Description

  The present invention includes a traveling rail attached along a structure, a movable suspension equipped on the traveling rail, and a work floor or other suspension suspended by the movable suspension. It is related to the vertical surface construction work device and construction work method for performing maintenance inspection and other construction work on the vertical surface (same as construction work surface). Specifically, it is a specific outdoor storage tank that is difficult to construct a scaffold from the ground or the base surface, In order to carry out detailed inspections and other construction work on structures such as high-rise chimneys, a traveling rail that can form a track is used regardless of whether the construction work surface is a two-dimensional plane or a three-dimensional plane (curved surface). The present invention relates to a vertical construction work apparatus and construction work method in which a suspended object is suspended from a movable suspension machine mounted on a traveling rail, the suspended object is opposed to a construction work surface, and is configured to be movable.

  Here, the specific outdoor storage tank refers to a structure represented by a crude oil reserve tank, an offshore crude oil reserve tank or a crude oil storage ship having a diameter of about 80 m. The construction work surface in this case is mainly those side plates (a vertical surface comprising a two-dimensional plane or a three-dimensional plane).

  In addition, a work floor or a work platform and a scaffold in the case of a moving scaffold or a suspended scaffold may be referred to interchangeably. Also, the vertical movement and the vertical movement are used interchangeably.

  2. Description of the Related Art Conventionally, a mobile scaffold device using a suspended scaffold that is movable in a horizontal direction or a vertical direction is known in construction work that is performed by constructing a work floor on a vertical surface (especially an outer wall) of a structure such as a high-rise building. ing.

  An overview of this type of mobile scaffolding device is as follows: a traveling rail attached along the structure, a movable suspension equipped on the traveling rail, and a work floor suspended by the movable suspension (moving scaffold) ) Is a component.

  Here, a rack rail type mobile suspension scaffold device is known in which a movable suspension machine travels on a rail by rack and pinion drive (see, for example, Patent Documents 1, 2, and 3). However, the gondola cannot be hung. In addition, the traveling rail is laid straight in the horizontal direction or the vertical direction, and the vertical movement of the work table (same as the suspension scaffold) is similar to ladder movement, so long span traveling movement and large area planar movement are considered. Not.

  Moreover, the mobile scaffold apparatus which uses a gondola as a work floor is known (for example, refer patent document 4, 5 and 6). The construction method is a so-called gondola construction method, which proposes a moving scaffold useful for exterior construction of high-rise buildings by using a gondola, which is a cage element, on a traveling rail. The traveling rail is laid in a straight line in the horizontal direction with a span for each work area, and after the work is completed, it is lifted together with a crane or the like and moved to the upper part of the next work area. However, the structure is large and can only be installed on the roof of a building. In addition, construction work due to traveling movement and gradient movement due to the laying of curved rails on a construction whose construction work surface is a curved surface is not considered.

On the other hand, what proposed the working floor of a tank is known (for example, refer patent document 7).
A characteristic structure of this work floor is a moving scaffold that revolves around the outer periphery of the tank using a wind girder as a fulcrum, and the movable scaffold is composed of a revolving scaffold and a suspended scaffold connected to the lower part of the revolving scaffold. It has a caster and a guide caster for turning the track, and the suspension scaffold has a multistage scaffold and a ladder.

  The suspension scaffold here is held on the swivel scaffold via the slide unit, and is held so as to be able to separate from (retreat from and retreat from) the outer peripheral surface of the tank. It avoids obstacles such as riser pipes and sprinkling nozzles so that it can move around. It should be noted that each work deck of the suspension scaffold can be assembled and disassembled using a connecting plate. However, it is assumed that this moving scaffold device is a fairly heavy equipment with a two-stage structure consisting of a swiveling scaffold and a suspended scaffold connected in series, and its construction and moving operation are not easy. Is done.

  The following are examples of problems to be solved by the present invention (including public requests at present).

  (1) Even if the construction work surface is either a two-dimensional plane or a three-dimensional plane (curved surface), a track can be formed with a long span (for example, the entire circumference of the tank). In particular, there are no curving rails that lay horizontally or slope.

  (2) Points that should be taken into account when the suspension moves vertically and horizontally (horizontal direction, vertical direction, or composition direction).

  (3) A point where self-running inspection equipment should be considered in addition to the suspended scaffolding as a suspended object suspended from the movable suspension machine equipped on the traveling rail.

  (4) Naturally, the purpose and effect in accordance with “Guidelines for detailed inspection of side plates of specified outdoor storage tanks [March 29, 2013; Fire Risk No. 48 and Fire Risk No. 49]” The point which comprises.

  In these circumstances, the present inventors have mainly used the side plates (two-dimensional plane or three-dimensional plane) for structures represented by crude oil reserve tanks, offshore crude oil reserve tanks or crude oil storage vessels having a diameter of about 80 m. We have been researching and developing on-site technology when the vertical surface is a construction work surface.
