Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waste gas boiler and a method for constructing a 9P gas frame 2.

When installing multiple chimneys and independent waste gas boilers 2 for multiple generation #IL equipment, as shown in Figure @1, construct a steel tower 2 to prevent the transfer of the exhaust gas 1 and this quotient. Boiler 3 was installed adjacent to steel tower 2, but the site was narrow and the space was limited. In many cases, it is extremely difficult to secure them. Since there is a support post 3a of the boiler around the lower hopper of the boiler, it is difficult to maintain the boiler while wearing a hakama.

This invention was proposed in view of #1 above, and allows the waste gas boiler and the exhaust stack frame (exhaust stack and cylinder 2) to be installed horizontally in a small space, and also allows for easy maintenance of the boiler. Is there a construction method that is easy to work with? The purpose is to provide.

Hereinafter, the fruits of this invention will be explained with reference to two drawings.

Figures 2 to 71 (i) The method of the present invention is shown in μ-order.

(1) First, the common frame 42 is constructed on the site where the exhaust stack 9 in FIG. 2 is planned to be constructed. This construction is joint J1!
1. The structural members are hoisted to a predetermined height of 1K using a crane, and assembled using reshaping bolts.

(2) Two horizontal lift frames 16 (see FIG. 9) are mounted on the upper part of the common A frame 4, and a jacking device 53 is fixed to the horizontal lift members 16. This shirt? The device d5 is the thirteenth
As shown in the figure, the hydraulic cylinder 6. hydraulic piston 10
1 Chou Miyako Ratchet 11. The VC consists of an upper ratchet 12 and a rod 7, and supplies pressure oil from a hydraulic bonder (not shown) to a hydraulic chamber 6a constituted by a hydraulic cylinder 6 and a hydraulic piston 10 from the state shown in FIG. Hydraulic piston 10ε is pushed up, oil) The rod 7 is pushed up via the upper ratchet 122 which is freely attached to the convex part of -E of the upper piston 10. '
+”c ?tll It is attached freely to the protrusion at the bottom of the pressure cylinder/cylinder 6, and it will naturally come off from the notch made in the ratchet 11110 of the F part 7, but the hydraulic piston will be removed by one pitch of the notch. 10 lifts, the lower ratchet 11 engages the next stroke of the rod 7.

In this state, when the oil in the hydraulic chamber 6a is drained, the rod 7 becomes F
As the hydraulic piston 10 descends F while remaining fixed from the ratchet IIK, the upper ratchet 12 naturally comes off from the notch cut into the rod 7, and the hydraulic piston 10 descends to near the bottom. At this time, from the N4 return of this operation, which will be engaged in the next insertion,
Rod 72 must be lifted by J, ¥.

(3) Next, the exhaust direction with respect to the top V] 3. Steel tower block a, human movement/1 spill prevention bet 142, common rack lI44, brought in with clay 74 and assembled. Normal Lido-A cylinder 13
and steel tower block alJ, 1. It slides in the J2F direction, but at this time the exhaust pipe 13 and the steel tower block a are temporarily fixed.

(4) Next, grip the exhaust pipe 13 with the gripping mechanism 9 fixed to the rod 7 of the jack k+it 5, operate the hydraulic jack 63 as described above to raise the rod 7, and lift the exhaust pipe 13 and the tower block a. Pull up.

(5) The exhaust pipe 13 is a short steel pipe with a length of, for example, about 3 m.

The first connection is made by connecting the exhaust iFi 13 and the tower block 11 as shown in FIG.

When the convex β portion of the tower block a of the circle IJ8 is completed, the ) and M of Tanmiya 13a are completed, and the steel tower block b is fitted with a crane and the steel tower Zoroku is connected with the U6 long bolt.
Do t. /j Oh, each steel tower block is moved 2 minutes from side to side, and fitted into the exhaust tt413 from the left and right (4 times).Next, as in the process of FllI^pi (4),
Jatu I--loaded trout 5 with exhaust ii'j 13 and tower block a.

bε Lift associate f) Short t13” E!>g.

At this time, OP-1 #13 and the steel tower block (J) are temporarily fixed as mentioned above.

(7) Repeat the above steps to connect the steel tower Zoroku C (on this -A side) (one day is 41 blocks (this is the base for forming N) ε) above the lowest one, and Exhaust pipe 132
5) As shown in the figure, there is an auxiliary material (shown by hatching in the figure to distinguish it from the exhaust pipe) at the lower end of the h-cylinder 13. By raising this auxiliary material 18E jack HIk5,
The bottom two of JjF Qihei 13] Origin (Lift up to the top of 144).

(81, then the 8th and 9th floors are attached to the top of the common 4 on the east 19th floor, and the base play 117 is installed on top of it.
E is fixed, and the exhaust pipe 132 is placed on this base plate 17 and fixed.

(9) Next, lift the lowest steel tower block d using a crane or the like, fit it into the exhaust pipe 13 from the left and right, connect the upper steel tower block CK to the upper end, and fix it to the upper part of the common frame 4. Next, the auxiliary member 182 is removed.

(10) After fixing the steel tower, attach a chain block 20 etc. to the upper part of the common frame 4, lift the upper hopper 21aE of the boiler 21 with this chain block 20, and then use the boiler main body 21b2 rollers etc. 10, into the common frame 4, and pulled it up by the jacking device 5 to a predetermined position.
As shown in Figure 1, pull out the rotary bracket 242 which has been torn off with a pin/23 from the D2 frame beam 22, and connect the mounting member 25 fixed to the boiler body 21b and the rotary bracket 24 with high tension bolts. Then, the boiler main body 21b is installed on the D2 frame beam 22.

(11) Next, pull up the "F" section hopper 21C2 of the boiler 221 and connect it to the boiler main body 21b.

(12) Once all the above work is completed, the jacking device 5, checks/blocks, etc. will be removed, and the construction of the steel tower and exhaust stack 13 and the installation of the boiler 21 will be completed.

As explained above, the present invention provides a common frame equipped with the jacking device 1. The cylinder frame (exhaust stack and steel tower) 2 is assembled sequentially from the top of the cylinder frame (exhaust stack and steel tower) 2 within this common frame and raised by the above-mentioned cypress equipment to construct the exhaust stack WE on the common frame. Unlike the conventional method of installing the boiler body 2 adjacent to the exhaust tower frame, the two boiler bodies can be constructed in a narrow space. Since there is no need for supporting columns around the boiler, sufficient work space 2 can be secured, making it easy to perform maintenance work on the boiler. Since the assembly work of the LA cylinder frame is carried out in a common frame, there is no need to work at heights, making it efficient and easy for all women to work on. Also, the common A frame is the exhaust stack frame and the boiler, both 2[! Although there is a peace of mind that the cross section of this common frame will be increased by 2 in terms of strength, the total cost will be lower than in the conventional case where the boiler E14 area is separately constructed and installed. Become a VC. Zara VC
By providing a rotary platen and installing the boiler body on it, the boiler support structure becomes simple and the installation is efficient. It is.
