JP6969954B2 - Mounting bracket for lightweight embankment panel and mounting structure using it - Google Patents

Description

The present invention relates to a mounting bracket for a lightweight embankment panel used for roadbed construction and a mounting structure using the same.

Conventionally, the lightweight embankment method has been used for roadbed construction and widening of roads in soft ground and steep slopes. In the lightweight embankment method, the wall surface of the roadbed is constructed with lightweight embankment panels, and styrofoam blocks are piled up with the ground, etc., or bubble mortar concrete (hereinafter, simply referred to as "bubble mortar") is placed to build the roadbed. I'm building. These Styrofoam blocks and bubble mortar serve as embankments for the roadbed.

In the structure where Styrofoam blocks are stacked, no load directly acts on the panel for lightweight embankment, but in the construction method using bubble mortar, the load must be withstood until the placed bubble mortar hardens, so it is for lightweight embankment. The panel and mounting bracket are required to have the strength to withstand the load.

As a prior art of this kind, for example, an extruded cement board is used as a panel forming a wall surface for embankment, and the extruded cement boards are connected to each other by connecting members provided in the hollow portions of the upper and lower extruded cement boards. Some connecting members are supported by an anchor portion embedded inside the embankment (see, for example, Patent Document 1).

Further, in order to eliminate restrictions on the work place and on-site processing due to construction efficiency, a mounting structure in which metal fittings are embedded in the panel in advance and which does not require drilling may be used. For example, as this kind of prior art, a connecting tool is embedded in advance inside the formwork panel for wall construction, and the connecting tool provided on the upper side of the lower formwork panel and the lower side of the upper formwork panel. There is a device that engages a connecting member with a provided connecting tool. Then, the connecting fixture to which the connecting member is fixed is fixed to the support column erected on the ground side so that the formwork panels are stacked (see, for example, Patent Document 2).

However, in Patent Document 1, a connecting member having a size matching the shape of the hollow portion of the extruded cement plate is required, and the strength of the metal fitting that connects the connecting member and the engaging portion is also required, so that the cost of the metal fitting is high. Up. Further, since the extruded cement plate is held only by the hollow portion, the surface accuracy on the outer surface side of the wall surface may not be obtained depending on the accuracy of the hollow portion and the metal fittings. The surface accuracy refers to the accuracy of entering and exiting the outer surface side between the upper, lower, left and right panels.

Further, in Patent Document 2, since it is necessary to embed a connecting tool on the back surface in advance and pour concrete into the formwork panel at the time of manufacturing, the manufacturing efficiency is poor and cost and time are required. Further, since the connecting tool is embedded in advance, the position of the connecting tool is limited, and the mounting position of the formwork panel is restricted. Further, when the formwork panel is cut to adjust the width and length, there are construction restrictions such as difficulty in mounting.

Further, in any of the prior arts, for example, when it is necessary to adjust the surface accuracy on the surface side of the wall surface, it is necessary to position the upper and lower panels via adjusting bolts, spacers, etc., which requires labor and time. .. Moreover, if it is necessary to adjust between the left and right boards and the entire wall surface, further labor and time are required for the construction.

Therefore, it is an object of the present invention to provide a mounting bracket for a lightweight embankment panel that has good construction efficiency and does not require adjustment of the entry / exit of the lightweight embankment panel that is stacked in the vertical direction, and a mounting structure using the same.

It can be appropriately performed only by the adjustment and the adjustment of the entire surface of the wall surface 5. Moreover, this adjustment work may be adjusted by the adjusting nut 85 on the support column 80 side of the separate bolt 60, and the workability can be improved.

Further, as shown in FIG. 7, a plate-to-plate sealing material 36 (vertical joint tape) is attached to the back surface side of the vertical joint portion 7 of the lightweight embankment panel 30 arranged on the left and right sides. This makes it possible to prevent the outflow of water and the like after construction. Even when the lightweight embankment is a styrofoam block, it is preferable to provide an inter-plate packing material 35 and an inter-plate sealing material 36 between the upper and lower lightweight embankment panels 30 to prevent the outflow of water and the like after construction. ..

Further, by connecting the horizontal joints 6 to each other with the concave engaging portions 32, even if the bubble mortar 70 flows out to some extent, it is retained in the concave engaging portion 32 and prevented from flowing out to the outside of the lightweight embankment panel 30. Can be done. As a result, the eflo essence of the bubble mortar 70 and water are less likely to flow to the outside, so that it is possible to prevent the wall surface 5 formed on the outer surface of the lightweight embankment panel 30 from being contaminated based on these factors.

On the other hand, as shown in FIG. 6, in the upper part of the mounting structure 1 of the lightweight embankment panel 30, the lower engaging portion 51 of the end mounting bracket 50 is engaged with the concave engaging portion 32 of the upper part of the lightweight embankment panel 30. Will be combined. The end mounting bracket 50 is fixed to the upper inner surface of the lightweight embankment panel 30 by screwing the holding bolt 41 into the holding bolt hole 15 of the connecting tool holding portion 13. Similar to the lower part of FIG. 5, the end mounting bracket 50 also has a fixing nut 62 (FIG. 5) in which the L-shaped tip portion 61 of the separate bolt 60 is engaged with the ring-shaped portion 41a of the holding bolt 41. It is fixed in 7). The other end of the separate bolt 60 extends in the direction of the support column 80, is inserted into the through hole 84 of the high nut 83, and is fastened by the adjusting nut 85. The separate bolt 60 is fixed from above and below by a bolt 83a provided on the high nut 83. The mounting structure with the upper end mounting bracket 50 is the same as the mounting structure with the lower end mounting bracket 50 shown in FIG. 5 in the vertical direction. Further, the left-right direction is the same as that in FIG. 7, and detailed description thereof will be omitted.

(Summary)
As described above, by using the first mounting bracket 10 and the second mounting bracket 20, the lightweight embankment panel 30 to be stacked in the vertical direction can be appropriately stacked without adjusting the surface entry / exit, and the upper and lower panels can be stacked appropriately. It is also possible to improve the surface accuracy of the wall surface 5 formed by the lightweight embankment panel 30. Therefore, in the construction of the lightweight embankment panel 30, it is only necessary to perform the entry / exit between the left and right lightweight embankment panels 30 and the entry / exit adjustment of the entire wall surface, so that the work efficiency of the lightweight embankment method can be improved.

Further, since the processing for attaching the mounting brackets 10 and 20 to the lightweight embankment panel 30 is not required, there is no need to process the panel on site, and the concave engaging portion 32 extending the mounting brackets 10 and 20 in the lateral direction. Since it can be attached to any position, it is possible to improve workability in this respect as well.

Further, by using the lightweight embankment panel 30 as an extruded cement plate, the lightweight embankment panel 30 having the concave engaging portion 32 formed can be easily manufactured. Moreover, by connecting the concave engaging portions 32 of the lightweight embankment panel 30 with the mounting brackets 10 and 20, for example, even if the bubble mortar 70 flows out to the horizontal joint portion 6 to some extent, it is contained in the concave engaging portion 32. It is possible to prevent it from staying and flowing out to the outer surface of the lightweight embankment panel 30. As a result, the eflo essence and water of the bubble mortar 70 are less likely to flow to the outer surface of the lightweight embankment panel 30, and the wall surface 5 formed by the lightweight embankment panel 30 can be prevented from becoming dirty.

Further, in the above embodiment, since the mounting brackets 10 and 20 can be manufactured by processing one metal plate material 16 and 26, the required strength after mounting on the horizontal joint portion 6 of the lightweight embankment panel 30 can be obtained. It is easy to secure, and durability can be improved by integral molding.

(Modification example)
The lightweight embankment panel 30 may be any as long as it can form a lightweight aerated concrete plate and a concave engaging portion 32 in addition to an extruded cement plate, and other materials such as a PC plate can also be used and are lightweight. The embankment panel 30 is not limited to the above-described embodiment.

Further, when an extruded cement plate is used as the lightweight embankment panel 30, for example, even when the length in the vertical direction is adjusted, the shape is about the same as that of the concave engaging portion 32 (for example, cut by the hollow portion 31). If a predetermined plate thickness) remains inside, it can be held by the mounting brackets 10 and 20. Therefore, the lightweight embankment panels 30 can be stacked without any special processing.

Further, the shape of the concave engaging portion 32 described above is not limited to the above embodiment, and any shape other than the above-described embodiment can be implemented as long as the mounting brackets 10 and 20 can be engaged and held in place. It is possible to change various configurations without impairing the gist of the present invention, and the present invention is not limited to the above-described embodiment.
