The syndeton of electrolyzer supporting beam and buttress
Technical field
The utility model relates to a kind of syndeton of bearing base, the syndeton of particularly a kind of electrolyzer supporting beam and buttress.
Background technology
Initial electrolyzer basis buttress is in order to solve the Insulation Problems between electrolyzer and the earth, be that 500mm with electrolyzer basis buttress topmost makes plain concrete (promptly not adding reinforcing bar), existing large-scale pre-baked cell temperature in start-up course is very high, the arch camber distortion can take place in supporting beam, to produce very big horizontal force to buttress after the supporting beam arch camber, plain concrete is easy to by drawing crack like this, the electrolyzer buttress appears in the actual engineering often by the accident of drawing crack, for addressing this problem, be that the buttress reinforcing bar is fitted on the buttress top from substrate always at present, and add insulation layer on buttress top, can prevent that like this buttress is by drawing crack.Though this way has solved buttress by the problem of drawing crack, but in the production start-up course, after the supporting beam arch camber bearing is still had very big horizontal force, the reinforcing bar that the buttress sectional dimension need strengthen and dispose is a lot, so not only can increase quantities, prolong the duration, but also can cause the increase of construction costs.Also having a kind of method is exactly to add a single-arc shaped board support such as Fig. 3 in the middle of insulcrete and supporting beam, though can reduce supporting beam to the horizontal force that buttress produces, reduces the sectional dimension and the quantity of reinforcement of buttress, and single-arc shaped board support stability is bad.
The utility model content
Technical problem to be solved in the utility model is, the syndeton of a kind of electrolyzer supporting beam and buttress is provided, this syndeton not only can reduce supporting beam to the horizontal force that buttress produces, and reduces the sectional dimension and the quantity of reinforcement of buttress, and this syndeton has excellent stability.
The technical solution of the utility model: in order to solve the problems of the technologies described above, the syndeton of electrolyzer supporting beam of the present utility model and buttress, comprise the electrolyzer supporting beam, the lower end of electrolyzer supporting beam is connected with the arc bearing, the arc bearing is installed on the buttress of electrolyzer basis by insulcrete, and the arc bearing is two curved plates arranged side by side.
The arc tips of arc bearing is connected with the lower end of electrolyzer supporting beam.
Between insulcrete and arc bearing, also be provided with the bearing steel plate, further increase rigidity, prevent the insulcrete cracking, the rectilinear end welding of bearing steel plate and arc bearing.
Compared with prior art, the utility model adds a two arc bearing in the middle of insulcrete and supporting beam, it allows supporting beam that the displacement of horizontal direction is arranged, therefore can reduce the arch camber distortion of supporting beam to a great extent, finally reach the horizontal force that reduces the basis, prevent the buttress cracking, can reduce the sectional dimension and the quantity of reinforcement of buttress, and making and easy for installation, good stability.

Embodiment
Embodiment 1 of the present utility model: the syndeton of electrolyzer supporting beam of the present utility model and buttress, comprise electrolyzer supporting beam 1, the lower end of electrolyzer supporting beam 1 is connected with arc bearing 2 in turn, bearing steel plate 3, insulcrete 4 and electrolyzer basis buttress 5, arc bearing 2 is two curved plates arranged side by side, as shown in Figure 1, only be different from the prior art that Fig. 3 represents the structure that a curved plate forms arc bearing 2.
The upper end of arc bearing 2, promptly arc tips is connected with the lower end of electrolyzer supporting beam 1, and the rectilinear end of lower end is welded on the bearing steel plate 3.See Fig. 2.
