Abstract

A construction method of a large space structure (1) in which the stress remaining after construction due to deformation during a lift up can be reduced. The construction method of a large space structure is characterized in that truss columns (21, 21) becoming the columns of a gate truss (2) are erected on the front (F) side at an interval in the lateral direction, a back side portion (4) is constructed on the rear (R) side, a truss beam (22) becoming the beam of the gate truss and a roof structure (3) extending from the truss beam toward the rear side are assembled in the vicinity of the ground, the truss beam and the rear end portion of the roof structure are lifted up to a predetermined height, the truss beam and the truss column are joined in such a state that the rear end portion is lifted to a higher position than the truss beam, and then the rear end portion is lowered and joined to the back side portion.

Description

technical field

[0001] The present invention relates to a method for constructing a large-space building such as a hangar for an airplane, a sports arena with a roof, and a warehouse where columns or walls cannot be provided in the middle. Background technique

[0002] In the past, as disclosed in Patent Document 1 (Japanese Patent No. 2945917) and Patent Document 2 (Japanese Patent No. 2979039), a large-space building was built by erecting a roof frame composed of trusses on columns erected at the four corners. methods are known.

[0003] Various methods have been proposed and implemented as a method of erecting the roof frame between the columns.

[0004] For example, there is a "descending construction" in which temporarily installed brackets are assembled in advance to the height of the roof frame, a lifting device is installed on the temporarily installed bracket, and the roof frame is assembled on the elongated lifting device, and then the lifting device is lowered. ...

Embodiment Construction

[0029] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0030] In the method for constructing a large-space building according to the present embodiment, the large-space structure 1 used as a hangar of an aircraft will be described as a large-space building.

[0031] First, refer to figure 2 , image 3 , Figure 8 The overall configuration of the large space frame 1 will be described.

[0032] The large space frame 1 is mainly composed of Figure 8 The "door" shaped truss 2 constituting the front F side shown in (a), such as figure 2 Shown as the rear part 4 of the rear support part, the side parts 5, 5 as the side support parts connected to the both sides of the rear part 4, and the rear part 4 and the side parts 5, 5 such as image 3 The shown roof frame 3 is formed.

[0033] The "gate" shaped trusses 2 as Figure 8 As shown in (a), it is a planar truss constructed by combining steel materials such as H-...
