Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a proposal for a construction method for an air membrane structure construction.

There are almost no examples of structures with air membrane structures in Japan, but the construction methods currently in use are as shown in Figures 1 and 2.

That is, as shown in FIG. 1, the wire 1 is first erected on the ring beam 4 at the upper end of the body 3 by a tow truck 2, a military helicopter 21, etc. (Fig. a), and then the wire 1 is erected at the intersection of the wire 1. Tighten and attach the membrane 5 to the wire l.
Alternatively, as shown in FIG. 2, a stage 7 is installed over the entire surface below a predetermined σ film surface level, and this is used to conduct the wire 1. There are two methods for applying the membrane 5.

In both cases, the construction of the membrane roof structure will be carried out after the internal structures such as the bleachers S are completed.

However, when it comes to construction methods such as diagonal construction, the quality control of intersections, membrane connections, etc. is insufficient in the construction method shown in Figure 1 for the membrane roof structure due to the work being done at height. The construction method shown in Figure 2, on the other hand, However, construction at a high place requires a huge number of stages, which poses problems in terms of construction time and cost.Also, in terms of construction time, it is possible to construct internal structures in the open air. Since the construction period is limited, the construction period will inevitably be affected by the weather, but even though there are many construction projects outside the prefecture that have to overcome short construction periods, especially in areas outside the prefecture where orders are currently tight, The disadvantage is that there are many days when work is not possible due to this, and the construction period becomes even tighter.

The present invention has been made in view of the circumstances of the slope, and has been made to develop a new construction method that can completely eliminate the above-mentioned Xle points. Prior to the construction work, one end of the wire is locked to a wire hoisting guide post erected on the periphery of the body and raised to a predetermined position midway through the post, and in this state the wire intersections are tightened. In addition, the membrane pasting will be carried out on the ground, and after completion, the wire will be raised further and one end of the wire will be attached to the mounting bracket installed on the ring beam at the top of the structure, after which the post will be removed. Workability (quality): Membrane roof frame work can be done with wires, and membrane construction can be done on the ground instead of work at high places.
In addition to aiming to improve safety, shorten construction time, and increase safety,
After the construction of the membrane roof is completed, water is stored in the upper part of the deflated membrane surface, and a rope or the like is stretched between the central lower surface of the membrane surface and the ground to stabilize it against wind. The main advantage of this system is that it enables work to be carried out on internal structures such as bleachers and internal facilities under curing conditions, regardless of the weather, thereby shortening the construction period.

Hereinafter, this will be explained in detail based on embodiment figures.

That is, in FIG. 3, reference numeral 8 in the figure is the outer peripheral frame, and 9 is an erection wire hoisting guide boss installed on the periphery of the outer circumferential frame 8. Each construction wire is installed facing each other around the outer peripheral frame 8, and the construction wire 10 is controlled to move upward along the post 9. Various driving means are available, such as a combination of a stroke jack and a pinion rack, but in the illustrated example, a metal fitting 1 attached to the end of the construction wire 10 is used.
1 is wound up by a winch 14 installed on the ground via a wire rope 13 provided at the upper end of the boss 9.

In this way, once both ends of all the construction wires 10 have been assembled to the post 9, they are raised under centralized control to a predetermined position midway through the post 9, which is a predetermined height suitable for ground work, and then stopped once. Tightening of the intersection points of the construction wires is carried out by ground work, as well as the pasting work of the membrane 15.

Thereafter, this intersection tightening is carried out, and the construction wire 10', which has been pasted with a membrane, is raised again, and the end fitting 11 is pivoted to the mounting anchor 17 provided on the ring beam 16 at the upper end of the outer frame 8. By attaching it, the power of construction becomes five women.

Thereafter, the wire rope 12 is removed from the end fitting 11 and the post 9 is removed.

In the figure, the dotted chain line of the construction wire 10' shows the inflated state in which the roof membrane swells when internal pressure is applied.The construction wire one end fitting 11 and the construction wire hoisting in the diagonal embodiment. Details of the guide post 9 are shown in Figures 4 and 5.
As shown in the figure.

Figures a and b of fR4 show one end fitting 11 of the construction wire, which is a substantially U-shaped frame Ll & front wall 11t) through which the bolt rod ioatm at the end of the construction wire 10 is passed, a washer 18, and a stopper 19. Attach it at..., and attach both Il.

1lcL, and by inserting a stop bolt (not shown) between this and the through hole 17a formed at the tip of the mounting anchor 17, the erection wire lO can be connected to the ring beam 16. A sheath-shaped hanging hook lie is welded to the front end of the frame ILa, and the wire rope 12 is fastened to this to hang the metal fitting 11, and further, Both side walls lie $

Next, the post 9 is shown in detail in FIG. 5, and in the illustrated example, as described above, the HfII pillars 20 and 20' are opposed to each other at a predetermined interval, and the yoke 21 is attached at a predetermined position. 21 and 21' in the figure are the rollers 11g e 11.
The rail angle fIJA 22 welded to the ends of the H steel columns 20 and 20' is a spacer across between the ring and the arm 16 to prevent sexual intercourse.

5 for the membrane roof frame in the construction method of the present invention which is constructed as if it were tilted upward.
In this case, all of the tightening of wire intersections and the application of the membrane can be done on the ground, so the work can be done under good quality control, and the work efficiency can be improved, shortening the construction period.
Safety and cost are significantly improved, and especially in the case of large-scale counterfeit purchasing, there will be significant benefits in terms of safety, construction time, and cost.

Next, as shown in FIG. 6, water 24 is stored in the upper part of the deflated membrane roof 23, which has been completely erected, and a rope 25 is placed between the lower surface of the center of the membrane surface and the ground. . . . etc. are stretched over the roof to stabilize it against the wind, and under the protection of the membrane roof 23, internal work on the internal structures such as the bleachers S and internal facilities is carried out.

Similarly, in case of excess water storage due to rain or the like in this state, a drain 26 may be provided at the center of the membrane surface, and water overflowing from each grid may be drained by flowing downward to control the water storage.

This internal work is completely unaffected by the weather, which greatly contributes to shortening the construction period.
