专利汇可以提供System for fabricating structural members专利检索，专利查询，专利分析的服务。并且A system for making joists including the steps of forming a zigzag-shaped web midsection and opposite ends adapted to fit together to provide a continuous joist web of predetermined depth and length, forming a bottom chord to extend between the opposite ends of the bottom of the web, assembling said web and bottom chord, forming a top chord, mounting shoes and plugs on the top chord, aligning the top chord with the assembled web and bottom chord, tacking an end of the web and the top chord which are in registry to maintain the alignment, and completing connection of the top chord and web to form a finished joist.，下面是System for fabricating structural members专利的具体信息内容。
1. In a method for fabricating a structural member comprising the steps of shaping a longitudinally extending intermediate member so as to provide a first and a second set of peripherally aligned stress points; forming a first longitudinally extending side member of sufficient length to connect said first set of peripheral stress points; connecting the intermediate member with said first longitudinally extending side member along said first set of stress points; forming a second longitudinally extending side member of sufficient length to connect said second set of peripheral stress points; connecting the intermediate member with said second longitudinally extending side member at a predetermined one of said second set of stress points; locating said second longitudinally extending side member with respect to said first longitudinally extending side member and in predetermined relationship with said intermediate member, and connecting said second longitudinally extending side member to said intermediate member at said second set of stress points.
2. The method of claim 1 including a step of clamping said located second longitudinally extending side member prior to its being connected with said intermediate member.
3. The method of claim 1 wherein said shaping step for said intermediate member includes forming opposite end portions of the latter so that two more stress points are provided in one of said respective first and second set of stress points and forming one of said longitudinally extending side members connected with said greater number of stress points longer than said other longitudinally extending side member.
4. The method of claim 1 wherein prior to said step of connecting said second longitudinally extending side member, are included the steps of locating one end of said member in respect of a predetermined reference point on said intermediate member, and clamping said longitudinally extending side member together with said intermediate member.
5. In a method for fabricating a joist, comprising the steps of forming a web into a generally zigzag shape of predetermined depth and length and having respective top and bottom stress points located along opposite side; forming a bottom chord having a predetermined length and adapted to connect said respective web bottom stress points; connecting said web with said bottom chord at said bottom stress points; forming a top chord having a predetermined length and adapted to connect said respective web top stress points; aligning said top chord wiTh said web top stress points and in predetermined registry with said assembled web and bottom chord; clamping said top chord and said web together in aligned and registered relationship; fastening said top chord and said web sufficiently to maintain substantial alignment and registry; locating said top chord in precise spaced relationship with respect to said bottom chord and in contact with said web top stress points, clamping said top chord and said web together, and; fastening said top chord and said web at said web top stress points.
6. The method of claim 4 wherein one of said longitudinally extending side members is adapted to form a part of a top chord and including prior to the step of aligning said one longitudinally extending side member with the associated stress points of said intermediate member, the additional step of reinforcing said top chord at predetermined positions along the length of said top chord.
7. The method of claim 5 and including the step of placing mountings at opposite ends of said top chord prior to said top chord aligning step.
8. In a method for fabricating a structural member, comprising the steps of shaping a longitudinally extending intermediate member so as to provide a first and a second set of peripherally aligned stress points; forming a first longitudinally extending side member of sufficient length to connect said first set of peripheral stress points; connecting the intermediate member with said first longitudinally extending side member along said first set of stress points; forming a second longitudinally extending side member of sufficient length to connect said second set of peripheral stress points; connecting the intermediate member with said second longitudinally extending side member at a predetermined one of said second set of stress points; locating said second longitudinally extending side member with respect to said first longitudinally extending side member and in predetermined relationship with said intermediate member; locating one end of said second longitudinally extending side member in respect of a predetermined reference point on said intermediate member; clamping said second longitudinally extending side member together with said intermediate member; connecting said second longitudinally extending side member to said intermediate member at said second set of stress points; inspecting the assembly of the side members and intermediate member; and providing additional fastening at selected points of contact therebetween.
9. The method of claim 3 and including a step for connecting predetermined struts to said web.
10. In a mechanism adapted to align and register first and second longitudinally extending parts of a structural member, the combination comprising a platform for receiving the first longitudinally extending part; a first means along one side of said platform for guiding the second longitudinally extending part into proximity with one side of the first longitudinally extending part; a second means along an opposite side of said platform engaging the opposite side of the first longitudinally extending part to guide the latter into aligned relationship with the second longitudinally extending part; a selectively operable clamp cooperating with said second guide means for gripping the first longitudinally extending part; means selectively positionable a predetermined distance beyond said clamp and associated with the first guide means in the path of movement of the second longitudinally extending part to facilitate positioning the end of the latter; and means associated with said first guide means for clamping together the proximate portions of the first and second longitudinally extending parts.
11. The mechanism of claim 10 and including in combination means for adjusting said second guide means laterally relative to said first guide means to accommodate different size structural members.
12. The mechanism of claim 10 and including in combination an indicating means for said sTop to facilitate aligning and registering different length structural members.
13. The combination of claim 10 where said first means is a set of roller wheels adapted to guide a joist top chord angle and said second means is an upright roller adapted to guide a longitudinally extending joist bottom chord.
