DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retaining wall block which is piled up on a slope of a cliff or embankment to prevent collapse of earth and sand, and an assembling apparatus thereof, and is particularly suitable for a large block which is difficult to transport.

[0002]

2. Description of the Related Art In a conventional retaining wall block, a thick plate-shaped front member which becomes a surface of a slope after construction, a thick plate-shaped rear member located behind the block, and a connecting portion connecting the two thick plate-shaped members are made of concrete. It is integrally molded, and a gap is formed between the front member and the rear member.

When a block having such a configuration is produced in a factory, the block is loaded on a truck, transported to a site, and sequentially stacked at a predetermined position. Then, concrete is poured into the gap between the front member and the rear member to form a tough retaining wall.

[0004] When stacking blocks in this way, the soil on the back side of the retaining wall is temporarily removed, scaffolds are assembled on the back side and the front side of the retaining wall, and workers use this scaffold to carry out construction work. Proceed.

[0005] In addition, in order to drain the groundwater accumulated on the back side of the retaining wall, it is necessary to separately form a drainage channel penetrating the block.

[0006]

However, the conventional retaining wall block is bulky because it is integrally formed with a gap between the front member and the rear member. In particular, in the case of a large block having a large gap between front and rear spaces, the block is bulky for its weight, and even a large truck can be loaded with only two or three trucks. For this reason, in the case of a large retaining wall block, it takes time and effort to carry it, and the cost becomes high. In addition, a large space is required in a factory to cure and store (stock) a bulky retaining wall block, and it is necessary to secure a large storage space (yard) at a construction site. However, it is not easy to secure a vast space in a recent factory, and it is not easy even in a construction site. In particular, it is difficult to secure a flat square in mountainous areas.

[0007] When a conventional retaining wall block is used, a large-scale scaffold is assembled on site, and scaffolding work such as disassembly after construction is complicated, and accompanying work such as construction of a drainage channel is also troublesome. .

Accordingly, the present invention provides a retaining wall block which can be efficiently transported to a site in a semi-finished state without bulk, saves storage space, and can be easily assembled and completed on site. An object of the present invention is to provide an assembling apparatus.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a right side view of the completed product after assembling the retaining wall block, FIG. 2 is a front view thereof, and FIG.
Is a plan view.

The retaining wall block 1 comprises a separately molded concrete front member 2, a rear member 3 disposed behind and spaced from the front member 2, and a rear member 3 disposed behind the front member 2 and the rear member 3. And a connecting member 4 for connecting the member 3 to the connecting member.

The front member 2 is made of a substantially cruciform thick plate-like concrete in which a rectangular convex portion is integrally formed on the upper side and the lower side of a rectangle which is oblong as viewed from the front side. Decoration part 5 protruding to imitate the shape of piled natural stone
Is formed, and a thick buried portion 6 is formed on the rear surface,
The front joint member 7 is buried in the buried portion 6 at four places toward the rear.

The front joint member 7 is a joint for connecting to a connecting member 4 described later. In this embodiment, as shown in FIG. 4, a flange 10 is fixed to one end of a metal pipe having both ends opened. Four bolt holes 11 are formed in the flange 10, and a large-diameter portion 12 is formed at an end opposite to the flange 10 as a stopper. In addition, the inside of the above-mentioned metal pipe becomes the front space 13.

When the front member 2 is molded, concrete is poured in a state where the front joint member 7 is set at a predetermined position of the formwork, and the flange 11 side of the front joint member 7 is set at a predetermined position from the rear surface of the front member 2. It protrudes backward at an inclination angle. The angle of inclination is set to an angle corresponding to the angle of inclination of the slope of the retaining wall, and extends substantially horizontally during assembly and after construction. In addition, since the inside of the metal pipe of the front joint member 7 constitutes a part of the drainage flow path as the front space 13, the concrete thickness between the front end of the metal pipe and the front surface of the front member 2 is reduced. Then, the thin portion 14 is molded in a state where it can be easily broken by a hammer or the like. Then, the broken opening serves as a drain port.

On the front side of the front member 2, a scaffold support receiving portion 15 is provided. This scaffold support receiving portion 15
Any structure may be used as long as a support (not shown) for supporting a plate material or the like serving as a scaffold used at the site can be attached. In the present embodiment, a hole opening on the front surface of the thick buried portion 6 is provided. It is constructed so that the base end of the support is inserted into this hole. In order to prevent intrusion of the concrete poured into the gap 20 of the block 1,
It is desirable that the hole be a bottomed hole that stops in the middle of the depth. In addition, it is desirable that the hole be slightly inclined downward from the opening on the surface to the back in the installed state so that the inserted support member does not accidentally come off.

The outer peripheral shape of the front member 2 may be any shape as long as it is a complementary shape that can be neatly matched or fitted with the adjacent blocks 1 in a stacked state, for example, a square or a hexagon. .

The rear member 3 is made of a substantially cruciform thick plate-like concrete like the front member 2 and has a thick buried portion 21 formed on the front surface of the substantially cruciform substrate.
The rear joint member 22 is buried in four places toward the front.

The rear joint member 22 is a joint for connecting to the connecting member 4 described later. In the present embodiment, the rear joint member 22 having the same structure as the front joint member 7 is used with its direction changed. That is, a flange 23 is fixed near one end of a metal pipe having both ends opened, and four bolt holes 24 are formed in the flange 23. Note that the inside of the metal pipe becomes the rear space 25.

When the rear member 3 is molded, concrete is poured in a state where the rear joint member 22 is set at a predetermined position of the formwork and the flange 2 of the rear joint member 22 is formed.
The four sides project forward from the front surface of the rear member 3 at a predetermined inclination angle. In addition, this inclination angle is set to an angle corresponding to the inclination angle of the retaining wall slope, and is made substantially horizontal at the time of assembly and after construction. Further, since the inside of the metal pipe of the rear joint member 22 forms a part of the drainage channel by forming the rear space 25, the concrete thickness at the rear end of the metal pipe and the rear surface of the rear member 3 is: It is molded thinner than the other parts, and the thin part 26 is molded in a state where it can be easily broken by a hammer or the like. Then, the opened portion becomes the drainage inlet.

It should be noted that the outer peripheral shape of the rear member 3 may be any shape as long as it is a complementary shape that can be neatly fitted or fitted with an adjacent block in a stacked state. Further, a scaffold support receiving portion 15 similar to the scaffold support receiving portion 15 of the front member 2 may be provided on the rear surface side of the rear member 3.

The connecting member 4 has a front end connected to the front joint member 7 and a rear end connected to the rear joint member 22. In this embodiment, as shown in FIG. The flanges 30 are fixed to each other, and four bolt holes 31 are formed in each flange 30. In addition, this metal pipe has a hollow portion 32 after construction.
Is a drain passage, and the front joint member 7
A pipe having a thickness capable of fitting the metal pipe of the rear joint member 22 therein;
The length is set in accordance with the front-rear dimension of the gap 20 formed between the first and second gaps.

The front member 2, the rear member 3, and the connecting member 4 having the above-described configurations are separately manufactured in a factory, and are loaded on a truck in a semi-finished state and transported to the site. Therefore, when loading on a truck, more can be loaded than before by, for example, stacking, and transport can be performed efficiently. These are assembled on site using a block assembly device. In addition, when curing or stocking in a factory, the front member 2, the rear member 3
Stacking can save space.

Next, the block assembling apparatus will be described. The block assembling device 35 includes a front member mounting table 36 on which the front member 2 is mounted, a rear member mounting table 37 on which the rear member 3 is mounted, and at least one of the front member mounting table 36 and the rear member mounting table 37 arranged before and after. A rail 38 that supports the front member 2 and the rear member 3 so that the front part of the connecting member 4 can be connected to the front joint member 7 by adjusting the distance between the front member 2 and the rear member 3. This device connects the rear part of the connecting member 4 to the rear member 22 to assemble and integrate the front member 2 and the rear member 3.

Specifically, as shown in FIG. 6, a long member (for example, a channel steel material) having a U-shaped cross section is provided on a frame 39.
Are fixed parallel to each other as a rail portion 38, and a front member mounting table 36 is provided at a front end portion (left end in FIG. 6) of the rail portion 38 in a fixed state, and the front member mounting table 3 is fixed.
A rear member mounting table 37 is attached to the rear of the sixth member 6 so as to be movable in the front and rear direction. The front member mounting table 36 is provided with a backrest 40 in a state where the upper end is inclined rearward, and a support member 41 is provided in a state protruding forward from the backrest 40, so that the rotation member constituting a part of the inclination angle adjusting mechanism is provided. The lower end of the backrest 40 is connected to the dynamic support shaft so that the tilt angle can be adjusted.

In the present embodiment, the front member 2 is substantially cross-shaped, so that the supporting member 41 is a shelf member on which the lower sides extending left and right of the lower protruding portion are placed, respectively, as shown in FIG. The right and left positioning of the front member 2 can be performed by fitting the protrusions into the spaces between the left and right support members 41 and 41. And, this support member 4
1 can adjust the position with respect to the backrest appropriately according to the shape, size, and the like of the front member 2, and has versatility. In addition, regarding the inclination angle adjusting mechanism, the rear member mounting table 37 is used.
, Which will be described later.

On the other hand, the rear member mounting table 37 is
The backrest 45 is attached to the slider 44 that moves along with the slider 8 and is movable in the front-rear direction together with the slider 44. The backrest 45 is provided with its upper end inclined backward, and is supported in a state of protruding forward from the backrest 45. Member 4
6, the lower end of the backrest 45 is connected to a rotation support shaft that forms a part of the tilt angle adjusting mechanism so that the tilt angle can be adjusted. The slider 44 described above may be, for example, a bogie provided with wheels 47 that roll in the U-shaped groove of the rail portion 38, or may be a sliding member.

In this embodiment, since the rear member 3 has a substantially cross shape in the present embodiment, the supporting member 46 is constituted by a member of a shelf plate on which the lower side extending to the left and right of the lower convex portion is placed. The right and left positioning of the rear member 3 can be performed by just fitting the convex portion into the space inside the.

The basic structure of the tilt angle adjusting mechanism provided on both the front member mounting table 36 and the rear member mounting table 37 may be the same, and the structure on the front member mounting table 36 side may be the frame 39 or the rail. The rear member mounting table 37 side is attached to the slider 44. Therefore, the structure of the rear member mounting table 37 will be described.

The tilt angle adjusting mechanism shown in FIG. 7A has an upper end of a telescopic shaft 49 mounted on a backrest 45 whose lower end is connected to a rotation support shaft 48, and is attached to a bearing 50 at the rear of the slider 44. The lower end of the telescopic shaft 49 is pivotally mounted, and the telescopic shaft 49 is expanded and contracted using a turnbuckle 51. Therefore, when the length of the telescopic shaft 49 is extended by rotating the turnbuckle 51, the backrest 4
5 rotates in the rising direction around the rotation support shaft 48 to decrease the inclination angle, while when the length of the telescopic shaft 49 is reduced, the backrest 45 rotates in the sleeping direction to increase the inclination angle. I do. In this embodiment, the length of the telescopic shaft 49 functioning as a support arm that supports the backrest 45 is increased or decreased by the turnbuckle 51. However, the length of the support arm may be expanded or contracted by a hydraulic cylinder. Good.

A tilt angle adjusting mechanism shown in FIG. 7B is provided with a fixing portion 53 for pivotally mounting the upper end of the support arm 52 in the middle of the backrest 45 and fixing the lower end of the support arm 52 to the slider 44 side. Are provided in the front-rear direction, and the inclination angle of the backrest 45 is adjusted by changing the fastening position. In addition, it is desirable that the inclination angle is written in each of the fastening portions 53 by a numerical value, a symbol, or the like.

In the tilt angle adjusting mechanism shown in FIG. 7C, a substantially fan-shaped worm wheel 55 is fixed to a rotation support shaft 48 connecting the lower end of the backrest 45, and a worm gear 56 is engaged with the worm wheel 55. The worm gear 56 is configured to be rotated by a drive source such as a step motor 57. Therefore, when the step motor 57 is rotated by a predetermined number of rotations, the worm wheel 55 is rotated according to the number of rotations, whereby the rotation support shaft 48 is rotated together with the backrest 45. With this configuration, the tilt angle of the backrest 45 can be electronically controlled by controlling the rotation speed of the step motor 57, and the usability is improved. It should be noted that a drive source such as a general motor may be used instead of the step motor 57, or a rotation may be manually provided by providing a handle.

In this embodiment, a ball spline 57 is fixed to the slider 44 and one end of a male screw rod 58 screwed to the ball spline 57 is connected to the step motor 5.
9 is connected to a drive source such as the drive motor 9, and the stepping motor 59 is rotated to rotate the male screw rod 58, and the rotation causes the ball spline 57 to move forward and backward. When the moving drive mechanism having such a configuration is provided, the amount of movement of the slider 44 can be controlled by controlling the number of rotations of the step motor 59, so that the operation can be easily performed. It should be noted that a drive source such as a general motor may be used instead of the step motor 59, or a configuration may be adopted in which a handle is provided and the rotary drive is performed manually.

Next, a procedure for assembling the retaining wall block 1 on site using the block assembling apparatus 35 will be described. First, as a preparation stage, the inclination angles of the backrests 40 and 45 are adjusted to the inclination (inclination angle) of the retaining wall at the site by operating the inclination angle adjusting mechanism, and the rear member mounting table 3 is adjusted.
7 is retracted from a predetermined position (a position where the front member 2 and the rear member 3 are separated by a predetermined distance). Then, the front member 2 is mounted on the support member 41 of the front member mounting table 36, and the rear member 3 is mounted on the support member 46 of the rear member mounting table 37. In this case, as described above, since the interval between the left and right support members is arranged according to the width of the convex portion of each member, when each of the members 2 and 3 is placed, the respective left and right positions are determined at predetermined positions. Also, the joint members 7, 22 of the placed front member 2 and rear member 3 have the inclination angles of the mounting tables 36, 37 in accordance with the inclination of the retaining wall, so that they extend in the horizontal direction. , Are located at the same height. When the front and rear members 2 and 3 are placed, it is desirable to use a crane or the like.

Next, the connecting member 4 is connected to one of the joint members.
One end of is fixed. For example, the rear end portion of the front joint member 7 is inserted into the opening at the front end of the connecting member 4, and is sufficiently inserted until the flanges 10 and 30 come into contact with each other so that the bolt holes 11 and 31 communicate with each other. Bolt hole 1
The nuts are tightened by passing bolts through the insides 1, 31, whereby the flanges 11, 30 are fastened to each other, that is, the front end of the connecting member 4 is fixed to the front joint member 7. In a fixed state, the connecting member 4 extends in the horizontal direction.

In this state, the rear member mounting table 37 is advanced to a position slightly before the predetermined position, the front end of the rear joint member 22 is inserted into the rear end opening of the connecting member 4, and the rear member mounting table 37 is further advanced. Then, the flange 23 of the rear joint member 22 is brought into contact with the flange 30 of the connecting member 4 so that the bolt holes 24 and 31 communicate with each other. Then, a nut is tightened by passing a bolt into the communicating bolt holes 24, 31, thereby tightening the flanges 24, 30, that is, fixing the front end of the rear joint member 22 to the rear end of the connecting member 4. Since the connecting member 4 and the rear joint member 22 extend in the horizontal direction and are located at the same height, the front end portion of the rear joint member 22 fits smoothly into the rear end opening of the connecting member 4. I do.

When the front member 2 and the rear member 3 are connected and integrated by the connecting member 4 in this manner, a gap 20 having a predetermined size is formed between the front and rear members 2 and 3. In addition, the rear space 25 of the rear joint member 22, the hollow portion 32 of the connecting member 4, and the front space 13 of the front joint member 7 are communicated in series. Therefore, when this communicating empty portion is used as a drain passage for draining water on the back side of the rear member 3 to the front surface of the front member 2, the thin portion 14 in front of the front joint member 7 and the rear joint The thin portions 26 behind the member 22 are broken down and opened, respectively,
It penetrates from the rear surface of the rear member 3 to the front surface of the front member 2.

After assembling the retaining wall block 1 in this manner, the integrated block 1 is removed from the assembling apparatus 35 using a crane or the like, and installed at a predetermined position on the construction site. For example, the first-stage blocks 1 are arranged side by side on a pre-constructed foundation, and the first-stage blocks 1.
The second blocks 1 are stacked on top, and then sequentially stacked. When the integrated block 1 is hung by a crane, a wire rope or the like can be hung on the connecting member 4, so that workability is good.

When stacking the blocks 1 or placing concrete in the gaps 20 of the blocks 1, the worker moves on the scaffold.
By simply attaching the base end of the scaffolding support to the scaffolding support receiving portion 15 of the above, the scaffolding plate can be easily bridged between the scaffolding support brackets. Also, when scaffolding is constructed behind the retaining wall, much less earth and sand must be removed. Therefore, unlike the case where the conventional retaining wall blocks are stacked, the use of the retaining wall block 1 according to the present invention makes it possible to extremely easily assemble and disassemble the scaffold, and furthermore, according to the number of stacked stages. Since a scaffold can be formed, workability is good.

When the retaining wall is constructed in this way, the back side of the retaining wall is filled with stones and backfilled with earth and sand, but a water permeable material may be added to the rear surface of the blocks 1. For example, a water-permeable expanded polystyrene plate 60 formed by attaching foamed polystyrene particles while securing a small gap to form a plate-like body may be provided. In order to attach the expanded polystyrene plate to the retaining wall block 1, a protrusion may be previously projected from the rear surface of the rear member 3 and may be hooked on the protrusion.
It may be adhered by an adhesive. Further, when the rear member 3 is molded, the rear member 3 may be adhered before curing of the poured concrete is completed, and fixed by hardening the concrete. When such a water-permeable material is used, the amount of stuffing of stones is reduced, or it is not necessary to stuff stones, so that labor can be saved.

In the above-described embodiment, the connection between the front and rear joint members 7, 22 and the connecting member 4 is made by connecting the flanges with bolts and nuts. However, the connection structure between the joint member and the connecting member 4 in the present invention is not limited to this, and the design can be changed as appropriate. For example, the joint member and the connecting member 4 may be formed of a pipe material, a screw may be formed at a portion to be connected, and the screw may be screw-connected. In addition, the front member mounting table 36 and the rear member mounting table 37 may be provided with separate tilt angle adjusting mechanisms so that the angles can be adjusted separately, or only one of them may be provided with the tilt angle adjusting mechanism. Good.

Are integrated , so that they can be manufactured separately at the factory and transported to the site in a semi-finished state, and can be assembled at the site and completed as an integrated block. Therefore, even if it is a large retaining wall block, it does not become bulky before being integrated,
Even if trucks of the same size are used, they can be transported efficiently. For this reason, it is possible to reduce the labor of transportation as compared with the conventional block of the same size. Further, since this block is not bulky before being integrated, a curing space and a subsequent storage space can be remarkably saved in a factory. At the construction site, only the required number may be assembled for the time being according to the progress of the work, so that the storage space for the finished product can be greatly reduced.

Further, since the vacant space communicated in series is used as a drainage channel for draining water on the back side of the rear member to the front surface of the front member, the connecting member has a drainage function in addition to its original function as a connecting member. It also has a function as a flow path for use. Therefore, it is possible to save the trouble of separately forming the drain passage, and it is possible to improve the work efficiency.

According to the second aspect of the present invention, since the scaffold support receiving portion is provided on the block itself, the scaffold can be secured by a simple operation, and can be easily removed after construction. Therefore, the trouble of assembling and disassembling the tower for scaffolding separately can be saved. Also, when scaffolding is constructed behind the retaining wall, much less earth and sand must be removed. Therefore, unlike the conventional case in which the retaining wall blocks are stacked, the use of the retaining wall block according to the present invention makes it possible to extremely easily assemble and disassemble the scaffold, and furthermore, the scaffold according to the number of stacked stages. Therefore, the workability is good.

According to the third aspect of the present invention, the front member mounting table, the rear member mounting table, and the rail portion for supporting at least one of the mounting tables arranged in the front and rear directions so as to be movable in the front and rear direction are provided. By adjusting the distance between the member and the rear member, the front part of the connecting member can be easily connected to the front joint member, and the rear part of the connecting member can be easily connected to the rear joint member. Therefore, the assembling work between the front member and the rear member made of heavy concrete can be easily performed for the weight. Further, the dimension of the gap between the front member and the rear member can be made constant. Therefore, even if the blocks are field-assembled, the dimensional error when they are stacked can be reduced.

According to the fourth aspect of the present invention, since the tilt angle adjusting mechanism for adjusting the tilt angle of at least one of the front member mounting table and the rear member mounting table is provided, the front member and the rear member are adapted to the inclination of the retaining wall. They can be connected and integrated in a state of inclination at an inclination angle. Therefore, the connection work between the joint member and the connection member can be performed smoothly. Further, the inclination angle of the assembled block can be accurately and easily adjusted to the inclination as designed.
