Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wastewater treatment structure for an expansion/contraction device installed in a structure such as a concrete track bridge.

[Conventional technology]

Conventionally, the wastewater treatment structure for this type of structural expansion and contraction equipment is as follows:
In particular, three types are known: those that do not treat wastewater, those that are equipped with a drainage gutter, and those that are non-drainage type.
Although expensive, non-drainage type lanos are suitable for elevated bridges in urban areas and residential areas where noise is a problem, and have recently been widely adopted.

Figure 7.8 shows the conventional structure of this non-drainage type.
51 is a structure, a flange 52 is formed on the upper part of the structure 51, a face plate 53 is provided on the upper surface of each flange 52, which allows the structure 51 to expand and contract due to temperature changes, etc. Backup material 54 at the opposite bottom
is fixed, an adhesive is applied to the facing surface of the structure 51, and then a liquid elastic sealant 55 is filled, the elastic sealant 55 is solidified and cured, and drainage from the expansion gap 56 is treated. There is.

[Problem that the invention seeks to solve]

However, when filling the elastic sealing material 55, mixing of the main agent and curing agent, stirring, mixing, etc.
A liquid elastic sealing material 55 is made by performing secondary stirring and mixing,
A worker passes it through the expansion gap 56 and attaches it to the structure 51 from above.
The work is cumbersome because it requires pouring the material between the opposing surfaces of the pipes to fill it, which has the disadvantages of extremely low work efficiency and high construction costs.

[Means for solving problems]

The present invention aims to eliminate these disadvantages, and its gist is that the present invention is provided in a portion that allows the opposing structures to expand and contract, and is provided with elasticity that may be present between the opposing structures. A wastewater treatment structure for a structure expansion/contraction device is characterized in that a sealing member made of a material is provided on one or both of the structures.

[Effect]

A sealing member made of an elastic material that can be interposed between opposing surfaces of the structure is formed and placed on one or both of the structures.

〔Example〕

1 to 6 show preferred embodiments of the present invention;
．． 2 shows the first embodiment, FIG. 3 shows the second embodiment, FIG. 4 shows the third embodiment, and FIGS. 5 and 6 show the fourth embodiment.

In the first embodiment shown in FIG. 1.2, l is a structure, a flange 2 is formed on the top of the structure 1, a face plate 3 is provided on the top surface of each flange 2, and the structure The expansion and contraction gap 4 allows for expansion and contraction due to temperature changes, etc.

Reference numeral 5 denotes a sealing member made of an elastic material, and in this case, the sealing member 5 is extruded from rubber.

Reference numeral 6 denotes a guide member, and the guide member 6 is attached to the opposing surface of the structure 1 with bolts 7 and nuts 8, and the seal member 5 is formed with an engaging portion 9 that engages with the guide member 6.

Since this first embodiment has the above-mentioned configuration, the sealing member 5 manufactured in advance can be interposed between the opposing structures l.
In this case, the guide member 6 allows easy insertion from the lateral direction, making it unnecessary to fill the liquid elastic sealant as in the past, significantly improving work efficiency, and reducing construction costs. I can do it. Figure 3,
Embodiment 2.3 in FIG. 4 shows a modification of the cross-sectional shape of the sealing member 5.

In the fourth embodiment shown in FIG. 5.6, the sealing member 5 is formed in parts,
As shown in FIG. 5, one sealing member 5a is adhered to one structure 1, and the other sealing member 5b is adhered to the other structure l, and then the structure l is moved closer to each other as shown in FIG. The sealing member 5 is brought into elastic contact.

The second to fourth embodiments also provide the same effects as the first embodiment.

Note that the cross-sectional shape of the seal member 5 may be designed with appropriate changes.

〔Effect of the invention〕

As described above, the present invention allows a pre-fabricated sealing member to be interposed between opposing structures, which eliminates the need for filling a liquid elastic sealant as in the past, significantly improving work efficiency. It is possible to reduce construction costs.

As described above, the intended purpose can be fully achieved.
