Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a set of building material blocks connected by a positioning auxiliary plate and a manufacturing method thereof.

[Conventional technology]

As shown in Figure 9, such blocks are known to be made by filling a lightweight concrete material into a mold that forms the surface layer a made of plastic such as PVC film and solidifying it.
It is especially known as a flooring material for offices and factories that use a lot of office automation equipment. The block surface layer a is integrated with the positioning connection part, and the space C created above the connection part is
When this block set is laid down, a wiring groove for the base layer is formed. A decorative floor board can be placed on top of the blocks, or a cover material can be attached to cover the grooves.

However, in such a block assembly, the plastic profile material a of the surface layer must be manufactured in advance, and high-speed production is not possible. On the other hand, the part of the plastic mold material a that corresponds to the side surface of the block is not necessarily necessary, and an unnecessary part is purposely provided with a complicated shape, which is uneconomical.

[Problem that the invention seeks to solve]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide the above-mentioned building material block and its manufacturing method, which can be produced at high speed using an apparatus with a relatively simple structure.

[Means for problem solving]

In order to achieve the above object, the present invention has a building material block set in which a plurality of building material blocks made of cement mortar are arranged at intervals and connected by a connecting plate, and the connecting plate is attached to the bottom of the building material block. It is an object of the present invention to provide a set of building material blocks characterized in that the openings are smaller than the bottom surface, the openings are filled with the material of the building material blocks, and the blocks are thereby connected by connecting plates.

In addition, the present invention supplies cement mortar material to each of the above-mentioned spaces of a mold having a plurality of molding spaces, then arranges a connecting thin plate material covering all of the plurality of molding spaces on the upper surface of the plurality of molding spaces, and connects the upper and lower molds. The present invention aims to provide a method for manufacturing a set of building material blocks connected by auxiliary plates, which is characterized in that the blocks are closed and compression molded while forcefully squeezing water.

[Function and Examples]

Other features of the invention will be explained in more detail with reference to the accompanying drawings, which illustrate an embodiment of the product of the invention and the apparatus for use in the method of manufacturing the product.

1 to 6, three construction material block sets according to the present invention are shown.
An example is shown below. The building material block assembly of the first embodiment shown in FIG. 1 (plan view) and FIG. , which are joined together at the same time when the block is formed by a connecting plate 2 made of stainless steel or the like. Connecting plates include cloth and rubber sheets, as well as nets. An opening 3 having the same shape as the bottom surface and slightly smaller than the bottom surface of the forming block 1 is provided in advance in the connecting plate at a location where it contacts the bottom surface of the molded block 1. The vertical cross-section of the opening 3 is shaped downwardly in the figure to prevent separation of the connecting plate 2 and the block 1 when the cement mortar material at the bottom of the block fills the opening 3 due to compression molding.

In the second embodiment shown in FIGS. 3 and 4, a plurality of openings 3 are provided on the bottom surface of one block.

In this case, it is possible to reduce the separation of the block 1 and the connecting plate 2 when the block 1 is cut at the portion indicated by the dashed line 4 and used at the edge of the placement location.

In the third embodiment shown in FIGS. 5 and 6, block 1
A reinforcing plate 5 is simultaneously fixed to the upper surface of the plate by compression molding. This reinforcing plate can be made of various materials. Plastic materials, metal nets, and metal plates can be used. The metal plate may be plain, but those provided with a large number of protrusions by welding or stamping will ensure a secure connection to the block surface.

The method of the present invention for manufacturing the product according to the present invention can generally be manufactured using conventional cement mortar manufacturing equipment, and the specific method will be explained below with reference to the embodiments shown in FIGS. 7 and 8. According to FIG. 7, the lower die main body has a plurality of, for example, nine, square prism-shaped upper columnar portions 1) each having a flat upper surface that forms the upper surface of the molded product block 1;
The space between these columnar parts and the outside of the entire columnar group is occupied by a formwork 12 that can be moved up and down by a cylinder, and this formwork 12 has nine pieces that fit into the upper columnar part 1) of the lower mold body. It defines a molding compartment 15 having an opening 13 and distributing mortar material 14 .

On the other hand, the upper mold 16 can be used as it is, and the lower molding surface is covered with dehydrating cloth 17 and gold 1.
)1ii1B (or a water draining iron plate 19 may be used in addition to this) is attached, and water squeezing holes 19 are bored in the molding surface, and the molding surface is used as a water squeezing chamber (or water squeezing channel). ) 21. This water squeezing chamber 21 is connected to a vacuum blower (not shown) via a suction port 22 to supply negative pressure to the molding surface and squeeze water during press molding.

This technique is as shown in Japanese Patent Publication No. 54-20209 and other publications.

FIG. 8 is a sectional view of a manufacturing apparatus showing another embodiment of the product and its manufacturing method according to the present invention, and the upper mold is the same as that in FIG.
Before supplying the material 13 to the molding surface of the upper columnar part 1) of the lower mold, a reinforcing material 23 (regardless of whether it is non-perforated or perforated) is placed, or the reinforcing material (it can be carried out even if there is no reinforcing material). If the upper columnar part 1) is a net or perforated plate,
By providing a water extraction hole 24 on the molding surface and communicating with a vacuum blower through a suction pipe 25, it is possible to improve the quality and efficiency of molding by applying a reinforcing plate to the top surface of the product according to the present invention or by squeezing water from that surface. This water squeezing device can also contribute to mold release by blowing air when the upper mold is raised.
