Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for lifting up membrane roofs in air line structure roof structures made of flexible materials such as swimming pools, gymnasiums, exhibition halls, etc.

(Prior Art) Conventionally, in constructing a membrane roof for this type of structure, a method has been used in which cables are installed in the roof installation space in advance, and membrane panels are attached one by one at a predetermined location.

(Problems to be Solved by the Invention) However, buildings in which such membrane roofs are used are often buildings with very large floors, such as covered baseball stadiums, and in such cases, Installation of membrane panels often involves dangerous work at height.

(Means for Solving the Problems) The present invention has been proposed in order to solve the above problems. At the same time as assembly, stiffeners were attached to the circumference I# of the same membrane roof.

Next, the membrane roof is lifted onto the outer roof support structure, and the same structure Kj [This is a membrane roof gluing method characterized by anchoring the peripheral edge of the roof].

(Function) As described above, in the present invention, the entire roof is assembled on the ground by connecting the ventral panels immediately below the construction part of the air membrane structure roof, and the peripheral edge of the roof membrane thus assembled is After attaching the stiffeners, the roof membrane was hoisted onto the roof support structure around its outer periphery for 5K, and at this time the stiffeners prevented the roof membrane from deforming.

After the roof membrane is lifted onto a roof support structure, the peripheral edge of the roof membrane is anchored to the same structure to complete the construction of the roof membrane.

(Effects of the Invention) According to the present invention, all the assembly of the membrane panels constituting the membrane roof is done on the ground, which eliminates the need for dangerous high-place work, which would otherwise be hindered by strong winds. There are no problems, and quality control is carried out adequately.

Since the membrane roof assembled on the ground in Matatonoyo 5 is lifted from the outer support structure, there is no need for large heavy machinery for erection, and there is no need for scaffolding for erection.
! This will shorten the construction period and reduce construction costs.

Moreover, since a stiffener is attached to the outer peripheral edge of the membrane roof, the membrane roof does not deform during lifting operations.

(Example) The present invention will be described below with reference to the illustrated embodiments.

Above the entrance eaves (1) of the air membrane roof structure, the membrane surface grooves wound into rolls are stocked and set on the joint stand (3) in the pool room using a crane (2).

(See Figure 1) Next, pull out the membrane panel (4) set on the joint stand (3) and join the next membrane panel (4). The joined membrane panels are placed on a float (4) made of styrofoam or the like so as not to be damaged, and are moved by floating on the water surface of the pool (5).

(See FIG. 2) In this case, the membrane panel may be mounted and connected to a trolley having running wheels at the bottom.

In this way, the joining of the membrane surface nononel (4) is completed and the membrane roof (
When B) is assembled, a stiffening material (6
) is attached. (See Figure 3) Figures 7 to 9 show the attachment part of the stiffener to the interlayer panel A panel (A1) K, and the angle pieces (7) and the both sides of the membrane panel (AI) Sandwich the aluminum pieces (8) and tighten them with bolts (9), and abut the seat plate aG on the vertical piece of the angle piece (7). - Apply stiffening material to the seat plate 01 and the angle piece (7). (6) is fixed via Upol)Ql).

Figures 1θ to 11 show the attachment parts of the lifting jigs α to the end membrane surface panel (A2).
The edge of 2) is sandwiched between a lifting jig Q3 equipped with 7 lifting hooks and a lower aluminum piece α4, and fastened with a pole QS.

Next, the membrane roof (B) is attached to a roof support structure (
The traction machine (D) K mounted on C) is then hoisted to a predetermined height via a temporary suspension rope (E) (see Figure 4), and the support structure (C) K is then manually attached to the membrane bottom. Raise the membrane up to the roof support beam at the top and secure the membrane bottom and cable end. (See Figure 5) Next, the lower part of the membrane roof (B) is pressurized with air to complete the construction of the membrane roof. (Refer to Fig. 6) According to the method of the above embodiment, the work of assembling the membrane roof (B) using the membrane panel (4) is carried out on the ground directly under the erected part of the membrane roof (B). There is no danger (no work is hindered by strong winds, quality control is sufficiently carried out, and after the assembly of the membrane roof (B) is completed, the traction machine can be removed from the support structure (C) on its outer periphery. (Since this is carried out using ropes and temporary suspension ropes (E), heavy machinery and scaffolding are not required for the erection of the membrane roof (B).
) Kyotsu [Deformation and distortion of the membrane surface are prevented, and according to this embodiment, the construction period is shortened and the construction cost is reduced.

Although the present invention has been described above with reference to embodiments, the present invention is of course not limited to these five embodiments, and can be modified in various ways without departing from the spirit of the invention. be.
