Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for fixing a plurality of blocks to an installation surface by using a fixture when continuously installing a plurality of blocks, and to a block used in the method.

[0002]

2. Description of the Related Art As a block fixed to an installation surface by a fixture, there is a block for a sidewalk boundary, that is, a curb block installed so as to border a sidewalk along a boundary of a road. In the case of this conventional curb block, an insertion hole through which a bolt is inserted is provided as a fixture for fixing the curb block to the installation surface, penetrating the block vertically. However, as a result, a) the bolt insertion hole must be formed in the block, which complicates the mold structure and lowers productivity. B) The strength of the block decreases at the bolt insertion hole, resulting in breakage. C) The insertion hole is closed by a washer due to bolting, and mortar cannot be injected into the hole.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and its object is to eliminate the problem seen in the conventional block, that is, to achieve the same high level as the block having no insertion hole. It is an object of the present invention to provide mortar to a fixed portion without increasing the strength of a block while having productivity.

[0004] It is another object of the present invention to streamline the process by allowing mortar injection to be performed simultaneously with joint formation.

It is also an object of the present invention to make the block removable so that it can be removed without damaging it.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a structure in which end faces of blocks to be continuously installed are abutted to each other, fixing means are arranged on the end faces of adjacent blocks, and a tip of the fixing means is placed on an installation surface. In addition to the above, the other end of the fixing means is hooked to both adjacent blocks and fixed in common, thereby constructing a block end fixing method.

In order to carry out the above-mentioned construction method, a concave through groove for arranging the fixing means is formed on the end face of the block body, and two through grooves formed on the end faces of the adjacent block bodies are put together to fix it. It is desirable to use a block having a structure capable of forming a single entry port for the means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The end fixing method according to the present invention is a type of a method for fixing a plurality of blocks to a mounting surface 10 by using fixing means 20 when a plurality of blocks are continuously installed.

The main bodies 11 of the individual blocks installed by this method are arranged continuously with their end faces 12 facing each other (see FIG. 1). However, an appropriate space 13 is provided between the block bodies 11, 11 arranged continuously (see FIG. 3). The space 13 is a space where the fixing means 20 is arranged. The fixing means 20 placed between the end faces of the adjacent block bodies 11, 11 locks the tip thereof to the installation surface,
At the same time, the other ends are simultaneously connected to the adjacent block bodies 11, 11. That is, two adjacent block bodies 1
1 and 11 are commonly fixed by one fixing means 20.

The blocks used in the end fixing method of the present invention can have various forms as will be described in detail later. However, in the case of a block at the end of a continuous block row, only one end face 12 is provided. It may not be necessary (FIG. 5 (g) and the like).
A particularly concave portion 14 can be formed in the end face 12 for disposing the fixing device 20.

The fixing means 20 is fixed at its tip to the installation surface side, and is hooked or hooked to the adjacent block at the other end. Hooking means is required. As such a fixing means 20, for example, a set of a bolt 21 serving as a fixing tool and an implanted nut 22 serving as a fixing partner can be used (FIG. 2). Reference numeral 23 denotes a washer, which increases a locking area with an adjacent block.
This washer 23 or bolt head is hooked on the adjacent block,
A means for fixing them in common is configured. Bolt 2
1 is screwed into a nut 22.

A step 15 can be provided on the end face 12 of the block main body 11 for engaging the fixing means 20 (the head of the bolt 21 or the washer 23) with the block main body 11. It has a size and shape capable of exerting a sufficient fixing force on the block body 11 through the washer 23 of the fixing means 20, and facilitates the operation of pouring the mortar around the bolt. The fixing means 20 is not limited to bolts and nuts. The fixing means 20 can be inserted into and connected to a fixing partner of the installation surface 10 from between adjacent blocks. It may be specially made so that it can be fixed.

In order to carry out this method, as shown in FIG. 1, blocks to be continuously installed are installed on an installation surface 10 so that their end surfaces 12 abut against each other, and between the end surfaces 12 of adjacent blocks. The fixing means 20 is arranged, and the front end thereof is connected to a fixing partner such as an insert nut 22 implanted on the installation surface 10 side, and the other end is hooked to an adjacent block. At that time, in order to prevent the mortar from clogging the nut 22, the mortar 29 is laid after the bolts 21 are erected, and the block is supported by supporting means until the mortar 29 is stabilized.

Reference numeral 24 denotes a wedge-shaped support for supporting the bottom of the block, and reference numeral 25 denotes a pin-shaped support, which is firmly attached to the block via another support piece 26. A hole is provided in the side surface of the block body 11 for attaching the pin-shaped support 25. The bolt 21 is filled with mortar and is integrated with the mortar at the same time as filling the joint around the bolt 21, so that it is not necessary to tighten the nut 22 tightly.

The blocks used in this end fixing method will be described in more detail. Basically the block body 1
1 has a through groove 16 formed in a concave shape for arranging (the bolts of) the fixing means 20 on the end surface 12, and the through groove 16 formed on the end surface 12 of each block main body 11 has the through groove 16 formed therein. It has a structure capable of forming one insertion opening 17 through which the fixing means 20 is inserted by combining two pieces by the continuous arrangement. The through groove 16 is provided on the top of each insertion port 17.
The stepped part 15 which expanded is also formed. When the step 15 is formed in a mortar shape, mortar flows easily.

Each block is a low-profile normal low block 11a shown in FIG. 5A, a normal standard block 11b in FIG. 5B, and a normal high block 11 in FIG. 5C.
c, FIG. 5 (e) with the vehicle entering block 11 d of FIG. 5 (d) provided with an inclination connecting the block and the ordinary type block.
5e, a drain block 11f shown in FIG. 5 (f), a terminal block 11g placed at the end of the above-mentioned block row shown in FIG. 5 (g), and a box upper block 11h combined with a water collecting box. (FIG. 5H). Reference numeral 18 denotes large and small drainage ports, and 19 denotes a bolt insertion hole, which is provided only on the terminal block for bolting similarly to the conventional type.

Each of the blocks 11b shown in FIGS.
11d to 11h have the shapes shown in FIGS. 6 (a) to 11 (b). As can be understood from these figures, the various deformed blocks 11d to 11h have the same height h and width b as the standard type block 11b, and have a half-length entry block 11d, a slightly shorter terminal block 11g, and a slightly longer length. Except for the long block 11h, the other parts have a certain length. However, since the shapes and dimensions of the various blocks are determined arbitrarily, what is necessary for each block is a concave through groove 16 provided on at least one end face.

These various blocks 11a to 11h are
It is combined with a lower block 30 which constitutes a culvert or the like as an overhead. 12 to 14 show examples of each combination. FIG. 12 shows an ordinary standard block 11.
b, the rubbing block 11e and the block 11d for access to the sidewalk are continuously formed by the fixing means 20 on the lower block 30 constituting the culvert having the longitudinal slits 31 on the upper surface thereof, with the upper surface thereof as the installation surface 10. 1 shows the construction example 1 installed in the first embodiment. The length of the standard block 11b is one half that of the lower block 30, and the entry block 11d
Is a half of the length, each block is unified with a length that is an integral multiple of the length of the entry block 11d.

FIG. 13 shows a lower block 30 installed on a flat road surface and a drain block 11f and a standard block 1f.
14 is similar to the example of FIG. 12, except that the block 1b and the terminal block 11g are installed continuously to form a boundary block, and FIG. 14 is similar to the example of FIG. The construction example 3 in which the curb block construction was performed is shown.

[0020]

As described above, the present invention is constructed and operated as described above, so that the conventional insertion hole which penetrates the intermediate portion of the block and lowers the strength becomes unnecessary, and the productivity can be improved. There is no danger of strength reduction, and the mortar can be injected without any trouble because the end face is a fixed part. In addition, joints can be formed simultaneously with mortar injection, so the number of steps is reduced, shortening the construction period and facilitating construction. Can be realized. Further, since the fixing means is arranged between the blocks, the blocks can be removed without damaging the blocks, and the reusing process of the blocks can be opened.
