Description

The present invention is a temporary pipe used when performing renewal work or repair work of water supply pipe lines (water supply pipe lines) laid in multi-story buildings such as condominiums, schools, hospitals, buildings, etc. In particular, it relates to a plumbing fixing bracket for fixing a vertical plumbing path forming a temporary plumbing path to a handrail wall or handrail provided in an outer corridor or an outer staircase of a building of several stories. It is.

In general, water supply pipes that are laid in multi-story buildings such as condominiums, schools, hospitals, buildings, etc., have been used for many years, and have developed inside water supply pipes such as galvanized steel pipes. Rust, etc. causes red water outflow, sliminess in pipes, generation of bacteria, decrease in flow rate and water pressure, generation of scale, outflow of scale, etc., resulting in deterioration of water quality and sanitary issues, as well as damage to packing. Various adverse effects such as water leakage accidents due to deterioration will occur.

Therefore, in a multi-story building such as an apartment complex, when the above problem occurs, the water supply pipe line is renewed or repaired. At this time, in the renewal work or repair work of the water supply pipe laid in the building, the pipe renewal or repair due to the long-term water outage is not permitted because the residents live.

In this way, in the conventional renewal work and repair work of water supply pipes, since it is not permitted to renew or repair pipes due to water outages for a long time, a method of installing so-called temporary pipes is adopted (for example, , see Patent Documents 1 and 2).

Vinyl pipes, polyethylene pipes, and the like, which are lightweight and excellent in handleability, are widely used in place of metal pipes such as steel pipes for the temporary pipes. In particular, when laying a temporary pipeline using vinyl pipes, an adhesive is used to connect the vinyl pipes together for permanent bonding.

However, when vinyl pipes are used, not only does it take time to join the vinyl pipes together, but there is also the problem that a considerable amount of time is required from the completion of joining to the start of supply of tap water.

In addition, when removing temporary pipes, it is necessary to cut the pipes because they are permanently connected, which consumes time and labor costs. It is necessary to dispose of all the road-forming members as scraps, which poses many problems in terms of resource conservation and environmental protection.

On the other hand, the applicant of the present application has developed a temporary pipeline that solves the above-mentioned problems, 122209 (patent document 5).

That is, although not shown, each of the temporary pipelines is formed of a straight pipe, an elbow, a tee, a tube with a different diameter, an expandable pipe, or the like, which is formed of a polyethylene resin material. At both ends of the temporary piping unit formed by connecting the two, polyethylene resin cylindrical joints are connected by butt fusion, and the tubular connection between the pipe bodies, between the temporary piping units, or between the pipe body and the temporary piping unit An annular flange formed on the outer peripheral surface of the distal end portion of the opposed cylindrical connecting portion is covered with an annular packing, and the annular flange and the annular packing are divided into two parts to form a housing-shaped pipe joint. It is formed by embracing and tightening and fixing, and airtightly connecting the pipe bodies, the temporary piping units, or the pipe bodies and the temporary piping units with an annular packing and a housing-type pipe joint.

In this way, the temporary pipe line is formed by airtightly connecting the pipe bodies, the temporary pipe units, or the pipe bodies and the temporary pipe units with the annular packing and the housing-shaped pipe joint. The construction period can be shortened by easily forming a pipe path, and the pipe body and the temporary piping unit can be easily separated simply by removing the pipe joint and the annular packing, and when disassembling the temporary pipe path There is an advantage that the pipe body, temporary pipe unit, and pipe joint are hardly damaged and can be reused.

In the renewal work and repair work of the water supply pipeline using the temporary pipeline described above, if there is no installation space for the temporary pipeline, the number of vertical pipelines that form the temporary pipeline will be limited during the renewal work or repair work. Installed on the outside of a storey building. That is, a plurality of vertical pipe lines of the temporary pipe line are arranged in parallel at predetermined intervals outside the handrail walls and handrails provided in the outer corridor or the outer staircase of the building. A water supply pipe such as a water supply hose is used to connect the vertical pipe line and the water meter (or meter unit) housed in the meter box of each dwelling unit in the building.

In addition, each vertical pipeline is provided from the roof to the lowest floor of the building, and the upper end of each vertical pipeline is connected to an existing water pipe connected to a tank or pump for water supply. and tap water flows in from the water pipe.

Furthermore, when each of the vertical pipes is installed outside the handrail wall or handrail provided in the outer corridor or the outer staircase of the building, the pipe main body or the temporary pipe unit is looped from the roof side of the building to the lower floor. The packing and the housing type pipe joint are used for sequential connection. This is because, in multi-story buildings such as collective housing, water is supplied from the roof in many cases, so each vertical pipe line is constructed from the roof of the building toward the lower floors.

However, when constructing a vertical pipeline, pipe bodies and temporary piping units (hereafter, pipe bodies and temporary piping units are referred to as piping members) are sequentially connected from the roof side of the building downstairs using housing-type pipe joints. If this is done, the pipe member may fall off due to its own weight, leading to an accident resulting in injury or death, or the building or the fallen pipe member may be damaged or damaged.

Therefore, when constructing a vertical pipeline, in order to prevent the plumbing members (pipe bodies and temporary piping units) that form the vertical pipeline from falling accidents, part of the piping members should be installed on each floor of the building. Fixing to handrail walls and handrails provided on stairs is performed.

When fixing a part of the pipe member of the vertical pipe line to the handrail wall or handrail, as shown in FIGS. (See Patent Documents 6 to 8, for example).

However, since the conventional pipe fixing bracket 100 shown in FIGS. 16A to 16C is of a type in which the pipe fixing bracket 100 itself is driven into the wall surface of the building with anchor bolts, screws, etc., the water supply pipe line When the temporary pipe line and the pipe fixture 100 are removed after completion of the renewal work or repair work, a hole is made in the wall surface of the building, which necessitates repair work and increases the burden on the worker. At the same time, there is a problem that the construction time is lengthened.

Also, the metal fittings 100 for pipes are fixed to metal members such as handrails in buildings by welding. .

In addition, in buildings such as collective housing, it is necessary to restore the current state after construction, and when fixing piping members to the handrail walls and handrails of the building, anchor bolts and screws can be driven into the wall of the building according to the client's request. sometimes not.

In this case, the main body of the pipe is tied to the handrail of the building using a rope or wire rope, or a wooden member is attached to the handrail wall or handrail of the building, and the pipe fixture is attached to the wooden member with screws or the like. I am trying to install it.

However, in this case, there are cases where the piping member cannot be completely fixed to the handrail wall or the handrail of the building due to individual differences.
