Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In description of the present utility model, it will be appreciated that, term " transverse direction ", " length ", " width ", " thickness ", " on ", D score, " front ", " afterwards ", " vertically ", " top ", " end " " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In addition, term " first ", " second " etc. only for describing object, and can not be interpreted as instruction or hint relative importance or imply the quantity indicating indicated technical characteristic.Thus, one or more these features can be expressed or impliedly be comprised to the feature being limited with " first ", " second " etc.In description of the present utility model, the implication of " multiple " is two or more, unless otherwise expressly limited specifically.
See Fig. 1 to Fig. 3, a kind of chimney top operating platform, comprises chimney and the operating platform arranging chimney top; Operating platform comprises the little ring beam of platform, the large ring beam of platform, multiple support level bar, protective plate and multiple railing post in chimney end face.
The little ring beam of platform and the large ring beam of platform are circular configuration, and, the little ring beam of platform and the large ring beam of platform are centered around the outside of chimney top respectively centered by chimney, the little ring beam of platform is less than the distance of the large ring beam of platform apart from chimney top lateral wall apart from the distance of chimney top lateral wall, namely the little ring beam of platform, the large ring beam of platform and chimney are coaxial, and the diameter of the little ring beam of platform is less than the diameter of the large ring beam of platform.
Every root support level bar is horizontally disposed with, one end of support level bar is fixed on the lateral wall of chimney top, the bottom of the little ring beam of platform is fixedly connected with every root support level bar, particularly, the bottom of the little ring beam of platform is fixedly connected in the middle part of support level bar to the part away from chimney lateral wall, the bottom of the large ring beam of platform is fixedly connected with the other end of every root support level bar, the i.e. end away from chimney of every root support level bar, thus make the little ring beam of platform and the large ring beam of platform be arranged on the outside of chimney top by many support level bars.The central angle that adjacent two support level pole pairs are answered is 30 °.Conveniently little for platform ring beam and the large ring beam of platform are fixed on support level bar, the cross section of the little ring beam of platform and the large ring beam of platform is " L " type, the part of its level is welded with support level bar, and this makes the contact area of coupling part large, thus connects more firm.
In order to be fixed on the lateral wall of chimney by support level bar better, preferably also comprise upper bracket plate, support level bar is fixed on the lateral wall of chimney top by upper bracket plate and the first expansion bolt near one end of chimney.When support level bar is to lower stress, whole upper bracket plate for disperseing downward pressure, thus makes the connection of the lateral wall of support level bar and chimney more firm.In order to play the connectivity robustness of reinforced support horizon bar and chimney top lateral wall further, gusset can also be provided with between upper bracket plate and support level bar, thus make upper bracket plate, gusset and support level bar form the most stable stressed triangle.
In order to improve the weight capacity of support level bar, a support diagonal brace can also be thereunder set, support diagonal brace is inclined relative to horizontal setting, its inclination angle is preferably at 45 °-50 °, the too large or too little support effect that all can affect support diagonal brace in inclination angle, 45 ° of-50 ° of optimums, the upper end of support diagonal brace is connected with the end winding support of support level bar away from chimney, preferably adopt welding, the lower end of support diagonal brace is fixedly connected with the lateral wall of chimney.In order to the bonding strength of the lower end and chimney of improving support diagonal brace, lower support plate can also be comprised, the lower end of support diagonal brace is fixed on the lateral wall of chimney by lower support plate and the second expansion bolt, when support level bar is to lower stress, support diagonal brace is also subject to downward power, whole lower support plate can be used for disperseing downward pressure, thus makes the connection of the lateral wall of support diagonal brace and chimney more firm.
Multiple railing post is vertically arranged, and the bottom of each column is fixed on every root support level bar accordingly away from the end of chimney; The top of railing post is provided with accommodation rail; Conveniently accommodation rail is connected to securely the top of railing post, the cross section of accommodation rail is inverted "L" shaped, the part of this accommodation rail level and the welded top of railing post, the sidewall weld of the vertical part of accommodation rail and railing post, bonding strength is higher.Adjacent two railing posts are fixedly connected with the railing cross bar of horizontally set, many railing cross bars join end to end formation circular configuration; The cross section of railing cross bar is also " L " type, and its vertical part is welded on the lateral surface of railing post.During concrete enforcement, adjacent two railing posts of short transverse can arrange multiple railing cross bar, and the multiple railing cross bars being positioned at sustained height join end to end and form circular configuration respectively.
In described chimney end face, protective plate is arranged in chimney, and in chimney end face, protective plate upper side is provided with cross reinforcement, protective plate and inner wall of stack tight fit in chimney end face.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
