Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments. It is to be understood that the following description is only for purposes of clearly illustrating the present invention and is not to be taken in a limiting sense.
A manufacturing and construction method of a coke oven flue bent pipe support frame is implemented by the following steps:
s1, manufacturing a support frame: as shown in fig. 2 and fig. 3, the support frame is manufactured according to the actual size of the flue elbow, two longitudinal beams 1 arranged in parallel and back to back and a plurality of cross beams 2 vertically arranged between the two longitudinal beams 1 are welded to form a ladder-type structure, the longitudinal beams 1 and the cross beams 2 respectively adopt angle steel with the specification of & lt 50 x 5, wherein the cross beams 2 and the longitudinal beams 1 form a plurality of flue elbow spaces 5 for supporting the flue elbow 4, and each pair of cross beams forming the flue elbow spaces 5 are arranged in back to back.
The longitudinal beam interval and the cross beam interval of each flue bent pipe blank 5 are equal, the interval is larger than the diameter of a flue bent pipe body, the flue bent pipe can conveniently and smoothly pass through, and meanwhile, the interval is smaller than the diameter of the picking edge at the top of the flue bent pipe, so that the flue bent pipe can be finally clamped on the support frame 6. The whole supporting frame formed by the longitudinal beams 1 and the cross beams 2 plays a role in supporting the flue elbow.
S2, mounting a support frame: after the binding of the upper layer steel mesh sheets of the flue top plate is finished, the support frame can be installed; during installation, because the longitudinal center line 7 of the flue elbow and the longitudinal center line 8 of the flue are a set distance, the installation position of the flue elbow 4 is determined according to the longitudinal center line of the flue, the installation position of the support frame 6 is determined according to the transverse center line of the flue elbow, and then the support frame 6 is directly fixed on the reinforcing mesh sheet on the upper layer of the flue top plate.
S3, reinforcing the support frame: after the support frame 6 is installed in place, reinforcing the support frame 6 by taking each flue bent pipe blank 5 on the support frame 6 as a unit, as shown in fig. 4, welding the upper end of a vertical reinforcing rib 9 on a longitudinal beam 1 of the support frame on one side of the support frame 6 close to a longitudinal central line 8 of a flue, fixing the lower end of the vertical reinforcing rib to an arch bottom template 11 through a base 10 welded below the vertical reinforcing rib, wherein the vertical reinforcing rib 9 is made of reinforcing steel bar waste with the diameter of more than 20mm, and the base 10 is an iron plate with the diameter of 50 multiplied by 5mm, so that the vertical reinforcing rib 9 is prevented from being directly contacted with the arch; and one side of the support frame 6, which is far away from the longitudinal central line 8 of the flue, is fixedly welded with the support frame 6 and the vertical wall reinforcing steel bars 12 of the flue, so that the vertical support effect on the two sides of the support frame is realized.
S4, mounting a flue bent pipe: the flue bent pipe 6 penetrates through the flue bent pipe blank 5 and then is installed at a specified position, and the top edge of the flue bent pipe is clamped on the supporting frame 6, so that the supporting effect of the supporting frame 6 on the flue bent pipe 6 is realized.
S5, pouring concrete: and pouring the support frame 6 and the flue bent pipe 6 together to form a concrete entity to complete the support and installation of the flue bent pipe 4.
In the method, the material of the support frame is lightened, so that the material usage amount is reduced, the cost is greatly reduced, and the construction cost can be reduced by more than ten thousand yuan for each coke oven. The support frame adopted in the construction process is simple in structure and convenient to manufacture and install, the material of the support frame can be buried pipe support technical measures of a coke oven top plate and civil engineering reinforcing steel bar waste, and when the support frame is applied to other projects, the support frame can be manufactured by fully utilizing the existing material of a construction site according to local conditions, so that the purpose of saving cost is achieved. Therefore, the invention has good popularization and application prospects.
The foregoing is only a preferred embodiment of the present invention. Various modifications and equivalent changes may be made by those skilled in the art without departing from the spirit and scope of the present invention, and such modifications and changes are intended to be included within the scope of the present invention.
