2. Description of the Related Art At conventional construction sites, there is a desire to improve the working conditions of site workers, and plans are being made to increase the number of vacation days available. For this reason, there is a growing demand for shorter construction times than in the past.

0003

[Problem to be solved by the invention] However, on the other hand, work at construction sites is greatly affected by the weather;
These weather conditions were a considerable constraint in terms of both the process and workability. Therefore, in order to at least minimize the influence of the weather on site work, temporary roofs have been implemented in which temporary frames are erected at construction sites and covered with sheets. However, such conventional temporary roofs require a lot of time and effort to construct, and in the case of a roof with a large span, construction becomes even more difficult. Additionally, when a temporary roof is installed as described above, the problem arises that the temporary roof becomes an obstacle during lifting operations using cranes, etc., and actually hinders the efficiency of the work. had. An object of the present invention is to provide an all-weather temporary roof structure that can solve these conventional problems.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. FIG. 1 is a schematic vertical cross-sectional view showing the structure of a floating all-weather temporary roof according to this embodiment, and FIG. 2 is a side view of the temporary roof. It is a diagram.

The floating all-weather temporary roof 1 in this embodiment is placed on top of temporary pillars 4 which are installed along the outer periphery of a building 3 under construction at a construction site 2 and which also serves as earth retaining. ing. Note that FIG. 1 illustrates a state in which a basement portion is being constructed.

The temporary roof 1 has a self-floating helium beam 7 constructed by filling a thin-film, lightweight, long tube 5 with helium gas 6. The amount of helium gas 6 to be filled will vary depending on the design conditions, but it must be sufficient to obtain at least a buoyant force that is greater than the weight of the entire temporary roof 1. In addition, the material of the long tube 5 needs to be thin and lightweight in order to reduce the weight of the entire temporary roof 1 as much as possible.
For example, it is desirable to use a film made of vinyl chloride.

In this embodiment, as shown in FIG. 2, by arranging a predetermined number of helium beams 7 in the row direction of the temporary roof 1, the entire upper part of the construction site 2 is covered. A floating all-weather temporary roof 1 is formed by joining both ends of the helium beam 7 in the beam-to-beam direction to the temporary pillars 4 at the construction site 2 using linear bodies such as ropes 8. In this embodiment, the rope 8 is extended parallel to the helium beams 7 from one temporary column 4 to the other temporary column 4 in the inter-beam direction along the joint of each helium beam 7. It is used as a tension rope.

Furthermore, as shown in FIG. 2, each helium beam
At both ends of the rope 7 in the inter-beam direction, a seam is provided between each of the ropes 8.
Covered with ToS to improve rain protection performance. Further, in this embodiment, the end of each rope 8 is connected to a rail placed on the temporary pillar 4 using appropriate means such as a roller.
It is slidably joined to the column 9 in the row direction.

Furthermore, as shown in FIG. 2, in this embodiment, three helium beads are arranged consecutively in the column direction.
The ends of the beams 7 are integrally joined by a membrane material 10 having a width approximately equal to two helium beams 7.

In installing the temporary roof 1 having the above-described structure, first, the temporary roofing material consisting of the long tube 5 which is not filled with helium gas 6, the membrane material 10 and the rope 8 is placed in a predetermined position. Both ends of each long tube 5 are slidably connected to the rails 9 on the corresponding temporary columns 4 by ropes 8 as described above. When helium gas is pressurized and filled into each long tube 5, each long tube 5 expands as shown in FIG. 1 or 2.
A helium beam 7 having a predetermined internal pressure is formed and placed in a floating state above the construction site 2 due to the buoyancy of the helium gas 6, thereby forming the temporary roof 1.

In this embodiment, the work of forming the temporary roof 1 only requires attaching each rope 8 to the rail 9 and filling helium gas 6 as described above, so that work efficiency is improved. This is much improved compared to the conventional example, and the temporary roof 1 can be installed in a short time and at low cost. Furthermore, since it is self-floating, it can be safely and easily applied even to large-span roofs. In addition, since the long tube 5 and the membrane material 10 are integrated in advance, sufficient rain protection performance can be exhibited and work can be performed even in rainy weather.
Process control can be performed reliably, and construction periods can be easily shortened.

Furthermore, in this embodiment, each rope 8 is
The membrane material 10 is slidable along the column 9 in the row direction.
By expanding and contracting the parts, each helium beam 7 can be pulled towards one end in the column direction, and the remaining part can be made into an open space, so even when lifting work with a crane etc. The temporary roof 1 does not get in the way and does not impede work efficiency. In addition, the helium beam 7 itself
Since it is in a self-floating state, the above-mentioned moving work can be performed with very good workability.

[0016] The length of the temporary roof 1 in the column direction is made shorter than the length of the construction site 2 in the column direction, so that only a necessary part of the construction site 2 is covered with the temporary roof 1. In this case, the degree of freedom of movement of the temporary roof 1 is further expanded, so that the work can be made more efficient.

[0017]Also, an air beam structure is conventionally known in which the air beam itself is given bending rigidity by increasing the internal pressure, thereby resisting external forces, but with this structure, it is difficult to maintain extremely high pressure. This has the drawback of requiring blower equipment and high-strength membrane materials. On the other hand, the helium beam 7 in this example can easily self-float at low internal pressure, so there is no need for blower equipment or high-strength membrane materials, and a large-span structure can be easily formed. .

Note that both ends of the temporary roof 1 in the row direction can be left open, so in this case vehicles and the like can be carried into the construction site 2 from here.

Next, FIGS. 3 and 4 show another example of joining the helium beams 7. In this embodiment, as shown in FIG. (
In this embodiment, the unit units U are continuously joined together along the inter-beam direction, and each unit U
It is configured such that only both ends in the row direction (both ends in the left-right direction in the figure) need to be joined to each other on site. As for this joining means, in this embodiment, as shown in FIG. 4, a connecting sheet piece 11 is installed in advance at the joint J so as to protrude from the long tubes 5 and 5 over the entire length in the direction between the beams. The pair of sheet pieces 11 are then connected to each other by a fastener 12.

In this embodiment, during temporary construction work, it is sufficient to connect each unit U with the fastener 10 and then arrange it at a predetermined position, and the other steps are the same as in the first embodiment. It is.

Further, the means for joining the sheet pieces 11 to each other may be as shown in FIGS. 5 to 7. That is,
In the example of FIG. 5, the sheet pieces 11 are connected to each other with Velcro tape 13, and in the example of FIG. 6, the sheet pieces 11 are stacked vertically and formed at a common position. In the example shown in FIG. 7, the sheet pieces 11 are stacked one on top of the other, and a helium beam 7 is formed to protrude from one side of the helium beam 7. The connection is made by fitting the tip of the connecting piece 16 to a button 17 provided at a corresponding position on the other helium beam 7.

Further, as in the embodiment shown in FIG. 8, a female fitting portion 19 as shown in the figure is provided on one side of the connecting pieces 18 which are formed protruding from the opposing helium beams 7, and a female fitting portion 19 is provided opposite thereto. A male protrusion 20 may be formed on the other connecting piece 18, and the connection may be performed by fitting the male protrusion 20 into the female fitting part 19.

[0023] In addition, each of the temporary pillars 4 in the above embodiment
is made vertically expandable and retractable at the ground level using appropriate known means such as hydraulic or pneumatic jack-up methods, and when installing the temporary roof 1,
It is also possible to connect each rope 8 to the rail 9 after lowering each temporary pillar 4 to the lowest height position using this expansion/contraction means. This will further improve workability.

Further, in the above embodiment, an example was shown in which the entire temporary roof 1 could be moved in the row direction by slidingly joining both ends of the rope 8 to the rail 9. For example, both ends of the rope 8 can be removably connected to the upper end of the temporary pillar 4, and by removing each rope 8, the entire temporary roof 1 can be moved. Good too. Furthermore, it goes without saying that the present invention is not limited to the above embodiments, and that various modifications can be made without departing from the spirit of the present invention.
