Description

[Detailed description of the invention] [Industrial application field] This invention relates to a frame for assembling steel plate cells constituting sea walls, embankments, etc.

[Problem that the invention attempts to solve]

One method of assembling steel plate cells in large cylindrical steel structures is the vertical block construction method, which involves assembling a plurality of vertically divided blocks.
In this case, several concrete blocks or rectangular sleepers are arranged in a circle according to the diameter of the steel plate cell, and the divided blocks of the steel plate cell are successively erected using this as a frame (see Fig. 19). However, with this method, it is difficult to adjust the heights of the frames, and it takes a considerable amount of time to position the divided blocks during erection. Furthermore, even after the dividing block is placed on the pedestal, it is difficult to finely adjust the position of the dividing block in either the circumferential direction or the radial direction of the steel plate cell due to the large frictional force acting between the pedestal and the block. As a result, it takes a long time to assemble the steel plate cells.

This invention improves the above-mentioned conventional problems and develops an assembly frame that speeds up the assembly work of steel plate cells using the vertical block construction method.

[Structure of the idea and its implementation examples]

The gist of this invention is as described in the claim section of the above-mentioned utility model registration, and it has an I-shaped or box-shaped cross section by welding or bolting steel materials such as section steel, and has a steel plate cell. an annular structure having approximately the same diameter; a pair of erection guide plates that are movable in the radial direction of the annular structure; It consists of a roller.

The details will be explained below with reference to illustrated embodiments.

1, 2 and 3, the assembly frame of this invention consists of an annular structure 1, a guide plate 2 for erection, and a roller 3. Note that A is a divided block to be assembled into a steel plate cell.

The annular structure 1 has approximately the same diameter as the steel plate cell assembled by welding or bolting steel sections such as H-shaped steel and channel steel, and supports the steel plate cell, and is I-shaped or box-shaped. It has a cross section. Note that 4 is a stiffener.

The erection guide plates 2 are arranged in a pair facing each other at a required interval on the upper surface of the annular structure 1, and are used to sandwich the steel plate cells, and have slits 6 in the bottom plate 5 and the upper surface of the annular structure, respectively. , can be fixed with a fastening bolt 7 and can be moved in the radial direction of the annular structure. 8 is a stiffener, 9 is a reaction plate, and 10 is a hydraulic jack.

The rollers 3 are supported by brackets 11 projecting from both sides of the upper surface of the annular structure 1, and are positioned in large numbers at required intervals so as to slide the steel plate cells in the circumferential direction of the annular structure.

[Effect of invention]

The use of the above assembly frame will be explained. First, the divided block A is erected between a pair of opposing guide plates 2 using a crane or the like. In order to facilitate installation, the guide plates 2 have different heights inside and outside, and at least two sets are used for each divided block.

Next, the position of the divided block installed between the guide plates is adjusted, but since the horizontal movement in the circumferential direction is done via the rolls on the annular structure 1, the divided block A is This can be done easily by attaching and towing it. Horizontal movement in the radial direction can be easily performed by pushing the guide plate 2 by operating the hydraulic jack 10 located between the guide plate 2 and the reaction plate 9. Then, the guide plates 2 are positioned by operating the fastening bolts 7, and the divided blocks A are held between the guide plates 2. The hydraulic jack 10 is provided on the opposite side to the one shown in the figure or on the other side, and operates either or both of the opposing guide plates 2 as appropriate.

Next, the next divided block is erected by the same operation, and the adjacent divided blocks are connected by welding to complete the steel plate cell, and the guide plate 2 is loosened and carried out.

[Effect of idea]

This invention has the above-mentioned configuration, and since the pedestal is an integral annular structure, installation and height adjustment of the pedestal are easy. In addition, the position of the divided blocks built on the frame can be easily fine-tuned in both the circumferential and radial directions, and is held in place, making welding work easy and reliable. It is possible to speed up the assembly work.
