Abstract
A concrete basement skiing diving platform slideway snow fixing net drawknot plate mounting and fixing structure belongs to the technical field of snow sports project infrastructure construction. The snow-fixing net comprises a concrete substrate, a hydrophobic plate, a snow-fixing net drawknot plate, a stainless steel internal thread sleeve, an anchoring adhesive, a slotted flat-end set screw, a large hexagon nut and a spring washer; drilling a through hole on a concrete substrate, injecting anchoring adhesive into the through hole, implanting a stainless steel internal thread sleeve into the through hole on the concrete substrate with the injected anchoring adhesive, fixing the stainless steel internal thread sleeve on the concrete substrate, screwing a slotted flat end fastening screw into the stainless steel internal thread sleeve, laying a hydrophobic plate on the concrete substrate, and installing a snow fixing net drawknot plate on the slotted flat end fastening screw and fixing the snow fixing net drawknot plate by using a large hexagon nut unstrained grain spring washer. Has the advantages that: the method has the advantages of novel structure, safety, reliability and high assembly degree, solves the difficult problem of fixing the snow fixing net on the concrete base, and realizes the fixation of the snow fixing net drawknot plate of the concrete base slideway of the snowboarding project.
Description
Technical Field
The utility model belongs to the technical field of snow sport item infrastructure construction, a concrete basement skiing diving platform slide is solid snow net drawknot board installation fixed knot and is constructed is provided very much, is applicable to and is based on concrete slide basement solid snow net drawknot board fixed method.
Background
Beijing was successful in applying for Olympic Games in winter 2022, the skiing big jumping stand is the only formal competition venue on snow in the main city area of Beijing city of Olympic Games in winter 2022, and is also a skiing big jumping stand 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 body structure of the first steel skiing big diving platform is an all-steel structure, the foundation of the local track in the landing area is concrete, and the brand-new challenge of how to fix the snow fixing net on the concrete is faced.
Disclosure of Invention
An object of the utility model is to provide a concrete basement skiing diving tower slide is snow net drawknot board fixed knot structure admittedly has solved the concrete basement and has carried out the fixed difficult problem of snow net admittedly, has realized the snow on the project concrete basement slide and has solidified the fixed of snow net drawknot board. The fixing device is suitable for fixing the snow fixing net drawknot plate based on the concrete base slideway.
The utility model discloses a drill the blind hole on the concrete substrate, use the compressed air to blow the blind hole clean up; then injecting a proper amount of anchoring glue into the blind hole, implanting the stainless steel internal thread sleeve into the blind hole, enabling the upper end surface of the sleeve to be flush with the upper surface of the concrete, and firmly fixing the stainless steel internal thread sleeve after the anchoring glue is solidified; and screwing a slotted flat-end fastening screw into the stainless steel internal thread sleeve, laying a hydrophobic plate, mounting the snow fixing net drawknot plate on the screw, and fixing the snow fixing net drawknot plate by using a large hexagonal nut unstrained spirit spring washer. The method solves the difficult problem of fixing the snow fixing net on the concrete base, and realizes the fixing of the snow fixing net drawknot plate of the concrete base slideway of the snowing project.
The utility model discloses a concrete foundation 1, hydrophobic plate 2, solid snow net drawknot board 3, stainless steel internal thread sleeve 4, anchor glue 5, fluting flush end holding screw 6, big hexagon nut 7, spring washer 8. Drilling a through hole on a concrete substrate 1, injecting an anchoring adhesive 5 into the through hole, implanting a stainless steel internal thread sleeve 4 into the through hole on the concrete substrate 1 in which the anchoring adhesive 5 is injected, fixing the stainless steel internal thread sleeve 4 on the concrete substrate 1, screwing a slotted flat end fastening screw 6 into the stainless steel internal thread sleeve 4, laying a hydrophobic plate 2 on the concrete substrate 1, and installing a snow fixing net drawknot plate 3 on the slotted flat end fastening screw 6 and fixing the snow fixing net drawknot plate with a large hexagon nut 7 unstrained grain spring washer 8.
The stainless steel internal thread sleeve 4 is implanted into the through hole on the concrete substrate 1 which is injected with the anchoring adhesive 5, the upper end of the stainless steel internal thread sleeve is aligned with the upper surface of the concrete, and the stainless steel internal thread sleeve 4 is fixed on the concrete substrate 1 after the anchoring adhesive is solidified, so that a firm whole is formed.
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 the large hexagon nut 7 unstrained spirits spring washer 8, and the snow fixing net drawknot plate is fixed 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.
The utility model provides a concrete base carry out the fixed difficult problem of solid snow net, realized on the snow fixing of project concrete base slide and drawn the fixed of knot board. Has the advantages that: novel structure, safe and reliable, assembled degree height have solved the concrete foundation and have carried out the fixed difficult problem of snow-fixing net, have realized the fixed of snow project concrete foundation slide snow-fixing net drawknot board on the snow.
