Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wall balustrade rubber cover that covers a play gap of a wall balustrade portion that occurs at a joint portion of a highway.

[0002]

[Prior art and problems]

 The joints of highways are joined by finger joints etc. to absorb the expansion and contraction of road surface components due to changes in temperature, but as shown in Fig. 6, there is a gap (B) between the end faces of the wall balustrade. For safety reasons, this clearance (B) must be closed by some means for safety.

Conventionally, a method that is often used is a method in which the play gap (B) as shown in FIG. 7 is closed with a pair of steel plates (3) and (3). This is a method that is often used because the materials are relatively easy to obtain and can be used for sudden construction. In this case, one end of each steel plate (3) is fixed by bolts (17) and nuts (22) to the road side surface near the end (A) of each wall balustrade, and the other end is a free end ( 31).

The free space (B) is covered with both of the steel plates (3) and (3) where the free ends (31) and (31) are superposed. In this block system using steel plates, when the free space (B) between the ends of the wall balustrade expands and contracts, the free ends (31) and (31) of the steel plates (3) and (3) remain overlapped. 3) (3) slides against each other, and the clearance (B) can always be closed regardless of the expansion and contraction of the clearance (B).

However, in the blockage method using the steel plate (3), when displacement in the vertical and horizontal directions occurs in the clearance (B) during ground subsidence, the elastic deformability is poor and the expansion and contraction of the clearance can be followed. There is a concern that the steel plate (3), etc. may be damaged. In view of the above point, the present invention can absorb any displacement of the clearance in the "rubber cover for wall balustrade that covers the clearance generated in the wall balustrade of the expansion joint of the expressway", and can be easily installed. The task is to do so.

[0006]

[Technical means]

 The technical means of the present invention for solving the above-mentioned problem is that "the entire cover is formed of an elastic material such as rubber with a groove member having a substantially U-shaped cross section, and the mounting portions (11) located at both ends of the cover are provided. The vertical section of (11) should be of a size that roughly matches the vertical section near the end (A) of the wall balustrade, and the bellows part (12) that can expand and contract between the mounting parts (11) (11) at both ends. ) Is further formed, and the mounting portions (11) and (11) and the side wall of the wall balustrade are tightened with bolts and nuts, etc. to be fixed ”.

[0007]

[Action]

 The above technical means act as follows. The wall balustrade rubber cover (1) is made of rubber with excellent elasticity and durability, and the bellows part (12) is formed in the center part of the rubber cover (1), so that the play space (B) is Even if it expands or contracts, it can be absorbed by expansion and contraction of the bellows part (12) of the wall balustrade rubber cover (1).

Further, with respect to vertical displacement such as ground subsidence, the wall balustrade rubber cover (1) is elastically deformed and absorbed. Further, in this rubber cover for wall balustrade (1), the vertical section of the mounting part (11) has a size substantially corresponding to the longitudinal section near the end (A) of the wall balustrade, so that the wall balustrade can be easily mounted. One mounting part (11) of the rubber cover (1) for use can be put on the vicinity (A) of the end of the wall balustrade on one side.

[0009]

【effect】

 In this case, even if the clearance (B) at the end of the wall balustrade is displaced, the bellows part (12) of the rubber cover (1) for the wall balustrade deforms following this and absorbs the displacement. As a means for fixing a bellows-like rubber plate to each of the end faces of the wall balustrade, there is the one in Jitsukaihei 2-1480 No. 13, but this one is narrow between the ends (A) and (A) near the end of the wall balustrade. It is necessary to fix the bellows rubber plate in the space.

However, with the present invention, bolts and nuts can be tightened from the side of the wall balustrade, and work is performed in a narrow space between the end portions (A) and (A) of the wall balustrade. I don't need it.

[0011]

【Example】

 Next, the embodiments of the present invention described above will be described in detail with reference to the drawings. In the first embodiment of the present invention, as shown in FIG. 1, the wall balustrade rubber cover (1) has a U-shaped cross section, and the mounting portions (11) (11) at both ends are formed. A bellows portion (12) is formed between the two.

Then, one surface of the above-mentioned mounting portion (11) is clamped by the holding metal fitting (13) and the surface corresponding to these near the end portion (A) of the wall balustrade, and they are bolted (17). -Fix with the nut (22). That is, as shown in FIG. 3, the strip (2) is embedded near the end of the balustrade made of concrete, and the clamp (13) is attached to the bolt (17) protruding from the strip (2). It is fixed with the nut (22).

If this fixing work is performed on the outer circumferences of the mounting portions (11) and (11) at both ends of the cover (1), that is, the road side surface, the upper surface, and the outer surface, the mounting portions (11) and (11) The bellows part (12) located between (1) and (3) closes the clearance (B). Further, in the present embodiment, as a cover for the clearance (D) of the ground covering, a plate-like ground covering rubber cover (10) is attached to the finger joints (F) (F) from the bottom of the wall balustrade rubber cover (1). It is arranged in the part up to.

This ground cover rubber cover (10) is fixed to the ground cover by a bolt (18) and a nut (23) on the ground cover via a holding plate (14), and the other is placed in a free state. , This free end slide absorbs the displacement in the play. In addition, as shown in Fig. 3, since the apex of the bellows is located inside the extension line (Z) of the outer periphery of the attachment part (11), the apex of the bellows protrudes more than necessary, which may cause a traffic obstacle. Never be.

Furthermore, reinforcing fibers (15) of a core material are added to the material of the wall balustrade rubber cover (1) to increase the tensile strength of the wall balustrade rubber cover (1) itself, It is tough. This wall balustrade rubber cover (1) has the mounting parts (11) (11) at both ends firmly fixed as described above, and the bellows located between the mounting parts (11) (11). Since the part (12) is highly elastically deformable, when the clearance (B) in the wall balustrade expands and contracts, the bellows part (12) expands and contracts according to the expansion and contraction of the clearance (B). It elastically deforms and absorbs this.

Next, in the second embodiment shown in FIGS. 4 and 5, the bolting points of each mounting portion (11) are set only to the road side surface and the upper surface, and bolting from the outside of the road is performed. It was unnecessary. In this structure, the structure of Example 1 has a completely hollow structure, while a partition wall is provided at the boundary between the mounting part (11) and the bellows part (12) to reinforce the structure, and the route in the wall balustrade is improved. On the outer surface of the wall, only the part near the upper end is left and the part below it is removed to form a stopper (16) for preventing the wall balustrade rubber cover (1) from falling off, as shown in FIG. .

Therefore, since only the upper part of the road outside surface of the mounting portion (11) is covered near the end (A) of the wall balustrade, the rubber cover (1) for the wall balustrade is held on the outside of the road by pressing the metal fittings. It is not necessary to clamp it with (13) and the corresponding surface near the end (A) of the wall balustrade and tighten it with bolts. This embodiment has the same effects as those of the first embodiment, and since it is not necessary to work from the outside of the road, the mounting work can be performed more safely and easily.

The materials used for the rubber cover (1) for wall balustrade in the above examples are EPM (ethylene propylene rubber) or EPDM (ethylene propylene rubber) excellent in elastic deformability and durability. The diene rubber). These rubbers are also excellent in resistance to heat, light, and the outside air, that is, weather resistance, and thus are desirable as materials for the rubber cover (1) for wall balustrades used outdoors.

Materials other than this may be used as long as they exhibit the same or higher performance.
