Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drainage structure for wallboards, and more particularly to a drainage structure between end faces of long wallboards of a continuous joint structure.

Cement-based materials have traditionally been used as wall materials for buildings.

Among them, the cement-based (mainly made of cement, asbestos, and lightweight aggregate) wall panels that are made by hollow extrusion molding are:
Not only does it have fire retardant properties and durability due to its non-combustibility, and high heat and sound insulation properties due to the air layer in the hollow part, but it also has excellent features such as a heavy appearance and excellent water resistance. It has recently attracted attention as a building material.

Such a cement wall board 1 usually has a male part 2 and a female part 3 along both sides in the longitudinal direction (Fig. 1), and the intermediate part between the two parts 2 and 3 has the above-mentioned part. Multiple through holes 4 for specific purposes
is expressed in an extruded form.

When attaching the wall plate 1 to the building frame structure,
The male part 2 of the wall board 1 is fitted into the female part 3 of the adjacent wall board 1 via the caulking material 5 between the longitudinal side surfaces of the wall boards arranged in parallel on a structure (not shown), and screws, nails, etc. Since it is fixed to the structure using a mounting bracket or the like, it is well protected against rain and secure positioning of both side surfaces (male and female parts) of the wall board is achieved.

That is, the combination of the wall panels in the width direction is rational and perfect.

On the other hand, problems remain with the longitudinal assembly of the wall panels.

Since the long wall boards are cut to fit the size of the building at the site, the finishing accuracy of the cut ends is poor and it is difficult to make joints between the end faces.

In particular, depending on the construction, there may not be a backing material on the back side of the joint, so the gap between the butt end faces of the wall boards to be joined in the longitudinal direction, that is, the joint width, is uneven, and it is difficult to position the end faces. .

Further, due to the above-mentioned problems, there were other drawbacks such as incomplete rain control.

The term "longitudinal joint of wall plates" as used in the present invention refers to the joint between the end faces of two opposing wall plates as shown in Figure 2. It shall be limited to vertical tensions attached to structures.

The present invention was developed in consideration of the above-mentioned drawbacks, and the end surfaces of long wall boards joined in the longitudinal direction are joined by a draining member,
a vertical board having elastic hooks bent and extending from both side edges of the draining member; a joint plate extending horizontally from the board surface over approximately the width of the board; It consists of a draining board that hangs down from the front edge of the joint plate and has a width dimension approximately equal to the width of the board, and a draining board that hangs down from the front edge of the joint board and has a width dimension that is approximately equal to the width of the board, and a draining board that extends between the female and male parts of adjacent wall boards in the width direction and/or the male and female parts. The above-mentioned hooking part is elastically latched onto the part, the above-mentioned joint board is interposed between the end faces of the wall boards adjacent to each other in the longitudinal direction, and the front surface of the wall board below the joint board is connected to the above-mentioned hanging drainer. This provides a drainage structure for vertical wall boards covered with boards.

Hereinafter, the present invention will be described in detail with reference to embodiments.

In FIGS. 3a to 7 showing the first embodiment, parts common to those in FIG. 1 are designated by the same reference numerals.

In FIG. 3a, the draining member has a vertical base plate 11 with elastic hooks 12a and 12b bent and extended from both sides thereof, and in this embodiment, the lower edge of the base plate (another embodiment of FIG. 3b). For example, a joint plate 13 extends horizontally from the middle part of the lower edge and the upper edge) to approximately the width of the board, and a joint plate 13 bends downward from the front edge of this joint plate and extends approximately the width of the board. It is formed by a drain plate 14 having a width dimension equal to .

The latching part 12a is attached to the female part 3 of the upper wall plate 1 to be joined in the longitudinal direction, and the latching part 12b is attached to the adjacent wall plate 1 in the width direction.
It is shaped so as to be elastically hooked onto the female part 3 (indicated by diagonal lines).

It is convenient to shape the widths of the joint plate 13 and draining plate 14 so that they span the outdoor joint line of the wall panels 1 to be joined in the longitudinal direction, as shown in FIG. 3a.

During construction, both latching parts 12a and 12 of the board 11
b is elastically hooked onto the female part 3 between the male and female parts of adjacent wall boards to lock the draining member to the wall board.

When both end surfaces of the wall boards to be joined in the longitudinal direction are brought into contact with each other via the joint plate 13, the upper front surface of the wall board 1 below the joint plate 13 is covered with the draining board 14.

In the embodiment shown in Fig. 3a, the latching is done on the female part 3 of the adjacent wall plate 1, but as shown in Fig. 3b, the elastic latching part 12b is lengthened and fitted. If a structure is adopted in which the male part 2 is also latched at the same time, the fixation to the wall surface will be even better.

In addition to this, the engagement with the male fruit part can be similarly achieved by an extension of 12a.

In FIGS. 6 and 7 showing another embodiment, the draining member is formed by integrally forming two substrates 21, 22, a joint plate 23 and a draining plate 24 located in the middle thereof.

Also, the latching parts (24a, 25a) and (24b,
25b) are each hung on the male part of the wall board.

The embodiments shown in Figures 5b, 6 and 7 have better jointability than the first embodiment (Figure 5a) because they are latched onto both ends of the upper and lower wall plates at the joint. There is.

Since the present invention is constructed as described above, the positional accuracy of the end faces of the wall plates is improved and the strength of the joints is improved.

In addition, the width of the draining part is as short as the width of one wallboard, so the distance for drainage is short, making it easier to drain rain.You can also use short wallboards made from half-finished items without having to discard them, which saves on wall materials. Since it is suspended on the real part of the plate, it has many advantages such as stable joint performance even when used in places where there is no backing material such as a rim on the back of the joint.
