DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a chimney inner tube and a pull-up device for the construction.

[0002]

2. Description of the Related Art For example, in a tower supported chimney,
Install a cylinder jack-up device on the ground or at the bottom of the supporting tower, jack up the cylinder, add another cylinder to the lower side in order, and attach a post attached to the top of the cylinder to be jacked up 2. Description of the Related Art A parallel erection method is known in which a crane is used to build another tubular body or the above-mentioned supporting steel tower on top of one another. As shown in the side view of FIG. 4, a jack-up device for this kind of construction is provided at the lower end of a long step rod 03 vertically engaged with a jack 02 provided on a fixed beam 01 of an outer cylinder. There is one that moves up and down while the movable beam 04 is supported. Here, the jack 02 has a fixed clamp 05 on the fixed beam 01 through which the step rod 03 is inserted, and a platform 0 on the fixed beam 01.
A ring-shaped movable beam 04 is supported by a plurality of jacks 02 and step rods 03 having the same structure, which are lifted and lowered by a center hole jack 07 attached via a center hole jack 07. Furthermore, as shown in the side view of FIG. 5, the side walls facing each other 0
In some cases, a movable beam 013 is supported on a climbing jack 012 that engages with a column 011 having a plurality of pin holes 010 having a constant pitch formed on the top and bottom of the movable beam 013. here,
Jack 012, with a pin cylinder box 015,016 and below the elevator cylinder 014 are provided respectively to pins cylinder boxes 015,016 of the upper <br/> under binds to the pin hole 010 of the post 011 alternately As the lifting cylinder 014 expands and contracts, the movable beam 013 is raised and lowered.

However, these means have the following disadvantages. (1) In the parallel erection method, if the outer cylinder is a chimney made of reinforced concrete and the inner cylinder is made of steel, it is difficult to make the construction of the outer cylinder and the push-up construction of the inner cylinder parallel at the same time. Generally, the outer cylinder of reinforced concrete was built first
Later , steel inner cylinders and elevator shafts were built inside. In this type of chimney, when a plurality of inner cylinders are built in the outer cylinder, the outer cylinders hinder the lifting and stacking of each inner cylinder by a crane or a hoisting device. In addition, if a plurality of jack-up devices are arranged at the inner bottom of the outer cylinder, the loading path of the inner cylinder block cannot be taken, so that one set of jack-up devices must be used to build the inner cylinder one cylinder at a time. There is a problem such as lengthening.

(2) In the jack-up device shown in FIG. 4, when the movable beam 04 is raised by the jack 02 on the fixed beam 01, a large number of rigid step rods 03 rise together in the outer cylinder. Since the space occupied by the step rod 03 when ascending is large, the influence on other operations is increased. Therefore, it is difficult for the movable beam 04 to increase the elevating distance. (3) In the jack-up device shown in FIG. 5, a large area is required for installation of the column 011 disposed around the cylindrical body.
It is difficult to install jacks for a plurality of cylinders inside the outer cylinder, and there is a problem that the height of the support 011, in other words, the height of the movable beam 013 cannot be increased very much.
