Description

  The present invention relates to a diffusion plate mounting rib having an integral structure that enables a diffusion plate to be installed safely, quickly, and at low cost in order to obtain the same diffused light as that of a light diffusion type skylight from an existing skylight made of only glass.

  Many glass-only skylights are installed on the existing roof, and when the sun is directly incident, it is hot and the working environment is poor. Also, bright and dark places are clear and unsuitable for illumination. A light diffusing skylight has also been developed, but it will continue to spread.

To install a diffuser plate on an existing glass skylight and make it a light diffusing skylight, you must cut off the glass joint seal, remove the glass, attach the diffuser plate, and restore the glass. It has deteriorated due to use, and it is a difficult task in terms of both cost and difficulty of work such as replacement of a new one.
It is desired to quickly install an aerial work vehicle and a work platform from the floor without touching existing skylights.

  Patent Document 1 was devised to solve this problem, but it requires a lot of time to manufacture special mounting bolts, joiners, tightening with electric tools, many components, high costs, and work. Not popular.

  Since it is a work at a high place, safe and quick installation work is required. For this reason, there is a demand for an integral mounting rib that has as few components as possible and that does not require the use of a power tool. Since work is performed on non-operational days, it is necessary to finish the work as soon as possible.

  For example, Patent Document 2 is an effective technique in which a diffuser plate is attached to a frame of a skylight made of only glass with screws or the like, and direct light is diffused, but it is not suitable for being attached to an existing skylight having a steel structure. In Patent Document 3, there is anxiety about deterioration of screws and bolts for mounting the diffusion plate to install it from the outside. It is not a technique for quickly installing on an existing mounting steel frame without touching the skylight as in the present invention. Patent Document 4 is a method of laying a diffusion plate under the glass from the beginning of the new installation, and is not a technique for attaching the diffusion plate to the mounting steel later.

  By integrating all functions for attaching the diffuser plate into an integral structure mounting rib, a construction method using only two component members, that is, the integral structure mounting rib and the diffuser panel, is possible. The integrally mounted mounting rib has a bolt and a wing nut portion on the holding plate portion of the diffusion plate. The electric tool may not be used by manually tightening the wing nut.

  In order to secure the thermal expansion and contraction width of the diffusion plate, the short width of the presser plate portion is 12 mm. When the diffusion plate and the mounting rib are temporarily placed, the presser plate portion enters the diffusion plate-diffusion connection portion and serves as a gauge. Lift the long width of the presser plate part by about 10 mm, rotate it 90 degrees, and tighten the wing nut part by hand to fix the diffusion plate. In places where strong winds are generated, a stopper can be provided at the lower part of the integral diffuser plate mounting rib.

  Since the mounting ribs of the diffuser plate are integrated into a single structure, construction can be performed in a short time and safety work at a high place is ensured.

  The component member to be installed does not need to use an expensive special member, which reduces the cost, shortens the construction period, and reduces the burden on the adopting side.

It is the figure which looked at the diffused board installation completion from the top. It is sectional drawing of the skylight only of general glass. It is a figure of the diffusion plate attachment rib of an integral structure. It is detail drawing after diffusion plate installation completion. It is a temporary placement figure of the diffusion plate attachment rib of a structure integral with a diffusion plate. It is the completion detailed drawing in which the diffusion plate attachment rib of the integral structure with the diffusion plate was installed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The installation work of the diffuser plate 001 is required to be quickly, safely and accurately installed at a high place during limited holidays. FIG. 1 is a top view of the diffuser plate after installation, and shows that the diffuser plate 001 and the diffuser plate mounting rib 002 having an integral structure are installed at the joint between the diffuser plate 001 and the diffuser plate 001 on the existing mounting steel frame 003. Yes. FIG. 2 is a cross-sectional view of a general skylight window made only of glass. FIG. 6 is a diagram necessary for explaining that a diffusion plate 001 is installed on a mounting steel frame 003 below a glass 004. FIG. 3 is a view of the diffusion plate mounting rib 002 having an integral structure. The diffusion plate mounting rib 002 has both ends of the diffusion plate mounting rib 002 at the both ends of the integral structure, and the diffusion plate mounting rib 002 of the integrated structure from the existing mounting steel frame 003 is provided below the integral structure diffusion plate mounting rib 002. In addition to having the side shake prevention portion 006, the upper surface of the integrally formed diffusion plate mounting rib 002 also has a diffusion plate installation portion 007 that is a connecting portion of the diffusion plates 001. The diffusion plate pressing plate portion 008 is fixed to the bolt and nut portion 009, the short width is a shape and size for securing the thermal expansion / contraction width of the diffusion plate 001, and the long width is for pressing the diffusion plate 001. It has a length. It shows that the diffusion plate mounting rib 002 has a single structure.

  FIG. 4 is a detailed view after the diffusion plate installation is completed. It is shown that a diffusion plate mounting rib 002 having an integral structure is installed on the existing mounting steel frame 003 together with the diffusion plate 001 and pressed by the diffusion plate pressing plate portion 008. FIG. 5 is a diagram showing a temporary placement state of the diffusion plate mounting rib 002 integrally formed with the diffusion plate 001. A gap that requires a thermal expansion / contraction width of the joint of the diffusion plate 001 is a short of the diffusion plate holding plate portion 008. It shows that the shape is secured. FIG. 6 is a completed detailed view in which a diffusion plate mounting rib 002 that is integral with the diffusion plate 001 is installed. The diffusion plate holding plate 008 is lifted by about 10 mm and rotated 90 degrees, and the diffusion plate 001 is tightened with a bolt wing nut 009. It shows that it is fixed.

The work procedure is to place two diffusion plates 001 on the existing mounting steel frame 003, and then insert a diffusion plate mounting rib 002 having a single structure into the joint of the diffusion plates 001. It is confirmed that the mounting steel frame 003 and the diffusion plate 001 are stored in the lateral displacement prevention portions 005 and 006 of the diffusion plate mounting rib 002 of the integral structure, and the thermal expansion / contraction width of the diffusion plate 001 is secured by the width of the diffusion plate holding plate portion 006. Confirm that the diffusion plate holding plate 008 is lifted by about 10 mm, rotate it 90 degrees, and turn the bolt and wing nut portion 009 by hand.
Thereafter, the same operation is repeated under water or above water and completed.

  Since work is directed upward from an aerial work platform or work platform, there are demands that the number of components is as small as possible and that work can be performed easily and safely. The present invention is an integral structure diffuser plate mounting rib 001 characterized by combining the constituent members into one, and the diffuser plate 002 can be installed without an installation tool.
