Detailed description of the invention
A kind of return air shafts of anticracking, comprise cylindrical shape air-return vertical shaft 1 and wind cave 2, cylindrical shape air-return vertical shaft 1 is provided with wind cave connector 3, be provided with fore shaft collar tie beam on taper shape in the barrel of the cylindrical shape air-return vertical shaft 1 above wind cave connector 3 and strengthen cage 4, on taper shape, cage 4 strengthened by fore shaft collar tie beam is by upper interior collar tie beam muscle 5, upper cycle beam muscle 6 and upper reducing collar tie beam right-angled trapezium dowel 7 form, be provided with turbination in the barrel of the cylindrical shape air-return vertical shaft 1 of the below of wind cave connector 3 under, cage 8 strengthened by fore shaft collar tie beam, under turbination, cage 8 strengthened by fore shaft collar tie beam is by lower interior collar tie beam muscle 9, lower cycle beam muscle 10 and lower reducing collar tie beam right-angled trapezium dowel 11 form, in the barrel of the cylindrical shape air-return vertical shaft 1 of the front side of wind cave connector 3, be provided with front column strengthen cage 12, it is by front outside stud 14 that front column strengthens cage 12, front inner side stud 15 and front right-angled trapezium horizontal loop muscle 16 form, in the barrel of the cylindrical shape air-return vertical shaft 1 of the rear side of wind cave connector 3, be provided with rear column strengthen cage 13, it is by rear outside stud 17 that rear column strengthens cage 13, rear inner side stud 18 and rear right-angled trapezium horizontal loop muscle 19 form.
In upper, collar tie beam muscle 5 is 5, and upper cycle beam muscle 6 is 3, and lower interior collar tie beam muscle 9 is 3, and lower cycle beam muscle 10 is 5, and front outside stud 14 and rear outside stud 17 are 5, and front inner side stud 15 and rear inner side stud 18 are 3.
On taper shape of the present invention, fore shaft collar tie beam is strengthened cage 4 and also be can be described as the dark girder construction in top, and it adopts No. 20 galvanized wire colligations to form by 3 inner side φ 18 screw-thread steels of spacing 200 millimeters and 5 outside φ 18 screw-thread steels of spacing 200 millimeters and the screw-thread steel of 1 φ 12.Under turbination of the present invention, fore shaft collar tie beam is strengthened cage 8 and also be can be described as the dark girder construction in bottom, and it adopts No. 20 galvanized wire colligations to form by 5 inner side φ 18 screw-thread steels of spacing 200 millimeters and 3 outside φ 18 screw-thread steels of spacing 200 millimeters and the screw-thread steel of 1 φ 12.
