Description

[Detailed Description of the Invention] The present invention relates to a combination member of a construction board and a connecting fixture, which is convenient for attaching a plurality of construction boards in parallel to the inside or outside of a building.

Long architectural boards made of inorganic or organic materials are
Recently, it has been used in large quantities because of its advantages such as productivity, design, and construction workability.

However, improvements have been desired in terms of workability, ie, the ease of construction and the robustness of installation when they are installed in parallel on the inside and outside of building construction members.

Specifically, the conventional method for mounting a large number of boards in parallel is to make the side edges of the building boards a real structure and nail them to the construction member at the protruding part, and to connect the parts that cover the protrusion and the construction member. A method of fixing the metal fitting to a construction member by fitting a fastener consisting of a part fixed to the projecting part over the entire longitudinal direction of the protrusion or partially, a method of fixing the metal fitting by hammering the construction board into place, and a method of fixing the metal fitting to a construction member. Various methods have been used, such as a method in which a letter-shaped fastener on the surface is fixed to a construction member in advance, and the side ends of a construction board with a rectangular cross section are inserted into grooves on both sides of the fastener. In the case of real structures, the thin parts are easily damaged by nailing, the fasteners are difficult to fit uniformly with the thin parts, and the fasteners tend to get in the way of fitting the real structure; If the surface of the building board is damaged, there is a risk of water leakage and the appearance and aesthetics are impaired.When using square-shaped fasteners, it is difficult to securely fix them unless they are fixed to the construction member in advance. Therefore, this has actually caused problems such as poor fitting workability of building boards.

The present inventors investigated a method for fixing architectural boards to solve these drawbacks, and found that they formed concave grooves with a special structure on the side edge end surfaces of the parallel architectural boards, and fixed the construction boards in parallel. The planks are butted together via a connecting fixture that partially fits into the groove of the special structure, and the connecting fixture is nailed to the construction member of the building at its center. We were able to achieve the objectives of the term.

Next, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows construction boards 1a and 1b placed on a construction member of a building through a connection fixture 2, and the connection fixture 2 is fixed to the construction member K with a nail 12. This is a cross-sectional view when the groove portion formed in the upper part of the groove is filled with a suitable joint enclosing material 13.

The right side of the figure shows a cross section of the right end of the construction board 1a before the connecting fixture 2 is assembled.

The abutting side edges of the building boards 1a and 1b have grooves that expand toward the end surfaces of the side edges, and the grooves have upper lip-like portions 6a and 6b, slopes 4a and 4, respectively.
The lower lip-like portions 5a and 5b and the small groove 7a each have a
and 7b.

The upper lip portions 6a and 6b may have the same length as the lower lip portions 5a and 5b, but they tend to get in the way when driving the nail 12, and it is difficult to work when filling the joint ring material 13. It is preferable to keep it short.

Furthermore, the inner surfaces 3 of the upper lip-like portions 6a and 6b may or may not be inclined.

The inner surfaces of the lower lip-shaped portions 5a and 5b have an inclination.

This is because when the connecting fixing tool 2 is fixed with the nails 12, the rigid plate 9 curves downward in a convex manner, and the repulsive force of the rigid plate 9 causes the construction boards 1a and 1b to be strongly pressed in the direction toward the construction member. This is to allow a space to be formed between the rigid plate 9 and the lower lip-shaped portion.

A small groove 7 in which a waterproofing agent or waterproofing material 8 is arranged is provided at the inner bottom of the groove formed by the upper lip 6a (6b) and the lower lip 5a (5b).

The waterproofing agent refers to a paste-like material that has adhesiveness and affinity for the construction boards 1a and lb and the connecting fixture 2, and is waterproof and moisture-proof, and is a commercially available caulking agent. I can do it.

The waterproof material corresponds to a flexible rubber sheet or string, a synthetic resin foam sheet, string, or the like.

The small grooves 7a and 7b are provided at positions where they fit into the curved portions 10a and 10b of the rigid plate 9 of the connecting fixture 2 (in this embodiment, the inner portions on the slopes 4a and 4b), so that the construction board 1a and 1b fixation becomes more complete.

The waterproofing agent or waterproofing material 8 is attached to the curved portion 10 of the connecting fixture 2
By pressing a and 10b against the construction member side, the inner wall surfaces of the small grooves 7a and 7b are more completely prevented from spreading (wetting).

The connecting fixing tool 2 has the small grooves 7a on both side edges of a long rigid board 9 having a width that determines the joint between the construction boards 1a and 1b.
and 7b, and two parallel rigid plates 11 a and 11 b are vertically fixed to the widthwise center of the rigid plate 9. .

The distance between the rigid plates 11a and 11b must be at least medium enough to allow an iron nail to pass through when a nail is driven into the construction member K from the upper surface of the rigid plate 9. 5b and the small groove 7a (7b) and the tip curved portion 1.
0 a (10b) It must be of a width that does not interfere with the fitting.

Ultimately, the lengths of the middle and lower lip portions 5a (5b) must be selected to meet these requirements.

In addition, the heights of the rigid plates 11a and 11b must be selected so that the repulsive force of the rigid plate 9 moves effectively.In addition to ordinary nails, screw nails are used for the nails. The distance is determined by the weight of the architectural boards 1a and 1b used,
The law shall be regulated as appropriate depending on the place of use, etc.

The cross-sectional view shown on the right side of FIG. 1 shows a state in which a waterproofing agent (moisture-proofing material) 8 is loaded into the construction board before the connecting fixing tool 2 is assembled.

FIG. 2 is a cross-sectional view of the connecting fixture 2 shown in FIG. 1.

FIG. 3 shows the connecting fixture 2 also shown in FIG. 1.
FIG. 2 is a perspective view of a constant length product.
