Description

[Detailed Description of the Invention] Technical Classification/Field> The disclosed technology applies to the technical field of fixing the membrane panel to the side plate of a low-temperature tank.

<Explanation of the gist> Therefore, the invention of this application involves transporting membrane panel blocks, which have been prefabricated in a predetermined wreath at a factory, onto the bottom plate of a tank, lifting each panel block one by one, and aligning the blocks to a predetermined position. This invention relates to a device directly used in method 1 of 1. The f,

Interfering with the work floor of the accompanying gondola, etc., it is possible to pass between the work floor and the cooling shrine on the side plate without touching each other and be lifted up, and through the f + h a IA. The present invention relates to a method for installing a membrane panel for a low temperature tank, which allows work operations to be carried out by hand, and a device directly used in the method.

<Prior art> As is well known, in low-temperature tanks, it is common to attach a membrane panel to the outer tank via a cold insulation material.
(This is an IP-like construction, but since the membrane panel usually has complicated corrugations, a membrane panel block of a specified square size unit is suspended and attached to it. .

It is easy to attach a work floor to the membrane panel 11 via a cold insulating material on the lifting platform and the side plate because it is a so-called mounted type, but it is easy to install it when the work floor is attached to the membrane panel 11 with a cold insulation material on the side plate. Attaching the membrane panel block takes the form of vertical attachment, so it is necessary to hang it from delivery, lift it up,
In addition, it is common for fixed operations to involve a lot of overhead work.

Conventionally, this kind of work was performed in each process by C1.
For example, the process is separated and unrelated to each other. For example, the product is temporarily stored in a temporary storage area near the tank using a crane, and then is temporarily stored in a temporary packaging storage area inside the tank side panel using a crawler crane, etc. They were unpacked and moved to construction sites divided by 4-chryso 1, etc., and then hoisted onto a crawler crane or the like and attached and fixed.

Therefore, each construction procedure is time-consuming and extremely inefficient, and especially in the process of unpacking at a temporary packaging storage area and lifting each membrane panel block one by one using a crawler crane. In the above-mentioned temporary packaging storage area, the membrane panel block temporarily placed in a substantially flat state is lifted up by a crawler crane, so that the membrane panel block is lifted from above the flat surface through an inclined state to a vertical state. It was unavoidable that bending stress would be applied.

That is, the membrane panel block is effective in terms of construction efficiency, and
The block is made as large as possible to avoid welding thermal stress during welding and joining in the subsequent process.
It has a considerable area and weight, and therefore, in the process of moving the membrane panel block from a horizontal board state to an inclined state to the above-mentioned lifting process, the lifting force acting on the upper end of the membrane panel block and its upper end In order to apply a large bending stress to the entire membrane panel block, particularly to the center of gravity, the membrane panel block is lifted and fixed to the side plate. However, it is difficult to correct the bending deformation when the side plate is attached, and it requires skill, and requires a lot of man-hours and danger. There is a problem with this.

In addition, when attaching and fixing the membrane panel block to the side plate, from the viewpoint of safety and convenience of post-processing, it is usual to include a process of attaching it from the upper side to the lower side.
However, in order to deal with the above-mentioned problem, a kite rail is installed around the upper end of the lateral root, a hoist crane is movably installed on the guide rail, and a gondola is suspended from the hoist crane via a wire]. Such technology has also been developed, but as mentioned above, the membrane panel block has a considerable size and weight, so the uppermost membrane panel block is lifted in a predetermined manner and the "C" side plate cold insulation material is placed in advance. Because the membrane panel block was too heavy to be fixed to the buried anchor hardware, the hoist crane needed to lift it was quite large. Panel 1
At the final stage of hoisting the membrane panel block, there was a problem in that the upper end of the membrane panel block interfered with the hoist crane, making it impossible to remove it.

Furthermore, interference between the gondola and the suspended membrane panel block cannot be avoided, and due to such technical constraints, the topmost membrane panel block must be fixed and covered with the cold insulation material on the side plate. The disadvantage was that it was extremely impossible.

Furthermore, from this point of view, it is unavoidable that each culm that attaches and fixes the membrane panel block to the side plate cold insulation material is extremely dangerous as mentioned above, and moreover, the number of panels is large and the process is numerous. Moreover, as the capacity of the tank increases, the risk increases.
was there.

Historically, membrane panels store low-temperature liquid directly on their inner surface, so not only the general surface, but also the corrugations and their surroundings must be precisely processed and maintained in their condition. However, in order to lift the membrane panel onto the inner surface of the cold insulation material of the side plate, conventional methods (31) A hanging piece such as a crawler crane or small ist crane is attached to the tip of the membrane panel.
As a result, the surrounding area may be deformed or (
There was a risk that the work would be damaged, and there was also a risk that it would interfere with operation after completion.

Therefore, as described above, for example, a guide rail is installed (a hoist crane is used to hoist the membrane panel block 1), and the gondola used for the operation is a membrane panel block as described above. Although it is a temporary structure, such as having guide rails running in two rows inside and outside to avoid interference between the two arms, the structure becomes complicated.
Moreover, it also had the disadvantage of high cost.

<Objective of the Invention> The object of the invention of this application is to solve the problem of (1λ As a technical problem to be solved, since the gondola is not lifted along the above-mentioned cold insulating material on the side plate, it is possible to create a bridge between the working floor and the side plate without interfering with the working floor of the +f?tlf gondola and the cold insulating material. The membrane panel block rises smoothly and the operation against the membrane panel block on the work floor is effectively accomplished. An excellent method of installing a membrane panel for a low-temperature tank that can be fixed in place and benefit the field of tank utilization in the soil energy industry, and @
It is necessary to provide the neck because it is a sign.

<Structure of the Invention> The structure of the invention of this application, which is based on the above-mentioned claims in accordance with the above-mentioned purpose, is that, in order to solve the above-mentioned problems, a group of membrane panel blocks manufactured in advance to a predetermined size in a factory are arranged in a predetermined manner. It is packed and transported to a temporary storage area above the base of the tank, where it is unpacked and installed one by one with a jig, etc., and a small ist crane with a guide rail is installed around the upper end of the side plate. etc., and the operation during that time is carried out by a work platform such as a gondola, which is also lowered from the sword rail so that it can be lowered in the R direction.
During this time, the membrane panel block to be lifted should be placed in a jig, etc., so that it does not interfere with or come into contact with the cold insulation material on the side panels or the work floor.
x PI Ll 'C The membrane panel block is of a considerable size so that its centering and temporary fixing to the anchor hardware immediately installed on the cold insulation material are performed in a specified manner depending on the work surface of the work floor. The work floor is −
Turn the work surface of the two-tier tray to the right, so that centering and temporary alignment work on the membrane panel block can be done safely.
In addition, spacers for forming a predetermined gap, which appears to be a cold insulator on the side plate, are installed on the work floor so that the membrane panel block and the mounting jig can be used without interference. Technical measures were taken to allow second elevation.

It should be noted that the embodiment of the invention of 19ri is of course not limited to the dual embodiment, and various embodiments can be adopted.

<Effects of the Invention> According to the invention of this application, basically one membrane panel block is clamped integrally with a jig and lifted along the side plate. Until the panel 10 and 11J side panels are insulated, and the gondola tongue is lifted up and placed in the designated position without touching or interfering with the work floor. The membrane panel is not susceptible to scratches or deformation due to any kind of interference. Therefore, after the tank is completed, there will be no deformed parts or cracks on the membrane panel, which is an excellent quality guarantee. 1q of trust
Not only is it effective, but it also does not cause damage to the work floor of cold insulation or Bon 1 spatula, etc., and makes temporary equipment durable and has enough capacity to be used for the next construction. It can be done (Ω).

Therefore, on the work floor of the gondola, etc., a specified space or gap should be created between the side plate and the cold insulation side of the side plate, and this should be maintained. Since this is possible, the above-mentioned effect of allowing the relative passage of the fixed f=J jig to the ('lX floor) is produced.

Therefore, in order to actively create a space or gap for the membrane panel block to pass between the C1 work floor and the cold side of the side plate, there are There is also the effect that there is a degree of freedom in the installation position and that the installation h1 of the hanging deck 1 becomes easier.

In addition, by hanging the work floor in two levels, the work space can be taken up vertically, so the thickness can be made relatively small, and it is therefore possible to reduce the thickness of the work floor. As a result, the membrane panel block can be raised and lowered in a vertical position while avoiding obstacles such as the pump barrel, and the membrane panel block can be lifted up and down in a 1:1j position.
It is possible to move the gondola through the rails in the direction of the pump barrel and lower the working floor of the gondola between the pump barrel and the cold storage area on the side plate, and also to install a membrane panel between the work floor and the side plate 1” I passed through the ivy relatively! 'r t), the excellent effect of being able to perform the work sufficiently and perform the operations related to the work will last for a long time.

Furthermore, in order to be able to form and cover a sufficient space between the work floor and the side roots, when attaching and fixing a membrane panel block between the pump barrel and the side plate, An excellent effect is achieved in that the next membrane panel block can be passed with a space between the inner surface of the membrane panel block and the work floor, making work easier.
