Description

[Technical Field]

[0001] The present invention relates to a lightweight building block and a lightweight free-standing partition using the same, more particularly to a lightweight building block that is lightweight and easy to construct and a lightweight free-standing partition using the same. [Background technology]

[0002] Conventionally, a technique such as that shown in Patent Document 1 has been known.

[0003] <Patent Document 1> Japanese Patent Application Laid-Open No. 2-43437 In Figures 1 to 4 of Patent Document 1 and the "Detailed Description of the Invention" (page 5, lower left and lower right columns of the same publication), The document describes a lightweight building block made of a lightweight material, having a through hole (hollow portion (4)) extending vertically in the center, through which adhesive material (mortar or concrete) is poured from above. Also, Figure 7 and the upper left column of page 6 of the same publication state: "Methods for manufacturing structures such as block walls using the lightweight blocks of the present invention include, for example, (i) inserting reinforcing bars (6) fixed to the foundation ground (5) into the hollow portion (4) of the lightweight block (1), as shown in Figure 7, and then pouring concrete, mortar, etc. into the hollow portion (4)." It is stated that: And in the "Effects of the Invention" section: "Furthermore, the lightweight block construction method of the present invention does not require the complicated work of joint finishing, which requires advanced techniques when constructing using conventional concrete blocks, and therefore has the effect of enabling even amateurs to construct the structure easily in a short time." It is stated that:

[0004] However, in such conventional technology, for example, as described above, when an adhesive material such as concrete or mortar is injected into the hollow portion (through hole) of a lightweight block, the lightweight block may float (move slightly upward) when the adhesive material is injected, due to the light weight of the block, which can hinder the smooth stacking of the blocks.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2-43437 Summary of the Invention [Problem to be solved by the invention]

[0006] The problem that the present invention aims to solve is to provide a lightweight building block that can prevent lifting when an adhesive material is injected into a through-hole, and a lightweight free-standing partition using the same. [Means for solving the problem]

[0007] In order to solve the above problems, the lightweight building block of the present invention has the following features: A lightweight building block made of a lightweight material, the lightweight building block having at least one through-hole extending in the vertical direction at the center thereof, through which an adhesive material is poured from above, The through-hole is characterized in that it has a tapered shape in which the lower hole diameter is smaller than the upper hole diameter.

[0008] Due to the above-mentioned structure, the lightweight building block can provide the following effects. For example, when stacking multiple lightweight architectural blocks on a foundation to build a partition or the like, the through-holes have a tapered shape with the lower hole diameter being smaller than the upper hole diameter, so when adhesive material is poured into the through-holes, a force acts on the lightweight blocks through the inner wall surface of the tapered through-hole, trying to push the lightweight blocks downward. Therefore, the adhesive material is prevented from floating up when injected into the through-hole. In this way, the lightweight building blocks of this invention prevent the blocks from floating up when adhesive material is injected into the through holes, making it possible to stack the lightweight building blocks smoothly, and as a result, it becomes possible to easily construct partitions, etc.

[0009] In order to solve the above problems, the lightweight freestanding partition of the present invention is A lightweight freestanding partition comprising a foundation and a plurality of lightweight blocks for construction made of lightweight materials stacked on the foundation via adhesive, At least one of the plurality of lightweight building blocks is the lightweight building block described in claim 1.

[0010] Due to the above-mentioned structure, this lightweight freestanding partition can provide the following effects. This lightweight freestanding partition can be constructed by piling up a number of lightweight building blocks on a foundation with adhesive. During construction, at least one of the plurality of lightweight architectural blocks has a tapered through-hole with a smaller lower hole diameter than the upper hole diameter, so that at least this lightweight architectural block is prevented from floating up when adhesive material is injected into the through-hole. This allows for smooth stacking of lightweight building blocks, and as a result, makes it possible to easily construct a lightweight freestanding partition.

[0011] In this lightweight freestanding partition, A cornice-shaped lightweight architectural block is placed on the top of the lightweight freestanding partition, and the underside of this cornice-shaped lightweight architectural block and the upper surface of the architectural lightweight block placed directly below this cornice-shaped lightweight architectural block can be provided with interlocking recesses and protrusions. With this configuration, a lightweight freestanding partition with a fascia can be easily constructed. [Brief explanation of the drawings]

[0012] [Figure 1] FIG. 1 is a diagram showing one embodiment of a lightweight block for construction according to the present invention, and includes a front view, a plan view, a left side view of the plan view, a right side view of the plan view, a cross-sectional view along the line AA, and a detailed view of part B. [Figure 2] FIG. 1 is a front view of one embodiment of a lightweight freestanding partition. [Figure 3] This figure shows an example of a coping-shaped lightweight block for construction, where (a) is a front view, (b) is a plan view, (c) is a back view, (d) is a left side view of (b), (e) is a right side view of (b), and (f) is an enlarged partial cross-sectional view showing the block in use. DETAILED DESCRIPTION OF THE INVENTION

[0013] The following describes embodiments of the lightweight building block and the lightweight freestanding partition using the same according to the present invention with reference to the drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals, but in some cases the reference numerals are omitted if they are self-evident.

[0014] The lightweight building block 10 shown in FIG. A lightweight building block made of a lightweight material (e.g., polystyrene foam) and having two through holes 13 extending in the vertical direction at the center, through which adhesive material is poured from above, The through hole 13 has a tapered shape T in which the lower hole diameter D1 is smaller than the upper hole diameter D2. The number of through holes may be one, or may be three or more.

[0015] Due to the above-mentioned configuration, the lightweight building block 10 can provide the following effects. For example, as shown in Figure 2, when a lightweight freestanding partition 3 is constructed by stacking multiple lightweight architectural blocks 10 on a foundation 1, the through hole 13 has a tapered shape T in which the lower hole diameter D1 is smaller than the upper hole diameter D2. Therefore, when an adhesive material (e.g., mortar) is poured into the through hole 13, a force acts on the lightweight block 10 through the inner wall surface (T) of the tapered through hole 13, tending to push the lightweight block 10 downward.

[0016] Therefore, the lightweight block 10 is prevented from floating up when the adhesive material is injected into the through-hole 13.

[0017] In this way, according to this embodiment of the lightweight building block 10, floating up when the adhesive material is injected into the through hole 13 is suppressed, making it possible to stack the lightweight building blocks 10 smoothly, and as a result, it becomes possible to easily construct partitions 3, etc.

[0018] For example, as shown in FIG. 2, the lightweight freestanding partition 3 of this embodiment is A lightweight freestanding partition comprising a foundation 1 and a plurality of lightweight building blocks 10 made of a lightweight material stacked on the foundation 1 via an adhesive 14, At least one of the plurality of lightweight building blocks 10 (all of them in the embodiment shown in FIG. 2) is the block 10 described above (shown in FIG. 1).

[0019] With the above-mentioned configuration, the lightweight freestanding partition 3 can provide the following effects.

[0020] This lightweight freestanding partition 3 can be constructed by piling up a plurality of lightweight building blocks 10 on a foundation 1 with adhesive 14 interposed therebetween.

[0021] During construction, at least one of the multiple lightweight architectural blocks 10 (all of them in the embodiment shown in Figure 2) has a tapered through hole 13 with a lower hole diameter D1 that is smaller than the upper hole diameter D2, so that this lightweight architectural block 10 is prevented from floating up when adhesive material is injected into the through hole 13.

[0022] Therefore, the lightweight construction blocks 10 can be stacked smoothly, and as a result, the lightweight freestanding partition 3 can be easily constructed.

[0023] For example, as shown in FIG. 3(f), a lightweight freestanding partition 3 having a coping board is A cornice-shaped lightweight architectural block 10G1 is placed on the top of the lightweight freestanding partition 3 (see Figure 2), and the underside D of this cornice-shaped lightweight architectural block 10G1 and the upper side U of the architectural lightweight block 10 placed directly below this cornice-shaped lightweight architectural block 10G1 are provided with a recess GD and a protrusion 11U that fit together.

[0024] With this configuration, a lightweight freestanding partition 3 with a coping can be easily constructed.

[0025] This will be explained in more detail below.

[0026] The dimensions (diameters) of the upper hole diameter D2 and the lower hole diameter D1 of the through-hole 13 forming the tapered shape T can be set appropriately depending on the shape, material, weight, etc. of the lightweight building block 10. For example, the ratio (upper hole diameter D2):(lower hole diameter D1) can be set appropriately within the range of 100:97 to 100:85.

[0027] In this embodiment, the lightweight building block 10 has recesses 12D, etc. or protrusions 11U, etc. on its top surface U, bottom surface D, left side surface L, and right side surface R, which fit into protrusions 11U, etc. or recesses 12D, etc. provided on the bottom surface D, top surface U, right side surface R, or left side surface L of an adjacent lightweight building block (see, for example, Figure 2). The rod-shaped support member 2 (see FIG. 2) passes through the through hole 13 provided in the center part C in the left-right direction in the vertical direction, and an adhesive material (for example, mortar) is poured into the through hole 13.

[0028] Because of the above configuration, for example, as shown in Figure 2, when a partition 3 or the like is constructed by stacking multiple lightweight architectural blocks 10 on a foundation 1 on which rod-shaped support members (e.g., reinforcing bars) 2 are installed, the lightweight architectural block 10 with the rod-shaped support members 2 passing through the through holes 13 can be connected to the adjacent lightweight architectural block 10 by fitting the recessed portion 12D, etc. and the protruding portion 11U, etc. provided between the two lightweight architectural blocks 10, and with the position maintained in this way, adhesive material can be poured into the through holes 13.

[0029] In addition, the through hole 13 has a tapered shape T in which the lower hole diameter D1 is smaller than the upper hole diameter D2, and the recessed portions 12D etc. and the protruding portions 11U etc. fit together, which more reliably prevents the lightweight block 10 from floating up when the adhesive material is poured into the through hole 13.

[0030] In FIG. 1, 11U1 denotes bulging portions provided on both sides (front and back) of a protruding portion 11U on the top surface of the block. The bulge 11U1 strengthens the bond between the protrusion 11U and the recess 12D on the bottom surface of the block, and more reliably prevents the lightweight block 10 from floating up when the adhesive material is poured into the through-hole 13.

[0031] In FIG. 1, 11L1 is a bulge provided at the tip (left end) of the convex portion 11L on the left side of the block, and 12R1 is a bulge provided at the tip (right end) of the concave portion 12R provided on the right side of the block. These bulging portions strengthen the bond between the convex portion 11L and the concave portion 12R, and more reliably prevent the lightweight block 10 from floating up when the adhesive material is poured into the through-hole 13.

[0032] The lightweight building block 10 can be made of a known lightweight material (such as polystyrene foam) that is sufficiently lighter (at least half the weight) than known concrete blocks.

[0033] The recesses or protrusions of the lightweight building block can be provided at appropriate locations depending on the use or location of the lightweight building block. The same effect can be obtained even if the top, bottom, left and right unevenness are reversed.

[0034] The adhesive material poured into the through-holes 13 may be a known adhesive material (for example, mortar). Regarding the first layer of lightweight building blocks, they are stacked on the foundation 1 with adhesive 14, and it is desirable to use quick-drying mortar as the adhesive material so that leveling can be easily and quickly performed.

[0035] The lightweight blocks that make up a structure such as a partition can be joined together with an adhesive as needed. In particular, it is desirable to glue adjacent lightweight blocks together as needed.

[0036] All structures are covered with a net material of suitable strength (for example, fiberglass netting), and then mortar (Cationite) is applied on top of the net material to harden the base, followed by another coat of mortar mixed with a waterproofing agent (for example, Manol waterproofing material), and finally a finishing material is applied by painting or other means.

[0037] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the gist of the present invention. [Explanation of symbols]
