Description

[Detailed description of the invention] A cross section provided on the side edge of a waterproof plate-like body using the pressing force of a spring provided inside a metal fitting fixed to a metal member fixed to a building structure such as a wall plate. The present invention relates to a method for attaching a plate-like object in which a hook-shaped rising engaging portion is pressed and held against a T-side bent protrusion of a mounting hardware to securely hold the plate-like object.

In buildings constructed of reinforced concrete, the conventional method of attaching plate-shaped bodies to the ceiling or wall panels is to overlap the edges of the plate-shaped bodies and tighten them with fasteners such as bolts or nuts, or to secure them with solder joints. A method of assembly was used.

When attaching a plate using this method, many parts such as bolts are required, and installation is difficult in difficult-to-reach places such as ceilings, takes a long time, and requires a lot of concrete. When installing a waterproof plate-like body to prevent water leakage such as rainwater from entering the room from dripping onto important items such as equipment placed indoors, the gap between the mounting hole and bolt of the part fixed with screws, etc. There was a drawback that water leakage could occur.

In order to solve the above-mentioned problems, the present invention has a cross-sectional hook shape provided on the side edge of a waterproof plate-like body to a bent protrusion on the lower side provided on the mounting hardware of an additional issue member fixed to the structure of a building. The object of the present invention is to provide a method for attaching a plate-shaped body in which a temporary payment body is fixed to a metal fitting by engaging a rising retaining portion and pressing it with a pressing spring fixed inside the fitting. The drawings will be explained in detail below.

Fig. 1 (,-1) A block diagram of a ceiling board according to the present invention, Fig. 2 is a view of the ceiling board 1 and 11 according to the present invention, Fig. 3 is a partially enlarged view of Fig. 2, and Fig. 4 is a block diagram of a ceiling board according to the present invention. FIG. 3 is a front view, and FIG. 5 is a diagonal R79 view of the waterproof plate-shaped body and one-stage metal fitting used in the present invention.

In Figures 1 to 5, I is a building structure such as a ceiling or a wall; Parts, 3
is attached to the mounting part 2 (1-inch hardware, made of a short piece of steel of a predetermined length, has a bent protrusion 3C on the lower side 3B, and is formed narrower than the upper side 3A. (See Figure 5)
. Reference numeral 4 denotes a waterproof open plate-like body, and one side edge (a step-shaped engagement part 4B having a hook-shaped cross-sectional rising retaining part 4A and a shoulder part 4C on the other side edge) is attached to the plate-like body 4. When connecting, the engaging part 4 T3 of the second plate-like body 4 is attached to the retaining part 4A of the first plate-like body 4 so that it can be easily overlapped and secured from the same direction. 4C is provided on the engaging portion 4B (see Fig. 5).5 is a round pusher.

It is a leaf spring, and the inner part of the upper side 3A of the hardware 3 is
T! I is identified by riveting or welding (5A) in a predetermined position, and the lower end 5B extends in the axial direction of the mounting hardware 3 (see FIG. 4). 6 is the bending protrusion 3 of the mounting hardware 3 with banking.
It is inserted between C and the engaging portion 48 or 41 of the plate-shaped body 4 to prevent them from becoming loose.

As shown in FIGS. 3 and 4, a mounting part 2 is fixed at a predetermined position by nuts or the like to a hanging member 1 fixed to a concrete building structure (for example, a ceiling), and is riveted or welded to a predetermined position. etc. (=j) Fix the hardware 3, and engage the upward engaging portion 4A of the plate-shaped body 4 37i with the bent protrusion 3C of the lower side 3B of the mounting hardware 3 via the backing 6. At this time,
The top of the rising engagement part 4A is hooked onto the bent protrusion 3C of the mounting hardware 3 by pushing out both F ends 5B of the presser plate spring 5 provided inside the upper side 3A of the supplementary hardware 3 as shown by the dotted line in Figure 4. Therefore, after being hooked, the rising retaining portion 4A is suppressed downward by the pressing force of the presser plate spring 5. As a result, the rising retaining portion 4A of the plate-shaped body 4 is securely fixed to the bent protrusion 3C of the mounting hardware 3. Similarly, in addition to the plate-shaped body 4, the stepped engagement portions 4B provided on the edge of the plate-shaped body 4 are also bent at predetermined positions (at each width interval of the plate-shaped body 4). Engage with the protrusion 3C. As shown in FIG. 1 to FIG. (・τ, one bent protrusion 3CI71 of the mounting hardware 3: is 1ii1 on the right side of the drawing.
l) The raised engagement portion 4A of the temporary payment body 4 is engaged, and the
The stepped engagement portions 413 of the plate-shaped body 4 of 2(, ko/=f'till) are overlapped and engaged.

Therefore, since the 74 part 4 of the stage f1 engagement part 41 serves as an allowance, the r-heel engagement part 4 and the stage 1 soft engagement part 419 overlap. Even if there is some error between the two, the backing 6 will engage without any problem.
If it is interposed, it is possible to prevent looseness and wobbling, which is good.

J'f 3=: When they are arranged in a row in the H and T directions, they can be lined up without any gaps by overlapping their ends.

In the example of City Water, the supplementary hardware 3 is described as a short piece of a predetermined length, or the supplementary hardware may be configured as a long bar (represented by the yellow line in Figure 5) to which the mounting member 2 is connected. It is possible.

In this case, the side edges of the plate-shaped body 4 are held together over the entire length, so that the engagement becomes more reliable.

In addition, as is clear from Fig. 4, the mounting hardware 3 can be
The position where the presser plate spring 5 is attached and the position where the presser plate spring 5 is fixed to the hardware 3 may be separately provided at different positions, or if necessary, they may be fixed together with the planes at the same position.

Furthermore, the shapes of the retaining leaf spring 5 and the handle (1) may be changed, for example, by using a vortex as a leaf spring, or by using a vortex as a spring, as long as it does not depart from the gist (actions and effects) of the present invention. It is also possible to use a frame with a Z-shaped cross section.

Up to this point, we have explained how to attach a ceiling board, but it can also be used as a wall board in the structure of a building.
This method does not require the preparation of special parts, and the plate is attached to the bending protrusion provided on the lower side of the hardware by the pressing force of the presser plate spring installed on the hardware. The plate-shaped body is suppressed and fixed by engaging the vertical engaging portions of the plate-shaped body, or the parts used for the plate-shaped body, 1/1 part (me, ← J hardware, etc.) are manufactured at the factory. At the site, the ceiling board is fixed and held on the concrete structure (ceiling) by simply engaging the engaging part of the plate-shaped body with the bent protrusion of the mounting hardware. Therefore, it is efficient and can be easily worked in difficult places such as Otsuki. Therefore, even in existing buildings, extra space is not required for the work, and the installed equipment does not need to be moved. Since the plate-shaped body is secured by being pressed by the force of the presser plate spring, the plate-shaped body will not shift or come off even in the event of large vibrations such as an earthquake.

Furthermore, since a waterproof plate-like material is used and there are no screw holes or other holes in the cut-out part, it will prevent water from entering the concrete and prevent water from leaking indoors. As a result, wet water will not drip onto important items such as equipment installed in the room, and accidents with equipment due to water leakage can be prevented.
