Abstract
A steel plate basement skiing diving platform slideway snow fixing net drawknot plate fixing structure belongs to the technical field of snow sports item infrastructure construction. The method comprises the following steps: the device comprises a steel plate substrate, a hydrophobic plate, a snow fixing net drawknot plate, a stainless steel internal thread sleeve, a welding seam, a slotted flat end set screw, a large hexagon nut and a spring washer; the snow net pulling plate is arranged on the slotted flat end fastening screw and is fixed by a large hexagon nut matched with a spring washer. The fixing device has the advantages of effectively solving the difficult problem of fixing the snow fixing net on the steel plate substrate and realizing the fixing of the pull plate of the snow fixing net of the steel plate substrate slideway on the snowfield with the all-steel structure.
Description
Technical Field
The utility model belongs to the technical field of snow sport item infrastructure construction, a solid snow net drawknot board fixed knot of steel sheet basement skiing diving platform slide constructs is provided very much, is applicable to and fixes based on solid snow net drawknot board of steel sheet slide basement.
Background
The city skiing big diving tower for undertaking winter Olympic Games is the only formal snow competition venue in the main city area of Beijing of winter Olympic Games and is also a skiing big diving tower venue permanently reserved at the head of the world. In the past, most of ski jumps are made on natural mountains by shaping and then directly snow on the mountains, and snow-fixing nets are fixed on the natural mountains in an anchoring mode. The main structure of the skiing diving platform in the main city area of Beijing is an all-steel structure, the base of the track is a steel plate, and how to fix the snow fixing net on the steel plate is a brand-new challenge.
Disclosure of Invention
An object of the utility model is to provide a snow net drawknot board fixed knot board is fixed to steel sheet basement skiing diving platform slide has effectively solved the steel sheet basement and has carried out the fixed difficult problem of snow net admittedly, has realized the snow of project steel sheet basement slide on the all steel construction snow and has fixed of snow net drawknot board. The fixing device is suitable for fixing the snow fixing net drawknot plate based on the steel plate substrate slideway.
The utility model discloses a bore the through-hole on the steel sheet basement, then with the welding of stainless steel internal thread sleeve in the steel sheet basement, will open a slot flat end holding screw in the stainless steel internal thread sleeve, it will solidify snow net drawknot board again and install on the screw fixedly with big hexagon nut unstrained spirits spring washer to have laid the hydrophobic plate. The method solves the difficult problem of fixing the snow fixing net on the steel plate substrate, and realizes the fixation of the pull plate of the snow fixing net on the steel plate substrate slideway of the all-steel snowfield project.
The utility model discloses a: the snow-fixing net comprises a steel plate substrate 1, a drainage plate 2, a snow-fixing net drawknot plate 3, a stainless steel internal thread sleeve 4, a welding seam 5, a slotted flat end fastening screw 6, a large hexagon nut 7 and a spring washer 8; drilling a through hole on the steel plate substrate 1 and chamfering the upper edge of the hole, wherein the stainless steel internal thread sleeve 4 penetrates into the drilled through hole on the steel plate substrate 1, aligns with the upper surface of the steel plate and is fixed by welding seams 5 in a surrounding welding way, so that a firm whole is formed; the slotted flat-end set screw 6 is screwed into the stainless steel internal thread sleeve 4, the hydrophobic plate 2 is laid on the steel plate substrate 1, and the snow-fixing net drawknot plate 3 is arranged on the slotted flat-end set screw 6 and is fixed by a large hexagon nut 7 and a spring washer 8.
The slotted plain end set screw 6 is screwed into the stainless steel internal thread sleeve 4, the snow fixing net drawknot plate 3 is installed on the slotted plain end set screw 6 and is fixed by a large hexagon nut 7 matched with a spring washer 8, and the fixing problem of the snow fixing net drawknot plate is realized through the matching switching of the internal thread sleeve and the screw, so that the snow fixing net drawknot plate on the steel plate substrate is firmly fixed.
1. A through hole is drilled in the steel plate substrate 1 and chamfered at the upper edge of the hole.
2. And (3) penetrating the stainless steel internal thread sleeve 4 into the drilled through hole on the steel plate substrate 1, aligning the upper end with the upper surface of the steel plate and fixing by welding seams 5 in a surrounding welding way.
3. The slotted flat set screw 6 is screwed into the stainless steel internally threaded sleeve 4.
4. Laying the hydrophobic plate 2.
5. The snow-fixing net drawknot plate 3 is arranged on a slotted flat-end set screw 6 and is fixed by a large hexagon nut 7 and a spring washer 8.
