DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention mainly deals with a middle pillar reinforcing frame in a subway or other premises, but it is intended to provide a structural member suitable for handling other frame-shaped structures and other various heavy objects. Installation method and installation equipment.

[0002]

2. Description of the Related Art An example of installation of a middle pillar reinforcing frame in a subway or the like as an example of a frame-like structure will be described. At present, the aging of subways and other premises and reinforcement against earthquake resistance are being made,
As one of the reinforcing methods, a method of installing a precast concrete reinforcing frame (hereinafter referred to as a reinforcing frame) which is divided into upper and lower portions between middle pillars is performed.

[0003] That is, as shown in FIG. 18, in a subway or the like, a center pillar 1 that separates the up and down lines is provided between the upper floor plate 2 and the lower floor plate 3 and at a predetermined interval in the horizontal direction. Has been established. When the middle pillar 1 of this concrete is deteriorated and reinforced, the deteriorated portion of the lower floor plate 3 is repaired in advance, and the cradle concrete 7 is constructed. First, a U-shaped lower reinforcing frame 5a is set in the cradle concrete 7 in the space 4 between the adjacent center pillars 1 and fixed, and then the inverted U-shaped upper reinforcing frame 5b is joined to the joint end face. 6 Next, the gap between the lower surface of the lower reinforcement frame 5a and the cradle concrete 7 is filled with mortar 7h, and the temporary receiving jack 11 is installed in the gap 12 between the upper surface 10 of the space and the upper reinforcement frame 5b to exchange the upper load. Perform Then, the deteriorated portion of the center pillar is replaced, and then the temporary receiving jack 11 is removed, so that both sides of the upper and lower reinforcing frames 5b, 5a are integrally arranged along the side surface of the center pillar 1. By doing so, the center pillar 1 is reinforced.

In the conventional reinforcing method using the reinforcing frame, there is a problem how to rationally and quickly install the upper and lower reinforcing frames 5b and 5a at the position of the space 4. In particular, in a narrow premises, installation of a heavy object such as a reinforcing frame is low in work efficiency in manual work and is troublesome work. However, a large hoist cannot be used because of a low head and a narrow place. Furthermore, there is a limit to the time that can be used for installation, and the installation must be performed in a short time at midnight outside the operating hours of a subway or the like.

Therefore, conventionally, the reinforcement frame is suspended and installed by using the reinforcement frame suspension truck 14 shown in FIGS. 19 and 20. The suspended carriage 14 has a carriage main body 17 to which traveling wheels 16 traveling along rails 15 are attached.
A plurality of pillars 18 stand up. The upper ends of the columns 18 are connected by an upper horizontal frame 20, and the left and right columns 18 are reinforced by braces 21 to form a frame of the suspended trolley 14. A lifting ramp 22 is provided therebetween.

The upper horizontal frame 20 is provided with a girder 23 made of H-steel so as to be able to advance and retreat toward the center column 1 at right angles to the traveling direction of the hanging carriage 14, and further along the girder 23. A trolley 24 is provided so that it can run freely, and a chain block 25
Is provided. The girder 23 has a manual winch 27 provided on a hanging support frame 26 hanging from the upper horizontal frame 20.
The part of the annular chain 28 that moves by the lock is locked.

When the upper and lower reinforcing frames 5b and 5a are installed on the center pillar 1, the hanging carriage 14 is caused to travel along the rails 15 and the rail clamp 3 is positioned at the reinforcing frame construction position.
The hanging truck 14 is fixed using the 0 and the fixing chain 31 and the journal jack 32 is driven to take measures to prevent the hanging truck 14 from tilting and falling to the center column 1 side.

Next, the upper and lower reinforcing frames 5b and 5a, which have been transported to a construction site in advance by a transporting vehicle (not shown) different from the hanging vehicle 14, are mounted using arbitrary fixing brackets. ,
Or, as shown in the drawing, a lifting rod 33 attached to a chain block 25 is used to lift the girder 23 by operating a manual winch 27, and a gear trolley 24 running along the girder 23; 25, the upper and lower reinforcing frames 5b, 5b
a is installed at a predetermined arrangement position.

[0009]

SUMMARY OF THE INVENTION A conventional suspension truck 14
Does not have the function of transporting the reinforcement frames, and therefore, there is a problem in that a dedicated transport vehicle different from the hanging cart 14 is required to transport a plurality of reinforcement frames to a predetermined location. further,
In the conventional suspension cart 14, the operation of installing the reinforcing frame in a predetermined place includes the lifting operation by operating the chain block 25 of the reinforcing frame, and the lateral movement of the geared trolley 24 along the girder 23 with respect to the center column 1 direction. Operation only,
Not only is the handling operation of hanging the reinforcement frame limited, but also the operation relying on human power over a relatively wide handling range of the reinforcement frame, such as operation of the moving chain block to the position where the reinforcement frame is hooked on the lifting rod. Must be used together. Therefore, in the construction method relying on human power by the hanging cart, it is difficult to work and the danger is high, and therefore, improvement of the working environment has been demanded.

According to the present invention, a single truck has both functions of transporting a reinforcement frame and suspending and installing the reinforcement frame, and further, operability and safety are improved by substantially eliminating work by human power. Therefore, an object of the present invention is to provide a structural member installation apparatus and an installation method that solve the conventional problems.
