Description

[Detailed description of the invention] This invention is applicable to cases in which building boards made by extrusion or bending, such as building wall boards or ceiling boards, are connected with their ends adjacent to each other. The present invention relates to a plate connecting device used for.

Conventionally, in order to make the joints of connected plates water-tight and airtight, caulking is applied to the joints. Therefore, firstly, the caulking work is troublesome, and secondly, the watertightness decreases due to the deterioration of the weather resistance of the caulking material, especially in the case of exterior materials.
Problems such as rain leakage or freezing of infiltrated water occur, and thirdly, the appearance of the connecting portion is damaged.

In view of the above-mentioned points, this idea has been developed to provide a simple structure for the board by attaching an airtight material to the rail material fixed to the base material of the wall or ceiling and providing an abutment edge at the end of the board. It is an object of the present invention to provide a connecting device for plate materials that provides high water and airtightness at the connecting portion of the connecting portion and has an excellent appearance.

In order to achieve the above object, this invention attaches an airtight material to the rail material fixed to the base material of the wall or ceiling, and also provides an abutment edge at the end of the connected boards, and The abutment edge portion is pressed against and held by the airtight material of the rail material to block air flow between the end portions of the connected plate materials and the rail material.

Next, an embodiment of this invention will be described based on the drawings.

In the first embodiment shown in FIGS. 1 and 2,
Rail material attaching means ₂ , which is another component of the base material, is attached to an arbitrary position spaced apart in the longitudinal direction of the through member 1, which is one component of the base material A1. The rail material attachment means 2 consists of a fixing piece 3a such as an inverted L-shape and an adjusting piece 3b such as an L-shape stacked vertically, and a bolt 4 passing through a perfect circle of the fixing piece and a long hole of the adjusting piece. After installing the washer 5, tighten the nut 6 to tighten the adjustment piece 3.
b It is fixed so that the installation height can be adjusted through the elongated hole 10, and a bolt 8 that penetrates the clamping member 7 is passed through the horizontal part of the adjustment piece 3b, and a nut 9 is screwed into the end of the bolt. It looks like it's coming together.

Then, the horizontal part of the adjustment piece 3b and the clamping member 7
The clamping member 7 and the bolt 8 are appropriately spaced apart from each other.
At the same time, a pair of projecting edges ₁₂ and 13 forming an opening of the insertion groove 11 are interposed between the clamping member 7 and the horizontal part of the adjustment piece 3b. After the rail material is positioned at a desired position in the longitudinal direction, the nut 9 is tightened to fix the rail material _B1 to the base material _A1 .

The rail material B ₁ has a joint part 14 forming the insertion groove 11 on the surface of the central part in the width direction, and two grooves 15, 16, 17 each opening in the front direction on both sides of the joint part. A groove 18 is formed over the entire length of the rail material, and airtight members 19 and 20 protruding outward from the opening are attached to the grooves 15 and 17 on the side closer to the joint part 14. Furthermore, airtight members 21 and 22 are installed in the grooves 16 and 18 on the side far from the joint portion 14, and are drawn inward from the opening surfaces thereof. Both airtight materials have appropriate elasticity.

C ₁₁ and C ₁₂ are the rail materials according to this invention.
It is a plate material that is fixed to the base material A ₁ via B ₁ ,
It is used as a finishing material for interior walls, exterior walls, ceilings, etc. of buildings. And each plate material
In C ₁₁ and C ₁₂ , the ends of the adjacent plates are bent to the back side, and contact edges 23a and 24a formed by folding back into an L shape are formed at the ends of the bent parts. has been done.

Among the adjacently connected plates C ₁₁ and C ₁₂ , C ₁₁ is
The abutting edge 23a of one of the plates is connected to the rail material.
Corresponding to the pair of airtight members 19 and 21 on one side of _B1 ,
For example, by tightening the clamp mechanism D ₁ , which consists of a fastener 25 attached to the rail material B 1 and a tightening bolt 26 screwed into the rail material B ₁ from the side opposite to the plate material C ₁₁ of this fastener, the _contact is made. It is attached with the edge 23a pressed against the airtight members 19 and 21. Other plate materials C ₁₂ have the same structure 27, 2
mounted using a clamping mechanism D ₂ with 8;
The contact edge 24a is pressed against the pair of airtight members 20 and 22.

In this way, the space between the end of the board C ₁₁ and the joint 14 of the rail material B ₁ , and the space between the joint and the end of the board C ₁₂ are sealed by the airtight materials 19 and 20, respectively, and the spaces between the end of the board C 11 and the joint 14 of the rail material B 1 are sealed by the airtight materials 19 and 20, respectively. Air flow between the rail materials is blocked.

Furthermore, due to age-related deterioration or vibration of the airtight materials 19, 20, minute gaps may be created between the abutting edges 23a, 24a and the airtight materials 19, 20, or moisture may be contained due to capillary action. Even if air or moisture enters, the airtight materials 21, 22 can be retracted from the opening surfaces of the grooves 16, 18, forming gaps 29, 30 between the airtight materials 21, 22 and the contact edges 23a, 24a. Therefore, this gap prevents any minute amount of air or moisture that may have entered the rail from further entering the inside through the space between the plate material and the rail material due to capillary action.

Note that the airtight materials 19, 20 and the contact edges 23a, 2
If water is allowed to enter the gaps 29 and 30 from between the rails and the rails, there is a risk that the accumulated water will freeze in the winter, causing a loss of water and airtightness between the board and the rail material. .

To prevent this, the abutting edges 23a, 24a
, the gaps 29 and 30 are connected to the spaces 31 and 32 on the back side of the plate material.
It is advisable to provide a hole that communicates with the In this way, the pressurized air that has entered the gaps 29, 30 escapes to the space on the back side of the plate, so the airtight materials 19, 20 regain high adhesion again, and the moisture that has entered evaporates into the space on the back side of the plate. It disappears and never freezes.

The appearance is also good because there is no caulking or airtight material exposed to the outside between the adjacent ends of the two frozen plates C ₁₁ and C ₁₂ , unlike in the past.

In the above embodiment, the fasteners 25 and 27 of the clamp mechanisms D ₁ and D ₂ are straddled over the rail material B ₁ and the plate material C ₁₁ and between the rail material and the plate material C ₁₂ , respectively, and the fasteners are directed toward the rail material. The rail material and the plate material are held together by screwing in the bolts 26 and 28, but the object to which the bolt is pressed in order to tighten the bolt differs depending on the structure of the base material.

For example, in the example shown in FIG. 3, a saddle-shaped rail attachment means 2A is placed astride the through member 1A having an M-shaped or C-shaped cross section, and the locking portion 33 of the attachment means is inserted into the insertion groove 11 of the rail material _B1 . Fit and insert the rail material to attach the rail material, and make the fasteners 25A and 27A sit on the through material 1A on both sides of the rail material B ₁ , respectively, and

3a, 24a, screw the tightening bolts 26, 28 into the upper parts 25u, 26u, and press the tips of the bolts against the threading member 1A.
a, 24a are pressed against the airtight members 19, 21, 20, 22.

In addition, in the example shown in FIG. 4, as an example of application to the connection of ceiling panels, a field edge 35 having an approximately inverted T-shaped cross section is secured to a hanger member 34 suspended from a through member, and is used as a ceiling panel. Contact edges 23 of plate materials C ₃₁ and C ₃₂
a, 24a and both sides of the rail material B ₁ are overlapped with each other, hold them with the lower parts 25l, 27l of the fasteners 25B, 27B, and screw the tightening bolts 26, 28 from the upper parts 25u, 27u of the fasteners, By pressing against the horizontal part of the field edge 35, the contact edges 23a, 24a and the rail material B ₁
is clamped between the lower part of the fastening fitting and the field edge 35, and the abutting edges 23a, 24a are secured to the airtight materials 19, 2.
1, 20, and 22 are pressed against each other.
