Abstract

PURPOSE:To prevent breakage of incombustible plate due to driving during construction work by installing a protrusion at one end of incombustible plate and a U-shaped engaging groove at the other end thereof, and engaging the protrusion with the engaging groove by using a holding member with a T-shaped cross section. CONSTITUTION:Male and female connecting portions 4, 7 are disposed on an incombustible plate 1. At the male connecting portion 4, a fixing groove 6 is formed by an inclined side wall 3 inclining outward and a protrusion 5 whose lower end extends on the inner and back side in an inclined form. The female connecting portion 7 is formed by an inclined side wall 3, an engaging groove 8 whose lower end is bent in a U shape, and a hollow portion 9 disposed in the longitudinal direction. The protrusion 5 is engaged with the engaging groove 8 by using a holding member 17 with a T-shaped cross section. Further, the holding member is fixed to a fixing member 11. Thus, the incombustible plate is not installed by driving, but grasped by a securing member 10, by which the breakage of incombustible plate can be prevented, and the work can be done so that the unevenness of backing is accommodated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connection structure useful for fixing hard noncombustible plates.

(Prior art) In order to connect this kind of noncombustible boards, there are two methods: - Fix the male part directly with nails, or hold it down with special metal fittings as in Publication of Utility Model Publication No. 58-18515, ■ Decorative surface of the noncombustible board There is a method in which a nail or the like is hammered into the head, and a connecting structure constructed from a connecting member, a backing material, and a caulking material as in Japanese Utility Model Publication No. 1-1339.

[Problem to be solved by the invention]

However, this type of connection structure has drawbacks in the following points. That is, the non-combustible board in case (3) had poor impact resistance and was often broken when being driven with a hammer or the like. In addition, in case (2), there were more damages due to pouring than zero, and moreover, the pouring had to be done carefully, resulting in inefficiency, and furthermore, there were disadvantages such as damage to the aesthetic appearance due to dents. Furthermore, (2) requires a backing material and a caulking material at the connecting portion, and has the disadvantage that the caulking material is exposed on the decorative surface.

Furthermore, it is impossible for this kind of hard flame retardant board to deal with unevenness in the base, and it is necessary to eliminate the unevenness before installation. Means for Solving] In order to eliminate such drawbacks, the present invention provides a protruding piece protruding inwardly on the back surface at one end of the noncombustible plate, and a locking groove formed in a U-shaped cross section at the other end. The projecting piece and the locking groove are locked with a holding member having a substantially T-shaped cross section, and the engaging piece of the holding member is engaged and integrated with the fitting groove of the fixing member fixed to the base. By fixing the noncombustible plates to the base, we propose a connection structure for noncombustible plates that can be reliably constructed by adjusting the degree of engagement without being affected by unevenness of the base.

[Example] Hereinafter, an example of a connection structure for noncombustible plates according to the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram showing an embodiment of the above invention, where soil is a noncombustible board, ri is a fixture, α is a base, and β is a fixture. To explain further, the top of the noncombustible plate is made of ceramic or ceramic material (including fired materials), as shown in Figure 2, and is made of dense or hollow material formed by pressing, extrusion, etc. according to the desired shape. It is formed from one type of body. That is, the top of the noncombustible board consists of a decorative surface 2 and a female connecting portion formed on both of its opposing longitudinal inclined side walls 3, and a male connecting portion 4 is formed on the outwardly inclined inclined side wall 3. , a protruding piece 5 that projects from the lower end of the inclined side wall 3 in an inwardly inclined manner, and a fixing groove 6 formed by the protruding piece 5. 3, a locking groove 8 in which the lower end of the inclined side wall 3 is bent inward to have a substantially U-shaped cross section, and a hollow portion 9 formed continuously along the longitudinal direction. The fixture is composed of two members, a fixing member 11 and a restraining member 17 as shown in FIGS. 3(a) and 3(b), and the fixing member 11 has a horizontal fixing piece 12 and one end of the fixing piece 12 A fitting consisting of a fitting groove 15 formed with a U-shaped cross section by the vertical piece 14 with two upwardly protruding edges and the vertical piece I4, and a wavy fitting claw 16 formed on the inner surface of the fitting groove 15. It consists of a joining part 13 and a holding material 1.
7, a short horizontal locking piece 18; and an engaging groove 19, which has one end edge of the locking piece 18 bent downwardly and shaped to be able to engage with the protruding piece 5 on the noncombustible plate. , an engaging piece 21 and an engaging piece 2 that hang downward in the middle of the engaging piece 18 and the engaging groove 19.
1, and a wavy engaging portion 22 formed in the engaging portion 20.

As shown in Figure 1, this attachment allows the top of the non-combustible board to be fixed to the base α without the need to drive the fixture β onto the non-combustible board, and also allows for fixing the top of the non-combustible board to the base α when there is an uneven surface on the base α. However, construction is possible depending on the degree of engagement between the fitting part 13 of the fixing member 11 and the engaging part 20 of the restraining member 17, and the locking piece 18 is engaged with the locking groove 8 of the noncombustible plate t. The groove 19 is inserted into and integrated with the protruding piece 5 on the noncombustible board, and the engagement piece 21 is inserted and engaged with the fixing member 11 installed on the base α to fix the noncombustible board to the base α. The fixtures are made of metal or synthetic resin, such as aluminum or plastic extrusions, or roll-molded iron plates (not shown). The base α may be made of wood, concrete, or steel, and a rim or the like may be added as necessary.

Next, a construction example will be briefly explained.

Now, it is assumed that a non-combustible board as shown in FIG. 2 is installed horizontally on a base α as shown in FIG. 1, and is connected with fixtures 10 to form an outer wall. Therefore, a starting material (not shown) is fixed to the base of the base layer α, and the fixing member 11 is fixed at a predetermined pinch position from the starting material using a fixing device β made of a screw. Next, the starter material is engaged with the locking groove 8 of the female connecting portion 7 on the noncombustible plate, and a plurality of restraining materials 17 are hooked onto the protruding piece 5 of the male connecting portion soil to fix the material. The first stage is constructed by inserting and engaging the 17 engaging pieces 21 into the fitting grooves 15 of the fixing member 11. In the second and subsequent stages, the locking pieces 18 of the restraining material 17 are used instead of the starting material in the first stage to sequentially work on the noncombustible board up to the girder. Although not shown in the drawings, caulking material or the like is planted in areas where there is a problem with waterproofness.

(Other Examples) What has been described above is only one example of the connection structure of noncombustible plates according to the present invention. Figures 5(a) to (e), Figure 6(a)
The fixing member 11 and the restraining member 17 as shown in ) to (e) can be used to form the noncombustible board connection structure according to the present invention.

〔Effect of the invention〕

As mentioned above, according to the connection structure of non-combustible plates according to the present invention, it is possible to
Since the parts are clamped using split-type fixtures, there is no damage to the non-combustible board due to pouring during construction. ■Since the restraining material is short and partially locked, the degree of engagement (depth) can be adjusted in the area where the restraining material is present, so construction can be carried out to accommodate uneven groundwork. (2) Since the restraining material is only partial, even if the non-combustible board curves somewhat in the longitudinal direction, there will be no problem in fixing it, and of course the non-combustible board will not be destroyed. It has the following characteristics and effects.
