BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture useful for practically attaching a hard wall material having engagement grooves formed on both longitudinal sides thereof.

0002

[Prior Art] In general, a mounting tool for practically attaching a hard wall material having engagement grooves formed on both sides in the longitudinal direction is as follows.
For example, as disclosed in Japanese Utility Model Application Publication No. 63-23427, it has been common practice to process a steel material into a T-shaped cross section, combine it with a Z-shaped angle, and attach a hard wall material to the wall base.

0003

[Problems to be Solved by the Invention] However, if the mounting edge of a fixture made from a structural material is directly inserted into the engagement groove of a hard wall material, the hard wall material is often damaged, and the work is difficult. This required skill and caused problems in construction. In addition, the adhesion between the engagement groove of the hard wall material and the mounting edge of the fixture was poor, resulting in poor waterproofness and airtightness, and the hard wall material was sometimes loose.

0004

[Means for Solving the Problems] In order to solve such problems, the present invention employs a mounting tool to provide a cross-sectional transverse T from the upper and lower mounting edges that serve as actual objects, and the fixed edge protruding from approximately the center of the mounting edges. The fixing edge is fixed to an L-shaped angle attached to the wall base via bolts, and the mounting edge is covered with elastic packing material and inserted into the engagement groove of the hard wall material. This allows hard wall materials to be installed without wobbling or damage, and with improved sealing performance.The packing material that covers the upper mounting edge is made of hard material, and the packing material that covers the lower mounting edge is made of a soft material. As a result, the packing material on the upper mounting edge is hard, so it can withstand the weight of the hard wall material and maintains sealing without breaking, while the packing material on the lower mounting edge is soft, so there is a slight gap between it and the engagement groove. The present invention proposes a fixture for hard wall materials that can follow the formation of voids and maintain its sealing performance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a fixture for hard wall materials according to the present invention will be described in detail below with reference to the drawings. FIGS. 1 and 2 are perspective views illustrating the above-mentioned fixture. A is the fixture, which is formed by processing steel material or extruding metal such as aluminum. That is, the fixture A is formed into a transverse T-shape in cross section by a vertically extending mounting edge 1 and a fixed edge 4 projecting at right angles from approximately the center of the mounting edge 1. The fixture A shown in FIG. 1 is made by spot-welding two L-shaped steel members together to form a horizontal T-shape.

[0006] The upper and lower mounting edges 2 and 3 of the mounting edge 1 are connected to the engagement groove C2 of the hard wall material C via a packing material B to be described later.
, C3 to perform the function of being inserted and connected. Furthermore, holes 5 are formed in the fixed edge 4 at a pitch P1, and this fixed edge 4 is a portion that is fixed to an angle D, which will be described later, with bolts β through the holes 5. Note that the hole 5 is preferably a long hole as shown in FIG. This makes it possible to effectively adjust the level formed by the hard wall material C and adjust the unevenness of the wall base α, which will be described later.

[0007] The packing material B has a substantially U-shaped cross section and has a fitting groove 6 inside, as in the upper packing material B1 shown in FIG. 2(a) and the lower packing material B2 shown in FIG. 2(b), for example. The material may be a plastic body such as polypropylene, polyvinyl chloride, polystyrene, polyethylene, polyurethane, Bakelite, silicone, or EPDM. The upper packing material B1 covers the upper mounting edge 2, and the lower packing material B2 covers the lower mounting edge 3, and mainly covers the sealing material, waterproofing material, cushioning material, and hard material at the connection part of the hard wall material C, which will be described later. It functions as a rattling prevention material for the wall material C.

Furthermore, the packing material preferably has unevenness 7 on its surface, and even if rainwater or the like enters the joints of the hard wall material C, the packing material prevents capillary action and is further improved. The purpose is to improve waterproofness. Further, the upper packing material B1 is made of a hard material, and the lower packing material B2 is made of a soft material.
Since it is hard, it can withstand the weight of the hard wall material C and maintains its sealing performance without breaking, and since the lower packing material B2 is soft, there is some gap between it and the engagement groove C2 of the hard wall material C. The airtightness is maintained without any loss of sealing performance.
It maintains waterproofness and prevents the hard wall material C from wobbling.

FIG. 3 is an explanatory view showing an example of a hard wall material C having a solid structure connected using the fixture A according to the present invention, in which a decorative surface C1 and a substantially concave cross-sectional shape are formed on both sides in the longitudinal direction. In this embodiment, engagement grooves C2 and C3 are formed. Hard wall materials C include cement boards, calcium carbonate boards, calcium silicate boards, ceramic boards, wood chip cement boards, magnesium carbonate boards, etc., or these include glass fibers, whiskers, aramid fibers, steel fibers, carbon fibers, and various mineral fibers. , products mixed with various aggregates, etc. formed by extrusion molding, press molding, injection molding, papermaking methods, etc., or products made by weaving various fibers in a cross shape or three-dimensional shape and impregnating it with cement, clay, etc. It is formed into a panel shape, steam-cured and fired, or it is made of a sandwich panel made by laminating thin metal plates and synthetic resin foam. The hard wall material C shown in FIG. 3 has a large number of hollow holes C4 formed therein in order to save raw materials and reduce weight.

Furthermore, the mounting fixture A and the wall base α are attached using an L-shaped angle D as shown in FIG. The angle D is an elongated body having an L-shaped cross section, and functions as a connecting member for fixing the fixture A to the wall base α and as a level adjusting member. In other words, if angle C has two L-shaped surfaces as shown in Fig. 5, one of which is the fixing surface D1 and the other surface is the mounting surface D2, the holes 8 are formed on the mounting surface D2 at a pitch of P1. Formed at an equal pitch P2, and welded the fixed surface D1 to the wall base α,
It is fixed with anchor bolts, bolts and nuts, etc., and the fixture A is fixed to the mounting surface D2 through holes 8 and 5 with bolts β.

Effects of the Invention As described above, according to the hard wall material mounting tool of the present invention, it is not necessary to drive nails or drill mounting holes directly into the hard wall material, so that Damage to hard wall materials can be prevented. ■Since the hard wall material and the fixture are engaged with each other through the packing material, the packing material can eliminate the dimensional difference between the engagement groove and the mounting edge of the fixture, allowing the fixture to be fixed without wobbling. Can be done. ■The inclusion of packing material improves sealing and waterproofing properties. ■
Workability is improved because the mounting position of the hard wall material is assigned in advance using angles and fixtures. ■Since the hard wall material is fixed to the wall base using angles and fixtures, it is possible to adjust the level (unevenness) and create a flat wall surface even if the wall base is uneven. ■Since the upper packing material is hard and the lower packing material is soft, the hard upper packing material can withstand the weight of the hard wall material and maintains its sealing properties without breaking, while the soft lower packing material is used to hold the hard wall material. Even if there is some gap between the wall and the groove, the sealing performance will not be compromised, maintaining airtightness and waterproofness, and preventing rattling of the hard wall material. It has the following effects and characteristics.
