Abstract
The utility model relates to hot air duct, particularly relates to a kind of hot air duct and builds device by laying bricks or stones.A kind of hot air duct upper part masonry arch tire, it comprises the long strip shape arch tire plate of cross section and hot air duct upper part radian coupling, bottom arch tire plate, two ends straining beam plate connects, it also comprises being positioned at encircles the back up pad that tire plate bottom is provided with radial direction, and back up pad top is connected with encircleing bottom tire plate by stiffening plate.The utility model, mismachining tolerance is little, and therefore circular arc degree is relatively good, and masonry quality significantly improves.
Description
Technical field
The utility model relates to hot air duct, particularly relates to a kind of hot air duct and builds device by laying bricks or stones.
Background technology
Hot air duct is the unique channel connecting hotblast stove and iron-smelting blast furnace, it is the important component part of iron-smelting blast furnace, after production for some time, due to the pipeline more high reason of temperature in process of production, often there is the phenomenons such as hot air duct burning is red, burn in these hot air ducts.Cause gas leak to produce potential safety hazard, must process in time.Hot air duct, when building process again, first sprays, then builds lower semi-ring by laying bricks or stones, then build semi-ring by laying bricks or stones.Concrete way is: first lower part has been built by laying bricks or stones (first building heat insulation layer, then build working lining by laying bricks or stones), then built upper part by laying bricks or stones, it is difficult point that upper part is built by laying bricks or stones, and general employing bamboo cane is bending to be supported below, then builds by laying bricks or stones above, due to bamboo cane discontinuity, therefore circular arc degree is difficult to ensure.Building process should ensure brickwork joint, considers the requirement of circular arc degree again, otherwise conjunction tweel block is difficult to build by laying bricks or stones, and to processing brick, increase workload virtually, build by laying bricks or stones and extremely waste time and energy, masonry quality is poor simultaneously; Build difficulty by laying bricks or stones in junctions and manhole position larger, only have small part to build veteran master craftsman by laying bricks or stones and just can complete reluctantly and build by laying bricks or stones.For blast furnace overhaul, when hot air duct is built by laying bricks or stones again, will consume a large amount of time and labor force in upper semi-ring building process, labour intensity is very large simultaneously.
Prior art carries out hot air duct when building by laying bricks or stones, bamboo cane discontinuity, and different bamboo cane toughness is different, the circular arc degree of therefore building by laying bricks or stones, surface finish and brickwork joint are difficult to reach construction requirement, long-time adjustment is not only consuming time, and construction error is large, higher to workmen's skill set requirements, because workmen's state of the art is different, build upper part time error by laying bricks or stones very large, mainly setting circle radian is come to bamboo cane processing, time is long, and partial arc degree can not meet pipeline builds specification technique requirement by laying bricks or stones, and part small transfer line location is poorer, because setting circle radian error is very large, construction requirement cannot be reached.Will consume a large amount of time and labor force in bamboo cane position fixing process, to build effect by laying bricks or stones bad simultaneously.Utilize now hot air duct upper part to build special tool (arch tire) location by laying bricks or stones, build by laying bricks or stones.Only arch tire need be located, circular arc degree just has very high positioning precision, build by laying bricks or stones just convenient and swift, general workmen has also been easy to, and does not need the workmen of very hi-tech level, more can not be different because of workmen, build error variance by laying bricks or stones large, this cover hot air duct upper part is built special tool (arch tire) by laying bricks or stones and is built by laying bricks or stones to hot air duct, provides a kind of method of quick, easy and low cost, and simple to operation.
Summary of the invention
The utility model is intended to the defect overcoming prior art, provides a kind of hot air duct upper part masonry arch tire.The utility model, mismachining tolerance is little, and therefore circular arc degree is relatively good, and masonry quality improves greatly, and the utility model is easy to use, and simply, work of building by laying bricks or stones used all can use.
In order to solve the problems of the technologies described above, a kind of hot air duct upper part masonry arch tire, it comprises the long strip shape arch tire plate of cross section and hot air duct upper part radian coupling, bottom arch tire plate, two ends straining beam plate connects, it also comprises being positioned at encircles the back up pad that tire plate bottom is provided with radial direction, and back up pad top is connected with encircleing bottom tire plate by stiffening plate.
Described a kind of hot air duct upper part masonry arch tire, described arch tire plate upper surface is provided with arch tire bar.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the utility model schematic cross-section.
Embodiment
Fig. 1 is an embodiment of the present utility model, visible in figure, a kind of hot air duct upper part masonry arch tire, it comprises the long strip shape arch tire plate 1 of cross section and hot air duct upper part radian coupling, be semicircle in figure, bottom arch tire plate, two ends straining beam plate 2 connects, and it also comprises being positioned at encircles the back up pad 3 that tire plate bottom is provided with radial direction, and back up pad top is connected with encircleing bottom tire plate by stiffening plate 4.
Described a kind of hot air duct upper part masonry arch tire, described arch tire plate upper surface is provided with arch tire bar 5.
Above-described embodiment is only used for the utility model being described and should not be construed restriction of the present utility model.Those of ordinary skill in the art, after having read specification sheets, can make the change on various forms to the utility model, these changes are all by scope claimed for the claims falling into the application.
Claims (2)
1. hot air duct upper part masonry arch tire, it comprises the long strip shape arch tire plate of cross section and hot air duct upper part radian coupling, bottom arch tire plate, two ends straining beam plate connects, it is characterized in that, it also comprises being positioned at encircles the back up pad that tire plate bottom is provided with radial direction, and back up pad top is connected with encircleing bottom tire plate by stiffening plate.
