CONSTITUTION:Permanent columns 1 are erected at four corners of a building to be built. The permanent column 1 is reinforced by a reinforcing temporary column 2 via a support jack 3. A jack 4 for lift-up is installed at the top of the permanent column 1. A temporary pillar 5 for lift-up is installed at the intermediate position of the permanent columns 1. A hoisting wire 8 suspended from the jack 4 for lift-up is connected to the end of a truss roof 7 fabricated on the ground, and the truss roof 7 is lifted up. After the installation of roof is completed, the reinforcing temporary column 2 and the temporary pillar 5 for lift-up are demolished and removed from the permanent column 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to an apparatus for constructing large-space buildings such as gymnasiums, hangars, and warehouses.

[Prior Art] Conventionally, as shown in FIGS. 8(A) to 8(E), as a method of constructing this type of large space building, A. erecting main pillars 9 at predetermined positions of the building; B. Assemble the temporary columns 10 at the openings of the permanent columns 9, and C0 assemble these permanent columns 9.
Build the truss frame roof 11 on the temporary pillar 10, and then jack down the second jack 12 of the temporary pillar 11 to separate the temporary pillar 10 from the temporary pillar 11.
be received by the permanent pillar 9 from the imaginary line state to the solid line state, and then dismantle and remove the temporary pillar 11 to complete the large space building. As shown, A. First, assemble the temporary pillars 13, B.) Assemble the truss frame roof 14 on the ground, C. Lift up the truss frame roof 14 using the lift-up jack 15 attached to the temporary pillars 13, and D. After erecting the permanent pillars 16 under the truss frame roof 14 that has been lifted up, the truss frame roof 14 is lifted down and fixedly erected on the main pillars 16, and the temporary pillars 13 are dismantled and removed. A large space building was completed.

[Problem to be solved by the invention J However, among the conventional construction methods for large-space buildings mentioned above, the former Shankidowne method involves assembling the truss frame roof at a high place, so it is difficult to use scales, which is dangerous work, and the construction time is limited. On the other hand, the latter lift amplifier construction method requires large-scale temporary columns to support the entire load of the truss frame roof, resulting in wasteful construction time and construction costs. There were many problems.

The present invention was made in order to solve the above-mentioned conventional problems, and its purpose is to reduce the size of temporary columns, save construction costs, shorten construction period, and improve safety and quality. The present invention provides a construction device for large-space buildings that can improve management.

[Means for Solving the Problems] The construction device for a large space building of the present invention is attached to the top of a main pillar erected at an appropriate position of a building, and lifts the truss frame roof assembled from the ground. A lift-up gloss for the purpose of the construction, and an erected pillar that reinforces and supports the main pillar.
The present invention is characterized by comprising a support jack for jacking down which is inserted between the construction column and the main column.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

In Fig. 1, reference numeral 1 denotes permanent pillars, which are erected at the four corners of the building to be constructed. Although the main column 1 in this embodiment is a truss column, the present invention is not limited to this, but can include a steel column,
It may be a steel column such as a plate column, a reinforced concrete column, or a steel reinforced concrete column.

Reference numeral 2 denotes a temporary reinforcing column, which, as is clear from FIG. 2, reinforces the permanent column 1 via a support jack 3.

Further, a lift-up jack 4 is attached to the top of the main pillar 1.

This is a temporary pillar for a 5-beam 7-ton amplifier, and is installed at the open position of the permanent pillar 1 as necessary. As shown in FIG. 3, a lift-up jack 6 is attached to the top of the temporary pillar 5 for the 97 doorknob.

After constructing the permanent columns 1 and temporary columns 2 and 5, or in parallel with these construction operations, the truss frame roof 7 is assembled and raised on the ground, as shown in FIG.

As is clear from FIG. 5, the truss frame roof 7 is
Although it has a three-dimensional truss structure, any structure that can sufficiently withstand a large span frame may be used, and the structure is not limited to this.

When the ground assembly of the truss frame roof 7 is completed, the hanging wire 8 suspended from the above-mentioned 7
The lower end of the truss frame roof 7 is tightly tied to the end of the truss frame roof 7, and the truss frame roof 7 is lifted up.

As shown in FIG. 6, when the truss frame roof 7 is pulled up and fixed to the head of the main column 1, the main column 1 and the truss frame roof 7 are attached to a large space frame building. integrated as

Main pillar 1 and truss frame shop $f! 7 are integrated, the support jacks 3 reinforcing and supporting the permanent columns 1 are jacked down, the temporary reinforcing columns 2 are separated from the permanent columns 1, and the entire load of the truss frame roof 7 is transferred to the permanent structure. Move to column 1.

Transferring the load from the temporary state to the permanent installation is a two-step process to ensure smooth load transfer.
How to hold the jack down and conversely, support gloss 3
There is a method of first jacking down the vehicle and then releasing the lift-up jack 4; either method may be used.

Subsequently, the reinforcing temporary pillar 2 separated from the main pillar 1 is dismantled and removed, and at the same time, the lift amplifier temporary pillar 5 is also dismantled and removed to construct a large space building as shown in FIG.

[Effect of the invention 1 1) 177) The permanent pillar can be used as a pillar for lifting up, and the permanent pillar is used as the main pillar, and the temporary pillar is used as an auxiliary pillar by reinforcing the permanent pillar. Therefore, the scale of the temporary pillar can be reduced, and the assembly and disassembly and removal of the temporary pillar can be simplified, so that construction costs can be reduced and the construction period can be shortened.

2) Since the truss frame roof is assembled on the ground, there is less work to be done at heights, and work safety can be ensured, especially during strong winds.

3) Since excessive loads are not applied to the temporary columns, the foundations of the temporary columns can also be simplified, and only the foundations of the permanent columns need to be considered in the design.

4) Load transmission is a two-step process, and safety and accuracy can be confirmed without transferring a large load at the same time.

5) Since the stress conditions during permanent construction and temporary construction are almost similar, the number of permanently installed steel trusses can be reduced.
