Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of exterior materials which are attached to structures such as viaducts and elevated roads or buildings such as buildings.

[0002]

2. Description of the Related Art At present, various types of exterior materials are known. For example, in a structure such as a viaduct, it is not preferable that the rainwater that has fallen on the viaduct falls down as it is. In order to guide the water to the ground, a drain pipe is laid as an exterior material on the outer wall of the pier. Such a drain pipe is generally made of fiber reinforced plastic (Fiber Reinf) in consideration of durability.
Ordinary plastics (hereinafter referred to as “FRP”) is often used for mounting.

[0003]

However, since the FRP itself has a color close to milky white, when it is applied to a structure or the like as a drain pipe as it is, the color of the outer wall of the structure or the like and the color of the drain pipe are different. However, there is a problem that it is too different to cause a sense of incongruity. Therefore, it is conceivable to apply the same paint as the outer wall after the construction, but FRP has a problem that the paint is peeled off in a short period of time due to poor paint applicability, making it difficult to see. For this reason, conventionally, a drainage pipe made of FRP filled with a pigment of a color similar to the outer wall surface has been used. However, even if the colorant (pigment) is filled in this way, it is difficult to match the color of the drain pipe with the color of the outer wall. There is a problem that physical properties deteriorate. Further, in the case of a bridge pier, a groove may be formed on the outer wall surface, and a drain pipe may be fitted into the groove so that the drain pipe does not protrude from the outer wall surface. Also, if there is no gap in the outer wall of the drainage pipe, or if it is to be applied in a small place, for example, to waterproof coating to a height of about 1 m from the ground, the exposed surface of the drainage pipe is left as it is. If they are applied together, the coating on the exposed surface will be peeled off at an early stage, which is not only unsightly, but also results in impairment of waterproofness at the peeled portion. In order to avoid this, it is necessary to apply a waterproof coating to the inside of the groove with no drainage pipe on the painted part, especially when repainting the outer wall, it is necessary to remove and install the drainage pipe. Not only does the work become cumbersome and complicated, but also the drainage pipe itself is not painted, so that this portion is left in an unusual state and in an old state. Furthermore, the conventional one has poor fire resistance because the drainpipe is directly exposed.For example, if there is a bonfire nearby, there is a problem that the fire spreads and burns easily. There are problems to be solved by the invention.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve these problems in view of the above-mentioned circumstances, and a building structure has an outer surface exposed to the outside. In the exterior material made of fiber reinforced plastics attached and constructed as described above, the exposed outer surface is subjected to a surface treatment so that a part of the concrete aggregate is buried. It is an exterior material of a product. By doing so, the exterior surface exposed to the outside is a surface treatment of the concrete aggregate, although it is an exterior material formed of fiber reinforced plastic, and as a result, the building structure is not filled with any pigment. It is possible to make the color similar to the concrete surface color of the object and it will not be uncomfortable, but it will also improve fire resistance, weather resistance, etc., and will have excellent durability, paintability and mortar Is also improved, so that the surface can be easily treated. In this case, the concrete aggregate to be surface-treated can be characterized in that a color that substantially matches the outer surface color of the building structure is selected. about,
The surface color corresponding to the surface color of the building structure can be easily obtained. In these things, it can be characterized that paint is applied to the exposed surface of the exterior material,
In this case, the same paint as that applied to the building structure can be applied, and the sense of unity is improved. In the above, the mortar may be applied to the exposed surface of the exterior material, and in such a case, the surface of the building structure is mortar-treated together with the outer surface of the exterior material. This improves the sense of unity and makes it more durable. In these, the exterior material can be characterized by being a drain pipe attached to the pier and constructed.
The exposed outer surface of the drainpipe is excellent in durability, and can be made to have a color that is not strange to the surface of the pier surface.

Next, embodiments of the present invention will be described with reference to the drawings. In the drawing, 1 is a bridge on an elevated highway, 2 is a pier supporting the bridge 1, and a drainage basin 3 is buried at a position corresponding to the pier 2 of the bridge 1. The main body 3a of the drainage basin 3 is made of FRP using epoxy resin as a matrix material and glass fiber as a reinforcing material, and is much lighter than a conventional metallic one. On the outer peripheral surface of the drainage basin main body 3a, a concrete aggregate to be filled in the concrete is attached so as to partially bury the concrete.
In other words, in forming the drainage basin main body 3a, before the resin layer on the outer surface is hardened, the whole surface of the resin layer on the outer surface is coated with concrete aggregate, such as gravel or pebble having a diameter of about 1 to 3 mm, or sand. Is sprayed on one surface, whereby a part of the aggregate is buried in the surface of the resin layer. And the drainage basin body 3a whose outer surface is thus treated with aggregate.
Into the mounting hole opened in the frame so that the upper edge of the opening is slightly lower than the road surface, and fill the gap with mortar or concrete and fix it. Drainage basin body 3 made of FRP because it will adhere well to
Although it is a, it is ensured that it is firmly fixed to the skeleton side and that peeling does not occur. In the figure,
Reference numeral 4 denotes a grating incorporated in the upper opening of the drainage basin main body 3a. Reference numeral 3b denotes a gutter tube fixed to the drain port of the drainage basin 3, 3c denotes a bellows-like connecting and contracting connecting gutter connecting the gutter tube 3b and a drain pipe 5 described later, and 3d denotes a gutter tube 3b. Cover.

On the other hand, the pier 2 has a groove 2 on its side.
a is formed, and the drain pipe 5 embodying the present invention is formed in the concave groove 2a.
Are installed in a loose fit manner. The drain pipe 5 has an elongated main body 5a having a hat-shaped cross section comprising a left groove portion 5b and left and right plate portions 5c extending in the width direction from both ends of the opening. A flat plate-like lid 5d which is set to have the same width as the outer edge of the portion 5c and covers the opening of the concave groove portion 5b, and both left and right plate-like portions 5c and both ends in the width direction of the lid 5d. Are formed integrally by appropriate fixing means such as adhesion, adhesion, fusion, welding, etc.,
Thereby, it is comprised as a cylindrical thing with the left and right flange parts 5e. In addition, the concave groove 5b is widened (increased) in the left-right width direction and the depth (bottom) direction by an appropriate length A in the length direction at the one end (upper end in the case of construction), and by the thickness of the plate. A wide portion 5g is formed via a step 5f. On the other hand, the lid 5d and the flange 5e on the other end (the lower end when applied) are set to be shorter than the main body 5a by a length B (A> B) slightly smaller than the length A. Have been. Further, at the other end of the main body 5a, a closing plate 5h for closing the opening end of the concave groove portion 5b to the other end of the main body is integrally formed in a state of overlapping the inner surface of the lid 5d by the length C. The inner surface of the lid 5d and the surface of the closing plate 5h are fixed by the same fixing means as described above.

[0007] Then, one end and the other end of the vertically adjacent drain pipe 5 are connected and attached. In this case, the other end (lower end) of the upper drain pipe 5 is moved downward. The inner drain pipe 5 is internally fitted and connected to a wide portion 5f which is one end (upper end). In this connection, as for the concave groove portion 5b, the wide portion 5f on the upper end side is wider by the thickness of the concave groove portion 5b, and the length A of the wide portion 5f is the same as that of the flange portion 5e on the other end side. As a result of the setting slightly shorter than the length B without the lid 5d, consideration is made that the fitting can be performed in a state where the other end edge of the concave groove 5b does not abut the step 5f. Even if there is some processing error in the longitudinal direction, the flange 5e and the lid 5d can be connected without any gap where the upper and lower edges of the lid abut. Further, in this connecting portion, a blocking plate 5h is provided in the concave groove portion 5b in a portion where the lid 5d is not provided, so that the connecting portion is fitted to the inner surface of the lid 5d of the wide portion 5g. The lower end of the upper drain pipe 5 is fitted inside the upper end of the lower drain pipe 5 so as to prevent water flowing down the drain pipe 5 from leaking out. . In the present embodiment, the main body 5 of the drain pipe 5
a and the lid 5d are made of the same material as the drainage basin main body 3a, and the outer surface of the lid 5d (the same as the outer surface of the flange portion 5e) is applied to the outer surface of the drainage basin main body 3a. The same surface treatment as that performed, that is, at a stage before the resin layer is cured, the concrete aggregate 1 to 1 on the entire surface of the resin layer on the surface.
Gravel X having a diameter of 3 mm is sprayed on one surface, whereby a part of the aggregate is set to be embedded in the surface of the resin layer.

In the embodiment of the present invention configured as described above, the drain pipe 5 is formed with a suitable space in the vertical direction with the packing 6 interposed between the flange portion 5e and the pier 2. In this case, the anchor bolt 7 is used to attach and attach the mounting hole 5i. In this case, the outer surface of the flange portion 5e exposed to the outside as the outer surface even after the attaching and attaching is provided with concrete bone. Gravel X as a material
The drainage pipe 5 is exposed to the outside as a result of the surface treatment in which a part of the aggregate is buried in the surface of the resin layer. As an aggregate, it becomes a color similar to the outer surface of the pier 2 formed of concrete,
It can be something that does not feel strange. In addition, since the surface treatment does not require coloring by filling the matrix material with a pigment, the predetermined strength can be maintained without impairing the physical properties of the matrix material.
In addition, since the exposed outer surface of the drain pipe 5 is covered with a highly invariant concrete aggregate made of an inorganic substance, various properties such as weather resistance, corrosion resistance, and fire resistance are obtained. And the durability is improved.

In this case, mortar spraying may be performed for the purpose of smoothing the surface of the pier 2 or the like. In such a case, the mortar spraying may be performed on the exposed surface of the drain pipe 5 as it is. In this case, the sprayed mortar adheres firmly to the surface-treated concrete aggregate on the exposed surface and does not peel off in a short period of time, and as a result, The surface of the drain pipe 5 itself may be mortar-processed together with the surface of the pier 2 to make it completely inconspicuous. In this case, the drainage pipe 5 can be further reinforced, weather resistance, fire resistance and the like are remarkably improved, so that the durability is further improved and the aesthetic appearance can be secured.

The pier 2 may be coated to a height of about 2 m from the ground for the purpose of water resistance or the like. In such a case, it is assumed that the surface of the drain pipe 5 is exposed. As described above, since the exposed surface is subjected to the treatment of adhering the concrete aggregate having a good coating property, the peeling of the paint can be prevented at an early stage, and the appearance can be secured.

In this case, the adjacent drain pipes 5 are connected so that the lower end of the upper drain pipe 5 is entirely fitted in the wide portion 5f serving as the upper end of the lower drain pipe as described above. Although the flowing water does not leak out of the connecting portion because of the configuration for assembling, the wide portion 5f
The closing plate 5h closes the opening surface side of the concave groove, but since the closing plate 5h is configured to be recessed by the plate thickness of the cover 5d, the lids 5d including the flange portion 5e are connected to each other. Is flat, and the step portion 5g is not required unlike the case where the wide portion 5f is formed, and the appearance is excellent.

It should be noted that the present invention is not limited to the above-described embodiment, and the exterior material may be implemented as long as the building structure has an outer surface exposed to the outside. Can be. In this case, when the building structure is colored, a concrete aggregate having a color close to the colored color may be subjected to the surface treatment. Such colored aggregates can be obtained efficiently by crushing stones colored in the corresponding color.
