Description

[Detailed description of the invention] [Industrial field of application] This invention relates to the support of wall plates in soundproof walls, etc., and is particularly suitable for use in places where workability is poor, such as railway viaducts or road viaducts, and even when trains, etc. are passing. The present invention relates to a wall plate support suitable for soundproof walls subjected to wind pressure and vehicle protection walls on roads.

[Prior Art] Conventionally, for example, on railway viaducts or road viaducts, soundproof walls have been provided to block noise, and vehicle protection walls have been installed on the cliff sides of roads to prevent vehicles from falling due to misoperation. provided.

As a support for a wall board, for example, as disclosed in Utility Model Application Publication No. 27976 of 1920, a metal support is fixed to the foundation with a fastening means, and a plurality of support blocks having vertical grooves are attached to the metal support. There are some that can be inserted through to complete the wall board support.

This is a support for a mixed earth wall, and requires work to position and fix it to the foundation of the metal support, and work to insert the support blocks into the metal support in order to attach the wall board.

Therefore, when using it as a support for a soundproof wall, especially in places where work efficiency is poor, such as railway viaducts or road viaducts, and where nighttime work hours are restricted, the work time will be longer, making it difficult to use it. Can not. Further, it cannot be used, for example, as a support for a soundproof wall on a railway, which is subject to wind pressure or vibration when a vehicle passes by, or for a support for a vehicle protection wall that prevents vehicles from falling due to operational errors.

For this reason, for soundproof walls, etc., plated H-steel columns are generally fixed to the side walls of the viaduct with bolts or other tightening means, and soundproof wall plates are attached to the column surfaces arranged at equal intervals in this way. A separately formed fixing member is tightened and fixed to the H steel column, and the soundproof wall board is held to the column by this fixing member.

[Problem that the invention aims to solve] By the way, this support is made of plated H-steel product and is coated with anti-rust coating, but the coating will wear off after several years, so it is necessary to repaint it periodically. Scaffolding must be erected in order to apply this coating, which costs a considerable amount of money. For this reason, for example, as disclosed in Japanese Utility Model Application Publication No. 54-177114, a cement layer containing alkali-resistant glass fibers is coated, but since it is similarly coated, it may peel off. The shape and size of the fitting groove formed in the support column are limited by the H-shaped steel.

In addition, the columns are installed in the concrete walls of the side walls of the viaduct, but this method uses bolts that are screwed into iron joints that reinforce the concrete. , it takes a lot of effort to fix the pillars.

Furthermore, the soundproof wall board has a separately formed fixing means.
Because it was fixed to a steel column and held by the column, there were problems such as poor work efficiency.

This idea was made against this background, and the main body of the pillar was made of concrete.
It completely eliminates the need for painting, eliminates maintenance costs, reduces production costs, and shortens construction time.Moreover, the installation of the support can be completed by simply hoisting the main support, inserting it into the structure, and burying it. A wall board for soundproof walls, etc. that can be firmly fixed to a structure in a short time, and the wall board fits and is held in the main body of the support, making it easy to work even in places where scaffolding is difficult to assemble. The purpose is to provide a support for

[Means for Solving the Problems] In order to solve the above problems, this invention arranges steel materials such as reinforcing bars or steel pipes as a core member along the entire axial length of a support main body made of concrete,
A fitting groove in which the wall plate is fitted and held in the axial direction is formed in the concrete portion of the column main body, and the core member is extended in the axial direction from one end of the column main body to form an insertion portion. The insertion part is inserted into the structure with the end of the support main body in contact with the structure and is fixed to the structure, and the other end of the support main body is provided with a removable lifting fitting.

[Function] In this invention, a lifting fitting is attached to one end of the concrete column body, the concrete is lifted up by a crane or the like through a rope, and the insertion portion of the core member extending from the other end of the column body is inserted into the structure. By this insertion, the end of the support main body comes into contact with the structure to perform positioning, and in this state, the insertion part is fixed and integrated with the structure.

[Example] Hereinafter, an example of this invention will be described in detail based on the accompanying drawings.

FIG. 1 is a perspective view showing a wall plate support in a soundproof wall or the like according to this invention.

2 to 5 show an embodiment in which the above-mentioned support according to this invention is used for a soundproof wall of a railway viaduct, FIG. 2 is a front view, and FIG. 3 is a -
FIG. 4 is a cross-sectional view taken along the side of FIG. 2, and FIG. 5 is a cross-sectional view taken along the side of FIG.

The column main body 1 is made of concrete with reinforcing bars as core members 2, 3, and 4, and has fitting grooves 5 on a pair of opposing side surfaces of the concrete portion in which a soundproof wall is fitted and held in the axial direction. . The core member 2 is made of thick reinforcing steel, and two core members 2 are disposed in the center of the column main body 1 and on a line connecting both fitting grooves 5 along the entire length of the column main body 1 in the axial direction.

One end of each core member 2 is
An insertion part 2a extends downward from the concrete part in the axial direction and is inserted into and fixed to a structure, and the end of this support main body 1 serves as a positioning means that comes into contact with the structure. The core members 3 and 4 are made of reinforcing steel that is thinner than the core member 2, and the core member 3 is arranged in the axial direction, and these are reinforced by connecting the core members 4 at four equally spaced positions by assembling them in parallel grids. ing. A female threaded bolt 6 is buried in the upper part of the support main body 1, and a lifting fitting 7 can be screwed into this.

The core member 2 in this embodiment is arranged on a line connecting the fitting grooves 5 of both soundproof wall plates, that is, in a direction parallel to the soundproof wall plates to be described later, but on the side surface on the side where the fitting groove 5 is not formed, i.e. By arranging it perpendicularly to the soundproof wall board, the strength against wind pressure is further improved, and the support main body 1 can be made smaller.

Further, the number of core members 2 is not limited to two, and may be more than two or one, and can be appropriately selected in consideration of the strength, the insertion position of the insertion part 2a into the structure, etc. Further, in this embodiment, the core member 2 is made of a thick reinforcing bar, but a single large steel pipe may be used, and a steel material of an appropriate shape may also be used.

Although the core members 4 in this embodiment are provided at four equally spaced locations on the core member 3, the present invention is not limited to this, and portions where strength is required may be provided closely together. Of course, if the strength is not so required, the core member 3 or 4 may not be used.

In addition, the fitting groove 5 of the soundproof wall board in this embodiment
In order to facilitate fitting of the soundproof wall board, a radius 5a is attached to the opening end, but it can also be a sloped surface, and furthermore, it can be integrally formed into any shape and size depending on the shape of the soundproof wall. Ru.

The support main body 1 is used as a support for a soundproof wall plate 10 in a soundproof wall 9 of an existing railway viaduct 8 or the like. Concrete walls 8 on both sides of this railway viaduct 8
A is flattened by applying adjustment mortar 11 on its upper surface. An insertion hole 12 into which the insertion portion 2a of the column main body 1 is inserted is bored in the concrete wall 8a at a position away from the reinforcing reinforcing bars 13 of the concrete wall 8a. Then, add 14 resin mortar to this.
Fill it with. Next, the lifting fitting 7 is screwed onto the female threaded bolt 6 of the support main body 1, lifted by a crane or the like, and the insertion part 2a is inserted into the insertion hole 12. At this time, the end of the column body 1 comes into contact with the structure to determine the position of the insertion, and in this state the column body 1 is fixed to the concrete wall 8a to form an integral structure.

In this way, the support main body 1 can be fixed to the concrete wall 8a of the viaduct 8 by simply inserting the insertion part 2a into the insertion hole 12 of the concrete wall 8a, making the assembly work extremely simple.

In addition, the insertion part 2a is integrally fixed to the concrete wall 8a by the resin mortar 14, making it an integrated structure that is even stronger, and the support main body 1 is firmly fixed, and can withstand wind pressure, vibration, and impact for one minute. It becomes a structure.

In addition, when installing soundproof walls on a newly constructed viaduct,
When forming a concrete wall of a viaduct, the insertion part 2a of the support main body 1 is integrally fixed at the same time as the concrete wall 8a without drilling an insertion hole. In this way, the soundproof wall board 10 is installed in each of the assembled pillar bodies 1. Both ends of the soundproof wall board 10 are fitted and held in the fitting grooves 5 of the column main body 1 via hard rubber packings 15, etc., to suppress rattling when a train passes.

In addition, hard rubber gaskets 16 and 17 are interposed between the soundproof wall board 10 and the adjustment mortar of the viaduct 8 and between both soundproof wall boards 10 to suppress rattling.
We take care not to cause noise or damage.

The soundproof wall board 10 is made of concrete with a reinforcing bar as a core member, and has a hollow section 18 in the lateral direction, but is not limited thereto, and various well-known soundproof wall boards can be used.

The pillar according to this invention can be widely applied to soundproof walls other than railways, roads, and elevated bridges, and even to handrails and the like.

[Effects of the invention] As mentioned above, this invention has steel materials such as reinforcing bars or steel pipes arranged as a core member along the entire axial length of the pillar body made of concrete, so that the pillar body made of concrete is strong. Moreover, since the fitting groove in which the wall plate is fitted and held in the axial direction is formed in the concrete portion of the support main body, the fitting groove can be easily formed in any shape.

Furthermore, the core member extends in the axial direction from one end of the column main body to form an insertion part, and this insertion part is inserted into the structure with the end of the column main body in contact with the structure, and is fixed integrally with the structure. The other end of the main body is equipped with a removable lifting metal fitting, so simply inserting the insertion part of the core member extending from the other end of the concrete support main body into the structure and fixing it will complete the tightening method. To complete the installation of wallboard supports on a soundproof wall or the like of a certain height without the need for any other equipment. It is particularly suitable for use as supports for soundproof walls in places where workability is poor, such as railway viaducts or road viaducts, and where work hours are restricted at night.

In addition, the main body of the pillar is inserted into a predetermined position of a structure such as a viaduct, and is integrated with the structure and firmly fixed, compared to conventional methods that are fixed by tightening and fixing means such as bolts. , the installation of the support column becomes even stronger. Therefore, it can be used, for example, as a support for a soundproof wall on a railway to withstand wind pressure and vibrations when a train passes by, and can also be used as a support for a protective wall to prevent falling due to vehicle operation errors.

In addition, since the main body of the support is made of concrete, there is no need to apply anti-rust coating as with conventional H-steel structures, and maintenance costs are reduced. Moreover, since it is made of concrete, the manufacturing cost is lower than that of H steel, and the construction period is also shortened.

In addition, since the wall plate is installed by fitting into the fitting groove formed in the main body of the support, it is compared to the conventional one which is formed separately from H steel and is held by tightening and fixing the fixing member. It is easy to assemble, and the number of parts is reduced, resulting in cost reduction.

In addition, the fitting groove of the column main body is easily formed as it is integrally formed when the column main body is molded, and it is also possible to appropriately form a radius or an inclined surface to facilitate fitting of the wall plate. It is also easy to have a shape that corresponds to the shape of.
