Description

[Detailed description of the invention] [Industrial application field] This invention relates to a composite floor plate made of aluminum.

[Conventional technology and its problems]

Double floors for wiring are often used these days. As a double floor for wiring, it is made of non-combustible material and is strong; it is dust-free and clean; it is conductive and does not accumulate static electricity; it is easy to cut on-site and border construction is easy; and it is lightweight and easy to transport and install. - Aluminum is said to be the best choice because it is lightweight and puts less stress on the body and foundation. However, the conventional double bed made of aluminum is based on the Guika Kuto Kaigata, and the Kaigata IAI machine is large and expensive, the mold is expensive, productivity is poor, and some reverse tapers are difficult to produce. - Due to poor molding accuracy and the need for triangulation, the aluminum floorboards ended up being expensive and difficult to use.

In addition, when installing power distribution equipment such as an outlet, cut out a hole in the top surface of the floorboard and insert the outlet a into the hole.
I dropped it in and installed it. Providing holes in finished die-cast floorboards is laborious and costly, and there is also the problem of cutting off ribs that are necessary for strength, so improvements were needed.

The purpose of the present invention is to solve these problems and provide an aluminum double floor that is inexpensive and easy to wire.

[Means to solve problems]

To achieve this objective, the present invention first uses an aluminum extrusion product.

Normally, the floorboards of a double floor are 50 to 60 cm square, but extruding such wide sheets is technically difficult, the molds are very expensive, and it is difficult to ensure the precision of the product. Therefore, in this invention,
A relatively narrow strip-shaped disk having a width of lO to 25cII+ is used as a reference disk.

A high-strength harmonica-shaped square body is used as the reference plate body, and a fitting groove or a fitting convex line continuous in the longitudinal direction is provided on the side surface during the extrusion process. A plurality of these standard board bodies of the same length are joined in parallel using a fitting function to form a composite floorboard.

[Effect]

Since this invention is an aluminum extrusion molded product,
In addition to having the basic properties of aluminum, it requires less expensive production equipment and molds than die-cast products, has good production efficiency, and is known for its low cost as mass-produced products such as aluminum sashes. Since any cross-sectional shape can be obtained during extrusion molding, a shape with optimal strength/cost can be planned.

In addition, when combining them, it is easy to use a mating uneven strip, and since they can be inserted and removed by sliding, it is extremely convenient for forming holes for wiring. This invention will be explained in detail below with reference to the drawings. [Example 1] A reference plate body 1 is shown in FIG. Made of extruded aluminum, the planar shape is a rectangular shape, the cross-sectional shape is partitioned by ribs l1, and has a harmonica-like shape with seven continuous holes l2 arranged in parallel in the longitudinal direction, with inverted tapered fittings on both sides. A matching groove 13 is formed over the entire length. The width is 20cm, the board thickness is 25ms, the length is 50am, and the wall thickness is double layered.

Long I M What is shown in FIG. 2 is the joining disc body 2. It is a product made of the same material and molded as the reference plate body, and has fitting protrusions 21 formed over the entire length on both sides to fit into the fitting grooves of the reference plate body. The width of the main body is 10c+s, the board thickness is 25w, the length is 50cm, and the wall thickness is 2mm. As shown in Figure 3 of Fukkin Babuto, there is one reference board 1 on each side.
, one joint plate body 2 is arranged in parallel in the center, and the fitting recess iJil
3 and the fitting protrusion 2l are fitted to each other to form the composite floorboard A of the present invention. The size of the composite floorboard is 50 Clm square.

The fitting method does not need to be limited to grooves and protrusions; for example,
Fitting grooves may also be provided on the joining disc body, and protruding rods or the like may be used that fit into the grooves on both opposing sides.

To construct a double floor using the Toyo-Ko I-Fu composite floorboard A, the method is not prescribed, but as shown in Fig. 4, a long hat-shaped joist 3 lifted up by legs 31 is used. It is constructed between the support edges 32 of the A wiring space 5 that extends over the entire surface is formed between the composite floorboard A/joist 3 and the floor surface 4.

[Example 2] ・AB Figure 5 shows a composite floor board B with wiring holes, in which one joining board 2 is arranged in parallel in the center of two reference boards 1, and the fitting groove and the fitting groove are connected. The mating protrusions are fitted together and joined together, but the length of the central joining disc body 2 is locm shorter. A 10 cm square wiring hole B1 is formed at the edge of the joint board body.

Various wiring devices such as an outlet can be installed in this wiring hole. If a projection is provided on the side surface of the wiring device to fit into the fitting groove of the reference board body, the installation work will be extremely easy.

[Example 3] A composite floor board C with a lid is shown in Figure 6 of the above-mentioned Example 1.
As in 2, two reference disc bodies 1 and one joint disc body 2 are fitted in parallel, but the central joint disc body is cut transversely at a point 5 cm from the end, and the lid C1 is Form. The lid slides along the fitting unevenness and can be attached and detached freely.

Once the lid is removed, an arch-shaped notch C3 is provided at the end facing the cutting line C2 of the joint disc main body, and the cord C4 is passed through, and then the lid can be fitted again. The location and number of cuts are arbitrary.

In the embodiment, two comparatively wide discs and one narrow disc were combined, but this selection is free, and only narrow discs may be arranged side by side. The width of the currently popular double-walled electrical outlets is about 10 cm, so the joint board has a width of 10 cm.
A width of about m is desirable.

Although there is no particular restriction on the order in which they are arranged in parallel, it is desirable for the boards at both ends to be installed on the joists in view of the supporting force, so uncut boards are generally used.

Aluminum is relatively easy to cut, so instead of cutting the joining board short and placing it in advance, it is necessary to cut the entire joining board into a standard length.
It is also possible to plan to cut the material at J11 and then cut it on site if necessary.

〔effect〕

Since the present invention is structured in this way, it has the following features.

■ Made of non-combustible material and strong - Dust free and clean - Conductive and does not accumulate static electricity - Easy to cut on site and border construction - Lightweight and easy to transport and install - Lightweight and easy to use for construction and construction It retains the advantage of aluminum flooring, which is that it requires less stress.

■ Since it is made of extruded aluminum, the mold is simple and inexpensive, and mass production is possible through continuous production, so it is much cheaper than die-cast products.

■ Once an extrusion mold is prepared, mass production is possible using an existing extrusion molding machine, making it possible to commercialize with less initial capital investment.

■ Since any cross section can be obtained by extrusion molding, it is possible to plan a shape that is consistent in terms of strength and performance.

■ The rectangular tubular body with a harmonica-shaped cross-section has multiple ribs that connect the front and back surfaces together, so the front and back surfaces are pulled together.
It works effectively as a compression material and has great resistance to deflection in the longitudinal direction.

■ Because it has a harmonica-like cross-sectional shape, the moment of inertia in the direction perpendicular to the extrusion direction is large, and even if the load is concentrated at the center of the short axis, the plate will not warp in the short axis direction.

■ Since the fitting unevenness is formed using the freedom of the cross-sectional shape, compounding is easy.

■ It is possible to slide the boards together using the mating unevenness, and the material is aluminum and easy to cut, so even if you use a short joined board or a composite floor board without a lid, it is easy to make wiring holes and lids. This is convenient because it can be easily formed.
