at joints.

(Prior Art) For example, long and wide exterior panels are used for horizontal cladding, which are continuously stretched on the exterior wall of a building to cover it.

This type of exterior panel is made of, for example, an extruded aluminum alloy material, a cast material, or a molded material of baked painted steel plate.

This exterior panel is generally provided with a wide U-shaped connecting groove that opens to the front side at the L end and a locking line that defines the north edge of the connecting groove, and the lower end is folded toward the back side. The bent bundles are bent and have the same locking strips at the tips, and to connect them, the bent bundles are inserted into the connecting grooves in a close overlapping manner, and each locking strip is connected to the building. It has a structure in which it is fixed to the side and supported by a halter metal fitting interposed between them, and with this structure, the connecting groove and the lower surface of the bent groove inserted therein are connected to each other. It is said that a joint is formed between the two.

[Problem to be solved by the invention] With this connecting device, joints are naturally formed between adjacent exterior panels, and the spacing and position of the joints depend on the vertical width of the exterior panels used. Since the joints are fixedly determined, there is no freedom to install the joints arbitrarily in the design, for example, depending on the exterior appearance of the building.

In particular, 1. For example, when using an exterior panel made of extruded aluminum alloy, if the thickness of the extruded material is set to a practical level of 2 a+m or less, the width of the extruded material is 15 to 20 cm.
Generally, the width is about 30 m, so in this case, joints will be formed for each width, which may give an extremely complicated impression depending on the building. For example, 30 m
Due to the texture of the material, if an extruded aluminum alloy material is used instead of a steel plate molded material that can obtain a width of ~90 cm, the design may be adversely affected.

The present invention was made in view of these problems, and
The purpose is to provide a panel connecting device that can freely select and install joints by breaking the correlation between panel width and joints and relatively freely controlling the spacing, number, and position of joints.

[Means to solve the problem]

The present invention aims to achieve the above-mentioned object, and has a plurality of pairs of equally spaced locking protrusions protruding from the back side of one panel at the overlapping connection end position of the #-contacting panel; Joint selective installation characterized by comprising at least a single locking ridge provided on the front side of the panel, and a joint ridge parallel to the locking ridge on the inside of the locking ridge on the front side of the other panel. A flexible panel connection device (Claim 1), and without requiring the joints of Claim 1, and in place of a plurality of equally spaced pairs of locking ridges and at least a single locking ridge. The present invention relates to a panel connecting device that can be selectively installed at joints, and is characterized by comprising at least a pair of locking protrusions at a predetermined interval and a plurality of pairs of locking ridges at equal intervals corresponding to the spacing. This is the gist of the invention.

[Function] According to claim 1 of the present invention, any one of a plurality of pairs of equally spaced locking protrusions is locked to at least a single welding locking ridge, and the inner side of the latching ridge The joint placement is used to control the connection end such that the joint strips are exposed as needed to serve as a joint or covered to prevent joint formation.

On the contrary, in claim 2, at least a single locking protrusion is locked to one of a plurality of pairs of locking ridges at equal intervals to cover the locking ridge, and the locking rib also serves as an inner joint. The retaining strip is exposed, or other joint strips provided with the retaining strip are exposed, and used to control the ground installation in the same manner as described above.

(Example) The present invention will be further described below with reference to drawings showing examples. In FIGS. 1 to 5 according to claim 1, Ia,
lb...In are exterior panels connected so as to be adjacent to each other, and these exterior panels la, lb...1n are integrally constructed of aluminum alloy extruded material having the same size and shape.

That is, each exterior panel la, Ib...1n is 1
It was made into a long piece having a height and width of 25 mm, and a decorative horizontal ridge 12 was formed on the surface side. At the site-shaped panel base 11 and at each overlapping connection end position of this panel base 11, that is, at the upper end of each exterior panel la, Ib...1n, equally spaced 2 portions 2 protruding from the back side are provided. A pair of locking protrusions 20° 21 and 21.22, and at the lower end, a single locking ridge 3o provided on the front side and a joint ridge 4o on the inside of this ridge, that is, the lower joint ridge 3o. This is assumed to be equipped with the following.

The two pairs of locking protrusions 20, 21 and 21.22
By sharing books, it is composed of three trees with an odd number,
Each of these includes a horizontal strip 23 projecting horizontally and a locking protrusion 24 at the tip thereof.

- On the other hand, in this example, the mooring receiving strip 30 is so arranged as to fit the pair of mooring protrusions 20, 21 and 21, 22, respectively.
It has a groove shape with an opening on the front side corresponding to the spacing between the protrusions 20 and 21.22, and a groove is formed on the inner surface of the opposing strips 32.33, which have the same length on the upper and lower sides and are opposite to each other, and which define the locking ridge 30. teeth,
A facing protrusion 35 that engages with the above-mentioned engagement protrusion 24 is provided.

Further, in this example, the joint line 40 is provided on the inside of the locking groove 30, that is, on the panel base 11 side, parallel to the front side so as to be immediately adjacent to the locking groove 30. It has a groove shape that is slightly shallower than the locking ridge 30. Reference numeral 41 in the figure denotes a dog-shaped piece that connects the facing line 30 and the upper end of the panel base 11 so as to separate the joint line 40 from the lower facing line 33 of the locking receiving line 30.

In the exterior panels la, lb...In thus constructed, as shown in FIGS. 3 to 5, joints can be formed arbitrarily by exposing or covering the joints 40. .

That is, FIG. 3 shows two adjacent exterior panels 1a, lb.
At the overlapping connection end position, the lower pair of locking protrusions 21 and 22 of the two equally spaced pairs on the upper exterior panel la are connected to the locking ridges 30 of the lower exterior panel lb.
This is an example in which a joint is installed between these panels la and lb by engaging them in a fitted manner and exposing the joint strip 40. Furthermore, FIG. 4 shows that among the two pairs of equally spaced pairs, the E-side pair of locking protrusions 20° 21 are similarly locked to the locking ridges 30 to connect these exterior panels la and lb. On the other hand, the joint strip 4o is covered by the lower end of the panel base 11 at the position of these pair of locking protrusions 21 and 22, and these panels la, lb are covered without forming a joint.
This is an example where the two are placed in close contact with each other. In addition, the locking is done by a snap-in method by pressing from the front side, and when the joint line 4o is exposed, the remaining latch 1 protrusion 20 or 22 is received in the space above the latch 30, On the other hand, when this is covered, it is received in the joint line 40,
It is assumed that these remaining IL protrusions 20 do not cause any hindrance during fitting and locking by 22.

5(A) to (C) are examples in which the joint spacing, number, and position are changed depending on the exterior panels la, lb...In of this example, and (A) is each exterior panel la.

(B) is an example of a connection in which joints are installed alternately between two exterior panels Ia and Ib and one exterior panel lc, and (c) is an example of a connection between two exterior panels Ia and Ib and one exterior panel lc. la, lb, I
An example of a connection in which joints are installed every c is shown.

In addition, in Fig. 1 and Fig. 2, work 3 is.

At the side ends of the exterior panels la, lb...1n, the panel base 11 is bent toward the back side in order to avoid exposure of the cut surfaces, and 50 is a longitudinal direction fixed to the building frame 80. 60 is a sealing material at the side edge of the exterior panels la, lb...in, and 70 is the base material provided at a position defining the lower end of the building or a window opening, etc. An end member used in common with the channel material 50 is shown.

On the other hand, FIG. 6 shows an embodiment according to claim 2, in which the lower end of the adjacent panel la has a protrusion on the back side at the overlapping connection end position of the adjacent panels la and lb. A pair of locking protrusions 20, 21 are provided at a predetermined interval, and three opposing strips 32, 33°3 are provided at the upper end of the lower adjacent panel lb.
Consists of 4. Two pairs of groove-shaped locking ridges 30 and 31 are arranged at equal intervals corresponding to the spacing between the locking protrusions 20 and 21, and the rest is the same as the above example except for the horizontal ribs. Since they are the same, they will be given the same reference numerals and their explanation will be omitted.

In this example, the pair of locking protrusions 20 and 21 are fitted and locked to the upper locking ridge 30 to form the exterior panels la, lb...
・By connecting the in, the lower groove-shaped locking ridge 31 is exposed on the front side, and a joint is created by this latching ridge 31. Also, a pair of latches +17-projections 20, 21
By fitting and locking and connecting to the lower power receiving 31, the locked power receiving 31 is covered with the panel base 11 of the upper exterior panel la, and the upper and lower exterior panels la and lb are connected. The joints are brought into direct contact with each other, and the joint spacing and position can be freely controlled as in the previous example.

In the example shown above, if there are multiple pairs of locking protrusions at equal intervals, the number of locking protrusions can be increased compared to the examples shown in FIGS. 1 to 5 above. By configuring every other opposing strip as a pair, the exposed width dimension of the joint strip can be adjusted freely, and two pairs of the increased number of locking protrusions can be used as two arbitrary locking strips. By locking it to the power receiving side, it is possible to install joints freely and improve the strength of the connection.

On the other hand, the locking power reception may be locked on the non-opposing surface of the opposing protrusion so as to be fitted into the locking protrusion,
Further, in this case, the IJx power receiving section is not formed in a groove shape, but is formed in a ridge shape that protrudes toward the front side.

The joint line does not have to be a single one; for example, it may be configured as a plurality of joints facing inward so that multiple joints appear, and when there are multiple fixed power receptions, these It is also possible to provide this joint between or even inside these.

In addition to the above-mentioned exterior panels, the panel connection device of the present invention can be applied to interior wall materials, ceiling materials, and interior and exterior panels constructed by connecting a wide range of panels such as eaves. In addition to upper materials, it can be applied to any material such as steel molded materials, aluminum alloy prefabricated materials, synthetic resin extruded materials, etc. And when using other materials like this,
For example, if it is not possible to mold the locking protrusion and locking power reception integrally as in the case of a cast material, then the locking protrusion or the locking protrusion, such as a separately molded aluminum alloy extruded material, can be used for the cast material panel. The present invention can be widely implemented by applying fixing means such as adhesion or screwing to the fixing substrate for stopping and receiving electricity.

Furthermore, when providing a locking power receiving device that also serves as a joint as shown in Figure 6 of L, it is possible to provide a cutout in the opposing protrusion to facilitate drainage, or to apply the present invention to a part of the outer wall surface or inner wall surface. In carrying out the present invention, including the point that Various modifications may be made and there is no need to be limited to the examples shown or described above.

(Effects of the Invention) The present invention, configured as described above, controls the installation of joints between adjacent panels as shown in claim WIJ paragraph 1 and claim 2 claim 2 action column. Therefore, the correlation between spring convergence and joints can be cut off, and the spacing, number, and position of joints between panels can be determined relatively freely, and joints can be installed appropriately for the exterior and interior of buildings. This enables the panels to be connected to each other and improves the overall appearance of the panel surface.

In addition, since the present invention breaks the relationship between the panel width and the joint, it is not necessary to use panels with many different width dimensions, and it is possible to use only a few width dimensions, and even one type of width. The appearance of the panel surface can be varied depending on the size of the panel.1 For example, when using a panel made of extruded aluminum alloy material, even if the panel width is restricted by the material, it can be used regardless of the panel width. , similar diversification can be done.

In addition, the structure of the connecting device of the present invention is simple, and it is sufficient to lock the locking protrusion and the locking power receiving, so the connection work can be easily done and the joint installation can be controlled easily.
Not only does this happen naturally when the panel is connected, but when replacing it, for example, if the panel is deformed or damaged, it is sufficient to release the lock and re-lock another panel, which can be done extremely easily.
