Description

[Detailed description of the invention] [Industrial application field] This invention is useful for constructing a steel roof of a large space such as a gymnasium, or for constructing a roof on top of an existing facility.
A structure used in the traveling construction method, which is suitable for constructing multi-story buildings without interrupting the use or operation of existing facilities during the construction period, and without being subject to major restrictions from surrounding buildings, etc. More specifically, the present invention relates to an improvement in a sliding device for a structure comprising a pedestal portion for mounting and supporting a traveling structure, and a rail portion for slidably supporting the pedestal portion.

[Conventional technology]

As shown in Fig. 2, this type of sliding device is composed of a rail 1' having a cross-sectional shape similar to that used for railway tracks, and steel wheels 2' attached to a structure K'. It is known,
Alternatively, as shown in Fig. 3, it consists of a channel steel rail 1'' whose inner surface has been subjected to friction reduction treatment and a structure K'' side steel cylindrical body 2'' whose outer surface has been subjected to friction reduction treatment. has already been proposed by the applicant.

Further, as shown in FIG. 4, a rail having a cross-sectional shape and provided with a large number of stiffeners d perpendicular to the web c between the upper and lower flanges a and b,
A pair of vertical plate parts f are provided on both sides of a horizontal plate part e facing the upper flange a, and a pedestal part with a friction reduction treatment applied to the lower surface of the horizontal plate part e is constructed in 1983. It is known from the publication No.-79730.

[Problem that the invention attempts to solve]

The conventional example shown in FIGS. 2 and 3 above has the following problems.

That is, in these sliding devices, the part that supports the structure has a relatively complicated structure,
Due to the unstable shape, extremely high precision manufacturing and installation are required not only to keep the structure horizontal for safety reasons, but also to respond to the recent trend of larger structures. For safety reasons, the entire sliding device must be large enough to withstand the weight of such large loads, which increases production and transportation costs, and if the sliding device is enlarged, The drawback was that it was too large to be used for the target structure, and its versatility was low.

The conventional example shown in FIG. 4 described above is small, has high strength, and seems to have improved versatility, but it has the following problems.

That is, since this rail has a large number of stiffeners d arranged perpendicular to the web c, the rail has many constituent parts, and the welding work for the stiffeners d has to be extremely complicated. Manufacturing efficiency was low and manufacturing costs were high.

It goes without saying that it is desirable to not only reduce the sliding friction of the horizontal plate part e against the upper flange a, but also to allow the vertical plate part f to smoothly slide against the side surface of the rail. In the conventional example, the substantial side surface of the rail (the continuous side surface over the entire length of the rail) is simply the end surface of the upper flange a, which has a minute width equivalent to the plate thickness of the upper flange. Even if an attempt was made to weld a flat stainless steel plate to the vertical plate part to make the sliding of the vertical plate part smoother, it would not be possible to take up the welding allowance. Therefore, when the vertical plate comes into strong contact with the side surface of the rail, the frictional resistance between the vertical plate and the side surface of the rail increases, making it impossible to transfer the structure smoothly.

The present invention provides a sliding device for a structure that can solve all of the problems of the conventional example described above.

[Means for solving problems]

The technical measures taken by the present invention to solve the above problems are as follows.

That is, in the sliding device for the structure described at the beginning, the present invention has a width equal to the spacing between the upper and lower flanges between both edges of the upper and lower flanges of the horizontally arranged H-shaped steel. A pair of flat bars are welded so that they fit between the upper and lower flanges up to the middle of their plate thickness, stainless steel plates are welded to the outer surfaces of both flat bars, and stainless steel plates are welded to the upper surface of the upper flange. A stainless steel flat plate is welded to form the above-mentioned rail part, and a horizontal plate part faces the stainless steel flat plate welded to the upper surface of the upper flange, and a stainless steel flat plate welded to the outer surface of each flat steel plate faces the horizontal plate part. The pedestal portion is characterized in that it has a pair of vertical plate portions, and a friction reduction treatment is applied to the lower surface of the horizontal plate portion and the opposing side surfaces of both the vertical plate portions, respectively.

[Effect]

According to the above configuration, a stainless steel flat plate is welded to the upper surface of the upper flange of the rail portion, and a friction reduction treatment is applied to the lower surface of the horizontal plate, and since this portion slides on the stainless steel flat plate, The pedestal part slides smoothly.

In addition, the vertical plate portion of the pedestal portion is guided by both sides of the rail portion, so that the structure can be transferred straight. In this case, a stainless steel flat plate is welded to the outer surface of the flat steel that forms both sides of the rail part, and a friction reduction treatment is applied to the side surface of the vertical plate part so that this part slides on the stainless steel flat plate. ,
Even if the vertical plate comes into strong contact with the side of the rail,
Sliding is done smoothly.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 1, a pedestal part 6 on which a traveling structure 5 is mounted and supported is mounted on a rail part 4 which is removably attached to a beam 1 via steel sleepers 2 with bolts and nuts 3. The structure is slidably engaged and supported to constitute a sliding device for a structure in the traveling construction method.

The rail portion 4 is constructed as follows.

That is, a width equal to the distance between the upper and lower flanges 4a', 4a'' is provided between the edges of the upper and lower flanges 4a' and 4a'' of the H-section steel 4a which is placed horizontally on the sleeper 2 and welded. A pair of flat steel bars 4b, 4b having the same thickness are welded so as to be fitted between the upper and lower flanges 4a', 4a'' up to the middle of their plate thickness. , 4a'' and the upper and lower end surfaces of the flat bars 4b, 4b that protrude outward from the end surfaces. Both flat bars 4b, 4
Stainless steel flat plates 4c, 4c are provided on the outer surface of b, respectively.
A stainless steel flat plate 4c' is welded to the upper surface of the upper flange 4a'.

The pedestal portion 6 has a horizontal plate portion 6 facing the stainless steel flat plate 4c' welded to the upper flange 4a'.
A pair of vertical plate parts 6b, 6b facing the stainless steel flat plates 4c, 4c welded to the outer surfaces of the respective flat bars 4b, 4b are welded to both ends of the horizontal plate part 6a, and the lower surface of the horizontal plate part 6a and the both The vertical plate portions 6b, 6b are constructed by applying a friction reduction treatment 6d to the opposing side surfaces thereof, respectively.

Incidentally, as the friction reduction processing 6d, for example,
This is done by attaching a film of ethylene tetrafluoride resin or a film made of a sheet of glass fiber (or glass wool) impregnated with ethylene tetrafluoride resin.

[Effect of idea]

Since the present invention has the above-mentioned configuration, the rail part has a rectangular cylindrical shape with the upper and lower flanges and both flat bars, and the pedestal part has a downward opening with a horizontal plate part and both vertical plate parts. Because of the U-shape, the sliding device has the advantages of being compact, strong, and highly versatile, and also has the following unique effects.

Between both edges of the upper and lower flanges of the H-shaped steel placed horizontally, a pair of flat steel having a width equal to the spacing between the upper and lower flanges is inserted between the upper and lower flanges to the middle of the plate thickness. In other words, the structure is such that a pair of flat bars placed along the length of the H-shaped steel function as a continuous stiffener between the upper and lower flanges. Compared to the case where a large number of stiffeners perpendicular to the steel web are provided at appropriate pitches to ensure the required strength, the number of constituent parts of the rail section is smaller, and the upper flange end face of the upper flange end face and the upper and lower end faces of the flat steel are The corners of the protruding parts can be welded in the longitudinal direction of the rail, making welding work easier, improving manufacturing efficiency and reducing manufacturing costs.

In order to weld a pair of flat steels between the upper and lower flanges, fitting them between the upper and lower flanges up to the middle of the plate thickness, these flat steels form a continuous wide rail side surface in the longitudinal direction of the rail. Therefore, it became possible to weld a flat stainless steel plate not only to the top surface of the rail, but also to the side surface of the rail, and on the top surface of the rail, welded the friction-reducing part on the bottom surface of the horizontal plate of the pedestal. slides on a flat stainless steel plate, and the friction-reducing portion of the vertical plate of the pedestal slides on a flat stainless steel plate on the side of the rail, making it possible to transfer the structure extremely smoothly.
