Both ends of the high-strength steel wires 16a and 16b are connected to the shed 1 through fixing fittings 17 (Figs. 8 (a) and 8 (b)).
, See FIG. 9).

The hut beam 1 formed as described above is stretched between framed scaffolds 2 and 2 assembled on the left and right sides of the work yard A at predetermined intervals in the row direction of the roof.

At least two frame scaffolds 2 are further built according to the size of the roof at predetermined intervals in the girder direction, and are connected by a plurality of tie members 5 so as to be self-supporting. It is reinforced by the brace 6 of the book.

A caster 7 with a jack is attached to the lower end of each column 2a of the framework scaffold 2 so that the caster 7 can run on the rail 3 freely, and the level can be freely adjusted by jack operation. Has become.

A support beam 8 is laid over the frame scaffold 2 in the direction of the spar beam, and a support 9 for receiving an end of the cabin beam 1 is mounted on the support beam 8.

An H-shaped steel is used for the supporting beam 8, and the supporting beam 8 is hung horizontally between the frame scaffolds 2, 2 and is fixed to the upper horizontal member 2b of the frame scaffold 2 by a plurality of clamps 10. ing.

A plurality of bearing bodies 9 are mounted on the supporting beam 8 in accordance with the number of shed beams 1 installed, at predetermined intervals in the longitudinal direction of the supporting beam 8, and a plurality of supporting bodies 9 are mounted on the upper flange 8a of the supporting beam 8. It is fixed by a clip or a fixing bolt 11.

A support plate 4 attached to the end of the shed 1 is attached to the support body 9 and fixed by a plurality of clips or fixing bolts 12.

Further, a connecting member 13 for preventing lateral collapse of the shed 1 is provided between the adjacent sheds 1,1. Angle steel or the like is used for the connecting member 13, and is connected to the upper chord member 1a of each shed 1 by a plurality of U bolts 14 (see FIGS. 4 and 5).

If necessary, the number of the frame scaffolds 2 is increased in the girder direction and the support beams 8 are extended in the girder direction.
In addition, the roof area can be expanded in the girder direction by newly bridging the hut beam 1.

A roof sheet 15 is placed on the shed 1 constructed in this manner so as to cover the entire shed 1, 1.

The roof sheet 15 is formed into a panel shape of a size that is easy to handle, for example, by attaching a daylightable polyethylene film to both sides of mesh streaks, and is firmly tied to the shed 1 so as not to be blown by the wind. ing. A tent may be used instead of the roof sheet 15.

The hut beam 1 is provided with various equipment such as a sprinkler, an illuminating light, and a monitor camera, as necessary, in order to ensure the safety of work (not shown).

FIGS. 7 (a) and 7 (b) show examples of the use of the all-weather temporary roof according to the present invention. Accordingly, the span, the number of installations, the installation intervals, and the shape of the hut beam 1 are determined.

Embodiment 2 FIG. FIG. 10 shows another embodiment of the present invention. In the figure, a plurality of framework scaffolds 2 are stacked while being connected according to the height of the building B under construction, and a plurality of framework scaffolds 2 are attached to the lowermost framework scaffold 2. , A supporting beam 8 is bridged over the topmost framed scaffold 2, and a cabin beam 1 is bridged over the supporting beam 8. Other configurations are exactly the same as those of the first embodiment, and therefore only the reference numerals are given and the description thereof is omitted.

Also, by increasing the number of steps of the framework scaffold 2, the height of the temporary roof can be freely increased according to the height of the building B under construction.

[0024]

The present invention has the above-described construction, and in particular, a plurality of framed scaffolds are added in the direction of girder of a temporary roof, a supporting beam thereon is extended, and a shed beam is newly provided on the supporting beam. The roof can be expanded freely by bridging, and the roof can be raised freely by stacking a plurality of framed scaffolds, so it can be used not only as a temporary roof for ground work, but also for the construction of middle- and high-rise buildings. It also has the effect of being used as a roof.

The shed burr is formed of two upper chord members made of rebar, one lower chord member, and a plurality of diagonal members into an arch shape having a substantially V-shaped cross section, and both end portions and apexes thereof. Since high-strength steel wires are laid between the middle and middle parts, it is possible to prevent deformation and deflection of the shed with the increase in span and build a temporary shed with a large area. Since it is much easier to process, it has the effect of easily manufacturing a shed.

Also, the high-strength steel wire is not directly bridged between both ends (legs) of the hut beam, but between the end (legs) and the top (ridge) and in the middle. Since the high-strength steel wire is bridged in a relatively short section even if the hut has a large span, it is easy to install the high-strength steel wire. Slack after installation can be reduced.

Further, since the supporting beams are bridged over the frame scaffolds, the adjacent frame scaffolds can be integrally connected to each other, and both ends of each hut beam are supported by the supporting beam and the supporting body. Since each is supported on the scaffolding,
Since each hut can be fixed at any position in the direction of the girder, it is easy to install the hut, and the load of the hut can be distributed to the frame scaffolding through the supporting beam, so it is also extremely stable in strength. .
