Composite joist floor system

Номер: US20130008112A1
Автор: David Lee Samuelson, Glenn Wayne Studebaker, Lionel Edward Dayton
Принадлежит: Nucor Corp

The composite joist floor system includes joists supported by supporting members. Corrugated steel decking is positioned over the joists such that the corrugations are substantially perpendicular to the joists. Self-drilling, self-tapping, stand-off screws are spaced along the length of the joist, aligned with the deck corrugations. These stand-off screws provide the required shear transfer between the joist and concrete slab to form a composite floor system. The placed concrete encapsulates the upper non-threaded shank portions of the stand-off screws and the end of the joists. After the concrete has cured, the resultant system comprised of steel joists, steel decking, stand-off screws, and concrete, act together to form a composite system with greater load carrying capacity and less vertical deflection. The stand-off screws connect the joist upper chords to the concrete slab allowing the joist and concrete slab to act as a unit, by transferring shear between the two joined components.

A fastener arrangement includes a threaded member having threads extending from a first end to a second end. The threads have a thread contour provided by a load and clearance flank surfaces joined to one another by a crest and root. For the external threaded member the crest provides a crest diameter, and a root provides a root diameter and is arranged between adjoining threads. At least one thread near the first end has a weakened thread contour that decreases rigidity of the one thread compared to other threads, enabling axial loads to be distributed more evenly between the threads.

Phosphated screw which after phosphating is provided with a siliceous sealing layer and has been rolled only after phosphating and after application of the siliceous sealing layer. 1. A phosphated screw characterised in that the screw is provided with a siliceous sealing after phosphating.2. The phosphated screw according to claim 1 , characterised in that the screw is rolled only after phosphating and the application of the siliceous sealing. The present invention relates to a phosphated screw.Currently in the motor industry, all internal engine screws are phosphated and subsequently oiled in order to maintain a certain resistance to corrosion and a defined coefficient of friction in accordance with OEM and German automobile industry standards. This creates the problem that the necessary oiling renders the screws so oily that oil residues collect in the transport packaging, which must be cleaned before being returned. In addition, the excess oil dirties the automatic assembly systems. These systems must then be cleaned frequently, resulting in the system having to remain idle unnecessarily. The application of oil also causes any dirt or debris which comes into contact with the screws to adhere thereto. In the case of large foreign bodies, this can lead to incorrect screw-fitting.Based on this prior art, the object of the present invention is therefore that of creating phosphated screws which do not require oiling, and which nevertheless have the necessary resistance to corrosion and in particular the predetermined coefficient of friction.Previous attempts to solve this problem have involved providing screws with solid film lubricants and the like. Solid film lubricants, however, have the disadvantage that they are either too thick, produce too much abrasion or are not sufficiently resistant to pressure.Different oil blends were also tried, but these too gave unsatisfactory results.According to the invention, the above-mentioned object will be solved for the first ...

QUICKLY RELEASABLE LINER BOLT

Номер: US20150028142A1
Автор: Coray Dale
Принадлежит:

A nut () and a re-usable liner bolt () for a grinding mill is disclosed. The nut is shaped to be received in the recess () of a mill liner plate (), this being the recess which normally receives the head of a conventional liner bolt. The nut is provided with a blind threaded hole (). The re-usable bolt has a stepped shank () and a thread () on its free end. The bolt () is inserted from the exterior of the mill and engages the nut (). The fines produced during grinding cement the nut to the liner but do not cement the bolt to the liner or the bolt to the nut. The head of a conventional liner bolt is located within the mill and its conventional nut is located exterior of the mill, whereas the re-usable bolt () has its head exterior of the mill and its nut () interior of the mill. Methods of assembly and dis-assembly of the bolt () and nut () are also disclosed. 1. A liner nut having an exterior surface and a blind threaded hole , said exterior surface being shaped to mate with a recess in a grinding mill liner plate to thereby prevent rotation of said nut relative to said recess , said blind threaded hole being located in a protruding portion of said nut which is dimensioned to extend through said liner plate recess and beyond said liner plate.2. The liner nut as claimed in wherein said exterior surface has the shape of the head of a liner bolt previously received in said recess.3. The liner nut as claimed in wherein said exterior surface is substantially oval.4. A liner bolt having a head claim 1 , a shank extending from said head and having a transverse extend less than the transverse extend of said head claim 1 , and a threaded portion of said shank adapted to threadably engage with the threaded blind hole of the liner nut as claimed in claim 1 , the length of said threaded portion not exceeding the length of said protruding portion.5. The liner bolt as claimed in and having a head with an internal drive recess.6. The combination of a liner nut having an exterior ...

A method of installing pre-molded seal caps onto fasteners that extend from a surface comprises sequentially delivering the pre-molded seal caps, arranged on a carrier strip, to a plunger mechanism via a feed system. The method also comprises sequentially removing the pre-molded seal caps from the carrier strip using the plunger mechanism, operating in concert with the feed system. The method further comprises individually installing the pre-molded seal caps onto selected ones of the fasteners using the plunger mechanism. 1210301300500. A method of installing pre-molded seal caps () onto fasteners () that extend from a surface () , the method () comprising steps of:{'b': 210', '200', '220', '230, 'sequentially delivering the pre-molded seal caps (), arranged on a carrier strip (), to a plunger mechanism () via a feed system ();'}{'b': 210', '200', '220', '230, 'sequentially removing the pre-molded seal caps () from the carrier strip () using the plunger mechanism (), operating in concert with the feed system (); and'}{'b': 210', '301', '220, 'individually installing the pre-molded seal caps () onto selected ones of the fasteners () using the plunger mechanism ().'}2. The method according to claim 1 , further comprising:{'b': 220', '301', '210', '301, 'determining an angular orientation of the plunger mechanism () relative to the selected ones of the fasteners () prior to individually installing the pre-molded seal caps () onto the selected ones of the fasteners (); and'}{'b': 210', '301', '220', '301, 'individually installing the pre-molded seal caps () onto the selected ones of the fasteners () only when the angular orientation of the plunger mechanism (), relative to each of the selected ones of the fasteners (), is a pre-determined angular orientation.'}3210301220301220301. The method according to claim 2 , further comprising claim 2 , while individually installing the pre-molded seal caps () onto the fasteners () claim 2 , indicating that the plunger mechanism ...
