Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This first introduction relates to a method for borrowing large-space three-dimensional truss relics.

[Problems with conventional technology]

Many buildings that require a large space for use, such as exhibition halls and indoor charm halls, are enshrined as relics of three-dimensional trusses. , the top and bottom chord materials and the first material to be installed on the roof are made in advance to a size that can be sent to the factory in Jomon or upper chords.
Conventionally, the method of assembling the lower chord I and the bottom material one by one on site has been generally performed, but this construction method requires large-scale temporary scaffolding, which requires a large amount of materials and manpower. need,
It was inevitable that construction costs would rise significantly. In addition, since most of the suspension was installed at a high place, problems occurred in terms of safety and construction accuracy.

[Target of shot Q'3] This shot 1. jll was created in order to solve the above-mentioned conventional problems, and it is possible to m#@ even a large space truss at low cost and in an extremely short period of time. To provide 6 methods for cultivating relics in a large space that can significantly increase the safety and construction viscosity of the cropping by allowing most of the cropping to be carried out close to the field surface. With the goal.

[Development of invention]

This invention is applied to three-dimensional truss borrowed relics, which are generally triangular in plan view or can be divided into approximately triangular parts, and when constructing them, the pillars on the outer periphery are first desecrated,
Next, the roof of the borrowed three-dimensional truss is placed on a plane, with the central part f
Form a roughly triangular roof with the apex c as its apex, and connect its base end to the above-mentioned house by connecting the triangular roof with the apex M'. By doing so, the above objective t- is achieved.

[Collection of Inventions Mffll Hereinafter, this development μmJ'ff: To explain with an example shown in the figure, first, a floor of a three-dimensional truss relic l is constructed in a fixed area using the conventional construction method, and several The rPI is carried out at regular intervals in the circumferential direction of the floor 2, and a lift-up support 4 is installed in the center of the floor 2.

Next, the three-dimensional truss borrowed relic 1 (1) was assembled by dividing the raft into several approximately triangular roofs 6.6 with the center part as the apex on a plane with the m root part, and the base end side of the raft was divided into several approximately triangular roofs 6.6 with the center part as the apex. Pivots 7i and f are attached to the upper end.

When renting the approximately triangular roofs 6, 6, the outer fl! The inner roof portion 6b extends from the inner portions 6α, 6α and the outer portions 3, 3.

It can be divided into 6b and 11 pieces, or it can be placed on a pillar as it is. Next, to explain the dividing method, the inner side of the outer tree roof parts 6α, 6α is pivoted to the upper end of the pillar 3゜3, and the outer wall is supported by temporary supports 7, 7 installed below. or directly supported on the ground (
f'ffSee figure 3). On the other hand, the inner roof parts 6b, 6b are 6
Separately from α and 6α, I put 114 in the inner opening and assembled it.

After completing the assembly of the outer f'R root parts 6cL and 6α, attach the outer f'Q ends of the outer P parts 6α and 6G to the temporary support 7.

Junction with 6α.

When the substantially triangular roofs 6, 6 are joined to a total length r, first, the substantially triangular Fl [60] is lifted up to a predetermined position by a hoisting device 8 such as a hoisting winch, and once fixed to the lift-up support 4.

Next, the substantially triangular roof 6 on the opposite side is similarly lifted up to a predetermined position using the lifting device 8.

Furthermore, the two opposing substantially triangular roofs 6, 6 are connected by a connecting member 9. By doing this, the zero structure at the time of borrowing can be constructed more stably (see Figure 6).

More than! 1] After the construction is complete, connect the nearly triangular roofs 6 and 6 with a connecting panel IO, and construct a conical relic (εr41 [4+see Figure 2).

The lift-up support column 4 can be constructed by leaving the three-dimensional truss C'' as a column in the center of the relic l (or by constructing it).
It will be removed after the final T.

Further, the substantially triangular roofs 6, 6 may be assembled into a plain triangular shape on the flat surface, or may be assembled into a round or M shape.

FIGS. 10, 110 and ε312 show some modified examples of the present invention.

Then, assemble it and then take it outside! There are 11 inside the circle of I-Yakibe 6α! ! j erect the roof house 66 and the outside timber part 6α in a continuous manner.

After about 1 hour of assembling the approximately triangular roof 6, the temporary supports 12 were removed and the "11 triangular roof tables 6" were lifted up.

When the height of the I"U on the roof 5, which can be convex, is approximately 1, remove the temporary supports 12 and borrow the pillars 3 and 3. Also, remove the temporary supports 11 and 11.

[Effect of emitted 1j] The light beams with the above C) are formed, and by using this construction method, most of the construction is done when constructing the borrowed three-dimensional truss. When pulling up the roof, by placing a pivot point 11 near the center point 16 of the roof part and pivoting it to the pillar,
This can be done with a small amount of force, and the safety of the form and high construction accuracy can be ensured.

In addition, since the cost of converting scaffolding can be kept to a minimum, even large-scale solid objects (relics) can be destroyed at low cost and in an extremely short period of time.
