Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a floor plate for an evacuation chute, and more particularly to a method for easily manufacturing a floor plate for an evacuation chute having a spiral structure.

Conventionally, the sliding surface of a spiral evacuation chute has often been constructed by arranging pipes in parallel, but there have also been cases where a plate has been laid on the sliding surface. When constructing a sliding surface by laying this plate material,
A floorboard is formed by cutting a board into an arc shape to match the width of the sliding surface, and the floorboard is installed with an inclination in the direction of spiral progression and in the radial direction, but at this time, unreasonable force is applied to the floorboard, causing distortion. If the distortion is large, wrinkles may appear on the sliding surface, and it is extremely difficult to manufacture floorboards that match the actual installation location correctly.

The present invention has been made in view of these manufacturing problems, and consists of pillars placed at predetermined intervals on the inner and outer curves of the full-scale plane perspective view of the evacuation chute obtained on the surface plate. Girder materials were installed at each pillar group along the inner circumference curve, and for the column group along the outer circumference curve, according to the calculated height of the evacuation chute at the position of each column. At the same time, a beam material is fixed between both girder materials to form a frame for making a mold, and then a mold making material is laid on the girders and beams of the framework, and the mold making material is covered with the above-mentioned material. A method for manufacturing a flooring material for an evacuation chute, characterized in that a mold is created by making a mold along a girder material, and then the shape of the mold is transferred to a floorboard material and cut out, The aim is to provide a simple method for manufacturing floorboards that correctly match the installation site.

Embodiments of the present invention will be described in detail below with reference to the drawings. First, as shown in FIG.
is drawn over a predetermined angle, and pillars 3, 3 are erected at predetermined intervals along the inner circumferential curve 2a and outer circumferential curve 2b of the plane perspective view 2. Next, as shown in FIG. 2, for the column groups 3, 3 along the inner circumferential curve 2a and the column groups 3, 3 along the outer circumferential curve 2b, evacuation at the position of each column 3 is performed. The heights h ₁ , h ₂ ... (see Figure 1) of the chute for use are determined, and the girder materials 4 are fixed in accordance with these heights h ₁ , h ₂ ..., and the girder materials 4 of both column groups 3 are fixed. , beam material 5 between 4,
5 is installed as a beam, and a frame 6 for making a receiving mold is completed by the column group 3, the girder material 4, and the beam material 5. In the above, the height of the evacuation chute at the position of each pillar 3 h ₁ , h ₂
... is determined graphically, and accurately determined so that the inclination in the helical direction and the inclination in the radial direction are obtained at the desired angles.

Next, as shown in FIG. , 7 are connected to each other, and a line along the girders 4, 4 is copied onto the mold making materials 7, 7 to create a mold 8. In this case, a line 9 is written on the mold making material 7 that protrudes outside the line along the girder materials 4, 4, and a mark is drawn on the missing part that does not reach the line along the girder materials 4, 4. 10 and the length of the shortage.

Next, the receiving mold 8 constructed in this way is transferred to the floor board material 11 as shown in FIG. By cutting the floorboard material 11 along this transferred line, a floorboard 12 for constructing a spiral evacuation chute can be obtained. This floorboard 12 is the fifth
As shown in the cross-sectional view, the side plate 1 is placed along the side edge.
3 and 13 are fixed to form a gutter-like evacuation chute.

In the above embodiment, as the mold making materials 7, 7, scraps of steel, iron plates, etc., and steel strips are used.
A plywood board or a flexible synthetic resin sheet can be used. In the case of rigid materials such as steel or iron plates, the mold 8 will be aligned with the floorboard of the actual evacuation chute, and the floorboard material 11 will be deformed to match this and the transfer work will be performed. On the other hand, in the case of a flexible material such as a synthetic resin sheet, the receiving mold 8 is stretched over a flat floor board material 11 and the transfer operation is performed.

According to the above embodiment, the dimensions of each three-dimensional part of the evacuation chute that will actually be constructed are determined on the mold making frame 6, so that the mold 8 can be accurately shaped into the actual evacuation chute. It will be a match. Thus, a floorboard 12 obtained by transferring the receiving mold 8 is obtained.

In the next step, the floorboard made in this way is twisted using the upper and lower molds of a press to form a curve and slope, making it possible to produce a floorboard with almost no wrinkles. An evacuation chute can be constructed by fixing the rear side plates 13, 13 together.

Furthermore, evacuation chutes reaching from high places to the ground are usually composed of rotating spiral chute, but it is possible to connect a plurality of evacuation chutes (sectors) formed through the floor plate 12 obtained in the above embodiment. Therefore, a plurality of required floorboards can be easily manufactured using a receiving mold 8. During the process of manufacturing this floor board, the side panels, handrails, flange joints, etc. may be temporarily fixed and processed.

As detailed above, the present invention is a method for manufacturing a floor plate for an evacuation chute configured in a spiral shape, and the inner circumferential curve and the outer circumferential curve of a full-scale plane perspective view of the evacuation chute obtained on a surface plate. Pillars are erected at predetermined intervals along the curve, and the height of the evacuation chute corresponding to the position of each column is set for the column group along the inner circumferential curve and the column group along the outer circumferential curve. At the same time, the girder materials are fixed, and a beam material is fixed between both girder materials to form a frame for making a mold.Next, a mold making material is laid on the girder and beam materials of the framework, and the mold is assembled. This method is characterized by creating a mold by making a mold along the girder material on the material to be created, and then transferring the shape of the mold to the floorboard material and cutting it. This has the effect of making it possible to accurately match the actual size of the floorboards that make up the system, and to easily manufacture them.
As a result, when assembling the evacuation chute, there is no need to apply excessive force to the floorboards, and there is no need to make fine adjustments to each part, so the assembly work can be done easily and in a short time. The ripple effect is also significant.
