BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention relates to a module construction method in a steel structure building zone, which can be applied to the assembly and construction of steel buildings and the assembly and installation of power generating sets, steel making machines, or paper making machines, or apparatuses and equipment for chemical plants etc. which are installed in the buildings.
2. Background Art
The module construction methods in a steel structure building zone shown in FIGS. 26 and 27 have so far been used.
The method shown in FIG. 26 is called a pile-up method, in which a member 021 forming a steel building 02 or an apparatus 03 to be installed in the steel building is lifted and transported for installation and assembly as a single item or a block forming a certain small section by using a crane 01 installed on the ground.
The method shown in FIG. 27 is called a push-up method in which after a roof 06 and a top floor 07 are completed, they are raised (jacked up) by using hydraulic equipment etc. to produce a space for installing the next floor under the top floor 07, the next floor to be connected to the top floor 07 is built in this space, the roof 06 and the top floor 07 is lowered (jacked down) to incorporate with the lower floor, and the incorporated structure is jacked up to produce a space for installing the next floor under the incorporated structure, thus the building structure is assembled successively.
In FIG. 27, reference numeral 08 denotes an external protective cover, 09 denotes a material carrying unit, and 010 denotes a slide strut.
(1) With the above-described pile-up method, the weight and size of a single item of apparatus or a block formed by incorporating the items are limited by the crane capacity such as working radius, lifting capacity, lifting height, and lift, so that the work efficiency is decreased. When the building and the apparatus to be installed in the building are assembled separately, it is necessary to provide an upper or a side space for transportation to the place where the apparatus is installed. Therefore, the term of works is extended due to the adjustment of the work schedule or the work progress and for other reasons.
Even when there is no limit of crane capacity and the building and the apparatus to be installed in the building can be assembled as a block, the next step cannot sometime be performed because of the relationship between the floors.
(2) With the above-described push-up method, the next step cannot be performed before the entire floor is completed. For example, if a trouble occurs in a zone on one floor, jacking up cannot be performed before that floor is completed, so that the work for the next floor cannot be started, causing waiting time. An object of the present invention is to provide a module construction method in a steel structure building zone which solves the above problems with the conventional methods. With the method of the present invention, a block can be carried in from one direction and joining and lifting by jacking up can be performed for the steel structure of any shape. Therefore, work can be done up to the maximum limit of jack capacity without being restricted. In addition, since a steel structure can be constructed by being divided into zones, work can be done independently for each zone. If a trouble occurs or the progress of work is behind schedule in one zone, the work in other zones is not affected.
DISCLOSURE OF THE INVENTION
Accordingly, according to the present invention defined in claim 1, column assembly which is formed as one column by joining several pillars with beams, vertical braces, and horizontal braces; constructing a gate-shaped truss assembly by installing hydraulic jacks as a first elevating device on top of two truss column assemblies assembled to the top floor, by joining a plurality of beam members, which are carried on the ground between the truss column assemblies, with vertical and horizontal braces, and by lifting the truss beam assembly formed into one beam to the top of
